Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a movable work scaffold for use in constructing a structure. □ Full scaffolds such as frame scaffolds and single pipe scaffolds are generally used as scaffolds for construction of conventional structures. However, the structure... If the height is high, or if the cross section changes, such as the egg-shaped tank shown in FIG. 12, the framework scaffold may not be able to handle the situation. □ ・For this reason, movable scaffolding has been proposed in which rails are placed along the structure and the scaffold moves on the rails, but this has the drawback of increasing costs.

The present invention was proposed to solve these problems, and includes a pair of upper and lower scaffolding support outer pipes having fixing legs that can be attached and detached from anchors anchored to an existing structure;
An inner nano-ive is slidably penetrated across each of the outer pipes, and an inner nano-ive is disposed at the bottom of the inner nano-like pipe, and is detachable from the anchor and movable relative to the inner pipe in a direction perpendicular to the inner pipe. This invention relates to a movable work scaffold characterized by having fixed legs at the lower end.

Since the present invention is configured as described above, when the work scaffold is to be moved upward during the construction of a structure with an arbitrary cross section, it is anchored to the fixed leg of the soil outer pipe and the existing structure. Anchor. After releasing the fixation with the inner pipe and sliding the upper/outer pipe along the inner pipe and aligning it to a predetermined position, the lower end fixing leg and the lower end of the inner pipe are moved relative to each other. , the anchor of the upper outer pipe is brought into contact with and fixed to the anchor of the upper structure by swinging the inner pipe assembly, and then the lower outer pipe is raised to a predetermined position relative to the inner pipe in the same manner, and fixing the fixing leg of the lower outer pipe to the anchor of the structure, then releasing the fixation between the lower end fixing leg and the anchor of the structure, and moving the inner pipe along the upper and lower outer pipes to a predetermined position a; 1J The lower fixed leg is moved in the right angle direction of the inner ξ-ib and fixed to the anchor of the structure.Then, the same operation is repeated to move the scaffold upward. The scaffold can also be lowered by performing the reverse operation.

As described above, according to the present invention, the scaffold can be easily attached and detached from the existing structural part, the scaffold can be easily moved, and the scaffold can be directly attached to the anchor anchored to the structural part. The mounting device is easy and economical.

In addition, since the three scaffold support members of the upper and lower outer pipes and the lower end outer pipe can be raised, lowered and fixed independently, each scaffold can be moved to a desired location as needed within the range in which the outer pipe can move along the inner pipe. The present invention has many advantages, such as being able to be used by fixing it to a scaffold, thereby widening the scope of use of the scaffold.

The illustrated embodiment in which the present invention is applied to construction of an egg-shaped tank (A) will be described below.

(1) is the inner pipe, and the upper and lower outer pipes (
2) (2') is slidably fitted, and each of the outer sleeves (2) (2') is fitted with a fixed leg (31 (3')).
are pivotally attached via pins (4) (4'), and the fixed legs (3) (3) are attached to the existing structural part (11 (III) of the tank (A) (anchor bolt (5) at position 111).
It is designed to be removably fixed to an anchor plate (6) anchored via the anchor plate (6).

(') is the lower end fixed leg, and the pin (7) is attached to the anchor plate (6).
), and the guide tube (8) into which the fixed leg (3'') is slidably inserted is fitted into the inner pipe (1), and the guide tube (8) is fitted into the inner pipe (1). ) and fixed legs (3
A screw rod (9) is screwed into each flange with the end of the "), and by rotating the screw rod (9), the fixed leg (3") is configured to move in a direction perpendicular to the inner nano-ib (1). has been done. (See FIGS. 7, 8, and 9) Each of the pipes (1), (2), and (2') is constructed as a square pipe.

Scaffolding material 0 is connected to the lower ends of each of the outer pipes (2) (2') and the inner groove (1) via pins, and the scaffolding material a1 and the outer pipe (2) (2'') are connected to each other via pins.
, and the inner pipe (1) are connected to each other via pins, respectively, and a turn-node ξ-tske type telescoping member all is connected, and by the telescoping operation of the telescoping member αB, regardless of the movement position of the scaffolding material α, The scaffolding material is used to hold the scaffold horizontally.

In the figure (I) is the handrail made of scaffolding material a1, (I3) is its stay.

As shown in Figure 3, the existing structure (Il(ID[[D
When trying to raise the scaffold with the lower end fixed legs (3") and fixed legs (3') fixed to each anchor plate (6), respectively, lower outer slide (2') The cable (1ω) of a small winch (14) mounted on the structure (
It spans over a pulley αQ attached to the anchor plate (6) of the product), and its tip is connected to the suspension ring αη of the upper outer pipe (2).

Next, the fixation between the fixed leg (3) and the anchor plate (6) in the structure (nD) is released, and the upper outer pipe (2) is raised along the inner ξ pipe (1) via the winch 04. (See Figure 4) Next, the screw rod (9) is fully rotated and the inner ibe (1) is moved to the first position.
Swing in the direction of the arrow X in the figure, bring the fixed B'1l (3)' into contact with the structure (MO anchor plate (6)), and fix it to the same anchor plate (6). Then, attach the fixed leg (3') Structural part (
Release the stator with the anchor plate (6) of n), and attach the winch IO cable to the hanging ring (17
') and raised along the outer pipe (2') T-innano-ib (1) by operating the winch αa,
The fixed leg (3') is placed opposite the anchor plate (6) of the structure (2). (See Figure 5) Next, rotate the screw rod (9) to rotate the inner pipe (1) in the Y direction in Figure 1, and attach the fixed leg (3') to the structural part (
Fix it to the anchor plate (6) of 2) and lower end fixing leg ('f).
Release the fixation from the anchor plate (6) of the structural part (1), and tie the two-inch Q4 cable (I → to the suspension ring (17") K provided at the bottom of the inner ξ-ib (1)). , by operating the winch (14), pull up the inner pipe (1) along the upper and lower outer pipes (2) (2') (see Figure 6).
Identify the fixing leg (3") to the anchor plate (6) of the structure (II).

Thereafter, the same operations as described above are repeated to sequentially move the scaffolding device upward to perform the required construction.

In place of the winch, each of the pipe lifting and lowering drive devices may use a hydraulic cylinder α as shown in FIG. 1θ and a screw device (l!J) as shown in FIG. 11.

Since the illustrated embodiment is configured as described above, it is easy to attach and detach the scaffolding device to an existing structure, it is easy to move the scaffolding, and the scaffolding device can be quickly adjusted in response to changes in the shape of the structure. The scaffolding device can also be installed on fixed legs (
Since it can be directly attached to the anchor plate (6) of the existing structure via the 31 (3') (3">1
Since the three scaffolding members supported by the 3") are raised, lowered and fixed independently, the outer pipes (2) (2') can move along the inner force and the ξ (1). If necessary, each scaffold can be used by fixing it at a desired location as shown in FIGS. 4 and 5.

Although the present invention has been described above with reference to embodiments, the present invention is, of course, not limited to such embodiments, and can be modified in various ways without departing from the spirit of the present invention. .
