Description

[Technical field]

[0001] The present invention relates to a pillar suspending jig for suspending a pillar when erecting the pillar, and more particularly to a pillar suspending jig that can be easily attached to a pillar and can securely hold the pillar. [Background technology]

[0002] Conventionally, the erection of columns has generally been achieved by suspending the top of the column (column capital) using a lifting device such as a crane. This method requires the column to be fixed with an anchor bolt, and then the wire attached to the top of the column must be removed. However, this work must be done at a high altitude, so a column suspension device has been proposed that aims to eliminate the need for work at a high altitude and improve safety.

[0003] Patent Document 1 proposes a column suspension device that includes an upper end fitting equipped with a hook hanger that is suspended by a crane, a frame-shaped head connected via a wire to the lower part of the upper end fitting, a lower end fitting connected via a wire whose length can be adjusted by a turnbuckle to the lower part of the head, and a locking fitting that is detachably attached to the lower end fitting and fixed to the lower side of the column. With this column suspension device, attachment and detachment to the column is performed on the lower side of the column, which improves safety by eliminating the need for work at height.

[0004] [Patent Document 1] Japanese Patent Application Publication No. 6-272386 Summary of the Invention [Problem to be solved by the invention]

[0005] In the pole suspension device described in Patent Document 1, when attaching the lower end fitting connected to the wire to the locking fitting, a bolt is inserted from below the lower end fitting to tighten the locking fitting. Therefore, a tool is required for installation, and it is time-consuming and laborious to attach and detach the lower end fitting.

[0006] The present invention has been made in consideration of the above problems, and an object of the present invention is to provide a pole suspension jig that is easy to attach to a pole and can securely hold the pole and erect it for suspension. Another object of the present invention is to provide a fixture that is easy to attach to a pole. [Means for solving the problem]

[0007] The above problem is solved by the column lifting jig of the present invention, Lifting material A pole suspending jig for suspending a pole provided with an engagement portion, Lifting material and a frame-shaped head member surrounding the head portion of the column, a connecting member extending from the head member, and a fastener disposed below the head member, connected to the connecting member, and removably fixed to the engaging portion of the column, the engaging portion being provided on the side surface of the column and having openings at the upper and lower ends, and the fastener extending from the head member. The above The operating member has a base which connects to a connecting member, a first engaging portion having a first engaging piece formed thereon to be inserted into an opening at a lower end of the engaging portion, a second engaging portion having a second engaging piece formed thereon to be inserted into an opening at an upper end of the engaging portion and being movable in an up-down direction relative to the base, and an operating member connected to the second engaging portion and moving the second engaging portion in an up-down direction, the operating member having an operating head at an upper end and an operating shaft portion connected to the operating head and having a screw portion formed therein, a screw hole penetrating in the up-down direction is formed in the base, and the screw portion of the operating member is screwed into the screw hole of the base, and the problem is solved by the second engaging piece moving in the up-down direction when the operating head is rotated.

[0008] The pole suspension jig of the present invention configured as described above can move the second locking part up and down by a simple operation of rotating the operating member screwed into the screw hole in the base of the fixture. Furthermore, because the operating member screwed into the screw hole in the base, the second locking piece of the second locking part is prevented from coming off the engagement part of the pole. Therefore, the fixture can be easily attached to the pole, and the pole can be securely held and erected for suspension.

[0009] In this case, the operating shaft portion may have a non-threaded portion on the lower side of the threaded portion where no thread groove is formed, and the length of the threaded portion in the vertical direction may be shorter than the length of the non-threaded portion. In the above configuration, the amount of operation of the operating member relative to the screw hole in the base is less than when a threaded portion is formed over the entire operating shaft portion, and therefore the time required to fix the wire fixing device to the engagement portion is shorter.

[0010] In this case, the fixing device has a support member connected to the second engagement portion and supporting the second engagement portion, the support member having a support head at an upper end and a support shaft portion connected to the support head, and the base portion has a loose hole formed therein that penetrates in the vertical direction, and the support shaft portion is inserted into the loose hole in the base. In the above configuration, the support shaft portion of the support member supporting the second engagement portion is inserted into the loose hole in the base of the fixing device, thereby stabilizing the vertical movement of the second engagement portion by operating the operating member.

