Grouting reversed-sequence construction method for fabricated vertical component
The invention discloses a grouting reversed-sequence construction method for a fabricated vertical component, and relates to the technical field of fabricated concrete construction. The grouting reversed-sequence construction method for the fabricated vertical component carries out hoisting construction of a multilayer vertical component on a multilayer building according to the number of layers; the grouting reversed-sequence construction method for the fabricated vertical component comprises the steps of S1, carrying out prefabricated outer wall construction, formwork installation, frame body erection, lower reinforcing steel bar binding of slab joints, water and electricity pipeline pre-burying, laminated slab installation and upper reinforcing steel bar binding and concrete pouring on the first layer of the building; S2, carrying out construction of subsequent layers of the building in sequence according to the construction sequence in the step 1, carrying out grouting construction on the first layer of prefabricated outer wall when construction of the third layer of a prefabricated outer wall is carried out, and reserving grouting materials to maintain test blocks under the same conditions; and S3, dismantling a temporary inclined support of an external wall board according to the sequence from bottom to top after concrete pouring and tamping of the upper two layers of cast-in-place areas and the board face of the building are completed and after the strength of concrete meets the design and specification requirements and the compressive strength of the test block maintained under the same condition of the grouting materials reaches 35N/mm < 2 >.
本发明公开一种装配式竖向构件注浆逆序施工方法，涉及装配式混凝土施工技术领域；针对多层建筑，按照层数进行多层竖向构件吊装施工，步骤1：针对建筑第一层，进行预制外墙施工，进行模板安装，进行架体搭设，进行板缝下部钢筋绑扎，水电管线预埋，进行叠合板安装及上部钢筋绑扎，浇筑混凝土，步骤2：按照步骤1的施工顺序依次进行建筑后续层数的施工，并在第三层进行预制外墙施工时，对第一层预制外墙进行灌浆施工，并留置灌浆料同条件养护试块，步骤3：按照从下向上次序，等待建筑上两层现浇区和板面浇捣混凝土完成，混凝土强度达到设计、规范要求且灌浆料同条件养护试块抗压强度达到35N/mm2后，拆除外墙板临时斜支撑。
