Abstract
The utility model discloses a kind of band ribbed stiffener multi-cavity steel tube concrete coupled column, at two side sheet rooms, two stiffeners are set, and sealing steel plate is set at the opening part of two side plates, thus form band ribbed stiffener multi-cavity steel tube concrete coupled column, this utility model and wall are 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, square steel pipe is divided into three little chambers by stiffener, 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.
Description
Technical field
This utility model belongs to the concrete filled steel tube coupled column field of multilayer structure, is specifically related to a kind of band and puts more energy into
Rib multi-cavity steel tube concrete coupled column.
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.
Utility model content
The purpose of this utility model is to overcome above-mentioned deficiency, it is provided that a kind of band ribbed stiffener multi-cavity steel tube concrete combination
Post, solves conventional post indoor and highlights the problem of corner angle, improves bearing capacity and the ductility of Multicarity concrete filled steel tube coupled column.
In order to achieve the above object, this utility model includes that two blocks of side plates be arrangeding in parallel, two pieces of side sheet rooms are provided with two
Individual stiffener, is provided with sealing steel plate, sealing steel plate and two stiffeners and two side plates at the both-side opening of two blocks of side plates
Form three cavitys, in three cavitys, be all perfused with concrete.
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.
Compared with prior art, this utility model arranges two stiffeners, and opening at two side plates at two side sheet rooms
Arranging sealing steel plate at Kou, thus form band ribbed stiffener multi-cavity steel tube concrete coupled column, this utility model and wall are with wide, it is to avoid
Indoor-bollard highlights corner angle, it is possible to increase room usable floor area and aesthetic property, mixes as whole steel pipe after two side cavity's concrete filleds
The edge constraint component of solidifying earth pillar, can improve its bearing capacity and energy dissipation capacity, and square steel pipe is divided into three little chambers by stiffener,
Improve the steel pipe restriction ability to concrete, the cripling of steel plate can be delayed or prevent simultaneously, improve the carrying of component
Power and ductility.

Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is described further.
Seeing Fig. 1 and Fig. 2, this utility model includes two blocks of side plates be arrangeding in parallel 3, is provided with two between two blocks of side plates 3
Stiffener 2, is provided with sealing steel plate 1, sealing steel plate 1 and two stiffeners 2 and two sides at the both-side opening of two blocks of side plates 3
Plate 3 forms three cavitys, is all perfused with concrete 4 in three cavitys, and the thickness of sealing steel plate 1 and stiffener 2 is 8-16mm,
The thickness of side plate 3 is 6-10mm, and concrete 4 is normal concrete or high-strength concrete, two stiffener 2 distance side plates 3 respectively
The distance of opening is equal.
Preferably, sealing steel plate 1, stiffener 2 and side plate 3 all use same intensity grade steel.
Preferably, described side plate 3 strength grade is than sealing steel plate 1 and the low grade of strength grade of stiffener 2.
See Fig. 3, manufacture method of the present utility model, comprise the following steps:
First two stiffeners 2 are welded on a side plate 3 by step one, form " ∏ " type cross section, then are cut by " ∏ " type
Face is welded with another side plate 3, makes two stiffeners 2 be welded between two side plates 3, two stiffeners 2 be welded on respectively away from
On the equidistant side plate 3 of side plate 3 opening；
Step 2, at the opening part solder up steel plate 1 of two side plate 3 both sides, forms three cavitys；
Step 3, concrete perfusion 4 in three cavitys, carry out periodic maintenance after concrete perfusion 4, after molding, be band
Ribbed stiffener multi-cavity steel tube concrete coupled column.
