Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a technique for applying an ALC slab to a floor beam formed of H-section steel.

[0002]

2. Description of the Related Art On both left and right edges of an ALC floor slab 35, steps 36 which are lower than the floor surface are formed along the side edges. Conventionally, this type of ALC floor slab 35 has been
When fixed to the floor beam, the tongue pieces 33 are welded to the surface of the floor beam at regular intervals substantially equal to the width of the ALC floor slab to protrude therefrom.
A through-hole 32 is formed in the tongue piece 33 in a direction perpendicular to the length direction of the ALC floor slab 35, and the side edges of the ALC slab 35 are aligned with a straight line passing through the hole 32 so that the ALC slab is arranged on the floor beam. The reinforcing bar 34 is placed in the groove 37 formed by the step 36 of the left and right ALC floor slabs 35 whose side edges face each other, and the tongue hole 32 is formed.
Mortar is poured into the groove 37 formed by the step 36 to embed the reinforcing bar 34, and the embedded reinforcing bar 34
A method of fixing the ALC floor slab 35 to the floor beam 31 via the slab is adopted.

[0003]

If the tongue piece 33 for fixing the ALC floor slab 35 is welded to the floor beam 31, the tongue piece 33 will be in the way until the ALC floor slab 35 is arranged on the floor beam 31. In addition, there is a risk that the tongue 33 trips, and if the projection interval of the tongue piece 33 is incorrect, welding must be performed again. In addition, there is a risk that the tongue piece 33 may be bent by hitting or catching an object.

[0004] In particular, there is a great risk that the tongue piece 33 is bent in the process of carrying the floor beam 31 produced at the factory to the construction site.

Therefore, the present invention aims to provide an ALC floor slab fixing hardware for securely fixing the ALC floor slab 25 to the floor beam 20 without welding the tongue piece 33 to the floor beam 20.

[0006]

Means for Solving the Problems That is, the AL according to the present invention
The C floor slab fixing hardware 24 has hooks 14 and 15 protruding from both left and right ends of one side of the steel plate piece 11 with the hook tips 12 and 13 facing inward, respectively. In the central part, a tongue piece 16 connects a straight line 17 connecting the hook 14 and the hook 15.
At the top end 19 of the tongue piece 16.
Has a shape for engaging a reinforcing bar 18 obliquely to a straight line 17 connecting the hook 14 and the hook 15, and a flange of an H-shaped steel 20 between each hook tip 12 and 13 and the steel plate piece 11. It is characterized in that the recesses 22 and 23 into which the fitting 21 is fitted are formed to face each other.

In order for the reinforcing bar 18 to be locked to the top end 19 of the tongue 16, a through hole 32 is formed in the tongue 16, or the top end 19 of the tongue 16 is hooked. What is necessary is just to cut it off so that the rebar 18 is hooked.

[0008] The tongue piece 16 is the reinforcing bar 1 locked to the tongue piece 16.
What is necessary is just to incline with respect to the straight line 17 which connects the hook 14 and the hook 15 so that the straight line 17 which connects the hook 8 and the hook 14 and the hook 15 may cross | intersect at an angle of 30 to 45 degrees.

The distance a between the opposed hooks 13 and 14 is equal to or slightly larger than the width b of the flange 21 so that the flange 21 of the H-section steel (floor beam) 20 can be fitted therebetween.

The ALC floor slab fixing hardware 24 includes a hook 14 and a hook 1.
5 is oriented at right angles to the length direction of the H-section steel (floor beam) 20, the ALC floor slabs 25 are arranged on the floor beam 20 at a predetermined interval, and the hooks 14 and 15 are directed downward. Then, the space between the hooks 13 and 14 is fitted to the flange 21 so that the steel sheet 1
1 is superimposed on the flange 21, and the whole is turned until the reinforcing bar 18 of the tongue piece 16 is orthogonal to the length direction of the H-section steel (floor beam) 20. Recess 2
The side edge of the flange 21 is fitted to 2 and 23 and fixed to the H-section steel (floor beam) 20.

The height of the tongue piece 16 is determined by the step 36 of the ALC floor slab arranged on the steel plate piece 11 with the tongue piece 16 thus fixed to the H-section steel (floor beam) 20 interposed therebetween. The reinforcing bar 18 to which the top end 19 of the tongue piece 16 is locked is formed in the groove 37 formed.
So that it sticks out.

When the ALC floor slab 25 is placed on an H-shaped steel (floor beam) 20 so as to be sandwiched between the reinforcing bars which are locked to the tongue piece 16 and arranged in parallel, the adjacent ALC floor slabs The mortar is cast into the groove 37 formed in the step 36, and at this time, the reinforcing bar 18 is embedded in the mortar. Therefore, the ALC floor slab 25 is connected to the floor beam via the mortar and the ALC floor slab fixing hardware 24. 20.

When the ALC floor slab 25 is mounted on the H-beam (floor beam) 20, the same thickness as the steel plate piece 11 is placed on the H-beam (floor beam) 20 between the ALC floor slab fixing hardware 24. Of cushioning material 10 and H-shaped steel (floor beam)
The undulations for the thickness of the steel plate pieces 11 are prevented from being formed on the arrangement surface of the ALC floor slabs 25 arranged in 20.

The reinforcing bar 33 is joined to the ALC floor plate 25 by mortar cast into a groove 37, and the tongue 16 and the hook 14
The wire or pipe (steel pipe) can be used as the reinforcing bar 33 because it serves as a “connector” for connecting the ALC floor slab 25 to the floor beam 20 via the wire 15.

[0015]

As described above, according to the present invention, there is no need to protrude the tongue piece 33 for joining the ALC floor slab 25 to the floor beam 20, and it is possible to save time and effort for welding it. Since the tongue piece 33 does not protrude, it is convenient for storage and transportation of the floor beam 20, and there is no danger of the tongue piece 33 tripping during the construction of the floor beam 20.

Since the ALC floor slab fixing hardware 24 is attached to the floor beam 20 at the construction site of the ALC floor slab 25, the ALC floor slab fixing hardware 2 is changed according to a change in floor plan or the like.
The position of the ALC floor slab 25 can be changed at any time by changing the mounting position of the ALC floor slab 25.
