[0002] Energy-saving and environmentally friendly prefabricated building structures refer to building structures that are assembled on site through factory prefabricated components. Compared with traditional buildings, prefabricated buildings transfer a large amount of on-site work to the factory, and assemble and fix them on site through reliable connections to form a complete building structure. This type of building is generally assembled for the purpose of energy saving and environmental protection. However, the existing energy-saving and environmentally friendly prefabricated building structures have some shortcomings, such as: Application number: CN202011172411.0 A method for the construction of an assembled steel structure building, which combines passive technology with an assembled construction method to improve the thermal insulation and moisture retention performance of mobile buildings, has the advantages of reducing heat loss, environmental protection and energy saving, convenient and fast construction, and functionality that meets social use needs. However, in actual use, it is difficult to support the opening in the wall and to limit the position of the opening, which may cause deformation of the opening, reducing the strength of the device when in use; Therefore, we proposed an energy-saving and environmentally friendly structure for prefabricated buildings in order to solve the above-mentioned problems. Summary of the invention

[0005] By arranging a column mechanism on the top of the fixed base plate, the fixed base plate can be more stable when fixing the first wall and the second wall, and it can be more convenient during the installation or disassembly process. By setting the opening mechanism, the opening mechanism can support the position of the doors and windows, thereby preventing deformation at the opening in the wall, increasing the stability and firmness of the structure during assembly, and making it more convenient to disassemble the equipment.
