[0002] Steel truss assemblies are structural components made of steel bars and other metal materials. They are mainly used in building construction, bridges, roads, tunnels, and other projects as support, load-bearing, and structural reinforcement components. In order to enable truss assemblies to be quickly installed on site without complicated welding or bolting connections, snap-fit ​​steel truss assemblies are required. Construction workers only need to align and fix the snap-fit ​​parts to quickly complete the assembly of the components, thereby saving a lot of construction time and shortening the project schedule.

[0003] Snap-fit ​​steel truss assemblies can be divided into several types, including unidirectional snap-fit ​​steel trusses, bidirectional snap-fit ​​steel trusses, and multi-layer snap-fit ​​steel trusses. There are many types of snap-fit ​​steel truss assemblies, and the appropriate type can be selected according to different load-bearing requirements, construction requirements, and structural complexity. Among them, unidirectional snap-fit ​​steel trusses are connected to the truss in a single direction through snap-fit, and are usually used for structures that bear unidirectional loads, such as bridges and floor slabs.

[0004] Existing steel truss connection methods typically rely on a large number of bolts and fasteners to complete the connection. This traditional connection method requires a lot of manual intervention and complex tool operation, which is not only inefficient, but also prone to problems such as instability and misalignment during installation, thereby affecting the overall structural performance of the steel truss and increasing the complexity and cost of construction. Utility Model Content

[0032] 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.

[0033] Reference Figures 1-3 The present invention provides an embodiment of a snap-fit ​​steel truss assembly, including an mounting plate 1, a truss 2 on the top of the mounting plate 1, and a connecting component on the outer wall of the truss 2. The connecting component is used to connect the truss 2 and the mounting plate 1 to ensure its stability and firmness.

[0034] The connecting assembly includes connector 3, which engages with truss 2 to fasten and secure truss 2, preventing it from shifting or detaching during use. Connecting buckles 4 are fixedly connected to both sides of connector 3, providing connection points for securing other components to truss 2. Connector 5 is located at the top of connector 3, and hook 6 is fixedly connected to its bottom. A limit component is located on one side of hook 6 to further ensure a firm connection between hook 6 and connecting buckle 4, preventing hook 6 from loosening during use. The engagement of hook 6 and connecting buckle 4 provides a stable connection interface, enhancing the overall strength of the assembly. A wing bolt 9 is internally threaded into connecting buckle 4, and a pressure plate 8 is rotatably connected to the bottom of wing bolt 9. A connecting assembly is located at the bottom of pressure plate 8 for further fastening and stabilizing truss 2. The limit component includes a stop block 7, which is fixedly connected to the top of hook 6 on one side. This prevents hook 6 from excessively sliding or detaching from connecting buckle 4, ensuring hook 6 remains in the correct position and increasing connection reliability. The connecting component includes a limiting block 10, the top of which is fixedly connected to the bottom of the wing bolt 9, and the limiting block 10 is rotatably connected inside the pressure plate 8. The limiting block 10 prevents the wing bolt 9 from excessive friction when rotating.

[0035] Specifically, firstly, connector 3 is aligned with the connection point of truss 2, ensuring a secure fastening between connector 3 and truss 2. Next, connector 5 is fastened into connector buckle 4 via hook 6, ensuring hook 6 is securely locked within buckle 4. To prevent hook 6 from accidentally slipping out during use, a stop block 7 on one side of hook 6 ensures hook 6 is firmly fixed within buckle 4, increasing the safety and stability of the entire assembly process. Subsequently, by rotating the wing bolt 9 through the built-in limit block 10, pressure plate 8 is rotated and pressed down, with pressure plate 8 applying uniform pressure to tighten truss 2, ensuring a secure connection with connector 5.

