In China, the bridge technology of prefabricating and assembling bridge substructures is widely applied to sea-crossing bridge engineering, and application and popularization in urban bridges are underway. Aiming at the connection structure of the existing prefabricated assembled pier stud (comprising an upright post and a bent cap), the connection structure can be mainly classified into a bonded post-tensioned prestressed bar steel strand (finish-rolled deformed steel bar), steel bars are welded and lapped and adopt wet joint connection, grouting sleeve connection, corrugated pipe connection, slot-in type, socket-and-spigot type, mixed connection and the like, so that the connection between the prefabricated pier studs, the prefabricated pier body and the bent cap and the connection between the prefabricated pier body and a bearing platform are realized, and the assembled contact surface adopts a mortar cushion layer or an epoxy glue joint. The prefabrication and assembly technology is just started in the construction of domestic urban bridges at present and is mostly in a middle-low seismic intensity area of 7 ℃ or below.
The prefabricated assembly technology is applied to the construction of an urban inner bridge, is in a starting stage, particularly in an earthquake-resistant high-intensity area, the construction of a lower structure is more complicated, and a safe, reliable and convenient solution is provided for a prefabricated assembly component (pier stud) and a component connecting structure (bearing platform) according to factors such as bridge type characteristics, construction conditions, engineering environment and the like on components needing systematic research and verification of the prefabricated assembly related technology.
Disclosure of Invention
The invention aims to provide a precast and assembled quick connection structure for a concrete component, which is particularly suitable for an assembled connection structure in an earthquake-resistant high-intensity area and achieves the purposes of higher safety, higher reliability and higher convenience.
In order to achieve the purpose, the technical scheme of the invention is as follows: a precast concrete component is assembled and connected the structure fast in advance, including first precast assembling component and second precast assembling component, characterized by that there is a pouring type slot matched with joint end of the second precast assembling component on the said first precast assembling component, the length of side of circumference of the said pouring type slot is greater than the corresponding length of side of joint end of the second precast assembling component, so as to form the sprue gate around the second precast assembling component after the second precast assembling component positions on the said pouring type slot; the edge of the pouring type slot of the first prefabricated assembly component is provided with a positioning supporting leg, and the outer side of the end face of the second prefabricated assembly component is provided with a corresponding positioning supporting leg, so that matching positioning between the components is more accurate.
Further, the first prefabricated component of assembling is the cushion cap, and the second prefabricated component of assembling is the pier stud, the pier stud bottom is equipped with the reservation reinforcing bar, the pier stud bottom is reserved the reinforcing bar and is inserted in the pouring type slot.
The first prefabricated assembling component is provided with the pouring type slot, so that the prefabricated assembling component is more effective and economical. The pouring type slot is an open type slot, a grouting pipe is not needed, the traditional construction process is adopted, concrete is poured on the spot, the quality of a connection structure is guaranteed, extra construction equipment is not needed, and the economical efficiency is good.
The positioning supporting legs are arranged at the corresponding positions of the connecting components, so that the fixing device is more stable and convenient. If the bottom of the pier column and the top of the corresponding bearing platform are additionally provided with the supporting leg structure, the matching and positioning among the components can be more accurate, namely, the pier column is located on the supporting leg at the top of the corresponding bearing platform, and the pier column is more stable.
After the second prefabricated assembly component is inserted into the pouring type slot of the first prefabricated assembly component, a pouring type slot pouring port is formed in the edge of the second prefabricated assembly component, and the second prefabricated assembly component is suitable for pouring various concrete products and is more operation and economical. The pouring type slot is an open type slot, and various appropriate concrete products can be poured according to the comprehensive requirements of connection (such as insertion of reserved steel bars of a pier column).
The invention overcomes the defects of the existing prefabricated assembly components, such as pier stud and bearing platform connecting structure, has more advantages in the aspects of reliability, safety, economy and operability, can meet the effects of safer, more reliable and more convenient connection of the prefabricated assembly components without adopting complex auxiliary components or materials, and is suitable for pouring various concrete products to form reliable connection.
