According to the lattice angle iron power transmission tower body, the strength and the rigidity of an iron tower are improved through increasing the number of the iron tower main materials, so that the aim of improving the carrying capacity of the iron tower is achieved; and under the condition of the same occupation area, the number of the tower body main materials is increased, so that the space between the tower body main materials is reduced, the length of the tower body diagonal member is reduced, the stability of the tower body diagonal member is favored, and the economical efficiency and the reliability of the power transmission iron tower are improved.
Description
Technical field
The utility model relates to a kind of electric power pylon tower body, is particularly useful for the lattice angle steel structure tower body of UHV transmission line.
Background technology
At present, the worldwide electric power pylon overwhelming majority all is to adopt hot rolling equal leg angle member, and through the space truss structure that bolt is formed by connecting, two limbs of its four main materials (chord member) link to each other with oblique material (web member) through bolt.Main material is the main bearing member of iron tower, and the load of iron tower mainly leans on tower body master material to bear, so the specification of main material and rigidity and the supporting capacity that number has determined iron tower in the electric power pylon.
In recent years along with the construction of UHV transmission line; The height of electric power pylon is increasingly high, and load is also increasing, even select the angle steel of maximum specification in the actual engineering; Also be difficult to satisfy the whole rigidity of iron tower and the requirement of intensity; Therefore tower body master material has adopted by bolt and batten plate single angle has been fixed the structure that forms the Two bors d's oeuveres angle steel, yet the Two bors d's oeuveres angle steel can make iron tower whole reliability variation, and makes the increase rate of tower body master material supporting capacity limited.In addition, along with the increase of iron tower height, traditional angle steel Tata leg root is opened and the spacing of main material becomes big, and the size lengthening of corresponding oblique material guarantees that the stability of oblique material becomes very difficult.Traditional above-mentioned shortcoming of lattice angle steel electric power pylon becomes its major obstacle of in UHV transmission line is built, using of restriction.
The utility model content
The purpose of the utility model is the drawback to prior art, a kind of good reliability is provided, can satisfies the lattice angle steel electric power pylon tower body of UHV transmission line requirement.
The said problem of the utility model realizes with following technical proposals:
A kind of lattice angle steel electric power pylon tower body comprises tower body master material, the oblique material of tower body and gusset plate in the formation, wherein, the number of tower body master material is more than four, and said tower body master material and the oblique material of tower body fuse through bolt at the gusset plate place.
Above-mentioned lattice angle steel electric power pylon tower body, the number of said tower body master material is six, tower body master material centre of form line is the regular hexagon shape on the tower body cross section.
Above-mentioned lattice angle steel electric power pylon tower body, said tower body master material is a standard-sized sheet angle angle steel, the angle of release α of angle steel two limbs=120 o, tower body master material is connected through gusset plate list limb with the oblique material of tower body.
The beneficial effect of the utility model is: one, the number through increasing tower body master material but not specification improves the strength and stiffness of iron tower; Need not to adopt Two bors d's oeuveres angle steel or customized especially big specification angle steel; The purpose that improves the iron tower bearing capacity be can reach, thereby the economy and the reliability of electric power pylon improved.Two, under the identical floor space situation, the increase of tower body master material number can reduce tower body master material spacing, thereby reduces the oblique material length of tower body, helps improving the stability of the oblique material of tower body, increases the bearing capacity of electric power pylon.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described further.
Fig. 1 is the partial structurtes sketch map of the utility model;
Fig. 2 is that the tower body master material of the utility model is arranged sketch map.
Each label is among the figure: 1, tower body master material, 2, the oblique material of tower body, 3, gusset plate, 4, bolt.
The specific embodiment
Referring to Fig. 1, Fig. 2, the utility model comprises tower body master material 1, the oblique material 2 of tower body and gusset plate 3 in constituting, and it is characterized in that: the number of tower body master material 1 is more than four, and said tower body master material 1 couples together through bolt 4 at gusset plate 3 places with the oblique material 2 of tower body.
Referring to Fig. 2, the number of the utility model tower body master material 1 is six, and tower body master material centre of form line is the regular hexagon shape on the tower body cross section.
Referring to Fig. 1, Fig. 2, the utility model tower body master material 1 is a standard-sized sheet angle angle steel, the angle of release α of angle steel two limbs=120 o, and tower body master material 1 is connected through gusset plate 3 single limbs with the oblique material 2 of tower body.
Referring to Fig. 1, Fig. 2, the utility model is different from the lattice angle steel tower of four traditional tower legs, and as the most preferred embodiment of the utility model, iron tower tower leg number is six, arranges the oblique material 2 of single tower body between the tower body master material 1, to increase the stability of tower body master material.Fig. 2 shows the regular hexagon structure that the tower body master material 1 cross section centre of form connects into, and tower body master material 1 adopts standard-sized sheet angle angle steel, and its angle is 120 degree, and two limbs of tower body master material 1 lay respectively in two planes of body of the tower.In the present embodiment; Through increasing the number of transmission of electricity tower body master material 1, increased the integral rigidity and the supporting capacity of iron tower, and under identical floor space situation; Tower body master material 1 spacing is little; Oblique material 2 length of tower body are short, the good stability of the oblique material 2 of tower body, thus can satisfy the UHV transmission line requirements on Construction.
