Description
Technical field
The present invention is precast concrete exterior wall cladding and its connection in a kind of design and construction for structural engineering
Structure, belongs to the innovative technology of architectural engineering prefabricated concrete structure technical field.
Background technology
Precast concrete exterior wall cladding is widely used in prefabricated concrete structure as fender member, and being must be indispensable
Prefabricated components, it is one of the key factor for influenceing overall structure security with the connection between agent structure component.At present
The precast facade hanging plate connection species that China's relevant design specification is provided is less.Can be used as assembled steel tendon concrete frame structure
The general exterior wall cladding and its connected mode of design considerations substantially deposit two kinds of problems：A kind of problem is end node convex under hanging plate,
Or due to built-in fitting form complexity in concrete frame beam, beam section is designed to non-rectangle, so as to influence interior architecture function
Use；Second problem is by the embedded bar that is set along wallboard length direction and cast-in-place mixed between hanging plate and beams of concrete
Solidifying earthwork formula connection so that connection difficulty is big, and work progress is complicated.Therefore need to carry out suitable for prefabricated concrete structure
New precast concrete exterior wall cladding and its research of connection, Novel connection type can be applied to the fabricated construction of prefabricated rate high
In, connection reliability need to be met and construction is convenient, it is easy to field erected requirement.
The content of the invention
It is an object of the invention to provide a kind of attachment structure of precast concrete exterior wall cladding, the present invention solves pre- at present
The problems of concrete exterior wall hanging plate processed and agent structure connected mode.Ensure force path between hanging plate and agent structure
Clearly, connect safe and reliable, and possess based on dry type connection, wet trade amount it is few, connection positioning is adjustable, flexible excellent
Point, to simplify the construction and installation of assembly concrete frame structure exterior wall cladding, and application easy to spread.
The technical scheme is that：The attachment structure of precast concrete exterior wall cladding of the invention, outside precast concrete
Wall hanging plate is connected with prefabricated reinforced concrete composite beam, and wherein the lower end of precast concrete exterior wall cladding passes through connector and this
Floor precast concrete composite beam connect, precast concrete exterior wall cladding both sides by connector respectively with This floor concrete
Native composite beam and upper floor precast concrete composite beam are connected.
Overhanging bracket connector in the present invention in precast concrete exterior wall cladding lower end and precast concrete composite beam
Hold out against to transmit gravity, precast concrete exterior wall cladding both sides are set connecting bolt and connected by connector with precast concrete composite beam
Connect to transmit the horizontal force that hanging plate undertakes, totally two kinds of connected modes realize that precast concrete exterior wall cladding is firm with agent structure
Connection.The advantage of this new Joining Structure is the installation facility of precast concrete exterior wall cladding.This connection installation is in master
Carried out after the completion of body structure construction, it is not necessary to interim wet trade.Precast concrete exterior wall cladding bottom is directly put during execute-in-place
It is placed on the overhanging steel corbel of precast concrete composite beam, it is to avoid installation positioning needs temporary support, and vertical connecting bolt
Setting height(from bottom) it is adjustable, modular level adjustment requirement is preferably met, in the absence of the problem of location difficulty.Additionally, angle steel and supporting company
The reserved connecting hole of connection pad piece is oval connecting hole, adjustment positioning when not only convenient construction is installed, while also ensuring hanging plate
Planar rotate to adapt to the deformation of agent structure.Closed the invention provides a kind of easy construction, simple structure, stress
Reason, convenient and practical precast concrete exterior wall cladding and assembled steel tendon concrete frame structure main body attachment structure.
