  The above-mentioned patent document 1 only discloses a positioning technique for the base material (vertical trunk edge) of the outer wall panel. Here, with respect to the outer wall surface material of the outer wall panel, when the outer wall surface material is disposed on the upper side of the fixed lower outer wall surface material, the upper wall surface material on the upper side is pressed to exert downward force. It is conceivable that the upper outer wall surface material is fixed to the base material when the joint width (vertical interval) between the lower outer wall surface material and the upper outer wall surface material reaches a predetermined dimension. .

  In this case, there is an opening of a distance of about the vertical dimension of the outer wall surface material between the work eye line when pressing the upper end of the upper outer wall material and the work eye line when measuring the joint width. Become. For this reason, it is not easy to adjust the position of the outer wall surface material while measuring the joint width by one worker, and the cost increases if a plurality of workers are used. .

  This invention makes it a subject to provide the manufacturing method of the groundwork stand which can position the outer wall surface material of an outer wall panel accurately, and an outer wall panel in view of said situation.

  In order to solve the above-mentioned problem, the ground frame of the present invention is a place different from the mounting position of the building frame to which the outer wall panel is attached, by arranging the outer wall panel in which a plurality of outer wall materials are arranged vertically and connected by a base material. And a position reference part for performing at least one of vertical interval alignment and side surface alignment of the plurality of outer wall surface materials.

  According to the above configuration, since the ground frame has the position reference portion for performing at least one of the vertical interval alignment and the side surface alignment of the plurality of outer wall materials, the positioning of the outer wall materials of the outer wall panel can be accurately performed. It will be possible.

  As the position reference portion, a mark may be attached at a position where the upper end of the outer wall surface material is positioned at a position where the outer wall surface material is fixed to the base material. According to this, the operator presses the upper end of the outer wall surface material with a jig or the like, and aligns the upper end with the position of the mark so that the space between the lower outer wall surface material and the upper outer wall surface material is reduced. The joint width (vertical spacing) can be adjusted to a specified value. Therefore, there is no need to directly measure the joint width of the upper and lower outer wall materials, and for example, it is easy to fix the outer wall material while adjusting the joint width to a specified value by one worker. Become.

  The said mark may be attached | subjected to the surface of the front side of the support | pillar part located in the rear surface side of the said outer wall surface material.

  The position reference portion may include a contact portion that contacts a side surface portion on the front side of the protrusion so as not to interfere with the protrusion existing on the side surface of the outer wall surface material. According to this, the side surface alignment of the outer wall surface material by the contact portion which is the position reference portion can be performed with reference to the front side of the noticeable outer wall surface material.

  The said contact part may be provided in the support | pillar part or beam part which comprises the said groundwork stand.

  Further, according to the manufacturing method of the outer wall panel of the present invention, an outer wall panel in which a plurality of outer wall materials are arranged in a vertical direction and connected by a base material is assembled on a ground for assembling at a place different from a mounting position of a building frame to which the outer wall panel is attached. A method for producing an outer wall panel using an assembling stand, wherein the ground assembling stand is marked at a position where an upper end of the outer wall surface material is located at a position where the outer wall surface material is fixed to the base material. The upper end of the outer wall surface material is pressed downward, and the upper end of the outer wall surface material is fixed to the base material in accordance with the position of the mark.

  According to the above method, the operator holds the upper end of the outer wall surface material with a jig or the like, and aligns the upper end with the position of the mark so that the lower outer wall surface material and the upper outer wall surface material are aligned. The width of the joints can be adjusted to the specified value. Therefore, there is no need to directly measure the joint width of the upper and lower outer wall materials, and for example, it is easy to fix the outer wall material while adjusting the joint width to a specified value by one worker. Become.

  In the above method, when the upper end of the outer wall surface material is composed of two convex portions having the same height divided in the front and rear, the front convex portion may be aligned with the position of the mark. According to this, the joint size adjustment of the outer wall surface material by the mark is performed with reference to the front side of the noticeable outer wall surface material.
