Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an underfloor structure for forming an office floor assembly in a building construction or the like.

[0002]

2. Description of the Related Art Conventionally, for example, in U.S. Pat. No. 4,773,196, as a means for constructing a floor on a concrete slab for building construction, a unit flexible floor base material formed by connecting a number of support blocks with a flexible connecting medium is used. Using, a large number of the unit flexible floor base material is laid on the floor construction surface to form the floor base,
A method is known in which a large number of base plates are laid on the upper surface of the floor base, and a floor finishing material is laid on the upper surface of the base plate to construct a floor. By arranging them at intervals, a wiring path whose upper surface is closed by the base plate is formed.

[0003]

The above-mentioned flexible floor base material has an advantage that it can easily form a floor base without backlash by simply laying it on a construction surface such as a concrete slab in a building construction and absorbing irregularities. In addition, a wiring path can be formed under the base plate, which is suitable as a floor assembly structure for underfloor wiring of a computer in an office in a building.

However, since the above-mentioned conventional example has a structure in which the wiring paths are formed with the support blocks spaced apart from each other, the positions of the wiring paths are limited to the portions where the support blocks are spaced apart from each other.
Further, since the support block is a means for supporting the base plate and the heavy equipment installed in the office, it is originally preferable to arrange the blocks densely. In other words, it is not preferable to increase the interval for increasing the wiring path, If it is excessively expanded, the function as a strength member that supports heavy equipment is impaired. Therefore, it is difficult to increase the number of wiring paths and the space by the above conventional example.

The present invention is intended to solve the above problems and further reduce the weight of floor structural materials.

[0006]

As a means for achieving the above-mentioned object, the present invention provides means for achieving the above-mentioned object by arranging support blocks forming a floor base material at intervals and forming an underfloor wiring path between the blocks. A structure in which the support block is formed of a hollow member having a bottom plate and side plates raised from opposite edges of the bottom plate, and another wiring path passing through the inside of the support block is formed by utilizing the hollow structure. It was done.

[0007]

The above-mentioned support block has a hollow structure, and the cable is inserted into the support block (inside the wiring path) through the upper opening at the upper end of the side plate and is led out through the openings at both ends. That is,
A good wiring path is formed through the support block so that cables can be taken in and out.

A floor base plate or the like is laid on the upper end of the side plate to close the upper opening and close the wiring path in the support block. Furthermore, the present invention can use the wiring path formed between the support blocks, and can utilize the inside and outside of the support block, in other words, substantially the entire underfloor space as the wiring space.

Further, the side plate of the support block functions as a means for forming the above-mentioned wiring path and at the same time as a means for supporting the floor base plate soundly at its upper end. It can work.

Further, since the supporting block has a hollow structure, it is possible to significantly reduce the weight of the floor substructure material while using the supporting block as the wiring path.
