Description
Technical field
The present invention relates to a kind of construction techniques, are spelled in particular to a kind of large span ball type network frame dissipates in the air
Protection construction method.
Background technology
In recent years, with the fast development of computer science and technology, China's grid structure technology also enter one it is brand-new
Epoch, the modeling structure of various novelties also shows like the mushrooms after rain therewith.Grid structure with bolt-sphere joints is because of its work of constructing
Phase is short, and span is big, structure novel, reasonable stress, from heavy and light, it is handsome in appearance the advantages that, be widely used in large-scale stadium,
The places such as market, terminal, waiting room, gas station, exhibition center, cinema.
Large span space grid structure form is increasingly becoming a kind of trend for meeting people's fantasy.Spherical net rack structure
Installation mainly has 3 kinds of methods:Assembly in pieces at height, whole lockup method and aerial sliding methed.The most commonly used is Assembly in pieces at height at present
Ball type network frame is installed, but operation risk factor is higher in Assembly in pieces at height installation process, without reliable safety measure, construction operation
Personnel can only lie in safety belt in bolt sphere, the careless slightly possibility for being susceptible to high-altitude of falling, hang in installation process.
Full hall scaffold is integrally set up using ball type network frame lower part, is only capable of installing convenient for rack lower boom, winds up installation still
Safety belt can only be lain on installation bolt ball, but this scheme scaffold building amount is big, costly, the duration is also longer, causes
Unnecessary waste.
Invention content
Deficiency in for the above-mentioned prior art, the present invention provide a kind of safe and reliable, raising construction efficiency, reduction construction
The large span ball type network frame of cost dissipates in the air spells protection construction method.
The technical solution used in the present invention is：
A kind of large span ball type network frame is scattered in the air to spell protection construction method, includes the following steps：
Step 1, installation ball type network frame starting frame, according to rack integral arrangement, selecting structure stress most unfavorable combination is set up
Two between full hall scaffold, each two adjacent pillars for one across.Scaffold top completely spreads scaffold board, as operation platform
And rack temporary supporting platform；
Step 2, when rack starting frame is installed to span centre one third position, in support platform upper edge rack laterally disposed two
A jack, to prevent rack downwarp；
Step 3, in the top of rack, civil engineering structure column has been completed as fixed point, in the respectively setting one of rack both sides using both ends
The upper layer main rope of road along longitudinal direction；
Step 4, twice pair steel wire rope is laterally set along rack, secondary steel wire rope both ends pass through movable snap ring and upper layer king wire
Rope is connected, and secondary steel wire rope is slided by snap ring on the main rope of upper layer back and forth；
Step 5, when worker constructs, it is connected with secondary steel wire rope on operator's safety belt, secondary steel wire rope passes through active card
Ring can be moved forward and backward along longitudinal direction, and safety belt hitch point is guaranteed when worker's forward/backward operation；
Step 6, in the lower section of rack, using civil engineering structure column and the rack lower edge ball installed as fixed point, along net
Frame longitudinal direction is every one across one of lower layer's steel wire rope of setting；
Step 7, it is laid with activity safety net between adjacent twice lower layer steel wire rope, passes through between safety net and lower layer's steel wire rope
Movable snap ring is connected；Safety net is slided by snap ring on lower layer's steel wire rope back and forth.
Ball type network frame starting frame lower part is provided with the jack for being used to support ball type network frame.
The advantageous effect of the present invention compared with the prior art：
Large span ball type network frame of the present invention dissipates in the air spells protection construction method, is not required to be abound with full hall scaffold, saves a large amount of
Construction material；Reduce fund input；Save the duration；Construction safety risk is reduced, protection network and safety belt play double protection
Effect, ensures the life security of construction worker.

Specific implementation mode
Referring to the drawings and embodiment the present invention will be described in detail：
Attached drawing 1-3 spells protection construction method it is found that a kind of large span ball type network frame dissipates in the air, includes the following steps：
Step 1, installation ball type network frame starting frame 1, according to 2 integral arrangement of rack, selecting structure stress most unfavorable combination is taken
If two across full hall scaffold；
Step 2, it is laterally disposed in support platform upper edge rack when rack starting frame is installed to span centre one third position
Two jack 8, to prevent rack downwarp；
Step 3, in the top of rack 2, civil engineering structure column has been completed as fixed point using both ends, has respectively been arranged in 2 both sides of rack
Upper layer main rope 3 along longitudinal direction together；
Step 4, twice pair steel wire rope 4 is laterally set along rack, 4 both ends of secondary steel wire rope pass through movable snap ring 5 and upper layer master
Steel wire rope 3 is connected, and secondary steel wire rope 4 is slided by snap ring 5 on upper layer main rope 3 back and forth；
