Weld fixed fire-resistant porthole
Technical field
The utility model relates to a kind of fire window, a kind of specifically fixed fire-resistant porthole of welding that is applied to the A0 level on the boats and ships.
Background technology
The fire proof construction of fire-resistant window commonly used adopts the fire prevention asbestos cord now, at the heat-barrier material ceramic wool of esconson filling.Inboard around the window frame is provided with the continuous groove of a 20mmX4mm, installs for the fire prevention asbestos cord.The fire prevention asbestos cord coefficient of prevent fires in the long-term ageing process reduces gradually, and the dust that produces in ageing process causes injuring to crewman's skin.
The utility model content
The purpose of this utility model provides the fixed fire-resistant porthole of a kind of welding, solve fire prevention asbestos cord that above-mentioned fire window structure adopts long-term use aging after, the problem that the fire prevention coefficient reduces.
The purpose of this utility model is to be achieved through the following technical solutions:
Weld fixed fire-resistant porthole, fixed fire-resistant window, comprise master window frame, PLASTIC LAMINATED, flame resistant glass, PLASTIC LAMINATED and flame resistant glass are installed on the master window frame, PLASTIC LAMINATED is fixed on the master window frame with press box, the marginal position of flame resistant glass is a PLASTIC LAMINATED, flame resistant glass is fixed on the master window frame with pressing plate, junction in flame resistant glass and master window frame, PLASTIC LAMINATED is provided with aluminosilicate refractory fiber, the side of waring oneself in front of a fire in the flame resistant glass junction is provided with fire-resistant, the back-fire side space is filled with caulking gum, and described flame resistant glass is the individual layer implosion guard.
The further design of such scheme is that master window frame is designed to square.
Perhaps, selectable, master window frame is designed to circle, and the storm-cover of a circle is installed in the inside of window, marginal position at storm-cover is provided with a hinge, be installed on the master window frame by hinge, evenly be provided with at least one aerofoil profile clip in other positions, described aerofoil profile clip is connected on the master window frame.
The asbestos cord of will preventing fires in technological improvement of the present utility model is used instead and is that fire proof seal bar, the fireproof performance of fire proof seal bar are 100 times of fire prevention asbestos cords, and the fireproof performance of whole fire window is promoted greatly, and the fire proof seal bar is aging almost not to have injury to the crewman.
Redesign on the utility model structure, improved safety factor greatly.

The specific embodiment
Embodiment one
Shown in Fig. 1-2, weld fixed fire-resistant porthole, comprise master window frame 1 and window seat 15, master window frame 1 is installed on the window seat 15, and joint face is provided with a circle fireproofing glue strip 14, described fireproofing glue strip 14 Embedded master window frame 1 inboards that are installed in.Master window frame 1 is designed to square, PLASTIC LAMINATED 2 and flame resistant glass 3 are installed on the master window frame, the marginal position of flame resistant glass 3 is PLASTIC LAMINATED 2, flame resistant glass 3 usefulness pressing plates 5 are fixed on the master window frame 1, junction in flame resistant glass 3 and master window frame 1, PLASTIC LAMINATED 2 is provided with refractory cotton 6, the side of waring oneself in front of a fire in flame resistant glass 3 junctions is provided with fire-resistant 8, and the back-fire side space is filled with caulking gum 7, and described flame resistant glass 3 is the individual layer implosion guard.
Embodiment two
As shown in Figure 3-4, master window frame 1 is designed to circle, and the storm-cover 10 of a circle is installed in the inside of window, one hinge 11 is set till the edge of storm-cover 10, be installed on the master window frame 1 by hinge 11, evenly be provided with at least one aerofoil profile clip 12 in other positions, described aerofoil profile clip 12 is connected on the master window frame 1.
The asbestos cord of will preventing fires in technological improvement of the present utility model is used instead and is that fire proof seal bar, the fireproof performance of fire proof seal bar are 100 times of fire prevention asbestos cords, and the fireproof performance of whole fire window is promoted greatly, and the fire proof seal bar is aging almost not to have injury to the crewman.
Redesign on the utility model structure, improved safety factor greatly.
