Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a connection structure for a drainage pipe,

The present invention relates to a drainage pipe connecting structure of a left-hand side which is connected to upper and lower layers in a multi-story building, and more particularly, to a structure for reducing drainage water while reducing noise that may be generated in a lower layer.

More particularly, the present invention aims at providing ease of installation due to a simple assembly structure and minimizing noise generated at the time of water drop, while facilitating water drainage and ease of water cooling.

In the present multi-storey building, the upper shelf of the upper level is installed, and the el shelf for draining the water from the left upper shelf of the upper storey is installed on the roof of the lower storey. In the lower storey for the drainage, A means for normally blocking the noise is provided in order to cut off the generated noise.

Therefore, the noise can be prevented by providing the noise-isolating means when the drainage water drops.

However, in the case where the concrete is installed in a multi-layered building such as an apartment or a tenement house in order to divide the floor between concrete, And the el arch is connected to the through sleeve by the assembly of the worker.

However, when the connecting operation of the El storing is performed by inserting the elongated tube of the el arch into the engaging groove at the lower end of the through sleeve and forming the engaging groove at the lower end of the through sleeve, And the packing is tightly coupled to the coupling hinge so that the coupling is difficult. Therefore, most of the worker can not complete the coupling and only a certain portion of the coupling is engaged. As a result, a gap may be generated It will be.

In addition, such a gap is not only careless by a worker but also a worker may well be careful that the penetrating sleeve is buried between the layers so that when the concrete is poured in order to tightly fill the concrete, A deformation occurs.

Therefore, a gap may be generated due to the problem that the complete coupling can not be performed due to the angular deformation.

In addition, if the smoothness is not maintained during the installation of the concrete used for casting, if the roof surface exposed at the lower roof is inclined or rugged, it is impossible to precisely connect vertical sleeves and el arches, .

Also, since the through sleeve can not protrude from the bottom surface (roof) of the lower layer when the lower shelf is embedded in the bottom of the upper and lower layers, In this case, the problem becomes quite difficult.

In addition, in order to prevent water leakage and prevent noise, when the vertical tube of the el arch is inserted into the engaging groove of the lower end of the penetrating sleeve, the packing is used, and such packing makes it difficult to engage with the lower end of the penetrating sleeve.

As a result, there is a case where the area where the elec- tric storage device with the noise prevention means is combined with the through sleeve can not be accurately connected due to the above-mentioned reason, and the noise is generated due to such a gap and the complaint is continuously generated due to such noise at the lower layer of the multi- There is a problem.

Therefore, according to the present invention, even when a clearance is formed between a portion where the el sleeve and the through sleeve are engaged, the clearance can be blocked from the inside of the through sleeve, thereby reducing noise generation by simple construction.

In addition, in order to prevent the vacuum from being induced when the water is lowered by such blocking, the air passage is formed while blocking the noise.

The upper end having a space for fitting the connection pipe, which can be seated on the latching support frame provided on the inner side of the penetrating sleeve, and a part of the vertical pipe of the elastic storage in a state where the elastic storage is coupled to the lower end of the penetrating sleeve A socket having a lower end portion is assembled to cut off a gap generated when the through sleeve and the el arch are combined.

In addition, in order to prevent a vacuum from being generated by assembling the socket when the water is lowered, a ventilator is provided in a state where the socket is coupled.

And the ventilation passage is provided in the form of an inner groove which is inserted into the inner or outer surface of the socket.

In addition, the ventilation passage may be provided with two or more protruding lines protruding from the inner or outer surface of the socket.

In addition, one side of the socket is cut open so that the two sockets having the openings are overlapped with each other so that the openings are overlapped with each other, and the ventilator is provided on the inner and outer sides of the overlapped socket.

Therefore, when the through sleeve is embedded in the interlayer between the upper and lower layers, the elec- trode connected to the lower layer is connected to the coupling groove formed in the through sleeve. When the socket is inserted from the upper layer of the through sleeve in this state, It is possible to minimize the occurrence of noise even when there is a clearance in the state where the through hole is engaged with the coupling groove of the elongated sleeve when the water in the left side lid falls.

As a result of the experiment in the present invention, it was confirmed that 4 dB was reduced.

Further, by forming the air passage on the inner side surface or the outer side surface of the socket, it is possible to eliminate the occurrence of the vacuum degree at the time of water drop by combining the socket, thereby making it possible to prevent the noise as well as to lower the water.

