Description

Technical Field

[0001] The utility model relates to the technical field of grid web bars, in particular to a roof grid web bar structure. Background Art

[0002] Many building structures use grid structures as roof structures. Grid structures have the advantages of convenient and quick processing and construction. Grid structures mainly include upper chords, lower chords and webs connected between the upper and lower chords. The webs and the upper and lower chords are usually connected by bolt balls.

[0003] In the prior art, a bolt ball is usually arranged between the web and the upper and lower chords, and a bolt is rotatably arranged on the web. The bolt is inserted into the bolt hole on the bolt ball and tightened by rotating the bolt, so that the two ends of the web are respectively connected to the two bolt balls, and the web is connected and installed between the upper and lower chords.

[0004] During actual use, the belly bar may produce certain wear or damage and need to be disassembled for replacement and repair. However, the bolts at both ends of the belly bar are inserted into the bolt holes. At the same time, in order to ensure the stability of the connection, there is basically no relative displacement between the bolts and the belly bar body. Therefore, there is not much space for the bolts to exit the bolt holes, which makes disassembly very inconvenient. Utility Model Content

[0005] In order to improve the convenience of disassembly, the present application provides a roof grid web structure.

[0006] The present application provides a roof grid web structure that adopts the following technical solution:

[0007] A roof truss web structure includes a connecting rod, a bolt ball and a connecting bolt arranged on the connecting rod, wherein the surface of the bolt ball is provided with a bolt hole, the connecting bolt is inserted into the bolt hole and threadedly connected with the bolt hole, the connecting rod includes a first assembly rod and a second assembly rod, the connecting bolt is arranged on the first assembly rod and the second assembly rod, the first assembly rod is provided with a first assembly groove, the second assembly rod is slidably arranged in the first assembly groove, the second assembly rod can rotate in the first assembly groove, a fixing component is arranged between the first assembly rod and the second assembly rod, and the fixing component is used to fix the first assembly rod and the second assembly rod.

[0008] By adopting the above technical solution, when installing the belly rod, first, the connecting bolt on the first assembly rod is adapted to be inserted into the bolt hole on a bolt ball and tightened, and then the second assembly rod is pulled to drive the second assembly rod to slide in the first assembly groove until the connecting bolt on the second assembly rod is inserted into the bolt hole on the other bolt ball, and then the second assembly rod is turned to make the connecting bolt threadedly connected to the bolt hole, and then the first assembly rod and the second assembly rod are fixed together by the fixing component, thereby completing the installation of the belly rod. When the installed belly rod is damaged and needs to be disassembled, the fixing between the first assembly rod and the second assembly rod is first released by the fixing component, and the second assembly rod is rotated to drive the connecting bolt on the second assembly rod to rotate, so that the connecting bolt is withdrawn from the bolt hole on the bolt ball. In this process, the second assembly rod slides in the first assembly groove, and then the first assembly rod is rotated to drive the connecting bolt on the first assembly rod to rotate, so that the connecting bolt on the first assembly rod is withdrawn from the bolt hole into which it is inserted, and the disassembly of the belly rod can be completed. The operation is simple and convenient, which improves the convenience of disassembly of the belly rod.

[0009] Preferably, the fixing assembly includes a fixing thread block and a fixing bolt, the fixing bolt is used to fix the first assembly rod and the second assembly rod, the inner wall of the first assembly groove is provided with a second assembly groove, the fixing thread block is arranged on the second assembly rod and inserted into the second assembly groove, the inner wall of the first assembly groove is provided with a thread groove communicating with the second assembly groove, and the fixing thread block can be inserted into the thread groove and threadedly connected with the thread groove.

[0010] By adopting the above technical scheme, when the second assembly rod slides in the first assembly groove so that the connecting bolt on the Durr assembly rod is inserted into the bolt hole, the second assembly rod is disengaged from the second assembly groove, and the fixed thread block is disengaged from the second assembly groove and inserted into the thread groove. At the same time, when the second assembly rod is turned to make the connecting bolt threadedly connected to the bolt hole, the fixed thread block is synchronously threadedly connected with the thread groove, and the fixation of the first assembly rod and the second assembly rod is preliminarily completed. Thereafter, the first assembly rod and the second assembly rod are fixed together by the fixing bolt, thereby increasing the stability of the fixation between the first assembly rod and the second assembly rod. When the web rod needs to be disassembled, the fixing bolt is first removed, and the second assembly rod is rotated at the same time, so that the connecting bolt on the second assembly rod is withdrawn from the bolt hole on the bolt ball, and the fixed thread block is withdrawn from the thread groove and inserted into the second assembly groove. At this time, the second assembly rod is also partially inserted into the second assembly groove, thereby synchronously releasing the fixation between the first assembly rod and the second assembly rod during the disassembly process, further improving the convenience of disassembly of the web rod.

[0011] Preferably, a locking block is provided on the second assembly rod, the locking block is arranged in the second assembly groove, the locking block is provided with a locking assembly, and the locking assembly is used to lock the second assembly rod.

