Embodiment
With reference to embodiments and its accompanying drawing illustrates further to the present invention.
Embodiment 1
1. there is top cover steel feed bin top frame platform formwork measure
For there is the frame superstructure of top cover steel feed bin, in construction steel feed bin, it is 100mm to have calculated crossbeam beam bottom distance steel feed bin top cover gap.
According to original design top cover steel feed bin after installing, its top framework platform structure of constructing when, template support system includes very heavy Top bearings 7, sensor support base 8, limiter bearing 9 can only frame on the top cover for having top cover steel feed bin.If direct frame on the top cover of steel feed bin, is waited after top concrete frame platform structure conserves, template support system by it is concrete structure pressed inflexibly, will be unable to the demoulding and remove.
Referring now to Fig. 2-4, Fig. 2 is the A-A sectional views in Fig. 1, and Fig. 3 is the enlarged drawing at P positions in Fig. 1, and it is 25mm to illustrate former design gaps, and Fig. 4 is another enlarged drawing at P positions in Fig. 1, is illustrated through making former design gaps increase to 33mm from 25mm using inclined sizing block group.
The demoulding is difficult after the method integrally jacked in advance using steel feed bin is solved the problems, such as.Every group of bearing is first included into very heavy Top bearings 7, sensor support base 8 as requested, limiter bearing 9 is installed on 16.3m platforms, and one group of 200 × 110 inclined sizing block group 10 is used on each limiter bearing, and former design gaps 25mm increases 8mm is reached into 33mm in advance.
By pre-adjusting bearing absolute altitude, steel feed bin is improved into 8mm, then the real space size of steel feed bin top cover to top concrete crossbeam bottom space is 100-8=92mm.It is 12mm thick, flitch 80 × 50mm of specification from the specification of template 12, and is just 92mm, so template can be placed directly on the steel feed bin top cover of top completely.
Supporting is completed as stated above, after+21.8m the platform constructions of steel feed bin and top are complete, steel feed bin top cover, middle concrete crossbeam, concrete platform will form the space of a closing, personnel, which cannot be introduced into this closing space, to complete to tear frame operation open, and the template of the landing slab bottom in this space and support will be unable to remove.Therefore, before concrete platform of constructing, linked up with design, increase by 600 × 600mm maintenance holes 1 on 21.8m platforms, operating personnel enters from newly-increased maintenance hole treats form removal job space.
2. there are the demoulding of top cover steel feed bin top frame platform, form removal measure
Fig. 5 is the enlarged drawing at Q positions in Fig. 1, illustrates steel feed bin top frame platform formwork schematic diagram, and Fig. 6 is another enlarged drawing at Q positions in Fig. 1, illustrates the demoulding of steel feed bin top frame platform, form removal schematic diagram.
After the completion of having the maintenance of the concrete frame platform construction at the top of top cover steel feed bin, with the whole steel feed bin of 4 30t~50t jack stands, take out the inclined sizing block group that steel feed bin is improved to 8mm in advance, plus the 25mm gaps of design itself, after steel feed bin is put down above the spacing bearing, for top crossbeam with forming 33mm spaces at the top of steel feed bin, the space is a little although narrow and small, and operation is more difficult but is enough to take off the template under concrete crossbeam.
Operating personnel enters from newly-increased maintenance hole treats form removal job space.After form removable, it is covered in using removable cover on hole.Then again with jack by steel feed bin top to design elevation of top+21000, install gravity sensor.
The present invention has substantive distinguishing features and significant technological progress, the present invention's has top cover steel feed bin top frame platform formwork, release method, the arrangement and method for construction integrally jacked in advance using steel feed bin, use device is simple in construction, sets up conveniently, the construction quality that steel feed bin integrally jacks in advance is safe and reliable, solve the problem that template support system can not be stripped dismounting, also accelerate project progress, reduce engineering cost.
Above example is used for illustrative purposes only, rather than limitation of the present invention, person skilled in the relevant technique, without departing from the spirit and scope of the present invention, can also make various conversion or change.Therefore, all equivalent technical schemes should also belong to scope of the invention, should be limited by each claim.
