DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lattice floor structure used for forming a floor of a building.

[0002]

2. Description of the Related Art A conventional floor structure is disclosed, for example, in Japanese Patent Application No. Hei.
Patent No. 74526 describes a plurality of lattice materials 20.
And a plurality of support members 21 and a deck plate 22. As shown in FIGS. 6 and 7, the support member 21 is formed by alternately forming flat skirt portions 21a and chevron portions 21b.
The flat base 21a is fixed to the deck plate 22.
The lattice material 20 is formed by bending the upper chord material 20a and the lower chord material 20b into a bent material 2.
The lower chord member 20b is supported by the chevron portion of the support member 21 in an orthogonal state.

[0003]

As described above, the conventional floor structure has a complicated structure and is not easy to assemble even when assembled at a construction site, and is easy to carry into a construction site even when assembled at a factory. There was a problem that was not.

[0004] The present invention has been proposed to solve such problems of the prior art, and has as its object to provide a lattice floor structure which has a simple structure and is easy to assemble. .

[0005]

In order to achieve this object, a lattice floor structure according to the present invention is formed by bending a lattice member having a flat plate bent into a mountain-shaped cross section by bending the lower end edge of the mountain-shaped portion outward. The lattice material is placed on the deck plate through the skirt, and the lattice material is provided with a plurality of long holes for pouring concrete on the side surfaces of the chevron, and a hole for venting air at the top of the chevron. A support rod is fitted into the hole in a manner orthogonal to the longitudinal direction of the lattice material, and is erected on the top of the chevron of each lattice material arranged adjacent to the deck plate, and the support rod is connected to the chevron. This is a structure that is bound to the top of the chevron with a wire locked in a long hole.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view showing a lattice floor structure according to an embodiment of the present invention. FIG. 1 shows a side view of the lattice floor structure, FIG. 2 shows an enlarged side view, and FIG.
4A is a longitudinal sectional view, and FIG. 4 is a plan view. In these figures, the lattice structure includes a deck plate 1 and a lattice material 2. The deck plate 1 has a concave portion 3 below the lattice material, and two flat ridges 6 on which a skirt portion 5 of the lattice material 2 is placed project from a flat plate portion 4 on which the lattice material 2 is mounted. Have been. Also, hook-like portions 7, 7 for connection are provided at both end portions. The lattice member 2 is formed by bending a flat plate into a mountain shape in cross section, and forms a skirt portion 5 by horizontally projecting lower ends on both left and right sides in a horizontal direction.

A plurality of long holes 8 into which concrete is poured are formed in the side surface 2a of the lattice member 2. A support rod 9 is fitted into the top of the lattice member 2 and a plurality of holes 10 serving as air vents are formed in the lattice member 2.

In the lattice floor structure constructed as described above, the skirt portion 5 of the lattice material 2 is placed on the ridge 6 of the flat plate portion 4 of the deck plate 1 and welded. After that, the support rod 9 is passed in the front-rear direction to the hole 10 at the top of the lattice material 2 and the support rod 9 is bound by the wire 11 entangled with the left and right long holes 8. Thus, the lattice floor structure has a simple configuration and is very easy to assemble.

Next, a lattice structure according to another embodiment shown in FIG. 5 will be described. In this lattice structure, a ridge 12 on which the skirt portion 5 of the lattice material 2 is placed is projected from the flat plate portion 4 of the deck plate 1 in the front-rear direction, and the skirt of the lattice material 2 The height of the lattice member 2 from the deck plate 1 can be adjusted by shifting the mounting position of the part 5 in the front-rear direction as indicated by the arrow.

[0010]

According to the present invention, as described above, a lattice floor structure can be formed by placing and fixing a lattice material obtained by bending a flat plate into a mountain shape on a deck plate. The structure is very simple compared to the structure,
It can be easily assembled even at construction sites. In addition, there is an advantage that even when assembled in a factory, it can be easily carried into a construction site. In particular, by binding a support rod fitted into the top hole of the chevron of the lattice material to the top of the chevron with a wire through the long hole on the side surface of the chevron, each lattice material arranged adjacent to the deck plate is tied. The connection structure is extremely simple in operation, and the top hole and the side surface long hole can be provided at a low cost by simplifying the configuration by combining them with other functions.
