AI Technical Summary

Technical Problem

Traditional shear wall construction has the shortcomings of high labor costs, many quality problems, difficulty in adapting to complex-shaped buildings, and insufficient consideration of thermal insulation and other functions.

Method used

Using 3D printing technology, ultra-high performance concrete prints the outer mold and skeleton to form a casting area and fills special functional materials into the cavity of the skeleton to achieve rapid molding and functional improvement of the shear wall.

Benefits of technology

The steps of artificial support and dismantling of molds are reduced, labor costs are reduced, construction efficiency and quality are improved, suitable for complex shape buildings, and the functions of thermal insulation and other functions are improved through special functional materials.

Abstract

The present invention provides a 3D-printed shear wall structure and a construction method, which relate to the technical field of building structures; the shear wall structure comprises outer molds placed on both sides and a skeleton placed in the outer molds, and a casting area is formed between the outer molds and the skeleton; the outer molds and the skeleton are provided with raised units at intervals on one side facing the casting area; the outer molds and the skeleton are formed by 3D printing using ultra-high performance concrete; the cavity part of the skeleton is provided with a cavity for filling with special functional materials; a first steel cage is provided in the casting area, and second steel cages are connected to both ends of the first steel cage, and concrete is cast in the casting area; the outer molds and the skeleton printed by 3D printing with ultra-high performance concrete are used as templates for shear wall casting, and there is no need for manual formwork, so as to avoid leakage of slurry at the root of the wall and uneven shear wall surface caused by inaccurate template installation position due to improper operation of construction personnel.
