Description

TECHNICAL FIELD

[0001] The present application relates to the field of wallboard disassembly structure, especially to a steel structure substation detachable wallboard system and its disassembly method. BACKGROUND

[0002] With the continuous development of power systems and the acceleration of urbanization process, as an important hub of power transmission and distribution system, the construction standard and operation management level of substations are constantly improving. In recent years, the concept of standardized design has been widely applied in the construction of substations, especially the popularization and application of integrated outer wall system, which not only improves the overall aesthetics and structural safety of substations, but also effectively reduces the impact of noise on the surrounding environment by integrating sound-absorbing materials, meeting the relevant requirements of environmental protection and energy saving.

[0003] However, the existing integrated outer wall system is mostly non-detachable or difficult to disassemble, and the connection between the wallboard and the main structure is firm, making it difficult to achieve quick and non-destructive disassembly and reuse. In the subsequent expansion and reconstruction of substations, production technology transformation and other projects, it is often necessary to temporarily remove part of the outer wall to facilitate the transportation, installation or replacement of large equipment. The existing wall structure generally has the following problems in such scenarios:

[0004] Firstly, the wallboard structure cannot be disassembled reversibly, and it is difficult to restore its original state after disassembly, making it impossible to achieve secondary utilization, resulting in material waste and increased costs. Secondly, the disassembly process is complicated and requires a large amount of manual and mechanical cooperation, with a long construction period, affecting the normal operation of the substation and the project progress. Thirdly, the wallboard and its connecting parts are easily damaged during disassembly, reducing the safety and reliability of the structure for subsequent use. In addition, the sealing performance of the existing outer wall system is difficult to guarantee after reinstallation, and problems such as water seepage and air leakage are likely to occur, affecting the operating environment of the substation and the safety of the equipment.

[0005] With the increasing demand for prefabricated buildings and efficient construction in new infrastructure projects, the existing outer wall system has been difficult to meet the diversified needs of quick disassembly, reuse and efficient sealing. Especially in the context of frequent equipment replacement, technology upgrade or expansion and reconstruction of substations, how to achieve efficient and non-destructive disassembly and reuse of the outer wall has become a technical problem that needs to be solved.

[0006] For example, the invention with publication number CN111779162A discloses a method for manufacturing a modular steel structure substation detachable wall, which realizes the overall disassembly of part of the outer wall by adding detachable auxiliary keels. However, it needs to pre-set the detachable area, and only allows the wallboard in the specified area to be disassembled subsequently, which limits the design of expansion and reconstruction projects, and the special keels of the detachable area are different from the standard keels, which has a certain impact on the cost and installation efficiency.

[0007] The application with the publication number CN111636638A discloses a detachable wallboard system and its installation and disassembly methods, which fix the position of the wallboard through fasteners passing through the wallboard, and realize detachable connection between the wallboards by using rotatable pressing plates, but such wallboard system is not suitable for fabricated steel structures.

[0008] The application with the publication number CN111926949A discloses a connecting structure of a prefabricated wallboard and a fabricated steel frame structure beam and its construction method, which indirectly connects the wallboard and the steel structure beam through an L-shaped connecting piece and bolts. Although such connecting structure is easy to disassemble and install the wallboard, a large number of bolts need to be screwed from the inside when disassembling, which is still relatively cumbersome.

[0009] Therefore, there is an urgent need to develop a new type of substation outer wall system which is reasonable in structure, convenient to disassemble and assemble, reusable, and has good sealing performance, so as to meet the actual needs of substations in various application scenarios such as reconstruction and expansion, production technical transformation, reduce construction cost, reduce resource waste, and improve the operation safety and management convenience of substations.
