Description

Height adjuster for synthetic resins pipe connection

The present invention relates to a height adjusting device for connecting a synthetic resin pipe, and in particular, in order to facilitate the installation of a pair of clamps at the connecting end thereof when connecting the synthetic resin pipe, a height adjusting part is installed to easily adjust the height. It relates to a height adjusting device for connecting a 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 periphery 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. '

Since the prior application having the structure as described above performs the work of directly connecting the synthetic resin pipes 40a and 40b in the field, when the place where the synthetic resin pipes 40a and 40b are to be installed is a flat ground, any problem occurs in operation. It can be performed smoothly without, but if the ground surface of the connection portion of the synthetic resin pipe (40a, 40b) to be connected is an uneven surface, that is, the pre-installed synthetic resin pipe is placed on a smooth surface, When the synthetic resin pipes 40a and 40b are connected using the pair of clamps 10a and 10b in a state where the synthetic resin pipe is uneven surface, the clamps 10a and 10b are connected to the connection portions of the synthetic resin pipes 40a and 40b. ), And the installation portions of the clamps 10a and 10b differ from each other in order to closely contact the end of the pre-set synthetic resin pipes 40a and 40b and the end of the synthetic resin pipes 40a and 40b to be installed on the clamps 10a and 10b. Compared to the part If it is because, when there is a smooth surface which is lowered compared with the water-tightness to connect the synthetic resin tube (40a, 40b) in place.

Since the ground of the connecting portion of the synthetic resin pipes 40a and 40b to be connected is an uneven surface, it has a huge effect on the clamps 10a and 10b installed there, so that the synthetic resin pipes 40a and 40b using the clamps 10a and 10b are used. The connection is not tightly connected, because the connection of the synthetic resin pipes (40a, 40b) is slightly shifted and excited, there was also a problem that the connection is not closely connected.

Thus, the present invention was devised to solve the problems as described above, to ensure that the work of the connecting portion when connecting the synthetic resin pipe smoothly on the smooth surface as well as the height of the clamp height adjustment portion It is an object of the present invention to provide a height adjusting device for connecting a synthetic resin pipe that can be easily adjusted by using.

The height adjusting device for connecting the synthetic resin pipe according to the present invention for achieving the above object is made of two bodies by dividing the end pipe having a diameter that can fit the outer circumference of the synthetic resin pipe into two ends and having a flange at one end. One end is opened and closed by a hinge coupling and the other end is folded at a right angle, a pair of clamps provided with a fastener; A plurality of hydraulic jacks installed on the outer circumference of the clamp at regular intervals to push the flanges of both clamps by hydraulic pressure; A fusion ring interposed between the synthetic resin pipes to be connected to generate heat when electricity is conducted and to weld the synthetic resin pipes which are tightly connected by the hydraulic jacks; In the synthetic resin pipe connecting device is configured,

Located on the lower surface of the pair of clamps, and installed to support it, the support portion consisting of a rectangular plate body; A plurality of legs positioned on a lower surface of the support part and integrally coupled to each other; A height adjusting part disposed at a predetermined position of the plurality of leg parts and installed to adjust a length of the leg part; Characterized in that configured.
