Description

Technical Field

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

[0002] In building steel structures, it is usually necessary to connect the longitudinal circular pipe and the transverse circular pipe to ensure the stability and safety of the overall structure. For example, in the frame structure of a building steel structure, the longitudinal circular pipe and the transverse circular pipe need to be connected to form a stable overall structure.

[0003] Currently, the connection between the longitudinal circular pipe and the transverse circular pipe is usually achieved through bolt connection. Specifically, the two ends of the transverse circular pipe are flat mechanisms and are provided with through holes. A bolt is fixedly connected to the position of the longitudinal circular pipe. When connecting, the through hole at the end of the transverse circular pipe is aligned with the bolt, then the bolt penetrates through the end of the transverse circular pipe, and then the end of the transverse circular pipe is locked by a nut.

[0004] In building steel structures, there may be a situation where the connection angle position between the transverse circular pipe and the longitudinal circular pipe needs to be adjusted circumferentially. For example, during actual construction and installation, due to various factors, the connection position may deviate or need to be adjusted; and the connection method using bolts has the problem of inconvenient disassembly and assembly, resulting in the inability to quickly complete the adaptive adjustment action when the angle position needs to be adjusted, increasing the overall installation difficulty of the circular pipe.

[0011] A second bolt is threadedly installed through the side of the bump away from the arc-shaped plate, and the front end of the second bolt extends into the limiting groove at the corresponding position;

[0031] The positioning component includes a first bolt 5 and two arc-shaped plates 13. Both ends of each arc-shaped plate 13 are fixedly connected with a connecting plate 4. A plurality of mounting holes are formed in the side surface of the connecting plate 4. When fixedly connected to the longitudinal circular tube 1, both arc-shaped plates 13 are clamped on the periphery of the longitudinal circular tube 1. The two connecting plates 4 at the same end on the two arc-shaped plates 13 are arranged in alignment. A first bolt 5 that penetrates the two connecting plates 4 is arranged in the two aligned mounting holes between the two connecting plates 4. Under the locking action of a plurality of first bolts 5, the two arc-shaped plates 13 are fixedly installed on the periphery of the longitudinal circular tube 1; limiting grooves 3 for connecting the mounting component are formed at both the top and bottom ends of the arc-shaped plate 13, and the limiting grooves 3 are coaxial with the arc-shaped plate 13.

[0032] Among them, the mounting component includes a mounting plate 6 arranged on the outer side of the arc-shaped plate 13. The side of the mounting plate 6 close to the arc-shaped plate 13 is in sliding contact with the outer side of the arc-shaped plate 13, and the side of the mounting plate 6 close to the arc-shaped plate 13 is an arc surface that coincides with the radian of the arc-shaped plate 13;

[0033] On the side of the mounting plate 6 close to the arc-shaped plate 13, bumps 7 are fixedly connected at both end positions. The two bumps 7 are respectively in sliding contact with the top and bottom surfaces of the arc-shaped plate 13;

[0034] A second bolt 8 is threadedly installed through the side of the bump 7 away from the arc-shaped plate 13, and the front end of the second bolt 8 extends into the limiting groove 3 at the corresponding position;

[0035] When it is necessary to limit the position between the mounting plate 6 and the arc-shaped plate 13, the front end of the second bolt 8 is in pressing contact with the inner end of the limiting groove 3;

[0036] On the side of the mounting plate 6 away from the arc-shaped plate 13, a limiting component for connecting the end of the transverse circular tube 2 is fixedly installed.

[0037] Among them, the limiting component includes a fixed clamping plate 14 fixedly installed at the bottom end position on the side surface of the mounting plate 6 and a fixed seat 9 fixedly installed at the top end position on the side surface of the mounting plate 6;

[0038] A threaded rod 11 is threadedly installed through the top surface of the fixed seat 9. A knob 10 is fixedly installed at the top end of the threaded rod 11. The bottom end of the threaded rod 11 is rotatably connected with a movable clamping plate 12 located directly above the fixed clamping plate 14, and the end of the movable clamping plate 12 close to the mounting plate 6 is in sliding contact with the mounting plate 6.

[0039] Among them, both the movable clamping plate 12 and the fixed clamping plate 14 are arc-shaped structures, and rubber layers are arranged on the inner arc surfaces of both the movable clamping plate 12 and the fixed clamping plate 14.

[0040] When the utility model is in use:

[0041] In the positioning component, two arc-shaped plates 13 are aligned and clamped at a preset position on the periphery of the longitudinal circular tube 1. Then, the two arc-shaped plates 13 are fixed to the periphery of the longitudinal circular tube 1 by the first bolt 5. When connecting the transverse circular tube 2, the end of the transverse circular tube 2 is placed between the movable clamping plate 12 and the fixed clamping plate 14. Then, the threaded rod 11 is rotated by the knob 10, so that the threaded rod 11 drives the movable clamping plate 12 to descend until the transverse circular tube 2 is clamped and fixed between the movable clamping plate 12 and the fixed clamping plate 14. In the positioning component, through the cooperative setting of the arc-shaped plate 13, the connecting plate 4 and the first bolt 5, the fixed position of the positioning component on the periphery of the longitudinal circular tube 1 is adjustable, which improves the flexibility of the connection operation between the longitudinal circular tube 1 and the transverse circular tube 2.

[0042] During the process, when it is necessary to adjust the circumferential angle of the connection of the transverse circular tube 2, the mounting plate 6 is slid on the periphery of the arc-shaped plate 13, so as to achieve the purpose of circumferential angle adjustment. After the adjustment is completed, by rotating the second bolt 8, the front end of the second bolt 8 is in pressing contact with the inner end of the limiting groove 3, so that the positional state between the mounting plate 6 and the arc-shaped plate 13 is fixed. Therefore, in the mounting component of the present utility model, through the cooperative setting of the mounting plate 6, the convex block 7, and the second bolt 8 and the limiting groove 3 at the top and bottom ends of the arc-shaped plate 13, the mounting component can be adjusted by a certain range of angles in the circumferential direction of the longitudinal circular tube 1, so as to facilitate quick adjustment when there is a deviation in the connection position 2 at both ends of the transverse circular tube 2, which provides convenience for the installation work of the longitudinal circular tube 1 and the transverse circular tube 2 and improves the practicability of the present utility model. And through this setting, multiple groups of mounting components can be installed on the positioning component, so that multiple transverse circular tubes 2 can be connected at this position. The specific quantity can be determined according to actual needs, which further improves the practicability of the present utility model.

[0043] In the limiting component, the rotation of the threaded rod 11 controlled by the knob 10 can drive the movable clamping plate 12 to rise and fall, so as to cooperate with the fixed clamping plate 14 to clamp and loosen the end of the transverse circular tube 2, realizing the quick disassembly and assembly function between the longitudinal circular tube 1 and the transverse circular tube 2, thereby improving the disassembly and assembly efficiency between the longitudinal circular tube 1 and the transverse circular tube 2.
