Lay the floor member on the floor board so that the parts gather together, and bring the lower outer surfaces of adjacent leg pieces of the floor member to be joined in the front-back direction into contact or pressure contact with the horizontal regulating pieces, respectively, and in the left-right direction. The outer ends of adjacent leg pieces of the floor members to be joined at the notch positions are brought into contact or pressure contact with the vertical regulation pieces, respectively, and further, the outer ends at the cutout positions are brought into contact with the vertical regulation pieces. It is characterized in that the contact or pressure contact position 1 is provided with a locking recess and a locking protrusion, respectively, which prevent vertical movement of the floor member by locking, and preferably, the floor member is assembled to the connecting member. In order to facilitate this, a locking recess is provided at the outer end of the leg at the notch position, and a locking protrusion is provided on the vertical regulating piece, and the locking recess and the locking protrusion are bent in a dogleg shape. Moreover, the horizontal regulating piece is formed in an outwardly curved shape.

In use, connecting members are first placed at all positions or required positions where the corners of floor members on a floor board made of concrete etc. are joined, and if necessary, these are attached to the floor board. The four floor members are then arranged so as to join each corner of the four floor members on the surface of the connecting member.

Then, the leg piece will touch the floor board at the position of the hole, and
The lower outer surfaces of the leg pieces that are adjacent in the front-rear direction contact or are pressed against the opposing horizontal regulating pieces, so that their movement in the front-rear direction is restricted, and the outer ends of the leg pieces that are adjacent in the left-right direction at the notch position The horizontal movement of the floor member is regulated by contact or pressure contact with the opposing vertical regulating pieces, and the vertical movement of the floor member is inhibited by the locking between the locking recess and the locking protrusion. be done.

Embodiment The following is a detailed explanation of the embodiment of the present application based on the drawings.
．． Figure 3 shows a floor member A, which, as is well known, is placed on the bottom surface of a square floor plate (1) with a side of about 500 m at a position dividing the side into three equal parts. Each part has a cut groove (2), and three leg pieces (3) are hung on the lower surface of each part equally divided by the cut groove (2). has wide legs (4) at the bottom;
A grounding piece (5) for cushioning is fixed to the lower surface. In addition, this leg piece (3) has a cut groove (6 grooves) in its longitudinal direction.
The floorboard (1) is divided into three equal parts, each of which has a trapezoidal cutout (7) that opens at the bottom, and the floorboard (1) is covered with a covering board (such as a carpet). 8)
is fixed.

In the present application, in the floor member configured in this manner, locking recesses (9) recessed in a dogleg shape are provided at each outer end of the notch (7) located on both sides of the leg piece (4) in the longitudinal direction. It is intended to provide

In addition, the connecting member B for fixing the floor member A described above has a horizontally long hole (11)a in the center of a horizontally rectangular substrate (lO) made of a steel plate or a synthetic resin plate, and a vertically long hole (11)a that is continuous at both ends of the horizontally long hole (11)a. A hole (11) consisting of a hole (11) b (If) b (If) b is opened, and the horizontally elongated hole (If) a

, and the front and rear edges of the leg part (4) are curved outwardly by, for example, being cut and raised, and come into contact with, preferably in pressure contact with, the outer surface of the leg part (4).
12), but also the vertically long holes (11)b, (11)(11
) The width between the left and right side edges of b approximately corresponds to the width 12 between the outer ends of the notches (7) that are adjacent in the left-right direction (longitudinal direction of the leg pieces) when the floor member A is joined, and At each side edge of each of the vertically elongated holes (11)b (11)b (11)b, a lock is provided on the outer end surface of the notch (7), for example, by cutting and raising it and curving outward. A locking convex portion (with a doglegged cross section) that locks into the recess (9) to prevent the floor member A from moving up and down.
13) and vertical regulating pieces (14) are respectively provided.
(15) is a reinforcing protrusion formed along the periphery of the hole (11), and (16) is a mounting hole.

Therefore, when using the connecting member B, first place the connecting member B at all positions or required positions where the corner of the floor member on the floor board made of concrete etc. 15), and then arrange the four floor members A so that each corner of the four floor members A is joined on the surface of the connecting member B.

Then, the leg piece (3) comes into contact with the floor board at the position of the extraction hole (11), and the leg piece (3) adjacent to it in the front-rear direction.

The outer surfaces of the legs (4) of (3) abut or press against the opposing lateral regulating pieces (12) to restrict movement in the front-rear direction, and the leg pieces (3) adjacent in the left-right direction, The outer end surfaces of the notches (7) of (3) abut or press against the opposing vertical regulating pieces (14) to restrict movement in the left and right direction, and the locking protrusions in the locking recesses (8) The portion (13) is locked and the vertical movement of the floor member A is restrained.

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, so there is no risk of misalignment or misalignment between the floor members due to work errors or over time.
