CONSTITUTION:A fixture for a structural member is formed of a drive body 1 to be driven into the structural member, and one or plural driving lock bodies 2 placed inside the drive body 1, and provided with a communicating hole 3 from which the tip of the driving lock body 2 is protruded in the curved state around the tip of the drive body 1.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hollow structure material such as a plaster board, an ALC board, a wood, a chip board, a foamed resin board, a glass wool board, a rock wool board, or the like, which can be nailed in a building structure or a soft base. The present invention relates to a fixture for a structural member used for fixing another structural member to a material.

[0002]

2. Description of the Related Art In the case of fixing other structural members such as wood and plastic to a base material such as a gypsum board, it has been conventionally fixed to the base with adhesives, bolts, screws, nails of various shapes and the like. Further, as the anchor bolts to the ALC plate or the like, there have been used split tip type bolts that are opened by driving and bolts with embedded holes.

[0003]

With respect to these various types of conventional fixtures, it takes time and labor in addition to the work of drilling and the need for tools such as drills. In addition, in the case of simple ones, the lack of strength was inevitable.

[0004]

Therefore, a driving body 1 for a structural member and one or a plurality of driving locking bodies 2 inside the driving body 1 are provided. Near the tip,
Communication hole 3 in which the tip of the driving locking body 2 projects while curving
We have developed a fixture for structural members, which is characterized in that Here, the driving main body 1 is a pipe material, the inside thereof is the insertion hole 4 of the driving locking body 2, the tip is the communication tip 3 with the cutting tip 5 and the notch in the vicinity thereof, and the base is the threaded portion 6. I set up something. Also, when manufacturing a large-sized fixture using a rod, the driving body 1 is a rod, and the inside is the insertion hole 4 of the one or more driving locking bodies 2 near the tip of the core. Each through hole 4
To the outside, and the one having the threaded portion 6 formed on the base portion.

[0005]

With this structure, when the driving body 1 is driven until it reaches the soft material, and the driving locking body 2 is inserted into the hole of the driving body 1 and driven, The nail tip of the stopper 2 reaches the tip of the insertion hole 4 of the driving body 1 and goes out from the communication hole 3 provided in the driving body 1 near the tip to the outside to form a hook-shaped protrusion 2a, which is soft. It projects into the base material.

The driving body 1 can be easily manufactured from a pipe or a rod material, and particularly in the case of a pipe, it is simple. The rod is particularly useful for use as a large anchor bolt, a plurality of locking protrusions serve as a strong anchor, and a thick bolt can be freely manufactured. The combination of the driving body 1 and the driving locking body 2 eliminates the need to make holes in the structure, and can be used as a simple nail if necessary, and male or female threads can be freely selected, so a wide range of combinations can be used. It is possible.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows a fastener according to a first embodiment of the present invention, which is a driving body 1 for a structural member and one or a plurality of driving locking bodies 2 inside the driving body 1. And a communication hole 3 is provided near the tip of the driving body 1 so that the tip of the driving locking body 2 projects while curving. Here, the driving main body 1 is a pipe material, the inside thereof is the insertion hole 4 of the driving locking body 2, the tip is the communication tip 3 with the cutting tip 5 and the notch in the vicinity thereof, and the base is the screw portion 6. is there. Since it is a pipe material, the communication hole 3 is originally formed.
The pointed portion 5 can be easily formed by pressing. Driving locking body 2
Is a simple headless nail, and when the driving body 1 is driven into the structural material as shown in FIG. 5, and then the driving locking body 2 is inserted into the communication hole 3 and driven, the tip is from the communication hole 3. It bends into the structural material and projects into a hook-shaped projection 2a. The base portion of the pipe is threaded to form a thread portion 6, and a washer 7 and a nut 8 are used to fix the furring strip wood to the ALC plate, for example.

FIG. 2 is a perspective view of a fixture according to the second embodiment of the present invention. In this example, the driving body 1 is formed of a thick bar material,
This is a large anchor bolt having three insertion holes 4 and communication holes 3 drilled therein and threaded into the base to provide a threaded portion 6. The driving locking body 2 shown in FIG. 1 is used, and other usages are in accordance with the above-described first embodiment.

FIG. 3 is a perspective view of a fixing tool according to a third embodiment of the present invention, in which the driving body 1 has a single insertion hole 4 formed from a relatively thick pipe, and has two left and right directions near its tip. Through hole 3
And the base portion has the flange portion 9 formed by burring. As shown in the right side of FIG. 3, the driving locking body 2 has a notch 10 formed at the tip thereof. Therefore, when the driving locking body 2 is inserted into the insertion hole 4 of the driving main body 1 and is driven while searching for the communication hole 3, As shown in the left part of FIG. 3, two hook-shaped protrusions 2a on the left and right are formed by dividing the fork into a strong anchor.

FIG. 4 shows a fixture according to a fourth embodiment of the present invention, in which the driving body 1 is formed from a triangular pipe in the same manner as in FIG. 3, and three driving holes are inserted into the insertion holes 4 therein. This is a type in which the locking body 2 is driven at the same time. Instead of the three driving locking bodies 2, three notches may be formed at one end to form three hook-shaped protrusions 2a while being divided into three forks. This is used when the strength is insufficient with one hook-shaped protrusion 2a in FIG. 1 or two hook-shaped protrusions 2a in FIG.

FIG. 5 is a sectional view showing a fixing tool according to a fifth embodiment of the present invention, showing a state in which the structural member has been driven. In any of the above cases, the usage is as shown in FIG. 5, but the example of FIG. 5 is one in which the flange portion 9 and the thread portion 11 of the inner surface bolt are formed instead of the outer surface bolt thread portion 6 of FIG. is there. In this case, the driving locking body 2 is driven into the insertion hole 4 and the wall plate 14 is fixed to the ALC plate 13 as a structural material by screwing the bolt 12 into the screw portion 11. If a triangular screw is used instead of the bolt 12, the wall plate 14
It can be fixed flush with the surface of. In addition, various shapes applying the idea of the present invention are possible.

[0012]

Since the fixture for the structural member of the present invention has the above-mentioned structure, it is easy to manufacture, the construction is simple, and the fixing force is strong, and even if it is an ALC plate, it is impossible. If you try to pull out the fixture, it will cause structural damage, so you can provide a highly reliable product.
