Description

  The present invention relates to a fiber powder-containing inorganic system which is a composition with a natural plant-derived fiber or powder thereof or a synthetic fiber-derived fiber or powder thereof and an inorganic adhesive adhesive composition. An adhesive composition is formed on one or both sides of a building panel by an adhesion means and sufficiently dried, and then a cement-containing material is formed by the adhesion means, and the adhesion-forming body of the inorganic adhesive adhesive composition is cemented. It aims at provision of the cement adhesion body and its construction method characterized by using as an adhesion body.

Conventionally, buildings such as reinforced concrete structures have a mortar finish directly on the concrete frame that forms the exterior of the building when the exterior is tiled, for example, in an interior insulation method where insulation is applied inside the building. For example, in the external insulation method where insulation is applied to the outside of the building, foam insulation is used for the insulation, and after finishing the mortar directly with the lath, the exterior tile is attached. If, for example, a fiber-based heat insulating material is used as a heat insulating material for an outer heat insulating method, a heat insulating layer and a ventilation layer are formed between the concrete frame and the exterior material, so the distance between the concrete frame and the external material also increases. Because the weight of the exterior material and the shaking of the exterior surface due to an earthquake act as a bending moment on the hardware that attaches the exterior material, lightweight metal panels and ceramics Such as dry tile method has been known that was used as a base, such as Idengu.
In addition, cement-containing materials such as mortar and concrete are inexpensive and have good workability, and can be used as a base material for wall materials and flooring materials in general buildings, or by applying the cement-containing material to them. Although it is frequently used as a material, it is common to use a lath material in the middle of the wall material or the floor material and the cement-containing material in order to improve the adhesion between the material and the wall material or the floor material.

Therefore, in recent years, the following development examples have been seen in order to improve the above-described problems.
For example, for the purpose of providing a surface-treated steel sheet with excellent adhesion to a cement-containing material suitable for use in adhering to a cement-containing material such as mortar or concrete. It is used for the application of adhering to a cement-containing material, characterized in that it has a chromate film containing silica and an organic resin on the plated surface of the plated steel sheet with an adhesion amount of 5 to 120 mg / m ^{2 in} terms of Cr. Development examples such as surface-treated steel sheets can be seen. (Refer to Patent Registration 3219002)

  In addition, for example, the concrete mortar material adhered and applied as a decorative finish does not cause cracks, cracks, peeling, etc. due to aging, and it can be easily fixed and easily attached to the frame wall and can be handled easily. In order to solve this problem, as a means for solving this problem, in the wall base body made of foamed synthetic resin material that is fixedly attached to the wall of the housing, a filling groove is arranged on the outer surface to which the concrete mortar material is attached and applied after assembly. Are arranged in multiple rows or grids along the vertical or horizontal direction and obliquely inclined, and fixedly attached to the wall surface of the wall with the fixing member of the interior mounting means on the wall base body. Engaging grooves each having a substantially groove shape are adjacent to each of the end face surfaces in a cross-sectional manner in which adjacent wall base bodies are meshedly connected to each other. Intended for Judges provided in opposite directions to each other, wall base, for example cardboard in the body, the hard vinyl resins, metals such as iron, is developed example as to interior reinforcement member of the rigidity of the concrete mortar material or the like is observed. (Refer to JP 2001-20491 A)

  Furthermore, for example, compared with conventional composite building materials, the adhesion ability of the cement mortar material itself to the foamed synthetic resin material is improved, the occurrence of peeling, cracking, etc. is prevented, and the provision of an excellent strength is an issue. As a solution to this, a plurality of grooves are formed in parallel on at least one side of both sides of the foamed synthetic resin plate material layer, and a mesh-like shape corresponding to each groove size is formed inside each groove. After placing the lath material for groove and filling the cement mortar material so as to embed the lath material for groove, laminating the mesh surface lath material on one side and laminating the cement mortar material again By forming a composite building material in which the foamed synthetic resin plate material layer and the cement mortar layer are integrated, the groove is formed in a substantially dovetail shape, and the lath material for the groove is the deep part of the groove Composite building materials and their construction Production method is known. (Refer to JP-A-11-324216)

However, it has been pointed out that most of the lath materials used in the middle of the under-wall and under-floor materials and the cement-containing material have poor adhesion to the under- and under-wall materials.
In addition, the construction using the cement-containing material and the lath material according to the above-described prior art requires many steps, and thus requires a long time.
In addition, the construction using the cement-containing material and the base material according to the above-described prior art allows moisture in the cement-containing material to permeate into the base material and reduce the amount of water on each contact surface. Therefore, there has been a problem that it causes poor curing and a decrease in adhesion, and therefore the cement-containing material is easily peeled off after construction.

For example, regarding a development example such as a surface-treated steel sheet used for adhesion to a cement-containing material on a plated surface of a zinc-based or aluminum-based plated steel plate of Patent Registration 3219002, the plated surface of the plated steel plate It is pointed out that the need for a new surface treatment on the top requires new equipment and associated equipment costs, which leads to an increase in costs, making it difficult for companies with little power to introduce them.
Further, for example, in Japanese Patent Application Laid-Open No. 2001-20491, in a wall base body made of a foamed synthetic resin material that is fixedly attached to a wall surface of a casing, filling grooves are arranged on the outer surface to which concrete mortar material is attached and applied after assembly. As for the development example, there is a problem in the adhesion force of the concrete mortar material other than the filling groove on the outer surface because the labor is increased by the means of arranging the filling grooves on the outer surface to which the concrete mortar material is adhered and applied, leading to cost increase. It has been pointed out that there is.
Further, for example, in Japanese Patent Laid-Open No. 11-324216, a plurality of grooves are formed in parallel on at least one side of both front and back surfaces of the foamed synthetic resin plate material layer, and each groove is formed inside each groove. A mesh lath lath material corresponding to the size is arranged and filled with cement mortar so as to embed the lath lath material, and then a mesh lath lath material is stretched over one side. For the development example of forming a composite building material in which the foamed synthetic resin plate material layer and the cement mortar layer are integrated by laminating the cement mortar material again, the adhesion between the lath material itself and the foamed synthetic resin plate material It has been pointed out that the adhesion between the lath material itself and the cement mortar material is weak.
