摘要：
PROBLEM TO BE SOLVED: To provide a method of reducing a temperature stress at a concrete-placed joint between concrete blocks of a bridge girder.
SOLUTION: The method of reducing a temperature stress at the concrete-placed joint, is implemented at the concrete-placed joint between concrete blocks, where concrete 3 is jointedly placed in order to construct a new concrete block 2 in a manner being connected to an existing concrete block 1, by heating at least one end of the existing concrete block 1, adjacent to the new concrete block 2 to be cured. Specifically the existing concrete block 1 is heated to a predetermined temperature, and thereafter the new concrete 3 for the new concrete block is placed. Alternatively the new concrete 3 for the new concrete block is placed, and thereafter the existing concrete block 1 is heated to the predetermined temperature.

要解决的问题：提供一种降低桥梁混凝土块之间的混凝土浇筑接头处的温度应力的方法。 解决方案：在混凝土浇注接头处降低温度应力的方法是在混凝土块之间的混凝土浇筑接头处实施的，混凝土块3被连接放置，以便构造一个新的混凝土块2 通过加热现有混凝土块1的至少一端，与待固化的新混凝土块2相邻，连接到现有的混凝土块1。 具体地说，将现有的混凝土块1加热到预定温度，然后放置用于新混凝土块的新混凝土3。 或者，放置用于新混凝土块的新混凝土3，然后将现有的混凝土块1加热到预定温度。 版权所有（C）2009，JPO＆INPIT
