[Detailed Description of the Invention] Industrial Field of Application The present application is directed to laying a floor member having legs on a floor board made of concrete to form a space for wiring such as communication cables between the floor member and the floor board. Regarding floor structure.

Conventional technology Generally, in a floor structure in which floor members having legs are laid on a floor board made of concrete or the like, and a space for wiring such as communication cables is formed between them, the floor members are placed closely together. Even when laid on a floor board, the floor members may move to some extent over time due to unbalanced loads that are applied to the floor surface during walking or when a trolley is running, causing the floor members to move relative to each other. There is a habit of creating gaps between them, and in order to eliminate this habit, conventionally, the four legs that meet at the intersections were tied together at all the intersection points where the four floor members joined. A connecting member was installed to secure the unit to the floorboard.

Problem to be Solved by the Invention However, according to the conventional configuration, connecting members are arranged at all intersection points where four floor members join, so connecting members are arranged on the floor board. The work was troublesome, the construction work of the floor structure required a lot of effort, the construction cost was high, and it was also extremely inconvenient to change the wiring after construction.

Therefore, the present application improves the above-mentioned defects of the conventional method.

Means for Solving the Problems In order to achieve the above-mentioned object, the present application lays a floor member having legs on a floor panel to form a space for wiring such as communication cables between the floor panel and the floor panel. In a floor structure, connecting members are fixed to the floor board at each intersection point formed by joining four floor members, including the outermost floor member along the wall surface or border of the room that made up the floor structure. , the four legs that gather at their intersections are tied together, and if one of the chambers making up the floor structure is long or the chamber is wide, the connecting member may be used. At all intersection points located on a line connecting at least one set of two parallel opposing lines in a loop-shaped line connecting each of the arranged intersection points, the legs are further connected by a connecting member. It is especially effective when the two parallel lines connected at the middle position are the longest lines in the looped line. When the base plate has columnar legs at each of the four corners, the connecting member stands upward at the four corners of the square hole provided in the base plate and comes into contact with the inner surface of the leg. When the floor member is made up of a plurality of parallel plate-like leg parts each having a notch on the lower surface of the floor plate, the connecting member is a rectangular shape provided on the base plate. Horizontal regulating pieces are provided on the front and rear edges of the cut-out holes, with which the outer surfaces of the legs that are adjacent in the front-rear direction of the floor members that are joined to each other abut, and on the left and right edges of the cut-out holes, the outer surfaces of the legs that are adjacent in the left-right direction of the floor members that are joined to each other are provided. A vertical regulating piece is provided with which the outer end surface of the leg at the notch portion comes into contact.

Then, the line connecting the intersection points of the four legs together forms a loop, that is, the floor members are bound together on the loop-shaped line along the wall or border of the room. This prevents the floor member from moving toward the wall due to an unbalanced load applied to the floor.

In the above, if the chamber has a shape that extends long in one direction or if the chamber is wide, each of the lines connecting the two opposite lines at the longest side in the loop-shaped line The four legs are further tied together by a connecting member at the intersection point.
