It is a technology related to building extrusion pipes with excellent production and productivity.

In general, synthetic pipes, such as soft hoses or rigid pipes, are molded by an extruder that extrudes raw materials for a long time, and most of the granular or powdered synthetic resin raw materials put into the hopper of the extruder are heated and heated by a heater in a cylindrical cylinder. And after being melted, it is forcibly transported to the outlet while being kneaded and compressed by the rotation of the screw, and is extruded into a hole shape of a die mounted on the outlet.

These synthetic resin pipes are extruded in various shapes such as round or square according to the shape of dies in the extruder, and are light in weight for easy handling and transportation, and use adhesives, sockets, butt fusion methods, etc. It has the advantage of easy joining, connection and repair, but has the disadvantage of relatively low impact and strength.

Doing.

In addition, as a representative prior art for reinforcing the strength of a conventional synthetic resin tube, Korean Patent Registration No. 10-0873007 (synthetic resin tube having a reinforcement means) has been proposed.

The prior art has an inner wall forming a flow path space in the longitudinal direction, an outer wall surrounding the inner wall, and between the inner wall and the outer wall, a body in which a hollow portion is continuously or discontinuously formed, and a reinforcing means for reinforcing the strength of the body It is provided, the reinforcing means is a technology that is filled with a hollow portion of the main body and provided with a reinforcing material formed by mixing powder containing polyethylene and metal powder.

However, the prior art has a problem that the structure of the synthetic resin tube is very complicated, and thus, the production cost is excessively high. Also, as the heterogeneous materials other than the synthetic resin are mixed and manufactured, it is difficult to recycle the synthetic resin tube. have.

Accordingly, the present applicant has proposed the Republic of Korea Patent No. 10-1752683 (extruded tube with partitions) as a method for use in various applications while reinforcing the strength of the synthetic resin extrusion tube.

In the prior art proposed by the present applicant, the partitions for the water barriers are formed at regular intervals in the hollow holes of the extruded pipes formed by the extruder, and cut into predetermined lengths depending on the purpose of use, such as temporary bridges or farms. It is easy to install as a floating float of the product, has excellent production and productivity, as well as low production cost, and provides a recyclable effect.

Looking at the main configuration according to an embodiment of the present invention with reference to the accompanying drawings, in the synthetic resin extrusion pipe 10 continuously formed through an extrusion molding machine, the hollow hole 11 of the extrusion pipe 10 is constant At intervals, the partition 20 is introduced and joined, and the tape 30a is formed by winding the tape 30a in the longitudinal direction outside the extrusion pipe 10.

In the embodiment of the present invention, the extrusion pipe 10 in which the partition 20 is formed in the hollow hole 11 is continuously molded through an extrusion molding machine, as shown in FIGS. 1 to 3 in the drawing, of the extruder 100 Heated from the cylinder to the heater, the softened and melted raw materials are kneaded and compressed by the drive of a screw, forcibly transferred to the die head 110 and the die 120, and extruded from the die 120 to the sizing 130 to form a vacuum. do.

At this time, the cylinder 210 is operated in the partition loading unit 200 to adsorb the partition 20 stacked on the cartridge through the adsorption head 220, and then the vacuum tube is extruded in the sizing 130. It is injected into the hollow hole (11).

Here, the partition 20 introduced into the hollow hole 11 of the extrusion pipe 10 is joined around the inner circumferential surface of the hollow hole 11, and the extrusion pipe 10 is cooled while the extrusion pipe 10 is cooled in the cooler 140. ) The partition 20 is configured to be joined to the hollow hole 11 at regular intervals.

Therefore, the partition 20 is configured to be bonded at regular intervals to the hollow hole 11 of the extrusion pipe 10 that is continuously molded through the extrusion molding machine, and also the partition 20 from the hollow hole 11 of the extrusion pipe 10 ) And the space between the partitions 20 is sealed.

In the main configuration of the above embodiment, the extrusion pipe 10 in which the partition 20 is formed in the hollow hole 11 is wound on the outside of the extrusion pipe 10 by winding the tape 30a in the longitudinal direction on the outside as shown in FIG. 4. The taping layer 30 is configured.

In the tape 30a constituting the taping layer 30, it is preferable to apply aramid fibers having excellent tensile strength, toughness, and heat resistance, and in the longitudinal direction so that the extruded tube 10 is not exposed to the outside. The tape 30 is formed by winding the tape 30a to overlap.

Meanwhile, as shown in FIG. 5 in the drawing, the tape 30a is wound in one direction by winding the tape 30a along the length direction on the outside of the extrusion pipe 10, and then the tape 30a is crossed with the tape 30 The tape 30b may be wound again in the direction to configure the taping layer 30 in double.

The tapes 30a and 30b constituting the taping layer 30 may be attached to the outside of the extrusion pipe 10 by applying an adhesive to the outside of the extrusion pipe 10 or applying an adhesive to the attachment surface. .

In addition, the taping layer 30 may be constructed by weaving aramid fibers on the outside of the extruded pipe 10, which is continuously molded by installing a weaving machine of known technology around the outer periphery of the extruded pipe 10. An aramid fiber may be woven on the outside of the extrusion pipe 10 to form the taping layer 30.

Therefore, as the partition 20 is formed at a predetermined interval to the hollow hole 11 of the extrusion pipe 10, the strength of the extrusion pipe 10 is increased while the tape made of aramid fibers on the outside of the extrusion pipe 10 ( By constructing the taping layer 30 by winding 30a) (30b) or by weaving aramid fibers, the durability and strength of the extruded tube 10 are excellent and the load is reduced.

A plurality of holes 40 are formed through the outer circumferential surface so as to be positioned at

Here, the hole 40 located on one side is a function for filling the foamable foam foam interior material 50 in a closed space between the partition 20 and the partition 20, as shown in FIG. 9 in the drawing, and the hole located on the other side (40) is a function in which air is discharged to the outside during the filling process of the interior material (50).

In addition, the embodiment of the present invention, as shown in FIG. 10 in the drawing, it is possible to configure the taping layer 30 on the outside of the extruded pipe 10 at regular intervals, in this case, the extruded pipe in the portion without the taping layer 30 ( Since the tensile strength and toughness of 10) are reduced, the extruded pipe 10 can be rolled up in a roll form to be easily loaded or transported.

Embodiments of the present invention made of such a configuration can be used for a variety of purposes in the construction or various industrial equipment extruded pipes, also filled with a foamable foam foam interior material in a closed space between the partition and the temporary temporary bridge (浮橋) or farm It can be installed in a variety of ways such as floating floats.

In addition, in the embodiment of the present invention, since the extruded pipe is first constructed in a building or various industrial facilities, a hole is drilled in the outside, and a foamable foam foam interior material can be filled in an enclosed space between the partition and the partition. This is excellent.
