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 construction quality.
Description
Technical field [0001] The invention relates to a construction method in an electromechanical installation project in the construction industry, belonging to the technical field of pipeline pre-embedding of a building construction electromechanical installation system, and in particular to a complex electromechanical pipeline pre-embedding construction technology in a narrow space in a cast-in-place beamless hollow floor. Background technique [0002] With the continuous development of science and technology, modern architecture requires continuous improvement of traditional structural forms and construction methods to adapt to the development of the times for the diversity of residential and public building development. The cast-in-place beamless hollow floor is a new structural technology developed in China in recent years. It has the advantages of reducing its own weight, reducing seismic effects, increasing the rigidity of the floor, and the sound insulation of the floor, whi...
