DEVICE FOR HEATING OF MONOLITHED JOINTS DURING CONSTRUCTION OF BUILDINGS WITH PRECAST AND PRECAST-MONOLITHIC FRAME IN WINTER CONDITIONS

摘要

An apparatus for heating zamonolichivaemyh joints in the construction of buildings with prefabricated and prefabricated monolithic frame in winter conditions can be used in construction, for example for warming up the monolithic column with bolt joints and overlap in conditions of negative temperatures. The apparatus comprises a heat-resistant polymeric or metal-pipe with liquid coolant, installed in the joint cavity, with pre-warming surface abutting concrete elements before concreting. Pipes are combined into a single hydraulic system, are embedded in the concrete rendered monolithic joint and connected to the autonomous or centralized power source via connecting pipes dismantled. As the liquid coolant can be used water, or antifreeze or oil. The proposed design for heating zamonolichivaemyh joints; It reduces power consumption when performing heat treatment of concrete and improve the quality of joints of precast concrete in the production of works in the winter. 1 and 4 n.s ZP f-ly, 3 Fig.