[0011] In this case, it is preferable that the operating head has a polygonal outer shape, and the supporting head has a circular outer shape. In the above configuration, when the second locking portion is moved in the vertical direction, the operating head to be operated can be identified, and the polygonal operating head can be rotated using an instrument (tool) such as an adjustable wrench or hexagonal socket wrench, making it possible to properly engage the second locking portion with the engagement portion.

[0012] In this case, the connecting member is formed by connecting a first connecting member and a second connecting member, the first connecting member has an upper end connected to the head member, the second connecting member has an upper end connected to the first connecting member and a lower end connected to the fixing device, and the second connecting member is preferably adjustable in length. In the above configuration, by adjusting the length of the second connecting member, it is possible to accommodate pillars of different heights.

[0013] In this case, a receiving portion may be formed on the side surface of the head member from the lower end toward the upper end, and the receiving portion may be capable of receiving an attachment provided on the column capital portion. In the above configuration, the frame-shaped head member surrounds the column head portion while being capable of receiving accessories provided on the column head portion in the receiving portion, making it possible to securely hold the column, erect it, and suspend it.

[0014] The above problem is solved by the fixing device of the present invention. When a column is suspended by a lifting member extending from a lifting device, the column is used together with a head member that is connected to the lifting member and holds the column head portion of the column, Attached to the side of the pillar hand A fastener that is removably fixed to an engagement portion having openings at upper and lower ends, Extending from the head member Connecting parts Bottom end of and an operating member connected to the second locking portion and configured to move the second locking portion in the vertical direction, the operating member having an operating head and an operating shaft portion connected to the operating head and configured to have a screw portion formed therein, the base having a screw hole penetrating in the vertical direction, the screw portion of the operating member being screwed into the screw hole of the base, and the second locking piece being moved in the vertical direction when the operating head is rotated.

[0015] The fixture of the present invention configured as described above allows the second engaging portion to be moved up and down by the simple operation of rotating the operating member screwed into the screw hole in the base, making it easy to attach the fixture to a pillar and enabling the pillar to be securely held and erected for hanging. Effect of the Invention

[0016] The pillar suspension jig of the present invention provides a pillar suspension jig that can be easily attached to a pillar and can securely hold the pillar and erect it for suspension. Furthermore, the fastener according to the present invention can provide a fastener that can be easily attached to a pole. [Brief description of the drawings]

[0018] A column suspension jig and fixture according to one embodiment of the present invention (hereinafter, this embodiment) will be described below with reference to Figures 1 to 10. In the following embodiments, the same or similar components are denoted by common reference symbols, and the scale of these drawings is appropriately changed for ease of understanding.

[0019] In the following description, as shown by the arrow in Fig. 1, the up-down direction means the up-down direction when the column suspension jig 10 is attached to the steel column 1 in an upright state. Furthermore, the front and back of the wire fixture 20 refer to the surface that faces the steel column 1 when the wire fixture 20 is fixed to the steel column 1 as the back surface, and the front surface refers to the surface opposite the steel column 1. Furthermore, the outside and inside are defined based on the steel column 1. In other words, the direction approaching the center of the steel column 1 is the inward direction, and the direction away from it is the outward direction.

[0020] [1. Configuration of the column suspension jig 10] 1 shows a steel column 1, which is a column, and a column hoisting jig 10 attached to suspend the steel column 1. The column hoisting jig 10 is used to lift the steel column 1, which is used in the framework of a building, from a temporarily laid-down state using a hoisting device, hoist it up, move it to a desired location, and then fix it in an upright state.

[0021] The column hoisting jig 10 is connected to a hoisting device, such as a crane (not shown), and erects a steel column 1. The column hoisting jig 10 includes a head member 12 (FIGS. 2A and 2B) and a pair of wire fixtures 20 (FIGS. 3 to 6).

