May further comprise the steps during enforcement:
1) set up the load-bearing scaffold, net shell and ring fine strain of millet carry out the diffusing assembly of high-altitude original position, and cast steel supporter and herringbone column are installed after the roof system moulding.
2) net shell core adopts the whole lifting of computer-controlled hydraulic system, and periphery and ring fine strain of millet are along the assembly unit on the mold of ground of hoop burst, with large-tonnage crawler crane hoisted in position.Cast steel supporter and herringbone column shift to an earlier date installation in position before the lifting.
3) it is in place that net shell employing fortune is enclosed the method that extends out, progressively promotes, and ring fine strain of millet is at installation on ground, and integral body promotes in place, and after cast steel supporter and the herringbone column's installation, the net shell is realized docking in the air with ring fine strain of millet.
4) it is in place that net shell employing fortune is enclosed the method that extends out, progressively promotes, and behind installation cast steel supporter and the herringbone column, encircles fine strain of millet and lift with the large-tonnage mobile crane behind the spelling of ground along the hoop segmentation.
5) it is in place that net shell employing fortune is enclosed the method that extends out, progressively promotes, and integral body promotes after the assembly unit aloft of ring fine strain of millet, and behind installation cast steel supporter and the herringbone column, the net shell aloft closes up with ring fine strain of millet.
Cast steel supporter is installed: cast steel supporter, form (as figure three: the cast steel supporter structure chart), be installed on the radially outward-dipping 15 ° built-in fitting by cast steel components and the rotatable system of ball pivot.Erection procedure is as follows:
1. on built-in fitting, emit control point, cast steel supporter center and control axis with total powerstation, emit the control sideline and weld location-plate according to the control axis.
2. each parts of cast steel supporter are formed wholely on ground, used the mobile crane hoisted in position, locate with built-in fitting spot welding after accurately adjusting the cast steel position base by location-plate.
8. with propping up pad with flitch behind the position of jack by the method adjustment foundry goods 1 of messenger wire.
Herringbone column's installation: the herringbone column is passed through mutually by two steel pipes and is formed by connecting.Lower end and cast steel supporter are welded to connect after pegging graft, and welding is passed through mutually with ring fine strain of millet in the upper end.Need realize aerial location during installation under heeling condition, erection procedure is as follows:
1. group is checked intersecting mouth to the herringbone column with cover die on ground typing mold, and weld seam is passed through in welding mutually.
2. accurately measure allocation control points and carry out control mark.
8. lift the herringbone column with mobile crane, bottom and cast steel supporter socket connection, it is temporary fixed that top adds jack with wire rope.
4. lock interim drag-line, welding herringbone column and cast steel supporter butt weld after proofreading and correct ground subpoint and herringbone column's control mark with transit.
The installation of ring fine strain of millet: ring fine strain of millet system, adopt the diffusing assembly of high-altitude original position, the fortune circle fortune section method of controlling, erection procedure is as follows:
1. each is enclosed annular steel pipe and be decomposed into plurality of units (according to requirement of engineering) by processing and on-the-spot spelling, node area is avoided in the docking port position.
2. utilize mounted herringbone column to be the strong point, with the H shaped steel that is provided with between per two groups of herringbone columns is the interim strong point, with the lifting of two automobile handling sections than the thick steel pipe steel pipe, with the installation accuracy of every section of level gauge, the control of total powerstation fortune section, until than thick steel pipe steel pipe closure.At this moment, the herringbone column with formed the stable structure system than the thick steel pipe steel pipe.
3. the steel pipe that ring is thin relatively in the assembly welding on the mold of ground and vertically web member, the lifting of fortune section, with be connected than the thick steel pipe steel pipe, with total powerstation cooperate the messenger wire method accurately the vertical web member of control with fix than the concentricity of thick steel pipe steel pipe and with cable wind rope, the perpendicular web member of welding with than the thick steel pipe intersecting mouth.
4. web member 6,7 is installed, and by the thin relatively steel pipe of ring in the fortune section location and installation of web member 6,7,, check with total powerstation.
5. spelling web member 12,13 on the mold of ground is formed integral hoisting behind the quadrangular pyramid, by the relative fine steel tube of web member 12,13 fortune section location and installation outer shrouds until closure.
The installation of net shell: welding net shell part, for just putting the quadrangular pyramid welded spherical node, main member is welding hollowing ball and seamless steel pipe (ERW).The method that adopts the fortune circle to extend out, progressively promote in the construction.Hoisting System adopts the unipods dead man system by the traction of strand mill.At first, on 5.0 meters concrete platforms of height, emit control point, center and control axis, build to establish and support the brick pier, begin assembly unit net shell by the center, the fortune circle begins to promote in the time can't outwards continuing assembly unit on every side to external diffusion, each hoisting depth satisfies to the requirement that extends out 2～3 circles, successively circulation.Promoting the dead man system is made up of interior ring, middle ring, outer shroud three circle dead mans.Along with the assembly unit that extends out of net shell, three circle dead mans are finished the lifting task of net shell in the mode of relay.In ring, middle ring dead man is deactivated after middle ring, outer shroud dead man are stressed fully respectively and remove.
The net shell closes up in the air with ring fine strain of millet: net shell part is independently constructed as two distinct area separately with ring fine strain of millet system, after finishing, ring fine strain of millet system construction self formed the stable structure system, after the net shell promotes and puts in place, under the suspended state of high-altitude, realize closing up, finish whole roof structure and install with aerial butt joint of ring fine strain of millet system.Is initial closing up a little with two orthogonal axis with four intersection points that encircle fine strain of millet, begin the net shell and encircle closing up of fine strain of millet by the splicing method that looses, and the order propelling, welding job is followed up in proper order, finishes finally closing up of net shell.
