The epicyclic assembly device is provided with a second standardized epicyclic assembly device that cooperates with itself and the first standardized body part in the groove opened on the second standardized main body part, and the first standardized epicyclic assembly device and the second standardized epicyclic assembly device cooperate with each other ; Change different lengths, widths and heights according to different needs, the overall connection structure is simple and easy to operate, the connection points are tightly connected, and the strength is high.

Description

technical field [0001] The invention relates to the field of machinery, in particular to a rapid turnaround assembled steel structure and a construction method thereof. Background technique [0002] Steel structure is a structure composed of steel materials and is one of the main types of building structures. The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of section steel and steel plates. Welds, bolts or rivets are usually used to connect components or parts. Because of its light weight and simple construction, it is widely used in large workshops, venues, super high-rises and other fields. The steel structure is easy to rust. Generally, the steel structure needs to be derusted, galvanized or painted, and it needs to be regularly maintained. The characteristics of steel are high strength, light weight, good overall stiffness, and strong resistance to deformation, so it is especially suitable for the construction of...

Problems solved by technology

[0003] There are certain improvements in the use of traditional steel structures. The conclusion is as follows: First, traditional steel structures mostly use prefabricated structures. Different types of steel structure components, these prefabricated components include horizontal foundation construction, vertical foundation construction, oblique additional parts, horizontal additional parts, vertical additional parts and assembly connection parts, etc., are constructed according to specific construction requirements during the prefabrication process Make different lengths and widths and parts. These different types and specifications need to be positioned according to the needs of the construction. Therefore, once they are produced, they can only be applied to the specific requirements of the construction needs. When the steel structure building needs to be demolished, These parts become waste and need to be recycled and processed, resulting in a waste of resources and cannot be used for turnover; secondly, many positions of traditional steel structures are connected by welding when they are in use. Although this connection method improves The stability of the connection, but the overall structure has insufficient strain elasticity, insufficient strain resistance, and weak prestress. There are certain risks, especially for large-span operations, and the risk is higher. Some steel structures are connected by bolts, but there are too many bolt connections. , resulting in a complex overall connection structure, too many connection points, and cumbersome operations, which is another defect of the existing steel structure connection; thirdly, the traditional steel structure needs to have a certain span and height, and the prefabricated structure is used for construction during construction. When working, they often rely on their own design structure to implement horizontal and vertical construction operations. The construction steps and methods are fixed, and they do not have the ability to extend. Whether it is vertical or horizontal, construction operations must be carried out according to the length and height of the construction. With the requirement of large-span and super-height operation extension, in some steel structure construction operations with specific requirements, this traditional inherent prefabricated construction mode loses its superiority, especially in some constructions that need to gradually increase the span and height of steel structures During the operation, the traditional steel structure itself has great disadvantages in its structural design and construction methods
