According to the position of the length adjustable front and rear adjustment member 40 is provided, the rear of the front and rear adjustment member 40, the vertical adjustment screw rod 60 and the horizontal adjustment screw rod 61, the upward direction, the lateral direction, The cross-type entrance 50 is provided to achieve downward movement, and the vertical adjustment screw rod 60 and the horizontal adjustment screw rod are movable in the upward, lateral direction, and downward direction at the cross-shaped entrance 50. (61) is provided, the rotation adjusting means 80 is provided at the ends of the vertical adjustment screw rod (60) and the horizontal adjustment screw rod (61), the reinforcing bar connected to the rotation control means (80) and reinforcement (100) ) Is provided with a holding part 70 for holding.

The front and rear entrances and exits 30 of the rear of the fastening box 20 may be manufactured integrally or combined with the fastening box 20, and the crosswise entrance 50 of the rear of the front and rear control member 40 may also be the front and rear control member 40. ) Can be manufactured in one piece or in combination.

It is possible to adjust the length of the front and rear adjustment member 40 in the front and rear entrance 30, referring to Figure 2 together, the front and rear entrance 30, the engaging pin 31 is inserted into the locking pin ( 31) the stepped portion 32 is formed at the lower portion, and the spring 33 is formed on the bottom surface of the stepped portion 32 and the front and rear exit 30 while being inserted into the locking pin 31, and the front and rear adjustment member is provided. The upper surface of the 40 has a recessed portion 41, the center of the engaging hole 42 and the passage portion 43 having a diameter smaller than the diameter of the engaging hole 42 is sequentially formed.

The cutting part 31a of the upper part of the locking pin 31 is for facilitating the drawing of the locking pin 31.

Therefore, in order to adjust the length of the front and rear adjustment member 40 entering and exiting from the front and rear entrance 30, when pulling out the front and rear adjustment member 40 to the rear or pulled forward. The spring 33 is compressed upward by the stepped portion 32 of the locking pin 31 so that the front and rear adjustment member 40 moves forward and backward because there is no catch of the passage 43 of the front and rear adjustment member 40. At this time, in order to stop the front and rear adjustment member 40 at an appropriate position, the locking pin 31 stepped portion 32 is lowered by the elastic restoring force of the compressed spring 33 by releasing the locking pin 31 in a pulled state. It moves in the direction and the locking pin 31 with the spring 33 is inserted into the locking hole 42 is made in the passage 43, the front and rear adjustment member 40 is fixed while being stopped.

That is, the front and rear adjustment member 40 at the front and rear entrance and exit 30 receives movement and movement control according to the drawing and return of the locking pin 31 to adjust the position length of the holding part 70 held on the reinforcing bar 100. do.

On the other hand, the cross-shaped entrance (50) provided on the rear of the front and rear adjustment member (40) enters the vertical adjustment screw rod 60 and the horizontal adjustment screw rod 61 in the upper and lower directions, respectively, and the reinforcement of the holding portion 70 (100) Induces holding.

That is, the vertical adjustment screw rod 60 and the horizontal adjustment screw rod 61 is rotated to adjust the length of the up, down, both sides and induces the holding of the reinforcement 100 of the holding portion 70.

The vertical adjustment screw rod 60 and the end of the horizontal adjustment screw rod 61 will be described with reference to Figure 3, the rotation control means 80 is connected to the other side of the rotation control means 80 holding portion ( 70 is a single rod 71 connection is made.

Looking at the rotation control means 80 in more detail, the disk 81 is provided, the disk 81 forms a symmetrical long groove 82 to achieve a rotation at a constant interval, the disk 81 of A protruding hook portion 83 is formed at regular intervals along the circumference.

The single rod 71 of the holding portion 70 hinged to the disc 81 of the rotation control means 80 is formed integrally with the single rod 71 and the engaging bar 72 protruding to both sides at the end. The holding unit 70 is rotated by the structure in which the hanging table 72 is rotated along the long groove 82 of the disc 81.

The holding unit 70 is rotated so as to accurately hold the reinforcement reinforcement 100 and at the same time under the control of the rotation to achieve a fixed, which is referred to in conjunction with Figure 4, the hinge 72 is connected to the hinge The holding unit 70 is fixed by the pivot 73 being caught by the hook portion 83 of the disc 81.

As described above, the junction box fixing device for indoor wiring of the present invention can achieve the correct position installation of the junction box not only in the right and evenly reinforced rebars but also in the case of reinforcing bars that are not properly reinforced, and also the concrete load during concrete placing. In addition to preventing the junction box flow by the has the effect that can be prevented together with the position change caused by the filling with concrete.

The operation state of the junction box fixing device for indoor wiring of the present invention will be described below.

In the state that the locking pin 31 is drawn out, the front and rear control member 40 is moved forward and backward and adjusted so that the holding part 70 is placed in a straight line vertically at the holding position of the rebar 100, and then the locking pin 31 The locking pin 31 is returned by the spring 33 restoring force, and the locking pin 31 and the spring 33 are inserted into the locking hole 42 of the front and rear adjustment member 40, thereby making a locking. Controlled by the movement of the front and rear adjustment member 40 is fixed.

At this time, the free movement of the front and rear adjustment member 40 when the locking pin 31 is pulled out, the locking pin 31 is drawn upward by the compression of the spring 33 so that only the lower end of the locking pin 31 is locked. This is because the passage 43 continued to 42 passes without jamming.

Soon, the vertical adjustment screw rod (60) and the horizontal adjustment screw rod (61) in the cross-shaped entry and exit (50), respectively, to adjust the length in the vertical direction up and down, and the reason of the length adjustment at this time is held in the reinforcement (100) This is to induce the part 70 to be close to and held.

Next, the holding unit 70 is rotated and adjusted so as to be accurately held in the reinforcing bar 100, and then the folding unit 73 is folded from the locking unit 72 provided at the end of the holding unit 70. By hooking the hook portion 83 protruding from the disc 81 of the) is fixed by the rotation control of the holding portion 70 is made to hold the reinforcing reinforcement 100 correctly.

As described above above, the junction box fixing device for indoor housing wiring according to the present invention achieves an accurate holding even in reinforcing bars reinforced by construction at the time of construction, and achieves the exact position installation of the junction box, and also concrete when placing concrete It is also possible to prevent the junction box swing due to the load, and to prevent the defect that the installation position is changed by being embedded with the concrete.

The present invention is not limited to the above-described specific preferred embodiments, and various modifications can be made by those skilled in the art without departing from the gist of the present invention as claimed in the claims. Of course, such changes will fall within the scope of the claims.
