Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a double floor structure capable of wiring to a floor surface and a method of constructing the same.

[0002]

2. Description of the Related Art In recent years, office automation equipment has been widely used in offices due to its diversification. For this reason, the necessity of floor wiring management has been increasing, and the use of double floor panels has been expected to respond to this, and has been widely used.

Recently, double-floor panels have been diversified and can be easily renewed.
There is an increasing demand for double floor panels that are lightweight, can be easily constructed by anyone, are well adapted to any uneven floor surface, and have little backlash.

In particular, wiring groove type panels are widely used, and this type of panel is disclosed, for example, in Japanese Patent Application Laid-Open No. 62-2848.
As described in No. 54, since this is composed of a wiring groove forming block made of a molded resin sheet and concrete, it has a load-bearing property and is heavy, so there is no fear of misalignment, There is an advantage that panels can be abutted and laid, and further, the flexibility of the resin sheet portion can follow irregularities on the floor without irregularity adjustment.

However, since it is made of a composite material of resin and concrete, the weight is heavy, and a large number of different wiring covers such as a center cover and a straight cover are required. Also, there is a problem that it takes time to carry in and out at the time of construction.

On the other hand, there is a panel integrated with support legs.
This type of panel forms a unit panel by connecting a plurality of support legs at a connecting portion, and lays the panel on the support legs by fitting or the like to form a double floor.

In this type of panel structure, for example,
Japanese Patent Application Laid-Open Nos. 0-164537, 4-124366, 5-28834, and the like.

[0008] In the support leg integrated type panel, a plurality of support legs are laid and there is no connection structure at the time of laying work, so that a position shift or the like occurs, and the panel laid on the support leg upper surface secures strength. Therefore, since it is made of a steel plate and is thick, large, and heavy, it takes time and effort to perform the work, and there is a problem that the workability is deteriorated.

Moreover, since the panel is large, there is a problem that even if the support leg side follows the ground and absorbs, the panel cannot be adjusted to the ground because of the large size of the panel. However, there is a problem that rattling occurs during walking.

In order to eliminate the rattling, there is a fixing means by fixing fasteners or the like, or a fitting fixing means for forcibly fitting the column and the panel to each other and firmly connecting them. In this case, the number of parts increases, and there is a problem in the reliability of the fixing force.Even if the fitting is strengthened, there is a gap between the strut and the floor due to unevenness, so that the bottom of the strut is floored when walking. The problem of rattling by hitting the surface remains.

On the other hand, in the panel connection structure, there is, for example, Japanese Utility Model Laid-Open No. 6-85845. Among them, the one to be engaged and connected is formed by using an engagement structure completely different from the panel support portion or the leg portion. In addition, because of the configuration of connecting with a small gap between the supporting parts or legs, the structure is complicated, it is difficult to attach and detach, the workability of connecting laying is poor, and the supporting parts or legs are very close to each other Therefore, there has been a problem that the ability to follow the ground and absorbability are poor.

Further, in a connection structure comprising a ring body and a support portion fitted thereto, for example, in Japanese Patent Application Laid-Open No. 6-322947, the connection work is performed by fitting the ring body from above the height of the support portion. Have to work on
There is a problem that connecting construction is troublesome.

[0013]

As described above, conventionally, in any of the above-mentioned double floor structures and their construction methods, the construction is relatively simple and the construction is easy. There is no floor panel structure or double floor that can follow or absorb unevenness on the floor surface, is well-adapted, and has little backlash, which has a satisfactory combination of both.

In this kind of industry, market, and technical field, construction is easy with a simple structure, and even with such uneven floor surface, the construction can be easily carried out without lay-off adjustment by laying down. Therefore, there has been a long-felt need for a floor panel structure that does not rattle even when walking on a floor surface and a method of constructing the floor panel.

In the above-mentioned conventional example, a double floor for wiring is described as an example. However, the present invention is not limited to this. is there.

The present invention has been made in view of the above-mentioned conventional problems, and an object of the present invention is to provide a floor panel system which can be easily laid and constructed, and which can sufficiently deal with uneven floor surfaces. An object of the present invention is to provide a floor panel structure capable of following or absorbing and suppressing rattling, and a method of constructing the floor panel structure.

