Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is used in rooms where a large number of cables are exposed on the floor, such as computer rooms, telephone exchange rooms, and hospitals, where a double floor structure is used to hide the wiring. This article relates to the flooring method and equipment used.

When equipment such as computers is rearranged in a room that employs this kind of double floor structure, it is necessary to change the position of cables from the floor and some of the wiring.

In such cases, you can attach or detach only some of the floor panels as necessary.
Or, if you make it replaceable, the work will be easier.

Conventionally, a construction method that satisfies these requirements involves installing a large number of support legs at regular intervals vertically and horizontally on the subfloor surface, and placing a large number of floor panels on each support leg in sequence. However, according to this proposal, the positioning of each support leg with respect to the subfloor surface and the alignment of the floor panel with respect to the support leg are extremely troublesome, resulting in poor construction efficiency, and furthermore, the laying of the floor panels may be incorrect. It was easy to occur.

In addition, there was a risk that the support legs would fall due to vibration or impact, and the support state of the floor panel was unstable.

Therefore, in the present invention, we have developed a flooring method and device that is easy to install, has no irregularities, and has good stability in supporting the floor panels, on the premise that only a part of the floor panels can be attached or removed or replaced as needed. This is what we do.

A feature of the construction method of the present invention is that two first frame members, a plurality of second frame members, and a plurality of partition members are used to form a rectangular outer shape and a plurality of floor panels inside. A flooring construction method in which a required number of flooring units having fitting portions are assembled on a subfloor surface, and then a floor panel is removably fitted into each floor panel fitting portion of the flooring unit to construct a floor. The above No. 1. The second frame member and the partition member each have a stepped part on the upper part for engaging and supporting the floor panel, and a hole for wiring on the side surface, and the first frame member has a step part on the upper part for engaging and supporting the floor panel, and a hole for wiring on the side surface. The second frame member is provided with a recess, and the second frame member is provided with a partition member engagement recess on the side surface of the intermediate portion, and the two first frame members are installed parallel to each other on the subfloor surface, and each 2 frame members into both boxes 1
Each partition member is installed on the floor subfloor in a state in which the first frame member intersects perpendicularly between both ends and the middle part of the frame member and engages with the first frame member through the second frame member engagement recess at the intersection thereof, and each partition member is installed on the floor subfloor in a state that intersects perpendicularly with the second frame member between the intermediate portions of each of the second frame members and engages with the second frame member through the partition member engagement recess at the intersection thereof. It consists in assembling the flooring unit.

The device of the present invention is also characterized by two first frame members installed parallel to each other on the subfloor surface and the two boxes 1 and 1.
A plurality of second frame members installed on the floor subfloor so as to be orthogonal to the first frame member between both ends and the middle part of the frame members, and a plurality of second frame members that are orthogonal to the first frame member between the middle parts of the two container frame members. A required number of flooring units each having a rectangular outer shape and having a plurality of floor panel fitting portions inward, each consisting of a plurality of partition members that are grounded to the subfloor surface, and each floor of the flooring unit. It consists of a floor panel that is removably fitted into the panel fitting part, and the floor panel is detachably fitted into the panel fitting part. The second member and the partition member each have a stepped part for engaging and supporting a floor panel on the upper part and a hole for wiring on the side surface, and the first frame member has a second frame on both ends and on the side surface of the middle part. The second frame member is provided with an engagement recess into which the end of the member engages, and the second frame member is provided with an engagement recess on the side surface of the intermediate portion into which the end of the partition member engages.

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

Reference numeral A denotes a floor covering unit, which includes two first frame members 1.1, and a plurality of second frame members 2 installed orthogonally to the first frame members 1 between both ends and between the intermediate portions. . . . and the plurality of partition members 3 installed perpendicularly thereto between the container cylinder 2 frame member 2 . It is structured like a framework with 4...

Then, depending on the size of the room in which the flooring unit A is to be constructed, the required number of sets of flooring units A are arranged adjacent to each other.
It is laid on the subfloor surface while sharing the frame member 1 or the second frame member 2 at the end.

As shown in the figure, the basic type of unit A is constructed by two first frame members 1, 1, four second frame members 2..., and six partition members 3... The shape is square,
It is assembled in a form with nine floor panel fitting parts 4 in the shape of a base grid inside.

If it is not possible to use only the basic types listed above due to the shape and floor plan of the room, each member
, 2, 3 and the number of second frame members 2 and partition members 3 used are different from those of the basic type, and various irregular types of units having a rectangular outer shape are used.

However, in the present invention, a basic type having a rectangular outer shape may be used.

Further, the specific dimensions of the unit A are not particularly limited, and may be appropriately selected in consideration of transportation, construction, and other conveniences.

