  The present invention relates to an outer wall structure in which an outer wall panel is fixed in the form of a curtain wall to a structural frame composed of column beams of a building.

  Patent Document 1 discloses an outer wall structure in which an outer wall panel is disposed inside a structural frame made of column beams, and the frame of the outer wall panel is fixed to the column beams.

Japanese Patent Laid-Open No. 10-072886

  However, in the outer wall structure of Patent Document 1 described above, when the casing is deformed between layers, a force is applied to the outer wall panel, and the outer wall panel may be damaged depending on circumstances. Moreover, since the panel height is limited, there are many restrictions on the plan.

  In view of the above circumstances, the present invention eliminates the above-described drawbacks by positioning the outer wall panel on the outdoor side of the structural frame of the building, and can easily adjust the height of the adjacent outer wall panel. It is an issue to provide.

  In order to solve the above-described problems, the outer wall structure of the present invention is a curtain wall type outer wall structure in which an outer wall panel is fixed to the outdoor side of a structural frame composed of column beams. A frame including a frame and a horizontal frame; and a frame insertion hole formed in a bottom portion of the frame and penetrating in a vertical direction. The frame insertion holes adjacent to the adjacent outer wall panels are adjacent to each other. The connecting plate having a hole through which the bolt located at the top is inserted and touching the bottom of the frame and through which the adjacent bolt passes is provided horizontally on the foundation upper member on the building foundation. A nut is screwed to the adjacent bolt below the connecting plate.

  If it is said structure, the nut of the lower side of the said connection plate can be turned, the attitude | position of the said connection plate can be adjusted, and the height adjustment of an adjacent outer wall panel can be performed simultaneously by this attitude | position adjustment. . Moreover, while transmitting the dead weight of the said outer wall panel to a building foundation, it becomes possible to transmit the wind pressure added to the said outer wall panel to the said member via the said connection plate.

  The bolt provided horizontally on the foundation upper member on the building foundation is a single bolt, and may be provided at a position on an intermediate vertical line of a hole through which the adjacent bolt passes. According to this, the connection plate can be rotated around the horizontal axis at a position on the intermediate vertical line of the adjacent bolts by the one bolt, so that the posture adjustment of the connection plate is facilitated.

  A part of the outer wall panel may be connected to the connection plate provided on the foundation upper member located between the building foundation and the column. According to this, the outer wall panel can be appropriately fixed to the housing even in the structure in which the columns are arranged at long span intervals. Moreover, the other part of the outer wall panel may be connected to the connection plate provided on the foundation upper member located at a place where the pillar does not exist. According to this, the mounting operation of the outer wall panel at the column arrangement location and the location without the column can be performed by the same quality operation of connecting to the connection plate.

  A bolt receiving plate having an area larger than that of the head may be provided between the head and the building foundation in the bolt arranged with the head down. According to this, it is possible to prevent a load from being concentrated on the building foundation by the head.

  With the outer wall structure of the present invention, the outer wall panel is positioned on the outdoor side of the building structural frame, and the height of adjacent outer wall panels can be easily adjusted.
