Problems solved by technology

[0003] However, the construction technology of some links in the existing traditional construction method is relatively old, resulting in low construction efficiency. Therefore, it is urgent to study and optimize the construction plan of the slip form, so as to speed up the construction progress and ensure the quality of the project.

Embodiment

[0063] This embodiment discloses a specific sliding form construction method for a large-diameter silo. The specific steps are as follows: installation of steel bars on the silo wall → sliding form installation, debugging → concrete pouring (concrete trimming, surface plastering) → sliding form lifting (concrete curing) → Concrete pouring (concrete trimming, surface plastering) → sliding form lifting (concrete curing) → concrete pouring (repeat the above 2 tasks until the warehouse wall sliding form is completed) → sliding form equipment removal → concrete curing.

[0064] Among them, in the installation step of the steel bar on the tank wall, the steel bar binding construction is carried out before the sliding form device is assembled, the steel bar on the tank wall is bound to a height of 1.3 meters, and the vertical steel bar is thrown out, and the joints are staggered. In the normal sliding stage of the sliding form, every time the height is raised (200-300mm), the warehous...

Abstract

The invention discloses a construction method of a sliding formwork for a large-diameter silo. The construction method comprises the steps that 1, silo wall steel bar mounting is conducted; 2, slidingformwork mounting and debugging are conducted; 3, concrete pouring is conducted; 4, sliding formwork lifting is conducted, wherein tank wall sliding formwork lifting is divided into three stages, namely primary sliding, normal sliding rising and tank wall top formwork sliding rising; 5, concrete pouring and sliding formwork lifting are repeated till the silo wall sliding formwork is completed; 6,sliding formwork device dismantling is conducted; and 7, concrete curing is conducted. According to the construction method, only one set of formworks is used, the formworks and an operating platformare lifted through a hydraulic jack, formwork supporting and scaffold setting up are not needed any longer, and thus the formworks, scaffold materials and manual work can be greatly saved; continuousoperation is kept during construction, various working procedures are simplified, the sections of the formworks do not need to be mounted and dismounted completely, and thus the construction speed ishigh; and concrete adopts continuous pouring, construction joints can be reduced, and integrality of a building can be ensured.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a sliding form construction method for a large-diameter silo. Background technique [0002] The construction method of hydraulic sliding formwork is one of the construction methods of cast-in-place concrete engineering. It began in the early 1960s in China and has a history of nearly 50 years. This construction technology has been widely used in concrete and reinforced concrete structures. : Tube wall structure (including chimney, prilling tower, water tower, silo, oil tank, bridge pier, shaft wall, etc.); frame structure (including bent frame, column, etc.); wall panel structure (high-rise building construction). The effect is particularly remarkable when it is applied to the construction of tube-wall structures and high-rise buildings. It not only saves templates, scaffolding and labor, but also speeds up the construction and ensures the quality of the project. ...
