Further, by vibrational power flow of the present utility model, substantially increase construction efficiency, ensure that workmanship; Not only eliminate ater-casting concrete localized seepage phenomenon, and eliminate because of behind indwelling ater-casting to the adverse effect of basement construction period; Be applicable to the cleaning of industry and civilian construction basement wall board post poured band.
Further, ater-casting does not stay Temperature Joint as super long building and do not stay the technical measures of settlement joint between highrise building high-level partial and podium.Seam because of ater-casting is wide closely related with the thickness of wall, plate, water after design the seam of band wide time should do following consideration, 200mm is less than to wallboard thickness, stitches and widely get 800mm; Be greater than 200mm, stitch wide getting and be no more than 1000mm, to the base plate of basement, stitch and widely generally get 1000mm, when base plate thickness is more than 1000mm, when being less than 1500mm, stitching and widely get 1000mm, when base plate thickness is greater than 1500mm, stitches and widely get 1200mm.
To the form of fracture of ater-casting seam crossing, should process according to wallboard thickness concrete condition.General wallboard thickness being less than to 300mm, can make vertical masonry joint; Thickness is greater than to the wallboard of 300 mm (but being no more than 600mm), stairstepping or upper and lower symmetrical groove shape can be made, thickness is greater than to the wallboard of 600mm, the form of concavity or polygon spill can be done.
Reinforcing bar process in ater-casting, whether through reinforcing bar disconnect, and is the type of ater-casting (seam).For pouring after settlement, reinforcing bar should be through, waters band to shrinkage joint, and reinforcing bar should disconnect, and to beam and slab structure, plate breaking of muscle and tendon is opened, and beam muscle should be through.If reinforcing bar does not disconnect, the concrete shrinkage near reinforcing bar will suffer restraints, and plate breaking of muscle and tendon is opened, beam muscle should be through, if reinforcing bar does not disconnect, the concrete shrinkage near reinforcing bar will suffer restraints, appear at the crack beyond predetermined portion after producing tensile stress, thus reduce the ability of structure tension carrying.
Allow section percentage according to the joint of specification to reinforcing bar, arrange ater-casting should on two or more section, and the ater-casting on different section should tortuously be communicated with.Meanwhile, ater-casting should be arranged on the less position of structural internal force.
The concrete construction requirement in ater-casting: the rear pouring concrete in ater-casting, should use non-shrinkage concrete to fill with real.Non-shrinkage concrete can adopt expansive cement mixing, and admixture also can be adopted to have the ordinary Portland cement mixing of the Admixture of expansion, and concrete strength is at least identical with first pouring concrete or improve one-level.
The watering time of the rear pouring concrete in ater-casting, selects different watering times by dissimilar ater-casting.Post-concreted expansion strip---determine according to contraction deadline of first placing of concrete.Different cement type, Different Water-Cement Ratio, the concrete of different temperature condition maintenances will be distinguished its time of having shunk and determine, and after being generally casting and constructing, 60d carries out ater-casting concrete casting, in construction period urgent and have special at need, also should not be less than 30d.Indwelling pouring after settlement, generally after building settlement is stable, then should pour into a mould the concrete of ater-casting.
The joint form of ater-casting, strictly must press working drawing construction.Bulkhead or fill raised line according to interface shape on bulkhead during constuction joint construction.The cleaning of the concrete surface that will harden before fluid concrete, dabbing, moistening, must vibration compacting to the concrete at this place, combine closely to make concrete and hardened concrete.Especially basement bottom board more will be noted improving its impermeable structure ability, avoids the phenomenon that seeps water.
After the first pouring concrete of ater-casting completes, should manage to protect, adopt top cover, surrounding temporary railing or go along with sb. to guard him masonry and the method such as to go along with sb. to guard him.Prevent sanitary fill in ater-casting be difficult to cleaning and work progress in reinforcing bar contaminated, trample.
Water part concrete behind ater-casting and must use non-shrinkage concrete, with good conditionsily preferably mix some early strength water-reducing agents, should do examination and join before construction, mixing wants conscientious, meticulously pours dense, is also noted that maintenance afterwards.
Ater-casting is across interior beam slab before rear pouring concrete is not yet poured into a mould, and structure on two sides is in cantilever force state for a long time.In construction period, this can not be removed across interior template and support, after rear pouring concrete design strength reaches 75 % of its intensity level, then must remove by basipetal order.After the pouring concrete of ater-casting, determine that the time interval monitors, by these data and with the settlement observation record in the time.
Further, when structure segment length is larger, take following technology technology and working measure to reduce temperature and concrete shrinkage to the impact of structure:
(1) reinforcement ratio is improved at the position that top layer, bottom, gable and vertical wall end standard width of a room in an old-style house equitemperature change greatly, in the Bars In Poured Concrete Slab region that temperature, shrinkage stress are larger, rebar spacing should be taken as 150-200mm, and temperature shrinkage reinforcing bar should be arranged on the last arrangement of reinforcement surface of plate, the upper and lower surface of plate all should not be less than 0.1% along the reinforcement ratio of longitudinal and transverse two directions.Temperature shrinkage reinforcing bar can utilize the through layout of original reinforcing bar, also can arrange distributing bar net separately, and overlaps or anchoring in surrounding member by the requirement of tensile reinforcement with original reinforcing bar.
(2) top layer strengthens heat insulation measure, and exterior wall arranges insulation layer.
(3) Construction Later Casting Zone is set every 30 ~ 40m, bandwidth 800 ~ 1000mm.
(4) top arranges the less form of structure of rigidity, or arranges local temperature seam, structure is divided into the structure that length is shorter.
(5) concrete adopting contraction less, reduces cement consumption, and adds suitable Admixture.
(6) in structure design, give larger swelling stress in the place that structure both shrinks stress is larger and compensate, the width of general reinforcing band is 2m, and suitably increasing between band suitably increases horizontal tectonics reinforcing bar 15% ~ 20%.
