Fireproofing closed observation window

Abstract

The invention relates to a fireproofing closed observation window. The fireproofing closed observation window comprises an observation window frame and observation window glass, wherein the observation window frame is embedded in an observation hole of a closed partition wall and comprises an embedded anchor bar embedded in the closed partition wall, an observation window frame base which is welded with the embedded anchor bar and has an L-shaped cross section and a high strength pressure plate which is welded with the observation window frame base; the observation window glass is fixedly connected on the observation window frame and comprises internal high strength fireproofing glass and external high strength fireproofing glass; the peripheral sides of the internal high strength fireproofing glass are clamped in an internal fireproofing rubber composite board; and the peripheral sides of the external high strength fireproofing glass are clamped in an external fireproofing rubber composite board. The window has integrated fire prevention, airtight and perspective functions, realizes the airtight and perspective functions while meets the performance requirements of first-grade fireproofing windows, and can be directly assembled on the observation hole of the closed partition wall of a room for civil airdefense construction equipment.

Description

technical field [0001] The invention relates to an observation window installed on an observation hole of a closed partition wall in an engineering equipment room. Background technique [0002] With the continuous development of science and technology, the corresponding technical indicators in the civil air defense engineering design specifications are also gradually improved, so higher requirements are put forward for the various performances of protective equipment, especially in the airtight compartments of some engineering equipment rooms. The airtight observation window at the wall, in addition to meeting the airtight and perspective requirements, is also required to meet the performance requirements of Class A fire windows. [0003] However, the existing airtight observation window only has a certain airtight and see-through performance, and the fire prevention function is not considered in the design, and its main material cannot be heat-insulated and fire-proof, and ...