In the description of this embodiment, the double-floor unit panel body 1 is shown as an example in FIGS. 1A and 1B, but is not limited thereto. For example, as shown in FIG. , The first support 10 and the second support 1 in FIG.
The positions 5 and 50 may be interchanged, and the other positions are optional.

In this case, the first support portion 10 and the connecting portion 40 extending from the first support portion 10 are located only on the side, and the second support portions 15 and 50 are Since it is no longer extended, it becomes easy to apply the border material in, for example, wall-side treatment.

The floor plate 30 is formed in a substantially rectangular shape as shown in FIG. 1, and its squares (four corners) are respectively supported on the upper surface of the first support part 10, and the center part is supported by the second support part 15. Have been. The squares of the floor plate 30 are fitted into the slits 16 provided in the first support portion 10, and alignment is performed. The width of the slit 16 is at least twice the thickness of the floor plate 30. If floor plates 30 of the same shape are placed adjacent to each other, a double floor panel structure is completed.

FIG. 2A is an enlarged perspective view of the first support portion 10, and FIG. 2B is a bottom view thereof.

The first support portion 10 has a groove 11 which is formed to be connected to the slit 16 and serves as a guide for the support portion separation position. Notch 1 in at least one of them
8 is formed, and a cutter or the like is applied to the cut portion 18 so that the support portion 10 can be separated by the action of a vertical force. The support portion 10 includes four hollow blocks at four corners, each of which has an upper surface 14 and a side surface 15.
And the inner wall 13 has a cylindrical shape.

In the illustrated embodiment, the notch 18 is provided at a position outside and below the support portion 10 and on the upper surface side. However, the cut portion 18 may be provided only at the outside or only at the inside. However, other than that, a single or a combination of a plurality of them is also possible.

FIGS. 8A, 8B, and 8C show FIGS.
4B, the above four blocks are schematically shown by oblique hatching. In FIGS. 3A and 3B, the upper diagram shows a plan view and the lower diagram shows a side view. . The first support portion 10 is provided with a groove portion 16 into which the side end portion 36 or the rib 38 of the floor plate 30 shown in FIG. 3 fits, and a cut portion 18 which can be separated by cutting the support portion 10. .

The cut portion 18 is formed on the basis of the position of the groove 11 as shown in FIG. 8A, outside the support portion, in FIG. 8B, inside the support portion, and in FIG. on the inside,
Each is provided.

As a result, the outer side (below) of the support portion 10,
By providing the plurality of cut portions 18 on at least one of the inner side and the upper surface side, for example, simply by the action of a force for applying a cutting tool such as a cutter or a nata to the cut portion 18 and cutting in the vertical direction, it is easy. It can be cut off, and a storage space for wiring equipment and the like can be easily formed.

The circular hole 19 at the center of the upper surface 14 of the support portion shown in the figure is used to form a storage space for wiring equipment and the like, when the upper surface of the support portion needs to be cut in 1/4 area.
It is formed in order to prevent the cut by the cut from extending to another 3/4 area.

For example, if a blade having a width larger than the width of the support portion is used, at least one of the outer side, the inner side, and the upper side is used.
The support portions can be easily cut off alone or simultaneously at a time by the action of a force to cut or punch out the two cut portions 18 in the vertical direction, and the construction is easy.

The hole 12 is used for positioning and fixing the floor plate by fitting with a convex portion of the floor plate described later. The slit 16 is where the rib 38 of the floor plate 30 described later fits, and the rib 38 of the adjacent floor plate fits adjacently.

The unit thus formed has the following features. (1) The unit bodies can be easily constructed by mutual connection between the connecting portion 40 and the second support portion 50. (2) The supporting parts 10 and 15 are formed to have different diameters, are arranged at equal intervals in the connecting part, and
Even at the mutual connection between the support 0 and the support portion 50, the positions are uniformly maintained at equal intervals, so that it is possible to follow unevenness of the floor surface.

The floor plate 30 is constructed such that a plurality of unit bodies 1 are connected and laid on the floor surface and then laid so as to be supported by the first support portion 10 and the second support portion 15. The unit body 1 having substantially four sides is divided into a plurality of sections so as to have the same area, and is formed into a substantially square shape having the same shape.

