Description

  The present invention relates to a band-shaped member bundle and a manufacturing method thereof.

  Conventionally, in order to rehabilitate existing pipes such as sewage pipes, water pipes, agricultural water pipes, gas pipes, etc., strip members with joints formed on both side edges are drawn into the existing pipes in a spiral shape. It has been proposed and practiced to produce a spiral tube by winding and joining the joining portions of adjacent strip members.

  The belt-shaped member used for the production of the spiral tube is hollow at the factory by winding a set winding length around the drum capable of expanding and reducing the diameter of the winding device or around the detachable winding core of the manufacturing drum. After forming the cylindrical band-shaped member, a plurality of binding materials are wound around the inner circumferential surface, the outer peripheral surface, and the left and right side surfaces of the hollow cylindrical band-shaped member and wound together to bind the band-shaped member bundle. Formed. The band-shaped member bundle is transported to the construction site, and the band-shaped member bundle is housed and fixed in the construction jig supported on the turntable at the construction site, and then the binding is released to perform the construction treatment. The tool is rotated on a turntable, and the belt-like member is pulled out from the rotating hollow cylindrical belt-like member and used for making a spiral tube (for example, see Patent Document 1).

  Further, when the belt-like member is wound around the hollow cylindrical belt-like member, the outermost layer is based on the width and height of the belt-like member, the winding length of the belt-like member, the width and inner diameter of the band-like member bundle, and the winding pitch of the belt-like member. It has also been proposed to wrap the belt-like member over the entire width in the width direction of the belt-like member bundle to prevent collapse of the belt-like member bundle (for example, see Patent Document 2).

  As shown in FIG. 6, the belt-like member 100 is formed by extrusion molding a flexible synthetic resin, for example, hard vinyl chloride, and has a T-shaped cross section on the back surface of the belt-like substrate 101. A plurality of reinforcing ribs 102 are erected vertically with respect to the substrate 101, a joint convex portion 103 is erected on one side edge of the substrate 101, and a joint convex portion 103 is provided on the other side edge. A stepped portion 104 stepped down to the back side by the thickness of the substrate 101 is formed so that the side edge portion of the substrate 101 is disposed, and the joint protrusion 103 can be fitted into the stepped portion 104. A recessed portion 105 is provided, and inclined ribs 106 are formed in the bonded recessed portion 105 so as to be positioned on the protruding side of the bonded recessed portion 105 as the distance from the substrate 101 increases.

  However, the above-described band-shaped member bundle is manufactured on the premise of a construction jig. That is, depending on the mode of the pipe manufacturing apparatus for manufacturing the spiral pipe, it is necessary to draw the band-shaped member from the inner peripheral side of the hollow cylindrical band-shaped member and supply it to the pipe manufacturing apparatus in a spiral shape. In this case, it is necessary to rotate the hollow cylindrical belt-shaped member so as to supply the belt-shaped member without excess or deficiency in response to the production of the helical tube by the pipe production apparatus. For this reason, after assembling the construction jig and supporting it on the turntable at the construction site, drop the band-shaped member bundle into the assembled construction jig using a crane-equipped truck, etc. The band-shaped member bundle is fixed, and the hollow cylindrical band-shaped member is rotated on the turntable via a construction jig. As a result, there has been a drawback that the work becomes complicated, such as assembling the construction jig or dropping the band-shaped member bundle into the assembled construction jig. Further, it is necessary to secure an assembly work space for the construction jig on the road or the like in addition to the storage place for the band-shaped member bundle.

Thus, a tubular body is formed over the entire width of the hollow cylindrical belt-shaped member.

  According to the present invention, the outermost belt-like member of the hollow cylindrical belt-like member formed by spirally winding the belt-like members joins the joining portions of the belt-like members adjacent to each other over the entire width of the hollow cylindrical belt-like member. And formed into a tubular body. Therefore, if the binding of the band-shaped member bundle is released, a hollow cylindrical band-shaped member having the outermost layer formed in the tubular body can be obtained.

