Large-span silo roof construction platform and erecting method

Abstract

The invention relates to the technical field of buildings, and discloses a large-span silo roof construction platform. The large-span silo roof construction platform comprises bottom columns, middle columns, top columns, bailey trusses, connecting parts, a base plate and a formwork scaffold; and all the structures are independently prefabricated and spliced and installed on a construction site to form an integral structure. According to the large-span silo roof construction platform, the roof high-altitude operation platform is installed in a segmented mode and fast and convenient to erect, construction cost consumption can be effectively reduced, construction operation convenience is improved, the bottom columns, the middle columns and the top columns are used for supporting the bailey frames together with silo walls, stress of the silo walls is shared, the construction platform is high in structural stability, the multiple rows of bailey frames are arranged, the self weight of a single row of bailey frames is small, so that hoisting and mounting are convenient, connection among all structures is stable and reliable, the safety is good, the construction platform can adapt to various large-span structures and high-altitude construction, and the application range is wide. The invention further provides an erecting method of the large-span silo roof construction platform. The erecting method has the advantages of being high in erecting efficiency, good in safety and the like.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a large-span silo roof construction platform and an erection method. Background technique [0002] With the development of the economy, in order to meet the demand for storage, more and more large-scale silo structures appear, and the height and span of the silo structures continue to increase, which also increases the difficulty of roof construction on the top of the silo structures. [0003] The roof construction of the existing silo structure usually adopts methods such as erecting floor-to-ceiling scaffolding and erecting an operating platform at high altitude. The method of setting up floor-to-ceiling scaffolding for high-altitude formwork construction is too high due to the large amount of scaffolding, and it is difficult to guarantee the safety of the scaffold when the scaffolding height is high, so the number of times this method is used is gradually decreas...

Problems solved by technology

However, in the actual operation of this method, if the roof of a large-span concrete silo structure is encountered, the load-bearing main girders such as section steel or Bailey frames need to have greater strength, rigidity and stability, which causes the load-bearing main girders such as section steel or Bailey frames A larger section can meet the force requirements. In order to meet the force requirements, it is necessary to increase the type of steel load-bearing main girder or change the single-row single-layer Bailey frame load-bearing main girder into multiple multi-layer Bailey frame load-bearing main girders and Reinforced Bailey frame load-bearing main girder, the above treatment methods lead to an increase in the weight of the load-bearing main girder, which greatly increases the difficulty of construction, especially the high-altitude hoisting of the load-bearing main girder, the commonly used lifting tool on the construction site is the tower crane, and the lifting capacity of the tower crane It is relatively limited, and often cannot meet the high-altitude hoisting requirements of large cross-section load-bearing girders
