Description

Built-in Ceiling type Hot and Cold Distributor with Structure for Piping and Repairing easily}

The present invention relates to a ceiling-embedded distributor having a structure that can be easily coupled / disconnected when connecting pipes, and more particularly, an elbow is coupled to a flexible pipe at the time of pipe connection between a distribution pipe header and a flexible pipe of a ceiling-embedded distributor. Some of the flexible pipe joints of the pipe header are inclined at a predetermined angle with respect to the axial direction, and at the same time, the distribution pipe header provides a structure that can be rotated at a predetermined angle with respect to the axial direction. Cold and hot water pipes are bent in the horizontal direction to be joined to each other without direct coupling in the state of being 휜. It is easy to separate and prevents leakage caused by soft pipe damage due to grip ring eccentricity of soft pipe connection socket. By working without difficulty, the efficiency of hard work performed on the lower part of the ceiling is greatly improved, and the pipe with large diameter forms the soft pipe joint in the horizontal direction, thereby branching the cold and hot water pipes to the side to facilitate the pipe connection. It relates to a ceiling-embedded distributor having a pipe connection structure that can improve the structural strength of the ceiling concrete.

In general, when building or expanding residential spaces such as houses, apartments, officetels, hotels, etc., the cold and hot water pipes introduced from the outside are heated through a hot water boiler and installed in each room through a heating water distributor installed at the bottom of the sink, built-in cabinet, and dressing room. And to send the heating water to each demand for heating, such as the living room, the cold and hot water dispenser is provided to supply and use the cold and hot water to each demand destination, such as toilet, bathroom, boiler room, utility room, laundry room, auxiliary kitchen.

Here, the cold and hot water distributor is generally installed in the distributor box, the cold and hot water pipe is a double pipe structure in which the cold and hot water pipes are fitted in the inside of each customer in the inside of the protective corrugated pipe (Jabara-shaped soft pipe, Corrugated duct) curved outer surface Bound to the battleship or faucet connector to supply cold and hot water.

However, when the cold and hot water distributor is installed in the lower part of the sink, the built-in cabinet, the dressing room cabinet, the storage space inside the cabinet is reduced, and the installation position of the cold and hot water distributor is limited when the landfill is installed on the wall, and the front finish after installation. There were many aesthetic problems as the lid was exposed to the architectural finish. For this reason, the method of embedding a cold and hot water distributor box in the lower slab of the ceiling of the bathroom is widely adopted.

As shown in FIG. 1, the pipe connection structure of the ceiling-embedded cold / hot water distributor box 100 having a double pipe structure for supplying and distributing conventional hot and cold water includes a housing 100a, an upper lid 100b, and a lower lid 100c. Cold and hot water distribution pipe headers 101 and 201 are disposed up and down in the distributor box 100, and the distributor box 100 is embedded in the concrete of the lower slab of the toilet floor, and the through-holes on the right or left side of the enclosure are installed. The cold and hot water pipes 102 and 202 introduced are coupled to the soft pipe coupling parts 1011 and 2011 formed on the right or left side of the distribution pipe headers 101 and 201, respectively. In case of leakage of the joint coupling part of the ceiling, open the ceiling check hole (3a) of the toilet (3), loosen the fixing means of the lower lid (100c) of the ceiling-embedded cold / hot water distributor box (100) and open the lower lid (100c) to the ceiling-embedded cold / hot water distributor (100) narrow space inside Insert the hand into the joint and loosen the soft pipe connecting socket 32 of the distribution pipe header 101 and 201, and force the cold and hot water pipes 102 and 202 to the outside in the horizontal direction to pull and disassemble and repair them. In order to insert the pipes 102 and 202 in accordance with the soft pipe connecting socket 32, bend to one side by applying a force in the horizontal direction and insert the holes into the soft pipe connecting socket 32 of the header after the holes are aligned. (32) is to be tightened by tightening, the cold and hot water pipes (102, 202) in the horizontal direction, the outward force is bent and inserted into the hole in a state of being very difficult and difficult to insert, the cold, Cold and hot water pipes (102, 202) are bent and broken due to the operation of drawing or inserting the hot water pipes (102, 202) in a horizontal direction, with the force applied in the outward direction. Grip There is a problem in that the grip-ring damage caused by eccentric joint leak occurs often in (32a- see Fig. 3). As shown in FIG. 3, the soft pipe connection socket 32 tightly fixes the cold and hot water pipes 102 and 202, which are soft pipes inserted into the grip ring 32a, the washer 32b, and the O-ring 32c. It is a conventional technology that is widely used in the art as a socket to.

