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

Abstract

The invention relates to a multi-bar integrated arrangement device suitable for a 3D printed concrete structure. The multi-bar integrated arrangement device comprises a spiral-blade-type extrusion concrete printing head, a bar feeding unit, a wire guiding wheel, a fixing plate, a bar conveying pipe, a shear-off unit, a control system and a plurality of steel wire rope spools; the multiple steel wire rope spools, the wire guiding wheel and the bar feeding unit are sequentially fixed to the fixing plate from top to bottom; the fixing plate is parallelly fixed to the side face of a charging basket above the printing head through a fixing ring and a connecting rod; the shear-off unit is fixed to the other side face, opposite to the fixing plate, of the charging basket; and one end of the bar conveying pipe extends into the middle axis of the concrete printing head from the side wall of the concrete printing head. According to the multi-bar integrated arrangement device, integrated construction of concrete and a plurality of steel wire ropes can be achieved, the multiple steel wire ropes and the concrete are extruded together through the printing head, and a prepared 3D printed steel wire rope reinforced concrete composite 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...

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.
