Description WATERPROOF CEILING

Technical Field

[1] The present invention relates to a waterproof ceiling, and more particularly to a waterproof ceiling for preventing severe damage due to water leakage generated through the ceiling of a computer room, an electrical room, a precision equipment room, a bank data storage room, a high-priced medical equipment room or the like. Background Art

[2] A ceiling finishing material used in a building includes a plaster board, miton and the like. When water leakage is generated in the ceiling, it causes severe damage to main equipment (a server, precision equipment, electric equipment, medical equipment, an electric machine or the like) and a power system, thereby resulting in enormous property damage. The ceiling of the building is configured by a lightweight ceiling steel frame for regularly arranging and fixing a ceiling finishing material and T-bars, M-bars, T-H bars and the like for attaching the finishing material. The finishing material may be an aluminum ceiling plate, a plaster board, miton or the like.

[3] Water lines for cooling and heating, water lines for extinguishing equipment and the like are installed in the ceiling of the building. When water in the water lines in the ceiling at the same floor and an upper floor leaks out, it may cause severe damage to the equipment installed under the ceiling.

[4] For example, the flood accident occurred at the computer room on the fourth floor of the security corporation in 2000 due to the malfunction of the springcooler which is disposed on the sixth floor. At that time, damage equivalent to several tens of billions of won was generated and security services were interrupted. That is, it may cause severe damage to a computer server, computer data of the bank, a power system of the building, high-priced medical equipment, information serving as a main source in an information-oriented society, and a building function. Further, it also causes damage to the clients, members and consumers.

[5] In order to solve the above-mentioned problem, the water lines in the ceiling are removed and gas-type extinguishing equipment is installed for waterproofing. Further, a waterproofing process is performed on the upper floor. However, since the upper floor is not vacant in many cases, the waterproofing process cannot be performed. Even though the waterproofing process is performed, it is difficult to prevent water leakage generated in fan coil lines, an outlet box and other gaps. Further, even though there is a waterproof effect, since water is quickly and widely distributed on the floor, it is difficult to remove the distributed water.

[6] In order to solve the conventional problems, Utility Model Registration No. 264930 discloses an auxiliary mechanism for detecting water leakage in the ceiling. The structure of the conventional waterproofing ceiling includes a waterproof assembly in which a number of waterproof members are joined and connected to each other to waterproof the entire region of the ceiling, a hanger frame which fixes the waterproof assembly to the rear surface of the concrete while providing a specified installation space therebetween, and drain lines installed at a peripheral sidewall of the waterproof assembly to discharge leaking water. Further, the waterproofing ceiling structure includes water leakage sensors fixed to the waterproof assembly at specified intervals to generate electrical detection signals by detecting a specified amount of water, and an alarm part buried in the waterproof assembly to alarm a manager by sound based on the detection signals. Further, waterproofing auxiliary materials are stacked in piles to waterproof the ceiling.

[7] However, since the conventional waterproofing ceiling has a large weight by stacking the waterproofing auxiliary materials on the waterproof assembly, there are problems such as a difficulty in the construction and an increase in a construction cost.

[8] Further, in the above-mentioned structure, when excessive water leakage is generated in the ceiling, the ceiling may be inclined, cracked or collapsed due to the load exerted on the ceiling.

[9] As another technology, Korean Patent No. 10-0702847 discloses a double ceiling having a lightweight structure for waterproofing and absorbing vibration. The double ceiling requires the height corresponding to a double space for installation in the ceiling. Thus, it is impossible to apply the double ceiling to a place having no spatial margin.

Disclosure of Invention Technical Problem

[10] Therefore, the present invention has been made in view of the above problems, and it is an object of the present invention to provide a ceiling of a lightweight structure having a single inclined surface capable of quickly collecting leaking water and discharging the water to the outside to safely manage information serving as a main source in an information-oriented society and protect an electrical room of the building, high-priced equipment and the like, thereby preventing enormous property loss and ensuring safety of human life and property.

[11] It is another object of the present invention to provide a waterproof ceiling for preventing damage due to water leakage generated through the ceiling of a computer room, an electrical room, a precision equipment room, a bank data storage room, a high-priced medical equipment room or the like.

[12] It is yet another object of the present invention to provide a waterproof ceiling in a ceiling assembly formed by joining and connecting the rear surface of the concrete and hanger bolts for supporting the ceiling to finish and decorate the entire region of the ceiling.

Technical Solution

[13] In accordance with an aspect of the present invention, there is provided a waterproof ceiling comprising: carrying channels fixed by hangers and hanger bolts fixed to a rear surface of concrete, water drain module bars fixed and connected to the carrying channels by module bar hanger portions, and main water drain portions disposed diagonally to the water drain module bars; and waterproof ceiling panel portions having insertion protrusions which are formed downward to be inserted into insertion grooves disposed at opposite sides of the water drain module bars and coupling portions which are formed upward, wherein the waterproof ceiling panel portions are disposed between the water drain module bars arranged at specified intervals such that their lower portions are inserted into the water drain module bars and their upper portions are coupled to each other to assemble an entire region of the ceiling.

[14] Preferably, the water drain module bars include insertion grooves formed between outer walls with inwardly bent end portions and inner walls with inwardly bent end portions, water drain paths formed between the insertion grooves, galvalume plates engaged and coupled to the bent end portions of the inner walls at opposite sides, and wing portions formed at opposite sides of bottom surfaces of the water drain module bars such that finishing plates are inserted by the wing portions.

