Connection structure of precast floor slab, precast floor slab system, and bridge structure

摘要

PROBLEM TO BE SOLVED: To provide a precast floor slab connection structure allowing precast floor slabs to be easily connected with each other.SOLUTION: A precast floor slab connection structure 2 connects a first precast floor slab 10 and a second precast floor slab 20, which are formed into tabular shape and disposed in arrangement direction X that intersects a thickness direction Z. The precast floor slab connection structure comprises: a first convexity 15 having first inclined surfaces 15c, 15d, which project from a side face of the first precast floor slab and incline toward one side Z1 in the thickness direction with the closeness to one side Y1 in an intersecting direction Y that intersects in the thickness direction and the arrangement direction; and a second convexity 25 having second inclined surfaces 25c, 25d, which project from a side face of the second precast floor slab and incline along and contact the first inclined surface. Movement of the first convexity and the second convexity in a direction along the first inclined surface is restricted by static frictional force between the first inclined surface and the second inclined surface or a fixing strength applied on the first inclined surface and the second inclined surface.SELECTED DRAWING: Figure 3
