Problems solved by technology
[0004] 1. Due to the perennial dynamic load, it is easy to cause the inner structure to directly bear the impact, and it is prone to local buckling, which eventually leads to the destruction of the steel tube concrete structure;
[0005] 2. When protecting against coupled disasters such as fire, impact, and address disasters, the protection ability is weak and the protection function is single, which can easily cause the structure to be quickly damaged and unstable, which limits the development and application of steel pipe concrete structures

The invention discloses a concrete-filled steel tube structure with fireproof, anti-collision and shockproof functions and a manufacturing process. The structure comprises a concrete-filled steel tube structure body and a support; the concrete-filled steel tube structure body comprises a steel tube and a first protective sleeve; a concrete layer is poured in an inner cavity of the steel tube; the outer wall of the first protective sleeve is coated with protective paint; an interlayer is filled with a first asbestos board; the support is a high-damping shock insulation rubber support and comprises a support body and a supporting block; the support body is composed of multiple layers of steel plates and rubber; and the concrete-filled steel tube structure body, the supporting block and the support body are combined into a whole through high-cohesiveness epoxy resin mortar. The concrete-filled steel tube structure fills the gap of domestic measures for the fireproof, anti-collision and shockproof energy absorption capacity of a concrete-filled steel tube column structure, provides a more advanced practical protective measure and is suitable for building anti-collision structures of underground parking lots, bridges, elevated piers and other wide and important public places.
Description
technical field [0001] The invention relates to the technical field of steel pipe concrete structures, in particular to a steel pipe concrete structure with fireproof, anti-collision and shockproof functions and a manufacturing process. Background technique [0002] Concrete filled steel pipe refers to a structural member formed by filling concrete in steel pipes, and the steel pipes and their core concrete can bear external loads together. Concrete has high compressive strength but weak bending resistance, while steel, especially section steel, has strong bending resistance and good elastic-plastic properties, but it is prone to instability and loses axial compressive capacity when it is under compression. Concrete-filled steel tubes can combine the advantages of the two in structure and play a role together, thereby greatly improving the bearing capacity. Conventional steel-filled concrete-filled structural members are mainly composed of various columns, beams, slabs or c...
