Description

[Detailed explanation of the invention] [Industrial application field] The invention aims to improve free access floors, specifically, to simplify the installation work, increase load strength, and change equipment such as wiring and piping under the floor. This refers to a practical raised floor that can be easily repaired or remodeled by opening the floorboard at the desired location when the need arises, and where many electronic devices such as computers and word processors are installed. It will be widely used as a floor structure in modern offices.

[Conventional technology and problems to be solved]

As is well known, the floors of offices, etc. where electronic control equipment such as computers are installed have a double floor structure called a "free access floor", and wiring and piping for the control equipment are installed under the floor. is installed.

However, recent advances in electronic control equipment have been remarkable, and equipment needs to be replaced frequently. Underfloor wiring and piping equipment must also be changed each time. This created a need for the development of a new type of raised floor that would allow for higher access. Of course, some conventional raised floors have structures that allow for subfloor construction by opening the floorboards in the required areas, but conventional raised floors that allow the floorboards in the desired areas to be opened freely are floorboards. It had the disadvantage that it was easy to move around, and the load strength of the floor surface was not sufficient.

The present invention was developed in view of the above-mentioned drawbacks of conventional free access floors, and by devising a special connection relationship between level-adjustable floor posts, joists, crossbeams, and floorboards. It is possible to meet the modern demands as mentioned above, and
The technical challenge is to provide an ideal free access floor whose dimensions can be easily adjusted to suit the construction space on site.

[Means for solving problems]

The means adopted by the present inventor to solve the above problem will be explained below with reference to the accompanying drawings.

That is, in the present invention, the slabs are arranged in a row at a required interval on the slab S, and the surface level of the upper end support part 11 of the slab S is aligned to the same height by the operation of the adjusting bolt mechanisms 12 and 13. Floor post 1/1
The bottom surface is supported by the floor posts of each row and they are arranged in a parallel state, and the top surface thereof forms a stepped shape with a middle height, and the outermost edge has a support part 2.
1, 21, the joists 2, 2... having stepped portions 22a, 22b in the central part are horizontally fixed between the support portions 21, 21 of the adjacent joists 2, 2, and the lower portion 22a in the stepped portion is fixed. A means of horizontal joists 3, 3, which are continuous on the same level and form the lattice frame F by intersecting with the joists 2, 2, and; …It is removably laid on the top, and the step portions 22a and 2 of the joist 2 are provided on the back side of the joist 2.
The above-mentioned technical problem has been solved by employing a floorboard 4, 4... in which a cutout 41 having a shape matching 2b is formed, and the above-mentioned means have been skillfully linked. It provides a raised floor with a key point.

〔Example〕

Hereinafter, the present invention will be explained in more detail based on embodiments shown in the accompanying drawings.

The adjustment bolt mechanism of the floor post 1 used in Fig. 1 is composed of a stand sleeve 12 made of synthetic resin with a male thread formed on the inner circumferential surface and a bolt 13 made of synthetic resin that is screwed into the stand sleeve 12. ing. In this case, the use of synthetic resin material (for example, "nylon 6") as the material for the sleeve 12 and the bolt 13 is expected to have a cushioning effect.
This is because the room can be kept quiet. A rectangular wooden board is fixed to the upper end of the bolt 13 to form the upper end support part 11.

The floor posts 1 are arranged in a row on a concrete slab S at required intervals, and the upper end support part 11
are all aligned to the same height, and wooden joists 2, 2, etc. shaped in steps of medium and high heights are arranged and fixed in parallel on top of them. The outermost edges of this joist 2 on both sides serve as pedestals 21, 21, and the convex central portions serve as stepped portions 22a, 22b.

Yokosan 3, 3... are joists 2 arranged as above
They are horizontally fixed at predetermined intervals so as to form a lattice frame F between the adjacent support parts 21 and 21. This Yokogi 3
is made of wood, and its thickness is continuous with the lower part of the stepped part.

The floorboards 4, 4... are the stepped portions 2 of the joists 2 above.
In the illustrated example, a cutout portion 41 is formed on the back side edge of each floorboard 4, and stepped portions 22a and 22b of the joist are formed in grooves formed by the floorboards 41 and 41 therein. The structure is such that they fit together and stick together.

Although the specific examples of the raised access floor of the present invention are generally as described above, the present invention is by no means limited to the illustrated examples, and the scope of claims for utility model registration is
It goes without saying that various modifications can be made within the description given above, and in particular, various interlocking structures can be adopted regarding the connection relationship between the joists 2 and the floorboards.

[Effects of this invention]

As explained above, in this invention, the joists, crossbeams, and floorboards can be constructed of wood, making it easy to adjust the dimensions on site to suit the construction space. The strength has been greatly strengthened, and since there is a suction structure between the floorboard and the floorboard, there is no risk of it sliding around, and when replacing electronic equipment, wiring and piping under the floor can be easily removed. When alteration work becomes necessary, the floorboards can be easily opened at the necessary locations, significantly improving work efficiency, and can be said to have great practical value.
