Description
Technical field
The utility model relates to a kind of concrete-filled double skin steel tube bar of transmission line of electricity, belong to the overhead power transmission line pole tower technical field.
Background technology
Along with the high speed development of urban construction, land resources is more and more rare, for the higher 220kV of electric pressure, 500kV with the many back transmission lines of tower, conventional shaft tower since floor space large, in the urban district by running into very large difficulty.Steel pipe pole can well solve the city and take up an area problem, because its floor space is little, can directly be built up in the greenbelt of urban road, the policy that causes when avoiding on like this can be largely because of circuit through the building of population comparatively dense is processed dispute, saves simultaneously the land resources in city.
The multiplex list in the low voltage grade of conventional steel pipe pole returns or double back transmission line, and the shaft material adopts the thin-walled hollow steel pipe.Along with day by day rare with land resources of improving constantly of urban power consumption demand, the same tower of voltage levels three times, four back transmission lines will embody more superiority.Along with the increase of external load, hollow steel pipe can't satisfy load bearing requirements, as improving simply caliber, will bring that steel pipe partial is stable, a series of difficulties such as processing and manufacturing and construction and installation.For guaranteeing the safe and reliable and economy of power transmission rod design, shaft master material selects the concrete-filled double skin steel tube composite component better to address the above problem.
Hollow sandwich steel tube concrete pole is because the interaction between steel pipe and concrete, compares with steel tube component to have the following advantages:
1) compressive strength is high, and structural entity rigidity is large;
2) crashworthiness is good, and shock resistance is good;
3) structural damping ratio is larger, has good wind resistance, can resist the attack of violent typhoon;
4) local stability is good, but the saving steel consumption;
Compare with solid concrete filled steel tubular member, have following advantage:
1) carry out in the cross section, bending rigidity is large;
2) boring can be saved concrete amount;
3) from heavy and light, can save the Foundation Design cost.
In the above-mentioned advantage, the lighter characteristics of conducting oneself with dignity especially are fit to it and use in the high-tension line of city.Zone, Plain, south soft layer is deep, presses down the often governing factor of basic engineering of load, and lighter deadweight can be saved Foundation Design amount and investment greatly.Therefore these characteristics of concrete structure with hollow sandwich have determined that it has very superior mechanics and economic advantages as transmission line structure.
Summary of the invention
The purpose of this utility model is to overcome deficiency of the prior art, and the transmission line of electricity concrete-filled double skin steel tube bar of the strong and economy of supporting capacity is provided.
The utility model is achieved by the following technical solution: it comprises: hollow sandwich steel tube concrete pole, hollow steel pipe member, inside and outside wall flange, common flange, wire cross-arm, described hollow sandwich steel tube concrete pole is made of outer steel pipe, interior steel pipe and middle sandwich concrete, described hollow sandwich steel tube concrete pole divides and intersegmentally connects by the inside and outside wall flange, is connected by common flange between described hollow sandwich steel tube concrete pole and the hollow steel pipe member.
Described hollow sandwich steel tube concrete pole is fixedly mounted in the reinforced concrete foundation; Described inside and outside wall flange is made of jointly inside and outside orchid and outward flange, at described hollow steel pipe member described wire cross-arm is installed.
Power transmission rod described in the utility model mainly bears Compact-bending Load compound action (take Moment as main), the bottom section moment of flexure is large and cross section, top moment of flexure is less, therefore the bottom adopts hollow sandwich steel tube concrete pole to satisfy the load bearing requirements of intensity, monolithic stability and steel tube component local stability, the top shaft can adopt the hollow steel pipe member along with moment of flexure reduces.Hollow sandwich steel tube concrete pole divides intersegmental employing inside and outside wall flange to connect, to satisfy the common stressed requirement of global sections; Wire cross-arm and shaft are with bolts; The concrete-filled double skin steel tube bar adopts stone bolt to be connected with sole plate.
As a kind of improvement, the member section of concrete-filled double skin steel tube is made of jointly outer steel pipe, interior steel pipe and sandwich concrete, and the local stability of higher cross section resistance to compression, anti-bending bearing capacity and steel pipe walls both is provided, and has effectively controlled again the deadweight of member.For guaranteeing the jointly stressed of inside and outside double-layer pipe, special design the inside and outside wall flange carry out the connection of hollow sandwich steel tube concrete pole, the inside and outside wall flange is made of jointly inner flange and outward flange.
Compared with prior art, the beneficial effects of the utility model are: compare with conventional power transmission tower, reduced floor space, site select is also more flexible; Compare with the common steel tube bar, improved greatly resistance to compression, bending resistance and the local stability bearing capacity of member, enlarged the range of application of power transmission rod and saved rolled steel dosage; Compare with the concrete filled steel tube bar, alleviated dead load, reduced basic role power, saved the base concrete consumption.
