Description

[Detailed explanation of the invention] [Industrial application field] This invention is a method for installing wall panels such as PC curtain walls in high-rise buildings, when lifting the wall panels with a crane on the ground. This relates to a device for raising the device upright.

[Prior art]

Conventionally, this type of wall slate erection has been carried out using a lifting crane, or by swinging the wall slate support 1 through an input operation as shown in FIG. 2 to erect the wall slate 2. is generally known.

[Problems to be solved by this idea]

However, with the former method, it takes time to use a crane to raise up the wall slabs that have been delivered flat, and the lower end of the wall is brought into contact with the wall during the raising process, which can damage the corner of this end. .

In addition, the latter is installed on the wall plate 2 so as not to damage the edges.
By placing the support stand 1 in a horizontal state and making it possible to swing the support stand 1 by inputting an input operation, that is, to raise the wall plate upright, the support stand 1 can be freely swung on the mount 3 at its central position. need to be supported.

Therefore, when placing the wall slab 2 on it, it is troublesome to align the center of gravity so that the support base 1 can maintain a horizontal state, and if the center of gravity is not aligned, it will swing suddenly, which is dangerous. Moreover, a considerable amount of force is required to slowly swing the support base 1 on which the wall plate is placed by manual operation.

For these reasons, although the latter conventional device can prevent damage to the edge of the wall slab, the erection work is dangerous and requires a considerable amount of time.

This invention was devised in view of the above-mentioned circumstances, and its purpose is to provide a device that can raise wall slabs reliably without damaging the edges, easily, without danger, and in a short time. It is in.

[Means for solving problems]

The wall plate erection device of this invention has a movable frame on which a wall plate can be placed, one end of which is pivoted to the base frame, and the other end of which is pivoted to the tip of a fluid pressure cylinder that is pivoted to the base frame. The movable frame is installed so that it can be raised vertically with the pivot point at the center and the other end facing upwards, and a locking piece is attached to the upper surface of one end of this movable frame, and a link mechanism that is linked to the raising of the movable frame at the other end keeps the movable frame horizontal. A work scaffold is provided to maintain the movable frame, and the movable frame is configured to raise a wall plate placed on its upper surface by locking its lower end with a locking piece.

The wall slab can be easily and reliably raised without damaging the end portion by using a movable frame driven by a fluid pressure cylinder without relying on input operations.

〔Example〕

This invention will be explained below with reference to an embodiment shown in FIG.

The erecting device 6 is pivoted to the base frame 8 so as to be erected by the drive of a fluid pressure cylinder 7, and is locked at one end to attach a wall plate 9 to the upper surface 10a.
A work platform 11 is pinned to the other end of the movable frame 10 and is always kept in a horizontal state by a link mechanism 16 interlocking with the movable frame 10. It's summery.

The movable frame 10 is provided with a locking piece 10b that locks one end of the wall plate 9 at one end of the upper surface 10a, and a locking piece 10b that locks one end of the wall plate 9 at one end of the lower surface 10c. The piston rod 7a of the fluid pressure cylinder 7 is pinned to the base frame 8 at the upper end and the other end of the lower surface 10c, and is attached to the base frame 8 by being pivotally connected to the tip end of the piston rod 7a.

The movable frame 10 has one end downward and the other end upward, and the mounting wall plate 9
It is designed to erect.

The work scaffold 11 is attached to the movable frame 10 by having one end pinned to the other end of the lower surface 10c of the movable frame 10.

Further, the other end of a support bar 13, which has one end pinned to the lower part of the mounting plate 12 of the base frame 8, is pinned to the work scaffold 11 at the lower end of the mounting plate 14 protruding from the lower surface 11a. ing.

This support bar 13 is connected to the movable frame 10
Together with both mounting plates 12 and 14, a link mechanism 16, which is a parallel crank mechanism, is configured.

Note that the reference numeral 15 is a drive control unit for the fluid pressure cylinder 7.

In order to carry out the work of raising the wall slabs 9 using the erection device 6 having such a configuration, first the wall slabs 9 that have been carried in flat are placed on the movable frame 10 in the state shown by the solid line in FIG. On the upper surface 10a,
It is placed while one end is locked to the locking piece 10b.

Next, a worker (not shown) gets on the work platform 11 and drives the fluid pressure cylinder 7 to move the movable frame 1
Make 0 stand up.

Then, when the movable frame 10 is erected centering on the upper end shaft attachment part of the mounting plate 12 and the wall slab 9 is erected in the state shown by the imaginary line in FIG. 1, the worker on the work scaffold 11 Wall version 9
The other end is connected to the crane hook 15.

Thereafter, the wall slab 9 is lifted up by a crane (not shown), the movable frame 10 is returned to the state shown by the solid line, and a new wall slab 9 is placed.

By sequentially repeating these steps,
To easily and quickly erect a wall slab 9 when installing a wall slab in a high-rise building, etc.

[Effects of the invention] The movable frame on which the wall slab is placed is raised up by a hydraulic cylinder drive, so there is no need to consider balance such as center of gravity alignment when placing the wall slab, making the work of placing the wall slab dangerous. It can be done easily and in a short time without any hassle.

Also, since it is driven by a cylinder, the movable frame can be raised reliably, smoothly, and quickly.

Furthermore, since the movable frame is erected with one end where the wall slab is locked downward, the end where the wall slab is locked will not be damaged.

At the other end of the movable frame, which is the upper end when the movable frame is erected, a work scaffold that is always kept horizontal is provided.

For this reason, the work scaffold 4 of the conventional device is of a fixed type as shown in Fig. 2, and the worker 5 can climb up only after the wall slab is raised up and reaches the horizontal state shown by the broken line. Erecting operations can be performed while standing on the work scaffold.

This means that you can connect the upper end of the wall slab to the crane hook immediately after raising it.
This means that the work of lifting the wall slab can be done quickly.

The work of raising and hoisting the wall slab from the above-mentioned dowel can be done easily and in a short time.

As shown in FIG. 2, the conventional device requires a mount 3 large enough to support it without contacting the ground surface when it is in the upright state indicated by the broken line, making it large in size. However, in the present invention, the movable frame is a hydraulic cylinder. By driving it, it is possible to reduce the size without requiring such a frame.
