Abstract
The utility model discloses an inserted vacuum suction vibrator for concrete. The front end of a vibrating rod is designed with a vacuum suction cup whose rear part is a cylinder cavity (13) connected with a vacuum pump through a vacuum hard tube (8) and a vacuum hose (5). After started up, the utility model can vibrate while compacting, and absorb water while exhausting air to lower the water-cement ratio and the air content of the concrete. The vacuum pump is used for generating negative-pressures at the suction cup point.
Description
The utility model relates to a kind of building machinery.
Along with the development of town and country construction, in the construction, basis, framework, floor, roofing etc. use concrete in a large number at the scene.
In construction, water for convenience and smash, water/binder ratio is all bigger, mixes concrete very rarely, a large amount of unnecessary " workability water " are arranged, be present in the concrete, simultaneously, also brought some gases in concrete, form many small holes at last, concrete pore is increased, intensity reduces.For the intensity that guarantees to design, often have to add cement and be guaranteed, cause waste.
The utility model is to reduce " workability water " and the air content in the preceding concrete of initial set, can satisfy construction requirement, can guarantee concrete strength again.For this reason, at existing vibrating head front end, a cavity vacuum suction nozzle (1) with holes is housed, and suction nozzle is latter half of to be cylindrical cavity (13), joins by vacuum hard tube (8) and vacuum hose (5) and vacuum pump, the motor and the vacuum pump of vibrator start simultaneously, like this, limit mechanical pudding, limit suction exhaust, reach the air content that reduces in concrete water/binder ratio and the concrete, " watering and smash---draining (gas)---moulding " step is finished.Like this, concrete not only has sufficiently high workability but also have minimum water/binder ratio.
Owing to reduced concrete water-cement ratio, can make and shorten 1/3～1/4 curing period, can improve concrete strength 10～40%, reduce cement consumption, improve form cycling rate, reduce construction costs, accelerating construction progress, overall economic efficiency is good.
Below in conjunction with accompanying drawing in detail, the utility model is described in detail.
Fig. 1 is the vibrating head structure chart
Fig. 2 is a vacuum cups cut-away view with holes
Fig. 3 is a vacuum cups external structure with holes
Fig. 4 is a vacuum cups external structure lateral view with holes.
Vacuum cups (1) front end semicircle partly, be evenly distributed with aperture (14) (shown in Fig. 3), latter half of is cavity cylinder (13), join with vacuum hard tube (8) (making) and cavity cylinder (13) of seamless steel pipe, with vacuum hose (5) (making) and vacuum hard tube (8),, can not leak gas with larynx hoop (6) chucking of pressure-resistant rubber hose, the end of vacuum hose (5) and the air entry of vacuum pump join, and make it whole formation vacuum dehydration (gas) passage.
In order to stop that cement, sand, stone enter in the vacuum passage, inwall in vacuum cups (1), be provided with a fine metal mesh semicircle lid (11) that is complementary with inwall, put the nylon cloth lining (12) of a lock ring in its appearance, use interior pressure (with holes) nut (10) that fine metal mesh semicircle lid (11) is compressed, locatees again.
When vibrator started, vacuum pump was worked simultaneously, after vibrating head inserts in the concrete, because the negative pressure that vacuum pump produced, near workability the water free vacuum cups (1) is gentle, just can enter in the vacuum cups, and discharges outside the concrete through (13), (8), (5).
In order to prevent vacuum failure, between vacuum cups (1) and vibrating head (2) and vacuum cups (1) and vacuum hard tube (8), all be provided with vulcanie seal washer (15), (9) are sealed.
The making of this vibrator is implemented very easily, and the producer of original production immersion vibrator need not increase other new equipment fully, just can drop into batch process.
Claims (4)
1, a kind of plug-in type vacuum dehydration concrete vibrator, form by vibrating head, motor, flexible axle, electric vacuum pump etc., the front end that it is characterized in that vibrating head [2] is equipped with a vacuum cups [1], the cylindrical cavity [13] that suction nozzle is latter half of joins with vacuum pump by vacuum hard tube [8] and vacuum hose [5].
2, vibrator as claimed in claim 1 is characterized in that vacuum cups (1) front end outer wall semicircle partly, is distributed with aperture (14) equably, and the front end semicircle of inwall partly is equipped with the wire gauze semicircle lid (11) that the surface is with nylon cloth lining (12).
3, vibrator as claimed in claim 1 is characterized in that vacuum hard tube (8) is to be processed into seamless steel pipe.
4, vibrator as claimed in claim 1 is characterized in that vacuum hose is to make with pressure-resistant rubber hose.