The members 1, 2, and 3 constituting the flooring unit A have the same height and thickness, and their common structure is that they all have a convex cross section, so that the periphery of the floor panel is formed on both the left and right sides of the upper part. A stepped portion 5 is formed to engage and support the portion.

The height dimension of the vertical surface 5a of this stepped portion 5 is smaller than the thickness dimension of the floor panel by a predetermined dimension.

In addition, as another common structure, each member 1, 2, 3
A hole 6 for wiring is also provided at the lower side of the central part in the length direction.

On the other hand, the first. As a common structure of the second frame members 1 and 2, engagement recesses 7..., 8 are provided on both left and right sides at two intermediate portions in the longitudinal direction.
...is formed.

Furthermore, as a unique structure of the first frame member 1, both ends in the length direction are formed into a planar convex shape, thereby forming recesses 7' on the side surfaces of the both ends.

These engaging recesses 7, 7'8 are formed below the horizontal surface 5b of the stepped portion 5 on both side surfaces of the members 1, 20, and have a depth slightly smaller than the thickness of the horizontal surface 5b.

In addition, the width dimensions of the engagement recesses 7 and 8 are the same as the thickness dimensions of the member 1°2.3, and the width dimensions of the engagement recesses 7 at both ends specific to the first frame member It is set to 1/2 of the recesses 7 and 8.

By the way, in the case of a unit installed at the edge of a room, or at the boundary between the lectern and the flat floor in a classroom, the first frame member 1 on one side or the second frame member 2 at the end has a floor panel attachment. It is sufficient that the step portion 5 for joint support is provided only on one side.

Therefore, for such an end unit, as shown in FIG. 4, a first frame member 1' or a second frame member 2, in which one side surface is formed flat over the entire length, is used.

Note that the material of each member 1, 2, and 3 is not particularly limited, and may be wood or metal such as steel or aluminum.

Using wood has great construction benefits, such as being able to cut and adjust the cutting on site.

B1 and B2 are floor panels, one panel B1 has a semi-rigid vinyl tile 10 fixed to the top surface of a panel main body 9 made of plywood or the like, and the other panel B2 has a carpet 11 fixed to the top surface of the same main body 9. Either one can be used as desired.

Or, as described later, both B1. It is also possible to use B2 in combination.

However, in the case of carpet type floor panel B2, the overall thickness is slightly thicker than that of semi-rigid vinyl tile type panel B1.
2 is used, the height of the vertical surface 5a of the stepped portion 5 of each member 1, 2, 3 shall be made higher by that amount. 3C is a joint fitted to the upper part of each member 1, 2, 3. Below the hard body part 12, which is made of hard plastic or metal such as stainless steel and has an inverted U-shape in cross section, there are soft skirt parts 13, 13 made of soft plastic or soft rubber.
are integrally molded or connected integrally using appropriate connecting means.

The height dimension of the main body portion 12 of this joint member C is as follows for each member 1,
The dimensions are such that it can cover about halfway up the vertical surface 5a of the stepped portion 5 from the upper end surfaces of the step portions 2 and 3.

Further, the height of the skirt portions 13, 13 is such that at least the portion extending from the lower half of the vertical surface 5a of the stepped portion to the horizontal surface 5b can be covered with sufficient margin while being bent and deformed along the shape of the stepped portion. Dimensions.

Next, the construction procedure will be explained.

After marking out a reference line indicating the start of flooring on the subfloor surface of the room where construction is to be performed, according to the layout drawing prepared in advance, assemble the first flooring unit A on the subfloor according to this reference line. .

There are no particular restrictions on the order of assembly of this unit A, but usually the first frame members 1, 1 are installed in parallel with a predetermined interval, and then the second frame member 1, 1 is installed between the first frame members 1, 1. Part 2...
, and finally the partition member 3... is assembled into the second frame member 2.
...to be installed in between.

At this time, both ends of the second frame member 2... are connected to the first frame member 1.
, 1 into the engagement recesses 7, 7' of the partition members 3...
Both end portions of ・ are engaged with the engagement recesses 8 of the second frame member 2 .

By doing this, the members 1, 2, and 3 are assembled in a state perpendicular or parallel to each other, and are positioned and spaced from each other at a predetermined distance, so that each part of the flooring unit A can be assembled accurately to the predetermined dimensions. and can be configured quickly.

In this assembled state, the floor panel fitting part 4 of a certain size is
. . . is surrounded by the step portions 5 . . . of the respective pieces 1, 2, 3.

Note that this flooring unit A may or may not be fixed to the flooring substructure, and if fixed, it may be fixed using plate pieces (not shown) placed between members 1 or 2 at key points. ) can be fixed to the subfloor using concrete nails, etc.

