Description
Technical field
The present invention relates to building components and fittings and Architectural Structure Design, and in particular to a kind of assembly being connected to connector based on steel plate
Formula reinforced concrete frame structure.
Background technology
Assembled architecture is built made of assemble in site with prefabricated component component.It is construction side to develop assembled architecture
The major transformation of formula is the important measure for promoting construction industry supply side structural reform, and the energy that is conducive to economize on resources is reduced and applied
Work pollution, to promote labor productivity and quality safety horizontal, may advantageously facilitate construction industry and information-based industrialization depth integration,
It cultivates the new kinetic energy of NPD projects, push neutralizing superfluous production capacity.In recent years, China tries to explore to develop assembled architecture, but construction side
For formula mostly still based on cast in situs, assembled architecture ratio and large-scale degree are relatively low, related with Development of Green Building to want
It asks and advanced mode of construction is compared to also there is a big difference.
Currently, China's assembled architecture has certain basis, some experiences in building technology and demonstration project are had accumulated,
But progress is still relatively slower, also not high in the ratio of new building in assembled architecture, probably 5% or so.Influence assembled
The reason of building is promoted is various, and it is wherein important one side that technology is not perfect.The skill that China's assembled architecture uses
Art is introduced from foreign countries mostly, the technology shortcoming of autonomous innovation.Node is the significant points of building structure, cast-in-situ steel reinforced concrete knot
Structure node good integrity, anti-seismic performance are good.However, node connectivity problem is very prominent when assembled arthitecutral structure component assembly,
Node connection is key technical problem in assembled arthitecutral structure design and work progress.The complexity of construction is not only influenced,
Also determine the overall mechanical properties of structure.
The connection type of assembled arthitecutral structure node is varied, the side of traditional prefabrication node connection
Formula has bracket connect, be welded to connect, is bolted and is connected with rigid nose suspension type.Reinforced bar sleeve grouting connection and reinforcing bar slurry anchor overlap joint connect
It is two kinds of node connection types that China's assembled integral concrete generally uses to connect.Assembled based on both connection types
Building structural element is required to throw away reinforcing bar in Member Lip, by bar connecting together after casting concrete again, belong to wet method
Connection.Still there is wet construction at scene, and technical difficulty is big together by a large amount of bar connecting, it is desirable that high, workload is also big.This
Outside, the reinforcing bar that Member Lip is thrown away is required to be protected in component making, transport, hoisting process, brings inconvenience.By
After-pouring concrete is used in existing assembled monolithic concrete structure node, after structure comes into operation, it is difficult to carry out
It dismantles and assembles again, recycle relatively difficult.Geological process lower part component once destroys, and replaces also relatively more tired
It is difficult.
Reinforced concrete frame structure using beam and column as main stress frame, as basic build by beam, plate, column, wall
If plug connection can directly be carried out between each other by building component, rather than be poured again after being connected with each other by internal reinforcing bar
The mode of concrete is attached, and can be efficiently solved assembled architecture node and be connected this key technology difficulty.In addition, such as
Fruit component itself has integrality, easy to disassemble, helps to realize fabricated construction component and replaces and integrally-built cycle profit
With.
Invention content
The purpose of the present invention is to provide a kind of novel assembled steel tendon concrete frame structures, realize beam, column, basis
It is connect with the mutual plug-in dry method of these building elements of wall, floor and waist slab are taken and be placed on beam, break existing with steel
Component node connection type based on muscle connection.Simplify the connection type of node, reduces the difficulty of construction of node connection, removal
The situ wet operation of superstructure construction, mitigates workload, construction efficiency is improved, to push assembled architecture quick in China
It promotes and applies.
The purpose of the present invention is what is be achieved through the following technical solutions：
General layout Plan：Using reinforced concrete frame structure, structural plan is rectangular or squarish, and is ensured laterally not
Less than 3 across.All Vierendeel girder ways are the same, and all cross-section of frame column sizes are identical.
Component makes：Beam, plate, column, wall, basis are all made of reinforcing bar and concrete material, and when prefabricated processing need not throw away
Reinforcing bar, to the regularity of holding member.Exterior wall uses light partition wall using glass curtain wall, interior wall.Floor uses precast hollow
Plate or reinforced concrete thin plate.Inverted L-shaped section is used except Frame Side Beam end, and T section, beam are used except remaining beam-ends head
Groove is reserved at bottom, and all beam-ends heads section is rectangle.
Steel plate is connected to connector and makes：Steel plate connection connector is welded using mold machine-shaping or by steel plate, tie-beam
Logical crown plate it is reserved be used as hush panel, welding top plate sealing in field is reproduced after beam installation is in place.
Means of structural connection：Basis is using prefabricated rim of a cup basis, and bottom frame column is inserted into rim of a cup basis, after installation is in place
It is filled with pea gravel concreten.Connector is connected between Vierendeel girder and frame column, non-framework beam by steel plate to link together.Floor two
End is taken and is placed on beam, floor does not dock to form plate between groove.Light partition wall upper end is inserted into the reserved groove of top beam bottom, lightweight
Groove between plate is inserted into partition wall lower end.
The beneficial effects of the invention are as follows：
The present invention provides a kind of novel assembled steel tendon concrete frame structures and its node connection type, are connected by steel plate
Plug-in dry method connects between girder and secondary beam between pass joint realization beam column, and floor and waist slab are connected with beam overlap joint, wall
Plate and the embedded connection of beam, eliminate the situ wet operation of superstructure, reduce the technical difficulty of existing wet method connection, improve
Construction efficiency reduces cost；Novel joint connection type is convenient for component removal and re-assemblies, and helps to realize building element and replaces
It changes and is recycled with overall structure；Member Lip does not have to throw away reinforcing bar again, convenient for making, transporting and lift；Similar component way
It is as consistent as possible, improve utilization rate of single solitary building to template；Beam, column are inserted into steel plate and are connected to connector, and steel plate is connected to connector can
To play Confinement effect, to improve the reliability of beam, styletable head, the design requirement of " strong node, weak component " is realized；Exterior wall
Using glass curtain wall or light partition wall, interior wall uses light partition wall, reduces dead load, mitigates geological process, takes into account beauty of architecture
It sees and daylighting demand；Rectangular and squarish is used on architectural plane, and is ensured laterally no less than 3 across helping to realize longitudinal direction
It is almost the same with lateral stiffness, enhance the monolithic space action of building, to improve the anti-seismic performance of frame structure.
The present invention is suitable for tier building, can be used for office building, teaching building, dormitory building and new rural village resident house etc. and builds
It builds, it is widely applicable, it is easy to utilize.
