Floor screed support

Application filed January 31, 1930. Serial No. 424,821.

This invention relates to floor screed supports.

The invention has for an object the provision of a screed support which may be read0 ily driven into any object without the necessity of first drilling a hole in said object.

Another object is the provision of a screed support which is readily adjustable as to height above an object and which is so con10 structed as to readily center and hold any type of screed.

Another object is the provision of a screed support so constructed and arranged as to prevent material used in the construction of 16 say a building, from in any way interfering or lifting the screed relative to the support so that the screed does not indicate true level.

Screeds are ordinarily used in buildings where floors are to be poured out of concrete SO or cement, and the height of the bracket carried by a suitable post, plus a screed or screeds carried by two or more of said brackets, indicates the height of the flooring to be poured. It is necessary during the pouring operation ²⁶ that material should not interfere with the screed support or get beneath the screed and support so as to raise the screed and therefore bring the floor out of level.

The present invention accomplishes this 80 much desired function in a novel and simple manner.

The invention likewise provides a screed support including a standard or post which is arranged to be readily driven into an object ⁸⁸ and limited as to inward movement so .that the height of all of the standards relative to the supports may be accurately gaged.

The invention has for a further object the provision of a screed support which is simple ⁴⁰ of structure, inexpensive of manufacture and generally superior.

' With the above and other objects in view, the invention consists in the novel and useful provision, formation, construction, asso⁴⁸ ciation and relative arrangement of parts, members and features, all as shown in a certain embodiment in the accompanying drawings, described generally and more particularly pointed out in the claims.

⁸⁰ In the drawings:

Figure 2 is a side elevation, partly in section_; of the improved screed support. 55

Figure 3 is a top plan view of the showing in Figure 1, and,

Figure 4 is a cross sectional view on the line 4—4 of Figure 3.

Referring to the drawings, I have shown 60 at A a building in the course of construction, and this may illustrate a floor construction wherein we have beams and joists. Of course, ordinarily flooring may be employed, or metal lathing or the like in accordance with the 65 character of the building being constructed, such as a poured concrete building or a combination steel structure and poured concrete floorings and ceilings. In order to regulate the height to which the concrete is to 70 be poured, what is known as a scraper or leveling device is employed between two screeds a, these screeds being spaced apart a suitable distance and generally substantially parallel as shown in Figure 1. The ⁷⁵scraper is not shown, but simply comprises wood or metal having a part slidable upon the screeds and a part depending therebetween. In the present instance, the screeds may be iron rods, wooden members, such as ⁸⁰so-called 2 x 4s, or the like. The screed support is designated as δ and the supporting standard by c. The supporting standard in the present instance is formed of metal tubing, one end of which carries an impaling de- ⁸⁵vice 1 in the form of a pointed stud and which impaling device is secured to a block 2 received within the tubing and secured by a transverse pin 3 to said tube. The bracket δ is slidable relative to said standard and like- ⁹⁰wise may be held in any adjusted position relative to said standard by a suitable adjusting screw 4. The bracket includes an enlarged portion 5 formed with a bore 6 through which the standard is adapted to pass and ⁹⁸this portion 5 may form an integral part of or a separate part of a U-shaped member designated generally as 7. This member includes a base portion 8 and two arms or leg portions 9 and 10 extending therefrom, and ¹⁰⁰

1,882,673 which arms or leg portions lie in substantially the same plane. The arrangement is such that the arm or leg 10 will have the face 11 abutting against the periphery of the • standard when the bracket is carried by said standard, as shown in Figure 2. The oppositely facing portions of the arms or legs are relatively inclined outwardly from the base portion as shown at 12 and 13. The base por¹⁰ tion and particularly that portion lying between the two legs is wedge-shaped, as shown in Figures 3 and 4 at 14. In other words, the edge is comparatively sharp with abruptly diverging sides.

¹⁸ The operation of the invention is as follows :

We assume that a floor is to be poured with concrete. The operator will possibly remove the bracket from the standard and the operator will drive with a hammer or suitable means the impaling portion 1 into a beam, girder or joist, further movement of the bracket being stopped when the bracket shoulders itself. against the beam, it being noted that the impaling device is of lesser diameter than the diameter of the standard. After the different standards are in position, the brackets are adjusted thereon to the proper height by measurement in the ordinary manner. The screeds a are then placed in position on the brackets and it will be noted that the screed will rest upon the substantially sharp edge 14 of the base portion. The usual scraper will extend between the two parallel screeds.» and the floor will be poured. After the floor is poured, the screeds may be readily removed from the brackets and the standard pulled from the beam, joist or ₄₀ girder.

Assume, however, that the rod type of screed a is not used. In this instance, we may use the ordinary 2x4 wood members and it will be noted that these 2 x 4’s will be received _<6 between the two arms or legs 9 and 10 and may be driven therebetween. The arms or legs have the inner faces 12 and 13 inclined relative to. the base. Thus, this type of screed may be driven between the arms or legs.

^anY ^concrete or'other cementitious material is received beneath the screed and the bracket, it is evident that this concrete cannot disturb the screed or tend to lift it due to the fact that the base portion presents a ^r?lati^veIy sharp edge 14 and abrupt angular sides so that the concrete has no place to stick to the base. In other words, it cannot lodge thereon as would be the case if the base had a substantially flat face. It is an easy matter co re^move I'he screed due to the inclined, oppositely facing portions of the arms or legs.

The invention thus presents many features of advantage as was pointed out in the objects but by way of summary, it may be said that C5 ^^{le s}pPP⁰¹‘t is. self-leveling as to size, due to the difference in diameter between the impal ing portion and the main body of the standard, which assures that all standards will be positioned in an exact manner on all of the beams, and further that the brackets may be adjusted relative to the beams or girders on 70 said standards with assurance that they will be all substantially at the same height relative to their respective standards, and. furthermore, that the bracket will not hold the cementitious material or in any way inter- 76 fere with the screeds. ,

It is obvious that various minor changes and modifications and variations may be made in practicing the invention in departure from the particular showing of the draw- 80 ings without departing from the true spirit of the invention.
