Research On Construction Technology Of Steel Reinforced Concrete Composite Structures

Now, with the continuous development of building technology, more and more high-rise and high-rise buildings going up, the world record height of the building has been renewed, which also contributed to the development and application of a variety of new building structures.Steel concrete composite structures, also known as reinforced concrete structure or steel reinforced concrete structure, is the traditional optimization of reinforced concrete structures and steel combine to form, that is added to the traditional steel reinforced concrete structures, making the two traditional structures advantages to co-exist, while the two complement each other to achieve improved since the major reinforced concrete structure, the lower component interface size Japanese steel shortcomings of poor fire resistance. Overall, the combination of steel reinforced concrete structure with reasonable force, excellent seismic performance of wind, a relatively small component interface size, durability and good fire resistance by many other advantages. However, due to the complexity of its construction process, there is no cross between the sub-project, the construction difficult, is mainly used in a number of large, high-rise buildings. In China, due to a combination of steel reinforced concrete structures and less applied research started late, so this structure is relatively slow development in our country. Currently, the project involves the construction of steel concrete composite structures are mainly large number of experienced qualified construction unit construction. Specification of steel reinforced concrete structure on a combination of mainly "technical regulations combination of steel reinforced concrete structures"(JGJ138-2001) and "Technical Specification for steel reinforced concrete structures"(YB9082-2006).This paper focuses on key structural steel concrete composite construction techniques were studied on pedestal node construction method were discussed; construction beam-column joints of steel and reinforced at the site of the cross made effective and feasible method of construction; of steel reinforced concrete beamsThe different construction processes are described and comparison; clear steps and precautions during the pouring of steel reinforced concrete structure when; but also on the construction site safe and civilized cross multiple types of work proposed requirements.Finally, an example of a project in Guangdong topical application of steel reinforced concrete structures, construction methods and illustrate the use of the above recommendations made in the actual project feasible.This paper discusses the theory and method of combining the actual project, summarized the key construction technology of steel concrete composite structure has a certain practical significance, can be widely applied.
