Description

Technical Field

[0001] This utility model relates to the field of trusses, specifically a spliced ​​steel structure truss. Background Technology

[0002] A steel truss is a stable frame structure consisting of several members connected by welding, riveting, or bolting, forming a triangular or geometrically stable frame. Trusses are classified into various types, such as triangular trusses, parallel chord trusses, and parabolic trusses.

[0003] Trusses can be fixed and spliced ​​in various ways. For example, patent number CN221721907U includes five arc-shaped frames. Each arc-shaped frame has three slots on its left and right sides. Four plug-in components are set between the five arc-shaped frames. A load-bearing component is set at the bottom of each arc-shaped frame. Clamping components are set at the front and rear ends of the five arc-shaped frames respectively. Through the cooperation of the slots, plugs, connecting plates and reinforcing plates, the arc-shaped frames can be quickly spliced ​​by connecting the slots and plugs. This not only ensures the sturdiness between the arc-shaped frames, but also reduces the time spent by workers on splicing the arc-shaped frames. Through the cooperation of the clamping plates, connecting grooves, screw holes and bolts, the connecting grooves can place loads at both ends of the arc-shaped frames. After the bolts are connected to the screw holes, the clamping plates form a closure, which simultaneously provides stable support for the five arc-shaped frames, improving the efficiency of workers on splicing. Traditional trusses are often spliced ​​by multiple bolts, which requires turning multiple bolts during the splicing process, making it cumbersome. Utility Model Content

[0004] To address the shortcomings of existing technologies, traditional trusses are often spliced ​​together using multiple bolts, which involves cumbersome rotation of multiple bolts during the splicing process. This invention proposes a splicing steel structure truss.

The splicing mechanism includes an installation groove, which is formed on the inner wall of the truss body. A limit rod is fixedly connected in the installation groove, and a spring is sleeved on the outer side of the limit rod. An elastic plate is fixedly connected to the inner wall of the truss body, and a pin is slidably connected in the installation groove.

[0006] Preferably, one end of the spring is fixedly connected to the pin, and the other end of the spring is fixedly connected to the mounting groove.

[0007] Preferably, there are four splicing mechanisms, which are arranged in pairs on different truss bodies.

[0008] Preferably, there are four square bars, which are fixed in pairs to different truss bodies. The pin is slidably connected to one of the square bars and to the outside of the limiting bar.

[0009] Preferably, the lower ends of both truss bodies are fixedly connected to a fixing plate, and bolts are movably connected inside the fixing plate. Nuts are fixedly connected to the upper ends of the bolts, and the lower ends of the nuts abut against the upper ends of the fixing plates.

[0010] Preferably, a connecting shaft is mounted on the upper end of the fixing plate via a damping bearing, an mounting plate is fixedly connected to the outer side of the connecting shaft, and a stop plate is fixedly connected to the lower end of the mounting plate, with the lower end of the stop plate abutting against the upper end of the nut.

[0011] Preferably, the abutment is a rubber product, and the lower end of the abutment is serrated.

[0012] The advantages of this utility model are: This invention involves creating a square slot on one side of the truss body and fixing a square rod that fits the slot on the other side. First, the pin is pulled to one side of the elastic plate, and then the elastic plate abuts against the pin. Next, the square rod is inserted into the square slot. At this point, the elastic plate is moved to release the pin's restriction, and the pin is inserted into the square rod under the spring force. This allows the two truss bodies to be spliced ​​together. Compared with the traditional method of rotating bolts, this method can shorten the splicing time and improve work efficiency.

[0017] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail. This application discloses a spliced ​​steel structure truss. (Refer to...) Figure 1 , Figure 2 , Figure 3 and Figure 4 A splicing steel truss includes a truss body 1, the number of truss bodies 1 is two, and a reinforcing steel 2 is fixedly connected to the inner wall of each of the two truss bodies 1. A square groove 3 is opened on one side of each of the two truss bodies 1, and a square bar 4 is fixedly connected to the other side of each of the two truss bodies 1. A splicing mechanism 5 is provided on each of the two truss bodies 1. The splicing mechanism 5 includes a mounting groove 52, which is formed on the inner wall of the truss body 1. A limit rod 53 is fixedly connected in the mounting groove 52, and a spring 54 is sleeved on the outer side of the limit rod 53. An elastic sheet 55 is fixedly connected to the inner wall of the truss body 1. A pin 51 is slidably connected in the mounting groove 52. One end of the spring 54 is fixedly connected to the pin 51, and the other end of the spring 54 is fixedly connected to the mounting groove 52. There are four square rods 4, which are fixed in pairs to different truss bodies 1. The pin 51 is slidably connected to one of the pairs. Inside the square rod 4, the pin 51 is slidably connected to the outside of the limiting rod 53. When splicing the two truss bodies 1, the pin 51 can be pulled first to move to one side of the elastic plate 55. At this time, the pin 51 can be limited by the elastic plate 55. Then, the square rod 4 fixed on one of the truss bodies 1 is inserted into the square groove 3 opened on the other truss body 1. Then, the elastic plate 55 is moved to release the limitation on the pin 51. Under the elastic action of the spring 54, the pin 51 can move and slide out of the square rod 4. At this time, the splicing of the truss body 1 can be completed.

[0018] Reference Figure 1 , Figure 2 , Figure 5 and Figure 6 The lower ends of the two truss bodies 1 are fixedly connected to a fixing plate 6. A bolt 7 is movably connected inside the fixing plate 6. A nut 8 is fixedly connected to the upper end of the bolt 7. The lower end of the nut 8 abuts against the upper end of the fixing plate 6. By rotating the groove on the nut 8, the bolt 7 can be rotated. Then the fixing plate 6 and the truss body 1 can be fixed to the mounting surface by the bolt 7. Reference Figure 1 , Figure 2 , Figure 5 and Figure 6 A connecting shaft 9 is mounted on the upper end of the fixing plate 6 via a damping bearing. A mounting plate 10 is fixedly connected to the outer side of the connecting shaft 9. A stop plate 11 is fixedly connected to the lower end of the mounting plate 10. The lower end of the stop plate 11 abuts against the upper end of the nut 8. The stop plate 11 is made of rubber and has a serrated lower end. After being fixed by bolts 7, the mounting plate 10 can be rotated, and then the lower end of the stop plate 11 abuts against the upper end of the nut 8. The elastic stop plate 11 presses down on the nut 8, and the serrated lower end of the stop plate 11 further increases the friction. Through friction and the damping force provided by the damping bearing, the stability of the stop plate 11 can be improved, preventing the bolts 7 from loosening after long-term use and causing abnormal fixation of the truss body 1.

[0019] Working principle: When splicing two truss bodies 1, the pin 51 can be pulled first to move it to one side of the elastic plate 55. At this time, the pin 51 can be limited by the elastic plate 55. Then, the square rod 4 fixed on one of the truss bodies 1 is inserted into the square groove 3 opened on the other truss body 1. Then, the elastic plate 55 is moved to release the limitation on the pin 51. Under the elastic action of the spring 54, the pin 51 can move and slide out of the square rod 4. At this time, the splicing of the truss body 1 can be completed. Rotating the groove opened on the nut 8 can drive the bolt 7 to rotate. Then, the fixing plate 6 and the truss body 1 can be fixed to the mounting surface by the bolt 7. Rotate the mounting plate 10, and then the lower end of the abutment plate 11 abuts against the upper end of the nut 8. The abutment plate 11 of the elastic product presses down on the nut 8 to prevent the bolt 7 from loosening after long-term use and causing abnormal fixation of the truss body 1.
