In order to solve the above-mentioned problems, according to the present invention, an outer wall panel is formed by attaching an exterior surface material to a rectangular frame member, and upper and lower corner portions of one side edge of the outer wall panel are formed. A waterproof tape having an adhesive property is also attached to the front side so as to cover two surfaces perpendicular to each other at the corner, and the outer wall panel except for the one side edge extends between the rectangular frame material and the exterior surface material. As described above, a waterproof tape having no adhesive property is attached to the front side, and the outer wall panels are fixed with the vertical joint material attached to the one side edge between the adjacent outer wall panels. According to this configuration,
Since a waterproof tape having an adhesive property is provided also on the surface side at a corner portion of one side edge where the vertical joint material is provided, the vertical joint material has good adhesiveness and the vertical joint material can be easily attached.

It is preferable that the adhesive strength on the front side of the waterproof tape provided at the corner is smaller than the adhesive strength on the back side. When attaching the vertical joint, when removing it for fine adjustment, etc., once the vertical joint is attached, the back side has a stronger adhesive force than the front side, so the waterproof tape does not peel off from the outer wall panel side. Only the material can be removed. Further, since the adhesive force on the surface side is weak, dust and the like hardly adhere.

[0006] Both ends of the waterproof tape provided on the outer wall panel peripheral edge except for one side edge provided with the vertical joint material are superimposed on the waterproof tape having an adhesive property also on the front surface provided in the corner portion. Is preferred. Since the end of the waterproof tape which is located at the corner and is easily peeled off is overlapped with the waterproof tape having adhesiveness on the surface side, the end of the waterproof tape is hardly peeled off.

The present invention has been described above. An outer wall panel is constructed by attaching an exterior surface material to a rectangular frame member, and two upper and lower corners on one side edge of the outer wall panel are perpendicular to each other. Adhesive waterproof tape is also attached on the front side so as to cover the surface, and the front side is adhered to the peripheral edge of the outer wall panel except for the one side edge so as to extend between the rectangular frame material and the exterior face material. A waterproof tape having no property is attached, and the outer wall panel is fixed with the vertical joint material attached to the one side edge between adjacent outer wall panels. According to this configuration, a waterproof tape having adhesiveness is also provided on the front surface side at the corner portion of one side edge where the vertical joint material is provided, so that the vertical joint material has good adhesion and the vertical joint material is easily attached. Thus, the outer wall panel can be efficiently attached.

By making the adhesive strength on the front side of the waterproof tape provided at the corner part smaller than the adhesive strength on the back side, the longitudinal joint material once attached at the time of mounting the longitudinal joint material is removed for fine adjustment or the like. In this case, since the adhesive strength is stronger on the back side than on the front side, only the vertical joint material can be removed without removing the waterproof tape from the outer wall panel side. Further, since the adhesive force on the surface side is weak, dust and the like hardly adhere.

[0018] Both ends of a waterproof tape provided on an outer wall panel peripheral edge excluding one side edge provided with a vertical joint material are laminated on a waterproof tape having an adhesive property also on a surface side provided on a corner portion. Since the end of the waterproof tape, which is located at the corner and is easily peeled off, is overlapped with the waterproof tape having an adhesive property on the surface side, the end of the waterproof tape is hardly peeled off, so that reliable waterproofness can be maintained.
