Abstract

PURPOSE:To place and erect a structure member without reinforcing a joint part with a shape steel member. CONSTITUTION:In floor panels 3 in which steel plates 2 are fixed and integrated to the outer surface of panel frames 1 made of shape steel, tall-large size steel members 6 are used as shape steel members 4 which constitute a frame member located at a joint part where a structure member is placed and erected, so as to build the structure member without reinforcing the joint part of the floor panels 3, 3.

Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor panel suitable for forming the floor surface of basements and other underground structures.

Conventionally, when forming the floor surface of an underground structure, as shown in FIG.
A steel floor panel D consisting of a steel plate C fixed and integrated on the surface of
A desired number of panels are laid down, and adjacent floor panels D and D are fixed with bolts to form a floor surface.

0003

[Problems to be Solved by the Invention] In the above-mentioned conventional technology, as shown in FIG. Then, when constructing an underground structure by placing and tensioning a steel roof panel F on the upper surface, a structural member E is placed and erected on the joint between the floor panels D and D. If installed, floor panel D,
Since there is a risk that the joint part of D may buckle, a structural member E is placed on the joint part, fixed and reinforced, and the structural member E is placed on the joint part G.
It was necessary to mount and erect it.

The present invention has been made to solve the above-mentioned conventional problems, and provides a floor panel on which structural members can be placed and erected without reinforcing the joints with shaped steel. The challenge is to do so.

[0005]

[Means for Solving the Problems] In order to solve the above-mentioned problems, the present invention provides a floor panel formed by integrally fixing a steel plate to the surface of a panel frame made of shaped steel, in which structural members are mounted,
As a shaped steel that constitutes the frame material located at the joint part to be erected,
It is characterized by the use of large-sized steel, which is larger in height than the steel shapes used for other frame materials.

[0006]

[Embodiment] Fig. 1 and Fig. 2 show one embodiment of the floor panel of the present invention, in which a floor panel 3 is formed by fixing and integrating a steel plate 2 to the surface of a panel frame 1 made of shaped steel such as channel steel or angle steel. In this case, the steel shape 4 constituting the frame material located at the joint where structural members such as steel wall panels, pillar materials, stud materials, etc. are placed and erected has a height dimension larger than the shape steel 5 of other frame materials. This shows a steel floor panel 3 characterized in that it is made of a large steel 6.

FIGS. 3 to 6 show adjacent floor panels 3 and 3.
For example, the end of a large steel 6 is notched to make it the same height as the shaped steel 5 of another frame material, and the end plate 7 is welded to the notch, and Match 1
The large steels 6, 6 of the floor panels 3, 3 in the direction are brought into contact with each other, and the shaped steels 5, 5 of other frame materials of the adjacent floor panels 3, 3 in the other direction (direction perpendicular to the above-mentioned one direction) are brought into contact with each other. A joint box 8 made of a shaped steel piece is fitted between the notches of the large steel pieces 6, 6, 6, 6 of the adjacent floor panels 3, 3, 3, 3, and the large steel pieces are brought into contact with each other. 6, 6, 6, 6 end plate 7, 7, 7, 7 and joint box 8 and steel mold 5, 5,
5, 5 are fixed with bolts 9, 9,..., and in addition,
If necessary, large steel 6, 6, 6, 6 and junction box 8
An embodiment is shown in which a cover plate 10 made of a piece of steel plate is brought into contact with the upper surface of the floor panel 10, and is fixed with bolts 11, 11, . . . to join adjacent floor panels 3, 3 together.

In FIG. 7, a structural member 12 is placed on large steel plates 6, 6 at the joints of floor panels 3, 3, bolted and erected, and then a steel plate is placed on the upper surface of the structural member 12. An embodiment will be shown in which an underground structure can be constructed by placing roof panels 13 on the roof panels, bolting them, and stretching them.

[0009]

Effects of the Invention As explained above, the floor panel of the present invention is a floor panel formed by integrally fixing a steel plate to the surface of a panel frame made of shaped steel. As the shape steel that makes up the frame material used is a large steel whose height is larger than that of other frame materials,
The strength of the joint of the floor panel is significantly improved by the large steel located at the joint, and the structural member is placed on the joint,
When erected, there is no risk of buckling of the joints of the floor panels, and therefore structural members can be placed and erected without reinforcing the joints of the floor panels with shaped steel as in the past. .

[0010] In order to efficiently exhibit the effects of the present invention, for example, the steel frame for the frame material located at the joint where the structural members are placed and erected has a height of 250 mm,
A U-shaped sea bream with a horizontal piece size of 90 mm may be used, and a U-shaped steel with a height size of 150 mm and a horizontal piece size of 75 mm may be used as the other frame material.
