Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a floor panel for constructing a double floor structure.

(Prior art) In recent years, as office equipment such as computers has become more widely used, many cables have been laid and special cooling equipment has been installed not only in special buildings such as computer rooms but also in general office buildings. Double-floor structures for providing passages, etc. are becoming widely adopted.

A double floor is usually constructed by erecting a large number of support members on the floor of a building and laying a large number of floor panels on these support members.

The floor panels that make up the double floor are installed and function as a de facto floor surface, so they must have at least the same strength as a normal floor, but there is a large computer room on the floor panel. Since the device may be placed on the device, it is required to have sufficient strength to support such a heavy object.

However, since it is extremely rare that heavy objects are installed over the entire surface of a double floor, it is not necessary to provide a reinforcing structure to all floor panels.

From this point of view, it has been proposed to use free access flooring for seismic support, with reinforcing material placed on the back side as necessary, only in areas of double floors that require particularly high strength ( (Refer to Utility Model Application No. 105822/1983).

(Problems to be Solved by the Invention) However, the above-mentioned free access flooring for seismic support has a different configuration from flooring used for parts of double floors that do not require particularly high strength. To construct a double floor using the above-mentioned flooring materials, at least two types of flooring materials, ie, floor panels, are required.

Additionally, different types of support members may have to be provided to support floor panels of different configurations.

Furthermore, a floor panel having a reinforcing structure has a more complicated structure than one without a reinforcing structure, resulting in the disadvantage that the number of manufacturing steps increases and manufacturing becomes difficult. In addition, such floor panels are difficult to install manually due to their increased weight.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a floor panel that can improve the support strength of any part of a double floor as required, is easy to manufacture, has excellent mass productivity, and is easy to handle.

(Means for Solving the Problems) In order to achieve the above-mentioned object, the floor panel of the present invention has the following configuration. That is, the lower surface of the floor panel is formed with a support surface that engages with the strut member, and a plurality of four parts into which the plurality of protrusions arranged in parallel on the head of the strut member are inserted.

These recesses are formed at intervals that allow each of the plurality of protrusions of the strut member to be inserted when the strut member supporting the floor panel supports each floor panel without engaging other floor panels. In addition, when the support member supports a plurality of adjacent floor panels at the same time, the plurality of protrusions of the support support member are formed at positions where they can be respectively inserted into the recesses of these adjacent floor panels.

(Function) When supporting the floor panel of the present invention with a support member, it is possible to support any part of each individual floor panel, and also to support any part of a plurality of adjacent floor panels in common to these floor panels. It can be supported by a supporting column member. Therefore, since the double floor constructed from the floor panels of the present invention can be supported at any location by any number of support members, even though it is a double floor constructed from a single type of floor panel, First, there is an extremely high degree of freedom in selecting the reinforcement locations and reinforcement strength.

(Example) Embodiments of the present invention will be described below with reference to the drawings.
