Description

  The present invention relates to a wall surface building material, a wall surface building material mounting structure, and a wall surface building material mounting method for bonding a wall surface building material of a foam fired body to a wall surface.

Conventionally, as a method of adhering a tile (a general ceramic tile of non-foamed fired body), which is a kind of building material for wall surfaces, to a wall surface, a method of adhering the tile to the casing with mortar or an adhesive is used. In order to prevent tile loss and peeling due to interlayer displacement in the casing, or because of some dimensional differences (uneven dimensions) among individual tiles, joints with an interval of about 2 mm have been provided.
And in order to improve the aesthetics of the finished surface with a constant joint width, a construction method using spacers between adjacent tiles or using auxiliary tools has been adopted, and work efficiency is low. Had problems.

  As an improvement measure, as described in JP 2005-307499 A, a step is provided on the upper edge of the tile, a polymerization space is provided on the front side, a polymer is provided on the back side, and a tile is formed. A tile with a step on the lower edge, a polymer on the front side, and a polymerization space on the back side, with a protrusion on the step surface facing the polymerization space on the lower edge of the tile Protruding tiles were developed.

  As another improvement measure, a tile described in Japanese Patent Application Laid-Open No. 6-212771 of Patent Document 2 and having a side surface formed by an inclined surface whose surface side is displaced toward the center side, and a side surface of the tile facing each other are provided. And a panel formed by cutting and raising the engaging claws inclined along the surface of the tile at the fixed portion of the tile, and sealing the joints between the adjacent tiles with the side surfaces of the tile engaged with the engaging claws. A dry construction structure for tiles, in which the tiles were fixed to the plate, was developed.

On the other hand, some of the foamed fired bodies (glass and ceramics) that have been reduced in weight as building materials have been put into practical use. In the practical application, a relatively dense tissue coating layer may be provided on the surface from the viewpoint of improving strength. Has been tried.
As an example of the coating layer, a glassy material or a metallic material can be cited, and since the surface is a design surface, the application of color and tone has been studied.
For example, when the main part is foamed and fired glass and the coating layer is metallic, a reinforcing material such as metal is sprayed on the surface of the foamed glass described in Japanese Patent Application Laid-Open No. 2003-292343. Modified foamed glass with a film coated on the surface of foamed glass has been developed, and application development of lightweight foamed fired bodies including the modified foamed glass with improved strength is expected.

And, when adopting the foam fired body for the building material for wall surface, in the rectangular plate shape whose side surface is perpendicular to the front and back surfaces, a spacer is required in the same way as a general tile to make the joint constant, In the method of providing polymerization spaces, polymers and protrusions at the upper and lower edges, it is difficult to form a complex shape because the material is a foamed fired body, and the inclined surface of the side is engaged and held with an engaging claw However, in addition to requiring a panel having a complicated shape, it has a problem of workability that requires fixing work and locking work between the inclined surface and the engaging claw.
The problem to be solved is that the fired fired foam is used as a building material for wall surfaces, and a good finish with joints is constructed by a simple construction method.

The present invention is a glassy material on the surface of a plate-like raw material that is a low-strength foam-fired body , in view of the problem of good appearance and easy construction when adopting a foam-fired body for building materials for wall surfaces based on the above-described conventional technology. It is a building material for a wall formed by forming a fired layer or a metal sprayed film and cutting and forming this plate-shaped raw material into a rectangular plate shape with a predetermined dimension, and the four side surfaces are inclined surfaces whose surface side is displaced toward the center. The ridge line between the back surface and the four side surfaces is formed as a contact edge with the wall surface building material adjacent at the time of construction , and a coating layer for improving the strength is formed only on the surface, and the contact edge is formed. Only the corners are easily worn and damaged, and the wall surface building material is adhered to the wall surface in an adjacent state, so that it can be easily bonded without the need for additional members such as auxiliary tools, and the inclined surface is orderly. The above-mentioned problems are solved by forming naturally.

