Description

{The jointing structure of pipe with socket}

The present invention relates to a connection structure of a synthetic resin pipe that connects the synthetic resin pipes to each other, and more particularly, the watertight along the inner circumferential surface of the socket pipe and the socket tube for tightly inserting and inserting the synthetic resin pipe at both ends, Protruding fitting packing is formed, the synthetic resin tube inserted into one side of the socket tube is welded and connected, and the synthetic resin tube inserted into the other side is pressed into the fitting packing, thereby connecting the synthetic resin tube provided on both sides of the socket tube. The present invention relates to a connection structure of a socket-integrated synthetic resin pipe, which is easily and tightly connected, and the watertight protrusion maintains watertightness and bonding strength even after repeated shrinkage and expansion by uniformly and continuously compressing the synthetic resin pipe.

As is well known, synthetic resin pipes are used in the ground for the transfer of non-pressure fluids such as water and sewage underground. Synthetic resin pipes that are lightweight and have high corrosion resistance, can be easily molded, and can be manufactured at low cost are used for water and sewage pipes. It is used for a wide range of purposes from everyday life to various industrial facilities.

The universally used synthetic resin pipe is manufactured in a certain length unit to facilitate storage and transport, and during construction, the synthetic resin pipe of length unit is continuously formed in the site while connecting the length of the synthetic resin pipe directly and continuously in the field. Therefore, there is a demand for a method of connecting the synthetic resin pipes connected to each other so as to have a certain water tightness.

The method of thermal bonding of the synthetic resin tube is a method of melting and bonding both ends of the synthetic resin tube integrally by using a thermal bonding device of a separate connecting device, but the connection performance is good, but the joint part is easily separated due to external force, and the cause of rain, etc. Due to this, it is impossible to work if water gets on the outside of the plastic pipe, and there is a problem that requires a separate heat bonder when working, and it takes a lot of time to work. There was a problem such as deterioration.

Therefore, generally, a flange type connecting the flanges of the synthetic resin pipes adjacent to each other using a bolt-nut coupling, or a method of forming and inserting the expansion pipes through which one side of the pipe is expanded is generally used. Since flange type must be integrally formed at both ends when manufacturing synthetic resin pipe, manufacturing time and manufacturing cost increase due to complicated manufacturing method, and because only one side of flange is fixed, Due to this, the joints of the flanges are easily broken and the post-processing parts of the flanges are weakened, causing leakage. The plastic pipes are repeatedly contracted and expanded due to temperature differences due to seasonal and day-to-day temperature changes. This repetitive contraction and expansion causes one side of the It is going to damage or impatient there were a lot of problems, such as the cause of the leaks and damage.

In addition, the method of forming the expansion pipe on one side of the synthetic resin pipe, the expansion pipe is not expanded to the exact dimensions, when the end of the neighboring synthetic resin pipe is inserted into the expansion pipe rubber packing installed therein of the synthetic resin pipe It is frequently torn by the end, and once connected, the resin tube cannot be loosened and reconnected, and it takes time and manufacturing cost to separately form the resin tube, such as forming an expansion portion or forming a screw thread for easy joining. There was a problem such as increase.

Therefore, the present invention has been made to solve the above problems, in connecting a synthetic resin tube of a general form, by inserting the synthetic resin tube to be connected to each other at both ends by connecting the synthetic resin tube by welding and packing method, respectively, An object of the present invention is to construct a connection structure of a socket-integrated synthetic resin pipe that is easily and intimately connected and continuously maintains watertightness and bonding force even after repeated shrinkage and expansion by the elastic force of the tightly packed packing.

The present invention for solving the above problems, the socket tube for tightly inserting and inserting the synthetic resin tube into both ends and the watertight protrusion protruding toward the inside along the inner circumferential surface protrudes at regular intervals while being closely adhered and inserted into the inside of the socket tube Forming a fitting packing; One side of the socket tube is pressed and inserted into the synthetic resin tube, and the parts connected to each other are welded, and the other side is pressed against the inside of the socket tube, and the synthetic resin tube is pushed into the fitting packing. It constructs the connection structure of the synthetic resin pipe connected to the outer circumferential surface of the synthetic resin pipe.

At this time, the watertight protrusion of the fitting packing is composed of a support body having a hardness of 70A or more protruding in the form of a square column and a watertight body having a hardness of 40A or less, the ends of which are circularly formed in the form extending to the upper end of the support, and the support body extends to the outer peripheral surface of the fitting packing. It protrudes and forms a flange protruding outward along the fitting packing rear end.

Through this, by connecting the synthetic resin tube inserted into both sides of the socket tube by the interference fit method in the welding and fitting packing, it is possible to easily connect the general synthetic resin tube without the manufacture of a separate synthetic resin tube, and tightly connected by the socket tube while maintaining the elastic force The watertight projections hold the synthetic resin pipes evenly, so that the tightly connected plastic pipes maintain high watertightness even when the internal and external impact is applied or repeated shrinkage and expansion of the plastic pipes occurs due to temperature changes. Has

In addition, the watertight protrusion consisting of the support and the watertight body tightly presses the synthetic resin tube by the resilient elasticity of the crimped support, and the watertight body is brought into close contact with the synthetic resin tube so that the synthetic resin tube tightly inserted into the fitting packing can be tightly and tightly connected. When the fitting is inserted into the socket tube, it extends to the outer peripheral surface of the fitting packing, and the protruding support adheres to the socket tube to have a high resistance to prevent the fitting packing from falling out of the socket tube, and the flange is caught and fixed to the socket tube end. It has the effect of accurately inserting the fitting into the socket tube.
