Description

A kind of bolt-ball net frame roofing installation method
Technical field
The invention belongs to steel building technical field of construction, and in particular to a kind of bolt-ball net frame roofing installation method.
Background technology
Steel structure net rack is relatively common structure type, has big from heavy and light, rigidity, can be processed, is usually used in batch production Roof structure.In Practical Project construction, when steel construction enters construction, civil engineering concrete structure has typically been constructed completions, live Construction site condition can not change.
Rack installation method is more various, can be summarized as seven kinds of main field erected methods, respectively high-altitude dissipates Dress method, slitting or piecemeal Method for Installation, sliding method, whole hanging method, Integral Lifting, integrated lifting and folding and expanding integrally carry The method of liter.Seven kinds of methods respectively have feature, can be selected according to specific grid structure form and site condition.
But above-mentioned centralized way has respective weak point:Assembly in pieces at height needs a large amount of steel pipe scaffolds to set up Operating platform, construction period, operating expenses are higher;Slitting or piecemeal Method for Installation, whole hanging method need large lifting equipment, For narrow space, the unapproachable construction site of crane gear can not use;Sliding method needs open construction site and specially The slip device of door;Folding and expanding Integral Lifting is then the installation method used for the rack of particular design;When construction is empty Between it is narrow and small when, Integral Lifting or integrated lifting can be selected, integrated lifting uses hydraulic jacking equipment and interim branch Support, domestic common hydraulic jacking equipment stroke is 2-3 rice at present, and the jacking of rack needs repeatedly to carry out, and process is numerous and diverse, applies Safe mass control is difficult in work.
The content of the invention
Goal of the invention:The present invention is directed to deficiency of the prior art, proposes a kind of bolt-ball net frame roofing installation method, solves Determined when being lifted in medium and small span ones to steel structure net rack, due to large-scale lifting means cannot be introduced into and caused by Insurmountable steel structure net rack when can not carry out overall lifting in face of steel structure net rack on ground, and be lifted using dead man merely Lifting construction problem, while reduce work high above the ground hidden danger, accelerating construction progress.
Technical scheme:A kind of bolt-ball net frame roofing installation method of the present invention, comprises the following steps:
Step 1, assemble steel structure net rack center can lift unit;Midpoint and the center line of steel structure net rack are released, steel is installed The rod member of structure rack center line both sides, be assembled into steel structure net rack center can lift unit;
Step 2, dead man is set;The steel structure net rack center being completed can the inside of lift unit bars of eradicating are set more;
Step 3, chain block and cable wind rope are installed;Pulled each first and a chain block is respectively hung on gourd hook;Simultaneously The cable wind rope of four direction is fixed on each cable wind rope hook;
Step 4, be segmented lifting using dead man and extend out steel structure net rack can lift unit;By the chain sling on chain block with Steel structure net rack center can lift unit be connected, and by chain block by steel structure net rack center can lift unit lifted To the height that can extend out one layer, steel structure net rack center can lift unit outer ring weld one layer of rack and form steel construction net The first layer of frame can lift unit, continue to lift up steel structure net rack first layer can lift unit to the height that can extend out the second layer Degree, welded again in first layer lift unit outer ring one layer of rack formed steel structure net rack the second layer can lift unit, continue to carry Rise steel structure net rack the second layer can lift unit to the height that can extend out third layer and carry out extending out for third layer to form steel The third layer of structure rack can lift unit, and so on, until by the lifting of the lift unit at steel structure net rack center to pulling out Extended out during the maximum height that bar is supported to form the N layers of steel structure net rack can lift unit;
Step 5, the preparation continued to lift up using concrete column is operated;Second is welded on the built-in fitting of building concrete post Chain block is linked up with;The lifting bracket as rack lifting hanging point is down welded at the lower edge ball of rack simultaneously;
Step 6, the conversion of chain block;Chain block at the top of dead man is transferred into second to pull on gourd hook, simultaneously will Chain block and steel structure net rack center can the hanging point of lift unit be transformed on lifting bracket;
Step 7, be segmented lifting using concrete column and extend out steel structure net rack can lift unit;Can lift unit first to room Each hoist point of interlude of veil frame is lifted in proportion, until interlude rises to its both ends the first both ends adjacent thereto Suspend at section connecting position, then carrying out assembly with adjacent first both ends section to interlude closes up, and makes interlude and the first both ends Section integrator, forms the second interlude, then each hoist point of the second interlude is lifted in proportion, until among second Section, which is risen at the second both ends section connecting position adjacent thereto of its both ends, to be suspended, then to the second interlude and adjacent second liang End section carries out assembly and closed up, and makes the second interlude and the second both ends section integrator, the 3rd interlude is formed, by that analogy to shape Into N interludes, carry out assembly with N both ends section and close up to the complete curved surface entirety rack of formation;
Step 8, steel structure net rack is promoted to design height;Workmen utilizes the built-in fitting on concrete column and lifting branch Steel structure net rack lifting is arrived design height by frame by chain block;
Step 9, the fixation of steel structure net rack;After steel structure net rack lifting to design height, installed on steel structure net rack Net rack support, while lifting bracket and second are pulled into gourd hook excision, finally complete the fixation of steel structure net rack.
Further, the quantity of the dead man described in step 2 is 4 ~ 8, and all dead mans are symmetrical arranged.
Further, can lift unit include the described curved-surface net rack of roof of flexible steel twisted wire connection, flexible steel twisted wire with The tie point of curved-surface net rack of roof is hoist point.
Further, the both ends of interlude are placed in ground floor, and both ends section is supported close to one end of interlude by falsework, One end away from interlude is placed in ground floor.
Beneficial effect:The present invention solves when being lifted in medium and small span ones to steel structure net rack, due to big Type lifting means cannot be introduced into and caused by can not carry out overall lifting in face of steel structure net rack on ground, and use dead man merely The lifting construction problem of insurmountable steel structure net rack during lifting, while reduce work high above the ground hidden danger, accelerating construction progress.
