In addition, at the position near the other end, there is provided an interval-maintaining projection (25) projecting outward corresponding to the thickness of the interval-holding piece (22).

A pair of support members (6), (6) thus configured
On the left and right sides of the floor panel (4),
The horizontal pieces (18), (18) are superimposed such that they face each other diagonally to the floor panel (4). Then, in this state, the locking projection (23) is inserted into the locking hole (14), and the lower edge of the locking portion (24) is locked to the lower edge of the locking hole (11), so that the floor The panel (4) and the pair of support members (6), (6) are vertically and horizontally bonded, and the spacing member (22) of each support member (6) is further attached to the upper piece (1). ), The outer surfaces of the front and rear side pieces (1) c, and the respective rotary operation portions (5) a of the leg posts (5) face the corresponding operation holes (9), respectively. The floor member A
As shown in FIG. 2 and FIG. 4, the concrete is designed so that the spacing member (22) and the spacing protrusion (25) are located on the joint surface between the floor members A to form a small spacing. Many are laid on the floorboard finished by. Floor member A on the floorboard
When the horizontal state of the floor panel (4) is adjusted after laying, the operation holes (9), (1)
This is performed by inserting a tool through (7) and (13) and engaging the tool with a turning operation (5) a of the leg support (5) and turning the same.

In this way, the floor member (4) is formed by cutting the four corners of the floor panel obliquely and providing a vertical bent piece (20) having a locking hole (21) on the surface of the cut portion (26). When A is laid on the floorboard, the connecting member (30) for integrally connecting the corners of the floor panels adjacent to each other is made of, for example, a synthetic resin,
As shown in FIG. 7, a hollow body (31) having a square cross section and a side having the same width as the cut portion (26) of the floor panel (4), and a side edge of the body (31) is provided. A lid portion (32) that protrudes and locks on the upper edge of the bent piece (20),
Each side surface of the body portion (31) is composed of a vertical upper portion (31) a and a lower portion (31) b inclined downward from the upper portion, and each lower portion (31) b has an upper edge. Upper part (31) a
Downward U-shaped cut line to protrude more outward (33)
Locking tongues (34) which are loosely cut and raised through are provided.

In use, when the floor member A is laid on the floorboard in the same manner as in the prior art, the cut portion of the floor panel (4) of the four adjacent floor members in the laid state as shown in FIG. (26) forms a rhombic space part a. When the body part (31) is inserted into the space part a with its inclined lower part (31) b down, it is resilient. After the locking tongue piece (34) temporarily intervenes in the cutting line (33), it is restored at the position of the locking hole (21), and as shown in FIG.
Of the supporting member (6) of each floor member A
0) The upper edge of the locking tongue piece (34) is locked in the locking hole (21) while being in contact with the upper edge of each of the four floor members A adjacent to each other.
Are connected to each other by a connecting member (30). In this state, the upper portion (31) a of each outer surface of the body portion (31) matches the surface of the cut portion (26) of the floor panel (4), and the upper surface of the lid portion (32) matches the floor panel (4). ). If, for example, a lifting force is applied to one floor member A in the above, an upward force is applied to the connecting member (30) by the lifting force, but the upper edge of the locking tongue piece (34) is connected to the other floor member. Since the connecting members (30) are locked in the locking holes (21) of A, respectively, the lifting of the connecting member (30) is suppressed, and as a result, the floating of the floor member A is prevented.

On the upper surface of the floor panel (4), a square front panel having a side of 500 mm is stretched, and the edge of the front panel B is formed with a small interval formed between the floor panels (4). At the same time, they are tightly joined at the positions, and the corners of the surface mounting plate B are also stretched on the upper surface of the connecting member (30). Although the above description has been given of a floor member in which the floor panel (4) has a square shape, the floor panel (4)
Is a floor member A 'having an equilateral triangle, as shown in FIG. 9, the interval formed by gathering the cut portions (26)' of the floor panel becomes a regular hexagon, so that the connecting member (30) 'is also formed. Also, the body is formed in a regular hexagonal cross section.

Effect of the Invention As described above, according to the present application, the floor members laid on the floorboard are connected and fixed to each other at the corners thereof, so that there is a gap or misalignment between the floor members due to work errors or over time. Therefore, the appearance of the floor structure can be improved, the floor surface can be made smooth, the smoothness of the floor surface can be obtained, and there is no possibility of damage at the joint position. In addition, it is possible to prevent the floor members from being lifted up, and furthermore, since the floor panels are directly connected to each other, the floor panels can be integrated with each other, so that there is a possibility that a gap between the floor panels is generated, and the floor panels can be locked more reliably. According to the configuration of the fourth aspect, there is an advantage that the insertion of the connecting member into the interval portion is facilitated.
