Description

Technical Field

[0001] This utility model relates to the field of metal steel space frame technology, and in particular to an earthquake-resistant metal steel space frame structure. Background Technology

[0002] In modern construction engineering, metal steel space frame structures are widely used due to their advantages such as light weight, large span, and high space utilization. A typical steel space frame structure is usually composed of basic components such as main trusses, upper and lower chords, and web members connected by nodes to form a stable spatial force-bearing system. With the increasing safety requirements for buildings in earthquake-prone areas, the seismic performance of steel space frame structures has become a key indicator in engineering design.

[0003] A search revealed Chinese patent CN222632906U, which provides a seismic reinforcement device for steel structure space frame. The device utilizes a threaded column, a first nut, a second nut, and a first spring to buffer the seismic activity of the space frame, increasing stability and safety. A piston rod, cylinder, partition, hydraulic oil, and flow pipe further enhance the damping effect. A ring and a second spring also contribute to damping. Multiple damping structures work together to absorb the kinetic energy generated by vibration, resulting in excellent stability and safety.

Bolts 310 are screwed onto both sides of the second connector 305, and the threads of the two bolts 310 rotate in opposite directions. Rotating the second connector 305 can adjust the connection force, making it easy to adjust to a suitable anti-vibration effect. The second damping holes 309 further reduce the impact of vibration energy.

[0037] The outer end of the bolt 310 is rotatably connected to a hinge 311, one of which is fixedly connected to the outer peripheral wall of the collar 301, and the other hinge 311 is fixedly connected to a second anchor 312; the second connector 305 is installed with the bolts 310 at both ends by rotating the second connector 305, and the connection force is adjusted by rotating the second connector 305.

A support 404 is fixedly provided on the outer peripheral wall of the jacket 401, and an adjusting block 405 is provided at the outer end of the support 404. Multiple slots 406 are provided on the adjusting block 405, and multiple positioning holes 407 are provided on the outer wall of the adjusting block 405. Two L-shaped blocks 408 are respectively snapped onto both ends of the adjusting block 405. One L-shaped block 408 is connected and fixed to the fixing block 413 by bolts, and the other L-shaped block 408 is screwed to the third anchor 409 by bolts. The fixing block 413 is installed and fixed through the through hole 403, so that the slot 406 on the jacket 401 is snapped into the anti-slip sleeve 103.

The two L-shaped blocks 408 are adjusted to rotate to a suitable angle.

[0042] A T-shaped rod 410 is inserted into the L-shaped block 408. The T-shaped rod 410 is inserted into the positioning hole 407. A spring 411 is fixed on the T-shaped rod 410. A support member 412 is fixed on the outer wall of the L-shaped block 408. The inner wall of the support member 412 is fixedly connected to the outer end of the spring 411. When the T-shaped rod 410 is released, the restoring force of the spring 411 causes the T-shaped rod 410 to be inserted into the positioning hole 407, thus completing the installation of the second anti-seismic component 400.

[0043] In use, the sleeve 401 is installed on the anti-slip sleeve 103 in a suitable position and fixed through the through hole 403 on the fixing block 413, so that the slot 406 on the sleeve 401 engages with the anti-slip sleeve 103. After the third anchor 409 is installed in a suitable position, the two L-shaped blocks 408 are installed on the support 404 and the third anchor 409 respectively. After adjusting the two L-shaped blocks 408 to a suitable angle, the two T-shaped inserts 410 are pushed to separate from the L-shaped blocks 408, so that the spring 411 is compressed. Then, the adjusting block 405 is engaged with the L-shaped block 408 through the slot 406. The T-shaped inserts 410 are released and, through the restoring force of the spring 411, the T-shaped inserts 410 are engaged with the positioning hole 407, thus completing the installation of the second seismic component 400. This further improves the seismic resistance of the main truss 101 and reduces the impact of horizontal vibration on the steel grid body 100.
