Description

DETAILED DESCRIPTION OF THE INVENTION (1) Field of Industrial Application The present invention relates to a material hanging jig suitable for, for example, installing an enclosing wall made of PC board close to a pillar.

(2) Prior Art Conventionally, in order to install this type of enclosing wall close to a column, the enclosing wall was suspended from another location using a lifting machine such as a crane by securing a wire to its upper end. It is moved and placed close to the pillar.

(3) Problems to be solved by the invention According to this conventional method, when the enclosing wall is lifted up and moved by a machine and reaches the vicinity of the pillars, the wires hit several companies and fall slightly in front of them. After that, the surrounding walls had to be moved close to several companies by hand or other means, resulting in a problem of poor work efficiency.

An object of the present invention is to solve these problems and provide a material hoisting jig with a simple structure.

(4) Means for solving the problem In order to achieve this object, the present invention includes a support frame to which materials can be attached, a lifting frame to which the upper end can be lifted, and a base that can be rotated to the middle part of the support frame. an L-shaped arm that is freely pivotable and rotatably pivoted to the middle part of the lifting frame at the middle curved part and has a weight attached to the tip; It is characterized by comprising a connecting arm which is pivotally connected and whose other end is pivotally connected to the lower end of the lifting frame.

(5) Operation Lift the lifting jig with a crane or the like, move it to a place where the surrounding wall is placed, touch the support frame of the hoisting jig to the side of the wall for a few minutes, and then lift the crane. When the wall is hung by turning it over, the weight provided at the end of the L-shaped arm balances the wall, and the rotation of the connecting arm at the lower end of the hanging frame causes the wall to be suspended. The wall is hung vertically.
In this vertical state, it can be lowered close to a steel column at a desired location.

(6) Example One example of the hanging jig of the present invention will be described with reference to the drawings.

(1) shows the hanging jig, (2) shows its support frame, and the support frame (2) is formed into a rectangle by shaped steel,
a) Consists of (2a) and 10-dore section steel (2b) (2c). In addition, (3) indicates a hanging frame, and the lifting frame (3)
) is a side plate (3
a) Connect (3a) at the top and middle, respectively +1 (
3b) (3C), and a connecting arm (4) is attached to the lower end of these side plates (3a) and (3a).
(4) are rotatably pivoted at one end thereof, and each of these connecting arms (4) (4) is connected at the other end to the lower end of the side portion (2a) (2a) of the support frame (2). Each was pivotally attached to the section. and a pair of L-shaped arms (
5) (5) is rotatably pivotally attached to the intermediate portions of both sides (2a) (2a) of the supporting frame (2) at its roots, and the lifting frame (3) ) are rotatably attached to both side plates (3a) and (3a), respectively, and cylindrical weights (6) are replaceably attached to the tips of the cursive arms (5) (5). In addition, weight (6)
The weight is determined by the balance between the moment on the weight (6) side with respect to the pivot point (B) of the curved part of the L-shaped arm (5) and the moment on the material side such as the surrounding wall (7) to be lifted. .

(7) indicates an enclosing wall, and the enclosing wall (7) is an outer peripheral wall formed of a PC plate having a U-shaped cross section and surrounding three sides of the steel column (A).

In addition, (8) shows a crane such as Guiderick, and this crane (8) has a swing post (8a), a rope (g b),
It consists of a hook (8C), etc.

Next, a method of using the hanging jig of this embodiment will be explained with reference to FIG. 4.

After hanging the hook (8C) of the crane (8) on the connecting rod (3b) and hoisting the lifting jig (1), the hoisting jig (1) is moved to the mounting location of the surrounding wall (7).

(Fig. 4(a)) Next, the support frame (2) of the hanging jig (1) is attached to the surrounding wall (
7), and bring the side parts (2a) (2a) and the lower end section steel (2C) into close contact with both side ends and the lower end of the surrounding wall (7), and angle the two wheels. (9)
and fix the bolts and nuts. (Fig. 4(b)) Next, when the rope (8b) of the crane (8) is rolled up, the weight of the surrounding wall (7) is suspended on the support frame (2), and the lifting frame (3) is lifted up. The L-shaped arm (5) (5) rotatably pivoted to the steel strip (3 a) (3 a) is moved counterclockwise at the same time to hold the weight (6), and the plan (6) is completed. balance with. At this time, the connecting arms (4) at the lower ends also rotate, and the surrounding wall (7) is suspended vertically.

(Fig. 4 (C)) Then, rotate the crane (8) to move the surrounding wall (7) to the desired steel column (A), and then gradually bring it close to the side of the steel column (A). When the surrounding wall (7) approaches the floor surface as it descends (Fig. 4(, d)), the steel column (
The descent is completed by bringing the surrounding wall (7) into contact with A).

Then, when the angle (9) and port nut are removed,
The weight (6) brings the support frame (2) into the state shown in Figure 4 (e).
Pull out the lower end section steel (2C) in the direction of arrow C and remove the hanging jig (1).

Thereby, even in a narrow place, the surrounding wall (7) can be installed in a form similar to that of a few walls.

Although the example shown in "-" is used for moving and mounting a surrounding wall of a column, it goes without saying that various materials can be moved and placed close to the final installation location without being limited to the surrounding wall.

(7) Effects of the Invention As described above, according to the lifting jig of the present invention, a support frame to which a material can be attached, a lifting frame to which the upper end can be lifted,
an L-shaped arm rotatably attached to the intermediate portion of the support frame, rotatably attached to the intermediate portion of the lifting frame at an intermediate curved portion, and having a weight attached to its tip; It consists of a connecting arm rotatably attached to the lower end of the support frame, and a connecting arm rotatably attached at the other end to the lower end of the hanging frame. When the wall is installed and hung, the wall and the weight are balanced and lifted in a vertical state, so it can be electrically connected and lowered near the pillar to be installed, which improves work efficiency and improves work efficiency. , has the effect of allowing work to be carried out safely.
