Description

Double insulated curtain wall

The present invention provides a double insulation structure to block the cold and heat conducted through the outer wall member (double-layer glass) connection part of the vertical bar and the horizontal bar constructing the curtain wall, and It relates to a double insulation curtain wall that improves the assembly structure according to construction to increase construction workability and improves airtightness and assembly strength as an integrated structure by simplifying the configuration of the connection part.

In general, the curtain wall method is a method in which the outer wall does not support the load of the building, but only acts as a partition. In the case of high-rise buildings over 100m tall, it is much easier to attach panels made in the factory, and it is well known as a method widely used in high-rise buildings because it is excellent in appearance.

In this curtain wall method, horizontal bars and vertical bars are installed in a grid shape, and glass (double-layer glass) is installed in the grid shape to form a wall. While it has the advantage of shortening the period, it is the biggest task to maximize the insulation of the assembly part because almost the entire surface of the exterior wall is treated with a glass finishing material (double-layer glass).

In other words, if thermal insulation is not ensured in the connection part that supports the end side of the double-glazed glass and binds to the vertical and horizontal bars, the cold air and heat from the outside through the connection part are conducted to the indoor side, and it was pointed out as the most improved part.

For example, Patent Documents 1 to 3 disclose a technology for a curtain wall in which heat insulation technology is improved.

Patent Document 1 discloses an inner heat insulating member coupled to a frame having a vertical bar or horizontal bar function, an inner connecting member assembled to the inner heat insulating member, a heat insulating member coupled to one side of the inner connecting member, and coupled to the other side of the heat insulating member A curtain wall composed of an outer connecting member that comprises an outer connecting member, a finishing member coupled to the connecting member, and a glass panel constructed in an airtight state between the frame and the closing member is disclosed, but a plurality of constituent members for the construction of the glass panel As a medium, there was a disadvantage in that the insulation properties were poor due to leakage of gaps between the constituent members due to the construction work and the assembly of multiple constituent members.

Patent Document 2, by mixing an aluminum frame and a synthetic resin frame, can have a structural rigidity higher than the standard for use, and have low thermal conductivity, so that the insulation of a building can be improved, but one side of the frame connector is assembled with a slide fit in a metal frame, The second male connector is assembled on the other side of the frame connector by slide fitting, and the metal frame, the frame connector, and the second male connector are fastened by screw fastening. By combining the first and second male connectors with a fastening anchor in a state where the first male connector is pressed into the other side of the connector, the assembly work is very difficult as well as a large number of components. There is a disadvantage that insulation work is complicated because airtight work of the gap is required.

Patent Document 3 discloses an indoor frame, an outdoor frame positioned on the outdoor side, a first insulation material assembled to the indoor frame by a slide fitting method, and an outdoor frame that is in close contact with the other side of the first insulation material. A pair of second insulation materials positioned on both sides of the first insulation material in a state in which the first insulation material and the indoor frame are integrally connected by a bolt and assembled to the indoor frame and the outdoor frame by slide fitting while enclosing the edge of the double-glazed glass; As it is composed of a cover coupled to the outdoor side of the outdoor frame, it requires a large number of components, as well as a heavy glass (double-layered glass body) is assembled to the indoor frame and the outdoor frame by a slide fitting method of concave-convex fit. The disadvantage is that it is difficult and takes a lot of time to construct. That is, the second insulating material surrounding the edge of the glass installed in the grid shape formed by the horizontal bar and the vertical bar is slide-fitted in the longitudinal direction of the indoor frame. .
