JPH09209542A - Finishing substrate material for wall face - Google Patents

Abstract

PROBLEM TO BE SOLVED: To improve workability by sticking a granular inorganic material to a plate face via a synthetic resin adhesive. SOLUTION: A flat plate 1 made of a veneer board, a sizing board, or an FRP board and having a desired shape such as a rectangular shape or a square shape is used. An adhesive 2 made of an epoxy resin is applied over the whole one side face of the flat plate 1. A granular inorganic material 3 such as sand or silica sand is stuck to the upper face of the adhesive 2. This substrate material is fitted to the wall face portion of a building, e.g. fitted to sash bars, and mortar coating is applied on the granular inorganic material 3. Cement mortar coating can be directly applied without conducting the substrate process to stick the granular material on the surface after the substrate material is fitted to the building.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a finishing base material used for indoor and outdoor wall surfaces, and more specifically, for finishing used as a base on the inside of an outer wall such as a tile for decorating the surface of the wall surface. It relates to the base material.

[0002]

2. Description of the Related Art A wall surface of a building is composed of an inner wall, and a finishing base used for finishing the outer wall on the inner side of the outer wall is roughly classified into two types, a wet construction method and a dry construction method. . In the wet method, a through plate is provided on a wall portion provided between columns and the like, a wire net is stretched over the through plate, and mortar is applied to the outer surface of the wire net to form a base. An outer wall material such as a tile is attached to the outside through a mortar to form a wall.

In the dry method, an asbestos board or a gypsum board is attached to a wall portion of a building, and an outer wall material is attached to the asbestos board or the like by an emulsion type adhesive to form a wall surface.

However, since the dry method uses an emulsifying type adhesive as an adhesive, when used as a wall surface of an outdoor building, the adhesive absorbs moisture such as rainwater and re-emulsifies the adhesive to form an outer wall material. However, there was a problem of being separated from the base material.

In order to solve the above-mentioned problems, a method has recently been used in which an epoxy resin having water resistance is used as an adhesive for adhering a base material and an outer wall material so that the outer wall is not peeled off even when used outdoors. Proposed.

[0006]

However, since the epoxy resin prepared in the factory is used by being transported to the construction site, if the mixing time of the epoxy resin does not match the usage time, the epoxy resin However, there is a problem in that the epoxy resin is hardened and an expensive epoxy resin cannot be used, resulting in a high cost.

Therefore, according to the present invention, a granular material is preliminarily adhered to a base material substrate through an epoxy resin having high water resistance, and the granular material is transported to a construction site and attached as a base material between pillars, thereby reducing the cost. An object is to provide a base material for finishing which can improve workability.

[0008]

In order to achieve the above object, the invention according to claim 1 of the present invention is formed by adhering a granular inorganic substance on a plate surface with a synthetic resin adhesive interposed. .

The invention according to claim 2 of the present invention is characterized in that the synthetic resin adhesive of the invention according to claim 1 comprises an epoxy adhesive.

[0010]

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings.

The flat plate 1 has a desired shape such as a rectangular shape or a square shape according to the wall surface shape at the place of use, and it is preferable to use a veneer plate, a sizing board or an FRP plate. An adhesive 2 made of an epoxy resin is applied over the entire surface of one side of the flat plate 1, and a granular inorganic material 3 such as sand or silica is attached to the upper surface of the adhesive 2.

The base material is attached to a wall surface of a building by being struck on a crosspiece, and the upper surface of the granular inorganic material 3 is directly coated with mortar or the like to be covered with tiles to form a wall surface.

[0013]

EFFECTS OF THE INVENTION Since the finishing base material of the present invention can adhere the particulate inorganic substance to the plate surface by using the epoxy resin adhesive in the factory, the epoxy resin adhesive can be transported to the construction site as in the conventional case. Therefore, there is an effect that the epoxy resin adhesive is not wasted and the cost can be reduced.

Further, after being attached to a building, it is possible to directly apply cement mortar without adhering a granular material to the surface and performing a base treatment, and there is an effect that working efficiency is improved.
