Description

  The present invention relates to a crane suspension mainly for suspending a scaffold member in a construction site.

  When constructing a structure, various temporary materials such as frame scaffolds, single pipes, scaffolding plates and brackets are used to assemble temporary scaffolds for work, and these temporary scaffolds are used to reinforce construction, formwork, concrete placement. In addition to performing various processes such as installation work, support materials such as square pillars and pipe supports are used in formwork.

  After these temporary materials and supporting materials are carried to the site by truck, they are temporarily stored in a material storage site in the site by a tower crane, a truck crane, or the like.

  Here, in order to move temporary materials and support materials from a truck to a material storage site using a crane, it is indispensable to hang a wire using a wire, but temporary materials and support materials are long pipes, pipe supports, etc. In the case of a scale member, a plurality of long members are often bundled and hung by a method called so-called two-point two-point piercing-through fishing (a type of two fishing).

  The above-described two-hanging hang-up method needs to be tied together so that the suspended load does not slide down, and the slinging position by the wire rope is the position where the suspended load can be balanced, that is, the true center of gravity of the suspended load It must be hung by a crane above and kept stable while holding the suspended load horizontally.

  However, the slinging method as described above can only be relied on by inspection by an operator, but rather it is difficult to hold the suspended load accurately in the horizontal direction. It was a burden.

  Even when slinging is performed as described above, when the suspended load is moved by the truck crane, the suspended load becomes very unstable due to the wind or swinging of the truck crane, and the slinging position of the suspended load is There is a concern that it may deviate from the center of gravity and, as a result, cause the suspended load to slide down. For this reason, there was a problem that the construction had to be interrupted on windy days.

  The present invention has been made in consideration of the above-described circumstances, and provides a crane lifting tool capable of preventing the scaffolding member from sliding off when the scaffolding material is mainly suspended by the crane and moved. For the purpose.

  In order to achieve the above-mentioned object, a crane suspension according to the present invention is a pair of cranes, each of which accommodates each accommodating end from each end to a predetermined length of the long member. An end container and a pair of suspension members formed at one end with a hook part hooked to the hook of the crane and the other end attached to each end container, the end container is An opening into which the receiving end of the elongate member is inserted is formed, and a bottom is formed on which each end of the elongate member comes into contact with the end surface.

  In addition, the crane lifting tool according to the present invention is configured such that the suspension member is formed of a wire rope, a shackle or an eye is provided at the other end of the wire rope, and at least the vicinity of the opening of the end container. The ring accompanying the suspension of the crane by attaching a ring-shaped annular portion made of a flexible material and having one end of the wire rope inserted through the shackle or eye in the vicinity of the opening of the end container. The opening is configured to be retractable as the inner diameter of the annular portion decreases.

  In addition, the crane suspension according to the present invention includes the end portion container including the bottom portion and a cylindrical body connected to the bottom portion, and the bottom portion includes a plurality of shapes so that the overall shape is substantially circular. A bottom wire is knitted in a lattice shape, and each end of the plurality of bottom wires is knitted into a bottom peripheral wire, and the cylindrical body is formed by concentrically arranging a plurality of annular wires having different diameters and substantially orthogonal to them. A plurality of vertical wires are knitted into the annular wire vertically and horizontally, and among the annular wires, the bottom side annular wire is the one with the smallest diameter and located on the center side, and the bottom side annular wire and the bottom peripheral edge wire Is inserted into the ring member so that the cylindrical body can stand upright with respect to the bottom portion, and the diameter of the annular wire is the largest on the peripheral side. What is positioned is an opening edge side annular wire, and the end container and the ring shaped annular part are interconnected by inserting the opening edge side annular wire and the ring-shaped annular part through a ring member. It is.

  In the crane lifting tool according to the present invention, the long member is hooked to a pair of end housings each housing each housing end from each end to a predetermined length, and a hook of the crane. A latching portion is formed at one end, and the other end is composed of a pair of suspension members attached to each end container, and the end container is formed with an opening into which the housing end of the long member is inserted. And the bottom part which each edge part of an elongate member contact | abuts by the end surface is formed.

  In order to suspend a long member using the crane lifting tool according to the present invention, each housing end of the long member is inserted into each opening formed in a pair of end housings, and the housing Each end is accommodated in an end container.

