Abstract

The invention discloses a rolling rake type plain concrete leveler. The rolling rake type plain concrete leveler comprises a drum, and is characterized in that long tooth rolling rakes and short tooth rolling rakes are combined for molding on the peripheral surface of the drum; the long tooth rolling rakes consist of multiple long teeth arranged around the peripheral surface of the drum; the short tooth rolling rakes consist of multiple short teeth arranged along the peripheral surface of the drum; the long teeth are arranged along the periphery of the drum according to tooth phase different angles of 5 degrees; and the short tooth rolling rakes in different positions on the drum are arranged at intervals. The rolling rake type plain concrete leveler realizes a more smooth concrete structure layer with uniform compactness through stirring and height limiting effects of long and short rake teeth by rolling of the drum.

Description

One rolls rake plain concrete evener

Technical field

One rolls rake plain concrete evener, and the construction for large area foundation pad flattens, and by cylinder and long and short roll extrusion and limit for height of rolling rake teeth, playing rolls stirs and utilizes gravity pressing effect, belongs to foundation construction engineering field.

Background technology

Large-area plain concrete is built, due to reasons such as concrete mobility, by manually vibrating and adjusting concrete mobility, the uniformity etc. of compactness can not be ensured, sometimes excessive mobility can cause concrete disintegration, directly affects the quality of concrete work.

Summary of the invention

The object of the present invention is to provide a kind of can stir time ensure concrete density, improve workmanship roll rake plain concrete evener.

For achieving the above object, the present invention adopts following technical scheme: one rolls rake plain concrete evener, comprise cylinder, described roll circumference face adopts long tooth roll rake and roll rake combination forming with short tooth, described long tooth rolls rake and is made up of some long teeth along roll circumference face is arranged, described short tooth rolls rake and is made up of along the short tooth on roll circumference face some, the long tooth that described cylinder is circumferentially arranged is arranged according to the angle of tooth phasic difference 5 degree, and on described cylinder, the short tooth of diverse location rolls rake and adopts compartment layout.

On described rolling drum surface, the long and short tooth of lateral arrangement rolls that rake rolls rake according to a long tooth successively, three short teeth roll rake, a long tooth rolls rake and combines.

The length that described long tooth rolls the long tooth of rake is 2 times that described short tooth rolls the short tooth of rake.

The longitudinal pitch that described long and short tooth rolls rake is 150mm.

Beneficial effect: adopt the present invention, by stirring and the limit for height effect of long and short rake teeth, add the roll extrusion of cylinder, realizes compactness evenly and comparatively smooth concrete.

Accompanying drawing illustrates:

Fig. 1 represents that long tooth rolls rake,

Fig. 2 represents that short tooth rolls rake

Fig. 3 be combination after roll rake.

Detailed description of the invention

Below, in conjunction with example, substantive distinguishing features of the present invention and advantage are further described, but the present invention is not limited to listed embodiment.

Make rake cylinder, long tooth 2 length that a kind of long tooth rolls rake 1 is 50mm-150mm, and the length that a kind of short tooth rolls the short tooth 4 of rake 3 is 25mm-75mm; By cylinder 5 center of circle, become radial, 15 degree, interval arranges a rake teeth, and long and short tooth rolls rake about longitudinal separation 150mm; Long tooth rolls rake 1+ tri-short teeth and rolls rake 2 and form a little combination.

The tooth phasic difference 5 degree of rake is rolled in the tooth position that second long tooth rolls rake than first long tooth, longitudinally be arranged in order down, ensure stability in roll and the continuity of same absolute altitude, roll insertion three short teeth between rake 1 at two long teeth and roll rake 3, the tooth position that short tooth rolls rake 3 is alternate setting, play the effect of stirring, spread gravity pressing plate after rolling rake, play compaction.

Cylinder 5 rolls on smooth base plate, long tooth 2 has the effect of stirring and limiting concreting height, short tooth 4 mainly stirring action, short tooth 4 is adopted also to be the resistance that the density in order to not destroy lower concrete stirs with minimizing and rolls, the gravity pressing plate dragged below can further compacted concrete, and this technology is also applicable to the construction of Stabilized Soil bed course.

The above is only the preferred embodiment of the present invention, it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention, can also make some improvements and modifications.
