Abstract
The invention relates to a quickly combined large lattice type crossing frame. The quickly combined large lattice type crossing frame comprises a plurality of holding column bodies, six-way connecting components and stay wires, wherein each two adjacent holding column bodies are connected through one six-way connecting component; the stay wires are fixed to the holding column bodies to keep the crossing frame stable. Compared with the prior art, the quickly combined large lattice type crossing frame has the advantages of stable structure, high strength, capability of performing standard assembly, high working efficiency and the like.
Description
Technical field
The present invention relates to a kind of high voltage overhead lines construction crossing frame, especially relate to a kind of large-scale lattice crossing frame of Rapid Combination.
Background technology
The general employing of high voltage overhead lines crossing construction set up the methods such as Moso bamboo crossing frame, steel pipe crossing frame, live crossing frame as crossing over support body, and the method for catch net is sealed on top again, and this respect China construction environment complexity and construction level are all higher than abroad.Said method is for general height, the situation that construction environment and time etc. meet specified conditions is no problem, but for highly higher, the leap of engineering time compactness is just very difficult, even if often increase larger leap cost input, 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 construct at night, increased construction risk.
Summary of the invention
Object of the present invention be exactly in order to overcome the defect that above-mentioned prior art exists, provide a kind of Stability Analysis of Structures, intensity 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 kind of large-scale lattice crossing frame of Rapid Combination, comprise that thick pillar body, six leads to fitting and bracing wire, described thick pillar body is provided with a plurality of, leads to fitting connect between adjacent thick pillar body by six, described bracing wire is fixed on thick pillar body, keeps crossing frame stable.
Described six to lead to fitting be that the cube structure of screw is all set on six faces, and the face that described thick pillar body leads to fitting by bolt and six is connected.
Described six to lead to the area of each face of fitting identical with the area of thick pillar body cross-section.
Described a plurality of thick pillar bodies lead to fitting by six and connect into chair form or rectangular build crossing frame.
Described crossing frame is provided with and between a plurality of, adjacent crossing frames, is connected with bearing rope and protection network.
Compared with prior art, the present invention has following beneficial effect:
1, configuration aspects: because sky way railway height is generally higher or very high, periphery construction environment is most complicated, and building and mattess are more, and underground not open conduit wiring is more, other construction method needs that bracing wire is more should not be used.In this structure, first adopt framework self-stabilization structure, reduced the dependence to bracing wire, secondly according to spanning height, utilize respectively the different cross section poles such as a large amount of 450,600,700,900mm to be 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 to bear multiple fission conductor broken string load, secondly rational frame structure, has reduced wind and carried and conduct oneself with dignity.
3, construction method aspect: reduced as dependence that live crossing frame method coordinates bracing wire and construction, reduced as the construction discreteness risk of mao bamboon frame and steel pipe frame etc., the present invention has accomplished construction standardization assembling, mechanization assembling, rapid-assembling etc., reduces the security implication that causes surrounding enviroment and may be caused by leap thing because of factors such as construction interruption, inherently safes.
4, construction cost aspect: first the present invention can unlimitedly reuse, the Work tool cost of having made thinner, secondly reduce reduce environment as occupation of land, bracing wire, may cause the use cost of underground utilities damage etc., improved in addition the service efficiency of mechanization, reduced cost of labor.
5, speed of application aspect: improved the service efficiency of mechanization during construction, accomplished to complete for 1～2 day the construction of place's crossing frame, be far superior to the construction period that the above large-scale mao bamboon of a 20m of place or steel pipe crossing frame need 2 weeks left and right time.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the end view that the present invention six leads to fitting.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.The present embodiment be take technical solution of the present invention and is implemented as prerequisite, provided detailed execution mode and concrete operating process, but protection scope of the present invention is not limited to following embodiment.
As shown in Figure 1, a kind of large-scale lattice crossing frame of Rapid Combination, comprise that thick pillar body 1, six leads to fitting 2 and bracing wire, described thick pillar body 1 is provided with a plurality of, 1 of adjacent thick pillar body leads to fitting 2 by six and connects, described bracing wire is fixed on thick pillar body 1, for auxiliary the stable of the rear crossing frame of assembling that keep.A plurality of thick pillar bodies lead to fitting by six and connect into chair form or rectangular build crossing frame, and shape can arbitrarily change.Fig. 1 is chair form crossing frame.
As shown in Figure 2, six to lead to fitting 2 be that the cube structure of screw 3 is all set on six faces, and the face that described thick pillar body leads to fitting by bolt and six is connected, and generally uses 3～5 faces during assembling.
There is sizes in the cross section of pole body, and six to lead to the area of each face of fitting identical with the area of thick pillar body cross-section, comprises 450*450,600*600,700*700, the plurality of specifications such as 900*900.
Described crossing frame is provided with between a plurality of, adjacent crossing frames and is connected with bearing rope and protection network, in order to protection, is crossed over thing.
As adopt 600*600 pole body to set up, and single crossing frame height is 25.8m, and length is 12m, and 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.
Claims (5)
