Description

Technical Field

[0001] This utility model relates to the field of public building technology, specifically to an adjustable concrete hollow truss internal pipeline support. Background Technology

[0002] In public buildings, especially in projects involving concrete hollow truss structures, the support and vibration reduction of pipelines has been a long-standing technical challenge. Concrete hollow trusses, due to their unique structural form, provide space for pipeline installation.

[0003] Currently, most common pipeline supports are rigidly fixed using welded steel sections or bolts. These traditional supports have relatively fixed installation positions, cannot be flexibly adjusted, and are difficult to adapt to unavoidable structural dimensional errors on construction sites. They are also prone to crossing and colliding with other professional pipelines or cable trays, leading to installation difficulties and even requiring later cutting and modification, affecting structural safety and increasing costs. Secondly, rigid supports directly transmit the vibration of the pipeline to the main structure, which not only generates noise, but when the natural frequency of the truss structure couples with the frequency of the fluid inside the pipe, it may cause resonance in the entire pipeline system and even local structures, creating safety hazards. Based on this, this utility model designs an adjustable concrete hollow truss pipeline support to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide an adjustable concrete hollow truss internal pipeline support, which solves the problems of inflexible adjustment and resonance in the prior art.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: An adjustable concrete hollow truss internal pipeline support, comprising: A truss clamping assembly is used to fix the upper and lower chord beams of a concrete hollow truss. The truss clamping assembly includes an upper clamp and a lower clamp, which are used to clamp the upper and lower surfaces of the truss beam, respectively. Both the upper clamp and the lower clamp include a clamping frame. The frame wall of the clamping frame has a threaded hole. A threaded rod is threaded into the inner cavity of the threaded hole. A clamping plate is rotatably connected to one end of the threaded rod located in the inner cavity of the clamping frame for clamping and fixing the upper and lower chord beams.

[0006] An adjustment assembly, disposed between the truss clamping assemblies located at the top and bottom, is used for height and width adjustment.

[0007] A pipe support assembly is mounted on the front and back of the adjustment assembly. The pipe support assembly includes a damper for dissipating the vibration energy of the pipeline.

[0008] Preferably, a telescopic rod is installed between the clamping plate and the inner wall of the clamping frame. The telescopic rod is distributed in multiple matrix arrays. The threaded rod is rotatably connected to the clamping plate through a bearing. A crank is installed on the outside of the clamping frame for rotating the threaded rod.

[0009] Preferably, the adjustment assembly includes an adjustment rod fixedly connected to the front of the clamping frame, and a support rod is also installed on the outer ring of the adjustment rod and the adjustment rod is slidably connected in the inner cavity of the support rod. Limiting holes are opened on the front of both the adjustment rod and the support rod, and multiple sets of limiting holes are distributed in a linear array. Limiting bolts are also installed in the inner cavity of the limiting holes.

[0010] Preferably, the adjustment assembly further includes a load-bearing beam fixedly connected to one side of the support rod, and a reinforcing rib is installed between the support rod and the load-bearing beam. A sleeve rod is also installed between the load-bearing beams on both sides and is slidably connected to the outer ring of the load-bearing beam. The top of the sleeve rod and the load-bearing beam are provided with fixing holes, which are distributed in multiple linear arrays. Fixing bolts are installed in the inner cavity of the fixing holes.

[0011] Preferably, the tube support assembly includes spherical hinge joints installed on the front and back of the sleeve rod, and fastening bolts are installed on the outer ring of each spherical hinge joint for fixing the angle of the spherical hinge joint. A bracket is installed on the side of the spherical hinge joint away from the sleeve rod.

[0012] Preferably, a lower fixing ring is fixedly connected to the inner cavity of the bracket, and an upper fixing ring is hinged to the top of the lower fixing ring. The damper is fixedly connected to the inner walls of the lower fixing ring and the upper fixing ring, and both the upper fixing ring and the lower fixing ring are distributed in multiple linear arrays.

[0013] Compared with the prior art, the beneficial effects achieved by this utility model are: 1. The threaded rod and clamping plate structure in the truss clamping assembly of this utility model allows for fine adjustment of the clamping force, which can adapt to the deviation of the actual size of the concrete truss beam. The adjustment assembly realizes the segmented adjustment of the support system in vertical height and horizontal span through the sliding cooperation between the adjustment rod and the support rod, and the telescopic structure between the sleeve rod and the load-bearing beam.

[0014] 2. The ball joint of this utility model provides multi-dimensional angle adjustment capability for the pipeline in the installation posture, ensuring that the pipeline is in the optimal stress state, while the damper fixed to the inner wall of the upper and lower fixing rings can effectively absorb and dissipate vibration energy through its own deformation when the pipeline vibrates.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please refer to Figures 1-5 An adjustable concrete hollow truss internal pipeline support, comprising: A truss clamping assembly 1 is used to fix the upper and lower chord beams of a concrete hollow truss. The truss clamping assembly 1 includes an upper clamp 101 and a lower clamp 102, which are used to clamp the upper and lower surfaces of the truss beams, respectively. Both the upper clamp 101 and the lower clamp 102 include a clamping frame 103. The frame wall of the clamping frame 103 has a threaded hole 104. A threaded rod 105 is threaded into the inner cavity of the threaded hole 104. A clamping plate 106 is rotatably connected to one end of the threaded rod 105 located in the inner cavity of the clamping frame 103 for clamping and fixing the upper and lower chord beams. An adjusting assembly 2 is set between the truss clamping assemblies 1 located at the top and bottom for adjusting the height and width. A pipe support assembly 3 is installed on the front and back of the adjusting assembly 2. The pipe support assembly 3 includes a damper 301 for absorbing the vibration energy of the pipeline.

