Description

Technical Field

[0001] The present invention relates to the field of 3D printing of building components, and in particular to a method for manufacturing building components assisted by 3D printing. Background Art

[0002] With the development of economy and the improvement of people's living standards, the demand of society for architecture is no longer limited to functionality, but more attention is paid to the aesthetic value and cultural significance of architecture. Creative architecture can often become the landmark of the city, enhance the city's image, and attract investment and tourism. However, most creative buildings are often diverse, special-shaped, and personalized in shape, especially special-shaped and curved building components, which have particularly high requirements for construction, while taking into account green design and cost control. For the building components in the above-mentioned creative buildings, the general implementation method is to first adopt the formwork casting mode, or to make molds and then cast them. This kind of implementation method has the following problems and defects: 1. Difficulty in refinement. Generally, templates and molds are made manually, involving various process constraints such as laying out, processing, and production, so it is difficult to achieve refinement. 2. Long production period. For special-shaped templates and molds, workers need to process and make them carefully, which takes a longer time to make and cannot meet the high efficiency requirements. 3. Large waste. The templates and molds made are generally disposable and difficult to reuse, resulting in waste of templates and molds, which does not meet the low-carbon requirements currently advocated by the country, and the waste is large. 4. High overall cost. The production of such building components requires experienced construction workers, and the labor cost is high. At the same time, the templates and molds cannot be reused and can only be considered a one-time investment. Combined with the production period cost, the overall cost is high.

[0003] Therefore, in order to solve the above-mentioned problems, a method for manufacturing building components assisted by building 3D printing is proposed. Summary of the invention

[0004] The present invention is aimed at the above-mentioned problems and specifically designs a method for manufacturing building components assisted by building 3D printing. This method can shorten the construction period and save costs, and can improve the accuracy of building components.

[0005] To achieve the above-mentioned purpose, the present invention provides a method for manufacturing building components assisted by building 3D printing, comprising the following steps: step 1: modeling the shape contour of the building component in a design software according to the shape and size of the building component; step 2: topology and optimization design of the 3D printing model as well as design of the slice and printing path according to the modeled model; step 3: 3D printing the contour of the building component according to the designed path; step 4: tying steel bars in situ of the building component according to the position of the building component to be manufactured; step 5: when the contour of the building component after printing reaches a certain strength and meets the hoisting conditions, the contour of the building component is hoisted and sleeved on the outside of the tied steel bars, and then the contour of the building component is fixed to the base layer; step 6: pouring in the contour cavity of the 3D printed building component.

[0006] Through the above method, you can choose to prefabricate in the factory or make the outline of the building components on the construction site, and flexibly choose according to construction needs. For the production of special-shaped components, the production and installation of special-shaped templates are eliminated, reducing the construction difficulty.

[0007] Furthermore, in step 4 and step 5, in step 4, the vertical steel bars are first tied, and after the outline of the building component is set in step 5, the outline of the building component is first fixed on the base layer, and the vertical and transverse steel bars are fixed and tied to the outline of the building component.

[0008] Furthermore, in the step five, after the outline of the building component is hoisted and mounted on the outside of the vertical steel bars that have been tied and the outline of the building component is fixed, the vertical steel bars are attached to the inner surface of the outline of the building component. Alternatively, after the outline of the building component is fixed, the vertical steel bars are tied to the outside of the outline of the building component so that the vertical steel bars are attached to the outer surface of the outline of the building component, and then the outer surface is coated with a protective coating, and the vertical and transverse steel bars are fixed and tied to the outline of the building component.

[0009] Through the above method, after the steel bars inside the special-shaped components are tied, they need to fit the inner wall of the building component contour as much as possible to improve the stability of the overall structure. Therefore, the steel bars are tied in sections, and the horizontal steel bars are tied after the vertical steel bars are corrected by fitting the contour of the building component.

[0010] Furthermore, in step five, the outline of the building component is fixed to the base by using fixing bolts and / or implanted reinforcement.

[0011] Furthermore, the steel bar component includes vertical steel bars and transverse steel bars. After the vertical steel bars are tied, the outline of the building component is placed within the outline surrounded by the vertical steel bars, the vertical steel bars are attached to the outer surface of the outline of the building component, and then the transverse steel bars are tied. The outline of the building component is then fixed to the base layer, the steel bar component is located on the outer surface of the outline of the building component, and then a protective layer is applied to the outer surface of the outline of the building component.

