Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a packaging member for protecting a hollow cylindrical annular body formed by concentrically winding long strip-shaped members and a storage device for the annular body.

Conventionally, when existing pipes such as sewer pipes and agricultural water pipes are aged, form a tubular body (rehabilitation pipe) along the inner peripheral surface of the existing pipe while sequentially supplying long strip-shaped members into the existing pipe. Therefore, it is widely practiced to rehabilitate the inner surface of the existing pipe.

Such a long strip-shaped member forming a rehabilitation pipe is usually stored in a factory or the like in a state of being wound around a transport drum in consideration of convenience during construction. In this way, if the long strip-shaped member is stored in a state that it is wound around the transportation drum, it can be transported to the construction site as it is, set this transportation drum on the turntable, and then transported. By directly feeding the strip-shaped member from the drum for use, it becomes possible to easily feed the strip-shaped member into the existing pipe.

By the way, since there is a limited storage space in factories and the like, recently, a so-called drumless storage mode in which a transport drum is not used has been proposed instead of a storage mode in which a transport drum, which tends to be bulky, is used. .. Further, a packaging member for an annular body has been proposed so that the belt-shaped member will not be contaminated during storage/transportation.

For example, in Patent Document 1, a main covering member that is deformed into a shape that covers the outer peripheral surface and both end surfaces of the annular body by being stretched with pleats, and the main covering member that is folded toward the center hole of the annular body There has been proposed a packaging material for an annular body, which includes an inner circumferential covering member that covers a circumferential surface.

As shown in FIGS. 1 to 3, the storage device 1 for a ring-shaped body is for storing the hollow cylindrical ring-shaped body 10 placed on a pallet (loading platform) 12. The ring-shaped storage device 1 includes four binding members 2 and 5 that bundle the band-shaped members 11 that form the ring-shaped body 10 vertically and horizontally, and a pair of stoppers 8 and 8 that support the vicinity of the lower end of the ring-shaped body 10. 2), a wrapping member 9 that covers the entire annular body 10 (see FIG. 2), and a lashing belt (fixing tool) 13 that fixes the annular body 10 to the pallet 12.

-Ring body-
As shown in FIG. 1, when the existing pipe such as a sewer pipe or an agricultural water pipe is deteriorated, the annular body 10 to be stored in the present embodiment is spirally wound into a tubular body ( By forming a rehabilitation pipe), it is configured by a long strip-shaped member (long member) 11 that rehearses the inner peripheral surface of the existing pipe. Specifically, the annular body 10 is formed in a hollow cylindrical shape as shown in FIG. 1 by concentrically winding the strip-shaped members 11 using a manufacturing drum (not shown). Then, the annular body 10 has four binding members 2 and 5 constituting the annular body storage tool 1 so that the belt-shaped member 11 is maintained in a concentrically wound state even after the manufacturing drum is removed. The upper end portion, the lower end portion, and the left and right side end portions are bound together. The annular body 10 has a diameter of 2000 mm and a depth of 1200 mm, for example.

The annular body 10 formed in a hollow cylindrical shape is hoisted and conveyed by a crane or the like via a hoisting jig 26 (see FIG. 8A) passing through the hollow portion 10a. Therefore, if the annular body 10 is stored such that the cylinder axis (the axial direction of the annular body 10) P is in the vertical direction, it takes time and effort to raise the annular body 10 each time it is transported or constructed. Therefore, as shown in FIG. 3, the annular body 10 is placed on the pallet 12 so that the cylinder axis P is in the horizontal direction. When the annular body 10 is placed on the pallet 12, an opening 12a is formed in a direction substantially parallel to the cylinder axis P of the annular body 10. The openings 12a are formed at two places with a space therebetween. The annular body 10 placed on the pallet 12 is fixed to the pallet 12 by passing the lashing belt 13 passing through the opening 12a through the hollow portion 10a of the annular body 10 and winding the lashing belt 13 around the lower end of the annular body 10.

Is provided with a pair of stoppers 8, 8 arranged on the upper surface, a packaging member 9 that covers the annular body 10, and a lashing belt 13 that fixes the annular body 10 to the pallet 12.

FIG. 4 is a development view schematically showing the cushioning material 3 of the binding material 2 and the cushioning material 6 of the binding material 5. FIG. 4A shows the upper end portion and the left and right side end portions of the annular body 10. The cushioning material 3 to be wound is shown, and FIG. 3B shows the cushioning material 6 to be wound around the lower end of the annular body 10. In the following, the binding material wound around the lower end of the annular body 10 is particularly referred to as the lower binding material 5, and the other binding materials are simply referred to as the binding material 2.

