On-the-spot splicing field of operation between concrete-filled circular steel tube column and post in structure.
Background technology
In order to advance building industrialization, promulgate " prefabricated concrete structure technical regulation ", and assembling
Formula xoncrete structure has obtained large-scale popularization in engineering practice, but this code does not the most well solve existing
The many problems with concrete curing time length of field wet trade.Pass currently for assembled arthitecutral structure system
The method for designing at bonded position lacks systematic research.On the other hand, traditional reinforced concrete structure by
Serious, material and the shortcoming such as energy resource consumption is high, construction material recoverable rate is low in its environmental pollution,
Do not meet the Architecture Policies of country-driven " be suitable for, economic, green, attractive in appearance ".In order to seek to send out
Opening up novel mode of construction, country promotes building industrialization energetically and promotes assembled arthitecutral structure, pushing structure
The standardization of component, improves versatility and the substitutability of structural elements.Steel-concrete combined structure is due to it
Bearing capacity is high, rigidity big, ductility and anti-seismic performance good, and steel have environmental protection, material recovery profit
Using rate advantages of higher, and the most domestic steel excess production capacity, cost reduces, be applied to multi-rise building,
The Structural Engineering fields such as large-span structure, tall and slender structure, bridge structure and underground structure are with the obvious advantage.Meanwhile,
Steel-concrete combined structure can preferably adapt to modern structure for " light-duty greatly across, prefabrication and assembly construction, rapid construction "
Demand, it is easier to realize " being easy to tear down and reconstruct " and " recoverability " of structure, can meet infant industry makeup
Join the relevant supporting requirement of formula building system.
Concrete filled steel tube is used widely in multi-rise building, but its core concrete typically uses
Cast-in-place form of construction work.It is high that concrete-filled circular steel tube column has compression strength, and plastic property is good, and anti-seismic performance is excellent
Different and lock ring effect is good, it is rated as a kind of high-quality, the high-strength and component of economical rationality.Therefore seek a kind of construction
Speed is fast, the detachable assembling type concrete-filled circular steel tube column of construction material recoverable, has great skill
Art economic benefit and social benefit.
In consideration of it, detachable assembling type circular steel tube concrete post is conducted in-depth research by inventor, then by
This case produces.
Summary of the invention
For above the deficiencies in the prior art, the invention provides a kind of simple structure, anti-seismic performance
Excellent, install convenient and efficient, be easy to tear down and reconstruct, energy-conserving and environment-protective, firm detachable assembling type round steel pipe attractive in appearance
Concrete column and the joining method of post.
The present invention is achieved by the following technical solutions:
A kind of detachable assembling type concrete-filled circular steel tube column, mainly includes upper and lower concrete-filled circular steel tube column, post
Flange connector, 2 semi-circular sheet steel with holes and resistance to plucking auxiliary connection, it is characterised in that resistance to plucking auxiliary connection is by spiral shell
The curved muscle of tightening latch, pad, steel bushing and resistance to plucking forms.
The curved muscle of described resistance to plucking passes through welded and installed to steel bushing afterbody.
Steel bushing and the resistance to plucking curved muscle part of described resistance to plucking auxiliary connection are embedded in upper and lower concrete-filled circular steel tube column.
Described post flange connector circumferentially prepared screw-bolt hole on upper and lower two circular flange dishes, by anti-
Pull out auxiliary connection and upper and lower concrete-filled circular steel tube column is spliced into one.
Described 2 semi-circular sheet steel with holes are by welded and installed to the ring flange of post flange connector；From
Pouring into ungauged regions self-compacting high-strength concrete at the reserved semicircle orifice of semi-circular sheet steel, its strength grade is not less than
Concrete grade in steel core concrete column.
The invention have the benefit that
Compared with prior art, the advantage of the present invention is embodied in:
1, the present invention uses detachable assembling type concrete-filled circular steel tube column, all components all to complete in factory process,
Transport to behind job site, can assembly connection at the construction field (site), decrease Site Welding work and form work engineering,
Ensure that site operation quality, improve building industrialization efficiency of assembling.
2, the present invention is by rationally setting the construction measure of concrete-filled circular steel tube column and post flange connector
Meter, uses resistance to plucking auxiliary connection to splice between concrete-filled circular steel tube column and post, then from semi-circular sheet steel
Preformed hole at be in the milk, the mortar poured into is ungauged regions self-compacting high-strength concrete, with resistance to plucking auxiliary connection formed
Common stress after one entirety so that post-post connect the overall bending resistance of rear part and axial stiffness and bending resistance and
Shear-carrying capacity is not less than splicing shaft.
3, post flange connector and resistance to plucking auxiliary connection it are connected by between concrete-filled circular steel tube column of the present invention and post,
When building structural element occurs the concrete-filled circular steel tube column of a certain degree of destruction such as upside or downside to destroy, this
Time can be pulled out the resistance to plucking bolt in auxiliary connection by dismounting so that upside or the concrete-filled circular steel tube column of downside and post
Flange connector separates, and then realizes the dismounting of concrete-filled circular steel tube column, separates and change.That changes is impaired
Concrete-filled circular steel tube column is recyclable, reinforcing, cycling and reutilization, embodies installation convenient and efficient, is easy to tear down and reconstruct
Facade lighting with environmental protection and energy saving.
