Description

Technical Field

[0001] This utility model relates to the field of pressurized building technology, specifically to a sealed pressure-bearing wall panel and a pressurized building containing the wall panel. Background Technology

[0002] Steel-framed pressurized buildings alter the air pressure and oxygen partial pressure within the building space, effectively bringing the indoor environment to the level of low-altitude regions. This significantly improves oxygen levels in human tissues, eliminates discomfort symptoms caused by altitude sickness, and fundamentally addresses the damage caused by sustained low pressure. It is of paramount importance for ensuring the lives, work, and health of people in high-altitude areas and for promoting the development and construction of these regions.

[0003] Pressure bearing and sealing are fundamental to the pressurization function of pressurized buildings with steel frame structures. Pressurized buildings need to withstand indoor and outdoor air pressure difference loads of 20~50kPa, which places high demands on their structural bearing capacity. At the same time, pressurized buildings must have good airtightness to ensure pressurization effect and energy-saving operation.

[0004] In high-altitude steel structure pressurized building products, wall panels, as one of the main pressure-bearing and sealing components, play a crucial role in ensuring stable air pressure inside the building, resisting the impact of harsh external environments, and ensuring the overall structural safety of the building. Currently, commonly used pressure-bearing wall panels typically employ a combination structure of steel plates and stiffened plates. The main structural form is "lapped rectangular tube + panel + keel + stiffening plate" (the keel and stiffening plate are arranged in a "grid" pattern, meaning that keels and stiffening plates are arranged on both sides of the panel). While this structural form can meet the strength and stiffness requirements of the structure to a certain extent, there are still problems that urgently need to be solved in practical applications: ① Existing wall panels cannot ensure relative sliding between themselves and beams and columns, thus failing to fully meet the seismic safety requirements of the structure.

[0005] ② Overlapping rectangular tubes are uncommon profiles, require secondary processing, are heavy, and occupy indoor space, making them uneconomical and unreasonable; overlapping rectangular tubes have high requirements for installation accuracy and surface flatness, which increases the difficulty of construction.

[0006] ③ The arrangement of the keel and stiffening plates increases the amount of welding work and raises the processing cost; the overall weight of the wall panel causes more inconvenience to on-site installation and construction.

[0007] ④ The sealing method between the wall panel and the beam and column adopts a sealing strip + limiting steel strip. The straightness and spacing requirements are high when welding the steel strip.

[0008] In summary, this utility model provides a sealed pressure-bearing wall panel and a pressurized building containing the wall panel to solve the problems existing in the prior art. Utility Model Content

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0030] Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature.

[0031] Example See Figure 1 and Figure 2This embodiment provides a sealed pressure-bearing wall panel, including a keel 1, stiffening plates 2, a steel panel 3, and overlapping angle steel 4; the keel 1 and stiffening plates 2 are arranged in an alternating manner and fixedly connected by welding to form a skeleton structure, and the steel panel 3 is fixed to the surface of the skeleton structure; preferably, the arrangement of the keel 1 and stiffening plates 2 is a cross-shaped or grid-shaped structure, and the length-to-width ratio L:W of the cross-shaped or grid-shaped structure is 1.5:1-2.0:1; The skeletal structure formed by the keel 1 and the stiffening plate 2 is arranged unidirectionally on one side of the steel panel, which reduces manufacturing and welding costs, lightens the overall weight of the wall, facilitates installation, and improves construction efficiency.

[0032] The lap angle steel 4 is fixed to the edge of the steel panel 3. Preferably, the lap angle steel 4 and the steel panel 3 are connected by weld, and the steel panel 3 is fully welded around its perimeter to ensure the strength and sealing reliability of the connection. The lap angle steel has lower requirements for installation accuracy and surface flatness, which can appropriately reduce the processing accuracy and construction difficulty of steel beams and columns.

[0033] See Figure 1 and Figure 3 The overlapping angle steel 4 is slidably connected to the beams or columns of the pressurized building by bolts 5; the flange of the overlapping angle steel 4 is provided with a plurality of bolt holes 4.1 along its length direction, and the diameter of the bolt holes 4.1 is not less than the diameter D+8mm of the bolt 5, which facilitates the installation of the sealed pressure-bearing wall panel and ensures that there is a certain relative sliding between the sealed pressure-bearing wall panel and the beams or columns 8 of the pressurized building, thus meeting the seismic requirements.

[0034] Preferably, the spacing between multiple bolt holes 4.1 on the same overlapping angle steel is ≤400mm to ensure that the sealing pressure-bearing wall panel can be pressed tightly to ensure a seal.

[0035] See Figure 2 and Figure 3 A sealing structure 6 is provided between the lap angle steel 4 and the beams or columns of the pressurized building to meet the sealing requirements of the pressurized building. The sealing structure 6 includes a sealing strip 6.1 and a limiting gasket 6.2. The sealing strip 6.1 is provided with a reserved hole, and the limiting gasket 6.2 is provided in the reserved hole and forms an interference fit with the reserved hole.

[0036] Preferably, the limiting gasket 6.2 is provided with a through hole for the bolt 5 to pass through, and the limiting gasket 6.2 is fixed to the overlapping angle steel 4 by the bolt 5.

[0037] The thickness of the limiting gasket 6.2 is 0.7-1.0 times the compression of the sealing strip 6.1, to prevent the sealing strip 6.1 from being crushed and causing sealing failure.

[0038] The purpose of setting the limiting gasket 6.2 is to: ① limit the compression deformation of the sealing strip 6.1 and prevent the sealing strip 6.1 from being crushed and causing the seal to fail; ② cooperate with the sealing strip 6.1 to ensure that the bolt 5 is tightened and to prevent the bolt 5 from loosening after repeated pressure filling and depressurization.

[0039] In this embodiment, to improve installation efficiency, the bolt 5 adopts a unidirectional installation structure. An adjustable gap of 3-5mm is provided between the bolt 5 and the beam or column of the pressurized building along the axial direction of the bolt 5. When the bolt 5 is tightened to the point that it cannot be rotated any further, the bolt is rotated counterclockwise 1.5-2.5 turns, so that an adjustable gap of 3-5mm is formed between the bolt 5 and the beam or column of the pressurized building along the axial direction of the bolt 5. This can both press the sealing strip 6.1 and ensure that there is a certain relative sliding between the sealed pressure-bearing wall panel and the beam or column 10, thus meeting the seismic requirements.

[0040] In this embodiment, see Figure 3 A sealing washer 7 is provided between the bolt 5 and the inner side (away from the steel panel) of the beam or column of the pressurized building, and between the bolt 5 and the outer side (the side connected to the steel panel) of the lap angle steel 4. The bolt hole 4.1 is sealed by the sealing washer 7. The structure is simple, easy to install, and does not require welding, thus reducing installation costs and improving work efficiency. The sealing washer 7 and the sealing structure 6 ensure the overall sealing performance of the connection between the sealed pressure-bearing wall panel and the beam or column 8.

[0041] This embodiment also provides a pressurized building, including beams, columns, and a sealed pressure-bearing wall panel as described above. The sealed pressure-bearing wall panel is slidably connected to the beams or columns to meet seismic requirements.

[0042] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
