Description

Description: TECHNICAL FIELD The present invention relates to a method for forming a curtain wall having a lateral frame with an emphasized appearance and firmly holding the left and right end portions of a face material.

(Prior Art) Conventionally, to form a horizontal frame-emphasized curtain wall, horizontal fixing is performed on a plurality of building exterior surfaces of the horizontal frame, which is a main member, with a required vertical interval, and then between the horizontal frames. A method has been adopted in which a plurality of vertical frames are vertically fixed with a required left-right interval, and then glass plates are attached to the horizontal frames and the vertical frames.

On the other hand, as a structure that emphasizes the horizontal frame, various measures have been taken in the direction of minimizing the width of the vertical frame exposed to the outdoor side.
As an example, a wide lateral frame having glass fitting grooves on both upper and lower surfaces is used, and a narrow lateral frame having no glass fitting groove is fixed between the lateral frames, and a glass is fitted in the glass fitting groove of the lateral frame. The applicant of the present invention has proposed a structure in which the upper and lower ends of the plate are fitted and a space between the left and right ends of the glass plate and the vertical frame is sealed with a sealing material (JP-A-56-5995).
4). However, in this structure, if the vertical spacing of the horizontal frame is large, it is not possible to obtain sufficient assurance in the mounting strength and watertightness of the glass vertical girder when a large negative pressure acts on the glass in strong wind, so the vertical frame Also, it is required to provide a glass fitting groove. However, when designing the glass fitting groove in the vertical frame, as long as the conventional glass mounting method of later fitting the glass into the fitting groove of the vertical frame once fixed is adopted, the glass fitting groove is overrun. It must be deep, resulting in a wide vertical frame and a loss of the desired lateral frame emphasis appearance.

(Problems to be Solved by the Invention) The present invention uses a vertical frame having a glass fitting groove to firmly support the left and right end portions of a glass isosurface material and to maintain the lateral frame-emphasized appearance. It is an object of the present invention to provide a method for forming a horizontal frame-enhanced curtain wall capable of achieving the above.

(Effects of the Invention) In the method for forming a horizontal frame-enhancing curtain wall of the first invention of the present application, a plurality of face materials are supported by upper and lower horizontal frames with a small space left and right, and then the outdoor side end of the substrate. The cubical sub-body, which is formed by overhanging the face material outdoor presser plate to the left and right, is inserted and fixed in the small space, and the face material chamber external presser plate presses the left and right end portions of the face material from the outdoor side. Since it is characterized by, it is possible to minimize the adjacent face material to the minimum necessary, and the face material outdoor presser plate of the cubical sub body is necessary to hold the side edge part of the face material from the outdoor side. The minimum width required is to ensure that the left and right edges of the face material can be firmly held, and the vertical frame is made thin to form a curtain wall that maintains the horizontal frame-emphasized appearance. It is possible to create a gap between the cubical sub-body inserted between the face materials and the face material. The gap also serves as a clearance for layer displacement due to an earthquake or the like.

In the method for forming a horizontal frame-emphasized curtain wall of the second invention of the present application, the first face material is supported by the upper and lower horizontal frames, and then the face material chamber presser plate is juxtaposed to the left and right at the outdoor end of the substrate. The cubic sub-member is arranged and fixed next to the first face material, and one side end of the first face material is pressed by the face material outdoor presser plate from one side to the outside of the face material indoor presser material. Cooperatively holding from the room, and then supporting the second face material on the upper and lower lateral frames and sliding the face material so that one end of the face material is outside the face material on the other side of the cubic sub body. It is characterized in that it is located on the indoor side of the presser plate, thereby holding one side end of the presser plate outside presser plate and the presser member indoor presser member, and the above steps are sequentially repeated. First above
In addition to obtaining the same effect as the invention, the cubic by-product does not insert the substrate into the small space between the right and left side members unlike the first invention, so that the substrate is designed without being restricted by the small space. It is also possible to do so, and it has an advantage that it is advantageous in terms of strength, a fixing structure to a cubic body, and the like.
