[Industrial applications]

 The present invention relates to a heat insulating and waterproofing plate for the back joint of a building, and the waterproofing of the roof, rooftop, balcony, outer wall, floors of parking lots, underpasses, pools, kitchens, bathrooms, entrances, etc. In doing so, it provides a back joint heat insulating and waterproof plate with excellent fire resistance and workability.

[0002]

[Prior art]

 Conventional waterproofing methods for buildings include sheet waterproofing method that spreads metal plates and sheets, asphalt waterproofing method that creates a waterproof layer using asphalt-based material, mortar waterproofing method that applies mortar, and synthetic resin waterproofing method. There is a waterproof coating method in which a material is applied to form a waterproof coating.

In any of the above methods, cracks are generated due to deterioration over time due to repeated expansion and contraction due to wind and rain or temperature changes. The occurrence of cracks causes water leakage and also forms a water channel, which is a factor of water leakage expansion. Moreover, these cracks could not be easily found and it was very difficult to repair the leaked water.

Further, since the conventional waterproofing method completely covers the surface to be waterproofed, peeling or floating may occur due to the influence of air, moisture, etc. generated from the surface to be waterproofed. Therefore, there is a problem that a degassing tower must be installed to degas and dehydrate.

[0005] Waterproofing work is largely dependent on the degree of skill of workers, and for unskilled workers, the difference between good work and bad work is significantly generated. In addition, since there is a lot of outdoor work, there is a problem that it is not possible to work in the rain, depending on the weather.

With respect to a building constructed in a fireproof area or the like, there are regulations on each part of the building, and the use of noncombustible materials is obligatory. There was a strong demand for a waterproof method that uses a non-combustible material instead of a waterproof coating layer made of a combustible material. In addition, since all joints for waterproofing work are external joints and are in direct contact with the outside, there were problems such as poor weather resistance and deterioration, and peeling due to scratches.

[0007]

[Problems to be solved by the device]

 The present invention has been made in order to solve such a problem. A non-combustible inorganic waterproof plate having six non-combustible waterproof coating layers produced at the factory is provided with water gradients and concave grooves in two directions around the surface. By using the back joint heat insulating and waterproof plate attached to the formed plastic foam plate material, the work at the site is extremely easy, and there is no concern about the quality of the finish due to the difference in the skill level of the workers, and the work can be performed immediately even after the rain. It is possible to do this by eliminating the need for waiting time, completely preventing water leakage due to cracks in the coating film, and forming the sealing material that fills the joints inside without exposing it to the outside. The purpose is to improve weather resistance and durability.

[0008]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, a back joint heat insulating and waterproof plate according to the present invention has a front surface and a back surface and an end portion of an inorganic flat plate on the surface of a plastic foam plate material having a water gradient on the back surface and grooves formed in two directions around the surface. The horizontal and vertical edges of the non-combustible inorganic waterproof board with the non-combustible waterproof coating layer formed on the six sides are positioned almost in the center of the concave groove formed in the plastic foam board material, and the other two sides are the horizontal and vertical directions. A heat-insulating waterproof plate is produced by adhering the end in the direction to the outside of the end of the plastic foam plate by about 30 to 50 mm. Sealing material is filled in the concave grooves in the two directions of this heat insulating waterproof plate, and it is attached to the outside of the plastic foam plate material of another heat insulating waterproof plate to be joined to this heat insulating waterproof plate about 30 to 50 mm outside. Position the end of the non-combustible inorganic waterproof board over the sealing material filling part of the groove and butt-join it.

By making the plastic foam plate material smaller in vertical and horizontal dimensions by about 5 to 15 mm than that of the non-combustible inorganic waterproof board, it is possible to make a relief when butt-joining the back joint heat insulating waterproof board.

[0010]

[Action]

 According to the above construction, a non-combustible inorganic waterproof plate having a water-proof coating layer formed on six sides of a rectangular inorganic flat plate having an arbitrary size is provided with a water gradient on the back surface and concave grooves are formed in two directions around the surface. By producing a back joint heat insulating and waterproofing board attached to a plastic foam board, even an inexperienced person can easily attach it in a matrix pattern by using a mounting fastener or an adhesive, and It is possible to form a waterproof coating layer by sealing with a sealing material using the gap as a back joint and joining on the upper surface of the sealing material.

Even if the waterproofing surface is rainy or immediately after raining, the water contained in the waterproofing surface or the permeated water due to rain will be attached to the waterproofing surface even if it is immediately constructed without time loss such as waiting for drying. The non-combustible inorganic waterproof plate, which is in contact with the back surface of the installed heat-insulating waterproof plate but is on the top surface of the heat-insulating waterproof plate, does not rise through the non-combustible inorganic waterproof plate because the back surface of the non-combustible inorganic waterproof plate has a waterproof coating layer. It gradually diffuses naturally from the inner surface of the.

According to the above, the waterproof surface of the building after waterproofing is completely protected from rainwater or precipitation by the noncombustible inorganic waterproof board having the waterproof coating layer on the six surfaces according to the present invention and the sealing material filled in the back joint. Can be shut off.

Since the waterproof coating layers on the back and end surfaces of the non-combustible inorganic waterproof board and the sealing material filled in the back joint are not exposed to the outside, it is possible to prevent performance deterioration due to ultraviolet rays, near infrared rays, etc. of sunlight. Yes, it has high weather resistance and does not easily change over time.

