Abstract

PURPOSE:To increase the working efficiency, by parallelly arranging long size members supported on the lower side floor face by receiving metal fittings so as to be adjustable in the height and parallelly laying a number of panels on the long size members to form the upper side floor face. CONSTITUTION:Long size members 1 like rails supported so as to be adjustable in the height by receive metal fittings 4 provided with bolts 22 erected at both longitudinal ends are parallelly arranged to each other on the lower side concrete floor face 26. Both ends of rectangular panels 3 in plan view are received on the adjacent long size members 1 and the protruded part 11 of the cap 7 of panel 3 are fitted to the notches 13 of the long size members 1 to form the upper side floor face on the concrete floor face 26. Accordingly, a double- floor structure can be efficiently constructed in a short time.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a double-floor structure for laying wiring for devices such as computers and word processors when they are installed in an office.

[0002]

2. Description of the Related Art Recently, devices such as computers and word processors have tended to be used in many companies, and even in a newly built building, the floor in each room must be compatible with the installation of the above devices. A technique has been proposed in which a double-floor structure is used and wiring of the above-mentioned devices installed on the upper floor surface is laid in a space below the upper floor surface.

As an example thereof, in order to spread panels (tiles) having a square planar shape which constitute an upper floor surface on a concrete floor surface, in order to receive the corner portions of four adjacent panels at the same time, the concrete is A large number of legs with jacking function arranged and fixed on the floor surface at equal pitch, and four panels adjacent to each other at the upper end of each leg with the heights of the upper ends of these legs adjusted to be uniform. It is known that the panels are spread so as to receive the corners at the same time.

[0004]

However, in order to spread a large number of panels each having a square planar shape as described above, a large number of legs with jack functions are arranged and fixed, and the height of the upper end of each leg is increased. There was a problem that the work efficiency was very poor because it had to be adjusted so as to be uniform.

The present invention is intended to solve such problems, and an object thereof is to enable a double floor structure to be constructed efficiently and in a short time.

[0006]

SUMMARY OF THE INVENTION In order to solve this problem, the present invention has a structure in which lengthwise members whose lengthwise ends are supported by a receiving metal fitting on a lower floor surface are adjustable in height. The upper floor surface is formed on the lower floor surface by arranging a large number of the panels arranged side by side to receive both end portions of the planar rectangular panel on adjacent long members. Is the gist.

[0007]

With this structure, it is unnecessary to adjust the heights of the upper ends of the many leg members having the jack function to be uniform as in the conventional example, and the long member receives both ends of the panel. By doing so, the double floor structure can be efficiently constructed in a short time.
