Description

Technical Field

[0001] This utility model relates to the field of tubular truss reinforcement, specifically to a novel device for lateral stabilization reinforcement of tubular truss chords, which is mainly applicable to the reinforcement of circular tubular trusses. Background Technology

[0002] Tubular trusses, as a commonly used form of steel structure, are widely used in the construction of bridges, factories, and large stadiums due to their advantages such as lightweight, strong span capacity, and ease of installation. However, in some special scenarios, such as when a heavier load is added to the roof or when external forces increase, the chords of the tubular truss are prone to out-of-plane instability, seriously affecting the safety and reliability of the structure. Current reinforcement solutions typically involve direct welding or the addition of supporting structures, but these methods not only significantly damage the integrity of the original structure but also require complex construction techniques and high modification costs. Furthermore, welded connections may lead to material degradation or stress concentration, further increasing the difficulty and potential risks of construction.

[0003] While existing technologies have addressed chord stability issues to some extent, they generally suffer from low construction efficiency, complex installation processes, and high maintenance costs, making it difficult to meet the demands of modern buildings for rapid and economical structural reinforcement. Therefore, the market urgently needs a more efficient, economical, and convenient lateral stabilization reinforcement device for tubular truss chords to optimize structural stress performance, reduce damage to existing structures, and improve the applicability and operability of reinforcement solutions. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a new type of device for lateral stabilization reinforcement of tubular truss chords. This device can improve the lateral stability of tubular truss chords without damaging the original structure, avoid out-of-plane instability, and has the characteristics of simple installation, efficient construction and economical maintenance. It is suitable for reinforcement needs in existing structure renovation and new construction projects.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a novel device for lateral stabilization and reinforcement of tubular truss chords, including a main truss, a support pipe, a connecting plate, and fasteners; the support pipe is fixedly connected to the main truss through the connecting plate and fasteners; the connecting plate is composed of two arc-shaped clamping plates; the fasteners are detachable.

[0006] Furthermore, the length of the support tube can be adjusted according to the reinforcement requirements of the main truss to meet the needs of different spans.

[0007] Furthermore, the support tube has thickened ends at both ends, which are connected to the connecting plate by a hinge, thereby achieving flexibility for multi-angle installation and ensuring uniform force distribution.

[0008] Furthermore, the connecting plate consists of two semi-circular arc-shaped clamping plates. The inner surfaces of the two clamping plates are provided with anti-slip textures to enhance the fit with the main truss and prevent slippage. The two clamping plates are connected and tightly fixed by fasteners to form a structure that hugs the main truss.

[0009] Furthermore, the fastener includes a bolt, a nut, and a limiting washer. The bolt passes through a through hole in the connecting plate and is locked in place with the nut. The limiting washer is positioned between the bolt head and the connecting plate. The inner surface of the limiting washer is provided with annular anti-slip teeth to improve the fastening effect and prevent loosening.

[0010] The beneficial effects of this utility model are:

[0011] This invention improves the lateral stability of the truss chord. By using the support tube and connecting plate together, it significantly enhances the bending stiffness of the chord and the overall structural stability, and reduces the risk of out-of-plane instability of the chord.

[0012] This utility model is easy to install and disassemble, and adopts a detachable fastener design. It does not require complicated construction processes, and can quickly complete on-site installation and subsequent disassembly and maintenance, reducing construction difficulty and time costs.

[0013] This utility model is highly adaptable. Through the adjustable length design of the support tube and the hinged connection method, it can adapt to truss structures with different spans and angles, making reinforcement more flexible and suitable for various engineering needs.

[0014] This invention improves the fastening reliability of the device. The anti-slip texture design on the inner surface of the connecting plate and the annular anti-slip teeth of the limiting washer further enhance the fixing effect between the support tube and the main truss, effectively preventing loosening or slippage.

