Description
Technical field
The present invention relates to technical field of buildings, and in particular to a kind of steel-making tower steel structure platform is staggered installation of welding side
Method.
Background technique
The skyscraper of full steel structure compares more at home at present, and main pooled applications are in conference and exhibition center, grand theater, sport
In terms of shop and individual Business Buildings.And the high-rise steel structure of metallurgical system construction is concentrated mainly on converter and blast furnace region, highly exists
60m or 80m or so.The characteristics of converter system steel structure platform is that the more height differences of layer are big, and centralized arrangement has heavy equipment, converter system
The comprehensive progress of Steel Structure Installation directly affects the installation effectiveness of steelmaking system.
In general, technique steel construction in converter region takes incremental mode to be installed by chapter, lift, install,
Installation, welding of landing beam etc., but for multi-storey steel structure installation, welding sequence is affected to structure both shrinks how
Ensuring to make steel tower steel structure platform orderly, precisely to install is the emphasis controlled.
Summary of the invention
The purpose of this invention is welded aiming in steel-making high building multi-storey steel structure conventional mounting welding process due to concentrating
It scoops out power and leads to the offset of steel columns of steel structures verticality, welding contraction distortion, solve control platform erecting and welding method, to improve
The efficiency of Steel Structure Installation, quality stability and the problem of reduce operation safety risk.
To solve the above problems, the present invention the following technical schemes are provided:
A kind of steel-making tower steel structure platform is staggered installation of welding method, is using halfpace in interlayer stage+module
The welding deformation generated due to welding concentrated stress is resisted in supporting role in the process, and construction procedure is as follows:
Step 1: preparation of construction
A, surveying setting-out carries out repetition measurement to steel-column foundation using theodolite and level, and measuring goes out steel-column foundation in length and breadth
To center line；
B, component site acceptance checks the component marched into the arena, and the size of component carries out repetition measurement and is identified；
Step 2: lower platform and component installation
A, lower prop I, lower prop II, lower prop III are successively lifted, measures lower prop I, lower prop II, lower prop using theodolite and level
III verticality and absolute altitude；
B, once grouting is carried out to lower prop I, lower prop II, lower prop III after centering, grouting height control is away from steel column base
Plinth upper surface about 200mm；
C, one layer of platform of construction:
Construction transverse frame beam and longitudinal framing beam: the first installation transverse frame beam between lower prop I and lower prop II utilizes
Vierendeel girder is lifted the bracket upper surface to steel column I and steel column II by lifting equipment, and Vierendeel girder and steel column I and steel column II is made to keep water
It is flat, connecting plate I is installed and high-strength bolt that two sides take, high-strength bolt need to be by just twisting and twisting eventually；
Longitudinal framing beam is identical with the installation mode of transverse frame beam as the connection type of steel column；In this way, longitudinal frame
Set a roof beam in place, transverse frame beam lower prop I, lower prop II, lower prop III are connected it is integral, connection type be high-strength bolt connection, wouldn't weld
It connects；
The longitudinal platform secondary beam of construction and horizontal platform secondary beam: it after girder I and girder II are installed, is lifted using lifting equipment
Secondary beam successively installs connecting plate II, installation bolt, then welded seam；Other longitudinal platform secondary beams, horizontal platform in the platform
Secondary beam mounting means is identical；
D, it constructs two-layer platform, the component mounting means same layer platform in two-layer platform；
E, two-layer platform starts to weld the component in one layer of platform after the installation is completed；First soldering frame is set a roof beam in place and steel column I, steel column
The beam upper end weld seam of II connection, then welded grider lower end weld seam；
Step 3: upper brace and component installation
A, while Member Welding in one layer of platform, start that upper prop I, upper prop II, upper prop III are installed, and respectively under
Column I, lower prop II, III butt welding of lower prop；
B, the component in three layers of platform, mounting means same layer platform and two-layer platform are installed；
C, the component in three layers of platform after the installation is completed, then carries out Vierendeel girder in two-layer platform and steel column I, steel column II connect
The welding of the beam upper end weld seam, beam lower end weld seam that connect, the welding manner of welding manner same layer platform；
D, the component installation in four layers of platform is carried out, mounting means is identical with above one layer of platform, then carries out three layers of platform
Interior Vierendeel girder connecting welding work；
E, the Vierendeel girder connecting welding work in four layers of platform is finally carried out；
F, back-grouting work is carried out to the suspension column of lower prop I, lower prop II, lower prop III.
Further, in above-mentioned steps three the installation centering of upper prop I, upper prop II, upper prop III with the lower prop in step 2, but
The centering point of verticality is with upper prop I, upper prop II, III top center of upper prop and lower prop I, lower prop II, III suspension column center pair of lower prop
It should be worth.
Compared with prior art, the invention has the benefit that
1) verticality of steel column is influenced this method avoids welding deformation is caused due to the concentration welding because of Vierendeel girder, then
The difficulty for causing upper platform to install guarantees the orderly progress of erecting and welding, improves construction efficiency and installation accuracy；
2) present invention improves product quality and working efficiency, significantly reduces security risk, reduces large-scale crane
Using working hour, engineering cost is reduced；With practicability and operability.
