Intelligent building, which is a high-rise office building with comprehensive management and control functions including power distribution, substation distribution room, supervisory control room, and various communication services such as data communication and telephone conferencing, and information communication, disaster prevention, and methods. In an intelligent building, an electric line or an information communication line, which is complicatedly wired to an indoor floor, cannot be sufficiently accommodated for these runaway lines by a conventional floor buried pipe, and also for moving or expanding indoor installation devices. It was not possible to respond flexibly.

For example, access floors are used for accommodating electric information communication lines that are complicatedly wired to the indoor floor, as well as information processing and monitoring control rooms in office buildings or intelligent buildings. For light loads, there are many places where load strength is insufficient to be applied to equipment installed in electrical rooms (substations, switchboard rooms) such as substations, large plants, and buildings.

Such a conventional access floor is installed by mounting a cover, which is a bottom plate of a flat plate, on a support frame composed of a support that is adjustable in height and horizontal stringers connecting thereto or fixedly installed by a coupling means such as screwing. One double bottom structure is mentioned.

However, in such a structure, it is accompanied with the hassle of construction that the horizontal adjustment is to be carried out by using the height adjustment screws between the supports, and it is difficult to accurately level the floor without constructing the supporting frame without careful attention during construction. As the supporting loads are simply connected by the horizontal support material, the horizontal load strength is usually 1 ton / m 2, and the double flooring material for the actual load is inevitably required due to the weak load strength in the switchboard room. It was.

In addition, after installation, when a shock or concentrated load is applied from the outside, loosening of the adjusting screw and play may occur due to loosening of the adjustment screw or shortening of life due to permanent bending. It is implied.

In addition, the cover of the access floor is made of a variety of wooden structures, etc., but the bottom portion is bonded to the studs and use the edge finishing material (trim) so as not to peel off, such as impact load, such as stamping, scratches, cracks, etc. It is difficult to use it stably over a long period of time, and in particular, these stucco materials are difficult to maintain, and thus, the troublesome cover has to be replaced, and thus, the inconsistency between the new and old flooring materials and costs are accompanied.

On the other hand, there is a high load access floor of Utility Model No. 400012 registered in advance by the present applicant to solve this disadvantage.

According to the conventional high load access floor, there is a problem that the mechanical structure stability is deteriorated due to the occurrence of buckling phenomenon during high load transfer due to the c-shaped steel, and the construction is because the anchor bolt is not fixed to the concrete floor and embedded in the support. It is difficult to secure precision.

In addition, since the top plate, the support member, and the rib constituting the cover must be joined by welding, there is a disadvantage in that productivity is low and manufacturing cost is high.

In addition, the height adjustment of the cover is possible only in the anchor bolt, because the weight between the transverse weight is very difficult and difficult to adjust the height of the transverse by rotating the fixing nut in the state sandwiched between the anchor bolt.

The present invention is to solve the above-mentioned conventional problems, double flooring material for electrical rooms that can solve the problem of the lack of load strength of the double flooring material that requires a high load strength in accordance with the heavy load in and out of the electrical room, such as power generation, substation, building, factory The purpose is to provide.

In addition, another object of the present invention is to improve the structure of the top plate to facilitate the manufacture.

Another object of the present invention is to facilitate the height adjustment of the cover.
