Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a binning construction method using a hollow noisode.

Parts of building walls, especially exterior walls, may peel off and fall. In order to prevent such falls, a small hole is made from the outside in the part of the outer wall that is raised from the concrete wall of the foundation, and an adhesive such as epoxy resin is injected through the small hole to fill the space. There is a repair method that strengthens the bonding force to the concrete wall surface through.

This repair method is convenient because it is relatively simple and has a great effect, but as mentioned above, when injecting adhesive between the exterior wall and the foundation concrete wall, the injection pressure pushes the exterior wall forward. , the outer wall may collapse. In this case, the outer wall may peel off, so in order to deal with this situation, reinforcing bottles are driven into the wall to be repaired. That is, a method is used in which a hole is drilled from the surface side of the outer wall to the foundation concrete wall surface, adhesive is injected into the hole, and a metal rod is inserted and fixed.

However, in this binning method, when the length of the hole becomes deep, it is difficult to know whether the adhesive has been completely injected to the depth of the hole, and it is also difficult to confirm this. If the adhesive does not sufficiently reach the base of the hole (the part cut into the foundation concrete wall) where the metal rod is to be securely fixed, the purpose of pinning cannot be achieved.

The present invention has been made to solve the above-mentioned conventional disadvantages,
This paper proposes a construction method that can reliably perform pinning when repairing external walls.

Hereinafter, the present invention will be explained with reference to illustrated embodiments. First,
Foundation concrete wall 2 from the surface side of the exterior wall 1 to be repaired
A hole 3 with the required diameter is drilled. Next, a hollow tube 4 is inserted into this hole 3. This hollow tube 4 is made of metal, and a screw 4α is provided on its outer peripheral surface. It is removably attached to the tip of the hole 3, and is inserted deeply into the hole 3 so that the tip almost approaches the inner end of the hole 3. Actually, Noya Eve 4
All you have to do is push it in until the tip of the hole touches the back end of the hole 3, and then pull it back a little. After achieving this state, the adhesive injector 5 is operated to inject an appropriate amount of adhesive (for example, epoxy resin adhesive) from the tip of the pipe 4. Then, the adhesive adheres not only to the inner end of the hole 3 but also to the wall surface of the hole. As mentioned above, a screw 4α is provided on the outer peripheral surface of the pipe 4, and even if the gap between the temporary base plate 4 and the hole 3 is narrow, the adhesive can be applied smoothly using the screw 4α as a passage. This is because it moves to the opening of the hole 3 and sufficiently reaches the opening of the hole 3.

In addition, as shown in FIG. 1, small diameter holes 46 are made in the radial direction at appropriate intervals in the wall of the guide 4.
Sometimes this is done in such a way that the adhesive comes out even from the inside. In this case, the adhesive can be applied efficiently and in a short time, which is particularly effective when the hole is deep.

After applying the adhesive, the armhole 4 is cut 6 at a predetermined location (near the surface of the outer wall 1) and is fixed in the hole 3 as a reinforcing pin. This pinning is performed at multiple locations on the wall to be repaired, and then, as in the past, an adhesive such as epoxy resin is injected into the space 7 to firmly bond the mortar 8 and the foundation concrete wall 2. It is supposed to be done.

At this time, in the case of the present invention, pinning is ensured, so the reinforcing pins will not come off from the concrete wall 2, and the outer wall 1 will not collapse when filling the space with adhesive. Filling work is easy and repair work can be completed completely.

As explained above, according to the pinning method according to the present invention, it is possible to firmly fix the reinforcing pins, and it is possible to prevent accidents that may cause the wall to collapse during repair of the external wall, and its effects “is extremely remarkable.

Claims (1)

[Claims] A small hole is drilled from the surface of the wall to be repaired, dug into the foundation concrete wall surface, and attached to the tip of a hollow pipe adhesive injector with a thread cut on the outer circumferential surface. A binning method using a hollow pipe, which is characterized by inserting it into a hole, injecting adhesive into the hole, and then cutting the hollow mother pipe at a predetermined location and fixing it as it is as pinning.
