It is related with the rope for suspension for moving.

  Stones are laid on riverbeds and grounds in rivers and coastal roots and revetments. At this time, if stones are laid one by one, they are swept away by water flow or waves, and therefore, a plurality of stones are connected and laid.

  Conventionally, metal anchors have been used as stone connecting tools. However, since they are made of metal, they are rusted and brittle, and cannot be used for a long time. For this reason, it has been proposed to use a synthetic fiber rope as a connector (Patent Document 1).

  This synthetic fiber rope is composed of a twisted rope in which three strands containing a core-sheath type heat-sealing filament containing a sheath component as a heat-sealing component are twisted together and twisted. It has been made highly rigid by fusing and solidifying with a sheath component of the mold heat-sealing filament (paragraph 0037 of Patent Document 1).

  This synthetic fiber rope is used as a connector as follows. That is, after drilling holes in two stones, inserting one end part of the synthetic fiber rope into one stone hole, and inserting the other end part of the synthetic fiber rope into the other stone hole, Each hole is filled with a curable resin to complete the curing, and the two stones are connected with a synthetic fiber rope.

JP 2010-43447 A (Claims and paragraph 0037)

  The synthetic fiber rope described in Patent Document 1 is not easily rusted and can be used over a long period of time. However, since the end portion of the synthetic fiber rope is relatively smooth just by twisting the strands together, it can be easily pulled out even if inserted into a stone hole and hardened with a curable resin. was there. Accordingly, the present invention provides a bulb-like bulge at the end portion inserted into the hole in the stone to increase the anchoring effect on the hardened curable resin, making it difficult for the synthetic fiber rope to be pulled out from the hole. It is.

  That is, the present invention comprises a twisted rope obtained by twisting at least three strands containing a core-sheath-type heat-sealing filament containing a sheath component as a heat-sealing component, In the connecting rope that has been made highly rigid by fusing and solidifying with the sheath component of the fused filament, the connecting rope has anchor portions at both end portions, and the anchor portion has a predetermined length at the end of the twisted rope.

That is, it has a connecting rope anchor at one end of the rope and a ring at the other end, and the ring is untwisted at a predetermined length at the other end of the twisted rope. And the untwisted part separated into three strand bundles a, b and c from the untwisting start point, and a ring is formed in the untwisted part, and the ring is not formed. The present invention relates to a hanging rope in which the ends of each of the strand bundles a, b and c are inserted between the strands of the part.

  The present invention also relates to a method for connecting two stones using the connecting rope described above, wherein one anchor is inserted into a hole drilled in the stone and the other anchor is drilled in another stone. The present invention relates to a method for connecting stones using a connecting rope, wherein the hole is filled with a curable adhesive and then cured.

  The present invention also relates to a method for attaching the above-described hanging rope to a stone material, wherein the anchor portion is inserted into a hole drilled in the stone material, and then the curable adhesive is filled into the hole and cured. It is related with the attachment method to the stone material of the rope for hanging. The stone material to which the hanging rope is attached can be moved by a crane or the like by hooking the ring portion of the hanging rope with a hook or the like.

In addition, the present invention relates to a stone with a connecting rope, wherein one anchor portion of the connecting rope is fixed in a state of being embedded in the stone. Such a stone with a connecting rope is obtained by making a hole in a stone, inserting an anchor portion of the connecting rope into this hole, and then filling the hole with a curable adhesive and curing it. Further, when the stone material is a pseudo-stone or concrete block, after the pseudo-stone raw material or concrete raw material is filled in the mold, one anchor portion of the connecting rope is inserted into the pseudo-stone raw material or the concrete raw material, It can also be obtained by solidifying the pseudo-stone raw material or the concrete raw material. The pseudo-stone with a connecting rope or the concrete block obtained by the latter method does not use a curable resin.

The present invention also relates to a stone material with a hanging rope, wherein the anchor portion of the hanging rope is fixed in a state of being embedded in the stone material. Such a stone with a rope to be suspended is obtained by making a hole in the stone, inserting an anchor portion of the rope for suspension into this hole, and then filling the hole with a curable adhesive and curing it.

