Specific embodiment
As described below is only the preferred embodiment of the present invention, and protection scope is not limited merely to the embodiment, all to belong to
Protection scope of the present invention should belong in technical solution under thinking of the present invention.Simultaneously it should be pointed out that for the art
For those of ordinary skill, several improvements and modifications without departing from the principles of the present invention, these improvements and modifications are also answered
It is considered as protection scope of the present invention.
A kind of precast concrete pours vibrating method, comprising the following steps:
A: concrete stirring, the plurality of raw materials for making concrete is added in blender, starting blender to plurality of raw materials into
Row stirring, stirs into concrete for raw material.
Concrete stir the step of include:
A1: coarse aggregate, cement, fine aggregate are added sequentially in blender, open blender, and aggregate and cement mixing is equal
It is even.Coarse aggregate uses stone, and fine aggregate uses fine sand.The total time that all raw materials are added is no more than 2 minutes.
A2: slowly water is added into blender, be persistently stirred, the addition time of water is maintained at 20 minutes or so.
After water all adds, continues stirring 3 minutes, raw material is stirred evenly.
A3: the stirring thing in blender is poured on working plate, and stirring in 3 minutes or so, system are manually carried out to stirring thing
Obtain concrete.
Concrete obtained can use sub-fraction and laboratory gone to be detected, and another part carries out the production of prefabricated board.
B: concreting,
External mold: being mounted in die station by b1 by fixation kit, and the mixed mud being stirred is poured into external mold, forms concrete bottom
Plate.
B2: installing lower template on concrete floor, offers several first jacks on the side wall of lower template, and several first
It is inserted with reinforcing bar in jack, by the concrete being stirred out of, upside is added to that lower template surrounds frame, forms concrete lower die.
When making concrete lower die, the built-in fitting for needing to be put into concrete can be put into lower template, such as
Electrical appliance kit, the object of pipeline etc.When in concreting to lower template, built-in fitting can be fully wrapped around by concrete, when mixed
When solidifying soil solidification, built-in fitting is secured to the inside of precast concrete.
B3: the template in the installation of the upside of lower template is equipped with the first sealing strip between middle template and lower template, middle template
If being inserted with dry plug Short Item on side wall, the concrete being stirred is added into middle template, forms mould in concrete.

After, slowly vibrator is extracted into concrete.
Vibrating time was controlled at 20 ~ 30 seconds.When concrete no longer significantly sinks, there is not bubble, when starting frost boiling, that is, sentences
Determine concrete vibrating to be completed.
When vibrating to the side mode position of concrete slab, using wooden mallet gently tapping template, to the intensive place of reinforcing bar and mould
When plate edge is vibrated, consolidated with the use of crooked chisel.
When vibrating to concrete lower die, the output shaft of internal vibrator runs through concrete lower die, is inserted into coagulation
5 centimetres to 10 centimetres or so of position in native bottom plate, keeps the connection between concrete lower die and concrete floor stronger.
It when mould and concrete upper mold are vibrated in concrete, also adopts in a like fashion, is inserted into needs and vibrates
Concrete lower layer in, reinforce two layer concretes between connection.
C2: after vibrating at the one of concrete, continue to carry out vibration compacting to its other some position, repeat to grasp
Make, makes monolith concrete slab can vibration compacting.Complete work of vibrating for the first time.
D: solidification.Precast concrete placement is solidified in the natural environment, one is arranged on precast concrete
A baffle prevents damage of the adverse circumstances to prefabricated component.
In concrete in or so initial set previous hour, need to carry out secondary vibration to it.When secondary vibration, internal vibrator
Output shaft from the upper end of concrete upper mold to underthrust, through mould and concrete lower die in concrete, be inserted into concrete floor
It is interior, start to vibrate.
The time of secondary vibration and decision procedure with vibrate for the first time identical, determined according to the actual situation.
Precast concrete is continued to place after secondary vibration and is solidified in the natural environment, is made concrete prefabricated
Part solidifies completely.
E: side mode is detached from.After concrete solidifies substantially, cope plate, middle template and lower template are successively divided with concrete
From stifled Short Item is also extracted from precast concrete, is smoothed to the edge of precast concrete, is made precast concrete
Surface it is more smooth.
