Abstract

PURPOSE:To easily and efficiently produce a good joint part by sticking a non-water-absorptive or low-water-absorptive surface-dressed board on a backing board, so that the shrinkage due to hardening of a joint material at the time of manufacture of a panel can be prevented. CONSTITUTION:A low-water-absorptive or non-water-absorptive surface-dressed board 2 is stuck on the surface of a backing board 1, and a joint, material 3 is filled in joint gaps, and then the joint material 3 is pressed by a water- absorptive free roller 6, so that the water inside the joint material 3 is absorbed by the water-absorptive free roller 6. Thereby, the joint material 3 can be closely and densely filled in the joint gaps, and the occurrence of shrinkage due to hardening can be prevented. Thus, a good joint part 5 can be easily and efficiently formed.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a jointing method for a panel in which a surface decorative plate such as a tile is attached to a base board, and more particularly to a non-water-absorbing or low-water-absorbing surface cosmetic for a porcelain tile or a marble plate. The present invention relates to a jointing method for a panel formed by attaching a plate.

[0002]

2. Description of the Related Art A panel made by pasting a surface decorative plate such as a tile or a marble plate on a surface of a base board and filling a joint material in a joint space between the surface decorative plates reduces the number of on-site work steps. It is widely used as various interior and exterior materials because it can reduce labor cost and shorten the construction period.

Conventionally, such a panel is shown in FIG. 2 (a).
As shown in FIG. 2, the surface decorative plate 2 is attached to the surface of the base board 1, and the joint material 3 kneaded with water such as mortar is filled in the joint space between the surface decorative plates 2 and then, as shown in FIG. As shown in the figure, the joint joint 4 made of rubber is used to hold the joint and then
It is manufactured by curing the joint material 3.

In the method of manufacturing such a panel, if the side surface of the surface decorative plate 2 is highly water-absorbing, the water content in the joint material 3 packed in the joint space between the surface decorative plates 2 is the surface. Water is absorbed from the side surface of the decorative plate 2, and the joint material 3 is in a state of being densely filled, so that a good cured joint portion 5 is obtained as shown in FIG. 2 (c). However,
The surface decorative plate 2 is made of porcelain tile, marble, stone, etc.
In the case of a non-water-absorbing or low water-absorbing material, there is no absorption of moisture in the joint material to the surface decorative plate 2 side, and the joint material 3
Since it is not possible to densely fill the joints, the joint portion 5A formed after curing has a large surface depression, as shown in FIG. 2 (d). That is, since the joint portion 5A is thinned by curing, a good joint portion cannot be formed (hereinafter, this phenomenon may be referred to as "curing thinning" of the joint material).

Therefore, conventionally, when a panel is manufactured using a non-water-absorbing or low-water-absorbing surface decorative plate, the joint material is filled and cured, and then the joint material is filled and cured twice. A method is used in which filling is performed or mortar that is harder than usual is used as the joint material.

[0006]

However, the double filling of the joint material is very troublesome, and the workability of the filling is poor with the hard-mixed mortar, so that the work is also troublesome. .

The present invention solves the above problems of the prior art, prevents non-water-absorbing or low-water-absorbing surface decorative plates from being adhered to a base board, and prevents the joint material from hardening and thinning when a panel is manufactured. An object of the present invention is to provide a method for easily and efficiently manufacturing a joint portion.

[0008]

A method for filling a joint of a panel according to a first aspect of the present invention is a joint of a panel in which a joint material mixed with water is filled in a joint gap between surface decorative boards attached to the surface of a base board. In the filling method, the surface decorative plate is a low water-absorbing or non-water-absorbing one, and after filling the joint material in the joint space, the joint portion is pressed by a water-absorbing free roller,
The water in the joint material is absorbed by the water absorbing free roller.

According to a second aspect of the present invention, there is provided a method of clogging a panel according to the first aspect, wherein the water-absorbing free roller is a free roller having a sheet-like water-absorbing polymer mounted on an outer peripheral surface thereof.

[0010]

In the panel joint filling method of the present invention, since the joint material filled in the joint gap is pressed by the water absorbing free roller and the water in the joint material is absorbed by the water absorbing free roller, the surface decorative plate is Even if it is non-water-absorbing or low-water-absorbing, the joint material can be densely filled in the joint space without hardening or thinning. This roller is a free roller and presses it from above without rubbing the joint.

According to the method of claim 2, the water absorption free roller can easily and efficiently absorb the moisture of the joint material, and the workability is improved.

[0012]

Embodiments of the present invention will now be described in detail with reference to the drawings.

FIG. 1 is a cross-sectional view showing an embodiment of a method for clogging a panel according to the present invention.

In the method of this embodiment, first, a non-water-absorbing or low-water-absorbing surface decorative plate 2 such as a porcelain tile, a marble plate or a stone material is attached to the surface of the base board 1, and then this surface decorative plate. The joint material 3 kneaded with water is filled in the joint space between the two comrades (Fig. 1 (a)).

Then, a water-absorbent polymer sheet 6A is formed on the outer peripheral surface.
The free roller 6 mounted with is applied to the joint portion filled with the joint material 3 so that the water content of the joint material 3 is absorbed by the water-absorbent polymer sheet 6A (FIG. 1 (b)).

After that, the joint bar 4 made of rubber is pressed against the filling portion of the joint material 3 to hold the joint (FIG. 1 (c)), and then the joint material 3 is cured to form the joint portion 5.

According to such a method of the present invention, it is not necessary to pack the joint material twice, and without hardening mortar, hardening and thinning can be prevented to form good joint portions. Is possible.

[0018]

As described in detail above, according to the method for filling a panel joint of the present invention, in manufacturing a panel to which a non-water-absorbing or low-water-absorbing surface decorative plate is attached, the surface decorative plate It is possible to densely fill the joint space with the joint material and to easily and efficiently form a good joint portion. Since the free roller is used, the water absorbent member does not rub the joint portion, and the joint surface becomes smooth.

According to the panel joint filling method of claim 2,
Joint filling workability is further improved.
