Description

The utility model relates to building structures, namely, to devices for protecting window openings and can be used, including, and to ensure the possibility of emergency evacuation of people from buildings with high floors.

Rescue and evacuation measures during fires in high-rise buildings could be much more effective if building structures, in particular window openings as one of the ways of spontaneous, hopeless evacuation, would be performed as an element that facilitates escape, escape from fire.

The proposed utility model aims to offer constructive solutions that expand the evacuation capabilities of the classic elements of building structures.

A device for protecting a window opening (Patent RU 2214494 C2, class ЕВВ 9/02), consisting of a sectional grill installed in the lower part on horizontal hinges, and in the upper part, on latches with the possibility of their unlocking, was selected as a prototype.

The disadvantage of this design is its lack of functional properties, namely, the provision of the possibility of evacuation only down to 2-3 floors, the inability to create conditions for accommodating people in anticipation of outside help in relatively “comfortable”, tolerable conditions.

The problem is solved by placing evacuated people on a protective lattice in a horizontal position, for which it is proposed to connect the upper edge of the lattice with cables to the building structure of the building.

The grate, held by ropes in a horizontal position, allows people fleeing from the effects of damaging fire factors to wait for outside help or to go down independently using vertical evacuation means, for which it is proposed to install a container for storing them in the upper part of the grate and equip the grate with attachment points .

In addition, to prevent people from falling from the grill between the cables and building structures, two rails are installed on each of the sides and one along the far side of the grill.

The essence of the utility model is illustrated by drawings (Fig.1-3).

Sectional grill 3 is installed in the building structure 1 on horizontal hinges 4 and is fixed in a vertical position by latches 7, with the possibility of disclosure.

The device includes two cables 5 in their design, each of which is attached on hinges 6 to the building structure 1 and in the upper part of the grating on hinges 12. The length of the cables is selected based on the possibility of ensuring the horizontal position of the grating. To the cables 5 and the building structure 1 are mounted on hinges 13 enclosing rails 8 and 9. On the sides and the upper side of the devices are mounted attachment points 11 means of vertical evacuation of people. In the upper part of the device is a container 10 for storing vertical evacuation facilities.

In normal mode, the grill 3 is in a vertical position, leaning on the hinges 4 with the latches 7 closed. Vertical evacuation means are loaded into the container 10, cables 5 and rails 8, 9 are laid between the grill 3 and the window opening 2.

In the event of an extreme situation, the device is brought into a “working” state as follows.

The latches 7 are unlocked from the building and when the shutters of the window opening 2 are open, the lattice 3 is pushed out. The lattice 3, turning on hinges 4, “falls” to a horizontal position and is held by cables 5, while the rails 8 and 9 open, enclosing the lattice area.

Evacuated people fleeing from the fire can be placed on grate 3, waiting for rescuers, or after removing from the container 10 vertical evacuation facilities and installing them on attachment points 11 to leave the danger zone.

Thus, the implementation of improvements will allow you to turn the protective grill from the blocking unit into a device that allows you to carry out protective measures.
