  However, in the fence member support structure as described above, when the protective fence having the fence member structure is installed on the inclined installation surface, there is not a little difference in the height between the fence members which are the surface units adjacent to the left and right. In order to alleviate this, it is necessary to manufacture a support column that adjusts the angle of the part that receives the surface unit of the support bracket for each inclination of the installation surface. The complexity of the surface increased, the efficiency was low, and there was a concern that manufacturing errors and construction differences would occur.

  The present invention is intended to provide a fence member support structure that can support the fence member with the same support structure even in a place where the inclination of the installation surface is different.

In order to achieve the above object, the present invention is configured as follows.
That is, in the fence member support structure according to the present invention, the plurality of support columns formed with the recessed grooves along the vertical direction are spaced from each other and the recessed grooves are opposed to each other, and the recessed grooves are erected on the installation surface. The fence member support structure is configured such that the left and right end portions are respectively inserted into the fence member and the fence member is supported by the support column, and the groove is inclined downwardly toward the opening of the groove. A support plate having an inclined surface is provided, and the fence member is supported on the inclined surface of the support plate.

  According to the fence member support structure according to the invention, a support plate portion provided with an inclined surface inclined downward toward the opening of the concave groove is provided in the concave groove, and the inclined surface of the support plate portion is provided. Even if the installation surface is inclined, by supporting the fence member on the inclined surface of the support plate portion, the fence members adjacent to the left and right are supported. Can be installed with few steps.

  The fence member support structure according to the present invention is characterized in that the support plate portion is provided in the concave groove through an attachment plate portion attached to the inner wall of the concave groove.

  According to the fence member support structure according to the invention, since the support plate portion is provided in the concave groove via the mounting plate portion attached to the inner wall of the concave groove, the fence member is provided in the concave groove. Can be easily supported inside.

  Moreover, the fence member support structure which concerns on this invention is provided with the said fence member provided with the fence member main body, and the overhang | projection piece protruded in the depth direction of the ditch | groove in the lower end part of this fence member main body, Is supported on the inclined surface of the support plate portion.

  According to the fence member support structure according to the invention, the fence member includes a fence member main body, and an overhanging piece projecting in a depth direction of the concave groove at a lower end portion of the fence member main body, Since the piece is supported on the inclined surface of the support plate portion, the end of the overhanging piece is disposed closer to the bottom of the concave groove than the lower end of the fence member main body. Compared with the case where the fence member which is not provided is supported on the inclined surface of the support plate portion, it is possible to prevent the fence member from falling downward, and to install the steps of the fence members adjacent to the left and right with fewer steps.

  Further, the fence member support structure according to the present invention has an attachment piece for attaching the overhanging piece to the lower end portion of the fence member main body in the longitudinal direction on the lower end portion of the fence member main body. The attachment piece is bent over at the side, and a curtain portion is formed to hide the gap formed between the lower end of the fence member and the installation surface on which the fence member is installed. It is characterized by being.

  According to the fence member support structure according to the invention, the attachment piece for attaching the extension piece to the lower end portion of the fence member main body is connected to the lower end portion of the fence member main body in the longitudinal direction continuously from the extension piece. And the attachment piece is bent at the side thereof to form a curtain portion that hides a gap formed between the lower end of the fence member and the installation surface on which the fence member is installed. Thus, the gap is hidden by the curtain portion, the appearance of the fence member support structure can be improved, and articles can be prevented from falling from the gap.

  According to the fence member support structure according to the present invention, a support plate portion provided with an inclined surface inclined downward toward the opening of the groove is provided in the groove, and the inclined surface of the support plate portion is provided. Even if the installation surface is inclined, by supporting the fence member on the inclined surface of the support plate portion, the fence members adjacent to the left and right are supported. Can be installed with few steps.
