Description

  The present invention relates to an improvement of an outer wall surface of a building and a curtain wall constituting the outer wall surface. Specifically, the present invention realizes a structure that maintains the continuity of the design of the outer wall surface by eliminating the presence of joints between adjacent curtain walls in terms of appearance.

  When building a steel structure such as a building, after assembling the steel frame (frame), a plurality of curtain walls made in advance at the factory are attached to the outside of the steel frame to adjust the appearance. Various types of such curtain wall structures have been conventionally known, for example, as described in Patent Documents 1 to 5. In addition, with respect to the design of the outer wall surface of a building constituted by such a curtain wall, the requirements of the architect are diversified.

  For example, FIG. 14 shows an outer wall surface of a building constituted by a curtain wall described in Patent Document 3. Two long rectangular stone panels 1 and 1 that are long in the vertical direction are arranged in two rows in the horizontal direction, and are further arranged in the vertical direction to form first portions 2 and 2 that look like columns that are continuous in the vertical direction. It is considered that the second portions 4 and 4 including the glass windows 3 and 3 are formed between the matching first portions 2 and 2. The outer wall surface in which the first portions 2 and 2 and the second portions 4 and 4 are alternately arranged in the horizontal direction has first to third types of curtains each having a height dimension of one floor. The walls 5 to 7 are configured by combining them in order in the vertical direction. According to such a structure as shown in FIG. 14, the design of the outer wall surface of the building can be made as if the stone pillars are provided based on the presence of the stone panels 1 and 1.

  However, in the case of a conventionally known structure including the structure shown in FIG. 14 and the structure described in the above-mentioned other patent documents, between adjacent curtain walls among the outer wall surfaces of the building. A line different from the other parts appears at the joint. And this line becomes the restriction | limiting on the design design of the outer wall surface of the building comprised with a curtain wall. For example, when a concave / convex design continuous portion is provided on the outer surface of the curtain wall, the concave portion and the convex portion are regularly repeated in the direction in which the curtain walls are connected to each other, the presence of a line different from the other portions causes the seam. In the portion, the repetition of the concave portion and the convex portion becomes irregular. When such an irregular part occurs, the uniformity of the external appearance of the outer wall surface of the building is impaired (it becomes difficult to meet the requirements of the building owner).
