Description

[Detailed description of the invention] The invention relates to a place, and more specifically, a left-handed female screw hole 2a is bored in one of a pair of battledores la and lb for attaching and fixing to a structural material such as a beam. A right-handed female screw hole 2b is bored in the other one, and the base end of one of the pair of reinforcing rods 4a and 4b has a fishing hook part 3 at the tip for hooking and engaging with each other. A left-handed male threaded portion 5a is screwed into the left-handed female threaded hole 2a of the battledore 1a so that it can be freely advanced and retracted, and a right-handed male threaded portion 5b is screwed into the base end of the other one. This relates to a place that is screwed into the right-handed female threaded hole 2b of 1b so that it can be screwed forward and retracted.

In the conventional place, as shown in FIG.
A left-handed male threaded portion 5a' is provided at the tip of one of 4 b', a right-handed male threaded portion 5b' is provided at the tip of the other, and the tip of the pair of reinforcing bars 4a', 4b' is The comrades were connected by screwing them into turnbuckle 6, respectively.

Therefore, in order to install this place A' between the structural members such as the main beam 7 and the small beam 8, turn the turnbuckle 6 in accordance with the distance between the bolt holes screwed into the structural members in advance. After adjustment, both battledore boards 1' were fixed to the structural member with bolts 10, and then the turnbuckles 6 had to be turned again to tension the place A', making the construction time-consuming.

The present invention was made in view of the drawbacks of the conventional examples mentioned above, and its purpose is to provide a place that is easy to construct and does not require adjustment of the length of the place before attaching and fixing the battledore. be.

The present invention will be explained in detail below with reference to the accompanying drawings.

la and lb are a pair of battledores shaped like a ring,
One of the battledores 1a is provided with a left-handed female screw hole 2a and one or more bolt insertion holes 11, the number of which corresponds to the strength of the bolts 10, and the other battledore 1b is provided with a right-hand screw. A female threaded hole 2b is bored, and one or more bolt insertion holes 11 are provided in a number corresponding to the strength of the bolt 10.
is perforated.

Reference numerals 4a and 4b denote a pair of reinforcing bar rods of different lengths, each of which has a hook portion 3 bent in a fishing shape at its tip, and a left-handed male threaded portion 5a is screwed into the base end of one reinforcing bar 4a. carved,
A right-handed male threaded portion 5b is threaded on the base end of the other reinforcing bar 4b.

The left-handed male threaded portion 5a of one reinforcing bar 4a is screwed into the left-handed female threaded hole 2a of one of the battledores 1a so as to be able to be screwed forward and backward, and the right-handed male threaded portion 5b of the other reinforcing bar 4b is screwed into the left-handed female threaded hole 2a of one battledore 1a. It is screwed into a right-handed female threaded hole 2b of the battledore board 1b so that it can be freely advanced and retracted, and the hook portions 3 of both reinforcing rods 4a and 4b can be hooked and engaged with each other.

Therefore, during construction, bolts 10 are passed through the bolt insertion holes 11 of the battledore 1a screwed together with one reinforcing bar 4a, and the bolts are fixed to structural members such as the main beam 7, small beams 8, and columns 9, and then the other The battledore 1b screwed to the reinforcing bar 4b is also fixed to the structural member with bolts 10, both reinforcing bars 4a, 4b are turned to contract, and the hook portions 3 of both reinforcing bars 4a, 4b are hooked and engaged. While still holding the hook part 3, both reinforcing bars 4a,
4b at the same time to tension the reinforcing rods 4a and 4b.

The ones shown in FIGS. 5 to 7 are other examples of the present invention, in which a plurality of left-handed female screw holes 2a are provided in the battledore 1a or 1b.
Or, by drilling a right-handed female threaded hole 2b, one battledore 1a
Or, multiple reinforcing rods 4a or 4b can be attached to 1b, with two female threaded holes in Fig. 5, three female threaded holes in Fig. 6, and four female threaded holes in Fig. 7. A female screw hole is drilled.

For example, as shown in FIG. 8, by simply fixing one battledore 1a or 1b to a structural member with bolts 10, four reinforcing bars 4a or 4b can be stretched at once, and one battledore 1a or 1b can be stretched at a time.
The number of bolts required for attaching b is small, and the labor of construction is further reduced.

As described above, the present invention involves drilling a left-handed female threaded hole in one of a pair of battledocks for attaching and fixing to a structural material such as a beam, and drilling a right-handed female threaded hole in the other. ,
A left-handed male screw threaded on the base end of one of a pair of reinforcing bar rods having a hook-like hook portion at the tip thereof is screwed into the left-hand female screw hole of the battledore so as to be able to be screwed forward and retracted, and the other The male threaded part of the right-hand thread screwed on the base end of the object is screwed into the female threaded hole of the right-hand thread of the battledore so that it can be freely advanced and retracted, and the hook parts of the reinforcing bars are hooked and engaged with each other. In this case, one of the battledores screwed to one reinforcing bar is fixed to the structural member, the other battledore threaded to the other reinforcing bar is fixed to the structural member, and then both reinforcing bars are rotated. This allows the hook parts of both reinforcing bar bars to intersect and engage with each other while being compressed, and then both reinforcing bar bars can be turned together to tension the reinforcing bars. There is no need to adjust the length in advance, and the construction has the advantage of being easy and hassle-free.
