Self-thermal-insulation door smooth rabbet section bar

Abstract

The invention relates to a self-thermal-insulation door smooth rabbet section bar which comprises a hooked rabbet section bar (8). A cavity (2) is formed in the hooked rabbet section bar (8), an installation clamping plate (4) is arranged at the bottom of the cavity (2), a groove (9) is formed in the left lateral wall of the cavity (2), and two inward folded edges (7) are symmetrically arranged at the end of the installation clamp plate (4). The self-thermal-insulation door smooth rabbet section bar is characterized in that a guide groove (5) is formed in the top of the cavity (2), a supporting partition plate (3) is arranged in the cavity (2), the cavity (2) is divided into two parts by the supporting partition plate (3), and each part is filled up with thermal insulation media (6). The self-thermal-insulation door smooth rabbet section bar has the advantages of being simple in structure, convenient to install, firm in structure, good in installation stability and high in thermal insulation due to the fact that the cavity is filled up with thermal insulation materials.

Description

technical field [0001] The invention relates to a metal building material, in particular to a self-insulating door light enterprise profile. Background technique [0002] With the improvement of our country's national economy, people's material and cultural level is also growing. The construction industry, especially the housing construction, is getting bigger and bigger, and the house decoration is also developing in the direction of beauty and practicality. Because aluminum profiles have the characteristics of corrosion resistance, excellent electrical conductivity, thermal conductivity, non-ferromagnetism, excellent machinability, formability, and high recyclability, aluminum materials of different cross-sectional shapes are heated by aluminum rods. Melted and extruded, due to its excellent characteristics, it has become one of the indispensable materials in the industry of architectural decoration and decoration. At this stage, when processing doors and windows, it is u...

Problems solved by technology

[0003] However, the currently used profiles basically adopt a cavity structure, and the gas in the cavity is the same as the outside world, so the gas in the cavity will transfer heat from indoors and outdoors through convection, conduction and radiation. The thermal insulation performance of the profile is very poor, and because the profile is a cavity structure, its support strength is also low, and there are certain safety hazards and other shortcomings when it is used for a long time
