The invention provides a construction method for embedding electromechanical pipelines in a cast-in-place beamless hollow slab. The method comprises the following steps : (1) sectionally positioning the embedded pipelines by a snapline, and marking the position of an embedded terminal box on a template; (2) fixing a lower-layer terminal box on a preset position, using a foam plate as a filling material in the terminal box, and tightly packaging the terminal box to prevent concrete entering the terminal box; and (3) connecting a lower-layer pipe and the box, sealing the openings of all the pipelines entering the terminal box by rubber stoppers to prevent concrete blocking the pipelines, fixing the lower-layer pipeline according to designed position and the like, wherein the positions and the shapes of the pipelines are adjusted when the pipelines are crossed in the step of embedding the pipelines so as to embed cross points of the pipelines in spaces among hollow pipes. The construction method for embedding the pipelines solves the problem that the electromechanical pipelines are embedded in overhigh positions, prevents the hollow pipes being perforated and ensures the constructionquality.
Description
technical field [0001] The invention relates to a construction method in an electromechanical installation project in the construction industry, belongs to the technical field of pre-embedded pipelines of electromechanical installation systems in building construction, and in particular relates to the pre-embedded construction technology of complex electromechanical pipelines in a narrow space in a cast-in-place beamless hollow floor slab. Background technique [0002] With the continuous development of science and technology, modern architecture requires the continuous improvement of traditional structural forms and construction methods to adapt to the development of the times for the diversity of residential and public buildings. Cast-in-place beamless hollow-core slab is a new structural technology developed in China in recent years. It has the advantages of reducing self-weight, reducing earthquake action, increasing floor stiffness, and good sound insulation effect of th...
