Hydraulic slip-form construction method of reinforced-concrete straight-drum high-rising building

Abstract

The invention discloses a hydraulic slip-form construction method of a reinforced-concrete straight-drum high-rising building. The hydraulic slip-form construction method specifically comprises the following steps of: a) building a temporary platform; b) installing an opened frame; c) installing enclosing rings; d) assembling a template; e) adjusting the template and the enclosing rings; f) installing an inner platform and an outer platform; g) installing jacks and supporting rods; h) inspecting the whole system and constructing a first-section slip form; i) improving an inner lifting frame and an outer lifting frame; and j) normally climbing a slip-form system. The hydraulic slip-form construction method has the advantages that the inner platform, the outer platform, the inner lifting frame, the outer lifting frame, the opened frame and the template enclosing rings of the slip form system adopt scaffold steel pipes and steel fasteners, simultaneously the connecting mode with the steel pipe fasteners is adopted between the template enclosing rings and the opened frame, between the opened frame and the inner and the outer platforms, and between the inner and the outer platforms and the inner and the outer lifting frames, thus the cost is low, the construction progress is high, the construction period of the engineering is shortened, simultaneously the processing and welding on site are reduced and further the environmental pollution is reduced.

Description

technical field [0001] The invention relates to a construction method of a reinforced concrete towering structure, in particular to a hydraulic sliding form construction method of a reinforced concrete straight cylinder towering structure. Background technique [0002] Common high-rise reinforced concrete structures include cylindrical loading warehouses, chimneys, silos, shafts, hyperbolic cooling towers, etc. At present, many high-rise buildings are constructed with sliding formwork, especially the straight high-rise structures of reinforced concrete mostly use hydraulic sliding formwork construction techniques, such as Figure 6 As shown, the inner operating platform, outer operating platform, open-shaped frame, and inner and outer rings of the formwork in the sliding form system are generally steel structures, and the gaps between the open-shaped frame and the formwork ring, inner and outer platform rings, railings, and inner and outer platform hangers Connections are we...

Problems solved by technology

The disadvantages of adopting the existing construction technology are: (1) because the frequency of undertaking similar projects in the construction of high-rise structures is very low for general construction units, the operating platform, open frame, formwork enclosure, and inner and outer platform enclosures processed with section steel are very low. The rings, railings and hangers are almost disposable, and the construction cost is relatively high; (2) the existing technology is difficult to construct, and the production and installation requirements are high, so professionals must be responsible for the construction; (3) the existing technology has many on-site processing parts and installation The workload is heavy. All the open-shaped steel frames, steel enclosures, platforms and hangers need to be processed and installed on-site. The construction period is long and the welding workload is heavy. At the same time, the large amount of welding causes great environmental pollution.
