Description

Technical Field

[0001] This utility model relates to the field of power plant construction engineering technology, specifically a scaffold-free cylindrical structure construction platform. Background Technology

[0002] In the field of thermal power plant construction, there are many cylindrical structure buildings, with ash silos being a typical example. Conventional construction methods involve erecting full-span scaffolding both inside and out, in conjunction with standardized steel formwork. However, the following defects exist during construction:

[0003] 1. Numerous joints in the formwork result in poor surface smoothness of the concrete, requiring subsequent repairs;

[0004] 2. Construction on upper and lower floors interferes with each other, and the efficiency of overlapping work processes is low;

[0005] 3. Traditional diagonal bracing reinforcement methods have poor stability and are prone to displacement deviation. Utility Model Content

[0032] The working principle of this utility model:

[0033] Anchoring unit structure

[0034] like Figure 2 As shown, the core components of the anchoring unit are climbing cone 1 and climbing cone 2, both of which are designed with threaded structures on the inside and outside. Climbing cone 2 adopts a mirror arrangement, and the inner side is connected by connecting rod 3. The size of connecting rod 3 is adapted to the side wall thickness of the cylinder to be poured; the outer sides of climbing cone 1 and climbing cone 2 are effectively connected to the working platform and steel formwork 7 by bolts.

[0035] First floor concrete pouring

[0036] like Figure 3 As shown, climbing cone 1 and climbing cone 2 are pre-embedded inside the steel formwork 7. Climbing cone 1 is fixed to the steel formwork 7 with anchor 4, and climbing cone 2 is symmetrically distributed. The two are connected by connecting rod 3, which acts as a tie bolt to enhance the stability of the structure. After the steel formwork 7 is placed and the reinforcement operation is completed, the first layer of concrete is poured.

[0037] Second layer of concrete pouring

[0038] like Figure 4 As shown, after the second layer of steel reinforcement binding is completed, steel formwork 7 is placed; the bottom of steel formwork 7 is fixed to the second climbing cone 2 pre-embedded in the first layer by connecting bolts 6 to ensure the stability of steel formwork 7; the first climbing cone 1 and the second climbing cone 2 are arranged on the top of steel formwork 7, and after the reinforcement process is completed, the second layer of concrete is poured.

[0040] like Figure 5 As shown, the tripod 8 is fixed to the No. 1 climbing cone 1 pre-embedded on the second layer with bolts, the third layer of steel bars is tied, the No. 1 climbing cone 1 and the No. 2 climbing cone 2 are pre-embedded, the steel formwork 7 is placed and the reinforcement operation is completed, and the third layer of concrete is poured.

[0041] Assembly line operation stage

[0042] like Figure 6As shown, after the completion of the three-layer concrete pouring work, the assembly line operation stage begins. The processing platform is formed by assembling the finishing layer, working layer 17, and formwork reinforcement layer 18. The platform is connected using the first-layer pre-embedded climbing cone 1 to ensure overall stability. The steel formwork 7 is connected below by the second-layer pre-embedded climbing cone 2, while the first-layer and second-layer climbing cones 1 and 2 are pre-embedded above it. The second-layer climbing cone 2 is connected via connecting rod 3.
