Energy-saving profiles and profile processing technology for heat-insulated buildings with strips and broken bridges

Abstract

The invention provides a strip-penetrating broken-bridge heat insulation building energy-saving section bar and a machining process for the section bar. The section bar is formed by single section bars at the inner side and the outer side and a hollow heat insulating strip between the two section bars, the hollow heat insulating strip is in bilateral symmetry centering on a vertical center line, one ends of tooth supports, adjacent to compression tooth rolling torsion surfaces, inwardly incline towards the direction of the vertical center line, included angles are 1 degree to 2 degrees, and compression tooth support surfaces are vertical to the vertical center line. According to the section bar, the cost is reduced, the machining is convenient, the section bar formed by machining is not deformed due to machining, standard-structure section bars capable of preventing structural deformation can be obtained via rolling combination of the single section bars, and the installation problem of the section bar due to deformation in a combination process is eliminated.

Description

technical field [0001] The invention relates to a building energy-saving door and window material, in particular to an energy-saving aluminum profile for a building with strips, heat insulation and broken bridges. Background technique [0002] With the implementation of the national building energy-saving policy, aluminum alloy heat-insulating cold bridge doors and windows are more and more widely used. In the current heat-insulating aluminum profile market, there are mainly two types of heat-insulating aluminum profile production technologies: one is from Europe. Strip heat insulation technology, the other is glue injection heat insulation technology from North America. European strip-through and North American pouring-type heat-insulating aluminum profiles have better heat insulation performance. Compared with the two, the strip-through-type heat-insulating aluminum profiles can easily realize the internal and external double-color door and window system to meet the high a...

Problems solved by technology

[0004] However, in the process of developing the heat insulation profile of a single hollow heat insulation strip, it was found that various single hollow heat insulation broken bridge profiles generally have serious closing deformation after conventional rolling and lamination, which makes the rolling after rolling The overall size of the thermal insulation profile deviates, which not only seriously affects the appearance, but also encounters the problem of inability to fit and install when the profile is installed and matched
