Description

Technical Field

[0001] This utility model relates to the field of HVAC brackets, specifically an HVAC bracket. Background Technology

[0002] In HVAC systems, building water supply and drainage, and industrial pipeline engineering, pipelines need to be reliably supported and fixed. These support devices are usually called pipe supports or hangers. Their core function is not only to bear the static load of the pipeline, medium and insulation layer, but more importantly, to effectively deal with the dynamic load and vibration of the pipeline caused by thermal expansion and contraction, equipment vibration or fluid pulsation.

[0003] Traditional fixed support structures are simple in structure and provide stable support, but lack vibration damping capabilities. Vibrations generated during pipeline operation are directly transmitted to the building structure through rigid supports, producing noise. Over the long term, this not only affects the normal operating life of connected equipment but may also cause fatigue damage to the support itself or the connecting structure, posing safety hazards. Existing technologies have developed various elastic supports or vibration damping brackets, which typically absorb and buffer energy by introducing rubber pads into the support structure. However, many existing designs are complex and inconvenient to install and debug; or the vibration damping elements are exposed and susceptible to environmental corrosion, affecting their performance. Therefore, designing a new type of HVAC support is essential to solve this problem. Utility Model Content

The support assembly 60 is the main load-bearing structure, and its top directly supports the pipe through the load-bearing assembly 70.

[0042] The base 10 is a rectangular base.

[0043] The base assembly 30 includes: a cylindrical base 31 mounted on the upper surface of the base 10 and two pairs of reinforcing plates 32 mounted on the side surface of the cylindrical base 31. The cylindrical base 31 is vertically mounted on the upper surface of the base 10. One end of the two pairs of reinforcing plates 32 is fixedly connected to the side surface of the cylindrical base 31, and the other end of the two pairs of reinforcing plates 32 is fixedly connected to the upper surface of the base 10.

[0044] The base 10 is a rectangular steel plate made of Q235B carbon steel. Four threaded holes are opened on the upper surface of the base 1, arranged in a rectangular array. The mounting bolts 20 are stainless steel expansion bolts, which fix the base 1 to the building structure through the threaded holes. The base assembly 30 includes a cylindrical base 31 and two pairs of reinforcing plates 32. The cylindrical base 31 is a steel cylinder, which is vertically welded to the upper surface of the base 1. The reinforcing plates 32 are thick steel plates, which are symmetrically welded between the side of the cylindrical base 31 and the upper surface of the base 10 to form a stable support structure.

[0048] The support part includes a cylindrical support shell 51, which has a hollow structure inside and a circular opening on its upper surface.

[0049] The telescopic part includes: a telescopic spring 52 installed inside the cylindrical bearing housing 51, a limiting block 53 installed on the telescopic spring 52, a support connecting rod 54 installed on the limiting block 53, an annular connecting plate 55 installed on the upper side surface of the cylindrical bearing housing 51, a limiting housing 56 installed on the annular connecting plate 55, and two pairs of fixing bolts 57 installed on the limiting housing 56. The telescopic spring 52 is connected to the bottom of the cylindrical bearing housing 51. The limiting block 53 is located above the telescopic spring 52 and connected to the telescopic spring 52. The diameter of the limiting block 53 matches the inner diameter of the cylindrical bearing housing 51. The annular connecting plate 55 is connected to the limiting housing 56 by two pairs of fixing bolts 57. The support connecting rod 54 extends out of the limiting housing 56.

[0050] The shock absorption assembly 50 includes: a cylindrical bearing housing 51 and a telescopic part. The cylindrical bearing housing 51 is a steel cylinder, welded and fixed to the upper surface of the second connecting plate 42. A telescopic spring 52 is installed inside it. The limiting block 53 is a nylon disc, welded and fixed to the top of the telescopic spring 52. The supporting connecting rod is a stainless steel round rod, with its lower end threaded to the center of the limiting block 53 and its upper end passing through the limiting housing 56 and connected to the supporting housing 61. The annular connecting plate 55 is welded to the upper outer wall of the cylindrical bearing housing 51 and connected to the limiting housing 56 by fixing bolts 57 to form a closed structure to prevent the spring from falling off.

