Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a grid-like curtain wall framework in which a plurality of horizontal bars are connected between a plurality of vertically arranged mullions with required horizontal intervals. It relates to a curtain wall fitted with panels such as glass or shoji.

Conventionally, for this type of curtain wall, mullions with grooves are used for the cross-sections of the horizontal cross-pieces on both the left and right sides of the outdoor side, and narrow inner and outer widths are used in the grooves of the mullions. A curtain wall frame is formed by connecting the ends of the horizontal bars into mullions with brackets, and fitting panels, etc. into each frame of the frame, and attaching the horizontal bars and the like to the indoor side of the horizontal bars. A structure in which a separate chest plate is attached to a mullion is known. In this conventional curtain wall, the horizontal bars and the breast plate are separate pieces, because the ends of the horizontal bars are swallowed into the receiving grooves of the mullions, so that the mullions can receive the displacement of the horizontal bars in the inward and outward directions due to wind pressure, etc. However, in order to do this, it was necessary to make the inner and outer widths of the horizontal crosspiece narrow enough to allow the mullion bridge to be inserted into the groove.Although the horizontal crosspiece is a strength member of the curtain wall frame, the chest plate is simply a This was due to the fixed idea that it was nothing more than a decorative board. However, in such a configuration, in order to obtain the required strength for the frame, it is necessary to design the horizontal beam to have considerably high strength in cross-sectional structure and wall thickness, and in addition to the extra members and man-hours required to attach the chest plate, There were drawbacks such as installation errors in the horizontal spacing of the mullions, adjustment dimensions for the connection with the frame, and thermal expansion temperature measurement of the chest plate, which required finishing of the relief gap provided between the end face of the comb plate and the mullion.

The first invention of the present application can exhibit sufficient strength as a strength member of a curtain wall frame without designing the horizontal beam to be highly strong, and also eliminates the need for extra members and man-hours for attaching the chest plate as in the past. The purpose of the curtain wall is to provide a curtain wall that can omit the following.The feature is that the mullion has a mounting part for panels, etc. formed at the outdoor end of the mullion main body that extends in the inward and outward directions in the cross section. , the horizontal crosspiece consists of a main body having a panel, etc. mounting part at a position corresponding to the panel, etc. mounting part of the mullion, and a chest plate part that is integral with the main body and extends almost to the indoor end of the mullion board, The horizontal beam is connected to the mullion with a bracket, and the bracket is configured to receive displacement of the horizontal beam in the inward and outward directions.

The above-mentioned panel attachment part is used as a general term to refer to the fitting groove and tight contact part of the window panel, waist panel, opening/closing window shoji.

The second invention of the present application is another curtain wall that can achieve the same object as the seventh invention, and its feature is that the displacement of the horizontal crosspieces in the inward and outward directions is controlled by the lateral residuals at the outside ends of the mullion. The reason is that the students were made to take it at the club.

The third invention of the present application aims to provide a curtain wall that can omit the finishing treatment of the relief gap between the breast plate and the mullions, which was conventionally done, and its characteristics are as follows: It is located where the gap is covered by a cover attached to the side of the mullion.
