Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a bonding device for a mosaic tile unit in which a desired number of tiles are bonded to a mount with joint gaps, and more specifically, the present invention relates to a device for bonding a mosaic tile unit using static pressure caused by atmospheric pressure. This invention relates to a pasting device for mosaic tile units.

Conventional tiling involves pressing the tile against the cement mortar surface painted on the base side and hitting it with a mallet, etc., whether it is a mosaic tile unit, small tiles, double tiles, or other single tile tiles. Or, it was done by pressing a vibrator. (Note: This can also be done by applying cement mortar to the back side of the tile.) However, in either case, there is variation in the pressure applied to each tile, which makes it difficult to maintain a uniform adhesive strength as a whole. This is difficult to do, and both in the case of hitting and using a vibrator, the vibrations may be transmitted to the tiles that have already been pasted on, causing the tiles to float or move, which is extremely undesirable.

The present invention has been made by focusing on the above points,
SUMMARY OF THE INVENTION An object of the present invention is to provide a mosaic tile unit pasting device that can apply uniform pressure to each part using static atmospheric pressure.

Another object of the present invention is to provide a mosaic tile unit pasting device which eliminates adverse effects on surrounding tiles during pasting, makes the entire construction area beautiful, and provides a long service life.

Another object of the present invention is to reduce operator fatigue by eliminating the need for manual pressure during pasting work, thereby increasing efficiency, and requiring less manual effort during pressure application. To provide a mosaic tile unit pasting device which allows good work to be done without requiring skilled workers.

Another object of the present invention is to provide a gluing device for mosaic tile units that prevents the generation of air bubbles and obtains good adhesion by removing air between cement mortar and tiles during gluing. It is on offer.

Next, an embodiment of the present invention capable of achieving the above object will be described in detail with reference to the accompanying drawings.

Figure 1 is a side view of the entire device, Figure 2 is a plan view of the same as above, Figure 3 is a bottom view of the tile unit to be pasted attached to the operation panel, and Figure 4 is a longitudinal cross-section of the tile unit in the state of being pasted. The side view and FIGS. 5 to 7 are longitudinal sectional side views of the rotary valve section showing ventilation switching during construction. In Figures 1 to 4, A is the operation panel, B is the vacuum pump, C is the desired number of tiles _C1 , and this tile.
_C1 is a tile unit consisting of a mount _{C2 pasted with joints C3 ,} D is cement mortar, and E is the base.

The operation panel A includes a rigid plate 1 formed to have the same dimensions as the tile unit C, an elastic plate 2 (for example, relatively hard rubber, etc.) adhered to the entire back surface of the rigid plate 1, and a rigid plate. A cover plate 3 on the hard material side is fixed in an airtight manner to the four sides of the upper surface of the body 1 and on the four sides of the elastic plate body 2, and a handle part 4 is fixed on the rigid plate body 1.
a gripping body 4 having a shape, a cylindrical airtight casing 5 inserted into the gripping body 4 and equipped with a rotary valve for switching ventilation, connected to the airtight casing 5,
It is composed of an intake pipe 6, a main ventilation pipe 8, a sub-ventilation pipe 9, and an atmosphere communication pipe 10, which pass through the grip body 4.

The height of the cover plate 3 is such that when the operation panel A is set on the tile unit C, its lower edge 3a protrudes slightly from the bottom surface of the tile unit C.

The other end of the intake pipe 6 is connected to a vacuum pump B via a flexible pipe 7.

The other end of the main ventilation pipe 8 passes through the rigid plate 1 and the elastic plate 2 and opens on the back surface of the elastic plate 2.
The opening position is formed so that when the operation panel A is set on the tile unit C, it penetrates the mount _C2 and is located at the joint _C3 near the center of the tile unit C (the third (see figure).

A U-shaped branch pipe 9a is connected to the other end of the subventilation pipe 9, and the four tips of the branch pipe 9a are connected to the rigid plate 1.
and an opening is formed on the back side of the elastic plate body 2 through the elastic plate body 2, and the opening position is at each tile C ₁ at the four corners of the tile unit C when the operation panel A is set on the tile unit C. Mount C ₂ in the approximate center of
(See Figure 3).

In Figs. 5 to 7, 11 indicates valves 11a and 11b.
12 indicates a rotating shaft, and the rotating valve 1
1 is mounted horizontally in the airtight casing 5 via a rotation shaft 12, and the rotation shaft 12 is led out to one side of the grip body 4, and a lever 13 is fixed to this lead-out portion. Then, the intake pipe 6, main ventilation pipe 8, sub-ventilation pipe 9, and atmosphere communication pipe 10 are cut off by the valves 11a and 11b (see Fig. 5), or the intake pipe 6 and the sub-ventilation pipe 9 are communicated with each other (see Fig. 6). Reference) Intake pipe 6 and main ventilation pipe 8
(see Fig. 7), and when the intake pipe 6, main vent pipe 8, sub-ventilation pipe 9, and atmosphere communication pipe 10 are cut off as shown in Fig. 5, the atmosphere communication pipe 10 is configured to communicate with the main ventilation pipe 8 and the sub-ventilation pipe 9.

In the configuration described above, the elastic plate 2 of the operation panel A is attached on top of a number of stacked tile units C (note: stacked with the mount C ₂ facing upward). (note,
In a state where the four sides of tile unit C are surrounded by cover plate 3. ) Next, the lever 13, which is in the OFF position as shown in FIG. 5, is pushed forward as shown in FIG. 6 using the tip of a finger to communicate the intake pipe 6 and the subventilation pipe 9, and at the same time, the vacuum pump B is driven. In such a case, one sheet of the tile unit C is attracted to the elastic plate ₂ through the mount C2 by the suction force at four points at the tips of each branch pipe 9a communicating with the subventilation pipe 9.

Then, one tile unit C attracted to the operation panel A is moved to the construction site.

Next, the tile unit C is brought into contact with a predetermined position on the cement mortar surface D, which has been previously applied to the base E. At this time, the lower edge 3a of the cover plate 3 is immersed in the cement mortar D, the tile unit C is cut off from the outside air, and the tip of the main ventilation pipe 8 is inserted into the mount C ₂
It penetrates through and opens into a joint _C3 near the center of the tile unit C.

Next, the lever 13 is tilted forward as shown in FIG. 7 to connect the intake pipe 6 and the main ventilation pipe 8. Then, the air existing between each tile C ₁ of the tile unit C and the cement mortar D is extracted and a negative pressure is created. At the same time, atmospheric pressure acts on the surface of the rigid plate 1, and the tile C ₁ is moved through the elastic plate 2. It is pressed into cement mortar D. At this time, irregularities in the thickness and surface of the tile C ₁ itself are absorbed by the elastic plate 2. Next, the vacuum pump B is stopped and the lever 13 is returned to the OFF position shown in FIG. A is separated from tile unit C, and the same operation is then repeated to successively attach the tiles.

As described above, the present invention can perform bonding using static pressure due to atmospheric pressure, so that the bonding can be performed with equal pressure on each part,
Moreover, it eliminates the negative impact on the surrounding tiles during gluing, in other words, the entire installation area can be made beautiful, and it has a long service life, and it does not require manual pressure during gluing, as is the case in the past. Reduces worker fatigue and increases efficiency.
And by not requiring manual adjustment when pressurizing,
It can be easily operated without the need of a skilled worker, and furthermore, it has the effect of preventing the generation of air bubbles by removing the air between the cement mortar and the tile during adhesion.
