The present invention relates to a system for preventing the spread of flooding of a building structure, and more particularly, by preventing water leakage caused by damage to water pipes and fire-fighting pipes in the common space of each building floor from flowing into the elevating facility space to prevent flooding of the elevating facilities. It relates to a flood prevention system for building structures that can prevent and prevent the spread of flood damage to other floors.

In general, in elevator hall spaces such as apartment houses or business facilities, sprinklers, wall fire hydrants, and toilets (including household toilets) are adjacent to the ceiling, so flooding occurs frequently due to pipe leakage.

In particular, in the case of an elevator installed in an apartment building, it is composed of a complicated electric control device and a mechanical device. When water flows in due to flooding, the damage is large and rainwater enters the lower or basement floors of the apartment house during the rainy season when there is a lot of rainfall. Since it is flooded by rainwater flowing into the elevator when it flows, countermeasures against such flooding are necessary.

Therefore, in the prior art, in order to prevent flooding of the elevator, a method of temporarily blocking rainwater by stacking sandbags in front of the boarding gate is used. There was a problem of flooding before sandbags were built when rainwater suddenly swelled by

On the other hand, as an example of a technology for a flood blocking device inside an elevator to prevent the above-mentioned flooding, Korean Patent Registration No. 10-0330285 is composed of a car and a counterweight for elevating each predetermined path of the hoistway, and a shallow depth dimension. The hoisting machine installed on the outer surface of the car, a top pulley that is rotatably mounted on the top of the hoistway, the axis of rotation is horizontally arranged, and one end is connected to the upper end of the hoistway to descend, and is wound around the pulley of the counterweight to rise. , It is wound on the top pulley, it descends and is wound on the winding machine, and the other end rises and rises, the main cable is connected to the upper part of the hoistway, the main part of the winding machine is formed and the rotation axis is arranged in the horizontal direction so that the main cable is wound, and the side of the car An elevator device having a repair means installed in the hoist and opening corresponding to the repair portion of the hoisting machine has been disclosed.

However, since the conventional flood blocking device described above is a technology for preventing only the inside of the elevator from being flooded from inside the elevator, there is a problem in that it is difficult to fundamentally block the water leakage flowing into the elevator facility space from the outside. There was a problem that could not prevent the spread of flood damage.

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

The flood diffusion prevention system for a building structure (hereinafter referred to as a 'water inundation diffusion prevention system') according to an embodiment of the present invention is installed in a multi-story building structure, and leaks caused by damage to water pipes and fire-fighting pipes in the common space for each floor of the building structure It is configured to prevent the inflow of water from being diffused into the elevating facility space, thereby preventing flooding of the elevating facility and preventing it from spreading to other spaces. Here, the elevating facility space, the elevating hall may be the main space, but of course, not only the elevating hall but also the stepped corridor space is included.

Referring to FIG. 1 , the flooding diffusion prevention system may include a drain module 100 , a flood control module 200 , and a blocking module 300 so that water can be flushed and drained.

The drainage module 100 may include a drainage channel 101 , a drainage trench 110 , a piping unit 120 , and a cartridge unit 130 .

First, the drain 101 is formed at a predetermined depth on the floor of the common space for each floor in the building structure, and serves as a passage through which water flows in (refer to FIG. 3 ) and drains the introduced water. The drainage conduit 101 may have a depth and a planar size according to the designed drainage amount.

The drain 101 may be formed on the lower floor of the elevator 10 spaced apart from the front to prevent water from flowing into the elevator 10 when flooding occurs, as shown.

However, this is a preferred embodiment, and the drainage channel 101 can be installed on the lower floor of the elevator hall space where flooding is expected, and the formation position can be variously changed according to the structure of the building structure and the position of the elevator. have.

The drainage trench 110 is installed on the upper portion of the drainage passage 101 to prevent a safety accident caused by the drainage passage 101 to shield the drainage passage 101, and the upper surface is configured to coincide with the lower floor surface. It is configured to prevent safety accidents caused by city height differences.

