BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, a step board assembling method of the present invention and a step board connecting member used in the step board assembling method will be described with reference to an illustrated embodiment. here,
FIG. 1 is a perspective view of a tread plate connecting member of the present invention, FIGS. 2 and 3 are views showing a process of connecting tread plates to each other using the tread plate connecting member shown in FIG. 1, and FIG. 4 is a state in which a pair of tread plates are assembled. FIG.

First, the step board connecting member 1 of the present invention is a web (connecting member) for connecting and supporting a pair of pressing plates 2a and 2b facing each other in parallel and the central portions of the pair of pressing plates 2a and 2b. 3 and has a substantially planar shape as a whole. More specifically, the web 3 is composed of a pair of plates 3a and 3b facing each other in a state of being curved outward. It is preferable that the step board connecting member 1 is integrally formed of a relatively hard, elastic and mechanically strong plastic, for example, polypropylene or polyester. Therefore, such a plastic material is used, and the pressing board having an appropriate thickness is used. 2a, 2
When b and the plates 3a and 3b are formed, the pair of plates 3a and 3b exhibit a large repulsive force toward the outside when the curved portion is pressed and deformed toward the inside.

It should be noted that the distance between the pair of pressing plates 2a and 2b should be connected as shown in FIG. 3 when the pair of plates 3a and 3b are pressed inward and brought into close contact with each other when the step plate is assembled. It is set in advance so that both (thickness width) of the frame body 4a with the connecting groove, which is provided to project downward on the peripheral edges of the bottom surfaces of the pair of step plates, can be just fitted between the pair of pressing plates 2a and 2b. .

Next, a method of connecting a pair of step plates using the step plate connecting member 1 will be described. First, as shown in FIG. 4, the tread plate 4 is made of any material such as wood or plastic, and is formed into a plane quadrangle.
A frame 4a is provided so as to project downward along the peripheral edge thereof, and in addition to the four corners thereof, the central portions of the four sides are respectively raised, and the connecting groove 5 is bored in the raised portions of the central portions of the four sides. ing. Therefore, the step board connecting member 1 connects the step boards 4 to each other through the connecting groove 5. In addition,
