Description
Technical field
The utility model relates to a kind of formwork system in building operations research field, particularly a kind of formwork system of silo inner funnel.
Background technology
Along with the socioeconomic fast development of new China and scientific and technical rapid progress, the application of silo in all parts of the country is from grain, building materials, metallurgy, coal to power industry, more and more extensive, the scale of silo is built larger and larger, and application form has also had the multiple combination such as single storehouse, group storehouse.
Along with the enhancing of China's economic strength, the needs of social development and environmental protection development, growth in the living standard impels the diversified development of life further, and warehousing industry achieves swifter and more violent development in recent years.Silo structure is as the storage structures of the three-dimensional of advanced person, and as an important component part of warehousing system, its corresponding theoretical research, design concept, construction technology also need perfect further.
Concrete silo structure be a kind ofly be usually used in having grain in reserve, the silo structure form of the bulk food such as feed, coke, cement, industrial material, this class formation all has storehouse inner funnel structure usually, facilitating weighing, turn over storehouse, sterilization, the work such as cleaning.For satisfied use needs, this class formation all has higher requirement to moisture resistance, thermal insulation, tightness, insect protected, protection against rodents sparrow property etc. usually.
For ensureing that warehouse structure meets the requirement of the performances such as moisture resistance, thermal insulation, tightness, insect protected, protection against rodents sparrow property, silo structure many employings slipform process is constructed, and it is sliding to carry out sky during traditional construction of funnel method to be bulkhead construct funnel absolute altitude, then to construct funnel, start sliding after treating construction of funnel again, thus bulkhead inevitably produces constuction joint, affects functional performance.
Silo construction part waters construction of funnel construction technology funnel after adopting in recent years, bulkhead constuction joint is produced though avoid, in duration and ensure that seal achieves certain improvement, but the funnel formwork construction time is oversize affects the duration, and because of bulkhead shares, the reason such as funnel overlap joint makees funnel after not yet having colony's silo to adopt large area construction method.
The bracing frame all round victory vertical rod of the silo inner funnel of prior art generally adopts square grid shape to arrange or radiation-ring-shaped is arranged.Be not easy to the installation of cantilever tip radial main purlin when adopting square grid shape to arrange, need to increase many additional vertical rods; When adopting radiation-ring-shaped to arrange, need to intercept a large amount of short steel pipes as hoop horizontal stable rod member.Whole temporary support architecture burden, steel pipe use amount is large, and waste of material is serious, and the too intensive difficulty turn increasing workman's operation of steel tube poles, cause potential safety hazard and construction towing.
The template system of the silo inner funnel of prior art is pure steel pipe, wooden a tree, used in making timber for boats formwork system, and horizontal force primary and secondary purlin adopts steel pipe or wooden a tree, used in making timber for boats.Because funnel is conical, level time purlin need be arranged along funnel hoop, and be very limited when secondary purlin adopts when steel pipe or wooden a tree, used in making timber for boats, need to intercept a large amount of short wooden a tree, used in making timber for boats or short steel pipes, easily cause waste of material serious, set up process loaded down with trivial details, efficiency of construction is low.In storehouse, workload is large, and number of workers causes the potential safety hazard of confined space operation at most further
Concreting many employings pumping of concrete of the silo inner funnel of prior art, part adopts indigenous method plate construction technology.
