Abstract

With the rapid development of our country’s economic construction, the improvement of people’s living standard. All the big span, space of public and civil building more and more appear, for security structure, space utilization, energy conservation and environmental protection requirements also more and more strong, the traditional cast-in-situ concrete floor system limit bottleneck is becoming more and more obvious. How to make full use of building the mechanical properties of materials with its security and stability, economic efficiency for the premise is nowadays structure engineering personnel place in the face of an important issue. As technology gradually mature and new materials, the appearance of traditional set at the floor and no slab floor characteristics in the integration of cast-in-situ concrete hollow slab began to appear in the engineering application. It use the concept with different shapes of the high molecular materials of thin-wall internal model (round and rectangular, tubular) embedded in concrete board, in a certain direction is arranged, the scene casting concrete hollow slab shape. Cast-in-situ concrete hollow floor structure a concrete consumption structure, light weight, small earthquakes, reduce the floor of a tall, equipment pipe set convenience, save material, sound insulation good insulation effect, reduce the cost of engineering overall advantage by many construction unit and technical personnel’s welcome. In recent years because of cast-in-situ concrete hollow floor structure theory has very mature, for cast-in-situ concrete hollow floor structure for more on the design of the research achievements, the domestic study of production hollow floor internal model unit is more, product type is much also, the scope of the advantages and disadvantages and also has the very big difference. According to different internal model of the hollow floor structure in the engineering example comparison and analysis on less, this led to the lack of specific in practical engineering analysis basis.This paper first introduces cast-in-situ concrete hollow floor structure system design theory, this system at home and abroad of research and analysis to development.Analysis of in-situ cast concrete hollow floor slab floor with the traditional differences between the two systems, through the establishment of several different structural models,after structural design software program calculated contrast structure in the force structure, building on the economic performance differences comprehensive analysis of several structural forms.Summed up the actual project in-situ concrete hollow floor design and construction of some key points and issues for the practical work on the in-situ concrete hollow floor structure system design and application of a relatively simple and practical guidelines.Finally, a practical project for the use of the in-situ hollow floor structure of the program for a summary.
