Therefore, in order to rationally store the power, telephone and data cables and prevent the cables from being cut,
Various prefabricated floor structures as shown in FIGS. 13 and 14 are provided.

In this conventional assembly type floor structure, a plurality of support legs 1 ... Are erected at predetermined positions on the floor surface F of the office, and a plurality of floor panels 2 are mounted between the support legs 1. It is placed. The supporting legs 1 ... are a columnar main leg portion 3 provided vertically, and a base portion 4 which is provided at a lower end portion of the main leg portion 3 and is fixed to the floor F by a connecting pin 5. , And a pedestal portion 6 provided on the upper end portion of the main leg portion 3. On the other hand, the floor panel 2 is in the shape of a square plate made of non-combustible material, and the lower surface of each of the four partition portions is placed and fixed on the pedestal portion 6 of each of the support legs 1 so as to be supported at four points. Is becoming

A substantially trapezoidal recessed fitting portion 35b is provided on the outer peripheral edge on the other side. Further, a substantially triangular through hole 35c is formed in the center for the purpose of weight reduction and the like, and an inner peripheral portion thereof is bent downward. Further, the positioning member 13 is set so that the entire positioning portion 35 projects from the corners of the bottom surface 20 of the floor member 11 when the positioning member 13 is projected to the outside, and the lower surface 35d of the positioning portion 35 supports the leg. Bottom 2 of 12
It is set to be on the same plane as 3a.

Further, the floor members 11, 11 that are adjacent to each other and face each other
6, a wiring groove 37 having a width of about 75 mm is formed via the positioning portions 35, 35, and the upper portion of the wiring groove 37 has a rectangular shape. It is designed to be closed by a lid member.

Therefore, according to this embodiment, when the floor members 11 are arranged on the floor surface F through the supporting legs 12, marking is performed in advance for positioning on the floor surface F. .. Then, arrange each floor member 11 at a predetermined position,
At this time, when the positioning members 13, which are respectively folded inside the floor member 11, are pulled downward by hand as shown in FIG. 12, the respective projections 31, 31, ... And the locking holes 36b, 36.
The engagement with b ... Is released, and the outward rotation is allowed via the pivot pins 30, 30. Therefore, if the positioning members 13 ... Are maximally rotated outward, the locking holes 36b, 36b ...
The positioning portions 35 ... Project from the four corners of the floor member 11 while being retained in a horizontal state by being locked to 1, 31 ,.

Then, the floor members 11 ...
The concave fitting portions 3 of the adjacent positioning portions 35 ...
5a and the convex fitting portion 35b are fitted to each other, and the positioning is sequentially performed, and the respective pieces are combined from the horizontal direction. As a result, wiring patterns 37 having a checkerboard pattern are provided between the floor members 11 ...
Is formed, and after wiring data cables etc. here,
When the cover member is covered, the whole assembly work is completed.

Thus, in this embodiment, the support legs 12 ...
, The floor members 11 ...
Since they are simply arranged on the top (laying down), the structure is simplified and the assembly work is not only extremely easy, but the manufacturing work is also easy.

Moreover, when a step is generated between the floor members 11 due to the step on the floor surface F, OA equipment is placed on the upper surface of each floor member 11, or When a load is applied from above by a person being placed, the thin portions 29, 29 ... Of the support legs 12 ... Are cut from the shearing direction due to the difference in the magnitude of the relative load with respect to the dividing elements 16, 17. , Narrow bridge-shaped pieces are also bent and deformed into a crank shape. Therefore, the elastic member 32 changes the amount of compressive deformation according to the magnitude of the relative load,
That is, since the load on the high-order side split element is increased, the amount of compressive deformation is increased, and both end portions 12a of the support leg 12 are
12b individually move up and down to lower the dividing element at the higher position. Therefore, the step difference between the dividing elements 16 and 17 is automatically absorbed, and the step difference between the floor members 11 is also absorbed, so that the upper surfaces are flush with each other. As a result,
After combining the floor members 11 ..., fine adjustment of the step like the conventional case is not required, the combination work efficiency is further improved, and the cost increase can be suppressed.

Further, since the positioning member 13 is formed separately from the floor member 11 as shown in FIG. 12 and can be folded inward with respect to the floor member 11, the positioning member 13 and the floor member 11 are integrated. The yield of the material during manufacturing becomes better than that in the case of forming the above. Also, when packing the floor member 11, the positioning member 13
Since it can be folded inside the lower surface 20 of the floor member 11 so as to prevent the outward projection, the packing work can be facilitated, and the packed product can be made compact, and the efficiency of receiving and shipping work can be improved and the product can be stored in a warehouse. Space saving can be achieved during storage.

It should be noted that the present invention is not limited to the above-mentioned embodiment, but it is also possible to form the dividing elements into small squares instead of triangles, and to connect the positioning members with pivot pins. Instead, it is possible to detachably form the lower surface of the floor member only by using the engagement between the protrusions 31 and 31 and the engagement holes 36b and 36b. It is also possible to simply connect both ends with elastic members without providing a thin portion or a bridge piece on the support leg.

[0025]

As is apparent from the above description, according to the assembled floor structure of the present invention, in particular, one floor member is divided into a plurality of parts, and each of the dividing elements is provided on each divided opposing edge side. Support legs are laid across the lower end, and the lower surfaces of both ends of the support legs that can be divided from the approximate center position are connected by elastic members, which simplifies the structure and simplifies the manufacturing work, as well as the floor surface. The assembling work on the top becomes easy, and the overall work efficiency can be improved and the cost can be greatly reduced.

Moreover, by connecting each of the dividing elements with the elastic member via the supporting leg, the step between the dividing elements can be automatically absorbed, so that the assembling work is further improved. It is possible to sufficiently suppress the cost increase.
