Description

  The present invention relates to a panel connection structure in which a second panel is connected to an upper side of a first panel.

  Conventionally, as this type of panel continuous structure, in a panel comprising a panel body and an auxiliary panel continuously disposed above the panel body, an auxiliary panel using a concave portion of the head of the panel body is used. On the lower surface of the left and right pillars of the auxiliary panel, a knob that can rotate around the vertical axis and cannot move in the axial direction, and a bolt that rotates coaxially and integrally with the knob are arranged. A structure has been proposed in which a screw hole is provided on the upper surface of the pillar, and a bolt rotates when the user rotates a knob and is screwed into the screw hole to fix the auxiliary panel to the panel body ( For example, see Patent Document 1.)

  Further, in the continuous structure of the upper and lower panels, by fitting a downward projection provided on the lower end portion of the vertical frame of the upper panel having a downward U shape into the side opening of the lower panel from above. Connected to the lower panel, the inside of the vertical frame of the upper panel and the upper surface of the lower panel are connected with L-shaped brackets, and the panels adjacent to each other in the horizontal direction are screwed to the upper frame and the corner post. A structure for coupling has been proposed (for example, see Patent Document 2). Here, a pair of cap-like couplers that have the same shape and are fitted to the upper ends of the lower corner pillars and a part of the upper opening are used as the couplers for snap-engaging the corner pillars. There has been proposed one in which one surface of the tool is formed into a shape that can be fitted to each other at the time of reversal, and a surface that is fitted to the other column is provided with means for snap-engaging with the column.

  However, the continuous structure of Patent Document 1 is a structure in which a bolt provided at the lower end of the vertical frame of the auxiliary panel is screwed and fixed to the upper surface of the vertical frame of the panel body, and the fixing strength is not sufficient. As in Patent Document 2, the strength can be improved by fitting the downward projection on the lower end of the vertical frame of the upper panel to the lower panel and then connecting with an L-shaped bracket. It is necessary to provide an opening to be fitted in advance, and the corner strut connection structure is also very complicated. Further, when the panels are continuously provided, it is necessary to drill a screw hole for attaching the L-shaped metal fitting, so that the positioning of the upper panel is very difficult and there is a problem in workability.
