Description

Technical Field

[0001] The invention relates to a forming method of a damage-free and reusable air-rib membrane structure, belonging to the technical field of building structures. Background Art

[0002] Compared to traditional air-supported membrane structures, air-ribbed membrane structures allow for ventilation through openings, local air rib replacement, and assembly, installation, and disassembly. Unlike the low internal pressure of air-supported membrane structures (typically 300-500Pa), the air rib units in air-ribbed membrane structures are high pressure (up to 5,000-10,000Pa). Failure of these units can cause explosions, potentially injuring nearby personnel.

[0003] During the molding process of traditional large-span air-ribbed membrane structures, the inflatable devices on both sides of the air-ribbed units are insufficient to fully mold the air ribs. Traditional methods rely on manual lifting tools, large-scale mechanical lifting, and other methods to provide support points. In addition, air-ribbed membrane structures are assembled from independent air-ribbed units. When an air-ribbed unit needs to be inspected and repaired, the traditional method relies on large-scale mechanical equipment to provide a platform. The above methods have the following major problems:

[0004] The use of manual lifting tools and large machinery increases construction costs and violates environmentally friendly construction principles. It can also damage the air rib membrane material by puncturing, impacting, or squeezing it, potentially causing the high-pressure air rib unit to explode. Furthermore, large-span air rib units are formed by direct inflation from both sides, which can cause local bending, leading to excessive internal pressure and increasing the risk of explosion during the forming process. Summary of the Invention

[0005] The present invention aims to provide a method for forming a non-destructive, reusable air-ribbed membrane structure. Specifically, the method employs air-supported membrane units as auxiliary supports to achieve the desired non-destructive, reusable air-ribbed membrane structure. The present invention is suitable for controlling the formation, maintenance, or testing of air-ribbed membrane structures of varying spans.

[0006] The present invention is based on the auxiliary support measures of air-ribbed membrane structures that are damage-free and reusable based on air-supported membrane structure units. The whole is composed of a support module, an inflation device and a bottom connecting device. The support module is composed of single or multiple air-supported membrane structure units. Through a series of optimized designs on the arrangement, number and inflation method of the air-supported membrane structure units, a global or local auxiliary support platform is provided for the forming, maintenance and inspection of the air-ribbed membrane structure through the inflation of the support module. After completing the supporting function, the support module, the inflation device and the bottom connecting device can be disassembled and evacuated, thereby realizing the reusable auxiliary support measures. The technical solution is a designable, damage-free and reusable measure, which is suitable for large-span air-ribbed membrane structures, and has high rationality, economy, safety and environmental protection, and is easy to promote and use.

[0007] The present invention provides a method for forming a damage-free and reusable air-ribbed membrane structure based on an air-supported membrane structure unit, comprising the following steps:

[0008] (1) A support module is provided as an auxiliary support member, wherein the support module includes a single or multiple air-supported membrane structure units; the air-supported membrane structure units are connected to an inflation device and a bottom connection device, and the support module is inflated by the inflation device. The support module is arranged below the air-ribbed membrane structure and fixed by the bottom connection device.

[0009] Furthermore, there is no mutual connection between the support module and the air-ribbed membrane structure. The air-ribbed membrane structure is supported by the air-supported membrane structure, relying on the lifting capacity of the lower inflatable membrane structure.

[0010] The inflation of the support module provides auxiliary support for the forming, maintenance and inspection of the air-ribbed membrane structure.

[0011] (2) The supporting module, the inflation device and the bottom connection device can be disassembled and removed after use, thereby realizing the reusability of the supporting measures air-supported membrane structure unit.

[0017] Step 4: Deflate the support module through the inflation device and remove the inflation device;

[0018] Step 5: Disassemble the bottom connecting device and evacuate the bottom connecting device;

Ensure that the support modules composed of air-supported membrane structure units can provide effective support for the forming, maintenance and inspection of air-ribbed membrane structures, and realize the reuse of support modules in multi-scale air-ribbed membrane structure projects.

[0027] Furthermore, the inflation device includes an air pump, an air supply pipe, and a pressure sensor; the air supply pipe is equipped with an inflation valve and an air release valve; the arrangement, number, and service life of the inflation device match the arrangement, number, and service life of the air-supported membrane structure units. This design ensures that the inflation device required for the formation of the air-supported membrane structure units is available and can be installed and removed together with the air-supported membrane structure units.

Design the inflation method for support module 1 based on the forming control of air-ribbed membrane structure 4 (observe the forming process during inflation and adjust the inflation rate at any time). After the auxiliary support function is completed, deflate support module 1, and disassemble inflation device 2, bottom connection device 3, and support module 1 in sequence.

[0063] When auxiliary support measures are used for global maintenance and inspection of air-ribbed membrane structures, support module 1, inflation device 2, and bottom connection device 3 are placed beneath air-ribbed membrane structure 4. The inflation pressure of support module 1 is designed based on the required rigidity for maintenance and inspection of air-ribbed membrane structure 4.
