Abstract

PROBLEM TO BE SOLVED: To facilitate the manufacture by bending a steel plate in parallel to one edge thereof to form a number of isosceles triangles of the same size, and bonding the intersection of the equal two edges. SOLUTION: A rectangular steel plate is bent along a straight line parallel to, for example, its short edge to form a number of adjacent isosceles triangles of the same size, when seen from the long edge side, so that the intersections of two equal edges and the bottom edge are located on a straight line, and the intersection of the two equal edges is bonded by welding to constitute a panel body 1. A channel steel 2 is fitted to two long edge-side edges of the steel plate of the body 1 to nip the edges, and fixed by welding to enhance the bending strength of the body 1. A filler 3 such as general concrete, lightweight reinforced concrete, foamed concrete, or foamed plastic is filled in each hollow part of the isosceles triangles to enhance the rigidity, heat insulating property, and sound insulating property. According to this, a part of the steel plate functions as a lattice material. Further, since the intersection of the two equal edges of the isosceles triangles can be welded from the outside, the manufacture can be facilitated.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structural panel used as a floor plate or a wall of an open system in a building such as a steel frame structure, a reinforced concrete structure or a wall structure.

[0002]

2. Description of the Related Art Conventionally, as this type of structural panel,
It is known that two steel plates separated in parallel or a corrugated wide band steel are joined with a steel lattice material interposed therebetween (see Japanese Patent Application No. 9-19995).

[0003]

However, in the conventional structural panel, although the lattice material can be easily joined to one of the steel plates, the other steel plate or the like is used to join the lattice material to the other steel plate. Since it is necessary to provide a through-hole, there is a problem that manufacturing is complicated. Therefore, an object of the present invention is to provide a structural panel that can be easily manufactured.

[0004]

In order to solve the above-mentioned problems, a first structural panel according to the present invention comprises bending a steel plate along a straight line parallel to any one side thereof, and forming the steel sheet on a side perpendicular to any one side. A plurality of isosceles triangles of the same size as viewed from above are characterized in that the intersections of the two equal sides and the base of the adjacent ones are on a straight line, and the intersections of the two equal sides are joined. The second structural panel is characterized in that, in the first structural panel, a channel steel is fitted to edges of at least two sides perpendicular to any one side. The third structural panel is characterized in that, in the first or second panel, a hollow part having an end surface forming an isosceles triangle is filled with ordinary concrete, lightweight aggregate concrete, foamed concrete, or foamed plastic. I do.

In the first structural panel, a part of the steel plate functions as a lattice material, and intersections of two equal sides of an isosceles triangle are joined by welding from the outside. In the second structural panel, the same action as that of the first panel is obtained, and the bending strength is increased. Further, in the third structural panel, the same operation as that of the first or second panel is obtained, and rigidity (corresponding to earthquake resistance), heat insulation, sound insulation and the like are enhanced.

[0006] In the case of filling a hollow portion having an isosceles triangular end face with ordinary concrete or lightweight aggregate concrete, a plurality of through holes are formed in two equal sides of the isosceles triangle, that is, a portion functioning as a lattice material. It is preferable to provide concrete,
Filling of lightweight aggregate concrete etc. becomes easy. The through-hole may be formed by cutting and raising a V-shaped, U-shaped, semi-circular or the like. In this case,
Functions as an anchor for ordinary concrete and lightweight aggregate concrete.

Embodiments of the present invention will be described below with reference to the drawings. 1, 2, 3 and 4
FIG. 2 is a plan view, a front view, a side view, and an enlarged cross-sectional view taken along line IV-IV in FIG. 1 illustrating an example of the embodiment of the structural panel according to the present invention. In the figure, reference numeral 1 denotes a panel main body. This panel main body 1 is formed by bending a rectangular steel plate along a straight line parallel to the short side thereof, and forming a side perpendicular to the short side, that is, a large number of the same size as viewed from the long side. The isosceles triangles are adjacent to each other, so that the intersection and the base of the two equal sides of the isosceles triangle are on a straight line, in other words, one isosceles inverted between two erect isosceles triangles A triangle is formed, and intersections of two equal sides of an isosceles triangle are joined by welding or the like. Two sides corresponding to the long sides of the steel plate in the panel body 1 (left in FIG. 1,
In order to increase the bending strength of the panel body 1, the channel steel 2 is fitted into the edge of the right side) so as to hold the edge,
And it is fixed by welding or the like. Each hollow portion whose end face forms an isosceles triangle is filled with a filler 3 such as ordinary concrete, lightweight steel-frame concrete, foamed concrete, or foamed plastic in order to increase the rigidity, heat insulation, sound insulation and the like of the panel body 1. ing.

In order to manufacture the structural panel having the above structure,
A rectangular steel plate is bent along a straight line parallel to the short side by a press brake or the like, and the intersection and base of two equal sides of the many equal isosceles triangles of the same size viewed from the long side of the steel plate are equal. After being on a straight line, the intersections of two equal sides are joined by welding to obtain the panel body 1. Next, after the channel steel 2 is fitted to the edge of one side corresponding to the long side of the steel plate in the panel main body 1, the filling material 3 is filled into each hollow portion whose end surface forms an isosceles triangle. Then, the channel steel 2 is fitted to the edge of the remaining one side.

In the above-described embodiment, the case where the steel plate is bent along a straight line parallel to the short side has been described. However, the present invention is not limited to this. You may make it bend. or,
When filling the panel body 1 with the filler 3, the panel body 1
A hole may be provided in a portion functioning as a lattice material by punching or cutting and raising, so that the filling property is improved or the bonding property between the panel body 1 and the filling material 3 is improved. Further, the panel body 1 does not need to be fitted with the channel steel 3 and / or filled with the filler 3 as necessary.

[0010]

As described above, according to the first structural panel of the present invention, a part of the steel plate functions as a lattice material, and the joining of the intersections of two equal sides of an equal isosceles triangle is performed. Since it is performed by welding or the like from the outside, it can be easily manufactured. According to the second structural panel, the same operation and effect as those of the first panel can be obtained, and the bending strength is increased, so that the strength can be increased.
According to the third structural panel, the same operation and effect as those of the first or second panel can be obtained, and rigidity (corresponding to earthquake), heat insulation, sound insulation, and the like can be enhanced. The panel can have multiple functions.
