Description

Fire sprinkler system for apartment buildings

The present invention relates to a fire-fighting sprinkler system for apartment buildings in the field of firefighting technology, and in particular, an apartment house with an improved structure to enable effective initial fire extinguishing by installing a sprinkler member on the ceiling surface at a location avoiding the kitchen hood above the kitchen gas stand. It relates to a fire sprinkler system for a building.

In general, extinguishing fires occurring in buildings can be divided into extinguishing by fire extinguishers, extinguishing using fire hydrants, extinguishing by fire trucks and firefighters, and extinguishing by sprinkler devices.

Fire extinguishing by fire extinguisher and fire extinguishing by fire hydrant have the advantage that when a fire occurs in a building, the occupant uses a fire extinguisher or hydrant to extinguish a fire, and it is effective for early extinguishing. If you cannot use it, it becomes useless.

Firefighting by fire trucks and firefighters is difficult in the initial stage as it takes the time it takes for fire engines and firefighters to go to the scene of a fire after a fire occurs and a fire report is received.

On the other hand, each fire brigade attaches great importance to extinguishing the fire in the early stages, and is doing everything possible to extinguish the fire within 5 to 10 minutes, the so-called golden time of fire. However, they are dispatched due to traffic conditions or illegal parking in alleyways. The time required for it is getting longer.

As shown in FIG. 1, the fire sprinkler device of a conventional building is connected to a water storage tank 1 for fire extinguishing, and a primary pipe 2 connected to the water storage tank 1 and including a rising pipe installed in a pipe duct, and the primary It includes a secondary pipe (4) connected to the pipe (2) through an on/off valve (3) and installed in the ceiling, and a sprinkler head (5) installed in the secondary pipe (4) and exposed from the ceiling, The pipe (2) has a structure in which a pressure pump (6) for pumping water in the water storage tank (1) and a pressure tank (7) are installed.

In the fire sprinkler device of such a building, when a fire is detected by a fire detector, fire-fighting water is supplied to the first pipe (2) and filled, and the on/off valve (3) is opened to supply and fill the second pipe (4) with fire-fighting water. However, since the watering is performed only after the fuse (not shown) provided in the sprinkler head 5 melts and falls out when the temperature reaches 100° C. or higher, when a fire occurs in the gas stove, the initial extinguishment is not performed. There is a problem with the spread of fire.

In addition, the exhaust hood installed on the upper part of the gas range is a part where oil components generated during the cooking process are attached and are likely to spread rapidly through the exhaust duct when a fire is ignited. Fire extinguishing water sprayed from a conventional sprinkler head There is a problem in that it cannot prevent the spread of fire because it is not sprayed to the exhaust hood.

In addition, in the case of the existing sprinkler head, the risk of leakage was high in some cases because fire extinguishing water was kept full in the pipe.

Recently, a system for supplying extinguishing water only when a fire occurs in a state in which the supply of extinguishing water is cut off has been disclosed, but this has a disadvantage in that it cannot quickly respond to a fire.

3 is an exemplary cross-sectional view of a sprinkler member according to the present invention.
4 is a piping diagram constituting a sprinkler system according to the present invention.
5 is an exemplary view of a water leak detector constituting a sprinkler system according to the present invention.

Hereinafter, preferred embodiments according to the present invention will be described in more detail with reference to the accompanying drawings.

The fire sprinkler system of the apartment building according to the present invention, as shown in FIG. 2, is a sink 10 equipped with a sink 11 in a space partitioned by a front wall (W1) and a side wall (W2), and a gas stove ( 21) is provided with a gas station 20 on which is seated, an exhaust hood 30 is provided on the upper portion of the gas station 20, and is applied to a kitchen equipped with a kitchen faucet 100 installed on the front wall W1. .

In addition, the sprinkler member 200 as shown in FIGS. 3 and 4 is installed on the kitchen ceiling surface that does not interfere with the exhaust hood 30 .

The sprinkler member 200 is fixed to the fire extinguishing water pipe 300 (refer to FIG. 4) and radially sprays around the sink 10 and the gas tank 20 at the initial stage of a fire to increase the initial fire extinguishing ability.

More specifically, the sprinkler member 200 includes a fastening end 210 assembled to the fire extinguishing water pipe 300 .

The fastening end 210 is formed of a tubular body protruding from the upper end of the member body 220, and the member body 220 is a bar type, which is easy to understand when viewed as a kind of trophy handle.

That is, the member body 220 is not a cylindrical member with an empty inside, but an open state in all directions, and the '⊂'-shaped member and the '⊃'-shaped member are arranged symmetrically with each other, and the upper end is tubular, respectively. It is integrally fixed to the outer circumferential surface of the chain fastening end 210 , and the lower ends are each integrally fixed to the outer circumferential surface of the tubular body fixing end 230 .

In addition, a fixing bolt 240 is fastened to the fixing end 230 , and a bearing is fixed to the lower end of the fixing bolt 240 so that the rotating disk 250 can rotate in place.

At this time, the rotating disk 250 has a drain hole 252 formed therein, and is configured to generate a rotational force by interference when the fire extinguishing water falls and drips.

That is, a part of the falling fire fighting water collides with the upper surface of the rotating disk 250 , and a part flows into the drain hole 252 and flows, causing a flow velocity difference to rotate the rotating disk 250 .

Therefore, when fire extinguishing water falls, the fire extinguishing water is discharged while being radially dispersed along the rotation radius of the rotating disk 250 to widen the initial suppression radius.

