Description
Technical Field
The utility model relates to a shaped steel connection structure.
Background
The steel structure material selection principle is to ensure the bearing capacity of the bearing structure and prevent brittle failure under certain conditions, and the factors such as the importance of the structure, the load characteristics, the structure form, the stress state, the connection method, the steel thickness, the working environment and the like are comprehensively considered.
The typical considerations for steel structural joints are as follows:
1. the source of the building block: in theory, steel structural members or connecting members have any workability, but in each specific project, the structural members and the connecting members are always restricted by practical conditions. Experienced designers typically choose easy-to-obtain, easy-to-install section steels and design simple and effective joining means and joining members.
2. Limitation of connection means: one of the construction characteristics of the steel structure is that the steel structure is processed in a factory and assembled on site. This is the reason why a large number of nodes are generated differently from the conventional masonry method. The connection between various section steels mainly has three means: riveting, welding and bolting. The early stage of the steel structure building mostly adopts riveting, the construction is simple, but holes need to be dug on the components, the section performance is reduced, concentrated stress is easily generated at the joints, and the riveting is less adopted recently. Welded joints are adopted, the appearance is concise, the load transfer efficiency is continuous, and the construction operation requirement is high.
3. The connecting member has a hierarchy: there is a complex and logical hierarchical relationship between steel structure building structure systems, and at the connection level, the hierarchical relationship is reflected as the difference between the size of the component and the installation sequence. The purpose of the connection is to realize the hierarchy conversion, and is also the key to realize the conversion of force from three dimensions to two dimensions and finally to transmit the force to the one-dimensional component. The complex connection is usually completed by the combination of a three-dimensional connecting component and a plane connecting component.
4. Plane on which the connecting member is located: the two linear structural members always lie in a plane, which is a stress generation plane of the members, and the connecting member is often designed to effectively resist the stress, bending moment or shearing force in the plane, such as the steel pipe and the welding lug of the inhaul cable always lie in the plane formed by the two; in the case of connection of a plurality of elements, the combined planar elements may correspond to the spatial stress situation.
Therefore, the problems of complex connection, large concentrated stress and large construction difficulty of the steel structure in the prior art are always difficult.
The above-mentioned drawbacks, worth improving.
