[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to a floor beam that supports a floor portion of a building or the like.

[0002]

2. Description of the Related Art As shown in FIG. 5, a floor beam of a conventional example is one in which floor panel mounting bolt insertion holes 103 are provided in both flanges 102 of a groove-shaped main body 101, and end plates 104 are attached at both ends. It was Ribs 106 were welded to the corners between the bottom surface of the web 105 of the groove-shaped body 101 and the end plates 104. In order to fix the floor panel (not shown) to the groove-shaped main body 101, the floor panel is arranged so that its end surface is along the flange 102 of the groove-shaped main body 101, and the bolt (not shown) inserted through the bolt insertion hole 103 is inserted. ), The end of the floor panel is bolted to the flange 102.

[0003]

However, it is necessary to suspend the floor panel with a crane or the like during the work of bolting the end portion of the floor panel to the flange 102, which makes the construction complicated. The purpose of this invention is to provide a floor beam that is easy to construct.

[0004]

The floor girder of the present invention is directed upwards.
On both flanges of the grooved body that opens at the
Lt through holes and attach end plates to both ends.
With the floor beam attached, a hat shape is formed on the lower surface of the web of the groove body.
Attach the top surface of the bracket and attach both flanges of this hat-shaped bracket.
It is characterized by protruding to both sides of the channel body.
It

[0005]

[Operation] According to the configuration of this invention, the top surface of the hat-shaped metal fitting is attached to the lower surface of the web of the groove-shaped main body that opens upward, and both flanges of the hat-shaped metal fitting are projected to both sides of the groove-shaped main body. Since the ends of the floor panel etc. are temporarily placed on both flanges of the hat-shaped metal fittings, both ends of the groove-shaped body are
It can be bolted to the floor panel mounting bolt insertion hole formed in the lunge .

DESCRIPTION OF THE PREFERRED EMBODIMENTS A floor beam according to an embodiment of the present invention will be described with reference to FIGS. As shown in FIG. 1, floor beams 1
No. 0 is provided with floor panel mounting bolt insertion holes 3 in both flanges 2 of the groove-shaped main body 1 opened upward and end plates 41, 42 mounted at both ends. The top surface 7 of the hat-shaped metal fitting 6 is attached to the lower surface of the web 5 of the groove-shaped main body 1 so that both flanges 8 of the hat-shaped metal fitting 6 are projected to both sides of the groove-shaped main body 1.

Ribs 4b are welded to the lower surface of the web 5 of the channel main body 1 and the corners between the end plates 41 and 42. The hat-shaped metal fitting 6 is formed by bending a steel plate so that the side surface has a hat shape. As shown in FIGS. 2 and 3, the channel main body 1 uses channel steel upward, and the frame member 9 a of the floor panel 9 is fixed by the bolts 12 inserted into the bolt insertion holes 3. .

The floor panel 9 has a frame member 9a and an upper surface 9b.
Is attached. The end plate 41 is a rectangular steel plate that closes the end opening of the groove-shaped main body 1, and is fixed to the column 11 by the bolt 13 inserted into the bolt insertion hole 4a. As shown in FIG. 4, the end plate 42 is fixed to the beam 14 supporting the wall panel 15 with bolts 13. Beams 16 are connected to both sides of the pillar 11.

When performing the construction, first, as shown in FIG. 4B, the end plates 41 and 42 are attached to the pillar 11 and the beam 1.
4 and bolts 13, respectively. As shown in FIG. 4C, the end portions of the pair of floor panels 9 are placed on the upper surfaces of both flanges 8 of the hat-shaped metal fitting 6. In this state, the frame 9a of the floor panel 9 is locked by the flanges 8. Next, the frame 9a of the floor panel 9 is attached to the flange 2 with bolts 12
Fix with.

As described above, since both ends of the floor panel 9 can be hooked by the both flanges 8 projecting on both sides of the groove-shaped main body 1, the floor panel 9 is craned while the bolt 12 is tightened. It is not necessary to hang it by the like and construction is easy.

[0011]

[Effect of the device] According to the structure of the device, the opening is upward.
Since the top surface of the hat-shaped metal fitting is attached to the lower surface of the web of the groove-shaped main body and both flanges of the hat-shaped metal fitting are projected to both sides of the groove-shaped main body, the end parts of the floor panel, etc. are both flanges of the hat-shaped metal fitting. Temporarily place it on the top of the groove body
It can be bolted to the floor panel mounting bolt insertion holes formed in both flanges . Therefore, during the work of fixing the floor panel and the like to both flanges of the groove-shaped main body, it is not necessary to suspend the floor panel and the like with a crane or the like, and the construction is easy.