In addition, when forming the ventilation path, the one side of the socket is cut open so that the two sockets are overlapped with each other, so that the opening forms the ventilation passage, and the opening of the ventilation passage forms the ventilation passage, It is possible to reduce the occurrence even more, but it is also possible to use it for watering down.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 to 5, the components of the present invention are embedded in a bottom layer 100 forming an interlayer in a multi-layered building, and include a catching frame 11 for catching a socket 20 to be assembled therein, And a coupling hinge (12) to which the vertical tube (31) of the el arch (30) can be inserted at the lower end of the through sleeve (10);

A socket 20 which is assembled while being inserted into the penetrating sleeve 10 to be engaged with the catching receptacle 11 so as to maintain its assembled state while being prevented from dropping downward;

A vertical tube 31 fitted to the coupling hut 12 provided at the lower end of the penetrating sleeve 10 using packing or the like and a horizontal tube 32 extending from the vertical tube 31 are provided (30);

And a connection pipe (40) connected to the left side machine (200) by being inserted into the upper side of the through sleeve (10).

In the coupling of the above configuration, the socket 20 to be inserted into the through sleeve 10 has an upper end portion 22 having a larger diameter and a lower end portion 23 having a smaller diameter than the upper end portion 22, 22 and the lower end portion 23 of the socket 20 is bent.

At this time, the outer side of the step 21 of the inserted socket 20 is supported by the receiving frame 11 of the through sleeve 10 and is prevented from dropping downward while being inserted into the through sleeve 10, 23 are hooked so as to realize an appropriate coupling position.

A part of the distal end 23a of the lower end 23 of the socket 20 is engaged with the engaging frame 12 formed at the lower end of the through sleeve 10 As shown in FIG. 1, a certain portion of the vertical tube 31 of the el arch 30, that is, the horizontal tube 32, is inserted into the socket 20 while the socket 20 is engaged.

Therefore, when the through sleeve 10 and the el arch 30 are hermetically coupled to each other, the position of the through sleeve 10 can be adjusted by the pressure generated when the worker immerses in the work or the concrete is pushed, The through sleeves 10, which are generated even when the el arch 30 is correctly vertically coupled due to a change in the angle generated when the elastics 30 are bent or due to the bending caused by the ruggedness of the exposed surface of the lower layer exposed in the concrete pouring, And the lower end 23 of the socket 20 blocks the noise that is exposed through such a gap.

The upper end portion 22 having a larger diameter than the lower end portion 23 of the socket 20 is connected to the left toilet 100 in a state where the socket 20 is supported by the catching receptacle 11 of the penetrating sleeve 10, The connection pipe 40 is connected to the left side 200 of the space 1 between the through sleeve 10 and the socket 20 by inserting the connection pipe 40 into the space 1, It is possible.

Therefore, the connection of the connection pipe 40 is fitted into the space 1 formed by the socket 20, so that the connection pipe 40 can be tightly and firmly and hermetically coupled, thereby reducing noise.

At this time, however, the ventilation passage 24 must be formed in a state where the socket 20 is coupled. If the ventilation passage 24 is not formed, the gap between the through sleeve 10 and the elastics 30 The vacuum may be induced by the sealing, so that the water can not be dropped, or after the water is drained, there may be a problem that water is not generated in the toilet 100.

Therefore, in the present invention, in order to form the ventilation passage 24 in a state where the socket 20 is engaged, the inner groove and the outer side of the socket 20, as shown in FIG. 4, 24a are formed to form the ventilation passages 24.

However, in this case, when the thickness of the socket 20 is thinned at the portion where the inner groove 24a is formed, if the noise can be exposed at that portion, the thickness of the socket can be increased by injection molding .

In order to solve such a problem, as shown in FIG. 5, a protruding line 24b is formed by two or more lines spaced apart by a predetermined distance from the inner side surface or the outer side surface of the socket 20, It is possible to provide the ventilation passage 24 so that the above problems can be solved.

2 and 3, the side walls of the socket 20 are cut to form the openings 25, and the sockets 20-1 and 20-2 provided with the openings 25 are cut into two The openings 25a are overlapped with each other in a superimposed state so as to form the ventilation passages 24 on the inner side surface and the outer side surface of the overlapped socket 20a.

3, the opening of the socket 20-1 on the inner side of the stacked socket 20a is formed to have a narrow cutting width, so that when the outer socket is engaged, So that the diameter of the connecting pipe having a certain size to be inserted into the space formed when the outer diameter of the overlapped socket is inserted into the through sleeve should be able to be interposed.

However, in this method, as shown in FIG. 2, when the inner socket 20-1 is made smaller than the diameter using only one socket, the outer socket 20-2 having the opening 25a, The connection pipe having a predetermined diameter can be inserted, and the same effect of forming the ventilation passage 24 can be obtained.

Therefore, the thickness of the overlapped socket 20a is increased by the overlap, so that it is possible to further reduce the occurrence of noise due to the overlap, and this overlapping can be prevented by the opening portions 25-1 and 25-2 of the respective sockets 20-1 and 20-2 And 25a, as well as the close contact of the socket 20a superimposed by the air gap, and the position of the ventilation path 24 can be changed in various directions, It is possible to solve the clogging of the ventilation holes and to further improve the resolution of the vacuum degree.

The socket 20 according to the present invention is described as a general injection-molded plastic. However, when the socket 20 is foam-molded, the noise can be more effectively cut off.
