B, it is welded before being temporarily supported above the Φ 8200mm direct tube sections lifting of steel feed bin top in the ground assembling stage；
C, the demoulding without top cover steel feed bin top frame platform
After the completion of+21.8m absolute altitudes concrete frame at the top of top cover steel feed bin and platform construction maintenance, it is stripped from the sealing-tape machine blanking hole of feed bin top+21.8m absolute altitude platforms into scaffold formwork bracing system, and cuts off interim channel steel support, completes the demoulding.
The present invention's can also be further achieved by the following technical measures without top cover steel feed bin top frame platform formwork, release method.
Foregoing method, wherein the channel-section steel specification is 20a channel-section steels.
Foregoing method, wherein at intervals of≤1500mm between the channel-section steel.
Foregoing method, wherein the channel-section steel surface to the height of soffit is 1700mm.
After adopting the above technical scheme, the present invention's has advantages below without top cover steel feed bin top frame platform formwork, release method：
1st, supporting apparatus is simple in construction, sets up conveniently；
2nd, scaffold formwork bracing system quality safety is reliable, framework platform formwork, is convenient in demoulding；
3rd, engineering cost is reduced, the whole construction period is fulfiled ahead of schedule on the premise of safety, quality is ensured.
Brief description of the drawings
Fig. 1 is the embodiment of the present invention without top cover steel feed bin formwork temporary support structure schematic diagram；
Fig. 2 is the A-A sectional views in Fig. 1.
In figure：1 steel feed bin, 2 channel-section steels, 3 apertures, 4 sealing-tape machine blanking holes, 5 cat ladders, 6 scaffold support systems, 7 concrete girders, 8 floors, 9 templates.
Embodiment
With reference to embodiments and its accompanying drawing illustrates further to the present invention.
Embodiment 1
The present invention without top cover steel feed bin top frame platform formwork, release method, installation sets temporary support without top cover steel feed bin, the scaffold formwork bracing system needed as concrete structure construction, and upper brace framework scaffold formwork bracing system is set up in rear temporary support in place in steel feed bin, comprise the following steps：
1. without top cover steel feed bin top frame platform formwork measure
Mix ore bunkers and belong to no top cover steel feed bin due to 16, after Φ 8200mm direct tube sections lifting in steel feed bin top is in place ,+21.8m absolute altitudes the concrete frame and during platform at the top of construction steel feed bin, platform template scaffold tube will be without support impetus.
Referring now to Fig. 1 and Fig. 2, Fig. 1 is the A-A sectional views in Fig. 1 without steel lid feed bin formwork temporary support structure schematic diagram, Fig. 2 is pushed up for the embodiment of the present invention.
Scaffold formwork bracing system is set up in order to facilitate the construction of top concrete frame structure, when installation is without top cover steel feed bin 1, can not only be merely to prevent lifting from deforming and carrying out temporary support, also it need to ensure there is the scaffold formwork bracing system facility needed for concrete structure construction while preventing feed bin from deforming.The present invention's is taken after steel feed bin is in place without top cover steel feed bin top frame platform formwork, release method, and upper brace framework scaffold formwork bracing system is set up in temporary support.
5 specifications are used as [20a channel-section steels 2 are used as backing material by calculating, at intervals of 1500mm between channel-section steel, channel-section steel is welded in the top of steel feed bin 1, and temporary support is set up on the support that 5 channel-section steels are barricaded as, and temporary support is the scaffold formwork bracing system that concrete structure construction needs.Temporary support particular location, prevent feed bin from deforming and welding operability when being assembled with reference to feed bin, be arranged at middle butt weld downwards about at 300mm, from about 1700mm at the top of steel feed bin, apart from top, concrete platform beam space reaches 1100mm, it is sufficient to meets formwork and stripping operation.The height of the surface of channel-section steel 2 to the bottom surface of floor 8 is 1700mm.
The ground assembling stage before being temporarily supported above the Φ 8200mm direct tube sections lifting of steel feed bin top is welded.
2. it is stripped measure without top cover feed bin top frame platform
It after the completion of+21.8m concrete frames at the top of top cover feed bin and platform construction maintenance, can be stripped from the sealing-tape machine blanking hole of+21.8m absolute altitude platforms at the top of feed bin into scaffold formwork bracing system, and cut off interim channel steel support, complete the demoulding.
The present invention has substantive distinguishing features and significant technological progress, being solved without top cover steel feed bin top frame platform formwork, release method using temporary support measure for the present invention directly results in top concrete frame and platform formwork difficulty, the problem for being stripped can not carry out afterwards of having constructed, the present invention's has that supporting apparatus is simple in construction, sets up conveniently without top cover steel feed bin top frame platform formwork, release method, and scaffold formwork bracing system quality safety is reliable, framework platform formwork, is convenient in demoulding.
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.
