Abstract
The invention discloses a multi-cavity concrete filled steel tube combined column with C-type steel and a manufacturing method .C-type steel is arranged on the two sides of a rectangular steel tube, concrete is poured into three cavities, and accordingly the multi-cavity concrete filled steel tube combined column with C-type steel is obtained .The combined column and a wall are identical in width, edges and corners are prevented from protruding out of an indoor column, and use area and attractiveness of the room can be improved .After the cavities on the two sides are filled with concrete, the cavities serve as edge constraint components of the whole concrete filled steel tube column, and bearing force and energy-dissipating capacity of the column can be improved; a column body is divided into three cavities, constraint capacity of the steel tube to concrete is improved, local buckling of a steel plate can be delayed or prevented, and bearing force and ductility of the components are improved.
Description
Technical field
The invention belongs to the concrete filled steel tube coupled column field of multilayer structure, be specifically related to multi-cavity steel tube concrete coupled column and the manufacture method of a kind of band C-type steel.
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 continue to bring out.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, i.e. steel pipe to make concrete be in complex stress condition the effect of contraction of concrete, so that the intensity of concrete is improved, plasticity and toughness greatly improve.Meanwhile, after steel duct fill concrete, due to the supporting role of concrete, can avoid or delay the flexing of steel pipe walls.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 more and more higher to usable floor area and the cosmetic requirements of house.Traditional circle or Concrete Filled Square Steel Tubes post, be generally not capable of being surrounded by body of wall completely, the most prominent house interior of suspension column, takies certain interior space so that furnishings and room are arranged by a definite limitation.Use concrete filled steel rectangular tubes 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, steel pipe is only limitted to angle point to the constraint of core concrete, more weak at periphery, and bearing capacity is relatively low.Multi-cavity steel tube concrete coupled column with C-type steel, its shaft is separated into some chambers, make steel plate that the effect of contraction of concrete to be strengthened, reduce the flakiness ratio of steel plate simultaneously, prevent or delay the cripling of steel plate, its bearing capacity and energy dissipation capacity can improve as the edge constraint component of concrete filled steel tube coupled column in two side cavity.
Summary of the invention
It is an object of the invention to overcome above-mentioned deficiency, it is provided that the multi-cavity steel tube concrete coupled column of a kind of band C-type steel and manufacture 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, the multi-cavity steel tube concrete coupled column of a kind of band C-type steel, including rectangular steel pipe, the both sides of rectangular steel pipe are provided with C-type steel, rectangular steel pipe and two C-type steel and form three cavitys, are all perfused with concrete in three cavitys.
Described rectangular steel pipe and C-type steel all use same intensity grade steel.
A strength grade grade lower than the strength grade of C-type steel of described rectangular steel pipe.
Described C-type steel thickness is 8-16mm, and rectangular steel pipe thickness is 6-10mm
Described concrete is normal concrete or high-strength concrete.
Described C-type steel is arranged on the both sides of rectangular steel pipe minor face.
The manufacture method of the multi-cavity steel tube concrete coupled column of a kind of band C-type steel, comprises the following steps:
Two C-type steel are respectively welded at the both sides of rectangular steel pipe by step one, form three cavitys；
Step 2, concrete perfusion in three cavitys, it is the multi-cavity steel tube concrete coupled column of band C-type steel after molding.
In described step one, two C-type steel are respectively welded at the both sides of rectangular steel pipe minor face.
In described step 2, after concrete perfusion, carry out periodic maintenance.
Compared with prior art, the present invention arranges C-type steel in the both sides of rectangular steel pipe, and in three cavitys concrete perfusion, thus obtain the multi-cavity steel tube concrete coupled column of band C-type steel, and with wall with wide, indoor-bollard is avoided to highlight corner angle, room usable floor area and aesthetic property can be increased, as the edge constraint component of whole steel core concrete column after two side cavity's concrete filleds, its bearing capacity and energy dissipation capacity can be improved, shaft is separated into three little chambers, improve the steel pipe restriction ability to concrete, the cripling of steel plate can be delayed or prevent simultaneously, improve bearing capacity and the ductility of component.
