The casement window adopted by the utility model is provided with a window frame, a window sash is arranged in the window frame, one side of the window sash is connected with the window frame through a spring hinge, and the other side of the window sash is connected through a fusible bolt. The device has simple structure and convenient installation. And can open the flat-open window automatically when the conflagration breaks out, in time dispel the heat and discharge fume, can regard as the daylighting window normal use when not breaking out the conflagration.
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 casement window for a top side wall of a staircase.
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, and a manual opening device is arranged at a position which is 1.3-1.5 m away from the ground and is not convenient to open directly when the openable outer window is arranged at a high position. The prior art is as follows: the manual opening device is arranged at the position 1.3-1.5 m away from the ground, security personnel need to go to a staircase to manually open, and the openable outer window cannot be guaranteed to be opened in time at the initial stage of a fire.
SUMMERY OF THE UTILITY MODEL
Aiming at the defects, the utility model provides the heat-dissipation smoke-exhaust automatic opening casement window for the top side wall of the staircase.
The casement window used for solving the technical problem is provided with a window frame, a window sash is arranged in the window frame, one side of the window sash is connected with the window frame through a spring hinge, and the other side of the window sash is connected with the window frame through an fusible bolt.
Furthermore, be equipped with fixing base an and fixing base b in the fusible bolt, fixing base a sets up on the window frame, and fixing base b sets up on the casement, is equipped with the bolt pole in the fixing base and connects fixing base a and fixing base b.
Furthermore, the window frame and the window sash are both rectangular.
Further, the window frame is disposed on the top side wall.
Furthermore, the window sash and the window frame are made of high-temperature-resistant materials, and the bolt rod is made of fusible alloy materials.
Furthermore, the opening angle of the spring hinge is 80-90 degrees.
Furthermore, double-layer wired glass is arranged on the window sash.
The working process is as follows: a flat-open window is opened automatically to heat dissipation that is used for stair top side wall discharges fume, and when the conflagration breaing out, high temperature flue gas gathers stair top, and the temperature rose in the stair room above 70 ℃, and the bolt pole in the fusible bolt melts, and the flat-open window outwards stretches under the spring hinge effect, and then opens the flat-open window automatically to reach the effect of heat dissipation and discharge fume.
Has the advantages that: the device has simple structure and convenient installation. And can open the flat-open window automatically when the conflagration breaks out, in time dispel the heat and discharge fume, can regard as the daylighting window normal use when not breaking out the conflagration.
