Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a structural panel used as a floor board or wall body of an open system in a building such as a steel frame structure, a reinforced concrete structure, or a wall structure.
[0002]
[Prior art]
Conventionally, as this type of structural panel, one obtained by joining two steel plates separated in parallel or corrugated wide band steel with a steel lattice material interposed therebetween is known (Japanese Patent No. 9-19995). Issue).
[0003]
[Problems to be solved by the invention]
However, although the conventional structural panel can easily join the lattice material to one steel plate or the like, it is necessary to provide a through hole in the other steel plate or the like in order to join the other steel plate or the lattice material. Therefore, 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]
[Means for Solving the Problems]
In order to solve the above-mentioned problem, the first structural panel of the present invention is formed by bending a steel plate along a straight line parallel to any one side, and having a large number of the same size when viewed from a side perpendicular to any one side. It is characterized in that an isosceles triangle adjacent to each other is such that an intersection of two equal sides and a base are on a straight line, and an intersection of two equal sides is joined.
The second structural panel is characterized in that, in the first panel, channel steel is fitted to the edges of at least two sides perpendicular to any one side.
The third structural panel is characterized in that, in the first or second structure, a hollow part having an isosceles triangular end face is filled with ordinary concrete, lightweight aggregate concrete, foamed concrete, or foamed plastic. To do.
[0005]
In the first structural panel, a part of the steel sheet functions as a lattice material, and joining of intersections of two sides having equal isosceles triangles is performed by welding from the outside or the like.
In the second structural panel, the same effect as that of the first panel is obtained, and the bending strength is increased.
Moreover, in the third structural panel, the same action as that of the first or second panel can be obtained, and the rigidity (corresponding to earthquake resistance), heat insulation, sound insulation and the like can be improved.
[0006]
When filling ordinary hollow or lightweight aggregate concrete into a hollow part whose end face forms an isosceles triangle, it is necessary to provide a plurality of through holes in the two sides where the isosceles triangle is equal, i.e., the part functioning as a lattice material. Desirably, this makes it easy to fill ordinary concrete, lightweight aggregate concrete, and the like.
The through hole may be formed by cutting and raising a V shape, a U shape, a semicircular shape, or the like. In this case, the cut and raised pieces function as anchors for ordinary concrete, lightweight aggregate concrete, and the like.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
1, 2, 3, and 4 are a plan view, a front view, a side view, and an enlarged sectional view taken along line IV-IV in FIG. 1, showing an example of an embodiment of a structural panel according to the present invention. .
In the figure, reference numeral 1 denotes a panel body. This panel body 1 is formed by bending a rectangular steel plate along a straight line parallel to its short side, and having a plurality of the same size as viewed from the side perpendicular to the short side, that is, the long side. The isosceles triangles are adjacent to each other so that the intersection and base of two equal sides of the isosceles triangle are on a straight line, in other words, one isosceles inverted between two upright isosceles triangles It is configured such that there is a triangle and the intersection of two equal sides of the isosceles triangle is joined by welding or the like.
In order to increase the bending strength of the panel body 1 at the edges of the two sides (left and right sides in FIG. 1) corresponding to the long side of the steel plate in the panel body 1, the grooved steel 2 is held between the edges. And is fixed by welding or the like.
Each hollow portion having an isosceles triangle is filled with a filler 3 such as ordinary concrete, lightweight steel concrete, foamed concrete, or foamed plastic in order to increase the rigidity, heat insulation, sound insulation, etc. of the panel body 1. ing.
[0008]
To manufacture a structural panel with the above configuration, a rectangular steel plate is bent along a straight line parallel to the short side by a press brake or the like, and a number of isosceles triangles of the same size are adjacent to each other when viewed from the long side of the steel plate. After making the intersection of the two sides which are equal to each other and the bottom side be on the straight line, the intersection of the two sides which are equal is joined by welding to obtain the panel body 1.
Next, after fitting the grooved steel 2 to the edge of one side corresponding to the long side of the steel plate in the panel main body 1, the filler 3 is filled into each hollow part whose end face forms an isosceles triangle, and thereafter The grooved steel 2 is fitted to the edge of the remaining one side.
[0009]
In the above-described embodiment, the description has been given of the case in which the steel sheet is bent along a straight line parallel to the short side. However, the present invention is not limited to this, and the steel plate is bent along the straight line parallel to the long side. It may be.
In addition, when filling the panel body 1 with the filler 3, through holes are formed in the portion of the panel body 1 that functions as a lattice material by punching or cutting to enhance the filling property, or the panel body 1 and the filler 3 You may make it improve connectivity.
Further, the panel main body 1 may not be fitted with the grooved steel 3 and / or filled with the filler 3 as necessary.
[0010]
【The invention's effect】
As described above, according to the first structural panel of the present invention, a part of the steel sheet functions as a lattice material, and joining of intersections of equal two sides of equal isosceles triangles is welding from the outside. Therefore, the manufacturing can be easily performed.
According to the second structural panel, the same effect as that of the first panel can be obtained, and the bending strength can be increased, so that the strength can be increased.
Moreover, according to the third structural panel, the same effects as those of the first or second one can be obtained, and the rigidity (earthquake resistance), heat insulation, sound insulation, etc. can be improved. The panel can have multiple functions.
