Description

  The present invention relates to a construction tool for a band-like member bundle wound in a hollow cylindrical shape for transporting a long belt-like member wound spirally to form a spiral tube, and a belt-like member for the construction jig. The present invention relates to a method for housing a bundle.

  In an existing pipe that has deteriorated, a belt-shaped member is wound in a spiral shape to form a spiral pipe, and the inner peripheral surface is lined with the spiral pipe that has been manufactured. In such an existing pipe lining method, since the belt-shaped member is fed into the existing pipe, it is necessary to transport the long belt-shaped member to the construction site.

  The belt-shaped member is usually transported to the site while being wound around a transport drum. The transport drum on which the belt-shaped member is wound is configured by connecting a cylindrical body between the center portions of a pair of disk-shaped side plates, and a long belt-shaped member is wound around the body to obtain a fixed length. When the belt-shaped member is wound, the body is pulled out from the side plate in a state where the belt-shaped member is wound. The transport drum on which the belt-like member is wound is transported to the construction site and temporarily placed, and the belt-like member is drawn out from the inner peripheral side of the transport drum and fed into the existing pipe, and spirally formed in the existing pipe. By being wound, spiral tubes are sequentially manufactured (see, for example, Patent Document 1).

  The length of the belt-shaped member wound around the transport drum is generally about 500 m to 2000 m, and the length of the spiral tube formed of this length of the belt-shaped member is about 2 m in diameter of the spiral tube. If it is about, it will be about 5-12 m. Therefore, when the lining length of the existing pipes is long, it is necessary to bring a large number of transport drums to the construction site.

  The transport drum is formed in a maximum length that can be transported by a truck or the like with a long strip-shaped member that can be transported at one time. Specifically, a transport drum having a side plate outer diameter of 3000 mm and a body length of about 1200 mm is often used. Therefore, if a large number of transport drums of this size are brought to the construction site and temporarily placed, traffic around the construction site may be congested or the pedestrian's passage may be blocked during the temporary placement period. is there.

  In order to avoid this problem, if the transport drums are brought into the construction site one by one, a large space is required in another place as a place for temporarily storing the transport drums. In addition, in a factory where a belt-shaped member is manufactured and wound around a transport drum, it is necessary to store a large number of transport drums until it becomes necessary. If there is more consumption than the manufacturable length, there is a possibility that a shortage of the supply amount of the belt-shaped member may sometimes occur.

  In response to such a problem, the applicant is able to stably store and transport the hollow cylindrical belt-like member while reliably preventing the unrolling of the hollow cylindrical belt-like member without using a transport drum. And a construction jig capable of safely pulling out the belt-like member from the inner peripheral side of the belt-like member bundle and supplying it to the existing pipe is proposed (for example, see Patent Document 2).

Japanese Patent No. 30223353 JP 2009-107723 A

  By the way, the construction jig described in the cited document 2 has a left and right side frame formed by connecting a plurality of reinforcing bars radially at intervals in the circumferential direction between the outer ring and the inner ring. A plurality of tension rods are detachably connected at intervals in the circumferential direction. Then, the band-shaped member bundle is accommodated between the left and right side frames with the hollow cylindrical portion facing in the left-right direction, and a plurality of tension rods are spaced apart in the circumferential direction across the left and right side frames. I try to connect them.

  Therefore, in order to accommodate and support the band-shaped member bundle with respect to the construction jig, after connecting a plurality of tension rods to the left and right side frames over a half circumference, the band-shaped member bundle is lifted to the left and right sides. A plurality of tension rods need to be fixed to the left and right side frames over the remaining half circumference in accordance with the outer periphery of the band-like member bundle accommodated in the left and right side frames.

  However, the work of lifting the band-shaped member bundle, positioning it on the left and right side frames and dropping it has the disadvantages that it requires skill and the work becomes complicated. In particular, in order to manufacture a rehabilitated pipe over a construction section, a large number of strip-shaped member bundles are required, so the time required to accommodate and hold one strip-shaped member bundle for a construction jig. However, the ratio of the time required for the housing work to the work time per day increases, and the pipe making work time is relatively reduced, so that the pipe making work for the set construction section cannot be achieved.

