[0036] Such as Figure 1 And Figure 2As shown in the figure, the present utility model provides a truss connection node structure, which includes a chord member 1, a fixed locking sleeve 2, and at least two web member connection groups 3. The fixed locking sleeve 2 includes a first locking block 21, a second locking block 22, and a first locking assembly 23. The first locking block 21 and the second locking block 22 are relatively positioned and wrapped around the chord member 1. The first locking assembly 23 is used to apply forces to the first locking block 21 and the second locking block 22 respectively, so that the first locking block 21 and the second locking block 22 abut against the chord member 1. The fixed locking sleeve 2 is used for detachably connecting with a secondary beam; at least two web member connection groups 3 are arranged on the fixed locking sleeve 2 along the direction of surrounding the outer wall surface of the fixed locking sleeve 2; each web member connection group 3 includes at least one web member 31, and each web member connection group 3 further includes a second locking assembly 32 corresponding to the web member 31 one by one. The web member 31 is rotatably connected to the fixed locking sleeve 2 through the second locking assembly 32, and the second locking assembly 32 can apply a force to the fixed locking sleeve 2 to clamp the web member 31. In this embodiment, since the first locking block 21 and the second locking block 22 are relatively positioned and wrapped around the chord member 1 and are connected by the first locking assembly 23, and the first locking assembly 23 can apply forces to the first locking block 21 and the second locking block 22 respectively, so that the first locking block 21 and the second locking block 22 abut against the chord member 1, the fixed locking sleeve 2 can be locked on the chord member 1; since the web member 31 is rotatably connected to the fixed locking sleeve 2 through the second locking assembly 32, the connection angle between the transverse chord member 1 and the web member 31 can be adjusted by adjusting the connection angle between the web member 31 and the fixed locking sleeve 2 to be applicable to truss connections of different structural forms, greatly improving the use flexibility of the truss connection node structure; since each web member connection group 3 includes at least one web member 31, and at least two web member connection groups 3 are arranged on the outer wall surface of the fixed locking sleeve 2, the truss connection node structure can be applicable to various forms of truss structures with complex connection conditions, and the connection angles between the web members 31 and the chord member 1 can be adjusted according to the connection form of the truss structure, further improving the practicality and flexibility of the truss connection node structure. Since the fixed locking sleeve 2 is also provided with a slot for inserting the secondary beam, the fixed locking sleeve 2 can also be directly inserted and connected with the secondary beam without additionally arranging a connection structure, greatly facilitating the construction. Specifically, the chord member 1, the fixed locking sleeve 2, and each web member connection group 3 can be prefabricated in the factory and then transported to the site separately for assembly. The structure is flexible and does not require the use of large hoisting equipment for handling, greatly facilitating the construction. In this embodiment, the fixed locking sleeve 2 is provided with an insertion box 24, the insertion box 24 has a slot, and a secondary beam with a T-shaped joint at the end can be inserted into the slot to be inserted and connected with the truss connection node structure; in another embodiment, the fixed locking sleeve 2 is provided with a connection flat plate, through holes are opened on the connection flat plate, and the connection flat plate is connected with the secondary beam by bolts.

[0037] Further, as Figure 1 and Figure 2As shown, the first locking assembly 23 includes a first bolt 231 and a first nut 232. The first locking block 21 has a protruding first locking plate 211, and the second locking block 22 has a second locking plate 221 opposite to the first locking plate 211. The first bolt 231 sequentially passes through the first locking plate 211 and the second locking plate 221 and then is connected to the first nut 232. The head of the first bolt 231 abuts against the first locking plate 211, and the first nut 232 abuts against the second locking plate 221. In this embodiment, the chord 1 is a rectangular rod-shaped structure, the fixed locking sleeve 2 has a rectangular cylindrical structure, the first locking block 21 and the second locking block 22 are respectively half of the fixed locking sleeve 2, and the first locking block 21 and the second locking block 22 are arranged oppositely and connected, thereby covering and clamping the chord 1. Specifically, the edges on both sides of the first locking block 21 and the second locking block 22 respectively extend laterally to form flat first locking plates 211 and second locking plates 221. The first locking plate 211 and the second locking plate 221 can be abutted against each other, and through holes for the first bolt 231 to pass through are formed on both the first locking plate 211 and the second locking plate 221. Therefore, the first locking plate 211 and the second locking plate 221 are connected by the first bolt 231 and the first nut 232, thereby connecting and clamping the first locking block 21 and the second locking block 22 on the chord 1, and further enabling the fixed locking sleeve 2 to be tightly connected to the chord 1.

[0038] Further, as Figure 1 and Figure 3 shown, opposite first convex portion 25 and second convex portion 26 are provided on the fixed locking sleeve 2, and there is an installation gap between the first convex portion 25 and the second convex portion 26. The end of the web member 31 is arranged in the installation gap. The second locking assembly 32 includes a second bolt and a second nut. The second bolt sequentially passes through the first convex portion 25, the web member 31, and the second convex portion 26 and then is connected to the second nut. The head of the second bolt abuts against the first convex portion 25, and the second nut abuts against the second convex portion 26. In this embodiment, both the first convex portion 25 and the second convex portion 26 are plate-shaped structures protruding from the fixed locking sleeve 2, and the first convex portion 25 and the second convex portion 26 are arranged oppositely, and there is an installation gap for accommodating the end of the web member 31 between them. The second bolt sequentially passes through the first convex portion 25, the web member 31, and the second convex portion 26 and then is connected to the second nut, and the second bolt and the second nut are relatively rotated, so that the first convex portion 25 and the second convex portion 26 undergo controllable deformation to clamp the web member 31 located in the installation gap, thereby firmly fixing the web member 31. Construction workers can adjust the connection angle of the web member 31 according to the specific form and connection angle of the on-site construction truss before fixing the web member 31, so as to be applicable to different truss installation forms.

