Description

  The present invention relates to an article attachment structure for attaching an article to be connected to a support via an attachment member.

  Conventionally, various configurations have been conceived in which an attachment member is provided on an article to be connected, and the article to be connected is attached to a support via the attachment member.

As an example of such a configuration, for example, the mounting member has a contact surface that comes into contact with the support column, and the female screw hole formed in the support column and the female screw hole in a state where the contact surface is in contact with the support column. There has been considered an aspect in which a mounting member is connected to a column using a bolt that can be screwed and can be screwed back and forth along the normal direction of the surface of the column (see, for example, Patent Document 1).
JP 2006-105180 A

  By the way, in the configuration described in Patent Document 1, a female screw hole is formed in the outer wall of the column, and a bolt is screwed into the female screw hole, and the bolt is fastened to the mounting member by the column and the column provided with the female screw hole. Force is applied.

  However, when receiving an impact such as when an object or the like collides with the support column, an action of separating the support column and the article to be connected from each other works. In addition, when the article to be connected is placed horizontally between the columns, the weight of the article to be connected also acts as an action to be separated from the columns. If such an action is received, the fastening between the female screw hole provided in the support column and the bolt is loosened, which may cause a problem that the stability of the structure is lowered.

  In order to solve such a problem, the present invention makes it difficult to loosen the bolts and nuts with the bolts and nuts attached to the columns using bolts and nuts. It is configured to be stably attached.

  That is, the article mounting structure according to the present invention is provided on a support column that includes an inner wall, an outer wall, and a cavity formed between the inner wall and the outer wall, and an article to be connected that is an article to be connected to the support column. A mounting member abutting on the outer wall, a nut member abutted on the inner wall of the support column, and a bolt for tightening the mounting member to the nut member via the inner wall and the outer wall of the support column. .

  In such a case, since a cavity is formed between the inner wall and the outer wall, when the attachment member is attached to the support column via the bolt, the attachment member and the nut member are brought into close contact with each other by the fastening force. The bolts and nuts can be prevented from loosening due to the elastic repulsive force of the inner wall and the outer wall. In the present invention, “providing the attachment member on the connection target article” means a mode in which the attachment member configured separately from the connection target article is provided on the connection target article, and the connection target article and the attachment member are integrally configured. It is a concept that includes both of the aspects to be performed.

  An example of a configuration for effectively using the cavity includes an outer wall having an opening for communicating the cavity with the outside. If it is such, a wiring can be inserted in a cavity from an opening part, for example, and this cavity can be utilized as a wiring penetration space.

  The mounting member is provided with a fitting convex part for fitting to the opening and positioning with the pillar as a configuration that can effectively reduce the trouble of attaching the mounting member to the pillar. Is mentioned. This is because the attachment member can be temporarily fixed to the support column.

  As an effective configuration for improving workability, a cover is configured to be detachable from the opening of the outer wall, and an outer end portion of the fixing portion for fixing between the nut member and the inner wall of the column Is arranged in the cavity. In such a case, the entire area of the fastening portion is disposed on the inside of the outer wall of the support column, so that the cover can be attached to the support column while the nut member is fixed to the support column.

  As a configuration that is particularly effective when the article to be connected is a member that extends in the horizontal direction, a female screw hole that is paired with the nut member is provided, and a support column is provided by a pair of bolts that can be screwed into the female screw hole. The bolts are inclined so that the axial centers of these bolts are symmetrical with respect to the normal line of the outer surface of the column. This is because the articles to be connected can be prevented from inclining by preventing the tightening force from being biased to either side of the upright direction of the support column.

  As a configuration that can effectively reduce the labor for attaching the nut member to the support column, one having a locking claw that can be engaged with the upper end portion of the inner wall of the support column at the upper end portion of the nut member can be cited. . This is because with such a configuration, the nut member can be temporarily fixed to the support column.

  According to the article mounting structure according to the present invention, since there is a cavity between the inner wall and the outer wall, when the mounting member is attached to the column via the bolt, the mounting member and the nut member come together due to the fastening force. The bolts and the nuts are less likely to loosen due to the elastic repulsive force of the inner wall and the outer wall.

Since it is arranged in the cavity 1 s, the entire area of the fastening portion is arranged inside the outer wall 15 of the support column 1, and the cover 12 can be attached to the support column body 11 while the nut member 4 is fixed to the support column 1. Therefore, workability can be improved.

  The nut member 4 is provided with a first female screw hole 4x, and the attachment member 3 is attached to the support column 1 with a pair of attachment member fixing bolts 5 that can be screwed into the first female screw hole 4x. Since the axial centers of these bolts 5 are inclined so as to be line symmetric with respect to the normal line of the outer surface of the column 1, the tightening force is not biased to either side of the column 1 in the upright direction. It can control that material 2 inclines.

  In addition, since the upper end portion of the nut member 4 has a locking claw 42 that can be engaged with the upper end portion of the inner wall 14 of the column 1, the nut member 4 can be temporarily fixed to the column 1. The effort at the time of attaching the nut member 4 to the support | pillar 1 can be reduced effectively.
