Description
Technical Field
The utility model belongs to the technical field of fire-fighting engineering, and particularly relates to a heat-dissipation smoke-discharging automatic opening double-sash casement window for a staircase roof.
Background
According to article 3.2.1 of technical Standard of building Smoke protection and Smoke evacuation systems (GB 51251-2017): the area of the highest part of the closed stairway and the smoke-proof stairway adopting the natural ventilation mode is not less than 1.0m2The openable outer window or opening; when the building height is more than 10m, the total area of every 5 floors on the outer wall of the staircase is not less than 2.0m2And no more than 3 layers are disposed apart. Article 3.2.4 specifies: the openable outer window is convenient to open directly, can be opened when being arranged at a high position and is inconvenient to open directly, and the outer window is provided with a manual opening device at a position 1.3-1.5 m away from the ground. The opening of the outer window needs manual opening, and sometimes the phenomenon of unsmooth opening exists.
SUMMERY OF THE UTILITY MODEL
Aiming at the defects, the utility model provides the heat-dissipation smoke-exhaust automatic-opening double-sash casement window for the roof of the staircase, and the casement window can be automatically opened, so that the time for safely evacuating people is increased, the casualties are reduced, and the working strength of fire fighters is also reduced.
The device for solving the technical problem is provided with a window frame, wherein the window frame is arranged on a roof, a window sash is arranged in the window frame, and the window sash is connected with the window frame through a hinge; the window sashes are connected through fusible bolts.
Furthermore, the window frame is rectangular, two parallel edges of the window frame are provided with hinges, and the hinges are connected with the window sashes to enable the window sashes to be opened.
Furthermore, be equipped with 2 nearly word form fixing bases in the fusible bolt, 2 fixing bases pass through the fix with screw respectively on two casement, and the bolt pole passes the space realization casement fixed between fixing base and the casement.
Furthermore, the bolt rod is made of fusible alloy, and the window sash and the window frame are made of high-temperature-resistant materials.
Furthermore, double-layer wired glass is arranged in the middle of the window sash.
Furthermore, the double-sash casement window adopts a rectangular window.
The working process is as follows: a two fan flat-open windows is opened automatically in heat dissipation that is used for staircase roofing is discharged fume, and when the conflagration breaing out, high temperature flue gas gathers the staircase top, and the temperature rose in the staircase more than 70 ℃, and the bolt pole in the fusible bolt melts, and two fan flat-open windows open downwards under the action of gravity, and then reach the purpose of automatically opening two fan flat-open windows to reach the effect that the heat dissipation was discharged fume, increased personnel's safe evacuation time, reducible casualties.
Has the advantages that: the utility model does not need the fire fighter to go to the staircase and manually open, and ensures that the openable outer window is opened in time at the initial stage of fire. The fire control safety is improved, the time for safely evacuating the personnel is increased, the casualties are reduced, and the working strength of the fire fighters is also reduced. Meanwhile, the utility model has the advantages of simple structure, convenient installation, obvious effects of heat dissipation and smoke exhaust in time, normal use as a lighting window when no fire occurs, and wide application prospect.