  The present invention has been made in view of such problems, and releases the binding of the band-shaped member bundle accommodated at the construction site, and safely pulls out the band-shaped member from the inner peripheral side of the hollow cylindrical band-shaped member. In addition to providing a construction jig that can be supplied to the construction jig, a housing method that can easily accommodate the band-shaped member bundle in the construction jig and reduce the time required for the housing operation is provided.

  The construction tool for the band-shaped member bundle of the present invention is bound by a plurality of binding materials in which the left and right side surfaces, the inner peripheral surface and the outer peripheral surface of the hollow cylindrical band-shaped member are wound at intervals in the circumferential direction.

The support connected across the connecting material at both ends of the material It is characterized in that for supporting the outer peripheral surface of the belt-shaped member bundles by the wood.

  According to the present invention, the left and right rotating bodies support the left and right side surfaces of the band-shaped member bundle, and the plurality of connecting members are connected within a range that does not exceed a half circumference with a spacing in the circumferential direction between the left and right rotating bodies. Since the outer peripheral surface of the band-shaped member bundle can be supported by the support member that is connected across the connecting members at both ends of these connecting materials, the inside of the hollow cylindrical band-shaped member that has been released from binding by the binding material The belt-like member can be pulled out from the peripheral side through the opening of one of the rotating bodies.

  As a result, the belt-like member can be safely pulled out and guided to the existing pipe while preventing the belt-like member from jumping up.

  Here, the diameter of the opening of the rotating body is preferably smaller than the inner diameter of the band-shaped member bundle. Accordingly, the belt-shaped member can be pulled out while being narrowed down by the opening of the rotating body, and the belt-shaped member can be reliably prevented from jumping out to the outside opposite to the pulling direction. In this case, if the diameter of the opening of the rotator is too small, the workability deteriorates, so about 70 to 80% of the diameter of the hollow cylindrical portion of the band-shaped member bundle is preferable.

  The method for housing the band-shaped member bundle in the construction jig of the present invention is a housing method for housing the band-shaped member bundle in the construction jig according to claim 1, and does not exceed a half circumference between the left and right rotating bodies. Rotate the construction jig or band-shaped member bundle that connects multiple connecting materials within the range, or rotate the construction jig and band-shaped member bundle to accommodate the band-shaped member bundle in the construction jig And supporting the remaining outer peripheral surface of the band-shaped member bundle by connecting the support members across the connecting members at both ends of the plurality of connecting members connected between the left and right rotating bodies. It is characterized by this.

The body is rotated to accommodate the band-shaped member bundle in the construction jig and supported by a plurality of connecting members. Subsequently, a support material is connected over the connection material of the both ends among the some connection materials connected between the right-and-left rotary bodies, and the remaining outer peripheral surface of a strip | belt-shaped member binding body is supported.

  As a result, the belt-shaped member bundle can be easily accommodated and supported by the construction jig by rotating the construction jig and / or the belt-shaped member bundle, so that the belt-shaped member bundle can be supported by a crane or the like. This eliminates the need for lifting and positioning, thereby reducing the time required for the housing operation.

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

  FIG. 1 shows an embodiment of a construction jig 1 for a band-shaped member bundle 10 of the present invention.

  First, prior to describing the construction jig 1, the band-shaped member bundle 10 will be described.

  This band-shaped member bundle 10 is formed into a hollow cylindrical shape by winding a band-shaped member 100 for producing a spiral tube for lining an aged existing pipe. As shown in FIG. 14, a hollow cylindrical band-shaped member 10A is formed. A plurality of cushioning materials 11 such as corrugated cardboard are circumferentially spaced over the outer circumferential surface, the inner circumferential surface, and the left and right side surfaces (see FIG. 6) (in the embodiment, four locations at 90 ° intervals). In addition, a binding material 12 such as a string or a band is wound around and bound to each buffer material 11.

  Thereby, since the strip | belt-shaped member binding body 10 is bundled by the binding material 12 in the direction which cross | intersects with respect to the winding direction of the hollow cylindrical strip | belt-shaped member 10A around which the strip | belt-shaped member 100 was wound, the strip | belt-shaped member 100 unraveling can be reliably prevented.

  Such a strip-shaped member bundle 10 is manufactured using a manufacturing drum or a winding device, although not shown in detail.

