STRUCTURE REINFORCED CONCRETE SLAB DISMANTLING METHOD AND LOAD-GRIPPING DEVICE WITH ECCENTRIC FOR ITS IMPLEMENTATION Russian patent published in 2018 - IPC E01D22/00 B66C1/10 

FIELD: construction.

SUBSTANCE: invention relates to the bridges dismantling methods. In the structure reinforced concrete slab dismantling method, first marking the structure horizontal reinforced concrete slab unserviceable section to be dismantled. After that, drilling the estimated number of through symmetrical holes therein. Then, inserting the load gripping devices with eccentric into these holes. Then securing the load gripping devices with eccentric in the plate body so, that the eccentric lower disc locks the reinforced concrete slab lower part, and thee eccentric upper disc fixes the load gripping device hollow cylinder upper edge. After that, installing the slinging loops on each load gripping device with eccentric. Next, inserting the lifting ropes into the slinging loops and stretching them. Then cutting out this section. Then the cut out section is lifted and removed. Load-gripping device with eccentric is made in the form of hollow cylinder, into which eccentric with two disks, upper and lower, is mounted. Eccentric disks diameter does not exceed the hollow cylinder inner diameter. In the hollow cylinder upper part parallel to each other through holes for the slinging loop fastening are made.

EFFECT: disclosed is the bridges dismantling method.