Alternatively, if the flooring must not be damaged, such as when laying a floor over an existing floor in a rental building, etc., insert gaps between the members to improve the shape retention of unit A itself. Good too.

Thereafter, in the same manner, the required number of flooring units A...
Adjacent units are assembled on a subfloor in a state in which they share the first frame part 1 or the second frame member 2 at the end.

In this case, as described above, in the end unit A,
For example, a frame member 1' or 2' with one side flat is used for the portion in contact with the side wall E.

Thereafter, joint members C... are attached to the upper parts of each member 1, 2, 3 in each unit A.

In addition, in the meshing portions of the engaging recesses 7, 7, and 8 of the respective members 1, 2, and 3, the skirt portions 13 of the intersecting joint members C2C are cut away in a range corresponding to the meshing portions.

Thereafter, the floor panels B... or B2... are fitted into the floor panel fitting portions 4... of each floor covering unit A and laid.

In this case, the four peripheral parts of each floor panel B1 or B2 are engaged and supported by the stepped parts 5 through the joint members C, so that the upper surface thereof is connected to the upper end surface of the joint member C. In a state where it is flush and automatically positioned in front, back, left and right,
It is laid out in an orderly manner, matching the top surface, length, and width.

In addition, by this pulse fitting, the skirt part 13 of the joint member C is bent along the step part 13 and the step part 5 is bent.
and the floor panel B1 or B2.

By the way, wiring to devices such as computers is performed using the wiring holes 6 of each unit A in the step before laying the floor panel.

The floor panel B1 or B2 used at the location where this equipment will be installed has holes (
(not shown).

According to this pre-dawn construction method, it is only necessary to fit the floor panels B1... or B2 into the panel fitting parts 4... of the floor covering unit A, and there is no need for troublesome panel positioning at all. Because of this, the work of laying floor panels becomes very easy and there is no risk of misalignment.

In addition, each flooring unit A is basically made up of three types of members 1
, 2, 3 only, and this member 1, 2,
3 can be easily combined using the engaging recesses 7, 7', 8, and once the reference position for starting tensioning is accurately determined, all that is left to do is to mechanically combine the members 1, 2, and 3. Since there is no need for troublesome positioning, assembly of unit A is also extremely simple.

Therefore, the construction rate is very good.

In addition, unlike conventional floor panels that are supported by support legs, the floor panel B1 or B2 is supported by a framework-like flooring unit A that has no risk of falling over, so the stability of the floor panel support is extremely high. becomes.

Furthermore, in this embodiment, the floor panel B1 or B2
Since the peripheral part of the joint member C is supported by the stepped horizontal surface 5b via the soft skirt part 13, the skirt part 13 provides a buffering effect and absorbs vibrations during walking to prevent floor noise. can do.

According to this joint member C, even if the depth of the stepped portion 5 is slightly changed depending on whether a semi-rigid vinyl type floor panel B1 or a carpet type floor panel B2 is used, Dimensional differences can be sufficiently absorbed by the soft skirt portion 13.

By the way, when it becomes necessary to change the cable pull-out position from under the floor or some wiring due to rearrangement of equipment, etc., it is possible to freely remove only the necessary part of the floor panel B1 or B2 with a suction cup or the like. It is a matter of literature that panels with and without holes for cable extraction can be interchanged.

Moreover, in this case, since the floor panels B1... or B2... are individually and independently fitted into the floor panel fitting portions 4..., the panels stick together after construction and are difficult to remove. There is no risk of this happening, and the panel can be easily attached, detached, and replaced.

Note that, as shown in FIG. 11, it is also possible to install a unit A using a semi-rigid vinyl type floor panel B1 and a unit A using a carpet type floor panel B2 adjacent to each other.

In this case, for example, in the first frame member 1 commonly used by both units A, A, the stepped portions 5, 5 on both sides may be formed at different levels.

In addition, the height of each member 1, 2゜3, that is, the height of the flooring unit A, can be selected as appropriate depending on the application, and in some cases, two types of flooring units with different heights may be used. They may be installed adjacent to each other.

As described above, according to the present invention, it is possible to fully achieve the basic purpose of being able to freely attach or detach or replace only a part of the floor panels as needed, and in addition, construction is extremely simple, reducing construction costs and construction time. In addition to being able to shorten the time, there is no risk of misalignment in laying the floor panels, and in addition, it is possible to obtain a double-layered floor with good stability in the floor panel support state and excellent durability. be.

Furthermore, since the flooring unit is basically constructed of only three types of members, it is convenient in manufacturing, stocking, and other aspects of the unit, and is extremely useful in practice.
