Superimposed assembled integral type basement of girderless hollow floor slab system

Abstract

The invention relates to a superimposed assembled integral type basement of a girderless hollow floor slab system. A basement base plate is a full cast-in-situ concrete base plate or a prefabricated superimposed base plate, a basement sidewall is a prefabricated superimposed sandwich wall, a plurality of cast-in-situ columns are arranged in the middle of the basement, the cast-in-situ columns are provided with column caps, the top slab of the basement and negative n floors adopt girderless superimposed hollow floor slabs, where n is a natural number, and the girderless superimposed hollow floor slabs are connected into a whole with the top of the prefabricated superimposed sandwich wall and the column caps of the cast-in-situ columns in a cast-in-situ manner. The superimposed assembled integral type basement of the girderless hollow floor slab system fully exerts the advantages of prefabrication such as good quality, high speed, high efficiency and good environmental performance and the advantages of the cast-in-situ such as good integrality and high structural strength and overcomes the disadvantages of the prefabrication and the cast-in-situ, the advantages are enhanced while the disadvantages are avoided, field modular construction is realized, earthwork volume is small, labour cost and material cost are low, construction speed is high, quality can be controlled, environmental pollution is not produced, and 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 hollow 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 ...

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.
