Fireproof bridge-cutoff aluminum alloy casement window

Abstract

The invention discloses a fireproof bridge-cutoff aluminum alloy casement window. The fireproof bridge-cutoff aluminum alloy casement window is characterized in that inward opening sashes, a glass fixing sash glass pressing strip, a window frame, a window beam, corner connectors, heat insulation and fire prevention glass, inflaming retarding sealing rubber strips, inflaming retarding weather strips, an unlocking device, glass fixing supports, outer frame reinforcing steel sheets, cavity steel bushes, sash reinforcing steel sheets, steel bush corner connecting sheets, stainless steel screws, glass periphery clearance parts, refractory glass cushion blocks, fireproof expansion strips, fireproof silver, cavity injection mud and fireproof sealant. The fireproof bridge-cutoff aluminum alloy casement window is high in overall strength and good in overall fire prevention and sound insulation effect, the overall heat conduction performance of a heat insulation bridge-cutoff aluminum alloy profile is lower than that of a common aluminum alloy profile, the fire prevention and heat insulation effect is better, the inflaming retarding sealing rubber strips and the inflaming retarding weather strips have the performance of fire prevention, inflaming retarding and water prevention, and the fireproof bridge-cutoff aluminum alloy casement window is suitable for being used and popularized on various buildings with high fireproof performance requirements.

Description

technical field [0001] The invention relates to the field of broken bridge aluminum alloy casement windows, in particular to a fireproof broken bridge aluminum alloy casement window. Background technique [0002] With the continuous development and progress of society, the composition materials used in various domestic buildings have continuously increased the requirements for overall fire safety performance. However, ordinary fire windows have the following problems in actual use: 1. The outer frame of the glass steel bracket without solidification strengthens the steel sheet fan and strengthens the steel sheet steel lining corner connection piece assembly, which has poor overall stability, especially serious deformation at high temperature; 2. , The heat-insulating fire-resistant glass and the bottom of the aluminum alloy profile in the window frame window have poor contact strength and poor fire resistance; 3. There is no flame-retardant sealing strip on the contact part ...
