Description
Technical field
The utility model belongs to assembled architecture technical field of construction, and in particular to a kind of steel concrete compound tube is connect with basis
Node structure.
Background technique
The steel concrete compound tube of assembled architecture is transported to construction site after factory makes and is assembled, one layer of bottommost
Connecting joint structure between steel concrete compound tube and basis is the most key, this is related to the stability of assembled architecture entirety.It is existing
There is the foot joint of assembled architecture mainly grout sleeve to be used to connect.Under earlier than typhoon, earthquake load, seam crossing is indulged muscle and is held
It is easily broken because of deforming excessive, the structure of assembled architecture is caused to be destroyed.Grout sleeve is generally used to each sleeve simultaneously
Grouting one by one, seam crossing node construction efficiency is lower.
Utility model content
The utility model provides that a kind of stress equalization, stability is strong, wind resistance to solve shortcoming in the prior art
The strong steel concrete compound tube of shock resistance and foundation connection joint structure.
In order to solve the above technical problems, the utility model adopts the following technical solution: steel concrete compound tube connect section with basis
Point structure, the basis are cast-in-situ steel reinforced concrete basis, and cast-in-situ steel reinforced concrete basis top is provided with horizontal steel plate, water
Plain plate lower surface is welded with the embedded ribs for being embedded in cast-in-situ steel reinforced concrete basic internal；
Steel concrete compound tube includes by being in the steel pipe of rectangular cylindrical structure after two-sided ribbed steel bending, and steel pipe periphery has poured
Outer concrete layer, several tension ribs are provided in steel pipe in the width direction, and cast-in-situ steel reinforced concrete is embedded with upwards in basis
Several anchor bars of steel duct are extend into, every anchor bar is vertically arranged, and anchor bar is in neighbouring steel pipe inner wall
It is evenly arranged, the line of all anchor bars forms rectangular configuration, and the outside of anchor bar is provided with several layers and connects all anchors
Gu the stirrup of reinforcing bar pours in steel pipe and pours steel concrete compound tube, anchor bar, tension rib, stirrup in condensation is integrated
Concrete.
It is welded as a whole between steel pipe lower end periphery and horizontal steel plate upper surface.
Steel pipe lower end periphery is fixedly installed rectangle ring flat-plate, and rectangle ring flat-plate lower surface is flushed with steel pipe lower end, cast in place reinforced bar
External surrounding inside concrete foundation in steel pipe is embedded with stud protruding upward, several installations are offered on rectangle ring flat-plate
Hole, stud are upward through mounting hole, be threaded on stud compress rectangle ring flat-plate fastening nut, rectangle ring flat-plate, stud and
Nut is cast in outer concrete layer.
By adopting the above technical scheme, the outer concrete layer of the steel concrete compound tube in the utility model can be poured in factory,
It can also pour at the scene, inner concrete must pour at the scene.Anchor bar and inner concrete by steel concrete compound tube with it is cast-in-place
Reinforced concrete foundation is securely connected as one, and steel pipe is further made to be welded as a whole or pass through pre-buried with horizontal steel plate
Stud and fastening nut by steel concrete compound tube position.Stirrup plays the role of all anchor bars of connection.
In conclusion the utility model is greatly improved the bonding strength between steel concrete compound tube and basis, wind resistance, antidetonation
Performance is strong, cast-in-place to combine with prefabricated, and convenient for construction, construction efficiency is high, and construction quality can be guaranteed.
