Description

TECHNICAL FIELD The present invention relates to a method for producing a composite building material in which a surface finishing material such as a tile is applied to the surface of a base material such as a cement extruded board, and more specifically, The present invention relates to a method for manufacturing a composite building material in which a surface finishing material and a base material are firmly bonded and surface accuracy is ensured.

[Prior Art] Conventionally, a surface finishing material is applied to the surface of a building, but due to the trend toward higher quality of building materials, a surface finishing material such as a tile is mainly adhered to a base material such as a cement extruded board. An integrated building material is manufactured and constructed by fixing with. In addition, in the case of large-sized tiles, metal fittings are also used together to prevent them from coming off.

Further, as such a technique, a building material in which a dovetail-shaped projection is fitted in a dovetail-shaped groove to prevent the building material from falling off is actually developed.
No. 0 is disclosed.

Furthermore, in the microfilm of Japanese Utility Model Application No. 59-77288 (Japanese Utility Model Application Laid-Open No. 60-188708), a fitting portion is formed on the surface of a cement plate having a hollow portion, and is fitted into this fitting portion. Described is a building composite material in which small tiles each having a portion formed on the back surface are fixed to each other. At this time, the cement plate 4 and the tile 6 are fitted with an adhesive, a mortar, a resin mortar, or the like. It has been shown that they may stick together at the same time.

[Problems to be Solved by the Invention] However, in the conventional composite building material, since the tile of the surface finish material is fixed only by the adhesive, there is a risk of peeling. Especially in the case of large-sized tiles, there is a problem that the danger is greater.

Moreover, it is difficult to make the surface accuracy of these post-bonding sufficiently satisfactory.

Further, in the building material described in Japanese Utility Model Laid-Open No. 60-11940, the dovetail-shaped projection is used as a guide to fit the dovetail-shaped concave groove. Not only is it difficult to apply the work, but also the surface accuracy is not sufficient.

In the construction composite material described in the microfilm of Japanese Patent Application No. 59-77288, since it is fixed with an adhesive or the like at the time of fitting, it is difficult to completely fill the gap with the adhesive in such a case. Since voids remain, there is a problem that if rainwater enters the voids after construction, it will cause frost damage, and if you increase the adhesive supply to prevent this, the gap between the tiles will increase. There is a problem that the adhesive leaks out from the tile and stains the tile surface.

Therefore, as a result of various studies from the standpoint of prevention of peeling and surface accuracy, the present inventor found that by filling the gap in the fitting portion with a bonding agent, further improvement of the separation prevention and good surface accuracy can be obtained. The present invention has been made based on this.

Therefore, an object of the present invention is to provide a method for manufacturing a composite building material, which can prevent the danger of peeling and ensure safety, and also ensure high surface accuracy of the finished surface.

[Means for Solving the Problems] The objects of the present invention are: 1) In a method for producing a composite building material in which an extruded plate and a surface finishing material are combined, a dovetail or dovetail groove is formed on the surface of the extruded plate. On the other hand, the back surface of the surface finish material is formed with dovetails or dovetails that mutually fit with the dovetails or dovetails formed on the extruded plate, and after fitting these, the above-mentioned surface finish Manufacture of a composite building material characterized in that a gap is formed between the materials and in a state where a sealing material is provided on the side surfaces of the extruded plate and the surface finish material on both sides of the extruded plate, and the gap is formed between them. Method, and 2) When filling the gap described in the first paragraph with a bonding agent, at least the surface side of the surface finish material is fixed by an adsorption device to ensure surface accuracy and to form a predetermined gap. It was achieved by each method of manufacturing composite building materials.

Hereinafter, the present invention will be described in more detail.

The composite building material used in the present invention is one in which a surface finishing material is bonded to an extruded plate, and as this extruded plate, various ones conventionally used in this technical field are used, preferably cement. An extruded plate is used.
This extruded plate has, for example, a hollow portion, and is provided with irregularities on its side surface so that it can be engaged with another extruded plate.

Tiles are mainly used as the surface finish material. A desired shape is used as the shape of the surface finish material, and for example, a polygon such as a triangle, a quadrangle, a pentagon, a hexagon or a circle,
Examples include an elliptical shape.

