Description
Technical field
The present invention relates to a kind of bracing or strutting arrangement of transmission line of electricity, specifically relate to a kind of double angle column foot formula switching node.
Background technology
In recent years, along with the quick growth of national economy, power industry development rapidly, has promoted the fast development of iron tower of power transmission line industry.For the body cost of shaft tower can be reduced more, solve the problem of steel pipe production capacity deficiency simultaneously, a kind of main material adopts steel pipe, the mixed type steel tower of angle steel arises at the historic moment.
Double angle steel tower is the one of iron tower of power transmission line, double angle steel tower comprises the tower head, tower body and the tower leg that connect in turn from top to bottom, in building course, needs to arrange column foot plate, column foot plate is connected with the tower leg of double angle steel tower, is fixed the tower leg of double angle steel tower by column foot plate.Because the weight of double angle steel tower supports mainly through the connection of tower leg (steel pipe), column foot plate and double angle, therefore in double angle steel tower, steel pipe, double angle switching node connect extremely important.Meanwhile, the pattern that steel pipe-double angle switching node connects has three kinds, and namely column foot formula connects, and---joint is located at internode, joint is located at internode to column foot formula connection---joint is located at Nodes, Flange joint---.Wherein, Flange joint is in power transmission tower node (crosspoint of main oblique material) top, is blocked by the main material of power transmission tower, recycling Flange joint; And column foot formula connects the main material that need not block above node, simultaneously Flange joint expends the higher and reliability that connects of steel, manpower lower than column foot formula.In column foot formula connects, joint is located at the connected mode of Nodes, rod member is arranged more difficult.
Therefore, need to provide a kind of improvement opportunity scheme for above-mentioned prior art deficiency.
Summary of the invention
The object of the invention is to overcome the aspect problems such as above-mentioned prior art expends steel and manpower is serious, connecting rod is complicated, construction is difficult, a kind of double angle column foot formula switching node is proposed, namely joint is located at the column foot formula connection of internode, its connected mode is simple, constructability, and Path of Force Transfer is comparatively clear, reduce steel pipe consumption, greatly improves economic benefit and social benefit.
For achieving the above object, the present invention is by the following technical solutions:

Further, described horizontal main steel plate is connected to the top of described vertical main steel plate, and described boots plate is cross is welded on described horizontal main steel plate.
Further, described stiffening rib is welded between described horizontal main steel plate and vertical main steel plate, and described stiffening rib is fixed on the end of described boots plate.
Further, between the main material of described steel pipe, horizontal main steel plate and vertical main steel plate for being welded to connect.
Further, the axis of the main material of described steel pipe and the axes intersect of the oblique material of each angle steel are in a bit.
Further, the main material of described angle steel with between boots plate for being connected for bolt; The oblique material of described angle steel with between vertical levels plate for bolt is connected.
Further, the angle of the oblique material of described angle steel and the main material of described steel pipe is between 45 ° ~ 315 °; The angle of the oblique material of described angle steel and the main material of described steel pipe is 45 °, 90 °, 135 °, 225 °, 270 °, 315 °.
Further, described angle steel is double angle.
Compared with immediate prior art, technical scheme provided by the invention has following excellent effect:
(1) reduce steel pipe consumption, alleviate the not enough problem of steel pipe production capacity.
In prototype steel tower tower body, most of rod member of middle-column main material and oblique material, the oblique material of the main material of cross-arm and front is steel pipe, and angle steel proportion is very little; After adopting novel steel tube-double angle tower, part below lower cross-arm adopts steel tube component, and adopt angle steel with upper part (comprising tower body), angle steel proportion increases greatly.
(2) easy construction.
Upper main material becomes angle steel by steel pipe, and its connected mode no longer adopts welding, but bolt connects, therefore reduces difficulty of construction to a great extent.
(3) column foot formula node adopts double angle material, improves ultimate bearing capacity of joints, enhances the stability of structure.
(4) adopt joint to be located at the column foot formula node of internode, Path of Force Transfer is comparatively clear, and connected mode is simpler, saves steel materials.
