Description
Technical field
The invention belongs to science of bridge building or other structural steelwork fields, in particular to a kind of steel tower column design and construction side
Method.
Background technology
Steel tower column is widely used in science of bridge building, and because steel tower column height is high, construction weight is big, and generally use " is divided at present
Segment factory manufacture, segmented assembly at the scene connect height " design and construction method.When segmented scene connects high, generally there is two
Kind connection method, a kind of method that method is welded to connect between segment, another method are connected between segment using high-strength bolt
Method.
For being welded to connect, because the girth welding cycle is grown, and steel construction segment lifting assembled speed is relatively fast, to steel
King-post installation period, which is formed, to be restricted, and if certain steel tower column segment under normal circumstances is after installation is complete, generally requires to wait 4-5 days or very
To the longer time, the segment and next segment (note are treated：Next segment refers in following segment) after the completion of seam welds, Fang Nengjin
The upper segment of row (note：A upper segment refers in segment above) installation, head tower weld during tower crane be in idle state, by welding
Control critical circuits are connect, so as to restrict installation speed.
For high-strength bolt connection, installation progress is very fast for it is welded to connect relatively, the duration is restricted small.But because complete
Section is all connected using high-strength bolt, and high-strength bolt connecting structure input amount is huge, increases cost, and increase later maintenance is difficult
Degree, and harmful effect is caused to steel tower column appearance.And if wait tunneling boring high-strength bolt is all applied after twisting, then install one
Segment, will also restrict the duration to a certain extent.
The content of the invention
It is an object of the invention to：It is proposed a kind of head tower column construction method of bolting and welding, both made with extremely low engineering
Valency and maintenance difficulties, and there is high construction efficiency.
The object of the invention is realized by following technical proposals：
A kind of steel tower column design and construction method of bolting and welding, it is characterised in that comprise the following steps successively, wherein n is just
Integer：
Step 1：The (n+1)th segment is lifted, and is connected by part high-strength bolt connecting structure with the n-th segment, high-strength bolt
The dosage of connecting structure need to only meet the dead weight for undertaking two to three segment head tower segments thereon；
Step 2：The n-th+2 segment is lifted, and is connected by part high-strength bolt connecting structure with the (n+1)th segment, high-strength spiral shell
The dosage of bolt connecting structure need to only meet the dead weight for undertaking two to three segment head tower segments thereon；Meanwhile carry out the n-th segment with
Except high-strength bolt connecting structure is with the girth welding of exterior domain between (n+1)th segment；
This stage, the gravity load of the (n+1)th segment and the n-th+2 segment are undertaken by high-strength bolt connecting structure, welded
The n-th segment and the (n+1)th intersegmental weld seam do not undertake upper load；
Step 3：Continue the n-th+3 segment of lifting, and be connected by part high-strength bolt connecting structure with the n-th+2 segment, it is high
The dosage of strength bolt connecting structure need to only meet the dead weight for undertaking two to three segment head tower segments thereon；Meanwhile carry out (n+1)th
Except high-strength bolt connecting structure is with the girth welding of exterior domain between segment and the n-th+2 segment, this in stage the n-th segment with the (n+1)th section
The intersegmental weld seam in addition to high-strength bolt connecting structure finishes welding, alternatively, removing high-strength spiral shell between the n-th segment and the (n+1)th segment
Weld seam beyond bolt connecting structure can be completed before the n-th+3 segment lifting；
This stage, the (n+1)th segment, the n-th+2 segment, the gravity load of the n-th+3 segment are undertaken by high-strength bolt connecting structure,
The n-th segment welded does not undertake top lotus with the (n+1)th intersegmental weld seam, the (n+1)th segment and the n-th+2 intersegmental weld seam
Carry；
Step 4：Continue the n-th+4 segment of lifting, and be connected by part high-strength bolt connecting structure with the n-th+3 segment, it is high
The dosage of strength bolt connecting structure need to only meet the dead weight for undertaking two to three segment head tower segments thereon；Meanwhile carry out n-th+2
Except high-strength bolt connecting structure is with the girth welding of exterior domain between segment and the n-th+3 segment, this, the (n+1)th segment was with n-th+2 in stage
Weld seam between segment in addition to high-strength bolt connecting structure finishes welding, alternatively, except height between the (n+1)th segment and the n-th+2 segment
Weld seam beyond strength bolt connecting structure can be completed before the n-th+4 segment lifting；
In this stage, the n-th segment and the intersegmental high-strength bolt connecting structure of n+1 are removed, seam crossing above segment weight
Amount, which is transferred to, has welded the weld seam of completion and has undertaken；After high-strength bolt connecting structure is removed, the area joints welding is carried out, until should
All welding finishes seam at the merogenesis of segment；
Step 5：According to abovementioned steps, similarly promote, carry out the connection construction of other head tower segments.
Alternatively, when high-strength bolt connecting structure releases between certain segment, solder joint length reaches entirely between the segment
Section length is 80% or even more than 90%.
In the method for the present invention, between steel tower column segment and segment, a small amount of high-strength bolt connecting structure connection is first passed through, to undertake
The dead weight of two to three segment head tower segments thereon, without whole high-strength bolt connecting structure of constructing, in this way, certain segment is pacified
After the completion of dress, without waiting for the segment and the indirect seam welding in next segment, you can carry out segment installation.Installed in certain segment
After the completion of, first pass through high-strength bolt connecting structure and be connected with next segment, thereafter, while a segment on continuing lifting, tightly
Then the Partial seams welding in addition to high-strength bolt connecting structure between the segment and next segment is carried out, until its welding finishes.
After seam welds beyond high-strength bolt connecting structure, high-strength bolt connecting structure is removed, and the area joints are welded,
So complete the welding of tunneling boring weld seam.In the case of general progress, when certain segment tunneling boring weld seam welding finishes, it newly pacifies above
Fill segment and save left and right in 2-3, therefore, when actual design is constructed, consider that high-strength bolt connecting structure undertakes the head tower dead weight of 2-3 segments
.Moreover, when high-strength bolt connecting structure releases, solder joint length reaches tunneling boring length 80% or even 90%
More than, and seam crossing stress level is very low at this time, there is no at high-strength bolt connecting structure with other first welding regions because
Weld it is asynchronous and caused by stress state difference condition, do not influence structural stress state.
The foregoing main solution of the present invention and further alternatives thereof can be freely combined to form multiple schemes, be this
The scheme that invention can be used and is claimed；And the present invention, between (each non conflicting selection) selection and between other selections
It can also be freely combined.Those skilled in the art can understand have after the present invention program is understood according to the prior art and common knowledge
Multiple combinations, are the claimed technical solution of the present invention, do not do exhaustion herein.
Beneficial effects of the present invention：Not only there is extremely low project cost and maintenance difficulties, but also there is high construction efficiency.
