DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a construction method for continuously installing a fan coil unit for air conditioning near a window (perimeter zone) of a building.

[0002]

2. Description of the Related Art The work of installing a fan coil unit (FCU) generally requires a number of steps as shown in FIG. 8, and in particular, the FCU and piping materials are placed on separate carts or containers and the like, and the work is performed on site. Must be unloaded from a trolley or container, lifted by human power and moved laterally, which requires extremely complicated work by multiple workers. The trolleys and containers were on site until they were empty, occupying wasted space even after they became empty, and were sometimes unnecessarily loaded and unloaded by temporary elevators for work, and repeated wasteful work. .

[0003] Japanese Patent Application Laid-Open No. Hei 5-187660 discloses a method in which two or more fan coil units are installed on a common base and pipes are connected to each other. A method has been proposed in which the efficiency of work is increased by using a single unit. Japanese Patent Laid-Open Publication No. Hei 6-300308, "On-floor connected fan coil unit", proposes a method for improving the work efficiency by incorporating a cold / hot water pipe and a drain pipe into a fan coil unit and connecting them with a connecting pipe.

[0004]

SUMMARY OF THE INVENTION It is an object of the present invention to eliminate the need for a truck or a container for moving a fan coil unit, to reduce unnecessary work, to prevent useless space from being generated, and to reduce the amount of work required. The purpose is to improve efficiency and reduce work costs.

[0006]

According to the construction method of the fan coil assembly of the present invention, since the casters under (1) frame, off
Ankoiru assembly to eliminate the need truck or container or the like when moving, moved by pushing wasted effort and space is reduced (2) fan coil assembly in a state where the pipe is connected by hand down from the track , It can be carried to a work site by placing it on a temporary elevator, and can be moved laterally to a predetermined position. The work cost is reduced. (3) The installation height of the fan coil unit can be adjusted by lowering the level adjustment bolt to ground.

(4) If the fan coil assembly is fixed with an anchor after the level adjustment bolt is lowered and grounded, and the caster is removed, the fan coil assembly can be reused, so that the management of the caster becomes easy and the manufacturing cost is reduced. (5) Even if the size of the fan coil unit varies depending on the location in the building, compatibility of the installation is maintained by making the positions of the pipe joints the same, and the connection work with the mating side can be performed. This makes it easier to use, and the working process can be greatly shortened in the whole building. Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

[0008]

FIG. 7 is a flowchart showing an example of a construction method according to the present invention. 1 to 3
Applies the present invention to a low floor type fan coil unit,
This shows a state where the casters are attached. The fan coil unit 10 is mounted and supported on a rectangular horizontal frame 12, and a pair of horizontal plates 14a and 14b are bolted along two opposing sides of the horizontal frame 12.

Below the horizontal plates 14a and 14b, a total of four casters 16 are bolted, two each. Further, a level adjusting bolt 18 for adjusting the height of the fan coil unit 10 extends downward from the bottom of the horizontal frame 12. A well-known cold / hot water coil is built in the fan coil unit 10,
A cold / hot water inlet hose 21, a cold / hot water outlet hose 22, a cold water inlet hose 23, and a cold water outlet hose 24 are connected.
These hoses are connected to metal pipes 26 to 29, respectively. The metal pipes 26 to 29 are supported on the vertical frame 13 by mounting means such as U bolts.

As will be described later, a drain hose 25 and a metal pipe 30 (shown by imaginary lines) for connecting the drain hose may be attached to the fan coil unit 10 as long as the size is within the limit dimensions for entering the elevator. Note that, as is well known, five water pipes may be three depending on the type of the fan coil unit.

According to the present invention, the positions of the joints (flange joints or housing joints) to which these pipes are connected to the other side are set to be the same even if the body size of the fan coil unit having the same capacity changes. Is done. That is, within the limits of size entering the temporary elevator, the state was connected to one or more hoses to the fan coil unit or in a state of connecting the hose and fittings, Fankoi
The assembly 20 is assembled and fit within predetermined limits.

Assembly of fan coil with pipes connected
The body 20 is loaded directly or packed in a truck, unloaded from the truck, pushed by hand, moved to a temporary elevator, and transported to a work site. At this time, there is no need to put it on a trolley or container because it has casters. At the site, it can be moved to a predetermined position by pushing it by hand. The connection position of the mating joint of the pipe are made to be the same position, off
The fan coil assemblies are compatible with each other, and the installation position is not mistaken. Thus, on-site piping installation work is simplified, work efficiency is increased, and work costs are reduced.

At the work site, the pipe on the side of the fan coil assembly 20 is connected to the other side of the pipe via a flange joint or a housing joint, and then the level adjusting bolt 18 is lowered to ground the fan coil unit. The installation height can be adjusted. Further, since the casters 16 are lifted off the floor by the grounding of the level adjustment bolts 18, the casters 1 are removed by removing the bolts.
6 and the caster parts constituted by the horizontal plates 14a and 14b can be removed.

FIGS. 4 to 6 show the fan coil assembly 40 in a state where the present invention is applied to a high-floor type fan coil unit and casters are removed. Similarly to the above-described example, the fan coil unit 10 is mounted and supported on a rectangular horizontal frame 12, and a level adjusting bolt 18 for adjusting the height of the fan coil unit 10 extends downward from the bottom of the horizontal frame 12. ing. The fan coil unit 10 incorporates a cold / hot water coil, and includes a cold / hot water inlet hose 41, a cold / hot water outlet hose 42,
3. The cold water outlet hose 44 and the drain hose 45 are connected. These hoses are metal pipes 46-5 respectively.
Connected to 0.

In FIGS. 4 to 6, the horizontal plate and the casters shown in the examples of FIGS. 1 to 3 have already been removed, and the height of the fan coil unit is set by lowering the level adjusting bolt 18 to ground. Adjust Furthermore, after the level adjustment bolt 18 is grounded, the long hole of the angled anchor 60 is bolted to the horizontal frame 12 and the lower end horizontal portion of the anchor 60 is fixed to the floor surface, thereby fixing the fan coil unit. The installed state is illustrated.

The casters and the horizontal plate that have been removed can be lowered by a temporary elevator, loaded on a truck, and mounted on a fan coil unit in the next step to be reused. The cost can be minimized because commercially available casters of various shapes, such as single wheel, double wheel, pin type, one touch type, magnet type, with bracket, with angle, with stopper, etc. can be used. The mounting and dismounting method can be freely selected without being limited to the bolting method.

As has been described in detail, according to the present invention, files of the present invention
According to the construction method of the coil assembly , a cart or a container is not required for moving the fan coil unit, the required staff is reduced, and unnecessary work is reduced, and unnecessary space is prevented from being generated. The technical effects are extremely remarkable, for example, the efficiency of work is improved and the cost of work is reduced.
