Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a large thin plate pasting method for pasting a large thin plate such as an extremely large thin cut stone to a base such as a wall.

(Conventional technology) Natural stones such as marble are highly decorative, and in recent years, technology has been developed to process natural stones into ultra-thin cut stones with a thickness of approximately 5+n+n. Cut stone has been widely used as a finishing material.

A conventional method for attaching thinly cut stone is to directly attach the thinly cut stone to a base such as concrete or mortar using a two-component poxy adhesive.

(Problems to be Solved by the Invention) However, when attaching thinly cut stones using the direct attaching method, it is easily affected by the unevenness of the base, and it is difficult to attach relatively large thinly cut stones. Therefore, it is necessary to increase the precision of the construction of the base, but increasing the precision of the construction of the base increases the effort and cost of constructing the base. Therefore, in the past, thinly cut stones up to about 900 squares were pasted. Therefore, when attaching thinly cut stones to large floors, walls, etc., it is necessary to line up and attach a large number of thinly cut stones that are smaller than the above-mentioned size.
In that case, a joint of about 6 m/m will be provided between the thinly cut stones, which is no longer desirable in terms of appearance. For this reason, in order to reduce the number of joints as much as possible, conventionally the thinly cut stones are joined by butting, thereby improving the appearance.

However, when joining by butting, cracks may occur in the thinly cut stones or the thinly cut stones may float due to the behavior during an earthquake. In addition, since the method of attaching thin-cut stone is by pressure bonding or gluing, the unevenness of the base is ±5 mr.
If it exceeds n/2m, it becomes difficult to apply the cut stone and it becomes impossible to obtain a good finish. Therefore, it is still necessary to increase the precision of the construction of the base, and the same problems as described above still occur.

The present invention was made in view of these problems, and its purpose is to easily and accurately attach a large thin plate to a base without having to form the base very high and with high precision. The purpose of the present invention is to provide a method for attaching large thin plates.

Another object of the present invention is to provide a method for attaching large thin plates that can achieve a good finish by reliably attaching large thin plates to a base.

(Means for Solving the Problems) In order to solve the above-mentioned problems, the present invention involves partially painting or applying polymer cement mortar or adhesive on a large thin plate as a base (hereinafter referred to as the Petane method). It is characterized by pasting.

(Function) In the method for attaching large thin plates according to the present invention having such a configuration, the large thin plates are attached to the base by the Petane method, so the large thin plates are coated with relatively thick polymer cement mortar or It can be attached to the base using adhesive. That is, the base surface and the thin plate are separated by a certain distance. Therefore, the base surface to which the large thin plate is attached does not need to be formed with such high precision, and it becomes possible to easily and reliably attach a relatively large thin plate to the base surface with high precision.

(Example) Hereinafter, the present invention will be explained in detail using the drawings.

Figure 1 shows an example of the large thin plate pasting method according to the present invention when thin cut stone is used as the thin plate.
A sectional view taken along line I and FIG. 2 are a front view of this embodiment. In the figure, 1 is the inner wall s, 2 is the concrete bottom a on the inner wall, 3 is the polymer cement mortar that is the coating material, 4 is the large thin cut stone, 5 is the level tree, 6 is the bundle, 7 is the falling prevention member, and 8 is the falling prevention member. It is a filling material.

As shown in FIGS. 1 and 2, a large, thinly cut stone 4 is attached to a concrete base 2 of an inner wall 1 of a building with a polymer cement mortar 3 interposed therebetween.

To attach the thinly cut stone 4, first apply polymer cement mortar 3 to the concrete base 2 of the inner wall 1 in several rows (in the illustrated example, 4 rows) per thinly cut stone 4 in the form of vertical stripes as shown in FIG. ) to smear. The cross-sectional shape of this polymer cement mortar 3 is formed into an isosceles triangular mountain shape using a metal trowel, for example, as shown in FIG. Of course, the polymer cement mortar 3 may have other shapes. As this polymer cement mortar 3, for example, "ST mortar" manufactured by Nippon Kasei ■ is used. Next, a large thinly cut stone 4 is applied to the applied polymer cement mortar 3. In that case, in order to improve the adhesion of the cut stone 4, epoxy resin is applied to the back surface of the cut stone 4, or No. 5 silica sand is sprinkled on the epoxy resin.

Further, in order to prevent cracks in the concrete base 2, a butyl rubber sheet (not shown) is pasted on the back surface of the thinly cut stone 4. Furthermore, by setting a leveling tree 5 on the floor 6 and placing the lower end of the thinly cut stone 4 on this leveling tree 5, the level of the thinly cut stone 4 is adjusted to a predetermined level, and the upper end of the thinly cut stone 4 is adjusted to a predetermined level. By engaging the falling prevention member 7 fixedly installed on the inner wall portion 2, the thinly cut stone 4 is prevented from falling.

