Description

TECHNICAL FIELD The present invention relates to a fixing structure for a spandrel panel.

The spandrel walls of a building's balcony form a fixed structure by fixing the legs of the spandrel panels to the balcony floor beams that protrude from the structural frame (main tower) consisting of the building's pillars and beams. ing. The spandrel wall panel is constructed by attaching an exterior material via a base material to both wide sides of a spandrel frame in which an upper piece, a lower piece, and left and right side pieces are assembled in a frame shape. For example, in a building such as a steel-framed house, the spandrel frame is a steel frame material, and exterior materials formed of various siding materials are attached to the steel spandrel frame to form the spandrel panel. Configured.

Regarding the fixed structure of the spandrel frame, spanned spandrel frame, spanned spandrel frame fixing member with spanned spandrel interlocking plate fixed vertically on the surface of joining plate material, beam joined to balcony beam made of H-beam. Fixing structures have been proposed with interlocking members. In this fixing structure, the back surface of the joining plate member of the spandrel frame fixing member is joined to the beam interlocking member, and the adjacent spandrel frames are fixed to the spandrel joint plate at the lower side of the vertical frame. Adjacent quay frames are fixed at their lower sides to quay wall tie-plates to construct a balcony with no pillar structure. Therefore, it is possible to easily ensure waterproofness without causing the problem of interference between the column fixing part using the upper surface of the upper flange of the balcony beam and the waterproof construction material of the balcony floor (see, for example, Patent Document 1).
