Installation work management system utilizing 3d-cad

The present invention relates to an installation construction management system utilizing 3D-CAD, which is suitable for construction planning and management of construction processes in plant construction.

A method of planning the entire construction process of a plant building using a 3D-CAD system has been proposed (for example, Patent Document 1). According to this method, a plurality of parts related to a series of construction work are grouped by using the attribute data (part type, caliber, connection relationship, etc.) of each part created by the 3D-CAD system, and the group unit. The construction process such as installation is examined and process data is created. In addition, the groups are integrated or divided and reorganized as needed. Furthermore, it has been proposed to rationalize the construction process creation by linking CAD drawing data and construction work and creating a process chart while confirming how to proceed with the construction of the plant with animation.

<p> However, the conventional technique described in Patent Document 1 has a problem that the following matters are not taken into consideration.</p><p> Construction at a construction site requires physical distribution management of materials at the construction site due to restrictions on the site area of the construction site or restrictions such as temporary storage outdoors such as precision equipment. In particular, no consideration is given to dynamically responding to changes in the receipt date of materials and the progress of construction work.</p><p> Further, if other materials or equipment are already installed on the carry-in route for bringing the materials to the installation location, the installation cannot be performed as it is, but conventionally, the interference check of the installation carry-in route has not been considered.</p><p> In addition, no consideration is given to the planning of installation work and installation process for the purpose of reducing the amount of temporary materials and construction man-hours by making the piping on-site block.</p><p> An object of the present invention is to provide an installation work management system capable of dynamically creating or changing an installation process in response to a change in a material receipt date or a progress of work.</p><p> Another issue is to provide an installation work management system that can dynamically create or change the installation work and the installation process by judging the presence or absence of interference in the installation carry-in route, the amount of temporary materials, and the construction man-hours.</p>

<p> The present invention solves the above problems by means described below. Basically, in plant design, 3D-CAD systems are often used to model the materials that make up the plant and create 3D drawings. At this time, the material model created on the 3D drawing is created by adding material data such as type, material, dimensions, weight, and user-defined information when the model is created. In addition, a structural model consisting of layout data such as layout information of the material model in the plant and connection relationships between materials is created. Therefore, the present invention constructs an installation work management system by using the material model database and the structural model database created at the plant design stage.</p><p> Specifically, the installation work management system of the present invention connects a plurality of the material models to a material model database in which a material model obtained by modeling a plurality of materials constituting the plant structure into a 3D-CAD model is stored. A structural model database in which the structural model to be configured is stored, an input means for inputting and setting installation data including a receipt date and an installation completion setting date of the material related to the structural model, and a designated date input by the input means. The installation work confirmation means for confirming the installation progress of the structural model in the above based on the installation data and displaying a 3D image of the structural model for which the installation has been completed based on the confirmed installation progress is provided on the display screen. It is characterized by being.</p><p> As a result, according to the present invention, when a designated date for which the installation progress is to be confirmed is input from the input means, the state diagram of the plant on that designated date is displayed as a 3D image. You can easily check the installation progress. In addition, when a change in the receipt date or installation completion setting date of the material related to the structural model is input from the input means, the 3D image changes dynamically in response to the change in the installation data. Fluctuations can be easily grasped.</p><p> In particular, it is preferable that the installation work planner can give a specific connection method and timing to the connection relationship between the materials input by the designer. In addition, the installation carry-in route of the structural model is formed so that it can be input and set in the installation data, and the installation work confirmation means determines whether or not the installation carry-in route of the material is interfered by the structural model whose installation is completed earlier. It is preferable that the carry-in route interference check means is provided. According to this, the installation work and the installation process should be dynamically created or changed by judging whether or not there is interference in the installation method and the installation delivery route in response to the change in the receipt date of the material and the progress of the construction. Can be done. Based on the results, it is possible to verify the installation plan and determine the impact on the plant delivery date. Therefore, by taking measures such as changing the structure of the structural model or changing the receipt date earlier, planning and management of the optimum delivery date Can be done.</p><p> Further, it is preferable that the installation work confirmation means is executed when the installation data set by the input means is changed. As a result, for example, if the installation planner changes, for example, the installation carry-in route in the installation data based on the result of the installation carry-in route interference check, whether or not the interference can be avoided according to the changed installation carry-in route. Can be grasped immediately. In this case, it is preferable that the installation carry-in route interference checking means display the structural model related to the installation carry-in route that receives the interference on the display screen so as to be identifiable. Further, it is preferable that the input means is displayed on the same screen as the input screen for inputting the installation data, side by side with the 3D image displayed by the installation work confirmation means.</p><p> Here, the material model can include material data of types, materials, weights, and dimensions, and the structural model can include arrangement data of arrangement positions, installation floors, and connection relationships between materials. In addition, the installation data can include temporary storage site information for materials related to the structural model.</p><p> Further, when the material model or the installation data is changed, the installation work confirmation means determines the amount of temporary materials and the construction man-hours required for the installation work of the structural model based on the changed material model, the structural model and the installation data. It can be calculated and added to the installation data.</p><p> In other words, the installation work management system of the present invention extends the scope of the model of the 3D-CAD system related to plant construction to the entire site site including the material storage area, warehouse and temporary factory, and orders materials (including equipment). It is possible to centrally manage the distribution information of materials on the site such as receipt, storage, and installation completion.</p>

