Cast-in-place concrete tower with prefabricated spatial steel bar truss formwork and construction method of cast-in-place concrete tower

Abstract

The invention discloses a cast-in-place concrete tower with a prefabricated spatial steel bar truss formwork and a construction method of the cast-in-place concrete tower. The cast-in-place concrete tower comprises the spatial steel bar truss formwork and concrete cast into the spatial steel bar truss formwork in place, and is characterized in that the spatial steel bar truss formwork is a disposable prefabricated formwork, is formed by splicing a plurality of spatial steel bar truss formwork units and is in a cylinder shape; each spatial steel bar truss formwork unit is of an arc-shaped sheet structure and comprises reinforcing bars in the middle and disposable steel formworks attached to the inner and outer sides of the reinforcing bars respectively, wherein the reinforcing bars comprise an inner layer of evenly-arranged vertical stressed steel bars, an outer layer of evenly-arranged vertical stressed steel bars, horizontal stressed steel bars used for tying the vertical stressed steel bars on the same layer, and tie stirrups arranged in a radial mode and used for tying the inner layer of vertical stressed steel bars, the outer layer of vertical stressed steel bars and the horizontal stressed steel bars at the same time. By adopting the technology, it is only needed to install the spatial steel bar truss formwork in a hoisting mode in site construction, the hoisting weight is greatly reduced, the needed crane tonnage is greatly reduced, and the construction cost is greatly reduced.

Description

Technical field [0001] The invention relates to the technical field of construction of cast-in-place concrete wind power generation towers, in particular to a cast-in-situ concrete tower of a prefabricated spatial steel bar truss template and a construction method thereof. Background technique [0002] The prefabricated segments of the precast concrete wind power tower are relatively large, and the weight of a single piece is generally 30 to 60 tons. The construction site requires a thousand-ton crane to hoist the prefabricated power tower section in place, resulting in extremely high lifting costs and uneconomical. If the cast-in-place concrete tower is used, it will face the problems of high-altitude formwork and high-altitude binding of steel bars. The construction period is very long and the construction is difficult, resulting in high construction costs. Summary of the invention [0003] The purpose of the present invention is to provide a cast-in-place concrete tower of pref...
