This U.S. Patent Application claims priority of Republic of Korea Patent Application No. 10-2021-0077211 filed Jun. 15, 2021, the disclosure of which is incorporated herein in its entirety by specific reference thereto.
The present invention relates to a slim double-skin structure (or a slim double-outer skin structure), more specifically, a slim double-skin structure enabling to reduce a width of an air cavity layer (or a hollow layer) of a corridor-type or a compact-type double-skin “window and door”.
The double-skin windows and doors structure are widely used as a technology for saving cooling and heating energy in buildings.
The biggest feature of double-skin windows and doors, which have a structure in which two windows face indoors and outdoors respectively, is to reduce the solar heat gain coefficient (SHGC) into 0.1 to 0.2 or less by throwing out to the outside the overheat in the air cavity layer caused by solar radiation inflowing during the cooling period.
Generally, a glass with very high transmittance is selected for a glass of windows and doors applied to the exterior surface, and in the cooling period, the overheating in the air cavity layer is thrown away to block solar radiation, and in the winter season, warm preheat that is generated from the air cavity layer in the same way is introduced into the room, then the ventilation effect can be maximized.
The most common double-skin windows and doors are a corridor-type double-skin (800 mm of a hollow layer width) that can control the inflow of solar heat by installing a blind in the hollow layer, but there are limitations in that the structure is too large, complicated, and expensive.
In addition, the outer window is normally configured to be an electrically opened and closed structure, so that it is configured to be an automatically closed structure to protect a pent roof of the hollow layer when the external wind pressure is high.
Accordingly, by reducing the width of the hollow layer to within 200 to 300 mm to lighten the structure, the market for compact double-skin windows and doors with awnings or pent roofs in the hollow layer, which can be reasonably configured in terms of cost, could be grown.
However, there is a limitation that damage and the need for maintenance increase when the awning applied to the hollow layer exists in the higher floor part of a high-rise building or in the high wind pressure.
Therefore, in order to secure the structural safety of the hollow layer awning, the thickness of the awning becomes thick, and a separate rail structure for fixing it should be added. Also, it is prepared so that the awning can be electrically turned off when high wind pressure occurs.
