Expansion joint for concrete paving - consists of hollow profiled piece with grooves along sides and support piece
Реферат: The expansion joint for a concrete consists of a hollow profiled piece n10) with two lengthwise end surfaces (11, 12) which are parallel to and opposite each other, and joined by sides (13, 14) extending at right angles to the surfaces (11, 12). The outer surfaces of the sides (13, 14) have lengthwise grooves (16) along which are preferably sloping. Along the profiled piece (10) are regularly spaced out holes (17) in the sides. A support piece for the profiled piece (10) consists of a right angled riangle with perpendicular sides and bottom support surface. Two projections along one edge of the support piece fit into the holes (17) in the surface (11) of the profiled pipece (10).
