Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a hanger used to install a U-shaped groove.

[0002]

[Prior art]

 The U-shaped groove is a U-shaped piece of concrete and is a civil engineering material that is often used to lay gutters. 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 that wire, or hold both side wall parts of the U-shaped groove with a grip tool, I used to hang the U-shaped groove with a grip tool and carry it to the installation position.

[0003]

[Problems to be solved by the device]

 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 a wire and a grip tool necessary for installing the U-shaped groove is complicated. The present invention has been made in view of this point, and an object thereof is to enable easy transportation and installation of the U-shaped groove.

[0004]

[Means for Solving the Problems]

 In order to solve the above problems, the present invention provides a horizontal member extending in the width direction of the U-shaped groove, and a side member extending in the depth direction of the U-shaped groove is fixed to the horizontal member. A slide column that sandwiches one side wall of the U-shaped groove is attached movably in the depth direction of the U-shaped groove together, and an abutting portion that abuts the side wall of the U-shaped groove is formed on the side material. The hanging part is provided on the side opposite to the side material of the slide pillar.

【Example】

 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 the horizontal member 1 as shown in the figure, the horizontal member 1 extending in the width direction of the U-shaped groove, the side member 3 extending in the depth direction of the U-shaped groove, and the horizontal member 1. 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 composed of members 1a and 1b made of square pipe steel and connecting plates 1c and 1d made of flat bar steel, and a slide column 5 can be inserted between the members 1a and 1b. A space is provided, and both are connected by connecting plates 1c 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 end portions 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 drawing, 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 FIG. 3). An abutting plate 9 is attached to the lower end of the side member 3 with bolts 11 and 11 and nuts 13 and 13. An adjusting nut (not shown) is arranged between the contact plate 9 and the side member 3, whereby the horizontal position of the contact plate 9 can be adjusted.

The slide column 5 is made of square pipe steel material, and a stop plate 15 is fixed to the upper end of the slide column 5. 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, and the slide column 5 is stopped. A contact plate 17 is attached to the lower end of the slide column 5 with 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, a pin 23 that is movable in the width direction of the U-shaped groove and a semi-cylindrical guide 25 that accommodates the pin 23 are provided. 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 by an adjusting nut 29 at a position adjacent to the slide column 5 and opposite to the side wall 3.

An extension member 31 made of a square pipe steel material 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 the extension member 31 pulled out by inserting the pin 33 into the lateral hole 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, the slide column 5 is first lifted upward, the pin 23 is inserted into the hole 5a, and the slide column 5 is kept raised. In this state, the side member 3 is applied to the outer surface of the side wall S of the U-shaped groove, and 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, the extension member 31 is pulled out and fixed by the pin 33 as shown by the chain line in FIG.

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. If necessary at this time, the positions of the contact members 9 and 17 are adjusted in advance so that the side wall S 1 of the U-shaped groove is firmly sandwiched between the side member 3 and the slide 5. After that, the hook 7 is lifted by a crane or the like. 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, while the inner surface of the side wall S is pressed by the slide column 5, so that the side wall S of the U-shaped groove is pressed. Is held between the side members 3 and the slide pillars 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 keeping it almost horizontal.

According to the above, the suspending tool can be easily attached to the U-shaped groove, and the U-shaped groove can be transported and installed with less labor. For example, regarding the installation work that conventionally required 3 to 4 artificial works, the use of the U-shaped groove suspender according to the present invention makes it possible to perform the work itself with only one artificial work.

Further, when the U-shaped groove is installed near a wall such as a folding screen, conventionally, the U-shaped groove is once lowered to a position away from the wall and then manually carried to the side of the wall. However, when 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 to a position just near the wall. It is also possible to transport by.

In the above embodiment, the hook 7 is attached at the fixed position, but the member 1a may be provided with a plurality of attachment holes so that the attachment position of the hook 7 can be adjusted according to the width of the U-shaped 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. .

 As described above, according to the present invention, it is possible to easily transport and install the U-shaped groove.
