Brace up pound do bad? Concrete quality not firm!

Concrete brace up pound exercise to become bad word, because,concrete structure is met brace up pound not divide evenly, leakage brace up wait for a reason, occurrence facing is loose, be short of the circumstance such as muscle of caustic, dew or break. Concrete is not close-grained, weaken with respect to what create component part section, those who reduce concrete component part bear the weight of force; Additional, subtle hole and cranny, make external moisture and gas invade interior very easily to corrode reinforcing steel bar, bring about a structure to be destroyed prematurely.

Brace up pound the example of beehive hemp face that was not done good and brings about

Because of brace up pound not do one's best to cause quality problem to often happen

Among them a main reason is

The jockey of construction site lacks necessary ABC

Especially right concrete brace up pound equipment and operation craft to undertake unscrambling

In order to offer reference study, promote concrete construction quality!

Concrete is irrigated when building construction, must eliminate among them bleb, undertake tamp, make concrete close-grained union, eliminate the appearance such as the beehive hemp face of concrete, in order to increase its strength, assure the quality of concrete component, concrete vibrator is the machines and tools that mechanization pounds solid concrete. Concrete vibrator basically has 4 kinds: In-house oscillator, surface oscillator, exterior oscillator, shake table.

① in-house oscillator

② surface oscillator

③ exterior oscillator

④ shake table

Building engineering construction site, exterior oscillator and shake table are used less, the article is aimed at building site to get on two commonly used kinds only brace up beat device: In-house oscillator and exterior oscillator, undertake detailed construction operates craft introduction.

In-house oscillator

In-house oscillator also cries " brace up dolly " , can insert irrigate the interior that builds concrete to undertake brace up pound, make concrete is irrigated build brace up pound exercise to use the commonnest tool. Brace up dolly applies to large volume concrete, foundation, column, bridge, wall, ply bigger board, prefabricated components.

"Brace up dolly " divide again for prejudicial type and planetary type two kinds of means: Former it is to use brace up the has prejudicial quality runner shaft that dolly center installs, the centrifugal power that produces when high speed rotates is delivered through bearing brace up pound housing, make thereby brace up dolly generation is circumferential and oscillatory; Latter is to use brace up the runner shaft with dangerous sky of the one aspect of the matter in dolly, when it rotates, the conic share that its prolapse carries rolls along the taper seat inside strong case, the planetary campaign that forms scroll body thereby produces circumferential vibration with drive strong put oneself in another's position.

Exterior oscillator

Exterior oscillator also cries " board type oscillator " , basically use at irrigating to build an area big, ply the work area of small, level off, be like the ground, floor, roofing.

"Board type oscillator " be put equipment in concrete directly apparently, by the oscillatory wave that 2- vibrator generates, through the 1- that secures to it brace up pound motherboard, pass concrete.
