Space pipe frame pre-assembly cycle flip method

Abstract

The invention discloses a circulatory inverted assembling method for spatial pipe rack pre-assembly. The method includes the following steps: drawing a skeleton map of a spatial pipe rack; selecting five adjacent main pipes, dividing the five main pipes into two groups, and respectively projecting the two groups of main pipes and branch pipes into a same plane; setting up two platforms; spraying powder to and setting out projections of the two groups of main pipes onto the two platforms; making corresponding real main pipes, sequentially numbering the real main pipes as A', B', C', D' and E', arranging stand columns and support frames on one platform, horizontally placing A' and B' on the support frames and the platform, assembling the branch pipes between A' and B', fixing by spot welding and completing a first pipe rack; horizontally lifting the first pipe rack, horizontally placing C' on the platform, assembling the branch pipes between B' and C', and detaching C' and the branch pipes; assembling C' and D' on the other platform, and completing a second pipe rack; repeating the steps to realize pre-assembly of the spatial pipe rack. By the method, precision of field installation can be effectively guaranteed, and safety coefficient is improved.

Description

technical field [0001] The invention belongs to the field of building construction, and in particular relates to a pre-assembled cycle flipping method for space pipe racks. Background technique [0002] Due to the advantages of light weight, beautiful appearance and good bearing capacity, space steel structure pipe frame is widely used in more and more architectural designs. However, its unique structural form has higher and higher requirements for manufacturing units. , in order to ensure product quality and on-site installation accuracy, it is necessary for such structures to be pre-assembled once in the factory. However, at present, there is no mature assembly technology for this type of structure in the industry to learn from. If the traditional pre-assembly method of erecting a full house of scaffolding is adopted, not only the economic benefit is low, the construction period cannot be met, but also the requirements for measuring equipment are high.

However, at present, there is no mature assembly technology for this type of structure in the industry to learn from. If the traditional pre-installation method of erecting scaffolding is used, not only the economic benefit is low, the construction period cannot be met, but also the requirements for measuring equipment are relatively high.
