Embodiment Construction

[0027] The present invention will be described in detail below, but the implementation scope of the present invention is not limited to the following embodiments.

[0028] Such as Figure 1-Figure 5 As shown, a square chimney light aluminum alloy formwork hydraulic inversion construction method uses light aluminum alloy formwork and uses hydraulic inversion to lift the construction truss, specifically including:

[0029] After the wall construction and earthwork backfilling are completed, the light aluminum alloy formwork hydraulic pouring equipment will be assembled. See Figure 5 First set up a temporary installation platform 21, bind 2.5 meters high steel bars 20, support the aluminum alloy formwork and correct and reinforce; utilize the temporary installation platform 21 to set up an overall steel truss 1 operation platform; install the jack 7 and the climbing pole 5, the bottom of the climbing pole 5 Weld firmly with the steel bar 20, pour the first layer of concrete, a...

Abstract

The invention discloses a hydraulic reverse formwork construction method for a light aluminum alloy formwork of a square chimney. The light aluminum alloy formwork is adopted, and a construction trussis lifted in a hydraulic reverse formwork construction mode. The hydraulic reverse formwork construction method can effectively overcome the defects that the surface of concrete is prone to tension fracture, the surface of a cylinder wall slips, a platform drifts and twists and the like, the aluminum alloy formwork is one of new processes, the concrete constructed through the aluminum formwork can achieve the effect of fair-faced concrete, and the apparent quality is excellent; and the defects of platform drifting, torsion and the like are overcome through the hydraulic reverse formwork process, and the construction efficiency and safety of chimney engineering are greatly improved through the hydraulic reverse formwork construction method of the light aluminum alloy formwork.

Description

technical field [0001] The invention relates to the field of building construction and installation, in particular to a construction method for a square chimney light-duty aluminum alloy formwork by hydraulic inversion. Background technique [0002] Chimneys have a long history and are widely used in both housing construction and industrial construction. In industrial buildings, brick-built chimneys were mainly completed manually, and their height was limited to a certain extent. Now some of the chimneys have been changed to reinforced concrete. According to the requirements of environmental indicators, the height of the chimney can be higher. Of course, the higher the chimney height, the higher the technology required. [0003] At present, the sliding form construction method is widely used in chimney construction methods, and has become the mainstream construction method for chimneys for a long period of time. However, this construction method has disadvantages such as eas...
