Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a double floor in which a space for wiring and storing telephone lines, computer cables and the like is formed on the floor of a building.
[0002]
[Prior art]
Conventionally, in order to realize under-floor wiring in an office, a double floor in which a space for storing and wiring telephone lines and computer cables on a floor surface of a building is often used. As a construction method of such a double floor, for example, a rectangular base having a plurality of supports connected to each other is laid on the floor surface of a building, and a panel is laid on the support of these bases. A method of laying a decorative floor material such as a carpet on a panel is known.
[0003]
In such a double floor, when a person walks on the panel, that is, on the floor, or moves furniture such as a desk or various office automation equipment, the panel causes a lateral shift with respect to the base, and the floor Since the surface may become unstable, the panel is often fixed to the base support.
[0004]
As a method, for example, a side piece is formed by bending the peripheral portion of the panel downward, and the side piece is formed into a concave groove formed on the upper surface of the base support or a concave formed between adjacent supports. A method of fixing a panel to a base by fitting in a groove or the like has been invented.
[0005]
[Problems to be solved by the invention]
However, in such a method, if the concave groove is formed with a narrow width, a gap is hardly generated between the back surface of the side piece and the inner surface of the concave groove, and the lateral displacement of the panel is prevented. Although it is necessary to detachably attach to the base so that maintenance in the wiring space can be performed freely, the side piece and the inner surface of the groove are In some cases, the frictional resistance of the panel becomes large, making it difficult to remove the panel from the base.
[0006]
Conversely, if the concave groove is formed wide, a gap is generated between the back surface of the side piece and the inner side surface of the concave groove, so that not only the lateral displacement of the panel cannot be prevented, but also between the peripheral portions of adjacent panels. There is a problem in that a gap is generated, and dust or the like enters the wiring space from this gap, or a collision sound between panels occurs when walking on the floor surface.
[0007]
The present invention has been made paying attention to such problems, and provides a double floor that is less likely to cause lateral displacement of the panel even when a load is applied to the floor and that can be easily attached to and detached from the base. With the goal.
[0008]
[Means for Solving the Problems]
In order to solve the above problems, the double floor of the present invention comprises a base formed by connecting a plurality of supports having a substantially constant height, and a panel constituting the floor surface is placed on the base. In the double floor where the space between the base and the panel is a wiring space,
The panel is formed in a square shape, and a vertical plate is bent downward from the side portion, and the base is formed in a square shape from a synthetic resin, and is a support body 5A erected at the center of the base. A support body 5D erected at the four corners of the base, a support body 5F erected at the side of the base between the support bodies 5D and 5D erected at the four corners, and a center of the base. A support body 5C standing between the support body 5A provided and the support body 5D standing up at the four corners of the base, except for the support body 5D standing up at the four corners of the base. body 5A, 5C, grooves 8, 12, 13 are formed in the upper part of the 5F, by fitting the vertical plate within these grooves 8, 12, 13, 4 which is laid on the base At least four corners of each panel are supported by the supports 5A, 5C, 5D, and 5F. It has, the inside surface of the upper which is formed in the recessed groove 12 of the support member 5C is characterized in that elastic piece contacting elastically against the said vertical plate are projected inward.
According to this feature, when the side piece of the panel is fitted in the groove, the side piece comes into contact with the elastic piece, and the opposing surfaces of the adjacent side pieces are brought into close contact with each other. They are integrated with each other, making it difficult for lateral displacement to occur. Further, even if the elastic piece is protruded largely laterally from the inner surface of the concave groove to increase the close pressure between the opposing surfaces of the side pieces, the contact area between the side pieces and the elastic pieces is small, and the elastic pieces have elastic force. Therefore, the panel can be attached to and detached from the base relatively easily.
[0009]
In the double floor of the present invention, it is preferable that the elastic piece protrudes from the inner surface of the concave groove so as to extend in the vertical direction.
In this way, since the resistance force by the elastic piece when the side piece is fitted into the concave groove from the upper side and when it deviates upward is reduced, the panel can be easily attached to and detached from the base. The piece and the support can be integrally formed.
[0010]
DETAILED DESCRIPTION OF THE INVENTION
DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings. First, FIG. 1 shows a main part of a double floor as an embodiment of the present invention. A base 1 that is laid on F and forms a storage space S for articles such as telephone lines and cables on the building floor F, and is supported above the building floor F by this base 1 to form a floor surface. And the panel 2 to be configured. 3 is a carpet laid on the panel 2, and 4 is a cable disposed in the storage space S.
