Multi-cavity FRP pipe concrete combination column and preparing method thereof

摘要: The invention discloses a multi-cavity FRP pipe concrete combination column. column comprises body and core, an inner cavity ofthe is filled with the core; composed of outer pipe, formed by attaching walls at least two core pipes. further preparing method pipes are attached to form combined section, wall stability body, flexural rigidity transverse protrusions restraint effect can be improved, directly poured into column, transversely expands under action axial load, limited side in three-direction compressed stress state, compressive strength brittleness also improved; construction difficulty greatly reduced, speed increased, building waste furtherbe site more tidy.