[15] Preferably, the water drain module bars form an inclined ceiling surface to smoothly drain water and have an inclined surface to collect leaking water.

Advantageous Effects

[16] As described above, the present invention has an excellent effect of protecting main equipment in a water leakage accident occurring in lines disposed in the ceiling and on the upper floor and preventing the accident. Further, the present invention has an effect of reducing loss cost by safely managing the information serving as a main source in an information-oriented society and preventing damage to main equipment such that water leakage in the building does not cause damage to high-priced equipment.

[17] Further, according to the present invention, the load exerted on the ceiling is minimized to reduce the load exerted on the building. The ceiling is configured to have a single structure instead of a double structure to ensure its applicability to a facility. Various materials such as incombustible materials and noncombustible materials can be used as finishing materials and structural materials to ensure safety even in a fire. Thus, the present invention is highly applicable to the waterproof industry.

[37] Further, the outer walls 10 are formed to be higher and the inner walls 20 are formed to be lower in the two-step structure such that water in the water drain paths does not leak through joint portions. The outer walls are engaged with the inner surfaces of the waterproof ceiling panel portions to prevent dropping water from being discharged through a gap. [38] Wing portions 30 are formed at opposite sides of the bottom surface of the water drain module bars such that finishing plates 240 are inserted by the wing portions 30.

[39] The wing portions 30 are configured to support the finishing plates 240 by inserting the finishing plates 240 by the wing portions 30. The finishing plates 240 are formed of an aluminum ceiling plate, a plaster board, miton, synthetic resin or the like.

[40] In a water drain module bar shown in FIG. 3 according to another embodiment of the present invention, protrusions 10-1 are formed at upper portions of the outer walls 10 and the inner walls 20 are disposed at inner sides of the outer walls 10, thereby forming insertion grooves 70 such that the waterproof ceiling panel portions 160 are connected by inserting them into the insertion grooves 70. That is, the outer walls and the inner walls are formed in a «y» shape.

[41] Engaging portions 20-2 are formed at the inner walls of the opposite sides to mount the galvalume plates 50.

[42] As shown in FIG. 4, the protrusion bars 90 are formed downward on the opposite side surfaces of the waterproof ceiling panel portions 160. The coupling portions 150 are formed upward on the waterproof ceiling panel portions 160 in the opposite direction to the protrusion bars 90. The coupling portions 150 are configured to have connection protrusions 100 and bent connection grooves 140 to couple the waterproof ceiling panel portions by engagement.

[43] The coupling portions disposed on the waterproof ceiling panel portions may include the connection protrusions which are formed on the opposite side surfaces. Further, the coupling portions may include the connection protrusion which is formed on one side surface and the connection groove which is formed on the other surface.

[44] In another embodiment of the present invention shown in FIG. 5, the coupling portions 150 disposed on the waterproof ceiling panel portions include connection protrusions 100, respectively, to be coupled by inserting the connection protrusions 100 into insertion moldings 140-1.

[45] As described above, the connection protrusions are in close contact and coupled by inserting the connection protrusions into the insertion moldings, thereby conveniently and firmly coupling them.

[46] The waterproof ceiling panel portions 160 may be formed of various materials such as PVC, polycarbonate and aluminum. Further, the waterproof ceiling panel portions 160 may be formed of the above materials with high waterproof materials coated thereon or a combination thereof.

[47] Air circulation ports are disposed on the side surfaces of the waterproof ceiling panel portions such that air circulates through the waterproof ceiling. The waterproof ceiling panel portions include the protrusion bars formed downward to be inserted into the insertion grooves of the water drain module bars and coupling portions formed upward. Further, baffle portions 170 having shade-shaped air discharge ports are disposed on the extended protrusion bars to prevent water in the ceiling from entering

therein while inside air circulates through side surfaces.

[48] As shown in FIG. 7, a waterproof auxiliary member having a waterproof structure is efficiently applied to prevent water leakage through wiring, lines and connectors.

[49] In the waterproof ceiling of the present invention shown in FIG. 6, detectors 200 are formed to detect whether there is an abnormality in the ceiling. In the structure of the detectors 200, a through hole is formed in the center of the waterproof ceiling panel portion and the surface of the through hole is formed to be protruded upward to prevent water from overflowing and being discharged through the through hole.

[50] Covers 180 are disposed to be coupled to the protruded detectors 200.

[51] The operation of the waterproof ceiling of the present invention having the above- described configuration is explained in detail.

[52] Lines such as a water drain line, a water supply line and a springcooler are arranged in the building. In order to minimize damage when water leakage is generated due to old lines or maintenance defects, the waterproof ceiling system according to the present invention is applied to the ceiling of a computer room, an electrical room, a precision equipment room, a bank data storage room or a high-priced medical equipment room which is a place where enormous damage is expected in case of water leakage.

[53] Small water drain paths, i.e. the water drain module bars 80 are arranged in multiple lines to quickly drain water and disperse the weight, thereby reducing the load of the ceiling. The water drain module bars are provided with the insertion grooves such that the waterproof ceiling panel portions are coupled by inserting them into the insertion grooves. The insertion grooves have a two-step structure in which there is a difference between the heights of the inner and outer walls to prevent water leakage. That is, a two-step water level difference is formed to prevent water leakage.

[54] The waterproof ceiling panel portions may be formed to be higher to form a space capable of inserting an electric light. Further, the baffle portions 170 are disposed to form an air passage of an air conditioner.

[55] Although the preferred embodiment of the present invention has been disclosed for illustrative purposes, those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the invention as disclosed in the accompanying claims.