Since the upper surface of the sealing material is a noncombustible inorganic waterproof plate, the sealing material is not exposed to the outside. Therefore, the water resistance and weather resistance of the sealing material are improved, and deterioration of the sealing material can be prevented. When joining the non-combustible inorganic waterproof board, the sealing material is filled even in the minute gaps between the non-combustible inorganic waterproof boards, further improving the waterproof effect and durability of the sealing material.

The unit size of the non-combustible inorganic waterproof plate is such that handling is easy in construction, and since the unit coating area is small, cracks do not occur due to expansion and contraction due to temperature changes. Furthermore, it can flexibly follow expansion and contraction of the waterproof construction surface, and has a strong resistance to shocks such as heavy loads and earthquake loads. For this reason, the waterproof performance of the present invention is extremely durable with almost no change over time.

The surface of the back joint insulation and waterproof board according to the present invention is certified as a non-combustible material as a whole by applying a non-combustible waterproof material equivalent to the base material to an inorganic flat plate of non-combustible material, and each part of the building in the fireproof area or semi-fireproof area It is applicable to regulations that require the use of non-combustible materials for fire protection, and can be used for fireproof structures with the optimum material as a waterproof plate for buildings.

When a back joint heat insulating waterproof plate is attached to the waterproof surface of a building in an appropriate size in the form of a base mesh, in the case of a light building, it may be laid as it is using an adhesive, but the base is In the case of a steel frame, etc., it is generally fixed by a mounting metal fitting, and in the case of a flat concrete surface, etc., it is generally fixed with an adhesive, but the reverse case is also possible. If the base is made of wood, it should be attached with an adhesive or fixed with nails or screws to form a noncombustible waterproof coating layer on this surface.

When it is used as an outer wall and the building cannot be waterproofed from the outside due to the proximity of the building, the waterproofing can be completely performed from the inside of the building by fixing it with a mounting metal fitting. Since it is a back joint, only sealing with a sealing material is sufficient and it is not necessary to form a waterproof coating layer on the upper surface of the sealing material.

It is possible to preliminarily attach the mounting metal fittings to the back side of the inorganic flat plate, and then to stick the inorganic flat plate with the waterproof coating layer formed on the front and back surfaces and the end surface to the plastic foam plate material. . Therefore, the mounting fasteners can be freely attached.

As the inorganic flat plate, slag gypsum board, calcium silicate board, gypsum board, flexible board, asbestos cement perlite board, pulp cement board, ALC, PC board, block, ceramic board, GRC panel, extruded cement board, etc. are used. . The size of the rectangular inorganic plate is not particularly limited, but may be any size that can be easily handled and constructed, and the vertical and horizontal dimensions are both about 400 to 1000 mm and the thickness is preferably 6 to 30 mm.

The waterproof coating layer formed on the six surfaces of the inorganic flat plate is a waterproof layer using an asphalt-based material, a waterproof layer using a synthetic rubber or synthetic resin sheet, and a synthetic resin liquid material is a reinforcing cloth and mesh. It may be a waterproof layer formed by applying or spraying while sticking. However, it must be a non-combustible coating material equivalent to the base material that has been approved by the Ministry of Construction as a finish coating material for fire protection materials based on the Building Standards Act. By applying the non-combustible coating material equivalent to the base material to the six surfaces of the non-combustible inorganic flat plate, the non-combustible inorganic waterproof board can be formed.

The adhesive used here has elasticity, and an epoxy-modified rubber-based latex type, a rubber-based latex type, a vinyl acetate resin emulsion type, a vinyl co-polymer emulsion type, etc. can be used. Epoxy-modified rubber-based latex type is preferable.

The plastic foam plate material having a water gradient on the back surface and concave grooves formed in two directions around the front surface is not particularly limited as long as it can be extruded or bead-molded, and the type of plastic is not particularly limited, but polystyrene or vinyl chloride is more preferable. , Polyurethane, phenol, polyisocyanurate, etc. The water gradient to be applied to the back surface is about 1/100 to 1/200, and the direction of the gradient can be arbitrarily designed according to the shape of the waterproof construction surface such as the horizontal direction, the vertical direction, the diagonal direction of the plate material, or both directions from the center of the plate material.

The thickness of the plastic foam plate material is in the range of 10 to 50 mm, more preferably 15 to 40 mm. The concave groove formed in two directions around the surface is 10 to 30 mm wide from the end of the plastic foam plate to a depth of 5 to 15 mm.

The sealing material for sealing the joints between the inorganic flat plates having the waterproof coating formed on the six sides is a silicone-based sealing material 1-component type and / or 2-component type, modified silicone-based sealing material 1-component type and / or 2-component A two-component type of modified silicone-based sealing material is preferred. The modified silicone sealing material is more preferably a two-component type.

With the non-combustible inorganic waterproof plate attached to one side from the center of the groove of the plastic foam, the groove is sufficiently filled with the sealing material. Should be joined on the other side of the filled groove, the other non-combustible inorganic waterproof plate attached to the other back joint thermal insulation waterproof plate is placed and tightened, and the excess sealing material is abutted between the non-combustible inorganic waterproof plates. It fills even the small gaps at the joints and also flows out to some extent on the non-combustible inorganic waterproof board, but it is enough to wipe off this part.

That is, the dimension from the end face of the noncombustible inorganic waterproof plate to the end face of the plastic foam plate material is 40 mm.

The groove formed in the plastic foam plate material was filled with a modified silicone-based sealing material (“Hybon 2000” manufactured by Hitachi Chemical Polymer Co., Ltd.). On top of the filled sealing material, another non-combustible inorganic waterproof board, which is a back joint thermal insulation waterproof board, was placed, and a slightly overflowing caulking material was wiped on the butt joint between the non-combustible inorganic waterproof boards.
