Description

[Detailed Description of the Invention] (Industrial Application Field) This invention generally relates to a floor base material for steel frame construction, etc., and more specifically to a heat insulating floor base material dedicated to a trapezoidal wire corrugated iron plate such as a deck plate. is there.

(Prior Art) In recent years, floor base materials such as closed-cell synthetic resin foams have been used for floor construction such as steel frame construction and concrete construction using deck plates or keystone plates that are wavy iron plates bent up and down. .

In the past, however, a floor slab was created by placing reinforcing mortar or concrete on a trapezoidal wire corrugated iron plate such as a deck plate, and installing a floor slab on the floor slab. is there.

(Problems to be solved by the invention) Therefore, in the construction of the conventional heat insulating floor base material, since the slab of reinforced concrete is provided on the corrugated iron plate, the weight of the floor structure becomes large, and the pillars are accompanied with it. ，
Other steel-framed structures such as beams and girders will naturally have to be made larger and heavier, which naturally increases the construction cost and inevitably reduces work efficiency.

In addition, since a concrete slab is provided, it is humid and easily stuffy, and it is important that the floor is not uneven during the construction of the floor base material. There was also a problem in terms of stable construction.

(Means for Solving Problems) The present invention has been made to solve the above problems, and is configured as follows.

DETAILED DESCRIPTION OF THE INVENTION The heat insulating floor base material of the present invention will be described in detail below with reference to the accompanying drawings. 1 is a floor base material used for steel frame construction, concrete construction, etc. It is composed of the body. Therefore, in this invention, the above-mentioned floor base material 1
On the lower surface of the above, a plurality of recessed grooves 5 that can be fitted with the upper surface of the ladder-shaped corrugated iron plate 4 bent up and down such as a deck plate or a keystone plate are provided. The floor base material 1 is provided on the upper surface thereof with recessed grooves 2 into which joists 3 for nailing structural plywood and floor boards are fitted. Further, 4a is a bent convex portion of the corrugated iron plate 4, and 4b is a bent concave portion thereof.

(Usage state) The heat insulating floor base material of the present invention is one in which a plurality of recessed grooves 5 on the bottom surface of the floor base material 1 are closely fitted and mounted on the upper surface of the corrugated iron plate 4 such as a deck plate. In this case, an adhesive 6 such as resin mortar may be used as shown in FIG.

(Effect of the Invention) Since the heat insulation floor base material of the present invention is directly fitted on the corrugated iron plate 4 without the concrete slab being provided on the corrugated iron plate 4 such as the deck plate as in the conventional case, Compared with conventional construction, concrete slabs can be omitted, the floor structure can be made lighter, and naturally it can also contribute to the overall weight reduction of buildings such as steel columns and beams, which improves workability and work efficiency of construction. It is economical and economical because it is obtained.

Further, since no concrete slab is provided, there is no fear that the floor base material will get wet or damp, and especially the floor base material 1 is a deck bent up and down by fitting a plurality of recessed grooves 5 on the lower surface. Since it is fitted on the upper surface of the corrugated iron plate 4 such as a plate, the construction is easy and stable and reliable construction is guaranteed. In this invention, a joist 3 can be fitted in the recessed groove 2 on the upper surface of the floor base material 1 and nailed, for example, to structural plywood or floor board.
