Fireproof and soundproof fixed window

Abstract

The invention relates to a fireproof and soundproof fixed window. The fireproof and soundproof fixed window comprises an outer frame and an inner frame, the cross sections of the outer frame and the inner frame are respectively shaped like L and 7, fireproof plate strips are arranged between horizontal edges of the outer frame and the horizontal edges of the inner frame, and the horizontal edges of the outer frame, the fireproof plate strips and the horizontal edges of the inner frame are connected together with the help of bolts. Pressure plates are arranged outside vertical edges of the inner frame, and the two are connected together with the help of screws. The width of the horizontal edges of the outer frame is larger than that of the horizontal edges of the inner frame, so that the horizontal edges of the outer frame, the vertical edges of the inner frame and the pressure plates commonly constitute an annular slot. A compound fireproof glass plate is arranged in the annular slot, and flame-retardant rubber strips are arranged on two surfaces on the periphery of the fireproof glass plate. The structure is characterized in that a protective glass plate is arranged on the outer surface of the compound fireproof glass plate, and a spacing interval for forming a hollow layer is arranged between the protective glass plate and the compound fireproof glass plate. The fireproof and soundproof fixed window has good soundproof effect and no limitations on the using range. The fireproof and soundproof fixed window is particularly applicable to ships.

Description

technical field [0001] The invention relates to a ship window. Specifically, it is a fixed window with fireproof and sound insulation properties, especially suitable for ships. Background technique [0002] At present, the fixed windows on ships are composite fire-resistant glass panels composed of two layers of tempered glass bonded together with transparent fire-resistant glue. This kind of window has fireproof and watertight properties, but because the composite fireproof glass panel is composed of only two layers of tempered glass glued together with transparent fireproof glue, the sound insulation effect is poor, less than 30dB, and it is difficult to meet the requirements of the central control room of the ship's engine room. Sound insulation requirements, the scope of use is limited. Contents of the invention [0003] The problem to be solved by the present invention is to provide a fireproof and soundproof fixed window. This kind of fire-proof and sound-proof fi...
