Abstract

PURPOSE:To facilitate an assembling work by fixing an angle latticed material where a fitting skirt part is formed on the lower end edge to a deck plate where projections are projected on a flat plate part. CONSTITUTION:A flat plate is bent to have an angle section to form a latticed material 2 where a fitting skirt part 5 bent outward is provided on the lower edge, and plural elongated holes 8 are bored in the side surface part 2a of the latticed material 2. Two projections 6 for placing the skirt part 5 of the latticed material 2 thereon are laterally projected on a flat plate part 4 where to install the latticed material 2 to form a deck plate 1 provided with connecting hook parts 7 on both side end parts thereof. The skirt part 5 of the latticed material 2 is placed and fixed on the projections 6 of the deck plate 1, and a support rod 9 is stretched between holes of the tops of the latticed material 2 and fixed by a wire. Thus, the constitution can be simplified so as to facilitate the work.

Description

Detailed Description of the Invention

[0001]

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

[0002]

2. Description of the Related Art A conventional floor structural material is, for example, Japanese Patent Application No. 2-2.
A plurality of lattice materials 20 as described in No. 74526.
And a plurality of support members 21 and a deck plate 22. As shown in FIGS. 6 and 7, the supporting member 21 is formed by alternately forming flat skirt portions 21a and chevron portions 21b,
The flat skirt 21a is fixed to the deck plate 22.
The lattice member 20 is composed of the upper chord member 20a and the lower chord member 20b and the bending member 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 structural material has a complicated structure and is not easy to assemble even when assembled at a construction site, and it is easy to carry it to a construction site even when assembled at a factory. There was a problem that it was not.

The present invention has been proposed in order to solve the problems of the prior art, and an object thereof is to provide a lattice floor structural material having a simple structure and easy to assemble. .

[0005]

In order to achieve this object, the lattice floor structural material according to the present invention is formed by bending a flat plate into a mountain shape in cross section, and forming a skirt for attachment by bending the lower end edge outward. In addition, the base of the lattice material is placed and fixed to the lattice material in which a plurality of long holes for pouring concrete into the side surface of the chevron portion are bored, and the flat portion serving as the attachment portion for the lattice material is placed. It is composed of a deck plate on which ridges are formed to project.

EXAMPLES Specific examples of the lattice floor structural material according to the present invention will be described in detail below with reference to the drawings. Fig. 1 shows a side view of the lattice floor structural material, Fig. 2 shows an enlarged side view, and Fig. 3 shows A.
-A longitudinal sectional view and FIG. 4 are plan views. In these figures, this lattice structure material is composed of a deck plate 1 and a lattice material 2. The deck plate 1 has a concave portion 3 below the lattice material, and two convex ridges 6 on which a skirt portion 5 of the lattice material 2 is placed are projected laterally on a flat plate portion 4 to which the lattice material 2 is attached. Has been done. Further, hook-shaped 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-shaped cross-section, and has lower end portions on both left and right sides horizontally projecting to form a skirt portion 5.

Further, a plurality of elongated holes 8 for pouring concrete are formed in the side surface portion 2a of the lattice material 2. At the top of the lattice material 2, a support rod 9 is fitted and a plurality of holes 10 also serving as air vents are provided.

In the lattice floor structural material thus constructed, 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 through the hole 10 at the top of the lattice 2 in the front-rear direction, and the support rod 9 is bound by the wire 11 entwined with the left and right elongated holes 8. Thus, this lattice floor structural material is simple in construction and very easy to assemble.

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

[0010]

As described above, according to the present invention, since the lattice floor structural material can be constructed by placing and fixing the lattice material in which the flat plate is bent into the mountain shape on the deck plate, the conventional floor can be constructed. It has a very simple structure compared to structural materials,
It can be easily assembled at the construction site. Further, even when assembled in a factory, there is an advantage that it can be easily carried into a construction site.