  When the band-like member bundle 10 is bound by the bundling material 12, the cardboard as a protective material is wound around the outer peripheral surface of the band-like member bundle 10, and then the cardboard is prevented from being damaged by rainwater or the like. Therefore, a film is laminated, and a light shielding sheet is placed on the outer peripheral surface and the left and right side surfaces of the band-shaped member bundle 10 to prevent the band-shaped member 100 from being deteriorated due to ultraviolet rays.

  Next, an embodiment of the construction jig 1 for transporting such a band-shaped member bundle 10 to the construction site, pulling out the band-shaped member 100 from the band-shaped member bundle 10 and supplying it to the existing pipe will be described.

  As shown in FIG. 1, the construction jig 1 includes a pair of left and right rotating bodies 2, 2 and a plurality of connecting members 3 detachably connectable between the rotating bodies 2, 2, for example, tension rods And a support member 4, which can be detachably connected to the connecting member 3, for example, a sheet.

  Each rotating body 2 includes an inner peripheral ring 21 and an outer peripheral ring 22 as openings 2a and a plurality of reinforcing bars 23 (radially connected between the inner peripheral ring 21 and the outer peripheral ring 22 in a circumferential interval. The reinforcing bar 23 is formed with a mounting hole 23a adjacent to the outer ring 22.

  The connecting member 3 is a rod-like body having the same structure with nuts (not shown) fixed at both ends, and the bolt 5 is screwed into the nut of the connecting member 3 through the mounting hole 23a of the reinforcing bar 23 in the rotating body 2. The connecting member 3 can be detachably connected to the rotating body 2.

  At this time, the attachment hole 23 a of the connecting member 3 is formed at a radial position corresponding to the outer diameter of the band-shaped member bundle 10. That is, when the belt-shaped member 100 having a required length is wound based on the width and height of the belt-shaped member 100 in advance, it is set by winding the belt-shaped member 100 at a pitch set with respect to a winding core having a set outer diameter. The outer cylindrical hollow cylindrical band member 10A (band member bundle 10) is manufactured, and the mounting hole 23a of the reinforcing bar 23 in the rotating body 2 is formed by the band member bundle 10 thus manufactured. It is formed at a position corresponding to the outer diameter.

  The support member 4 is provided with hook-shaped locking devices (not shown) that can be engaged with and disengaged from the connection material 3 at both ends, and the locking device on one end side has a length via a turnbuckle. Is provided to be adjustable.

  The construction jig 1 configured as described above includes a plurality of bolts 5 inserted through the mounting holes 23 a of the corresponding reinforcing bars 23 in the left and right rotating bodies 2, 2 and arranged between the left and right rotating bodies 2, 2.

It is assembled by locking the support material 4 via the locking tool over the connecting materials 3 and 3 at both ends (see FIG. 1).

  That is, when the strip-shaped member bundle 10 is accommodated in the construction jig 1, a plurality of pieces (5 in a drawing) are provided within a range that does not exceed a half circumference with a spacing in the circumferential direction between the left and right rotating bodies 2 and 2. The connecting jig 3 is connected in order, and the construction jig 1 is assembled in which the left and right rotating bodies 2, 2 are connected by a plurality of connecting members 3 at intervals in the circumferential direction (see FIG. 2).

  In this case, if the left and right rotating bodies 2 and 2 are self-supporting and the strength to support the band-shaped member bundle 10 is ensured, the plurality of connecting members 3 are not necessarily connected to the left and right rotating bodies 2 and 2 over a half circumference. It is not necessary, and a plurality of connecting members 3 may be connected at intervals in the circumferential direction over a range less than a half circumference.

