[Industrial applications]

 The present invention is used when hoisting a beam or a girder, and relates to a hanging tool for a beam or girder that can be hoisted quickly and safely.

[0002]

[Prior art]

 FIG. 3 is a diagram showing a conventional method for lifting a beam or a girder by a rope. When the beam (6) or girder is hoisted, the rope (7) is hung on both sides of the beam (see FIG. 3 (a)), and the rope (7) is lifted and placed at a predetermined position. It was

[0003]

[Problems to be solved by the device]

 However, when the rope (7) is applied, if the center of the beam (6) or girder is not on the lifting line of the rope (7), the beam (6) or girder will tilt [Fig. )], It was dangerous to lift it up as it was. In addition, when fixing it, it was necessary to lower it once and check the position of the rope (7) again before it could be lifted up, which was troublesome. In addition, there is a problem in that the rope hanging requires skillful techniques such as the position or the interval to which the rope (7) is hung, the way to tie the rope (7), and it cannot be done by anyone.

The present invention provides a beam / girder suspension which is used when hoisting a beam or a girder, can be hoisted quickly and safely, and can eliminate the trouble of removing it.

[0005]

[Means for Solving the Problems]

 The present invention has been made to solve the above problems, that is, in order to attach to a beam or a girder, a fixed shaft is inwardly attached to one end of a U-shaped metal fitting body in which each piece can be opened outward. It is fixed at a right angle, the tip is bent to form a locking part, and a clamp for locking the locking part with this locking part to hold the whole closed shape is provided. A plurality of wing bolts for holding down the side surface are attached, and in order to be lifted on the center of the fixed beam or girder, the fixed shaft is provided with a horizontally movable hooking tool. Further, when the metal fitting body is opened, it is preferable that it is formed into a single rod shape so that it can be easily removed.

[0006]

[Action]

 Next, a method of using the present invention will be described. First, when attaching to the beam (6), the rope (7) is passed through the rope suspension portion (32) of the hooking tool (3) in advance and tightened, and then opened outward to form a rod. First of all, the one in the above state is placed at an appropriate position on the beam (6). Generally, two products of the present invention are used and both sides of the beam (6) are lifted. Next, bend the support rod (11) side of the metal fitting body (1) against the bottom surface of the beam (6) [see FIG. 2 (a)], and bend the movable rod (12) to the side surface of the beam (6). Insert the fixed shaft (2) into the cut groove (12a) and lock the locking part (2a) and the clamp (4) at the tip of the fixed shaft (2a) to make the whole closed shape. It is formed [see FIG. 2 (b)]. Then, a plurality of butterfly bolts (5) screwed to the fixed rod (13) side are tightened to bring the side surface of the beam (6) into contact with the movable rod (12). After that, the left and right movable hooks (3) provided on the fixed shaft (2) are moved to the right and aligned with the center of the beam (6) [see FIG. 2 (c)]. At this time, after the product of the present invention is attached to both ends of the beam (6), the rope (7) is lifted and moved to the attachment position of the beam (6) and placed. Then, when the clamp (4) is unlocked from the locking part (2a), the U-shaped metal fitting body (1) that allows each piece to open outward is opened while falling downward by its own weight. It becomes a single rod, and the device of the present invention is naturally removed from the beam (6) [see Fig. 2 (d)]. After this, the locking part (2a) is moved so as not to contact the beam (6), and the device is placed at the position of the next beam (6), and the work is repeated in the same manner as above. . The butterfly bolt (5) is adjusted or checked every time the beam (6) is attached. Further, when tightening the rope (7) to the rope suspension portion (32), the rope suspension portion (32 The eyebolt (32a) attached to) is loosened and opened, and the eyebolt (32a) is threadedly engaged with the wheel, so that the eyebolt (32a) can be easily attached and detached.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. Reference numeral (1) is a U-shaped metal fitting body in which each piece can be opened outward. The metal fitting body (1) includes a support rod (11) for a square pipe that supports a beam (6) or a girder, and the support rod. There are a movable rod (12) of a square pipe axially supported at one end of (11) and a fixed rod (13) of a square pipe axially supported at the other end of the support rod (11). Further, a cut groove (12a) is formed at one end of the movable rod (12). A rubber plate may be attached to the inside of the metal fitting body (1) to prevent the beam (6) from being scratched and slipped. (2) is a fixed shaft fixed to the tip of the fixed rod (13), the tip of the fixed shaft (2) is bent upward to form a locking portion (2a), and the cut groove (12a) Can be inserted into. (3) is a hooking tool comprising a pipe material (31) which is inserted into the fixed shaft (2) and is movable left and right, and a rope suspension part (32) which is fixed to the outer center of the pipe material (31). An eyebolt (32 a) is screwed into the rope suspension portion (32) so that a part of the suspension portion (32) can be opened. Reference numeral (4) is a clamp provided outside the movable rod (12), and the clamp (4) is locked to the locking portion (2a). In order to prevent the clamp (4) from coming off, a spring (not shown) may be provided so that it can be set in a state in which the spring is urged during clamping. (5) is a plurality of wing bolts screwed to the side surface of the fixed rod (13), and it is preferable to attach a spring (5a) to the wing bolts (5) to prevent them from coming off. The butterfly bolt (5) is not limited to the side surface of the fixed rod (13) and may be screwed to the side surface of the movable rod (12) as long as the operation of the clamp (4) is not hindered. .

[Effect of device]

 By having such a configuration, the present invention has the following effects.

As described in claim 1, the U-shaped metal fitting body (1) which can be opened outward and the fixed shaft (2) surround the circumference of the beam (6) or girder, and the metal fitting body (1) is locked. Since the part (2a) and the clamp (4) are provided so as to be able to be locked, no skill is required when hanging the rope (7) as in the conventional case, anyone can do it easily and it takes a lot of time and effort. Absent. Also, when the clamped state of the clamp (4) is released, the metal fitting body (1) is opened to the outside and can be easily removed from the beam (6). Furthermore, since the hook (3) can be moved to the left and right, the deviation from the center of the beam (6) and girder can be eliminated, and there is no fear of tilting the beam (6) or girder as in the conventional case. You can withdraw. Therefore, if the present invention is used when hoisting the beam (6) or the girder, it can be hoisted quickly and safely, and there is almost no trouble to remove it.

According to a second aspect of the present invention, the metal fitting body (1) is a square pipe and each piece is formed in a U shape so that it can be opened, and a part of the rope suspension portion (32) is opened. By making it possible, it is possible to mount the beam (6) or the girder in a stable state, and it is easy to remove the rope (7).

When the metal fitting body (1) is opened as in claim 3, it becomes a single rod, so that the device of the present invention is removed from the beam (6) naturally and is bulky when carried. Instead, it is a convenient thing.
