Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a connector for connecting house constituent members such as columns and beams.

[0002]

[Prior art]

 Conventionally, as a connecting tool for connecting house components such as columns and beams, a rod is welded to the tip of a fastening plate that is fixed to the column, and a male screw is formed at the tip of this rod. A coupling tool has been proposed (generally referred to as a battledore bolt).

In this battledore bolt, a rod is inserted into, for example, a beam, a fastening plate is fastened to a column with nails, and a nut is screwed to a male screw portion of the rod to connect the column and the beam. It is a thing.

[0004]

[Problems to be solved by the device]

 Initially, the battledore bolts are firmly stopped, but when trees dry each year and the beams shrink, for example, a gap is created between the nuts and beams, resulting in poor nut tightening force. Therefore, there is a problem that it is easily affected by wind, snow, earthquakes, etc., the rate of inclination of the building increases, and the building itself does not last long.

The present invention has a technical object to provide a battledore bolt that solves the above problems.

[0006]

[Means for Solving the Problems]

 The gist of the present invention will be described with reference to the accompanying drawings.

A connecting tool for connecting house constituent members such as pillars 1 and beams 3, which is provided with a fastening body 2 which is fastened and fixed to one house constituting member, and a support body 9 is erected on the fastening body 2. The rod body 5 having the male screw portion 12 at the tip and the bearing 8 at the base end is loosely fitted to the support body 9, and the female screw body 7 is attached to the male screw portion 12 of the rod body 5. A connector according to the invention, which is constructed by screwing and fitting a ridge 6 on the base end of the rod body 5, and receiving both ends of the ridge 6 by the support 8 and the support 9. Is.

[0008]

[Action]

 The rod body 5 is inserted into one of the house components so that the male screw portion 12 of the rod body 5 is in a protruding state, and the fastening body 2 is fastened to the other house component member, and the base end of the rod body 5 is attached. The female screw body 7 is screwed onto the male screw portion 12 against the fitted rod 6 to connect the members constituting both houses.

Even if a house component is dried and a gap is created between one house component and the female screw body 7, the restoring force of the spring 6 that is received by the support body 8 and the support body 9. The rod body 5 slides with respect to the support body 9 to eliminate the above-mentioned gap between the house constituting member and the female screw body 7, and the tightening of both house constituting members is not loosened.

Therefore, both house component members are always moved by a constant force by the product of the present invention.

When the house constituent member expands, the spring 6 which is received by the support member 8 and the support member 9 further contracts, so that the female screw member 7 does not bite into the house constituent member.

Since the rod 5 is inserted into the support 9 in a loose state, there is no problem even if the rod 5 is slightly inclined with respect to the house constituting member.

[0013]

【Example】

 The drawings illustrate one embodiment of the present invention and are described below.

Several nail holes 10 and bolt holes 11 are bored in the rectangular plate-shaped fastening body 2, and a plate-shaped support body 9 is welded to the tip of the fastening body 2 in an upright state. .

A round rod-shaped rod body 5 having a male screw portion 12 at the tip and a plate-shaped support body 8 at the base end is loosely fitted to the support body 9. The support 8 is formed in a square plate shape so as to perform a rotation preventing function.

A nut as a female screw body 7 is screwed onto the male screw portion 12 of the rod body 5 via a seat plate 13.

A ridge 6 is fitted on the base end of the rod body 5, and the ridge 6 is received by the support 8 and the support 9.

In the figure, reference numeral 14 is a retaining plate, reference numerals 1 and 3 are pillars and beams as house components, reference numeral 4 is a through hole formed in the beam 3, reference numeral 15 is a nail, and reference numeral 16 is a bolt. .

Since the present embodiment has the above-mentioned configuration, the rod 5 is inserted into the through hole 4 of the beam 3, and the fastening body 2 is fastened and fixed to the pillar 1 with the nails 15 and the bolts 16. When the nut is screwed onto the male screw portion 12 and tightened, the pillar 1 and the beam 3 are firmly connected. Then, for example, even if the beam 3 is contracted, the elasticity of the spring 6 does not loosen the fastening between the column 1 and the beam 3.

[0020]

[Effect of device]

 Since the present invention is configured as described above, the elasticity of the spring acts according to the contraction of the pillar or beam, the tightening of the house constituent members does not become loose, and the gap does not occur between the house constituent members. Is prevented, so that the building is not squeaked, the walls are not cracked, and no excessive force is exerted on the building, and therefore an excellent battledore that can provide a durable and long-lasting building. It becomes a bolt.
