[Detailed Description of the Invention] (Industrial field of application) The present invention relates to a pin for injecting an adhesive agent into a wall surface, which is used for injecting an adhesive agent between a concrete wall and a mortar layer formed on this wall. Regarding

However, after solidification of the concrete wall, the adhesive strength of the mortar layer formed on the concrete wall to the concrete wall surface cannot be put to practical use only by the adhesive strength of the mortar itself, so the joint surface between them (hereinafter referred to as the interlayer) A so-called pinning method is used to increase the peel strength by injecting an adhesive.

This pinning method waits for temporary solidification of the mortar layer on the concrete wall, takes an appropriate range (area), and pierces a large number of small holes from the surface of the mortar layer to the concrete wall. An adhesive is injected through the layer to penetrate between layers, and after the adhesive is injected, a stop pin is inserted into the small hole and the adhesive remaining in the small hole is solidified and embedded.

(Problems to be Solved by the Invention) The injection of the adhesive in the above-described conventional pinning method is performed by directly connecting the adhesive injection device to the small hole opening on the surface of the mortar layer.

Considering the interpenetrating action of the adhesive at this time, the pressure from the injector side is applied to the small holes in a state where the adhesive is filled, and during the short time when this pressure reaches the maximum value. The adhesive penetrates into the layers.

Therefore, according to the conventional pinning method described above, the adhesive that fills the small holes at the time of injecting the adhesive forms one adhesive pillar, and the adhesive pillar is bonded under the pressure applied to the adhesive pillar. Since the adhesive shunts from around the agent column and permeates between layers, the permeation range of the adhesive between layers (not uniform around the small holes) depends on the pressure applied to one adhesive column as a whole. It is decided.

In addition, since the pin embedded in the small hole is to be solidified by being inserted into the adhesive remaining in the small hole after the adhesive is injected, when the adhesive is solidified, air bubbles or the like are generated on the pin surface. Occurrence occurs and the adhesion strength with the pore wall decreases.

The present invention has been made in view of the above-mentioned point, and a pin embedded in a small hole after the adhesive is injected is used for injecting the adhesive to expand the penetration range of the adhesive between the layers around the small hole. At the same time, it is an object of the present invention to provide a pin for injecting an adhesive agent into a wall surface in which the solidification strength of the pin left in the small hole is also increased and the peel strength of the mortar layer is remarkably improved.

(1) For the small holes reaching the concrete wall from the surface of the mortar layer, the adhesive is injected through the mouthpiece that presses the annular packing on the mouth surface of the small holes and adheres hermetically. Therefore, compared to the conventional construction method in which the injector is directly joined to the small hole mouth, there is no leakage of the injection pressure and the high pressure is maintained to enable reliable injection.

(2) The adhesive flowing in the gap between the spiral groove on the peripheral surface of the pin body and the wall of the small hole in the small hole is spiral and forms a plurality of adhesive flow strips. Since the adhesive penetrates into the layers from the flow strips, a uniform high-pressure injection pressure is applied to each adhesive flow strip from the injector side to expand the permeation range centering on the small holes. .

(3) After the adhesive is injected, even if the adhesive injector is removed from the mouthpiece, the adhesive remaining between the spiral groove on the peripheral surface of the pin body and the small hole wall in the small hole flows backward to the mouthpiece side. Shows high flow resistance, and the pin hole insertion part of the mouthpiece is fitted in the small hole mouth portion, and the gap between the injection hole in the mouthpiece and the spiral groove on the peripheral surface of the pin body is small, Since it is difficult for the adhesive to leak to the outside of the base, the adhesive remaining in the small holes solidifies with some pressure during injection, and no bubbles are generated on the peripheral surface of the pin body. Greatly increases the peel strength of the mortar layer.
