Description
Technical Field
The utility model relates to a connecting piece specifically is a prefabricated assembled component connection spare.
Background
The connection between prefabricated structures is usually a wet connection or a dry connection. The wet-type connection is characterized in that exposed steel bars reserved by prefabricated components are connected into a whole through post-poured concrete in a steel bar lap joint mode similar to a cast-in-place reinforced concrete structure, and the connection effect is good. The dry connection is realized by reserving a pore passage on the component and mechanically connecting the component by bolts and the like. The recent new grouting sleeve type connection method, in which structural steel bars are connected by high-strength grout, is a further development of the dry type connection method.
The wet connection adopts post-cast concrete, so the integrity of the structure is similar to that of a full cast-in-place concrete structure, the connection effect is better, but the concrete needs to be locally cast, and the construction efficiency is lower. All components need to reserve joint reinforcing steel bars and can only be connected with preset and specific components, so that the flexibility is poor.
The dry-type connection construction speed is high, but the shearing force between the connection surfaces cannot be transmitted through the connection parts, and the shearing force key needs to be added or the structural adhesive needs to be adopted for supplement on the interface. The new grouting sleeve type connection mode in recent years can better overcome the defects of dry connection, but the design characteristics of the grouting sleeve type connection mode can not avoid a large amount of field grouting operation and local concrete pouring, and particularly the grouting quality can seriously affect the connection strength. The problem of poor flexibility also exists in dry-type connection, and the shear key preset at the butt joint position of two components to be connected must correspond to the embedded sleeve and the embedded steel bar, so that highly flexible combination cannot be realized.