Then, when the adhesive strength of the polymer cement mortar 3 is developed and the cut stone 4 is attached to the inner wall part 1, the space between the base 2 and the cut stone 4 is filled with a filler 8. As the filler 8, for example, a filler such as lightweight mortar, plaster, or dry mortar can be used. Finally, the leveling tree 5 is removed and a member (not shown) having a buffering effect is inserted and installed after the leveling tree 5 instead. With this buffer member, even if the thin cut stone 4 is affected by the inner wall part 1,
It is made not to be affected by the floor 6.

In this way, the cut stone 4 attached to the inner wall 2 has relatively large dimensions, for example, 900 x 2800 x 8 (mm), and therefore, as is clear from the figure, the upper end of the cut stone 4 is It extends to a position exceeding the ceiling height h. Therefore, no joints extending in the lateral direction are formed in the thinly cut stone 4, and the appearance becomes extremely luxurious and good-looking. The inner wall is finished by arranging an appropriate number of such thinly cut stones 4 in parallel in the lateral direction depending on the width of the inner wall portion 1. In that case, vertical joints a of approximately 61 in size are formed between the thinly cut stones 4, but since there are no horizontal joints, the overall design effect of the inner wall portion 2 is improved. do. Note that this joint a is sealed with a suitable sealing material.

This embodiment using the polymer cement mortar 3 is applied when the accuracy of the unevenness of the concrete base 2 is ±21/2 m or more.

FIG. 4 is a diagram similar to FIG. 2 showing another embodiment of the present invention. It should be noted that the same components as those in the above-mentioned embodiments are given the same reference numerals, and detailed explanations thereof will be omitted.

In this embodiment, an adhesive 9 such as an epoxy resin or an elastic adhesive is used as the polymer cement mortar 3.
The thinly cut stone 4 is attached to the inner wall part 1 by streaks and dots. That is, in the case of applying streaks, as shown in the upper half of FIG. Several rows are formed at predetermined intervals, and the thinly cut stones 4 are applied to these rows, and then the thinly cut stones 4 are attached to the inner wall portion 2 in the same manner as in the above-described embodiment. The shape of the adhesive in this case can also be formed, for example, in the shape of an isosceles triangular mountain, similar to the above-described embodiment.

In addition, in the case of point pasting, as shown in the lower half of the figure, the adhesive 9 is applied to the inner wall part 2 in a bump shape on the top and bottom, left and right,
A thinly cut stone 4 is applied to this bump-shaped application portion 9b and attached to the inner wall portion 2 in the same manner as described above. In that case, the application pitch of the streak-like application part 9a and the bump-like application part 9b of the adhesive 9 is
If the precision of the concrete base 2 and the size of the cut stone 4 are determined, the cut stone 4 can be stuck even more effectively. When a plurality of thinly cut stones 4 are pasted side by side, a vertical joint a having a width of about 61 mm is formed between the thinly cut stones 4, as in the previous embodiment.

In addition, in this embodiment, the upper half of the cut stone 4 is pasted by pasting the lines, and the lower half is pasted by pasting the dots. It can also be done.

In this example, in which the adhesive 9 is used for the polymer cement mortar 3, the accuracy of the unevenness of the concrete base 2 is ±5 m + n.
/2m or less.

Although the present invention has been described in detail above, the present invention is not limited to these embodiments, and various design changes are possible.

For example, in all of the above-mentioned embodiments, the cut stone 4 is attached to the inner wall 1, but the present invention can also be applied to the case where a thin plate such as a decorative board made of a material other than stone is attached to the inner wall 1. .

Further, in all of the above-described embodiments, the base to which the large cut stone 4 is attached is the concrete base 2, but the present invention can also be applied to a base made of other materials such as mortar.

Further, in each of the above-described embodiments, the cut stone 4 is attached to the inner wall 1, but it goes without saying that it can also be applied to other locations such as the floor or ceiling.

(Effect of the invention) As is clear from the above explanation, according to the large thin plate pasting method according to the present invention, the large thin plate is pasted to the inner wall by the Petane method, so that the large thin plate is pasted on the inner wall. Even if the ground is not formed with such high precision, a relatively large thin plate can be easily and reliably attached to the base with high precision. Therefore, when attaching the thin plate to, for example, an inner wall, there are no horizontal joints, and the cracks and lifting that conventionally occur at such horizontal joints are eliminated. This makes it possible to achieve an extremely good finish.
