Description

Description: TECHNICAL FIELD The present invention relates to a curtain wall used in a building in which a large number of air conditioners (hereinafter, abbreviated as air conditioners) are installed in a distributed manner.

[Conventional technology]

Recently, a plurality of air conditioners are distributed and installed on each floor of a building, and a large number of air conditioners are installed throughout the building. Further, in such a building, a so-called through-the-wall having an opening for communicating the outside air and the indoor side to a curtain wall is used, and the opening communicates with a vent of an air conditioner.

On the other hand, in air conditioners, drain water is generated due to the condensation of moisture in the indoor air.In particular, during cooling operation, the indoor heat exchanger acts as an evaporator to generate a large amount of drain water. Rainwater enters through the opening. Therefore,
It is necessary to provide a drain pipe for drain water discharge in the building, and drain water outlets provided in a plurality of air conditioners are connected to the drain pipe and guided to the lower floor side of the building, and treated by appropriate means. ing. For this reason, conventionally, through holes are formed in floor slabs of each floor, and the drainage pipes are passed through these through holes.

[Problems to be solved by the invention]

In a conventional building, drainage pipes for draining air from the air conditioner are passed through through holes in the floor slabs on each floor, which makes the work of drilling through holes troublesome and time consuming for piping work. , Production of curtain walls, production of air conditioners,
These installation companies are different from each other, and the floor-standing type air conditioner is also different in the construction company of the peri-counter for accommodating the air conditioner.

The present invention solves the above-mentioned problems, and provides a curtain wall provided with a drain pipe for discharging drain water of the air conditioner easily and without delaying the construction period even in a building having a large number of air conditioners. The purpose is to do so.

[Means for solving the problem]

In the curtain wall of the present invention, a drain pipe for draining drain water of an air conditioner is arranged in a series on a plurality of floors in a vertical direction over a plurality of floors. A branch pipe connected to a drain water outlet is provided in the drain pipe.

[Action]

The present invention utilizes the fact that curtain walls are provided over a plurality of floors above and below a building, and a drain pipe for draining drain water of an air conditioner is arranged in the above-mentioned cubic portion to rectify an appropriate place. The drainage pipe can be piped over the entire floor provided with a curtain wall, for example, from the first floor to the top floor without making a through hole in the floor slab of each floor as in the related art. In addition, by providing the drain pipe with the branch pipe, the drain water outlet of the air conditioner provided on the required floor can be easily connected to the drain pipe by connecting the branch pipe via a flexible pipe. .
