The invention relates to the technical field of concrete performance detection, and provides a 3D printing concrete constructability detection device, which comprises: a body; the detection structure comprises a detection part and a connection part which are connected, the detection part is exposed out of the body and is suitable for being inserted into to-be-tested concrete, and the connection part is located in the body; the force sensor is arranged in the body, abuts against the end, away from the detection part, of the connection part and is suitable for obtaining the resistance value borne by the detection part when the detection part is inserted into the concrete to be tested; and the data processing system is in signal connection with the force sensor and is suitable for acquiring architectural information of the to-be-tested concrete according to the resistance value. The 3D printing concrete constructability detection device is small in size, light in weight and good in portability, can be carried to a construction site for use, and is higher in applicability; and compared with a concrete rheometer, the concrete rheometer is lower in manufacturing cost and suitable for large-scale popularization and application.
Description
technical field [0001] The invention relates to the technical field of concrete performance detection, in particular to a 3D printed concrete constructability detection device and method. Background technique [0002] 3D printing concrete technology is a brand-new technology that combines 3D printing technology with concrete preparation technology. Its main principle is to use computer to carry out 3D modeling and segmentation of concrete components to produce three-dimensional information, and then mix the prepared concrete The material passes through the extrusion device, according to the set program, through the mechanical control, is extruded from the nozzle for printing, and finally the concrete component is obtained. Different from the high-performance development of traditional cement concrete, the key to the realization of 3D printing of concrete materials for architectural 3D printing is whether the concrete can withstand its own weight and the gravity of the upper ...
