DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a deck plate beam fixing bracket, and more particularly to a deck plate beam fixing bracket capable of preventing the deck plate from coming off due to bending.

[0002]

2. Description of the Related Art A composite slab used as a floor plate of a building comprises a deck plate and concrete cast on the deck plate to a predetermined thickness. Composite slabs are constructed by placing the deck plate horizontally between beams and securing it, then casting concrete onto the deck plate.

[0003] The composite slab deck plate used for the composite slab having such a structure functions as a formwork at the time of casting concrete, and after hardening of the poured concrete, is integrated with the concrete and the strength of the composite slab. And a function as a reinforcing material to maintain high strength against bending moment acting on the composite slab.

[0004] The spacing between the beams on which the composite slab is mounted and fixed is usually between 3.0 and 3.4 m. The beam spacing can be further expanded in terms of the rigidity of the composite slab, but as described above, the composite slab is obtained by fixing the deck plate between beams and then casting concrete on the deck plate. Since the structure is constructed, unless the sectional rigidity of the deck plate itself is increased, there is a possibility that the deck plate may be bent due to the weight of the concrete at the time of placing the concrete, causing cracks in the concrete.

[0005] Therefore, various devices have been devised to increase the sectional rigidity of the composite slab deck plate. As one example, Japanese Utility Model Laid-Open No. 4-94009 discloses a pair of grooves 1A between adjacent peaks of a deck plate 1 as shown in FIG.
A method is disclosed in which a fixing member 2 is fitted into a slab, and a beam member 3 made of a reinforcing bar is arranged on the valley of the deck plate 1 by the fixing member 2. As shown in FIG. 10, the fixing bracket 2 is formed by bending an end of a flat steel plate bent in a mountain shape inward. Hereinafter, this fixing bracket 2
Is referred to as conventional technology.

In order to arrange the beam 3 on the valley of the deck plate 1 according to the prior art, the beam 3 is welded over the tops of the plurality of fixing brackets 2 and the adjacent peaks of the deck plate 1 are welded. The fitting 2 is fitted into the pair of grooves 1A formed by using the elastic force.

[0007]

However, the above-mentioned prior art has the following problems. That is,
Attachment of the fixture 2 to the deck plate 1 is performed by using the fixture 2
The width of the fixture 2 is reduced against the elastic force of
This is performed by fitting the end of the fixing bracket 2 into the groove 1A of the deck plate 1. The elastic force of the fixture 2 is
When this is fitted into the groove 1A of the deck plate 1,
It is not large enough to elastically deform the deck plate 1. Therefore, if the deck plate 1 is largely bent, for example, when an operator rides on the deck plate 1 during the operation, there is a possibility that the fixture 2 may come off from the groove 1A of the deck plate 1.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a fixing member for a beam material which is not easily detached even when the deck plate 1 is bent.

[0009]

According to the present invention, there is provided a beam fixing bracket for arranging a beam for enhancing a sectional rigidity of a deck plate for a floor plate on a valley of the deck plate. A leg fitted into a pair of grooves between adjacent ridges, and a beam fixing plate horizontally rotatably attached to the top of the leg, and an end of the leg is The leg is bent with respect to a vertical plane passing through a central axis, a distance between the ends of the legs is wider than a distance between the pair of grooves of the deck plate, and the elastic force of the legs is such that the legs have the grooves. It is characterized in that it has sufficient strength to elastically deform the deck plate when it is fitted to the deck plate.

[0010]

[Function] By making the elastic force of the leg portion larger than the elastic force of the deck plate, the leg portion does not easily come off the groove of the deck plate even if the deck plate is bent. The end of the leg can be easily fitted into the groove of the deck plate with a small force by rotating the leg.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is an exploded perspective view of an embodiment of the present invention.

