In the present embodiment; Annular connects steel band 22a and the structure that adopts connecting plate 22d to connect that is connected of being responsible for 21 intercepted winding steel 21b; Be about to be responsible for the many intercepting parts in 21 intercepted winding steel 21b ends; Correspond respectively to and be responsible for the size that connecting plate 22d is confirmed in 21 intercepted winding steel 21b ends; Guarantee that connecting plate 22d one side pastes (replacing being responsible for 21 intercepted winding steel 21b ends pastes with the plastic cement pipe 23a outer wall of arm 23 mutually), a side mutually and be connected steel band 22a downside with annular and dock connection, a side and be connected with the butt-end of the person in charge 21 intercepted winding steel 21b or overlap connection with the plastic cement pipe 23a outer wall of arm 23; This structure adopts connecting plate 22d as transition, can guarantee that connecting plate 22d is connected steel band 22a downside with annular and well docks connection.In other embodiments; Being responsible for 21 intercepted winding steel 21b ends pastes with the plastic cement pipe 23a outer wall of arm 23 mutually; The arcuate surface of side contacts, winding steel 21b is welded to connect with the filling of welding material with the annular gap that is connected steel band 22a downside on annular connection steel band 22a downside and the person in charge's 21 intercepted winding steel 21b front ends, also can realize the object of the invention.
Plastic-steel spirally-wound three-way pipe embodiment two
Plastic-steel spirally-wound three-way pipe 2 of the present invention comprises that plastic-steel twines the person in charge 21, plastic-steel twines arm 23 and link 22c.
Plastic-steel twines the person in charge's 21 outer walls at its plastic cement pipe 21a and is provided with spiral winding steel 21b; Plastic-steel twines arm 23 and is provided with spiral winding steel 23b at the outer wall of its plastic cement pipe 23a; Connection is passed through mutually with the sidewall of the person in charge 21 plastic cement pipe 21a in the end of the plastic cement pipe 23a of arm 23, and the axis of arm 23 is positioned at the horizontal direction of the person in charge 21 axis.
The spiral winding steel 23b of arm 23 is continuous along its helix.
Paste with the outer wall of arm plastic cement pipe 23a mutually the end of the person in charge's winding steel 21b that is blocked by the outer wall of arm plastic cement pipe 23a.
Link one side is pasted with the outer wall of arm plastic cement pipe 23a mutually, an end is corresponding be responsible for intercepted winding steel butt joint or overlap joint is connected, the other end connects adjacent arm winding steel 23b along the vertical direction of being responsible for intercepted winding steel 21b.
When intercepted person in charge's winding steel 21b and adjacent arm winding steel 23b in abutting connection with the time, the arm winding steel 23b that this intercepted person in charge's winding steel 21b is adjacent with this directly is connected.
The end that arm winding steel 23b is cut can be connected, also can not connect with person in charge's winding steel 21b that it intersects, all can realize the object of the invention.
Plastic-steel spirally-wound three-way pipe embodiment three
Present embodiment and embodiment two are basic identical; Difference is: many auxiliary steel bands that connect are set, and every auxiliary connects that steel band inboardly pastes with the outer wall of arm plastic cement pipe 23a mutually, two ends are connected with the adjacently situated surfaces (being adjacent two link 22c two opposite surfaces or immediate two side surfaces) of adjacent two link 22c respectively or two ends are connected with the adjacently situated surfaces of the adjacent person in charge two intercepted winding steel 21b respectively.
Many Stress Transfer chains of assisting the connection steel band to constitute the link 22c horizontal direction of this auxiliary connection steel band connection in proper order maybe are somebody's turn to do the Stress Transfer chain of assisting the person in charge's winding steel 21b horizontal direction that connects the steel band connection.
Many the auxiliary steel bands that connect can not seal along the ring seal of arm plastic cement pipe 23a outer wall yet, all can realize the object of the invention.
In the foregoing description, " connection " between the structure can be adopted to include but not limited to weld or Placement that bonding etc. is fit to.
In the foregoing description, link 22c can adopt platy structure, also can adopt block structure.
In the foregoing description,, annular surperficial at link connects steel strip surface, the auxiliary steel strip surface that connects is provided with protective layer, like paints and lacquers protection layer or plastic cement protective layer etc., connects steel band, the auxiliary anti-corrosion capacity that connects steel band with raising link, annular.Protective layer can cover or local link, annular connection steel band, the auxiliary bare metallic surface that connects steel band of covering fully.
Make the method for plastic-steel spirally-wound three-way pipe of the present invention, comprise the steps:
Material preparation step: the plastic-steel spirally-wound three-way pipe that promptly preparing draws up makes requires the plastic-steel of specification to twine the person in charge, plastic-steel winding arm and link material.
Look for point, setting-out, cutting step:
Like Fig. 3,4, shown in 5; According to the theoretical intersecting line of being responsible for plastic cement pipe outer wall and arm plastic cement pipe outer wall (on person in charge's plastic cement pipe outer wall, be 211, on arm plastic cement pipe outer wall, be 231); Confirm that two pipe outer walls pass through crossing peak (like the point of the H among Fig. 5) and minimum point (like the point of the B among Fig. 5) mutually; Between peak and minimum point, get a little at interval; Confirm that according to projection relation each point is responsible for coordinate and the coordinate on the arm plastic cement pipe 23a outer wall on the plastic cement 21a outer wall; Look for a little on person in charge's plastic cement pipe 21a outer wall and arm plastic cement pipe 23a outer wall according to determined coordinate, the smooth connection each point obtains being responsible for plastic cement pipe outer wall intersecting line 211 and arm plastic cement pipe outer wall intersecting line 231.
As shown in Figure 4; With the each point on the intersecting line 231 of arm plastic cement pipe 23a outer wall be responsible in arm plastic cement pipe 23a outer wall upper edge radially respectively translation be responsible for the distance that winding steel 21b exposes a height being responsible for plastic cement pipe 21a outer wall, the each point after the smooth connection translation obtains the winding steel intersecting line 221 of arm.
Mutually passing through intersection location with the person in charge with arm according to being responsible for length, is that basic point confirms to be responsible for the two ends port position respectively along being responsible for axial direction with the minimum point.According to a length of tube, be that basic point is confirmed arm flush end mouth position along a tube axis direction with the minimum point.
Theoretical intersection according to the both side surface of being responsible for winding steel 21b and arm plastic cement pipe 23a outer wall intersection; Confirm to be responsible for winding steel 21b is cut place's both side surface by arm plastic cement pipe 23a outer wall minimum point coordinate and peak coordinate respectively; On person in charge's winding steel 21b, looked for a little by section minimum point coordinate of place's both side surface and peak coordinate according to being responsible for winding steel 21b, and connect the intersection that obtains being responsible for winding steel 21b and arm plastic cement pipe 23a outer wall.
Cut person in charge plastic cement pipe 21a and intercepted person in charge's winding steel 21b thereof along being responsible for plastic cement pipe outer wall intersecting line 211 respectively with intersection; Along arm plastic cement pipe outer wall intersecting line 231 cutting arm plastic cement pipe 23a; Winding steel intersecting line 221 and arm radial cuts arm winding steel 23b along arm; Remove two ends by the arm winding steel that cuts, cutting is responsible for and arm flush end mouth.
