Description

[Detailed description of the invention]

[0001]

[Industrial application field] The present invention provides a communication cable under the floor,
The present invention relates to an improvement in a connection structure of floor members used for a floor structure having a space in which wiring such as a power line can be formed, that is, a floor structure called an access floor.

[0002]

2. Description of the Related Art Conventionally, as a structure for connecting floor members for an access floor, arcuate grooves are provided at each corner of the upper surface of a floor panel having a rectangular flat plate, and the floor panel is laid on a floor slab. A structure in which grooves of adjacent floor panels are connected to form a circumferential locking groove, and a ring-shaped connecting tool is fitted into the locking groove to connect adjacent floor panels to each other. No. 2-87951.

[0003]

The floor panel connecting structure having the above-mentioned structure simply fits a ring-shaped connecting member into an arc groove on the floor panel side. Due to the backlash, there is a problem that the connecting tool easily rises out of the groove and comes off.

[0004]

SUMMARY OF THE INVENTION An object of the present invention is to provide a connecting structure of a floor member which can be securely held so that a connecting tool fitted to the floor member does not come off later.

[0005]

According to the present invention, a rectangular upper plate has leg plates at at least four corners, and a notch opening is provided at a corner of the upper plate to expose the corner of the leg plate. Board members arranged vertically and horizontally, and supported by the exposed portions of the leg plates of the four floor members adjacent to each other in the vertical and horizontal directions from the cutout openings, and regulating the mutual positions of the floor members; Protruding from the periphery of the floor part, elastically deforms when hitting the notch opening edge of each floor member when the board body is placed on the leg plate part, restores after passing through the notch opening and engages with the back surface of the top plate part The gist has a structure in which the floor members are connected to each other by a connecting tool including a hook portion that can be connected to the floor members.

[0006]

According to the above construction, when the connecting member is mounted on the floor member, the hook portion engages with the back surface of the floor member so that the connecting member does not come off from the floor member.

[0007]

1 to 4 show an embodiment of the present invention. In the figure, A is an access floor member formed by bending a metal plate into a box shape. Reference numeral 1 denotes a rectangular upper plate portion forming a floor member, 2a and 2b denote leg plate portions bent from the periphery of the upper plate portion, and a cutout opening 3 is provided at a corner of the upper plate portion 1; The ends of the portions 2a and 2b are exposed.

[0008] B is a connecting member formed of a synthetic resin.
This connecting tool integrally forms a V-shaped hook portion 5 which projects downward from the four corner portions of the board body portion 4 and then bends upward, and is integrally formed on the board body portion 4 with its side sides. A groove 6 extending in parallel with the symmetric axis intersecting the vertical axis, a groove 7 extending in parallel with the symmetric axis orthogonal to the symmetric axis, and extending from the back surface of the panel to approximately half of the thickness of the panel; Shallow V-shaped grooves 8 and 9 provided on both front and back surfaces of the board body corresponding to the axis of symmetry, and a circular through hole 10 provided at the intersection of both axes of symmetry.
And those having the following.

FIG. 1 (a) shows a state in which four floor members A adjacent vertically and horizontally are connected by a connecting member B.

As a connecting procedure, on a floor slab,
For the four floor members arranged vertically and horizontally at a required interval, the board body portion of the connecting member B is provided on the upper surfaces of the leg plate portions 2a and 2b exposed from the cutout openings 3 at the corners of the floor member A. 4, and the groove 7 on the back surface is positioned so as to match the leg plate 2a of each floor member A. In this state, the hook portion 5 is in contact with the edge of the notch opening 3. However, when the board portion 4 is pressed and the groove 7 is fitted to the leg plate portion 2 a, the hook portion 5 is Since it is depressed toward the center and released through the notch opening 3 at the same time, it returns to its original angular position due to its rebound resilience and engages with the back surface of the upper plate 1.
At this time, the leg plate 2b is sandwiched by the through-grooves 6 provided in the board body 4, and the position is regulated.

By assembling the connecting member B to the floor member A as described above, the four floor members A adjacent vertically and horizontally are connected, and the connecting member B is firmly held so as not to come off from the floor member A. You.

Further, the board 4 forming the connecting member is
Since the V-shaped grooves 8 and 9 provided at portions corresponding to the orthogonal symmetry axis can be bent, a good absorbing effect can be obtained even when the floor member is loose due to unevenness of the floor slab.

Further, in this embodiment, since the groove 7 provided on the back surface of the board 4 is fitted to the exposed portion of the leg 2a, 2b, the board 4 is attached to the leg 2a, 2b. 2b
The floor member is more reliably connected than when the floor member is simply placed on the exposed portion. A bendable surface material such as a carpet is provided on the surface of all the floor members connected by the above-mentioned connecting tool, and the access floor is completed.

[0014]

[Effect of the invention] As described above, according to the invention,
The floor members can be connected to each other simply by placing and pressing the connecting tool between the floor members adjacent vertically and horizontally, and the connecting tool after connection can be firmly held so as not to come off from the floor member. .