[0011]
The base 1 is made of synthetic resin, and as shown in FIGS. 1 to 3, a plurality of supports 5 </ b> A to 5 </ b> E having a predetermined height and standing at appropriate intervals, and the supports 5 </ b> A to 5 </ b> E. The connecting ribs 7 that connect the bases 6 are formed in a substantially square shape in plan view.
[0012]
The support body 5A is composed of quarter-divided cylindrical support bodies 5a to 5d erected at the center of the base 1, and the support body is between the quarter-split cylindrical support bodies 5a to 5d. A groove 8 extending from the upper end to the upper surface of the base 6 is formed in a cross shape. Further, the center side of these quarter-divided columnar supports 5a to 5d is cut out, a concave portion 9 having a circular cross section is formed at the center, and a circular hole portion 10 is formed at the center position of the base portion 6. The upper surface of the building floor F is exposed in the hole 10 from above the base 1. Further, ribs 11 described later are formed between the quarter-divided columnar supports 5a and 5b and between the quarter-divided columnar supports 5c and 5d.
[0013]
A cylindrical support 5B and a support 5C are erected around the support 5A. In particular, the longitudinal direction of the groove 8 provided in a cross shape on the support 5A is provided above the support 5C. A concave groove 12 is provided along the extended line. A substantially quarter-divided cylindrical support 5D is provided at the four corners of the base 1, and a substantially half-divided cylindrical support 5E between the supports 5D and 5D on the side of the base 1 and 1 / A support body 5F composed of four divided columnar support bodies 5f and 5g is provided upright. Further, between the quarter-divided cylindrical supports 5f and 5g, a groove portion 13 is formed along an extension line in the longitudinal direction of the groove portion 8, and a rib 14 having the same shape as the rib 11 is formed. ing. In FIG. 2, the lower side and right side supports 5E and 5F of the base 1 are the same as the upper side and left side supports 5E and 5F, and the description of the reference numerals is omitted.
[0014]
These supports 5A to 5F have rigidity that hardly deforms even when a load is applied from above, and the base 6 and the connecting rib 7 correspond to the unevenness of the building floor F by the supports 5A to 5E. Flexible enough to be grounded to the floor.
[0015]
The base 1 is formed with a size of about 50 cm on one side. When the plurality of bases 1 are laid on the building floor F, the engagement recesses 15 and the engagement formed on the respective side portions are provided. The convex portions 16 can be connected to each other by engaging with the engaging concave portions 15 and the engaging convex portions 16 of the other adjacent bases 1.
[0016]
In FIG. 2, a hatched portion is an adhesive portion 17 for fixing the base 1 to the building floor F. As shown in FIG. 3, the adhesive portion 17 is slightly undulated upward (about 2 to 3 mm in height), and is a concave portion that can appropriately accommodate an adhesive on the back surface of the base portion 6 or the connecting rib 7. 18 is formed. Therefore, when the base 1 is fixed, by applying an adhesive in the recess 18, the height of the base 1 changes even if an adhesive layer is formed between the base 1 and the building floor F. In addition, the adhesive can be prevented from sticking out to the side of the base 6 and the connecting rib 7 and adhering to the cable 4 or the like disposed between the supports 5A to 5F.
[0017]
By laying the base 1 constructed in this way on the building floor F, the steel panel 2 can be supported above the building floor F as indicated by the two-dot chain line in FIG. A storage space S such as a cable 4 is formed between 2 and the building floor F. Since each of the supports 5A to 5F has a height of about 50 mm, a storage space S having a height of about 50 mm is formed. However, the supports are set in advance to various heights. By preparing the base 1 having 5, a storage space S having a size corresponding to the site can be formed.
[0018]
As shown in FIG. 3, the panel 2 in this embodiment has a vertical plate 2 a that is bent downward from each side portion and is fitted into the groove portions 8, 13 and the recessed groove 12, and the bases 1 are connected to each other. Are fitted in grooves (not shown) formed between the outer sides of the supports 5D, 5E, 5F facing each other, and four panels 2 can be laid on one base 1. I can do it. And the lower surface 2b predetermined part of the panel 2 is contact | abutted and supported by the upper surface of each support body 5A-5F.
[0019]
Note that a plurality of slit holes 19 (see FIG. 1) are formed on the diagonal line of the panel 2, and the panel 2 is formed so as to be bent around the slit holes 19. Even if the supports 5A to 5F are higher or lower than the upper ends of the other supports 5A to 5F corresponding to the uneven building floor F, the backlash of the panel 2 is absorbed by bending. It can be done. Further, as shown in FIG. 1, a notch 20 is formed at a predetermined position of the vertical plate 2a, and when the panels 2 are connected to each other, the notch 20 facing each other is used for inserting the cable 4 or the like. Since the hole is formed, the cable 4 and the like can be easily pulled out between the panels 2 and 2.
