Abstract

This study relates to the reinforcement structure of synthetic resin pipes with large diameters. In the conventional synthetic resin pipes with large diameters, the load strength is weak and the pipes are not strong, so many defects occur due to earth pressure or lubricity after construction. The transfer is mainly used for sewage, wastewater, and wastewater. There are even pollution problems that pollute the land due to leakage.

In this paper, a grate-like reinforcement structure is formed in the hollow inside a small rectangular synthetic resin pipe, and it is continuously manufactured in a spiral circle, and the mutually-welded surfaces are bonded with adhesive resin to form a spiral node. The pipe formed as described above forms a large synthetic resin tube, so that the tube is solid and the load strength is strong to solve the conventional problems. Synthetic resin pipes with large grate-type reinforcement structure were used to be connected to the sewer pipes of urban sewage treatment plants and the sewage and waste water treatment pipes of industrial complexes.

Description

Large plastic pipe with grate type reinforcement structure {.}

The present invention is a large square synthetic resin tube formed by fusion of the mutually-welded surfaces with synthetic resin while continuously producing small square synthetic resin pipes in a spiral circle. Form the reinforcement structure of the door grate structure in the hollow inside the tube and continue to manufacture it in the spiral circle shape, and weld the mutually opposing surfaces with adhesive resin to form the spiral node, and the grate reinforcement structure is formed between the spiral nodes. It is characterized by the formation of large synthetic resin tubes.

The synthetic resin pipe with large grate-type reinforcement structure in this paper is a reinforcing bar of door grate-like structure, which is formed horizontally and vertically with the same material, and is formed mechanically.

Conventional plastic pipes with large diameters are weak in the tube body and the load strength, causing a lot of defects without being able to withstand earth pressure or lubrication pressure. In order to improve this point, conventionally, steel plates are embedded in synthetic resin pipes or engineering plastics are used to solidify the pipes and increase the load strength, but they require much attention during construction and are separated from each other. There is a problem.

In order to improve the above problems, this proposal is to make the reinforcing structure in the hollow of synthetic resin pipe with large diameter and to make it easy to manufacture, and the grate-type reinforcing structure with strong pipe, strong load strength and excellent durability is formed. The purpose is to provide a large synthetic resin pipe. In order to achieve the above object, the present invention is to form a horizontal reinforcing bar and a vertical reinforcing bar to cross each other in the hollow inside a small square synthetic resin pipe and form a body to support the pipe wall to each other, while continuously producing this in a spiral circle The surface is welded with adhesive resin to form a spiral node, and between the spiral nodes, a pipe-shaped reinforcing structure is installed between the spiral nodes, so it is strong and strong in load strength, excellent in stress and bearing capacity, and made of the same material. Durable semi-permanent grate-type reinforcement structure with large diameter synthetic resin tube was formed. Such a large diameter synthetic resin tube formed with the grate-type reinforcement structure can be easily manufactured by using an extruder and a grate mold, vacuum and cooling sizing, and a molding machine.

The present invention for achieving the object as described above will be described in detail based on the accompanying drawings.

1 is a perspective view of a portion cut to show a conventional synthetic resin pipe configuration state of large diameter. It is a tube formed by fusing the mutually opposing surfaces 12 and 13 with resin while continuously manufacturing a small square synthetic resin tube 10 in a spiral circle shape.

Figure 2 is a perspective view of a part cut to show the structure of a large synthetic resin pipe 100 is formed in the grate type reinforcement structure of the present invention. In the large diameter synthetic resin pipe of Figure 1 in the inner hollow 11 of the small square synthetic resin pipe 10, one horizontal reinforcing rod 31 and two vertical reinforcing rods 32 cross each other to form a grate-type reinforcement structure (30) While continuously manufacturing this in a spiral circle, the surfaces 12 and 13, which are mutually treated, are welded with an adhesive resin to form a fusion region with a spiral node 20, and a grate-shaped reinforcement structure 30 between the spiral nodes 20. To form a large synthetic resin tube 100 is formed with a grate-type reinforcement structure characterized in that formed. Into the inner hollow 11 of the small rectangular synthetic resin tube 10, six smaller rectangular synthetic resin tubes 33 were formed by the horizontal reinforcement 31 and the longitudinal reinforcement 32 of the grate-type reinforcement structure. The number and width of the horizontal reinforcing rod 31 and the longitudinal reinforcing bar 32 is formed by forming a plurality of smaller square tube 33 is characterized by adjusting the rigidity and strength of the tube.

As shown in the sectional view of the main portion, a grate-shaped reinforcement structure 30 is formed at each node of the tube in the inner hollow 11 of the small rectangular synthetic resin tube. The grate-type reinforcement structure 30 supports the walls of the hollow 11 and consists of one wall and one wall, and forms six smaller square tubes 33 so that the tube body is more solid and the load strength is greatly increased. The stress and bearing capacity are to be improved. In particular, the resin used for fusion was used as the adhesive resin to be more firmly fused.

In addition, the horizontal reinforcing rod 31 and the vertical reinforcing rod 32 of the grate-type reinforcing structure 30 crosses each other to form a cross-body structure having a cross-shaped (+)-type structure.

FIG. 3 illustrates a variety of grate-type reinforcement structures 30 in the inner hollow 11 of the small rectangular synthetic resin tube 10 in the large-diameter synthetic resin tube 100 in which the grate-type reinforcement structures are formed as shown in FIG. , b, c, d, and ().

In particular, since the configuration of the grate-type reinforcement structure 30 is to be formed dynamically, the effect can be further increased. And by giving a round to the corner of the rectangular square resin tube as shown in 3 C to be similar to the octagonal shape can increase the welding force in the process of fusion of the tube. Here, the number of horizontal reinforcing bars 31 and the vertical reinforcing bars 32 are different or equal to each other depending on the degree of rigidity of the pipe and the strength of the load strength. A large diameter synthetic resin tube was formed.

This paper uses a plastic extruder and a grate mold, vacuum and cooling sizing, and a molding machine to form a reinforcing bar of the grate structure in the hollow inside a small square synthetic resin tube, and then continuously manufactures it in a spiral circle to form an adhesive surface. It is formed by fusion of resin to form spiral nodes, and to form grate-type reinforcement structures between spiral nodes, forming a synthetic resin tube with a large diameter with grate-type reinforcement structures. It is molded into one body to support the hollow walls mutually, and it forms a large number of small square tubes to make the pipe strong and stress, to be strong in supporting force, and to increase the load strength. Hume occupies more than 70% of the domestic sewer pipe market Market, the load intensity is weak, but were unable to enter the large diameter plastic pipe in the paper grate type reinforcement structure is formed, is that the effect would be even larger can be entered.