[0012] In the above manner, special-shaped components with complex structures cannot be manufactured through a 3D printed outline, and need to be manufactured multiple times and then assembled. When assembling, vertical steel bars are required for connection.

[0013] Furthermore, when a building component requires multiple contours for segmented implementation, to ensure that the contour of the building component has a certain strength and does not bulge or deform after pouring, repeat steps three to five, and then proceed to step six for overall pouring and forming, splicing the contours of each building component and pouring caulking material between the gaps between the contours to fill them.

[0014] Furthermore, when a building component requires multiple contours for segmented implementation, to ensure that the building component contour has a certain strength and does not bulge or deform after pouring, repeat steps three to six, splice the contours of each building component and pour caulking material between the gaps between the contours to fill them.

[0015] The present invention also provides a 3D printed special-shaped building component, comprising a building component outline and a steel bar component, wherein the steel bar component is fixedly arranged on a base layer, the building component outline is sleeved on the outside of the steel bar component and the building component outline is fixedly connected to the base layer.

[0016] Furthermore, the steel bar component includes vertical steel bars and transverse steel bars, the vertical steel bars are arranged in close contact with the inner surface of the outline of the building component, and the transverse steel bars are arranged around the vertical steel bars.

[0017] Furthermore, the outline of the building component is fixedly connected to the base layer by bolts and / or embedded steel bars.

[0018] In summary, the method for manufacturing building components assisted by 3D printing of the present invention has the following advantages and beneficial technical effects: 1. The present invention discloses a method for manufacturing building components by 3D printing to assist in manufacturing building components. The method can avoid the production of special-shaped templates for special-shaped components that are difficult to manufacture, thereby reducing the difficulty of construction. The method is believed to be more capable of realizing the refinement of building manufacturing because the complex process involved in making templates can easily cause errors. 2. The method for manufacturing building components assisted by 3D printing of the present invention saves costs. The outline of the 3D printed building component becomes a part of the component, replacing the function of a disposable template, and has a greater advantage in saving construction costs; 3. The segmented construction of steel bar binding in the method for manufacturing building components assisted by building 3D printing of the present invention makes the steel bar structure more adaptable to the contour of the building components and improves the stability of the overall structure after casting; 4. The method for manufacturing building components assisted by 3D printing of the present invention can manufacture more complex special-shaped structures by printing the outline of the building components multiple times.

[0021] In order to make the purpose, technical scheme and advantages of the implementation of the present invention clearer, the technical scheme in the embodiment of the present invention will be described in more detail below in conjunction with the drawings in the embodiment of the present invention. In the drawings, the same or similar reference numerals throughout represent the same or similar elements or elements with the same or similar functions; the described embodiments are part of the embodiments of the present invention, not all of the embodiments; the embodiments described below with reference to the drawings and directional terms are exemplary and intended to be used to explain the present invention, and cannot be understood as limitations on the present invention; based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. The parts and equipment all adopt conventional models in the prior art and will not be described in detail here. The contents not described in detail in this specification belong to the prior art known to professional and technical personnel in this field. The embodiments of the present invention are described in detail below in conjunction with the drawings: like Figure 1 , Figure 2 and Figure 3As shown, a method for manufacturing building components assisted by building 3D printing comprises the following steps: Step 1: Model the shape and outline of the building components in the design software according to their shape and size; Step 2: Perform topology and optimization design of the 3D printing model as well as design of slicing and printing path based on the modeled model; Step 3: 3D printing the outline 1 of the building component according to the designed path; Step 4: according to the position of the building component to be manufactured, tying the steel bar component 2 in the original position of the building component; Step 5: When the printed building component outline 1 reaches a certain strength and meets the hoisting conditions, the building component outline 1 is hoisted and placed on the outside of the already tied steel bar component 2, and then the building component outline 1 is fixed to the base layer; Step 6: Casting in the cavity of the 3D printed building component outline 1.

[0022] The material of the building component outline of 3D printing is not limited to concrete materials, and can be various materials that can be 3D printed, such as caulking materials, ceramics, polymer materials, etc. The above-mentioned steel bars can also be other materials, such as fiber bars, fibers, and other materials with high tensile strength. The casting of the material in the outline cavity of the 3D printed building component can also be done by injection or coating.