In addition, as shown in Figure 1, the conventional pipe construction method of the ceiling-filled hot and cold water distributor box 100 is fastened to the lower slab (2) of the toilet ceiling (3) when the lower lid (100c) is fastened during the initial piping construction It is fixed to the upper part and the distribution pipe headers 101 and 201 are arranged to overlap each other up and down inside the distributor box, and the cold and hot water pipes 102 and 202 of the double pipe structure through the lower slab 2 are through-holes on the side of the distributor box 100. Arranged in two rows up and down through the (100a1) and drawn in a zigzag form to the soft pipe coupling portion (1011, 2011) of the distribution pipe header (101,201) including the grip ring (32a), washer (32b) and O-ring (32c) After direct fitting, the upper lid 100b of the distributor box 100 is closed, and the lower slab (2) concrete is placed, and the lower slab (2) formwork of the ceiling (3) is dismantled and the cold and hot water piping in the household is completed, and then the water pressure If the inspection is to be carried out, if the upper and lower two rows in the interior of the distributor box 100 Soft pipe coupling portion of the distribution pipe header 201 for hot water installed on the lower side when the joint leakage of the cold water pipe 102 coupled to the soft pipe coupling portion 1011 of the cold water distribution pipe header 101 disposed in the bottom ( 2011) repair is possible only if all the hot water pipes 202 coupled are separated, and the hot water pipes 202 separated after the repair have to be recombined again. There was a problem that the overall maintenance cost is increased.

In addition, the pipe connection structure of the conventional ceiling-embedded cold and hot water distributor box, as shown in Figure 1 through the one side of the ceiling-embedded cold and hot water distributor box 100 to form a plurality of through holes in two rows and the outer surface is curved protective corrugated tube ( A bellows-shaped CD tube, Corrugated Duct) is coupled to the side of the distributor box 100, so that a large number of corrugated tubes are formed on one side when it is embedded in the concrete wall, so the space where concrete is not inserted is largely weakened the structural strength of the bathroom ceiling. There was a problem.

In order to improve such a problem, as shown in FIG. 2, in the applicant's prior patent application No. 2010-49677, the elbow coupling parts 1011 and 2011 of the cold and hot water distribution pipe headers 101 and 201 are lowered to thereby cool and hot water. The pipe connection structure has been disclosed to be coupled by pressing after inserting the elbow 30 coupled to the ends of the pipes (34, 35).

However, the recent pipe connection structure as shown in Figure 2 also elbow coupling portion 1011 of the distribution pipe header 101, 201 in a state in which the elbow (30) coupled cold, hot water pipe (34, 35) in a certain state 1021), the elbow coupling portion (1011, 1021) and elbow 30 of the distribution pipe header (101,201) and the elbow (30) must meet the elbow 30 to elbow 30 without exerting a lot of force to vertically meet exactly 1021 can be inserted.

In more detail, the cold and hot water pipes 34 and 35 inserted into the CD pipe are all wound on a large reel and are curved in an arc shape having a predetermined diameter rather than a straight shape. The elbow 30 is coupled to the ends of the cold and hot water pipes 34 and 35 that are bent in the hole of the elbow coupling portions 1011 and 1021 of the distribution pipe headers 101 and 201 fixed in the distributor box 100. It is inserted at the same time, but most of them do not fit well, so they are strongly inserted. In case of strong insertion, the surface of the cold and hot water pipes 34 and 35 connected to the elbow 30 and the soft pipe connection socket 32 may be wound by the grip ring 32a, or continuously coupled to the air. As a result of tension, the eccentricity of the grip ring 32a is generated as time passes on the surfaces of the cold and hot water pipes 34 and 35, causing leakage.

In addition, a plurality of cold and hot water pipes 34 and 35 connected to the elbow 30 from the cold and hot water distribution pipe headers 101 and 201 and penetrate the distributor box 100 to the ceiling slab concrete 2 are provided. There is a problem in that the flocking to one side weakens the structural strength of the concrete and the surface can be separated even in the impact of weak concrete.

In addition, most of the cold and hot water pipes 35 and 15 connected to the cold and hot water distribution pipe headers 101 and 201 are mainly used for branch pipes, and soft pipes having a diameter of 15 mm are used for cold and hot water distribution pipe headers 101 and 201. Cold and hot water supply pipes 36 for supplying cold and hot water are used in a 20 mm soft tube having a larger diameter (if a 15 mm soft tube is used, the supply flow will be insufficient). When connected to the same pipe connection structure as the cold and hot water pipe 35, there was a problem that the distributor box 100 becomes larger. The distributor box 100 is slightly larger, but as the hollow is generated inside the ceiling slab concrete 2, the structural strength is very weak and is a problem.

The present invention has been made to solve the conventional problems as described above, when connecting the elbow to the soft pipe when the pipe connection of the distribution pipe header and the flexible pipe of the ceiling-embedded distributor and a part of the soft pipe coupling portion of one distribution pipe header Is formed to be inclined at a predetermined angle with respect to the axial direction, and at the same time, the distribution pipe header is rotatable at a predetermined angle with respect to the axial direction. (35) is bent in the horizontal direction to directly insert into the up, down, left, right right direction using the elbow (30) without direct coupling in the 휜 state, by coupling / soft tube without excessive bending and pressure It is easy to separate and prevents leakage caused by soft pipe damage due to grip ring eccentricity of soft pipe connecting socket. The efficiency of the hard work carried out at the lower part is greatly improved, and large diameter pipes are formed by branching the soft pipe joints in the horizontal direction so that the cold and hot water pipes are properly distributed to the side, making it easy to connect the pipes, and the structure of the ceiling concrete An object of the present invention is to provide a ceiling-filled distributor having a pipe connection structure capable of improving strength.
