Title:
An expansion joint installation method for concrete crack guidance, and its device
Document Type and Number:
Japanese Patent JP6217954
Kind Code:
B2
Abstract:
The present invention relates to a method for installing a crack inducing expansion joint filler when placing concrete so as to reduce cracks generated during concrete construction, and an apparatus therefor and, more particularly, to a method for installing a concrete crack inducing expansion joint filler and an apparatus therefor which can vertically install and fix a plurality of fixed rod shafts on a bottom surface, place concrete, and then fit connection means to the fixed rod shafts while connecting and installing a joint filler member, having a cover means which can be attached and detached between the connection means, before the concrete is cured. Thus, since it is possible to install the joint filler member at the same time as placing the concrete on the bottom surface the method and apparatus can significantly reduce the concrete construction period and also cause that cracks generated by the joint filler during concrete curing can be reduced to a minimum, thereby increasing concrete durability and enhancing construction efficiency.
