A kind of construction site construction concrete steel structure and construction pouring method

Abstract

The invention discloses a concrete-steel structure and pouring method for construction on a construction site. The concrete-steel structure comprises a foundation raft, and the section of the foundation raft is in a U shape and is splayed outwards gradually from bottom to top. A reinforced concrete base beam is further mounted at the top of the foundation raft. Columnar steel is mounted at the center of the foundation raft. A steel wire layer is arranged outside the columnar steel and is formed by fixedly hinging binding wires together. Extra-column stirrups are further arranged between the columnar steel and the steel wire layer. The reinforced concrete base beam and the columnar steel are connected through a through hole which is formed in the reinforced concrete base beam, and an anchor bolt is mounted in the through hole. A three-dimensional orthogonal structure is adopted, concrete is poured layer by layer during pouring, steel bar structures are connected in an overlap welding mode in the pouring process, and thus the probability that the interiors of the steel bar structures are hindered by concrete latex is further lowered; and all the components supplement one another, the crush resistance and the tension resistance of the whole structure are higher, and a good mechanical property is achieved.

Description

technical field [0001] The invention relates to the technical field of concrete pouring technology, in particular to a construction site construction concrete steel structure and a construction pouring method. Background technique [0002] The structure in which steel bars are arranged in concrete is called concrete steel bar composite structure, which is the most widely used high-rise building concrete structure at present. Its characteristic is that there is a concrete shell outside the steel structure. Because the steel concrete structure has good mechanical properties, it is especially suitable for earthquake areas. Although the steel concrete structure has many advantages compared with the traditional structure, there are still the following points Disadvantages: The traditional reinforced structure node reinforcement structure is more complicated, and the engineering construction is difficult. The connection structure has always been the most difficult problem to solve...

Its characteristic is that there is a concrete shell outside the steel structure. Because the steel concrete structure has good mechanical properties, it is especially suitable for earthquake areas. Although the steel concrete structure has many advantages compared with the traditional structure, there are still the following points Disadvantages: The traditional reinforced structure node reinforcement structure is more complicated, and the engineering construction is difficult. The connection structure has always been the most difficult problem to solve in the composite structure, and further research is needed; there are steel plate structures and steel bars in the column-beam-wall. How to deal with the intersecting process between the steel plate and the steel bar is another construction problem. How to ensure the construction quality of the steel plate and the steel bar; The screening and experimentation required a large amount of engineering; in addition, the components were heavy, there were many cross-operations, and there were many safety hazards in the construction, so targeted safety measures were needed to ensure safe construction; finally, the steel bars were dense, and there were many penetrating structures, which gave The pouring of concrete poses great difficulties