  As a result, if the band-shaped member bundle is directly mounted on the turntable and the binding is released, the hollow cylindrical band-shaped member can be rotated via the tubular body, so that it can be rotated without using a construction jig. The belt-like member can be drawn out from the inner peripheral side and used for making a spiral tube. Further, it is possible to reliably prevent the strip-shaped member from being unwound and store and transport it.

  The method for producing a band-shaped member bundle according to the present invention comprises winding a band-shaped member having joints formed on the left and right side edges around a drum that can be reduced in diameter or around a removable core. In the manufacturing method for manufacturing a band-shaped member bundle by binding the left and right side surfaces, the inner peripheral surface, and the outer peripheral surface of the stacked hollow cylindrical band-shaped members with a plurality of binding materials wound at intervals in the circumferential direction. Is wound into a hollow cylindrical shape, and then joined to the outer peripheral surface of the adjacent strip-shaped members directly or via a bonding material to join the tubular body over the entire width of the hollow cylindrical strip-shaped member. It is characterized by forming.

  According to the present invention, a belt-like member having joints formed on the left and right side edges is wound around a drum or a winding core, and then wound into a hollow cylindrical shape having a set winding length. When winding the belt-shaped member, the joint portions of the belt-shaped members adjacent to each other are bonded directly or via a bonding material to form a tubular body over the entire width of the hollow cylindrical belt-shaped portion.

  As a result, the strip-shaped member can be securely stored, transported, and can be transported, and if the binding is released, the strip-shaped member that can be rotated on the turntable via the tubular body becomes a strip-shaped member. The member bundle can be easily manufactured.

  According to the band-shaped member bundle of the present invention, when the binding is released, the band-shaped member can be pulled out from the inner peripheral side by rotating on the turntable without using a construction jig. Further, it is possible to reliably prevent the strip-shaped member from being unwound and store and transport it.

  Moreover, according to the manufacturing method of the band-shaped member bundle of the present invention, the belt-shaped member can be reliably prevented from being stored and transported, and if the binding is released, the construction jig can be used. It is possible to easily manufacture a band-shaped member bundle that can be rotated on the turntable and pulled out from the inner peripheral side.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  1 and 2 show an embodiment of the band-shaped member bundle 1 of the present invention.

  As described in Patent Document 1 described above, the band-shaped member bundle 1 is manufactured using a winding device having a drum capable of expanding and reducing the diameter, or a manufacturing drum having a detachable winding core. The Specifically, after forming the hollow cylindrical belt-like member 10 by winding the belt-like member 100 around the drum of the winding device or the core of the production drum, the outer peripheral surface and inner peripheral surface of the hollow cylindrical belt-shaped member 10 are formed. In addition, the cushioning material 2 such as cardboard is wound around the cushioning material 2 around the cushioning material 2 around the cushioning material 2 while winding the cushioning material 2 such as corrugated cardboard at a plurality of locations at intervals in the circumferential direction. It is manufactured by winding and binding the binding material 3 such as.

  Here, the hollow cylindrical band-shaped member 10 of the band-shaped member bundle 1 includes a hollow cylindrical band-shaped member main body 10A formed by winding a set winding length, and an outer peripheral surface of the hollow cylindrical band-shaped main body 10A. It is comprised from the tubular body 10B formed of the strip | belt-shaped member 100 of the outermost layer wound around. That is, the outermost band member 100 is formed in the tubular body 10B by bonding the joint portions 103 and 105 of the band members 100 and 100 adjacent to each other over the entire width of the hollow cylindrical band member 10. Thereby, the hollow cylindrical strip-shaped member 10 has a structure in which the tubular body 10B covers the outer peripheral surface of the hollow cylindrical strip-shaped member main body 10A formed by being wound over the set winding length.

