Description

Technical Field

[0001] The utility model relates to the technical field of steel structures, in particular to an earthquake-resistant steel structure. Background Art

[0002] Earthquake-resistant steel structure refers to a building structure constructed with steel components. Its design, construction and material selection are all aimed at improving the earthquake resistance of the structure.

[0003] Earthquake-resistant steel structures are constructed through reasonable design, selection of high-strength steel and adoption of advanced construction technology. They can maintain structural stability and reduce damage under earthquakes. Currently, in steel structure buildings, I-steel sections are reinforced by welding, resulting in greater rigidity at the connection points. When the force at the connection points reaches the yield point, they cannot continue to bear the load under large deformation, resulting in fracture and reducing overall stability.

[0004] In response to the above problems, this utility model document proposes an earthquake-resistant steel structure. Utility Model Content

[0005] The utility model provides an earthquake-resistant steel structure, which solves the problem in the prior art that the I-steel sections are reinforced by welding, resulting in a large rigidity at the connection points. After the force at the connection points reaches the yield point, they cannot continue to bear the load under large deformation, resulting in fracture, which reduces the overall stability.

[0006] The utility model provides the following technical solutions:

[0007] An earthquake-resistant steel structure, comprising:

[0008] Vertical I-shaped steel, with horizontal I-shaped steel arranged on both sides of the vertical I-shaped steel;

[0009] Ductile connectors are installed on vertical I-shaped steel sections to improve the plasticity of the connection between them and horizontal I-shaped steel sections to prevent sudden fracture due to vibration;

[0010] The buffer reinforcement is installed on the horizontal I-shaped steel to strengthen its connection with the vertical I-shaped steel and provide a certain swing amplitude for the horizontal I-shaped steel.

[0011] In one possible design, the ductile connector includes a T-shaped connecting plate provided on both sides of the vertical I-shaped steel, wherein the protruding plate of the T-shaped connecting plate extends to the inner wall of the horizontal I-shaped steel and is fixed by a plurality of second bolts.

[0012] In a possible design, the bottom plate of the T-shaped connecting plate is fixed to the vertical I-shaped steel by a plurality of first bolts.

[0013] In a possible design, the buffer reinforcement includes two dampers hinged to the top and bottom of the transverse I-shaped steel through hinged seats, and the other ends of the dampers are hinged to the vertical I-shaped steel through corresponding hinged seats.

[0014] In a possible design, the plurality of hinged seats are mounted on the vertical I-shaped steel and the horizontal I-shaped steel via two corresponding third bolts.

[0015] In a possible design, washers for rust prevention are provided on the nuts of the bolts.

[0016] It should be understood that the above general description and the following detailed description are merely illustrative and do not limit the present invention.

[0017] The working principle and usage process of this technical solution are as follows:

[0018] During installation, the vertical I-shaped steel is positioned and fixed according to the design drawings to ensure that it is vertical and stable. On both sides of the vertical I-shaped steel, multiple first bolts are used to firmly fix the bottom plate of the T-shaped connecting plate to the vertical I-shaped steel to ensure that the position of the T-shaped connecting plate is accurate and corresponds to the installation position of the horizontal I-shaped steel. Afterwards, the horizontal I-shaped steel is placed on the convex plate extension of the T-shaped connecting plate, and multiple second bolts are used to fix the convex plate of the T-shaped connecting plate to the inner wall of the horizontal I-shaped steel. In this way, the ductile connection between the vertical I-shaped steel and the horizontal I-shaped steel is completed. Then, the damper is installed at the top and bottom of the horizontal I-shaped steel through the hinge seat, and the other end of the damper is hinged to the vertical I-shaped steel through the corresponding hinge seat. The hinge seat is firmly installed on the vertical I-shaped steel and the horizontal I-shaped steel with a third bolt. After all installations are completed, the overall structure is comprehensively inspected to ensure that all components are installed correctly and there is no looseness. Adjustments are made as needed to ensure the stability and seismic performance of the seismic steel structure.

[0019] The utility model has the following beneficial effects:

[0020] Through the design of ductile connectors and buffer reinforcements, the utility model enables the seismic steel structure to better absorb and disperse energy under external forces such as earthquakes, thereby reducing the probability of fracture at the connection and improving the overall seismic performance.

[0021] The use of ductile connectors in the present invention enhances the connection strength between the vertical I-shaped steel and the horizontal I-shaped steel, making the overall structure more stable. At the same time, the provision of the damper further strengthens the structure and allows the horizontal I-shaped steel to swing within a certain range to consume seismic energy.

[0022] The utility model constructs a steel structure system with stable structure and excellent seismic performance. The system effectively improves the survivability and safety of the steel structure in natural disasters such as earthquakes through reasonable design of ductile connectors and buffer reinforcements.

[0028] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] In the description of the present invention, it should be understood that the terms "opening", "upper", "middle", "length", "inner" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0030] In order to keep the following description of the embodiments of the present invention clear and concise, the present invention omits detailed descriptions of known functions and known components.

[0031] Example 1

[0032] Please refer to Figure 1-4 , an earthquake-resistant steel structure, which is used in the field of steel structure, including:

[0033] The vertical I-shaped steel 1 serves as the main supporting component of the seismic-resistant steel structure. Two horizontal I-shaped steels 2 are installed in parallel on both sides of the vertical I-shaped steel 1 to form a basic frame structure. The two horizontal I-shaped steels 2 intersect the vertical I-shaped steel 1 at right angles to each other, forming a stable support system.

[0034] In order to improve the plasticity and seismic resistance of the connection between the vertical I-shaped steel 1 and the horizontal I-shaped steel 2, a T-shaped connecting plate 3 is installed on each side of the vertical I-shaped steel 1. The bottom plate part of the T-shaped connecting plate 3 is tightly fixed to the side of the vertical I-shaped steel 1 by multiple first bolts 4 to ensure a stable connection. The convex plate part of the T-shaped connecting plate 3 extends to the inner wall of the horizontal I-shaped steel 2 and is further fixed by multiple second bolts 5. In this way, a connection structure that is both firm and has a certain ductility is formed between the vertical and horizontal I-shaped steels 2, which helps to absorb energy under the action of external forces such as earthquakes and prevent sudden fracture.

[0035] In order to further enhance the stability of the transverse I-shaped steel 2 and give it a certain swing amplitude to cope with seismic fluctuations, a damper 6 is installed at the top and bottom of the transverse I-shaped steel 2. One end of the damper 6 is hinged to the transverse I-shaped steel 2 through a hinge seat 7, and the other end is hinged to the vertical I-shaped steel 1 through another hinge seat 7. This design enables the transverse I-shaped steel 2 to swing within a certain range when subjected to external forces such as earthquakes, thereby consuming seismic energy and improving the seismic resistance of the overall structure. When installing the hinge seat 7, a third bolt 8 is used to firmly fix it to the corresponding positions of the vertical I-shaped steel 1 and the transverse I-shaped steel 2.

[0036] Example 2

[0037] Improvements based on Example 1:

[0038] Please refer to Figure 3 In order to ensure the reliability and durability of the connection, an anti-rust washer is installed on the nut of each bolt to prevent the bolt from rusting due to long-term exposure to humid or corrosive environments, which will affect the connection strength.
