DETAILED DESCRIPTION

[0034] The following is combined with Figure 1-4 This application is described in further detail.

[0035] The present application embodiment discloses a riser anti-seismic support. Figure 1 and Figure 2 The riser seismic support includes a cross bar 1 for fixed connection with the structure, a pipe clamp 2 fixedly connected to the cross bar 1 to fix the riser 01, and seismic connecting rods 3 arranged at both ends of the cross bar 1. There are three seismic supports at each end of the cross bar 1. The three seismic connecting rods 3 are claw-shaped at the end of the cross bar 1, and each seismic connecting rod 3 forms an angle with the structural plane. The angle between each seismic connecting rod 3 and the cross bar 1 is consistent, and the angle between each seismic connecting rod 3 and the structural plane is also consistent, so that the horizontal and vertical components of force generated by the seismic connecting rod 3 can be used to constrain the cross bar 1 in the horizontal and vertical directions, thereby improving the seismic performance of the support. The end of the seismic connecting rod 3 away from the cross bar 1 is fixed with a first connecting member 5 for fixing to the structural plane. The first connecting member 5 is a pressing sheet that is bent integrally to form an obtuse angle, so that the first connecting member 5 forms a mounting portion connected to the seismic connecting rod 3 and a fixing portion fixed to the structural plane by a first bolt 4. The first bolt 4 is an expansion bolt. The three anti-seismic connecting rods 3 are all fixed to the cross bar 1 through the second connecting member 6. The second connecting member 6 has the same structure as the first connecting member 5 and is also a press sheet formed by bending in one piece. That is, the three second connecting members 6 are also fixed to the same position of the cross bar 1 by a fixing bolt 16. The three first connecting members 5 are also fixed to the ends of the anti-seismic connecting rods 3 by fixing bolts 16.

[0036] Reference Figure 2 and Figure 3Several pipe clamps 2 are fixed along the length direction of the cross bar 1 to limit and fix the vertical pipe 01 installed on the seismic support of the present application, thereby reducing the probability of small-scale vibration of the vertical pipe 01. The pipe clamp 2 includes an arc-shaped embracing section 21 for embracing the vertical pipe 01 and a fixing section 22 bent outward at both ends of the embracing section 21 for connecting with the cross bar 1. The fixing section 22 is fixed to the cross bar 1 by a second bolt 14. A first rubber pad 7 is fixed on the embracing section 22, so that soft contact is achieved between the pipe clamp 2 and the vertical pipe 01, thereby improving the vibration reduction performance of the support, not easily causing collision of the vertical pipe 01, and not easily generating low-frequency noise.

[0037] In order to further improve the limiting effect on the vertical pipe 01, a baffle 10 connected to the cross bar 1 through the connecting rod 9 is also included. The baffle 10 is arranged on the outside of the pipe clamp 2 to clamp the pipe clamp 2, and the baffle 10 is parallel to the cross bar 1. A second rubber pad 12 for contacting the pipe clamp 2 is also fixed on one side of the baffle 10, and the second rubber pad 15 and the pipe clamp 2 also achieve soft contact, so that the vibration reduction performance of the seismic support of the present application is more excellent.

[0038] Reference Figure 3 Preferably, the first rubber pad 7 is a U-shaped rubber pad, that is, the longitudinal section of the first rubber pad 7 is U-shaped with an opening, and the width of the opening is consistent with the thickness of the engaging section 21, so that a U-shaped rubber pad is clamped at the upper edge and the lower edge of the engaging section 21, and the U-shaped rubber pad is arranged along the length direction of the engaging section 21, so that soft contact is achieved between the pipe clamp 2 and the riser 01 and between the pipe clamp 2 and the baffle 10, so as to improve the vibration reduction performance of the bracket.

[0039] The second end of the connecting rod 9 passes through the baffle 10 and is fastened by the nut 13, so as to adjust the distance between the baffle 10 and the cross bar 1 according to the size of the pipe clamp 2. A spring (not shown in the figure) is sleeved on the second end of the connecting rod 9, one end of the spring is fixed to the connecting rod 9, and the other end is in contact with the baffle 10. The contact between the connecting rod 9 and the cross bar 1 is also soft contact, further improving the vibration reduction performance of the seismic support of the present application.

[0040] Reference Figure 2 and Figure 4The cross bar 1 has a hollow cavity 102 inside. In order to facilitate the adjustment of the installation position of the vertical pipe 01, a guide slot 101 connected to the hollow cavity 102 is provided on the side of the cross bar 1 facing the pipe clamp 2, and the guide slot 101 and the hollow cavity 102 extend along the length direction of the cross bar 1. A fixing block 8 is fixed to the inner side of the fixing section 22 by a second bolt 14. The fixing block 8 is embedded in the hollow cavity 102, and the fixing block 8 abuts against the groove wall of the guide slot 101. By adjusting the tightness of the second bolt 14, the fixing block can slide in the hollow cavity, that is, the pipe clamp 2 can slide along the length direction of the cross bar 1, so as to adapt to the installation of vertical pipes 01 in different positions.

[0041] Furthermore, the connecting rod is a threaded rod, and a sliding block 91 is fixed to the first end of the connecting rod 9, and the sliding block 91 is embedded in the guide slot 101 and can slide along the guide slot 101. A fastener 15 for tightening and fixing with the cross bar 1 is also rotatably connected to the connecting rod 9. In the present application, the fastener 15 is a fastening nut with a pressure plate, and the cross bar 1 is pressed by the pressure plate to fix the connecting rod 9. By arranging the sliding block 91 that can slide along the hollow cavity 102 at the end of the connecting rod 9, the fixing position of the sliding block 91 can be changed according to the length of the baffle 10, so as to facilitate the fixing of the baffle 10.

[0042] The implementation principle of a seismic bracket for a riser in the embodiment of the present application is as follows: by respectively setting three seismic connecting rods 3 at both ends of the cross bar 1, the connection between the bracket of the present application and the structural plane is made more stable, so as to improve the seismic performance of the seismic bracket of the present application. By adding a pipe clamp 2 for limiting the riser 01 and a baffle 10 for limiting the pipe clamp 2, the probability of vibration of the riser 01 is reduced. By setting soft contacts between the pipe clamp 2 and the riser 01, between the pipe clamp 2 and the baffle 10, and between the baffle 10 and the cross bar 1, the probability of the bracket shaking due to the vibration of the riser 01 is reduced, thereby improving the seismic resistance and vibration reduction performance of the seismic bracket of the present application.

[0043] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
