FIG. 3 is a perspective view showing a state of being connected by the metal fittings 11, FIG. 3 is an enlarged plan view of the vicinity of a connecting portion by the floor plate connecting metal fitting 11 in FIG. 2, FIG. 4 is a sectional view taken along the line AA in FIG.
It is -B sectional drawing. Floor plate connection fitting 11 of this embodiment
Is manufactured by pressing a steel plate. As shown in FIG. 3, the connecting main body 12 for connecting the adjacent left and right floor plate materials 1 at the position of the slit 4 is connected to the longitudinal direction of the floor plate material (vertical direction in FIG. 3). ) Are provided corresponding to the two slits 4 adjacent to each other, and the central portion of the connecting main body portion 12 is integrally connected by a flat connecting portion 13. As the material for the floor plate connecting metal fitting 11, it is preferable to use normal spring steel at a place of use where rust is not a problem, and stainless steel at a place of use where rust is a problem. Then, each connecting body 12
4, as shown in FIG. 4, an L-shaped engaging portion 15 which engages with the edge 4a of the slit 4 of one adjacent floor plate 1 (the left one in FIG. 4) and the other floor plate 1 The inverted L-shaped engaging portion 16 engaging with the edge 4a of the slit 4 of the plate 1 (the right one in FIG. 4) is integrally connected by a flat plate portion 17, and the L-shaped engaging portion 15 is connected. Is provided with a guide portion 18 which is formed by being bent outward at an end. The tip of the reverse L-shaped engaging portion 16 is slightly upwardly bent in order to ensure engagement with the edge 4a of the slit 4. In this embodiment, a removal hole 18a for inserting a pin portion of a removal tool (not shown) is formed in the guide portion 18. In addition,
As shown in FIG. 9, the slit 4 in the floor plate 1 is a punched hole 6 having a round hole 6b on both sides of a narrow groove 6a.
Of the slit 4 is formed by pushing the periphery (in the range indicated by the two-dot chain line) of the slit 4 into the longitudinal direction.
It becomes a shape bent like a curve like below. The height of the L-shaped or inverted L-shaped engaging portions 15 and 16 of the floor plate connecting metal fitting 11 corresponds to the folded height of the edge 4a. The L shape and the inverted L shape are merely different depending on the viewing direction, but are distinguished for convenience of explanation.
