2) division of pre-assembled subregion: whole three-dimensional steel work is divided into five pre-assembled regions; Because treasured lid steel work is space three-dimensional structure, and installation accuracy requires very high, for ensure member install time all docking ports locus, whole precious lid steel work is divided into five pre-assembled regions, check the making precision of single member by pre-assembled this link, also can repair overproof member, make its required precision that meets on-site consolidation, installation, guarantee that the normal operation of on-site hoisting operation and on-the-spot installation quality reach specification, designing requirement simultaneously.
3) lifting segmentation and pre-assembled subregion carry out the division of factory process segmentation after determining, then by according to step 12) in each subsection of dividing carry out independent processing and fabricating by joint form, interconnective each bow member node is made simultaneously, each Pin bow member divides intersegmental connecting rod directly to mend section as the embedding of on-site consolidation, on-the-spot like this location and welding all can once-formings, do not need to adopt the method for substep welding equipment to make, simultaneously because factory's construction environment is better, can launch in enormous quantities, all welding equipment is qualified in advance to add each node, moulding bed and the location dimension etc. of on-site consolidation realized simplification to the full extent, the assembled cycle can shorten greatly.
4) main arch segmental machining, makes separately front bow member sectional members and the rear bow member sectional members in each subsection in factory, specific as follows:
41) create put together to pack moulding bed: mark on the ground center line, the appearance profile line of chord member and bracket according to the actual projection size of main arch subsection, then according to the absolute altitude of relevant position, moulding bed template is set, maintenance level after template-setup;
42) location of chord member and web member: the qualified chord member of processing is hung on respectively to assembling jig frame and position, surely line of face,mounting over the ground when location, the size of control port simultaneously, then web member between chord member is installed successively, when installation, note the sequencing between intersection otch and each web member, in adopting when welding point, the principle of symmetrical welding carries out welding, to reduce welding deformation; Because chord member is bended pipe, we adopt straight steel pipe cold presswork to be shaped, and can determine that whether qualified it is with the tolerance of sagitta and chord length, as sagitta deviation is less than 3mm, and the positive and negative 2mm of chord length;
43) welding equipment of bracket: after main arch sectional members main body welding equipment is qualified, reorientate, carry out the welding equipment of bracket; Steel pipe bracket adopts total powerstation accurately to locate when the location, behind location, on assembling jig frame, welds.
5) inferior bow member segmental machining, i.e. time centering member in factory makes each subsection separately, specific as follows:
51) create put together to pack moulding bed: mark on the ground center line, the appearance profile line of chord member and bracket according to the actual projection size of inferior bow member segmentation, then according to the absolute altitude of relevant position, moulding bed template is set, maintenance level after template-setup;
52) location of chord member and web member: the qualified chord member of processing is hung on respectively to assembling jig frame and position, surely line of face,mounting over the ground when location, the size of control port simultaneously, then web member between chord member is installed successively, when installation, note the sequencing between intersection otch and each web member, in adopting when welding point, the principle of symmetrical welding carries out welding;
53) welding equipment of bracket: after inferior bow member sectional members main body welding equipment is qualified, reorientate, carry out the welding equipment of bracket; Steel pipe bracket adopts total powerstation accurately to locate when the location, behind location, on assembling jig frame, welds.
