DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of erection of a suspended scaffold for movable ceiling work when constructing a large space structure.

[0002]

2. Description of the Related Art Conventionally, when constructing a large space structure ,
Attach the hanger rail to the roof truss beam and use this hanger
-Engage the slider with the rail, and pivotally attach to the hanging rod of the slider.
Work chains by the angle adjustment chains provided at both ends of the support rod.
Mobile suspended scaffolding device that supports
See Japanese Unexamined Patent Publication No. 63-30065) and a long floor
A pair of gondola with support frames suspended from beams on the left and right sides of the board
And a work bridge with trolleys at both ends of a long floorboard
Nari, tow on the rails of the gondola with the bogie of the work bridge
Move the work bridge back and forth, and use a narrow work bridge to cover a wide area.
(Japanese Patent Application Laid-Open No. 53-723)
No. 21) is known, but the steel frame construction, the main fastening scaffold and the ceiling work scaffold are separately assembled.
What's is the only known, it is also the case hanging scaffold erection hung a large number of wire from the steel frame of the roof
Was only known .

[0003]

In the above-mentioned conventional scaffold erection method, a scaffold for steel frame construction and a scaffold for ceiling work are used.
Ceilings are required if there is a steel scaffolding
It is difficult to install work scaffolds, and during construction and dismantling of ceiling work scaffolds, the work inside the lower part cannot be performed, and unless ceiling finishing work is completed, the lower structure cannot be started and assembly cannot be performed. , Disadvantageous in that the dismantling is troublesome and the construction period cannot be shortened
There was Tsu.

[0004] This invention is to solve these drawbacks, it is an object to provide a construction method of a scaffold hanging can Ru transfer Doshiki ceiling work shortened work period required for the construction of large space structures.

[0005]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a movable steel-frame building foot provided on the ground.
After the steel erection work is completed in the working floor of the place, the work floor and support to tell a hanging rail from the steel frame of the roof,
Dismantled mobile steel erection scaffold and removed its support columns
Later, the work floor is suspended at a position where ceiling work is possible.
And it is intended to take measures of large space structures hanging scaffold erection method for mobile ceiling work of a scaffold hanging mobile ceiling work the working floor instead Sheng the hanging rail.

[0006]

An embodiment of the present invention will be described with reference to the drawings. In FIG. 3, a working section 4 provided with a work floor 4 of a movable steel-frame building scaffold 3 at a lower end of a supporting column 5 is mounted on a running rail 2 laid on a ground 1 to construct a large space structure. (See FIG. 4) The movable steel scaffold 3 with the wheels 7 mounted thereon
To be able to move.

After the steel frame of the roof 8 of the large space structure is constructed on the work floor 4 of the movable steel frame construction scaffold 3 and the steel frames are fully tightened, the work floor 4 as shown in FIGS. A running wheel 10 is attached to both end portions 9 of the
After the work floor 4 of the movable steel-frame construction scaffold 3 is supported by the suspension rail 13 by engaging with a suspension rail 13 suspended by wires 12 from 1, the support columns 5 of the movable steel-frame construction scaffold 3
Are sequentially disassembled from below, the support pillar 5 is removed, and the wire 12 is moved to a position 14 at a height at which the ceiling work can be performed by using a winch (not shown) as shown by a chain line in FIG. The work floor 4 is changed to a movable ceiling work scaffold 15 by being suspended.

The ceiling finishing work is performed by moving the hanging scaffold 15 for movable ceiling work from one end 16 of the hanging rail 13 to the other end (see FIG. 5), and the hanging rail 13 and the wire 12 are sequentially moved from the end of the finishing work. The removal work of the useless hole generated around the wire 12 can be removed without erection of the work passage.
5 and the work floor 4 can be removed from the rear end by sequentially removing all scaffolds. In addition, since the suspended scaffolding 15 for ceiling work is movable after dismantling the scaffold 3 for steel frame construction, it is possible to perform up and down work of a lower indoor structure and an upper structure such as ceiling finishing in parallel. The dismantling can be performed without much trouble.

[0009]

[Effect of the Invention] The present invention may not be bridged separately over the entire plane of the structure of the scaffold and ceiling work platform for steel construction side, also necessary scaffolding because the scaffold is mobile location A suspended scaffold for ceiling work by moving to
And it is possible to perform the indoor work of the lower even during the demolition, also assembled because obtain Morikawa the work floor of the scaffolding for mobile steel Ken how to movable ceiling work for suspended scaffolds, takes the hassle to dismantling and Sakarigae not may be shortened the construction period.
