A multi-reinforcement integrated layout device suitable for 3D printed concrete structures

Abstract

The invention is a multi-reinforcement integrated layout device suitable for 3D printing concrete structures. The device includes a spiral blade extrusion concrete printing head, a reinforcement feeding unit, a wire pulley, a fixed plate, a reinforcement pipe, a shearing unit, and a control unit. system and multiple wire rope spools. The multiple wire rope spools, wire pulleys, and rebar feeding units are fixed on the fixed plate in sequence from top to bottom. The fixed plate is fixed in parallel to the side of the barrel on the top of the concrete printing head through the fixed ring and connecting rod. on; the shearing unit is fixed on the other side of the barrel opposite to the fixed plate; one end of the reinforcement tube extends from the side wall of the concrete print head to the central axis position of the concrete print head. This device can realize the integrated construction of concrete and multiple steel wire ropes. Multiple steel wire ropes and concrete are extruded through the printing head together. The prepared 3D printed steel wire rope reinforced concrete composite material has high tensile strength and ductility.

Description

technical field [0001] The invention belongs to the field of civil engineering, and specifically relates to a method for strengthening a 3D printed concrete structure, and more particularly relates to a multi-reinforcement integrated layout device suitable for a 3D printed concrete structure. Background technique [0002] In recent years, 3D printing technology has become a hot topic in society, and printing materials include plastics, metals, ceramics, soft materials, concrete, etc. 3D printing concrete technology has many advantages such as free design and construction, high degree of automation, fast construction speed, low labor cost, and low environmental pollution. In recent years, it has received extensive attention and significant development in the field of civil engineering. 3D printed bridges, 3D printed houses, etc. can be seen everywhere, which largely confirm the feasibility of applying 3D printing technology to the field of civil engineering. However, 3D prin...

AI Technical Summary

Problems solved by technology

In order to adapt to the flexibility of the 3D printing path, the diameter of the steel wire rope that meets the requirements of concrete 3D printing is small. However, the size of the print head for 3D printing concrete is large, and the reinforcement provided by a single steel wire rope is limited.
