Description
Technical field
The present invention relates to the present invention relates to power circuit capital construction technical fields, and in particular to lattice column crossing frame
And erection method.
Background technique
In power construction line construction, it is related to living across constructing and often takes the technological measure set up across rack,
Such as Moso bamboo crossing frame, steel pipe crossing frame etc..All there is the deficiency of some aspects in these traditional crossing frames, cannot be well adapted for
Under the new situation live across construction requirement.If Moso bamboo crossing frame land occupation is big, require high to landform is set up, it is long to set up the period, fits
It is low with voltage class；Steel pipe crossing frame is from great, transport and installation inconvenience etc..
In order to solve problem above, there is lattice column crossing frame, have stability high, transport, set up conveniently, peace
Full blast is nearly low, solid and reliable feature, and whole to use high strength steel structure composition, traditional lattice column crossing frame is by singly leading
Column realizes that structure is there are unstable, and bearing capacity is limited, and higher to the flatness requirement for setting up ground, the early period used
Engineering trouble, it is necessary to the stronger lattice column crossing frames of the more firm bearing capacity of invention thus to meet existing line work
The requirement of journey crossing construction.
Summary of the invention
The technical problems to be solved by the present invention are: single principal post lattice crossing frame structural instability, bearing capacity is poor,
It is high to the flatness requirement of ground, cross-arm length trouble is adjusted according to voltage class.
The present invention provides the lattice column crossing frames to solve the above problems.
The present invention is achieved through the following technical solutions:
Lattice column crossing frame, including two columns being oppositely arranged, the column includes being in conplane armful
Bar, cross-arm and goat's horn bar, the symmetrical connecting stay wire in the two sides of the pole are simultaneously fixed by bracing wire and ground, one end of the cross-arm
It is connect at the top of the pole, the goat's horn bar is connected to the cross-arm upper surface, uses soft company between the top of two poles
Fitting is removably flexible coupling.

Preferably, the length of the flexible joining part is greater than the horizontal distance between the pole, so that two poles
In the case where topography out-of-flatness, not tight flexible joining part, which can play, adjusts the problem of misplacing between two poles, reduction pair
The requirement of topography flatness.
Currently preferred lattice column crossing frame, the flexible joining part are connect by shackle with the pole, shackle
Dismount it is very convenient, voltage class difference in the case where, can according to block width select different length flexible joining part from
And adapt to the requirement of different voltages grade.
Currently preferred lattice column crossing frame, the Hard link part are angle steel.
The erection method of lattice column crossing frame, includes the following steps:
Step 1: stud location；
Step 2: column assembling；
Step 3: flexible joining part is installed between the top of two poles；
Step 4: installation bracing wire.
Currently preferred lattice column crossing frame erection method further includes in installation flexible joining part in the step 3
Later, Hard link part is installed at the middle part of two poles.
Currently preferred lattice column crossing frame erection method installs the specific step of flexible joining part in the step 3
Suddenly are as follows: four-way flange is installed on two tops of pole, and four metal shackles are installed in the four-way flange mounting hole, and shackle is curved
Head is unified inside, then the software connector of suitable length is mounted on to unload and is buckled, and the flexible joining part is not tight, in this way can be with
Guarantee that flexible joining part plays the bring dislocation due to topography injustice of two poles of adjustment, reduces structure installation to topography flatness
Strict demand.
Currently preferred lattice column crossing frame erection method, the specific steps of the installation Hard link part are as follows:
Mounting hole is arranged in the middle part of the pole, and Hard link part is detachably connected in mounting hole, pacifies after installing flexible joining part
Hard link part is filled, guarantees further to consolidate overall mechanism in the case where pole position is formed.
Currently preferred lattice column crossing frame erection method installs the specific steps of bracing wire in the step 4
Are as follows: two sides are symmetrical arranged 2 bracing wires at the top of every pole, and angle is not greater than 45 ° over the ground for the bracing wire, and bracing wire projects angle
It is 90 °, is symmetrical arranged 2 groups of 4 bracing wires in every pole on both sides of the middle.Symmetrically arranged bracing wire can be further ensured that the perpendicular of pole
Directly, the stability of total is ensured.
The present invention have it is following the utility model has the advantages that
1. the present invention, as supporter, improves the bearing capacity and stability of entire crossing frame by two poles of setting.
2. the top of two poles of the invention is using being flexible coupling, it is adjustable because two poles caused by topography is uneven it
