JPH08270205A - Lifting device of prefabricated scaffold and assembling and disassembling work thereof - Google Patents

Abstract

PURPOSE: To dispense with works at a high level as prefabricated scaffolds can be assembled and disassembled only on the ground and hence increase the safety because there is no danger such as falling of workers or dropping of scaffold materials and also operate with ease because of works free from life-lines and further, increase the working efficiency since the working space is not restricted and much area thereof is not required and dispense with cranes. CONSTITUTION: A lifting device in which a lifting girder 9 having detachable claws 20 at prefabricated scaffolds is equipped between masts 8 erected on the ground, is used. The prefabricated scaffold is hooked and hoisted by the lifting girder 9. A lower scaffold is assembled in the lower side. The same processes are repeated to assemble a multi-layer scaffold in turn. The periphery of the second layer from the lowermost one, in the multi-layer scaffold assembled by the lifting girder 9, is surrounded and the prefabricated scaffold is hooked and hoisted as the whole. Then the lowermost scaffold layer suspended afloat is disassembled and removed. The same processes are repeated thereafter to disassemble and remove the lowermost scaffold layer in turn.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for assembling and disassembling a frame scaffold used for construction and construction of civil engineering structures and equipment used therefor.

[0002]

2. Description of the Related Art As shown in FIG. 29, a frame scaffold is well known, and a building frame 1 arranged facing each other has a crosswise streak 2 at the side.
Then, in the upper part, the cloth frames 3 are connected and sequentially connected in the horizontal direction, and in the vertical direction, the building frames 1 are connected to each other by the connecting pins 4. In the figure, 5 is an arm lock.

The method of assembling and disassembling a frame scaffolding using such a building frame 1 is an example of an assembling work, as shown in FIGS.
As shown in 32, first, the first layer of the lowermost layer is assembled on the ground, and from the second layer, both ends and several spans (for example, 10 spans) are assembled. (When working, attach a safety belt to the lower scaffold.)

As shown in FIG. 31, the master rope 6 is put on the uppermost portion of the assembled second layer, and as shown in FIG. 32, the remaining two layers are assembled using the master rope 6. When the assembly of the two-layer part is completed, use the parent rope 6 that has been used until now to
As with the two-layer portion, the layer portion is assembled at both end portions and every several spans, and thereafter, the layer portions are sequentially assembled in the same manner.

On the other hand, in the case of the dismantling work, as shown in FIG. 33, the master rope 6 is attached to the floor on the uppermost floor, and the master rope 6 is used to dismantle from the top floor.

As shown in FIG. 34, the lower part of the master rope 6 is dismantled, and a new master rope 6 is installed on the floor when the frame to which the master rope 6 is attached is dismantled. Using the master rope 6, the upper master rope 6 and the scaffolds on both sides are dismantled, and thereafter, in the same manner, the upper layers are sequentially dismantled.

The above is one example of the method of assembling and disassembling the frame scaffold, and although not shown in the drawings, a master rope is erected on the floor of the uppermost frame scaffold, and the master rope is used by this pillar. There is also a method to work while tensioning a certain height.

[0008]

As described above, all of the conventional methods for assembling and disassembling frame scaffolds involve work at high places, and there is a risk of a worker falling or scaffolding materials falling. As a preventive measure, you must use a lifeline with a masterline. As a result, workability is hindered and efficiency is reduced.
