Construction method of major diameter reinforced concrete silo and device for conical shell construction

Abstract

The invention relates to a construction method of major diameter reinforced concrete silo and a device for conical shell construction. The construction method of major diameter reinforced concrete silo comprises that the rigid platform used in silo wall construction is used in the supporting platform of the cone shell construction on the top of silo, steps of removing the rigid platform and reconstructing the supporting platform are avoided, the construction period is shorten, the cost is saved, and the good economic benefit is achieved; unloading wireropes are connected between the rigid platform and conical shell moulds, and the supporting load of the rigid platform can be reduced to a certain extent; auxiliary wireropes can support carriers for center supporting frames to play a role ofstabilizing the center supporting frames; in the construction of the silo wall, a slip form is subjected to taper adjustment by installing an enclosure, when the taper of an inner formwork is 0.3%, the inner formwork is tilted to the outside of the silo, when the taper of an external framework is 0.2%, the external framework is tilted towards the interior of the silo, the inner framework and theexternal framework are corrected, and the accuracy of the template is ensured, at the same time, sliding and demoulding of the slip from are convenient.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a construction method for a large-diameter reinforced concrete silo and a construction device for a cone shell. Background technique [0002] As a storage facility, reinforced concrete silos are widely used in coal, electric power, mining, chemical, grain storage and other industries. With the rapid development of my country's social economy, the diameter of the silo structure is getting larger and larger, the headroom of the reinforced concrete silo top conical shell is super high, the shell plate is super heavy, and the span is super large, which requires the original construction technology to continue to make breakthroughs in this area. To meet the ever-changing requirements of the construction market. The raw coal warehouse project of Qinghai Mining Coal-based Polygeneration Coal Preparation Plant undertaken by our company has 3 warehouses combined, with a sing...

The Chinese patent with the patent number ZL201210419350.2 discloses a construction method for a large concrete granary, which is also the construction of a utilization rate sliding form platform. The formwork construction technology also needs to use the traditional construction technology. After the construction of the silo wall is completed, the sliding form and related equipment need to be removed, which consumes a lot of man-hours and manpower. When sliding the formwork, there is friction between the formwork and the poured concrete. , not easy to demould
