Description

The two concrete combined special-shaped post of plate joint steel pipe of assembling

Technical field

The present invention relates to a kind of for the hetermorphiscal column in building structure, particularly relate to the two concrete combined special-shaped post of plate joint steel pipe of a kind of assembling.

Background technology

The component that steel core concrete column refers to fill concrete in steel pipe and formed, it takes full advantage of the interaction of material in loading process that steel pipe and concrete two kinds of mechanical properties differ greatly, make up bi-material shortcoming separately, the advantage of both performances, concrete core cylinder anti-side rigidity is large, effectively resists geological process.Steel pipe and the common bearing load of core concrete, simultaneously steel pipe provides effect of contraction for core concrete.

Steel pipe concrete profiled pile is owing to having the excellent mechanical performances of combining structure, under the prerequisite meeting structural bearing capacity and rigidity requirement, can accomplish that interior wall does not go out rib, meet building using function preferably, become the important feature system of engineer applied, it is high that steel pipe concrete profiled pile structure solves daylighting, ventilate, building structure inner space utilization rate is high, economize on resources, the requirement of the building such as flexible layout using function, there are many advantages, the advantage of hetermorphiscal column combined with steel reinforced concrete special-shaped column structure and encased structures, there is bearing capacity high, toughness and plasticity strong, anti-seismic performance is good, stability is good, fire resistance is good, antiseptic property is superior, duration is short, the feature such as to construct simple, hetermorphiscal column has catered to the requirement of innovation dwelling house system, unique advantage is occupied in housing construction market, become the developing direction that of Structural Engineering Subject is important.

At present, the concrete combined special-shaped post of the concrete combined special-shaped post of steel plate joint steel pipe many employings veneer joint steel pipe, bearing capacity is not high, cannot be applied in high level, so just constrain the development of concrete filled steel tube combined special-shaped column, its application is restricted.

To sum up, research and develop a kind of supporting capacity high, can be applied in highrise building, the pillar pole simultaneously with good ductility and anti-seismic performance is necessary.

Summary of the invention

The present invention provides a kind of assembling two concrete combined special-shaped post of plate joint steel pipe for solving problems of the prior art, and this hetermorphiscal column supporting capacity is high, can be applied in highrise building, has good ductility and anti-seismic performance simultaneously.

The technical scheme that the present invention takes for the technical problem existed in solution known technology is: the two concrete combined special-shaped post of plate joint steel pipe of a kind of assembling, comprise an intermediate rectangular steel pipe and at least two peripheral rectangular steel pipes, described intermediate rectangular steel pipe is connected by the two piece junction steel plates contour with it with described peripheral rectangular steel pipe, described junction steel plate vertical is arranged, and with the lateral vertical of described intermediate rectangular steel pipe and described peripheral rectangular steel pipe, the horizontal floor that multiple tracks is evenly arranged is provided with in the outside of described junction steel plate, described horizontal floor welds with the described intermediate rectangular steel pipe and described peripheral rectangular steel pipe being positioned at its two ends, in described intermediate rectangular steel pipe and described peripheral rectangular steel pipe, build concrete structure I respectively, in described intermediate rectangular steel pipe, described peripheral rectangular steel pipe and relative two pieces of spaces that described junction steel plate surrounds, build concrete structure II, the cross section comprising the block construction of the described intermediate rectangular steel pipe described peripheral rectangular steel pipe adjacent with two is L-shaped.

Described peripheral rectangular steel pipe has two, and the cross section of described hetermorphiscal column is L-shaped.

Described peripheral rectangular steel pipe has three, and the cross section of described hetermorphiscal column is T-shaped.

Described peripheral rectangular steel pipe has four, and the cross section of described hetermorphiscal column is cross.

The advantage that the present invention has and good effect are:

One) on structure stress, there is the excellent mechanical performances of combining structure, simple structure, power transmission is clear and definite, and bearing capacity improves greatly, the combined special-shaped columns bearing capacity of concrete filled steel tube connected for veneer is not high, cannot be applied to the problem in highrise building, in the concrete combined special-shaped post of two plate joint steel pipes, steel pipe and concrete pressure zone area increase, and the overall performance of pillar obtains reinforcement, bearing power increase is remarkable, may be used in high-rise steel structure house and public steel building.

Two) under the prerequisite meeting structural bearing capacity and rigidity requirement, can accomplish that interior wall does not go out rib, layout is comparatively flexible, can meet building using function preferably, be particularly suitable for the requirement of steel structure of housing to space.Become the important feature system of engineer applied, solve daylighting high, ventilate, the building using function requirement such as building structure inner space utilization rate is high, economize on resources, flexible layout.

Three) compared with pure steel structure, can steel be saved, reduce costs, and cripling is less likely to occur, and there is good fire resistance, good anti-seismic performance, stability is good, antiseptic property is superior.

Four) factory-made component, Site Welding, improves speed of application, shortens the duration.
