On-site construction method of fabricated building prefabricated laminated slab
The invention discloses an on-site construction method for a prefabricated laminated slab of a fabricated building, which comprises the following steps of: firstly, binding reinforcing steel bars and erecting a formwork for vertical components and the like of the building, paving a floor beam and a floor slab formwork, and setting the width of a formwork strip at the bottom of the prefabricated laminated slab close to a cast-in-place wall or beam part and a cast-in-place slab strip part; a layer of formwork is additionally laid on formwork strips of the cast-in-place slab strip and fixed, leakage-stopping rubber strips are pasted, reinforced back ridge battens are arranged, steel pipes are arranged in the vertical direction of the back ridge battens for reinforcement, wedge-shaped wood blocks are stuffed between the formwork strips in the middle area of the cast-in-place slab strip and the back ridge battens for reinforcement, and prefabricated laminated slabs are installed and adjusted in place; binding cast-in-place slab strip reinforcing steel bars, installing pipeline embedded parts and edge sealing formworks, performing concrete pouring, performing mold removal after maintenance, and forming the floor ceiling with the middle part of the cast-in-place slab strip being slightly concave inwards after mold removal. According to the method, an existing supporting mode of a cast-in-place slab strip formwork is not changed, slurry leakage, formwork expansion and downwarping of the cast-in-place slab strip are reduced, and follow-up decoration construction of a floor ceiling is facilitated.
本发明公开了一种装配式建筑预制叠合板的现场施工方法，本方法首先对建筑竖向构件等绑扎钢筋并支模，铺设楼板梁及楼层板模板，设定预制叠合板底部靠近现浇墙或梁部位以及现浇板带部位的模板条宽度，在现浇板带的模板条上再加铺一层模板并固定，粘贴止漏胶条，设置加固的背楞木方，背楞木方的垂直方向设置钢管进行加固，在现浇板带中部区域的模板条与背楞木方之间塞入楔形木块进行加固，安装预制叠合板并调整就位，绑扎现浇板带钢筋，安装管线预埋件和封边模板，进行混凝土浇注，经养护后拆模，拆模后形成现浇板带中部向内微凹造型的楼板顶棚。本方法不改变现有现浇板带模板的支设方式，减少现浇板带漏浆涨模及下挠，方便楼板顶棚后续装饰装修施工。