The drain trench 110 is provided with a plurality of drain holes 111 through which water flowing in a plate shape can be drained to the drain channel 101 .

In the drawings, the drain holes 111 are formed in the form of a long slit and are arranged in a line along a predetermined separation distance. This is a preferred embodiment to prevent inconvenience to pedestrians' walking or rotation of wheels such as carriers, as well as prevent foreign substances from entering the drainage channel as much as possible. Of course you can.

On the other hand, the drain trench 110 is formed in the shape of a plate in which the drain holes 111 are formed, as described above, to effectively prevent the inflow of foreign substances into the drain 101 as well as to secure the amount of drainage. However, this is an embodiment, and in addition to the above configuration, a known mesh type trench may be applied.

The drainage trench 110 may be formed to have a width of 140 mm to 160 mm and a depth of 90 mm to 110 mm, preferably 150 mm wide and 100 mm deep. This is in consideration of the amount of drainage and the walking and movement of pedestrians, and if the size is smaller than the set size, there may be a problem in the amount of drainage, and if it is formed larger than this, it may affect the walking and movement of pedestrians.

In the drawing, the drainage trench 110 is formed in one configuration from one side to the other side of the lower floor, but a plurality of them may be disposed adjacent to each other in an embodiment.

The pipe part 120 is connected to the drain 101 and serves to drain the water to the outside.

It is connected in communication with the other end and the other end may be configured to include a horizontal pipe 122 that communicates with the outside to discharge the water to the outside (see FIG. 3 ).

Here, it is preferable that the vertical tube 121 and the horizontal tube 122 have a diameter of 75 mm or more. This is because, in consideration of secondary flooding prevention, if the diameter is smaller than the above-mentioned diameter, drainage is not smooth and two-dimensional flooding may occur.

The riser pipe 121 and the horizontal pipe 122 may be configured in various ways in consideration of the location of the drainage channel 101, and detailed descriptions thereof will be omitted because the configuration of a known drainage pipe can be applied. .

The cartridge unit 130 is formed through the drainage trench 110 and is installed in a through hole 112 that is selectively shielded and opened to close the through hole 112, but when submersion occurs, the through hole ( 112 is selectively removed so as to be opened so that drainage is made through the through hole 112 of the drainage trench 110 . Here, a detailed description of the cartridge unit 130 will be described later.

Referring to FIG. 2 , the flood control module 200 may include a flood detection sensor 210 , a water supply shutoff valve 220 , a control unit 230 , and an alarm unit 240 . .

First, the submersion detection sensor 210 is installed in the drain module 100 to detect whether water is introduced or not, and when the inflow of water is detected, it transmits a submersion signal to the control unit 230 .

The water immersion sensor 210 is installed at a predetermined height spaced apart from the bottom surface of the drain 101 in the upper direction, and may be installed at one or a plurality of points along the longitudinal direction of the drain 101 .

The installation height of the flood detection sensor 210 is installed at a certain height from the bottom of the drain 101, not the bottom of the drain 101, so that it can be determined that flooding has occurred due to water leakage, not living water. it is preferable

Accordingly, the water immersion sensor 210 may be installed at a position spaced apart from the bottom surface of the drain 101 by 40 mm to 60 mm, and preferably installed at a height spaced apart by 50 mm. The water immersion sensor 210, a known water sensor may be applied, and a detailed configuration thereof will be omitted.

The water supply shutoff valve 220 is installed in the water supply line of the building structure and operates according to a control signal received from the control unit 230 to cut off the water supply.

The water supply shutoff valve 220 may be installed adjacent to the front of the water supply meter (water supply branch pipe) installed in the building structure to effectively block and control the water supply for each household.

The water supply shutoff valve 220, a known electromagnetic shutoff valve may be applied, and a detailed description thereof will be omitted.

The control unit 230 is configured to transmit the control signal to the water supply shutoff valve 220 so that water supply is cut off when a immersion signal is received from the immersion detection sensor 210 .

