Active raised floor

The present invention relates to a movable raised floor which is arranged on a slab of a building, that is, on a floor surface, and the raised floor piece is gathered at a seat at a corner of the plate. The configuration is erected and placed in the socket of the support frame.

In a building such as an office building, a large number of electronic devices such as a photocopying machine and a computer are disposed in the room, and in order to accommodate wiring of such electronic devices, a movable raised floor is widely used, and the raised floor is laid on the floor of the building. The movable raised floor will support the raised floor support frame on the floor of the building, ensuring the space for arranging the wiring between the floor surface and the raised floor, so that the wiring of the electronic device will not be exposed on the top surface of the raised floor, and the comfort can be achieved. Office environment.

The floor surface of a building, especially when the floor area is large, is likely to cause errors in level. Therefore, the movable raised floor is laid in the following manner: erecting the elevated floor piece, so that the support frame supporting the raised floor has the function of adjusting the up and down position of the raised floor, and adjusting the support frame to set the raised floor surface to a horizontal state. In this type of raised floor, the focus is on the raised floor panels to be sturdy, durable and easy to lay.

The raised floor tiles come in various types. For example, Patent Document 1 discloses a hollow elevated floor panel 30 which is formed by an upper plate 10a and a lower plate 10b, and has a space formed therein. Further, in this case, it is characterized in that a reinforcing structure 30a is provided at a corner portion of the four corners.

(The problem that the invention wants to solve)

As disclosed in Patent Document 1, a metal and hollow raised floor sheet is relatively lightweight and formable, but has the following problems: sometimes it is recessed under a concentrated load, and then it may rust, make a footstep, or vibrate the machine. Wait. As the resin of Patent Document 2 is rich in formability, it is difficult to fix dimensional accuracy. Further, it is considered that there is a deflection and deformation due to a load, or a deterioration in strength due to a long-term change in material. The raised floor sheet of Patent Document 3 is formed into a concrete body which is excellent in durability, vibration absorption, and non-deformation, but is not good in formability, is easily cracked, and has an edge on the bottom side of the sheet when laying. The problem of missing corners due to contact with other objects. Further, the arc inner peripheral surface 5f is a hole that penetrates upward at the four corners, and must be sealed.

It is an object of the present invention to provide a movable raised floor which has an elevated floor panel which is excellent in durability, vibration absorption, and non-deformation, and which is easy to lay. (the way to solve the problem)

Use raised floor panels and support frames to form a raised raised floor.

A plurality of support frames are prepared, which are constructed by erecting pillars on the bottom plate and mounting the sockets so as to be vertically penetrated by the pillars.

The raised floor sheet is constructed by using a main board and a reinforcing steel plate covering the bottom surface of the main board.

The main board is further shaped into a compression-formed calcium silicate board, which is substantially a uniform thickness of the square plate in plan view, and the side surface (thickness direction) is formed to have a vertical surface and a tilt of the vertical plane below the in-plane direction. The shape of the face.

Further, the four corners on the bottom surface side are formed with a cut concave portion that accommodates the top of the pillar of the support frame from the bottom surface side. The cut recess does not penetrate the recess on the top surface side.

Reinforced steel plate, when expanded, has a slightly larger area than the bottom surface of the motherboard. Moreover, when splicing to the bottom surface of the main board, the portion extending from the bottom surface to the periphery of the main board is folded up along the push-out surface of the main board to maintain a rib shape.

The four corners of the reinforcing steel plate are cut away to expose the cut recess.

And the raised floor piece is fixed on the side of the floor with the reinforcing steel plate side as the bottom surface, the vertical surface around the main board abuts the vertical surface of the other raised floor piece, and the corner portion of the plate piece is gathered at the seat, and the erection is placed on the floor. The majority of the support frame of the support.

In addition, at this time, of course, the seat height of the support frame is adjusted to adjust the level of the entire raised floor. (Effect of the invention)

The calcium ruthenate board by compression molding is less likely to cause deterioration and deformation of the material, and has high durability. Moreover, since the structure is solid and dense, vibration is hard to transmit and vibration absorption is excellent, so that a raised floor which is stable over a long period of time can be realized. Since there is almost no deflection caused by the load of each raised floor tile, a firm walking feeling can be obtained.

After the laying, each of the raised floor sheets abuts on the vertical faces of the sides, and finally comes into contact with each other, so that there is no horizontal offset or bounce of the plates, and the laying state is stable.

(Preferred form of implementing the invention)

Hereinafter, several embodiments of the present invention will be described in detail. The embodiments described below are preferred embodiments of the present invention, and thus the present invention is not limited thereto, and the present invention is not limited thereto, and the present invention is not limited thereto.

Figure 1 is a top plan view showing a portion of a completed raised raised floor 1 showing a portion of four raised floor panels 2a, 2b, 2c, 2d. Here, when each of the raised floor sheets is not distinguished, it is called the raised floor sheet 2. The four corner collecting portions 3 are supported by the support frame 4 on the bottom surface side.

A portion of the raised floor panel 2 as shown in Fig. 2 is laid by assembling the corner portions of the raised floor panel 2 on the socket 5 and erecting a majority of the support placed on the floor surface of the building. There are 5 seats in the frame 4.

As shown in FIG. 3, the support frame 4 is provided with a pillar 7 standing upright on the bottom plate 6, and the socket 5 is mounted so as to be penetrated by the pillar 7 so as to be vertically adjustable. Specifically, the stay 7 is a screw, and the female screw portion 8 at the center of the socket 5 is screwed thereon. The component symbol 9 is a stop screw. Rotate the socket 5 to determine the up and down position, and screw in the stop screw 9 to fix its position. The socket 5 is protruded from the top surface: four positioning protrusions 5a are formed to face each other along the cross line at the intersection. Further, on the top surface of the socket 5, a cushioning material 5b made of synthetic rubber is adhered to a central portion surrounded by the projection 5a.

