Because the anchor pocket box can move around the loose-leaf shaft 24, the anchor pocket box can adjust the inclination along with the end die according to the shape of the box girder (the anchor pocket box is not moved), after the inclination is adjusted, an anchor pad is added at the gap between the bottom of the barrel 221 and the box girder, and an anchor pad is arranged to treat the end die gap so as to prevent slurry leakage.
The embodiment has the following functions and effects: according to the inclination-adjustable anchor pocket device, due to the anchor pocket box, the anchor pocket box is rotatably arranged on the positioning plate through the hinge lug plate and the hinge shaft, when the angle of a steel strand passing through the bottom of the barrel body of the anchor pocket box changes, the whole anchor pocket box can change the inclination angle relative to the positioning plate around the hinge shaft, so that the inclination of the anchor pocket box relative to the positioning plate (the end part of the box girder) can be adjusted according to the specific condition in construction, and the problems that in the background technology, an end mould is uneconomical and unrealistic to design and manufacture for each curve section and the beam end of the widened section beam in each project are solved.
The invention is suitable for prefabrication construction of small box girders with all curve sections and widening sections, has stronger applicability and universality, and does not need to independently remove one set of end mould for each inclined box girder. In the end die installation process, the inclination of the anchor pocket box relative to the positioning plate is adjusted by rotating the anchor pocket box only according to the inclination of the end part of the small box girder, so that the operation is very convenient, and the precision is high.
Because the number of the loose-leaf shafts is two, one end of each loose-leaf shaft is fixedly connected with the anchor pocket box, and the other end of each loose-leaf shaft penetrates through the through hole of the loose-leaf lug plate to rotate, the anchor pocket box is simple to install due to the arrangement, and the loose-leaf shafts are uniformly stressed and cannot be broken when being prestressed and stretched after rotation.
Further, the bottom of staving is provided with a plurality of centers on the preformed hole that the bottom hole set up, this preformed hole is as the connecting hole when being connected with the anchor backing plate, and such setting has made things convenient for the anchor backing plate that adds in the end mould use to fix.
Still further, wherein, anchor pocket box includes two at least staving, adjacent between the staving contact each other, adjacent also contact each other the outward flange, adjacent the bottom of staving does not contact, and such disjunctor design can simplify the structure.
The cylinder body is a cylinder body with a small opening bottom, and the designed cone shape with the small opening bottom is more convenient in demolding.
The above embodiments are preferred examples of the present invention, and are not intended to limit the scope of the present invention.
