Description

Technical Field

[0001] This utility model belongs to the technical field of sliding supports for steel components, specifically a temperature stress relief structure for ultra-long steel structure buildings. Background Technology

[0002] With the deepening of China's energy transition, electricity demand is showing a rapid growth trend. The development of the power industry is not only related to energy supply security, but also a key factor in promoting high-quality economic development. According to power grid and urban development plans, in order to meet the power supply needs of urban economic construction, 500kV substations for all households in cities have become a development trend.

[0003] Due to the manufacturing requirements of electrical equipment, the steel structure of the 500kV substation, an indoor building in the city, is over 90 meters long. Temperature deformation and stress are significant factors; improper handling in the structural design can lead to cracks and damage, severely impacting the building's usability. To effectively mitigate the adverse effects of temperature stress, the conventional practice is to reserve temperature-resistant structural joints at appropriate locations within the building, such as... Figure 1 As shown, the building is completely disconnected from the roof, walls, floors and other above-ground components, and double columns are set on both sides of the gap. This increases the amount of construction work and the amount of steel used will also increase exponentially, resulting in a corresponding increase in cost.

[0004] For example, Chinese invention patent CN114232798B, with an authorization announcement date of April 28, 2023, discloses an ultra-long steel structure system resistant to temperature deformation, including two side columns and a central column. The central column is connected to the two side columns by a crossbeam. The two sides of the central column are respectively provided with load-bearing members for supporting the crossbeams on the same side. Each crossbeam has a connecting rod hinged to one end near the central column. The two connecting rods are hinged and intersecting each other. The top of the central column is provided with two limiting plates corresponding to the two connecting rods. Each connecting rod has a limiting shaft at the end away from the connected crossbeam. Each limiting plate has a limiting groove. Each limiting shaft is slidably embedded in the limiting groove corresponding to its corresponding connecting rod.

[0005] The aforementioned prior art can cope with temperature stress, but it has the following problems:

[0006] 1. The structure for resisting temperature deformation is very complex and cumbersome, and the production cost is very high;

[0007] 2. The large number of parts makes later maintenance inconvenient;

[0008] 3. It requires a high level of knowledge from construction workers, and the installation is relatively complex and difficult.

[0009] Therefore, how to effectively solve the above problems is an urgent technical issue that needs to be addressed.

[0010] It should be noted that the above technical information is intended only to enhance the understanding of the overall background technology of this utility model, and should not be regarded as an admission or in any form implying that the above technical information constitutes prior art known to those skilled in the art. Utility Model Content

[0011] To address the shortcomings of the aforementioned background technology, this utility model proposes a temperature stress relief structure for ultra-long steel structure buildings, which solves the problems of complex and costly anti-temperature deformation structures, large construction volume, relatively complex and difficult installation, and numerous parts that cause inconvenience for later maintenance.

[0012] The technical solution of this application is as follows:

[0013] A temperature stress relief structure for ultra-long steel structure buildings, comprising a frame structure formed by columns and beams, is disclosed. The structure includes a sliding support assembly positioned between the columns and beams along the length of the frame structure. One end of each beam slides into the sliding support assembly, and the other end is connected to an adjacent steel column. The sliding support assembly includes a cylinder that slides into the beam. Materials expand and contract with temperature changes. At high temperatures, the material expands, exhibiting tensile force, thus reducing the distance between the beam and adjacent steel columns for temperature stress relief. At low temperatures, the material contracts, exhibiting contractile force, thus increasing the distance between the beam and adjacent steel columns for temperature stress relief. Due to the ultra-long length of the building structure, the internal temperature stress of the material is significant. This invention directly releases the temperature stress through the sliding support assembly, resulting in significant effectiveness and greater convenience, requiring no additional operation.

[0014] Furthermore, the length of the beam is less than the distance between the opposite faces of adjacent steel columns.

[0015] Furthermore, the steel column is connected to a corbel on its side, and the sliding support assembly is disposed between the corbel and the beam.

[0016] Furthermore, the sliding support assembly includes several baffles disposed on the upper surface of the bracket, and the cylinder is disposed within the cavity formed by the several baffles, the axis of the cylinder being parallel to the width direction of the beam.

[0017] Furthermore, to ensure that the sliding support has good sliding ability, at least two cylinders are provided.

[0018] Furthermore, a pad is provided between the baffle and the upper surface of the corbel. The corbel needs to bear a large load pressure at the support node. The pad can effectively disperse the pressure on the structure, reduce the impact and damage caused by the pressure, and thus improve safety.

[0019] Furthermore, to enhance the strength and rigidity of the connection parts of the sliding support assembly and prevent the sliding performance of the support assembly from being affected by deformation under load, a number of stiffening ribs are provided between the baffle and the pad.

[0020] Furthermore, a second pad and a third pad are sequentially arranged between the cylinder and the beam, and a fourth pad is arranged between the cylinder and the first pad.

[0021] Furthermore, a polytetrafluoroethylene (PTFE) plate is provided between the pad three and the baffles disposed on both ends of the cylinder, and the two sides of the PTFE plate are respectively attached to the pad three and the baffles.

[0022] Furthermore, a gap is provided between the pad four and the steel column, which facilitates construction.

[0023] The specific beneficial effects of this utility model include:

[0024] 1. The sliding support assembly in this utility model allows the deformation of the beam caused by temperature changes to be released freely without generating internal forces, thus eliminating the adverse effects of temperature on safety and aesthetics.

[0025] 2. Materials undergo thermal expansion and contraction when the temperature changes. At high temperatures, the material expands, resulting in tensile force, which reduces the distance between the beam used for temperature stress release and the adjacent steel column. At low temperatures, the material contracts, resulting in contractile force, which increases the distance between the beam used for temperature stress release and the adjacent steel column. Due to the extremely long building structure, the internal temperature stress of the material is significant. This utility model directly releases the temperature stress through the sliding support assembly, which is effective, convenient, and requires no additional operation.

[0026] 3. The node layout is flexible and the construction speed is fast. Compared with the conventional solution, it can save 40t of steel, resulting in significant economic benefits.

[0027] 4. During an earthquake, the structure will be subjected to horizontal seismic forces. The sliding support assembly can allow the structure to slide in the horizontal direction, thereby consuming seismic energy, reducing the seismic response of the structure, and reducing the damage caused by the earthquake to the structure.

The sliding support assembly 1 includes a cylinder 6 that slidably engages with the beam 3. Materials expand and contract with temperature changes. At high temperatures, the material expands, exhibiting tensile force, and the distance between the beam and adjacent steel columns decreases. At low temperatures, the material contracts, exhibiting contractile force, and the distance between the beam and adjacent steel columns increases. Due to the ultra-long length of the building structure, the internal temperature stress of the material is significant.

[0058] Based on the above embodiments, as a preferred embodiment, a pad 11 is provided between the baffle 4 and the upper surface of the corbel 7.

[0059] Specifically, the pad 11 is made of 20mm thick steel plate, and the pad 11 is set at a distance of 50mm from the steel column 2.

[0060] Based on the above embodiments, as a preferred embodiment, to enhance the strength and rigidity of the connection part of the sliding support assembly 1 and prevent the sliding support assembly 1 from being affected by deformation under load, a plurality of stiffening ribs 12 are provided between the baffle 4 and the pad 11, with four stiffening ribs 12 provided on the outer side of each baffle 4, such as... Figure 8 As shown.

[0063] Based on the above embodiments, as a preferred embodiment, a gap is provided between the pad 15 and the steel column 2, which facilitates construction.

[0064] The sliding support assembly in this invention allows for the free release of deformation caused by temperature changes in the beam, preventing the generation of internal forces and eliminating the adverse effects of temperature on safety and aesthetics. Materials undergo thermal expansion and contraction with temperature changes. At high temperatures, the material expands, resulting in tensile force, and the distance between the beam used for temperature stress release and adjacent steel columns decreases. At low temperatures, the material contracts, resulting in contractile force, and the distance between the beam used for temperature stress release and adjacent steel columns increases. Due to the extremely long building structure, the internal temperature stress of the material is significant. This invention directly releases the temperature stress through the sliding support assembly, resulting in significant effectiveness and greater convenience, requiring no additional operations.
