COMBINED PNEUMATIC CURB FOR ERECTION OF MONOLITHIC SPANS

摘要

FIELD: construction.SUBSTANCE: combined pneumatic curb for erection of monolithic spans comprises a curb shield made of sheets of elastic material tightly attached to each other along the contour and fixed along the perimeter to a bearing frame. Above elastic sheets, to the bearing frame there is a rigid sheet of rectangular form fixed, being the working deck of the shield. The lower elastic sheet comprises a nozzle for pulling excessive pressure inside a tight structure, the shield rests against sliding stands or crossbars.EFFECT: reduced cost and labour intensiveness of operations when erecting monolithic span structures of buildings and facilities.