[0051] The support assembly 60 includes a support housing 61, which is mounted on the upper surface of the support connecting rod 54.

[0052] The support assembly 70 includes: an arc-shaped support plate 71 mounted on the upper surface of the support housing 61 and a pair of arc-shaped limiting housings 72 mounted on the arc-shaped support plate 71, with the pair of arc-shaped limiting housings 72 mounted at both ends of the arc-shaped support plate 71.

[0053] The support housing 61 is a steel housing, and its bottom is welded and fixed to the support connecting rod 54. The bearing component 70 includes: an arc-shaped bearing plate 71 and a pair of arc-shaped limiting housings 72. The arc-shaped bearing plate 71 is welded to the upper surface of the support housing 61.

[0054] First, fix the base 10 to the building structure using mounting bolts 20. The mounting bolts 20 must be driven in vertically. Check the levelness of the base 10; if necessary, add thin steel shims for adjustment. Vertically weld the cylindrical base 31 to the base 10. Symmetrically weld the reinforcing plates 32 between the sides of the base and the base. The welds must be fully welded and ground smooth. Weld the first connecting plate 41 to the upper surface of the cylindrical base 31. Fix the second connecting plate 42 to the first connecting plate 41 using connecting bolts 43. The connecting bolts 43 must be tightened crosswise. Install the telescopic spring 52 into the cylindrical bearing housing 51. Weld the limiting block 53 to the top of the telescopic spring 52. Thread the lower end of the support connecting rod 54 to the limiting block, and pass the upper end through the limiting housing 56. The curved connecting plate 55 and the limiting housing 56 are locked together by fixing bolts 57, ensuring that the spring compression amount is reserved with 10% to 15% of the stroke to buffer vibration. The bottom of the support housing 61 is welded to the upper end of the support connecting rod 54. The weld must be continuous around the circumference. After welding, the weld slag is removed and anti-rust paint is applied. The arc-shaped bearing plate 71 is welded to the top of the support housing 61, and the arc-shaped limiting plates are symmetrically welded to both ends to ensure that the arc radius matches the outer diameter of the pipe and that there is no slippage after the pipe is installed. Under static load support, the weight of the pipe acts directly on the top bearing component 70. The arc-shaped bearing plate 71 fits against the bottom of the pipe, and the arc-shaped limiting housings 72 on both sides provide lateral limiting to prevent the pipe from rolling. The weight of the pipe is transferred to the support below through the bearing component 70. Component 60: Gravity is transmitted downwards through support component 60 to the telescopic part of damping component 50. Specifically, the force acts on the support connecting rod 54 and sequentially compresses the lower telescopic spring 52 through the limiting block 53. The compressed telescopic spring 52 transmits the force to the bearing part of damping component 50, and then to the lower connecting component 40. The force is transmitted through the connecting component 40 to the base component 30. The cylindrical base 31 serves as the core column, and its side reinforcing plates 32 disperse the force and enhance structural stability, preventing overturning. Finally, all the force converges to the base 10 and is safely transmitted and dispersed to the building foundation through the four corner mounting bolts 20. During dynamic vibration damping support, the vibration generated by the pipeline is transmitted through the bearing... The vibration is transmitted to the support connecting rod 54 by the component 70 and the support component 60. The vibration forces the limiting block 53 below the support connecting rod 54 to repeatedly compress and rebound the telescopic spring 52. The elastic deformation of the spring effectively absorbs and consumes the vibration energy. Due to the buffering effect of the spring, most of the vibration energy is confined inside the damping component 50. Only a very small part is transmitted downward by the smoothed force. This avoids the vibration from being transmitted to the building structure through the bracket, thereby significantly reducing the risk of noise and structural fatigue. The limiting housing 56 is connected to the annular connecting plate 55 by the fixing bolt 57 to form a protective cover to prevent the telescopic spring 52 from being excessively deformed or dislodged under severe vibration, ensuring the safety and reliability of the damping process.
