As shown in FIG. 11 and FIG. 12, this is the case where an arbitrary number of oblong cylinders b having an inverted mortar-shaped oval hollow are projected on two adjacent sides of a rectangular mat block body a, A substantially water-drop-shaped connecting column c is provided at a position facing two sides of a.

When a plurality of mat block main bodies a ... Are connected and laid on the floor, the long cylinders b .. provided on the two adjacent sides of the main body a are connected at the opposite positions of the two sides of the main body a. It was inserted and connected to the column c.

(Problems to be solved by the invention) However, since the size of the mat block main body a is limited in advance, there are the following drawbacks.

That is, there are cases where pillars and the like project inside the building, corridors and the like are provided at the entrance and exit, and equipment that is difficult to move is installed at the corners of the room.

When a plurality of mat block main bodies a are connected and laid on the floor in such a room, a surplus portion of the mat block main body a is formed at a corner portion of the floor space in the room, or the mat block main body a is formed. There were times when some parts were missing.

Further, when a plurality of mat block main bodies a ... Are connected and laid on the floor, and the mat block main bodies a ... Expand / contract due to the temperature difference between summer and winter, in the above connection structure,
It was not possible to sufficiently absorb the expansion and contraction of the mat block main bodies a ....

As a result, the vicinity of the connecting portion at the edge of the mat block body a ...
There were cases where wrinkles were formed.

The object of this invention is to eliminate the above-mentioned conventional drawbacks. That is, by cutting the side wall of each of the plurality of units forming the unit main body, it is possible to form a connecting shape corresponding to the shape of the floor surface, and to connect the connecting portion including the connecting piece and the connecting hole portion. The structure can sufficiently absorb the expansion and contraction of the unit body due to the temperature difference between cold and warm. Moreover, by forming the side wall in a substantially U-shaped cross section, expansion and contraction due to the temperature difference between the individual units can be sufficiently absorbed by the side wall portion.

Further, the unit flooring is provided in which the connection piece and the connection hole can be easily connected and the connection is not accidentally disconnected.

(Means for Solving the Problems) In order to solve the above problems, the present invention provides a rectangular unit main body in which a plurality of unitary units formed in a lattice shape are integrally connected through a side wall. The side wall has a substantially U-shaped cross-section and its top can be cut off. On the other hand, two side walls adjacent to each other on the outer periphery of the rectangular unit body are outwardly formed into a plurality of hook-shaped parts. A connecting piece is provided so as to project, and a connecting hole portion formed of a lattice hole for connecting the connecting piece is provided inside the other two outer side walls and inside the side wall of each unit unit parallel to the two outer side walls. I was supposed to.

(Operation) Of the unit bodies that are connected to each other, the excess unit unit that matches the shape of the floor surface is removed by cutting the side wall, and the unit unit from which this excess unit unit has been removed is needed. It is connected to the main unit and laid on the floor.

This unit body is connected to the outside of the other unit body by cutting a plurality of hook-shaped connecting pieces protruding outward on the outer wall of one unit body into an arbitrary shape as described above. The unit is connected by inserting it into a connecting hole provided inside the wall or inside the side wall of the unit unit at the cut position in the unit main body.

Since the connecting hole portion is formed of a lattice hole, the connecting state of the connecting piece and the connecting hole portion has a margin to sufficiently absorb the expansion and contraction due to the temperature difference of the temperature of each unit body.

Furthermore, since the side wall has a substantially U-shaped cross section,
Expansion and contraction due to the temperature difference of the temperature of each unit forming the unit body is sufficiently absorbed by this side wall portion.