The binding material 2 bundles the band-shaped members 11 in a direction intersecting the circumferential direction of the annular body 10. The binding material 2 is wound between the annular body 10 and the binding band 4, which is wound in a direction crossing the circumferential direction of the annular body 10 to tighten the annular body 10, and the annular body 10 is damaged. And a cushioning material 3 for preventing the above. The cushioning material 3 is a belt-shaped member formed of a resin material such as polyethylene. As shown in FIG. 4A, the cushioning material 3 is formed with four folds 3a, and is configured to be easily bent at these folds 3a. Further, the cushioning material 3 is configured such that the central portion 3b covers the outer peripheral surface 10c of the annular body 10. Further, the first bent portion 3c, which is bent at a substantially right angle to the central portion 3b through the fold 3a, covers the end faces 10d arranged at both ends of the annular body 10 in the cylinder axis P direction. Further, a second bent portion 3d, which is bent at a substantially right angle to the first bent portion 3c via the fold 3a so as to face the central portion 3b, is configured to cover the inner peripheral surface 10e of the annular body 10. ..

Like the binding material 2, the lower binding material 5 is also composed of a binding band 7 and a cushioning material 6. Like the cushioning material 3, the cushioning material 6 is a strip-shaped member made of a resin material such as polyethylene, and has four folds 6a as shown in FIG. 4B. It is configured to be easily bent at 6a. The cushioning material 6 has a width wider than that of the cushioning material 3. More specifically, the lower bundling material 5 is provided in the annular body 10 so that the lashing belt 13 wound around the lower end of the annular body 10 through the hollow portion 10a does not come into direct contact with the annular body 10 (strip member 11). It has a width that covers the inner peripheral edge 10b and also covers the outer peripheral surface (lower end surface) 10c of the annular body 10 between the pair of stoppers 8, 8.

The cushioning member 6 is configured such that the central portion 6b covers the outer peripheral surface (lower end surface) 10c of the annular body 10. A first bent portion 6c, which is bent at a substantially right angle to the central portion 6b via the fold line 6a, covers the end surface 10d of the annular body 10. Further, a second bent portion 6d, which is bent at a substantially right angle to the first bent portion 6c via the fold line 6a so as to face the central portion 6b, is configured to cover the inner peripheral surface 10e of the annular body 10. There is.

The total length of the two second bent portions 3d, 3d (6d, 6d) is shorter than the length of the central portion 3b (6b). That is, there is a portion where the cushioning material 3 (6) is not interposed between the inner peripheral surface 10e of the annular body 10 and the binding band 4 (7). A gap is provided between the inner peripheral surface 10e of the annular body 10 and the binding band 4 (7) by the thickness of the cushioning material 3 (6). Therefore, even if the binding band 4 (7) is fastened to the annular body 10, the annular body 10 is not damaged by the binding band 4 (7). Similarly, even if the lashing belt 13 is tightened so as to overlap the cushioning material 6, the annular body 10 is not damaged by the lashing belt 13.

The pair of stoppers 8 and 8 are substantially wedge-shaped members formed of, for example, foam resin. The stopper 8 is formed with a projection 8a that projects downward from the lower surface (see FIG. 3). The pair of stoppers 8 and 8 are arranged on the pallet 12 with the projections 8a inserted into the upwardly opening recesses 12b formed in the pallet 12 so that the distance between the tips is smaller than the width of the cushioning material 6. It is configured to be supported and fixed to. When the annular body 10 is placed on the pair of stoppers 8 and 8 arranged on the pallet 12, the pair of stoppers 8 and 8 sandwich the outer peripheral surface (lower end surface) 10c of the annular body 10 in the circumferential direction and form the pallet. It is configured to support the annular body 10 in a state of being slightly floated from 12. Although the annular body 10 has a considerable weight, since the annular body 10 is supported by the stopper 8 made of foamed resin having a high cushioning property, the belt-shaped member 11 constituting the annular body 10 is damaged during storage. Can be suppressed.

-Packaging material-
As shown in FIGS. 2 and 5, the packaging member 9 is made of, for example, a resin material such as polyethylene, and has a bag shape with an open bottom.