  If it does in this way, a pair of end part container will be covered on both accommodation end parts of a long member in the direction which counters.

  Next, the latching portions provided at one ends of the respective suspension members are respectively latched on the hooks of the crane. Here, the other ends of the pair of suspension members are respectively attached to the pair of end housings.

  Next, by operating the crane, the long member that is a suspended load is suspended through a crane lifting tool including a pair of suspension members and a pair of end portions.

  In this way, the long member is suspended by two-point suspension by the crane suspension, and the tension according to the magnitude of the load of the long member and the suspension angle formed by the pair of suspension members is different. Although it arises in a suspension member, in this invention, among the tension | tensile_strength which arises in each suspension member, a horizontal component force acts on a pair of edge part container in the direction which mutually faces.

  Here, since the bottom portion is formed in the end portion container so that each end portion of the elongate member comes into contact with the end surface thereof, the horizontal component force acting on the end portion container is the end portion. It acts on each end of the elongate member that comes into contact with the bottom through the bottom of the part container.

  That is, of the tension generated in the pair of suspension members, the horizontal component force acts so that each end of the long member is pushed into the end container, and thus the long member Regardless of the position of the center of gravity, there is no possibility that both the receiving end parts will fall off from the pair of end part receiving bodies, and it will be suspended in a stable posture, and it is possible to prevent a situation where the long member slides down. It becomes. Needless to say, the long member is suspended in such a manner that the vertical component force acting on the pair of end portions is balanced with the load of the long member.

  The pair of end container described above has such a length that the long member does not fall off in a state in which each end of the long member is in contact with each bottom, and the long member is suspended. Of the tension generated in each of the pair of suspension members, it is configured to maintain sufficient strength against the horizontal component force, that is, the force pressing the bottom of the end container against the end surface of the long member. That's fine. For example, it is conceivable to use a wire or a reinforcing bar.

  Moreover, what is necessary is just to comprise so that a pair of edge part container and a pair of suspension member attached to them may have the intensity | strength which can support the component force of the perpendicular direction which acts on an edge part container.

  As long as the pair of end housings and the pair of suspension members have such a configuration, the structure, shape, material, and the like thereof are arbitrary. Here, the suspension member is composed of a wire rope, and the wire rope A ring-shaped annular portion in which a shackle or eye is provided at the other end, and at least the vicinity of the opening is made of a flexible material, and one end of the wire rope is inserted into the shackle or eye. By attaching to the vicinity of the opening of the end container, the opening can be contracted as the inner diameter of the ring-shaped annular portion is reduced as the crane is suspended.

  In such a configuration, each receiving end of the long member is inserted into a pair of end receiving bodies in which a ring-shaped annular portion in which one end of the wire rope is inserted into a shackle or eye is attached in the vicinity of the opening.

  In such a state, when one end of the wire rope is hooked on the hook of the crane and the long member is suspended, the tension due to the load of the long member is generated in each suspension member as the crane is suspended, and the ring is caused by the tension. The inner diameter of the ring-shaped annular portion is reduced, but the opening of each end container is configured to be retractable as the inner diameter of the ring-shaped annular portion is reduced. It is squeezed at the opening of each end container.

  That is, when the long member is suspended using the crane lifting tool according to the present invention, the housing end of the long member is restrained by the ring-shaped annular portion provided in the opening of the end container. Thus, it is possible to more reliably prevent the long member from sliding off, and it is possible to suspend the long member in a stable state without previously bundling a plurality of long members.

  The above-described end container can be configured to form an opening by joining a cylindrical cloth or wire formed of a flexible material to, for example, a reinforcing bar. In such a configuration, the bottom of the reinforcing bar rod corresponds to the bottom of the end container.

  Here, the end container is composed of a bottom portion and a cylindrical body connected to the bottom portion, and the bottom portion is knitted in a lattice shape so that the overall shape is substantially circular, and the plurality of bottom portions Each end of the wire is knitted into the bottom peripheral wire, and the cylindrical body is arranged by concentrically arranging a plurality of annular wires with different diameters, and knitting a plurality of vertical wires that are substantially orthogonal to them into the annular wire vertically and horizontally, respectively. The cylindrical wire stands up with respect to the bottom by inserting the bottom-side annular wire and the bottom peripheral edge wire into the ring member with the annular wire having the smallest diameter and located on the center side among the annular wires. While freely connecting, among the annular wires, the one with the largest diameter and located on the peripheral side is the opening edge side annular wire and the opening edge side annular wire and the front It can be configured to interconnect the ring annular portion end receptacle and a by inserting the ring member and the ring-shaped annular portion.

