Plastic-steel fire resisting window

Abstract

The invention discloses a plastic-steel fire resisting window. The plastic-steel fire resisting window comprises a PVC profile material, glass, a glass fastening device and a sealing part. The sealing part comprises a sealing rubber strip which is molded through co-extrusion and a high-temperature expansion strip made of a fireproof high-temperature expansion material, and the high-temperature expansion strip is located on the lower portion of the sealing rubber strip; the glass fastening device comprises an L-shaped fixed plate, an L-shaped movable plate, a fixing screw and a cushion cover. According to the plastic-steel fire resisting window, the whole glass fastening device is made of iron or steel, a fastening mechanism positioning the lower end of the glass is formed by the L-shaped fixed plate fixedly connected with a steel lining and the L-shaped movable plate matched with the cushion cover arranged on the L-shaped fixed plate, the fastening mechanism is resistant to high temperature and not prone to deformation, and therefore it is effectively guaranteed that safety protection is provided in time under the conditions that external plastic steel is melted, and the glass is softened. According to the plastic-steel fire resisting window, the high-temperature expansion rubber strip and the sealing rubber strip are molded through co-extrusion and installed at a time when door window machining is conducted.

Description

technical field [0001] The invention relates to the technical field of windows, in particular to a plastic-steel fireproof window. Background technique [0002] PVC plastic doors and windows are a kind of product promoted by the state. Compared with traditional steel windows, wooden windows and aluminum alloy doors and windows, they have greatly improved heat insulation, sound insulation, anti-aging and sealing performance. With the continuous improvement of national building energy-saving policies, the thickness of building exterior wall insulation materials continues to increase, but the insulation materials commonly used in the market are flammable materials, which are prone to fire hazards. The "Code for Fire Protection Design of Buildings" GB 50016-2014 implemented on May 1, 2015 puts forward specific requirements for the fire performance of building doors and windows, and requires the realization of two performances of energy saving and fire protection for doors and wi...

With the continuous improvement of national building energy-saving policies, the thickness of building exterior wall insulation materials continues to increase, but the insulation materials commonly used in the market are flammable materials, which are prone to fire hazards

The "Code for Fire Protection Design of Buildings" GB 50016-2014 implemented on May 1, 2015 puts forward specific requirements for the fire performance of building doors and windows, and requires the realization of two performances of energy saving and fire protection for doors and windows. The cost of performance is high, and because the plastic steel profile itself has poor high temperature resistance, once softened and deformed, the glass cannot be positioned, resulting in the glass falling and causing the fire prevention function to fail
