Concrete continuous-blanking subsection-casting device

Abstract

The invention discloses a concrete continuous-blanking subsection-casting device. The concrete continuous-blanking subsection-casting device comprises a front support plate and a rear support plate which are fixed on a concrete casting template. A plurality of limiting plates is installed between the front and rear support plates. The lower part of each limiting plate is rotatably connected with the front and rear support plates. While each limiting plate arrives to the working position, a plurality of the limiting plates is inclined to two directions, two neighboring limiting plates which are contacted mutually are used as one group for cooperation use, and two neighboring limiting plates which are not contacted mutually are used as one pair for cooperation use. A blanking clearance is formed between each pair of the limiting plates. The concrete is fallen from the blanking clearance in the casting process. The concrete continuous-blanking subsection-casting device further comprises a driving device for driving each limiting plate to be rotated. The concrete continuous-blanking subsection-casting device is capable of realizing the continuous blanking process of the concrete and the casting subsection, effectively improving the uniformity of the concrete aggregate distribution, and improving the quality of the concrete.

Description

technical field [0001] The invention belongs to the technical field of building construction, and in particular relates to a step-by-step concrete pouring equipment for continuous blanking. Background technique [0002] With the popularity of high-efficiency water reducers, large-fluid concrete produced by conventional materials and mixing processes has been rapidly promoted in structures. The higher the water reducing rate of the water reducing agent, the more obvious the fluidity and cohesion of the concrete are affected by the fluctuation of water consumption, which also leads to a large number of concrete structures, the top surface laitance is serious, the aggregate sinks, and the concrete quality is reduced. The homogeneity of the concrete will directly result in plastic shrinkage cracking and drying shrinkage cracking, which seriously affect the performance of concrete. Large fluid concrete has good fluidity and requires much less vibrating work than conventional dry...

AI Technical Summary

Problems solved by technology

[0003]For subway side walls, box girder webs, or T-beam webs, etc. The inside of the formwork is vibrated, and the concrete has to flow through a long distance to reach the end, and the first to reach the end is often water, air bubbles, and slurry, and the aggregate is seriously lagging behind

However, this problem can be reduced to a certain extent by the intermittent cutting of materials by workers, but this will seriously affect the pouring speed, prolong the construction time of concrete, and may cause other quality problems