FIG. 4 schematically shows another method for forming an anchor portion of a connecting rope or a hanging rope according to another example of the present invention. FIG. 5 schematically shows one method for forming the ring portion of the hanging rope of the present invention.

  The connecting rope or the hanging rope according to the present invention is a twisted rope. A twisted rope is one in which at least three strands are aligned and twisted. In the present invention, a three-stranded rope is generally used. In the present invention, a core-sheath type heat-sealing filament having a sheath component as a heat-sealing component is contained in the strand. In general, a strand is composed of a plurality of filaments, and each of the plurality of filaments may be a core-sheath type heat-sealed filament, or a single-phase filament is mixed with the core-sheath type heat-welded filament. It may be. As the core-sheath type heat-sealing filament, for example, a filament in which the sheath component is a low-melting polyester and the core component is a high-melting polyester is employed. When heat is applied to the filament, the core component does not melt or soften, but the sheath component melts or softens, and the filaments in the strands or between the strands are heat-sealed. And since a sheath component solidifies after this heat fusion, as for a twisted rope, a filament and a strand become difficult to move, and it becomes highly rigid. The heat is applied after the anchor portion 1 and the ring portion 2 described later are formed.

  The connecting rope according to the present invention has anchor portions 1 and 1 at both ends of the twisted rope. Moreover, it has the anchor part 1 in the one terminal site | part of the hanging rope which concerns on this invention. Each anchor portion 1 is created by untwisting a predetermined length at the end of a twisted rope. A specific example of the creation procedure is as shown in FIG. That is, a predetermined length at the end of the twisted rope is untwisted to form an untwisted portion separated into three strand bundles A, B, and C ((1) in FIG. 3). When the twisted rope is a three-stranded rope, each of the strand bundles A, B, and C is composed of one strand. When the twisted rope is a four-stranded rope, the strand bundle A may be composed of two strands, and the strand bundles B and C may be composed of one strand. The untwisting may be performed from the untwisting start point 3, and the lengths of the untwisted strand bundles A, B, and C may be about 2 to 6 cm, respectively. In addition, the part which is not untwisted becomes the untwisted part 4, and maintains the form of the original twisted rope as it is. Moreover, it is preferable to bind the periphery of the untwisting start point 3 with a yarn or the like so that the untwisted portion 4 is not untwisted during untwisting.

  Next, the strand bundle A is formed into a loop shape on the back side of the strand bundle B ((2) in FIG. 3). Then, the end of the strand bundle B is positioned on the front side of the strand bundle C while turning the strand bundle B to the back side of the loop-like strand bundle A to form a loop shape ((3) in FIG. 3). Next, while making the strand bundle C into a loop shape, the end of the strand bundle C is passed through the loop formed by the strand bundle A ((4) in FIG. 3). Then, the ends of the strand bundles A, B, and C are tightened in the direction of the untwisted portion 4 ((5) in FIG. 3). In the above procedure, the strand bundle A is a loop formed by the strand bundle B, the strand bundle B is a loop formed by the strand bundle C, and the strand bundle C is a loop formed by the strand bundle A. It is fastened to the untwisting start point 3 to form a dumpling. Thereafter, the ends of the strand bundles A, B and C are sequentially inserted between the twisted strands of the untwisted portion 4. As described above, the anchor portion 1 can be obtained.

  Moreover, the anchor part 1 can be obtained also by the procedure shown in FIG. First, as in the case of FIG. 3, the twisted rope is untwisted to form strand bundles A, B, and C ((1) in FIG. 4). The strand bundle A is turned from the front side to the back side of the strand bundle C to make a loop shape, and the vicinity of the untwisting start point 3 of the strand bundle C is loosened to make a loop shape ((2) in FIG. 4). Next, a loop is formed with the strand bundle B, and the end of the strand bundle A is passed through this loop ((3) in FIG. 4). Thereafter, the end of the strand bundle B is passed through the loop of the strand bundle C ((4) in FIG. 4). In the above procedure, the strand bundle A is a loop formed by the strand bundle B, the strand bundle B is a loop formed by the strand bundle C, and the strand bundle C is a loop formed by the strand bundle A. It is fastened to the untwisting start point 3 to form a dumpling. Thereafter, the ends of the strand bundles A, B and C are sequentially inserted between the twisted strands of the untwisted portion 4. As described above, the anchor portion 1 can be obtained.

