| Current situation for China’s economic development will continue at a faster rate of sustained development in the future for a long period of time, the main thrust of the rapid economic development is essential there is the construction industry, the current domestic construction industry is still largely based on extensive based, resulting in a serious waste of resources, lack of modern society should be economies of scale, large number of applications obsolete construction technology, development and progress of modern science and technology play in the construction industry unsatisfactory; sustainable development ideas with the same period of the proposed contrary.Traditional construction Sustainable development is bound to be under the new economic situation is gradually phased out, but the rapid development of economy and infrastructure construction products is bound to produce sustained greater demand. At the same time, the demand for quality of life with the rapid development of science and technology continues to improve, which requires for its own future is even more concerned about the living conditions, a safe, comfortable, full sense of ownership is everyone yearning. High-quality building products in modern society is a huge market, in the face of such a huge, sustained demand and is about to open the construction market, China’s construction industry opportunities and challenges. Proposed construction of buildings for industrial practitioners pointed out a direction of development, seize opportunities, meet challenges, and help the development of China’s construction of industrialization, it is ideal for every building practitioners. Application of steel frame not only effectively increase the stiffness of the laminate but also solve the problem of hanging points precast floor, to facilitate the production, lifting, construction process. Laminate application has two main phases, pre-production stage floor and pouring the whole laminated layer application stage, manufacturing production in the factory of prefabricated part, lifted into the construction site after installation pouring laminated layer, laminate floor in the form of one-way prestressed. To improve the mechanical properties of laminated floor, laminated layer to protect the floor and shear strength, taking into account the performance aspects of the construction, the gap between the bracket and the bottom plate may be disposed transversely of the reinforced, laminated layer may be formed after pouring concrete unidirectional prestressed Two force laminated board. The forms of laminate having a high capacity, stability, ease of construction and excellent economic performance characteristics.In this paper the ZDB prestressed laminated concrete slab theory analysis and design, through the mechanical properties results verify the application of laminated; at the same time, laminated prefabricated part is in the factory production, the production process is complicated, many factors affecting the quality of, so of laminated prefabricated parts have needle on to the static test, by testing the load deflection data and theoretical calculation and comparison, in order to ensure that the precast slabs in construction stage of deflection, crack meet the requirements. Construction industrialization will be building components production site transfer to the factory district, member and its manufacturing process with the traditional process existence big difference, the component quality control requirements with respect to traditional engineering quality requirements more stringent; at the end of this paper, briefly ZDB prestressed laminated concrete slab precast structure pieces of the production process and quality requirements, combined with specific examples of projects and traditional crafts by contrast, further verify the laminated economic benefit and social benefit. |
