Description
Technical field
The invention belongs to the construction and installation technical field, particularly a kind of major diameter steel storehouse divides band to make the job practices that the inverted order jacking is installed, and is applicable to that various steel warehouses are as the industry that stores body and the construction of public works.
Background technology
Major diameter steel storehouse (diameter 〉=6m ,≤30m) in various industrial projects, be widely used as finished product or raw material storage equipment, in other crops store, use is arranged also.
The characteristics in major diameter steel storehouse are that component volume is big, Heavy Weight.Conventional job practices is generally integral manufacturing, installation.Need take very big processing place in the conventional job practices manufacturing process; Transportation and installation need enough big lifting and haulage device; For preventing deformation of members in lifting, the transportation, need during making a large amount of reinforcement measure members such as steel plate bar to be set in warehouse inside, increased lifting, hauled weight again for this reason.Therefore the construction of conventional method major diameter steel storehouse needs to drop into great amount of manpower and material resources and plant equipment.
To take construction area big in order to solve conventional job practices, drops into problems such as plant equipment is many, and the spy develops major diameter steel storehouse and divides band to make, the job practices that the inverted order jacking is installed.This job practices has been done to describe in detail to job practicess such as the making in major diameter steel storehouse, radian control, warehouse connection, jacking installations and has been set forth, and has formed reasonable, the feasible construction technology of a cover.
Summary of the invention
The object of the present invention is to provide a kind of major diameter steel storehouse to divide band to make, the job practices that the inverted order jacking is installed.Adopt and divide band to make, solved the making of major diameter steel storehouse and taken the construction plant, the problem of large-scale lifting, Transport Machinery is used in transportation; The problem that has solved installation process use large-scale hoisting machinery is installed in the inverted order jacking; Solved radian centering when dividing the band assembly unit simultaneously, cone construction, the problems such as processing of integral jacking node.
The method applied in the present invention is as follows:
1, major diameter steel storehouse is made of major diameter steel storehouse straight section part and major diameter steel storehouse conical section.According to the width of used steel plate major diameter steel storehouse straight section part and major diameter steel storehouse conical section level being divided into strip makes.
2, set up moulding bed with Φ 48mm steel pipe on concrete platform, major diameter steel storehouse conical section divides band making, assembly unit on moulding bed.
3, major diameter steel silo wall installed inside jack-up system on concrete platform.Jack-up system constitutes by supporting steel column, 1# jack and jacking steel plate.Jacking is supported to adopt and is supported steel column, and jacking power adopts the 1# jack.Support steel column by built-in fitting and concrete platform welding.
4, major diameter steel storehouse conical section is made and finished, and is behind the height of jack-up system with a major diameter steel of major diameter steel storehouse conical section jacking storehouse straight section strip, with interim support that major diameter steel storehouse conical section is temporary fixed.
5, behind the height of a straight section strip of major diameter steel storehouse cone jacking, on concrete platform top, major diameter steel storehouse conical section lower space is divided band assembly unit major diameter steel storehouse straight section strip.During major diameter steel storehouse straight section strip assembly unit, utilize predetermined fixed on concrete platform to look for arc chock control steel storehouse radian be 180 °.The straight section strip assembly unit of major diameter steel storehouse is to utilize the butt joint steel plate locking of 2# jack with major diameter steel storehouse straight section strip two joint ends, cooperates jack-up system and look for the arc chock to be assembled into cylindric.
6, straight section strip assembly unit in major diameter steel storehouse finishes, and the angle steel of usefulness straight section strip top, major diameter steel storehouse welding and reinforcing bar anchor head carry out major diameter steel storehouse conical section and major diameter steel storehouse straight section strip temporary fixed as auxiliary part.After major diameter steel storehouse straight section part and the major diameter steel storehouse conical section firm welding, utilize jack-up system once more, the good major diameter steel of jacking assembly unit storehouse straight section part and major diameter steel storehouse conical section.
7, other major diameter steel storehouse straight section strip job practicess are with step 6, up to intact last band straight section strip of jacking.
8, at last the bolt hole on the base of major diameter steel storehouse is aimed at pre-buried major diameter steel storehouse anchoring bolt, placed bottom, major diameter steel storehouse base, with base and major diameter steel storehouse firm welding, the major diameter steel storehouse anchoring bolt of fastening good base.
Major diameter steel of the present invention storehouse is adopted to divide and is with preparation method, and the installation of major diameter steel storehouse is to utilize jack-up system employing inverted order mounting method from top to bottom.
The invention has the advantages that:
The finished bin job practices is compared with the finished bin job practices of routine, and working procedure is simple, adopts common construction machinery construction, ubiquity on the construction tool market; Do not use large-scale lifting, Transport Machinery, save construction cost; Make and install and to carry out simultaneously, increase construction speed; Make, be installed in major diameter steel bin location and not limited by the construction plant; Reduce a large amount of work high above the ground simultaneously, reduced the generation of site safety accident.
