Description

Technical Field

[0001] The utility model relates to the technical field of earthquake-resistant brackets, in particular to an earthquake-resistant combined bracket for a square air duct. Background Art

[0002] Earthquakes are natural phenomena that produce seismic waves. When a destructive earthquake occurs, buildings will shake violently, which will also affect the pipeline system. In order to prevent the pipeline system from being damaged during an earthquake, seismic supports are often used to support the pipeline system. Seismic supports limit the displacement of attached electromechanical engineering facilities, control the vibration of the facilities, and transfer the load to various components or devices on the bearing structure. Seismic supports should provide reliable protection for building electromechanical engineering facilities during an earthquake and withstand earthquakes from any horizontal direction.

[0003] Among them, the square air duct seismic composite bracket serves as a support frame for fixing the rectangular air duct in the earthquake-resistant building, and plays a certain fixing role.

[0004] In the prior art, square duct seismic composite brackets are mostly used to fix ducts by threading bolts with through holes on channel steels. However, the positions of through holes on existing channel steels are mostly fixed. Therefore, when fixing ducts of different specifications, it is necessary to find corresponding positioning holes on the channel steels to fix the ducts, which is inconvenient. Moreover, it is easy to have the situation that the screw hole positions do not match and the thickness of the cushion layer needs to be increased. Utility Model Content

Two fixing blocks 4 are arranged at intervals on the opposite sides of the two cross bars 3; the cross bars 3 are provided with long holes 5 along their length, and the fixing blocks 4 are horizontally slidably connected to the long holes 5. By setting two cross bars 3, the square air duct can be clamped and fixed up and down, and the distance can be adjusted up and down by means of the screw rods 2 to match the height of the air duct. By setting two fixing blocks 4 on the cross bars 3, the two sides of the square air duct can be clamped and fixed by means of the fixing blocks 4. By setting the long holes 5, the distance between the two fixing blocks 4 can be adjusted according to the width of the square air duct.

[0024] like Figure 2 As shown, the fixing block 4 is slidably connected to the long hole 5 through a screw rod 6, the screw rod 6 is slidably arranged in the long hole 5, one end of the screw rod 6 is connected to the fixing block 4 on one side of the cross bar 3, and the other end is sleeved with a locking nut 7 on the other side of the cross bar 3. Through the cooperation of the screw rod 6 and the locking nut 7, when it is necessary to adjust the position of the fixing block 4, by loosening the locking nut 7, the fixing block 4 can be moved horizontally along the long hole 5. After the adjustment is completed, the position of the fixing block 4 can be fixed by tightening the locking nut 7, so that the two sides of the square air duct are clamped by the cooperation of the two fixing blocks 4.

[0025] A first tooth opening 8 is provided at the edge of the long hole 5 along the length direction of the long hole 5 on one side where the cross bar 3 and the fixing block 4 are connected, and a second tooth opening 9 meshing with the first tooth opening 8 is provided on one side where the fixing block 4 is attached to the cross bar 3. By providing the first tooth opening 8 and the second tooth opening 9, the fixing block 4 can be better fixed so that the fixing block 4 will not be easily displaced during use. Even if the locking nut 7 is loosened, the first tooth opening 8 and the second tooth opening 9 can be used to prevent the fixing block 4 from being displaced.

[0026] The side of the fixing block 4 away from the cross bar 3 is connected with a stop bar 10. By setting the stop bar 10, the middle position of the square air duct can be supported, and the square air duct is more evenly stressed when vibrating by increasing the support area, and the air duct will not be deformed due to local support.

[0027] A threaded hole 11 is provided on the side of the fixing block 4 away from the cross bar 3, and a thread matching the threaded hole 11 is provided on the outer wall of the lower end of the blocking rod 10, and the lower end thread of the blocking rod 10 is matched and arranged in the threaded hole 11, and a retaining ring 12 is sleeved on the outer wall of the upper end of the blocking rod 10, and the edge of the retaining ring 12 is flush with the edge of the fixing block 4.
