Construction method of prefabricated T beam
The invention relates to the field of building construction engineering, and discloses a construction method of a prefabricated T-beam, comprising the following steps: S1, cleaning a bottom die; s2, binding the main reinforcing steel bars; s3, prestressed pipelines and side formworks are installed; s4, concrete is poured; s5, concrete curing; s6, prestress tensioning is conducted; s7, sealing anchor concrete is poured after duct grouting, beam end sealing anchor concrete needs to be poured at the non-continuous beam end before beam mounting, and the difficulty of binding construction of a web reinforcement cage and a top plate reinforcement cage is effectively reduced; the layout difficulty of the built-in guide ring is reduced; the positions of the formwork supporting plate and the T-beam formwork are limited through the formwork supporting frame, and the mounting and positioning accuracy of the T-beam formwork is improved; the mounting and positioning accuracy of the tensioning jack is effectively improved, and the difficulty of on-site prestress tensioning construction is reduced; and the grouting pump body and the air pressure control pump are combined to control the compactness of the plugging mortar and the sleeve grouting body, so that the construction quality of the plugging mortar and the sleeve grouting body can be effectively improved.
本发明涉及建筑施工工程领域，且公开了一种预制T梁的施工方法，包括以下步骤：S1：清理底模；S2：绑扎主钢筋；S3：预应力管道以及侧模安装；S4：浇筑混凝土；S5：混凝土养护；S6：预应力张拉；S7：孔道压浆后浇筑封锚混凝土，对于非连续梁端，上梁前应浇筑梁端封锚混凝土，有效降低了腹板钢筋笼和顶板钢筋笼绑扎施工的难度；降低了内置导向环的布设难度；通过模板撑架限定模板撑板及T梁模板的位置，提高了T梁模板安装定位的准确度；有效提升张拉千斤顶安装定位的准确度，减小了现场预应力张拉施工的难度；组合采用压浆泵体和气压控制泵控制封堵砂浆和套管注浆体的密实度，可有效提升封堵砂浆和套管注浆体的施工质量。