  Next, the band-shaped member bundle 10 transported to the construction site and unloaded on the ground with the hollow cylindrical portion oriented horizontally (the band-shaped member bundle 10 has the light-shielding sheet, film and cardboard removed prior to transportation. ), The assembled construction jig 1 is brought close to the band-shaped member bundle 10 and the left and right rotating bodies 2, 2 are opposed so as to be substantially continuous with the left and right side surfaces of the band-shaped member bundle 10. (See FIG. 3), the construction jig 1 is rotated to cover the band-shaped member bundle 10 through the half-circumferential portion where the connecting material 3 is not connected. Next, the construction jig 1 is rotated together with the belt-like bundle 10, and the construction jig 1 is held in a state where the belt-like member bundle 10 is accommodated and supported across the plurality of connecting members 3 (see FIG. 4). . Then, after one end of the support member 4 is connected to one of the connection members 3 separated by a half of the plurality of connection members 3 connected to the rotating bodies 2 and 2 via a locking member, the band-shaped member bundle 10 The other end of the supporting member 4 is connected to the other connecting member 3 of the connecting members 3 at both ends via a locking tool and a turnbuckle, and is not supported by the plurality of connecting members 3. The remaining half of the outer peripheral surface of the band-shaped member bundle 10 is supported by the support material 4. As a result, the band-shaped member bundle 10 is accommodated in the construction jig 1 with the axial center substantially coincided, and the outer peripheral surface thereof is supported by the plurality of connecting members 3 and the supporting members 4, and the left and right side surfaces thereof are further supported. It can be supported by the left and right rotating bodies 2 and 2 (see FIG. 5).

  Next, the left and right rotating bodies 2 and 2 of the construction jig 1 that accommodates and supports the band-shaped member bundle 10 are placed on a turntable 20 that is formed by pivotally supporting a pair of rotating rollers 21, and The binding material 12 is cut | disconnected and fixation of the direction which cross | intersects the winding direction of the strip | belt-shaped member 100 is cancelled | released (refer FIG. 6). Thereby, the construction jig 1 accommodating the hollow cylindrical belt-like member 10A can be rotatably supported.

  Thereafter, the winding start end portion of the band-shaped member 100 is pulled out from the inner peripheral side of the hollow cylindrical band-shaped member 10 </ b> A, and is pulled out through the inner peripheral ring 21 of one rotating body 2. Thereby, the one end part of the strip | belt-shaped member 100 can be guide | induced into the existing pipe | tube through the manhole which is not shown in figure.

  At this time, the belt-like member 100 drawn out from the inner peripheral side of the hollow cylindrical belt-like member 10 </ b> A is regulated and drawn out by the inner peripheral ring 21 of the rotating body 2. That is, the outer diameter of the inner peripheral ring 21 of the rotating body 2 is set to be smaller than the inner diameter of the hollow cylindrical portion of the band-shaped member bundle 10, and the hollow member 100 is pulled out from the inner peripheral side. The inner diameter of the portion gradually increases, but is always drawn out by passing through the inner ring 21 having a smaller diameter than the inner diameter of the hollow cylindrical portion. Therefore, the belt-like member 100 does not jump up and down in the hollow cylindrical portion or jumps out to the opposite side to the pulling direction, and the belt-like member 100 can be safely pulled out in a stable posture and without being caught. it can.

  In the above-described embodiment, the case where the tension rod is used as the connecting member 3 has been described. However, the embodiment is not limited to the tension rod. For example, connecting rods may be provided at both ends of a plate material bent in an arc shape or a polygon shape to form a connecting material 3A, and the connecting material 3A may be connected to the left and right rotating bodies 2 and 2 at intervals in the circumferential direction. (See FIG. 7). Further, when a tension rod is used as the connecting member 3, the cross-sectional shape is not limited to a circle, and any shape can be adopted.

  Further, the rotating body 2 includes a case in which the inner peripheral ring 21, the outer peripheral ring 22, and a plurality of reinforcing bars 23 that are radially connected between the inner peripheral ring 21 and the outer peripheral ring 22 in the circumferential direction. Although described, it is not limited to such a structure. For example, as shown in FIG. 8, a disk-shaped rotating body 2A may be used. In this case, at least one disk-like rotator 2 is formed with an opening 2a for drawing the belt-like member 100 from the inner peripheral side of the hollow cylindrical belt-like member 10A at the center thereof.

  Furthermore, although the sheet | seat was illustrated as the support material 4, what is necessary is just to be able to support the remaining outer peripheral surface of the strip | belt-shaped member binding body 10 supported with the connection material 3 continuously in the circumferential direction, and a net | network and a net | network can also be used. A pair of chains may be connected in a ladder shape to form the support member 4.
