Energy-saving and environment-friendly heat-insulation fireproof window

Abstract

The invention relates to an energy-saving and environment-friendly heat insulation fireproof window which comprises a window frame, a window sash and fireproof glass, wherein the window frame and the window sash are filled with the fireproof glass. Each of the window frame and the window sash comprises an outer frame profile, an inner frame profile and a connecting piece arranged between the inner frame profile and the outer frame profile; a first accommodating cavity is formed among the inner frame profile, the outer frame profile and the connecting piece; a first fireproof expansion rod is accommodated in the first accommodating cavity; the inner frame profile, the outer frame profile and the connecting piece are each provided with a plurality of through holes communicating with the first containing cavity. The first fireproof expansion rod expands at high temperature so that part of the first fireproof expansion rod can be extruded out of the through hole and attached to the inner frame profile, the outer frame profile and the side, away from the first containing cavity, of the connecting piece. The fireproof window has the effects of energy conservation, environmental protection, good heat insulation performance and good fireproof performance.

Description

technical field [0001] The present application relates to the field of fireproof windows, in particular to an energy-saving and environmentally friendly heat-insulating fireproof window. Background technique [0002] A fire window is a window whose frame can meet the requirements of fire resistance and fire integrity within a certain period of time. Generally, the openings or skylights on the outer wall of the building where the fire separation distance is insufficient, the parts that need to be observed on the firewall or the fire partition wall in the building, and the openings of the outer wall that need to prevent the vertical spread of fire, when the space separated by the firewall Fire windows are also installed when lighting and ventilation are required. [0003] A fire window consists of a window frame and a sash mounted within the window frame, which is usually hingedly mounted within the window frame. In order to facilitate the installation of fireproof windows, ...

Problems solved by technology

However, when a fire breaks out near the doors and windows, due to the limited materials of the existing doors and windows, deformation and damage are likely to occur under high temperature conditions, resulting in a sharp decline in the stability of the fire-resistant windows, and the gradual increase in gaps, which in turn leads to a significant decrease in sealing performance. In severe cases, the window sash The glass inside will fall off directly, seriously affecting the fire resistance of the fire window
