Description

Position fixer for synthetic resins pipe connection

The present invention relates to a position fixing tool for connecting a synthetic resin pipe, and more particularly, to a position fixing tool for connecting a synthetic resin pipe to accurately grasp the center position of a synthetic resin pipe to be connected when connecting the synthetic resin pipe.

In general, synthetic resin pipes are extruded into small square tubes and spirally wound with large concentric circles to form large-diameter tubes by fusion or bonding. At this time, a space is formed inside the square tube, which exists between the inner wall and the outer wall. It is called a double walled pipe because it plays the same role as a space.

The synthetic resin pipe is not only having flexibility and appropriate strength, but also having good corrosion resistance, which is mainly used for transporting fluids buried underground, that is, it is widely used for drainage pipes such as sewerage.

Here, the synthetic resin pipes as described above because the length is constant, when inevitably connected to the construction by using a molding machine at the end of the synthetic resin pipe connected in the field by using a molding machine, the flange was fastened by bolts.

However, the conventional synthetic resin pipes as described above have a disadvantage that the molding machine must be separately provided according to the diameter of the synthetic resin pipe because the diameters are different, and the volume of the molding machine is so large that the site conditions when connecting the synthetic resin pipes In many cases, it was difficult to form a synthetic resin pipe.

In addition, since the work of molding the synthetic resin pipe in the field has to be accompanied by various operations such as work to melt the synthetic resin, there was also a problem inferior workability.

In order to solve the problems as described above, the applicant of the present application has filed a patent application No. 2001-5467 synthetic resin pipe fusion connection device.

Looking at the contents of the above application, 'In connecting the synthetic resin pipe, the short pipe having a flange 12 at one end having a diameter that can be pressed and wound around the synthetic resin pipe (40a, 40b) to be connected by dividing into two Composed of two bodies (11a, 11b, 11c, 11d), the one end is cut and hinged to open and close, while the opposite end is folded at a right angle to the pair of clamps (10a, 10b) )Wow;

A plurality of hydraulic jacks (20) installed on the outer circumference of the clamps (10a, 10b) at regular intervals to push the flanges 12 of both clamps (10a, 10b) by oil pressure; Interposed between the synthetic resin pipes (40a, 40b) to be connected is generated by fusion ring (30a) for fusion to the synthetic resin pipes (40a, 40b) to be heated by electricity when the electric conduction is in close contact with the hydraulic jack 20 Synthetic resin pipe fusion splicing device. '

Here, the first application having the structure as described above is a synthetic resin pipe (40a, 40b) by a hydraulic cylinder 22 built by installing a pair of clamps (10a, 10b) at the connection end of the synthetic resin pipe (40a, 40b) While close contact with each other, there is an advantage that the connection between the synthetic resin pipes (40a, 40b) can be tightly and firmly constructed by applying heat through the fusion ring (30a) between the connection ends and the electricity.

However, while having the advantages as described above, the prior application is to close the synthetic resin pipes (40a, 40b) to be connected when connecting the synthetic resin pipes (40a, 40b) in the field between the fusion ring (30a) therebetween Open the body 11a, 11b, 11c, 11d of the hinged clamps 10a, 10b in the state to position the ends of both synthetic resin pipes 40a, 40b, and then fold the clamps 10a, 10b to clamp 10a, 10b) wraps the outer peripheral surface of the end of the synthetic resin pipe (40a, 40b) to be connected, and then rotate the screw rod 15 toward the end of the opposite body (11a, 11b, 11c, 11d) fastening groove formed in the opposite position After inserting in the fastening nut 16 to tighten the outer peripheral surface of the two synthetic resin pipes (40a, 40b) that are eventually connected to the bar firmly coupled,

That is, when the synthetic resin pipes 40a and 40b are connected, the process of accurately positioning the synthetic resin pipes 40a and 40b to be connected in the clamps 10a and 10b as part of an initial operation is very difficult.

This is because the following work must be carried out after the two ends of the synthetic resin pipes 40a and 40b in which the fusion ring 30a is interposed in the center part exactly bisected to the right and left in the clamps 10a and 10b. The connection of the pipes 40a and 40b can be made precisely and tightly. If the subsequent work proceeds without the synthetic resin pipes 40a and 40b not located in the clamps 10a and 10b0, the synthetic pipe 40a , 40b) does not maintain the strength of the connection portion is not constant, there is a problem that shows a non-uniform strength difference, and there is a problem in that the adhesive strength and water tightness of the synthetic resin pipes (40a, 40b) is lowered because the coupling force of the connection portion is lowered.

Thus, the present invention has been devised to solve the problems described above, it is possible to precisely grasp the center position of the synthetic resin tube to be connected when connecting the synthetic resin tube to facilitate the connection of the synthetic resin tube Its purpose is to provide a positioning fixture for connecting a synthetic resin pipe.