  The manufactured band-shaped member bundle 1 is covered with an ultraviolet deterioration preventing sheet 4 on the outer peripheral surface, the inner peripheral surface, and the left and right side surfaces, and the band-shaped member 100 is deteriorated by ultraviolet rays when stored on a pallet. To prevent it.

  Next, the case where such a strip | belt-shaped member binding body 1 is manufactured using the winding device 5 is demonstrated.

  In addition, the winding apparatus 5 is conventionally well-known as described in patent document 1, and the detailed description is abbreviate | omitted.

  Prior to the description of the manufacturing method of the band-shaped member bundle 1, the pressing roller 6 disposed so as to be capable of moving forward and backward facing the winding device 5 will be described with reference to FIG. 4.

  The pressure roller 6 is configured to rotatably support a primary pressure roller 61 and a secondary pressure roller 62, respectively. The primary pressure roller 61 includes a fitting roller 611 and a plurality of guide rollers 612. .

  The fitting roller 611 is configured to rotate in contact with the top of the joint recess 105 of the subsequent band member 100 in the preceding band member 100 and the subsequent band member 100 wound spirally adjacent to each other. The outer diameter is set such that the distance between the outer peripheral surface of the fitting roller 611 and the top of the reinforcing rib 102 of the inner layer side band member 100 corresponds to the height of the band member 100. In addition, the guide roller 612 is formed to have a larger diameter than the fitting roller 611 and is configured to rotate while being substantially in contact with the back surface of the substrate 101 between the adjacent reinforcing ribs 102 and 102 of each strip member 100. The outer diameter is set so that the distance between the outer peripheral surface of the guide roller 612 and the top of the reinforcing rib 102 of the inner layer side band member 100 substantially corresponds to the thickness of the substrate 101 of the band member 100.

  On the other hand, the secondary pressing roller 62 includes a locking roller 621 and a plurality of guide rollers 622.

  The locking roller 621 is spirally wound adjacent to each other, and the adjacent belt-like members 100 and 100 (tubular) in which the joining concave portion 105 of the belt-like member 100 following the joining convex portion 103 of the preceding belt-like member 100 is fitted. The body 10B) is configured to rotate in contact with the inclined rib 106 of the subsequent strip member 100. That is, the locking roller 621 pushes the inclined rib 106 of the subsequent belt-like member 100 from the outer peripheral side toward the preceding belt-like member 100 to be elastically deformed, and locks it to the reinforcing rib 102 of the preceding belt-like member 100. Further, the guide roller 622 is configured to rotate between the adjacent reinforcing ribs 102 of each belt-like member 100 so as to substantially contact with the back surface of the substrate 101, and the outer circumferential surface of the guide roller 622 and the inner-layer side belt-like member 100. The outer diameter is set so that the distance from the top of the reinforcing rib 102 corresponds to the thickness of the substrate 101 of the strip member 100.

  Hereinafter, a procedure for winding the belt-shaped member 100 using the winding device 5 and manufacturing the belt-shaped member bundle 1 will be described.

  The drum 51 (see FIG. 4) having an enlarged diameter of the winding device 5 installed facing the forming line of the belt-like member 100 is rotated and moved in the left-right direction in synchronization with the rotation, and one end of the drum 51 is stopped. The worn belt-like member 100 is wound in order in a spiral manner, and wound around a set winding length to form a hollow cylindrical belt-like member body 10A having a length used for making a spiral tube.

  Here, when the set winding length is wound, the width and height of the belt-shaped member 100 so that the belt-shaped member 100 of the final layer of the hollow cylindrical belt-shaped member main body 10A is aligned over the entire width of the drum 51, The band-shaped member 100 is wound up based on the winding length, the width and inner diameter of the band-shaped member bundle 1, and the winding pitch of the band-shaped member 100.

