Abstract
The utility model discloses a concrete filled steel tube iron tower node structure. The concrete filled steel tube iron tower node structure comprises a concrete filled steel tube structure and node plates; the node plates are welded on the outer side of a concrete filled steel tube wall; anchor bolts are anchored in the concrete corresponding to nodes; the anchor bolts also bear the load of the node plates. The concrete filled steel tube iron tower node structure disclosed by the utility model is high in local deformation resistance, simple in construction mode, high in economical efficiency and convenient to machine.
Description
Technical field
The utility model relates to a kind of concrete filled steel tube steel tower joint structure mode, and specifically a kind of gusset plate or tube wall and concrete are by the joint structure mode of crab-bolt anchoring.
Background technology
Along with the development of work transmission line, there is the variation of matter in the size of steel tower, load, and steel tower is tending towards maximizing, and as the stronger member of supporting capacity, encased structures has started to be applied to electric power line pole tower design.In steel pipe, fill concrete forms after concrete filled steel tubular member, steel tube confinement concrete, the longitudinal cracking can delay its pressurized time, and concrete also can delay steel pipe generation cripling.Bi-material has made up weakness each other mutually, can give full play to strong point separately, thereby make concrete filled steel tubular member have very high supporting capacity, from a large amount of test situation, the supporting capacity of concrete filled steel tubular member is all higher than its steel pipe and the independent bearing capacity sum of core concrete.Concrete filled steel tube can significantly improve the compressive strength of member compared with steel pipe, makes iron tower construction member mainly by tension control, can effectively reduce steel tube section long-pending.Because commercial concrete price is lower, can significantly reduce bar cost reduce in the situation that steel tube section is long-pending, reduce investment outlay.
Because can effectively reducing steel tube section, amasss encased structures, therefore steel pipe often adopts thin-wall steel tube to reduce cost, but thin-wall steel tube Out-of Plane Stiffness is less, the position of comparatively concentrating at this curved beam in node junction, may there is steel pipe partial distortion excessive and make the situation of structural failure, if therefore strengthen the wall thickness of whole steel pipe, can increase construction costs, cause the waste of material.
Utility model content
For the problem of the anti-local distortion ability of concrete filled steel tube steel tower joint structure mode in prior art, the utility model provides a kind of anti-local distortion ability strong, and make is simple, good economy performance, concrete filled steel tube steel tower node structure easy to process.
To achieve these goals, the technical solution adopted in the utility model is: a kind of concrete filled steel tube steel tower node structure, comprise encased structures and gusset plate, described gusset plate is welded on the outside of concrete filled steel tube steel pipe walls, in the concrete corresponding with node, anchoring crab-bolt, this crab-bolt is also born gusset plate load.
Described crab-bolt is also born gusset plate load, and crab-bolt passes steel pipe walls and gusset plate welding
Described crab-bolt is also born gusset plate load, the steel pipe inner wall welding outside crab-bolt and welding node plate.
Beneficial effect: concrete filled steel tube steel tower node structure of the present utility model, anti-local distortion ability is strong, and make is simple, and good economy performance is easy to process.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
As shown in Figure 1, a kind of concrete filled steel tube steel tower node structure, comprises encased structures 3 and gusset plate 1, described gusset plate 1 is welded on the outside of concrete filled steel tube steel pipe walls, in the concrete corresponding with node, anchoring crab-bolt 2, this crab-bolt 2 is also born gusset plate 1 load.
Crab-bolt 2 is also born gusset plate 1 load, and crab-bolt 2 passes steel pipe walls and gusset plate 1 welds
Crab-bolt 2 is also born gusset plate 1 load, and crab-bolt 2 is welded with the steel pipe inner wall outside welding node plate 1.
For the less encased structures 1 of caliber, crab-bolt 2 can be welded on gusset plate 1, again by steel pipe perforate, after crab-bolt 2 is stretched into steel duct, gusset plate and steel pipe walls are welded, then concrete perfusion, crab-bolt 2 and concrete are formed with effective adhesive like this, and the curved beam of Nodes can pass to concrete by crab-bolt, replace tube wall to bear a part of the curved beam, effectively improved the anti-local distortion ability of tube wall.For the larger encased structures of caliber, can, to steel pipe perforate, directly crab-bolt be welded to steel pipe inner wall, concrete perfusion after gusset plate welding, the strength reduction of having avoided like this perforate to cause steel pipe, can reach better anti-local distortion effect.Adopt this joint structure mode to efficiently solve the problem of the anti-local distortion ability of existing concrete filled steel tube steel tower joint structure mode, and make is simple, good economy performance, easy to process.
It is pointed out that and while being directly connected (passing through mutually connection), also can improve by crab-bolt the anti-local distortion ability of Nodes tube wall with supervisor when arm, now crab-bolt and inside pipe wall weld, or weld with the tube wall of perforate, here accompanying drawing no longer.
Crab-bolt 2 can have pier nose, also can be without pier nose, and crab-bolt 2 cross sections can be circular, can be also other arbitrary shapes, as square, hexagon etc.
