The invention relates to a bubble guide type concrete bubble exhaust device which comprises an adjustable base. Advancing steel plates for placing a trolley are arranged on the adjustable base. The distance between the advancing steel plates is matched with the distance between wheels of the trolley. A motor is arranged on the top of the trolley and drives the trolley to advance or retreat. The end, close to the trolley tail, of the trolley is provided with a bubble exhaust structure. The bottom, close to the trolley tail, of the trolley is provided with a stirring structure. The bubble guidetype concrete bubble exhaust device further comprises a pressing plate fixed to the trolley tail end of the trolley and obliquely installed so as to cover the bubble exhaust device. The defects that the manual vibrating bubble exhaust effect is low, bubble exhausting is not uniform and the density is affected by a floor concrete construction vibrating device are overcome; through the advancing ofa bubble exhaust part, the bubble exhaust efficiency is improved, and the concrete quality is improved.
Description
Technical field[0001]The invention relates to an air-entrained concrete exhaust device, which belongs to the field of concrete construction.Background technique[0002]At present, the air exhaust method commonly used in the construction of slab concrete is manual vibrating, which has low exhaust efficiency, requires a long time for vibrating and often produces uneven exhaust.[0003]In order to overcome the shortcomings of manual vibrating, there is a concrete construction vibrating device. For example, the Chinese invention patent with the publication number CN106049878A discloses a device driven by a trolley and equipped with multiple vibrators. This invention has defects that affect the density of concrete, and cannot meet the engineering quality requirements.Summary of the invention[0004]The invention provides an air-entrained concrete exhaust device, which overcomes the defects such as low exhaust efficiency of manual vibrating, uneven exhaust, and the impact of compactness of floo...