[0012] By adopting the above technical solution, when the belly rod is not installed, the second assembly rod is locked by the locking assembly so that the second assembly rod remains inserted into the second assembly groove, thereby reducing the possibility of the second assembly rod sliding freely in the first assembly groove, thereby reducing the interference of the second assembly rod with the installation of the connecting bolts on the first assembly rod, and improving the convenience of belly rod installation.

[0013] Preferably, the locking assembly includes a locking rod and a locking spring, a locking groove is provided on the locking block, the locking rod is slidably arranged in the locking groove, the locking spring is arranged in the locking groove, the locking spring connects the inner wall of the locking groove and the locking rod, the locking rod is abutted against the inner wall of the second assembly groove, the first assembly rod is provided with a first locking hole communicated with the second assembly groove, and the locking rod can pass through the first locking hole.

[0014] By adopting the above technical solution, when the belly rod is not installed, the second assembly rod is pushed to slide in the second assembly groove and the first assembly groove. During this process, the locking rod continues to abut against the inner wall of the second assembly groove and compress the locking spring until the locking rod moves to the first locking hole. At this time, the locking spring recovers and pushes the locking rod through the first locking hole, thereby locking the second assembly rod and reducing the space occupied by the second assembly rod, thereby facilitating the storage and accommodation of the belly rod. At the same time, the second assembly rod is locked and cannot slide, thereby facilitating the installation of the connecting bolts on the first assembly rod. When the lock needs to be released, the locking rod is pressed to make the locking rod disengage from the first locking hole and compress the locking spring. At this time, the second assembly rod can be pulled to drive the locking block to move, so that the locking rod moves together and abuts against the inner wall of the second assembly groove, thereby releasing the lock. The overall operation is very simple.

[0015] Preferably, an inner wall of the first locking hole is provided with an inclined surface.

[0016] By adopting the above technical solution, the inclined surface facilitates the locking rod to be inserted into the first locking hole, thereby improving the convenience of use.

[0017] Preferably, the locking block is rotatably connected to the second assembly rod, the inner wall of the second assembly groove is provided with a sliding groove communicated with the first locking hole, and the locking rod is inserted into the sliding groove and abuts against the inner wall of the sliding groove.

[0018] By adopting the above technical solution, the locking block is rotatably connected to the second assembly rod so that the locking block does not rotate with the second assembly rod when the second assembly rod rotates. The sliding groove limits the movement of the locking rod to a certain extent. At the same time, the sliding groove shortens the length of the first locking hole, making it convenient to press the locking rod to release the lock, thereby improving the convenience of use. At the same time, by setting the sliding groove, a part of the compressed elastic potential energy of the locking spring can be released, thereby reducing the probability of damage to the locking spring and improving durability.

[0019] Preferably, the locking block can abut against the inner wall of the second assembly groove, the first assembly rod is provided with a second locking hole communicated with the sliding groove, and the locking rod can pass through the second locking hole.

[0020] By adopting the above technical solution, when the second assembly rod is extended for installation, the locking block abuts against the inner wall of the second assembly groove, reducing the possibility of the second assembly rod completely disengaging from the first assembly groove, thereby facilitating use. At the same time, the locking spring restores and pushes the locking rod through the second locking hole, thereby locking the first assembly rod and the second assembly rod. The locking of the locking rod shares the pressure on the fixed component, reducing the possibility of separation of the first assembly rod and the second assembly rod after the belly rod is installed, thereby improving the durability of the belly rod after installation.

[0021] Preferably, both the first assembly rod and the second assembly rod are provided with an insert block, and the bolt ball is provided with a slot into which the insert block can be inserted.

[0022] By adopting the above technical solution, when the connecting bolt is inserted into the bolt hole on the bolt ball, the insert block is inserted into the slot to share part of the pressure on the connecting bolt, thereby reducing the possibility of damage to the connecting bolt and improving the durability of the connecting bolt.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. By setting a connecting rod, a first assembly rod, a second assembly rod, a first assembly groove, a fixing assembly, a connecting bolt, a bolt ball and a bolt hole, the web rod is installed after the bolt balls at both ends are fixed, first the connecting bolt on the first assembly rod is inserted into the bolt hole and tightened, then the second assembly rod is pulled to slide in the first assembly groove until the connecting bolt on the second assembly rod is inserted into the bolt hole on the other bolt ball, the second assembly rod is rotated to make the connecting bolt and the bolt hole threadedly connected, and then the second assembly rod and the second assembly rod are fixed by the fixing assembly, so as to improve the stability of the connection between the two, and the fixing assembly is used to release the fixation during disassembly, and then the second assembly rod is rotated to make the connecting bolt on the second assembly rod withdraw from the bolt hole, at this time the second assembly rod slides in the first assembly groove, and there is enough withdrawal space for operation, and then the first assembly rod is rotated to make the connecting bolt on the first assembly rod withdraw from the bolt hole, thereby improving the convenience of disassembly of the web rod;

[0025] 2. After the connecting bolt on the first assembly rod is installed by setting the second assembly groove, the thread groove, the fixed thread block and the fixing bolt, the second assembly rod is pulled to slide so that the second assembly rod is disengaged from the second assembly groove, and the fixed thread block is disengaged from the second assembly groove and inserted into the thread groove. At this time, the connecting bolt on the second assembly rod is inserted into the bolt hole on the bolt ball, and the second assembly rod is rotated so that the connecting bolt is threadedly connected to the bolt hole, and the fixed thread block is threadedly connected to the thread groove. Then, the first assembly rod and the second assembly rod are further fixed by the fixing bolt, which simplifies the fixing steps and further improves the convenience of disassembly.

