Abstract
The invention aims to provide a steel strip reinforced section, which can be used for making drain pipes in factories or on site. The invention also aims to make a plastic-steel composite wound drain pipe by using a spiral wound welded steel strip reinforced section. The simple and stable reinforced structure saves raw materials under the conditions of ensuring needed external pressure resistance, and reduces cost and installation and transportation expenses. In order to fulfill the aims, ribs in the steel strip reinforced plastic dual-hole section are reinforced ribs composited with the steel strip, and the steel strip reinforced ribs are positioned on the middle part of the dual-hole section. The plastic-steel composite wound drain pipe made of the steel strip reinforced section is formed by spirally winding the steel strip reinforced section, welding the section with melted plastic and cutting the partial outer surface of the section. The steel strip reinforced section has the advantages of simple and stable structure, easy processing and manufacturing, low dosage of raw materials, convenient installation and transportation, simple and convenient construction and low project cost.
Description
Technical field
A kind of plastic-steel composite wound drain pipe belongs to building municipal drainage engineering tubing technical field, is mainly used in urban engineering project plumbing main conduit.
Technical background
In the prior art, urban engineering project plumbing main conduit, generally all adopt materials used for cement pipes, the a large amount of reinforcing bar of this tubing consumption, cement, heavy and not corrosion-resistant, installation and transportation inconvenience, the difficult maintenance of easy to leak, working life is short, one amount is damaged, can only abandon it, can't reclaim and cause new pollution, the patent No. of the design people's design is that ZL01217543.x " plastic tube that tube wall is helically-wound shaped " is though product can overcome the shortcoming of cement pipe, but because the Young's modulus of used material polyethylene etc. is on the low side in the production technology, have only 630-800MPa, the raw material consumption is big and pipe material product is thick and heavy, the cost height during middle heavy caliber production; The application carries out substantial improvement on above application basis, strengthen raising product ring stiffness by the steel band that increases Young's modulus 195000-220000MPa, reduce the plastic raw material consumption, reduce the pipe material product wall thickness, make it under low raw material consumption, have high critical external compressive resistance ability, can be applied in the construction project draining main conduit engineering.
Summary of the invention
Requirement according to drainage pipe in the municipal drainage engineering, at prior art, ZL 01217543.x number existing questions in first to file particularly, basic design of the present invention is: substantial improvement in addition on the basis of ZL 01217543.x patent, promptly in helically-wound shaped plastic tube wall, increase by a strip metal steel band, with increase tubing critical external compressive resistance ability, and the truncated section outer wall is to reduce quantity of plastics more.
The object of the present invention is to provide a kind of steel band reinforcing profile, it can be used for factory or site preparation waste pipe.
Another object of the present invention is to twine welding steel band reinforcing profile by spiral to make plastic-steel composite wound drain pipe, with the enhancing structure of its relative simple and stable, guaranteeing to save raw material under the required critical external compressive resistance ability, reduces cost and the installation and transportation expense.
For achieving the above object, the muscle in the steel band reinforced plastic diplopore section bar provided by the invention is the strength bar that is compounded with steel band, and the steel band strength bar is positioned at diplopore section bar middle part; The thickness of the steel band that is used to strengthen is the 2-90% of strength bar thickness; The width of the steel band that is used to strengthen is the 2-90% of strength bar height; Can punch on the steel band that is used to strengthen, the hole can be a garden shape, square or other is irregularly shaped; Used plastics can be polyethylene, polypropylene, PVC or thermoplastic blend (as: polyethylene and polyacrylic blend) etc.The shape in two holes of diplopore section bar can be that the square that (or not having) angle, garden is arranged, the rectangular that (or not having) angle, garden is arranged, garden shape, octagon or other are irregularly shaped.
The plastic-steel composite wound drain pipe of steel band reinforcing profile of the present invention manufacturing is to go section bar part (or all) outer surface to form by the steel band reinforcing profile by the spiral winding and with molten plastic welding and cutting.
Advantage of the present invention is: simple and stable structure, and manufacturing easily, the raw material consumption is low, and the product substance is light, is convenient to installation and transportation, easy construction, engineering cost is low, the intensity height, the life-span is long.
