Description

End anchor box and template for high-rigidity precast beam steel beam Technical Field The utility model belongs to the field of precast beams, and particularly relates to an end anchor box and a template for a steel beam of a high-rigidity precast beam. Background In the industrial production of precast concrete beams, the forming precision of the anchor cavities of the prestressed ends directly determines the reliability of the installation of the anchor and the effectiveness of prestress tensioning. The anchor cavity is used as a jogged carrier of the prestress steel beam and the anchoring system, the geometric tolerance, the inner wall flatness and the axis positioning deviation of the anchor cavity need to meet the strict construction specification, otherwise, the linkage problems of stress transmission path deviation, unbalanced loading of an anchor backing plate, even local structural damage and the like are caused. The prior art can refer to the patent with publication number CN209552019U, which discloses a prefabricated T-shaped beam end-capped template, comprising a template plate body and an anchor box, wherein the anchor box is fixed on one side surface of the template plate body, and the use principle is that the anchor box is positioned in a pouring area of a poured precast beam, so that a groove-shaped anchor hole is formed at the anchor box of the poured precast beam, and the adjacent precast beams are cast in situ and have high connection strength due to the existence of the anchor hole. However, there are problems in that the anchor box is fixed to the form, and can be used only for fixing the size of the anchor pocket, and the anchor box has a relatively low structural strength and a relatively short service life. Disclosure of utility model The utility model provides an end anchor box and a template for a large-rigidity precast beam steel beam, which are used for solving the technical problems mentioned in the background art. The end anchor box and the template for the high-rigidity precast beam steel beam comprise a template plate body and an anchor box, wherein the anchor box comprises a steel box body, an auxiliary pull ring, an internal support rib and an anchor box reserved hole, the steel box body is square and is provided with a blocking plate at one end, the size of one end of the steel box body, provided with the blocking plate, is smaller than that of the other end of the steel box body, a conical shape is formed, the anchor box reserved hole is formed in the blocking plate, the auxiliary pull ring is provided with two outer walls symmetrically fixed on one end, far away from the blocking plate, of the steel box body, the internal support rib is fixed on the inner wall of the steel box body, the template plate body is perpendicular to the length direction of the steel box body, a perforation matched with the outer wall of the steel box body is formed in the template plate body, and the perforation is a conical hole matched with the steel box body.
