Door and window frame assembly, building wall and building body

Abstract

The invention provides a door and window frame assembly, a building wall and a building body, and relates to the technical field of buildings. The door and window frame assembly comprises a frame component used for forming a door frame or window frame, the frame component comprises a top frame, a bottom frame and at least one side frame which are connected, a first inserting structure is arrangedon the outer side face of the side frame, the outer side face of the top frame and / or the outer side face of the bottom frame are / is provided with second inserting structures, the second inserting structure of the bottom frame is used for being in inserted fit with a preset bottom table plate, and a first limiting part is arranged on the outer side face of the side frame. According to the technical scheme, the first limiting part on the outer side face of the side frame can be connected with a preset end wall protection plate in a limited connection manner, the end wall protection plate can belimited from being separated from the side frame, and it is ensured that after the side frame and the end wall protection plate are in inserted assembly through the first inserting structure, the first limiting part can be used for ensuring the assembly stability.

Description

technical field [0001] The invention relates to the technical field of buildings, in particular to a door and window frame assembly, a building wall and a building. Background technique [0002] According to the "China Building Energy Consumption Research Report (2017)" released by the China Building Energy Conservation Association, housing construction consumes 1 / 3 of the country's steel, 60-70% of cement, and 1 / 3 of the city's Construction land, 1 / 3 of urban water, 40-50% of energy, has a huge impact on energy, resources, and the environment. The traditional construction industry is a high-pollution, high-energy-consuming, and environmentally unfriendly industry. Its industrialization level is low, and its water consumption, energy consumption, artificial waste, and sewage discharge are large, which does not conform to the sustainable development policy of the country for energy conservation and environmental protection. A lot of labor is required. [0003] In recent yea...