[0022] The steel column 1 erected by the column hanging jig 10 is a steel column 1 with a rectangular cross section as shown in Figures 1 and 3, and a gusset plate 1b is attached to the column head 1a as an attachment. In addition, an engagement part 2 is attached to the side of the steel column 1, which is also used to set up a temporary work floor as scaffolding. The engagement part 2 is formed by bending a bent plate-like member as shown in Figures 1, 3, and 4A, and is configured by attaching it to the side of the steel column 1 by welding or the like.

[0023] Between the outer periphery of the steel column 1 and the engagement part 2, two gaps extending in the vertical direction are formed by bending, and two openings 2a, 2b are formed at each of the upper and lower ends. When setting up a work floor (not shown), a locking claw formed on the work floor is inserted into the upper opening 2a of the engagement part 2 to fix the work floor. The engagement parts 2 are provided at a predetermined interval in the vertical direction on each side of the steel column 1 so that work floors can be set up at several heights as shown in FIG. 1.

[0024] Since the engagement portion 2 for installing the work floor is welded, there is no need to provide holes on the side of the steel column 1 to attach a work floor or ladder, as was previously required. In addition, since the work of forming holes in the steel column 1 is time-consuming, it is preferable to use the engagement portion 2 of the steel column 1 that is provided in advance in order to hoist and move the steel column 1. In addition, since no holes are formed in the steel column 1, it is preferable that a higher strength can be obtained compared to when holes are formed.

[0025] A column plate 30 is provided at the lower end of the steel column 1 for fixing to a foundation 32. At the four corners of the column plate 30, through holes 30a are formed through which anchor bolts 33 (see FIG. 8D) for fixing the steel column 1 to the foundation 32 are passed.

[0026] <Head component 12> As shown in FIGS. 2A and 2B, the head member 12 of the column suspension jig 10 of this embodiment is a frame-shaped member, and in this embodiment, as shown in FIG. 1, is arranged so as to surround the column capital part 1a at the upper end of the steel column 1, and is connected to two wires 14 ( Lifting material As described below, the pair of wire fixtures 20 are disposed below the head member 12 and are connected to two wires 15 (connecting members) extending from the head member 12. Note that the wires 14, 15 serving as connecting members may be other connecting members such as slings or chains.

[0027] The length L of the wire 15 is set so that when the steel column 1 is erected, the head member 12 does not come off the column capital part 1a (upper end part) of the steel column 1. In other words, the position of the upper end of the wire 15 when the steel column 1 is erected is set so as to be lower than the height H of the steel column 1. The wire 15 is provided with a turnbuckle (not shown) in the middle part, making the length adjustable.

[0028] A stopper 13 is provided above the head member 12. The stopper 13 prevents the head member 12 from falling downward when a wire 14 extending from a crane comes off. In addition, a hook holder 12a is provided on a side surface 12b of the head member 12 for hanging a hook 18 provided on the end of the wire 14 and a hook 17 provided on the end of the wire 15.

[0029] (Slit 12c) A slit 12c is formed on each of the four side surfaces 12b (more specifically, the center of the side surfaces 12b) of the frame-shaped head member 12 as a receiving portion extending upward from the lower end of the head member 12. This slit 12c is capable of receiving a gusset plate 1b as an attachment provided on the column head portion 1a of the steel column 1. The length of the slit 12c is formed to be at least half the length of the gusset plate 1b in the extension direction of the steel column 1 (i.e., the vertical direction).

[0030] Accessories such as gusset plates 1b may be placed on the four side surfaces of the steel column 1, but the head member 12 provided in the column hanging jig 10 of this embodiment has slits 12c formed in each of the four side surfaces 12b, making it possible to accommodate cases where the number of accessories placed on the column head 1a of the steel column 1 and the combination of side surfaces on which the accessories are placed are different.