More specifically, the packaging member 9 includes a pair of first face materials (first covering portions) 40 and 40 that covers both end surfaces 10d and 10d of the annular body 10 and the opening 10h of the hollow portion 10a, and the annular body 10. A second face material (second covering portion) 41 that covers both sides and an upper portion of the outer peripheral surface 10c (covers a portion of the outer peripheral surface 10c except a portion facing the pallet 12), a first surface member 40, and a second surface. An opening portion 46 formed by the lower end of the material 41 and detachably attached to the annular body 10 in the vertical direction is provided. The second face material 41 is provided with a pocket 42 for enclosing a label in which contents and a destination of transportation are described. Although not shown, the lower end of the packaging member 9 may be fixed to the pallet 12 with a string or the like so that the packaging member 9 does not roll up or come off due to wind or the like.

Here, each of the first face members 40, 40 of the packaging member 9 is configured such that a part of the face member can be opened and closed. Specifically, a notch is formed from the lower end portion 44 of the first surface member 40 toward the upper side passing near the cylinder axis P of the annular body 10, and a fastener (opening/closing portion) 43 is provided at the notched portion. .. That is, as shown in FIG. 6, by opening the fastener 43, the first face material 40 can be rolled up in both left and right directions with the cut portion as a boundary. That is, by opening the fastener 43 and rolling up the first surface member 40, the hollow portion 10a of the annular body 10 can be communicated with the outside. In this embodiment, a resin line fastener (zipper, chuck) is provided as the fastener 43. In addition to the fastener 43, the opening/closing portion may be formed of a metal line fastener, a surface fastener (velcro (registered trademark), Velcro (registered trademark)), a hook, or the like.
Further, holding members 47, 48 such as a magic tape or a button are provided so that the lower end portion 44 of the first face material 40 can be held by the second face material 41 when the first face material 40 is rolled up. It is preferable to keep it. In this embodiment, the convex member 47 of the snap button is attached to the first surface member 40, and the concave member 48 of the snap button is attached to the second surface member 41. Further, the recessed members 48 of the second surface member 41 are attached at two positions according to the size of the fastener 43 in the open state. The concave member 48 may be provided on the first face member 40 as long as it can hold the rolled-up state. Further, the holding members 47 and 48 may be configured by surface fasteners or the like.

When the fastener 43 of the first face material 40 of the packaging member 9 is opened and the first face material 40 is rolled up, the lower end portion 10g of the hollow portion 10a of the annular body 10 is visible (exposed).

Next, as shown by the white circles in FIG. 7B, the annular body 10 can be inserted upward into the space defined by the pair of frame bodies 21 and 21 and the eight rods 22, as shown by the white circles in FIG. 7B. The three positioned rods 22 are removed from the pair of frame bodies 21.

In this way, when the annular body 10 is ready to be housed in the construction jig 20, the annular body 10 has been conveyed in a state of being stored by the annular body storage tool 1 as shown in FIG. 7C. Is stored in the construction jig 20. Specifically, as shown in FIG. 7D, after the fastener 43 of the packaging member 9 is fully opened, the first surface member 40 is rolled up to the left and right to form the upper end portion 10f of the hollow portion 10a of the annular body 10. To be visible (exposed). At this time, the lower end portion 44 of the first face material 40 may be held on the second face material 41 by the holding members 47 and 48. After that, the lashing belt 13 is removed to release the fixation between the annular body 10 and the pallet 12 (and the truck bed). Even if the lashing belt 13 is removed in this manner, the annular body 10 is supported by the pair of stoppers 8 and 8, so that the annular body 10 does not roll off from the pallet 12.

Then, as shown in FIG. 8A, the hoisting jig 26 is passed through the hollow portion 10a of the annular body 10, and the holing jig 26 is used to hoist the annular body 10 from the pallet 12 through the hoisting jig 26. Move to the construction jig 20. At this time, the lifting jig 26 is attached to the hollow portion 10a of the annular body 10. However, even when the packaging member 9 is attached, the upper end portion 10f of the hollow portion 10a can be visually recognized, so that the lifting jig 26 can be easily attached. Can be installed.

Next, as shown in FIG. 8B, the annular body 10 is set in the space defined by the pair of frame bodies 21 and 21 and the five rods 22. After accommodating the annular body 10 in the construction jig 20, the packaging member 9 is removed from the annular body 10. Since the state in which the packaging member 9 is attached to the annular body 10 can be maintained up to this stage, it is possible to more reliably prevent the band-shaped member 11 forming the annular body 10 from being damaged. it can.

