Description

[Detailed description of the invention] (Industrial application field) This invention is a prefabricated flooring material that forms a double floor in a room where office equipment such as computers and word processors that require a lot of floor wiring work is installed. Regarding.

(Prior Art) Conventionally, many proposals have been made as prefabricated flooring materials that form a double floor for wiring. For example, in Utility Model Application No. 61-127241 proposed by the present applicant, there are locking holes provided at the four corners of the floorboards, and attachment/detachment holes in the engagement holes of adjacent floorboards between adjacent floorboards on the same plane. A support column is described that has a plurality of height-adjustable engagement portions that can be engaged with each other to closely connect and fix the floorboards.

(Problems to be solved by the invention) The above-mentioned conventional structure in which the floorboards and pillars are separate has the advantage of being able to adjust the unevenness of the floor surface caused by unevenness of the subfloor, etc. ,recently,
It is rapidly becoming popular.

However, when large office equipment and the like are installed on such a floor, a concentrated load may be applied to a portion of the floorboard, causing bending and deflection, and the floorboard is required to have a high load capacity.

Therefore, in order to improve the withstand load strength of the floorboard, it is possible to make the lower layer of the floorboard a thermosetting resin layer reinforced with glass fiber, carbon fiber, etc., but the material cost is high and the molding process is difficult. It would be wasteful to use such reinforced floorboards for the entire floor of an office due to the cumbersome nature of the construction.

In addition, since the concentrated load on the floorboards of large or small office equipment cannot necessarily be uniform, it is necessary to have a variety of reinforced floorboards with different strengths for different loads, and during construction work, office equipment cannot be installed. An amount corresponding to the floor area of the area to be used must be prepared each time.

An object of the present invention is to provide a prefabricated flooring material that does not cause the floorboards to bend even when large office equipment or the like is installed on a floor surface on which a double floor is formed.

(Means for Solving the Problems) The floor plate support structure for prefabricated flooring of the present invention consists of a plurality of floor plates that can form a double floor on the same plane at appropriate intervals upward from the floor base. , a locking hole provided in at least each corner of each of the floorboards and a locking hole of adjacent floorboards that can be adjacent on the same plane are removably engaged to closely connect the floorboards.・
In a prefabricated flooring material having a column with a plurality of engaging parts that can be fixed and whose height is adjustable, the floorboard is square, and cutouts are provided on the four sides of the floorboard, and the cutouts are shaped like a square. The notches are formed so that their positions, shapes, and dimensions are symmetrical with respect to any approximately diagonal line, and are engaged with the locking holes formed by the notches provided on the adjacent side surfaces of the floorboards. The present invention is characterized in that it has an auxiliary support column equipped with an auxiliary engaging portion whose height can be adjusted.

(Function) In order to create a double floor using the prefabricated flooring of the present invention, a plurality of height-adjustable engagement parts are installed on the subfloor where the corner parts of the plurality of floorboards butt against each other. The plurality of floorboards are provided with supporting posts erected, and the engaging portions of each of the supporting posts are removably engaged with locking holes provided at each corner of each of the plurality of floorboards, so that the posts can be adjacent to each other on the same plane. Connect and fix the floorboards closely together.

When the floorboards are connected and fixed in close contact with each other in this manner, engagement holes are formed by cutouts provided on the adjacent side surfaces of the floorboards.

The height of the part of the floor where office equipment is installed is adjusted by attaching the auxiliary engaging part of the auxiliary support to the notch in the floorboard from the side of one floorboard, and then attaching the notch in the side of the other floorboard. As a result, the auxiliary engaging portions of the auxiliary support columns are engaged with the engagement holes formed by the notches provided on the adjacent side surfaces of the floorboards, and the floorboards are supported by the auxiliary support columns.