<p> According to the installation work management system of the present invention, the installation process can be dynamically created or changed according to the change of the receiving date of the material and the progress of the work.</p><p> In addition, it is possible to dynamically create or change the installation work and the installation process while judging the presence or absence of interference in the installation carry-in route and comparing the amount of temporary materials and the construction man-hours.</p>

Embodiments of the present invention will be described with reference to the drawings. FIG. 1 shows an overall configuration diagram of an installation work management system according to an embodiment of the present invention, and FIG. 2 shows an outline of a processing procedure for installation work management according to the present embodiment. In addition, FIGS. 3 to 5 show detailed processing procedures for each part.

As shown in FIG. 1, the installation work management system 101 of the present embodiment includes a material model database 102, a structural model database 103, an installation data input means 104, an installation work confirmation means 105, and a 3D image display device 106. , So-called 3D-CAD system.

The material model database 102 stores a material model 107 formed by modeling various materials constituting a plant building by 3D-CAD. The individual material model i (i = 1, 2, 3, ..., N) 107 is given attribute data such as type 109, material 110, and dimension 111 as material data 108.

The structural model database 103 stores 3D-CAD data of all structural models 112 that make up the plant building. The structural model 112 is a model of a structure composed of a plurality of material models 107, and is appropriately defined by a plant designer using a group of materials composed of a plurality of materials as a structural model. In the illustrated example, the structural model j (j = 1, 2, 3, ..., K) 112 has the material model 107 constituting the structural model 112, the arrangement position 114 of the material model 107, and the material as the arrangement data 113. Attribute data such as the interconnection relationship 115 of the model 107 and the installation floor 116 in the building having the floor (floor) are given.

From the installation data input means 104, as the installation data 117, the materials constituting the structural model 112 are received at the construction site site 118, the temporary installation position 119, the installation completion setting date 120, the installation delivery route 121, and the materials. The interconnection relationship 122 is set as an input. The receipt date 118, the temporary placement position 119, the installation completion setting date 120, the installation carry-in route 121, and the material interconnection relationship 122 of the input-set installation data 117 are assigned to the structural model 112. Here, in the material interconnection relationship 122, the installation work planner gives a specific connection method and time to the material interconnection relationship 116 given by the designer.

The installation work confirmation means 105 includes a construction progress / work content confirmation means 123, an installation carry-in route interference check means 124, a temporary material amount calculation means 125, and a construction man-hour calculation means 126. The construction man-hours and the temporary material amount calculated by the temporary material amount calculation means 125 and the construction man-hour calculation means 126 are registered as the installation data 117.

Next, with reference to FIG. 2, an outline of the processing procedure for installation work management will be described. Following the start of processing (step 201), the plant designer creates a 3D image model of the plant building by arranging the already registered material model 107 as the structural model 112 on the 3D screen (step 202). At that time, individual arrangement data 113 is added to the structural model 112. The installation planner then inputs the installation data 117 (step 203). When the installation data 117 is input, the installation work confirmation means 105 is activated (step 204). Details of this step 204 will be described later with reference to FIGS. 3 to 5. Next, if the processing result of the installation work confirmation means 105 does not satisfy the installation completion setting date, or if there is an inconvenience such as the installation carry-in route interfering with other structural models, those installation data 117 are changed and the step is taken. Returning to 203, the above process is repeated (step 205). That is, the installation work is reexamined, the installation data 117 such as the receiving date, the installation delivery route, and the installation completion setting date is changed, and the installation data 117 is given to all the structural models j. When the installation work is no longer inconvenient in this way, the process of the installation work confirmation means 105 is terminated (step 206). As a result, the installation process can be determined while confirming the installation work from the 3D image from the site receipt to the installation completion setting date. In addition, it is possible to grasp the visualized in-site logistics.