FIG. 1 is a perspective view showing an embodiment of a deck plate beam fixing bracket of the present invention, and FIG. 2 is a plan view showing a state in which the deck plate beam fixing bracket of the present invention is mounted on a deck plate. FIGS. 3 and 4 are front views showing the mounting state of the deck plate beam fixing bracket of the present invention on the deck plate, and FIG. 4 shows the state in which the beam member is fixed to the deck plate beam fixing bracket of the present invention. Side view, FIG. 5 showing
FIG. 2 is a plan view showing a state in which the beam is fixed to the deck plate beam fixing bracket of the present invention.

The deck plate beam fixing bracket 4 of the present invention comprises a pair of grooves 1 between adjacent peaks of the deck plate 1.
It comprises an inverted U-shaped leg 5 fitted into A, and a beam fixing plate 6 attached to the top of the leg 5 so as to be horizontally rotatable. The ends 5A of the legs 5 are bent at substantially right angles in directions opposite to each other with respect to a vertical plane passing through the central axis of the legs 5. The elastic force of the leg 5 is larger than the elastic force of the deck plate 1. The beam fixing plate 6 is mounted on a substrate 7 fixed to the top of the leg 5 by a hinge 8 so as to be horizontally rotatable. Note that the beam fixing plate 6 may be directly rotatably attached to the top of the leg 5 without fixing the substrate 7 to the top of the leg 5.

In order to arrange the beam 9 made of a reinforcing bar on the deck plate 1 with the deck plate beam fixing bracket 4 of the present invention thus configured, as shown in FIG. 4 and FIG. A beam fixing plate 6 of a plurality of fixing brackets 4
A beam member 9 having a truss structure is fixed thereover by welding, caulking, or the like, and is disposed at a valley of the deck plate 1. Then, as shown in FIG. 2, the leg 5 of each fixing bracket 4 is rotated in the two-dot chain line direction in the drawing, that is, in the direction opposite to the bending direction of the end 5A, and the end 5A of the leg 5 is rotated. Fit into the groove 1A of the deck plate 1. After the legs 5 of the fixing fitting 4 are rotated and fitted into the grooves 1A of the deck plate 1, the beam 9 may be fixed to the beam fixing plate 6 of the fixing fitting 4 in a similar manner. In addition, the beam 9 may be any one of a single reinforcing bar, an H-shaped steel, a lightweight steel bar, and a steel pipe, in addition to the reinforcing bar having the truss structure.

The rotation of the leg 5 is achieved by the fact that the beam fixing plate 6 is rotatably mounted on the substrate 7,
Is rotated in the direction opposite to the direction in which the end 5A is bent, so that it can be performed smoothly. As described above, since the fitting of the leg 5 into the groove 1A is performed by a rotation operation, the end 5A of the leg 5 can be easily inserted into the groove 1A with a small force even if the elastic force of the leg 5 is large. Can be fitted into Moreover, since the elastic force of the leg 5 is larger than the elastic force of the deck plate 1, the leg 5 is fitted into the groove 1A,
The deck plate 1 is elastically deformed and fixes the leg 5. In this way, when the fixing bracket 4 is attached, the worker can get on the deck plate
Even if a bending force acts on the deck plate 1, there is no possibility that the fixture 4 already attached to the deck plate 1 comes off the groove 1 </ b> A of the deck plate 1.

FIGS. 6 to 8 show another embodiment of the fixture according to the present invention. Each of these fixing brackets has a leg 5
Is different from the fixture of FIG. That is, the fixing bracket of FIG. 6 has a plate-like leg 5 formed in a box shape.
Is fixed to the end 5A of the inverted U-shaped leg 5 once.
After being bent outward at right angles and then bent at right angles in opposite directions, the fixture of FIG. 8 is formed by forming the end 5A of the inverted U-shaped leg 5 into a ring shape.

[0017]

As described above, according to the present invention, by making the elastic force of the leg portion larger than the elastic force of the deck plate, the leg portion comes off the groove of the deck plate even if the deck plate is bent. Can be prevented. In addition, since the fitting of the end of the leg into the groove of the deck plate can be performed by rotating the leg, a useful effect that the end can be fitted with a small force is provided.