[0031] In the column suspension jig 10 according to this embodiment, the frame-shaped head member 12 surrounds the column capital part 1a of the steel column 1, while the gusset plate 1b, which is an accessory, can be received in the slit 12c. In other words, even in the case of a steel column 1 having an accessory at the column capital part 1a, the column capital part 1a can be securely held by the head member 12 having the slit 12c, and can be erected and suspended.

[0032] 1 and 2A, the slits 12c are formed to be longer than the length of the gusset plate 1b in the extension direction (i.e., the vertical direction) of the steel column 1. With this configuration, with the head member 12 surrounding the column head portion 1a of the steel column 1, the gusset plate 1b is stably received in the slits 12c in the extension direction of the steel column 1, so that the steel column 1 can be erected and suspended while the column head portion 1a of the steel column 1 is more reliably held.

[0033] 2B, on a side surface 12b of the head member 12, hook holders 12a serving as connecting parts to which the wires 14 and 15 are connected via hooks 17 and 18 are arranged point-symmetrically in a top view of the head member 12. More specifically, with respect to each slit 12c formed in the center of the opposing side surface 12b of the head member 12, a hook holder 12a is arranged on the opposite side in a top view.

[0034] According to such an arrangement of the hook holders 12a, it is possible to receive accessories in the slits 12c of the head member 12, while connecting the wires 14, 15 to the hook holders 12a in a well-balanced and appropriate manner.

[0035] In addition, slit 12c is formed so that it is wider than the thickness of gusset plate 1b and longer (deeper) than the vertical length of gusset plate 1b. Therefore, even if head member 12 tilts or steel column 1 rotates, gusset plate 1b will not come out of slit 12c, and the column head portion 1a of steel column 1 will be stably held by head member 12.

[0036] <Wire fixture 20> The pair of wire fixtures 20 (fixtures) provided in the column suspension jig 10 of this embodiment are attached to the side surfaces of the steel column 1 and are detachably fixed to the engagement parts 2 located in opposite directions. As described above, the wire fixture 20 is a jig that is detachably fixed to the engagement part 2 provided on the side part of the steel column 1, and has a base 21 that connects to the wire 15 extending from the head member 12, as shown in Figures 3 to 7. The base 21 is a metallic member formed into a rectangular plate shape, and is provided with side parts 22 that extend downward from both ends.

[0037] Further, the wire fastener 20 has a first locking portion 23 provided at a position a predetermined distance away from the base portion 21 by the side portion 22. A first locking piece 23a is formed at the upper end of the first locking portion 23 to be inserted into an opening 2b at the lower end portion of the engagement portion 2.

[0038] The wire fastener 20 has an operating member 25 and a supporting member 26. A second locking portion 24 is connected to the lower ends of the operating member 25 and the supporting member 26. The second locking portion 24 is connected to the operating member 25 and the supporting member 26, which will be described later, and is movable in the vertical direction relative to the base 21. When the wire fastener 20 is attached to the engaging portion 2, the operating member 25 is operated (rotated) to move the second locking portion 24 downward (in the direction of arrow B in FIG. 5) from the base 21 toward the engaging portion 2. The second locking portion 24 has a second locking piece 24a formed at its lower end, which is inserted into an opening 2a at the upper end of the engaging portion 2.

[0039] 5, the vertical length of the lower first locking piece 23a is longer than the vertical length of the upper second locking piece 24a. Since the first locking piece 23a inserted into the engaging part 2 from below is formed long, the first locking piece 23a is less likely to come off the opening 2b at the lower end of the engaging part 2, so that the attachment state of the wire fastener 20 to the engaging part 2 of the steel column 1 is stable.

[0040] As shown in Fig. 3 to Fig. 7, the operating member 25 has an operating head 25a at the upper end, an operating shaft 25b (a threaded shaft member) connected to the operating head 25a and having a threaded portion 25b1 and a non-threaded portion 25b2, and a nut 25c attached to the lower end of the operating member 25. A screw hole 21a penetrating in the vertical direction is formed in the base 21 of the wire fixing device 20, and a screw portion 25b1 formed on the operating shaft 25b of the operating member 25 is screwed into this screw hole 21a. A nut 25c is attached to the lower end side of the operating member 25, and the operating member 25 is rotatably held relative to the second locking portion 24. When the operating head 25a is rotated, the second locking piece 24a moves in the vertical direction.

