Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a floor structure in which signal lines, power lines, etc. for computers, etc. can be easily installed and their positions can be easily changed.

<Prior Art> The use of electronic office equipment is increasing not only in computer rooms but also in general offices, and the amount of wires connecting the equipment is also increasing.

For this purpose, we would like to use the space under the floor, but with the conventional structure where tiles are pasted directly onto the concrete floor, it is not possible to use the space under the floor.

Furthermore, even if the floor surface is raised and a space is created beneath it, it will be difficult to change or take out the wiring unless the floorboards are structured so that they can be easily opened and closed.

For this purpose, a construction method has been developed in which four adjustable legs are provided protruding from the bottom of each board, and a large number of these boards are arranged independently on a floor slab.

<Problems with the conventional technology> When a large number of plates with the above configuration are arranged on a slab, the height of the bottom legs of the plates must be adjusted one by one, which requires a large amount of work. was enormous.

Furthermore, when adjusting the height of one leg, the height of the adjacent plate would be out of alignment, and the adjustment range would expand one after another, which required a lot of effort.

Furthermore, if the structure is such that a board is attached to the top end of the adjustment foot, the bottom surface of the floor plate cannot be lower than the height of the adjustment foot, so the height for wiring does not need to be that large, but the presence of the foot This had the disadvantage that the space was unnecessarily raised, and the space above the floor, which was the most important place to live, became narrower.

<Object of the present invention> The present invention was made to improve the conventional drawbacks, and an object of the present invention is to provide the following floor structure.

(A) A floor structure that allows you to easily open and close the floorboards to install and change the arrangement of wires under the floor. (B) Only the necessary spacing for wiring can be secured under the floor, eliminating unnecessary height. Floor structure that does not sacrifice living space <C> A floor structure that allows the height of the floorboards to be adjusted while the floorboards are set.

<Examples> Examples will be described below with reference to the drawings.

<A> Adjustable legs FIG. 1 shows a perspective view of the adjustable leg A.

The adjusting leg A is composed of a horizontal receiving plate 1 and a bolt 4 screwed into the center of the receiving plate 1.

The bolt 4 has a groove 2 for rotational operation carved in its upper end, and a bottom plate 3 attached to its lower end.

In addition, since the groove 2 functions to connect the upper part of the bolt 2 and the tool and transmit rotational force,
It is not limited to the groove 2.

<B> Joist As shown in Figure 2, the joist B is made of steel, its cross section is oriented in the vertical direction, the webs 5, 5 are positioned facing each other, and the upper parts of the webs 5, 5 are connected by a plane. In addition to creating a space that is open from the bottom inside,
Horizontal flanges 6, 6 are formed outward from the bottom of each web 5, 5.

The depth of the space formed inside the joist B is approximately equal to the height of the webs 5, 5.

Furthermore, a plurality of operating holes 7 for inserting tools are formed along the longitudinal direction of the plane connecting the upper parts of the webs 5,5.

The height of the joist B is adjusted by rotating the bolt 4 by fitting the tip of a tool such as a screwdriver inserted through the operation hole 7 into the groove 2 at the upper end of the bolt 4.

<C> Floor Board The floor board C can be made of conventional concrete, wood, one with a heating function or air conditioning function, or other known materials.

The thickness of this floor board C is the same as the web 5 of the joist B mentioned above.
The height should be approximately equal to the height of the

<Construction Order> Next, the construction order using the above members will be explained.

<A> Arrangement of adjustment legs A plurality of adjustment legs A are arranged linearly on the concrete floor slab 8 at appropriate intervals.

The slab 8 is supposed to be finished flat, but since it is made of concrete, local unevenness cannot be avoided.

Therefore, leveling was carried out when arranging adjustment leg A.
The approximate height of the receiving plate 1 is adjusted by rotating the bolts 4 so that the surface of the floor plate C to be laid last forms a horizontal surface that maintains the designed height.

<B> Erection of joists Erection of long joists B on top of the plurality of adjustable legs A.

The joist B is installed with the flange 6 of the joist B placed on the upper surface of the horizontal receiving plate 1 of the adjusting leg A.

Since an upward space is formed between both flanges 6, the bolt 4 of the adjusting leg A is housed inside this space.

<C> Laying of floorboards Floor board C is laid between joists B and joists B.

In that case, the floorboard C will be mounted on the flange 6 of the joist B.

Then, the upper surface of the joists B and the upper surface of the floorboard C form a continuous and identical plane.

In order to be able to drop the floorboard C tightly between the joists B, the joists B and joists B are placed parallel to each other.
The spacing is determined by the width of the floorboard C to be used.

In that case, there is a method to arrange the intervals between all the joists B equally, but it is not possible to arrange them all at equal intervals,
It is also possible to adopt a method in which portions are configured at narrow intervals.

Then, even after placing desks and office equipment on top of the narrow floorboard, it is possible to easily open and close the floorboard in that narrow area without affecting the equipment as much as when lifting a wide floorboard.

<D> Fine adjustment After laying the floorboard C, inspect the entire surface again and adjust the plane if necessary.

In this case, since the operation hole 7 is opened on the upper surface of the joist B, the receiving plate 1 is raised and lowered by applying rotational force to the operation groove 2 of the bolt 4 from there, and the overall plane can be easily adjusted. can be done.

<E> Wiring Wire the computer, etc. in the space between the slab 8 and the bottom surface of the floorboard C.

Particularly in areas where the joists B are arranged at narrow intervals, when the floorboards C are opened and closed, there is little impact on surrounding desks and equipment.

Therefore, if the area between the joists B is used as the main line of the wiring group, subsequent changes and maintenance of the wiring will be extremely easy.

<Effects of the Present Invention> Since the present invention employs the above configuration, the following effects can be expected.

<B> The height of the receiving plate can be adjusted arbitrarily by rotating the bolt using a tool inserted into the hole on the top surface of the joist.

Therefore, fine adjustment of the height of a plurality of floorboards can be performed at once while the floorboards are set.

<B> The space formed inside the joist that accommodates the upper part of the bolt absorbs the amount of the bolt protruding from the upper surface of the receiving plate, which changes when the height of the floor plate is adjusted, so that there is no space between the floor plate and the floor slab. The wiring space to be formed can be set to the minimum necessary height that is less than the full length of the bolt.
