[Detailed explanation of the device]

(Field of the Invention) This device is related with the joint structure of the joist in rear Body, such as a track. (PRIOR ART) Joint structure of the joist in rear Body, such as the former and a track, After making the plate which constitutes rear Body loading a heavy load by making main sill and main sill cross, and consists of steel in the intersection pinch so that it can fully respond to loading of a heavy load, The thing which screw on one and it makes it come to combine with it with an anchor bolt is common. (The issue which a device tends to solve) however -- the thing which makes it come in the above-mentioned conventional thing inside in the intersection of the main sill and main sill which support rear Body to pinch the plate of steel the path of the penetration hole drilled in the plate by above-mentioned steel in order to take the assemblability by an anchor bolt into consideration -- the path of an anchor bolt -- usually -- 0.~1 and an Omm grade -- since it enlarges When vehicles run a slope or a concavo-convex way, torsion happens to vehicles, as a result, gap arises in main sill and main sill, main sill is worn with the plate currently pinched between main sills, and an unpleasant allophone is generated. Therefore, in order to prevent the allophone depended to wear the main sill and the plate which happen by the torsion concerning these vehicles, The projection to a plurality of up-and-down directions is arranged on the plate pinched between main sills, Although main sill and main sill are made to consume this projection by combination by screwing of an anchor bolt and what is going to prevent gap of the main sill according a slope or a concavo-convex way to a run (JP,1-82979,U) is proposed by the same applicant as this device, Although the gap of the main sill by run can prevent a slope or a concavo-convex way certainly by a plurality of projections arranged on a plate, If a joist contracts by dryness etc. since the quality of the material which constitutes a joist is wood, The conclusion power by an anchor bolt declines, it produces in the big gap between main sills, and breakage of the fiber layer of wood occurs by the projection of the plate pinched between the above-mentioned joists, and there is a fault to which the fall of the intensity of the joist itself takes place. It is although the thing (JP,60-5979,U) through the spacer which consists of plywood is between main sills, From being what the spacer which the object aims at reservation of a tire house and is pinched between joist material depends on plywood, Since the intensity of the spacer itself which cannot prevent the allophone by gap of a joist and consists of plywood is low, the fall of the supporting strength of rear Body loading a heavy load is not escaped, either. It is although the application of grease, wax, etc. and use of a resin liner are also considered in order to prevent generating of the allophone in the intersection of the joist, From the quality of the material of a joist being wood in the application of grease, wax, etc., Osmosis into a joist takes place by prolonged use, and it cannot fully prevent generating of the allophone by gap of main sill, What construct in the case of grease, protrude With at the time of work, and remarkable corruption is caused, and also uses a resin liner, In the severe track of the environment, etc., it is easy to generate invasion of an impurity, wear of the resin liner by an impurity occurs, and there is a fault used as what has the rise of cost low endurance and large. then, this device tends to improve the fault which the above-mentioned conventional thing has, and tends to prevent the allophone which is made by gap which boils a joist and occurs according to an easy structure. (Means for solving problem) Therefore, the plate which made both sides crooked in the intersection of main sill and main sill below, and pasted up the nonwoven fabric on it at the rest is made to intervene, and it makes it come to combine the above-mentioned cross sill and main sill with one with an anchor bolt. (OPERATION) Since it has the above composition, vehicles run a slope or a concavo-convex way, Even if the penetration hole drilled in a plate in consideration of the assemblability of a joist is made into path size rather than the path of the anchor bolt and gap arises in main sill as a result, Since generating of an allophone can be prevented since the 0.2~0.5-mm-thick nonwoven fabric has pasted the rest of the plate which intervenes between main sills, and also wear by gap of this cross sill can be prevented, the fall of the supporting strength on structure can be prevented. (EXAMPLE) The example shown in a figure further explains this device. (1) is rear Body, such as a track provided with the joint structure which is an example of this device, and this rear Body (1) is, The loading platform (2) loading cargo and this loading platform (2) are supported, it comprises the main sill (3) and main sill (4) which are wooden, and the above-mentioned main sill (3) and main sill (4) are combined with one in that intersection (5) with an anchor bolt (6). And in the intersection (5) of this main sill (3) and main sill (4), In the rest (9) made into the plane which uses both sides as a flection (8) and has a penetration hole (11) in the center, The plate made from steel (7) on which the 0.2~0.5-mm-thick nonwoven fabric (10) was pasted up is made to intervene between main sills (3) (4), and is made into one with an anchor bolt (6). Since this device is provided with the above composition, when vehicles run a slope or a concavo-convex way, the assemblability of main sill (3) and main sill (4) is taken into consideration, Even if the margin is given to the penetration hole (11) of the center of the plate made from steel (7) and gap of main sill (4) produces this slope or a concavo-convex way by run in it by considering it as path size rather than the path of an anchor bolt (6), In the rest (9) of the plate made from steel (7) by which it is placed between the intersections (5) of main sill (3) and main sill (4), Since the 0.2~0.5-mm-thick nonwoven fabric (10) has pasted up, it can prevent generating an allophone etc. and also can also prevent wear between the main sills (3) which arise by gap of main sill (4). The relation of the apparatus which chassis frame (12) group width is changing, or it attaches to a chassis frame (12) as shown in Drawing 5, In the case of the vehicles which the screwing position of the anchor bolt (6) which combines the main sill (3) and the chassis frame (12) of rear Body (1) with one cannot set as the front end of main sill (3) The hit side (13) of main sill (3) may be made to join a nonwoven fabric (10) to a chassis frame (12) directly. (Effect of a device) While heightening the sound isolation effect under run by preventing the allophone which occurs by gap of main sill by pinching the plate made from steel which joined the nonwoven fabric in the intersection of a joist as above, Since the intensity of the joist which supports a loading platform by preventing wear of a joist is raised, it has the outstanding effect which can improve the endurance of rear Body.
