Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for forming a plurality of architectural surface materials such as an outer wall panel and an inner wall panel between adjacent edges of an adjacent architectural surface material when constructing an inner wall or an outer wall. The present invention relates to a joint treatment method for a building surface material, in which an adhesive material is filled in and hardened to a joint, thereby sealing the joint and simultaneously joining adjacent building materials.

[0002]

2. Description of the Related Art Conventionally, when building an inner wall or an outer wall by adjoining a plurality of building surface materials such as an outer wall panel or an inner wall panel of a building, it is necessary to secure the ease of construction of the building surface material and to prevent the earthquake Joint between adjacent edges of adjacent building materials to ensure the effect of preventing destruction and damage due to rubbing between adjacent edges when the building is inclined due to etc., or for dimensional control of inner and outer walls etc. (Gap) is provided.

[0003] At this time, if the joint is left open, not only the appearance is bad, but also the sealing of the whole building cannot be ensured, so that the joint is generally closed.

FIG. 4A shows an example in which such joint processing is performed, wherein reference numerals 1 and 2 denote building materials composed of wooden boards adjacent to each other, and reference numerals 3 denote opposing edges of the building materials 1 and 2. Parts 1a, 2
a, 4 are the opposing edges 1a, 2
Substrates 5 such as pillars straddling between a and 5 are adhesive materials such as cement putty or plaster filled in joints 3.

[0005] The adhesive material 5 is cured by drying to bond the architectural surface materials 1 and 2 and the base 4, and at the same time, closes the joints 3 to improve the appearance and secure the hermeticity of the whole building. .

FIG. 4B shows another example in which joint processing is performed. Reference numerals 6 and 7 denote building surface materials made of gypsum board and steel plate adjacent to each other. Opposite edge 6
a, 7a formed by the joints a, 7a
A base 10 such as an iron pillar straddling between a and 7a is a closing material such as a rubber packing or a gasket inserted into the joint 8.

[0007] Since the closing material 10 connects the metal frames 6b, 7b fixed to the back surfaces of the building surface materials 6, 7 and the base 9 with the fixing members 6c, 7c such as screws, the joining effect is obtained. Those having a simple sealing effect without the need for a seal are used.

[0008]

By the way, in the joint treatment method for building surface materials constructed as described above, for example, when an adhesive material 5 such as cement putty or stucco is used, the adhesive material 5 is used. When dried and cured, volume shrinkage occurs, and with this volume shrinkage, there is a problem that a partial peeling occurs on the bonding surface, or so-called sink H which is recessed from the surface side to the back. Was.

[0009] Since the depth of the joint 3 increases as the depth of the joint 3 increases, the appearance is impaired. Therefore, in order to fill the sink H, the adhesive material 5 is added many times, or the fillet H is covered with an auxiliary tape. The next process is required, and the number of work steps and material costs increase.

Further, when a sealing material 10 such as a rubber packing or a gasket is used, not only does the material cost rise, but also aging tends to occur, so that there is a problem that repair and replacement work are required. Was.

Further, since the shape and size of the closing member 10 are determined in advance, it is difficult to cope with a dimensional error with respect to the width and depth of the joint 8.
7 requires labor and skill during the construction work.

According to the present invention, in order to solve the above-mentioned problem, it is possible to prevent the volumetric shrinkage when the adhesive material is dried and hardened and to prevent partial peeling or sink marks from occurring on the adhesive surface. It is an object of the present invention to provide a joint treatment method for a building surface material that can eliminate the need for abolition, repair and replacement work, thereby reducing material costs and work costs.

[0013]

In order to achieve the object, according to the first aspect of the present invention, a plurality of architectural face materials are arranged adjacent to each other, and each of the architectural face materials is opposed to each other. The gist of the present invention is to form a joint by separating the edges, fill the joint with an adhesive material that is unlikely to cause volume shrinkage during curing, and then cure the adhesive material.

The gist of the present invention is to mix a metal powder into the adhesive material and to cure the adhesive material by induction heating the metal powder.

According to a third aspect of the present invention, the bonding is performed by disposing a metal base straddling between opposing edges adjacent to each other on the back side of the architectural surface material, and inductively heating the metal base. The gist is to cure the material.

By the way, as the architectural surface material used in the present invention, a wood-based material, a cement-based material, an inorganic-based material, a metal-based material, or a composite material thereof is used.
As the type, there is used a building material of a large size to a small size including at least a flat surface such as a plywood, a particle board, a wood chip cement board, a gypsum board, a tile, a brick, a rock wool board, a metal siding board, and a metal folded board.

The adhesive material used in the present invention includes hot melt adhesives, silicone adhesives, epoxy adhesives, urethane adhesives, phenolic adhesives, melanin adhesives, etc. If the material does not easily cause volume shrinkage, an adhesive material is used in consideration of a good compatibility and a high bonding (adhesion) effect according to the architectural surface material and the base material used. More specifically, volumetric shrinkage can be suppressed by mixing an appropriate amount of metal powder with the inorganic filler.

At this time, when the joint is formed along the vertical direction of the building, it is needless to say that the joint has a viscosity that does not cause dripping before curing. Further, by adding a finishing aid, it is possible to promote the curability and improve the adhesiveness, etc., and by adding a flame retardant, it is possible to improve the fire resistance. In addition, volatile substances, preservatives, insect repellents, and the like, which are harmful to health due to inhalation by the occupants or construction personnel during respiration are excluded.

Further, the base material used in the present invention may be a wood-based material or a metal-based material. As described above, when a metal-based material is used, it is necessary to directly perform induction heating of the base material. Can be. Incidentally, a particularly preferred material is steel. Further, when the base cannot be induction-heated, induction heating becomes possible by blending a heating auxiliary material such as metal powder to be induction-heated into the adhesive material.

Induction heating generates eddy currents in a metal by electromagnetic induction and heats them as an induction heating element, and high frequency induction heating is particularly suitable. It is preferable that an induction heating / heating unit having an induction coil and a power supply and a control unit are separated from each other in a small size, thereby improving portability and workability. The shape of the induction coil is circular, oval, elliptical, rectangular, or the like, depending on the target of induction heating.
