Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a filler injecting attachment used for injecting, for example, an adhesive or other filler for repair into a part of a structural surface such as a wall surface or a floor surface of a building. More particularly, the present invention relates to a filler injection attachment used for securely fixing a floating tile on a tiled surface without damaging the tile.

For example, there is a structure in which a tile is adhered to the surface of a concrete frame via a base mortar in order to improve durability and aesthetic appearance of an outer wall of a tiled building. However, due to rainwater intrusion from joints, freezing, and other causes, the attached tile does not completely adhere to the base mortar, and a gap is generated between the two, and the tile may rise. In this case, it is necessary to perform a repair operation for injecting a slurry-like adhesive between the tile and the base mortar to fix the floating tile to the base mortar.

[0003]

2. Description of the Related Art Conventionally, a floating tile bonding method (repair method) by injecting an adhesive is performed by piercing a joint formed between tiles by pouring and bonding, or directly piercing a tile surface by pouring and bonding. There is.

The perforated portions 52 are joints 53 formed between the tiles 51, 51.
The adhesive 57 is filled into the gap 58 between the tile 51 and the base mortar 55 by pressure-injecting the adhesive 57 into the perforated portion 52, and the two are bonded and fixed.

FIG. 15 is a sectional view of a main part showing a second example of the conventional repairing method, and the same parts are denoted by the same reference numerals as in FIG. The same applies to FIG. 20 below. In FIG. 15, the perforated portion 52 has a range 51a several mm from the edge of the tile 51.
Are provided at the joint 53 so as to include According to such a method, since the base mortar 55 attached to the vicinity of the edge of the tile 51 is removed, the adhesive 57 can be reliably injected into the gap 58.

FIGS. 16 and 17 are sectional views of a main part showing a third example of the conventional repair method. As shown in both figures,
The perforated portion 52 is formed to a depth of about 30 mm from the surface of the body 54, and an adhesive 57 is injected into the perforated portion 52, and a full screw pin 59 (FIG. 16) or an anchor 60 is provided.
(FIG. 17) is reinforced to include the base mortar 55.

In FIG. 16, after the adhesive 57 is injected, the entire screw pin 59 is inserted, and a closed portion 61 made of epoxy resin or resin mortar is formed on the head. On the other hand, in the one shown in FIG. 17, after the anchor 60 is inserted and fixed in the perforated portion 52 in advance, the adhesive 57 is injected, and then the closed portion 61 is formed.

FIG. 18 is a front view of an essential part showing a conventional injection bonding method by perforating a tile surface. This repair method is shown in FIG.
As shown in FIG. 8, the perforated portion 52 is provided on the surface of the tile 51. There are the following two types depending on the depth of the perforated portion 52.

FIG. 19 is a sectional view of a main part showing a fourth example of a conventional repair method. In FIG. 19, the perforated portion 52 is the same as that shown in FIG.
4 and FIG. 15 and an adhesive injector (not shown, designated by reference numeral 56 in FIGS. 14 and 15).
) Is injected. In this case, since the perforated portion 52 has a high probability of communicating with the gap 58 between the tile 51 and the base mortar 55, the adhesive 57 can be efficiently injected into the gap 58. A closed portion 61 is formed at the opening of the perforated portion 52, and the surface thereof is colored in an approximate color of the tile 51.

FIG. 20 is a sectional view of a main part showing a fifth example of a conventional repairing method. In FIG. 20, the perforated portion 52 is formed to a depth of about 60 mm from the surface of the skeleton 54 and is formed in a two-step shape in the same manner as shown in FIGS. 16 and 17, and after the anchor 60 is inserted and fixed, An adhesive 57 is injected, and a cap 62 colored in a color similar to the tile 51 is fitted and sealed in the opening.

[0012]

However, the above-mentioned conventional repair method has the following problems.
First, in any of the repairing methods, while the development and improvement of a perforating device capable of perforating the tile 51 made of a hard porcelain material are progressing, the adhesive 5
7 for infusion tools or attachments are still inadequate. Particularly, when the adhesive 57 is injected within a short time, the injection pressure tends to be large, and the tile 51 is pushed outward from the original fixing position by the large injection pressure, so that the tiles 51 are lifted up. 53 has a problem that it causes interface peeling and loss.

Next, in the conventional repairing method, as shown in FIGS.
In general, the bonding is performed in a state of directly contacting the opening 2, and the injected adhesive 57 overflows from the opening of the perforated portion 52 to contaminate the joints 53 and / or the surface of the tile 51. May be. In such a case, the adhesive 5
It is necessary to wipe off the excess overflowing adhesive 57 after the 7 is injected. However, after the adhesive 57 is solidified, an extremely complicated operation is required, so that the repair cost is extremely increased and the appearance is deteriorated. There is a problem that it may be.

Further, in the conventional repair method, since there is no means for holding the adhesive injector 56 at the portion of the perforated portion 52, the adhesive injector 56 is usually supported manually in the repair work. In addition to the remarkable decrease in workability, there is a problem that the working efficiency is also low and the working time and man-hours are increased. In particular, when a low-pressure injection system is used to increase the filling rate of the adhesive 57, the above-described problem becomes more prominent because the injection of the adhesive 57 takes a long time, and the required amount of the adhesive injector 56 is increased. There is a problem that the number increases and the repair cost rises.
