Description
Technical field
The present invention relates to a kind of anti-buckling support of soap-free emulsion polymeization, and in particular to a kind of anti-buckling support dress of corrugated steel tube concrete
Put.
Background technology
Anti-buckling support is one of energy-dissipating and shock-absorbing damper of building structure, and its principle is by the good axle of interior core metal
To Hysteresis Behavior, substantial amounts of seismic energy is absorbed, so as to mitigate the earthquake response of structure.The anti-buckling branch of traditional concrete filled steel tube
Support is fill concrete or mortar between kernel and outer tube, forms the anti-buckling support of monoblock type, the constraint that its inner core is subject to
It is relatively strong, many ripple buckling failures are not susceptible to, therefore application is relatively broad.But current technology is primarily present following deficiency：1st, it is outer
Enclose steel pipe to be chronically exposed in environment, easily produce corrosion, particularly with outdoor structure and some industrial buildings, even if smearing
Anticorrosive paint, also easily comes off during use, it is therefore desirable to safeguard that once maintenance cost is higher within 3 to five years；2nd, for one
Anti-buckling support in a little higher structures, maintenance difficulties are larger；3rd, lateral expansion after kernel unit compression surrender, can increase and mix
Friction between solidifying soil, so as to cause plug dead, hinders kernel unit to continue to deform and dissipation energy, in order to avoid plug dead as far as possible,
Kernel needs to leave certain pause with concrete, and this results in kernel unit corrosion-vulnerable, reduces its service life；4th, for existing
The anti-buckling support of some concrete filled steel tubes, the effect of contraction of steel pipe itself is stronger, can meet supporting condition, the thickness of required steel pipe
Will not be too thick, and in order to avoid local buckling occurs for the steel pipe of periphery, generally artificially lift wall thickness, add material cost.
In summary, the inner core of the anti-buckling support of existing concrete filled steel tube and the easy corrosion of outer tube and the easy office of steel pipe
The problem of portion's flexing.
The content of the invention
The invention aims to solve the anti-buckling easy corrosion of support of existing concrete filled steel tube, periodic maintenance difficulty
Greatly, the problem of easily local buckling occurs for maintenance cost high and peripheral steel pipe, proposes that a kind of inner core uses the zinc-plated ripple of stainless steel
The anti-buckling support meanss of line concrete filled steel tube.
The technical scheme is that：A kind of anti-buckling support meanss of corrugated steel tube concrete, it includes corrugated steel tube, core
Plate, core plate sleeve pipe and two node connectors, core plate, core plate sleeve pipe and corrugated steel tube are sequentially set with from the inside to the outside, and concrete is poured
Build between core plate sleeve pipe and corrugated steel tube, the two ends of core plate are connected with a node connector respectively.
Further, corrugated steel tube is zinc-plated corrugated steel tube.
Further, node connector includes core plate hinged end and gusset plate connection end, the lower end of core plate hinged end and core
One end welding in plate two ends, the upper end of core plate hinged end is connected with the lower end of gusset plate connection end.
Further, gap coordinates between core plate and core plate sleeve pipe, and fills lubricating layer between core plate and core plate sleeve pipe.
Further, the material of core plate and core plate sleeve pipe is steel.
Further, the shape of cross section of core plate is in-line, I-shaped or cross.
The of the invention and anti-buckling support phase ratio of existing concrete filled steel tube, the present invention has the advantage that：
1st, peripheral zinc-plated corrugated steel tube 1 of the invention has stronger anti-corrosion ability, and service life is usually 50 to 100
Year, can meet major part structure use requirement, for the structure under open-air atmosphere, frequency of maintenance it is higher (general 3 to five years/
It is secondary), and for the higher industrial building of height, maintenance difficulties are higher, therefore using the zinc-plated corrugated steel tube of antirust, can subtract significantly
The cost of few periodic maintenance.
2nd, in order to avoid the steel pipe of periphery local buckling occurs for prior art, generally artificially lifts wall thickness, the present invention is adopted
With corrugated steel tube 1 as constraint element, the rigidity of body itself is higher, it is not necessary to prevent local buckling by increasing wall thickness.
3rd, due to itself having higher plane stiffness, corrugated steel tube 1 itself is used as template, quick construction, and
Swollen modulus problem can be prevented effectively from；
4th, core plate sleeve pipe of the invention its own there is some strength and rigidity, therefore in work progress, can not only protect
Itself glacing flatness is demonstrate,proved, and core plate is played a very good protection, so as to ensure construction quality；
5th, due to corrugated steel tube 1 itself have higher plane stiffness, the making of anti-buckling support of the invention, transport,
During construction and use, it can withstand shocks and collide；