  In this manner, when the belt-like member 100 having the set winding length is wound while being traversed over the entire width of the drum 51 to form the hollow cylindrical belt-like member body 10A, the outermost belt-like member 100 is formed on the outer peripheral surface thereof. Further roll up. That is, when the belt-like member 100 is wound so as to be adjacent to each other on the outer peripheral surface of the hollow cylindrical belt-like member main body 10A, the belt-like member 100 following the joining convex portion 103 of the preceding belt-like member 100 as shown in FIG. The drum 51 is rotated by setting the winding pitch so that the bonding recess 105 faces, and is moved in the left-right direction in synchronization with the rotation. Moreover, the pressing roller 6 is advanced with respect to the winding device 5 to press the adjacent belt member 100 and the succeeding belt member 100 adjacent to each other in the outermost layer (see FIG. 4).

  Thus, when the drum 51 rotates and moves in the left-right direction, when the outermost belt-like member 100 is wound up and made one turn, the belt-like member 100 that follows the joining convex portion 103 of the preceding belt-like member 100 is wound. Are opposed so as to be fitted from the outer peripheral side. Here, the subsequent strip member 100 is pressed in contact with the primary pressing roller 61 of the pressing roller 6 and joined to the preceding strip member 100 adjacent to each other. That is, the top of the joining concave portion 105 of the subsequent belt-like member 100 is pressed by the fitting roller 611 of the primary pressing roller 61 and is fitted into the joining convex portion 103 of the preceding belt-like member 100, so that the joint portions 103 and 105 are joined. The tubular body 10B is manufactured by the adjacent strip-shaped members 100, 100. Further, the guide roller 612 is disposed between the reinforcing ribs 102 and 102 of the adjacent belt-like members 100 and 100 to restrict the movement in the left-right direction.

  On the other hand, the adjacent belt-like members 100 and 100 to which the joint portions 103 and 105 are joined by the primary pressing roller 61, i.e., the tubular body 10 </ b> B, are wound around the drum 51 to the downstream side of the primary pressing roller 61. It moves and comes into contact with the secondary pressing roller 62 and is pressed. That is, the inclined rib 106 of the subsequent strip-shaped member 100 forming the tubular body 10B is pressed by the locking roller 621 of the secondary pressing roller 62, elastically deformed, and locked to the reinforcing rib 102 of the preceding strip-shaped member 100. . Further, the guide roller 622 is disposed between the reinforcing ribs 102 and 102 of the adjacent belt-like members 100 and 100 and restricts the movement in the left-right direction.

  Hereinafter, similarly, the drum 51 rotates and moves in the left-right direction in synchronization with the rotation, so that the belt-shaped member that precedes the joining concave portion 105 of the belt-shaped member 100 that follows the entire width of the drum 51 via the pressing roller 6. In addition, the tubular rib 10B is formed over the entire width of the drum 51 by engaging the joint rib 103 of the belt 100 with the inclined rib 106 of the belt member 100 and the reinforcing rib 102 of the belt member 100.

  If the tubular body 10B extending over the entire width of the drum 51 is manufactured by the outermost belt member 100, the winding device 5 is stopped, the belt member 100 is cut, and then the cutting end is used with a rope or the like. Then, the drum 51 is temporarily fixed.

  In this case, when the strip member 100 is cut, it is cut along the left and right side surfaces of the hollow cylindrical strip member 10, and the joining state of the preceding strip member 100 and the subsequent strip member 100 is determined as the hollow cylindrical strip member 10. To the left and right edges. As a result, the adjacent strip members 100, 100 are joined to the joints 103, 105 up to the tip of the cut strip member 100, and even if an unexpected external force is applied, it is difficult to come off.

  If the hollow cylindrical belt-like member 10 in which the outermost belt-like member 100 is formed in the tubular body 10B is formed, the shock-absorbing material 2 is wound around the outer peripheral surface, the left and right side surfaces, and the inner peripheral surface. The binding material 3 is wound around 2 and tightened to bind. Thereafter, the drum 51 is rotated by a set angle to wind the shock absorbing material 2, and the binding material 3 is wound around the shock absorbing material 2 and tightened and bound repeatedly.

