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 resistance to plucking auxiliary connection is made up of the curved muscle of shank of bolt, pad, steel bushing and resistance to plucking, by the spiral shell in steel bushing Tightening latch is tightened or back-outs, it is achieved the assembly or disassembly of concrete-filled circular steel tube column, and the steel core concrete column disassembled can return Receipts recycle, and can reach the effect of energy-conserving and environment-protective.
Described 2 semi-circular shape steel plates with holes are by welded and installed to the ring flange of post flange connector, semicircular ring Shape steel plate thickness is not less than shaft thickness of steel pipe;Ungauged regions self compacting high strength is poured at the reserved semicircle orifice of semi-circular sheet steel Concrete, its strength grade is not less than the concrete grade in steel core concrete column;The ungauged regions self compacting high strength coagulation poured into Soil and resistance to plucking auxiliary connection be common stress after forming an entirety so that post-post connects the overall bending resistance of rear part, shear-carrying capacity With rigidity higher than splicing shaft, there is excellent anti-seismic performance.
The beneficial effects of the utility model are:
Compared with prior art, advantage of the present utility model is embodied in:
1, this utility model uses detachable assembling type concrete-filled circular steel tube column, and all components all 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, it is ensured that on-the-spot Construction quality, improves building industrialization efficiency of assembling.
2, this utility model is by carrying out appropriate design to the construction measure of concrete-filled circular steel tube column and post flange connector, Use resistance to plucking auxiliary connection to splice between concrete-filled circular steel tube column and post, then fill at the preformed hole of semi-circular shape steel plate Slurry, the mortar poured into is ungauged regions self-compacting high-strength concrete, common stress after forming an entirety with resistance to plucking auxiliary connection so that Post-post connects 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 this utility model concrete-filled circular steel tube column 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, now can be by dismounting Pull out the resistance to plucking bolt in auxiliary connection so that the concrete-filled circular steel tube column of upside or downside separates with post flange connector, Jin Ershi Show the dismounting of concrete-filled circular steel tube column, separate and change.The impaired concrete-filled circular steel tube column changed is recyclable, reinforcing, and circulation is again Utilize, embody installation convenient and efficient, be easy to tear down and reconstruct the facade lighting with environmental protection and energy saving.

Detailed description of the invention
The assembling construction step of above-mentioned concrete-filled circular steel tube column is as follows:
1, except needing at the preformed hole of semi-circular shape steel plate of on-the-spot coupled columns and post connecting portion in addition to grouting, all composition structures Part has all been prefabricated in the factory, and on its center pillar flange connector 3, prepared screw-bolt hole size and spacing should meet detailing requiments.Upper, The internal built-in steel sleeve 10 of lower concrete-filled circular steel tube column 1 and 2 should be corresponding with prepared screw-bolt hole 6 on post flange connector 3 and join Set (shown in Fig. 3 and Fig. 4);
2, post flange connector 3 is placed on lower concrete-filled circular steel tube column 2 and reserves on that face of steel bushing 10 so that post Prepared screw-bolt hole 6 and the hole aligning of steel bushing 10 on flange connector 3, installation 6, to shank of bolt 8 and pad 9, completes lower round steel Pipe concrete column 2 and the splicing of post flange connector 3;Then upper concrete-filled circular steel tube column 1 is repeated above-mentioned installation steps, complete Splicing (shown in Fig. 2 and Fig. 5) between upper and lower concrete-filled circular steel tube column and post flange connector 3 three;
3, semi-circular shape steel plate 4 upper and lower end parts with holes is welded on post flange connector 3 (shown in Fig. 1);
4, being in the milk at the reserved semicircle orifice 5 of wherein side on semi-circular shape steel plate 4, the mortar poured into is that ungauged regions is from close Real high-strength concrete, the reserved semicircle orifice 5 of opposite side for air-out (and if post suffer from fire effect, reserved semicircle orifice 5 Can be used for discharging the steam in post inner concrete), eventually form detachable assembling type concrete-filled circular steel tube column (shown in Fig. 1);
If concrete-filled circular steel tube column 1 or 2 need to be carry out demolition and replacement by 5, first being welded on post flange connector 3 Semi-circular shape steel plate 4 with holes electric welding is excised, and then removes, the mortar poured into before then shank of bolt 8 from steel bushing 10 Back-out the most successively so that concrete-filled circular steel tube column and post flange connector 3 overall separation.Then new round steel pipe is shipped from factory The components such as concrete column, repeat 1~4 installation steps, can complete again assembled (shown in the Fig. 1~5) of concrete-filled circular steel tube column.
Above-described embodiment and diagram the product form of non-limiting this utility model patent and style, any belonging to technology neck The those of ordinary skill in territory is suitably changed what it did or modifies, and all should be regarded as the patent model without departing from this utility model patent Farmland.