In particular, for smooth rotation of the rotary disk 250, a ball groove 254 of a certain depth in the circumferential direction is concave in a 'V' shape on the lower end surface of the rotary disk 250 .

Then, the rolling ball 256 is seated in the ball groove 254 , and the rolling ball 256 is supported by the ball support plate 258 .

In addition, the ball support plate 258 is fastened to the center of the lower end surface of the fixing bolt 240 by the fastening bolt 260 .

In addition, a rupture hole 270 is interposed between the lower end of the fixing bolt 240 and the fastening end 210 , and in particular, the upper end of the rupture hole 270 is partially inserted into the lower end of the fastening end 210 . A stopper 272 for sealing the state is provided.

At this time, the stopper 272 is integrally formed on the upper end of the rupture hole 270 , and an O-ring (reference numeral omitted) is fitted around the stopper 272, and the O-ring is a polyurethane resin in order to maximize the sealing effect. 30% by weight, 10% by weight of rosin, 10% by weight of xanthan gum and the remaining silicone resin are molded into the composition is preferably used.

Therefore, when the rupture hole 270 is placed in a state where the stopper 272 is inserted and sealed with an O-ring, and the rupture hole 270 is pushed up with a strong force by tightening the fixing bolt 240 in that state, the stopper 272 is tightly closed. Since the lower end of the fastening end 210 is sealed while sealing the fastening end 210, even if the fastening end 210 is filled with fire extinguishing water, it is not easily leaked unless the rupture hole 270 is ruptured.

Here, the rupture hole 270 is a kind of metallic fuse, and is configured to melt and fall off when a certain temperature is raised due to a fire.

Therefore, the sealing force by the stopper 272 is very good because it endures with a very strong force in normal times.

On the other hand, in the present invention, as in the example of FIG. 4 , the fire extinguishing pipe 300 to which the fastening end 210 is assembled is divided into a pipe part 302 and a pipe end 304 , and is flange-fixed to form an integral body. The fastening end 210 is installed on the pipe end 304 while being configured to achieve this.

And, the opening/closing valve 310 is rotatably built in the pipe part 302 about the shaft 312 .

In addition, a wiring 314 is fixed to the center of one side of the on-off valve 310 .

In addition, a plurality of, preferably four, protrusions 320 are installed at regular intervals in the circumferential direction of the pipe portion 302 on the surface side of the opening/closing valve 310 on which the wiring 314 is formed. .

At this time, the protrusion body 320 is a housing 322 screwed to the outer circumferential surface of the pipe part 302, and the protrusion is inserted into the housing 322 and assembled to be exposed to the inner diameter of the pipe part 302 for a certain length. 324, a compression spring 326 for pulling and compressing the protrusion 324, and a cover 328 screwed to the housing 322 to fix the compression spring 326.

In addition, one end of the wire (W) is fixed to the end of the protrusion 324, and the other end of the wire (W) is pulled through the wiring 314 to expose the protrusion 324 to the inside of the tube. It is fixed to the stopper 272 sealed to the fastening end 210 .

Therefore, when the rupture hole 270 is melted and ruptured by heat generated during a fire, since the stopper 272 is also made of the same material, it melts at the same time and the binding force of the wire W is released.

Then, the wire W is released, and while the compression spring 326 of the protrusion body 320 is compressed, the protrusion 324 is drawn in to release the stopping function of the opening/closing valve 310 .

Accordingly, the opening/closing valve 310 is opened while being rotated with respect to the shaft 312 due to the hydraulic pressure of the fire extinguishing water, which causes the fire water to be supplied to the fastening end 210 to be rapidly sprayed and discharged.

On the other hand, in the present invention, as in the example of FIG. 5 , when water leaks due to a decrease in the sealing force of the on/off valve 310 and the fire extinguishing water flows to the pipe end 304 , in order to solve the problem that the load of the stopper 272 is increased. A water leak detector 400 is further installed on the lower surface of the pipe end 304 so that it can be known in advance whether there is a leak.

At this time, the water leak detector 400 includes a sensor block 420 mounted with a wired transmitter 410 that transmits a signal to a controller (not shown) upon detecting a water leak.

And, the sensor block 420 further includes a rod-shaped elastic guide 440 formed integrally with the block ring 430, and a battery is built-in inside the sensor block 420, the battery is a water detection sensor (to be described later) 480) is energized only when water is sensed, and only then, the wired transmitter 410 operates, and since the current required for transmission is only a very small current, the battery can be used almost semi-permanently.

In addition, a tangible spring 450 is fitted to the elastic guide 440 , and the tip of the tangential spring 450 is grounded to the head of the detection device 460 .

In addition, the detection tool 460 penetrates through the fixing guide 470 having a thread on the outer circumferential surface and is fitted with a pointed tip exposed, and a water detection sensor 480 is installed at the tip to leak into the pipe end 304 and flow. It is configured to detect water.

Therefore, when a leak is detected, the location can be accurately identified, and a large-scale accident can be prevented in advance by responding immediately.

Here, at one end of the fixing guide 470, a cylindrically hollow housing (HAG) is integrally formed, and in the housing (HAG), the above-described detection port 460, tanji spring 450, and elastic guide are formed. (440) is built-in, the block ring 430 is screwed.

Therefore, the tanji spring 450 elastically pushes the detection port 460 to induce the water detection sensor 480 to accurately maintain the exposed state inside the pipe end 460, thereby guiding stable detection. .

Accordingly, when a leak is detected, the controller can immediately check it, and the facility manager or resident can take action according to the alarm issued by the controller, thereby preventing the spread of a major accident.
