Description

Technical Field

[0001] This utility model relates to the field of building steel structure technology, specifically to a seismic-resistant building steel structure. Background Technology

[0002] Steel structure buildings are a new type of building system. Compared with traditional concrete buildings, steel structure buildings use steel plates or steel sections instead of reinforced concrete. Steel is characterized by high strength, light weight, good overall rigidity, and strong resistance to deformation.

[0003] Patent publication number CN218521942U proposes an earthquake-resistant steel structure for buildings, mainly comprising a beam, a pressure plate, and several sliding rods. The sliding rods are slidably connected to the beam. A third rotating rod moves towards the connecting block, and a second compression spring slowly compresses, thus providing the first buffer for the pressure-bearing part of the main body. A sleeve drives the connecting block to slowly move downward, and the sliding rod slowly moves down along the beam. The first compression spring slowly compresses, thus providing a second buffer during the downward movement of the sliding rod, increasing the shock absorption effect and thereby reducing the vibration of the steel structure. However, for lateral pressure, the above patent often cannot provide effective earthquake resistance in use, reducing the practicality of the device. Utility Model Content

[0004] To address the above problems, the purpose of this utility model is to provide a seismic-resistant steel structure for buildings, which solves the problem that the aforementioned patents often fail to provide effective seismic resistance in use, thus reducing the practicality of the device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a seismic-resistant steel structure, comprising a main steel beam, a damping rod installed on the inner side of the main steel beam, and a limit plate welded to the main steel beam near the damping rod. A helical spring is sleeved on the outer side of the damping rod, a tie rod is installed on the outer side of the main steel beam, and a steel crossbeam is threadedly connected to the lower part of the tie rod. A support rib is inserted into the bottom of the steel crossbeam, a sliding plate is installed at the connection between the steel crossbeam and the main steel beam, and a connecting plate is installed on the side of the sliding plate away from the main steel beam. A connecting pin is installed through the connecting plate.

[0006] The beneficial effects of this utility model are as follows: when the connecting pin is subjected to lateral pressure, it absorbs vibration through deformation. When the connecting pin breaks under force, the sliding plate slides along the limiting plate and the damping rod. The damping rod, together with the helical spring, absorbs the vibration, thereby effectively buffering the device when vibration occurs and increasing the device's shock resistance.

[0007] To cushion the vibration:

[0008] As a further improvement to the above technical solution: the damping rods are symmetrically arranged about the centerline of the main steel beam.

[0009] The beneficial effects of this improvement are: the symmetrically arranged damping rods can work with the sliding plate to absorb the vibrations absorbed by the device, thus buffering the device.

[0010] As a further improvement to the above technical solution: the damping rod and the helical spring are arranged with their axes coincident.

[0011] The beneficial effects of this improvement are: the damping rods with coincident axes, in conjunction with the helical springs, can buffer the steel structure and ensure its seismic resistance.

[0012] To ensure the connection between the limiting plate and the main steel beam:

[0013] As a further improvement to the above technical solution: the cross-section of the limiting plate is L-shaped.

[0014] The beneficial effects of this improvement are: the L-shaped limiting plate can increase the structural strength of the connection point with the main steel beam, ensuring the stability of the limiting plate.

[0015] To limit and guide the sliding plate:

[0016] As a further improvement to the above technical solution: a guide groove is provided on the limiting plate near the sliding plate.

[0017] The beneficial effect of this improvement is that the guide groove can guide and limit the sliding plate during buffering.

[0018] To facilitate the fixing of the connecting plate:

[0019] As a further improvement to the above technical solution: the connecting plate and the main steel beam are connected by welding.

[0020] The beneficial effect of this improvement is that welding can make the connection between the connecting plate and the main steel beam more reliable.

[0021] To facilitate the connection between the connecting pin and the sliding plate:

[0022] As a further improvement to the above technical solution: a blind hole is provided on the sliding plate near the connecting pin, and the cross-section of the sliding plate is C-shaped.

[0023] The beneficial effects of this improvement are: the blind hole allows for easy insertion of the connecting pin into the sliding plate, and the C-shaped design facilitates the connection of the sliding plate with the through damping rod and then with the limiting plate.

