Abstract
The invention discloses a multi-cavity concrete-filled steel pipe combination column with stiffening ribs and a manufacturing method. The multi-cavity concrete-filled steel pipe combination column is characterized in that two stiffening plates are arranged between two side plates, and sealed steel plates are arranged in opening positions of the two side plates, thereby forming the multi-cavity concrete-filled steel pipe combination column with the stiffening ribs. The multi-cavity concrete-filled steel pipe combination column with the stiffening ribs, disclosed by the invention, has the same width with a wall, protruding of corner angles of indoor columns is avoided, and the using area and the attractiveness of a room can be enlarged; cavities arranged at two sides can be used as edge constraint components of the whole concrete-filled steel pipe column after the cavities are fully filled with concrete, so that the bearing capacity and the energy dissipating capacity of the multi-cavity concrete-filled steel pipe combination column can be increased; a rectangular steel pipe is divided into three small cavities by the stiffening plates, so that the constraint capacity of the steel pipe on concrete is increased; meanwhile, local buckling of the steel plate can be delayed or prevented, and the bearing capacity and the ductility of the components are increased.

Chamber concrete filled steel tube coupled column and manufacture method.
Background technology
Along with economic globalization, the raising of the level of urbanization, urban population closeness is gradually increased so that a large amount of high levels are not
Break and emerge in large numbers.This just high-rise in the urgent need to new technical support and design of tier building and construction.
Concrete filled steel tube utilizes steel pipe and the interaction in loading process of the concrete bi-material, and i.e. steel pipe is to coagulation
The effect of contraction of soil makes concrete be in complex stress condition, so that the intensity of concrete is improved, plasticity and toughness are big
For improving.Meanwhile, after steel duct fill concrete, due to the supporting role of concrete, can avoid or delay steel pipe walls
Flexing.The combination of bi-material compensate for respective shortcoming so that material property gives full play to.
Along with development and the growth in the living standard of society, people are to the usable floor area of house and cosmetic requirements increasingly
High.Traditional circle or Concrete Filled Square Steel Tubes post, be generally not capable of being surrounded by body of wall completely, and suspension column is the most prominent
House interior, takies certain interior space so that furnishings and room are arranged by a definite limitation.Use square-section steel
Pipe concrete coupled column, can accomplish with wall with wide, solve the problem that post highlights corner angle.
Research shows, the concrete-filled rectangular steel tube coupled column of general type, and the constraint of core concrete is only limitted to by steel pipe
Angle point, more weak at periphery, bearing capacity is relatively low.Band ribbed stiffener multi-cavity steel tube concrete coupled column horizontally set drawknot of putting more energy into is arranged
Execute, shaft is divided into some chambers, make steel plate that the effect of contraction of concrete to be strengthened, reduce the flakiness ratio of steel plate simultaneously, anti-
Stop or delay the cripling of steel plate.It can improve as the edge constraint component of concrete filled steel tube coupled column in two side cavity
Bearing capacity and energy dissipation capacity.
Summary of the invention
It is an object of the invention to overcome above-mentioned deficiency, it is provided that a kind of band ribbed stiffener multi-cavity steel tube concrete coupled column and system
Make method, solve conventional post indoor and highlight the problem of corner angle, improve bearing capacity and the ductility of Multicarity concrete filled steel tube coupled column.
In order to achieve the above object, a kind of band ribbed stiffener multi-cavity steel tube concrete coupled column, it be arranged in parallel including two pieces
Side plate, two pieces of side sheet rooms are provided with two stiffeners, are provided with sealing steel plate at the both-side opening of two blocks of side plates, sealing steel plate with
Two stiffeners and two side plate three cavitys of composition, be all perfused with concrete in three cavitys.
Described sealing steel plate, stiffener and side plate all use same intensity grade steel.
Described side plate strength grade is than sealing steel plate and the low grade of strength grade of stiffener.Described sealing steel plate and adding
The thickness of strength plate is 8-16mm, and the thickness of side plate is 6-10mm.
Described concrete is normal concrete or high-strength concrete.
The distance of said two stiffener distance side plate openings respectively is equal.
The manufacture method of a kind of band ribbed stiffener multi-cavity steel tube concrete coupled column, comprises the following steps:
Two stiffeners are welded between two side plates by step one；
Step 2, at the opening part solder up steel plate of two side plate both sides, forms three cavitys；
Step 3, concrete perfusion in three cavitys, it is band ribbed stiffener multi-cavity steel tube concrete coupled column after molding.
In described step one, first two stiffeners are welded on a side plate, form " ∏ " type cross section, then by " ∏ "
Type cross section and another plate-side plate welding.
Said two stiffener is welded on the equidistant side plate of distance side plate openings respectively.
In described step 3, after concrete perfusion, carry out periodic maintenance.
Compared with prior art, the present invention arranges two stiffeners at two side sheet rooms, and at the opening part of two side plates
Arranging sealing steel plate, thus form band ribbed stiffener multi-cavity steel tube concrete coupled column, the present invention and wall are with wide, it is to avoid indoor-bollard is dashed forward
Go out corner angle, it is possible to increase room usable floor area and aesthetic property, as whole steel core concrete column after two side cavity's concrete filleds
Edge constraint component, can improve its bearing capacity and energy dissipation capacity, and square steel pipe is divided into three little chambers by stiffener, improves steel
The pipe restriction ability to concrete, can delay or prevent the cripling of steel plate simultaneously, improve bearing capacity and the ductility of component.
