The invention provides an integral prefabrication construction method for a steel bent cap. The method mainly comprises the steps: machining a steel main beam and a steel stand column in a factory, constructing a pier body concrete column, and embedding all pre-embedded parts; pre-embedding a steel plate and a temporary fixing anchor bolt in the concrete column, aligning the steel plate at the bottom of the steel column with the pre-embedded steel plate after the steel structure is mounted in place, fixing the steel column, and hoisting the steel bent cap; then pouring encased concrete, pouring non-shrinkage compensation concrete into the steel column to the bottom of the bent cap, and after the strength of the steel stand column meets the design requirement, carrying out beam erection; hoisting the steel beam and butting the steel beam with the steel stand column; and finally, welding a support for positioning the steel stand column and the steel main beam, removing a steel wire rope and a balance weight are
