Abstract
The present invention relates to the ground wire of electric power pylon, be specially a kind of recessed dress steel tower ground wire of L-shaped band steel near-earth.Solve existing steel tower ground wire to be easily tampered and manufacturing process relative complex, relatively costly problem.This L-shaped band steel near-earth recessed dress steel tower ground wire includes straight band steel, one end of band steel forms, by being perpendicular to twice vertical bending in wide direction of band steel, the L-shaped part making band steel attach column foot, column foot concrete base gabarit, and the end of L-shaped part vertically has upper bolt hole and lower bolt hole；The mid portion of band steel forms ground wire body；The other end of band steel forms anchor head to the side vertical folding of ground wire body.Earth resistance of the present invention is little；Manufacturing process is simple；Cost is low；Anti-theft is good, and band steel is not easily sawed-off, adds low putting and is loaded in concrete base groove, saws, further increase theft difficulty under thief's inconvenience.
Description
Technical field
The present invention relates to the ground wire of electric power pylon, be specially a kind of recessed dress steel tower ground wire of L-shaped band steel near-earth.
Background technology
The ground wire of existing electric power pylon, by connection column plate, lead-in wire, buried plate constitute.Lead-in wire diameter 16mm round steel, one is welded with connection column plate, and other end is welded with ground buried plate.Connection column plate, buried plate be used that the band steel manufacture of wide 40mm, thick 4mm, long 160mm.Connection column plate there are two bolts hole, are loaded on tower leg from 500mm place, ground with M16 bolt；Lead-in wire applies puts tower leg, column foot, concrete base with entering, the buried underground 1000mm of ground buried plate.
Owing to connection column plate connects with dismountable bolt, very quick detachable；Applying owing to going between and put, and be round steel, available hands hacksaw is sawed-off；Easily it is tampered.Steel tower loses the derivative hidden danger of ground connection.Existing steel tower ground wire needs the operations such as welding, manufacturing process relative complex when manufacturing.Cost is of a relatively high.
Summary of the invention
This invention address that existing steel tower ground wire is easily tampered and manufacturing process relative complex, relatively costly problem, it is provided that a kind of recessed dress steel tower ground wire of L-shaped band steel near-earth.
The present invention adopts the following technical scheme that realization: the recessed dress steel tower ground wire of L-shaped band steel near-earth, including straight band steel, one end of band steel forms, by being perpendicular to twice vertical bending in wide direction of band steel, the L-shaped part making band steel attach column foot, column foot concrete base gabarit, and the end of L-shaped part vertically has upper bolt hole and lower bolt hole；The mid portion of band steel forms ground wire body；The other end of band steel to the side vertical folding of ground wire body formed anchor head (so-called folding be ground wire body with folding after the anchor head that formed get together or fit；So-called vertical folding refers to that the axis of anchor head is vertical with the axis of ground wire body).During use, L-shaped part is loaded on a facade of column foot, and lower bolt hole is from plane 100mm place on column foot base plate, and the setting of L-shaped part enables band steel to attach column foot, concrete base gabarit, is placed in the groove that concrete base is reserved, then enters ground, and namely anchor head is embedded in underground.
The invention has the beneficial effects as follows: 1. contact area increases to 1.76 times than existing ground wire, earth resistance is little, and earthing effect is good.2. manufacturing process is simple, adopts ready-made band steel, blocks, punches, the technique such as clod wash, it is not necessary to welding or other complex processes.3. cost is low, relatively manufactures round steel ground wire, saves the high welding sequence of working hour expense and the long materials of material-saving 400mm.4. anti-theft is good, and band steel is not easily sawed-off, adds low putting and is loaded in concrete base groove, saws, further increase theft difficulty under thief's inconvenience.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention；
In figure: 1-ground wire body, 2-upper bolt hole, bolt hole under 3-, 4-anchor head.
Detailed description of the invention
The recessed dress steel tower ground wire of L-shaped band steel near-earth, including straight band steel, one end of band steel forms, by being perpendicular to twice vertical bending in wide direction of band steel, the L-shaped part making band steel attach column foot, column foot concrete base gabarit, and the end of L-shaped part vertically has upper bolt hole 2 and lower bolt hole 3；The mid portion of band steel forms ground wire body 1；The other end of band steel to the side vertical folding of ground wire body 1 formed anchor head 4(what is called fold be ground wire body with folding after the anchor head that formed get together；So-called vertical folding refers to that the axis of anchor head is vertical with the axis of ground wire body).When being embodied as, band steel adopts " 40 × 4-A3 " or " 50 × 4-A3 " galvanizing.Anchor head 4 length inherits existing round steel ground wire ground buried plate length.The concrete size of L-shaped part is determined according to column foot, the true form of column foot concrete base gabarit and size.
