Concrete filled steel tube combined special-shaped column may include multiple single limb columns, domestic still to lack each single limb intercolumniation in suspension column region Reliable type of attachment, to guarantee that there is reliable bond-anchorage energy between concrete filled steel tube combined special-shaped column and external wrapping concrete Power.
Concrete filled steel tube skyscraper is more demanding to suspension column stress performance, the concrete combined special-shaped column component of novel steel tube Applied to the reliable foot joint of stress in skyscraper, needing one kind to match therewith.
Summary of the invention
The utility model is to solve technical problem present in well-known technique and provide a kind of reliable steel tube concrete of stress Native combined special-shaped column outer-enwraped type foot joint, the node can satisfy the combined special-shaped column structure system of concrete filled steel tube and be applied to height Suspension column force request in layer building.
The utility model is adopted the technical scheme that solve technical problem present in well-known technique: a kind of steel pipe is mixed Solidifying soil combined special-shaped column outer-enwraped type foot joint, including the reinforced concrete enveloped structure being arranged in around Special-Shaped Column and welding Column root-plate in special-shaped column bottom, the column root-plate is affixed by anchor screw bolt and nut with basis, described anchor bolt preburied in base In plinth, it is cast with plain concrete layer between the column root-plate and basis, is equipped in the reinforced concrete enveloped structure Shearing-resistant member, the shearing-resistant member are fixed in Special-Shaped Column.
The shearing-resistant member includes multiple limb column connection i-steel components, and all limb columns connect i-steel component compartment of terrain It is arranged between coaxial two adjacent Special-Shaped Column list limb columns, the limb column connection i-steel component is horizontally disposed, and the limb The web of column connection i-steel component is vertically arranged.
The shearing-resistant member further includes multiple pegs being evenly arranged on the outside of Special-Shaped Column list limb column.
The arrangement of reinforcement of the reinforced concrete enveloped structure includes vertical muscle and stirrup.
Backing plate is equipped with below the nut.
The utility model has the advantages and positive effects of: using Special-Shaped Column reinforced concrete enveloped structure, steel pipe is mixed Solidifying soil combined special-shaped column and reinforced concrete enveloped structure form the common stress of composite structure, not only increase steel tube concrete local soil type The bearing capacity of Special-Shaped Column is closed, while making concrete filled steel tube combined special-shaped column structure suspension column that there is very strong anti-bending bearing capacity.And And the utility model force transferring structure is reliable, easy for construction, steel construction part is prefabricated in the factory, and construction site need to only carry out positioning peace Dress and concreting.
