Description
Technical field
The invention belongs to technical field of buildings, more particularly to a kind of partial precast assembly hollow profile steel concrete hollow column and
Construction method.
Background technology
Steel reinforced concrete structure (is often translated into Steel Reinforced Concrete Structure, abbreviation SRC knots
Structure), it is a kind of structure type in shaped steel Transducers Embedded in Concrete, and equipped with suitable longitudinal reinforcement and stirrup.Configuration is indulged
Needed for reinforcing bar and stirrup mainly construction, the bearing capacity of component relies primarily on steel sections.In steel reinforced concrete structure structure
In the section of part, the configuration of shaped steel can be divided into steel flanged beam and open web type two major classes.As a kind of important new structural systen, it
Have normal concrete structure and the common advantage of steel construction concurrently：Compared with reinforced concrete structure, due to being configured in cross section
Shaped steel, steel reinforced concrete structure have the significant advantages such as bearing capacity is high, anti-seismic performance is good, sectional dimension is small, speed of application is fast；
Compared with steel construction, due to being enclosed with armored concrete outside shaped steel, steel reinforced concrete structure has big rigidity, low cost, steady
Qualitative good, fire prevention, outstanding advantages of anti-corrosion ability is good.Therefore, from stress performance, economic cost, endurance quality and fire resistance
The advantages of generalized analysis of energy etc., steel reinforced concrete structure has both both reinforced concrete structure and steel construction, tool
Significant energy advantage.
Steel reinforced concrete structure is now widely used in the Important buildings such as Super High and longspan structure, such as Chinese honor, Shanghai
The landmark buildings such as Jin Mao Tower, Shenzhen DiWang Building, Shanghai World Financial Center, the locations CCTV Xin Tai, three phase of international trade main building, and
Less using steel reinforced concrete structure in the general skyscraper and tier building having a large capacity and a wide range, it is main the reason is that type
Steel-concrete structure on-site construction processes are various and construction connection is complicated.Just because of this complicated protrusion disadvantage of construction, cause
The popularization and application of steel reinforced concrete structure are greatly restricted, and the comprehensive performance for causing steel reinforced concrete structure excellent cannot fill
Distribution is waved.
Invention content
In order to overcome the disadvantages of the above prior art, the purpose of the present invention is to provide a kind of partial precasts to assemble empty stomach type
Steel concrete open tubular column and construction method, the thought based on prefabrication and assembly construction, the PSRC open tubular columns that the invention belongs to be prefabricated in the factory,
It can install, be attached finally by overhanging girder steel and beam, plate at the construction field (site), be suitable for different project situation demands, have
The characteristics of easy construction, of low cost, function admirable.
To achieve the goals above, the technical solution adopted by the present invention is：
A kind of partial precast assembly hollow profile steel concrete hollow column, including：

Among the encirclement of stirrup 5.
The shaped steel 3 is channel steel.
The shaped steel 3 is inwardly made of two channel steels in edge of a wing acropodium.
The shaped steel 3 stretches out the both ends of prefabricated high performance concrete open tubular column 1 on column length direction.
The steel plate 4 is equally spaced along column length direction on shaped steel 3 by solder design mode, and it is empty to form rectangular ring
Core structure.
The stirrup 5 is welding compound stirrup or continuous helical high-strength stirrup.
The present invention also provides the construction methods that the partial precast assembles steel reinforced concrete open tubular column, and steps are as follows：
1 is arranged in along column length direction on shaped steel 3 in factory, by steel plate 4 by solder design mode, and it is empty to form rectangular ring
Core structure.
2, in factory, the punching block with local crowning are placed in the rectangular ring hollow-core construction that steel plate 4 and shaped steel 3 are formed
Plate pours high performance concrete open tubular column 1, is placed into vertical muscle 2 and stirrup 5, completes pre-erection；
3 at the scene, prefabricated high performance concrete open tubular column 1 of the installation with vertical muscle 2, shaped steel 3, steel plate 4 and stirrup 5；
4 at the scene, and shaped steel 3 and steel plate 4 are passed through open pore steel plate solder design and high-strength bolt connection and coupled column or steel
Column is directly connected to, or is connect with concrete column transition；It is attached with beam by overhanging girder steel.
Compared with prior art, the beneficial effects of the invention are as follows：
1) easy construction.The making of prefabrication and assembly construction hollow profile steel concrete hollow column is completed in factory, prefabricated components are medium-sized
Steel and steel plate form rectangular ring hollow-core construction, eliminate inside formwork step in the construction process, in building site by will be pre-
The shaped steel of part processed and node or steel column are connect by open pore steel plate solder design and high-strength bolt (or to be connected with concrete column transition
Connect), that is, complete PSRC open tubular column construction and installation.Compared with traditional SRC columns, construction and installation eliminate live assembling reinforcement, formwork,
Form removal and temporary support under erection column.Through rationally designing, the construction and installation of PSRC open tubular columns will be equally convenient with steel column
With it is quick, workability will greatly improve.
2) performance enhancement.PSRC open tubular columns produce hoop constraint power to internal shaped steel, and bearing capacity improves, and inner
Steel welds to form rectangular ring hollow-core construction with steel plate, and dead load effectively reduces, and overall performance and anti-seismic performance are improved；
And in practical engineering application, the concrete of restraint beam and floor does not select concrete strength in column, selects different characteristics
Concrete, can effectively lift structure use functional requirement.
3) construction quality is good.Often there is quality and asks since working procedure is more, difficulty of construction is big in traditional SRC columns site operation
Topic, such as in SRC column webs concrete vibrating difference leakiness and reinforcing bar easily misplaces in intensity deficiency and column, construction quality is easily-controllable
System；And PSRC open tubular columns use prefabrication, concreting to vibrate convenient and steam curing can be used, concrete strength has
Ensure that construction quality is easily controllable, especially when using high performance concrete, PSRC open tubular columns are excellent in terms of quality control on construction
Gesture is more obvious.
Generally speaking, using the PSRC open tubular columns of prefabrication and assembly construction technology compared with traditional SRC columns, working procedure is simplified and applies
Work difficulty reduces, and the long-term crucial problem for restricting the popularization and application of tradition SRC columns is effectively solved, and effectively can be promoted and be filled
Distribution waves traditional SRC columns in the significant advantage of stress performance, endurance quality, fire resistance and economic performance etc., can be with
It is widely used in all kinds of armored concrete and steel building, is particularly suitable for heavy load, large span or complexity, irregular
Skyscraper and high-rise building.Therefore, further investigation is carried out to promote it to promote and apply with far-reaching to PSRC open tubular columns
Practical meaning in engineering.