  When the cylindrical body is not used as a lifting tool, it becomes a donut-shaped expansion in the same plane around the bottom, and the whole body can be rolled up and stored or transported, and when used as a lifting tool Is formed along the peripheral edge of the bottom to form a space that can accommodate the end of the long member together with the bottom.

  As described above, the cylindrical body is configured by concentrically arranging a plurality of annular wires having different diameters and knitting a plurality of vertical wires substantially orthogonal to the annular wires vertically and horizontally, respectively. In the state in which the end portion is accommodated, the overall shape is a truncated cone.

  DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments of a crane lifting tool according to the present invention will be described with reference to the accompanying drawings. Note that components that are substantially the same as those of the prior art are assigned the same reference numerals, and descriptions thereof are omitted.

  FIG. 1 is a perspective view showing a crane suspension 10 according to the present embodiment.

  As can be seen from the figure, the crane lifting tool 10 according to the present embodiment accommodates each accommodating end portion from each end portion to a predetermined length among the plurality of single tubes 8 that are long members. A pair of end receptacles 1, 1 and eyes 3, 3, which are latching portions hooked on a crane hook 9, are formed at one end, and the other end is attached to each end receptacle 1, 1. The end housing 1 includes an opening 19 into which the housing end of the single tube 8 is inserted and each end of the single tube 8. Is formed with a bottom portion 5 which is in contact with the end face.

  FIG. 2 shows a plan view of the end container 1 with the opening 19 widened. As can be seen from the figure, the end container 1 is formed by weaving a wire, which is a flexible material, and includes a bottom 5 and a cylinder 12 connected to the bottom.

  Here, the bottom 5 constituting the end container 1 has a bottom peripheral edge in which a plurality of bottom wires 31 are knitted in a lattice shape so that the overall shape is substantially circular, and each end of the plurality of bottom wires 31 is positioned at the periphery. Each is knitted into the wire 32.

  The lattice-like mesh formed by the plurality of bottom wires 31 is adjusted so that the single tube 8 does not fall out of the mesh. For example, if the thickness of the single tube 8 is 48.6 mm, the bottom wire 31 is adjusted. It is only necessary to braid each in a lattice shape so that the thickness of the mesh is 6 mm and the mesh is 47 mm.

  Moreover, the cylinder 12 which comprises the edge part container 1 is concentric about four annular wires from which a diameter differs, ie, the bottom part side annular wire 34, the two annular wires 35 and 36, and the opening edge part side annular wire 11. A plurality of vertical wires 37 that are respectively arranged in a shape and are substantially orthogonal to them are braided vertically and horizontally.

  For example, among the bottom-side annular wire 34, the two annular wires 35 and 36, and the opening edge-side annular wire 11, the outer diameter of the bottom-side annular wire 34 having the smallest diameter and located on the center side is set to 1000 mm, The outer diameters of the annular wires 35 and 36 may be 1200 mm and 1400 mm, respectively, and the outer diameter of the opening edge side annular wire 11 having the largest diameter and located on the peripheral side may be 1600 mm.

  Here, one end of each vertical wire 37 is knitted into the bottom-side annular wire 34, and the other end is knitted into the opening edge-side annular wire 11.

  The vertical wire 37 is configured to have such a length that the single tube 8 does not fall out of the end container 1 with the end of the single tube 8 in contact with the bottom 5. For example, when the length of the single tube 8 is 4000 to 6000 mm, the vertical wire 37 may be about 300 mm.

  On the other hand, as can be seen from the plan view shown in FIG. 3, the wire rope 2 has an eye 4 formed at the other end and a ring-shaped annular portion 7 formed by inserting one end of the wire rope 2 into the eye. The ring-shaped annular portion is attached to the opening edge of the end container 1.

