Abstract
The utility model relates to a steel-plastic composite pipe connection structure of an upright reinforcing rib, and is characterized in that the connection structure comprises a fill-up plastic block (2) fusibly welded with the reinforcing rib and the surface of a pipe body into a whole, a thin-wall rubber sleeve (3) positioned on the outer side of the reinforcing rib and the fill-up plastic block (2), a foaming rubber plate (4) coated on the outer layer of the thin-wall rubber sleeve (3), and an outmost stainless steel plate strip (5). Pulling lugs and fastening bolts passing through the pulling lugs are welded and fixed at both ends of the stainless steel plate strip (5). The utility model overcomes the default that the stress generated at the pipe product connection position in the prior art is extremely easy to lead fillet weld between a spigot and a pipe product to cause the destroy of connection, and is of the connection structure which does not need any special processing to the pipe product when the pipe product is produced and has reliable connection performance, thereby not only ensuring that the production manufacturing of the pipe product is simple, but also ensuring that the operation of the pipe produce connection is simple.
Description
Technical field
The utility model relates to the connection of composite pipe, particularly has the connection of the steel-plastic composite pipe that the irregular belt material of vertical reinforcing rib twine to form.
Technical background
For the connection of plastic pipe, often according to the structural feature of the manufacture method of tubing and tube wall selected for use not only simply, but also reliable connection method.
For the double-wall corrugated drain pipe that adopts extrusion way to produce, owing to be convenient to make joint socket at pipe end, so adopted the connecting means of socket joint and rubber seal.For the pure heterotypic strip of moulding with extrusion way production, twine waste pipe through the hollow that winding is welded into, because its outer wall is smooth, so it has adopted shrink belt winding outsourcing, rubber ring to add multiple Placements such as stainless steel kink and Electric thermal smelting belt outsourcing melting welding.For the tubing that number of patent application is 2005100829114 (a kind of steel band reinforced plastic drainpipe and manufacturing method and apparatus thereof), because its pipe outer wall is a spirality vertical reinforcing rib structure, the outer surface out-of-flatness, can't adopt the connecting means of existing plastic tube to implement to connect, so its proposition is made socket with the plastics strip at pipe end, with round in the tubing, with the manual Placement of extruding the weldering field welding as natural bellmouth.But this Placement is made complicated difficulty first, and effect is low; Second site operation welding labor intensity is big, and weld strength is low.Because the length of expanding with heat and contract with cold changes, or because soil settlement, underground water buoyance lift cause tubing to be out of shape when mobile, the stress that produces in the tubing joint very easily makes the fillet weld between socket and the tubing be torn and causes continuous damage when tubing.At above-mentioned situation, the application has proposed to be specifically designed to the Placement of aforementioned tubes.
The model utility content
The purpose of this utility model is to propose need not carry out complicated special processing to tubing when tubing is made, and can guarantee that the tubing manufacturing is simple, and it is easy and simple to handle to guarantee that again tubing connects, the reliable linkage structure of switching performance.
For achieving the above object, the steel-plastic composite pipe connecting structure with vertical reinforcing rib that the utility model provides is that the jacket-type metal plate and belt clamps the rubber sleeve structure that is tightly connected.This linkage structure comprises with strengthening rib and body surface melting welding all-in-one-piece fills and leads up unit of plastic 2, be positioned at strengthening rib and fill and lead up the thin-walled rubber sleeve 3 in unit of plastic 2 outsides, be coated on thin-walled rubber sleeve 3 outer field bipeltate plates 4, outermost stainless steel sheet strip 5, the two ends of stainless steel sheet strip 5 are welded with La Er and pass the clamping bolt that draws ear.
This structure is applicable to the connection of small-bore steel-plastic composite pipe, both having of making connected the clamping connecting sleeve that draws ear and clamping bolt to constitute, the Placement that internal layer compensates with sealing of thin-walled rubber sleeve and the pressurization of bipeltate plate with stainless steel sheet strip at two pipe joint skins.In order to realize the sealing of above-mentioned connecting means, must cut off the spiral annular groove in the tubing join domain, stop medium to leak thus.Therefore in the join domain at every tubing two ends, do at least on each annular groove and fill and lead up the plastics shutoff that unit of plastic constitutes together.
Description of drawings
Describe the utility model in detail below in conjunction with accompanying drawing.
Fig. 1 is the steel-plastic composite pipe jacket-type metal plate and belt long splice composition with vertical reinforcing rib;
Fig. 2 is the viewgraph of cross-section with steel-plastic composite pipe jacket-type metal plate and belt linkage structure of vertical reinforcing rib;
Fig. 3 is that the plastics fill block is arranged schematic representation.
Embodiment
Fig. 1-3 shows two sections steel-plastic composite pipe jacket-type metal plate and belt linkage structure schematic representation with vertical reinforcing rib.It is in the outside of tubing two sections pipes to be fused that the jacket-type metal plate and belt connects.Jacket-type metal plate and belt linkage structure comprises with strengthening rib and body surface melting welding all-in-one-piece fills and leads up unit of plastic 2, be positioned at strengthening rib and fill and lead up the thin-walled rubber sleeve 3 in unit of plastic 2 outsides, be coated on thin-walled rubber sleeve 3 outer field bipeltate plates 4, outermost stainless steel sheet strip 5, the two ends of stainless steel sheet strip 5 are welded with La Er and pass the clamping bolt that draws ear.It is identical with the strengthening rib height to guarantee to fill and lead up unit of plastic end face and strengthening rib end face on same cylndrical surface wherein to fill and lead up the height of unit of plastic 2, fills and leads up unit of plastic 2 and plays the effect of fluid from leaking between strengthening rib that stop.After two tubing 1 butt joints, two pipe end covers are connected together with thin-walled rubber sleeve 3 at joint, the thickness of rubber sleeve 3, natural girth should guarantee can manually be enclosed within it on pipe and enough elasticity sex change are arranged, and can fit tightly with the strengthening rib cylindrical to contact.The material of thin-walled rubber sleeve 3 should guarantee that the medium of being carried is had good chemical stability.Use again with the bipeltate plate 4 of thin-walled rubber sleeve 3 wide, relative thicker (being not more than 10mm) at the skin of rubber sleeve 3 and to coat, the length of bipeltate plate 4 should guarantee that it can be fitted naturally and be coated on the outer back two of thin-walled rubber sleeve 3 and correct leaning on, and the good compression deformability is arranged.Outermost surface will be managed the joint with stainless steel sheet strip 5 and will be tightened to one, thereby reach the purpose that composite pipe connects sealing.Thin-wall stainless steel strip 5 can bend to circle by manpower by hand, also can be made of (being used for heavy caliber pipe connects) isometric two sections.Be welded with at place, the two ends of stainless steel sheet strip 5 and draw ear, manually with its flex housing going here and there bolt on the ear drawing behind the pipe end, adjust its clamping force on circumference by elasticity bolt.In above-mentioned jacket-type stainless steel sheet strip linkage structure, thin-walled rubber sleeve that internal layer the is used 3 main seal actions that rise the joint, and bipeltate plate 4 plays stainless clamping force evenly is applied to effect on the rubber sleeve 3.Under the situation that stainless steel sheet strip 5 clamps, bipeltate plate 4 can produce bigger resiliently deformable, tubing exist oval, strengthening rib just exist deviation situation under, this resiliently deformable can compensate it effectively, thereby guarantees the sealing that the metal reinforced plastic waste pipe connects.