The raised floor panel 2 is composed of a main board 10 and a reinforcing steel plate 11.

The main board 10 is a high-density solid calcium silicate board which is compression-molded, and basically has a substantially square shape of 500 mm × 500 mm and a thick plate of thickness of 23.5 - 31 mm in plan view as shown in Fig. 4 . In addition, the thickness varies depending on the allowable concentrated load. Moreover, the thickness in Fig. 4 is exaggerated. Further, the side surface in the thickness direction of each of the four sides is defined as a vertical surface 12 and a push surface 13 which is inclined in the in-plane direction below the vertical surface.

In the present embodiment, the main board 10 is formed by molding a material obtained by mixing a bismuth acid raw material, a calcareous raw material, and fly ash with water, and performing steam treatment using high temperature and high pressure, followed by drying to obtain an original plate (Fig. 4). Next, the front and back surfaces of the original plate are ground and trimmed, and the side surface is ground into the vertical surface 12 and the push surface 13. Furthermore, in the four corners of the bottom surface, the depth is approximately 10 mm from the bottom surface, and is cut into a circle having a square shape, that is, a circle having a diameter of approximately 10 mm centered on the apex, forming a 1/4 circular cut. Concave portion 14.

Since the cut concave portion 14 has a depth of 10 mm from the bottom surface side, the concave portion does not reach the top surface so that the corner portion becomes a notch. Further, since the cutting action is applied to the push-out surface 13, the corresponding portion of the cut concave portion 14 has a concave conical shape (Fig. 6).

The reinforcing steel plate 11 (Fig. 5) has a thickness of about 0.3 mm, and in the present embodiment, nickel plating is applied. When the reinforcing steel plate 11 is unfolded, it has a larger area than the bottom surface of the main plate 10, and the portion projecting from the bottom surface of the main plate is folded upward so that the rib 15 has a rib shape. Further, the four corners of the reinforcing steel plate 11 are cut together with the rib 15 at a quarter of a circle corresponding to a radius slightly larger than the radius of the cut concave portion 14. The rib 15 is folded along the push-out surface of the main plate, and the edge faces the push-out surface 13. The reinforcing steel plate 11 is adhered to the bottom surface of the main board 10, and dustproof coating is applied to the front surface of the main board 10 to complete the elevated floor sheet 2.

The movable raised floor 1 is constructed by the following procedure.

First, a plurality of support frames 4 are disposed at the position of the support frame set on the floor surface of the building, for example, the intersection of the matrix of 500 mm intervals, and the upper and lower positions of the respective seats 5 are adjusted.

The elevated floor panel 2 is arranged such that the vertical surface 12 around the main board 10 abuts on the side of the reinforcing steel plate 11 and the corner portions of the raised floor panel 2 are gathered at the respective seats 5, and the mounting is placed on the majority The seat 5 of the support frame 1 is (Fig. 1).

At this time, each of the sockets 5 is a four corner collecting portion 3 (FIG. 1) in which the corner portions of the four raised floor panels 2a to 2d are assembled, and the corner portions of the raised floor panels 2a to 2d are as shown in FIG. The bottom surface of the raised floor panel 2 is mainly supported by the support frame 4 at the point where the reinforcing steel plate 11 is in contact with the cushioning material 5b, and the cut concave portion 14 on the bottom surface side of each corner portion is concentrated to form a cylindrical space 16 which is oriented toward the space. The strut 7 of the support frame 4, that is, the top of the screw. That is, even when the height of the socket 5 of the support frame 4 is lowered, the top portion of the pillar 7 is more protruded than the top surface of the socket 5, and the cylindrical space 16 can be absorbed and height-adjusted. Further, since the cylindrical space 16 does not penetrate the top surface of the raised floor panel 2, the four corner collecting portions 3 do not need to have a closing member.

The reinforcing steel plate attached to the bottom surface of the main board 10 is a reinforcing of the main board 10, because the protruding portion of the surrounding portion is folded upward as the rib 15 so that the edge faces the pushing surface of the main board 10, so that the reinforcing steel plate 11 can be prevented. Damage caused by sharp edges.

Further, the corner portion of the raised floor panel 2 placed on the socket 5 is restricted by the positioning projection 5a of the top surface of the socket 5, and is guided to the correct position on the socket 5, so that it is easy to set. At this time, since the contact of the positioning projection 5a with the raised floor panel 2 is performed by the rib portion 15 of the reinforcing steel plate 11 of the pushing surface of the raised floor panel 2, the raised floor panel 2 is not damaged during the erection. Further, when the raised floor panel 2 is placed on the socket 5, the positioning projection 5a is accommodated in the bottom wide triangular space formed by the pushing surface 13 of the raised floor panel 2, and the elevated floor panel 2 is placed against each other. There will be no obstacles.

Furthermore, since the laid raised floor sheets 2 are in contact with each other on the vertical surface 12 of the main board 10, even if lateral pressure acts for various reasons, no component of the component containing the up-and-down direction is generated due to the pressure, and Bounce (Figure 8).

On the other hand, in the embodiment, the vertical surface 12 is positioned approximately half of the thickness dimension and the lower half is defined as the push-out surface 13, so that even if the raised floor panels 2 on both sides are in contact with the vertical surface 12, it is easy Work to remove the raised floor sheet 2 or insert the last raised floor sheet. Moreover, since the portion in contact with the vertical surface 12 does not reach the entire thickness dimension, the frictional sound generated when the person walks on the raised floor panel 2 becomes less.
