Anchor sealing structure at beam end of prestressed box beam and construction method of anchor sealing structure
The invention relates to a prestress box girder end anchor sealing structure and a construction method thereof, and the main technical scheme is that the prestress box girder end anchor sealing structure comprises a box girder, an embedded pipe, an end plate, a bottom template, a side template and a prestress applying assembly; the upper portion of the beam end of the box beam is provided with a protruding part. The embedded pipe is vertically arranged in the protruding part, two vertical partition plates are installed on the embedded pipe, a cavity between the partition plates and the inner wall of the embedded pipe is a first pouring channel, a cavity between the two partition plates is a second pouring channel, a cavity between the side formwork and the groove wall of one end of the reserved groove is a first pouring cavity, the first pouring cavity communicates with the first pouring channel, and the second pouring channel communicates with the second pouring channel. The cavity between the two side formworks is a second pouring cavity, the second pouring cavity communicates with the second pouring channel, the prestress applying assembly is located in the second pouring cavity, and the prestress applying assembly applies separation acting force to concrete blocks formed by the two first pouring cavities. The anti-shearing capability of the protruding part can be improved.
本申请涉及一种预应力箱梁梁端封锚结构及其施工方法，其中主要技术方案为一种预应力箱梁梁端封锚结构，其包括箱梁、预埋管、端板、底模板、侧模板和预应力施加组件；箱梁的梁端的上部具有凸出部位；预埋管竖向设置于凸出部位中，预埋管安装有两个竖向隔板，隔板与预埋管内壁之间的腔室为第一浇筑道，两个隔板之间的腔室为第二浇筑道，侧模板与预留槽一端的槽壁之间的腔室为第一浇筑腔，第一浇筑腔与第一浇筑道连通，两个侧模板之间的腔室为第二浇筑腔，第二浇筑腔与第二浇筑道连通，预应力施加组件位于第二浇筑腔，预应力施加组件对两个第一浇筑腔所成型的混凝土块施加相离作用力。本申请能够提高凸出部位的抗剪切能力。
