The flexible connecting piece can effectively prevent the out-of-plane displacement of the externally hung plate, can effectively coordinate the construction errors of the embedded parts, and does not restrict the in-plane displacement of the externally hung plate.
The utility model relates to a flexible connecting piece of precast concrete cladding panel comprises external plate subassembly (1), major structure subassembly (3), connecting axle (5), internal thread sleeve (4) and connecting rod (2).
To flexible connectors, compare with current rigid connection spare, when installing cladding panel (6) on major structure (7), two connecting plate of cladding board subassembly (1) are opened there is the perpendicular groove, allow connecting axle (5) to take place vertical displacement, and connecting axle (5) pass the ring of connecting rod (2), and connecting rod (2) can take place free rotation and horizontal displacement for connecting axle (5), ensure free deformation in the cladding board plane, and can effectively solve prefabricated component construction error, and it is very convenient to install and dismantle.
Furthermore, the external hanging plate assembly (1), the main structure assembly (3), the connecting rod (2) and the connecting shaft (5) are processed and manufactured in a factory.
Furthermore, the connection between the external hanging plate assembly (1) and the internal thread sleeve (4) embedded in the external hanging plate is completed before hoisting, and the components are fastened by bolts.
Furthermore, the connection between the externally hung plate component (1) and the connecting shaft (5) and the connection between the main structure component (3) and the connecting rod (2) are assembled when the externally hung plate (6) is installed and are fastened by adopting nuts and gaskets.
The utility model has the advantages that: when the external hanging plate (6) is subjected to wind, earthquake, dead weight, temperature and shrinkage action or the main structure is displaced, the connecting piece can ensure that the external hanging plate (6) and the main structure (7) can be freely deformed in the plane of the external hanging plate, but the displacement outside the plane of the external hanging plate is restrained, so that the stability of the external hanging plate is ensured, and the external hanging plate is prevented from bearing additional load action and changing the force transmission mode of the main structure by the external hanging plate; during installation, the connecting piece can be well adapted to construction errors, and is light and fast.