Here, with reference to FIG. 3, the processing of the construction progress status / work content confirmation means 123 of the installation work confirmation means 105 will be described. The planner of the installation work either selects the date for which the work progress is to be confirmed as the designated date (X) 301 (step 301), or selects the structural model 112 for which the work progress is to be confirmed (step 302). Here, when the structural model 112 is selected, the installation completion setting date (X) of the structural model is extracted from the installation data 117 (step 303). The installation work confirmation means 105 extracts the consignment date (Aj) 118 and the installation completion set date (Bj) 120 of all the configuration models 117 (step 304), and compares the designated date X with the set date Bj or the consignment date Aj. (Steps 305a to 305c), the materials related to all structural models are automatically sorted into installed materials 306, construction materials 307, temporary materials 308, and unstarted materials 309.

Next, the planner of the installation work selects the display presence / absence / display color of the installed material 306, the construction material 307, the temporary material 308, and the unstarted material 309 (step 310). As a result, the progress status of the installation work and the distribution status of the materials of all the structural models can be easily confirmed by the 3D image identified and displayed on the 3D image display device 106 by color coding or the like according to the progress status of the installation work. In addition, the installation delivery route 312 of the material 307 under construction and the temporary site arrangement 313 of the material 308 temporarily placed are displayed on the 3D image (step 311). This makes it possible to easily check the distribution of materials required for installation, such as the installation work status, the receipt status, and the temporary storage site on the site.

FIG. 4 shows a detailed processing procedure of the installation carry-in route interference checking means 124. Following the start processing of the interference check means 124 (step 401), the installation planner selects the material for which the interference check of the carry-in route is to be performed on the 3D image (step 402). In response to this, the installation carry-in route interference checking means 123 automatically extracts the installation data 117 of the structural model related to the selected material (step 403). Then, the interference check of the installation carry-in route on the installation completion setting date of the selected structural model is performed (step 404). When the installation planner inputs a change in the installation data as necessary based on the result of the interference check (step 405), the installation carry-in route interference check 404 is repeated based on the changed installation data, and the installation carry-in route is changed. When the result that does not interfere with the material or structural model of is obtained, the interference check is completed (step 406).

Here, an example of a specific procedure for checking the interference of the installation carry-in route in step 404 will be described. As shown in Figure 4, the installation planner selects a structural model (step 404a). The installation delivery route of the selected structural model is 1 (X)₁, Y₁, Z₁), 2 (X₂, Y₂, Z₂), ..., i-1 (X_i-1, Y_i-1, Z_i-1), I (X)_i, Y_i, Z_i). Here, X, Y, and Z indicate coordinate positions on Cartesian coordinates, and i is a checkpoint counter set on the installation carry-in route. The installation carry-in route interference checking means 124 checks for interference on individual routes to checkpoints 1-2, 2-3, ..., I-1, i (step 404b). In this interference check, the selected structural model is continuously arranged on the route obtained by dividing the installation carry-in route by the number of divisions n (= 1 to K) determined by the installation planner (step 404c). Next, the number of divisions n is incremented from 1 to K (step 404d), and if there is interference such as contact with another structural model even if one of the arranged structural models is present, it is determined that there is interference (step 404f). If there is no interference in the determination of step 404d, the process proceeds to step 404e, the checkpoint i is incremented, and steps 404b to 404d are repeated. When these processes are executed and there is no interference in the installation carry-in route, it is determined that there is no interference and the process is terminated (step 404 g). The interference objects in this case are all the structural models that have been installed on the installation completion setting date of the selected material, and the interference check is performed by the above-mentioned 3D image of the installed material 306.

FIG. 5 shows the detailed processing procedure of the temporary material amount calculation means 124 and the construction man-hour calculation means 125 in the installation work confirmation means 105. Following the start of processing (step 501), the installation planner inputs a command for inputting installation data (step 502). As a result, the means for calculating the temporary material quantity and construction man-hours automatically affects the construction man-hours and temporary material quantity related to the structural model (type K, material M, weight T, dimension φ, connection relationship between materials). Extract Z, installation height H, etc.) from the material and structural models (step 503). Next, the coefficients Ki, Hi, Zi, Mi, ... Are extracted (step 504), and the construction man-hours and the amount of temporary materials are calculated (step 505). Here, the coefficient Ki and the like are preset based on data such as the material type K, the installation height H, the connection relationship Z between the materials, and the material M, which affect the construction man-hours and the amount of temporary materials. In addition, the weighting coefficient W, which indicates the importance of materials that affect the construction man-hours W,_T, Wφ, ..., and a weighting factor Q indicating the importance of the material that affects the temporary material quantity Q._K, Q_H, ... are preset. Further, these coefficients can be changed by changing the coefficient, the weighting coefficient, etc. depending on the difference in the land on which the installation work is performed, the quality of the workers, and the like. The construction man-hours and the amount of temporary materials calculated in step 505 are automatically input to the installation data (step 506), and this process ends (step 507).

