Abstract
The invention relates to a method for napping by using a brushing retarder. The method comprises the following steps of: before napped concrete is cast and compacted, coating the retarder at the position required to be napped on a die, and casting and compacting the concrete; and after the die is disassembled, washing the position required to be napped by using a high-pressure water gun to remove mortar which is not firmly coagulated on the surface of the concrete, so that an aggregate is exposed. Compared with the prior art, the method has the advantages that: an obvious defect of influencing the bonding firmness of the concrete which is cast and compacted for the second time directly due to different depths at the position required to be napped caused by high labor intensity and non-ideal effects in the manual napping process is overcome, the labor intensity of napping is relieved greatly, the bonding firmness of the concrete which is cast and compacted for the second time is enhanced, the napping operation of a bonding surface of precast members and the die is realized, and the bonding firmness consistency of the integral precast members is controlled effectively, so that the quality of the precast members is improved obviously.
Description
Technical field
The present invention is with the method for brushing set retarder plucking, and what relate to is the technical field of building construction, particularly the technical field of assembled integral dwelling house.
Background technology
At present, in the domestic site operation process, concrete plucking adopts manual work to carry out plucking more; Labour intensity is big, and effect is undesirable, and causing needs the deep mixed of plucking position; Directly influenced the secondary disturbing concrete and combined firmness, prefabricated components adopt artificial plucking, can't realize with the plucking of mould faying face; Be difficult to control the uniformity that whole prefabricated components combine fastness, the total quality requirement that can't improve prefabricated components is difficult to adapt to whole assembled-type house modernization request.
Summary of the invention
The objective of the invention is to overcome above-mentioned defective,, provide a kind of simple and efficient brushing set retarder to be used as the method with brushing set retarder plucking of plucking according to the specification requirement of precast wall body.It is characterized in that: its plucking method is before the plucking casting and compacting of concrete, on the mould that needs the plucking position, to coat set retarder; Disturbing concrete behind the dismounting mould, washes with giant at the position that needs plucking again; Remove the concrete surface firm mortar that do not condense, make aggregate exposure.Obvious advantage and the effect of implementing this invention are: at first overcome the employing manual work and carried out plucking; Labour intensity is big, and effect is undesirable, and causing needs the deep mixed of plucking position; Directly influenced the open defect of secondary disturbing concrete combination firmness; The labour intensity of plucking alleviates greatly, has improved secondary and has watered the concrete combination firmness of smashing, and realizes the plucking work with the mould faying face; Effectively the whole prefabricated components of control combine the uniformity of fastness, thereby have improved the quality of prefabricated components significantly.
Description of drawings
Fig. 1 is the structural representation of the present invention's brushing set retarder in mould;
Fig. 2 is the sketch map of xoncrete structure behind the plucking of the present invention;
Wherein, 1-mould, 2-set retarder, 3-aggregate, 4-mortar
The specific embodiment
Below in conjunction with accompanying drawing, be example with the prefabricated components plucking, the present invention is further described:
See accompanying drawing 1,2, brushing set retarder 2 on the mould 1, the xoncrete structure behind the plucking are in the concrete of plucking aggregate 3 and mortar 4 compositions, exposed aggregate 3.
See accompanying drawing 1,2, with the plucking of mould disturbing concrete prefabricated components, before casting and compacting of concrete; On the mould that needs the plucking position, coat set retarder; Disturbing concrete behind second day dismounting mould, washes with giant at the position that needs plucking again; Remove the concrete surface firm mortar that do not condense, make aggregate exposure.Reach the purpose of plucking, the raising secondary waters the concrete of smashing and combines firmly effectively to control the uniformity that whole prefabricated components combine fastness.
