Assembling type hollow floor system with ribbed beams and core models and construction method of assembling type hollow floor system

Abstract

The invention provides an assembling type hollow floor system with a ribbed beams and a core models and a construction method of the assembling type hollow floor system. The hollow floor system comprises a cast-in-site panel and ribbed prefabricated bottom plates, wherein the cast-in-site panel is connected with the ribbed prefabricated bottom plates; each ribbed prefabricated bottom plate comprises a base plate and a ribbed beam, wherein the base plate and the ribbed beam are integrally formed, and the ribbed beam extends upward from the upper surface of the base plate; each core model used for molding the cast-in-site panel is arranged in a hollow cavity between each base plate and the corresponding ribbed beam; a transversal connecting steel bar, extending from inside to outside of each ribbed prefabricated bottom plate, is arranged on the periphery of each ribbed prefabricated bottom plate; the periphery of each ribbed prefabricated bottom plate is placed on a load-bearing beam or load-bearing wall, and a gap used for pouring for a cast-in-site connecting beam is reserved between every two adjacent ribbed prefabricated bottom plates; and the cast-in-site panel and the cast-in-site connecting beams are molded integrally through cast-in-site and are connected with the ribbed prefabricated bottom plates and the load-bearing beam or the load-bearing wall as a whole. According to the assembling type hollow floor system with the ribbed beams and the core models and the construction method of the assembling type hollow floor system, by adopting the prefabricating and cast-in-site combined method, materials are saved, the structural strength is high, the overall rigidity is good, the construction process is simple, construction efficiency is high, the construction period is short, and construction cost can be reduced efficiently.

Description

technical field [0001] The invention relates to the building construction industry, in particular to an assembled hollow floor with a ribbed beam and a mandrel and a construction method thereof. Background technique [0002] With the improvement of domestic economic level and living standards, people put forward higher requirements for modern buildings in terms of large bays, high headroom, comfort, sound insulation, energy saving and environmental protection, and economical rationality. The beam-slab structure obtained by traditional construction has the characteristics of many primary and secondary beams, poor appearance, sluggish building layout, poor sound insulation, heavy weight, and low space utilization rate, which cannot meet people's needs. Moreover, the construction speed is slow, the on-site workload is very large, and the building construction period is long, which is difficult to meet people's timely demand for houses. Subsequently, the hollow floor technology...

AI Technical Summary

Problems solved by technology

The beam-slab structure obtained by traditional construction has the characteristics of many primary and secondary beams, poor appearance, sluggish building layout, poor sound insulation, heavy weight, and low space utilization, which cannot meet people's needs.

Moreover, the construction speed is slow, the on-site workload is very large, and the building construction period is long, which makes it difficult to meet people's timely demand for houses.

Subsequently, the hollow floor technology appeared, but the hollow floor technology currently used has a relatively thick bottom slab, which requires more concrete, more steel bars, and heavy self-heavy. Therefore, the requirements for the load capacity and stiffness of the beam are high, making the beam The design is also relatively bulky, resulting in increased construction costs of the building

In addition, the construction process of the currently used hollow floor technology is relatively complicated. Although the construction period is shortened compared with the traditional process, it still requires a long construction period, labor intensity is high, construction efficiency is low, construction period is long, and construction cost is high.
