BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hardware for reversing a member for changing and reversing the posture of a member suspended by a lifting machine or the like.

[0002]

2. Description of the Related Art For example, in the case of performing a lifting operation in which various building materials are suspended and moved by a lifting machine,
Demands often arise to reverse the suspended material. In such a case, conventionally, the suspended material is temporarily dropped on the ground and temporarily placed, and then suspended again to have a desired posture, or a reversing jig incorporating a commercially available motor, winch, or the like. A method of reversing a suspended material by using a tool has been adopted.

[0003]

However, according to the former method, a plurality of fulcrums (hardware) need to be attached to the member in advance, so that the amount of work is increased and the number of fulcrums to each fulcrum is increased. Since it takes time and effort to attach and detach the hook, it is difficult to invert the member in a short time, and it is necessary to separately prepare a counterlift crane for the inversion, so that there is a problem that the cost is increased. In addition, the latter method has a problem that the cost of the reversing jig is high, which causes an increase in cost.
Furthermore, in the case of using a commercially available reversing jig, it is necessary to temporarily remove the hook for reversing the member, so that there is a problem that it is not possible to re-suspend in the air in a place where there is no counter lift machine. I have.

An object of the present invention is to reverse a member suspended by a hoist or the like in a short time without changing the hanging posture of the hoist without removing and attaching a hook of the hoist. In providing hardware.

[0005]

A feature of the present invention to solve the above-mentioned problem is a member for reversing a member for changing the posture of a member suspended by a hoist, wherein the metal member is provided on a surface of the member. A rail provided with a support guide groove, and a suspension piece mounted on the rail so as to be movable while being supported and guided by the support guide groove. A fixture for fixing the hanging piece to the rail at a desired position of the support guide groove; a spacer for securing a required space between the rail and the member; A fastener for fastening the rail to the member with the required space secured between the rail and the member.

[0006] The corner of the rail is preferably formed in an arc shape so that the suspension piece can move smoothly along the support guide groove. In order to be able to fix the suspension piece to the rail at any position in the support guide groove, a leg with a thread groove is provided at the lower end of the suspension piece, and this leg is passed through the support guide groove to make the groove width. A larger nut may be attached to the leg. If the nut is loosened, the hanging piece can move freely along the support guide groove without coming out of the support guide groove by the nut.The nut can be loosened at any place to fix the hanging piece to the rail. Can be.

The fastening fitting for fixing the rail to the member is a plurality of sets of bolts and nuts in which the rail and the member are tightened by bolts and nuts using a through hole provided in the rail. Can be.

[0008] The hanging piece can be fixed to a rail at a required position by a fixture, and the hanging piece can be directly or indirectly hung on a hook of a hoist to lift the member. Here, if it is desired to change the posture of the lifted member, the member is first landed on the ground, and the fixing between the hanging piece and the rail is released while the hanging piece and the hook are connected, The hanging piece is moved to a required location along the support guide groove of the rail, and is again fixed to the rail by the fixture. If the member is lightweight, the above operation may be performed in the air without lowering the member to the ground.

If the fixing position of the hanging piece is changed,
If the member is lifted again by the lifting machine, the posture of the lifted member changes according to the fixing position of the hanging piece to the rail, whereby the posture of the member can be changed and the member can be turned over.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a plan view showing a state in which a metal 10 for reversing members according to the present invention is attached to a member 1 to be hung by a lifting machine (not shown). FIG. 2 is a front view of the metal body 10 showing a cross section of the member 1. 3 is a left side view of the hardware 10.

The hardware 10 will be described below with reference to FIGS. The metal fitting 10 includes a rail 11 formed by forming a slightly thick band-shaped member made of iron or other metal material into a substantially L-shape. The rail 11 is provided on the upper surface 1A of the member 1.
And a second portion 11B arranged along one side surface 1B connected to the upper surface 1A of the member 1, and a second portion 11B is arranged from the second portion 11B.
A third portion 11C is formed which extends substantially perpendicular to the portion 11B and is fixed to the lower surface 1C of the member 1 as described later. A corner portion 11D between the first portion 11A and the second portion 11B is curved so as to draw an arc.

A support guide groove 1 extending along the length of the rail 11 is formed substantially at the center of the rail 11 formed as described above.
2 are formed. The support guide groove 12 is a relatively narrow groove having a constant width, and is formed to extend from the middle of the first portion 11A to the lower portion of the second portion 11B through the corner portion 11D.

The first portion 11A of the rail 11 is arranged at a substantially constant distance from the upper surface 1A of the member 1, and the first portion 11A and the upper surface 1A are substantially parallel.
A plurality of spacers 13 are provided at appropriate intervals between the first portion 11A and the upper surface 1A. On the other hand, rail 11
The second portion 11B is also disposed at a substantially constant interval from one side surface 1B of the member 1, and the second portion 11B is arranged so that the second portion 11B and the one side surface 1B are substantially parallel to each other.
A suitable number of spacers 13 are also provided between B and one side surface 1B.

