Abstract
The invention discloses an end head formwork for a T-shaped beam formed by casting moulding, which comprises an end formwork with a T-shaped structure and bosses arranged at one side of the end formwork. The number of the bosses is equal to the number of tensioning steel strands of the T-shaped beam. The bosses and the end formwork corresponding to the bosses are provided with round through holes vertical to the end formwork. In the invention, the end head formwork consisting of the end formwork with the T-shaped structure and the bosses arranged at the one side of the end formwork is adopted. When end head formworks are arranged at both ends of a lateral formwork, the bosses on the end formworks respectively correspond to lower anchor backing plates and are connected with the lower anchor backing plates, so that the T-shaped beam can be cast into the required length in one step; and after the T-shaped beam is tensioned, only concrete which is the same as the cast T-shaped beam needs to be adopted to block off shrinkage pools. For the T-shaped beam cast by the end head formworks, not only are the structure requirement of the T-shaped beam and the requirement on the application of a design load of the T-shaped beam met, but also the secondary casting is avoided, so that the construction process is reduced and the construction cost is reduced.
