Description
Technical field
The utility model relates to Structural Engineering field, is specifically related to a kind of aspect and compares coated steel frame.
Background technology
With the acceleration of China's Development of China's Urbanization, being becoming tight urban land day, urban architecture is just progressively from high level to superelevation
Layer is fast-developing；High-rise, high-rise building has higher shockproof requirements to structure vertical member, meanwhile, for meeting carrying energy
The demand such as power, rigidity, is typically only capable to strengthen the sectional dimension of post and form " fat post ", have impact on building and uses space.Reinforcing bar mixes
Solidifying soil is owing to having higher intensity, rigidity, ductility, and can reduce column section area, save space, therefore extensively should
For high-rise, high-rise building.
But in Practical Project, required by axial compression ratio control and residence space uses and requires to be limited, combined steel and concrete column
Often restricted by size in one direction, the combined steel and concrete column that height-to-breadth ratio is bigger occurs.The arrangement form of reinforcing bar, hoop
The make of muscle is all relatively big on the impact of coated steel frame anti-seismic performance, meanwhile, concentrates and mostly be square bar in current specifications
The make of bone concrete column, the coated steel frame not having pair cross-section length-width ratio bigger specifies.
Based on this, research exploitation devise a kind of aspect and compare coated steel frame.
Content of the invention
The purpose of this utility model is to provide a kind of aspect than coated steel frame, mixed to solve in prior art
Solidifying earth pillar is limited by a direction size, and anti-seismic performance is low, and the stirrup of existing coated steel frame, the layout side of reinforcing bar
The technical problems such as formula causes overall performance difference, and working procedure is complicated.
The utility model is achieved through the following technical solutions:
A kind of aspect is than coated steel frame, including reinforcing bar skeleton and the concrete being wrapped on reinforcing bar skeleton, steel
Bone skeleton includes long narrow cross reinforcing bar, and the periphery both sides of long narrow cross reinforcing bar are provided with that stirrup is vertical with vertical muscle to be formed by connecting
Column frame.
In prior art, the structural form of square concrete column is owing to being used require by axial compression ratio control requirement, residence space
Restriction, cannot meet high level, the shockproof requirements to structure vertical member for the high-rise building.Accordingly, it is considered to arrive concrete
Post is size-constrained in a direction, therefore devises the bigger coated steel frame of a kind of height-to-breadth ratio, sets steel skeleton structure
Be calculated as long narrow cross reinforcing bar, long narrow cross reinforcing bar cross section for being intersected to form by two axial crosses, an axle in longer I shape,
Another axle is in compared with casual labourer's font.This steel skeleton structure improves the overall performance of reinforcing bar and steel reinforced concrete, carries for concrete short column
Supply more preferable plastic deformation ability, improve its anti-seismic performance.
Than reinforcing bar, long narrow cross reinforcing bar is based on than the aspect described in coated steel frame for aspect
Length-width ratio.Based on the impact of its stress of concrete column being applied to skyscraper, the cross section major axis of its long narrow cross reinforcing bar
Length is more than minor axis length, and long axis length is generally higher than 1.5 with the ratio of minor axis length.
In addition, technical solutions of the utility model are installed in the periphery both sides of long narrow cross reinforcing bar, stirrup is vertical with vertical muscle to be connected
The column frame connecing.Column frame for installing rectangle hoop in the reinforcing bar web both sides of long narrow cross reinforcing bar, and stirrup is not required to wear
Cross the reinforcing bar web of long narrow cross-shaped steel bone, the vertical muscle of stirrup and the reinforcing bar web both sides being similarly disposed at long narrow cross reinforcing bar
Colligation, constrains the concrete in concrete short column and the sliding producing between the web of long narrow cross reinforcing bar, improves coagulation
The stress performance of soil short column.
More than use long narrow cross reinforcing bar, column frame is set in the web both sides of long narrow cross reinforcing bar, can improve narrow
The overall performance of elongated reinforced concrete column, and then ensure the anti-seismic performance of combined steel and concrete column.
Further, described long narrow cross reinforcing bar includes that at least four T font reinforcing bar is welded, long narrow cross-shaped steel
The cross section long axis length of bone is set to h, and minor axis length is b, h/b >=1.5, is to carry out long narrow cross concrete structure here
Limiting, its cross-sectional structure is cross, and the length difference of two axles is relatively big, and long axis length, minor axis length difference multiple are extremely
It is 1.5 times less.
The concrete structure of long narrow cross reinforcing bar can be welded for the end of four or more T font reinforcing bar,
Along the longer side in concrete short column cross section, the cross section of long narrow cross reinforcing bar is in longer I shape, along concrete short column cross section
Shorter side, the cross section of long narrow cross reinforcing bar, in compared with casual labourer's font, arranges the major axis of the cross section of long narrow cross reinforcing bar
Length is set to h, and minor axis length is set to b, h/b > 1.5, preferably h/b is 1.5-4.Long narrow each direction of cross reinforcing bar Jun You side
The edge of a wing is positioned at tensile region, and I shape is symmetrical.
Further, described long narrow cross reinforcing bar is welded by four T font reinforcing bars, and four T steel bones are respectively
First T font reinforcing bar, the 2nd T font reinforcing bar, the 3rd T font reinforcing bar, the 4th T font reinforcing bar, a T font reinforcing bar and the 2nd T
The structure of font reinforcing bar is identical and the end of a T font reinforcing bar is 180 ° of welding with the end of the 2nd T font reinforcing bar, the 3rd T
Font reinforcing bar and the 4th T shaped steel bone structure is identical and the end of the 3rd T font reinforcing bar and the end of the 4th T font reinforcing bar in
The connecting portion of 180 ° of welding is the connecting portion of a T font reinforcing bar and the 2nd T font reinforcing bar.A wherein T font reinforcing bar
The length of reinforcing bar web more than the length of reinforcing bar web of the 3rd T font reinforcing bar, the length of the reinforcing bar web of a T font reinforcing bar
Degree is more than the length on the reinforcing bar edge of a wing of a T font reinforcing bar, and the length of the reinforcing bar web of the 3rd T font reinforcing bar is less than the 3rd T
The length on the reinforcing bar edge of a wing of font reinforcing bar.Being specially T font reinforcing bar to be relatively welded two-by-two, the number of concrete T shaped steel can
To implement to need to set according to reality, it is preferred to use four T font reinforcing bars are welded, and the long narrow cross reinforcing bar of formation is stable
Property more preferable, stress is symmetrical.
Further, described stirrup is rectangle hoop, is arranged on the both sides of the reinforcing bar web of long narrow cross reinforcing bar.This reality
Do not need guiding through the reinforcing bar web of long narrow cross reinforcing bar with the stirrup arranging in new technique scheme, only need to be arranged on long narrow cross
The both sides of the reinforcing bar web of shaped steel bone, concrete mounting means can arrange vertical muscle, stirrup and described vertical muscle in reinforcing bar web both sides
Colligation.The wherein selection of stirrup shape, is mainly easy to carry out vertical muscle and stirrup colligation, thus realizes to concrete and long narrow ten
Being tightly fastened of font reinforcing bar.
Further, described vertical muscle is arranged at the reinforcing bar web periphery of long narrow cross reinforcing bar, uses tied silk to tie up with stirrup
Prick and connect.Here the position relationship of vertical muscle and long narrow cross reinforcing bar is fixed, is specifically as follows vertical muscle and is arranged on long narrow