Then, the floor plate 30 is moved to the first,
When the floor plate 30 is placed on the second support portions 10 and 15, the floor plate 30 is supported in the first support portion 10 by being fitted in a substantially cross-shaped groove at substantially a corner at substantially a quarter of each area. And
The second support portion 15 is surface-supported substantially in the vicinity of the center, and a plurality of the support portions can be laid in a line on each support portion.

Next, a construction method will be described.

The unit body 1 shown in FIG. 1 is connected by a plurality of connecting portions 40 and an adjacent second supporting portion 50,
When a large number are uniformly laid on the floor surface, the first and second support portions 10 and 1 are connected by the connection portion 40 as shown in FIG.
5 are formed at regular intervals at regular intervals so that the floor plates 30 can be aligned.

As a result, the connecting portions of the unit bodies are not visually noticeable, and the unit bodies 1 can be laid uniformly.

The connecting portion 40 allows the connecting body 1 to be laid and positioned and fixed reliably and easily. Further, since the floor plate 30 has the same shape and the same fitting structure, it is easy to lay the unit on the supporting portion.

The unit body 1 preferably has a size of about 450, based on the size of the tile carpet as the floor covering.
mm to 600 mm square, and the plate 30
For example, the size of the carpet is preferably about 1/6 to 1/3. The unit body is divided into a plurality of sections to form a substantially square shape, about 100 mm to 200 mm square TYP1
65mm, thickness about 1.0tmm ~ 2.5tmmTYP
Since it is formed of a 2.3t thin steel plate panel, even if the plate 30 is laid, the unit body 1 can follow the uneven ground.

In particular, since it is divided into a plurality of squares, irregularities can be well absorbed, and it is easy to adjust to irregularities.

Note that the unit body 1 is formed by the connecting portion and the connecting portion.
Can be integrally formed with a minimum amount of resin, and the above-mentioned thin steel plate 30 can be used, so that it is lightweight, and is easy to transport and lay.

The substantially rectangular steel plate 30 is formed such that the upper surface of the first support portion 10 has an area of 上面 of the upper surface and the corner portion has the second support portion 15.
Since the substantially central portion is supported by the area of the upper surface, the required and sufficient load resistance as a double floor can be obtained.

Since the unit body 1 is molded from an integrally molded material, manufacture and design are easy, and since the unit body 1 is constituted only by the plate 30 having a common shape, the number of parts and materials are small, and Possible, first and second
A thin steel plate can be applied by the arrangement of the plurality of support portions 10 and 15, and the cheapest plate material can be used. Since it is lightweight, there are various effects such as no need for transportation equipment and no labor.

The cushioning material 20 is provided on the upper surface of the support 10 shown in FIG.
And a square 36 of the plate 30 as shown in FIG.
By adopting a structure in which the projection 32 provided on the support member 10 is fitted into the hole 12 of the support body 10 from above, easiness of construction and rattling due to following the ground are prevented. It is formed by fitting the side end 36 of the floor plate 30 to the slit 16 of the support portion 10.

As shown in FIG. 2, a through hole 12 is formed on the upper surface of the support portion 10 such as a support leg or a pedestal.
The hole 12 is provided with a cushioning member 20 for reducing a walking sound generated when walking on the floor plate. The figure shows a partially cut-out state of the cushioning member 20.

The cushioning member 20 is an elastic member having a cushioning property. In short, any material can be used as long as it can reduce walking sound. For example, as a vibration damping material and a sound absorbing material, there are a sheet-like resin, a foam, a rubber, a nonwoven fabric and the like (thickness of about 0.5 mm to 2.5 mm). Slit 16
A cut is provided on the cushioning member 20 corresponding to the position.

At the time of construction, when the floor plate 30 is laid, the convex portion 32 of the plate fits into the hole 12 via the buffer member 20, and the floor plate can be positioned and fixed on the support portion.

The penetrating hole 12 formed on the upper surface of the support portion 10 has a tapered or R-shaped portion (a shape whose width increases downward) 11 at the periphery as shown in the figure. While the plate convex portion 32 is received by the tapered or rounded surface via the buffer member 20, the fitting operation is promoted, and the plate is securely positioned and fixed.

The plate projection 32 may be any projection as long as it fits into the hole 12, and may be formed by embossing or punching as shown in the drawing, and may have any structure as long as it can be positioned and fixed by fitting.