In short, the present invention forms a glassy fired layer or a metal sprayed film on the surface of a plate-shaped raw material that is a low-strength foam fired body , and the plate-shaped raw material is cut into a rectangular plate with a predetermined dimension. Having molding, the dimensions of a number of wall building materials easy construction lightweight is uniform, Ru can be a number of wall building materials and good appearance are arranged orderly.
In addition, the four side surfaces are inclined surfaces whose front side is displaced toward the center, and the ridgeline between the back surface and the four side surfaces is the contact edge with the adjacent wall surface construction material during construction , improving the strength only on the surface. Since only the corners forming the contact edge are easily worn and chipped, the ridge lines are in contact with each other, and the pair of inclined surfaces of the adjacent wall surface building materials It is possible to form an orderly joint joint, and even if a wall construction material is damaged due to the interlayer displacement of the wall surface, the defective part is limited to the back side due to the material characteristics, and the design surface of the surface is adversely affected. not, Ru can be to maintain a good appearance.
And since the coating layer (glassy fired layer, metal sprayed film) is provided only on the surface, the strength of the surface of the building material for the wall surface can be increased and the durability can be improved. is there.

The ridge line between the back surface and the four side surfaces of the next wall surface building material is brought into contact with the ridge line between the back surface and the four side surfaces of the bonded wall surface building material, and the wall surface building material is adhered to the wall surface in an adjacent state. Therefore, it can be easily constructed by simply abutting the ridgeline of the bonded building material for the wall surface as a mark, and there is no need to set the joint equivalent part on the construction surface of the wall surface. Construction is also easy from a viewpoint.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
As shown in FIG. 1, the building material for wall surface 1, 1a... According to the present invention is a lightweight fired body made of a main body 2 and has a coating layer 3 (a vitreous fired layer on the surface of the main body 2). As shown in FIG. 2, a large number of building materials for wall 1, 1 a... Are bonded and fixed to the wall (construction surface) 4 with an adhesive 5 as an interior / exterior material. It is what is done.

As shown in FIG. 1, the building materials for wall surface 1, 1 a... Are formed from a plate-shaped raw material (not shown) of a foamed fired body (for example, a rectangle having a side of several centimeters to several tens of centimeters, a square, The surface 6 is a design surface, the back surface 7 is an adhesive surface, and the four side surfaces 8, 8a are formed in a predetermined size and a predetermined shape.
The four side surfaces 8, 8a ... are not perpendicular to the front surface 6, the rear surface 7 and the wall surface 4 at the time of construction, and have a slightly inclined surface (inclination angle forming a joint with a predetermined width) whose front surface side is displaced toward the center. It is made.
In the relationship between the front surface 6 and the rear surface 7, the area of the front surface 6 is slightly smaller than the area of the rear surface 7, and the four peripheral edges of the front surface 6 (ridge lines 9, 9a ... between the front surface 6 and the four side surfaces 8, 8a ...). Are inward by a width T (about 1 mm) in front view from the four peripheral edges of the back surface 7 (ridge lines 10, 10a... Between the back surface 7 and the four side surfaces 8, 8a...).

With such a shape, each of the four side surfaces 8, 8 a... Becomes a semi-unit joint forming portion 11, 11 a. A semi-unit joint forming portion 11, 11a,...
Further, the ridgelines 10, 10a... Of the back surface 7 and the four side surfaces 8, 8a... Serve as contact edges with the wall surface building materials 1, 1a.

Next, the material etc. of the building material for wall surfaces concerning this invention are demonstrated.
The foamed fired body, which is the material of the main part 2 of the wall building material 1, 1a ..., is obtained by mixing a foaming agent with various ceramic raw materials such as ceramics and glass and firing them porously.
It varies depending on the type and blending amount of various raw materials and foaming agents, firing temperature and firing time, etc., but it has an infinite number of pores inside and on the surface, and is a non-dense structure. Thus, open pores are formed on the surface, and the entire foamed fired body is light and low in strength, and the entire surface is rough with open pores.
A coating layer 3 (a glassy fired layer or a metal sprayed film) is provided on the surface of the main body 2 to increase the surface strength.

When a specific example of the coating layer is glassy and the main part is a foamed fired body together with the manufacturing process,
After the release agent is applied to the inner surface of the container made of refractory material, a small amount of the coating layer material mixed with the raw material (glassy or other ceramic raw materials) mixed with pigment and flux is placed in the container, and then mainly discarded Glass is pulverized and finely pulverized, and a main part raw material mixed with a foaming agent such as silicon carbide or calcium carbonate is placed on the coating layer raw material in an appropriate thickness in a container and fired into a plate shape.
Then, the two-layer raw material of the coating layer raw material and the main part raw material is simultaneously fired, so that the main part raw material becomes foamed porous, the coating layer raw material is sintered and cured, and the two-layer raw material is sintered and integrated. Using the open pores on the surface of the main part raw material as an anchor, a vitreous fired layer that forms the coating layer 3 on the surface of the main part 2 is formed in a coating state on the surface of the plate-like raw material (not shown). .

