Fabricated concrete slab wall structure reinforcing steel bar dodges and is connected T shape node with enhancement

Technical Field

The invention relates to a T-shaped node for avoiding and strengthening connection of a steel bar of an assembled concrete slab wall structure, belonging to the field of assembled concrete structures.

Background

The prefabricated concrete building is a building with a concrete structure designed and built in a field assembly mode, wherein the prefabricated concrete components are mainly produced in a factory. The assembly method of the member generally comprises the steps of on-site post-pouring laminated concrete, steel bar anchoring post-pouring concrete connection and the like, and the steel bar connection can adopt the methods of sleeve grouting connection, welding, mechanical connection, reserved hole lap joint and the like. In the 80 s of the 20 th century, the prefabricated large-plate house popular in China has many hidden dangers and defects influencing the safety and normal use of the structure due to poor structural integrity, leakage, floor slab cracks and the like, and is gradually replaced by a cast-in-place concrete structure. However, with the application of the currently emerging prefabricated concrete structure, especially with the introduction of a plurality of foreign advanced technologies in recent years, a new technology for constructing a native prefabricated concrete structure is gradually formed.

The design and construction technology of the fabricated concrete building is researched from the fifties and sixties of the 20 th century in China, a series of fabricated concrete building systems are formed, and typical building systems comprise a fabricated single-layer industrial factory building system, a fabricated multi-layer frame building system, a fabricated large-plate building system and the like. The application of the fabricated concrete building reaches the full prosperous period in the 80 th of the 20 th century, and a fabricated concrete industrialized building mode integrating design, manufacture, construction and installation is formed in many places in the country, the fabricated concrete building and the masonry building adopting the prefabricated hollow floor slab become two main building systems, and the application popularization rate reaches more than 70%. Because the function and physical performance of the fabricated building have many limitations and defects, the level of the design and the development of the construction technology of the fabricated concrete building in China cannot keep up with the change of social requirements and the development of the construction technology, and the fabricated concrete building is gradually replaced by a full cast-in-place concrete building system in the middle of the 90 s of the 20 th century, so that the fabricated concrete building is widely applied to the fabricated single-layer industrial factory building system at present. Other prefabricated building systems have very few engineering applications. The seismic integrity of the prefabricated structure and the specialized research of design, construction and management are not enough, so that the technical economy is poor. Is the root cause of the long-term stagnation of the prefabricated structure.

The connection node of the fabricated concrete requires higher strength and rigidity, and a large amount of steel bars need to be configured. However, unlike a cast-in-place concrete structure, the hoisting of large and heavy components and parts is difficult, so that the connection and avoidance of various reinforcing steel bars are very critical, otherwise, the field construction is difficult, the working hours are increased, and the construction quality is seriously affected. In addition, the shearing resistance of the connecting node is often seriously insufficient due to the integrity problem of new and old concrete. And because the existence of a large amount of reinforcing bars, it is difficult to set up reasonable shear force groove, and some not only seriously influence production, and the effect is also unsatisfactory.
