Description
Technical field
The present invention relates to a kind of assembled steel reinforced concrete short columns, available in assembled arthitecutral structure.
Background technology
Combined steel and concrete column be by shaped steel as inside concrete, and appropriately configured regular reinforcement formed a kind of steel-
Mixed combining structure column.Compared with conventional steel bar concrete structure, steel reinforced concrete high capacity, completion time of project be short, construction cost
It is low, remarkable in economical benefits is current high-rise and high-rise building used by one of primary structure form.
At present, China is just wideling popularize the development of assembled architecture, using assembled method of construction, can reduce construction to week
The destruction in collarette border reduces interference to periphery traffic, saves building time, is conducive to that engineering structure is extensive, standardization
Production, is conducive to construction quality management and control.The fabricated construction of Current Domestic application is chiefly used in multilayer or small high-rise precast frame
Building, using still less in high-rise, high-rise building.And the research spininess of current fabricated construction is to armored concrete knot
Structure, it is less to the assembling implementation of steel-mixed combining structure, more without forming ripe technical specification.Steel reinforced concrete is made
One of primary structure form used by for high-rise and high-rise building realizes that its assembling is built with being beneficial to assembled construction side
Formula is promoted to high-rise and high-rise building, is conducive to research and develop high-performance assembled combining structure.
The content of the invention
The present invention proposes a kind of assembled steel reinforced concrete short columns, while segment splicing mechanical property is ensured, carries
The efficiency of assembling and construction workability of high cylinder.
The technical solution adopted by the present invention is：
A kind of assembled steel reinforced concrete short columns, frame column are formed including multiple Precast Concrete Segmental Bridges；In prefabricated subsection
Equipped with reinforcing bar, end is equipped with level-one end face and two level end face；Reinforcing bar is arranged on the outside of level-one end face；Level-one end face is arranged in two level
On the outside of end face；Longitudinal reinforcement is disposed on the outside of reinforcing bar, multiple stirrups are equipped on the outside of longitudinal reinforcement；Longitudinal reinforcement end is arranged in two
On the outside of grade end face.Reinforcing bar outside weldings have nodes domains beam connecting component.
A kind of assembled steel reinforced concrete short columns, Precast Concrete Segmental Bridges temporary support structure；Including：Support link, ring
Beam, segment anchor block；Support link is fastenedly connected by upper lower nut with ring beam；Ring beam is bolted to segment anchor block；Section
Section anchor block is fixedly connected by anchor bolt with prefabricated subsection.
It is an advantage of the invention that：
1st, the present invention to be to be starting point division cylinder segment at adjacent floor height half, segment stitching position internal force compared with
It is small, reasonable stress；And avoid the discontinuous of nodes domains, it is easier to realize the design principle of the weak component of strong node of structure.
2nd, the present invention is by setting temporary support system fitted bolt micro-tensioning system, realizes cylinder segment in place and precision
The high efficiency of adjusting.The intensity of temporary support system, rigidity and stablize the requirement that sexual satisfaction multi-segmental is constructed simultaneously, it can be further
Improve overall structure speed of application.
3rd, cylinder segment of the present invention link field avoids reinforcing bar and bar connecting position by the way of postposition longitudinal reinforcement
In same position, cylinder is also easy to produce weak link, while avoids the construction stage and indulge stop of the muscle to reinforcing bar splicing operation face,
More operating spaces are provided for reinforcing bar splicing, beneficial to construction workability.
4th, the present invention is reusable for segment to be aided in install, and intensity, rigidity stablize sexual satisfaction multi-segmental simultaneously
Assemble the requirement of construction.

Specific embodiment
Assembled combined steel and concrete column assembly process is further described referring to the drawings 1-5.
A kind of assembled steel reinforced concrete short columns, frame column are formed including multiple Precast Concrete Segmental Bridges；
Reinforcing bar 1 is equipped in prefabricated subsection, end is equipped with level-one end face A and two level end face B；
Reinforcing bar 1 is arranged on the outside of the A of level-one end face；Level-one end face A is arranged on the outside of the B of two level end face；
1 outside of reinforcing bar is disposed with longitudinal reinforcement 4, and 4 outside of longitudinal reinforcement is equipped with multiple stirrups 2；4 end of longitudinal reinforcement is arranged
On the outside of the B of two level end face.
1 outside weldings of reinforcing bar have nodes domains beam connecting component 3.
A kind of assembled steel reinforced concrete short columns, Precast Concrete Segmental Bridges temporary support structure；
Including：Support link 6, ring beam 7, segment anchor block 8；
Support link 6 is fastenedly connected by upper and lower adjusting nut and ring beam 7；

Embodiment
1. prefabricated subsection form；
The prefabricated subsection column can be there are many section form, such as circular, rectangle and other odd-shaped cross sections, can be single
One section may also be variable cross-section；By taking the segment of rectangular section as an example, segment form such as Fig. 1, in figure, reinforcing bar protrudes from level-one end face A,
Longitudinal reinforcement end protrudes from two level end face B.
2. Precast Concrete Segmental Bridges；
1) temporary support structure is installed：First anchor block is fixed on and has completed segment, ring beam and support link are installed afterwards, and
Another ring beam is fixed in the other end of connecting rod.Anchor block is installed on cylinder segment to be installed.
2) cylinder segment to be installed is in place：The cylinder segment of anchor block has been installed in lifting, will to be positioned over connecting rod another for anchor block thereon
One end ring beam, by adjusting the relative position between ring beam and four anchor blocks come the water that adjusts segment to be installed Yu installed segment
Flat relative position segment to be installed and has installed the longitudinally opposed position in segment by adjusting interlinking lever end bolt to adjust.
3) reinforcing bar, bar connecting between segment：Splice two segment reinforcing bar by the way of welding or bolt, afterwards using overlap joint
The mode of welding or sleeve connection disposes link field longitudinal reinforcement, arranges link field stirrup.
4) link field concrete is poured：Concrete blinding is disposed, by template upper end preformed hole concrete perfusion, and is carried out
Concrete vibrating blocks preformed hole, concrete curing shaping.
Above-mentioned segment design avoids column intensity, rigidity and occurs at section assembling compared with macromutation；Cylinder globality is more
It is good；Temporary support system allows segment fine position, ensure that cylinder construction precision and workability, while temporary support system expires
Requirement in terms of sufficient multi-segmental while the intensity of construction, rigidity, stability can accelerate the speed of application of cylinder.
Protection scope of the present invention includes but not limited to the product and pattern of above-mentioned specific embodiment, any to meet this hair
Appropriate variation that the assembled combined steel and concrete column of bright claims and any those skilled in the art do it or
Modification, should all fall the protection domain in this patent.
