Abstract
The invention discloses a multi-cavity steel pipe concrete composite column with a rectangular steel pipe end column and a method. The end column is a composite column of hot rolled rectangular steel pipes and side plates, and is as wide as a wall to avoid prominent edges and corners of an indoor column, so that the use area and beauty of a room can be increased, the hot rolled rectangular steel pipes are filled with concrete to be used as an edge constraint component for an entire steel pipe concrete column, so as to be capable of improving the bearing capacity and energy dissipation capacity of the steel pipe concrete column, a large chamber formed by each of the side plates and each of the hot rolled rectangular steel pipes is divided into two small chambers through a stiffened plate, so that the confining capability of the steel pipes for the concrete is improved, furthermore, the local buckling of a steel plate can be delayed or prevented to improve the bearing capacity and ductility of the component.
Description
Technical field
The invention belongs to the concrete filled steel tube coupled column field of multilayer structure, being specifically related to a kind of newel post is that rectangular steel pipe is many

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, the i.e. steel pipe constraint to concrete
Effect makes concrete be in complex stress condition, 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.Bi-material
Combination 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.Tradition
Circle or Concrete Filled Square Steel Tubes post, be generally not capable of being surrounded by body of wall completely, suspension column greatly prominent house interior,
Take certain interior space so that furnishings and room are arranged by a definite limitation.Employing concrete filled steel rectangular tubes combines
Post, 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 steel pipe is only limitted to angle point to the constraint of core concrete,
Periphery is more weak, and bearing capacity is relatively low.Newel post be the multi-cavity steel tube concrete coupled column of rectangular steel pipe arrange at edge confining part with
Improving its bearing capacity and energy dissipation capacity, horizontally set is put more energy into box construct, shaft is divided into some chambers, makes steel plate to concrete
Effect of contraction strengthen, reduce the flakiness ratio of steel plate simultaneously, prevent or delay the cripling of steel plate.
Summary of the invention
It is an object of the invention to overcome above-mentioned deficiency, it is provided that a kind of newel post is multi-cavity steel tube concrete coupled column and the side of rectangular steel pipe
Method, 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, delays
Or avoid stiffness of structural member bearing capacity and the reduction of ductility caused due to steel pipe wallboard cripling, give full play to the performance of material.
In order to achieve the above object, a kind of newel post is the multi-cavity steel tube concrete coupled column of rectangular steel pipe, including two pieces be arranged in parallel
Side plate, two pieces of side sheet rooms are vertically installed with stiffener composition " work " font, and the opening part of two pieces of side plate both sides is all welded with hot rolling square
Shape steel pipe, makes two hot rolling rectangular steel pipes and two blocks of side plates and stiffener two inner chambers of composition, two inner chambers and two hot rolling rectangles
Steel pipe is all filled with concrete.
The steel using identical strength classes of structural steel of described hot rolling rectangular steel pipe, side plate and stiffener.
A strength classes of structural steel grade lower than the strength classes of structural steel of hot rolling rectangular steel pipe of described side plate and stiffener.
The thickness that thickness is 8-16mm, side plate and stiffener of described hot rolling rectangular steel pipe is 6-10mm.
Described concrete is normal concrete or high-strength concrete.
The length of described two blocks of side plates is equal, and stiffener is vertically fixed on the centrage of two blocks of side plates.
A kind of newel post is the manufacture method of the multi-cavity steel tube concrete coupled column of rectangular steel pipe, comprises the following steps:
Step one, is vertically welded in stiffener on two side plates, forms " work " font cross section；
The both sides of the edge of two hot rolling rectangular steel pipes with " work " font cross section are welded by step 2 respectively, form two inner chambers；
Step 3, concrete perfusion in two inner chambers and two hot rolling rectangular steel pipes, becoming newel post after molding is rectangular steel pipe
Multi-cavity steel tube concrete coupled column.
In described step one, stiffener is vertically welded on the centrage of two blocks of side plates.
In described step 3, after concrete perfusion, carry out periodic maintenance.
Compared with prior art, the newel post of the present invention is the coupled column of hot rolling rectangular steel pipe and side plate, and with wall with wide, it is to avoid room
Inner prop highlights corner angle, it is possible to increase room usable floor area and aesthetic property, mixes as whole steel pipe in hot rolling rectangular steel pipe after fill concrete
The edge constraint component of solidifying earth pillar, can improve its bearing capacity and energy dissipation capacity, and stiffener is big with what hot rolling rectangular steel pipe was formed by side plate
Chamber is divided into two little chambers, improves the steel pipe restriction ability to concrete, can delay or prevent the cripling of steel plate simultaneously,
Improve bearing capacity and the ductility of component.
