The expansion joints can be replaced by bendable concrete link slabs, forming a joint-less multi-span bridge。 这恶劣的耐久性的大来源漏机械伸缩接头在多间距桥梁之间毗邻简单的间距。 伸缩接头可以被可弯的具体链接平板替换,形成一座无接缝的多间距桥梁。 [translate] ...
To provide a prefabricated road expansion joints / load transfer assembly (10), which adapt to the normal expansion and contraction of adjacent concrete slabs (90a, 90b) between, and perpendicular to the shear load transfer, and the surrounding concrete (90) The stress cracks are minimized. ...
The present invention provides expansion joints for a road of such construction that in the joint member securing portions which oppose each other through the medium of an expansion spacing, adjacent upper wavy end face plates each of which is connected with respective lower wavy end face plate ar...
1 where: Se = spacing between expansion joints, in. (mm) wj = width of expansion joint, typically the mortar joint width, in. (mm) ej = percent compressibility of expansion joint material (least of sealant, backer and filler) The expansion joint is typically sized to resemble a mortar ...
Expansion joint (1) for concrete slab formwork system, said joint comprising first and second longitudinal members (2, 3), arranged side by side on the same horizontal plane, and each intended to form an integral part with a ridge upper and horizontal of a concrete slab, the first ...
A part of the gap cross section is wider than the upper gap between the two edges of adjacent slabs or side boundaries. The mould components are made of combustible or readily destroyed material which hold the slabs and their groove cavities free during the placing of concrete. Expanded ...
