Description
Technical field
The invention belongs to technical field of concrete construction.
Background technology
Concrete, referred to as " concrete (t ó ng) "：Refer to that will be gathered materials cementing integral engineered composite material by cementitious material
General designation.One word of concrete usually said refers to making cementitious material with cement, and sand, masonry gather materials；With water (additive can be contained and mixed
Close material) coordinate by a certain percentage, it is agitated obtained by cement concrete, also referred to as normal concrete, it is widely used in building work
Journey.
It needs first to pour into concrete in template when concrete construction, but due to the frictional force and cohesion between gathering materials
Effect, concrete can not be full of template automatically, inside be loose, at this moment need that concrete vibrate to be molded and could assign
Give concrete product or certain shape, intensity, impermeability and the durability of structure.Existing concrete vibrating molding is to use
It is micro- in vibrating spear insertion concrete to shake, so that aggregate particle therein is vibrated by forced, reduces the frictional force between gathering materials and cohere
Power excludes the gas in concrete, eliminates gap so that concrete forms fine and close structure in template again.This mode lacks
Point is：The depth of some concrete blindings (being usually flute profile template) is larger, with certain range office when vibrating spear vibrates
Sex-limited, micro- shake can gradually weaken, deep part, side for concrete when concrete transmits with being incremented by for distance is transmitted
Angular position etc. can not vibrate, and cause the local dense effect of concrete bad, the final overall performance for influencing concrete.
Invention content
The invention is intended to provide a kind of concrete branch densification process improving concrete compaction effect.
Concrete branch densification process in this programme, includes the following steps：
1. concrete is pumped to by filling concrete pipe in mold by concrete pump-feed agent；
2. turning motor starts, cam rotation, micro- vibration tube that extruding contacts when the convex surface of cam, in micro- vibration tube and its
Displacement between the filling concrete pipe in portion changes, and after the convex surface of cam is disengaged with micro- vibration tube, micro- vibration tube returns
Restore position；Repeatedly so that micro- vibration tube around cam vibrates, and the vibration of micro- vibration tube makes the concrete in mold
It is gradually closely knit；
3. after being increased to the lower end of filling concrete pipe with the height of mold inner concrete, starting electric rotating machine, rotation
Motor rotates clockwise so that rack moves up, and linkage board moves up, and filling concrete pipe gradually moves up, and micro- vibration tube is also filled in concrete
It notes and is gradually moved up under the drive of pipe；
4. repeating 1. 2. 3. step, it is finally completed the perfusion of the concrete in mold and closely knit.
Advantageous effect：This method realizes the multiple spot filling concrete to mold using several filling concrete pipes, when mixed
When solidifying soil is gone out out of adjacent filling concrete pipe, mutual impact force makes concrete be squeezed, and concrete obtains
To preliminary micro- vibrating device that is closely knit, and being arranged on filling concrete pipe, cam continuously squeezes micro- vibration tube around cam, micro- to shake
Pipe, which is squeezed, to be vibrated, and to become dense the concrete vibrating around micro- vibration tube, is vibrated by peripheral hardware compared to traditional
Stick progress is closely knit, and the multiple spot that concrete can be realized in this method while multiple spot is perfused is closely knit, the closely knit effect in part of concrete
Fruit is good.And one layer concrete of perfusion can carry out it is micro- shake closely knit, rather than carry out closely knit, therefore also do not deposit after the completion of perfusion
The problem for causing dense effect bad compared with deep because of concrete stated in the background.
Further, the setting of filling concrete pipe lower end is provided with confession there are two with radial limiting stand on micro- vibration tube
The perforative limit hole of the limiting stand, so that the micro- vibration tube contacted with cam contact vibrates.
Further, there are the gaps of 5cm between the inner circle and the outer circle of filling concrete pipe of micro- vibration tube, shake as micro-
The oscillation space of pipe.
Further, several turning motors are installed on the linkage board, turning motor driving cam rotates, so that with
Micro- vibration tube of cam contact contact vibrates.
Description of the drawings
Fig. 1 is the structural schematic diagram of the closely knit mechanism of this concrete branch；
Fig. 2 is the connection diagram of micro- vibration tube and filling concrete pipe in Fig. 1.
Specific implementation mode
Below by specific implementation mode, the present invention is described in further detail：
Reference numeral in Figure of description includes：Mold 1, driving gear 2, rack 3, linkage board 4, filling concrete pipe
5, micro- vibration tube 6, micro- spring 7 that shakes, limiting stand 8, turning motor 9.
Embodiment uses the closely knit mechanism of concrete branch as shown in attached drawing 1, Fig. 2：Including be arranged in rack mold 1,
Mobile mechanism and micro- structure of shaking.
Wherein mold 1 has been fastened by bolts side plate, has been loosered a bolt by horizontal bottom plate, the surrounding of bottom plate, can be by side
Plate is disassembled from bottom plate, realizes the demoulding of concrete, these side plate upper ends surround the opening of 1 upper end of mold.
Mobile mechanism includes electric rotating machine, driving gear 2, rack 3 and linkage board 4.The output shaft of electric rotating machine and active
2 flat key of gear connects, the flank engagement of the driving gear 2 and vertical rack 3.The rear flank of the rack 3 is welded with horizontal
Linkage board 4, it is evenly distributed on the linkage board 4 to there are several filling concrete pipes 5, the upper end of the filling concrete pipe 5 to pass through hose
The lower end outer of external concrete pumping machine, filling concrete pipe 5 forms two limiting stands 8, which is located at concrete filling
Note pipe 5 it is same radially.
It is cased with micro- vibration tube 6 outside filling concrete pipe 5, the limit hole being inserted into for limiting stand 8 is provided on micro- vibration tube 6.It is micro- to shake
There are the gap of 5cm between the inner circle and the outer circle of filling concrete pipe 5 of pipe 6, uniformly distributed in 6 upper end inner circle of micro- vibration tube there are six the
Second spring mounting groove there are six being opened in one spring mounting groove, filling concrete pipe 5 and the contour outer circle of the mounting groove is opposite
