Multi-functional steel-aluminum composite door window system

Abstract

The invention relates to aluminum steel compound door windows, in particular to a multi-functional steel-aluminum composite door window system. The multi-functional steel-aluminum composite door window comprises a window frame, a middle stile, a window sash frame and supporting glass, a lock and hinges, and the window frame and the window sash frame are connected through the hinges; and window frame profiles, middle stile profiles and window sash profiles comprise broken bridge aluminum profiles and steel skeletons, the steel skeletons penetrate into the broken bridge aluminum profiles, fixedscrews are hammered on the surfaces of the steel skeletons in a whole row mode, finally, surface decoration aluminum profiles penetrate to form a steel-aluminum composite profile, middle stile connecting pieces at the crisscross place of the middle stile are connected with through middle stile pulling rods and eccentric screws. According to the multi-functional steel-aluminum composite door windowsystem, the cost is low, environmental protection is achieved, and the door window system design of multiple functions of heat preservation, heat insulation, sound insulation, water resistance, fireprotection and the like is achieved; and the door window system is attractive and elegant, sturdy and durable, various in function, environmentally-friendly in material and recyclable, and confirms tothe regulatory requirement of nation for green buildings.

Description

Technical field [0001] The invention relates to aluminum-steel composite doors and windows, in particular to a multifunctional steel-aluminum composite door and window system. Background technique [0002] Based on the requirements of relevant national standards and specifications, fire-resistant windows must meet the requirements of fire-resistant grades. In addition, as building doors and windows must meet the requirements of airtightness, watertightness, sound insulation performance and building energy efficiency of building doors and windows at the same time, the existing building doors and windows on the market have various shortcomings: [0003] 1) Broken bridge aluminum profile doors and windows are made of broken bridge aluminum profiles and double or multi-layer glass, which have good air and water tightness and meet the basic requirements of building doors and windows. However, the melting point of aluminum profiles is 660 degrees, which cannot meet fire resistance. The ...

AI Technical Summary

Problems solved by technology

[0003] 1) Broken bridge aluminum profile doors and windows are made of broken bridge aluminum profiles and double or multiple layers of glass, which have good air and water tightness and meet the basic requirements of building doors and windows. However, the melting point temperature of aluminum profiles is 660 degrees, which cannot meet the requirements of fire resistance. The test temperature requirement of 1150 degrees cannot meet the requirements of fire-resistant integrity of building fire-resistant windows.

[0004] 2) Plastic-steel profile doors and windows are made of plastic profiles and double or multiple layers of glass, which have good air and water tightness and meet the basic requirements of building doors and windows. Requirements for fire integrity of windows

[0005] 3) The existing steel insulation steel doors and windows systems on the market are complex in design, especially the imported polymer insulation materials, which are extremely expensive, and ordinary buildings cannot afford their high prices, while steel non-insulation doors and windows are also Can not meet the requirements of fire protection and heat insulation at the same time
