Abstract

PROBLEM TO BE SOLVED: To provide a double floor utilizing a base which can be adhered to a placing floor face without projecting an adhesive agent out of the base. SOLUTION: When a base 1 is placed on a placing floor face F since an adhesive agent (g) in a recessed part 18 is enclosed in a space formed of the recessed part 18 and the placing floor face F and expands only in the space, the adhesive agent (g) does not project out of the base 1. Therefore a wiring process can be carried out without waiting hardening of the projected adhesive agent (g) and the adhesive agent (g) does not obstruct the wiring process in a hardened projected state. In addition, since an adhesive layer is not formed in a spot except the space, the reference height of the base 1 can be certainly arranged as a floor face.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field 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]

2. Description of the Related Art Conventionally, in order to realize wiring under the floor in an office, a double floor having a space for accommodating and wiring telephone lines, computer cables and the like on a floor of a building has been often used. ing.

As a method of constructing such a double floor, for example, Japanese Utility Model Application Laid-Open No. 63-54726 and
As shown in No. 2776, etc., first, a plurality of support members are connected to form a rectangular base on the floor of a building, and panels are laid on the support members of these bases.
A method of laying a decorative floor material such as a carpet on the panel is known.

In a double floor formed by using these bases, an adhesive is applied to the floor at the time of construction so that the floor does not shift during construction or use, and the base is further coated with an adhesive. Is mounted and fixed.

[0005] These bases are formed with a plurality of holes penetrating from the adhesive surface to the upper surface of the base, and excess adhesive is guided from the holes to the upper surface of the base when the base is pushed into the floor surface. Then, the adhesive guided to the hole portion securely fixes the base to the floor with an anchor effect.

[0006]

However, the cable or the like guided to the upper surface of the base and wired to the hardened adhesive may be caught or hindered, and may damage the cable or the like. There was fear. In addition, there is a problem in that wiring cannot be performed on the upper surface of the base until the adhesive is hardened, and the construction time is prolonged.

The present invention has been made in view of such a problem, and a double floor using a base which can be bonded to a mounting floor surface so that the adhesive does not protrude from the base is provided. The purpose is to provide.

[0008]

In order to solve the above-mentioned problems, a double floor according to the present invention comprises a base formed by connecting a plurality of supports having substantially constant heights, and a floor surface on the base. When the base is installed on a mounting floor surface at a predetermined location on the back surface of the base, the mounting floor is placed on a double floor having a wiring space between the base and the panel. A recess that can form a void is formed between the surface and the surface,
The inside of the concave portion is characterized in that an adhesive for fixing the base to the mounting surface can be injected. According to this feature, when the base is placed on the mounting floor surface, the adhesive in the concave portion is trapped in the void formed by the concave portion and the mounting floor surface, and is likely to spread only in the void. Therefore, the adhesive does not protrude from the base. Therefore, the wiring can be performed without waiting for the protruding adhesive to be hardened, and the adhesive hardened in the protruding state does not hinder the wiring. Further, since the adhesive layer is not formed except in the vacant space, the reference height of the base can be reliably provided as the floor surface.

[0009] In the double floor according to the present invention, it is preferable that the base is rectangular and the recess is formed at least near a corner of the base. This makes it difficult for the peripheral portion of the mounted base to be turned up.

[0010] In the double floor of the present invention, it is preferable that the surface of the concave portion in the base is formed so as to be elastically deformable in the vertical direction. With this configuration, when the base is mounted on the mounting surface, the concave portion is elastically deformed to absorb the spread of the surplus adhesive, so that the surplus adhesive does not easily protrude. Further, when the upper surface is deformed upward, the adhesive is pressed against the ground surface by the elastic return action, so that a reliable bonding effect can be obtained.

Therefore, when the base 1 is fixedly installed, an adhesive is applied to such a concave portion 18 as described later, so that an adhesive layer is formed between the base 1 and the building floor F. Not only does the height not change, but it is also possible to prevent the adhesive from protruding to the sides of the base 6 and the connecting ribs 7 and from adhering to the cable 4 disposed between the supports 5A to 5F.

