Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a panel for the exterior wall of a reinforced building made of reinforced plastics as a base material.

BACKGROUND ART Light cellular concrete panels have been well known and widely used as exterior wall panels for buildings whose structural bones are reinforced steel. The light cellular concrete panel has the advantages of being non-combustible, has excellent weather resistance, and is lightweight, but on the other hand, it is hydrophilic and easily absorbs moisture, so it can easily absorb moisture depending on the external environment at the time of construction. It has been pointed out that when built into the exterior wall of a building, the moisture evaporates after construction, causing discoloration and deterioration of the exterior wall, and the biggest problem is that it generates moisture that is harmful to health.

Although the lightweight cellular concrete panels have major drawbacks in terms of the livability and aesthetics of buildings as mentioned above, there is no substitute for them in terms of non-combustibility and weather resistance, so there is no need to stop using them. The reality is that it is being used without benefit.

In particular, what is most strongly required for exterior wall panels, which are residential building materials, is noncombustibility, and the idea that they should be made of noncombustible concrete is well established.

Therefore, in the present invention, in order to break away from the fixed idea and eliminate the above-mentioned drawbacks, synthetic resin panels, which are completely unsuitable for use as building exterior wall panels due to their lack of flame resistance, are used as exterior walls. It was created with the intention of being applied as a panel,
In particular, reinforced plastics (hereinafter referred to as FRP) made of a composite material of glass fiber and polyester resin are lightweight, have unparalleled strength and weather resistance, and are also highly water resistant. Focusing on the fact that it has the optimum strength as a building exterior wall panel, as described below, we have created a material that has the maximum structural suitability required for construction and strength as a structural material for building exterior walls. It is an object of the present invention to provide an FRP building exterior wall panel which can solve the problem of lack of flame resistance, which is considered to be a drawback of FRP, and which can be suitably put to practical use as a building exterior wall panel in place of the above-mentioned light foam concrete panel.

Embodiments of the present invention will be described in detail below with reference to the drawings.

The building exterior wall panel according to the present invention is as described above.
The base material is FRP. As mentioned above, FRP is lightweight and has high strength, and is also excellent in waterproofness and airtightness.

As shown in the figure, the panel main body has an outer side plate 1, an inner side plate 2, and a surrounding side wall 3 formed of the above-mentioned FRP, and the three members 1, 2, and 3 are joined to the base material by the FRP structure forming each, and has an integral structure. FRP hollow panel 4
form.

The FRP hollow panel 4 has a rectangular shape and has a hollow structure inside.

The outer side plate 1, the inner side plate 2, and the surrounding side wall 3 are different from those in which each component is bonded with an adhesive after molding and hardening, and the base material structures are fused and hardened to form an integral structure.

Inside the internal cavity 5 of the above FRP hollow panel 4,
The reinforcement wall 6 made of the above-mentioned FRP is extended in a lattice shape,
Similarly, the outer side plate 1, the inner side plate 2, and the surrounding side wall 3 are connected to the base material to form an integral structure. The reinforcing wall 6
As a result, the inside of the internal cavity 5 is defined into a plurality of small cavities 7, and each of the small cavities 7 is filled with a soundproofing and heat insulating material 8 such as urethane which has a soundproofing and heat insulating effect on the panel. It is glued with barrel FRP.

For example, after coating glass fiber with polyester resin to a uniform thickness to form the inner side plate 2, and further forming the reinforcing wall 6 in the same manner, the soundproofing and heat insulating material 8 is placed inside the small cavity 7 while the FRP is not yet cured. Then, a composite wall of glass fiber and polyester resin is formed on the soundproof and heat insulating material 8 by the same method to form the outer side panel 1. As a result, the panel becomes an integral structure, and the soundproof and heat insulating material 8 is bonded to the inner wall of the small cavity 7.

A frame rib 9 serving as a core material is inserted into the peripheral side wall 3 of the FRP hollow panel 4 thus formed.
Similarly, a reinforcing bone 10 serving as a core material is inserted into the reinforcing wall 6 inside the FRP hollow panel 4.

The frame ribs 9 and reinforcing ribs 10 are inserted together with the formation of the peripheral side wall 3 and reinforcing wall 6, which are coated with polyester resin on glass fibers, and are integrally bonded within the walls 3 and 6 as the FRP hardens. This makes the panel a rigid structure.

The frame bones 9 and reinforcing bones 10 are made of plastic foam (ABS, PST,
Synthetic wood (e.g., "Eslon Neo Lumber FFU" manufactured by Sekisui Chemical Co., Ltd.) made by reinforcing a foam (foam, etc.) with long glass fibers is suitable.

Further, mineral particles such as silica sand or marble are applied to the outer surface of the outer side plate 1, and the outer surface is coated with a mineral particle layer 11 to impart heat resistance and fire resistance. The mineral particle layer 11 is formed by scattering particles 11' such as silica sand while the FRP, which is the base material of the outer side plate 1, is uncured and the polyester resin does not lose its viscosity. As shown in FIG. 6, the particles 11' form a layer 11 in a plurality of overlapping layers.

