Overlapping assembling integrated basement of beam-free floor system

Abstract

Discloses is an overlapping assembling integrated basement of a beam-free floor system. A basement bottom plate is a full cast-in-place concrete bottom plate or a prefabricated overlapping bottom plate. Basement side walls are prefabricated overlapping sandwich walls. A plurality of cast-in-place columns are arranged in the middle of the basement and provided with column caps. A basement top plate adopts a beam-free overlapping solid floor or a beam-free overlapping hollow floor, minus n layers adopt beam-free overlapping hollow floors or beam-free overlapping solid floors, and n is a natural number. The beam-free overlapping solid floor or the beam-free overlapping hollow floor of the basement top plate, prefabricated overlapping sandwich wall tops of the side walls and the column caps on the cast-in-place columns are connected into a whole through casting in place. The beam-free overlapping hollow floors or the beam-free overlapping solid floors of the minus n layers and the column caps on the cast-in-place columns are connected into a whole through casting in place. The advantages that prefabrication in a factory is good in quality, high in speed, high in efficiency, good in environment protection performance, good in cast-in-place integrity and high in structure strength are given into pull play. Module-free construction on site is realized, the earth volume is small, the cost is low, the construction speed is high, quality is controllable, environment pollution is avoided, and the technical performance is excellent.

Description

technical field [0001] The invention belongs to the technical field of construction engineering, and in particular relates to a superimposed and assembled integral basement of a beamless floor system. Background technique [0002] As we all know, all the basement projects of traditional buildings adopt cast-in-place concrete structures, which requires the excavation of large enough underground foundation pits to ensure large-scale construction such as on-site raw material stacking, concrete transportation, formwork support, pouring, vibration, maintenance, and formwork folding. Therefore, the amount of earth excavation is large and the amount of backfill is also large. Since all work is done on site, all wall panels and roof panels must be equipped with formwork, and the formwork cannot be removed until the concrete has fully reached its strength. Therefore, the demand for formwork and scaffolding is large, the construction period is long, and the labor is large. It is tran...

Problems solved by technology

Since all work is done on site, all wall panels and roof panels must be equipped with formwork, and the formwork cannot be removed until the concrete has fully reached its strength. Therefore, the demand for formwork and scaffolding is large, the construction period is long, and the labor is large. It is transported to the site in bulk, polluting the environment, causing waste of raw materials, high labor costs, and the manual vibrating operation of concrete pouring on site is difficult and demanding, and if the vibration is not solid, there will be hidden dangers of water leakage

In addition, the quality of cast-in-place concrete is uncontrollable, the curing conditions are poor, and the possibility of micro-cracks in the concrete is high. Later, rainwater will leak through micro-cracks, which will affect the quality of the building.