Also, when the submersion signal is received, the control unit 230 transmits a signal to activate the alarm unit 240 to notify the submersion state from the outside.

The control unit 230 may be installed on the computer terminal of the management office of the building structure and configured to control the water supply shutoff valve 220 in the management office, or through an application installed on the administrator's mobile terminal, etc. It is also possible to control the operation of the water supply shutoff valve (220).

The alarm unit 240 is operated by the alarm signal received from the control unit 230, and is installed in the interior space of the building structure including the management office, the elevator hall space, the stairs, and the management office. It serves as a warning of flooding.

The alarm unit 240 may display a flood warning on the computer terminal of the management office or include an alarm alarm that outputs an alarm lamp or an alarm sound that is turned on by the alarm signal. It can be applied in various ways as long as the configuration can be notified.

Hereinafter, the cartridge unit 130 will be described in detail.

First of all, leakage due to pipe breakage in building structures occurs very rarely, but leaks occur exceptionally. is quite large.

For this reason, in the present invention, the drain holes 111 and the through holes 112 and 112a are separately formed in the drain trenches 110a and 110b, respectively, and the through holes 112 and 112a are shielded through the cartridge unit 130 in normal times. By allowing only the drain hole 111 to pass through, and to improve the drainage effect by opening both the drain hole 111 and the through holes 112 and 112a when a water leak occurs, it is possible to prevent the spread of flood damage due to water leakage. .

Accordingly, looking at the cartridge unit 130 described above, the cartridge unit 130 is installed in the drainage trench 110a and is selectively removed when flooding occurs to increase the drainage flow rate of the drainage trench 110a. .

Referring to FIG. 3 , the cartridge unit 130 is installed in the through hole 112 penetrating through the drain trench 110a to shield the through hole 112 , but is removed when submersion occurs and passes through the through hole 112 . The hole 112 is opened, and the through hole 112 is opened when flooding occurs in this way to increase the drain flow rate of the drain trench 110a.

Here, the through hole 112 is formed between the drain holes 111 of the drain trench 110a as shown and may be formed in a rectangular shape, but this is an example of a formation location and shape, etc. can be variously changed according to the size of the drain trench 110a and the size and shape of the drain hole 111 .

Looking in detail with respect to the cartridge unit 130 , the cartridge unit 130 may be configured to include a cartridge frame 131 and a cartridge 132 .

First, the cartridge frame 131 is formed in a shape corresponding to the through hole 112 and is installed in the through hole 112 , and an accommodating space in which the cartridge 132 is accommodated is formed therein.

Here, the cartridge frame 131 is configured such that the upper and lower portions of the receiving space are penetrated to have a vertical tubular frame structure, so that when the cartridge 132 is removed, the receiving space communicates with the drain 101 . .

The cartridge frame 131 may be detachably installed in the through hole 112 to facilitate replacement and maintenance of the cartridge 132 .

Here, when the cartridge 132 is removed and the receiving space is formed through the cartridge frame 131 , the user can attach and detach the cartridge frame 131 through the through hole 112 .

Accordingly, the cartridge unit 130 is configured to prevent theft, etc. because it is difficult to separate the cartridge 132 from the through hole 112 when the cartridge 132 is inserted into the cartridge frame 131 in normal times, and flooding occurs. When the cartridge 132 is removed, it is configured so that the user can easily separate it through the through-formed receiving space.

That is, the cartridge unit 130 is configured to prevent theft because it is usually difficult to separate, and is configured to be easily separated when replacement of the cartridge 132 is required after submersion.

Next, the cartridge 132 will be described.

The cartridge 132 is accommodated in the accommodating space, and is configured to react with water and selectively remove when submersion occurs.

Specifically, the cartridge 132 may be formed of a water-soluble material soluble in water, and may be configured to be removed by dissolving in the water when submersion occurs.

