Description

A kind of strength core steel core concrete column of interpolation Y shape steel plate
Technical field
The utility model relates to a kind of steel core concrete column, particularly a kind of strength core steel core concrete column of interpolation Y shape steel plate.Belong to fields such as construction work, bridge engineering, be applicable to that requirement for bearing capacity is big, the shaft sectional dimension is subjected to material or function of use to require the steel core concrete column engineering that can't increase.
Background technology
Steel core concrete column refers to that in steel pipe fill concrete makes the structural element of steel pipe and the common bearing load effect of core concrete thereof, is widely used in the construction works such as factory building, frame construction.Steel pipe and concrete advantages can be got up on function, can make concrete be in the three dimension stress state, because the cuff effect, compressive strength improves bigger.Owing to concrete existence, improved the rigidity of steel pipe simultaneously, both work in coordination with and play a role, thereby have improved load-carrying properties widely, are embodied in the following aspects:
(1) concrete filled steel tube columns bearing capacity height, ductility are good, and anti-seismic performance is superior, and steel pipe makes concrete be in the three dimension stress state to the concrete effect of contraction in its inside, has improved concrete compressive strength; The concrete of steel duct can prevent steel pipe generation cripling again effectively.Studies show that the bearing capacity of steel core concrete column is higher than corresponding steel pipe column bearing capacity and concrete column bearing capacity sum.Interaction between steel pipe and the concrete makes the concrete destruction of steel duct change plastic failure into by brittle fracture, and the ductile performance of member is obviously improved, and has superior anti-seismic performance.The concrete filled steel tubular member shock resistance is also much better than than reinforced concrete member, and the energy absorption performance of structure is good, and no rigidity degeneration or degradation effect are little, and therefore, the anti-seismic performance of steel core concrete column also is better than steel column.
(2) easy construction, the duration shortens greatly, and during the encased structures construction, steel pipe can be born working load and the construction weight of construction stage as stiff skeleton, and construction is not subjected to the influence of concrete curing time; During the encased structures construction, do not need template, simplified concrete maintaining process simultaneously.
(3) be conducive to the fire-resistant of steel pipe and fire prevention, owing to be filled with concrete in the steel pipe, can absorb a large amount of heat energy, increased the fire resistance period of pillar.
(4) decay resistance is better than steel work, and fluid concrete reduces the exposed area of steel pipe in the steel pipe, is subjected to the ambient atmos corroded area than steel work much less, and anti-corruption and anticorrosion required expense are also saved than steel work.
When possessing above-mentioned advantage, for antidetonation and the higher building of requirement for bearing capacity, present steel core concrete column is not because reinforcing bar is established in general inside, and bearing capacity is difficult to the standard that reaches higher; Function of use for building proposes the situation that the inner space has higher requirements, and the common steel tube concrete column is owing to can't the increasing section size being difficult to satisfy its load bearing requirements; Bonding strength between concrete and the steel pipe also is the key factor that influences the structural entity stress performance in addition, but often this is considered not enough in the actual engineering.
In sum, along with steel core concrete column more and more is used in highrise building, bridge engineering and longspan structure, need invention a kind of bearing capacity height, easy for installation, the strength core steel core concrete column fast of constructing at present badly, to satisfy high-bearing capacity that building improves constantly and function of use to the demand of large space.
Summary of the invention
