Abstract
Description
Technical Field
[0001] This utility model belongs to the field of pressure-bearing building structure technology, and relates to a pressure-bearing wall panel structure. Background Technology
[0002] The harsh environment of low pressure, hypoxia, and extreme cold in plateau regions severely restricts economic and social development. Pressurized buildings, by altering the air pressure and oxygen partial pressure within the building space, bring the indoor environment to the level of low-altitude areas, effectively improving the hypoxic state of human tissues, eliminating the discomfort symptoms caused by altitude sickness, and fundamentally solving the problem of continuous low-pressure damage. This is of great significance for ensuring the lives, work, and health of people in plateau regions and for promoting the development and construction of these areas.
[0003] Pressure resistance and sealing are fundamental to the pressurization function of pressurized buildings. Pressurized buildings need to withstand indoor and outdoor air pressure differences of 20-50 kPa, 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 pressurized building products, wall panels, as one of the main pressure-bearing and sealing components, play a crucial role in ensuring stable air pressure within 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, specifically in the form of "lapped rectangular tubes + main and secondary keels + panel + stiffening plates" (where both keels and stiffening plates are arranged in a "grid" pattern). 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:
[0005] 1. Overlapping rectangular tubes are heavy and take up indoor space, which increases costs and is not economical.
[0006] 2. The use of grid-shaped stiffening plates increases the amount of welding and raises processing costs.
[0007] 3. Overlapping rectangular tubes require high installation accuracy and surface flatness, which increases the difficulty of construction.
[0008] 4. The wall panel is heavy, which makes on-site installation difficult.
[0009] In summary, there is still considerable room for improvement in terms of weight, structural form, and materials for current wall panels. Utility Model Content

[0015] Furthermore, the honeycomb panel includes a first composite layer, a honeycomb core layer, and a second composite layer connected sequentially from top to bottom;
