Specific embodiment
With reference to embodiments and its attached drawing further explains 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, crossbeam beam bottom distance steel material has been calculated
Silo roof lid gap is 100mm.
According to original design top cover steel feed bin after installing, construction upper part framework platform structure when, template support system
System include jacking bracket 7, sensor support base 8, limiter support 9 can only frame on the top cover for having top cover steel feed bin.If straight
Frame is connect on the top cover of steel feed bin, after waiting tops concrete frame platform structure to conserve, template support system is by concrete
What structure was pressed inflexibly, it will be unable to demoulding and remove.
It is the A-A cross-sectional view in Fig. 1 referring now to Fig. 2-4, Fig. 2, Fig. 3 is the enlarged drawing at the position P in Fig. 2, illustrates that original is set
Meter gap is 25mm, and Fig. 4 is another enlarged drawing at the position P in Fig. 2, illustrates that inclined sizing block group is used to make former design gaps from 25mm
Increase to 33mm.
It is difficult to demould after being solved the problems, such as using the method that steel feed bin integrally jacks in advance.First as requested by every group of support packet
Jacking bracket 7, sensor support base 8 are included, limiter support 9 is installed on 16.3m platform, is used on each limiter support
Former design gaps 25mm increase 8mm is reached 33mm in advance by one group of 200 × 110 inclined sizing block group 10.
By pre-adjusting support absolute altitude, steel feed bin is improved into 8mm, then steel feed bin top cover to top concrete crossbeam bottom
The real space in space is having a size of 100-8=92mm.Select 12 specification of template thick for 12mm, flitch 80 × 50mm of specification, and just
For 92mm, pushed up on steel feed bin top cover so template can be placed directly in completely.
According to the above method supporting complete, after+21.8m the platform construction of steel feed bin and top is complete, steel feed bin top cover, in
Between concrete crossbeam, concrete platform will form a closed space, personnel, which cannot be introduced into, to complete to tear frame operation open in this enclosure space, this is empty
Between platform board bottom template and support will be unable to remove.Therefore, it before concrete platform of constructing, is linked up with design, it is flat in 21.8m
Increase by 600 × 600mm on platform and overhaul hole 1, operating personnel enters from newly-increased maintenance hole to demoulding job space.
2. having the demoulding of top cover steel feed bin top frame platform, demoulding measure
Fig. 5 is the enlarged drawing at the position Q in Fig. 2, illustrates that steel feed bin top frame platform formwork schematic diagram, Fig. 6 are Q in Fig. 2
Another enlarged drawing at position illustrates the demoulding of steel feed bin top frame platform, demoulding schematic diagram.
After the completion of having the concrete frame platform construction maintenance at the top of top cover steel feed bin, with 4 30t~50t jack stands
Entire steel feed bin takes out the inclined sizing block group that steel feed bin is improved to 8mm in advance, in addition the gap 25mm of design itself, puts down steel material
Storehouse forms the space 33mm after limiting above support at the top of top crossbeam and steel feed bin, the space is a little although narrow, operates
It is more difficult but be enough to take off the template under concrete crossbeam.
Operating personnel enters from newly-increased maintenance hole to demoulding job space.After form removable, using removable cover
It is covered on hole.Then again with jack by steel feed bin top to the elevation of top+21000 of design, gravity sensor is installed.
The present invention has substantive distinguishing features and significant technological progress, and of the invention 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 structure is simple, sets up conveniently, steel feed bin
The whole construction quality jacked in advance is safe and reliable, solves the problems, such as that template support system can not demould dismounting, also accelerates work
Cheng Jindu, engineering cost is reduced.
Above embodiments are used for illustrative purposes only, rather than limitation of the present invention, the technology people in relation to technical field
Member, without departing from the spirit and scope of the present invention, can also make various transformation or variation.Therefore, all equivalent
Technical solution also should belong to scope of the invention, should be limited by each claim.