[0036] Reference Figure 4 and Figure 5A connecting seat 11 is fixedly connected to the top of the mounting plate 1. A rotating shaft 12 is fixedly connected inside the connecting seat 11, and a clamping plate 13 is rotatably connected to the outer wall of the rotating shaft 12. The rotating shaft 12 allows the clamping plate 13 to rotate freely in a fixed position, making installation and disassembly more convenient and adaptable to different installation angles, providing flexibility. The clamping plate 13 fits into the outer wall of the truss 2. The design of the clamping plate 13 allows it to fit tightly with the truss 2, ensuring a stable connection between the truss 2 and the mounting plate 1. Connecting blocks 16 are rotatably connected to one side of both the connecting seat 11 and the clamping plate 13. The connecting blocks 16 provide a connection interface between the clamping plate 13 and other components, allowing the clamping plate 13 to be stably fixed together with the connecting blocks 16 through rotational connection. A telescopic rod 17 is provided between the connecting blocks 16. The telescopic rod 17 is adjustable in length, allowing the fixed distance between the clamping plate 13 and the truss 2 to be adjusted according to actual needs, ensuring stable installation of trusses 2 of different sizes. A tension spring 18 is fitted onto the outer wall of the telescopic rod 17. The tension spring 18 provides a reaction force through its elasticity, enabling the telescopic rod 17 to maintain appropriate tension under load, thereby ensuring that the clamping plate 13 is always tightly fitted to the outer wall of the truss 2. Both ends of the telescopic rod 17 and the tension spring 18 are fixedly connected between the connecting blocks 16, enhancing the fixing stability of the clamping plate 13. An installation groove 14 is provided inside the clamping plate 13, providing space suitable for bolt fixing, allowing the fastening bolts 15 to effectively connect the clamping plate 13 to the truss 2, ensuring a more stable connection. A fastening bolt 15 is provided at the top of the clamping plate 13, which engages with the installation groove 14. Through the tightening action of the bolt, the connection strength between the clamping plate 13 and the truss 2 is further enhanced, ensuring that the truss 2 will not loosen or fall off during use.

[0037] Specifically, the truss 2 is embedded between the clamping plates 13, ensuring its stable position and tight fit with the clamping plates 13. The clamping plates 13 are connected to the connecting seat 11 via the pivot 12, allowing the clamping plates 13 to rotate flexibly for precise adjustment during installation. To ensure that the clamping plates 13 are firmly attached to the outer wall of the truss 2 during installation, the clamping plates 13 are connected by a tension spring 18. The tension of the tension spring 18 keeps the clamping plates 13 tightly attached to the outer wall of the truss 2, effectively preventing loosening between the clamping plates 13 and the truss 2 during installation. Next, by embedding the fastening bolts 15 into the mounting grooves 14 on the clamping plates 13, the clamping plates 13 are further securely locked in place, ensuring that the clamping plates 13 are tightly fixed to the mounting plate 1, thereby achieving a stable installation of the truss 2.

[0038] Working principle: When using this snap-fit ​​steel truss assembly, firstly, when truss 2 is assembled, connector 3 is fastened to truss 2. Then, connector 5 is fastened into connector buckle 4 through hook 6. At the same time, hook 6 is limited by stop block 7 to prevent it from slipping out of connector buckle 4. Then, rotate wing bolt 9 to extend into connector 5. Wing bolt 9 rotates in pressure plate 8 through limit block 10. Wing bolt 9 drives pressure plate 8 to press down and tightly adhere to truss 2. At the same time, connector 3 and connector 5 abut against each other to connect. This achieves the effect of facilitating the connection of truss 2 and adapting to different sizes.

[0039] When the truss 2 is assembled with the mounting plate 1, the truss 2 is embedded between the clamping plates 13. The clamping plates 13 rotate in the connecting seat 11 through the pivot 12. At the same time, the clamping plates 13 are tightly pressed against the outer wall of the truss 2 by the tension of the tension spring 18. Then, the fastening bolts 15 are embedded in the mounting grooves 14 on the clamping plates 13 to engage the clamping plates 13, thereby fixing the clamping plates 13 to the truss 2 on the mounting plate 1, achieving the effect of facilitating the installation of the truss 2.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