[0041] As shown in FIG. 4B, the operating shaft portion 25b includes, in order from the upper side, an operating head portion 25a, a threaded portion 25b1 (a threaded portion where a thread groove is formed), and a non-threaded portion 25b2 (a non-threaded portion where no thread groove is formed). The length N1 of the threaded portion 25b1 in the vertical direction is shorter than the length N2 of the non-threaded portion 25b2 in the vertical direction (N1 < N2). According to such a configuration, compared with the case where a threaded portion is formed over the entire operating shaft portion 25b, the operating amount (the amount of turning the screw) of the operating member 25 with respect to the screw hole 21a of the base portion 21 is reduced (that is, since the distance of screwing is shortened), the working time for fixing the wire fixture 20 to the engaging portion 2 is shortened. Note that the length N1 of the threaded portion 25b1 substantially coincides with the height (depth) of the screw hole 21a of the base portion 21 (in other words, the length N1 of the threaded portion 25b1 may be about the same as the plate thickness of the base portion 21 in the vertical direction (for example, ±10% of the plate thickness of the base portion 21 in the vertical direction, preferably ±5%, more preferably ±3%, still more preferably ±2%, and even more preferably ±1%)). Further, since the non-threaded portion 25b2 is formed by cutting the central portion of the bolt, the thickness of the non-threaded portion 25b2 is thinner than that of the threaded portion 25b1.

[0042] As shown in FIGS. 3 to 7, the support member 26 has an upper support head portion 26a, a support shaft portion 26b connected to the support head portion 26a, and a nut 26c attached to the lower end of the support member 26. A loose hole 21b (a through hole where no threaded portion is formed) penetrating in the vertical direction is formed in the base portion 21 of the wire fixture 20, and the support shaft portion 26b of the support member 26 is inserted into the loose hole 21b. Further, a nut 26c is attached to the lower end side of the support member 26 and is held with respect to the second locking portion 24.

[0043] When attaching the wire fastener 20 to the steel column 1, the worker rotates the operating head 25a of the operating member 25 to push the second locking portion 24 of the wire fastener 20 upward (in the direction of the arrow A in FIG. 4A ) as shown in FIG. 4A . With the second locking portion 24 positioned upward, the distance D1 between the tip of the first locking piece 23a and the tip of the second locking piece 24a becomes longer than the length L1 of the engagement portion 2 in the up-down direction. Therefore, the engagement portion 2 can be positioned between the first locking portion 23 and the second locking portion 24.

[0044] After arranging the engaging portion 2 between the first locking portion 23 and the second locking portion 24, the operator rotates the operating head 25a of the operating member 25 using a tool such as a wrench to move the second locking portion 24 downward (in the direction of arrow B in FIG. 5). In this way, the first locking pieces 23a of the first locking portion 23 are inserted into the openings 2b on the lower end side of the engaging portion 2, and the second locking pieces 24a of the second locking portion 24 are inserted into the openings 2a on the upper end side of the engaging portion 2.

[0045] 5, the distance D2 between the tip of the first locking piece 23a and the tip of the second locking piece 24a is shorter than the length L1 of the engagement part 2. Since the screw part 25b1 formed on the operation shaft part 25b of the operation member 25 is screwed into the screw hole 21a formed in the base part 21, the operation member 25 and the support member 26 do not move freely relative to the base part 21. In other words, the screw part 25b1 formed on the operation shaft part 25b of the operation member 25 and the screw hole 21a formed in the base part 21 constitute a lock mechanism that prevents the second locking part 24 (the second locking piece 24a) from moving up and down. With this configuration, the first locking piece 23a and the second locking piece 24a are less likely to come off the upper and lower openings 2a, 2b of the engagement part 2, and the wire fixing device 20 can be reliably fixed to the engagement part 2.

