Construction method of bent cap

The invention relates to a construction method of a bent cap for bridgework construction. The method comprises the following steps: assembling templates: assembling a bent cap template system on the ground; installing support components: installing brackets on stand columns for supporting the bent cap template system; hoisting the templates: hoisting the bent cap template system above the stand columns and ensuring the bent cap template system to be fixed with the brackets; and disassembling the templates: separating the bent cap template system from the bent cap, wherein the step of assembling the templates and the step of installing the support components are performed in a random order, which are finished before hoisting the templates. The invention has the advantage of reducing work high above the ground. The invention can realize integral hoist in position by finishing the assembly on the ground and without supports, thereby saving input of ambient materials and improving working efficiency of mechanized construction; by adopting small modulus standardized design, the invention can cause the templates to be suitable for construction of complex geometry-shaped components, thereby having long service life, good future economy and high-quality molding concrete surface; and large-stiffness of the templates and high precision of accessories ensure planeness of molding concrete.