  Here, the opening edge side annular wire 11 and the ring-shaped annular portion 7 of the cylindrical body 12 are connected to each other by inserting them into the ring member 6.

  The number and arrangement of the ring member 6 are appropriately determined so that the opening edge side annular wire 11 and the ring-shaped annular portion 7 are evenly connected along the circumference. In addition, since the movement range of the ring member 6 is limited by the vertical wire 37 of the cylindrical body 12, the opening edge side annular wire 11 and the ring-shaped annular portion 7 are unevenly connected if the arrangement location is appropriately selected. There is no concern about being.

  As described above, in the ring member 6, the opening edge side annular wire 11 and the ring-shaped annular portion 7 are inserted, but when the ring-shaped annular portion 7 is squeezed, the ring-shaped annular portion is inside the ring member 6. In consideration of the thickness of the opening edge side annular wire 11 and the ring-shaped annular portion 7, the shape and inner diameter thereof are determined.

  For example, if the opening edge side annular wire 11 has a thickness of 12 mm and the ring-shaped annular portion 7 has a thickness of 16 mm, the ring member 6 may have an elliptical shape and the inner diameter in the major axis direction may be 50 to 60 mm. .

  Similarly, the bottom peripheral wire 32 constituting the bottom 5 and the bottom-side annular wire 34 constituting the cylinder 12 are inserted into the ring member 33 so that the cylinder 12 can stand up with respect to the bottom 5. They are interconnected.

  The number, position, shape, and dimensions of the ring member 33 may be determined in the same manner as the ring member 6.

  FIG. 4 shows the end container 1 in a state in which the single tube 8 can be stored by raising the cylindrical body 12 to the periphery of the bottom 5, and the opening edge side annular wire 11 and the ring of the cylindrical body 12. It is the perspective view which showed a mode that the annular shape part 7 was mutually connected by inserting in the ring member 6. FIG.

  In suspending the single pipe 8 using the crane lifting tool 10 according to the present embodiment, the bottom 5 and the cylinder 12 are first raised by raising the cylinder 12 of the end container 1 around the bottom 5. Then, an appropriate number of ends of the single tubes 8 are inserted into the accommodation space of the end container 1 from the opening 19 on the release side of the cylindrical body 12.

  At this time, by pulling one end of the wire rope 2 in parallel with the insertion operation of the single tube 8, the openings 19 of the end container 1 are narrowed to restrain the plurality of single tubes 8.

  After the same operation is performed on the opposite side of the single pipe 8, the eyes 3 and 3 respectively provided at one ends of the wire ropes 2 and 2 are respectively hooked on the hooks 9 of the crane.

  Next, the single pipe 8 which is a suspended load is suspended by operating the crane through a crane lifting tool 10 including a pair of wire ropes 2 and 2 and a pair of end portion accommodating bodies 1 and 1.

  If it does in this way, a plurality of single pipes 8 will be suspended by two-point suspension by crane suspension 10, and the magnitude of the load of single pipe 8 and the hanging angle formed by a pair of wire ropes 2 and 2 will be increased. The corresponding tension is generated in each wire rope 2, 2, but in the present embodiment, of the tension generated in each wire rope 2, 2, the pair of end housings 1 in the direction in which the horizontal component forces face each other. Act on 1.

  Here, since each end container 1, 1 is formed with a bottom part 5, 5 with which each end part of the single tube 8 abuts on its end surface, each end container 1, 1. The horizontal component force acting on the bottom acts on each end portion of the single tube 8 contacting the bottom portion via the bottom portions 5 and 5 of the end portion container.

  Further, the inner diameter of the ring-shaped annular portions 7 and 7 is reduced by the tension caused by the load of the single tube 8 generated in each wire rope 2 and 2. Since the opening 19 and 19 of 1 is configured to be retractable, the receiving ends of the single tubes 8 and 8 are narrowed down by the openings 19 and 19 via the wire ropes 2 and 2, respectively, and are firmly restrained. Is done.

  As described above, according to the crane lifting tool 10 according to the present embodiment, among the plurality of single pipes 8, each accommodation end from each end to a predetermined length is used as the end container 1, 1. Since the plurality of single tubes 8 are suspended by the wire ropes 2 and 2 attached to the end containers 1 and 1 in such a state, of the tension generated in the pair of wire ropes 2 and 2. The horizontal component force acts so as to press the bottoms 5 and 5 of each end container 1 and 1 against each end face of the single tube 8.

