Description
Technical field
The utility model belongs to a kind of concurrent, relates in particular to the one annular FRP reinforced concrete pole with strong corrosion resistant.
Background technology
Since Germany is since 20 beginnings of the century produced first annular concrete electric pole, concurrent is at electric line, transformer station (institute), communication line, in the engineering fields such as town and country illuminating line, obtain a wide range of applications, but traditional electric pole is steel concrete material, because common concurrent is work with cracking, therefore coastal at some, the severe areas of environment such as the high and high and cold high height above sea level of soil saline and alkaline, in concurrent, the corrosion of reinforcing bar is comparatively serious, therefore steel concrete electric pole tends to occur that the concurrent causing due to the corrosion of reinforcing bar does not reach use requirement for bearing capacity, have to carry out maintenance and reinforcement, even remove, thereby greatly reduce the service life of concurrent, , easily there is Sudden failure and cause the situation of power-off in some maintenance and reinforcement electric pole not in time, brings greater inconvenience to the daily production of people, life, causes huge property loss and human casualty accident.Therefore need to produce and a kind ofly can, at the higher concurrent of ruthless area endurance quality, to adapt to the develop rapidly of State Grid's facility in each department, meet the electricity needs of each department.
FRP fibre-reinforced plastics, is the abbreviation of English (Fiber Reinforced Polymer), and FRP muscle material has that tensile strength is high, lightweight, the advantage such as corrosion-resistant.Look into newly by technology, obtain two sections of documents: 1) the Ming Qi's pure white of Wu Zhi, FRP reinforced concrete is subject to camber beam normal section force analysis, earthquake resistant engineering and strengthening reconstruction, 2006 (3): 26-30.2) just Zhang Jianwei Du Xiuli of Li Jianhui Deng ancestor, the current situation and development of FRP tendon concrete structure, About Frp/cm 2005 (4): 51-56.But these two sections of articles are all the introductions to FRP reinforced concrete material, the not research of FRP reinforced concrete pole.
Summary of the invention
The purpose of this utility model is to provide the one annular FRP reinforced concrete pole with strong corrosion resistant.
The utility model is achieved through the following technical solutions:
A kind of annular FRP reinforced concrete pole, comprise that cross section is the annular concrete body of rod, concrete body of rod inside is provided with along the FRP muscle of concrete frame body length direction spiral extension, be provided with the vertical FRP muscle circle of the frame distributing along concrete frame body length direction in FRP muscle inner side, the vertical FRP muscle circle of FRP muscle and frame is that coaxial inner conductor distributes, between FRP muscle and the vertical FRP muscle circle of frame, hoop is evenly distributed with the straight FRP muscle of longitudinal stress, and the straight FRP muscle of longitudinal stress is connected with FRP muscle and the vertical FRP muscle circle binding of frame respectively.
The utility model also comprises:
1, the concrete body of rod 1 inner side is provided with the cross FRP section bar 5 distributing along the concrete body of rod 1 length direction, and four ends of cross FRP section bar 5 are embedded in the concrete body of rod 1 inside.
2, the minimum value of the thickness of the concrete body of rod 1 is 10mm.
The beneficial effects of the utility model are:
The corrosion resistance of FRP reinforced concrete pole interior tendon material compared with common reinforced concrete pole is higher, is that ruthless area solves the measure that concurrent endurance quality is poor, problem that service life is short provides a kind of feasibility.In electric pole, have spiral helicine FRP muscle, FRP muscle circle and between the two hoop be evenly distributed with the straight FRP muscle of longitudinal stress, wherein spiral helicine FRP muscle can improve the shearing resistance of electric pole, makes electric pole more stable.At electric pole internal configurations FRP section bar, can improve significantly the stability of electric pole itself and the ability of electric pole resistance to deformation, reduce the consumption of FRP muscle material, the amount of deflection of electric pole while reducing normal use.Simultaneously in concrete admixture carbon fiber, significantly improved the adhesive property between FRP muscle and concrete.
Brief description of the drawings
Fig. 1 is the structural representation of cross section of the present utility model.
Fig. 2 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in further details.
As shown in Figure 1, FRP reinforced concrete pole, in the concrete body of rod 1, be provided with the spiral FRP muscle 2 extending along the concrete body of rod 1 length direction, be provided with the vertical FRP muscle circle 3 of the multiple tracks frame distributing along the concrete body of rod 1 length direction in spiral FRP muscle 2 inner sides, the vertical FRP muscle circle 3 of spiral FRP muscle 2 and frame is coaxial inner conductor and distributes; Between spiral FRP muscle 2 and the vertical FRP muscle circle 3 of frame, hoop is uniformly distributed many straight FRP muscle 4 of longitudinal stress.Inlay cross FRP section bar 5 in the concrete body of rod 1 inside, the elongated configuration of FRP section bar 5, four ends of section bar need be embedded in the concrete body of rod 1 inside, and four ends of its medium section are fixed on electric pole FRP muscle cage with FRP bonding adhesive.The carbon fiber of admixture concrete quality 0.8% in electric pole concrete used, and together stir with concrete aggregate.It is the FRP muscle material with ribbing of surface sand-blasting processing that electric pole muscle material used all needs, and wherein between spiral bar and vertical muscle, the vertical circle of frame and vertical muscle, forms FRP muscle cage with galvanized wire colligation.The thickness of concrete cover of the straight FRP muscle 4 of longitudinal stress can be less than concrete cover to reinforcement thickness in reinforced concrete pole, and its thickness minimum can be 10mm.Adopt the technique of pull wheel type centrifugal forming to produce, and carry out maintenance in early stage in the steam-cured mode of normal pressure, after this can carry out common maintenance, but should note keeping electric pole to have enough humidity around.Fig. 2 is structural representation of the present utility model.
Coastal at some, soil saline and alkaline is high and the severe area of environment such as high and cold high height above sea level, because the corrosion resistance of the FRP muscle in FRP reinforced concrete pole is stronger, corrosive substance is invaded in concrete very little to the Effect on Mechanical Properties of muscle material in electric pole, therefore concurrent can not reduce its supporting capacity because of the corrosion of interior tendon material, improves the concurrent object in application life thereby reach.In addition the tensile strength of FRP muscle is obviously greater than plain bars, and therefore the main muscle as prestressed concrete electric pole by FRP muscle, can make full use of its high-intensity characteristic, reaches the object that reduces presstressed reinforcing steel material use quantity.At electric pole internal configurations FRP section bar, can improve significantly the stability of electric pole itself, simultaneously because the modulus of elasticity of FRP muscle is little, the ability of the resistance to deformation of the concurrent of simple configuration FRP muscle a little less than, when use, amount of deflection is relatively large, can improve significantly the ability of electric pole resistance to deformation and configure this kind of FRP section bar, reduce the consumption of FRP muscle material, the amount of deflection of electric pole while reducing normal use.
