Demountable sleeve grouting connection design and construction method

Abstract

The invention relates to a demountable sleeve grouting connection design and construction method which comprises the following steps: providing a sleeve grouting connection design method, and selecting demountable sleeves and accessories with matched sizes according to the diameters of reinforcements; mounting pre-embedded reinforcements in a first sleeve body, connecting a second sleeve body withthe first sleeve body integrally, binding the embedded reinforcements to form a reinforcement cage, performing concrete pouring to obtain a prefabricated member, mounting to-be-connected reinforcements in the second sleeve body, pouring grouting material from a grouting hole, plugging a grout drain hole and a grouting hole after grout is drained from the grout drain hole to form sleeve grouting connection; and during dismounting, separating the sleeve grouting connection from concrete, cutting off sleeve outer reinforcements, separating the sleeves, extruding the sleeve outer reinforcements and integrally draining the sleeve outer reinforcements along with the grouting material from the sleeves, and recovering and maintaining the sleeves and the accessories. The sleeves can be used twiceor multiple times, the types and the quantities of building wastes in the dismounting process of precast concrete members are reduced, resources are saved, and the environment is protected.

Description

technical field [0001] The invention belongs to the technical field of building design and construction, and in particular relates to a detachable sleeve grouting connection design and construction method. Background technique [0002] With the rapid development of my country's economy, science and technology and the large demand of residents for housing, various types of reinforced concrete buildings are increasing day by day, and the connection forms of steel bars in the process of building construction are also diversified. Lap joints, welded joints, mechanical joints. my country is currently advocating vigorously developing the prefabricated structure system, and the preferential policies for the development of industrialized housing have prompted a large number of real estate developers to develop prefabricated houses, making prefabricated structures account for an increasing proportion of the entire construction industry. [0003] Rebar grouting sleeve connection is th...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a detachable sleeve grouting connection design and construction method in order to solve the above problems, solve the technical problem that the sleeve in the existing prefabricated concrete components cannot be reused, and realize the secondary or even multiple times of the sleeve. Recycling, improving the utilization rate of sleeves, reducing the types and processing difficulties of construction waste in the process of building demolition, reducing energy consumption, saving resources, and protecting the environment
