Step 5, Synchronous lifting;
Step 6, installs string and props up the embedding benefit rod member between dome and the interior ring of outer ring roof system truss, discharges lifter active force, and the support force that makes string prop up dome is all transferred to outside roof system support system;
Step 7, the dismountings such as lifting means, measure for improvement, support jig.
Described individual layer string props up dome ground monomer stretch-draw lifting construction method, and step 1 also comprises: described hoisting frame ensures the safe distance on vertical and horizontal space in lifting construction, for promoting the reserved necessary usage space of steel strand of use; In addition, note also rigidity and the stability of hoisting frame.
Described individual layer string props up dome ground monomer stretch-draw lifting construction method, and step 2 also comprises: the necessary reserved passageway setting such as strut, prestressed cable in described platform for lining; Quality control in assembled process, prevents that structure from, because of the malformation that assembled, construction factor, welding etc. bring, affecting construction quality.Key is to control three-dimensional space position, the integral assembling size Control of net shell node, and the relative position while ensureing installation on ground is correct.
Described individual layer string props up dome ground monomer stretch-draw lifting construction method, and in step 3, in described lifting, anchorage, on a vertical line, in be controlled at ± 20mm of the error of perpendicularity, and ensures that steel strand cabling is smooth and easy
After outer ring of the present invention trussed construction shell mould roof construction completes, the construction of central area suspended-dome structure, adopt position under the design attitude of dome structure to set up consolidation service platform, the key jobs such as the assembled welding of net shell and the laying stretch-draw of prestressed cable have all been constructed on job platform.Meanwhile, arrange the anchorage of lifting construction on the surrounding grid node of dome structure, on the completed trussed roof directly over lifting anchorage, design and installation promotes anchor point and lays lifting means and steel strand.Suspended-dome structure ground monomer stretch-draw being completed by Synchronous lifting technology promotes in place.Both the project construction difficult problem having solved, again economic, the safe and reliable construction task that completed.Fact proved, this construction method is the best construction method that the suspended-dome structure of this type operating mode is installed, not only economical, saves the duration and safe and reliable.The present invention, by the improvement of construction method, has solved the insurmountable construction difficult problem of conventional construction method, and work progress is safe and reliable, and whole efficiency significantly promotes; Realize automation control and simulation analysis in conjunction with operation, improved construction safety and reliability; Save tall and big bearing frame measure and Large-scale Hoisting equipment investment, saved material, reduced installation cost.
Detailed description of the invention
Below in conjunction with detailed description of the invention, the present invention is further illustrated:
The present invention is taking center stadium engineering in Huludao City's physical culture as example: its suspended-dome structure form as: suspended-dome structure is connected on the ring truss of outer ring roof system, string prop up dome self by single layer welding ball-receiving net shell, prestressed cable and the strut that links between the two be connected otic placode etc., suspended-dome structure prestressed cable is made up of three ring ropes and corresponding radial cable, structure construction difficulty is very big, is mainly assembled, the laying stretch-draw of drag-line and the problem of suspended-dome structure installation in position that solves net shell.According to this design feature, on the surrounding grid node of dome structure, arrange the anchorage of lifting construction, on the completed trussed roof directly over lifting anchorage, design and installation promotes anchor point and lays Synchronous lifting lifting means and steel strand.Suspended-dome structure ground monomer stretch-draw being completed by Synchronous lifting technology promotes in place.Specific construction step is as follows:
