Description

[Detailed Description of the Invention] The present invention relates to a renovated curtain wall for a building whose exterior has lost its appearance due to aging.

Since the curtain wall construction method has been in use for a long time, the demand for its renovation has increased recently. By the way, since this is a renovation, the interior of the building will remain in use while the construction work is being carried out, so it is desirable that the construction work will be completed in a short period of time and without generating any noise. In addition, the use of double curtain walls not only contributes to improved soundproofing and heat insulation functions, but also ensures that the appearance of the new curtain wall will completely change when viewed from the outside compared to the curtain wall before the renovation. It makes it possible.

As a specific technical means to achieve this objective, we installed multiple body frames longitudinally through the front side of the existing mullion through mounting brackets at desired intervals in the vertical direction. Further, curtain wall mullions are fixed to the edges at desired intervals through the top and bottom, and horizontal bars are freely placed between the pair of left and right mullions, creating a space of your choice where glass, etc. are placed. Alternatively, a decorative panel or the like can be directly fixed to the furring. The details will be described below with reference to the drawings.

In FIGS. 1A and 1B, the existing mullion 5 is erected on the outdoor side of the existing building 2 by means of a pair of L-shaped fasteners 3 and 4. A horizontal bar 6 is fixed between the pair of left and right mullions 5, and a glass 7 is fitted in the rectangular space formed by the mullions 5 and the horizontal bars 6. The present application includes a plurality of mounting brackets 3 in the form of a pair of L shapes for installing the frame 8 on the outdoor side of the vertically passing mullion 5, that is, in the same horizontal direction in front of the mullion 5;
4 are fixed to the existing mullions 5 by means such as welding, and a longitudinal rim 8 for supporting a new curtain wall 9 is fixed to the outdoor side thereof. The above-mentioned furring edges 8 are arranged on the outdoor side of the existing mullion 5 in a plurality of stages in the vertical direction at appropriate intervals from the viewpoint of strength.

As shown in FIG. 1A, the new mullion 5a that supports the curtain wall 9 is fixed to the front side of the rim 8 by means such as welding, and between the pair of left and right mullions 5a is shown in FIG. 1B. The horizontal bars 6' are fixed at desired intervals in the vertical direction, and the rectangular space formed by the mullions 5a and the horizontal bars 6' is fitted with glass 7 and filled with a sealing material (not shown) using a conventional method. has been done.

The rectangular space in which the glass 7 of this embodiment is fitted is narrow in width and large in height, and is much smaller than the dimensions of the existing glass 7. This is achieved by reducing the spacing between the mullions 5a to create a narrow glass 7. Similarly, the vertical dimension of the glass 7 is achieved by changing the vertical spacing of the horizontal bars 6' to create a curtain wall of your choice. can be realized. In addition, in the example, the mullion 5a,
Although an H-shaped cross section is adopted as the cross section of the horizontal beam 6' and the furrow 8, the shape of the cross section is not limited.

Next, in FIGS. 2A and 2B, the different embodiments are in the case of a panel type curtain wall 9, and are the same as in FIG. 1 up to the newly installed furring 8. The upper and lower ends of the new panel 7' are directly attached to the furring 8, and the left and right ends can be attached at any position on the longitudinally extending furrow 8. Then, the gaps at the ends of the panel are filled with joints 10, making it possible to express a desired fine joint pattern.

As mentioned above, according to the present application, for example, when installing a new loose stick curtain wall, the mullions can be installed in any position on the rim regardless of the mullions on the existing curtain wall, so that the desired appearance can be achieved. is enforceable. Furthermore, when installing a new panel-type curtain wall, the upper and lower ends of the panel can be attached directly to the rim, making installation extremely simple.
