Embodiment 1

[0042] This embodiment takes the example of printing a woven anti-seismic structural column.

[0043] Step 1: After modeling the seismic structural column modeling space, optimize the space shape according to the functional requirements, and design the weaving density of the wires according to the bearing capacity requirements.

[0044] The second step: according to the determined space shape and weaving density, arrange the printing sequence of the substrate and the anchor points of the wires to obtain the integrated process of printing and weaving; and prepare 3D printing materials.

[0045] Step 3: Print the solid composite column layer by layer according to the integrated process of printing and weaving.

[0046] Specifically, as figure 1 The printing and weaving integration process shown is:

[0047] (2-1) Print the substrate outward / inward;

[0048] (2-2) Spray screw positioning at the anchor point;

[0049] (2-3) Inward / outward integrated printing of braided weft wi...

Embodiment 2

[0055]In this embodiment, the shell 1 of the woven space composite column is 3D printed and combined with the existing reinforced concrete structural column.

[0056] Step 1: Design of the overall structure of special-shaped columns: Firstly, design the special-shaped columns and their shells according to the requirements of architectural modeling, such as image 3 As shown; according to the structure, interlayer shear resistance and stiffness requirements during the construction period, the thickness of the special-shaped column shell and the size and density of the ribs are determined, and the weaving density is designed according to the requirements of crack resistance, deformation and bearing capacity.

[0057] Step 2: According to the determined space shape and weaving density, arrange the printing sequence of the substrate and the anchoring points of the wires to obtain the integrated process of printing and weaving.

[0058] The integrated process of printing and weavin...

Abstract

The invention discloses a construction method of a composite column integrally formed by 3D printing and knitting and the composite column. The construction method comprises the steps that (1) after spatial modeling according to the architectural model, spatial shape optimization is performed according to the functional requirements, and the wire knitting tightness is designed according to the bearing capacity requirements; (2) according to a determined spatial shape and the determined knitting tightness, a matrix printing sequence and anchoring points of wires are arranged to obtain a printing and knitting integrated process, and 3D printing materials are prepared; and (3) according to the printing and knitting integrated process, a solid composite column or a column shell is printed layer by layer. According to the construction method of the composite column integrally formed by 3D printing and knitting, the high-strength wires are knitted in when printing a matrix, and the tensile resistance, shear resistance, abrasion resistance and crack resistance properties of the 3D printing matrix are improved while replacing a steel bar.

Description

technical field [0001] The invention relates to the technical field of building structures, in particular to a construction method of a 3D printing and weaving integrally formed composite column and the composite column. Background technique [0002] The column is the main vertical load member in the structural frame, which bears the load transmitted by the beam and slab and transmits it to the foundation. The stability and safety of the column under various load combinations is a necessary condition for the integrity of the spatial structure, and it is also a key stressed member of the structural analysis. [0003] The vertical force-bearing components of existing building structures are mainly formed by direct printing of 3D printing materials. The lack of combination of these printing materials and traditional reinforcement materials, such as steel bars, results in the limited material properties of printed buildings, mostly single-layer or multi-layer. Small civil build...
