Description
Technical field
The present invention relates to storage field, be specifically related to a kind of ultra-large type building blocks steel reinforced concrete silo structure and mounting process.
Background technology
Current large-scale silo agent structure mainly contains prestressed reinforced concrete structure and steel plates of steel structure chamber structure.
Prestressed reinforced concrete structure silo: all adopt overall pile foundation, site operation difficulty is large, and foundation cost is large, and concrete consumption is large, long in time limit, and overall cost is high, and build up after rear threading material, base plate can be perplexed by the long-term internal stress that unbalance loading is brought.
Steel plates of steel structure chamber structure silo: steel silo structure barrel is thin, stand to stressed poor, easily unstability, generally be only applicable to silo, oil depot, in the time storing caking property material, easily produce knot wall, vertical load sharply strengthens, very easily UNSTABLE FAILURE, steel plates of steel structure chamber structure silo adopts overall endless belt shape pile foundation sometimes, pile foundation processing is not done in inside, cost reduces, but build up after rear threading material, the pressure that interior ring base plate and overall endless belt shape pile foundation are brought by material can, produce larger distortion, and distortion is uneven, and then cause bottom gallery distortion, have a strong impact on use.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of ultra-large type building block type steel reinforced concrete silo structure and mounting process, fully combination utilizes bearing property and the strong feature of concrete crushing resistance of steel plate, and tires out and push away lifting from bottom to up, and mounting process is simple, high safety, good economy performance, not only can the reduction of erection time, improves construction speed, also avoid silo to build up rear threading material groundwork because of material unbalance loading, and the inequality producing distortion, the problems such as impact use, thus overcome the deficiencies in the prior art.
In order to solve the problems of the technologies described above, the present invention has adopted following technical scheme: a kind of ultra-large type building blocks steel reinforced concrete silo structure is characterized as: be mainly made up of storehouse roof construction, storehouse body cylindrical shell, storehouse base plinth, wherein storehouse roof construction comprises: awning structure, central blanking barrel, spoke architecture, revolution crane span structure; Storehouse body cylindrical shell comprises: warehouse is steel reinforced concrete pillar, steel reinforced concrete pillar annular tie-beam, bulkhead outer longitudinally steel reinforced concrete channel-section steel, bulkhead outer ring steel reinforced concrete channel-section steel, bulkhead steel plate, connector etc. around; Warehouse basis comprises: basic pile, disjunctor basis etc.
Wherein, bulkhead outer longitudinally steel reinforced concrete channel-section steel, bulkhead outer ring steel reinforced concrete channel-section steel can be standard channel-section steels, can be also semicircle or other cavity structures; Steel reinforced concrete pillar can be cylinder steel pipe or rectangular steel tube or other cavity structures; Bulkhead steel plate is connected with steel reinforced concrete pillar and can also can connects with bolt with connector welding.
For by fine said structure enforcement, the present invention also provides a kind of ultra-large type building block type steel reinforced concrete silo structure mounting process: first excavation pit, do basis, border pile, pre-buried steel reinforced concrete pillar, be connected steel reinforced concrete pillar with two kinds of annular lacing wires of rigidity and elasticity respectively, top annular beam is installed, interim spoke reinforcing ring is installed, install top hydraulic jacking system simultaneously, to ready awning structure be installed in advance in bottom afterwards, revolution crane span structure, central blanking barrel, spoke architecture, annular bracket etc. carries out integral hoisting as first segment, lift while being second section height to built on stilts distance ready, second section is continued to upwards lifting after welding with first segment at the bottom of storehouse, by that analogy, by Section three, section four, wait to the last joint rigging out after silo bottom welding, so far push away on its setting position tired first segment, final section and bulkhead composite foundation plate weld, by after steel reinforced concrete pillar annular lacing wire tension, pretension, annular bracket beam fixing collar and top annular beam are welded, simultaneously by bulkhead outer ring steel reinforced concrete channel-section steel for steel reinforced concrete pillar, the outer longitudinally steel reinforced concrete channel-section steel of bulkhead and steel reinforced concrete post coupler are connected with bulkhead steel plate, after Steel Structure Installation, finally by barrel hoop, longitudinally cavity, column inner chamber, the filling concrete in cavity place such as top ring beam, spary corrosion-inhibiting coating, completion of works.
Cordwood mounting process, has saved coming into operation of on-the-spot Large-scale Hoisting equipment, has reduced the time of work high above the ground, has reduced installation cost, has shortened the duration, has strengthened construction safety guarantee.
Compared with prior art, the invention has the beneficial effects as follows:
1. overcome prestressed reinforced concrete structure silo and all adopted overall pile foundation, site operation difficulty is large, and foundation cost is large, concrete consumption is large, long in time limit, overall cost is high, and steel silo structure barrel is thin, stand to stressed poor, easily unstability, in the time that silo stores caking property material, easily produces knot wall, vertical load sharply strengthens, very easily the shortcoming of UNSTABLE FAILURE;
2. foundation excavation amount is little, reduces cost, has improved construction speed, has reduced the duration;
3. in structure: combine with steel reinforced concrete pillar and steel plate bulkhead, connect with bulkhead outer ring steel reinforced concrete channel-section steel, the outer longitudinally steel reinforced concrete channel-section steel of bulkhead, simple in structure, it is convenient to install, and greatly reduces material cost and cost of labor;
4. mounting process: bulkhead steel plate is divided into more piece, start lifting from bottom, one joint lifting one joint is installed, progressively tired pushing away, welded and installed is all carried out at the bottom of storehouse, has saved the expense that uses Large-scale Hoisting instrument, reduce the time of work high above the ground, no matter be economic performance, or safety guarantee, all gain to some extent.