Next, the support portion 1 with the buffer member 20 interposed
A description will be given of the operation of fitting the 0 hole 12 and the projection 32 of the plate.

A cushioning material 20 is provided on the upper surface of the support portion 10 by sticking so as to cover the through-hole portion 12. When the plate 30 is laid on the support portion, a plate convex portion 32 is formed from above the buffer member. Pressed.

At this time, the side end portion 36 of the plate is fitted in the substantially cross-shaped groove 16 for mounting formed on the upper surface of the support portion, and the plate convex portion 32 causes the cushioning material 20 to form the convex shape. And press down to fit in the hole 12. The convex part 32
Is substantially supported by the elastic force of the cushioning material 20 itself pushed down since the hole 12 is penetrated, and the peripheral edge, the taper or the R portion 11 of the hole 12. Thereby, a rattling buffer effect can be obtained.

In this way, at the time of walking or when a load is applied to the upper surface of the plate, even if there is unevenness, at least one projection 32 at the end of the plate is securely fitted into the hole 12 via the buffer member 20. The plate 30 can be reliably positioned and fixed, and the construction is facilitated.

Even if the convex portion 32 at the other end of the plate does not fit into the hole portion 12 and runs up due to the unevenness, the plate 30 can be held by penetrating into the peripheral edge 11 of the hole portion 12 through the buffer member 20. Even if the user walks in a state where there is unevenness on the floor, the unevenness can be absorbed and the plate 30 can be reliably held, and the generation of rattling noise can be reduced to a minimum.

At least the tip of the cushioning material 20 is brought into contact with the side surface of the plate 30 laid on the support portion 10,
Alternatively, the buffer member 20 for reducing the walking sound is provided in the groove 16 formed on the upper surface of the support portion 10 according to the structure in which the support member 10 is pinched.

When the floor plate 30 is laid, the plate ends 36 at the four corners are fitted into the grooves 16 of the support portion 10 and the tip of the cushioning member 20 (notches 2 to be described later).
1) is a side surface of the plate end portion 36 (the rib 38).
, Or at least both side surfaces of the end thereof, and the floor plate 30 is held on the support in this state.

The holding of the floor plate 30 is performed by the cushioning member 20 as shown in FIG.
Therefore, it is possible to suppress the sound of walking sounds during walking, particularly high-frequency components that are easily perceived by human ears.

The cushioning material contacts and holds the side edge of the plate just by fitting the floor panel into the groove on the upper surface of the support portion as in the past, so that a walking sound buffering effect can be obtained. Construction is easy because it is only necessary to fit the groove.

At the time of walking or when a load is applied to the upper surface of the plate, at least one end of the plate is fitted into the groove, and the groove is brought into contact with the buffer at least with the end of the plate. The plate can be held on the legs, thereby reliably reducing rattling of the plate even if the floor surface is uneven.

As shown in the figure, the buffer member 20 may be formed of a sheet having a notch 21 at a groove position where the plate end 36 fits so as to be easily provided on the upper surface of the support portion 10.

In this case, since the cushioning member is in the form of a sheet, it is easy to install and fix it on the upper surface of the support portion with an adhesive or an adhesive, and the amount of the cushioning member can be reduced, so that the cost can be reduced. In addition, the shape and size are arbitrary and only the cut 21 is provided so that the side of the plate can be installed in the groove of the support portion.

If at least one plate projection 32 fits into the hole 12 of the support 10 via the cushioning material 20,
Even if it floats to some extent due to inconvenience, the protrusion 32 contacts the cushioning material 20 so that it can be held. Even if the other protrusions 32 are not securely fitted in the holes 12, the protrusions 32 can bite into the cushioning material 20. If the plate side end 36 is in contact with and holds the cushioning material 20 in a supplementary manner, delicate irregularities can be absorbed and rattling can be reliably prevented.

Further, even if the convex portion 32 is not fitted in the hole portion 12 and runs up due to a large unevenness, the plate side end portion 36 can be securely clamped by the cushioning material 20. Also, the reverberation sound of the plate 30 is reduced, and the rattling sound can be minimized.

In the following, a column of the unit body 1 composed of the supporting portions 10 and 15, the connecting portion 5, the connecting portions 40 and 50, and the cutout portion 18 formed so as to be connected to the slit 16 that can be cut. The unit combination construction method in part cut is described.