[0039] Specifically, as Figure 3As shown, the web member 31 has a lug plate 311 at the end located in the installation gap, and a lug hole for the second bolt to pass through is provided on the lug plate 311. In this embodiment, the end of the web member 31 has a lug plate 311, and a lug hole is provided on the lug plate 311, so that the connection and fixation of the web member 31 can be realized without perforating the main body of the web member 31, ensuring the reliability of the use of the web member 31.

[0040] In this embodiment, as Figure 4 shown, the web member 31 is of an integral structure, and the lug plate 311 is welded to the end of the web member 31. As Figure 5 shown, in another embodiment, the web member 31 includes a rod body 312 and an end plate provided at the end of the rod body 312, the lug plate 311 is provided on the end plate, and the end plate is bolted to the rod body 312; specifically, the end plate is provided on the fixed lock sleeve 2 through the lug plate 311, and the rod body 312 of the web member 31 is bolted to the end plate, thereby improving the flexibility of the disassembly and assembly of the rod body 31 and the fixed lock sleeve 2. When the rod body 31 is damaged and needs to be replaced, the rod body 31 can be quickly replaced by disassembling the bolts, greatly improving the practicability of the truss connection node structure.

[0041] Specifically, as Figure 5 shown, the end plate includes two symmetrically arranged buckling plates 313, the buckling plates 313 have accommodating half grooves, and the two buckling plates 313 can be joined together to form an installation groove for accommodating the end of the rod body 312; perforations for bolts to pass through are provided on both the end of the rod body 312 and the buckling plates 313. In this embodiment, each buckling plate 313 has an inwardly concave accommodating half groove, the lug plate 311 is provided on one of the buckling plates 313, or each buckling plate 313 has a part of the lug plate 311, that is, a complete lug plate 311 will be formed after the two buckling plates 313 are buckled and joined together; when the two buckling plates 313 are joined together, the two accommodating half grooves will form an installation groove, and the end of the rod body 312 can be inserted into the installation groove, and since perforations are provided on both the buckling plates 313 and the end of the rod body 312, the buckling plates 313 and the rod body 312 can be connected by bolts.

[0042] Furthermore, as Figure 1As shown, there are two web member connection groups 3, and the two web member connection groups 3 are perpendicularly arranged on the fixed locking sleeve 2. Each web member connection group 3 includes three web members 31. In this embodiment, the chord member 1 is in the shape of a rectangular parallelepiped rod structure, and correspondingly, the fixed locking sleeve 2 is also in the shape of a rectangular parallelepiped; there are two web member connection groups 3, and the two web member connection groups 3 are respectively arranged on two adjacent side surfaces of the fixed locking sleeve 2, while the insertion box 24 is arranged on another side surface of the fixed locking sleeve 2; the horizontal web member connection group 3 is used to connect the horizontal connection cross beam, and the vertical web member connection group 3 is used to connect the vertical connection upright beam, and since the insertion box 24 for inserting the secondary beam is arranged in another direction, the two web member connection groups 3 will not interfere with the secondary beam. In another embodiment, when there is no need to connect the secondary beam, the web member connection groups 3 are arranged on three adjacent side surfaces of the fixed locking sleeve 2.

[0043] Furthermore, the chord member 1 is provided with convex stripes extending along a direction perpendicular to the length direction of the chord member 1, and grooves matching the convex stripes are provided in both the first locking block 21 and the second locking block 22. The convex stripes are clamped in the grooves. In this embodiment, the chord member 1 is connected by being wrapped and locked by the fixed locking sleeve 2. The chord member 1 is provided with convex stripes, and the extending direction of the convex stripes is perpendicular to the length direction of the chord member 1. Grooves matching the convex stripes are opened on the inner side walls of both the first locking block 21 and the second locking block 22; specifically, when using the fixed locking sleeve 2 to connect the chord member 1, first wrap the first locking block 21 around the chord member 1 and make the convex stripes of the chord member 1 clamped in the grooves of the first locking block 21, then wrap the second locking block 22 around the chord member 1 and also make the other half of the convex stripes of the chord member 1 clamped in the grooves of the second locking block 22, and then use the first locking assembly 23 to tightly connect and clamp the first locking block 21 and the second locking block 22 on the chord member 1; the clamping of the convex stripes and the grooves further improves the firmness and reliability of the connection between the fixed locking sleeve 2 and the chord member 1.

[0044] As Figure 6 shown, in one embodiment, each web member connection group 3 includes three web members 31, and the three web members 31 can all be fixed between the first convex portion 25 and the second convex portion 26 through the second bolts and second nuts, that is, the three web members 31 are all hingedly connected to the fixed locking sleeve 2; in another embodiment, a first cylinder is provided on the first convex portion 25, and a second cylinder corresponding to the first cylinder is provided on the second convex portion 26. When the first convex portion 25 and the second convex portion 26 are connected, the first cylinder and the second cylinder are combined to form a sleeve 27. The sleeve 27 is used to accommodate the middle web member 31 of the web member connection group 3, and through holes are opened on both the first cylinder and the second cylinder. Therefore, by connecting the first cylinder and the second cylinder with bolts and nuts, the middle web member 31 can be fixedly connected in the sleeve 27, while the web members 31 on the other two sides are still hingedly connected to the fixed locking sleeve 2.

[0045] Obviously, the above embodiments of the present utility model are merely examples for clearly illustrating the present utility model, rather than limitations on the implementation manners of the present utility model. For those of ordinary skill in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present utility model.