[0019] A telescopic rod 107 is installed between the clamping plate 106 and the inner wall of the clamping frame 103. The telescopic rod 107 is distributed in multiple matrix arrays. The threaded rod 105 is rotatably connected to the clamping plate 106 through a bearing. A crank is installed on the outside of the clamping frame 103 for rotating the threaded rod 105.

[0020] The adjustment assembly 2 includes an adjustment rod 201 fixedly connected to the front of the clamping frame 103. A support rod 202 is also installed on the outer ring of the adjustment rod 201, and the adjustment rod 201 is slidably connected in the inner cavity of the support rod 202. Limiting holes 203 are opened on the front of both the adjustment rod 201 and the support rod 202, and multiple sets of limiting holes 203 are distributed in a linear array. Limiting bolts 204 are also installed in the inner cavity of the limiting holes 203.

[0021] The adjustment assembly 2 also includes a load-bearing beam 205 fixedly connected to one side of the support rod 202. A reinforcing rib is also installed between the support rod 202 and the load-bearing beam 205. A sleeve rod 206 is also installed between the load-bearing beams 205 on both sides and the sleeve rod 206 is slidably connected to the outer ring of the load-bearing beam 205. Fixing holes 207 are opened at the top of both the sleeve rod 206 and the load-bearing beam 205. The fixing holes 207 are distributed in multiple linear arrays. Fixing bolts 208 are installed in the inner cavity of the fixing holes 207.

[0022] In this embodiment of the invention, the vertical height and horizontal width are adjusted by adjusting component 2. Vertical adjustment is achieved by sliding the adjusting rod 201 within the cavity of the support rod 202. Once the height is determined, the limiting bolt 204 is inserted into the aligned limiting hole 203 to fix the height. Horizontal adjustment is achieved by sliding the sleeve rod 206 on the load-bearing beam 205. After adjusting to the required span, the fixing bolt 208 is inserted into the aligned fixing hole 207 for fixation.

[0023] Please refer to Figures 1-5 The tube support assembly 3 includes spherical hinge joints 307 installed on the front and back of the sleeve rod 206. Each spherical hinge joint 307 has a fastening bolt 302 installed on its outer ring for fixing the angle of the spherical hinge joint 307. A bracket 303 is installed on the side of the spherical hinge joint 307 away from the sleeve rod 206.

[0024] A lower fixing ring 304 is fixedly connected in the inner cavity of the bracket 303. An upper fixing ring 305 is hinged to the top of the lower fixing ring 304. A damper 301 is fixedly connected to the inner walls of the lower fixing ring 304 and the upper fixing ring 305. Both the upper fixing ring 305 and the lower fixing ring 304 are distributed in multiple linear arrays.

[0025] In this embodiment of the invention, the dampers 301 are arranged in a linear array on the inner walls of the upper fixed ring 305 and the lower fixed ring 304. This arrangement allows the damping force to act evenly on the outer circumference of the pipeline, providing comprehensive constraint and damping effects, and effectively suppressing the vibration of the pipeline in multiple dimensions. The spherical hinge joint 307 provides rotational degrees of freedom around multiple axes, enabling the pipe support assembly 3 to perform angular compensation in any direction. This not only eliminates installation stress but also helps to disperse dynamic loads, further improving the fatigue resistance and safety of the entire support system during long-term operation.

[0026] In use, the entire support system is first fixed to the upper and lower chord beams of the concrete hollow truss using the truss clamping assembly 1. The operator rotates the threaded rods 105 on the outside of the clamping frame 103 in the upper clamp 101 and lower clamp 102, pushing the clamping plate 106 towards the truss beam surface via threaded transmission until the clamping plate 106 is tightly fitted against the beam surface, achieving a secure clamping. The telescopic rods 107, distributed in a matrix array between the clamping plate 106 and the inner wall of the clamping frame 103, act as guides and supports during clamping, ensuring the parallel movement of the clamping plate 106 and preventing skewing.

[0027] The vertical height and horizontal width are adjusted by adjusting component 2. Vertical adjustment is achieved by sliding the adjusting rod 201 within the cavity of the support rod 202. Once the height is determined, the limiting bolt 204 is inserted into the aligned limiting hole 203 to fix the height. Horizontal adjustment is achieved by sliding the sleeve rod 206 on the load-bearing beam 205. After adjusting to the required span, the fixing bolt 208 is inserted into the aligned fixing hole 207 for fixation.

[0028] The pipeline is placed within the bracket 303 and secured by hinged upper and lower retaining rings 305 and 304. Dampers 301, linearly arrayed on the inner wall of the retaining rings, directly contact the pipeline surface to dissipate vibrational energy generated by fluid pulsation or external excitation, preventing vibration from being transmitted to the truss structure. By loosening the fastening bolts 302 on the spherical hinge joint 307, the installation angle of the bracket 303 and pipeline can be finely adjusted to ensure pipeline alignment and conformity to its direction. After adjustment, tightening the fastening bolts 302 locks the angle.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit, the scope of which is defined by the appended claims and their equivalents.
