Construction method of large-diameter coal bunker flat-topping lid

Abstract

The present invention discloses a construction method of a large-diameter coal bunker flat-topping lid, which comprises the following technical processes: 1. confirming the positions of the H-shape steel and the slip-form platform, 2. pre-embedding a steel plate in the inner bulkhead of the coal bunker, 3. pre-embedding the steel lattice structural column on the bulkhead ring beam of the coal bunker, 4. lowering the slip-form platform; 5. fixing the slip-form platform; 6. welding and fixing the steel corbel of the H-shape steel, 7. fixing the H-shape steel in position; 8. reinforcing the H-shape steel; 9. installing a bunker top main-beam formwork; 10. binding the main-beam reinforcement steel bars; 11. pouring the main-beam concrete; 12. constructing the secondary beam and the roof plate; and 13. detaching the formwork and the supporting system. The construction method of the large-diameter coal bunker flat-topping lid according to the invention has the advantages of no requirement for building full hall scaffold in the bunker, high work efficiency, short construction period, low construction cost, reliably safety and remarkable economic benefit.

Description

technical field [0001] The invention relates to a building construction method, in particular to a construction method for a large-diameter coal bunker with a flat roof. Background technique [0002] At present, in the construction of large-diameter coal bunkers with flat roofs, scaffolding is used from the ground to the top of the bunker to fix the girder formwork, secondary beams and bunker roof formwork. The construction period is long, the construction cost is high, and the safety is low. Therefore, it is a technical problem to be solved at present to design a construction method of a large-diameter coal bunker with a flat roof and a cover structure with a short construction period, low construction cost, and high safety. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a construction method for a large-diameter coal bunker with a flat roof and a cover structure with short construction period, low construction...
