Description
Technical field
The present invention relates to architectural engineering construction technique field, between a kind of conversion layer for high-rise building
Bi-directional symmetrical tilts the installation method of steel column.
Background technology
In skyscraper particularly in high-rise building, functional requirement becomes increasingly complex.Under ground portion and ground are some
Layer function is typically designed as parking lot and shopping centre, and these regions need huge pillar net layout；Floor more than shopping centre is mainly made
For office building, hotel guest room etc., the space required for the region of this function type is less, if also built using huge pillar web form
Build space cannot be utilized well, be in this case just relatively suitable for using pillar net layout.Generally colum network size
The storey setting changing is structural transition layer.The inclined in two-way component that V-shaped steel column etc. is similar to is commonly used in structural transition layer
It is used as the main bearing member of conversion layer, the more aobvious dynamics of elevation of building can be made, enhance the sense of stability of building again.
Traditional working measure is that setting bracing frame to guarantee that dip member (tilting steel column) is steady below dip member
Fixed, but there are following problems in traditional construction method:
1st, the method that bracing frame adopts vertical supporting, dip member, while producing vertical pressure to bracing frame, also can
Bracing frame is produced with horizontal thrust, impact is using safety it is therefore desirable to take steps to the impact of elimination of level thrust.
2nd, bracing frame needs to be placed on bottom girder steel or beams of concrete, when girder steel is fitted without or beams of concrete does not possess
During stress condition, just cannot lay bracing frame, dip member just cannot be installed.
3rd, when bracing frame is arranged on substructure, the work surface construction of impact bottom.
4th, when adjustment tilts steel column angle of inclination, bracing frame can produce larger pressure on substructure, works as bottom
In addition it is also necessary to reinforce when structural bearing capacity is limited.
5th, bracing frame length can not be adjusted flexibly, need to extend by welding or gas cutting cut short.
6th, when the height of conversion layer is higher, the height of bracing frame also must be high, and this has resulted in the usage amount of bracing frame
Larger, and in engineering construction each component be required for support, connecting elements between components before being fitted without it is impossible to
It is used in turn, the consumption of bracing frame support body material certainly will be increased.
7th, dip member is connected by horizontal member, therefore more sensitive to the precision of level interval, and bracing frame
It is vertically arranged, adjustment component very little in the horizontal direction, can increase the absolute altitude of steel column during adjustment, simultaneously can be to tilting steel
Between post and conversion layer bottom connecting node steel column, the connection otic placode of docking location and bolt produce larger pulling force, and this makes use of momentum
Necessarily the weld seam between otic placode and otic placode and steel column is carried out lengthening thickening, bolt is also required to accordingly increase, to practice of construction
For waste time and energy.
Content of the invention
The technical problem to be solved in the present invention is to provide the bi-directional symmetrical between a kind of conversion layer for high-rise building to incline
The tiltedly installation method of steel column.By method provided by the present invention, bi-directional symmetrical tilts steel column when mounted, completely left out frame
If the working procedure of bracing frame, in work progress, directly two neighboring inclination steel column is connected by connecting rod, and then make
In the case of tilting steel column adjustment equal angular, more simple to operate than being adjusted with bracing frame with connecting rod adjustment, tilting
The internal force producing between steel column and conversion layer bottom connecting node steel column is little, and there is not inclination steel column when being adjusted with bracing frame

The connecting rod discord other structures being adopted contact, and are not affected by other structures construction speed, bearing capacity, also will not be right
Other operations impact, and also make bi-directional symmetrical inclination steel column be provided with secondary adjustment two inclination steel column cylinders when mounted
Between distance function.
Description orientation employed in herein word " on ", D score, "left", "right" etc. be for explanation facilitate base
For the orientation shown in drawing in the accompanying drawing, in actual device these orientation because of device disposing way and
Different.
In sum, embodiment of the present invention only provides a kind of optimal embodiment, in the technology of the present invention
Hold and technical characterstic has revealed that as above, but one skilled in the art scholar is still potentially based on disclosed content and makees
The various replacements without departing substantially from creation spirit of the present invention and modification；Therefore, protection scope of the present invention is not limited to disclosed in embodiment
Technology contents, therefore equivalence changes that all shapes under this invention, construction and principle are done, be encompassed by the protection model of the present invention
In enclosing.
