Background
The cast-in-situ concrete structure can be divided into two major types according to the construction mode, wherein the cast-in-situ concrete structure needs to support templates on a construction site, tie reinforcing steel bars, pour concrete, maintain and form-remove the concrete under certain conditions, and the like, and the cast-in-situ concrete structure has good integrity and rigidity, but also has the defects of long working time, multiple and complex working procedures, more wet operation, and the like.
For prefabricated assembled structures, the assembled frame structure form is one of the most commonly used structure forms, and the main connecting parts are between beams and columns. The connection modes are numerous, such as post-pouring integral connection, steel bar or embedded part welding connection, bolt connection, prestress splicing, mixed connection among different modes and the like.
The assembled concrete structure refers to a structure system, an external maintenance system, an internal system and the like which are manufactured in advance in factories or construction sites, and scattered prefabricated components are connected into a whole through connection means such as grouting connection of a steel bar sleeve, overlap connection of a steel bar slurry anchor and the like, so that a reliable building structure is formed. Because the fabricated concrete structure has poorer anti-seismic and waterproof properties than the cast-in-place concrete structure, the fabricated structure is in the low valley of the building market for a long time in China. However, with the economic development of China, the labor price is greatly increased, the requirements of China on energy conservation and emission reduction are continuously improved, and the assembled structure gradually gets rid of market valleys. Prefabricated components of the assembled structure can be manufactured and processed in factories, so the assembled structure has high quality and high industrialization level, labor force can be effectively saved under the condition that labor force price is greatly increased nowadays, so that engineering cost is reduced, and the assembled structure can effectively avoid dust raising on a construction site, reduce wet operation on the construction site, save materials and reduce construction waste. Fabricated structures have been widely used for many years in many countries of high intensity earthquakes, particularly countries with developed levels of construction technology, such as the united states, japan, europe, etc.
The prefabricated structure has poor anti-seismic and waterproof capabilities compared with the cast-in-place concrete structure because the prefabricated parts of the prefabricated structure are all formed by connecting joints, and compared with the traditional building method, the prefabricated structure has more connecting interfaces and joints. According to researches, the failure mode of the assembled structure in the earthquake mainly comprises the failure of the connection of the components, and the failure of the precast beams and the precast columns is smaller, so that the connecting piece in the assembled concrete structure is a weak link of the assembled structure.
