Description

  The present invention relates to a connecting structure for a corner wall panel, and more specifically, for connecting the side edges of a pair of wall panels orthogonal to each other at a corner step surface of a floor pan via a joiner, for supporting a lower end portion of the joiner. The present invention relates to the structure of a joiner receiving member.

  Conventionally, when the side edges of a pair of wall panels are connected orthogonally at the corners having the same height, the hooks provided on the left and right sides of the substantially V-shaped joiner receiving member in plan view are provided at the corners. A structure is known in which the side edges of both wall panels are fitted and connected to the front opening of the joiner in a state where the lower end of the joiner is fitted into the fitting portion of the joiner receiving member while being hooked. For example, see Patent Document 1).

  However, the conventional joiner receiving member is limited to use in corner portions having the same height, and is not suitable for use in corner step surfaces having step surfaces with different vertical heights from the floor pan, for example.

  Therefore, in the course of reaching the present invention, the present inventor has developed a joiner receiving member 50 that can be used for the corner step surface 6 shown in FIG. As shown in FIG. 18, the joiner receiving member 50 has a different structure for left and right use. A left-side joiner receiving member 50A in FIG. 18A is provided with a fitting recess 20 in the left rear portion and a storage groove 62 in the right front portion, and the right joiner receiving member in FIG. 18B. 50B is provided with a fitting recess 20 in the right rear part and a storage groove 62 in the left front part. For example, when the left adjacent upper side wall panel 9A of the lower side wall panel 9B as shown in FIG. 19 and FIG. 20 is disposed, the left side joiner receiving member 50A of FIG. The lower end of the joiner 7 is fitted into the fitting portion 19 of the joiner receiving member 50A while being fitted to the rising piece 5 of the upper mounting portion 3, and the wall panels 9A and 9B are fitted to the locked portions 40 on both sides of the joiner 7. Each locking portion 15 is locked and connected, and the locking portion 15 of the lower side wall panel 9B can be stored in the storage groove 62 on the right side of the joiner receiving member 50A. On the contrary, when the upper side wall panel 9A adjacent to the right side of the lower side wall panel 9B is disposed, the wall panels 9A and 9B are joined to the joiner in the same manner using the left side joiner receiving member 50B of FIG. 7 to connect. In FIG. 19, 60 is a sealing agent, and 61 in FIG. 20 is a connection piece.

However, the joiner receiving member 50 used to support the joiner 7 has a different structure for the left side 50A and the right side 50B, and there is a problem that the number of parts increases and the manufacturing cost increases. In addition, since only the insertion recess 20 provided on either the left or right side of the joiner receiving member 50 is cantilevered by the rising piece 5, the attachment of the joiner receiving member 50 for supporting the joiner 7 is stable. There is also a problem that the nature is bad.
