している。
Traditionally, to construct reinforced concrete slabs,
The method used was to combine formwork to partition the space that forms the floor slab, place reinforcing bars in this space, pour concrete, and then remove the formwork after the concrete hardens. Currently, there is a disadvantage that construction costs are extremely high, as it requires a great deal of labor such as assembling, removing, transporting, and organizing a large number of materials such as formwork and supports, and applying release agent to the formwork surface. The so-called dumping method, in which the formwork is integrally buried in concrete without removing it, is becoming popular.

For this reason, a flat deck plate disclosed in Japanese Utility Model Application Publication No. 56-41012 has recently been developed and used. As shown in FIG. 1, a plurality of reinforcing ribs 2 having a hollow triangular cross section are bent in parallel at regular intervals on the lower surface side of a horizontal plate 1, and a connecting piece 3 is formed at one end parallel to the reinforcing ribs 2. FIG. 2 shows a flat deck plate 5 formed by folding down the reinforcing ribs 2 and crushing both ends of the reinforcing ribs 2 to form planar mounting pieces 4 at both ends of the plate 1 perpendicular to the reinforcing ribs 2. The top surface of the flat deck plate 5 and the top surface of the steel beam 6 are set to be approximately on the same plane, and the distance from the top surface of the steel beam 6 to the top of the concrete is This saves on concrete and finishing materials, and also eliminates the need to close the ends of the reinforcing ribs.

By the way, the flat deck plate 5 is
To connect the steel beams 6 on both sides, the connecting piece 3 at one end is press-fitted into the reinforcing rib 2 at the other end of the adjacent flat deck plate 5, as shown in FIG. There is. In addition, as shown in FIG. 4, in the case of a flat deck plate 5' having two L-shaped reinforcing ribs 2' folded over, the connecting piece 3 at one end is connected to the other side of the adjacent flat deck plate 5'. It is press-fitted into two reinforcing ribs 2' at the end.

In order to connect the flat deck plates 5, 5' in this manner, the connecting piece at one end is press-fitted into the reinforcing ribs 2, 2' at the other end. Since it is easy to lift up and therefore easily come off, it must be fixed by welding, etc. In addition, the reinforcing ribs are expanded by press-fitting the connection pieces, reducing their strength, and when concrete is poured,
There was a risk that the connection would become dented.

A joint that is connected to one side end (the right end in the figure) of the plate 1 parallel to the reinforcing rib 2, has a V-shaped cross section, and has an L-shaped bent piece 8 located inside and below the upper edge of the V-shaped outer side. 9 is formed, and both ends (front and rear ends) of this joint 9 are crushed like the above-mentioned frame piece 4. At the other end parallel to the reinforcing rib 2 (the left end in the figure) is an insertion piece 10 to be inserted into the joint 9.
is formed. This insertion piece 10 has the other end of the plate 1 bent downward and inclined inward, and both ends (front and rear ends) thereof are cut off. The upper edge of the V-shaped outer side of the joint 9 is lower than the upper surface of the plate 1 by the thickness of the plate 1. Further, the gap 11 between the V-shaped inner side of the joint 9 and the L-shaped bent piece 8 is made to have the same dimension as the thickness of the plate 1.

The flat deck plate 12 of the present invention configured as described above is mounted between the steel beams 6 (see FIG. 2) using the mounting pieces 4, and the flat deck plate 12 is
The upper surface and the upper surface of the steel beam 6 are set to be substantially the same plane, and the same flat deck plates 12 are successively mounted and connected in the longitudinal direction of the steel beam 6. That is, as shown in FIG. 6, the insertion piece 10 at the other end of the adjacent flat deck plate 12 is continuously inserted into the gap 11 in the joint 9 having a V-shaped cross section at one end of the flat deck plate 12. Then, each flat deck plate 12 is mounted between the steel beams 6. At this time, each flat deck plate 12 is on the same plane because the upper edge of the outer side of the V-shape of the joint 9 is lower than the plate 1 by the thickness of the plate 1. In addition, even if the insertion piece 10 inserted into the gap 11 of the joint 9 tries to lift up, it is in close contact with the V-shaped inner side (left side) of the joint 9, so its frictional resistance prevents it from lifting up and allows it to come off. Moreover, since the reinforcing rib 2 is not press-fitted with the insertion piece 10, it will not be expanded and its strength will decrease, and therefore, when concrete is poured, the connection part will not be dented. .

Next, another embodiment of the flat deck plate according to the present invention will be described with reference to FIG. Since the same reference numerals in the figure as in FIG. 6 indicate the same parts, the explanation thereof will be omitted. This flat deck plate 12' is
Joint 9 at one end (right end) parallel to reinforcing rib 2
The L-shaped bent piece 8 is made smaller to increase the gap 11 between it and the V-shaped inner side of the joint 9.

This flat deck plate 12' is also successively mounted between the steel beams 6 and connected to the adjacent flat deck plate 12', as in the previous embodiment.
That is, as shown in FIG. 7, the gap 11 in the joint 9 at one end of the flat deck plate 12'
Then, the insertion piece 10 at the other end of the adjacent flat deck plate 12' is successively inserted to connect and mount the flat deck plate 12' between the steel beams 6. In this case, since the gap 11 in the joint 9 is large, the insertion piece 10 can be easily inserted. The lifting of the insertion piece 10 is the same as in the previous embodiment.
Since it is in close contact with the inner side (left side) of the V-shaped joint 9, its frictional resistance prevents it from coming off.

As can be seen from the above explanation, when the flat deck plate of the present invention is successively mounted between steel beams and connected to an adjacent flat deck plate, the V
The connection can be made by simply inserting the insert piece at the other end of the adjacent flat deck plate into the shaped joint from above, making it extremely easy to work with. In addition, the insertion piece sticks closely to the inside edge of the V-shape of the joint, and the frictional resistance prevents it from lifting up and coming off, so there is no need to weld it in place like in the past, and concrete is poured onto the flat deck plate. There is no leakage when installed, and since the reinforcing ribs are not press-fitted with insertion pieces, there is no possibility of the reinforcement ribs being expanded and decreasing in strength. Therefore, there is no possibility that the connecting portion will be dented by concrete pouring, and the reinforced concrete slab can be constructed safely and accurately.
