Description

TECHNICAL FIELD The present invention relates to a floor plate support for lifting and supporting a floor plate on a floor surface to form a double floor structure used as a floor of a computer room or the like.

Conventional techniques and problems of the invention The floor board support for the double floor structure that has been conventionally used is
A floor plate is placed on a column upright on the floor surface to fit a pedestal, and a fixing screw is screwed into the pedestal from a side to fix the pedestal.

In this floor board support, the height of the floor board must be adjusted from the side. Therefore, once the floor is completed, the floor board must be removed to readjust the height of the floor board. For this reason, the height adjustment work is complicated, and it is practically possible to eliminate this rattling by adjusting the height of the floor plate, for example, when rattling occurs after placing the equipment on the floor. It is impossible.

An object of the present invention is to eliminate this inconvenience, and to obtain a floor board supporting member whose height can be easily adjusted from the floor board without removing the floor board once provided. Further, the conventional support tool is difficult to be positioned during its construction, or is unsatisfactory in stability and the like when an uneven load is applied with only a part of the floor board placed thereon. The present invention aims to improve the handling even during such construction.

MEANS FOR SOLVING THE PROBLEM The present invention has a pedestal formed by bulging a central portion of a metal circular plate upward, and is formed at four peripheral ends of the pedestal so that the orthogonal center line is formed. The centering notch shown, a mounting hole provided in the peripheral portion of the pedestal for allowing a nailing nail to pass therethrough or causing the adhesive to overflow, and a collar portion formed at the lower end portion of the pedestal. Abut on the upper surface, penetrate the lower end through the hole formed in the center of the pedestal, and apply a washer with a hole with a smaller diameter than the hole of the pedestal to the lower surface of the pedestal to caulk the lower end and fix the pedestal to the brim. It is clamped and held upright, and deformation due to caulking is prevented from reaching the pedestal part, allowing it to rotate with respect to the pedestal, and the lower end separates from the floor surface and rotates even when adhesive is applied to the floor surface. A pillar that ensures movement, and a male screw formed on the outer periphery of the upper end of this pillar, It is screwed to this male screw and it is formed on the pedestal on which the floor board is placed and the tip of the stanchion. It engages with a tool such as a screwdriver and rotates the stanchion from above to adjust the height of the cradle. And a detachable cover having an upper end portion of the column and a substantially flat surface on the floor plate.

In addition to having a flat surface, the pedestal may be formed with a protrusion that fits into the gap on the lower surface of the abutting portion of the floor plate to prevent rotation of the pedestal. It should be noted that a floor plate whose end face is slightly inclined and a gap is formed on the lower surface of the abutting portion is already widely used.

The projection used here is, for example, one formed by bending a part of the pedestal upward by pressing, or by inserting a projection member into a hole provided in the pedestal and holding it by frictional force,
When the projection is not necessary, a material that can push the projection member from above to make the surface of the pedestal flat is used.

A cushion material such as rubber may be provided on the surface of the pedestal.

The cover may have any configuration as long as it covers the upper end of the support pillar and makes the floor plate substantially flat.For example, a flat plate portion in contact with the upper surface of the floor plate, a central upper surface of this flat plate portion, and a screwdriver It has an engaging hole that engages with tools such as to be rotated, and a female thread part that fits into the upper end of the male thread of the column.
It can be made to be rotatable and removable by using the engaging hole.

Action In the floor plate support having the above-described structure, the height of the pedestal, that is, the floor plate can be adjusted by removing the cover and rotating the support from above using the engaging portion.

Since the pedestal is provided with a notch for centering, a centerline is drawn on the floor surface, and the centerline is installed so as to facilitate the construction.

Since the pedestal is clamped at the lower end of the support by caulking, the support does not tilt even when only part of the floor plate is placed during construction and an uneven load is applied. In addition,
Although caulking is carried out, a washer is used and the hole of this washer is smaller than the hole of the pedestal, so that the deformation of the column due to caulking does not extend to the hole portion of the pedestal, and the column can be rotated. Further, when the pedestal is provided with a protrusion, the pedestal is prevented from rotating due to vibration or the like due to long-term use and changing in height to cause rattling.

Further, when a cushioning material is provided, rattling can be better prevented.
