  However, in the above technique, a pilot hole is made in the base material, a curable adhesive is injected, and the anchor material, for example, the embedded plug is tilted during the curing, or the adhesive is cured and lifted, and the center line is shifted. There is a problem that the trunk edge cannot be fixed at an appropriate position. The present invention solves such a problem, and the plug fitted in the pilot hole is maintained in a predetermined position until the curable adhesive is cured, and the embedded plug that can fix the trunk edge in an appropriate position is applied. The problem is to provide a structure.

In order to solve the above problems, the present invention takes the following technical means. That is, according to the reference example of the present invention, a curable adhesive is injected into a pilot hole provided in a base material, and a stopper is inserted. There is provided a construction structure of an embedded plug in which the stopper is tapered and all or part of the periphery of the upper surface of the stopper is hooked in contact with the opening edge of the pilot hole. . The plug is preferably made of wood or synthetic resin.

  A plug having an inverted frustoconical shape is preferred as the plug whose entire periphery around the upper surface of the plug is in contact with the opening edge of the pilot hole. Furthermore, it is preferable that the trunk edge receiving portion is extended on the upper surface of the inverted truncated cone shape. Further, as the plug whose part around the top surface of the plug is in contact with the opening edge of the pilot hole tightly, a plug having an inverted truncated pyramid shape is preferable. Furthermore, it is preferable that the trunk edge receiving portion is extended on the upper surface of the inverted truncated pyramid shape. The trunk edge receiving portion covers the periphery of the pilot hole and has a pedestal shape for receiving the trunk edge. In particular, a circular pedestal or a rectangular pedestal is preferably used.

According to the present invention, a plug is inserted by injecting a curable adhesive into a pilot hole provided in the base material, and the construction structure of the embedded plug in which the trunk edge is fixed to the plug after the adhesive is cured, There is provided a construction structure for an embedded plug, in which the plug is a prism, and the edge of the prism is engaged with the inner peripheral surface of the pilot hole after being fitted into the pilot hole. As the prism, a quadrangular column, a pentagonal column, a hexagonal column or the like is preferably used. Furthermore, it is preferable that a trunk edge receiving portion extends on the upper surface of the prism. The trunk edge receiving portion covers the periphery of the pilot hole and has a pedestal shape for receiving the trunk edge, and a circular pedestal and a rectangular pedestal are particularly preferably used.

Therefore, it is possible to keep the barrel edge in an appropriate position by keeping the predetermined position until the curable adhesive poured into the pilot hole is cured in advance.

  Since the stopper has an inverted truncated cone shape or an inverted truncated pyramid shape, the upper surface of the stopper is formed slightly larger than the opening edge of the pilot hole and lightly tapped into the pilot hole to fit the upper surface of the stopper. All or part of the circumferential portion can be tightly brought into contact with the opening edge and hooked in place. Further, since the trunk edge receiving portion extends on the top surface of the stopper, the trunk edge placed on the trunk edge receiving portion is firmly fixed to the embedded stopper by a fixing means such as a screw.

The present invention is as described above, and in particular, since the stopper is a prism, and a prism formed slightly larger than the pilot hole is lightly tapped and inserted, the edge of the prism is the inner peripheral surface of the pilot hole. And can be hooked in place. Further, since the trunk edge receiving portion extends on the top surface of the stopper, the trunk edge placed on the trunk edge receiving portion is firmly fixed to the embedded stopper by a fixing means such as a screw.
