UNIT OF MOVABLE JOINT TO FORM WEB OF CONCRETE MATS (VERSIONS) Russian patent published in 2015 - IPC E02B3/12 

FIELD: construction.

SUBSTANCE: group of inventions is related to hydraulic engineering, namely to the means for strengthening the surfaces of various objects of natural or synthetic origin, including the banks and beds of watercourses, surfaces of dams and dikes, as well as underwater lines of pipelines, bridge supports. Besides, the device may find application also in the field of construction. Unit of movable joint for web forming of concrete mats comprises the connecting element and fastenings. Fastenings are embedded into the concrete units of mats. According to the first option of the device, the units are asymmetric in plan and are designed with bevels, forming the cavity in the web. According to the second option of the device, the units are designed with recesses outside the plane of maximum size of the unit in plan, forming the cavity in the web. According to the third option of the device, the units are designed with bevels or recesses in its corner portion, forming the cavity in the web. Connecting element is disposed in the cavity indicated in options of the device, and is connected with fastenings with possibility of unit displacement.

EFFECT: protection of mat fastening against the mechanical damages and manufacturability of creation of movable joint of concrete mats are increased.
