Door and window energy-saving auxiliary frame and production technology thereof

Abstract

The invention discloses a door and window energy-saving auxiliary frame which comprises an auxiliary frame body. The longitudinal cross section of the auxiliary frame body is rectangular. A plurality of separation strips are arranged in the middle of the auxiliary frame body. An inner cavity of the auxiliary frame body is separated into a plurality of heat insulation cavities. A steel liner is arranged on the inner wall of each heat insulation cavity. The steel liners are fastened to the inner walls of the heat insulation cavities through screws. A plug pin is arranged at one end of the auxiliary frame body. The production technology of the door and window energy-saving auxiliary frame comprises the following steps of 1, sectional material cutting, 2, steel liner assembling, 3, welding, 4, corner cleaning and adhesive tape assembling, and 5, finished product quality inspection , packaging and storage. The steel liners are installed on the inner walls of the heat insulation cavities of the auxiliary frame through the screws, assembling is easy and convenient, the heat insulation function of the auxiliary frame sectional material and the compressive strength of the steel liners are perfectly combined, the requirement for energy conservation can be met, and the requirement for the mechanic performance can be met. The production technology of the auxiliary frame is simple and convenient and fast to operate, and the produced auxiliary frame has the good heat insulation effect, stable structure and more attractive appearance.

Description

technical field [0001] The invention relates to the technical field of energy-saving frame products, in particular to an energy-saving frame for doors and windows and a production process thereof. Background technique [0002] The frame attached to the door and window plays a role in determining the size and positioning of the door and window. Generally speaking, after the openings of the doors and windows of the building are built, the size is not standardized. After installing the attached frame, the processing size of the doors and windows can be measured more accurately, which is also conducive to the installation of the doors and windows, and the safety is better. At the same time, the use of attached frames reduces the expansion and contraction of plastic doors and windows due to thermal expansion and contraction.

AI Technical Summary

Problems solved by technology

[0003] There are many types of door and window installation, and some are installed without attached frames, which are directly fixed on the concrete structural surface. The installation accuracy is not guaranteed, and it is easy to seep water

At the same time, the installation needs to be installed in conjunction with the civil structure. During the installation process, each process is cross-constructed, which is easy to damage the window frame and is not conducive to the protection of the finished product.

Some use steel pipes to weld the attached frame, which is easy to rust after being exposed to water, which affects the firmness, and the heat transfer coefficient of the steel attached frame is high, and has no energy-saving characteristics

There are also some wood-plastic attached frames, which have better energy-saving performance, but the cost is higher