  Then, when the binding with the binding material 3 is completed, that is, when the band-shaped member binding body 1 is manufactured, the UV deterioration preventing sheet 4 is spread over the outer peripheral surface, the left and right side surfaces, and the inner peripheral surface of the band-shaped member binding body 1. After the mounting, the drum 51 is moved to a predetermined position, the diameter of the drum 51 is reduced and mounted on a lifter (not shown), and the drum 51 is moved and extracted from the hollow portion of the band-shaped member bundle 1. On the other hand, the band-shaped member bundle 1 supported by the lifter is supported and stored on a pallet (not shown) in a state where the periphery is covered by the ultraviolet ray deterioration prevention sheet 4.

  On the other hand, when producing a spiral tube using such a band-shaped member bundle 1, the band-shaped member bundle 1 stored on the pallet is transported to the construction site and directly on the turntable 7 (see FIG. 5). To place. Subsequently, after taking out the inner peripheral side part of the ultraviolet degradation prevention sheet 4, the binding material 3 is cut | disconnected and the fixation of the direction which cross | intersects the winding direction of the strip | belt-shaped member 100 is cancelled | released. When the binding of the strip-shaped member bundle 1 is released, as shown in FIG. 5, the hollow cylindrical strip-shaped member body 10A formed by winding the strip-shaped member 100 having a set winding length and the outer peripheral surface thereof are covered. The hollow cylindrical belt-like member 10 made of the tubular body 10B made by the outer belt-like member 100 is mounted on the turntable 7 with the outer peripheral surface and the left and right side surfaces thereof being shielded from light by the ultraviolet ray deterioration preventing sheet 4. . Thereby, the winding start end part of the strip-shaped member 100 can be pulled out from the inner peripheral side of the hollow cylindrical strip-shaped member 10 and supplied through a manhole (not shown).

  In this case, the hollow cylindrical belt-like member 10 can rotate smoothly on the turntable 7 by forming the outermost belt-like member 100 on the turntable 7 by forming the tubular member 10B on the tubular body 10B. Moreover, the belt-like member 100 is pulled out from the inner peripheral side of the hollow cylindrical belt-like member 10, so that the hollow cylindrical belt-like member 10 maintains its outer diameter, that is, the tubular body 10 B to the end and is on the turntable 7. Supported by Therefore, the belt-like member 100 can be pulled out from the inner peripheral side of the hollow cylindrical belt-like member 10 to the end without any trouble.

  As a result, at the construction site, the hollow cylindrical belt-like member 10 can be rotated by being supported by the turntable 7 via the tubular body 10B, and is used as a helical tube for rehabilitating the existing pipe. As well as disassembling and assembling the tools, operations such as dropping the band-shaped member bundle 1 can be omitted, and workability can be greatly improved when a spiral tube that consumes a large number of band-shaped members 1 is manufactured. it can. Further, the strip-like member 100 can be stored and transported while being reliably prevented from being unwound.

  By the way, in embodiment mentioned above, although the strip | belt-shaped member 100 which each formed the junction convex part 103 and the junction recessed part 105 in the right-and-left side edge part was wound up in order and bound, the case where the strip | belt-shaped member binding body 1 was manufactured was illustrated. However, the present invention is not limited to such a belt-like member 100.

  For example, as shown in FIG. 10, the band-shaped member bundle 1 (see FIG. 7) can be obtained even when the adjacent band-shaped members 110, 110 are bonded by the bonding material 120 to form a spiral tube.

