Study On Technology Ang Economic Anaysis Of The Cbm Cast-in-situ Reinforced Concrete Hollow Slab With Hidden Flat Beam

The appearance and application of cast-in-situ concrete hollow floor structure has become an important part of the development of concrete slab form, and possesses the characteristics of saving energy, materials also complied with national take a new road of new urbanization development trend of green building, which has a broad space of application. This paper studies the CBM cast-in-situ concrete flat beam hollow floor structure is a new type hollow floor structure, is in the cast-in-place reinforced concrete floor according to certain rules to put a certain number of CBM internal model, then cast model formed hollow concrete floor. Now put into use in many building engineering, and achieved good economic and social benefits.The CBM reinforced concrete shallow-beam floor is in the initial stage, the domestic related literature focuses on the structure design principle of CBM cast-in-place reinforced concrete hollow slab with hidden flat beam, and the depth of the economic and technical point of view is comparatively scarce, compared with the application in practical engineering also has the very big disparity, construction technology is not mature, In this paper, the material properties through the induction and analysis of CBM cast-in-place reinforced concrete hollow slab with hidden flat beam structure principle, structural features and internal mold products, and compared with other types of slabs, summed up the characteristics and advantages of CBM cast-in-situ reinforced concrete flat slab of. Cast-in-situ concrete hollow floor; through engineering examples and data collected, summarized the control the main points of construction technology and construction quality of CBM cast-in-place reinforced concrete hollow slab with hidden flat beam; through CBM cast-in-situ reinforced concrete hollow slab with hidden flat beam in different types of buildings in the application of practical engineering, extracting large amounts of data and test data, analysis and comparison of technical and economic indexes and general structure, analyzes and induces the best CBM range of cast-in-place reinforced concrete flat. Cast-in-situ concrete hollow floor, provides the reference for the development and application of CBM cast-in-place reinforced concrete hollow slab with hidden flat beam technology.
