Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a suspending method and a suspending method which are used when a thin long plate-like object, especially a folded plate roof material used for a roof of a building is suspended by a crane or the like. It relates to the lower device.

The folded plate half material is not limited to this, but is a folded plate shape such as a mountain shape, a corrugated shape, and a roof bar shape, and has a plate thickness of 0.6 m.
Steel plates with a width of m to 1.2 mm and a width of 800 mm or less are often lined with heat insulating materials such as expanded polyethylene.

[0003]

2. Description of the Related Art This long plate-shaped pillar is roll-formed into various folded plate shapes on site to increase the size of the building and reduce the number of joints to prevent rain leakage. And 50
M long objects are made.

FIG. 6 is an example of a cross-sectional shape of a mountain-shaped plate-like object.
FIG. 7 is a cross-sectional view in which trapezoidal mountain shapes of the folded plate shape as described above are continuous in the lateral direction. This chevron-shaped plate-shaped product 1 is made by folding a trapezoid into a trapezoidal shape, in which a steel sheet 3 such as a zinc iron plate, a colored iron plate, or a vinyl chloride steel plate is lined with a heat insulating material sheet 5 such as foamed polyethylene or foamed gypsum. There is.

FIG. 7 is a state diagram when the mountain-shaped plate 1 is lifted on the building by a crane. The mountain plate 1 has a width of 8
The length is as short as 00 mm or less, but since it extends to 20 m in the longitudinal direction, it cannot be hung at one place, so it is hung as shown in the figure. A rigid H-shaped steel 7 or steel pipe that does not bend according to the length is hung on a hook 11 of a crane 9 with a cord 13 such as a wire rope, and a mountain-shaped plate 1 is further placed under the H-shaped steel 7. Along the side, cloth belts 15 are hung at several points and suspended.

[0006]

However, in order to hang the cloth belt 15, one person is lifted from the stack of the mountain-shaped plate-like objects 1 and several sleepers (square pillars) are placed on top of each other, and It creates a space on the side and hangs it through the cloth belt 15, which is very troublesome and time consuming. If the ground gets wet due to rain or the like, the cloth belt 15 becomes dirty on the ground, and this contaminates the heat insulating sheet 5 of the mountain-shaped plate 1 in particular. Since the seat 5 has to be cleaned from an aerial work vehicle or a similar table, a great number of man-hours and labor is a problem.

Further, even if the cloth belt 15 is hung up and lifted, when the wind blows, the mountain-shaped plate-like object 1 is fanned and the cloth belt 15 is displaced in the loop of the cloth belt 15 and becomes unstable, which makes the lifting difficult. May be.

[0008] Further, when hanging up on the building and lowering it, the cloth belt 15 is pulled down on the sleepers in the same manner as on the ground in order to pull it out, which also takes time unless it is solved by a few people.

Furthermore, since a material having a long rigidity such as H-section steel 7 is used, it is very heavy and the inclination of the crane cannot be greatly tilted. I had to carry it to the designated position.

Therefore, the present invention aims to solve these problems.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings. In the figure, the same or equivalent parts and members as in the conventional case are designated by the same reference numerals, and the description thereof will be omitted. 1 to 3 show a first embodiment of the present invention.

The mountain-shaped plate-shaped object suspending device is roughly composed of a rigid rod member 20, a fixed holding means 30, and a suspending means 40.

The rigid rod member 20 is made of a thick-walled steel pipe 21, and slits 23 are formed at a lower end of the steel pipe 21 and cut into a predetermined length from both ends.
The lid 25 is also detachably attached by screwing, fitting, etc. also as a reinforcement of the 23 part. Further, on the upper side of the steel pipe 21 opposite to the slit 23, a bolt 27 with a grip is screwed into a weld nut 29 welded to the steel pipe 21 and the tip thereof is
It is attached so as to project inward.

The fixed holding means 30 is provided at both ends of the rigid rod member 20, that is, both ends of the steel pipe 21, so as to be movable in the axial direction of the steel pipe 21, respectively. The fixed holding portion 31 of the fixed holding means 30 includes a relief portion 32a at the end of the mountain-shaped plate-like object 1 whose lower side portion is bent in a crank shape and a support portion 32b for supporting the mountain portion at the end portion. It has a base 32 and a sandwiching plate 33 facing the supporting portion 32b in a U-shaped cross section. This sandwich plate 33 is a base
A gripping bolt 35 with a grip, which is screwed into a weld nut 34 welded to the upper side of 32, can be attached to and detached from the support portion 32b.

At the tip of the pinch bolt 35, a base 35a fixed to the pinch plate 33 forms a spherical pair with the shaft portion 35b, and the pinch plate 33 is attached.
It is possible to rotate the grip portion 35c of the pinch bolt 35 while the base 35a does not move. A rubber is provided on the opposing surface side of the support portion 32b and the sandwiching plate 33 to prevent scratches and slip when the mountain-shaped plate 1 is sandwiched.
32c and 33a are attached by pasting or baking.

