Load-bearing and thermal insulation integrated wall panels for low-rise and multi-story rural houses Technical requirements for connecting accessories

1 Scope

GB/T 46826-2025 is the Chinese national standard covering the wall panel that carries the load and insulates in one element - with the connections between panels and to the floors, which is where a prefabricated house either behaves as a structure or does not. First edition, with GB/T 46824-2025 and GB/T 46825-2025. Issued on 2 December 2025, it has been in force since 1 July 2026.

This document specifies the classification, specifications, and marking of load-bearing and thermally insulated integrated wall panels and connecting accessories for low-rise and multi-story rural houses. General rules are required. The requirements, inspection rules, marking, storage and transportation are described, along with the corresponding testing and inspection methods. This document applies to load-bearing and thermal insulation integrated wall panels for low-rise and multi-story rural houses with 6 stories or less and a building height not exceeding 24m. And the production and inspection of connecting parts.
