Description

Fire-resistant window

Technical Field

The invention relates to the technical field of building decoration, in particular to a fire-resistant window.

Background

The building external window is a relatively important component in the whole building, plays a very important role in improving the functions and the quality of the building, but is the weakest component in the whole building, and particularly when the building has a fire, the common external window is difficult to effectively protect the indoor environment, and the fire enters the indoor environment along the external window, so that a great amount of casualties are caused. According to tens of thousands of fire disastrous training, the fire-resistant building insulation material has definite combustion performance according to different heights. The common external window firstly needs to meet the six properties of the external window, thermal property, wind pressure resistance, watertight property, airtight property, sound insulation property and lighting property. The fire window is different from a common outer window, the fire window needs to meet fire resistance and heat insulation performance and fire resistance integrity, and the sexuality of the common outer window is difficult to meet. The new outer window meeting the fire-resistant integrity proposed by the new construction rule for the first time actually puts forward new requirements on the common outer window, namely, the six properties of the common outer window are required to be met, and the fire-resistant integrity requirement of the fire-resistant window is also required to be met, so the new outer window is named as the fire-resistant window in the future industry.

The current chinese utility model patent that can refer to the grant publication number for CN209510111U discloses a fire-resistant effectual fire-resistant window, including fire-resistant frame, first cavity has been seted up to fire-resistant frame's inside, the inside fixed mounting sponge that absorbs water of first cavity, the through-hole with first cavity intercommunication is seted up to fire-resistant frame's inner wall, fire-resistant frame's left side intercommunication has the fire-resistant connection water pipe. This fire-resistant effectual fire-resistant window, fire-resistant frame through setting up, the first cavity of seting up on the fire-resistant frame, realized when the conflagration breaing out with water piping connection to fire-resistant frame on the fire-resistant connection water pipe of intercommunication, make water flow into in the first cavity through fire-resistant connection water pipe and absorbed by the sponge that absorbs water, realized guaranteeing to constantly cool down to fire-resistant frame, discharge in the through-hole of seting up on the fire-resistant frame through the steam of water simultaneously, it is moist to have realized cooling down to fire-resistant window's whole, thereby it is long when the fire-resistance of fire-resistant window has been improved, it reaches fire-resistant effectual purpose to have made things convenient for fire.

Although the prior art scheme among the above-mentioned can reach fine fire-resistant effect, but must guarantee just can produce the effect when the window form is closed, but the above-mentioned self-closing that can't realize the window form, under this kind of state, in case nobody notices in the house, and the window form external world when having fired big fire, the unable self-closing of window form is in the open mode, and time is long, and flame will directly stretch to indoor to lead to huge danger, and then lead to very big danger.
