Embodiment 1

[0087] The super-high and super-strength RC chimney trapezoidal formwork buckle joint digital formwork construction method provided in this embodiment includes the following steps:

[0088] (1) Installation and construction of scaffolding and derrick, inner double-layer platform and lifting system

[0089] Mantang scaffolding and derrick erection construction

[0090](1) Mantang scaffolding is used, and the total height of the internal vertical lifting derrick is 130m, all of which are erected with construction steel pipes and fasteners as the construction progresses. The spacing is 1.5m, and it is erected according to the ratio of the inner diameter of the chimney. The range of scaffolding in the whole hall gradually decreases with the change of the internal size of the chimney; when erecting horizontal steel pipes, extend the surrounding 4 steel pipes every 10m at the chimney corbels in the height direction , until the two ends are anchored into the concrete wall of the tub...

[0156] The economic benefits of this construction method

[0157] (1) Due to the integration and change of the construction process, the construction is convenient. While speeding up the construction progress, saving construction costs and shortening the construction period, it also prolongs the service life of the super high and super strong RC chimney.

[0158] (2) The trapezoidal buckle digital assembly formwork system adopted is advanced in technology, labor-saving and easy to operate. During the construction, digital assembling and other techniques of fastening molds are adopted, which saves labor, shortens the construction period, improves the quality, and reduces the cost of later repairs and repairs. The belt-type formwork on the outside of the chimney eliminates the safety hazard of the external formwork support during construction, reduces labor intensity, speeds up the construction progress, and shortens the construction period. A total of 253,000 yuan of direct pr...

example

[0168] "Ultra-high and super-strong RC chimney trapezoidal fastening digital construction method" was applied to the chimney project of Jiaonan Yitong Thermal Power Newly Added Heating Boiler Expansion and Upgrading Project, with a total height of 120m and a total concrete engineering volume of 1456m 3 . The structural form is: reinforced concrete towering structure. The building category is a first-class structure with a design service life of 30 years.

[0169] Implementation Effect

[0170] The chimney project of Jiaonan Yitong Thermal Power’s new heating boiler expansion and upgrading project is located at No. 188, Qingdao North Road, Huangdao District, Qingdao. The foundation of the construction site is located on strongly weathered granite, with a height of 120m, and the construction is difficult.

Abstract

The invention discloses a construction method of an ultrahigh and ultra-strong RC chimney trapezoidal template fastening digital assembling mould. The construction method comprises the following steps: (1) installation and construction of a scaffolding, a derrick, an inner double-deck platform and a lifting system; (2) production and installation of the trapezoidal template; and (3) dismantling construction of an inner frame. The construction method is simple and rapid in construction and convenient to control quality. The technologies of digital assembling of fastening section mould and the like are adopted in construction, labor force is saved, building time is shortened, quality is improved, and late repairing cost and back repairing cost are reduced. Belt-type mold locking is arranged on the outer side of a chimney, security risks of supporting an outer mould in construction is eliminated, labor intensity is reduced, construction schedule is speeded, and building time is shortened. Construction direct cost is saved by a total of 253,000 yuan, and economic benefits are significant. The key technology of the construction method is mature and reliable, the flatness of a structure is improved, the appearance quality is improved, and the reliability of the structure is ensured; and construction is environmentally friendly and clean, the customer satisfaction is good, and good social benefits are achieved.

Description

technical field [0001] The invention relates to a super-high and super-strong RC chimney trapezoidal formwork buckle joint digital formwork construction method, which belongs to the technical field of building construction. Background technique [0002] As one of the essential equipment for hot blast stoves, chimneys are often used in industrial projects. However, the traditional construction methods of reinforced concrete chimneys are difficult to meet the high-standard construction quality requirements. Therefore, it is very necessary to study the safe and environmentally friendly construction methods of reinforced concrete chimneys. [0003] For the construction of reinforced concrete chimneys, from the perspective of engineering effect and economy, there are different processing methods for the erection and lifting of the construction platform, the support and fastening of the inner and outer formwork, etc. Under the constrained conditions of construction quality, cons...
