CN2385028Y - Steel load-bearing floor slab with concavo-convex knurling - Google Patents

Abstract

The utility model relates to a steel load bearing floor plate with concave-convex embossing, which is composed of bearing plates and embossing, wherein, the side faces of the bearing plates are provided with concave-convex embossing. The concave-convex embossing can forms a triangle shape, a quadrangle shape and a circle shape; every two or three of the bearing plates can be divided into one group to be connected into an integral body. The utility model has the advantages that when concrete is formed, the concave-convex embossing acts a buffer function to avoid the formation of bubbles when filling the steel bearing floor plate with the concrete, and increases the bearing capacity and the shear resistant capacity of the floor bearing plates obviously.

Description

Steel with concavo-convex knurling holds floor

The utility model is a kind of building form, particularly a kind of steel board with concavo-convex knurling.

Sell the 3W-DECK steel at present on the market and hold floor, because of there is obvious corner at its embossing position, thereby when concrete pouring, makes gas to discharge and in concrete, produce bubble, influence casting quality; The floor contact area is less because concrete and 3W-DECK steel hold, and the bond stress that concrete and 3W-DECK steel are held between the floor is less, for improving this situation, the general way of adding concrete reinforcement that adopts.

The purpose of this utility model is to provide a kind of steel with concavo-convex knurling to hold floor, and it can hold floor with steel after the concrete pouring maintenance is finished and beam combines the formation combining structure, and has significantly increased supporting capacity and shear resistance.

The purpose of this utility model is achieved in that a kind of steel board with concavo-convex knurling, is made up of board and embossing, is provided with cancavo-convex embossing in the board side; The concavo-convex knurling that steel with concavo-convex knurling holds floor can be triangle, quadrangle, circle; Steel with concavo-convex knurling holds floor and can be two or three boards and fuse for one group.

The utility model has the advantages that: embossing plays cushioning effect when concrete pouring, concrete can progressively fill up steel and hold concavo-convex knurling on the floor, produce bubble in the time of can avoiding concrete-filled steel to hold floor, significantly increase supporting capacity and shear resistance that steel holds floor.

Fig. 1 is a schematic perspective view of the present utility model.

Fig. 2 is the utility model front view.

Fig. 3 is that the utility model A is to view.

Fig. 4 is the utility model A-A sectional view.

The part explanation:

The steel that 1------has concavo-convex knurling holds floor;

The 2-----board;

The 3-----embossing.

Below in conjunction with accompanying drawing architectural feature of the present utility model is described in further details.

As shown in Figure 1, be stereogram of the present utility model (its model is FE3W-DECK), as seen from the figure,

It is that steel plate is formed through the mould compacting that steel with concavo-convex knurling holds floor 1, and the thickness of steel plate can be 0.75mm, 0.90mm, 1.2mm, 1.5mm, and board 2 and embossing 3 are arranged on it, and present embodiment is by being to be one group by three boards to be formed by connecting.Be provided with cancavo-convex embossing 3 in board 2 sides; Concavo-convex knurling 3 can be triangle, quadrangle or circle; The embossing 3 recess degree of depth are 2 millimeters, and height of projection is 2 millimeters.Embossing 3 recessed with gross area projection should be greater than the embossing area of present commercially available floor support plate.

During use, steel board with concavo-convex knurling is placed on desired location, during concrete pouring, from bottom to top pass through embossing 3, the recess of embossing at this moment 3 plays cushioning effect to concrete, produce bubble when avoiding concrete to fill board 2, the very strong ability that bonds is arranged between board 2 and the concrete thereby make.

Claims (5)

1, a kind of steel with concavo-convex knurling holds floor, is made up of board and embossing, it is characterized in that being provided with cancavo-convex embossing in the board side.

2, the steel with concavo-convex knurling according to claim 1 holds floor, it is characterized in that concavo-convex knurling can be triangle, quadrangle, circle.

3, hold floor according to claim 1 or described steel with concavo-convex knurling, it is characterized in that the embossing recess degree of depth is 2 millimeters, height of projection is 2 millimeters.

4, hold floor according to claims 1,2 or 3 described steel, it is characterized in that board is two one group and fuses with concavo-convex knurling.

5, hold floor according to claims 1,2 or 3 described steel, it is characterized in that board is that triplets fuse with concavo-convex knurling.