Moreover, the hanging rope according to the present invention has a ring portion 2 at the other end portion. The ring portion 2 can be created by a procedure as shown in FIG. First, as in the case of the anchor part 1, a predetermined length at the end of the twisted rope is untwisted to form an untwisted part separated into three strand bundles a, b and c, and an untwisted part 4 Is bent into a loop ((1) in FIG. 5). Then, the strand bundles a, b and c are sequentially inserted between the strands of the untwisted portion 4 in a state where the untwisted start point 3 is brought into contact with the untwisted portion 4 to form a closed loop ((2 in FIG. 5). )). Thereby, the ring part 2 can be obtained.
The connecting rope and the hanging rope that created the anchor part 1 and the ring part 2 are then heated to the core-sheath type heat-sealing filament to melt or soften the sheath component, and then cooled to solidify. However, increasing the rigidity is as described above.

  The connecting rope according to the present invention can be used as follows. First, make a hole in the stone. Although the shape of the hole is arbitrary, it is generally cylindrical and has an inner diameter of 2 to 5 cm and a depth of about 5 to 15 cm. In the case of a connecting rope, one anchor portion 1 is inserted into a stone hole, and the other anchor portion 1 is inserted into another stone hole. And if the hole of each stone is filled with a curable adhesive and cured, the two stones can be connected. A conventionally well-known thing is used as curable resin. For example, a two-component room temperature curable resin composed of a curing agent and a resin is preferably used. Further, a one-component type moisture curable resin that is cured by moisture in the atmosphere is also used. As the resin, a modified acrylic resin, an epoxy resin, or the like is used.

  In the case of the hanging rope according to the present invention, similarly to the connecting rope, the anchor portion 1 may be inserted into a hole in the stone, and the hole may be filled with a curable resin and cured. If the hanging rope is attached to the stone, the ring portion 2 can be hooked on a hook such as a crane, and the stone can be freely conveyed to any place.

  In the case of a hanging rope, two or more of these can be combined to form a connecting rope. That is, if the ring portions 2 of two hanging ropes are connected to each other, a connecting rope having anchor portions 1 and 1 at both ends is obtained. Moreover, if the ring parts 2 and 2 of two hanging ropes are connected to one ring, it will become a connecting rope which has the anchor parts 1 and 1 at both ends. Such ring portions 2 or the ring portions 2 and the ring may be connected not only to two but also to three or more. When three or more are connected, a connecting rope having three or more anchor portions 1, 1, 1... Can be obtained. In addition, connecting the ring parts 2 or connecting the ring part 2 and the ring is made while creating the ring part 2, and after connecting, heat is applied to the sheath component of the core-sheath type heat fusion filament, Increases rigidity.

  Furthermore, in the present invention, a connecting rope or a hanging rope may be fixed to the stone in advance. Specifically, after drilling a hole in a stone and inserting the anchor portion 1 of the connecting rope or the hanging rope into this hole, the anchor portion 1 becomes the stone by filling the hole with a curable resin and curing it. It is possible to obtain a stone with a connecting rope or a hanging rope that is embedded and fixed. Further, when the stone is a pseudo stone or a concrete block, the stone with the connecting rope or the hanging rope can be obtained by the following method. First, a pseudo-stone raw material made of stone grains, an adhesive or the like, or a concrete raw material made of gravel, cement or the like is prepared. And after filling a formwork with a pseudo-stone raw material or a concrete raw material, the anchor part 1 of a connecting rope or a hanging rope is inserted in this pseudo-stone raw material or concrete raw material. Thereafter, if the pseudo-stone raw material or the concrete raw material is solidified, a connecting rope or a hanging rope is obtained in which the anchor portion 1 of the connecting rope or the hanging rope is fixed in a state of being embedded in the pseudo-stone or the concrete. be able to.
