Description

  The present invention is, for example, a U-shaped staple used for fixing an electric wire in electric wiring, or a nail for holding a mounting body such as a saddle or a watt-hour meter box on an ALC surface, and a calendar, a bulletin board, etc. The present invention relates to a fixture such as a hanging tool having a function.

Conventionally, in piping work such as PVC pipes and air conditioners on the ALC or gypsum board surface, when using normal nails, the ALC or gypsum board surface is used to fix electric wires such as VVF cables. When it is driven in, the metal of the nail body is driven in while destroying the material in the ALC or gypsum board, so it does not adhere to the material in the ALC or gypsum board, and the pullout strength is weak, so it is durable It is inferior to.
Therefore, the auxiliary material is used for screwing, but these operations are time consuming and inefficient.

In addition, in a staple formed with a U-shaped metal wire that uses an electric wire such as a VVF cable for electrical wiring for wiring work such as a wall surface, a wall such as ALC (lightweight cellular concrete) and gypsum board, ceiling, etc. When fixing the electric wire such as VVF cable (vinyl insulation vinyl sheath cable flat type) by driving staples on the surface, when the head of the staple is driven with a hammer or the like, the metal that is both legs of the staples is the ALC and the material in the gypsum board When broken and driven in, both legs do not adhere to the material in the gypsum board, the fastening force is weak, and the durability often causes a drop due to the weight of the VVF cable.
Also, the wiring work on the ceiling surface is not suitable because the staples often come off even during the fastening work.
Furthermore, screwing a saddle or the like used to fix the wiring is inefficient and laborious.

  In addition, in ALC and hanging tools that hang bulletin boards, hangers, picture frames, etc. on the plasterboard surface, the stopper of the hanging device is fixed in a needle shape or screw shape, but the attachment is weak and it gradually falls off. It is.

Therefore, there is a nail with an adhesive layer that is uniformly coated with colored minicapsules filled with adhesive on the inside and body of the head. There is a nail that breaks and the adhesive flows out, enters while increasing the lubrication effect, and then hardens and adheres to increase the pulling resistance (see, for example, Patent Document 1).

  Further, as a measure for improving the stapling of the gypsum board wiring work, there is a method in which a plurality of barb portions are provided in the staple-like portion of the staple (see, for example, Patent Document 2).

  In addition, the gypsum board article has been improved in strength so that it does not cross out in the gypsum board by inserting three pins into the hanging part to be fixed to the gypsum board surface and a circular base in an oblique direction. There is a mounting base for a fixture (see, for example, Patent Document 3).

Further, a stepped portion having a small diameter is provided on the shaft 4 of the nail having the bolt head, and a sleeve is placed on the stepped portion and is crimped to form an ALC nail. A rib in the axial direction is provided on the stepped portion of the nail, and a rib in the circumferential direction is provided on the sleeve. When an ALC nail is driven into the ALC and rotated by a driver, the sleeve 3 is expanded in diameter by an axial rib of the nail and pressed against the ALC, and the ALC nail is fixed (for example, see Patent Document 4). .

Also, the nail surface is coated with a paint mixed with hard particles with good adhesion to the paint, and the nail body surface is formed with discontinuous protrusions with hard particles. There are nails that improve (see, for example, Patent Document 5).

  However, in the device of Patent Literature 1, when it is driven into ALC or gypsum board, it is driven while having a lubricating effect, and it takes some time until a cured adhesive effect is generated. Therefore, in the installation work on the ceiling surface, the installation work on the wall surface is unsuitable because it may fall off due to the weight, and when cured in contact with the material in ALC or gypsum board, It is unsuitable for ALC or gypsum board because of its weak adhesion to the body of ALC or gypsum board and nail.

Moreover, vulnerable the wire when retains the wires striking the invention of Patent Document 2, unit price becomes expensive by the complexity of further structure.

The invention of Patent Document 3 can be used only for a gypsum board, but cannot be used for an ALC or a lightweight block.

  The invention of Patent Document 4 can be used for ALC, but is not suitable for the use of gypsum board.

The invention of Patent Document 5 is effective for wood or the like, but when it is driven into the ALC or gypsum board by a plurality of hard particle projections on the surface of the nail body, the internal material is destroyed, and the nail It is difficult to come into close contact with the trunk, and the nail trunk does not have elasticity, so that it is easy to come off. Therefore, it is not suitable for ALC or gypsum board material.

Accordingly, the present invention has been made to solve the above problems, and in consideration of this, a metal body having a head and a synthetic resin adhesive and metal powder having elasticity in a body formed sharply toward the tip are mixed. This is a fixing tool that is coated with the fixing member and used as a nail.

Therefore, the present invention provides a nail that can be easily fixed to various attachments by using a nail on the ALC or gypsum board surface, and that can further increase and maintain the fixing force.

In addition, the fixing device has an increased resistance to fastening, in which a fixing member in which a synthetic resin adhesive and metal powder are mixed is applied to the metal wire portions of both legs of the wiring staple.
Alternatively, it is a fixing tool in which a synthetic resin adhesive and a thread are wound around the metal wire portions of both the leg portions of the staple and applied to form a staple.
Therefore, if staples are used in the electrical wiring work, it is easy to fix the wires such as VVF on the ALC surface and the gypsum board surface, and the fixing can be maintained with a high degree of fastening. It provides tools.

Also, a hanging part is provided at at least one end of the flat head of the staple, and a fixing member mixed with a synthetic resin adhesive and metal powder is applied to both legs of the staple, or a synthetic resin. It is a fixing tool which is a hanging tool coated with a system adhesive and a thread.
Therefore, we provide a fixture that can hang various objects by driving the hanging tool into the ALC or gypsum board and attaching the hanging tool to obtain a strong fastening force on the ALC surface or gypsum board surface. To do.