The slider 36 of the fixed holding means 30 is a steel pipe 21.
It is a steel pipe with a thickness and length that can be freely moved inside, and between the slider 36 and the base 32 as shown in FIG.
A pin 37 of the book penetrates through the slit 23 and the wall surface of the slider 36 and is welded at the position of the slider 36 and the base 32.
Therefore, the fixed holding means 30 is movable along the axial direction of the rigid rod-shaped member 20, and the fixed holding interval (for example, 300 mm to 800 mm) can be changed according to the size of the width of the chevron-shaped plate 1. .

The suspension means 40 is a steel pipe which is the rigid rod member 20.
Form a hole 41 in the flattened part by pressing the center of 21,
A carabiner 42 is formed in this hole 41. Carabiner
A portion 42a of the tube is opened, and a portion 42a of the tube 42 is biased by a spring (not shown) so as to close as shown. By this carabiner 42, it is possible to connect with the end loop of the wire rope 13.

FIGS. 4 and 5 show a second embodiment of the steel pipe.
Made of angled material 21a instead of 21 and fixed holding means 30
However, the suspension means 40 is fixed to both ends of the rigid rod-shaped member 20, and the suspension means 40 has a tongue piece 43 welded to the center thereof.
A hole 44 is formed in the shackle 45 similar to the carabiner 42.
(U-shaped open end is closed with a bolt). Further, the mountain-shaped plate-like object 1 is sandwiched only by the base 35a without the sandwiching plate 33. The clamping bolt 35 is not a disc-shaped grip but a bar-shaped one, and has a structure with sufficient force. Since the mountain-shaped plate-shaped object suspension device of this embodiment cannot be moved and adjusted in the axial direction (width direction), it is necessary to prepare the mountain-shaped plate-shaped object 1 having a size corresponding to the width type. .

[How to use] Depending on the length of the topmost mountain-shaped plate 1 in a state where many mountain-shaped plate-shaped products 1 are stacked, the mountain-shaped plate-shaped products shown in FIG. The device is arranged so that the rigid rod member 20 extends in the lateral direction of the mountain-shaped plate-shaped object 1.

As shown in FIG. 2, the fixing and holding means 30 is located at each end of the chevron-shaped plate 1 at each location, and the escape portion 32a of the base 32 is provided.
The slider 36 is moved so that the end enters and the mountain portion is placed on the support portion 32b. The slider 36 slits inside the steel pipe 21.
It is smoothly moved by a pin 37 guided by 23 and is fixed by tightening a bolt 27 at an appropriate position.

In this state, when the clamping bolts 35 are evenly tightened on each side, the clamping plate 33 clamps the mountain-shaped plate-shaped object 1. At this time, since the sandwiching plate 33 and the supporting portion 32b are provided with the rubbers 33a and 32c, respectively, the mountain-shaped plate-like object 1 is not scratched and is securely held without slipping. be able to. Further, since the sandwiching plate 33 and the supporting portion 32b are not held at one point but are held by the surface over a long range, the above-mentioned effect is further enhanced, and the sandwiching portion is orthogonal to the longitudinal direction of the mountain-shaped plate 1. There is no line in the direction.

Next, the end of the wire rope 13 is passed through the carabiner 42 passing through the hole 41 of each suspension means 40, and the other end is hung on the hook 11 of the crane 9.

When the crane 9 is operated and hoisted above the building, a fixed portion corresponding to the mountain shape of the mountain-shaped plate-like object 1 is fixed to the building, and it is lowered while adjusting to this position. When the position is determined, the wire rope 13 is loosened, the pinch bolts 35 are loosened, and the mountain plate-shaped object 1 is removed.

This mountain-shaped plate-like object suspension device is equipped with a wire rope 13
It is hoisted again by the crane 9 via the and is lowered to the ground. Repeat this many times. This operation is the same in the first and second embodiments.

[0027]

[Effect] Compared to the conventional method of hanging and hanging the cloth belt, it is not necessary to put it on the sleeper, and the operation can be performed simply from above and the number of steps can be reduced. This will increase the safety of crane operation with less manpower on the ground and on the roof. Dirt on the heat insulating sheet due to belting is eliminated, and post-cleaning is eliminated, reducing man-hours.

As compared with the cloth belt, the mountain-shaped plate-like material is not displaced, so that it can be stably held even in a stronger wind, so that the crane can be operated a little faster and is safe.

Since a heavy suspension device such as H-shaped steel is not used, the crane can be extended even in a large building, and can be considerably tilted down so that it can be lowered into a predetermined position without being lowered to the end, which is dangerous for many people. Do not lift and move the mountain plate on the beam.

From these effects, it is clear that the number of days conventionally required can be greatly shortened.
