Abstract

PROBLEM TO BE SOLVED: To enhance the strength of welding and facilitate welding and increase the workability by providing a connection body directly connected to a reinforcing steel rod at one end side of a bolt constituting a turnbuckle, inserted in a nut. SOLUTION: A turnbuckle body 1 is constituted of a nut 2 having bored holes 2a at both end sides, and two bolts 3 having lengths different from each other. A bottom connection part 4 with a hole 4a is provided at the front end of the short bolt 3 and a connection body 5 composed of a pair of bar bodies 5a is extended from the bolt 3 at the front end of the long bar-form bolt 3. The shape of the connecting part may be formed of three bar-form members or a spiral ring body. A deck metal tool is fixed at the lower end side of a building frame to connect to the bottom connection part 4. After the length of bolt 3 has been adjusted, the one end side of a steel rod fixed to the upper end side of the building frame is inserted between the bar-form bodies 5a and fixed therein. In this way, the turnbuckle can be linearly connected and the welding works can be facilitated.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a turnbuckle which is connected to, for example, a building frame by welding to a reinforcing steel bar which is inserted for necessity such as earthquake resistance and wind resistance.

[0002]

2. Description of the Related Art As a conventional turnbuckle which is welded to a reinforcing steel bar of a building frame and connected thereto,
A turnbuckle as shown in FIG. That is, the turnbuckle body 20 is inserted into a nut member 21 having a frame shape and screwed from both ends of the nut member 21, one of which is elongated and the other is a pair of short bolt members 22 a and 22 b. And the bolt member 22a
And a plate-shaped bottom connecting portion 23 provided on the shorter distal end side. When the turnbuckle is used by welding to a reinforcing steel bar of a building frame, first, the bottom connecting portion 23 is fixed below the frame, and then the bolt members 22a and 22b are connected to the nut member 21. And the length thereof is adjusted, and the distal end side of the elongated bolt member 22b is attached by welding to a reinforcing bar as shown in FIG.

[0003]

However, in order to directly weld the elongated bolt member 22b and the reinforcing bar, the conventional turnbuckle has to be welded in a state in which both members are gripped, and that is the case. The disadvantage was that the welding operation was complicated. Further, a major problem is that the connecting portion is not linear, so that the connecting portion is weak against a vertical force. Therefore, for example, the strength against a vertical earthquake or the like is not sufficient.

An object of the present invention is to solve these problems, and an object of the present invention is to provide a turnbuckle having an easily weldable and strong connecting portion.

[0005]

Means for Solving the Problems In order to achieve the above object of the present invention, the following arrangement is provided. That is, the turnbuckle according to the first aspect is a nut member 2 having a frame shape, a bolt member 3 inserted at both ends of the nut member 2, and a bottom connection provided on one side of the bolt member 3. A turnbuckle comprising a portion 4 and a connecting member 5 for linearly connecting to a reinforcing bar or the like is provided at the other end of the bolt member 3. Further, in the turnbuckle according to the second aspect, the connecting member 5 is connected to the bolt member 3.
It is at least a pair of rod-shaped members 5a provided to extend further.

[0006]

In the case where the turnbuckle according to the first aspect of the present invention is used by welding to a reinforcing bar of a building frame, the one bottom connecting portion 4 of the bolt member 3 is provided at the lower end of the frame. Is fixed, the length of the bolt member 3 is adjusted with the nut member 2 having a frame shape in order to make the reinforcing bar fixed to the upper end side and the other connection portion of the bolt member 3 linear. And the rebar. This makes it possible to weld the reinforcing bar and the bolt member 3 in a straight line.

The turnbuckle according to claim 2 is
Since the connecting portion is at least a pair of rods provided so as to extend from the bolt member, it is possible to easily perform welding by welding with the rebar sandwiched between the rods.

An embodiment will be described below, but the embodiment of the present invention is not limited to this. In FIG. 1, reference numeral 1 denotes an elongated frame having a space in the center, and a nut member 2 having holes 2a formed at both ends thereof;
2 having different lengths screwed in opposite directions to the holes 2a, respectively.
5 shows a turnbuckle main body including a plurality of rod-shaped bolt members 3. The operation of rotating the bolt member 3 causes the bolt member 3 to be inserted into the nut member 2 or to extend from the nut member 2, whereby the length thereof can be adjusted. Reference numeral 4 denotes a plate-like bottom connecting portion provided at the tip of the short rod-shaped bolt member 3 and having a hole 4a at the tip thereof. Reference numeral 5 denotes the other distal end of the long rod-shaped bolt member 3. And a connecting body composed of a pair of rod-shaped members 5a fixed in a state of being opposed to the bolt member 3 and extending a predetermined amount from the tip of the bolt member 3.

Next, when using the above-mentioned turnbuckle, as shown in FIG. 2, a deck fitting 7 is fixed to the lower end side of the building frame 6 and the deck fitting 7 is attached to the short rod-shaped bolt member 3.
And is connected to the hole 4a of the plate-shaped bottom connecting portion 4 provided at the front end portion. Next, holes 2a are formed at both ends of the nut member 2.
After adjusting the length of the rod-shaped bolt members 3 screwed into and inserted into each other, the other end of the reinforcing bar 8 whose one end is fixed to the upper end of the building frame 6 is connected to the long end. It is inserted and welded between a pair of rods 5a provided at the tip of the rod-shaped bolt member 3. Thereby, it is possible to connect the reinforcing bars 8 linearly. Moreover, since the rebar 8 is inserted between the pair of rods 5a and welded, the welding operation can be easily performed.

In the above embodiment, the nut member 2 has a frame shape, but the shape of the nut member 2 is not limited to this, and may be, for example, a cylindrical shape. The point is that the shape of the rod-shaped bolt member 3 does not matter as long as its length can be adjusted by screwing and inserting the bolt member 3 or the like.

In the above embodiment, the connecting portion is formed as a pair of rods. However, the shape of the connecting portion of the present invention is not limited to this. For example, as shown in FIG. It may be formed as a book, may be formed with three or more, and may be formed with a spiral ring body. The point is that the rebar or the like to be connected can be linearly connected to the rod-shaped bolt member 3 and the shape is not limited as long as the shape is easy to weld.

Further, although the bottom connecting portion 4 is formed of a plate-like body provided at the tip, the shape of the bottom connecting portion 4 is not limited to this, and a shackle may be used. In short,
The shape does not matter if it can be easily connected to the deck fitting 7.

[0013]

As described above, since the turnbuckle according to the present invention is provided with a connecting body for linearly connecting to a reinforcing bar or the like, a step is provided like a conventional turnbuckle. There is a remarkable effect that the connection can be made linearly without connection, and the strength of welding can be further increased.

Further, by forming the connecting body with a pair of rods or more, a reinforcing bar or the like can be inserted between the rods and welding can be performed, so that the welding is much easier than before and the workability is improved. The advantage is that it can be achieved.
