Description
Technical field
The present invention relates to a kind of isolation operation platform, be specifically related to a kind of superstructure working with substructure isolation
Isolation operation platform.The invention still further relates to the construction method of above-mentioned isolation operation platform.
Background technology
Square coal bunker engineering is domestic first honeycomb type coal bunker, employing reinforced concrete structure, and long 210.35m is wide
60.45m, high 45m, warehouse is made up of 48 hexagon coal bunkers, and 48 honeycomb storehouses are respectively by three groups of (often 16 honeycomb storehouses of group) groups
Becoming, each honeycomb storehouse is warehouse stalk structure at more than 20.6m, and below 20.6m is steel scuttle.First joint steel coal hopper has lifted
Bi Hou, for making the construction of stalk section Tong Bu carry out with steel coal hopper assembly under storehouse, needs arrange isolation operation platform at 20.6m.
At present, continuous brackets or employing large-scale steel structure is typically used isolation platform to be set and enters for tall and big silo structure
Row construction.Set up and there is many problems during Full space support construction: one being that number of holders is big, set up inconvenience, stability is relatively
Difference, adds the input of human and material resources, financial resources simultaneously；Two is that scaffolding height is higher, and safety coefficient reduces, and sets up speed slow, executes
The work cycle is long；Three is that substructure cannot be constructed simultaneously, affects integral construction progress, it is impossible to meet construction period.And use big
Shaped steel structure arranges isolation platform and there is also some drawbacks: one is to increase material puts into, and large-scale steel isolation is taken to tear open and is both needed to high ton
Position crane coordinates, and adds the input of human and material resources, financial resources；Two is to take to tear speed open slowly, and safe pressure is big, long construction period.
Summary of the invention
For drawbacks described above present in prior art, the invention provides a kind of new isolation operation platform, can be effective
Solve in full framing and large-scale steel isolation construction safety coefficient is low, personnel, goods and materials put into big, superstructure and lower junction
The problem that structure cannot be constructed simultaneously, progress can not be guaranteed and cost is high.
The present invention is achieved by the following technical solution: a kind of ultra-large type boundling polygon coal bunker group's Multifunctional partition from
Operation platform, is characterized in that: include that the Vierendeel girder along polygon coal bunker is spaced the some I-steel being evenly arranged, described I-shaped
Steel passes described Vierendeel girder, and its one end is positioned at the inner side of described Vierendeel girder, and its other end is positioned at the outside of described Vierendeel girder, described
I-steel is fixing to be embedded in described Vierendeel girder, between described I-steel thereon surface use reinforcing bar be welded as one whole
Body, the termination being positioned at every I-steel inside described Vierendeel girder is provided with at least two circular hole, the I-shaped inside described Vierendeel girder
By to drawing reinforcing bar and positive silk is to drawing and forming bar-mat reinforcement at the zone line of Vierendeel girder between steel, every to drawing the two of reinforcing bar
Holding one end of positive silk described in connecting respectively, the other end of described positive silk is with the circular hole of corresponding I-steel termination even
Connecing, described bar-mat reinforcement top completely spreads steel plate and fixes.
In the present invention, the region inside Vierendeel girder, by arrange down between I-steel positive silk with to drawing reinforcing bar to drawing
Laying and reticulate, form bar-mat reinforcement, upper berth steel plate forms isolation.I-steel is also can serve as superstructure scaffold support, in work
Support is set up on word steel top can carry out Superstructure Construction, and I-steel lower space can carry out substructure construction simultaneously.
For ensureing structural strength, further scheme is, the termination being positioned at every I-steel inside described Vierendeel girder sets
Have three circular holes, the termination of every described I-steel have three connected to drawing reinforcing bar.
For ensureing that platform has a good buffering soundproof effect, further, described bar-mat reinforcement top steel plate top also
It is arranged at intervals with the lumps of wood, completely spreads on described lumps of wood top and be fixed with bamboo slab rubber.
For ease of carrying out spacing to superstructure support, the upper surface of described I-steel is fixed with vertically arranged spacing
Reinforcing bar.Limit steel bar can be as the stopping means of superstructure support.
For ease of construction, it is ring-type to the two ends drawing reinforcing bar, is connected with described positive silk hook drawing reinforcing bar.
Described ultra-large type boundling polygon coal bunker group's Multifunctional partition is from the construction method of operation platform, and it uses following step
Rapid construction:
(1) by I-steel by design size machine-shaping, and magnetic drill is at one end used to get out circular hole；
(2) will be to drawing reinforcing bar by design size machine-shaping；
(3) during the colligation of Vierendeel girder joint bar, on beam, surveying and locating goes out I-steel particular location, pre-buried slotting in I-steel position
Muscle, and prevent joint bar from conflicting with I-steel position；
(4) after Vierendeel girder pours, I-steel is laid by setting-out position, by I-steel and pre-doweling firm welding；
(5) between described I-steel, surface uses reinforcing bar to be welded as a whole thereon；
(6) utilize to draw reinforcing bar and between positive silk I-steel inside described Vierendeel girder to the centre being pulled in Vierendeel girder
Region forms bar-mat reinforcement, and makes drawing reinforcing bar uniform stressed by screwing down positive silk；
(7) on described bar-mat reinforcement, completely spread steel plate, and by Interal fixation, form isolation operation platform.
Further, described is φ 14 reinforcing bar to drawing reinforcing bar.
For ensureing that platform has good buffering soundproof effect, further, between the steel plate top on described bar-mat reinforcement top
Every arranging the lumps of wood, completely spread bamboo slab rubber on described lumps of wood top, and bamboo slab rubber is nailed together with the lumps of wood.
The invention has the beneficial effects as follows: the present invention utilizes I-steel, positive silk, reinforcing bar, steel plate composition isolation operation platform,
Intensity is high, good stability, simple structure, and easy construction can not only meet tall and big silo structure construction needs, and can save
Save the costs such as substantial amounts of human and material resources, and the isolation platform formed can make superstructure construct with substructure simultaneously, energy
Enough shortening the construction period, it is ensured that construction speed, and construction safety coefficient is high, the present invention can effectively substitute full framing or the biggest
Setting up of shaped steel structure isolation, improves construction speed and construction safety coefficient.Simple structure of the present invention, principle are understandable, draw materials conveniently,
With low cost, there is higher practicality.
