Description

Ceiling structure construction method and construction device {Ceiling structure construction method and construction device}

The present invention relates to a ceiling structure construction method and construction apparatus, and more particularly, to install ceiling structures such as wiring ducts, air conditioning ducts, lighting installation rails, etc. and ceiling structures such as textiles that are installed on the ceiling. After moving the existing lift units to one place and arranging them, the ceiling structure is first assembled using the aligned lift units, and the assembled ceiling structure having a heavy weight is lifted with the main lifting device and installed safely on the ceiling. And it relates to a ceiling structure construction method and construction device that can be provided with safety.

In general, the work of installing various wiring ducts, air conditioning ducts, lighting installation rails, etc., and ceiling finishing materials such as textiles on the ceiling of a building is performed at a height using lift equipment (a high place work device).

It was a method of assembling a ceiling finishing material of a certain area after constructing various wiring ducts, air conditioning ducts, lighting installation rails, etc. However, in this method, various installation work must be performed while looking at the ceiling, so it is very difficult, there is a high risk of injury, and the work speed is inevitably slow.

A conventional high-place work device is a device that configures a work table on which a worker or work product can be placed, and enables work at various heights by raising or lowering the work table through length adjusting means such as X-lift and telescoping. am.

These high-place work devices are usefully used in modern society where buildings are becoming high-rise, but many accidents as follows occur because they have to work at high locations.

First, there is a problem that a worker may fall while working from a high position and be seriously injured. This is not only due to a defect in the device, but also because the worker's support position is higher than the work platform, so they do not receive fall prevention protection from the legally permitted handrail (H = 110cm).

Second, there is a problem of having a narrowing accident. This is because the worker is trapped between an obstacle attached to the roof or ceiling slab and the handrail of the worktable while the worktable is being raised, or when passing through an opening while driving, the height of the opening and the work handrail are not sufficient, causing the worker to reach the opening and the handrail. It can get stuck in between.

Finally, there is a problem that the work table is overturned due to damage to the length adjusting means for supporting the work table or a defect in the body due to the above problems.

The above problem is a problem caused by using the high-place work device, but in practice, the operator rides the high-place work device and moves close to the ceiling to perform the installation work near the ceiling, so it is more difficult and difficult than when assembling work on the ground. Do the work.

Therefore, when using a conventional high-place work device, it is difficult to possess and provide materials such as wiring ducts, air conditioning ducts, lighting installation rails, etc. to be installed on the ceiling, and materials such as ceiling finishing materials such as textiles. There is a problem, and moreover, due to the problem that the weight and size of the structure are limited when installing the ceiling structure after partially assembling the ceiling structure on the ground using a conventional high-place work device, this work also requires time for installation of the ceiling structure. There is a problem that takes a lot.
