DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to relates to how to manufacture the outer wall repair anchor pin of the building.

[0002]

2. Description of the Related Art In general, in mortar outer wall repair work for preventing the risk that the mortar outer wall of a building rises and expands over time from its concrete frame and expands (so-called swelling phenomenon), and furthermore, the mortar outer wall is prevented from peeling off. In order to mechanically fix the anchor to the concrete frame, various cylindrical anchor pins, each of which has an expansion plug inserted and set inside the hollow, are used.

[0003] In other words, in advance of its use, into the inside of the prepared hole drilled from the outer wall of the mortar to the concrete frame,
First, the anchor pin is embedded, and the expanding plug is hit to expand the anchor pin from the front end side, so that the anchor pin is bitten and fixed to the concrete frame.

[0004] Next, an adhesive such as a wet-curable epoxy resin is injected into the hollow of the anchor pin, and the adhesive is injected into the hollow of the anchor pin from the hollow of the anchor pin to the lower hole or the outer wall of the mortar by injection pressure. By flowing and spreading to the gap between the concrete skeleton (the floating part of the outer wall) and the synergistic effect of the adhesive force and the biting force of the anchor pin, the mortar outer wall is prevented from rising and expanding or coming off. Has become.

Among the various types of anchor pins into which an adhesive can be injected, the only one shown in FIGS. 53 to 57 is the only one that is practically used as a product finished from a metal plate into a substantially cylindrical shape. is there.

This conventional anchor pin is formed by pressing a metal plate into a semi-cylindrical shape, and a pair of identical half halves (1L) and (1R) facing each other, and both half halves (1R).
L) An injection port cylinder (2) for a synthetic resin material adhesively welded and integrated to cover the outer peripheral surface and the inner peripheral surface at the base end of (1R). The two halves (1L) and (1R) are assembled and fixed in an overall cylindrical shape via (2).

In addition, the base end side of the inlet cylinder (2) is smoothly curved as an outwardly expanding conical flange portion (2a) adapted to the base end sides of the two halves (1L) (1R). On the other hand, the distal end side of the inner peripheral surface of the injection port cylinder (2) also serves as a stop step portion (2b) to prevent the expansion plug (3) from falling off toward the base end side of the anchor pin. I have.

[0008] (4) is a concave and convex strip for biting the concrete body (C) corrugated at the tip of both halves (1L) and (1R), and (5) is also a double halved body (1L). )
The expanding recess notched at a predetermined length (L) along the crevice while being located at the tip of (1R), (6) remaining both halves (1L) and (1R) It is needless to say that there are a plurality of outflow holes for adhesive distributed in the middle portion, and one pair of the outflow holes faces each other.

[0009]

However, in the anchor pin having the above structure, the two halves (1L) and (1R) are assembled as two independent pieces by an injection port cylinder (2) for a synthetic resin adhesive. Since it is an integrated product, a part of the injection port cylinder (2) has a through-hole (1L) (1R) facing the base end thereof, as is apparent from FIG. 7), even if the two halves (1L) and (1R) are forcibly expanded from the distal end side by hitting the expansion plug (3), even if the insertion and welding state is fixed and maintained.
Cracks are easily formed in the inlet cylinder (2) from the cracks, and it is inevitable that the durability of the anchor pin is reduced.

Further, the base end side of the two half-pieces (1L) and (1R) integrally attached to the injection port cylinder (2) has a conical shape having a smooth outer spread as a flange portion (2a). 57, and the flange portion (2a) is embedded and fixed in a state of being immersed into the prepared hole (H) from the surface of the mortar outer wall (M), as is apparent from the use state of FIG. It is difficult for the flange (2a) to seal the backflow and overflow of the adhesive (B) to the base end along the prepared hole (H) due to the injection pressure.
Moreover, it is impossible at all to prevent the mortar outer wall (M) from being deformed so as to rise and expand by the flange portion (2a).

As a countermeasure, the flange portion (2)
It is conceivable that a) protrudes from the base end side of the injection port cylinder (2) at a large angle and substantially at a right angle. However, in this case, the injection pressure of the adhesive (B) is too high, or the mortar outer wall (M) If the material is greatly deformed or deformed, there is no danger that the injection port cylinder (2) made of a synthetic resin material that cannot withstand the tensile force may fall out of the two halves (1L) and (1R).

Further, the method of manufacturing the anchor pin is not limited to the sheet metal press working of the two halves (1L) and (1R), and the processed facing pair is continuously and accurately combined to form the injection port cylinder (2). )) Into the molding die, and by pouring a synthetic resin material into the die, simultaneously with the molding and hardening of the injection port cylinder (2), the two halves (1L)
Since (1R) must be fixedly integrated, it is not possible to automate the production process, and it is not possible to exert the effect of mass-producing such a large amount of anchor pins.

[0013]