Next, as shown in FIG. 8C, the three rods 22 removed from the pair of frame bodies 21 and 21 are attached to the pair of frame bodies 21 and 21 again, and the construction jig 20 rotates. Also, the annular body 10 is prevented from rolling out of the construction jig 20.

When the setting of the annular body 10 on the construction jig 20 is completed, the four binding members 2 and 5 that bundle the band-shaped members 11 are removed from the annular body 10. Then, as shown in FIG. 8D, if the end portion of the belt-shaped member 11 located on the inner peripheral portion of the annular body 10 is pulled out from the inner side of the inner peripheral ring 23, it is set on the rotary table 30 for construction. Since the jig 20 rotates and the strip-shaped member 11 is sequentially fed out, it becomes possible to easily feed the strip-shaped member 11 into the existing pipe.

According to the present embodiment, when the annular body 10 is subjected to on-site construction, the annular body 10 is transferred to the construction jig 20 after the lashing belt 13 is unfixed at the site, and then the packaging member 9 is annularly arranged. The annular body 10 can be set on the construction jig 20 by a simple operation of removing it from the body 10. That is, it is possible to reduce the storage space as compared with the case where the transportation drum is used for storage, and to maintain the workability equivalent to that when the transportation drum is used. Further, since the packaging member 9 is formed in a bag shape and is attached so as to cover the annular body 10 from above, it can be easily attached. Furthermore, as described above, since the annular body 10 can be held with the packaging member 9 attached until it is transferred to the construction jig 20, the annular body 10 is prevented from being soiled or damaged by rainwater, dust, or the like. be able to.

Although one embodiment of the packaging member according to the present invention has been described above, the present invention is not limited to the above-described one embodiment and can be appropriately modified without departing from the gist thereof.

In the packaging member 9 of the above embodiment, the case where the notch is formed from the lower end portion 44 of the first surface member 40 toward the upper side passing near the cylinder axis P of the annular body 10 has been described. As shown in FIG. 10, the packaging member 90 may be provided with two fasteners 43, 43 on the left and right sides of the first surface member 40 in front view.

Moreover, although the said embodiment demonstrated using the annular body 10 which wound up the elongate strip|belt-shaped member 11 which forms a rehabilitation pipe, it is not restricted to this, For example, the heat collection pipe used for a sewage heat utilization system is wound. The present invention may be applied to a laminated annular body, an annular body in which various wire rods such as electric wires are rolled into a hollow cylinder, a pulp roll in which a pulp sheet or the like is rolled into a hollow cylinder.

Further, in the above-described embodiment, only the buffer material 6 of the lower binding material 5 of the four binding materials 2 and 5 is wider than the buffer material 3 of the other binding material 2, but not limited to this, for example, The cushioning material 3 of the binding material 2 wound around the upper end may be wide. With this configuration, it is possible to prevent the strip-shaped member 11 forming the annular body 10 from being damaged when the annular body 10 is lifted through the lifting jig 26.

Furthermore, in the above-described embodiment, the bag-shaped packaging member 9 having an opening at the lower side is covered on the annular body 10. However, in addition to this, the opening 46 of the packaging member 9 may be a purse-like shape. In this way, by covering the annular body 10 with the packaging member 9 and then squeezing the purse-like opening 46, it is possible to further suppress the annular body 10 from being contaminated by rainwater, dust, or the like.

And in the said embodiment, although it comprised so that it could be opened and closed from the lower end part 44 of the 1st surface material 40 in the packaging member 9 to the position where the upper end part 10f of the hollow part 10a can be visually recognized, as shown in FIG. 900 may be provided with an opening/closing portion 943 that can be partially opened/closed at a position facing the upper end 10f of the hollow portion 10a. That is, it is configured such that the fastener 43 can be opened and closed from the lower end portion 44 of the packaging member 900 to the position where the lower end portion 10g of the hollow portion 10a is visible, and the position facing the upper end portion 10f of the hollow portion 10a is like a small window. An opening/closing portion 943 that can be partially opened/closed may be provided. With this configuration, when the annular body 10 is transferred to the construction jig 20, only the opening/closing portion 943 for inserting the lifting jig 26 in the packaging member 900 may be opened. It is possible to transfer the substantially whole of 10 covered with the packaging member 900.