A specific example of the coating layer is metallic and the main part is a foamed fired body is explained together with the manufacturing process. Mainly, waste glass is pulverized and finely pulverized, and a foaming agent such as silicon carbide and calcium carbonate is mixed to produce a refractory material. It is placed in a suitable thickness on the container or shelf plate and fired into a plate shape.
Next, zinc, aluminum, or an alloy is arc sprayed on the surface of a plate-like raw material (not shown) of the foamed fired body to be the main body 2, and the surface of the main body 2 is coated using the surface open pores as anchors. The metal sprayed film which becomes the layer 3 is coated.

Then, the plate-shaped raw material (not shown) is cut into a predetermined shape (at least the front dimension) and a predetermined shape (at least four side surfaces 8, 8a of the inclined surface) into a plate-shaped building material 1, 1a for the wall surface. by forming, Ru coating layer 3 is formed only on the surface of the main body portion 2 in the wall building materials 1, 1a ....
In addition, in the cutting formation of the wall surface building materials 1, 1 a, the four side surfaces 8, 8 a, etc. are required to have a uniform size and an inclined surface, but the cutting is essential, but the front surface 6 and the rear surface 7 are not essential. In addition, since the surface 6 is a design surface (pattern forming surface), large and small irregularities may be formed by devising the mounting state of the main body raw material or the like before firing.
For example, when two-layer raw materials are fired simultaneously, unevenness is provided on the bottom surface inside the container, and when only the main part raw material is fired, unevenness is similarly provided on the bottom surface inside the container, or unevenly placed on the surface in a piled state. Put.
Moreover, although the foam glass was demonstrated as a specific example of the material of the wall surface building materials 1, 1a ..., it is good also as other foam baking products using the ceramic (ceramics) raw material.

Next, the building material mounting structure for wall surfaces according to the present invention will be described.
As shown in FIG. 2, the wall surface building materials 1, 1 a... According to the present invention are bonded to the wall surface 4 with an adhesive 5 (adhesive or adhesive mortar) and attached by a so-called crimping method. A large number of building materials 1, 1a,.
More specifically, on the back surface side of the building material for wall surface 1, 1 a, and the adhesive surface to the wall surface 4, the ridge lines 10, 10 a of the back surface 7 and the 4 side surfaces 8, 8 a. In contact with each other, the wall surface building materials 1, 1a,.

Next, the building material mounting method for wall surfaces according to the present invention will be described.
At the time of construction, for example, the building material for the wall surface 1, 1a ... is stacked upward, and the adhesive material 5 is applied to the surface of the wall surface 4 (or the back surface of the building material 1, 1a ... for the wall surface). 1, 1a... Are sequentially pressed and bonded to the wall surface 4.
During the sequential bonding, the ridgelines 10, 10a of the next-bonded wall construction material 1, 1a ... are applied to the back surface 7 and the ridgelines 10, 10a ... of the four side surfaces 8, 8a ... A large number of building materials for wall surface 1, 1 a... Are bonded in an adjacent state.

Next, the operation of the wall surface building material mounting structure according to the present invention will be described.
After the completion of the construction, a large number of wall building materials 1, 1 a... Are in contact with the ridge lines 10, 10 a... Of the back surface 7 and the four side surfaces 8, 8 a. The ridgelines 9, 9a ... of the front surface 6 and the four side surfaces 8, 8a ... in the ... are in a separated and parallel state, and the half-unit (width T) joint forming portion is sandwiched between the ridgelines 10, 10a ... Are adjacent to each other, and a pair of joint forming portions 11, 11a,... Having a width 2T (about 2 mm) are formed between the pair of ridge lines 9, 9a,.
In addition, with respect to the movement (interlayer displacement) of the wall surface 4 (frame) after the construction, that is, when an abnormal external force acts on the adjacent wall surface building materials 1, 1 a. The ridgelines 10, 10a on the back side are rubbed or pressed together, but the main part 2 of the wall construction material 1, 1a ... is porous foam and has a relatively low strength, so it is caused by abnormal external force. Abrasion and partial damage are limited to the back surface side centered on the ridgelines 10, 10a ... of the back surface 7 and the four side surfaces 8, 8a ..., and the wall surface building materials 1, 1a ... maintain the adhesion state to the wall surface 4. .
