Description

[Detailed Description of the Invention] (Industrial Field of Application) This invention relates to a fiber-reinforced plastic structure used in unit housing and the like.

(Prior art) In recent years, Japanese Patent Publication No. 39-16542, Japanese Unexamined Patent Publication No. 53-1982
Unit housing as disclosed in Publication No. 14919 has achieved remarkable development due to its advantages such as shortening the construction period, improving productivity by standardizing the basic units of the structure, and reducing costs due to these.

In addition, there has been remarkable progress in the materials used for the structures used in the above-mentioned unit houses, and the mainstream of structural materials has ranged from traditional building materials such as wood and concrete to plastics, which have excellent durability and corrosion resistance. It is expanding.

Furthermore, recently, as disclosed in Japanese Patent Publication No. 43-11151, fiber-reinforced plastics whose mechanical strength has been improved by combining glass fibers and the like have come into use.

(Problem to be solved by the invention) However, in the conventional fiber-reinforced plastic structure described above, although the mechanical strength of each basic unit of the structure has improved, the connection structure between the basic units is not truss from a structural mechanics point of view. structure, there was still room for improvement from the perspective of the rigidity of the entire structure as a collection of basic units.

(Means for solving the problem) This invention was made to solve the above problem, and its gist is to provide a substantially rectangular floor panel made of fiber-reinforced plastic with a reinforced flat plate portion, and a reinforced and four pillar members made of fiber-reinforced plastic arranged with their rounded ends in contact with the four corners of the floor panel, and the floor panel and the pillar members have a plurality of bolts passing through the contact surfaces. The fiber-reinforced plastic structure is characterized by being tightened by.

(Function) Since the floor panels and column members, which are the basic units of the structure, are each made of fiber-reinforced plastic, the mechanical strength, corrosion resistance, weather resistance, durability, etc. of each basic unit are extremely high.

On the other hand, the reinforced flat plate part of the floor panel and the reinforced end of the column member come into contact with each other, and the floor panel and the column member are tightened by bolts that pass through the abutting surfaces, so the rigidity of the joint is increased. The connection structure of these basic units becomes a rigid frame structure in terms of structural mechanics, improving the rigidity of the entire structure as an assembly of basic units, eliminating the need for reinforcement such as braces and load-bearing walls, and improving the mechanical strength of the structure. Strength and freedom of floor plan when used as a building are improved.

(Embodiment) Hereinafter, an embodiment of this invention will be described based on the drawings of FIGS. 1 and 2.

In FIGS. 1 and 2, reference numeral 1 denotes a fiber-reinforced plastic structure, which in this embodiment is used in a housing unit.

The above structure 1 is a floor panel 10 as a basic unit.
and a column member 20 (column member).

The floor panel 10 is made of glass fiber reinforced plastic (hereinafter abbreviated as FRP), and includes a top plate 11 (flat plate portion) serving as a floor material, a side plate 12 extending downward from the periphery of the top plate 11; A bottom edge plate 13 extending inward from the lower edge of the side plate 12 and a predetermined number of ribs 14 extending across the opposing long side plate 12 as shown in FIG. 1 are integrally molded. It is something.
The four corners of the top plate 11 and the bottom edge plate 13 are thickened and reinforced, and four through holes 15 are provided in each corner.

The column member 20 has a rectangular cross section and has a two-layer structure, and has a foam layer 21 made of polyurethane resin or the like inside.
The outside thereof is covered with an FRP layer 22 of a predetermined thickness. The FRP layer 22a at both ends 23 in the longitudinal direction (vertical direction in the figure) of the column member 20 is made thicker and reinforced than the FRP layer 22 at other parts. Four screw holes 24 are formed along the longitudinal direction of the column member 20. Incidentally, for convenience of illustration, the upper end portion 23 of the column member 20 is omitted.

Each of the pillar members 20 is arranged such that the lower surface 25 (contact surface) of the reinforced end portion 23 is in contact with the four reinforced corners of the upper plate 11 of the floor panel 10.
It is placed perpendicular to the

Then, bolt 3 from the back side of the box-shaped frame 10.
0 is inserted into the through hole 15 and further screwed into the screw hole 24 of the column member 20, and the column member 20 is inserted into the floor panel 10.
It is tightened and fixed.

Note that a box-shaped frame 10 is provided at the upper end of the column member 20.
Something similar to this is tightened and fixed with bolts and becomes a unit room unit of a unit house.

In the above configuration, the floor panel 10 and each column member 20, which are the basic units of the structure 1, are each made of FRP, so the floor panel 10 and each column member 20 have mechanical strength, corrosion resistance, weather resistance, and durability. It has extremely excellent properties.

In addition, the connection structure between the floor panel 10 and the column member 20 is such that the reinforced top plate 11 and the reinforced end portion 23 are in contact with each other and are tightened and fixed with four bolts 30. The rigidity is improved, resulting in a rigid frame structure in terms of structural mechanics, and the rigidity of the entire structure 1 is significantly improved.

Therefore, the structure 1, that is, the unit house, exhibits extremely excellent mechanical strength, corrosion resistance, weather resistance, durability, etc. In addition, the floor panel 10 and the column members 20 have sufficient mechanical strength, eliminating the need for reinforcement of braces, load-bearing walls, etc., and improving the flexibility of the floor plan, such as openings.

This invention is not limited to the above-mentioned embodiments, and various embodiments are possible. For example, the floor panel is not limited to the one for the floor, but may be for the ceiling, and the flat plate portion may be formed only at the portion that comes into contact with the column member. Further, the column member is not limited to a column, but may be a beam.

Furthermore, the bolt may be embedded in the column member, the tip of the bolt may be made to protrude from the contact surface, and the nut may be tightened by penetrating the flat plate portion of the floor panel.

Furthermore, the reinforcing material used in fiber-reinforced plastics is not limited to glass fiber, but may also be carbon fiber or the like.

(Effects of the invention) As explained above, according to this invention, the floor panels and long members, which are the basic units of the structure, are each made of fiber-reinforced plastic. Extremely high strength, corrosion resistance, weather resistance, durability, etc.

On the other hand, the reinforced flat plate portion of the floor panel and the reinforced end portions of the column members are in contact with each other, and the four corners of the floor panel and the four column members are tightened by bolts that pass through the contact surfaces. As a result, the rigidity of the joint is improved, and the connecting structure of these basic units becomes a rigid frame structure in terms of structural mechanics, improving the rigidity of the entire structure as a collection of basic units, eliminating the need for reinforcement such as braces and load-bearing walls. Become.

Therefore, the mechanical strength of the structure as a whole,
Corrosion resistance, weather resistance, durability, etc. are improved.