[0023] The outline of the building component can be prefabricated in the factory or made on the construction site. The choice can be flexibly made according to the construction needs. The prepared building component outline 1 is put on the outside of the steel component 2. After being fixed through the process, the inside of the building component outline 1 is filled with concrete and vibrated. For the production of special-shaped components, the production and installation of special-shaped templates are eliminated, which reduces the construction difficulty and improves the construction accuracy.

[0024] like Figure 1 As shown, in step 4 and step 5, the steel bar component 2 in step 4 includes vertical steel bars 3 and transverse steel bars 4, and the vertical steel bars 3 are tied first. After the building component outline 1 is set in step 5, the building component outline 1 is first fixed on the base layer, and the vertical steel bars 3 and transverse steel bars 4 are fixed and tied to the building component outline 1.

[0025] like Figure 1As shown, in step 5, after the building component outline 1 is hoisted and set on the outside of the vertical steel bars 3 that have been tied and the building component outline 1 is fixed, the vertical steel bars 3 are attached to the inner surface of the building component outline 1, and the vertical steel bars 3 and the transverse steel bars 4 are fixed and tied with the building component outline 1. After the steel bars inside the special-shaped component are tied, they need to fit the inner wall of the building component outline 1 as much as possible to improve the stability of the overall structure. Therefore, the steel bar tying is carried out in sections, and the vertical steel bars 3 are corrected by fitting the inner wall of the building component outline before the transverse steel bars 4 are tied. After the initial steel bar tying is completed, it is impossible to fit the outside of the high-precision building component outline 1 of 3D printing. Therefore, after the building component outline 1 is set and fixed, the vertical steel bars 3 are manually corrected so that the inner surface of the entire building component outline 1 is supported and provided with steel bars, thereby improving the stability of the overall component and laying the foundation for subsequent concrete pouring.

[0026] like Figure 1 As shown, in step 5, the building component outline 1 is fixed to the base by using fixing bolts. In order to facilitate the subsequent vertical reinforcement 3 to be more firmly attached to the inner surface of the building component outline 1, the building component outline 1 needs to be fixed first to provide a stable fulcrum for subsequent attachment.

[0027] The steel bar component 2 includes vertical steel bars 3 and transverse steel bars 4. After the vertical steel bars 3 are tied, the building component outline 1 is placed in the outline surrounded by the vertical steel bars 3, the vertical steel bars 3 are attached to the outer surface of the building component outline 1, and then the transverse steel bars 4 are tied. Then, the building component outline 1 is fixed to the base layer, the steel bar component 2 is located on the outer surface of the building component outline 1, and then a protective layer is applied to the outer surface of the building component outline 1.

[0028] A special-shaped component with a complex structure cannot be manufactured by a 3D printed building component outline 1, and needs to be manufactured multiple times and then assembled. When assembling, vertical steel bars 3 need to be used for connection.

[0029] like Figure 1 As shown, when the building component requires multiple profiles for segmented implementation, ensure that the building component profile 1 has a certain strength and does not bulge or deform after pouring, repeat steps 3 to 5, and then proceed to step 6 for overall pouring and forming, splice the individual building component profiles 1 and pour filler materials between the gaps between the profiles to fill them.

[0030] When the building component requires multiple profiles for segmented implementation, when the poured material in step 6 reaches the strength requirement, repeat steps 3 to 6, splice the profiles 1 of each building component and pour the caulking material between the gaps of the profiles to fill them. The above two methods are selected according to the on-site construction conditions and construction requirements.

[0031] The present invention discloses a 3D printed special-shaped building component, comprising a building component outline 1 and a steel bar component 2, wherein the steel bar component 2 is fixedly arranged on a base layer, the steel bar component 2 is a component pre-positioned on the base layer, the building component outline 1 is sleeved on the outside of the steel bar component 2 and the building component outline 1 is fixedly connected to the base layer.

[0032] The reinforcement member 2 includes vertical reinforcements 3 and transverse reinforcements 4 . The vertical reinforcements 3 are arranged in close contact with the inner surface of the building member profile 1 , and the transverse reinforcements 4 are arranged around the vertical reinforcements 3 .

[0033] The building element profile 1 is fixedly connected to the base by means of bolt connection.

[0034] Finally, it should be pointed out that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them. Although the present invention has been described in detail with reference to the above embodiments, a person skilled in the art should understand that the technical solutions described in the above embodiments can still be modified, or some of the technical features can be replaced by equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