[0020]
As shown in FIG. 3, the supports 5 </ b> A to 5 </ b> F are each formed in a hollow shape, and the outer diameter becomes smaller as the upper inner diameter L <b> 1 becomes smaller than the lower inner diameter L <b> 2, that is, as it goes upward. When the base 1 is stacked up and down in the same direction because it is formed in a taper shape, the upper part of the support 5A to 5F of the lower base 1 is fitted in the lower opening of the support 5A to 5F of the upper base 1 It has come to be. Therefore, a plurality of bases 1 can be stacked in the vertical direction in a compact manner, and since they do not become bulky when stacked, they can be transported and stored efficiently.
[0021]
In addition, the lower surfaces of the bases 6 positioned at the lower ends of the upper ribs 11 and 14 are brought into contact with the upper ends of the ribs 11 and 14 of the lower supports 5A to 5F, and above the upper portions of the lower supports 5A to 5F. Since the depth of entry of the supports 5A to 5F into the lower opening is restricted, the upper and lower supports 5A to 5F are not tightly fitted to each other so that they are not easily separated. In addition, since the ribs 11 and 14 are formed in the groove portions 8 and 13 or the concave groove 12 as described above, the ribs 11 and 14 do not interfere with the wiring.
[0022]
As shown in FIGS. 3 and 4, elastic pieces 30 having a predetermined elastic force project inwardly in the vertical direction of the inner surface of the concave groove 12 formed in the support 5 </ b> C. As shown in FIG. 4, when the panel 2 is placed on the supports 5 </ b> A to 5 </ b> F and the vertical plates 2 a and 2 a of the panel 2 adjacent to each other are fitted in the concave groove 12, the panel 2 protrudes inward. Since the inner surface of the vertical plate 2a is brought into contact with the tip of the elastic piece 30, the outer surfaces of the vertical plates are brought into close contact with each other.
[0023]
As a result, there is no gap between the adjacent panels 2 and the plurality of laid panels 2 are integrated as a whole, so that lateral displacement of the panel 2 with respect to the base 1 is prevented. Further, for example, even when a lateral force is locally applied to a part of the panels 2, the force is dispersed throughout, so that only the panel 2 and the support that supports the panel 2 are used. Thus, only a part of the support is not easily damaged.
[0024]
Thus, since the elastic piece 30 protrudes inward and laterally from the inner surface of the groove 12, the hanging plates 2a of the panel 2 are firmly in contact with each other and the contact area with the hanging plate 2a is small. In addition, since it has elasticity, it does not become difficult to fit and divide the vertical plate 2a into the concave groove 12, and maintenance in the storage space S with the panel 2 opened is easy. Can be done.
[0025]
Since the protruding length of the elastic piece 30 from the inner side surface of the concave groove 12 can be arbitrarily changed, if it is formed in advance relatively long, the vertical plates 2a can be more firmly brought into close contact with each other. Further, since it is formed so as to extend in the vertical direction, the resistance force at the time of fitting and escaping operation of the vertical plate 2a into the concave groove 12 is reduced, and the panel 2 can be attached to and detached from the base 1 relatively easily. In addition, the elastic piece 30 can be integrally formed with the supports 5A to 5F.
[0027]
Although the embodiments of the present invention have been described with reference to the drawings, the specific configuration is not limited to these embodiments, and modifications and additions within the scope of the present invention are included in the present invention. It is.
[0028]
For example, although the elastic piece 30 in the present embodiment is formed in a strip shape facing in the vertical direction, the shape is not particularly limited, and may be formed so as to protrude inwardly on the inner surface of the groove 12. That's fine.
[0029]
【The invention's effect】
The present invention has the following effects.
[0030]
(A) According to the invention of claim 1, when the side piece of the panel is fitted in the groove, the side piece is brought into contact with the elastic piece, and the opposing surfaces of the adjacent side pieces are brought into close contact with each other. Therefore, the laid panels are integrated with each other, so that it is difficult for lateral displacement to occur. Further, even if the elastic piece is protruded greatly in the lateral direction from the inner surface of the concave groove to increase the close pressure between the opposing surfaces of the side pieces, the contact area between the side pieces and the elastic pieces is small, and the elastic pieces have elastic force. Therefore, the panel can be attached to and detached from the base relatively easily.
[0031]
(B) According to the invention of claim 2, since the resistance force by the elastic piece when the side piece is fitted into the concave groove from the upper side and the deviation from the upper side is reduced, the panel can be attached to and detached from the base. In addition to being easy, the elastic piece and the support can be integrally formed.
