BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lightweight floor / ceiling structure such as a building or a temporary scaffold made of concrete or steel, and a girder material therefor.

[0002]

2. Description of the Related Art Conventionally, floors in concrete buildings
The ceiling part is arranged continuously with the outer wall or partition wall of the building frame, forms a formwork, is poured concrete, and is integrally molded. In addition, steel frames are constructed by installing pillars, beams, and cross beams, then arranging small beams and girder materials, attaching reinforcing materials to them, and attaching floor base plate materials, ceiling base materials, and board materials. It is.

[0003]

The conventional concrete floor / ceiling structure requires a long work period and man-hour because of the use of reinforcing and concrete formwork requiring skill. In addition, increasing the floor space after construction is a matter of integral molding, so it was difficult to increase the floor space. Even if the number of floors is increased, bar arrangement and formwork work may hinder long-term lives and activities. Furthermore, the construction cost is increased because the construction takes a long time and man-hours. Concrete is still inadequate in heat insulation, moisture proofing and soundproofing, and has a problem that the floor is heavy and shakes greatly due to an earthquake.

On the other hand, in a steel building, the way of passing beams and girders is complicated, and the construction of floors and ceilings is complicated and requires skill and days. The finished product was insufficient in heat insulation, moisture proof and sound proof.

[0005] The problem to be solved by the present invention is to solve these problems of the conventional concrete and steel structures, to simplify the work without skill, and to greatly shorten the construction period. It is an object of the present invention to provide a lightweight floor structure of a new concept that can be constructed, is lightweight, has excellent heat insulation, moisture proof, sound proof, and vibration proof properties, and can be easily adapted to an extension.

SUMMARY OF] In this invention, the opening surrounded by the cross beam member that is bridged skeleton wall or precursor walls of buildings, fully resistant Hibo over de or downwardly underfloor member upwardly through the spar Overhang. Stringer is underfloor member, intensity reinforcing to support the resistance Hibo over de. Then the hard foam resin was packed in a closed space surrounded by the underfloor member and the anti Hibo over de and the frame wall or the cross beam member,
And the outer periphery of the underfloor member and the anti Hibo over de and the frame wall or lateral beam member side integrally joined to construct the floor. In the present invention, the girder material
Via a horizontal connecting member provided opposite to the skeleton wall or cross beam member
In some cases, they may be suspended for a required time. Digits in this case
The material can be mounted efficiently and easily. Thus, in the present invention, the mounting of the spar-underfloor member-resisting Hibo over de, requires only bolted bis driving light work of such work quickly because reinforcement-formwork work is required Can be done. Moreover, by filling the space between the floor base material and the fire-resistant board with a hard foamed resin, sufficient strength against a lateral load can be obtained, and the load supporting force can be greatly improved.
In addition, the filled foamed resin enhances the heat insulating property, the soundproofing and the moistureproofing ability, and is excellent in these respects. By using a box-shaped girder filled with a rigid foam resin in a metal frame with a square cross section, the girder can be made a lightweight and high-strength girder, and also has heat insulation, soundproofing and moisture-proofing ability. Further enhance.

By providing a large number of elongated ribs on the side wall of the box-shaped girder of the present invention, the strength of the box body (strength against vertical load, lateral load and torsion) can be further increased.

The dimensions of the box-shaped girder member 5 used in this embodiment are an aluminum-plated iron plate having a thickness of 0.8 mm, a width of 40 mm, a height of 200 mm, a length of 3600-4500 mm, and a length of 10 mm. A large number of elongated ribs 9 having a width of 3 mm and a depth of 3 mm are provided on the side wall. Both ends of the box-shaped beam 5 are opened, and a U-shaped lid member 10 is inserted through the opening. Lid member 10
Pipes 14 are attached to the upper and lower portions of the middle of the U-shape, and the bolt insertion holes 16 of the box-shaped beam 5 communicate with the pipe 14. The box-shaped beam 5 is fixed to the horizontal connecting member 3 through the fittings 11 by inserting the bolts 12 through the bolt insertion holes 15 of the fittings 11 described later. The inside of the box-shaped beam member 5 is filled with a hard foamed resin 4 (eg, a urethane foam resin or a foamed phenol resin) in a factory or on site.

In this embodiment, a concrete frame of a building is used.
The horizontal connection member 3 of the C-shaped channel material is fixed to a required floor installation position of the wall with an anchor bolt or the like. This horizontal connecting member 3