The base 1 constructed as described above is mounted on a building floor F
By laying it on top, the steel panel 2
It can be supported above the building floor F as shown by the dashed line, and a cable 4 is provided between the panel 2 and the building floor F.
Is formed. These supports 5A to 5F
Since the height of each is about 50 mm, the height is about 50 mm.
A storage space S having a height of a little less than mm is formed, but by preparing a base 1 having a support 5 set at various heights in advance, a storage space having a size corresponding to the site can be obtained. Space S
Can be formed.

As shown in FIG. 3, the panel 2 according to the present embodiment has vertical plates 2a bent downward from the respective sides thereof fitted into the grooves 8, 13 and the concave grooves 12, and When the bases 1 are connected to each other, four panels 2 are fitted on a groove (not shown) formed between the outer sides of the supports 5D, 5E, and 5F facing each other.
Can be laid. A predetermined portion of the lower surface 2b of the panel 2 comes into contact with and is supported by the upper surface of each of the supports 5A to 5F.

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 that the panel 2 is bent around the slit holes 19. Even when one of the supports 5A to 5F is higher or lower than the upper ends of the other supports 5A to 5F in correspondence with the uneven building floor F, the panel 2 has a play by bending. It can absorb the light. 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 notches 20 opposed to each other are used to insert the cable 4 or the like. Since the hole is formed, the cable 4 and the like can be easily pulled out from between the panels 2 and 2.

As shown in FIG. 3, each of the supports 5A to 5F has a hollow interior, and the upper inner diameter L1 is smaller than the lower inner diameter L2. When the bases 1 are stacked vertically, the upper portions of the supports 5A to 5F of the lower base 1 are placed in the lower openings of the supports 5A to 5F of the upper base 1 because the bases 1 are stacked vertically. It is adapted to be fitted (not shown). Therefore, even when the plurality of bases 1 are stacked compactly in the up-down direction, they do not become bulky, so that they can be efficiently transported and stored.

Also, the lower supports 5A to 5A
The upper ribs 11 and 14 are provided at the upper ends of the ribs 11 and 14 of 5F.
The lower surface of the base 6 located at the lower end of the lower support 5 is in contact with the lower support 5A to 5F, so that the depth of entry of the upper support 5A to 5F into the lower opening of the upper support 5A to 5F is regulated. The support members 5A to 5F are not tightly fitted to each other and are not easily separated. Note that, as described above, the ribs 11 and 14
Are formed in the grooves 8, 13 or the concave grooves 12, so that the ribs 11, 14 do not interfere with the wiring.

Next, the base 1 on which a plurality of adhesive portions 17 are formed

The adhesive g is provided so as to be slightly higher than the lower surface 1a of the base 1 around the center of the recess 18. At this time, the amount of the adhesive g is preferably set to be slightly smaller so as not to greatly exceed the volume of the concave portion 18 and higher than the lower surface 1a so as not to spread in the lateral direction.

Next, as shown in FIG.
Is turned over again from the state of FIG. 5A, and the base 1 is placed on the upper surface of the building floor F. When the base 1 is placed, FIG.
As shown in (c), the adhesive g, which is mounted high in the center of the recess 18, spreads in the left and right directions in the recess 18 by being pressed against the upper surface of the building floor F. At this time, the concave portion 18
The space formed by the floor and the building floor F absorbs the spread of the adhesive g in the lateral direction, so that the adhesive g does not protrude from the base 1.

Before the adhesive g is hardened, the base 1 is connected to the other base 1 via the engaging projections 16 and 17.
Fine adjustment of the position, orientation, etc., while connecting with. Here, even if the base 1 is not pressed against the building floor F after laying,
Since the thick adhesive layer is formed over a wide range in the left-right direction in the concave portion 18, the adhesive force of the base 1 to the building floor F is increased, and the thickness of the adhesive layer acts to particularly support the bases 5A to 5F of the base 1. No difference in height.

Finally, after the adhesive g is cured and the base 1 is fixed, the panel 2 is laid on each of the supports 5A to 5F.
Further, a decorative floor material such as a carpet 3 is laid on the panel 2 to complete a double floor.

As described above, the base 1 is attached to the concave portion 1 of the bonding portion 17.
By being fixed to the building floor F with the adhesive g provided in the inside 8, the adhesive g protruding from the base 1 and hardening does not hinder the wiring, does not damage the cable 4 or the like, and also protrudes. Since there is no need to wait for the cured adhesive g to harden, the construction time is shortened.
