High-precision bridge-cutoff heat-insulation steel profile and manufacturing method thereof

Abstract

The invention discloses a high-precision bridge-cutoff heat-insulation steel profile and a manufacturing method thereof, and relates to manufacturing methods of a heat-insulation steel profile in a bridge-cutoff heat-insulation steel door and window composite profile. The high-precision bridge-cutoff heat-insulation steel profile comprises a profile I, a profile II and a heat-insulation adhesive tape. The manufacturing method comprises the following steps that different profiles I and profiles II are manufactured, and then the profile components form the composite profile by installing the heat insulation adhesive tape. The steel component is light in weight and high in strength, steel is saved, installation is convenient, and the profile is good in heat insulation performance and high inquality; The method is simple, low in equipment investment, high in efficiency and convenient to apply and popularize and has the advantages of saving time, labor and materials, being simpler and moreconvenient in production process, good in social benefit and beneficial to wide application and popularization, and the bridge-cutoff heat-insulation steel profile manufactured through the method isgood in bending resistance and low in manufacturing cost.

Description

technical field [0001] The invention relates to a method for manufacturing heat-insulating steel profiles in composite profiles of heat-insulating steel doors and windows for broken bridges, in particular to a high-precision heat-insulated steel profile for broken bridges and a manufacturing method thereof. Background technique [0002] Since the beginning of the 21st century, the application of broken bridge insulation profiles in buildings has gradually developed in our country. Its main characteristics are the advantages of high thermal insulation and environmental protection. With the rapid development of my country's national economy, building fire protection is becoming more and more important. Due to its unique material characteristics, ordinary broken bridge insulation aluminum profiles cannot resist ultra-high temperature fires, cannot meet the requirements of buildings for fire protection, and their safety cannot be guaranteed. Thereby it is gradually eliminated in ...
