Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to an improvement of a double floor device in which floor panels are laid in line on a floor base made of concrete or the like.

[Conventional technology]

In recent years, in offices, in order to beautifully and safely process a large number of cords for OA equipment and the like, the floor is constructed as a double floor, and the inside of the floor is used as a wiring space for cords. .

As one example, in JP-A-62-107161 as a prior art, a block-shaped floor panel made of lightweight concrete or reinforced plastic is directly and vertically aligned on a floor base made of concrete or the like. In laying on, on the upper surface of each floor panel, a cord insertion groove is formed so that the cord insertion grooves of adjacent floor panels communicate with each other,
Furthermore, a step is formed on the upper part of both sides of the cord insertion groove,
It is disclosed that a cover body for closing the cord insertion groove is detachably placed on the step portion.

On the other hand, in Japanese Patent Publication No. 1-207565 as another prior art, floor panels that are rectangular in plan view and are formed by bending a metal plate into a trapezoidal cross section are laid vertically and horizontally to lay adjacent floors. It is described that a cord insertion groove is formed between the side surfaces of the panel and that a cover body made of a metal plate is spread over the upper surface of the floor panel.

Further, according to these two prior arts, the cord can be put in and taken out from the cord insertion groove only by removing the cover body, so that there is an advantage that the wiring work can be performed quickly.

[Problems to be solved by the device]

However, in the former prior art, since the cover body is attached to each floor panel, it is necessary to accurately align each floor panel before mounting the cover body. There was a problem that the laying work was troublesome.

On the other hand, in the latter prior art, the cover body is formed in the same planar shape as each floor panel, and the cover body is placed so as to be in a state of straddling four floor panels adjacent to each other, Furthermore,
The cover body is positioned by fitting the recesses formed on the cover body with the protrusions formed on each floor panel. However, in this configuration, since the convex portion of the floor panel is hidden by the cover body when the cover body is placed, the concave portion of the cover body may not be projected in the concave portion of the cover body unless the floor panels are accurately aligned in advance. However, even in this latter prior art, the problem that the floor panel laying work is troublesome still remains.

On the other hand, air conditioning such as heating and cooling in offices is performed by blowing warm air or cold air through a duct.In general, this air conditioning duct is installed behind the ceiling to blow warm air or cold air down from the ceiling surface. Therefore, even in the office with the double floor of the above-mentioned prior art, such an air conditioning structure is provided.

However, in this conventional air-conditioning unit, since the hot air and cold air outlets are separated from the person, the heat is diffused a lot and the air-conditioning efficiency is low, and the air-conditioning is finely adjusted according to the room layout. In addition, the duct must be suspended from a beam, etc., so it takes a lot of time and money to install it, and there is a risk that it will fall off and damage people and things if there is an earthquake. There was a problem that said.

SUMMARY OF THE INVENTION An object of the present invention is to provide a double-floor device that enables quick alignment of floor panels and solves air conditioning problems.

[Means for Solving the Problems]

In order to achieve this object, the present invention proposes, "By installing a number of floor panels supported by legs on a floor base of a building in an aligned manner, an air conditioning duct is provided between the floor base and the floor panel. Etc. are formed in any vertical and horizontal directions, and at least two cord insertion grooves extending in a plan view cross each other are formed on the upper surface of each floor panel so that the cord insertion grooves of adjacent floor panels are mutually adjacent. The cord insertion groove is formed so as to communicate with each other, and an upwardly projecting island portion is intermittently provided in the cord insertion groove along the longitudinal direction, and further, the cord insertion groove is closed while being supported by the island portion. The cover body
It is provided so as to extend across the cord insertion grooves of the adjacent floor panels, and the cover body cannot be laterally displaced in both the vertical and horizontal directions by contacting the side surface of the island portion and the inner side surface of the cord insertion groove of the adjacent floor panels. The foot piece that is supposed to be held at the position is projected downward. "

[Function and effect of device]

According to this structure, the positions of the adjacent floor panels are regulated by the cover body. In other words, the floor panel can be positioned by mounting the cover body.

In this case, since the cover body closes only the cord insertion groove, it is extremely easy to attach the cover body to the cord insertion groove of the adjacent floor panel, and moreover, the foot piece formed on the cover body is used for the cord. Since the inner surface of the insertion groove and the side surface of the island portion are brought into contact with each other, the cover body can be firmly locked to the island portion,
As a result, the floor panel can be reliably positioned, and the floor panel can be prevented from laterally slipping after installation.

Therefore, according to the present invention, it is possible to efficiently lay a floor panel at an accurate position and prevent lateral displacement of the floor panel after laying. Further, since the cover body is supported by the island portion, there is an effect that the support strength of the cover body can be improved.

In addition, since it is possible to install ducts for air conditioning in the space between each floor panel and floor base, it is possible to provide heating and cold air outlets for air conditioning close to people. Therefore, it is possible to prevent the diffusion of heat and improve the efficiency of air conditioning. Moreover, by pre-preparing the air conditioning holes in the floor panel, etc. Since an air suction port or the like can be easily provided at any part of the room, it becomes possible to perform fine air conditioning according to the layout of the room very easily.

