Abstract
The utility model discloses the effective band of a kind of plastic-steel-wound, be made up of base material, steel band and strengthened steel wire, base material is made up of level board and vertical plate, and its cross section is in " ⊥ " shape, the another symmetrical connecting plate in level board both sides, connecting plate upper surface separately establishes at least two projections respectively, between projection and projection and projection and level board side form groove, steel band is coated on level board inside, steel band cross section is oval row, its another uniform spherical groove in surface, vertical plate lower surface is connected with level board upper surface, and strengthened steel wire is coated on vertical plate inside.This new structure intensity is large, resistance to compression, resistance to tension are strong, curling tubing is convenient to bonding, and abutting edge structural stability linkage structure intensity is large, the tubing interface that it uses this band to prepare has the features such as easy to connect, interface join strength is large, connection sealing is good, thus contributes to the quality and the usability that improve tubing further.
Description
Technical field
Basis is novel relates to a kind of plastic-steel band, particularly relates to the effective band of a kind of plastic-steel-wound.
Background technique
Current plastic-steel spirally-wound pipe belongs to a kind of Reinforced by Metal plastic water supply and sewage pipe, its main structure is be made up of plastic basis material and the strengthening steel band that is coated on base material inside, it is when producing, then be wound around by the banding substrate being coated with strengthening steel band and formed through bonding, therefore the banding substrate being coated with strengthening steel band has then become the key factor determining plastic-steel spirally-wound pipe performance and quality, in order to improve quality and the structural strength of the banding substrate being covered with strengthening steel band, way conventional is at present the use amount increasing base material and strengthening steel band on the one hand, on the other hand select mechanical strength and the large strip material of toughness, although these two kinds of methods can have to belong to a certain extent improve plastic-steel spirally-wound pipe structural strength, but also increase deadweight and the cost of production of plastic-steel spirally-wound pipe, and presently used steel band and base material cross section mostly are rectangle, therefore in using and processing, very easily produce stress concentration phenomenon, thus cause matrix structure impaired, simultaneously easily cause carry out curling prepare tubing time, joint between band side is bonding seldom relatively large, and bonding after structural strength also relatively little, therefore plastic-steel spirally-wound pipe is easily caused to occur in abutting edge leaking or fracture, the also connection of Billy between two plastic-steel spirally-wound pipes simultaneously.
Summary of the invention
The utility model object is just to overcome above-mentioned deficiency, provides plastic-steel-wound effective band.
For achieving the above object, this is novel is be achieved through the following technical solutions:
The effective band of a kind of plastic-steel-wound, by base material, steel band and strengthened steel wire are formed, base material is made up of level board and vertical plate, and its cross section is in " ⊥ " shape, the another symmetrical connecting plate in level board both sides, connecting plate lower surface and level board lower surface are in same level, connecting plate upper surface separately establishes at least two projections respectively, between projection and projection and projection and level board side form groove, projection is consistent with groove shapes, its projection overall dimensions is maximum sized 0.7-1.3 times of groove, projection upper surface is separately low than level board upper surface 1-10 millimeters, steel band is coated on level board inside, its distance level board upper surface and lower surface distance are all not less than 1 millimeter, steel band cross section is oval row, its another uniform spherical groove in surface, vertical plate lower surface is connected with level board upper surface, strengthened steel wire is coated on vertical plate inside, strengthened steel wire and vertical plate upper surface distance are 1/5-1/3 of vertical plate total height, distance vertical plate bi-side minimum range is not less than 1 millimeter.
Projection and groove cross section are rectangle.
Vertical plate cross section is rectangle, trapezoidal or oval.
Strengthened steel wire cross section is circular or rectangle.
This new structure intensity is large, resistance to compression, resistance to tension are strong, curling tubing is convenient to bonding, and abutting edge structural stability linkage structure intensity is large, the tubing interface that it uses this band to prepare has the features such as easy to connect, interface join strength is large, connection sealing is good, thus contributes to the quality and the usability that improve tubing further.
Accompanying drawing explanation
Fig. 1 is this new structure schematic diagram;
Fig. 2 is steel band cross section structure schematic diagram.
Embodiment
As illustrated in fig. 1 and 2, the effective band of a kind of plastic-steel-wound, by base material 1, steel band 2 and strengthened steel wire 3 are formed, base material is made up of level board 101 and vertical plate 102, and its cross section is in " ⊥ " shape, the another symmetrical connecting plate 4 in level board 101 both sides, connecting plate 4 lower surface and level board 101 lower surface are in same level, connecting plate 4 upper surface separately establishes at least two projections 5 respectively, between projection 5 and projection 5 and projection 5 form groove 6 with level board 101 side, projection 5 is consistent with groove 6 shape, its projection 5 overall dimensions is maximum sized 0.7-1.3 times of groove 6, projection 5 upper surface is separately low 1-10 millimeters than level board 101 upper surface, it is inner that steel band 2 is coated on level board 101, its distance level board 101 upper surface and lower surface distance are all not less than 1 millimeter, steel band 2 cross section is oval row, its another uniform spherical groove 7 in surface, vertical plate 102 lower surface is connected with level board 101 upper surface, it is inner that strengthened steel wire 3 is coated on vertical plate 102, strengthened steel wire 3 is 1/5-1/3 of vertical plate 102 total height with vertical plate 102 upper surface distance, distance vertical plate 102 bi-side minimum range is not less than 1 millimeter.
This band in use, first heat, then band is at the uniform velocity being transported on winding boarding machine, utilize press fit device on it by material curve tubing circlewise, when carrying out band pressing, then front side band connecting plate upper protruding block must be engaged with the projection on rear side band connecting plate and groove with groove, after its engagement, carry out high-temperature laminating again; When needing to connect two tubing utilizing this band to be prepared from, first needing two tube opening place projections and groove to be connected with a joggle, then carrying out reinforcing and anti-drain process.