A bolt 15 passes through each through hole 14 provided in the rail 11 so as to pass through the corresponding through hole 2 formed in the member 1.
By tightening the nut 16 screwed to the tip of the bolt 15, the member 1 is firmly fixed to the rail 11 with a predetermined space between the first portion 11A and the second portion 11B.

Reference numeral 17 denotes the support guide groove 12
Rail 11 so that it can be supported and guided by
It is a hanging piece attached to. At the upper end of the main body 17A, the hanging piece 17 is provided with an annular metal fitting 17B for connecting to a hook of a lifting machine (not shown).
A screw foot 17C extends integrally from the lower end of A,
A screw foot 17C penetrates the support guide groove 12 and protrudes from the back surface 11E of the rail 11. Because of the space between the rail 11 and the member 1 secured by the spacer 13, the tip of the screw foot 17 </ b> C is separated from the upper surface 1 </ b> A and one side surface 1 </ b> B of the member 1.
7 is not disturbed.

A nut 18 having a size larger than the width of the groove 12 is screwed to the screw foot 17C, and the nut 18 prevents the screw foot 17C from coming out of the support guide groove 12. Therefore, when the nut 18 is loosened, the suspension piece 17 is supported and guided by the support guide groove 12, and can freely move along the longitudinal direction. On the other hand, the hanging piece 17 can be fixed to the rail 11 at an arbitrary position along the support guide groove 12 by tightening the nut 18. As described above, since the corner portion 11D is formed in an arc shape,
The suspension piece 17 can also be smoothly moved along the support guide groove 12 at the corner portion 11D.

Next, with reference to FIG. 4, a procedure for inverting the member 1 using the metal fitting 10 when the member 1 is suspended by a hoist (not shown) by the metal fitting 10 mounted on the material 1. I will explain. In FIG. 4, reference numerals are given only to main parts necessary for the inversion procedure.

FIG. 4A shows a state in which the member 1 is lifted vertically. In this case, the hanging piece 1
7 has been moved to the second portion 11B of the rail 11, and a hanging piece 17 is fixed to the second portion 11B by a nut 18. Ring bracket 17B of hanging piece 17
For example, a rope is passed through, and the member 1 is vertically lifted by locking the rope to a hook of a lifting machine (not shown).

In order to turn the vertically lifted member 1 horizontally, the member 1 is temporarily lowered onto the ground E and temporarily placed. This is the state shown in FIG. When the member 1 is temporarily placed in this way, the hanging piece 17 is made movable along the support guide groove 12 by loosening the nut 18. At this time, the annular fitting 17B of the hanging piece 17 is still locked by the hook of the hoist via the rope.

Thereafter, the hanging piece 17 is moved from the second portion 11B to the first portion 11A while tilting the member 1 so that the member 1 is turned sideways (FIG. 4C).

With the member 1 temporarily placed sideways on the ground E in this manner, the hanging piece 17 is moved to a position corresponding to the center of gravity of the member 1, and the hanging piece 17 is tightened by the nut 18 to thereby lock the rail 11. (Fig. 4 (D)).

Then, when the member 1 is lifted by the lifting machine, the member 1 is lifted in a horizontal state (FIG. 4E). That is, the hook (not shown) and the hanging piece 1
It is possible to perform a reversing operation of changing the lifting direction of the member 1 from the vertical direction to the horizontal direction without releasing the connection state with the member 7.

As described above, an example of the embodiment of the present invention has been described, but the present invention is not limited to this embodiment, and various modifications are possible. For example, the end of the first portion 11A of the rail 11 is extended to extend the other side surface 11D of the member 1 (FIG. 2).
4), a groove 12 is extended to the third portion, and the hanging piece 17 is fixed to the third portion in the step of FIG. , The member 1 can be turned upside down.

In any case, when the member 1 is light, the direction of the member 1 can be reversed in the air without temporarily placing the member 1 on the ground E.

As described above, the use of the metal fitting 10 makes it possible to perform the reversing operation of changing the hanging posture of the member 1 without using another jig and without separately preparing a counter lift. It is economical. Further, as is apparent from the description based on FIG. 4, since the member 1 can be turned over without releasing the connection between the hook of the hoist and the hanging piece 17, attachment and detachment of the hook which makes the turning operation cumbersome. It can be done in a short time without any work. Further, since there is no work for removing the hook of the lifting machine, the reversing work of the member 1 in the air can be performed safely.

[0026]

According to the present invention, it is possible to perform a reversing operation for changing the suspension posture of a member without using another jig and without separately preparing a counter lifter, so that economy is improved. Is excellent. Further, since the reversing operation of the member can be performed without releasing the connection between the hook of the hoist and the hanging piece, the reversing operation can be performed in a short time without troublesome detachment of the hook. Further, since there is no work to remove the hook of the lifting machine, the reversing work of the member in the air can be performed safely.
