SONG TAO / CHEN LEI / ZHANG JUNLIE / ZHOU JI / SUN JIAN

The invention relates to a floor pipeline reserved hole plugging formwork and a construction method, and belongs to the technical field of building construction. The floor pipeline reserved hole plugging formwork and the construction method aim to solve the problems that a wood formwork is not easy to fix before pouring and a poured floor is uneven after pouring in traditional floor pipeline reserved hole plugging. The floor pipeline reserved hole plugging formwork comprises an outer plate and a fixing core, wherein the outer plate comprises a first half outer plate and a second half outer plate which are connected in a buckled mode, and a flange and a groove are arranged at a connecting seam of the first half outer plate and the second half outer plate in a matched mode; the first half outer plate and the second half outer plate are both provided with supporting tables, the supporting tables of the first half outer plate and the second half outer plate are two platform plates provided with the same semicircular bayonets correspondingly, and the radius of the semicircular bayonets is the same as that of a pipeline of a post-pouring reserved hole. The floor pipeline reserved hole plugging formwork can be applicable to pipelines with various diameters by replacing the fixing core, and the construction quality of secondary concrete pouring can be ensured.

本发明涉及一种楼板管道预留洞封堵模板及施工方法，属于建筑施工技术领域，用于解决传统楼板管道预留洞封堵面临的浇筑前木模不易固定、浇筑后浇楼板面不平的难题。它包括外板和固定芯，外板包括扣接连接的第一半外板、第二半外板，第一半外板和第二半外板连接缝处配套设有凸缘和凹槽；第一半外板、第二半外板均设有托台，第一半外板、第二半外板的托台分别是两个设有相同半圆形卡口的平台板，半圆形卡口的半径与后浇预留洞口的管道的半径相同。通过更换固定芯可适用于各种直径的管道，并能确保二次浇筑混凝土的施工质量。
