Description

Technical Field

[0001] This utility model belongs to the field of building electromechanical installation technology, specifically relating to a double-layer air duct support inside a steel structure pipe truss. Background Technology

[0002] As an important component of building HVAC systems, duct supports have evolved from simple angle steel hangers to modern modular vibration-damping supports. Traditional supports often employ rigid connections, which in large-span applications such as steel trusses often suffer from low installation accuracy, poor seismic performance, and difficulty in adjustment. With increasingly complex building structures and higher requirements for vibration damping in electromechanical systems, modern duct support technology is gradually developing towards modularity, adjustability, and high seismic resistance. Currently, it is mainly used in air conditioning and ventilation systems of large-space buildings such as stadiums, airport terminals, and convention centers, especially in double-layer duct layouts. These systems must simultaneously meet requirements for structural stability, ease of installation, and operational vibration damping to cope with the dynamic load challenges of thermal expansion and contraction and airflow vibration during long-term operation.

[0003] Traditional rigid supports are unable to effectively absorb the vibration energy generated during the operation of duct systems, leading to loosening of connections and noise. Fixed structures cannot adapt to the spatial variation requirements of steel duct trusses, making adjustment difficult and lacking in precision when installing double-layer ducts. At the same time, most supports lack modular design, making disassembly and assembly inconvenient and difficult to reuse, increasing construction and maintenance costs. Utility Model Content

[0004] The purpose of this utility model is to provide a double-layer air duct support inside a steel structure truss, which aims to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A double-layer duct support inside a steel structure tubular truss includes,

[0007] The support foot, the support rod fixedly mounted on the side wall of the support foot, the fixing bolt threaded to the surface of the support rod, the mounting assembly disposed on the surface of the support rod, and the connecting assembly disposed on the surface of the mounting assembly for use with the mounting assembly.

[0008] As a preferred embodiment of the present invention, the mounting assembly includes a mounting plate sleeved on the surface of the support rod, and a slot provided on the side wall of the mounting plate.

[0009] As a preferred embodiment of the present invention, the mounting assembly further includes a mounting groove disposed on the side wall of the mounting plate, and a bottom cylinder inserted into the inner wall of the mounting groove.

[0010] As a preferred embodiment of the present invention, the mounting assembly further includes a top spring fixedly connected to the side wall of the mounting plate, and a sliding groove disposed on the side wall of the bottom cylinder.

[0011] As a preferred embodiment of this utility model, the connecting assembly includes a retaining ring fixedly connected to the end of the top spring, and a limiting rod inserted into the inner wall of the retaining ring.

[0012] As a preferred embodiment of the present invention, the connecting assembly further includes a sleeve movably connected to the surface of the retaining ring, and a movable column sleeved on the inner wall of the sleeve.

[0013] As a preferred embodiment of the present invention, the connecting assembly further includes a mounting bracket fixedly installed on the surface of the movable column, and a support roller connected to the side wall of the mounting bracket via a bearing.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: Through the installation and connection components, the duct support system achieves rapid installation and height adjustment. The loose connection between the support rod and the mounting plate, combined with the fixing bolts, allows for flexible adjustment of the overall height of the support, adapting to different truss space requirements. The top spring and bottom cylinder in the installation component form an elastic buffer structure, effectively absorbing vibration energy during duct operation, reducing noise and extending the duct's service life. The connection component uses a combination of snap rings and limit rods to achieve fine-tuning of height. The sliding structure of the sleeve and the moving column allows the support roller to adapt to duct displacement. The bearing-connected support roller ensures a tight fit during duct thermal expansion and contraction, guaranteeing support rigidity while providing excellent shock absorption performance. Furthermore, all components are disassembled and reused, reducing construction and maintenance costs. Attached Figure Description

However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0023] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0024] Example

[0025] Reference Figures 1-4 This embodiment of the present invention provides a double-layer duct support inside a steel structure truss, comprising:

[0026] The support foot 101, the support rod 102 fixedly installed on the side wall of the support foot 101, the fixing bolt 103 threadedly connected to the surface of the support rod 102, the mounting assembly 104 provided on the surface of the support rod 102, and the connecting assembly 105 provided on the surface of the mounting assembly 104 for use with the mounting assembly 104.

[0027] Specifically, the mounting assembly 104 includes a mounting plate 104a sleeved on the surface of the support rod 102, and a slot 104b provided on the side wall of the mounting plate 104a. The mounting assembly 104 also includes a mounting groove 104c provided on the side wall of the mounting plate 104a, and a bottom cylinder 104d inserted into the inner wall of the mounting groove 104c. The mounting assembly 104 also includes a top spring 104e fixedly connected to the side wall of the mounting plate 104a, and a sliding groove 104f provided on the side wall of the bottom cylinder 104d.

[0028] Furthermore, the top spring 104e facilitates the dispersal of duct vibrations to the mounting plate 104a of the device during duct operation, ensuring the stability of the duct during operation.

[0029] Preferably, the connecting assembly 105 includes a retaining ring 105a fixedly connected to the end of the top spring 104e, and a limiting rod 105b inserted into the inner wall of the retaining ring 105a. The connecting assembly 105 also includes a sleeve 105c movably connected to the surface of the retaining ring 105a, and a movable column 105d sleeved on the inner wall of the sleeve 105c. The connecting assembly 105 also includes a mounting bracket 105e fixedly installed on the surface of the movable column 105d, and a support roller 105f connected to the side wall of the mounting bracket 105e by a bearing.

[0030] It should be noted that the support roller 105f facilitates the connection between the device and the air duct. The support roller 105f, used in conjunction with the mounting bracket 105e, can ensure the stability of the air duct support, while also facilitating the disassembly of the device and ensuring its multiple uses.

[0031] When in use, place the device in the designated position, turn the bolt on the limit rod 105b, adjust the height of the retaining ring 105a (which works in conjunction with the housing 105c), adjust the height of the moving column 105d, and install the air duct on the support roller 105f. When the air duct is running, the vibration generated will act on the mounting frame 105e, which will transmit the force of the vibration to the moving column 105d. The moving column 105d will then transmit the force to the top spring 104e, which will evenly distribute the force of the vibration to the surface of the mounting plate 104a. The groove 104b on the surface of the mounting plate 104a is movably connected to the support rod 102 and is connected by the fixing bolt 103 to ensure stable support of the support foot 101 and the support rod 102.

[0032] In summary, the stable main support structure, consisting of support feet 101, support rods 102, and fixing bolts 103, combined with the installation components 104 and connecting components 105, achieves efficient vibration reduction and flexible adjustment of the duct. The mounting plate 104a is loosely connected to the support rod 102 via slots 104b. Combined with the elastic buffering characteristics of the top spring 104e, the vibrations during duct operation are evenly distributed to the mounting plate 104a, effectively reducing the risk of resonance. The design of the bottom cylinder 104d and the sliding groove 104f further enhances... The adaptability of the installation component 104 is enhanced. The engagement of the retaining ring 105a and the limiting rod 105b in the connecting component 105 allows for quick height adjustment. The sliding structure of the housing 105c and the moving column 105d enables the mounting frame 105e to dynamically respond to duct displacement. The support roller 105f, connected by bearings, ensures smooth duct sliding and facilitates disassembly and maintenance. The device combines rigid support with flexible shock absorption. The installation process is simple and reusable, improving the stability and durability of the duct system in steel structure truss environments.
