Laminated slab post-pouring joint structure and construction method
The invention discloses a laminated slab post-pouring joint structure and a construction method, and relates to the technical field of building construction. The laminated slab post-pouring seam structure and the construction method specifically comprise the following steps that firstly, surveying and setting out are conducted, a beam or a wall and a post-pouring seam formwork system are erected, and the post-pouring seam formwork system is mainly composed of a steel pipe, square timber, an adjustable jacking, multiple layers of plywood and self-adhesive rubber sealing strips; the self-adhesive rubber sealing strip can be adhered to the template, is good in sealing performance, and can be recycled for multiple times after the template is removed. According to the laminated slab post-pouring joint structure and the construction method, the contact face of the straight section of a traditional prefabricated slab is optimized into a structure with the narrow left portion and the wide right portion, the end of the prefabricated slab and the formwork form a reserved groove, an inverted-T-shaped structure is formed after concrete pouring, the overall shape of the prefabricated slab and a cast-in-place layer is increased, the shape is divided into oblique steps, concrete pouring and vibrating compaction are facilitated, and the model reduces the concrete pressure at the slurry leakage position and reduces the slurry leakage rate.
本发明公开了一种叠合板后浇缝构造及施工方法，涉及建筑施工技术领域。该叠合板后浇缝构造及施工方法，具体操作如下：步骤一：测量放线，搭设梁或墙、后浇缝模板体系，后浇缝模板体系主要由钢管、方木，可调顶托、多层胶合板和自粘橡胶密封条组成；自粘橡胶密封条可粘贴至模板上，密封性较好，且拆模后可多次循环使用。该叠合板后浇缝构造及施工方法，对传统预制板平直段接触面进行优化成左窄右宽的结构，预制板端头与模板形成预留槽，混凝土浇筑后形成一个倒T形结构，增加了预制板与现浇层的整体型，且该造型分斜向台阶，利于混凝土浇筑振捣密实，且该造型减少漏浆处混凝土压力，减少漏浆率。
