Description

[Detailed Description of the Invention] This invention relates to a construction place provided to resist tension and compression forces applied to a construction.

A construction place is usually installed between pillars, beams, walls, etc. of a structure, but the place itself needs to be stretchable in order to apply appropriate tension to the structure after it is erected.

Conventionally, a place using a turnbuckle in the middle part has been known to achieve this effect.

However, when this type of place is used at a construction site, a connecting rod that is locked and connected to a turnbuckle and forms a hook or ring at one end, and a connecting rod that is connected to a column, beam, wall, etc. A fixed plate was required to be fixed to.

These connecting rods and fixing plates are made by cutting long rods or plates at the work site and forming a hook or ring at one end of the rod.
The work of drilling bolt holes in the plates and connecting these members is essential, which has the drawback of requiring a great deal of labor and time.

In addition, there is a drawback that the turnbuckle may get in the way and cannot be used, such as when the place is installed close to a wall.

Furthermore, if the device used for the turnbuckle is not in the center of the place, it may not rotate properly, and if the turnbuckle is rotated forcibly, the threaded portion of the turnbuckle will break and become unusable.

This idea consists of a screw thread in which male threads are threaded in opposite directions at both the left and right ends, the middle part is formed with a diameter smaller than the thread diameter at both ends, and a wrench locking corner is formed at an appropriate location. A construction place that eliminates the above-mentioned drawbacks is constructed from a joint part and left and right fixing bodies each having a female thread formed at one end and a fixing hole drilled at the other end, each having a female thread that engages with the male thread of the threaded part. The purpose is to obtain.

Next, this invention will be explained based on the drawings of the embodiment. Reference numeral 1 denotes a threaded part, which is shaped like a round bar, has male screws 3 screwed in opposite directions to both left and right ends 2, and has an intermediate part 4. is formed to have a smaller diameter than the thread diameter of the male threads 3 at both ends.

Here, the thread diameter a of the male screw 3 is the substantial diameter of the nearest trough and the trough.

Reference numeral 5 denotes a wrench locking corner portion formed with an appropriate width at the center or both ends of the intermediate portion, and the cross section is formed into a rectangular shape capable of fitting with a wrench.

The threaded part 1 can also be formed by separately forming the end part 2 and the intermediate part 4 and welding them on site.

Reference numeral 6 denotes a fixing plate, which is made of a long plate-like body, and female threads are provided at the center of the thickness of the plate at one end to be threaded into the male threads 3 of the threaded portion 1, respectively.

8 is a cavity continuous to the female thread 7.

9 is a circular fixing hole bored at the opposite end of the female thread 7.

Reference numeral 10 denotes a display section that displays the thread direction of the female screw of the fixing plate 6.

The female thread 7 may be provided in an enlarged manner on the side surface of the plate, and in this case, the cavity 8 is not required.

However, when using this lever device, first the fixing plates 6 are screwed onto both ends of the screwing rod 1, respectively, and the place is assembled.

At this time, the length of the place is configured to have a sufficient length so that it can be shortened after installation.

Next, install it at an appropriate position, fix the fixing hole 9 of the fixing plate 6 with a bolt, fit a spanner into the spanner locking corner 5, and rotate the screw rod 1 to obtain an appropriate tension. Shorten the place.

Since this invention has the above-mentioned configuration and operation, the work on site can be easily performed.

In addition, since the middle part of the place after erection is straight rod-shaped, it can be used even in places where turnbuckles would get in the way, and has the effect of widening the range of use, which is convenient for structures where many places are installed.

Furthermore, since the diameter of the middle part is smaller than the thread diameter of the male thread, if force is applied to the entire place, the middle part will expand, and stress will not be concentrated on the threaded part, which has the effect of avoiding damage to the threaded part. .

Furthermore, if the wrench locking corners are formed at both ends, it is effective when the place is used in a place where it is difficult to reach the center.