In addition, depending on the implementation, the above-mentioned inner side plate 2 and surrounding side wall 3
The outer surface of the mineral particle layer 11 may also be coated with the mineral particle layer 11.

Furthermore, a synthetic resin adhesive such as polyester resin is applied to the surface of the mineral particle layer 11 to form a continuous film 12 covering the mineral particle layer 11,
As shown in FIG. 6, the continuous coating 12 is formed by coating polyester resin, and the polyester resin and the outer side plate 1 are made of the same material to strengthen the bonding strength. The particles 11' are wrapped and held inside to protect the particles 11' from wind and rain, or the particles 11' are expanded, contracted, or cracked due to temperature differences to form an outer surface plate. When separated from 1, etc.
The particles 11' are firmly held inside the continuous coating 12 and prevented from falling off.

In FIG. 6, reference numeral 13 indicates the base material bonding interface between the outer side plate 1 and the soundproof and heat insulating material 8.

As mentioned above, lightweight foamed concrete panels, which are commonly used as external wall panels for high-rise buildings with steel frames, are hydrophilic and generate moisture that is harmful to health after construction, which may affect the habitability of the building. This has major disadvantages in terms of living space definition, such as spoiling the aesthetic appearance and causing discoloration and deterioration after construction.

The present invention eliminates the above-mentioned drawbacks of light cellular concrete panels, and makes it possible to apply synthetic resin panels as exterior wall panels, which had previously been considered completely unsuitable.

That is, the main body of the building exterior wall panel is formed of an FRP structure, frame ribs and reinforcing bones are inserted into the structure to serve as the core material of the structure, and the structure is filled with soundproofing and heat-insulating material. The present invention further provides an exterior wall panel having a structure in which the outer surface of the panel forming the outer surface of a building is coated with a layer of non-combustible mineral particles.

As mentioned above, the exterior wall panel of the present invention is made of FRP
By using FRP as a base material, we can provide building structural panels that satisfy the essential requirements for exterior wall panels, such as FRP's greatest advantages of excellent mechanical strength, durability, and weather resistance, as well as moisture blocking ability.

The FRP panel of the present invention is suitable for use as a structural material for building exterior walls as well as for improving livability, and generates moisture that is harmful to health, which was considered to be the biggest drawback of conventional light cellular concrete. , will not cause discoloration or deterioration of the exterior wall after construction,
On the other hand, we were able to solve the problem of lack of flame resistance, which is the most hindrance when applying FRP as an exterior wall panel.

The present invention eliminates the conventional fixed idea that exterior wall panels, which are a housing construction material, are made of non-combustible concrete, and makes it possible to put into practical use the above-mentioned building exterior wall panels that take full advantage of the qualities of FRP while eliminating its drawbacks. This made it possible to apply and utilize FRP panels as building structures.

Furthermore, the present invention makes it possible to reliably maintain the above-mentioned non-combustibility effect required for external wall panels made of FRP over a long period of time. That is, an exterior wall panel is provided in which a continuous coating of synthetic resin adhesive is formed on the surface of a mineral particle layer that imparts noncombustibility to the FRP panel.

The particles of the mineral particle layer that coats the outer surface of the panels forming the outer surface of the building are exposed to wind and rain and are directly subjected to severe temperature changes in summer and winter, etc. due to external conditions. When exposed to wind and rain, the particles deteriorate and fall off, making it impossible to maintain the above-mentioned non-combustible effect, and due to temperature differences, the particles repeatedly expand and contract, causing cracks, which promote the falling of the cracked part of the particles. , it becomes impossible to sufficiently maintain the above-mentioned nonflammability effect. However, the exterior wall panel of the present invention, as described above, forms a continuous film covering the surface of the mineral particle layer, and this continuous film is formed by applying a polyester resin, and this polyester resin film and the above-mentioned
The bond with the FRP structure is extremely strong, forming a state where the particles are wrapped and held inside. The retention effect of this coating prevents the particles from being exposed to the wind and rain, reliably preventing them from falling off due to deterioration, and even if the particles expand, contract, or even crack due to temperature differences, the particles will remain in the coating. It is firmly held inside the FRP panel and reliably prevents particles from falling out due to cracks, making it possible to reliably maintain the above-mentioned non-combustibility effect required for exterior wall panels for a longer period of time, making it possible to put FRP panels into practical use. Contribute greatly.

Furthermore, the building exterior wall panel of the present invention can improve the soundproofing and heat-insulating effect of the panel by using the soundproofing and heat-insulating material filled inside, and can also increase the thickness of the panel without increasing the weight of the panel.
By creating a composite structure of the soundproofing insulation material and the panel matrix, the weight of the entire panel can be reduced, and the weight of the panel required for high-rise buildings can be reduced as much as possible. In addition, the rigidity of the panel is increased by the nail-driveable frame rib and reinforcing bone inserted as a core material inside, and the occurrence of warping can be effectively prevented, and mounting holes that reach the frame rib are pre-drilled. This has the advantage that bolting and the like during construction can be easily performed.
