3d printing process and concrete combined building structure and construction method

Abstract

The invention discloses a 3d (three-dimensional) printing process and concrete combined building structure and a construction method. The construction method comprises the following steps: 1) constructing a digital model of a shell and an internal structure of a building component; 2) performing 3d printing operation on the digital model; 3) pouring concrete to form an integrated structural component with the model which is printed in the step 2), and performing cooperative work; 4) after the building component in the step 3) is formed integrally, deciding whether to remove the shell of the 3d printing model according to engineering requirement, wherein the bare material of the concrete can be used as a model element. According to the 3d printing process and concrete combined building structure and the construction method, the problem that reinforcing steel bars are difficult to manufacture in special-shaped curved surface reinforced concrete construction can be effectively solved; force is transferred explicitly; construction components are reduced; construction processes are simplified; construction cost is reduced.

Description

technical field [0001] The present invention relates to the technical field of building structure, building structure and building 3D printing, in particular to a building structure and construction method combining 3D printing technology and concrete. Background technique [0002] It is well known in the industry that the construction of many traditional building components is very troublesome. For example, the construction of traditional complex hyperboloid components needs to go through measurement and setting out, erection of scaffolding, fabrication and installation of arc-shaped positioning steel pipes, installation of inner formwork, steel bar binding, concrete Complicated steps such as pouring, formwork removal, etc. This traditional construction method has significant limitations: [0003] 1.

Problems solved by technology

[0002] It is well known in the industry that the construction of many traditional building components is very troublesome. For example, the construction of traditional complex hyperboloid components needs to go through measurement and setting out, erection of scaffolding, fabrication and installation of arc-shaped positioning steel pipes, installation of inner formwork, steel bar binding, concrete Complex steps such as pouring, formwork removal, etc.

This traditional construction method has significant limitations:

[0003] 1. Complex hyperboloid components require construction personnel to accurately locate the virtual digital model or plan drawings in physical space, which is prone to errors or errors due to limitations of measurement tools or human factors;

[0004] 2. Due to complex hyperboloid components, construction personnel are required to carry out complex form work, which is difficult and requires the application of a large number of supporting components, and the amount of mold consumables is large;

[0005] 3. Due to the changeable spatial form and uneven force of the complex hyperboloid components, the reinforcement of the wall needs to match the corresponding structural force transmission, resulting in a very complicated distribution of reinforcement and difficult construction

[0010] Therefore, the combination of 3D printing technology and concrete pouring can solve the bottleneck problems of low accuracy, complex construction and high cost of complex hyperboloid components
