Description

Technical Field

[0001] The utility model relates to the technical field of earthquake-resistant brackets, and in particular to an earthquake-resistant bracket for an air duct with bidirectional support. Background Art

[0002] In view of the great destructiveness of earthquakes, seismic performance is an important indicator that must be considered before building construction, and the laying of pipes in buildings is an important factor affecting seismic performance. If the fixing of pipes does not meet the requirements, the falling pipes and their auxiliary structures will cause huge casualties during earthquakes. After seismic reinforcement, the electromechanical engineering facilities such as water supply and drainage, fire protection, heating, ventilation, air conditioning, gas, heat, electricity, and communications in buildings can reduce earthquake damage, reduce and prevent secondary disasters as much as possible when encountering earthquakes with seismic fortification intensity in the region, thereby reducing casualties and property losses. Seismic brackets are used to limit the displacement of auxiliary electromechanical engineering facilities, control the vibration of facilities, and transfer loads to various components or devices on the load-bearing structure. However, the air duct is made of thin galvanized iron plates as a whole, and is prone to deformation when the fastening force used during fixing is relatively large. The invention patent with application number CN201910643797.X discloses a lateral longitudinal seismic support for an air duct, comprising at least two transverse shock-absorbing frames, wherein both ends of one of the transverse shock-absorbing frames are connected to support frames; each two transverse shock-absorbing frames are connected by a connecting frame, and two connecting frames are provided, and the two connecting frames are respectively located at both ends of the transverse shock-absorbing frames, and each transverse shock-absorbing frame is provided with a lateral longitudinal shock-absorbing member, and each lateral longitudinal shock-absorbing member is located at the middle position of each two transverse shock-absorbing frames, and the lateral longitudinal shock-absorbing member is arranged in a direction perpendicular to the connecting frame; the lateral longitudinal shock-absorbing member comprises a sliding baffle rod, and a shock-absorbing rod is hingedly connected to the sliding baffle rod at the center position of one side of the transverse shock-absorbing frame, and the other end of the shock-absorbing rod extends into the interior of the transverse shock-absorbing frame, thereby improving the shock-absorbing effect of the shock-absorbing bracket in all directions, ensuring the fixing effect on the air duct, and enhancing the stability of the air duct after installation, but the device has a complex structure and high manufacturing cost. Utility Model Content

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] An air duct seismic support with bidirectional support, comprising a U-shaped support fixedly installed on a building structure. Diagonal support rods are obliquely arranged on both sides perpendicular to each other at the left and right ends of the U-shaped support. An upper elastic support is detachably installed at the bottom of the U-shaped support. A U-shaped mounting frame is installed at the bottom of the U-shaped support. A lower elastic support is detachably installed on the U-shaped mounting frame. An air duct is installed between the upper elastic support and the lower elastic support.

[0006] Preferably, a transverse support beam is detachably installed on the U-shaped support, and a pipe hoop is arranged on the transverse support beam.

[0007] Preferably, the U-shaped support includes two vertically arranged support rods arranged in parallel at intervals and a transverse support rod adjustably and fixedly installed between the two vertically arranged support rods. The top of the vertically arranged support rod is fixedly installed on the building structure through a T-shaped connector.

[0008] Preferably, the four diagonal support rods support the U-shaped support from two mutually perpendicular directions.

[0009] Preferably, the upper elastic support and the lower elastic support have the same structure, including a support plate, a pressing plate adjustably installed on the support plate through a screw, and a spring sleeved on the bolt. The two ends of the spring respectively abut against the support plate and the pressing plate. The support plate is detachably installed on the U-shaped mounting frame or the U-shaped support.

[0010] Preferably, three bolts are arranged on one of the pressing plates.

[0011] Preferably, rubber cushion blocks are arranged on the pressing plate.

[0012] In the present utility model, the four diagonal support rods arranged support the U-shaped support stably from two mutually perpendicular directions, improving the stability of hoisting and ensuring the seismic resistance of the support during use. When an earthquake or vibration caused by other factors occurs, a certain amount of vibration can be absorbed through the upper elastic support and the lower elastic support arranged, and it has good vibration absorption ability. The upper elastic support and the lower elastic support arranged increase the contact area with the air duct and have good connection stability. The rubber cushion blocks arranged can increase the friction of contact and ensure the connection stability. BRIEF DESCRIPTION OF THE DRAWINGS
