Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present application relates to a method for installing a floor panel laying member that is laid with a necessary space between it and a floor panel.

Conventional technology Conventionally, a laying member that supports a floor panel that constitutes a floor surface is laid so as to have a space necessary for arranging communication cables, power lines, etc. between it and a floor plate made of concrete or the like. is known, and the conventional laying member is provided with a support plate having an adjuster for height adjustment, and this laying member is positioned at the intersection of four rectangular floor panels. A large number of them are installed in a grid pattern on the floorboard,
A large number of floor panels are laid by placing each corner of the four floor panels on the support plate of each of the installed laying members.

Problems to be Solved by the Invention However, according to the conventional configuration, it is not only necessary to adjust many adjusters to maintain a horizontal reference for the entire floor surface, but also to support the corners of the four floor panels. Adjusting one adjuster star has a chain reaction effect on the other adjuster stars supporting the other corners of the four floor panels, making the adjustment operation extremely complicated and troublesome. Since it is necessary to have a structure in which the support plate does not rotate when the adjustment is made, the mechanical structure for rotatably attaching the support plate to the adjuster is also troublesome.

Therefore, in order to improve the above-mentioned defects of the conventional product, the applicant of the present application has developed a bottom plate that is elongated in the left-right direction and has an upwardly U-shaped longitudinal section, and that has multiple locations along the length of the bottom plate. A fixed leg is fixed on a floor board with a pair of long holes in the front and rear separated to match the laying pitch of the floor panel. are inserted into the pair of front and rear elongated holes of the fixed leg and screwed into the upper plate of the short leg piece that comes in contact with the floorboard, extending vertically and having a support plate integrally provided at the upper end. It has a plurality of support members and front and rear plates guided by the front and rear plates of the fixed legs, and is elongated in the left-right direction and has a downward U-shape in longitudinal section, and the lower surface of the upper plate is above the support plate of the support member. The present invention has developed a floor panel installation member that is supported by a floor panel, and is comprised of a lifting leg having a plurality of operating holes on the upper surface for rotating the screw member, and has already filed an application. By the way, when laying the laying members configured in this way on a floor board, for example, in the left and right (horizontal) direction of the room, it is necessary to have a square shape with an interval equal to the length of one side of the floor panel, and the end surfaces are straight. In other words, the spaces between the laying members should be aligned so that they are parallel to each other on the line, and in the front-rear (vertical) direction, the intervals between the laying members are slightly shorter than the length of one side of the floor panel. A large number of them are arranged to create a space that communicates with the
If you are using this space to run a communication cable that connects OA equipment with a power supply and signal input/output source, for example, if you are going to route the communication cable diagonally, you should run the cable at a right angle. Not only does this require long communication cables, but it also makes wiring work difficult when the communication cables are thick or require avoiding large bends, such as optical cables. There was an inconvenience.
