Grouting device for prefabricated component and construction method thereof

Abstract

The invention discloses a grouting device for a prefabricated component. The grouting device comprises a precast concrete wallboard, a precast concrete beam, a grouting sleeve pre-buried at the bottomof the precast concrete wallboard, and a slurry circulation conveyor mechanism connected with the grouting sleeve. A sleeve outlet is arranged at the top of the grouting sleeve, and a sleeve inlet isarranged at the bottom of the grouting sleeve. The slurry circulation conveyor mechanism comprises a mixing device and a booster pump connected with the mixing device, a slurry inlet and a slurry outlet are formed in the mixing device, the slurry outlet is connected with a conveyor channel, the conveyor channel communicates with the sleeve inlet, the slurry inlet is connected with a backflow channel, and the backflow channel communicates with the sleeve outlet. The slurry circulation conveyor mechanism is arranged to realize the purpose of circulation grouting, the problems such as insufficient grouting inside the sleeve, incomplete bubble elimination, incomplete grouting at the joint or leakage of grouting at a seal chamber are effectively solved, and the connection quality between precast concrete components is improved.

Description

technical field [0001] The invention relates to the field of prefabricated concrete construction engineering technology and detection, in particular to a grouting device for prefabricated components in a prefabricated concrete building and a construction method thereof. Background technique [0002] With the continuous reduction of construction workers and the continuous rise of labor costs, my country has gradually increased its guidance on the development of prefabricated buildings. Vigorously developing prefabricated buildings has become a national development strategy, and the industrialization of prefabricated buildings has become a kind of necessity. [0003] The prefabricated concrete structure is to change the cast-in-place concrete into factory prefabricated processing to form prefabricated beams, columns, slabs and other components, which are then transported to the construction site for hoisting and assembly. The structures are connected by grouting to form an inte...

AI Technical Summary

Problems solved by technology

[0013] In view of the above-mentioned problems existing in the prior art, the purpose is to provide a grouting device for prefabricated components and its construction method. The purpose of circulating grouting can be realized by setting a slurry circulation conveying mechanism connected with the grouting sleeve. The device can effectively solve the problem of Insufficient grouting inside the sleeve and insufficient removal of air bubbles. At the same time, a construction step is set up to detect whether the grouting is sufficient, which can prevent quality defects after sleeve filling caused by insufficient grouting at the joints or insufficient sealing of the warehouse. Problems, effectively improve the quality of connections between precast concrete components
