Along with universal with many times technology of tower of the construction of China's extra-high voltage grid and transmission line of electricity, steel tower is more obvious to the trend of large load and large scale development, makes the superiority of steel tube tower application more and more cause people's concern.Compare with angle steel tower, steel tube tower member windage effect is little, rigidity of section is large, iron tower construction member is few, power transmission is clear, reliable in structure, be conducive to strengthen the ability of the opposing of structure under extreme condition natural calamity, and can saving steel and base concrete, good Social benefit and economic benefit there is.
Electricity east, Anhui send (Huainan-Shanghai) project of transmitting and converting electricity (to be called for short: extra-high voltage East Route Project) be China article one 1000kV common-tower double-return circuit, adopt steel tube tower structural shape completely, as shown in Figure 2.According to the research work in early stage, substantially determine that the ripe production capacity of domestic steel tube tower only has 160,000 tons/year, there is larger breach contradiction with the amount of ten thousand tons of engineering all fronts 25-30.State Grid Corporation of China is from many-sided expansion in-depth such as scientific research, design, production research, especially strengthen standardized designs and the measure such as optimization and processing technology of steel tube tower, under the prerequisite of ensure quality, farthest improve production work efficiency, obtained great successes and significant benefit, but the production pressure of East Route Project steel tube tower is still very large.Consider the application of steel tube tower in other electric pressure transmission lines of electricity, the production capacity deficiency of steel tube tower has become seriously keeping in check that it promotes on a large scale again.
Summary of the invention
Novel steel tube---the angle steel mixing tower that provides a kind of transmission line of electricity to use is provided the purpose of this utility model, in the situation that keeping steel tube tower structure superiority, suitably improves the ratio of angle steel material in steel tower, to alleviate the problem of steel tube tower production capacity deficiency in engineering.
And an angle steel mixing UHV transmission steel tower, this electric power pylon turriform is double loop tangent tower, comprises the tower head, tower body 6 and the tower leg 7 that connect successively; It is characterized in that:
Tower head by earth wire support 1, upper cross-arm 2, in cross-arm 3, lower cross-arm 4 and tower body center pillar 5 form, described upper cross-arm 2, middle cross-arm 3, lower cross-arm 4 are arranged from top to bottom, all perpendicular to tower body center pillar 5, arrange, and take tower body center pillar 5 as axis symmetry, described earth wire support 1 is arranged on the both side ends of cross-arm 2;
Tower head is connected by steel pipe angle steel transition node 8 with tower body 6;
Described tower head part all adopts angle iron component to make;
Tower body 6 adopts steel tube component to make with tower leg 7.
Further, described transition node 8 is arranged in the lower cross-arm main material of 4 lower plane and the internode more than main material intersection point of tower body center pillar 5, adopts column foot template formula, base plate, boots plate and stiffener, consists of.
The utlity model has following technique effect:
Under steel tower, the above tower head of cross-arm position (comprising earth wire support 1, upper cross-arm 2, middle cross-arm 3, lower cross-arm 4 and tower body center pillar 5) all adopts angle iron component, and joint structure is simple, easy to connect; Tower body 6 and tower leg 7 all adopt steel tube component, simple for structure, power transmission is clear, can give full play to the load-carrying properties of material, effectively reduces steel tower weight.Compare with conventional steel tube tower, novel mixing tower, in the situation that keeping steel tube tower structure superiority, significantly improves the ratio of angle steel material, can effectively alleviate the problem of steel pipe production capacity wretched insufficiency in current China work transmission line.
