Problems solved by technology

Because metal has good thermal conductivity, the sub-frames of doors and windows made of metal have become good conductors of heat transfer inside and outside the building, and poor thermal insulation performance is not conducive to the energy saving and heat preservation of buildings.
The sub-frames of doors and windows made of wood have good heat insulation performance, but the wood is easy to rot and deteriorate, resulting in a short service life of the sub-frames of doors and windows, which increases the cost of use; in addition, the increasing scarcity of wood resources has become a global issue sex

Abstract

The invention relates to an auxiliary door / window frame made of biomass composite materials and a manufacturing method of the auxiliary door / window frame. The auxiliary door / window frame has the advantages of good heat insulation, high strength, long service life, simple structure and low cost. The manufacturing method has the advantages of convenience in production, high production efficiency and low cost. The technical scheme includes that the auxiliary door / window frame comprises a rectangular frame structure, two upper raised bars are respectively formed on two sides of the upper end face of an auxiliary frame bar, and a plurality of lower raised bars are formed on two sides of the lower end face of the auxiliary frame bar. The auxiliary door / window frame is characterized in that a plurality of through holes extending in the length direction of the auxiliary frame bar are formed in the auxiliary frame bar. The manufacturing method of the auxiliary door / window frame includes steps of 1), selecting raw materials; 2) sufficiently mixing the above materials and pelleting; 3) placing the pelleted materials into an extruder for extrusion molding; 4) subjecting the molded materials to surface processing and mortise processing and manufacturing the auxiliary door / window frame.

Description

technical field [0001] The invention relates to a building material, in particular to a door and window sub-frame and a manufacturing method thereof. Background technique [0002] The door and window sub-frame is a kind of building material, which plays the role of fixing and protecting doors and windows. When installing doors and windows, the sub-frames of doors and windows are first buried in the wall, then the main frame of doors and windows is installed on the basis of the sub-frames of doors and windows, and finally the doors and windows are installed on the main frame of doors and windows. [0003] Existing door and window sub-frames are generally made of metal materials or wooden materials. Because metal has better thermal conductivity, the sub-frames of doors and windows made of metal have become good conductors of heat transfer inside and outside the building, and poor thermal insulation performance is not conducive to energy saving and heat preservation of buildin...
