Description

Technical Field

[0001] The utility model relates to the technical field of building structures, and more specifically to a building steel structure grid. Background Art

[0002] Building steel structure grid is widely used in modern construction projects, especially in large-span building structures such as large stadiums, exhibition halls, industrial plants, etc. It is mainly composed of a large number of node balls and connecting rods connected to each other. Through reasonable structural design, it can bear various loads of the building and ensure the stability and safety of the building structure.

[0003] In traditional building steel structure grid connection technology, commonly used connection methods include welding and bolt connection.

[0004] The welding connection method requires professional welding workers to operate on the construction site. The process is relatively complicated and time-consuming, and often requires cutting and re-welding of the welding parts, which will not only further damage the integrity of the steel structure, but also increase construction costs and time.

[0005] Although bolted connections are easier to install and disassemble than welding to a certain extent, they also have many problems. During the installation process, bolted connections require the use of a large number of fasteners such as bolts, nuts and washers, which not only increases material costs, but also makes the installation process cumbersome. It takes a lot of time to tighten the bolts to ensure the tightness of the connection.

[0006] In summary, the traditional welding and bolt connection methods have problems such as low connection efficiency and great construction difficulty in the connection of building steel structure grids. For this reason, we propose a building steel structure grid. Utility Model Content

[0028] Furthermore, a locking assembly is provided on the node ball 1 .

[0029] In this embodiment, the locking assembly can be used to complete the locking and fastening operations on several groups of connecting rods 2.

[0030] Furthermore, an adjustment component is also provided on the node ball 1 .

[0031] In this embodiment, the locking assembly can be adjusted and controlled by the adjusting assembly to complete the locking.

[0032] Furthermore, the locking assembly includes a limit plate 7, a clamping plate 9 and a clamping slot 10. The limit plate 7 is arranged inside the adjustment slot 6. Clamping slots 10 are provided at both ends of the connecting rod 2. The clamping slot 10 is an annular groove. The clamping plate 9 is fixedly installed at the bottom of the limit plate 7, and a "U"-shaped groove adapted to the clamping slot 10 is provided at the bottom of the clamping plate 9.

[0033] In this embodiment, after the connecting rod 2 is inserted into the adjustment groove 6 on the node ball 1 through the mounting hole 5, the limit plate 7 is adjusted vertically so that the clamping plate 9 on the limit plate 7 will be snapped into the clamping groove 10 at the corresponding position on the connecting rod 2, thereby completing the snap-in limiting of multiple groups of connecting rods 2.

[0034] Furthermore, the adjustment component includes an adjustment hole 3, an adjustment rod 4, a fixed block 11 and a movable disk 12. The adjustment hole 3 is opened on the node ball 1, and an adjusting rod 4 is arranged inside the adjustment hole 3. The adjusting rod 4 is perpendicular to the connecting rod 2. A thread is arranged on the side wall of the adjusting rod 4, and a thread is arranged on the inner side wall of the adjusting hole 3. The thread on the adjustment hole 3 is adapted to the thread on the adjusting rod 4. A screwing block for conveniently screwing the adjusting rod 4 is arranged on the top of the adjusting rod 4, and a fixed block 11 is arranged at the bottom of the adjusting rod 4. The fixed block 11 is fixedly installed on the top wall of the limit plate 7, and a movable disk 12 is arranged on the side of the fixed block 11 close to the adjusting rod 4. The movable disk 12 is an "I"-shaped annular plate, and the top of the movable disk 12 and the bottom of the adjusting rod 4 are fixedly connected to each other, and an installation groove is opened inside the fixed block 11, and the bottom buckle of the movable disk 12 is installed inside the fixed block 11.

[0035] In this embodiment, by rotating the adjusting rod 4, the adjusting rod 4 is rotated and descended on the adjusting hole 3 through the thread. At the same time, through the fixed block 11 and the movable disk 12 on the fixed block 11, the adjusting rod 4 can drive the movable disk 12 to rotate on the fixed block 11, so that the adjusting rod 4 can drive the fixed block 11 and the limit plate 7 on the fixed block 11 to descend at a vertical angle when rotating, so that the clamping plate 9 on the limit plate 7 can be effectively and stably clamped in the clamping groove 10 on the connecting rod 2. At the same time, through the threaded connection between the adjusting rod 4 and the adjusting hole 3, the tightening effect when the connecting rod 2 is locked can be effectively guaranteed.

[0036] Furthermore, a limiting column 13 is fixedly installed in the middle position of the inner bottom of the adjustment groove 6, and a limiting sleeve rod 8 is fixedly installed in the middle position of the bottom of the limiting plate 7. The bottom of the limiting sleeve rod 8 is hollow, and the size of the hollow area at the bottom of the limiting sleeve rod 8 is adapted to the size of the limiting column 13, and the outer bottom end side wall of the limiting sleeve rod 8 is inclined, and the inclination angle is from top to bottom from the side away from the limiting column 13 to the side close to the limiting column 13.

[0037] In this embodiment, the inclined surface at the bottom of the limit sleeve rod 8 allows the limit plate 7 to effectively adjust the position of the connecting rod 2 inside the adjustment groove 6 by squeezing the inclined surface when it descends, so that the connecting rod 2 can be effectively and accurately buckled through the clamping plate 9 and the clamping groove 10.

[0038] Furthermore, a plurality of groups of limit slots 14 are spaced apart at the top of the limit column 13, and a limit rod 15 is fixedly installed on the inner side of the limit sleeve 8 at a position corresponding to the limit slot 14, and the bottom of the limit rod 15 extends into the limit slot 14, and the limit rod 15 can be raised and lowered in the limit slot 14 by raising and lowering the limit plate 7.

[0041] In this embodiment, when the limit plate 7 is driven to descend by the adjusting rod 4, the limit sleeve rod 8 on the limit plate 7 will squeeze and adjust the connecting rod 2, so that the clamping plate 9 on the limit plate 7 will be snapped into the corresponding position slot 10 on the connecting rod 2, so that the structure can effectively adapt and adjust the installation angle of the connecting rod 2, thereby improving the adaptability of the connected installation of the connecting rod 2.

[0042] The working principle and use process of this utility model:

[0043] During use, when assembling the steel structure grid, several groups of connecting rods 2 are inserted into the adjusting groove 6 on the node ball 1 through the mounting hole 5, and the adjusting rod 4 is screwed so that the adjusting rod 4 is lowered on the adjusting hole 3 through the threaded connection. Under the restriction of the fixed block 11 and the movable disk 12, the limit plate 7 can be effectively driven to descend, so that the clamping plate 9 on the limit plate 7 can be buckled in the clamping groove 10 on the connecting rod 2 at the specified position, thereby completing the buckling of the connecting rod 2. At the same time, when the clamping plate 9 on the limit plate 7 is completely buckled in the clamping groove 10, the adjusting rod 4 is in a tightened state, thereby completing the tightening of the connection installation of the connecting rod 2. Otherwise, the disassembly can be completed effectively and quickly.
