It is intended to provide a member.

Means for Solving the Problems In order to achieve the above-mentioned object, the present application regulates the leg outer surface of a leg piece adjacent to the front and rear edges of a floor member to be joined, at the front and rear edges thereof, by forming a hole in the substrate. The horizontal regulating means is provided on the left and right side edges of the hole, and the vertical regulating means for regulating the outer end surface of the notch position of the leg piece adjacent in the left-right direction of the floor member to be joined is provided, and the lateral regulating means is provided. While standing up from the front and rear edges of the punched hole, the upper edge of the punched hole is bent downward, and the leading edge is composed of a restriction piece that presses against the outer surface of the leg portion of the leg piece. Along with standing up, the upper part is bent downward, and the tip is composed of a restricting piece that comes into pressure contact with the outer end face of the cutout position of the leg piece of the leg part, and preferably, the bent upper part of the restricting piece is It has a trapezoidal shape, and the substrate is made of steel plate. Is integrally provided by cutting and raising from the edge of the hole.

Action However, when using, place the base on all positions where the corners of the floor members on the floor made of concrete or the like are joined or at their commercial positions, and place this on the floor when necessary. The floor members are fixed, and then the floor members are arranged so as to join the corners of the four floor members on the substrate surface.

Then, the leg pieces come into contact with the floor at the position of the hole, and the outer side surfaces of the leg portions adjacent to each other in the front-rear direction are pressed against the tips of the lateral regulating pieces that face each other, and the movement in the front-rear direction is regulated. At the same time, the variation in the dimension between the leg outer surfaces of the leg pieces adjacent in the front-rear direction is absorbed by the elasticity held in the bent portion of the restricting piece, and in the notch position of the leg pieces adjacent in the left-right direction. The outer end surfaces of the legs are pressed against the opposing vertical regulation pieces to restrict the movement in the left-right direction, and the variation in the dimension between the cutouts of the leg pieces adjacent in the left-right direction is caused by the bent portion of the regulation piece. It is absorbed by the elasticity it possesses.

In the above, the lateral restriction pieces (3) facing each other in the front and rear,
(3) The bent portion (3) a has a tip interval such that, when the tip joins the floor member A, it comes into pressure contact with the outer surfaces of the leg portions d of the pair of leg pieces c adjacent to each other in the front-rear direction. Is set to be slightly smaller than the distance l ₁ between the outer surfaces of the legs d,
Further, the distance between the tips of the bent portions (4) a of the vertical regulating pieces (4), (4) facing each other on the left and right is set to the left-right direction (the longitudinal direction of the leg pieces) when the tips join the floor member A. ) So that each of the cutout portions g is pressed against the outer end surface of the adjacent cutout portion g.
It is set to be slightly smaller than the distance l ₂ between the outer end faces of.
In the figure, (5) is a reinforcing protrusion formed along the periphery of the hole (2), and (6) is a mounting hole.

In use, the substrate (1) is placed at all positions where the corners of the floor member A on the floor board made of concrete or the like are joined or at required positions thereof, and mounting holes ( 6) is used to fix onto the floor and then the substrate (1)
