Abstract
The utility model discloses a transverse crack reinforcing device for a reinforced concrete electric pole with a circular section, which comprises two pairs of pole clamps which are connected through bolts. Each pair of pole clamps consists of two arc clamps matched with each other, the two arc clamps are connected with each other by the aid of bolts, and a cylindrical cavity is formed between the two arc clamps. During use, when a transverse crack is formed on the reinforced concrete electric pole, the two pairs of pole clamps are respectively mounted on the upper portion and the lower portion of a pole body with the transverse crack, the bolts for connecting the arc clamps are screwed on firstly, radial stress is applied to the crack of the pole body so as to fix the arc clamps, and then bolt distance between the two pairs of pole clamps respectively arranged on the upper portion and the lower portion of the pole body can be adjusted, the bolts can be screwed to apply axial force to the crack on the pole body, so that expansion of the crack can be prevented and the structural rigidity and strength of the pole body are enhanced. Compared with the prior art, the transverse crack reinforcing device has the advantages that the maximum stress value is reduced while expansion of the crack is avoided after reinforcing operation is completed by the aid of the transverse crack reinforcing device; and the transverse crack reinforcing device is simple in operation, free of power interruption and low in cost.
Description
Technical field
The utility model relates to a kind of ring section reinforced concrete pole transverse cracks bracing means that is used for.
Background technology
At present, in China's most of areas, most of 110kv (and following) ultra-high-tension power transmission line adopts the part anchor support except that special location, special leap, all adopts steel reinforced concrete pole.The reinforced concrete pole of ultra-high-tension power transmission line mainly is made up of steel concrete mobile jib, steel concrete fork beam or steel fork beam, backguy and cross-arm etc., and the steel concrete mobile jib has isometrical and two kinds of tapers (dialling the tip), and general bar section by 6m or 9m is welded.
China's transmission line of electricity uses reinforced concrete pole, and the history in existing 50～60 years has all accumulated rich experience at aspects such as design, manufacturing, installation, operation maintenance.But,, reflect also in the practice that this form of structure of reinforced concrete pole exists some need study and the problem that further solves really along with the growth of pole tower operation time and operation, the operation of new bar.
Under same condition, steel reinforced concrete pole is more damaged than other concrete steel buildings, aging speed is fast, and application life is short.Electric pole top is general damaged slight.But it is the most serious near ground, the general breakage of electric pole part more than the face of land.Concrete frame ftractures and crackle generally occurs in down, the stage casing, and crack width is 0.1～10mm, and length does not wait to bar section total length from 0.3m; Perhaps: the bar section produces circumferential crack around part hoop or the edge, and these phenomenons generally also occur in down the stage casing; Or: generally aging, carbonization, the loose variable color of burn into material appear in the bar section, and intensity descends, and often closely the breakage of face portion burn into is comparatively serious, and the electric pole bottom occurs that large and small different bulk is peeled off, hollowing and main reinforcement, the serious corrosion of stirrup etc.In above-mentioned these damaged forms, with the bar section produce lobe and longitudinal crack problem comparatively generally, the most outstanding, have in addition new line cracking and crack problem all appear, quickened wearing out of shaft tower, obviously shortened service life.
The principal element of steel concrete development that shaft tower cracks is: wind shakes, wind pendulum, frost heave, temperature alternating and corrosion of steel bar.Under, the effect year after year multiple once, constantly develop into long and wide crack in these factors time.Aging, the carbonization of steel concrete shaft tower, corrosion breakage under similarity condition than aging, the damaged fast main cause of other reinforced concretes; Except that extraneous environment is abominable really; Also have bar section concrete protective layer thickness less than normal, main muscle and stirrup are often near external surface.Add that carbonization, corrosion of steel bar, three kinds of destructions of cracking interact, form vicious circle, cause shaft tower than damaged fast, the life-span weak point of other steel concrete.The damaged reason of steel concrete shaft tower and damaged form are very complicated, carbonization, aging, frost heave circulation, the corrosion of reinforcing bar and derivation property cracking is normally, inevitably, need just can take place behind certain time limit.Yet the structural failure crack of shaft tower is along with the increasing of rod member, the increase of slenderness ratio, " bamboo is split effect " just produce after progressively manifesting.This breakage generally occurs in newly-built or running time of the long circuit, makes other damaged forms obtain quickening and arriving in advance, with the application life that shortens shaft tower greatly.Therefore, the prevention and the processing of ultra-high-tension power transmission line steel concrete shaft tower lobe are vital for long-term safety, the economical operation of circuit.
Reinforcement measure to steel concrete shaft tower crackle is damaged is generally oozed crackle enforcement filling through adopting high-strength clay and height to ooze waterproof agent, to eliminate the cutting damage in crack as far as possible.It is bigger, consuming time longer that this method is implemented engineering quantity, owing to irritate that to ooze back cement tissue odds even, causes stress to concentrate simultaneously, and to preventing the cracks can spread poor effect, tower structure intensity is difficult to guarantee.
Summary of the invention
To above-mentioned prior art, the utility model provides a kind of ring section reinforced concrete pole transverse cracks bracing means that is used for.
The utility model is realized through following technical scheme:
A kind of ring section reinforced concrete pole transverse cracks bracing means that is used for comprises the binary link folder, connects through bolt between the binary link folder; Every secondary bar cramp is to be made up of two arc clips that cooperatively interact, and connects through bolt between two arc clips, forms a cylindrical cavity between two arc clips.
Preferably, connect through four bolts between the said binary link folder, one group in twos on four bolts are divided into two groups, are distributed in arc clip both sides.
Preferably, connect through four bolts between said two arc clips, one group in twos on four bolts are divided into two groups, are distributed in arc clip both sides.
Use: when transverse cracks appears in the ring section reinforced concrete pole, the bar cramp of one copy utility model respectively is installed, is tightened the bolt that connects the arc clip earlier at body of the tower cracks upper-lower position; The shaft cracks is applied radial stresses with fixing arc clip; Regulate the bolt distance between the binary link folder up and down again, tighten, the shaft cracks is applied axial force; Prevent cracks can spread, increase the shaft rigidity of structure and intensity simultaneously.
In the practical application,, the operation conditions behind the strutting of pole is carried out complete detection through to shaft multiple spot vibration survey and foundation vibrations and mechanics strain measurement.Detect the back result and show that Scheme of Strengthening has obtained extraordinary effect.
Compared with prior art, the beneficial effect of the utility model is: after reinforcement was accomplished, maximum stress value reduced, and crackle is no longer expanded simultaneously, and simple to operation, need not have a power failure, and cost is low.
