Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a support system for a conical concrete roof of a shallow silo. Background Art

[0002] At present, as the country attaches great importance to food security, a large number of silos have been built to store food. Food security is an important cornerstone for maintaining national security. In the construction of large buildings such as granaries and factory buildings, silos are widely built because of their large grain storage capacity per unit area and high degree of intelligence. The silo roof has always been the focus and difficulty of construction.

[0003] At present, high-support formwork is usually used in the construction process. It is necessary to erect super-high frames during the construction process, which is difficult to operate and time-consuming and labor-intensive. When operators are erecting frames in the warehouse, the construction environment in the cabin is small and the shape is irregular, which leads to slow erection progress and easy damage to the inner wall of the warehouse.

[0004] Therefore, it is necessary to provide a new support system for the conical concrete roof of the shallow silo to solve the above technical problems. Utility Model Content

[0012] Preferably, an oblique rod is fixedly connected to the outer side of the second vertical rod, and a pull rod is fixedly connected to the outer side of the first vertical rod.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0014] 1. By assembling the steel truss on the ground and then hoisting it to the predetermined position, the formwork frame can be set up on the silo roof. Compared with the previous high formwork, it reduces the workload and danger. It uses high-strength steel, is easy to assemble, and is assembled by bolts to achieve the formwork operation on the silo roof, which can improve work efficiency and reduce operational risks.

[0015] 2. By welding and fixing the device on the silo wall, the large-diameter silo can be constructed on the silo top. The structure is stable during the construction process, especially for silos with higher heights, which saves costs and reduces the difficulty of operation.

[0016] 3. Through the assembly of steel components, the materials used are environmentally friendly and have a high turnover rate.
