Description
Technical field
This utility model is related to conveyance conduit, particularly a kind of high intensity, heavy caliber and the double flat that can be produced at the scene
Wall plastic-steel spirally-wound pipe.
Background technology
In existing PVC-U RPVCs winding Manifold technology, ring stiffness will reach 8KN/m2More than, can only increase
The wall thickness of pipeline, in addition it is double-deck, three layers it is compound could meet pipeline strength requirement, meter Chong is very big, and cost is very high；Existing
In plastic-steel-wound Manifold technology, by steel band and the combination of plastics, the elastic modelling quantity of composite is substantially increased, be increased
The ring stiffness of pipeline, becomes one new developing direction of structural walls pipeline, thus polytype UPVC composite pipe that has been born.
The problem that steel band reinforced polyethylene spiral ripple pipe is present is that equipment is made up of multiple stage extruder and steel strip forming machine,
Complex process and equipment manufacturing cost are expensive, can only produce in workshop, and because outer wall is ripple struction, trough does not have steel band to support, easily
Cracking damage, the bonding problem of expanding with heat and contract with cold that can not properly settle steel band and plastics between steel band and plastics, causes tube wall to be opened in addition
Split, occur in that a large amount of qualitative problems of construction.
It is welding between steel band enhanced polyethylene two flat walls spiral winding pipe strip, heat seal strength is difficult to ensure that steel band lays
In larger cavity, sealing is difficult, once water inlet causes whole piece steel band to corrode, loses bearing capacity.
The plastic-steel spirally-wound pipe of external V-arrangement or U-shaped steel rib, invar rib are that split is combined with plastic strap, and steel rib is in body
Outside, the problem for existing are that steel rib is perishable, and steel rib is easily disengaged with plastic strap, and the safety of pipeline is constituted a threat to.
102200205 B of patent CN discloses " U-PVC steel strip winding pipes and preparation method thereof ", and in the technology, steel band is
ㄇ types, in larger die cavity, seal by another cover plate, therefore can not solve the sealing of steel band well and corrosion-resistant ask
Topic, once same die cavity water inlet causes whole piece steel band to corrode, loses bearing capacity, and the intensity effect of upper cover plate is received in the fixation of steel band
It is larger, it is easily raised to cause pipe outer wall out-of-flatness, in its preparation method, also need to carry out heat treated to being wound in the pipeline after pipe.
In existing plastic-steel-wound Manifold technology, plastic strap mostly is polyethylene, and its Forming Quality and material hardness are not so good as
Between RPVC, therefore band, connection can only take the mode of the polyethylene material welding of melting, be difficult to implement male and female lock
The connected mode of button interlocking, the condition of produced on-site are good not as RPVC.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of two flat walls plastic-steel spirally-wound pipe, this two flat walls plastic-steel-wound
Pipe can solve fixation, the corrosion-resistant problem of pipe structure and steel band, solve the problems, such as the intensity and produced on-site of large diameter pipeline, make
Pipeline processing production is more simple, makes that pipeline globality is strong, ring stiffness is high, material-saving, reduces cost.
The two flat walls plastic-steel spirally-wound pipe of the present invention, is the double fastener strips by both sides with male and female lock and steel band
The structural walls monolayer of spiral winding and double-skin duct.The both sides with male and female lock double fastener strips, be by
Expressing technique quantity-produced strip irregular belt material, its cross sectional shape is hollow, square hole, interior muscle is I-shaped structure, thicker
The lateral connection muscle that plate divides in carrying, the lateral connection muscle that thin-walled part band divides without in, strip inwall one end locking device and a female embedding under having,
The other end has the faying surface of elongation, the projection for having fixed steel band on the inside of faying surface, and there is the public affairs lock towards outer wall faying surface end
Button, male locking device root are oblong-shaped, and top is that the lower arc-shaped of upper point or hemispherical or triangle or calabash shaped are raised, the public affairs,
Locking device and a female matches mutually, plays the overlap joint to inside pipe wall and sealing function in tubulation；Strip outer wall has, direction corresponding to inwall
Contrary male and female buckle structure, plays the overlap joint to pipe outer wall and sealing function in tubulation；After double fastener strip snappings
More than the plate width a values between strip two side, after strip spiral winding snapping, Vertical Steel band is embedded in plate to effective width b value
In the cavity formed with overlap joint, the centre distance of male and female lock is equal to the effective width of strip.
One double fastener strips are wound by wrapping machine continuous helical, and the body of the plastic construction of formation is two flat walls modeling
Pipe material, after adding Vertical Steel band, that is, forms two flat walls plastic-steel spirally-wound pipe.
During production double-skin duct, using 2835756 technologies of CN disclosed in inventor herein, by two double fastener plates
Band and two steel bands are simultaneously wound makes, every layer of tube wall is all inlaid with Vertical Steel band in overlap joint cavity, passes through gluing between strip
Agent bonding is integrally formed, and solves the problems, such as the ring stiffness of large diameter pipeline.
Produced on-site is by the double fastener strips of plate-like or shaft-like up to hundreds of rice or thousands of meters, plate-like steel band, tubulation
Job site is transported to wrapping machine, you can produce the two flat walls plastic-steel spirally-wound pipe that length is up to tens of meters.
The invention has the beneficial effects as follows：According to the two flat walls plastic-steel spirally-wound pipe that the invention described above is provided, by plastic strap
Between male and female lock chimeric snapping, the steel band tightly vertical plastic board/belt that is wrapped in is overlapped in the cavity to be formed, steel is solved
The corrosion-resistant problem of band, solves steel and linear expansion coefficient of plastics differs caused problem of Cracking, makes steel band to pipeline strength
Contribution perform to maximum, the ring stiffness of pipeline can reach 12.5KN/m2Even more high, is easily worked, can with produced on-site,
Manufacturing cost, cost of transportation can be greatly lowered.