As described above, according to the present embodiment, the installation process can be dynamically created or changed according to the change of the receiving date of the material and the progress of the construction. In addition, it is possible to dynamically create or change the installation work and the installation process by determining the presence or absence of interference in the installation carry-in route. As a result, it is possible to verify the installation plan and determine the impact on the plant delivery date. Therefore, it is possible to plan and manage the optimum delivery date by taking measures such as changing the structure of the structural model or changing the receipt date earlier. it can.

Further, according to the present embodiment, it is possible to dynamically manage the material distribution within the site, such as ordering, receiving, storing, and setting the installation schedule of materials (or equipment). In addition, by comparing the installation work, it is possible to study the optimum delivery time of materials and equipment and the efficient installation work procedure.

In addition, since the construction man-hours and the amount of temporary materials are calculated, the construction progress status and the work contents are displayed on the 3D image, it is possible to easily compare the suitability of the installation work.

Here, an embodiment in which the installation work confirmation means 105 of the above embodiment is applied to the installation work plan of the plant piping will be described with reference to FIGS. 6 and 7. The installation construction planner inputs installation data such as the installation completion setting date and the installation delivery route into each structural model while confirming the completed drawing of the plant using the 3D image shown in Fig. 6. The installation work confirmation means 105 automatically calculates the construction man-hours and the amount of temporary materials based on the given installation data, the material data 108 and the arrangement data 113 of each structural model, and displays them on the 3D image display device 106 or the like. And output it to inform the installation work planner. At the same time, the installation carry-in route interference check is automatically performed, and if there is interference, the display color of the structural model is changed to notify the installation construction planner that there is interference. The installation work planner changes the installation data while checking the 3D image, and completes the installation data without interference of the installation carry-in route.

Here, in the 3D plant completion drawing shown in FIG. 6, an example in which the installation work planner corrects while checking the installation work of the pipe P003 is shown in FIG. The piping P003 shown here is a piping group in which a plurality of material models having the same installation completion setting date and sharing a material interconnection relationship are automatically grouped. When the installation work planner selects the material model included in the piping group P003 as the piping to be corrected while confirming the installation work, the installation work confirmation means 105 automatically confirms the installation completion setting date of the piping group P003, and the installation completion setting date is confirmed. The plant installation status on the set date is displayed as a 3D image. In the example of FIG. 7, the piping groups P005 and P006 that have not been installed on the set date are not displayed in the 3D image. In addition, the welding points W001 to W010, which are the material interconnection relationships of each model, are displayed.

In the case of the example shown in FIG. 7, the welding points W001, W003, W004, W009, W010 are displayed as field welding, and the welding points W002, W005, W006, W007, W008 are displayed as factory welding. Since the piping groups P005 and P006 are not installed when the piping group P003 is brought in, it can be confirmed that there is no interference when the piping group P003 is brought in. Therefore, by using the local welding points W004 and W009 as local block welding, it is possible to reduce the work at heights and the associated temporary scaffolding assembly work, shorten the construction man-hours, and reduce the amount of temporary materials. ..

The installation work confirmation means 105 of the present invention can determine the validity of the change in the installation work when the set date for completing the installation of the pipe is changed due to a delay in delivery of the pipe or other factors in the actual construction. .. For example, when the installation data of the first embodiment is set in the 3D plant completion drawing shown in FIG. 6, an example will be described in which a change occurs in which the installation of the piping group P005 is desired to be completed before the installation of the piping group P003 is completed. ..

When the installation construction planner inputs the installation completion setting date of the piping group P005 on a date earlier than the installation completion setting date of the piping group P003, the length from the welding point W003 to the welding point W010 in the piping group W0003 is long by on-site block welding. Due to the change in the installation completion setting date of the piping group P005, the welded piping block interferes with the installation delivery route. In this case, since the display color of the 3D image of the piping group P003 is automatically changed, the installation planner can avoid the interference by changing the installation carry-in route or the welding method. For example, in the case of the example shown in FIG. 7, by changing the on-site block welding at the welding points W004 and W009 to on-site welding, it is possible to avoid interference by carrying in the pipes individually. At this time, the installation work planner can confirm by automatic calculation the increase in the construction man-hours and the amount of temporary assets due to the increase in the number of welded points at high places.
