The specific embodiment
Thinking with the division of net shell piecemeal:
(1) form of piecemeal---in conjunction with supporting point position, axis,
On net shell profile, have no rule, but study carefully its form of structure, the person in charge that is to the employing of main shaft steel pipe is respectively radiated in its southern side, and the inferior of pipe fitting employing between main shaft managed, and each axis angle reduces from east to west gradually, and the axis of projection line length then progressively increases; Hoop is responsible for by several isohypse and is cut apart; Net shell bottom all is shelved on the structure bottom ring beam.If being divided into some according to axis in length and breadth merely, this lifts, in the cumulative errors of eliminating the net shell, solve aspects such as mutual net shell lifting and the influence of electric welding welding stress and all bigger difficulty will be arranged.Comprehensive each big factor has worked up " water droplet shape " radial monolayer steel pipe net shell piecemeal technology, promptly the net shell is divided into the apical ring beam---be used for the location benchmark of integral net shell; The lattice piecemeal is jumped along each radiation axis in apical ring beam bottom---and the projection of radiation axis is the radiation straightway, after pressing the axis piecemeal, the horizontal level of each interblock can position by the spindle tube on every both sides, jump lattice and can avoid the formation of cumulative errors so that check separately according to total axon net every net shell subregion; Adopt loose mail to fill a vacancy between the piece, can further carry out the position of net interblock, can alleviate or eliminate simultaneously factors such as the temperature difference, weather and structure be installed the influence that causes.
Behind the piecemeal, one, can make the net shell overwhelming majority in the floor manufacture assembly unit, can be by making the overall precision of accuracy guarantee net shell, and can reduce amount of high-altitude operation; Two, electric welding amount in net shell high-altitude only limits to butt joint between the piece and the connection between the loose mail, utilizes reasonable, symmetrical welding process the welding deformation influence can be controlled at lower degree.
(2) carry out the branch block analysis in conjunction with computer model
Behind the net shell piecemeal, the distortion in the net shell hoisting process will become a critical process in the construction control again, also be " water droplet shape " key of radial monolayer steel pipe net shell piecemeal process implementing.In order to understand the lifting deflection of each piece net shell, by utilizing infrastructure software, each piecemeal is adjusted and optimized the Work condition analogue analysis, finally determine the segmented areas that satisfies the lifting deformation accuracy.
(3) form of joint
After the net shell divides block end, each minute interblock and piece and loose mail between be connected, the contraposition between the joint becomes again needs the problem that solves in the construction.One, because the connection between each pipe fitting of net shell is tubular joint, if the tubular joint between high-altitude welding steel pipe, difficult quality guarantee; Two, piecemeal net shell banjo fixing butt jointing is more, and how accurately contraposition also will influence the quality and the progress of installing.Therefore, " water droplet shape " radial monolayer steel pipe net shell piecemeal technology center tap cut-point is arranged in length and breadth about net shell joint head top 20cm, and adopts the joint form of inner sleeve.So divide, if mainly consider if the lower contact contraposition has deviation on the net shell, about the about 2m of the single steel pipe jib-length of upper wire shell, relative Φ 219 steel pipes, slenderness ratio is relatively large, docks adjustment more among a small circle; The inner sleeve node can be simplified the butt joint of steel pipe, plays the effect of positioning control simultaneously.3, the enforcement of net shell piecemeal lifting

Passenger traffic complex building southern side net shell span is bigger, and net shell rigidity is less, in order to control the distortion in the piecemeal net shell installation process, considers to set up support in elongated isohypse position, net shell middle part, adjusts for the temporary fixed and location of piecemeal net shell.
The steel screen installation procedure is:
Apical ring beam installation → northern half subnetting shell piecemeal is installed → the southern half part net shell piecemeal installation → loose mail installation → net shell reservation place's of closing up installation
