Preferably, the upper part of the regulating piece is formed into a trapezoidal shape, the substrate is made of a steel plate, and the regulating piece is integrally provided by cutting and raising from the periphery of the hole, and furthermore, the floor member is formed into a trapezoidal shape. If the hole has a square shape, the hole should be formed into a substantially rectangular shape, and a regulating piece should be erected at each end of the hole so as to be perpendicular to the centripetal line. It is formed into a substantially regular hexagonal shape, and a regulating piece is erected at each end thereof so as to be orthogonal to the centripetal line.

In use, substrates are placed on the floor board made of concrete or the like at all positions where the corners of the floor members join, or at the required positions, and if necessary, they are placed on the floor board. Then, the floor member is placed on the substrate surface so that each corner of the floor member is joined.

Then, the pedestal will touch the floorboard at the position of the hole, and
The lower inner surface of each pedestal comes into pressure contact with the leading edge of the corresponding receiving piece, and each pedestal is tied together to restrict movement in the front-back and left-right directions, and due to the elasticity of the bent part of the receiving piece, Dimensional errors between adjacent pillars in the front-rear and left-right directions due to manufacturing and connection errors are absorbed.

Embodiment Example The embodiment of the present application will be described in detail below based on the drawings.A known floor member A connected by the connecting member of the present application has side pieces on the periphery, for example, and has a side of 500 m. A steel floor plate a made of a square top and bottom plate with a corrugated plate interposed between them. The height is adjustable and camps d made of an elastic material that absorbs unevenness are attached to the bottom end of the steel floor plate a, which has a circular cross section. The connecting member of the present invention, which connects the floor members A configured in this way, is made up of vertical pillars C. A substantially square-shaped punching hole (2) whose part is inclined in a direction perpendicular to the diagonal line is provided, and a substantially square punching hole (2) is formed at each corner position of the punching hole (2) by cutting and raising along the corner. While standing up, the trapezoidal upper part is bent downward to form a receiving piece (3) consisting of a vertical part (3)a and a bent part (3)b.
) is provided as an integral part.

The bent part (3)b of this receiving piece (3) is curved in a concave shape so that the central part in the width direction becomes deeper toward the leading edge, and is connected to the inner circumferential surface of the pillar C to the floor member. A matching curve (4) is formed. Furthermore, a V-shaped notch (5) for display purposes is provided at the center of each side of the hole (2). (5)
is a mounting hole.

Therefore, when using the board, place the board at all positions or required positions where the corners of the floor board made of concrete etc. join the floor members, and if necessary, install the board in the mounting holes (5
) to the floor board, and then four floor members A are placed on the floor board from the top surface of the substrate (1) so that their respective corners are joined.

Then, the inner surface of each pedestal C matches the curved part (4) formed on the bent part (3)b of the corresponding receiving piece (3), and the leading edge of the pedestal C matches the curved part (4) formed at the bent part (3)b of the corresponding receiving piece (3), and the leading edge of the pedestal C matches the curved part (4) formed at the bent part (3)b of the corresponding receiving piece (3). The dimensional errors between adjacent pillars that are in pressure contact with the side surface of the land absorption camp d and due to manufacturing and joining errors of the floor member A are absorbed by the elasticity possessed by the bent portion (3) b. Ru. Result 4
The pillars C are bound together by a single connecting member, and the floor members A are tightly joined to each other to restrict movement in the front-rear and left-right directions.

In addition, although the above example illustrates the case of connecting the pillars C of the square-shaped floor member A, when connecting the pillars C that have an equilateral triangular shape and are suspended from each corner of the floor member A', In this case, by connecting six pillars with a single connecting member, in this case, as shown in Fig. 4, the holes (2) are formed into a substantially regular hexagonal shape, and the positions of each corner are A receiving piece (3) is disposed on each of the two sides.

Effects of the Invention As described above, according to the present application, the floor members laid on the floor board are connected and fixed to each other at their corner positions, so there is no possibility of gaps or misalignment between the floor members due to work errors or over time. Therefore, the appearance of the floor structure is improved, the floor surface is smooth, and there is no risk of damage at the joining position, especially on the upper part of the receiving piece. Since the bending part has elasticity, it can sufficiently absorb dimensional errors between the pillars due to manufacturing and joining errors of the floor members, making it easier to connect the floor members, and making it easier to bend the floor members. The leading edge of the leg is bitten into the lower part of the leg, especially the camp for absorbing unevenness.