[0026] 3. By setting the first locking hole, the locking rod, the locking spring, the locking block and the locking groove, when the second assembly rod is extended, the locking rod abuts against the inner wall of the second assembly groove and compresses the locking spring. When not installing, the second assembly rod can be retracted to slide in the second assembly groove until the locking rod faces the first locking hole. At this time, the locking spring restores and pushes the locking rod through the first locking hole, and abuts against the locking rod through the inner wall of the first locking hole, thereby locking the second assembly rod, reducing the space occupied by the second assembly rod for easy storage, and locking the second assembly rod reduces the influence of the movement of the second assembly rod on the installation of the connecting bolt on the first assembly rod, thereby facilitating installation.

[0034] Reference Figure 1 and Figure 2 During installation, the two bolt balls 2 can be fixed first, the connecting bolt 3 on the first assembly rod 11 can be inserted into the bolt hole 21 on one end of the bolt ball 2 and tightened, then the second assembly rod 12 can be slid so that the connecting bolt 3 on the second assembly rod 12 can be inserted into the bolt hole 21 on the other bolt ball 2, the second assembly rod 12 can be rotated to tighten the connecting bolt 3, and then the first assembly rod 11 and the second assembly rod 12 can be fixed by the fixing assembly 4. When disassembly is required, the fixing assembly 4 can be released first, and then the second assembly rod 12 can be rotated so that the connecting bolt 3 on the second assembly rod 12 can be withdrawn from the bolt hole 21. During this process, the second assembly rod 12 slides in the first assembly groove 111, and then the first assembly rod 11 can be rotated so that the connecting bolt 3 on the first assembly rod 11 can be withdrawn from the bolt hole 21 to complete the disassembly, thereby improving the convenience of disassembly of the web rod.

[0035] To improve the stability of the fixation, refer to Figure 1 and Figure 2The fixing assembly 4 includes a fixing thread block 41 and a fixing bolt 42. The fixing bolt 42 is used to fix the first assembly rod 11 and the second assembly rod 12 from the side. The inner wall of the first assembly groove 111 is provided with a circular second assembly groove 112, and the inner wall of the first assembly groove 111 is also provided with a circular thread groove 113 that communicates with the second assembly groove 112. The diameter of the circular thread groove 113 is smaller than the diameter of the second assembly groove 112. The fixing thread block 41 is cylindrical and fixedly arranged at one end of the second assembly rod 12 close to the first assembly rod 11. The fixing thread block 41 is inserted into the second assembly groove 112 and can be inserted into the thread groove 113 and threadedly connected with the thread groove 113. When the second assembly rod 12 is slid for installation, when the connecting bolt 3 on the second assembly rod 12 is inserted into the bolt hole 21, the fixing thread block 41 is inserted into the thread groove 113. At this time, the second assembly rod 12 can be rotated to tighten the connecting bolt 3 and the fixing thread block 41 at the same time, and then the first assembly rod 11 and the second assembly rod 12 are fixed laterally by the fixing bolt 42. The fixing screw block 41 is fixed in cooperation with the fixing bolt 42, thereby improving the stability of the fixing.

[0036] To improve the convenience of use, refer to Figures 2 to 4 The fixed thread block 41 is provided with a cylindrical locking block 5 at one end away from the second assembly rod 12 through a rotating shaft.

[0037] Reference Figures 2 to 4When the second assembly rod 12 is slid, the locking block 5 slides in the second assembly groove 112, and the locking rod 61 slides in the sliding groove 114. When the second assembly rod 12 is stretched so that the connecting bolt 3 is inserted into the bolt hole 21, the locking block 5 abuts against the inner wall of the second assembly groove 112 near the end of the thread groove 113. At this time, the locking rod 61 is aligned with the second locking hole 64, and the locking spring 62 is restored to push the locking rod 61 through the second locking hole 64. The second assembly rod 12 is locked by the locking rod 61 abutting against the inner wall of the second locking hole 64. When installing one end of the first assembly rod 11, the second assembly rod 12 can be slid and retracted to make the locking block 5 slide in the second assembly groove 112 until the locking rod 61 is aligned with the first locking hole 63. At this time, the locking spring 62 is restored to push the locking rod 61 through the first locking hole 63 to lock the second assembly rod 12, reducing the impact of the sliding of the second assembly rod 12 on the installation of the connecting bolt 3 on one side of the first assembly rod 11, thereby improving the convenience of use.