6) scene is assembled in advance: according to five above-mentioned divided pre-assembled regions, adopt the preframed method of entity to carry out one by one respectively assembled, assembled front each assembled section is taken out respectively from correct model, then according to design feature selection reference plane, make as far as possible assembled section place steadily, moulding bed height is lower, location is convenient is principle, assembled rear regional all can intuitively reflect self assembled quality condition, two joint area places can not intuitively reflect, in order to reduce the entity preframed workload that circulates, each joint area place adopts the assembled method of computer simulation to test, concrete steps are as follows:
61) making of assembled moulding bed: carry out the line of ground line style and the setting of template according to assembled moulding bed artwork, the levelness of moulding bed template must be strict controlled in 1mm; Because treasured lid appearance and size is larger, and weight is heavier, therefore that pre-assembled moulding bed must carry out on heavy platform is pre-splicing, to prevent moulding bed generation sedimentation and deformation.Because pre-assembled moulding bed is the most important condition that ensures the pre-splicing accuracy of member, therefore assembled moulding bed must have certain bearing capacity, and must ensure the correctness that moulding bed arranges; Assembled moulding bed artwork takes out assembled segmentation according to model, then sets up coordinate and derives the coordinate at each control point, offers that workman is hinged with;
62) each member in each segmentation being hung on to assembling jig frame positions;
63) welding of each segmentation: the each segmentation of whole section and embedding are mended and installed, carries out integral solder after qualified by inspection; When welding, directly on assembling jig frame, be convenient to the weld seam of welding portion, reverse side is difficult to the region of welding and will after sectional turn-over, welds, during in welding process, strict implement divides, symmetrical, welding principle, and adopt less heat input, control the distortion of welding;
64) assembled in advance: first each large segmentation to be hung on to assembling jig frame and position, and by the making precision of pre-assembled checklist root member, repair simultaneously;
In on-the-spot pre-assembled operation, in order to ensure carrying out smoothly and installation accuracy of lifting, mark respectively each point of intersegmental involutory mark at segmentation interface, while location in high-altitude like this, both can position according to control point coordinate, also can verify according to involutory mark simultaneously; Strict implement self-inspection in assembled process, the tri-inspection system degree of examining mutually, specially examining, when measuring, checking and accepting, employing ground sample method and total powerstation carry out simultaneously, to guarantee assembled total quality;
On-the-spot preframed object is again to detect its precision of each member that factory processes whether to meet installation requirement, carried out integrality examination, but this only limits to the precision of self after single member processing, can detect the precision after each member interconnects when assembled in advance.This engineering entirety is divided into 20 large segmentations, and because each large segmentation weight is larger, on-the-spot lifting machine cannot lift, and therefore, again each large segmentation is divided into respectively to three subsections, amounts to 60 subsections;
Conventionally such a tube truss structure, it is not need to make node that single lifting divides intersegmental, directly web member and supervisor are welded, and single lifting segmentation is after produce in factory, transport cannot be carried out, and super wide or overlength, can only make at the scene, and the condition of field fabrication (comprising that machinery, equipment, place, personnel etc. can not compare with factory) but facility and required precision while installing for scene, so factory has carried out the making of component node;
This tube truss structure, due to poor rigidity, easily distortion in transportation, even the member that factory process is qualified, after being transported to scene, probably there is distortion and impact installation, therefore, on-the-spot pre-assembled situation could really reflect the truth of component quality, because node is all made, the on-the-spot end of each member can only being in place, connecting rod therebetween only need directly be laid up, then each lifting point intersegmental connecting rod is welded, just become the subsection of lifting, carrying out when install in high-altitude between segmentation and segmentation welded, thereby form large segmentation.
7) on-the-spot installation: treasured is built to steel work and be divided into 60 lifting subsections, adopt M50/75 tower crane to lift, four suspension centres of each subsection setup, suspension centre is arranged on bow member node; In the time of lifting location, between segmentation and temporary supporting, adopt the steel pipe support of Φ 180*10 to locate temporarily, between lifting segmentation and temporary supporting, adopt bearing pin node to connect; When installation, upwards carried out both sides by bottom simultaneously, complete the making of giant Buddha Bao Gai according to erection sequence below,
Field erected order is: suspension column is first installed, then large segmentation one and large segmentation 11 is installed simultaneously, large segmentation two and large segmentation 12 is installed when logical again, the rest may be inferred, and large segmentation ten and large segmentation 20 are finally installed;
Subsection 1~3 in each large segmentation and embedding benefit member carry out respectively successively, and concrete steps are as follows:
71) installation of the following suspension column of absolute altitude 6.55m: before installing, civil engineering is carried out to accurate measurement and positioning, adopt temporary supporting and cable wind rope to be fixed after installing, ensure the invariant position of embedded section before pouring concrete;
72) installation of large segmentation one, large segmentation 11: carry out setting up of temporary supporting before installation, then hang on successively the 1-3 subsection of each large segmentation and embedding therebetween and mend member;
73) installation of large segmentation two, large segmentation 12: the goodness of fit of mating interface between guarantee and lower segment section when installation, control the size of upper port simultaneously, until three subsections respectively in place qualified after, carry out embedding therebetween mend member and and lower segment section between the embedding installation of mending member;
