CONTINUOUS STRONG SYNTHESIS FORMED BRIDGE PRODUCED USING TEMPERATURE STRESS AND CONSTRUCTION METHOD THEREOF

摘要

PURPOSE: The construction method of a continuous strong synthesis formed bridge is provided to prevent the horizontal crack by generating the oppressed stress on a bottom plate by giving the temperature gradient on a strong beam after/before constructing the bottom plate. CONSTITUTION: The construction method of a continuous strong synthetic formed bridge contains the steps of: establishing a continuous strong beam in every specific time interval; providing the heat source to have the temperature gradient covering the continuous upper/lower part of the strong beam; synthesizing by establishing and curing the bottom plate concrete on the continuous strong beam by removing the artificial temperature gradient by the heat source; compensating the tension stress generated on the concrete bottom plate by an additional dead load and active load by the oppressed stress generated at the same time on the concrete bottom plate and on the synthetic strong beam upper part by removing the artificial temperature gradient formed on the strong beam to reduce the steel reinforcing amount, to simplify the production process.
