Description

Technical Field

[0001] This utility model relates to the field of prefabricated house technology, and in particular to a wall connection structure for prefabricated light steel prefabricated houses. Background Technology

[0002] Light steel prefabricated houses are a new type of environmentally friendly and economical mobile home that uses light steel as the frame, sandwich panels as the enclosure material, standard modular series for spatial combination, and bolted connections for the components.

[0003] For example, the authorization announcement number "CN221321368U" is titled "A Prefabricated Light Steel Prefabricated House Wall Connection Structure." While the concrete base ensures structural stability after the color steel plate base is installed, and the base allows for the installation of multiple color steel plate columns, the use of color steel plate columns, slots, and self-tapping screws facilitates the installation and disassembly of sandwich panels. The H-shaped metal clips allow for the interlocking connection of multiple sandwich panel sections, and the small size of these sections facilitates transportation, thus effectively improving the efficiency of prefabricated house installation and disassembly and facilitating transport. However, the color steel plate base and columns are fixed by welding, a complex welding process that hinders the recycling of the color steel plate columns. Furthermore, the lack of a load-bearing plate on the wall means that if equipment is installed inside the prefabricated house, the load-bearing capacity relies solely on the color steel plate columns, making it inconvenient to use. Utility Model Content