Furthermore, since the wiring space for cords and the piping space for air conditioning ducts, etc. are separated from each other at the top, the wiring work can be performed even when the cords are wired while intersecting with the air conditioning duct in plan view. Not only can it be done easily, but the cords can be wired in a crossed state in plan view without contacting the outer surface of the duct, so even if there is a risk of dew condensation on the outer surface of the duct, take any measures against condensation. In addition, it is sufficient to place the air conditioning duct directly on the floor base, which can significantly reduce the installation labor and cost and prevent earthquakes. However, it does not damage people or things at all.

〔Example〕

 Next, an embodiment of the present invention will be described with reference to the drawings.

In the figure, reference numeral 1 indicates a rectangular floor panel which is laid vertically and horizontally on a floor base A made of concrete or the like. The floor panel 1 is made of lightweight cellular concrete, reinforced plastic, or aluminum die cast. It is formed in a block shape, and on its upper surface, two cord insertion grooves 2 extending vertically and horizontally are formed so that the cord insertion grooves 2 of adjacent floor panels 1 communicate with each other. . Further, adjuster bolts 3 as an example of legs are screwed on the lower surfaces of the four corners of each floor panel 1 to make each floor panel 1
A gap is formed between the lower surface of the floor and the floor base A in which the air conditioning duct 4 can be arranged.

Tool insertion holes 5 for inserting a driver tool (not shown) for the adjuster bolt 3 are opened in the upper surfaces 1a of the four corners of each floor panel 1.

The cord insertion groove 2 is formed with island portions 1b and 1c that extend intermittently along the longitudinal direction thereof, and the intersection of the cord insertion groove 2 is formed by the center cover body 7 supported by the center island portion 1c. The side surface of the cord insertion groove 2 outside the center cover body 7 is closed by the side cover body 6 supported by the side island portion 1b.

In this case, the side cover bodies 6 are arranged so as to extend over the cord insertion grooves 2 of the floor panels 1 adjacent to each other.

On each of the side cover bodies 6, a foot piece 6b that abuts the inner side surface of the cord insertion groove 2 and a foot piece 6a that abuts the side surface of the side island portion 1c are provided so as to project downward, whereby the side cover The body 6 is held so as not to be displaced in any of the vertical and horizontal directions. On the other hand, as clearly shown in FIG. 1, foot pieces 7a that abut the foot pieces 6a of the side cover body 6 are provided so as to project downward on the four circumferences of the center cover body 7.

The foot pieces 6a, 7a that come into contact with the island block bodies 1b, 1c are formed to the same extent as the width dimensions of the island portions 1b, 1c, respectively. The cutout groove 8 opens laterally.

It should be noted that the height of the islands 1b and 1c is only the thickness of the covers 6 and 7 as compared with the top 1a of the floor panel 1 so that the top of the cover 6 is flush with the top 1a of the floor panel 1. It is formed low.

Among the floor panels 1, any floor panel 1 located above the air conditioning duct 4 is provided with an air conditioning hole 10 for drawing out the blowout pipe 9 connected to the air conditioning duct 4. Cage, directly from the blowing pipe 9 or the fourth
As shown by the chain double-dashed line in the figure, warm air or cold air is blown out into the room through the control device 11 installed on the floor.

A carpet 12 is laid on the upper surface of the floor panel 1.

When laying the floor panel 1 in the above configuration, the floor panel 1 is accurately positioned by mounting the side cover body 6 and the center cover body 7 in the cord insertion grooves 2 of the adjacent floor panels 1. You can In this case, the side cover body 6 is mounted only in the cord insertion groove 2, and the side cover body 6 can be mounted in the cord insertion groove 2 very easily, so that the floor panel 1 can be accurately positioned. You can do it efficiently,
Lateral displacement of the floor panel 1 after installation can also be effectively prevented.

Also, by removing the cover bodies 6 and 7, the cord B can be freely wired in the cord insertion groove 2 of each floor panel 1, while the gap between the lower surface of each floor panel 1 and the floor base A. Air conditioning of the room can be performed by the air conditioning duct 4 provided in the.

In this case, since the air-conditioning duct 4 is provided inside the floor, the outlets for warm air and cold air can be brought closer to the person, so that heat diffusion can be prevented and efficient air conditioning can be achieved. Since the position of the blowing pipe 9 can be easily changed or added, it is possible to perform fine air conditioning according to the layout of the room.

Further, since the wiring space and the piping space such as the air conditioning duct are vertically separated, even when the cord B is wired so as to cross the duct 4 in a plan view, the wiring work can be performed without being obstructed by the duct 4. In addition to being able to perform quickly, even if there is a risk of dew condensation on the outer surface of the duct 4, it is possible to wire in a safe state without taking measures against the dew condensation. Since it can be placed directly on the floor base A, the installation work is extremely easy, and the labor and cost of installation can be significantly reduced.
It is possible to ensure safety in the event of an earthquake.
