Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an extruded column used as a supporting device for supporting a floor panel when constructing a system floor, for example.

[0002]

2. Description of the Related Art Conventionally, as a system floor used for underfloor shield wiring of power cables, signal cables, etc. of various devices for realizing office automation, a rectangular floor base laid on a foundation floor has been used. Protrusions protruding upward are provided at the four corners, the four corners of the floor panel are supported by these props, and the floor panel is laid apart from the floor base, and the various types of equipment are provided in the gap between the floor base and the floor panel. It is known that the electric power cables, signal cables, etc. of the above have been shielded.

However, since the floor base has a flat bottom surface, if it is not laid in surface contact with the base floor, rattling occurs and the conformability to the base floor is impaired.
At this time, in order to lay the floor base on the same plane in a stable state, high flatness accuracy is required for the surface finish of the foundation floor surface, which causes problems in various aspects such as construction cost, construction period and workability. Occurs.

Further, the structure is such that columns are erected at the four corners of the floor base, and the floor panels are laid so as to support the four corners of the floor panel on these columns. If the four columns are not at the same height, the floor panel rattles. In addition, even if the four columns are at the same height, the floor panels cannot be laid stably on the same plane even if the floor panels have a slight warp deformation or a variation in the plate thickness. As described above, the conventional system floor is required to have high flatness accuracy of the foundation floor surface and high molding precision of the floor base and the floor panel.

The support pillars for supporting the floor panel are generally molded by aluminum die casting. That is, the support column is provided with four support portions, and screw holes are vertically formed in these support portions. A bolt as a height adjusting member for supporting the floor panel is screwed into the screw hole.

Therefore, the height of the floor panel can be adjusted by adjusting the screwing depth of the bolt into the screw hole. Even if the floor panel has a slight warp deformation or a variation in plate thickness, the floor panel can be adjusted. Can be laid in a stable state on the same plane.

[0007]

However, it is necessary to perform post-processing for forming a screw hole in the supporting portion after forming the pillar by aluminum die casting, which causes a cost increase. Also, since the support part with screw holes is made of aluminum and the bolts that form the height adjustment member are usually made of iron or brass, the height adjustment member is screwed to the height adjustment member by vibration or impact applied from the floor panel. It is uneconomical because the thread of the screw hole is easily damaged, and if the thread is damaged, it is necessary to replace the entire column with a new one.

The present invention has been made in view of the above circumstances, and an object thereof is to easily manufacture a column for supporting a floor panel or the like, and to reduce the cost.
Another object is to provide an extruded column that is lightweight and can be used for skyscrapers.

[0009]

In order to achieve the above-mentioned object, the present invention provides a support body integrally formed by extrusion molding of a light metal, a plurality of support portions, and a bridge connecting these support portions. And a fitting hole penetrating in the axial direction of the strut body is provided in the support portion.
By extruding the pillar body and then cutting it into a predetermined length, molded pillars having the same shape can be manufactured, and mass production becomes possible. Further, the plurality of supporting portions can be separated from the bridge portion, and the other supporting portions can be removed while leaving the necessary supporting portion.

By forming the fitting hole into a non-circular shape in which a flat surface is provided on a part of the inner peripheral surface of a perfect circle, when this pillar is used for supporting a floor panel, a screw is vertically inserted into the fitting hole. A support cylinder having a hole can be inserted, and a height adjusting member having a panel support portion can be screwed into the screw hole of the support cylinder.
Therefore, even if the thread of the screw hole that supports the height adjusting member is damaged by the vibration or impact applied from the floor panel, only the support cylinder needs to be replaced.
