Problems solved by technology

Its main disadvantages are: 1. The section of the steel profile is large, which is not economical and makes the doors and windows too heavy, which is not easy to install.
2. The T-bend radius of the "U" groove on the edge of the profile is small, which is not conducive to eliminating the deformation stress of the steel, but also has problems such as difficult manufacturing and hidden quality problems
3. When the door and window products are assembled, the connection between the frame and the fan profile is welded, the production efficiency is not high, and it is not conducive to large-scale promotion and popularization

Abstract

The present invention discloses a composite profile for thermal bridge solid-web steel doors and windows and a manufacturing method, relating to a steel door and window profile and a manufacturing method. The profile provided by the invention consists of a solid-web steel profile made from standard steel member and a nonmetallic heat insulation strip. The manufacturing method is that: firstly one to seven kinds of standard steel members are manufactured; secondly two standard members are seam welded into eight kinds of solid-web steel profiles; then two kinds of the solid-web steel profiles and one nonmetallic heat insulation strip are assembled into six kinds of composite profiles for thermal bridge solid-web steel doors and windows; and finally the coating and the assembly are carried out. Due to the small cross section, light weight, high strength, steel material saving and convenient assembly of the steel member, the profile provided by the present invention has the advantages of good heat insulation performance and high quality. The present invention also has the advantages of simple method, low equipment investment, standardized manufacture of the steel member, high efficiency and convenient popularization and application. Thus the present invention can be widely applied in the composite sections for thermal bridge solid-web steel doors and windows for the flat-opening door and window, the sliding door and window, the fixed window, the top-hinged swinging window and the manufacture.

Description

1. Technical field [0001] The invention belongs to the technical field of steel doors and windows, and in particular relates to steel door and window profiles and a manufacturing method thereof. 2. Background technology [0002] Before the 1980s, steel doors and windows accounted for about 70% of the market share in my country's metal doors and windows. Among them, the series of solid-web steel doors and windows played a huge role in workshops, factories, and civil buildings in various industries. . After the 1980s, with the rapid development of my country's national economy, the old standard steel doors and windows were gradually eliminated. There are a large number of public buildings, industrial buildings, residential buildings and country villas using high-performance and high-quality steel doors and windows. However, the steel doors and windows used in developed countries are no longer steel doors and windows with simple structure and low performance. Steel windows and d...
