ト３がらはみ出すようにする。Specifically, each upper chord member 5.5 is connected by a corrugated member 8, and both ends of each upper chord member 5.5 are supported by the upper sides of a pair of portal end fixing members 9, 9. In addition, each lower chord material 6.6
Both ends of the box girder are fixed inside a pair of gate-shaped end fixing members 9, 9, thereby forming a box girder with a gate-shaped cross section. In this case, the joining position of the upper chord member 5 and the corrugated member 8 is arranged between the joining position of the upper chord member 5 and the bending member 7. Note that all joints are fixed by welding. The spacer 2 has a chevron portion 10 with a flat top and a flat base portion 11.
...and are formed alternately. deck plate 3
By pressing a steel plate, a concave part and a convex part are arranged in parallel so as to correspond to the chevron part 10 and the flat base part 11 of the spacer 2, and the side ends are bent. The length of the deck plate 3 in the direction of the uneven portion is slightly shorter than the length of the box girder 1 (formed so that the gate-shaped end fixing member 9 protrudes from the deck plate 3).

ａを釘１４で固定する。Figure 5 shows an example of this floor structure material being constructed at a construction site. That is, the gate-shaped end fixing material 9 of the floor structure material is attached to the beam 12 and the inside of this portal-shaped end fixing material 9 is placed! The edge of the deck plate 3 is placed and welded. Then, a mesh-shaped wire mesh 15 is placed from above the lattice material 4 near the beam 12 to which the floor structure members are connected. It consists of an upper end distribution bar 17. In this case, the upper chord material 5 of the lattice material 4
Since the corrugated material 8 and the gate-shaped end fixing material 9 are fixed to the lower surface of the wire mesh 15, it is easy to place the wire mesh 15 (and the stability is high. Also, the lower end connecting bars 18 are bound to the lower chord material 6.6 with wire. This lower end connecting bar 18 is placed on the angular part IO of the spacer 2, but since the top of the angular part 1O is flattened, the lower end connecting bar 18 can be easily placed (Fig. 2). 2, there is an upper end distribution bar 1 placed on top of the upper chord member 5.
A lower end distribution bar 20 which is iaW is attached on top of the lower chord member 9 and the lower chord member 6. This lower end distribution bar 20 needs to be passed through the lattice material 4 at the construction site, so it may be installed in advance at the factory.In addition, if the casing 12 is a concrete formwork 13, as shown in No. 6 TXJ , the end 9 of the portal end fixing member 9
Fix a with nails 14.
