Abstract

The fire water supply system of a high-rise building, consisting of at least one gutter, the design of each of which includes a funnel, riser, upper and lower shut-off devices, floor-mounted distribution valves and a drain, characterized in that it has a water conduit connected to the risers by nozzles equipped with pipes control valves between the upper and lower locking devices and equipped with a receiving pipe with a coupling half.

Description

The utility model relates to fire fighting equipment, namely, to water supply devices, fire extinguishing liquid, compositions, to the sources of fires that occur in a high-rise building, structure.

Fires in high-rise buildings, structures, which usually include buildings, structures more than 75 meters high, or buildings above nine ground floors, usually lead to serious consequences and significant losses.

Conventional fire fighting equipment for extinguishing fires in high-rise buildings is not effective due to:

- The inability to supply regular fire fighting and rescue equipment on floors above the ninth;

- The inability to use traditional fire extinguishing systems due to normal power outages and shutting down fire pumps;

- The inability to use external fire extinguishing systems due to the occupation of the local area by cars of living (working) citizens and green spaces.

The purpose of the utility model is to substantiate a relatively simple, stable, low-cost system design that allows delivering water, fire extinguishing liquid to possible foci of combustion in a high-rise building.

As a prototype of the utility model, a system consisting of gutters (application No. 2012143830 dated 10/15/2012) was adopted, in which a water system and gutters to extinguish fires were used, a system of gutters that “pierced” a uniformly tall building from top to bottom and placed in accordance with requirements of conditions for the removal of precipitation from flat roofs of buildings.

Each drain consists of a funnel, riser, upper and lower shut-off devices, floor distribution valves and a drain pipe.

At the same time, risers and drain pipes can be placed in buildings in those places where liquid supply from the outside is impossible due to structural, technological or planning decisions.

This drawback can be eliminated by supplying (supplying) liquid to the risers through a water conduit having a structurally simple, free exit to the adjacent area, on which a receiving unit can be equipped and its connections with risers, through which liquid can be supplied to the floors.

Thus, the water conduit connected to the risers will allow to supply liquid to all areas floor by floor through the gutters “penetrating” the entire building.

Structurally, this solution is presented in the following form.

The figure (figure 1) shows the proposed fire water supply system of a high-rise building. The fire water supply system of a high-rise building (1) includes several drains, each of which has a funnel (2), a riser (3), upper (4) and lower (5) shut-off devices, floor distribution valves (6), drain pipe (7 ) To supply fluid to the risers, it is proposed to use the water conduit (8) in the system design, passing near the risers, with which it is connected by pipes (9). On the nozzles between the water pipe (8) and the riser (3), control valves (10) are installed that pass liquid from the water pipe (8) to the riser (3) and prevent the liquid from flowing from the riser (3) to the water pipe (8). To supply fluid to the water conduit, it is equipped with a receiving pipe (11) with a coupling half (12) that is carried outside the building structure of a high-rise building (1) at a site that allows the placement of a high-pressure pump station and water intake from an appropriate source.

The fire water supply system of a high-rise building is as follows.

In standby mode, the system elements are in the position:

- the upper (4) and lower (5) locking devices are open;

- floor-mounted distribution fittings (6) do not allow liquid to pass onto floors;

- control valves (9) are closed.

Precipitation drained from the roof of the building (1), through the funnel (2), riser (3), drain pipe (7), is discharged into the corresponding system or to the surface.

In the case of water supply to the floors, the elements of the system are transferred to the provisions:

- the upper (4) and lower (5) locking devices are closed;

- the control valves (10) open (open).

The fluid is supplied through the inlet pipe (11) and the coupling half (12) into the water conduit (8). Further, the liquid with the open control valve (10) through the pipe (9) is supplied to the corresponding riser (3) and through it through the floor distribution valves (6) to the place of use.

By changing the combination of Open-Closed commands of shut-off devices, control valves, and floor distribution equipment, it is possible to achieve fluid delivery from the inlet pipe through the water conduit to any places of the high-rise building programmed in advance.

Thus, the use in the fire water supply system of a high-rise building of a receiving branch pipe with a half-coupling, a water conduit, branch pipes with control valves makes it possible to deliver liquid from an external source to the riser risers and to the floors of a high-rise building.