  Therefore, the plurality of single tubes 8 can be suspended in a stable posture without the possibility that the respective housing end portions will fall out of the pair of end portion housings 1 and 1 regardless of the positions of their center of gravity. Even if the 8 is not bundled in advance, it is possible to prevent the single tube 8 from sliding down.

  Moreover, according to the crane lifting tool 10 which concerns on this embodiment, the ring-shaped annular parts 7 and 7 by which the end of the wire ropes 2 and 2 are penetrated by the eyes 4 and 4 are made into opening of the end container 1 and 1. Since the openings 19 and 19 are configured to be retractable as the inner diameters of the ring-shaped annular portions 7 and 7 accompanying the crane suspension are reduced by being attached to the cranes 19 and 19, the tension associated with the crane suspension is reduced. When the wire ropes 2 and 2 are generated, the inner diameters of the ring-shaped annular portions 7 and 7 are reduced due to the tension, and the openings 19 and 19 of the end accommodating bodies 1 and 1 are contracted to accommodate the individual tubes 8. Narrow down the edges.

  Therefore, it becomes possible to narrow down the accommodating ends of the single tubes 8 and 8 through the openings 19 and 19 of the end accommodating bodies 1 and 1, respectively, and firmly restrain the single tubes 8 and 1 to prevent the single tube 8 from sliding down more reliably. In addition to this, the need to bundle a plurality of single tubes 8 in advance is further reduced.

  In this embodiment, when attaching the ring-shaped annular part 7 to the opening edge side annular wire 11 of the end container 1, the ring member 6 is interposed, but the ring member is omitted and the end part is accommodated. Ring-shaped annular portion directly on a plurality of meshes located at the opening edge of the body 1, that is, the plurality of meshes surrounded by the opening edge-side annular wire 11, the annular wire 36 and the two adjacent vertical wires 37, 37 7 may be entangled.

  Further, in the present embodiment, the ring-shaped annular portion 7 is formed by inserting one end into the eye 4 provided at the other end of the wire rope 2, but in the perspective view of the wire rope 2 shown in FIG. As can be seen, an eye 41 is provided at the other end of the wire rope, and the pin is screwed into the pin hole 43 of the shackle body 42 so that the pin 44 of the shackle 45 is inserted into the eye, and then one end of the wire rope 2 is inserted. May be inserted into the shackle 45 to form a ring-shaped annular portion 7 '.

  In this embodiment, the end container 1 is knitted with a wire, that is, the entire end container is made of a flexible material, but the entire end container is necessarily made of a flexible material. There is no need, and it is sufficient if only the vicinity of the opening is made of a flexible material such as a wire or cloth. Even in such a configuration, each end of the inserted long member can be squeezed and restrained.

  For example, a cylindrical cloth or wire formed of a flexible material can be joined to, for example, a reinforcing bar to form the vicinity of the opening. In such a configuration, the bottom of the reinforcing bar rod corresponds to the bottom of the end container.

  Although not particularly mentioned in the present embodiment, the pair of end container according to the present invention is configured such that each end of a long member such as a single tube is in contact with the bottom. Of the tension generated in the pair of suspension members when the long member is suspended, the horizontal component of the tension, that is, the bottom of the end container, is the length of the elongated member. Any member may be used as long as it is configured to maintain a sufficient strength against the force to be pressed against the end surfaces, and the pair of end portions and the pair of suspension members attached thereto are end members. What is necessary is just to comprise so that it may have the intensity | strength which can support the vertical component force which acts on a part container, and it is not limited to the end container 1,1 of this embodiment, or the wire rope 2. FIG.

  For example, instead of the end container 1, a bottomed cylindrical body formed of a hard material may be used as the end container, or a bag made of a cloth having high tensile strength may be used as the end container. Can do. In these cases, the other end of the suspension member may be attached at a predetermined position of the opening edge.

  Further, as described above, the ring-shaped annular portion 7 may be attached to the opening edge portion of the bag body made of a cloth that is a flexible material in the same manner as in the above-described embodiment.
