Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a construction board material having fire resistance, heat insulation property, waterproof property, and water resistance, and a construction method thereof.

BACKGROUND OF THE INVENTION Various types of board materials for construction have been known that are fire resistant, heat insulating, waterproof, and water resistant, and are also in practical use, but many of them have drawbacks.

That is, for example, products made with a focus on fire resistance and heat insulation tend to be heavy and difficult to handle.
Furthermore, many of the products made with emphasis on waterproofness and water-resistance have problems with insulation, as well as problems with the waterproofness and water-resistance of the mounting parts and joints. hand,
These often cause problems during or after construction of houses, etc.

In addition, a certain degree of flexibility is required especially for construction on curved surfaces and uneven areas, but flexible construction boards that are lightweight, fire resistant, etc. It wasn't provided.

The present invention has been developed in view of the drawbacks of conventional construction board materials as described above.
To provide a construction board material that has fire resistance and heat insulation properties, is relatively lightweight and easy to remove, and does not have the conventional difficulty of waterproofing at joints, and a construction method for its attachment. The board was made of vinyl material such as polyethylene, has appropriate elasticity, and is made of lightweight closed foam. A fireproof layer made of woven inorganic material such as glass or asbestos is integrally provided on the surface of a heat insulating layer with a large number of voids to form the main body, and steps for joining are provided on both sides of the main body, which can be turned from front to back. It is made of polyethylene, etc. as a material, has appropriate elasticity, and is made of lightweight closed foam, and the back side has a continuous uneven surface in cross section that allows water to pass through. A fireproof layer made of an inorganic material such as glass or asbestos is woven on the surface of a heat insulating layer with many voids. The main body is formed integrally with a main body, and the main body is formed with connecting steps on both sides of the main body, and the front and back directions are changed. Attachment holes are formed through the main body at appropriate locations, and the thickness of the main body is inserted into the holes. A cup-shaped mounting member having a height equivalent to that of the main body and fitting into the mounting hole and having a flange formed on the upper edge for locking is fitted, and the back surface of the main body is attached to the wall surface etc. to which it is to be attached. A fixing member such as a bottom plate of the mounting hole member and a screw nail is driven into the wall surface, and a heat insulating material, a water stop agent, etc. are filled in the mounting member.

Next, an embodiment of the present invention will be explained with reference to the drawings.

1 is made of soft synthetic resin such as polyethylene and has appropriate elasticity. 2 is a heat insulating layer made of a lightweight closed foam material; 2 is a water passage groove formed on the back surface of the heat insulating layer 1 by forming a continuous uneven surface on the back surface; 3;
is a fireproof layer formed by weaving non-combustible inorganic materials such as glass fibers and asbestos into a suitable rectangular flat plate shape and laminated on the surface of the heat insulating layer 1 by heat fusion, etc. As described above, the main body of the construction board material of the present invention is formed. Form.

4. 4' are equal-sized joining steps formed on both sides of the main body in the width direction. Consists of plate materials for use.

Therefore, when constructing a building using the above-mentioned construction board of the present invention, a circular attachment hole 5 is provided in the part of the construction board to be fixed to a wall surface, etc. during the construction. A mounting member 6 made of metal or the like is fitted into the mounting hole 5 in a cup shape and has a flange 7 for locking the fireproof layer 3 on its upper edge, and the construction board material is pasted thereon. Apply to wall surface F etc.
The installation is completed by driving fixing tools such as nails 9 from the bottom plate 8 of the attachment member 6 into the wall surface, etc., and the attachment holes 5 provided in the construction board are usually kept in that state at the construction site. In addition, when driving fasteners such as nails 9, adhesive etc. should be used to ensure waterproofness, and
The attachment member 6 fitted into the attachment hole 5 has a force for press-fitting and fixing the hole-like material 10 obtained by punching the hole 50.
, or other insulation materials, water-stopping materials, etc.

Therefore, the plate material of the present invention has a fireproof layer exposed on the surface when it is installed made of an inorganic material, and a heat insulating layer made of closed foam on the back side. It is easy to handle because the plate material with the insulation layer can be made relatively lightweight, and since the voids for water passage are formed on the back side of the heat insulating layer, water etc. will not seep into the void side after construction. Even if there is a problem, the water can be guided downward, and since the joint part of the main body is formed into a stepped part and waterproofness is taken into consideration when joined, the main body is waterproof compared to conventional board materials of this type. Not only can it be easily constructed without impairing functionality, but it can also ensure sufficient waterproof functionality at the joints.

Also, does the board material of the present invention have a heat insulating layer? It is made of closed foam with appropriate elasticity, and the fireproof layer provided on its surface is also woven from an inorganic material, so it has appropriate flexibility as a whole and is suitable for curved surfaces and uneven areas. It can also be constructed without sacrificing the above advantages.

In addition, the water passage groove 2 in the above embodiment may be formed of a material different from the heat insulating layer 1 and applied to the back surface of the heat insulating layer 1, and the shape of the water passage groove 2 may also be a simple shape. The shape is not limited to the groove shape, and any shape may be used as long as it can ensure a void that can guide the water present on the back surface of the heat insulating layer 1.

It is also convenient if the recess formed by the attachment member 6 is filled with a rod-shaped body obtained when punching the attachment hole 5 after the work is applied to the wall surface of the plate material of the present invention.

The present invention is as described above, and a fire-resistant, heat-insulating, and waterproof building board material is formed with a simple structure, and during construction, devises are taken so that the above-mentioned performances are not impaired. It is extremely useful as a construction board material, especially a wall material, and is also useful as a board material to be attached to a surface of a concrete building where there is a risk of condensation.

Furthermore, during construction, the mounting member No. 7 has a height equal to the thickness of the main body, and is cup-shaped to fit into the mounting hole provided in the main body, and is formed with a 4Y shape on the upper edge for locking. It is possible to use a comparatively short force for the fixing device, such as by fitting it into the attachment hole and driving the bottom plate force into the fixing device such as a nail.
