A fastening hole 15 connected to the placement space 12 is passed through the other side surface of the fixing part 10 and a screw is formed around the fastening hole 15.

Next, the first fastening portion will be described with further reference to Figs. 6 and 7. Fig.

Fig. 6 is an enlarged view of the first fastening portion of Fig. 5, and Fig. 7 is a state of operation of the first fastening portion and the second fastening portion of Fig.

2 to 7, the first fastening part 20 is fastened to the fastening hole 15 and fixes the fastening part 10 to the section steel 2. [ The first fastening portion 20 includes a fastening member 21 and a rod 22.

The fastening member 21 is composed of a bolt and is screwed to the fastening hole 15. [ 2 to 6, the head portion is shown in the bolt, but the head portion may be omitted. In this case, a hexagonal groove may be formed in the bolt.

One side of the fastening member 21 is located in the arrangement space 12 and can face the section steel 2 with a gap therebetween. However, the fastening member 21 can move in the direction of the section 2 as it is fastened to the fastening hole 15 and can be in contact with the section 2. Inside the fastening member 21, a rod hole 211 penetrating along the longitudinal direction is formed. The diameter of the rod hole 211 is formed to be the same along the longitudinal direction.

The rod 22 has a predetermined length and is disposed in the rod hole 211 and includes a body portion 221, a contact portion 222, and a display portion 223.

The body portion 221 and the display portion 223 are integrally formed and the body portion 221 and the display portion 223 are located in the rod hole 211 and the contact portion 222 is located on one side of the fastening member 21 And is exposed to the outside.

In addition, the end of the fastening member 21 can pass through the pressure panel 23 and be in contact with the section steel 2.

Hereinafter, description will be given with reference to Figs. 2 to 7. Fig.

Referring again to FIGS. 2 to 7, the adjustment portion 30 is connected to one side of the fixing portion 10. A bracing bar insertion hole 31 into which a part of the bracing bar 302 is inserted is formed at one side of the regulating part 30. [

A part of the one side of the regulating part 30 can be inserted into the bracing bar 302 with reference to the bracing bar insertion hole 31. However, as shown in FIGS. 8 and 9, the bracing bar insertion hole 31 may be formed in a groove shape, so that a portion of the bracing bar 302 may be inserted into the bracing bar insertion hole 31. The bracing bar 302 is fixed to the regulating portion 30 by the second fastening portion 60.

One side of the regulating portion 30 is reinforced by the reinforcing rib 32 when the regulating portion 30 is seen from a plane. Thus, the thickness of one side of the regulating portion 30 is thicker than the other side. One side of the regulating portion 30 is formed with a fastening hole 33 communicating with the bracing bar insertion hole 31 and having a screw.

The other side of the regulating portion 30 is located in the arrangement space 12 and overlaps with one side of the fixing portion 10. A gap is formed between the outer periphery of the regulating portion 30 and the periphery of the arrangement space 12. [ An adjustment through hole 34 communicating with the fixed through hole 11 is formed in the portion of the adjustment portion 30 overlapping with the fixed through hole 11.

The connection shaft 40 has a predetermined length and the outer peripheral diameter is smaller than the diameter of the fixed through-hole 11 and the adjustment through-hole 34. The connecting shaft 40 passes through the fixed through hole 11 and the adjusting through hole 34 and rotatably connects the adjusting portion 30 and the fixing portion 10. The adjusting unit 30 and the fixing unit 10 may be rotated with respect to the connecting shaft 40 in a state of being connected through the connecting shaft 40. [

The connection shaft 40 is composed of a bolt and a nut and the gap is narrowed as the bolt passing through the fixed through-hole 11 and the adjustment through-hole 34 is combined with the nut, ) Are brought into contact with and fixed to each other. The fixed fixing part 10 and the adjusting part 30 do not rotate with respect to the connecting shaft 40.

The adjusting portion 30 and the fixing portion 10 can rotate based on the connecting shaft 40 in a state where the bolt and the nut of the connecting shaft 40 are loosely fastened. When the fixing part 10 is fixed to the section steel 2, only the adjusting part 30 can rotate around the connecting shaft 40. [

The angle display unit 223 includes an angle scale 51 and a reference scale 52 and allows the rotation angle of the adjustment unit 30 to be ascertained based on the connection axis 40.

