DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an anchor closing member for closing an insertion hole of an anchor member fixedly used in a concrete structure or the like and an opening formed in a wall repairing portion. About.

[0002]

2. Description of the Related Art In consideration of a situation in which an exterior material such as a tile falls due to mortar peeling or cracks in the interior, a wall repair method for fixing an exterior material directly to a concrete foundation with an anchor member has recently been implemented.

An anchor member disclosed in Japanese Patent Application Laid-Open No. 4-128473 is suitable for such repair.

[0004] This is achieved by locking a flange of an anchor body to a bottom surface of an opening formed in an exterior material, driving a pin into the anchor body, expanding and fixing a tip end of the anchor body, and then using epoxy resin or the like. A sealing material is injected from the rear end of the anchor body to spread inside and outside the anchor, and finally the opening of the hole is filled with a resin or the like or a sealing member is applied and fixed with an adhesive, and the surface of the exterior material is fixed. It is a construction method that is almost the same color as.

However, in such a repairing method, even if the opening is sealed immediately after the injection, the sealing material may be damaged or pushed back due to the return pressure of the sealing material, causing a reduction in work efficiency. .

[0006] Also, holes drilled in concrete etc.
It is desirable to be bored perpendicular to the surface of the exterior material, but in practice it is often inclined, and in this case, it is extremely difficult to obtain a flush state between the surface of the closing member and the surface of the exterior material. There was also a problem that it is.

Therefore, the present applicant has disclosed in Japanese Patent Laid-Open No.
No. 10 proposes an anchor member that solves these problems.

That is, after the anchor body is inserted into a communication hole formed from an exterior material such as a tile to a mortar or a concrete base, a tip portion is expanded by driving a pin, and the anchor body is fixed to the communication hole. After the sealing material is injected from the rear end of the anchor main body, the closing member is immediately driven into the rear end of the anchor main body with a hammer or the like and pressed in.

[0009] Even when the axis of the communication hole formed in concrete or the like is slightly displaced from the vertical line to the surface of the exterior material, the holding function of the arbitrary holding projection allows the closing member to be closed. The axis is corrected so as to coincide with a vertical line to the surface of the exterior material, and the flange portion is flush with the surface of the exterior material.

[0010]

However, in the above-mentioned conventional repair method, when the axis of the communication hole formed over the concrete base is within a range slightly inclined with respect to a vertical line to the surface of the exterior material. In this case, the axis of the closing member is aligned by the action of the arbitrary holding projection, and the flange portion of the closing member is corrected so as to be flush with the surface of the exterior material.

For this reason, if the axis of the communication hole formed over the concrete base is tilted more than necessary, the tolerance of the axis alignment of the closing member due to the action of the arbitrary holding projections will be exceeded. , Cannot correct the flange part to be flush with the surface of the exterior material,
There was a problem that the appearance was spoiled.

The present invention has been made in view of such circumstances, and even when the axis of the communication hole is tilted more than necessary, the flange portion of the closing member is kept in contact with the surface of the exterior material. An object of the present invention is to provide an anchor closing member that can be easily corrected to be flush.
