DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pinning method and a nozzle for the pinning method.

[0002]

2. Description of the Related Art Conventionally, the purpose of a pinning method is shown in FIG.
(A) As shown in (b), epoxy resin 8 and anchor pin 6
Mortar, tile,
The finishing material 1 such as a stone material is adhered thereto, and is used to prevent the part where the floating has occurred in the finishing material 1 from being peeled or peeled off. In the pinning method, the repaired part is checked with a hammer to check the floating part, the number and arrangement of the anchor pins 6 are determined, the concrete body is drilled in the skeleton 2, and the chips attached to the hole 3 are cleaned with a blower or the like. Then, the nozzle 5 of the injection device is inserted into the hole 3, the epoxy resin 8 is injected into the hole 3, and the anchor pin 6 is inserted into the hole 3 filled with the epoxy resin 8, thereby finishing the surface.

[0003]

However, FIG.
As shown in (a) and (b), the injection of the epoxy resin 8 and the insertion of the anchor pins 6 are separate steps, so that the work time is long and the work efficiency is low. Further, since the diameter of the hole 3 to be formed is determined by the specification and cannot be made large, the diameter of the hole 3 is smaller than the outer diameter of the nozzle 5 of the grease gun 4 (injection device), so that the nozzle 5 does not enter the depth of the hole 3. Therefore, the epoxy resin 8 can be injected only from the vicinity of the entrance of the hole 3, and FIG.
As shown in FIG. 3B, the air 1
There is a problem that 0 is confined and the filling is incomplete and the adhesive strength is reduced. Further, when the anchor pin 6 is inserted, the epoxy resin 8 may be pushed out by the reaction of the trapped air 10 and come out, or the anchor pin 6 may come out, and the insertion must be repeated many times. There is also the problem that it must be complicated.

[0004] Therefore, the present invention is to reduce the pinning construction time for Siding, it is an object to provide a nozzle for pinning method and pinning method to increase the adhesion strength between the skeleton and coverings .

[0005]

According to the first aspect of the present invention,
Holes drilled in the finish and skeleton, clean the hole, generally seen all feed write <br/> pins from the front end hole of the nozzle of the adhesive injection device, inserting the nozzle to the back of the hole, injecting the adhesive from the nozzle from the back of the hole, and the retracting of the nozzle is injected from the nozzle of the pin together with the adhesive, by pulling out the nozzle from the hole, the said finishing material skeleton preparative it is pinning method characterized by comprising repaired with the adhesive and the pin.

According to a second aspect of the present invention, an outer diameter smaller than the diameter of the hole drilled in the finishing material and the skeleton, an inner diameter larger than the outer diameter of the pin, and reaching the inside of the hole are provided.
This is a nozzle for a pinning method, which is set to a length that can be reached .

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a pinning method according to an embodiment of the present invention will be described with reference to FIGS. Holes 3 are drilled in mortar 1 and concrete skeleton 2 as finishing materials, holes 3 are cleaned to prevent poor bonding, and a grease gun 4 as an adhesive injection tool is prepared and attached to grease gun (grout gun) 4. A stainless steel anchor pin 6 is inserted into the nozzle 5, and a cloth waste 7 is placed so as to cover the entrance 3 a of the hole 3. As shown in FIG. The communication shown in FIG.
Insert until it hits the back wall of Ri hole 3. The anchor pin 6 may be entirely inserted into the adhesive 8 in the nozzle 5 or may be partially exposed to the outside. This is because when the nozzle 5 is inserted into the back, the tip of the anchor pin 6 hits the back wall of the hole 3 and is completely inserted into the nozzle 5. Next, an epoxy resin 8 as an adhesive is sequentially injected from the nozzle 5 from the depth of the hole 3 by operating the grease gun 4 a suitable number of times, and the epoxy resin 8 is also filled into the floating portion 9 of the mortar 1 and the concrete frame 2. The state is as shown in FIG. Since the inclined surface of the nozzle 5 is pressed against the inlet 3a, it is possible to prevent the mortar 1 from rising due to the injection pressure of the epoxy resin 8. Further, since the waste 7 closes the entrance 3a of the hole 3, the floating portion (gap) 9 is also filled with the epoxy resin 8.

[0008] Then the anchor pin 6 and the epoxy resin 8 is retracted the nozzle 5 in the direction of arrow B while appropriately times operate grease gun 4 FIG 2 (b) and FIGS. 3 (a) is injected from the nozzle 5 Then, the nozzle 5 is pulled out from the inlet 3a. Since the retraction of the nozzle 5 is also performed by the recoil of the injection, the grease gun 4 does not need to be pulled out so much. Finally, the hole 3 is finished with clogging. In this way, the specified amount of the epoxy resin 8 is filled, as shown in FIG.
The concrete mortar 2 is repaired with the anchor pins 6 and the epoxy resin 8 so that the mortar 1 can be prevented from peeling off or coming off due to the floating of the mortar 1. Further, since the filling of the anchor pins 6 and the epoxy resin 8 can be performed simultaneously in one step, the operation time can be reduced to half or less. Furthermore, since the epoxy resin 8 can be filled from the inside of the hole 3, it is possible to prevent the air from being trapped in the inside of the hole 3 by the epoxy resin 8, and the bonding strength is dramatically increased.

[0009] pinning method for nozzle 5 as shown in FIG. 4 (a) ~ (d) is an improvement of the nozzle of FIG. 9 (a), cutting the small diameter distal end portion of the nozzle body 50,
A groove 50a is provided in the cut end, the short pipe 51 is inserted into the groove 50a, and the short pipe 51 is connected by caulking with the nozzle body 50. A commercially available nozzle can be used, and the nozzle 5 can be formed by simple processing. These can be integrally formed. Short pipe 51
Is tapered to increase the injection cross section. For this reason, the anchor pin 6 can be easily inserted, the epoxy resin 8 can be quickly filled, and the waste 7 can be easily pierced, so that the workability is excellent. The short pipe 51 is longer than the length of the anchor pin 6, has an outer diameter 51 a smaller than the diameter of the hole 3, and has an inner diameter 51 b larger than the outer diameter of the anchor pin 6.

The diameter of the hole 50e of the nozzle body 50 gradually decreases from the base end to the tip end, and the inner diameter 50b of the base end is made larger than the inner diameter 51b of the short pipe 51 so that the epoxy resin 8 has been facilitated. Further, the inner diameter 50c on the distal end side is smaller than the inner diameter 51b of the short pipe 51, and is smaller than the outer diameter of the anchor pin 6. Therefore, the inner diameter 50c prevents the anchor pin 6 from entering the nozzle body 50, so that the anchor pin 6 can be fixed at an appropriate position of the hole 3. A male screw 50f is provided at the base end of the nozzle body 50,
The grease gun 4 can be screwed into the outlet. The outside of the tip of the nozzle body 50 is a tapered cylindrical surface 50d, which can be brought into contact with the inlet 3a at an appropriate position. As shown in FIG. 4E, the anchor pin 6 is provided with a male screw on the entire outer periphery thereof, and has a shorter length than the short pipe 51. For example, the size of the anchor pin is 4φ and the length is 50 mm, the hole 3 is 7φ and the length is 60 mm (the perforation length of the concrete frame 2 is about 30 mm),
The short pipe 51 has an outer diameter of 6φ and an inner diameter of 5φ and a length of 60 mm.
