In this detailed description of the invention, truss comprises main couple 3 and time radiation beam 4, and main couple 3 is 8 Pin main couples, and secondary radiation beam 4 is 24 Pin radiation beams.
Steel concrete shuttering comprises standard large form, contracture template, link and radius adjusting device.Standard large form comprises standard inner formword and standard exterior sheathing, is linked into an integrated entity between standard inner formword and standard exterior sheathing by split bolt.Contracture template comprises contracture inner formword and contracture exterior sheathing, is also linked into an integrated entity by split bolt between contracture inner formword and contracture exterior sheathing; Radius adjusting device comprises encloses purlin and regulates the positive and negative leading screw of radius.
The construction method applying this platform comprises the following steps:
1) in chimney raft end face stack shell drop shadow spread, bury built-in fitting underground according to design, conventional construction chimney wall first segment reinforcing bar, template, install and to climb bar 17, bar 17 overcoat that climbs climbs bar sheath steel pipe 16, and bar sheath steel pipe 16 outer wall that climbs is processed into back taper.
The bar 17 that wherein climbs comprises climb bar and time radiation beam of main couple and to climb bar, the main couple bar that climbs is positioned at below main couple 3, and the secondary radiation beam bar that climbs is positioned at below time radiation beam 4, and main couple 3 is eight Pin main couples, every Pin main couple is provided with two main couples and climbs bar, and secondary radiation beam 4 is 24 truss structures.
Be the tapering that the long bar 17 that climbs of 1.6m processes 2.5mm at the tapering of the outer bar sheath steel pipe 16 that climbs arranged of the bar 17 that climbs.
2) set up scaffold in chimney wall center, scaffold adopts common scaffold tubes to set up.
3) the steel ring raw material transport connecting main couple 3 and time radiation beam 4 is also carried out steel ring assembling on the ground to chimney is inner.
4) central drum circle 5 is installed.
5) punching jack 18 is installed climbing on bar 17, in the released state punching jack 18 is installed and punching jack 18 is adjusted to corresponding absolute altitude.
6) install on main couple 3, secondary radiation beam 4 and main couple and revolve connecting rod 23, to promote bottom assembled good steel ring to secondary radiation beam 4 and with clamping plate, secondary radiation beam 4 to be connected with the crosspoint of swing arm under main couple by stud.
7) laying construction platform legs palm 21, at this moment the basic installation of the agent structure of whole operation platform, hydraulic power unit is installed in platform near central drum circle 5 place, debugging pumping plant also tries lifting construction platform, debug qualified rear lifting construction platform and raise 1.5m, then stack shell of constructing successively respectively saves concrete blinding, and now operation platform hoisting depth meets the installation needs of internal hanger 7, outer suspension bracket 6 completely.
8) below hitch point internal hanger 7, outer suspension bracket 6 being arranged on the Two bors d's oeuveres channel-section steel of swing arm under time radiation beam 4 and truss, by two-layer suspension bracket platform hoop crossbeam 20, internal hanger 7 and outer suspension bracket 6 are connected into a hoop entirety, suspension bracket platform hoop crossbeam 20 is laid platform legs hand cradle to form formwork platform and form removal platform, hang safety net 13 outside suspension bracket 6 outside and reveal all the details, the now installation of operation platform structure all completes.
9) chimney shaft normal construction, the bar sheath steel pipe 16 that climbs during operation platform lifting promotes together, after bar sheath steel pipe 16 lifting of climbing puts in place, the gap mortar between steel pipe lower end and concrete cavity is tamped, extract out in concrete tube wall every the 3-3.5m bar 17 that highly will climb, cavity is filled closely knit with mortar after extraction, place climbing boots in situ again, installation is climbed bar sheath steel pipe 16, climb bar 17, punching jack 18 resets, continue stack shell construction, climb bar 17 extraction displacement never allow same absolute altitude to extract the bar 17 that climbs of more than 2 groups quantity out for main couple 3 simultaneously, 8 times should be divided equally in 3-3.5m height, each extraction one, alternately extract out successively, for secondary radiation beam 4, allow the symmetrical operation of extracting two bars 17 that climb out simultaneously of same absolute altitude, but also to divide equally and extract out successively, can not the same period, the bar 17 that climbs is extracted out with the large quantity in position.
In addition, be exactly that stack shell reinforcing bar, steel concrete shuttering, concrete construction and conventional electric hoist platform reverse mould construction method are similar, just this scheme adopts two joint template overturnings, and reduce one deck than the template of routine, construction method does not repeat them here with order.
When operation platform rises to certain altitude, and finish platform loading test employing straight line elevator material loading is carried out stack shell construction, the construction method of construction method and conventional high-rise building straight line elevator is similar, also repeats no more.
