Abstract

PURPOSE:To prevent the offset joint of thin stones leading to a crack by arranging natural very-thin stones in each of which a first sheet having a cushioning property is shiftingly stuck on the backside thereof and providing a second sheet on the backside of the projecting portion of the thin stone. CONSTITUTION:A sheet 6 having nearly the same size as a natural thin stone 2 while having a cushioning property is stuck on the backside of the thin stone 2 via a sheet 7 made of glass fabric, rubber, etc. being shifted by a defined length. The thin stones 2 are stuck on a backing 1 one after another by means of a flexible adhesive 10. Then, the sheets 6 are engaged with each other by means of tenons having detents while the sheet 6 on the projecting portion 9 is joined to an adjacent thin stone 2 by means of a butyl sheet 8. Thereby, the thin stones are not affected by any possible displacement such as a crack generated on the backing 1 due to the flexible adhesive 10 while preventing an offset joint since the adjacent thin stones 2 are joined to each other by means of the sheet 8.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a method of pasting and applying natural ultra-thin stone (hereinafter simply referred to as thin stone) as a finishing material for floors or walls. It is.

[Conventional technology] Natural stone is highly decorative, and with the development of a technology that can process natural stone into ultra-thin stones with a thickness of about 5 mm, recent years have seen the use of natural stone for making floors or walls. Thin stone is widely used as a finishing material, and its construction is carried out by directly pasting the thin stone with a two-component poxy adhesive onto a base such as concrete or mortar that has been finished with a metal trowel. was common.

[Issues to be solved by the invention] [1] However, in the conventional construction method, mistakes may occur in the joints of the thin stones, and since the thin stones are attached directly to the base, cracks etc. that occur in the base may occur. There was a problem in that the displacement affected the surface of the thin stone. The situation is shown in Part 8.
As shown in the figure. In the figure, 1 is the base, 2 is the thin stone, 3 is the epoxy adhesive, 4 is the crack that occurred in the base 1, and 5 is the crack that occurred in the thin stone 2. In Fig. 8, the thin stone 2 is pasted on the base 1 with a two-component poxy adhesive 3, but if the base 1 has unevenness, there will be a step, or misalignment, at the joint of the thin stone 2. . Further, since the thin stone 2 is directly attached to the base 1, there is a problem in that when a crack 4 occurs in the base 1, a crack 5 is also induced in the thin stone 2.

The present invention solves the above-mentioned problems, and aims to provide a method for attaching natural ultra-thin stones that can prevent misalignment of thin stones and the occurrence of cracks in the base.

[Means for Solving the Problems] In order to achieve the above object, the method for pasting natural ultra-thin stones of the present invention provides a method for pasting natural ultra-thin stones on the back side of which has cushioning properties of approximately the same size as natural ultra-thin stones. When pasting the natural ultra-thin stones that are pasted by shifting the first sheet by a predetermined amount to the base one by one using a flexible adhesive, the protruding portion of the first sheet and the adjacent natural ultra-thin stones are different from each other. It is characterized in that it is joined through two sheets.

[Function] In the present invention, when attaching the thin stone to the base, a first sheet made of rubber or the like having approximately the same size as the thin stone is attached to the back surface with a slight shift. Since the adhesive is used, it will not be affected even if there is a crack or other displacement in the base, and the protruding part of the first sheet and the adjacent thin stone are covered with a second sheet such as a butyl sheet. Since they are joined together, misalignment can be prevented.

[Example code] Examples will be described below with reference to the drawings.

FIG. 1 is a diagram showing an example in which the method for pasting natural ultra-thin stone according to the present invention is applied to floor finishing.

Components that are the same as those in FIG. 7 are given the same numbers. The same applies below. Also, below, the size of thin stone 2 used is GOO
x 400 x 8.

In FIG. 1, on the back side of the thin stone 2, there is a sheet 6 made of glass cloth, which is approximately the same size as the thin stone, and has cushioning properties.
They are pasted with a predetermined length shifted through a sheet 7 (thickness: 1 -) of rubber or the like. The reason for shifting the sheet 8 is as follows.

In other words, if the 7-toe 6 is shifted, the adjacent thin stones will be placed on one sheet 6, and the difference in alignment will be only the error on the right bank of both thin stones. This is because differences can be prevented.

