Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for installing a floor-standing fan coil unit, which mainly discharges hot air and cold air from the lower part of a window of a building to cool and heat the perimeter portion.

[0002]

2. Description of the Related Art When constructing a building, a deck plate is lifted from a construction yard on the ground in the general construction method and a precast concrete floor board is lifted in the precast concrete construction method to a predetermined position on a predetermined floor by a lifting machine. Form the floor of each floor. In the conventional floor-standing fan coil unit installation method, after the floor of the floor on which the fan coil unit is installed is formed, the fan coil unit and peripheral devices are installed on a predetermined floor by a lifting lift or temporary elevator installed in the building. In addition, the fan coil unit and its peripheral equipment are installed to a predetermined position by transporting from the lifting position to the installation position on the outer periphery of the building.

[0003]

By the way, the number of fan coil units and its peripheral equipment installed in a building is very large, and it is not possible to use a lifting lift or a temporary elevator to lift the fan coil units as in the conventional case. Many workers are required for loading and unloading the fan coil unit and its peripheral equipment and transporting it from the place where it was dropped to the installation site on the outer periphery of the building. In addition, since a large amount of fan coil units and peripheral equipment must be lifted, the lifting lift, temporary elevator, etc. will be occupied for a long time, and other materials cannot be lifted during that time, and other construction work will be impossible. I can't do it. Furthermore, if a lifting lift or a temporary elevator is installed in the building, it is necessary to remove the lift and elevator, and to close the floors of these installation locations, which slows down the construction work. Therefore, it may be possible to directly lift the above fan coil unit and peripheral equipment to the installation location by using an outdoor hoist such as a tower crane. In this case, although floor covering work at the installation location of the tower crane will be eliminated, the fan coil unit and the surrounding area will be eliminated. Since the equipment is installed on the outer periphery of the building, it cannot be directly lifted to all the installation locations, and the same inconvenience as that of lifting by the above-mentioned lift or elevator occurs.

In view of the above points, the present invention provides an installation method which allows a floor-standing fan coil unit and peripheral equipment to be lifted to a predetermined position on a predetermined floor without lifting by a lifting lift or a temporary elevator. Its purpose is to provide.

[0005]

Means for Solving the Problems In order to achieve the above object, the present invention is for construction of a building in which floor material is hoisted from a construction yard on the ground by a hoist and attached to a predetermined position on each floor of the building. In the construction yard, the floor-standing fan coil unit is temporarily suspended on the bottom surface of the floor material in the construction yard, and the floor material is lifted by a lifting machine in this state. The fan coil unit was attached to a predetermined position on a predetermined floor, and the fan coil unit was temporarily suspended in accordance with the progress of the construction, and the fan coil unit was installed at a predetermined installation place. In addition to the fan coil unit, peripheral devices such as a connecting pipe and a fan coil cover are temporarily hung on the lower surface of the floor material as needed. still,
The floor material means a deck plate in a general construction method such as a steel-framed reinforced concrete structure and a precast concrete floor board in a precast concrete construction method.

[0006]

[Function] By lifting the floor material to a predetermined position on a predetermined floor with a lifting machine, the fan coil unit and further peripheral equipment are also lifted together with the floor material, and the floor is formed by the floor material, and then the floor immediately above it is formed. By simply pulling down the fan coil unit or the like temporarily suspended on the floor material, the fan coil unit or the like can be installed easily and quickly.