[0015] This utility model protects the original structure and achieves a non-welding connection through an arc-shaped clamp plate, avoiding the damage that direct welding may cause to the main truss, improving safety and applicability, and is particularly suitable for renovation projects of existing structures.

[0016] This invention reduces construction costs, features a simple device design, uses standardized components and modular installation, requires no additional complex processing or special equipment, is economical and efficient, and has high promotional value.

[0017] This invention facilitates subsequent inspection and maintenance. The device adopts a detachable design, which makes it easy to regularly inspect and replace fasteners and connecting structures, extending the service life of the device and ensuring long-term reinforcement effect.

[0018] This invention has a wide range of applications. It is not only suitable for the reinforcement and renovation of existing tubular trusses, but also for new construction projects where lateral stability needs to be improved.

[0019] This invention optimizes the stress distribution of the structure. By thickening the ends and using a hinged design, the lateral force is effectively and evenly distributed to the main truss and support pipe, which improves the reinforcement effect and extends the service life of the device and the main truss.

[0024] The present invention will now be further described with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention in a schematic manner, and therefore only show the components relevant to the present invention.

[0025] In order to achieve the purpose of this utility model, such as Figure 2 and Figure 1 As shown, the lateral stabilization and reinforcement device for the truss chord of this utility model includes a main truss 1, a support pipe 2, a connecting plate 3, and fasteners 4. Figure 2 As shown, the lateral stability of the chord members in the reinforced main truss 1 is insufficient, making it prone to out-of-plane instability when subjected to large loads or lateral disturbances. This can be addressed by installing support pipes 2, connecting plates 3, and fasteners 4. Figure 1 As shown, the reinforced main truss chords form a lateral support structure, which significantly improves the stability and stress performance of the truss.

[0026] like Figure 1 As shown, the support pipe 2 has thickened ends at both ends and is connected to the connecting plate 3 by hinges to accommodate installation requirements at different angles. The connecting plate 3 consists of two semi-circular arc-shaped clamp plates with anti-slip textures on their inner surfaces to enhance the connection stability with the main truss 1. The fasteners 4 include bolts, nuts, and limiting washers. The bolts are locked to the nuts through through holes in the connecting plate 3, and the annular anti-slip teeth of the limiting washers effectively improve anti-slip ability and ensure the robustness of the device.

[0027] To achieve efficient installation and adapt to diverse construction needs, such as Figure 3 As shown, the length of the support pipe 2 can be adjusted according to the actual reinforcement requirements of the main truss 1. The arc-shaped clamping plate structure of the connecting plate 3 matches the height of the circular chord section of the main truss 1, providing a stable connection with uniform stress. At the same time, the fastener 4 adopts a standardized bolt structure, which has high rust resistance and tensile strength, and is suitable for long-term use in steel structure environments.

[0028] The installation method is as follows:

[0029] Installation location confirmation: Based on the design requirements, determine the location of the chord nodes of the main truss 1 that need to be reinforced.

[0030] Connection plate installation: Secure the two arc-shaped clamp plates in the connection plate 3 to the outer surface of the chord of the main truss 1, and initially fix them with fasteners 4.

[0031] Support tube installation: Adjust the length of the support tube 2 according to the node position so that both ends are aligned with the corresponding mounting holes of the connecting plate 3, and connect and lock them by hinge.

[0032] Overall reinforcement: Tighten all bolts and nuts at the joints, ensure that the annular anti-slip teeth of the limit washer fits the surface of the connecting plate 3, and check the firmness of the device.

[0033] After reinforcement is completed, such as Figure 1 As shown, the chords of the main truss 1 and the support tube 2 together form an optimized overall load-bearing structure, significantly improving the bending stiffness and lateral stability of the chords and reducing mid-span deformation. At the same time, the device has a simple structure, is quick to install, requires no welding or complex construction, and greatly reduces construction difficulty and cost.

[0034] The above embodiments are only for illustrating the technical concept and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it. They should not be used to limit the protection scope of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the protection scope of this utility model.