/-The material may be any material as long as it can absorb the unevenness of the base 1, but it is preferable to use rubber in consideration of durability, water resistance, etc., and a thickness of about 31111 mm is sufficient. Also in Figure 1, the thickness of spreadsheet 6 is 3-■
It is said that In addition, the method of shifting is sheet 6 of thin stone 2.
In order to overlap the sheet pasted on the adjacent thin stone, the sheet is shifted both vertically and horizontally as shown in FIG. 2. 9 in Figure 1
The length of the protruding portion shown by can be set to 20+■ as long as it is long enough to prevent misalignment. In addition, the first
Reference numeral 11 in the figure is a joint, and its width 12 is 5cm-1.The width of the chamfered portion 13 of thin stone 2 is 1cm.

Therefore, the length of the portion indicated by 16 in FIG. 2 is 26. .

It is.

Next, the thin stones 2 to which the sheets 6 are attached are sequentially attached to the base using an adhesive 10. Incidentally, when pasting the thin stone 2, it is a matter of course to mark out the floor joints. The thickness of the adhesive 10 is 1-1. As the adhesive, a visible adhesive for carpet tiles is used. In other words, this is because the movement of the base 1 can be blocked, so that even if a crack or other displacement occurs in the base 1, it will not have any effect on the thin stone 2. Further, the protruding portion of the sheet 6 and the adjacent thin stone are joined by a butyl sheet 8 having a thickness of one dragon. This can be temporarily fixed with the butyl sheet 8, and
Until the flexible adhesive hardens, the thin stones can be bonded and held together without any misalignment.Furthermore, by stopping the intersections of the thin stones with the butyl sheet 8, the intersections can be maintained even if they expand or contract due to temperature. This is done for reasons such as preventing stress from concentrating on the area.

If the size of the sheet 6 is the same as that of the thin stone 2, the adjacent sheets 6 will be arranged without any gaps, and in fact, it is better to do it this way unless there is a problem with the construction. In consideration of the accuracy of attaching the sheet 6 to the thin stone 2 or the expansion of the sheet 6 due to temperature, a certain amount of clearance shown at 14 is provided. In FIG. 1, the clearance 14 is made into two dragons. It is clear that in order to do this, the sheet 6 has to be made smaller in size than the stone 2 by two squares in length and breadth.

Figure 3 shows the floor finished in this way.

In FIG. 3, 21.2 and 23.24 respectively indicate thin stones, BIN k θ and 64 indicate rubber sheets attached to thin stones 2+12*, 2g, and 2a, respectively. The shaded part in the figure is the rubber sheet 6I,
A portion of the butyl sheet 8 pasted to join the adjacent thin stones 2t12 and 24 is shown. Figure 15
1 shows a portion where the clearance 14 in FIG. 1 appears as a discontinuity in the joint. The area of the 15 parts is 5×2−
Although this is not a problem, filling it with a suitable material can prevent dust from clogging. At that time, if the color is the same as that of the joint 11, the appearance can be improved.

In the above embodiments, the joints have been described as being formed integrally with the sheet 8, but it is obvious that the invention can be similarly applied to other joints.

In addition, regarding the arrangement of the sheets 6, if they are engaged with a tenon with a turn as shown in Fig. 4, the sheets 6 can be arranged more flatly, which further prevents misalignment of the thin stones. effective. An example is shown in FIG. Fig. 5a shows an example of a so-called Nemuri type joint in which thin stones 2 are arranged without gaps, and Fig. 5A shows an example of a so-called joint type joint in which thin stones 2 are arranged at a predetermined interval. is embedded. Further, FIG. 5C is similar to that shown in FIG. 1, and is an example of a so-called common type joint in which the joint 18 is formed integrally with the sheet 6. In either case, since the sheets 6 made of rubber are engaged with each other by tenons, it is possible to further prevent misalignment of the thin stones.

Above, an example has been described in which thin stone is used as a finishing material for a floor, but it is clear that the same method can be used when pasting thin stone on a wall. However, in this case, the adhesive must be selected appropriately depending on the base of the wall surface. Further, the material of the sheet 6, 7, 8 may be any material as long as it can achieve the intended purpose, and is not limited to the above embodiments. Furthermore, it goes without saying that the dimensions described in the above embodiments are merely examples, and can be changed as necessary.

[Effects of the Invention] As is clear from the above description, the present invention has the following advantages: (1) Misalignment of thin stones can be prevented by the joint part using the butyl sheet 8, and furthermore, the adjacent sheets 6 can be engaged with a tenon. By doing so, misalignment can be more effectively prevented. ■ Some irregularities on the base 1 can be absorbed by the action of the sheet 6. ■ Since a visible adhesive is used, cracks etc. on the base 1 can be prevented. It has excellent effects such as being not affected by displacement, and (1) making it possible to carry out interior work using thin stone without requiring any skill by unitizing the construction method of the present invention.