A plurality of support portions 10 are arranged at regular intervals so as to form approximately four sides, and are connected to each other by a connection portion 5.

The connecting portion includes the supporting portion 10 on at least one side or the first connecting portion 40 provided outside the connecting portion 5 and the supporting portion 1 on the other at least two sides.
0 or a second connecting portion 5 provided outside the connecting portion 5
0 and

The cutting portion 18 is formed with a cut into which a tip of a cutter or the like is inserted at an arbitrary position of the support portion or the coupling portion so that the cutting portion 18 can be cut into a predetermined shape and size.

The unit body 1 is based on
A plurality of them are connected by the first and second connecting portions 40 and 50, and a plurality of them are laid in a plane and constructed as follows.

First, in the first construction step, the unit body 1 is cut off by the cutting section 18 according to a predetermined rule to form a plurality of divided unit bodies divided into a predetermined size. For example, as shown in FIG.
2, a3, and a4, and as shown in FIG.
1, b2, b3, and b4, and divided into c1, c2, c3, and c4 as shown in FIG. 5C, or d1, d2, and d3 as shown in FIG. 5D. Can be.
In these divided unit bodies, for example, the unit body 1 is divided into four parts in a cross, four parts in a side, three parts in an L shape, and three parts in a side, and corners are cut off, and a predetermined rule as shown in FIG. Is formed according to the excision.

Next, in the second construction step, each of the divided unit bodies is connected to the first and second connecting portions 40 and 50.
The first connecting portion 40 and the second connecting portion 50 are positioned so as not to be located outside the support portion 10 or the connecting portion 5.
Are connected to each other to form a connected unit body having a form different from that of the unit body 1.

First, in the case of FIG. 5A, each of the divided unit bodies a1, a2, a3, and a4 cut in a cross shape is rotated by 180 degrees, and the connecting portion 40 and the second supporting portion are mutually connected. And 50 to form a connection unit as shown in FIG. 6 (a).

Next, in the case of FIG. 5 (b), the divided unit bodies b1, b2, b3, b4 divided into three in the horizontal direction and cut.
Are connected to each other in the lateral direction and are connected to each other. First, b2 and b
3 is connected in the lateral direction, and then, b1 and b4 are connected to face each other, and further connected to b3 in the horizontal direction. Thus, a horizontally long connecting unit body is formed as shown in FIG. In this case, it can be effectively used in the residual space for one sheet of the floor plate 30 and the wall edge processing.

In the case of FIG. 5C, each of the divided unit bodies c1, c2, c3, and c4 whose right side and lower side are cut is connected at a position symmetrical with the cut position. The connecting portion 40 and the second supporting portion 50 first connect c1 and c2 on the left side, then connect c1 and c3 on one side, and place the remaining remaining c4 at the upper left position in the drawing. A connecting unit body is formed as shown in FIG. 6 (c). This is basically the same shape as the connecting unit body of FIG.

Further, in the case of FIG. 5 (d), each of the divided unit bodies d1, d2, and d3 whose upper and lower and four corners are cut is connected to both sides of d1 by the connecting portion 40 and the second supporting portion 50. Are connected by d2 and d3, and the remaining four corners are formed without connection, and form a rectangular connection unit body as shown in FIG. 6 (d).

According to such a construction method, a plurality of the connection unit bodies are laid uniformly on the floor surface to form a floor panel structure.

Here, after the second construction step, a third construction step will be further added below.

In the third construction step, a plurality of floor plates 30 are uniformly laid on each of the connecting units so as to be supported by the first and second supporting units 10 and 15. Forming the floor panel structure.

FIG. 5 (a) is a perspective view of the supporting portion 10 shown in FIG.
6 (a), 6 (c), and 6 (d), according to an arbitrary resection method of the resection unit 18 according to a predetermined rule.
As shown in (b), (c), and (d), it is possible to obtain each divided unit body having a different form and area from the unit body 1 and in which the first and second connecting portions 40 and 50 do not extend. .

Thus, it can be butt-connected to another floor panel, for example, a border panel for wall-side construction, and can be continuously laid and constructed, thereby facilitating wall-side treatment.

