Abstract

The invention provides a 3D printing concrete constructional column bottom vertical steel bar anchoring component and a construction method, a combined steel sleeve prefabricated part of the anchoring component is pre-buried on a concrete beam or plate, a plurality of lap joint steel bars are longitudinally placed in the combined steel sleeve prefabricated part, each fixing plug pin prefabricated part is installed on one lap joint steel bar, and a plurality of fixing plug pin prefabricated parts are installed on the corresponding lap joint steel bar. A prefabricated reinforcement cage is installed on the lap joint steel bars, lap joint end plate prefabricated parts are installed on the lower portion of the reinforcement cage, and the vertical lap joint steel bars and the reinforcement cage are further fixed through lap joint of the fixing plug pin prefabricated parts and the lap joint end plate prefabricated parts. The construction problem of a 3D printing concrete constructional column root joint provided with vertical steel bars is solved, the bottom vertical steel bar anchoring component of the 3D printing concrete constructional column and the construction method are provided, and the construction method is provided for improving the joint strength of a 3D printing concrete vertical component.

Description

technical field [0001] The invention relates to a 3D printed concrete structural column bottom vertical reinforcement anchor component and a construction method, belonging to the technical field of anchor components. Background technique [0002] 3D printing concrete technology is a new achievement in the field of construction engineering in recent years. It has the advantages of fast construction speed, high degree of automation and high social benefits. The transformation of technology-intensive industries has realized the transformation and upgrading of the traditional construction industry. Therefore, the research on 3D printing concrete construction technology is of great significance. For the 3D printed concrete vertical components of the contour process, the configuration of vertical reinforcement plays an extremely important role in ensuring its ductility and integrity. However, the configuration of vertical reinforcement makes the joint construction of 3D printed ...