The angle scale 51 is arranged along the circumferential direction around the fixed through-hole 11. The array angle R of the angle scale 51 is 15 degrees. However, the arrangement angle of the angle scale 51 may be variously changed depending on the installation place and the design. The angle scale 51 is formed only on the left side of the fixed portion 10 with respect to the longitudinal virtual center line 11c of the fixed through-hole 11. The angle scale 51 is formed in a negative angle shape.

The reference graduation 52 is formed on the other side of the regulating portion 30 which is adjacent to the regulating through hole 34 and is not overlapped with the fixing portion 10. The reference scale 52 coincides with the transverse virtual center line 34c of the adjusting through hole 34. [ The reference scale 52 is formed in a negative angle shape. The reference scale 52 may coincide with any scale of the angle scale 51 when the adjustment unit 30 rotates. Therefore, the operator can confirm the angle formed by the adjusting portion 30 with the fixing portion 10 without using the angle measuring tool in the field. Thus, workability can be improved.

On the other hand, a luminous pigment or glass bead or the like can be applied to the angle scale 51 and the reference scale 52. The angle of the regulating portion 30 can be easily confirmed even in a dark working environment through the use of a phosphorescent pigment or a glass bead. Since the bracing bar 302 and the adjusting portion 30 are coupled by the second fastening portion 60, the bracing bar 302 can be formed at a predetermined angle with the fixing portion 10, have.

The second fastening portion 60 includes a fastening member 61 and a rod 62. The fastening member (61) presses the bracing bar (302) as it is fastened to the adjuster (30). The rod 62 can be moved to the inside of the fastening member 61 at one side and exposed to the outside of the fastening member 61 at the other side according to the fastening of the fastening member 61. The degree of tightening of the fastening member 61 can be confirmed in accordance with the exposure of the rod 62. [ Since the fastening member 61 and the rod 62 are the same as the fastening member 21 and the rod 22 of the first fastening portion 20 described above, a duplicate description will be omitted.

Next, the operation of the anti-shake brace described above will be described with reference to Figs. 1 to 7 again.

First, in a state in which the connection shaft 40 is loosely engaged, the fixing portion 10 is positioned on the section steel 2 adjacent to the pipe 1 to position the section steel 2 in the section steel insertion hole 13. [ The pressure panel 23 faces the section steel 2 with a gap. When the fastening member 21 of the first fastening portion 20 is fastened in the tightening direction, the pressurizing panel 23 can press the section steel 2. [

The end portion of the contact portion 222 contacts the section 2 and the fastening member 21 is continuously tightened so that the fastening member 21 moves in the direction of the section 2 and the contact portion 222 gradually moves into the fastening member 21 And the display portion 223 is exposed to the outside of the fastening member 21 in proportion thereto. The display groove 223a is exposed to the outside of the fastening member 21 by the exposure of the display portion 223. [ The fastening state of the fastening member 21 can be confirmed by exposure of the display groove 223a.

The fastening member 21 may move in the direction of the section 2 and the display unit 223 may move to the rod hole 211 by applying a predetermined torque (20 ft / 1 bs) when the fastening member 21 is fastened. The fixing portion 10 can be firmly fixed to the section 2 while the end of the fastening member 21 is in contact with the section 2. [

The bracing bar 302 to which the clamp 303 for wrapping and fixing the pipe 1 is coupled is fixed to the regulating portion 30 by using the second fastening portion 60. The operation of the second fastening part 60 is the same as that of the first fastening part 20, so duplicated description will be omitted.

The adjusting unit 30 is rotated with respect to the connecting shaft 40 in accordance with the position of the pipe 1. At this time, the angle of the adjusting unit 30 is adjusted while checking the angle scale 51 and the reference scale 52 of the angle display unit 50. The angle display unit 50 allows the operator to adjust the angle of the adjustment unit 30 with reference to the fixed unit 10 without using the angle measurement mechanism. When the angle of the adjusting part 30 is adjusted, the connecting shaft 40 is tightened to fix the adjusting part 30 to the fixing part 10 so as not to move. The clamp 303 is coupled to the pipe 1 so that the pipe 1 is supported on the pipe 2. [

Therefore, the pipe 1 is formed of a single member in which the pipe 1 and the section steel 2 are integrally formed by the anti-shake brace 3, and the pipe is made to behave integrally with the section steel. The vibration applied to the pipe can be reduced and the impact energy can be dissipated.

When the predetermined torque is applied to the fastening member 21, the contact portion 222 is moved into the fastening member 21 and the display portion 223 is exposed to the outside of the fastening member 21. Thus, the construction supervisor and the contractor can visually confirm whether the fastening state of the fastening member is accurately made (tightened) by the specified torque.
