Abstract

PROBLEM TO BE SOLVED: To improve durability by inserting a metal plate having a peripheral folded back part in an approximately flat plate type panel body made of FRP panel, and integrating the metal plate and the panel body with each other. SOLUTION: A metal plate 21 with an upward folded back part 21a is clamped between an FRP surface layer 11a and and FRP reverse layer 12a for integration, thereby forming a flat part 1a for a floor part 1a. An engagement and placement piece 1b for positioning and fixing the flat part 1a to a floor joist or the like in a balcony structure body or the like is formed around the flat part 1a, and a drain gutter 1c is formed on one side of the flat part 1a. An FRP panel body 1 is thereby formed. As a result, bonding strength between FRP and the metal plate 21 increases, and the separation thereof does not take place easily. Furthermore, the flexural strength of the metal plate 21 increases, and the flat part 1a is reinforced. At the same time, load resistance increases.

1 is a schematic vertical sectional view showing the structure of an embodiment of the present invention. The panel body 1 includes a flat plate-shaped portion 1a that constitutes a floor surface portion, a mounting piece 1b that is formed around the flat plate-shaped portion 1a and that is positioned and fixed on a floor support bar or the like that is provided on a structure of a balcony, and a flat plate-shaped portion. The drain groove 1c is formed on one side of the portion 1a, and these are integrally formed by press-molding FRP.

Inside the flat plate-shaped portion 1a of the panel body 1,
A metal plate 21 having an area that covers almost the entire area of the flat plate portion 1a is sandwiched. That is, the flat plate-shaped portion 1a of the panel body 1 has a three-layer structure and the surface layer 11a made of FRP.
The metal plate 21 is sandwiched between the back surface layer 12a and the back surface layer 12a, and these are integrated with each other.

The metal plate 21 is, for example, a thin steel plate having a thickness of about 0.3 to 2 mm, and is folded upward at a height of 50 to 80% of the product thickness all around the circumference. The folded portion 21a is formed.

In this example, the panel body 1 has cross bars 31 having different heights on a floor support bar 30 supported by a balcony structure, as shown by a chain double-dashed line in the figure.
By being placed and fixed via the, the drainage groove 1c is laid with a slight inclination so that the drainage groove 1c side is lowered.

According to the above-described embodiment, since the folded portion 21a is formed around the metal plate 21, the FRP forming the panel body 1 also enters the inside of the folded portion 21a. Due to the anchor effect, the adhesive strength between the FRP of the panel body 1 and the metal plate 21 is increased, peeling hardly occurs, and at the same time, the folded portion 2
As a result of the bending strength of the metal plate 21 itself being increased by 1a, the flat plate-shaped portion 1a of the panel body 1 is sufficiently reinforced and exhibits excellent load resistance.

FIG. 2 is a schematic vertical sectional view showing the structure of another embodiment of the present invention. The feature of this embodiment is that a reinforcing member sandwiched in the flat plate-shaped portion 1a of the panel body 1 is replaced with a large number of through holes 22a instead of the metal plate 21 of the previous example.
Is used, and the metal plate 22 is used in which the upwardly folded portions 22b are formed around the respective through holes 22a. The through hole 22a of the metal plate 22 is 2 mm to 10 mm.
The folding height of the folding portion 22b can be set to about 50 mm to 50% of the product thickness as in the previous example, and the thickness of the metal plate 22 can be made equal to that in the previous example.

In this embodiment, the panel body 1
The FRP forming the inside of each through hole 22a simultaneously enters the inside of the folded portion 22b around the through hole 22a, and the adhesion strength between the FRP of the panel body 1 and the metal plate 22 is strong due to the anchor effect. Therefore, peeling is less likely to occur, and the presence of the folded portion 22b increases the bending strength of the metal plate 22 itself as in the previous example, and the flat plate portion 1a of the panel body 1 is in a sufficiently reinforced state. .

FIG. 3 is a schematic vertical sectional view showing the structure of still another embodiment of the present invention. The feature of this embodiment is that a metal folding plate 23 having a large number of grooves 23a formed in parallel with each other in a predetermined direction is used as a reinforcing member sandwiched in the flat plate-shaped portion 1a of the panel body 1. The thickness of the metal folded plate 23 is about the same as in the previous examples, and the width of the groove 23a is 3
The depth is about 0 to 50 mm and the depth is about 50 to 80% of the product thickness. The metal folded plate 23 contains a metal material called keystone used as a floor structure material in general construction.

In the embodiment of FIG. 3, the FRP forming the panel body 1 is inserted into the grooves 23a of the folded body 23 from the front and back sides, respectively.
Due to the anchor effect, the adhesive strength between the panel body 1 and the metal folding plate 23 is increased, and both of them are less likely to be peeled off, and the bending strength of the metal folding plate 23 is flat due to the presence of the multiple grooves 23a having an equal thickness. Since it is larger than the metal plate, the flat plate-shaped portion 1a of the panel body 1 is sufficiently reinforced and has excellent load resistance.

In each of the above embodiments, the back side of the panel body 1 is flat, and the panel body 1 is placed on an external structure such as a crossbar to provide an inclination. However, the present invention is not limited to this. Of course, the present invention is not limited to this, and it is of course possible to adopt a structure in which an appropriate leg portion is fixed to the back surface side of the panel body 1 and the leg portion gives an inclination.

Further, it goes without saying that the metal plates sandwiched inside the panel body 1 are not limited to steel plates, and may be other materials such as stainless steel plates.

[0022]

As described above, according to the present invention,
Inside the FRP panel body, a metal plate having bent portions formed around it, or a metal plate having a plurality of through holes formed and bent portions around the holes, respectively.
Alternatively, since the metal folded plates are sandwiched and integrated, the adhesive strength between the metal plate or folded plate as a reinforcing material and the FRP of the panel body is strong, and even if there is a difference in the thermal expansion coefficient between the two, it can be used for a long time. A floor panel that is difficult to peel off and has good durability can be obtained. Further, the folded portion of the metal plate or the groove of the metal folded plate contributes to an increase in the bending strength of the metal plate itself as a reinforcing material, so that the panel body is sufficiently reinforced and a floor panel excellent in load bearing is obtained.