On the other hand, the cartridge 132, as described above, is formed of a material that dissolves in water so that it can be selectively removed when submersion occurs, and furthermore, when dissolved in water so as not to affect drainage, the occurrence of foreign substances should be small, and at room temperature It is preferable to be formed of a material having a high hardness (strength) in a solid (hardened) state in a size set in a solid (hardened) state so that the phase change is small and the shape can be maintained even in the horizontal or downward external force.

To this end, the cartridge 132 is not only soluble in water, but also does not generate foreign substances when dissolved in a natural material, and in a solid state, a material of a sugar compound or a chlorinated compound having a set strength can be applied.

First, when the sugar compound material is applied, the cartridge 132 is manufactured by processing the extract extracted from natural sugar raw materials including sugar cane, sugar beet, sugar maple, and sugar corn.

At this time, the method of processing the sugar raw material essence may be processed in various ways so as to have the shape and desired strength of the cartridge 132 described above.

As an embodiment of this processing method, the cartridge 132 may be compressed to have a set shape and strength after the sugar raw material essence is processed into a powder form. Alternatively, in another embodiment, the cartridge 132 may be processed to have a set shape and strength by processing after adding an additive to the sugar raw material essence.

On the other hand, examples of the above-mentioned sugar compound may be variously applied, such as sugar or candy.

Next, when the chlorinated compound material is applied, the cartridge 132 may be manufactured by processing the chlorinated compound to have the above-described cartridge 132 shape and strength. Here, as the chloride-based compound, a chloride-based compound such as sodium chloride or calcium chloride may be applied.

According to the above, the cartridge 132 can be made of a sugar compound material or a chlorinated compound material that is soluble in water and has a set strength, and among them, when formed of a sugar compound material, it is environmentally friendly and corrosion-resistant because it is harmless to the environment. It has properties that do not cause it, but the rate of dissolution in water may be somewhat slow.

On the other hand, when formed of a chlorinated compound material, the cartridge 132 has excellent water solubility and a high dissolution rate, so rapid drainage can be made, but since it causes corrosion, when using a chlorinated compound material, the material of the drain line must be changed. If a non-corrosive metal is applied, or if a corrosive drain line is already formed, it is necessary to consider using a chlorinated compound material.

Furthermore, the cartridge 132 may be composed of a sugar compound or a chloride-based compound as described above, but in a preferred embodiment, it may be applied by processing a material such as water-soluble starch (starch). It goes without saying that a material such as a water-soluble resin, a water-soluble polymer compound, or a water-soluble pulp can be applied.

4 is a view showing a change in the state of the cartridge unit 130 when the submergence occurs.

Referring to the drawings, first, as described above, the cartridge 132 is configured to be removed by dissolving in water flowing in when submersion occurs.

Accordingly, in the case of the normal case shown in (a) of Figure 4, the cartridge unit 130, the cartridge 132 is inserted into the cartridge frame 131 as it is, and thus the installed through hole 112 is shielded. are doing

Accordingly, normally, the drain module 100 is configured such that only the drain hole 111 of the drain trench 110a communicates with the drain 101 to prevent foreign substances from being introduced into the drain 101 as much as possible.

On the other hand, when immersion occurs in the above state and water flows in, the cartridge unit 130 is removed by dissolving the cartridge 132 by the inflowing water as shown in (b) of FIG. Accordingly, as the receiving space is exposed as it is, the through hole 112 is opened to communicate with the drain 101 .

Therefore, the drainage module 100 is configured such that only the drain hole 111 is normally opened by allowing the cartridge 132 to be selectively removed when flooding occurs, and when flooding occurs, not only the drain hole 111 but also the through hole ( 112) can also be opened to increase the amount of drainage, thereby improving the drainage effect.

Meanwhile, the cartridge units 130a and 130b may be configured according to various embodiments.

First, the cartridge unit (130a) may be composed of a cartridge frame (131a) of various shapes.

Referring to FIG. 5 , the cartridge frame 131a may be formed such that the size of the flat cross-sectional area decreases from the upper surface to the lower surface.

