Since the length of the turnbuckle can be easily adjusted by using the turnbuckle body as in the configuration of Patent Document 1, this turnbuckle body is provided in a general turnbuckle.

However, when such a turnbuckle body is used, the operability is improved when the adjustment range of the turnbuckle length is large, but the turnbuckle body is too large when it is installed in a narrow range or when the adjustment range is small. In some cases it was difficult to use.

Therefore, a turnbuckle that does not use a turnbuckle body, such as the turnbuckle of Patent Document 2, has been proposed. However, in the configuration of Patent Document 2, there is a problem in the work of adjusting the turnbuckle length. That is, in order to adjust the length of the turnbuckle in this configuration, the length of the long bolt screwed to the end of the battledore is changed and adjusted.

Therefore, after fixing the battledore to the building, it is necessary to rotate the long bolt itself in order to adjust the turnbuckle length. Therefore, there remains a problem that the length adjustment work performed by operating this long bolt becomes difficult.

Therefore, the present invention has been devised to solve the above-mentioned problems, and an object of the present invention is to provide a turnbuckle brace that facilitates length adjustment without using a conventional turnbuckle body.

In order to achieve the above object, the first means of the present invention is to use a turnbuckle brace between a pair of connecting bodies 20 arranged on both sides of the brace 10 and between one connecting body 20 and the end of the brace 10. The length adjusting body 30 is composed of an intervening length adjusting body 30, and the length adjusting body 30 is a connecting body of a main body 31 having a columnar shape, a female screw portion 32 formed on the brace 10 side of the main body 31, and one of the main body 31. and a bolt portion 33 formed between the 20 and configured to screw with left-hand thread the bolt portion 33 on one of the connector 20, part of the outer periphery of the thicker body 31 than the diameter of the external thread of the brace 10 Alternatively, the nut shape 34 is formed as a whole, and the length of the brace 10 is adjusted when the main body 31 is rotated .

In the second means, the connecting body 20 is composed of an adjusting connecting body 20A that connects the bolt portion 33 with a left-hand screw and a fixed connecting body 20B that connects the other end of the brace 10 with a right-hand screw. It is a thing.

The adjustment coupling body 20A of the third means includes a fixed portion 21 fixed to the building, and a connecting pipe 22 for connecting the extended the bolt portion 33 from the fixing unit 21.

The fixed connecting body 20B of the fourth means includes a fixing portion 21 fixed to the building and a fixed pipe 23 extending from the fixing portion 21 and connected to the brace 10.

According to the present invention, it is composed of a pair of connecting bodies 20 mounted on both sides of the brace 10 and a length adjusting body 30 interposed between one connecting body 20 and the end of the brace 10. The body 30 is provided with female screw portions 32 and bolt portions 33 at both ends of the columnar main body 31, and one end of the brace 10 is screwed to the female screw portion 32, and the bolt portion 33 is connected to one of the connecting bodies 20. By configuring it to be screwed with a left-handed screw, we succeeded in providing a turnbuckle brace that makes it easy to adjust the length without using a conventional turnbuckle body.

Moreover, since the nut shape 34 is formed on a part or the whole of the outer circumference of the main body 31, the rotation operation of the length adjusting body 30 becomes extremely easy by a tool such as a spanner.

Further, the connecting body 20 is composed of an adjusting connecting body 20A for connecting the bolt portion 33 of the female threaded portion 32 with a left-hand thread and a fixed connecting body 20B for connecting the bolt portion 33 of the female threaded portion 32 with a right-hand thread to the other end of the brace 10. Since the rotation operation of the length adjusting body 30 is the same as that of the pipe type turnbuckle body, it can be used in the same manner as the conventional turnbuckle using the turnbuckle body.

Further, the length adjusting body 30 is provided with female screw portions 32 and bolt portions 33 at both ends of the cylindrical main body 31, and one end of the brace 10 is screwed to the female screw portion 32 and the bolt portion 33 is attached. Since it is configured to be screwed to one of the connecting bodies 20, it is superior in design as compared with the configuration in which the welded portion of the long bolt is exposed as in the conventional wing plate bolt. As a result, it can be used in a building design that intentionally exposes the turnbuckle.

It is a perspective view which shows one Example of this invention. It is a front view which shows one Example of this invention. It is a top view which shows one Example of this invention. It is a front view which shows the usage state of this invention.

The present invention will be described with reference to the illustrated examples. The turnbuckle brace of the present invention is a member used for bracing of a building or the like, and mainly includes a brace 10, a connecting body 20, and a length adjusting body 30.
