2. Description of the Related Art Conventionally, the floor panel corners of this kind of free access floor are fixed in a grid pattern on the concrete foundation floor surface of the building at one side width (length) intervals. After laying a large number of floor panels on the panel support caps of the installed support legs while placing the corners of the four floor panels adjacent to each other, cut out the corners of the adjacent corners in the vertical direction. Through the screw insertion space formed by the corner cutouts, the panel fixing screw is screwed into the panel fixing screw hole formed in the center of the upper surface of the panel support cap and fastened, and the panel pressing plate integrally provided with this fixing screw. Therefore, the surface of each corner portion is pressed directly or through a carpet to be fixedly connected to the supporting leg. However, in the former fixing method in which the surface of the corner portion is directly pressed by the panel pressing plate in the above-mentioned conventional fixing method, the panel pressing plate is hidden by the carpet, and therefore, for example, in a computer installed on the floor. It is difficult to confirm the standing position of the supporting legs (the position of the panel fixing plate) when connecting and fixing the partition walls to the supporting legs that partition office equipment and floors. On the other hand, the latter one, which is pressed through the carpet, solves the former problem, but when fixing the corners of the floor panel by screwing the panel fixing screws into the panel fixing screw holes of the panel support cap, There is a possibility that the carpet may be damaged by friction with the panel pressing plate provided on the panel, or the panel fixing screw may be loosened due to the carpet existing between the panel surface and the panel pressing plate. Therefore, as a method of solving the problems of the former and the latter, a plate facing hole corresponding to the size of the panel pressing plate is opened in the carpet, and the corner surface of the floor panel is directly pressed to fix the corner. It is also possible to make the panel pressing plate visible on the floor without being hidden by the carpet, but the edge of the plate facing hole opened in the carpet is rolled up by the foot of a pedestrian or the like to peel off the carpet. There is a possibility that

[0003]

The present invention has been made in view of such conventional circumstances, and the technical problem to be solved is to support a free access floor constructed by laying carpets. As a fixing structure for the floor panel corners where the standing position of the legs can be confirmed from the floor, the floor panel corners are fixed so that the carpet is not rolled and is flush with the carpet surface. is there.

[Technical Means for Achieving the Object] The technical means taken by the present invention to achieve the above-mentioned object are to adjoin each other on the panel supporting caps of the supporting legs which are erected on the foundation floor surface of the building in a checkered manner. The carpet is notched and opened in such a size that the surface of the corner portion of each floor panel is exposed, and a panel pressing member formed in a size that fits in the opening of the carpet is arranged in the opening. A panel fixing screw is inserted and screwed from the screw insertion hole provided in the member to the panel fixing screw hole of the panel support cap, and the panel pressing member is formed in a flat plate shape about the thickness of the carpet, and the panel is centered on the upper surface. It is characterized in that a head accommodating recess is provided at a depth of about the height of the head of the fixing screw, and a carpet pressing flange is provided at the upper end of the peripheral edge thereof so as to project horizontally in the circumferential direction.

[0005]

According to the above-mentioned technical means of the present invention, the panel pressing member is constituted by the corner cutout portions of the floor panels adjacent to each other on the panel support cap of the support leg through the screw insertion holes. By screwing the panel fixing screw into the panel fixing screw hole of the panel support cap through the screw insertion space, the carpet is accommodated in the opening of the carpet so as to be flush with the surface of the carpet, and the corner of the floor panel is directly pressed to the corner. The portion is connected and fixed to the support leg, and the opening edge of the opening of the carpet is pressed by a carpet pressing flange that horizontally protrudes from the upper end of the peripheral edge.

The floor panel 1 and the carpet 2 are made of a well-known desired material in a flat rectangular shape, and the carpet 2 is attached to the surface of the floor panel 1. The floor panel 1 is laid on the floor simultaneously with the laying of the floor panel 1 to form a floating floor A. Then, the four corners of the carpet 2 that covers the surfaces of the four corners of the floor panel 1 are cut out into a substantially fan-shaped plane so that the four corners of the carpet 2 cover the corners of the four floor panels 1. An opening 5 for accommodating the panel pressing member 4 is formed on the surface of the corner portion when the panel pressing cap 4a is placed and supported adjacent to each other on the panel supporting cap 3a.

The panel pressing member 4 is a panel support cap.
By fixing the panel fixing screws 7 through the panel fixing screw holes 6 of 3a and screwing them together, the surfaces of the corners of the four floor panels 1 are pressed together to fix the corners to the support legs 3. A desired material such as metal or synthetic resin is formed into a circular flat plate having a size that fits in the opening 5 of the carpet 2 and the thickness of the carpet 2, and a panel is formed at the center of the upper surface. A head accommodating recess 4a in which the head 7a fits loosely is formed at a depth approximately equal to the height of the head 7a of the fixing screw 7, and a screw insertion hole 4b through which the lower surface is removed is formed in the center of the bottom of the recess 4a. It is opened, and a carpet pressing flange 4c is horizontally projected in the circumferential direction on the upper end of the peripheral edge of the panel pressing member 4.

The carpet pressing flange 4c presses the rim of the opening 5 of the carpet 2 where the panel pressing member 4 fits flush with the surface of the carpet 2 and the rim is rolled up by the foot of a pedestrian or the like. It is provided so as not to exist, and is provided integrally with the upper surface of the panel pressing member 4 in the circumferential direction at the upper end of the peripheral edge thereof with a desired protruding height.

Incidentally, the panel fixing screw 7 of the present embodiment is equipped with a sliding ring 8 formed of a material having a sliding action such as a resin, and is screwed into the panel fixing screw hole 6 of the panel support cap 3a for rotation. At the time of operation, there is no frictional resistance with the panel pressing member 4, and the pressing member 4 can be firmly screwed into the panel fixing screw hole 6 without rotating. On the upper surface of the panel support cap 3a of the support leg, a flat cross shape is provided between the corner portions of the four floor panels 1 adjacent to each other on the cap 3a except the upper edge portions and between the side surfaces of the corners. Similarly, a step portion 10 for mounting the cushioning material 9 is provided in a projecting shape in the shape of a cross in the same plane, and a fitting projection portion 11 is formed at a desired height from the intersection of the upper surfaces of the step portion 10.

[Effect of the Invention] Since the present invention is constructed as described above,
The following operational effects are achieved. In the opening cut out in the carpet in such a size that the corner surfaces of four floor panels adjacent to each other face each other, a flat plate shape that fits in the opening and corresponds to the thickness of the carpet is formed, and the peripheral edge is formed. The panel pressing member is formed by integrally projecting the carpet pressing flange at the upper end of the part, and the corners of the floor panel are connected and fixed to the supporting legs. Therefore, the panel pressing member is flush with the surface of the carpet. The corner portion of the floor panel is directly pressed down and connected to the support leg by the panel fixing screw, and the carpet opening flange of the carpet is pressed down by the carpet pressing flange at the upper edge of the peripheral edge. Therefore, there is no fear of damaging the carpet or loosening the panel fixing screws as in the past, and the carpet is prevented from being rolled even though the fixing structure allows the standing position of the supporting legs to be confirmed from the floor. The effect is obtained.
