Production method of prestressed beam adopting straight steel strands

The invention relates to a production process of a prestressed beam, in particular to a production method of a prestressed beam adopting straight steel strands. The production method of the prestressed beam adopting the straight steel strands comprises the following steps: firstly, arranging a plurality of limiting pieces between two tensioning anchor plates at intervals along the tensioning direction, then fixing the steel strands, placing the steel strands on the corresponding limiting pieces, and then pouring concrete to complete the production of the prestressed beam. The limiting pieces are arranged between the tensioning anchor plates to fix the steel strands, the situation that the steel strands are bent due to concrete when the concrete is poured can be avoided, the quality of the prestressed beam can be guaranteed as much as possible, and therefore the application range of the pre-tensioning method can be widened. And the use of common steel bars is reduced, and the construction cost is saved. And co
