Abstract
The utility model aims at providing a steel-strip reinforced section and a plastic-steel compound enwound drainage pipe material manufactured by same. The metal-strip reinforced section can be used for manufacturing drainage pipes in factories or in the field. The utility model also aims at manufacturing the plastic-steel enwound drainage pipe material which is manufactured by helically enwinding and welding the steel-strip reinforced section; by adopting the relatively simple and stable reinforcing structure, the raw material is saved and the cost and installation and transportation charges can be reduced with the external pressure resistance guaranteed. In order to realize the aims, the reinforcement in the steel-strip reinforced plastic dual-hole section is the stiffener which is compounded with the steel strip; the steel-strip reinforced reinforcement is arranged in the middle part of dual-hole section; the plastic-steel compound enwound drainage pipe manufactured by the steel-strip reinforced section is formed by helically enwinding the steel-strip reinforced section and welding the steel-strip reinforced section with the fusing plastic. The steel-strip reinforced section has the advantages that the structure is simple and stable, the section is easy to machine and manufacture, the consumption quantity of the raw material is low, the installation and transportation are convenient, the construction is simple and convenient and the engineering manufacturing cost is low.
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.
Background technique
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 ZL01 2 17543.x " plastic tube that tube wall is helically-wound shaped " are 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, existing questions in particularly applying for for ZL 01 2 17543.x numbers, basic design of the present utility model is: substantial improvement in addition on the basis of ZL 01 2 17543.x patents, 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 purpose of this utility model is to provide a kind of steel band reinforcing profile, and it can be used for factory or site preparation waste pipe.
Another purpose of the present utility model 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 that the utility model provides 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 width; Can punch on the steel band that is used to strengthen, the hole can be circular, 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) fillet is arranged, the rectangular that (or not having) fillet is arranged, circle, octagon or other are irregularly shaped.
The plastic-steel composite wound drain pipe of steel band reinforcing profile of the present utility model 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.
The utility model has the advantages that: simple and stable structure, 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.
Description of drawings
Accompanying drawing 1 be one of the utility model steel band reinforced plastic section bar most preferred embodiment sectional view.
Accompanying drawing 2 is one of plastic-steel composite wound drain pipe most preferred embodiments of the utility model steel band reinforcing profile manufacturing, gets one section part section structural representation of tubing.
Accompanying drawing 3 is local section structural representations in the accompanying drawing 2 that has amplified.
Embodiment:
Most preferred embodiment in conjunction with the accompanying drawings further describes feature of the present utility model as follows:
The steel band reinforced plastic section bar be shown among Fig. 1 be by two side by side plastics single tube [1] and be welded by the plastic welding rod [2] that is coated with steel band [3].The plastic welding rod that is coated with steel band becomes the strength bar of section bar.
Fig. 2 is that the steel band reinforced plastic section bar curls spiral winding on the machine by spiral, form tubulose, the plastic-steel composite wound drain pipe that after being welded to each other cooling and shaping with molten plastic [4] between two steel band reinforced plastic section bar sidewalls that face mutually that spiral twines, obtains.
