Abstract
The plastic strip for winding the pipe is provided with skillful strip edges (1, 2) which are provided with two ribs (5, 6) and grooves (7, 8) which extend out in parallel, the width of the outer groove (7) is larger than the thickness of the inner rib (6), and joints formed by the ribs (5, 6) and the grooves (7, 8) are completely within the thickness of the strip.
Description
The present invention relates to produce the plastics bandage of spiral wound pipe, connection rib is arranged on it, the head of rib enlarges; And extend on fluted limit along this band in some areas at least, and adjacent bandage limit is coupled together, and rib and groove at two lace places design very ingeniously mutually.
With above-mentioned the sort of plastics bandage production coiling pipe is known.The connection that forms at adjacent strip band edge place with one deck or two-layer section bar or band is the weak part of this pipe.This problem can become hazards, and especially pipe uses under pressure or be buried in underground situation.
Snap joint between the two above-mentioned adjacent lace is suitable for the special elastic band, therefore is particularly suitable for producing the insulation tube of existing pipeline or cable.Stressed when big the bonding pad also wrap other protective layer or band usually.
The purpose of this invention is to provide a kind of plastics bandage of producing above-mentioned spiral wound pipe, it makes the joint of lace centre under various situation not there be joint with the structure of simple cheap.
According to the present invention, a kind of plastics bandage of producing the spiral wound pipe is provided, its connection rib has the head of increasing, the groove that the excision bottom is arranged along band boundaries, the rib of this groove and adjacent ribbons is worked in coordination, it is characterized in that, two parallel rib and grooves are arranged on each lace, wherein, inboard groove conforms to the cross section of cross section with the lace external fin, and separately second rib thickness that is internal-rib less than the outer well width that forms in the middle of the both sides of the chest of a band, therefore, when lace connected, being positioned at two inboard ribs can be in the clear mutually towards a direction generation strain when head sticks into groove.
Particularly, the rib of outer lace has a front, it be from strip face inwards skew back cut and form.
Particularly, become the rib of joint and groove in its length of lace place all within the thickness range at this band.
Particularly, described bandage in some areas be hollow to form the double walled bandage.
Particularly, the elastomeric seal part be positioned at rib head or in conjunction with the time relative position groove on.
Particularly, water jacket is that the side by two ribs forms, and the head of internal-rib is stretched out in a side that the side is an internal-rib of inside groove on this side.
Core of the present invention is to have the design of the syndeton of internal-rib, this internal-rib resilient movement freely in the quick-make process, and rib can be arranged in there is not what problem within the beam thickness.This joint also is particularly suitable for the pipe that coiling is subjected to inside and outside high pressure.
Hereinafter illustrated embodiment elaborates to the present invention with reference to the accompanying drawings, and these accompanying drawings are:
Fig. 1 is the cross section according to the plastic strip of the present invention's structure.
Fig. 2 is the sectional view of two adjacent lace bonding pads (joint).
Fig. 3 is the strip edge enlarged drawing.
Fig. 1 has described the cross section of plastic strip.
The lace 1,2 that has linked good two adjacent ingenious designs when Fig. 2 illustrates the pipe coiling.This two lace 1,2 is two parallel edges of a plastic tape, and the edge designs of band is ingenious and link with the snap joint form and to be used to form pipe.
Fig. 3 shows the structure for amplifying (second band edge 2 is the minute surface symmetry on its left side) of a lace 1.
This ribbon structure is hollow type, i.e. double wall band, and it is with 3 and 4 two layers, is characterized in that thickness is 12～15mm. External fin 5,6 and interior water jacket 7,8 in the strip edge place forms.9 of fronts slightly tilt to stretch out (wedge-shaped surface) from strip face 10 inwards, and the border 8 of groove ' design is also very ingenious, be close to gradually when making the front 9 of lace ' with its binding surperficial 8 '.
Groove 7 is opened side 5 at rib ' and 6 ' centre, second groove 8 is then in groove side 6 " and 8 ' centre, surface.
The cross section of groove 8 meets the cross section (having only very little gap) of continuous band external fin basically.
But groove 7 differences, it must hold the lace internal-rib that links with it, and width is far longer than the thickness (see figure 1) of the rib that is held.
When two lace 1,2 link, to imbed in the process of groove 8 at the head of rib 6, internal-rib generation elastic bending can be returned to the normal position again later on.
Can know that from figure the head of seeing rib 5,6 widens towards a side 5 , 6 of groove 7,8, they are obeyient ground fluid-tight engagement in engaging process, and in other words, rib 5,6 becomes the incision of groove 7,8.
As shown in Figure 1, can expect on head of rib 5 , 6 or directly relative with it bottom land, have elastomeric sealing projection 11,12 to be tightly connected with formation.
Claims (6)
1. produce the plastics bandage of spiral wound pipe, its connection rib has the head of increasing, the groove that the excision bottom is arranged along band boundaries, the rib of this groove and adjacent ribbons is worked in coordination, it is characterized in that, two parallel rib and grooves are arranged on each lace, wherein, inboard groove conforms to the cross section of cross section with the lace external fin, and separately second rib thickness that is internal-rib less than the outer well width that forms in the middle of the both sides of the chest of a band, therefore, when lace connected, being positioned at two inboard ribs can be in the clear mutually towards a direction generation strain when head sticks into groove.
2. plastics bandage according to claim 1 is characterized in that the rib of outer lace has a front, it be from strip face inwards skew back cut and form.
3. plastics bandage according to claim 1 and 2 is characterized in that, becomes the rib of joint and groove in its length of lace place all within the thickness range at this band.
4. plastics bandage according to claim 1 is characterized in that, described bandage in some areas be hollow to form the double walled bandage.
5. plastics bandage according to claim 1 is characterized in that, the elastomeric seal part be positioned at rib head or in conjunction with the time relative position groove on.
6. plastics bandage according to claim 1 is characterized in that, water jacket is that the side by two ribs forms, and the head of internal-rib is stretched out in a side that the side is an internal-rib of inside groove on this side.
