DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention is applicable to an assembled unit frame panel, and makes the installation of an embedded part for a building and the related work such as the disassembly or post-processing step of the frame panel quicker and simpler. The present invention relates to an auxiliary fixture for mounting an embedded component, which can be carried out in the field, and an embedded component mounting method using the auxiliary fixture.

[0002]

2. Description of the Related Art In general, building frame panels are classified into metal foam frame panels and traditional wooden frame panels.
In these frame panels, systematization in design and use, that is, assembly as a unit, is required in order to increase the construction efficiency of the standardized collective building. Wooden frame panels are no exception, and companies are trying to reduce construction costs by saving labor in assembling and dismantling by unitizing and improving the rate of repeated use of frame panels.

[0003] As a conventional embedded part for building, for example, Japanese Patent Publication No. 103,491 (Taiwan), FIG.
The embedded nut structure as shown in FIG. The embedding nut structure mainly includes a fixed protective sleeve 10. First, as shown in FIG. 6, a pair of nails 11,
Then, the base 20 having the nut structure is tightly fitted into the sleeve hole 10b of the fixed protective sleeve 10. Thereafter, as shown in FIG. 7, the assembled component is placed at a pre-marked position on the wooden frame panel, and
Then, the pair of nails 11 and 12 are driven into the inner surface of the wooden frame panel M and fixed. Then, drive the mortar and fix the assembled parts together in the concrete wall,
A screw hole 21 embedded in a wall surface is formed, and is used for screwing various members such as a hook for a pipe material.

The embedded nut fixed to the above-mentioned conventional wooden frame panel has a problem that complicated work is required in mounting work and post-processing steps. First, after the wooden frame panel M is removed, the entire embedding nut is buried in the concrete wall surface, and only the tips of the pair of nails 11 and 12 are exposed outside the concrete wall surface. The wall painting work will not proceed unless the cut end is cut. Also, every time a mounting nut is installed, a new mounting position of the mounting nut on the wooden frame panel must be marked. In addition, a plurality of mounting nuts must each be nailed to the wooden frame panel.

On the other hand, conventionally, when mounting an embedding nut on a metal foam frame panel assembled into an assembled unit, a through hole is previously penetrated at the embedding position of the embedding nut, and the through hole is penetrated from outside the metal foam. The embedded nut is fixed to the inside of the metal form frame panel by screwing the embedded nut to the inserted bolt. Then, after inserting the mortar and embedding the embedded nut in the concrete structure, the bolt is extracted from the screw hole of the embedded nut, and the frame panel disassembling operation proceeds.

In such a mounting method of the embedding nut, it is not necessary to repeat the work of marking the embedding position, but every time the metal foam frame panel is disassembled, all the bolts are always screwed into the screw holes of the embedding nut. This is very inconvenient because it must be reliably extracted from For example, when the number of embedded nuts is large, if the bolt is inadvertently forgotten to remove even one place, the embedded nut is extracted from the already solidified concrete structure when the metal foam frame panel is disassembled. Further, when mounting the embedding nut to the metal foam frame panel, a plurality of bolts must be screwed, respectively, which takes much time and effort.
