BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hanger used to install a U-shaped groove.

[0002]

2. Description of the Related Art A U-shaped groove is a U-shaped piece of concrete and is a civil engineering material often used for laying gutters and the like. When carrying this U-shaped groove to the installation location, for example, tie the U-shaped groove with a wire and suspend the U-shaped groove with the wire, or carry both side wall parts of the U-shaped groove with a grip tool, I used to hang a U-shaped groove and transport it to the installation position.

[0003]

Since the conventional method is as described above, it requires a considerable amount of labor, and the work of attaching and detaching tools such as wires and grip tools necessary for installing the U-shaped groove is not required. It was complicated. The present invention has been made in view of this point, and an object thereof is to make it possible to easily carry and install a U-shaped groove.

[0004]

In order to solve the above problems, in the present invention, a horizontal member extending in the width direction of the U-shaped groove is provided, and a horizontal member extending in the depth direction of the U-shaped groove is provided on the horizontal member. A slide column is fixedly attached to the horizontal member and sandwiches one side wall of the U-shaped groove together with the side member so as to be movable in the depth direction of the U-shaped groove. Further, the horizontal member is provided with a hanging portion on the side opposite to the side member of the slide pillar.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of the present invention will be described with reference to FIG.
The U-shaped groove suspender according to the present invention is attached to a horizontal member 1 extending in the width direction of the U-shaped groove, a side member 3 extending in the depth direction of the U-shaped groove, and a horizontal member 1, as shown in the figure. It is composed of a slide pillar 5. Further, the horizontal member 1 is provided with a hook 7 which is a suspending portion for suspending the U-shaped groove suspender.

The horizontal member 1 is a member 1 made of square pipe steel.
a, 1b and connection plates 1c, 1 made of flat bar steel
and a space for inserting the slide pillar 5 is provided between the member 1a and the member 1b.
They are connected by c and 1d. For this connection, for example, welding or bolting is used, but other methods may be used.

Side members 3 are fixed (welded, bolted, etc.) to the ends of the connection plates 1c, 1d. The side member 3 is formed by processing, for example, a flat bar steel material, but the side member 3 may be formed integrally with the horizontal member 1. As shown in the figure, the side member 3 is bent in an inverted V shape, and the bent portion serves as the contact portion 3a. The outer surface of the side wall S of the U-shaped groove contacts the contact portion 3a. (See Figure 3). Side material 3
An abutment plate 9 is provided at the lower end of the bolts 11 and 11 and the nut 1.
It is attached by 3,13. An adjusting nut (not shown) is arranged between the contact plate 9 and the side member 3, so that the horizontal position of the contact plate 9 can be adjusted.

The slide column 5 is made of square pipe steel, and a stop plate 15 is fixed to the upper end thereof. The slide column 5 tries to drop downward due to its own weight, but the stop plate 15 is locked by the connection plates 1c and 1d to stop the slide column 5. A contact plate 17 is attached to the lower end of the slide column 5 by bolts 19 and 19 and nuts 21 and 21. An adjusting nut (not shown) is arranged between the contact plate 17 and the slide column 5, so that the horizontal position of the contact plate 17 can be adjusted. A hole 5a for stopping the slide pillar 5 at a raised position is formed in the middle of the slide pillar 5.

On the member 1b, there are provided a pin 23 movable in the width direction of the U-shaped groove and a semi-cylindrical guide 25 for guiding the pin 23. A handle plate 27 is fixed to one end of the pin 23, and the other end of the pin 23 can be inserted into the hole 5a. The hook 7 is fixed to a position next to the slide column 5 and on the side opposite to the side wall 3 by an adjusting nut 29.

An extension member 31 made of square pipe steel is incorporated at the tip of the member 1a, and the extension member 31 is movable in the member 1a in the width direction of the U-shaped groove. A lateral hole is formed in each of the member 1a and the extension member 31, and a pin 33 is inserted into the lateral hole and the extended member 31 pulled out can be fixed at a desired length. A reinforcing plate 35 for reinforcing the slide column 5 is attached to the other end of the member 1a. The reinforcing plate 35 is made of, for example, a flat bar steel material and is fixed to the bottom surface of the member 1a.

Next, a method of using this U-shaped groove suspender will be described. As shown in FIG. 2, first, the slide column 5 is lifted upward, the pin 23 is inserted into the hole 5a, and the slide column 5 is kept raised. U in that state
The horizontal member 1 is placed on both side walls of the U-shaped groove as shown in FIG. When the length of the horizontal member 1 is insufficient, as shown by the chain line in FIG.
1 is pulled out and fixed with the pin 33.

Next, as shown in FIG. 3, the pin 23 is removed and the slide column 5 is naturally dropped downward until it abuts on the inner side surface (which is a gently inclined surface) of the side wall S of the U-shaped groove. At this time, if necessary, the positions of the contact members 9 and 17 are adjusted in advance so that the side wall S of the U-shaped groove is firmly sandwiched between the side member 3 and the slide 5. Then hook 7
Is lifted by a crane. When the side member 3 is lifted, the contact portion 3a contacts the outer surface of the side wall S of the U-shaped groove,
Since the inner surface of the side wall S is pressed by the slide pillar 5, the side wall S of the U-shaped groove is held by the side member 3 and the slide pillar 5 and lifted. At this time, the attachment position of the hook 7 is preferably near the position of the combined center of gravity of the hanger and the U-shaped groove. Then, the U-shaped groove will not tilt and can be lifted while maintaining a substantially horizontal position.

With the above arrangement, the lifting tool can be easily attached to the U-shaped groove, and the U-shaped groove can be transported and installed with a small amount of labor. For example, conventional 3-4
With respect to the installation work which was artificial, the use of the U-shaped groove suspender according to the present invention made it possible to carry out the work itself with only one artificial work.

When installing the U-shaped groove near a wall such as a folding screen, conventionally, the U-shaped groove is temporarily lowered to a position away from the wall,
After that, I manually carried it near the wall. However, if the lifting device of the present invention is used, the lifting device only supports one side wall of the U-shaped groove, and no tool is attached to the other side wall, so that the U-shaped groove can be extended right up to the wall. It is also possible to transport by.

In the above embodiment, the hook 7 is mounted at the fixed position, but a plurality of mounting holes are formed in the member 1a so that the U
You may make it possible to adjust the attachment position of the hook 7 according to the width of a character groove. Further, in the above example, the contact members 9 and 17 are adapted to cope with the change in the thickness of the side wall of the U-shaped groove, but the slide column 5 itself may be movable in the width direction of the U-shaped groove.

[0016]

As described above, according to the present invention,
This has the effect of simplifying the transportation and installation of the U-shaped groove.