  Specifically, the band-shaped member 110 has a plurality of T-shaped reinforcing ribs 112 standing on the back surface of the band-plate-like substrate 111 and also serves as a bonding portion on each of the left and right side edges of the substrate 111. A joint recess 113 is formed upright on the back side. On the other hand, the bonding material 120 has left and right bonding convex portions 121 as bonding portions that can be bonded to the one-side edge-side bonding recess 113 and the other-side edge-side bonding recess 113 in the adjacent strip-shaped members 110, 110, and adjacent to each other. It forms so that it may fit over the joining recessed parts 113 and 113 of the strip | belt-shaped members 110 and 110 to do.

  In order to obtain such a band-shaped member bundle 1 of the band-shaped member 110, the band-shaped member 110 is spirally wound around the drum 51 of the winding device 5 described above, and wound over the entire width of the set winding length drum 51. The hollow cylindrical belt-like member main body 11A is formed by overlapping.

  At this time, the width and height of the belt-shaped member 110 so that when the set winding length is wound, the belt-shaped member 110 of the final layer of the hollow cylindrical belt-shaped member body 11A is aligned over the entire width of the drum 51, The band-shaped member 110 is wound up based on the winding length, the width and inner diameter of the band-shaped member bundle 1, and the winding pitch of the band-shaped member 110.

  When the hollow cylindrical belt-like member main body 11A is thus formed, the outermost belt-like member 110 is further wound around the outer peripheral surface thereof. That is, as shown in FIG. 8, the bonding protrusion on the side corresponding to the bonding material 120 on the one-side edge-side bonding recess 113 on the side where the preceding band-shaped member 110 is bonded to the bonding portion recess 113 of the subsequent band-shaped member 110. 121 is inserted and the belt-shaped member 110 is wound up. Further, the pressing roller 6 is advanced with respect to the winding device 5 to press the preceding belt-like member 110 and the succeeding belt-like member 110 adjacent to each other (see FIG. 8).

  At this time, the drum 51 rotates and moves in the left-right direction, so that when the outermost belt-like member 110 is wound and made one turn, the joining convex portion of the joining material 120 joined to the preceding belt-like member 110. The other edge side joining recess 113 of the succeeding belt-like member 110 is opposed to 121 so as to be fitted from the outer peripheral side. Then, the subsequent belt-like member 110 is pressed in contact with the pressing roller 6 and joined to the joining convex portion 121 of the joining material 120 joined to the preceding belt-like member 110. That is, as shown in FIG. 9, the top portion of the joining recess 113 of the subsequent belt-like member 110 is pressed by the fitting roller 63 and is fitted into the joining convex portion 121 of the joining material 120 joined to the preceding belt-like member 110. The tubular body 11B is manufactured by the adjacent strip members 110, 110 joined via the joining material 120. Further, the guide roller 64 is disposed between the reinforcing ribs 112 and 112 of the adjacent belt-like members 110 and 110 and restricts the movement in the left-right direction.

  Hereinafter, similarly, the drum 51 rotates and moves in the left-right direction in synchronization with the rotation, so that the joining concave portion 113 of the belt-like member 110 that follows the entire width of the drum 51 via the pressing roller 6 is changed to the preceding belt-like shape. The tubular body 11 </ b> B extending over the entire width of the drum 51 is made by fitting into the joint convex portion 121 of the joint material 120 joined to the joint concave portion 113 of the member 110.

  If the tubular body 11B extending over the entire width of the drum 51 is formed by the outermost band member 110 and the bonding material 120, the driving of the winding device 5 is stopped, and after the band member 110 is cut, the hollow cylindrical band member The band-shaped member bundle 1 is manufactured by bundling the hollow cylindrical band-shaped member 11 formed from the main body 11A and the tubular body 11B at intervals in the circumferential direction. Next, after the belt-shaped member bundle 1 is covered with the UV deterioration preventing sheet 4, the winding device 5 is detached, mounted on the pallet, and stored.

  In the above-described embodiment, the case where the band-shaped member bundle 1 is manufactured using the winding device 5 has been illustrated, but it can also be manufactured using a manufacturing drum having a detachable winding core. .
