Description
Technical field
The utility model relates to the connected node of a kind of towering iron tower and transmission of electricity large crossing tower structure, belong to steelframe syndeton technical field.
Background technology
Along with the develop rapidly of power construction, big span, cross over the steel pipe high tower greatly and just be widely used.As Zhoushan and continent networking large crossing tower, Senior Two base reaches 370 meters, is the highest electric power pylon in the world at present.The connected node of its structure is the key of design and manufacturing, and whether it is related to the member transmission internal force smooth and easy reasonable, and crucial effects is played in the safe operation of structure.Especially body of the tower is become the complex node of Po Chu and Duo Gen member intersection, its research is just seemed very necessary.
The node processing method of steel pipe iron tower routine is steel pipe stack welding, and seeing has steel tube body node 1 shown in the accompanying drawing 1 shown in the figure, and periphery is welded with a plurality of steel tube body members 2.Because multitube is overlapping, the complexity that causes component internal force to transmit, problem of stress concentration is outstanding, also is unfavorable for processing simultaneously, and especially the weldquality for the angle point place is difficult to guarantee.Owing to steel ball body structure symmetry, power transmission evenly become a kind of desirable joint form, and avoid steel pipe overlapping by the adjustment steel ball size, can make each primary structure member carry out the transmission of power by spheroid, the line of force is clear, succinct.
For the node processing of steel pipe iron tower, the complex node of especially a plurality of member intersection, utilizing welded hollow steel ball node to carry out transition is more satisfactory scheme.For the hollow steel ball structure, the radius-thickness ratio of design requires between 25～45.General iron tower, because scantling is less, the size of its hollow steel ball node is also smaller, meets this requirement than being easier to.And as networking big crossover tower because scantling is very big in Zhoushan, maximum ball node is of a size of 2000mm, therefore will satisfy above-mentioned radius-thickness ratio requirement, and the spheroid wall thickness is at least 50mm.This will bring a series of technical barrier, as the lamellar tearing problem of slab, the problem of stress concentration in the thick plates, and the problems such as installation difficulty of the too big appearance of single-piece weight, the requirement for restriction that the problem of thickness of slab has exceeded the structural steel design technical specification will bring hidden danger to engineering.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of above-mentioned existence, and provides a kind of simple in structure, can satisfy Structural Design Requirement, applicable to the especially big welded hollow steel ball node of the very big big crossover tower of scantling.
The purpose of this utility model is finished by following technical solution, it comprises one by being welded to connect the steel ball body of a plurality of tubular elements, described steel ball body is the hollow steel ball structure, is provided with the ribs that vertical and horizontal are arranged in this hollow steel ball structure.
Described ribs is arranged in the steel ball body by strengthening the method for gusset by orthogonal test, and described vertical ribs is provided with the edge of a wing.
The wall thickness of described steel ball body is not more than 25mm.
The utility model is owing to the design wall thickness to especially big hollow steel ball, as get 24mm, thereby the situation that can not meet the demands for radius-thickness ratio, the measure of taking longitudinal rib and horizontal ribs are set in spheroid solves, control the generation of cripling in this way, and the planning of ribs adopts the method for orthogonal test to arrange; 181 pairs of hollow ball nodes of 4 node elastoplasticity shell unit shell in the application ANSYS software are set up FEM (finite element) model and are carried out computational analysis, design rational large-scale spherical structure, satisfy force request.
The large hollow ball node welding procedure scheme of big rigidity, the junction of many members is explored and formulated to the utility model, to guarantee the welding quality of ball node, solves bead crack and welding deformation control problem that structural member causes greatly owing to the welding constraint degree.
Large-scale ball node galvanizing by dipping scheme described in the utility model is: offer the complete compliant requirement of the galvanizing quality of guaranteeing large-scale ball node member by rational suspension centre setting, fabrication hole, reduce the zinc consumption simultaneously.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in detail: shown in the accompanying drawing 2, the utility model mainly includes one by being welded to connect the steel ball body 11 of a plurality of tubular elements 12, described steel ball body 11 is the hollow steel ball structure, in this hollow steel ball structure, be provided with the ribs 13,14 that vertical and horizontal are arranged, see shown in the accompanying drawing 3,4.
Described ribs 13,14 is arranged in the steel ball body 11 by strengthening the method for gusset by orthogonal test, and described vertical ribs 13 is provided with the edge of a wing.
The wall thickness of described steel ball body 11 is not more than 25mm.
The utility model is owing to the design wall thickness to especially big hollow steel ball, as get 24mm, thereby the situation that can not meet the demands for radius-thickness ratio, the measure of taking vertical ribs and horizontal ribs are set in spheroid solves, control the generation of cripling in this way, and the planning of stiffening rib adopts the method for orthogonal test to arrange; 181 pairs of hollow ball nodes of 4 node elastoplasticity shell unit shell in the application ANSYS software are set up FEM (finite element) model and are carried out computational analysis, design rational large-scale spherical structure, satisfy force request.
The large hollow ball node welding procedure scheme of big rigidity, the junction of many members is explored and formulated to the utility model, to guarantee the welding quality of ball node, solves bead crack and welding deformation control problem that structural member causes greatly owing to the welding constraint degree.
Large-scale ball node galvanizing by dipping scheme described in the utility model is: offer the complete compliant requirement of the galvanizing quality of guaranteeing large-scale ball node member by rational suspension centre setting, fabrication hole, reduce the zinc consumption simultaneously.
Domestic steel work industry design maximum sphere diameter in the past is generally 25～45 all less than 1000mm by its radius-thickness ratio of steel ball designing requirement.And the maximum sphere diameter of this employing reaches 2000mm, if be not more than 25mm by Code for design of steel structures requirements steel plate thickness, then the radius-thickness ratio of spheroid can't reach above-mentioned requirements, therefore must consider to add in steel ball inside and weld the crisscross floor of putting more energy into.
By the setting of stiffening rib, the stress decrease of spheroid is very fast, satisfies the actual requirement of using fully.In order to reduce the part angle point stress of vertical ribs, we have eliminated the stress concentration phenomenon at angle point place vertically being provided with the edge of a wing on the ribs.
