Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

The natural smoke exhausting window structure of shared front chamber in high-rise residence as shown in figure 1 includes: a staircase room 10, an elevator room 20, a shared front room 30 and a bay window 40;

the stairwell 10 is arranged adjacent to the elevator car 20 at the same end, and both side walls of the shared front room 30 are respectively communicated with the entrances of the stairwell 10 and the elevator car 20; the bay window 40 is disposed opposite to the entrance of the elevator car 20, and the window is disposed to protrude from the sidewall of the shared front room 30, and the bay window 40 has an inward opening window structure.

In the above embodiment, the arrangement of the bay window 40 is adopted, the design area of the building is not increased, the effective area for opening the natural smoke exhaust window is ensured through the structure of the inward casement window, and meanwhile, the ordinary passage of the shared front room and the fire rescue in case of fire are not influenced. The problem that the opening effective area of the natural smoke exhaust window cannot be guaranteed in the prior art is solved, and due to the adoption of the mode of the convex window 40, the opening and closing of the window sash has no influence on the space in the shared front chamber 30, so that the normal passing of the shared front chamber and the fire disaster are not influenced, and the fire rescue work is not caused.

In order not to affect the sunshine on the north side by the projected outer wall portion of the bay window 40, the bay window 40 is provided in the east or west direction of the shared front room 30. By adopting the arrangement in the east-west direction, the influence on the daylighting rate of the building on the north side is reduced.

As a preferred example of the above embodiment, as shown in fig. 4, the sash of the bay window 40 is configured to be opened inward. It should be noted here that the bay window 40 has an outward projection of not more than 1m to facilitate the opening and closing operation of the window sash by a person in the shared front compartment 30.

Further, the sash opening angle of the bay window 40 is not less than 70 degrees. The opening angle of the window sash determines the effective window opening area, so that the window sash opening angle of the bay window is preferably 70 degrees in order to reasonably utilize the bay window and facilitate the operation.

Due to the large opening effective area of the window sash, for safety reasons, as shown in fig. 2, a guard rail 41 is arranged inside the bay window 40.

Specifically, as shown in fig. 3, a base 401 is disposed on the upper surface of the bottom of the bay window 40, and the guardrail 41 includes a base 411, a rail 412, and a vertical rail 413;

the rail 412 and the vertical rail 413 enclose a rectangular rail structure, the base 411 is fixed at the bottom of the rectangular rail structure and detachably connected with the base 401, two ends of the rail 412 are screwed with fastening seats 4121, and the distance between the fastening seats 4121 and two ends of the rail 412 is changed through rotation.

When specifically installing, align the base 411 of guardrail bar 41 with base 401 on the bottom upper surface of bay window 40 earlier, be connected base 411 with base 401 through the fastener, the both sides of horizontal bar 412 are close to the both sides wall of bay window 40 this moment, through the mode of rotatory fastening seat 4121, make fastening seat 4121 move towards the direction that is close to the side wall, the meshing that finally passes through between the screw thread makes fastening seat 4121 closely laminate with the side wall, thereby reach the effect with guardrail bar 41 monolithic stationary in both sides, this kind of fixed mode has improved the installation rate, but also demountable installation's setting, the maintenance of guardrail bar 41 of also being convenient for, do not produce the harm to the wall body.

In the embodiment of the present invention, the height of the guardrail bar 41 is 80-130 mm. The height setting of guardrail bar 41 should not produce any shelter to operating personnel's arm when opening or closing the casement to open the casement in the very first time, win rescue time.

Because the smoke has a certain expansion pressure when a fire occurs, the pressure emitted from the inside may close the opened window sash again, in order to prevent the window sash from being closed by itself, as shown in fig. 3 and 4, the guard rail 41 is further provided with a window sash fixing seat 414, the window sash fixing seat 414 is provided with a locking hole, and when the window sash is opened to a maximum angle, the window sash corresponds to the locking hole to fix the opening angle of the window sash. It should be pointed out here that casement fixing base 414 sets up on the horizontal bar 412 of guardrail bar 41 top, and its position sets up when the casement is opened to the maximum angle (this utility model discloses the embodiment is 70 °), and the lockhole position corresponds with the spring bolt on the casement, after the casement is opened, make the spring bolt on the casement enter into in the lockhole of casement fixing base 414 through rotatory locking handle, thereby realize opening the fixed of angle to the casement, even when there is pressure in inside, still can keep opening of casement, the smoke exhaust effect of cigarette window has been guaranteed, be favorable to the control of conflagration and the going on of rescue work.

It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention. The scope of the invention is defined by the appended claims and equivalents thereof.
