When it is relatively heavy, the leg part and the expansion support are formed into the frames of L-shaped fork lift 15, and the journal part is formed into the fork part of the fork lift 15.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for mounting a transverse member such as a beam steel frame, a beam precast member, a beam formwork or the like.

[0002]

2. Description of the Related Art In a construction work, a horizontal member such as a beam steel frame, a beam precast member or a beam form is usually hung by a crane to be transported and mounted between columns.

[0003]

However, in this case, the cross members are continuously hung by the crane until their mounting positions are correctly set. In addition, even if the horizontal members that have been set once are to be corrected, the crane must be re-suspended again, which significantly reduces the operating rate of the crane.

An object of the present invention is to eliminate the disadvantages of the above-mentioned conventional example, to improve the operating rate of the crane drastically, and to provide a device for attaching a horizontal member which can simplify fine adjustment work. is there.

[0005]

In order to achieve the above-mentioned object, the present invention supports a plurality of units as a pair and supports the lower surface of a transverse member such as a beam steel frame, a beam precast member or a beam formwork with a space. As a thing, it is composed of a leg portion for preventing tilting, a telescopic column that stands up from this leg portion, and a support portion that can rotate horizontally or move vertically and horizontally at the upper end of the telescopic column, and
The tilt-preventing leg is a foldable tripod, the telescopic support is a shaft that vertically movably penetrates the shaft mounting base at the upper end of the tripod, and the support is a turntable provided at the upper end of the shaft, or , The tilt-prevention leg and the telescopic support are formed as an L-shaped forklift stand,
The gist of the vertically and horizontally movable supporting portion is that the fork portion of the forklift is provided at the upper end of the frame so as to be movable in both the X-axis and Y-axis directions.

[0006]

According to the present invention as set forth in claim 1, the horizontal member which can be continuously hung by the crane is supported at the lower surface thereof by the supporting portion so as to be held in a horizontal state even when the crane is removed, and then the prop is expanded and contracted. As a result, by rotating the support part in the Z-axis direction in the horizontal direction or moving it in the vertical and horizontal directions, it becomes possible to adjust the position in both the X-axis and the Y-axis directions, which allows three-dimensional fine adjustment and setting at a predetermined position.

According to the second aspect of the present invention, in addition to the above-mentioned action, the present invention is suitable for the case where the horizontal member is relatively light, and the leg portion for tilting prevention is a foldable tripod. Like the three legs, it can be made compact when folded, transported and stored.

According to the third aspect of the present invention, in addition to the above-mentioned action, it is suitable for a case where the horizontal member is relatively heavy, and a stable bearing can be obtained by using it like a forklift, and it can be transported and stored. Sometimes it is itself movable.
