Abstract
The present invention relates to a kind of large-scale lattice crossing frame of Rapid Combination, comprise that pole body, six leads to fitting and bracing wire, described pole body is provided with multiple, leads to fitting connect between adjacent pole body by six, described bracing wire is fixed on pole body, keeps crossing frame stable. Compared with prior art, the present invention have Stability Analysis of Structures, intensity high, can carry out standardization assembling, the advantage such as increase work efficiency.
Description
Technical field
The present invention relates to a kind of high voltage overhead lines construction crossing frame, especially relate to the large-scale of a kind of Rapid CombinationLattice crossing frame.
Background technology
The general sides such as setting up Moso bamboo crossing frame, steel pipe crossing frame, live crossing frame that adopts of high voltage overhead lines crossing constructionMethod is as crossing over support body, and the method for catch net is sealed on top again, this respect China construction environment complexity and construction waterOn average higher than abroad. Said method is for general height, and the situation that construction environment and time etc. meets specified conditions does not haveHave problem, but for highly higher, the leap of engineering time compactness is just very difficult, even if often increase largerCross over cost input and can not solve leap security problems, not only need the deeper cooperation by the unit of leap,Often need to be crossed over during thing is stopped transport and be constructed at night, increased construction risk.
Summary of the invention
Object of the present invention is exactly to provide a kind of Stability Analysis of Structures, strong in order to overcome the defect that above-mentioned prior art existsSpend high, can carry out standardization assembling, the large-scale lattice crossing frame of the Rapid Combination of increasing work efficiency.
Object of the present invention can be achieved through the following technical solutions:
A large-scale lattice crossing frame for Rapid Combination, comprises that pole body, six leads to fitting and bracing wire, described inPole body be provided with multiple, between adjacent pole body by six lead to fitting connect, described bracing wire be fixed on embraceOn bar body, keep crossing frame stable.
Described six to lead to fitting be the cube structure that screw is all set on six faces, and described pole body passes throughThe face that bolt and six leads to fitting is connected.
Described six to lead to the area of each of fitting identical with the area of pole body cross-section.
Described multiple pole bodies lead to fitting by six and connect into chair form or rectangular build crossing frame.
Described crossing frame is provided with and between multiple, adjacent crossing frames, is connected with bearing rope and protection network.
Compared with prior art, the present invention has following beneficial effect:
1, structure aspects: because sky way railway height is generally higher or very high, periphery construction environment is most multipleAssorted, building and mattess are more, and underground not open conduit wiring is more, and other construction method needs bracing wire moreShould use. In this structure, first adopt framework self-stabilization structure, reduced the dependence to bracing wire, secondly according to leapHighly, utilize respectively a large amount of 450,600,700, the different cross section pole such as 900mm is assembled into crossing frame structure,Cross section is larger, and load is larger, can scaffolding height higher.
2, intensity aspect: first utilize pole to be far superior to the high strength of mao bamboon and building steel tube, conscientiously accomplish energyEnough bear multiple fission conductor broken string load, secondly rational frame structure, has reduced wind and has carried and conduct oneself with dignity.
3, construction method aspect: reduced as live crossing frame method to bracing wire and construction coordinate on dependence, subtractFew as the construction discreteness risk of mao bamboon frame and steel pipe frame etc., the present invention has accomplished construction standardization assembling, mechanizationAssembling, rapid-assembling etc., reduce and cause surrounding enviroment and can by leap thing because of factors such as construction interruptions, inherently safesThe security implication that can cause.
4, construction cost aspect: first the present invention can unlimitedly reuse, the Work tool cost of having made thinner, secondlyReduce reduce environment as occupation of land, bracing wire, may cause the use cost of underground utilities damage etc., improved in addition machineThe service efficiency of tool, has reduced cost of labor.
5, speed of application aspect: improved the service efficiency of mechanization when construction, accomplished to complete in 1～2 dayThe construction of place's crossing frame, be far superior to the above large-scale mao bamboon of a 20m of place or steel pipe crossing frame needs about 2 weeksThe construction period of time.
Brief description of the drawings
Fig. 1 is structural representation of the present invention;
Fig. 2 is the side view that the present invention six leads to fitting.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail. The present embodiment is with the technology of the present invention sideCase is that prerequisite is implemented, and has provided detailed embodiment and concrete operating process, but protection model of the present inventionEnclose and be not limited to following embodiment.
As shown in Figure 1, a kind of large-scale lattice crossing frame of Rapid Combination, comprises that pole body 1, six leads to connectPart 2 and bracing wire, described pole body 1 is provided with multiple, and 1 of adjacent pole body leads to fitting 2 by sixConnect, described bracing wire is fixed on pole body 1, for auxiliary the stable of the rear crossing frame of assembling that keep. MultiplePole body leads to fitting by six and connects into chair form or rectangular build crossing frame, and shape can arbitrarily change. Fig. 1For chair form crossing frame.
As shown in Figure 2, six to lead to fitting 2 be the cube structure that screw 3 is all set on six faces, and described embracesThe face that bar body leads to fitting by bolt and six is connected, and generally uses 3～5 faces when assembling.
There is sizes in the cross section of pole body, and six lead to the area of each of fitting and the face of pole body cross-sectionLong-pending identical, comprise 450*450,600*600,700*700, the plurality of specifications such as 900*900.
Described crossing frame is provided with between multiple, adjacent crossing frames and is connected with bearing rope and protection network, in order to protectionCrossed over thing.
As adopt 600*600 pole body to set up, and single crossing frame height is 25.8m, length is 12m,Width is 8m. Single crossing frame needs 64 sections of 600*600 pole bodies (4m is long), and six lead to 16 of fittings.As adopt 900 pole bodies highly for 26.7m.
