Abstract
A steel tower is composed of angle bars and round pipes. The joint portion of the angle bar and the round pipe is equipped with a connecting device, and the angle bar and a butt joint nozzle are connected by the connecting device. The steel tower with the design has simple structure and clear power transmission, and simultaneously the steel tower can reach larger bearing capacity of the tower compared with that which has the same capacity of steel consumption.
Description
Technical field
The utility model relates to a kind of iron tower, is specifically related to a kind of iron tower of being made up of by linkage pipe and angle steel.
Background technology
There are weak axle Y-Y in the iron tower that adopts angle steel to constitute, angle cross section itself, have reduced its stable bearing capacity, thus at big corner, adopt pure angle steel structure when crossing over greatly, will make complex structure, the steel consumption increase, difficulty of processing is multiplied; The iron tower that adopts pipe to constitute, under the situation that section area equates, the radius of gyration of pipe is bigger by about 20% than angle steel, and there are shortcomings such as the specification kind is limited, price height in the steel pipe section bar, the joint structure complexity that connects between the while steel pipe, processing efficient is low.In order to satisfy the designing requirement under various environment, the various condition, the design of iron tower is tending towards variation, the combining structure of multiple material occurred, and the combination of angle steel and pipe is exactly wherein a kind of.
Summary of the invention
The utility model is at the existing in prior technology shortcoming, a kind of simple in structure, consumptive material is few, bearing capacity is bigger iron tower design technology project is provided, use the better transition of implementation structure of iron tower of this design, can not cause the too fat to move huge of iron tower profile.
The utility model is realized by following technical measures: the body of the tower of this iron tower and tower head are made of angle steel and pipe, and there is linkage angle steel and pipe junction, and this device is formed by connecting by connecting angle and butt joint.Adopt the iron tower of this design simple in structure, power transmission is clear, and the iron tower supporting capacity that equal steel quantity consumption can be realized is bigger.
Butt joint is socketed to form by pipe by two flanges, and two flange opposite sides all are welded with junction plate and stiffener, and are welded with the arc stiffener between junction plate and pipe.Connecting angle is welded by flange and angle steel, and flange and angle steel all are welded with junction plate and stiffener, and is welded with the arc stiffener between angle steel and junction plate.The structure design of joint is oversimplified, and junction plate uses as stiffener, not only as the transition point of main material, also provides link position for the iron tower internal construction.Connecting angle is connected by bolt with angle steel Baogang, and is detachable, so can repeatedly use.
Butt joint also can be the single flange of atresia, and weld with connecting angle and pipe respectively these flange both sides, and these flange both sides all are welded with junction plate and stiffener.Though this structure becomes rigid joint, can effectively reduce malformation, also can reduce supporting capacity simultaneously because of the welding manner of pipe and blank flange.
Butt joint generally is positioned at iron tower orlop cross-arm place, is in load to the original position that the iron tower bending moment increases rapidly, has reduced the appearance and size of iron tower, has optimized force structure, and the usefulness of angle steel and pipe is fully played, and effectively reduces steel consumption.
Because of the difference of material, in view of the particularity that two kinds of materials connect, butt joint flange and angle steel flange connecting hole are not five equilibrium distribution.Overlap with flange hole in the time of can avoiding angle steel to weld like this with flange.
Butt joint perpendicular to horizontal plane, can make joint oversimplify with cross-arm type of attachment, the form of structure on top with top.
From the above mentioned, adopt this programme not only can guarantee the steadiness and the reliability of iron tower, and linkage do not depend on iron tower main material as link independently, as long as physical dimension is identical, the iron tower that main material specification is close all can be realized general.

The specific embodiment
For clearly demonstrating the technical characterstic of this programme,, and, this programme is set forth in conjunction with its accompanying drawing below by a specific embodiment.By shown in Figure 1, this iron tower is made of angle steel and pipe, and there is linkage angle steel and pipe junction.This linkage comprises connecting angle and butt joint.Connecting angle is welded by flange 12 and angle steel 18, during welding with the angle steel back-off.Flange 12 and angle steel 18 all are welded with junction plate 10 and stiffener 11 simultaneously, and are welded with arc stiffener 9 between angle steel and junction plate, need guarantee weld bead height during welding, do not allow to carry out weld seam and polish processing, and junction plate 10 can be connected with the oblique material 3 of body of the tower.The angle steel 18 of connecting angle one side is connected with angle steel master material 1 by angle steel Baogang 2.Butt joint is socketed to form by pipe 13 by two flanges 14,19, and two flange 14,19 opposite sides all are welded with junction plate 15 and stiffener 20, and are welded with arc stiffener 16 between junction plate and pipe.Butt joint is fixedlyed connected by bolt mode or welding manner with tube flange 17 with connecting angle flange 12, and is connected with each relevant portion of iron tower by bolt.Junction plate 10, the 15 double stiffeners of doing use in the linkage.Connecting angle is connected by bolt with angle steel Baogang, and is detachable, so can repeatedly use.
Butt joint also can change the single flange of atresia into, direct and connecting angle and pipe welding.
Connecting angle flange 12 and butt joint flange 19 connecting holes are not five equilibrium distribution, concrete angle can be as shown in Figure 3, do straight line to the individual connecting hole center of circle respectively from the flange center of circle, the angle between straight line begins clockwise direction from C and is followed successively by 55 degree, 35 degree, 45 degree, 45 degree, 45 degree, 35 degree, 55 degree, 45 degree.
Linkage is positioned at iron tower orlop cross-arm place, and the above angle steel part of linkage is perpendicular to horizontal plane.
From the above mentioned, adopt this programme not only can guarantee the steadiness and the reliability of iron tower, and linkage do not depend on iron tower main material as link independently, as long as physical dimension is identical, the iron tower that main material specification is close all can be realized general.