[0046] Also, an operator can move the second locking portion 24 up and down by a simple operation of rotating the operating member 25 screwed into the screw hole 21a of the base 21 of the wire fastener 20. Furthermore, because the operating member 25 screwed into the screw hole 21a of the base 21, the second locking piece 24a of the second locking portion 24 is prevented from coming off the engaging portion 2 of the steel column 1. Therefore, the wire fastener 20 can be easily attached to the steel column 1, and the steel column 1 can be securely held, erected, and suspended.

[0047] The wire fastener 20 also has a support member 26 connected to the second fastening portion 24 and supporting the second fastening portion 24, the support member 26 having a support head 26a at the upper end and a support shaft portion 26b connected to the support head 26a. The base portion 21 of the wire fastener 20 is formed with a loose hole 21b penetrating in the vertical direction, and the support shaft portion 26b is inserted into the loose hole 21b. In this way, the second fastening portion 24 is supported by the support member 26 inserted into the loose hole 21b of the base portion 21, and therefore the support member 26 exerts a guide function, so that the movement of the second fastening portion 24 in the vertical direction due to the operation of the operating member 25 is stabilized.

[0048] Moreover, the operation head 25a has a polygonal outer shape (hexagonal in this embodiment), and the support head 26a has a circular outer shape. In this configuration, when moving the second locking part 24 in the vertical direction, the operator can distinguish the operation head 25a to be operated. Then, the operator can rotate the polygonal operation head 25a using an instrument (tool) such as an adjustable wrench or a hexagonal socket wrench to sufficiently move the second locking part 24 downward, so that the second locking part 24 can be appropriately engaged with the engagement part 2.

[0049] The base 21 also has a ring-shaped portion 27 for hooking the hook 16 provided at the lower end of the wire 15 extending from the head member 12. The ring-shaped portion 27 is fixed to the upper surface of the base 21. The ring-shaped portion 27 may be fixed to the base 21 so as to be rotatable in the direction of arrow D in Fig. 7, with the vertical direction as the central axis. By attaching the ring-shaped portion 27 so as to be rotatable, even if the wire 15 is twisted after the hook 16 is hooked, the twist can be eliminated by rotating the ring-shaped portion 27.

[0050] In this embodiment, two first locking pieces 23a of the first locking portion 23 and two second locking pieces 24a of the second locking portion 24 are provided, but one first locking piece 23a and one second locking piece 24a may be provided, or three or more first locking pieces 23a and second locking pieces 24a may be provided in accordance with the number of openings 2a, 2b of the engagement portion 2. By providing a plurality of first locking pieces 23a and second locking pieces 24a, the wire fastener 20 can be stably attached to the engagement portion 2 without being tilted.

[0051] [2. How to erect and install a pillar using the pillar hanging jig 10] 8A to 8D show the column suspension jig 10 of this embodiment in use. As shown in Fig. 8A, the column suspension jig 10 is attached to a steel column 1 that is temporarily placed on a sleeper 31 in a horizontal state. First, the head member 12 is attached so as to cover the column head portion 1a that will be at the top when the steel column 1 is erected. At this time, the gusset plate 1b provided on the column head portion 1a of the steel column 1 is received in the slit 12c formed in the side surface 12b of the head member 12.

[0052] After the head member 12 is attached, the head member 12 and the wire fixture 20 are connected by the wire 15. If hooks 16, 17 having hook mechanisms are provided on both ends of the wire 15, the wire 15 can be easily attached to the head member 12 and the wire fixture 20. Then, following the procedure described above, the wire fixture 20 is attached to the engagement part 2 that will be located below when the steel column 1 is erected. At this time, the length of the wire 15 is adjusted appropriately by operating a turnbuckle (not shown) provided on the wire 15.

[0053] Next, the head member 12 is connected to a crane (lifting device) via a wire 14. Then, the crane is operated to lift the head member 12. As shown in FIG. 8B, when the head member 12 is lifted, the steel column 1 gradually stands up. The crane continues lifting until the steel column 1 is erected.

