JPH09177218A - Method for lightweight construction of steel plate building floor and floor itself - Google Patents

Abstract

PROBLEM TO BE SOLVED: To reduce the weight of floor to a great extent by laying steel plates in line on a beam, welding fast to the steel material of beam and also welding the steel plates to one another, applying adhesive to the joints and the surfaces, and lining with a resin type coating or sheet and a floor material. SOLUTION: Steel plates 2 are laid in line upon a beam 1 of a building and welded by a welding 3 to the steel material of the beam 1. Also the steel plates 2 are welded together by a welding 4. A concrete series bonding agent 5 is applied to the joints of steel plates and their surfaces, and the resultant is lined with a resin type coating or sheet and a commercially available floor material 6 which may appear in different types. This permits reducing the floor weight to a great extent, while a strength to the same degree as a concrete floor finish with built-in reinforcing bars and a satisfactory touch sense are secured.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION When a floor of each floor of a building is to be constructed, the weight of the entire building is reduced by the construction by this method, and the weight of the foundation and the skeleton is reduced.

[0002]

2. Description of the Related Art Conventionally, in order to make a floor sticky, corrugated steel plate deck plates and the like have been constructed by laying reinforcing bars in a mesh shape and laying concrete for about 50 to 100 mm. See (Fig. 1)

[0003]

However, this has the following drawbacks. (B) Each floor of the building is heavy, and for that reason, it was necessary to make the foundation and the skeleton of the building a certain strength. (B) In the case of concrete floor, it was easy to crack. In rainy weather, it was necessary to consider the climatic conditions such as the inability to place concrete and the influence of the outside temperature.

[0004]

[Means for solving the problem]

(A) A steel plate (2) is laid on the beam (1) of the building, and each is welded and fixed (3) (4). A concrete adhesive (5) is applied to the seam and the surface of the joint 3 to 4 mm. (B) Since the coating thickness is thin, the weight can be reduced, and the floor weight of 1 m ² unit can be reduced to about 1/4 when the floor is constructed by the conventional construction method. (C) There is no cracking after floor construction, and it can be finished with the same feel as the conventional concrete construction method. (D) The same strength as a conventional concrete floor can be secured.

[0005]

BEST MODE FOR CARRYING OUT THE INVENTION By applying a concrete adhesive (5) and a resin paint (6) on a steel plate (2), the weight can be reduced to 1/4 as compared with the conventional floor construction.

[0006]

EXAMPLE A steel plate is laid on a beam made of reinforced concrete or a beam made of steel frame, and each is welded and fixed to the upper end surface of the beam. A concrete adhesive is applied to the seams and surfaces of the steel plates to a thickness of about 3 to 4 mm to evenly coat the seams of the steel plates so as to eliminate the irregularities generated at the seams. In addition, depending on the application, finish with resin-based hard paints / soft paints and PVC flooring, or general flooring.

[0007]

EFFECT OF THE INVENTION By welding the steel plate and the beam portion respectively,
By giving the floor strength and evenly applying the surface with a concrete adhesive, it is possible to obtain the same strength and feel as the concrete floor finish with built-in floor reinforcement,
The weight of the floor could be reduced significantly. By reducing the weight of the conventional floor by about 1/4, the building frame can be made thinner and lighter, and the total weight of the structure is also lighter, which is necessary for the foundation as well as in the past. It is about half of the cross-sectional area. As a result, the construction cost can be reduced by about 20 to 30%.
It should be noted that, compared to conventional concrete floor construction, it can be finished without being affected by weather conditions, and it also compensates for weaknesses such as cracks due to expansion and contraction that occur when concrete is solid, and yet concrete It has achieved labor saving in all without losing the feel of the floor.
