Description

Exposed inversion reinforcing bar grout sleeve precast concrete column
Technical field
The utility model belongs to technical field of buildings, is related to a kind of exposed inversion reinforcing bar grout sleeve concrete of assembled Earth pillar.
Background technique
Currently, prefabricated concrete structure has become the trend of future architecture development, and country has put into effect assembled Concrete construction application technology regulation, assembled architecture evaluation criterion and related matched national standard atlas, but assembling In formula concrete frame structure, precast concrete column is as most important vertical applied force component, if being vertically not connected firmly appearance Major safety risks easily occur.When prefabricated components are installed, pre-buried reinforcing bar grout sleeve is packed into from top to bottom and is reserved upwards Vertical reinforcement, reinforcing bar can not check that the Grouted density in reinforcing bar grout sleeve is also not easy to check with grout sleeve position, fill It starches work progress and does not have visual, Grouted density poor controllability.
Reinforcing bar grout sleeve involved in the above method is embedded in styletable in precast concrete column production in advance, specific to tie Structure are as follows: with reinforcing bar in column using being threadedly coupled, major part opening is located at same sleeve microcephaly towards column bottom, the diplopore of side setting Side is drawn from the side of column, and lower opening is grout hole, and upper hole is extravasating hole.
Often occur single or multiple sleeve grouting leakiness during prefabricated concrete column site operation, deposits In biggish security risk;Meanwhile if you need to grouting construction quality testing, it is necessary to destructive processing is carried out, and treated knot Structure can not restore.Therefore, in existing situation, when vertical supporting member is used for assembled architecture, broad masses are psychologically difficult To receive, very big resistance is formed in wideling popularize for China for assembled architecture.
In order to avoid the uncompacted security risk of reinforced bar sleeve grouting that precast concrete frame column is vertically connected to form, originally The technical requirements of utility model combination current designs specification, national standard and related atlas, create that a kind of program is controllable, construction Visually, the adjustable assembly concrete frame structure column reinforced bar sleeve grouting interconnection technique in reinforcement location scene.
Summary of the invention
In view of the foregoing deficiencies of prior art, the purpose of this utility model is to provide a kind of exposed inversion reinforcing bars to fill Sleeve precast concrete column is starched, sleeve portion cannot be adjusted, operating process does not have for reinforcing bar insertion for solving in the prior art The problem of visual, grouting quality inconvenience checks.
To achieve the above object, the utility model provides a kind of exposed inversion reinforcing bar grout sleeve precast concrete column, BROAD SUMMARY includes: precast concrete column, half grouting reinforcement sleeve of inversion type single hole, dedicated hoop tuype is adjustable segmented column down payment Belong to the compositions such as template, template connection bolt, cement base material, mixing machine, air compressor, grouting equipment and measuring equipment;
The exposed inversion reinforcing bar grout sleeve precast concrete column, one end setting assembly tenon, the section of tenon are small In column section;Tenon size matches with half grouting reinforcement sleeve of inversion type single hole;The exposed certain length end band of the column other end Threaded reinforcing bar.It is described assembly tenon periphery it is secondary pour after section be not less than precast concrete column section.
Preferably, assembled architecture precast concrete column is exposed falls to plant the reinforced bar sleeve method of falling plant exposed steel bar sleeve grouting side The equipment grout sleeve of method is used using inversion type, specific structure are as follows:
One end of the half grouting reinforcement sleeve of inversion type single hole is tapered portion, and side bottom is equipped with grout hole, sleeve The other end is joint bar mouth, and joint bar mouth is simultaneously observation panel.
Preferably, assembled architecture precast concrete column further includes the adjustable segmented column down payment category template of dedicated hoop tuype, comprising:
The fixed keyhole of metal form, template, bolt, rubber pad composition, specific structure are as follows:
The template is modular construction, is broadly divided into left template and right mould plate, and left-right template junction is equipped with rubber pad, and And use bolt fastening;
The lower part of the left template and right mould plate is vertical exterior sheathing, and top is equipped with domatic grout groove.
Vertical exterior sheathing and domatic grout groove are integrally formed.
The direction of the vertical exterior sheathing is parallel with the centroidal line of column section.
There are spacing, its spacing 0.5- between the height of the vertical exterior sheathing and the bottom surface of precast concrete upper strata post 1.5cm。
The angle of the domatic grout groove and vertical exterior sheathing is in 30-50 degree.
The height of the domatic grout groove is higher than the bottom surface 2-3cm of precast concrete upper strata post.
The left template and right mould plate are equipped with template keyhole.
As described above, the utility model has the following beneficial effects:
Good effect using the utility model is to can achieve the pre- of assembly concrete frame structure using this technology In vertical connection, the relative position of reinforcing bar and half grouting reinforcement sleeve may be adjusted to closer to concentric, reinforcing bar set column processed Cylinder grouting procedure is visual, controllable, and grouting material does not waste when perfusion, and grouting quality is ensured, to accomplish assembly concrete Frame structure it is highly-safe in cast-in-place concrete frame structure.Precast concrete column used in invention, which is removed, will carry out reinforcing bar Outside being accurately positioned, also the stirrup of connecting portion is reserved, aggregate exposure processing is carried out to concrete joint face.Inversion type Half grouting reinforcement sleeve of single hole is different from the pre-buried mode of traditional prefabricated concrete structure, using upper layer precast concrete column It carries out tightening by hand before lifting and vertical and horizontal direction three-dimensional correction can be direct after precast concrete column lifting in upper layer is in place By in the vertical reinforcement insertion reinforcing bar grout sleeve at upper layer precast concrete column bottom, the level and vertical elevation of upper strata post are adjusted, Then it is fixed temporarily using bearing diagonal, pours into strength cement-based grouting material one by one in reinforcing bar grout sleeve, until completing.Inversion type list It the features such as half grouting reinforcement sleeve material of mouth meets easy to process, purchase and storage, occupies little space, can be with outside precast concrete The embedded half exposed requirement of wallboard half, and can achieve the wallboard requirement adaptable with main structure deformation, to avoid structure Destruction of the part under geological process improves quake-resistant safety performance, can also reduce caused by protruding from inner wall surface because of wallboard support Inner wall surface finishing occupies the effect of larger building use space.
Good effect using the utility model is done for prefabricated assembled concrete frame column bottom connection back-grouting Modular template there is in template visuality when grouting, have when practical with prefabricated assembled concrete column convenient for fixing There is stronger specific aim, the number of turnover of template can also be improved.