[0024] To increase the seismic resistance of the device:

[0025] As a further improvement to the above technical solution: the connecting pins are evenly distributed on the connecting plate.

[0026] The beneficial effect of this improvement is that the equally spaced connecting pins can deform when vibration occurs, thus absorbing the vibration. Attached Figure Description

[0033] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of this utility model in any way.

[0034] like Figure 1-5As shown, a seismic-resistant steel structure includes a main steel beam 1. A damping rod 11 is installed on the inner side of the main steel beam 1, and a limit plate 12 is welded and installed on the main steel beam 1 near the damping rod 11. A helical spring 13 is sleeved on the outer side of the damping rod 11. A tie rod 2 is installed on the outer side of the main steel beam 1, and a steel crossbeam 33 is threadedly connected to the lower part of the tie rod 2. A support rib plate 21 is inserted and installed at the bottom of the steel crossbeam 33. A sliding plate 32 is installed at the connection between the steel crossbeam 33 and the main steel beam 1, and the sliding plate 32 is away from the steel structure. A connecting plate 3 is installed on one side of the main beam 1. A connecting pin 31 is installed through the connecting plate 3. When the connecting pin 31 is subjected to lateral pressure, it absorbs vibration through deformation. When the connecting pin 31 breaks under stress, the sliding plate 32 slides along the limiting plate 12 and the damping rod 11. The damping rod 11, in conjunction with the helical spring 13, absorbs vibration, thereby effectively buffering the device when vibration occurs and increasing the device's seismic performance. The damping rods 11 are symmetrically arranged about the centerline of the steel structure main beam 1. The symmetrically arranged damping rods 11 can work with the sliding plate 32 to absorb the vibration absorbed by the device, thus improving the device's seismic performance. The damping rod 11 and the helical spring 13 are arranged with their axes coincident. The damping rod 11 and the helical spring 13 with their axes coincident can buffer the steel structure and ensure the seismic resistance of the steel structure. The limiting plate 12 has an L-shaped cross-section. The L-shaped limiting plate 12 can increase the structural strength of the connection point with the main beam 1 of the steel structure and ensure the firmness of the limiting plate 12. The limiting plate 12 has a guide groove near the sliding plate 32. The guide groove can guide and limit the sliding plate 32 during buffering. The connecting plate 3 and the steel structure The main beams 1 are connected by welding. Welding makes the connection between the connecting plate 3 and the main beam 1 more reliable. The sliding plate 32 has a blind hole near the connecting pin 31, and the cross-section of the sliding plate 32 is C-shaped. The blind hole allows the connecting pin 31 to be easily inserted into the sliding plate 32. The C-shaped design allows the sliding plate 32 to be easily connected to the limiting plate 12 after passing through the damping rod 11. The connecting pins 31 are evenly distributed on the connecting plate 3. The evenly distributed connecting pins 31 can deform when vibration occurs, absorbing the vibration.

[0035] The working principle of this utility model is as follows: When using this device, the damping rod 11 and the limiting plate 12 are welded to the inner side of the main steel beam 1. The tie rod 2 is installed on the outer side of the main steel beam 1 using bolts. The connecting plate 3 is welded to the outer side of the main steel beam 1. The sliding plate 32 passes through the damping rod 11 and is then welded to the outer side of the connecting plate 3. A connecting pin 31 passes through the connecting plate 3 and the main steel beam 1. The steel beam 33 is then welded onto the sliding plate 32. Bolts are used to connect the tie rod 2 and the steel beam 33. The support rib plate 21 is welded to the connection between the steel structure beam 33 and the main steel structure beam 1 below the beam 33, completing the installation of the device. During use, the tie rod 2, together with the support rib plate 21, provides reliable support for the steel structure beam 33. When lateral pressure occurs, the connecting pin 31 absorbs vibration through deformation when subjected to lateral pressure. When the connecting pin 31 breaks under force, the sliding plate 32 slides along the limiting plate 12 and the damping rod 11. The damping rod 11, together with the helical spring 13, absorbs the vibration, thereby effectively buffering the device when vibration occurs and increasing the device's seismic performance.
