STRUCTURE FOR CONNECTING THE SEWER PIPES OR WATER PIPES}

The present invention relates to a sewage pipe connection structure for connecting water pipes, waste water pipes, or sewage pipes buried in the ground. More specifically, the coupling parts formed at the ends of the water and sewage pipes are tapered, and the water and sewage pipe connections for fastening the fastening parts with clamps. It's about structure.

1 and 2, the conventional sewage pipe connecting device is matched with the ends of the first sewage pipe (3) and the second sewer pipe 5 to each other after the rubber packing (6) the first sewer pipe (3) It is fitted to the connecting portion of the second sewer pipe (5) and is arranged to surround the rubber packing 6 of the band-type connecting means (7), a plurality of bolts (9) by tightening the connecting means (7) Two sewer pipes 3 and 5 are connected to each other.

However, such a conventional sewage pipe connecting device may cause leakage due to corrosion of the rubber packing and leakage of the sewer pipe connection due to thermal expansion and contraction, and the process of fastening the band type connection means is troublesome and has a short lifespan. There was this.

Therefore, to overcome the problems of the prior art, the present invention can prevent the leakage of the sewer pipe connection due to corrosion and thermal expansion and contraction, and to facilitate the work, the fastening portion formed at the end of the water and sewage pipe It is tapered and provides a structure for connecting the water and sewage pipes to which the fastening part is clamped.

One example of the water and sewage pipe connection structure according to the present invention for achieving the above object is that the head and the sewage pipes formed with the head portion is arranged in line with each other, before the water and sewage pipes are arranged in line with each other around the end of the water and sewage pipes The rubber packing is arranged, and the ends of the upper and the sewer pipes are arranged in line with each other, and then two clamps are fastened to the head of the upper and the sewer pipes by two bolts and two nuts.

The water and sewage pipes mean water pipes or sewage pipes. Since the connection structure of the water pipes and the sewer pipes is the same, the water and sewage pipes will be referred to as sewer pipes for simplicity and clarity.

The head portion of the sewage pipe is integrally spaced apart from the end by a predetermined interval, the vertical portion extending radially from the outer diameter surface of the sewage pipe, a horizontal portion perpendicular to the vertical portion, and the outer diameter of the sewage pipe is refracted by the horizontal portion It is characterized by consisting of an inclined portion extending to the surface.

The inclination angle of the inclined portion is characterized in that the inclination of 30 ° with respect to the normal line.

The rubber packing is characterized in that the inner diameter is the same as the outer diameter of the sewage pipe, the outer diameter is the same as the horizontal portion of the head of the sewage pipe, and the thickness is slightly larger than twice the predetermined interval of the ends.

The clamp is composed of two flanges fastened by bolts and nuts, and a semi-circular body portion connecting the two flanges.

The body portion has a cross-sectional shape of the inner circumferential surface 'c' shape, the inclined portion is formed at the end, characterized in that the inclined portion is in close contact with the inclined portion of the head portion of the sewer pipe.

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

3 to 5, the sewage pipe connection structure according to the present invention is provided with sewage pipes 11 and 11 ′ in which the head part 15 is formed in a row, and the sewer pipes 11 and 11 ′ are in line with each other. The rubber packing 23 is arranged around the end 20 of the sewage pipes 11 and 11 'before being placed in the furnace, and the two clamps after the end 20 of the sewage pipes 11 and 11' are arranged in line with each other. 25, 25 'is the head 15 of the sewer pipes 11, 11' by two bolts 35, 36 (see FIGS. 4 and 5) and nuts 37, 38 (see FIGS. 4 and 5). ) Is fastened.

Referring to FIG. 6, the sewage pipes are arranged in line with each other, and since the shape and function are the same, only the sewer pipe 11 will be described below.

The head portion 15 of the sewage pipe 11 is integrally formed at a predetermined distance d from the end portion 20, and is vertically formed to extend radially from the outer diameter surface 12 of the sewage pipe 11. The horizontal portion 17 perpendicular to the vertical portion 16 and the inclined portion 18 that is refracted by the horizontal portion 17 and extends to the outer diameter surface 12 of the sewer pipe 11.

The inclination angle α of the inclined portion 18 makes an inclination of 30 ° with respect to the normal line (shown by dashed line). When the inclination angle α is 30 ° or less, the clamping force of the clamps 25 and 25 'may be weak, and leakage may occur. This is not easy and the task is difficult.

Referring to FIG. 3, the rubber packing 23 has an inner diameter equal to the outer diameter of the sewage pipe 11, and an outer diameter equals the horizontal part 17 of the head 15 of the sewage pipe 11, and has a thickness at an end portion ( It is slightly larger than twice the predetermined interval d of 20). As a result, the rubber packing 23 does not protrude from the sewer pipe 11, and when the clamps 25 and 25 ′ are tightened, the rubber packing 23 is compressed to close the gap between the sewer pipes 11 and 11 ′. It prevents water leakage by preventing it.

Only one of the clamps 25 and 25 'shown in Figs. 3 to 5 are symmetrical to each other.

Referring to FIG. 3, the clamp 25 connects two flanges 26 and 27 fastened by bolts 35 and 36 and nuts 37 and 38, and connects the two flanges 26 and 27. The semicircular body portion 28 is composed of.

Referring to FIG. 4, the body portion 28 has a cross-sectional shape of an inner circumferential surface of a 'c' shape, and slopes 29 and 30 are formed at ends thereof, and the slopes 29 and 30 are sewer pipes 11. Is in close contact with the inclined portion 18 of the head portion 15.

The water and sewage pipe connecting structure of the present invention configured as described above has two sewer pipes 11 and 11 'in line with each other while the rubber packing 23 is fitted around the end 20 of the sewage pipes 11 and 11'. And two clamps 25, 25 ′ are then fastened to the head 15 of the sewer pipes 11, 11 ′ by two bolts 35, 36 and nuts 37, 38. At this time, the inclined portions 29 and 30 of the main body 28 of the clamp 25 press the inclined portions 18 of the head portion 15 of the sewage pipes 11 and 11 ', thereby providing two sewage pipes 11 and 11'. The ends 20 of) are completely in contact with each other, and the ends of the sewer pipes 11 and 11 'are sealed by the rubber packing 23. In this way, the pressurizing action of the clamp 25 and the compressed rubber packing 23 prevent leakage of the sewer pipe.

The water and sewage pipe connecting structure according to the present invention is prevented from leaking of the sewer pipe connection part due to corrosion and thermal expansion and contraction, and the sewage pipe and clamp can be transported separately to the work site. This convenient, simple operation of tightening the two bolts from the left and right side can connect the sewer pipes to each other, the operation is easy.

Embodiment of the water and sewage pipe connection structure according to the present invention described above is for illustrating the idea of the present invention, the present invention is not limited to the embodiment described above. Those skilled in the art will be able to modify the connection structure of water and sewage pipes according to the present invention without departing from the utility model registration claims attached to various methods.