Accordingly, the cartridge unit (130a), the cartridge frame (131a) does not slide downward from the through hole (112a) even if the external force in the horizontal direction or downward due to the user's walking or the dragging of the carrier is applied. It is possible to maintain the installation position for the hole (112a).

Here, the upper surface of the cartridge frame (131a) is installed in the through hole (112a) to form the same surface as the installation floor so as not to affect pedestrians walking.

And the through hole 112a is formed in a shape and size corresponding to the cartridge frame 131a according to the shape of the cartridge frame 131a, and the size of the flat cross-sectional area decreases from the upper surface to the lower surface. . In this case, an unexplained reference numeral 110b denotes a drainage trench.

On the other hand, the cartridge frame (131a) may be formed to have the same thickness as shown, so that the accommodating space therein is formed to have a smaller flat cross-sectional area from the upper surface to the lower surface. However, this is an embodiment of the cartridge frame (131a), of course, it is possible to form various shapes of the receiving space, and accordingly, the shape of the cartridge (132a) can also be changed.

According to the above-described embodiment, the cartridge unit 130a is configured such that the size of the flat cross-sectional area becomes smaller as the shape of the cartridge frame 131a goes from the upper surface to the lower surface. It is possible to maintain the installation position without the need to walk, and it is possible to prevent the inconvenience of walking and the trapping of foreign substances due to the height difference with the installation floor.

Next, the cartridge unit (130b), the shape of the cartridge (132b) can be configured in various ways.

Referring to FIG. 6 , the cartridge 132b may be formed such that the vertical thickness of the set portion is reduced.

Specifically, the cartridge 132b is preferably formed in a spherical surface having a relatively thin central section thickness so that the thickness in the vertical direction becomes thinner from the edge to the center as shown.

This is to minimize the amount of cartridge material and form the lower surface in an arcuate shape to have a structure with improved resistance to the external force of the upper part, and a penetrating portion is first formed in the center of the cartridge 132, which has a relatively thin thickness at the time of dissolution. , because the drain passage is formed along the formed penetrating portion, so that the through-portion can be rapidly expanded by the flow rate of the drained fluid (water).

On the other hand, the cartridge unit described above, as described above, the cartridge is dissolved in water so that the penetrating portion can be automatically generated, but it is of course that an administrator can manually remove it.

According to the above description, the drain module 100 separates the drain hole 111 and the through hole 112 and 112a in the drain trenches 110a and 110b, respectively, so that only the drain hole 111 is normally formed. The through-hole (112112a) is penetrated and shielded to prevent foreign substances from entering the drain 101, and when a water leak occurs, the cartridges 132, 132a, 132b are dissolved in water and automatically removed, thereby draining the drain hole 111. and through-holes 112 and 112a are penetrated, so that when water leakage occurs, drainage efficiency can be quickly improved.

Hereinafter, the blocking module 300 will be described in detail.

Referring to FIG. 7 , the blocking module 300 is installed in front of the opening/closing door 30 of the elevator installed in the building structure to prevent water from flowing into the elevator when flooding occurs, and is installed from the lower floor. It is raised to a set height and configured to block the inflow of water.

Specifically, as shown in FIG. 8 , the blocking module 300 is mechanically operated in conjunction with the opening/closing door 30 of the elevator. and is descended when the opening/closing door 30 is opened to open the front of the elevator.

In addition, the blocking module 300 is installed in the frame set 20 of the elevator without changing the structure of the building structure, so that it can be easily applied to other building structures.

Referring to FIG. 9 , the blocking module 300 may include a blocking member 310 , an elevating wire 320 , and a wire driving unit 330 .

The blocking member 310 is installed in front of the opening/closing door 30 to ascend and descend, and serves to open or shield the front lower portion of the opening/closing door 30 according to the elevation.

The blocking member 310 is configured to shield water from flowing into the elevator by installing both sides of the blocking member 310 up to both side wall surfaces of the elevator entrance as shown.