Further, since the area can be changed, the construction can be performed according to the laying area and the remaining area near the wall.

Further, the connecting portion 5 for connecting the side portions of the support portions 10 is flexible so as to be adapted to the unevenness of the floor surface, or has a structure to absorb the unevenness of the floor surface. Followability can be maintained as it is.

In this embodiment, only four cutting methods are shown. However, the present invention is not limited to these four cutting methods. For example, a cutting method following a notched portion around a pillar, various other cutting methods, and the like. There are connection methods.

In the figure showing the shape of the floor plate, the floor plate 30 has a side wall 34 on at least one side to improve the strength, and also makes it easy to attach and detach the floor plate 30 to and from the support portion 10. A cut-out portion 38 is formed in at least one corner portion 36 by cutting out a side wall of a portion fitted into the groove portion 16. The height of the side wall due to the cutout portion 38 may be such that the support portion can be easily and stably fitted to and removed from the groove portion 16.
/ 2 is preferred.

First, when the side wall 34 of the floor plate is made of, for example, a steel plate, it is formed by bending to improve the load resistance of the plate 30, but a notch 38 leaves a small side wall. Therefore, the load-bearing strength can be maintained.

Second, the support 10 fitted in the groove 16
When the floor plate 30 is attached to and detached from, the corners of the floor plate do not bite into the groove, the force of fitting to and detaching from the groove 16 can be adjusted, the attachment and detachment can be easily performed, and wiring processing at the time of transfer and extension, etc. Construction becomes easier.

In the fitting structure between the support and the floor plate, when the floor plate 30 is laid in the hole 12 (or the protrusion 14) formed on the upper surface of the support 10, the protrusion 32 (or the plate) of the plate is formed. When the plurality of floor plates are positioned and fixed on the support portion by fitting the hole portion 34) into the hole portion 12 (or the convex portion 14), the adjacent floor plate 3
By forming a gap between zero, the position of the convex portion and the hole portion is such that it can follow a predetermined floor unevenness and is formed at an interval at which adjacent floor plates 30 do not contact at least. Is set.

Thus, the floor plate is supported on the supporting portion,
When easily positioned and fixed by the holes and the projections, the gap can prevent adjacent plates from contacting or hitting each other even when the floor is uneven, when walking or when passing through furniture.

Further, the floor plate is divided and subdivided into a substantially square shape, and the plate side portion 34 is restricted in its bending height so that the plate 3 can be made uneven.
Even if 0 is used, they do not collide with each other and rattle is suppressed.

In the side view showing the unit body 1 and the floor plate 30, in the case where the wall is processed, as shown, the first connecting portion 40 and the second connecting portion 50 may come to the border panel side, respectively. is there.

At this time, the floor plate 30 is
By bridging between the zero and the border panel 60, it is possible to fill the remaining space near the wall, but since the second connecting portion 50 is the same height as the second supporting portion 15 as shown in the drawing, Although the construction can be performed without any problem, the first connecting portion 40 cannot support the substantially center of the rear surface of the plate 30 because the height is low, resulting in insufficient strength.

To prevent this, the third support portion 45 is inserted into the first connection portion 40 so as to be at the same height as the second support portion 15 and the second connection portion 50, and the second connection portion 50
It is formed so as to be in the same state as described above. Thereby, similarly to the connection of the unit bodies, it can be easily constructed by insertion in the vertical direction.

[0101]

The double-floor structure and the method of construction according to the present invention have an effect of being easy to construct, being able to follow the ground, and suppressing rattling.

Regarding the workability, a notch was formed in the corner of the floor plate to reduce the amount of protrusion that fits into the support from the side, so that the fitting between the support and the corner of the plate was properly set and the plate was laid. Attachment / detachment at the time becomes easy.

The fitting and fitting of the plate projections and the holes of the support portions make it possible to reliably and easily position and fix the plate.

The laying work can be easily performed by connecting the units in the vertical direction of the connecting portion.

It is easy to cut off the pillars by the action of vertical force, and it is easy to divide the panels by cutting and combine them at the joints to form different types of divided units.

Regarding the non-trackability (prevention of rattling),
In the fitting between the support and the plate, a buffer material is interposed to fit the plate protrusion and the hole of the support, so that rattling can be suppressed and walking noise can be reduced.