[0054] After the steel column 1 is erected, as shown in Fig. 8C, the steel column 1 is lifted up by a crane and moved to a place where the steel column 1 is to be installed. After the steel column 1 is moved to the foundation 32 where it is to be installed, the steel column 1 is lowered and the anchor bolt 33 is inserted into the through hole 30a of the column plate 30 of the steel column 1 to fix it to the foundation 32, as shown in Fig. 8D.

[0055] Then, the operating head 25a of the operating member 25 is rotated using a tool such as a wrench to move the second locking portion 24 upward, and the second locking piece 24a is disengaged from the upper opening 2a of the engagement portion 2. In this manner, the wire fastener 20 is removed from the engagement portion 2 of the steel column 1. Because the worker can move the second locking portion 24 (second locking piece 24a) of the wire fastener 20 up and down by the simple operation of rotating the operating head 25a of the operating member 25, the wire fastener 20 can be easily attached and detached without time or effort.

[0056] Next, the connection between the hook 16 of the wire 15 and the wire fixture 20 is released, and then the head member 12 is further hoisted by a crane and removed from the column capital 1a of the steel column 1. Since the head member 12 simply covers and surrounds the column capital 1a of the steel column 1, it can be removed simply by hoisting it upwards (in the direction of arrow D in Fig. 8D) with a crane. The work of removing the column hoisting jig 10 by a worker is performed below the steel column 1, so there is no need to work at height and it is safe.

[0057] [3. Modifications] The column suspension jig of the present invention has been described above using one embodiment as an example regarding its configuration and method of use. However, the above-described embodiment is merely one example, and other examples are also contemplated.

[0058] A column suspension jig 10X according to a modified example is shown in Figures 9 and 10. The column suspension jig 10X according to the modified example differs in the state of the wire 15 between the head member 12 and the wire fixture 20 described above. Below, a description of the same configuration as the column suspension jig 10 described above will be omitted, and the following description will focus on the differences.

[0059] As shown typically in Fig. 9, a column suspension jig 10X according to a modified example has a connecting member in which an upper connecting member 15Xa and a lower connecting member 15Xb are connected between a head member 12 and a wire fastener 20. The upper end of the upper connecting member 15Xa is connected to the head member 12. The upper end of the lower connecting member 15Xb is connected to the upper connecting member 15Xa via an upper hook 16Xa, and the lower end is connected to the annular portion 27 of the wire fastener 20 via a lower hook 16Xb. The length of the lower connecting member 15Xb is adjustable.

[0060] Specifically, as shown in FIG. 10, by using a length-adjustable chain sling as the lower connecting member 15Xb, the column suspending jig 10X can be used to support steel columns 1 of different heights.

[0061] In this case, it is preferable that the upper connecting member 15Xa connected to the head member 12 is made of a wire sling, and the lower connecting member 15Xb is made of a chain sling whose length is adjustable. With this configuration, the upper connecting member 15Xa on the upper side, which is likely to be subjected to force when the head member 12 moves, is made of a wire sling that is resistant to tension, while the lower connecting member 15Xb, which is a chain sling, can be adjusted to an appropriate length, making it easier to attach the wire fastener 20 to the engagement portion 2.

[0062] In the above embodiment, an example has been given of a case where an accessory is provided to the column head 1a of the steel column 1, but the column hanging jig 10 can be used even if the column head 1a of the steel column 1 does not have an accessory such as a gusset plate 1b.

[0063] In the above embodiment, the column suspension jig and wire fixture according to the present invention have been mainly described. In the above embodiment, the steel column 1 was the target, but the column suspension jig may be used not only for the steel column 1 but also when erecting a wooden column. In addition, the column is not limited to a square column, but may be a round column. Similarly, the head member is not limited to a rectangular shape, but may be a circular shape, so long as it is frame-shaped.

[0064] Furthermore, the above-mentioned embodiment is merely an example for easily understanding the present invention, and is not intended to limit the present invention. The present invention can be modified or improved without departing from the spirit of the present invention, and the present invention naturally includes equivalents thereof.
