Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to a truss connection node. Background Technology

[0002] Steel trusses offer advantages such as a simple load-bearing system, flexible structural layout, and light weight, making them widely applicable to large stadiums, exhibition halls, and large factories. They are also commonly used for the roofs of temporary roadshow and exhibition halls. Traditionally, there are two main methods for connecting two sections of steel trusses: one involves on-site welding of the two trusses, which requires hot work, resulting in low construction efficiency, and the welded joints are non-removable and difficult to reuse; the other involves using a connecting plate with bolts to splice the two trusses, where the two sides of the connecting plate are bolted to the two trusses at a single connection point, requiring at least two bolt connections. While this facilitates disassembly, the use of multiple bolts also leads to low construction efficiency. Utility Model Content

[0050] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0051] The following is combined with Figures 1-5 The following describes embodiments of the present invention.

[0052] According to an embodiment of this utility model, a truss connection node is provided, such as... Figure 1 , Figure 2 , Figure 3 As shown, it includes: a first truss 1, a second truss 2, and fasteners 3.

[0053] The first truss 1 has at least one first connecting portion 1021 at its end, which extends away from the end of the first truss 1; the second truss 2 has at least one first connecting mating portion 2011 at its end, which is the same number as the first connecting portion 1021 and is positioned accordingly; when the first truss 1 and the second truss 2 are connected, the first connecting portion 1021 can cover the first connecting mating portion 2011; the fastener 3 is detachably connected between the first connecting portion 1021 and the first connecting mating portion 2011 to connect the first truss 1 and the second truss 2.

[0054] In the above embodiment, a first connecting portion 1021 extending away from its end is provided on the first truss 1, and a first connecting mating portion 2011 that connects and engages with the first connecting portion 1021 is provided on the second truss 2. The first truss 1 and the second truss 2 are then fixedly connected by a detachable fastener 3. In this way, no on-site welding is required during truss connection construction. Moreover, at a single connection point, the first connecting portion 1021 of the first truss 1 and the first connecting mating portion 2011 of the second truss 2 can be connected on-site using fasteners 3 to fix the two truss sections. This improves the construction efficiency of truss connection operations and enables rapid installation and dismantling, facilitating the reuse of the truss.

[0055] Specifically, when the first truss 1 and the second truss 2 are connected, the first connecting part 1021 of the first truss 1 approaches the second truss 2 until the first connecting part 1021 covers the first connecting mating part 2011, and then the first connecting part 1021 and the first connecting mating part 2011 are fixedly connected by fasteners 3; when the first truss 1 and the second truss 2 are disassembled, it is only necessary to remove the fasteners 3 at the first connecting part 1021 and the first connecting mating part 2011 to realize the disassembly of the first truss 1 and the second truss 2.

[0056] Furthermore, the truss connection node provided in this embodiment is applicable to both vertical and unidirectional connections of two truss sections, requiring only reasonable adjustment of the positions of the first connection part 1021 and the first connection mating part 2011.
