Description

[Detailed description of the invention] [Industrial application field] The present invention relates to the improvement of the connecting structure between columns and horizontal bars. This invention relates to a connecting structure between a support and a horizontal beam for constructing a frame structure such as a device.

[Conventional technology]

2. Description of the Related Art Various types of structures for connecting columns and horizontal beams are available for constructing framework structures such as conventional shelving devices and partitioning devices. For example, as disclosed in Utility Model Application Publication No. 51795 of 1981, a locking piece of a support arm is fitted and locked into a locking hole formed on the side of a column whose outer periphery is covered with a decorative cover. Then, the supporting arm is fitted and locked so that it extends substantially perpendicularly to the pillar, and the part of the supporting arm that protrudes from the pillar is fitted into the core of the horizontal beam, and the screw is screwed in from the side. A device is provided in which the connecting part and the core are fixed with a decorative cover to improve the appearance, but the support arm is only fitted and locked to the support column, and the support arm is not accidentally attached to the horizontal beam. If an external force is applied upwards, there is a risk that the horizontal beam may come off the support, so in practice, after a frame structure is constructed by connecting the horizontal beam to the support, the height of the support is often adjusted up and down. In this case, it is a particularly important problem that the horizontal beam often comes off the support, and the work of attaching decorative covers to the connecting parts and horizontal beams to improve the appearance is time-consuming and costly. There were some problems.

[Problem that the invention attempts to solve]

In view of the above-mentioned situation, the present invention aims to solve the problem by making it possible to easily connect the column and the horizontal beam with a simple operation, firmly and without wobbling, and at the same time, the connecting part cannot be completely viewed directly from the outside. This makes it possible to improve the appearance, and even if the height of the column is adjusted up and down after connecting the column to the column, there is no fear that the column will come off at all, and the column and column are easy to assemble. The point is that it provides a connecting part structure.

[Means for solving problems]

In order to solve the above-mentioned problem, the present invention fixes mounting members having a substantially L-shaped cross section to the four corners of a tubular support base having a square cross section, and attaches a decorative cover to the mounting member that is approximately divided into four parts in plan view. Attached at intervals over the entire length, a slit opening upward is formed at the center of the side surface facing the gap between the decorative covers adjacent to the upper end of the support base, and screw holes are formed on both sides of the slit. A hole is bored in a locking piece that has a slit that opens downward and can be fitted into the slit in the support base, and that contacts the side surface of the support base and corresponds to the screw hole. a connecting fitting formed by orthogonally forming a mounting piece and a connecting piece extending from an outer end of the locking piece with a connecting hole; and a connecting hole in the connecting piece that comes into contact with the connecting piece of the connecting piece. A connecting structure between the column and the horizontal beam is composed of a horizontal beam having a fixing piece with a connecting hole in communication with the horizontal beam inside the side end.

[Effect]

The connecting structure of the column and horizontal beam of the present invention having the above-mentioned contents is such that the locking piece of the connecting fitting is fitted into the slit of the column base, and the screw inserted through the hole of the mounting piece is inserted into the column base. The connecting piece of the connecting fitting can be screwed into and fixed in the screw hole to allow the connecting piece of the connecting fitting to protrude laterally from the gap of the decorative cover attached to the outer periphery of the support base, and the decorative cover fixes the connecting metal fitting to the support base. The connecting piece can be slid up and down in any state, and the connecting piece can be brought into contact with the fixed piece at the end of the horizontal crosspiece, and the bolt can be inserted into the connecting hole of the connecting piece and the connecting hole of the fixed piece, and the nut can be screwed together. The horizontal beam can be easily connected to the support.