The extruded plate and the surface finish are provided with dovetails and dovetails as fitting parts, which are preferably provided during extrusion or during tile formation.

The surface of the extruded plate is provided with either a dovetail or a dovetail, and the surface finish is provided with either a dovetail or a dovetail, which are in a mutually fitting relationship. Further, when the fitting portion is provided on the back surface of the large-sized tile, a plurality of fitting portions are provided, and in the case of all dovetails, dovetails and dovetail grooves are provided in the case of all dovetails. In some cases, the fitting portion of the extrusion-molded plate is either a dovetail or a dovetail groove corresponding to these cases.

A bonding agent is filled in a gap formed by fitting the fitting portion of the extruded plate and the fitting portion of the surface finish material. As this bonding agent, mortar or resin type adhesive system or the like is used.

As a method of filling the gap of the fitting portion with this bonding agent, it is preferable to fill the gap from the side surface of the building material.
Further, an adsorbing device is used for this gap because it is necessary to ensure the surface accuracy of the building material surface, and this adsorbing device keeps the building material to have a constant thickness or surface smoothness.

The suction device used in the present invention applies a suction pad having good flatness to the back surface of the extruded plate or the smooth surface of the surface finish material to form a desired gap in the fitting portion between the extruded plate and the surface finish material. To do. In this state, the bonding agent is filled.

In the extrusion-molded plate manufactured as described above, when the surface finish material provided on the surface of the extrusion-molded plate has a gap between the surface finish materials (joint), mortar or the like is placed in this gap. It is common practice in this technical field to fill the above-mentioned material as a cosmetic finish, and a cosmetic finish is usually provided as necessary.

[Operation] In the method for manufacturing a composite building material of the present invention, since the space between the extruded plate 2 and the surface finish material 1 is opened by using an adsorption device in order to fill the space in the fitting portion with the bonding agent, adhesion is achieved. The agents are easy to inject and thus increase their bond strength, are safe without the risk of a strong bond breaking off. Further, the surface accuracy of the building material surface can be ensured by the filling ratio of the bonding agent and the adsorption device.

Example As shown in FIG. 1, an extruded plate 2 having a dovetail 7 having a size of 30 cm × 2 m and having a hollow portion 10 was manufactured from a semmet material. The extruded plate 2 has a convex portion 4 and a concave portion 5 on its side surface.

On the other hand, as the surface finishing material, a tile having a dovetail groove 6 that fits into the dovetail, a large tile 1 of 10 cm × 30 cm was manufactured.

As shown in FIG. 1, these extrusion molded plate 2 and tile 1 are fitted with dovetail grooves 6 of the tile in dovetails 7 of the extrusion molded plate,
Inject the mortar 3 into the gap formed between them,
A composite building material A capable of suppressing rattling and firmly adhering the tile 1 to prevent peeling was completed. When the tensile strength of this composite building material was measured, it showed a very high value of 25 kgt / cm ^2, and at a value above this value, the extruded plate was broken from the dovetail portion.

The composite building material A was manufactured using the adsorption pad shown in FIG. That is, when a 30 cm square tile is provided on a 60 cm x 2 m extruded plate to form a composite building material, smooth surfaces are adsorbed on both sides of the fitted extruded plate and tile.
While being sucked in, the gap was filled with mortar as a binder and cured. The surface accuracy of the composite building material thus obtained was very good, within 0.2 mm.

[Effects of the Invention] In the manufacturing method of the present invention, a surface finish material is fitted to an extruded plate, a joint material and a sealing material are provided, and then a gap is filled with a bonding agent, so that a sufficient amount is supplied. However, there is no leakage between the surface finish materials, and therefore the surface of the surface finish material is not contaminated.

Further, since a sufficient amount of the bonding agent can be supplied, the void is not completely left due to insufficient filling, and the void is completely filled. Therefore, there is a remarkable effect that there is no fear of adverse effects such as frost damage.

Furthermore, when manufacturing a composite building material, since at least the surface side of the surface finish material is fixed by an adsorption device and then the gap is filled with a bonding agent, the surface accuracy between the surface finish materials can be ensured with high accuracy and easily. It has an excellent effect that it can be done.
