Description

Technical Field

[0001] The utility model belongs to the technical field of building construction, and specifically relates to a 3D printing formwork system for curved special-shaped columns. Background Art

[0002] With the gradual improvement of people's architectural aesthetics, the design of various curved and special-shaped structures is common in various important buildings. In addition, the current construction field has gradually increased the requirements for structural forming effects, as well as the requirements for bare concrete effects in key parts. The formwork, reinforcement and forming quality control of curved and special-shaped structures are common technical difficulties.

[0003] Currently, the majority of commonly used column formwork supports are designed for rectangular columns, making curved and irregularly shaped columns more challenging to form. Firstly, the irregularities of the surrounding and supporting components make it difficult to assemble and form them to the desired accuracy using standard formwork materials. Secondly, the uneven stress distribution of curved and irregularly shaped support components necessitates higher strength and reinforcement reliability. Using aluminum or steel formwork as support components for curved and irregularly shaped columns requires sophisticated processing techniques and a supporting reinforcement system. The formwork itself is heavy, requiring large-scale equipment and resulting in high construction costs. Utility Model Content

[0004] In response to the above-mentioned problems in the prior art, the present application proposes a 3D printing formwork system for curved and special-shaped columns. The inside of the template precisely fits the curved and special-shaped columns, and the outside of the template converts the curve into a rectangle. The reinforcement of the curved and special-shaped columns is converted into the reinforcement of ordinary rectangular columns, which solves the difficulties in implementing traditional formwork systems for curved and special-shaped columns.

[0005] The present invention proposes a 3D printing formwork system for curved special-shaped columns, comprising a housing member and a support member; the support member is surrounded on the outside of the housing member, and the inner horizontal cross-section of the support member is a rectangular frame; the housing member comprises a plurality of curved special-shaped polymer templates and a plurality of conversion reinforcement ribs: the plate surface of the curved special-shaped polymer template is fitted with the contour surface of the curved special-shaped column to be cast, and the plurality of curved special-shaped polymer templates are enclosed and spliced ​​to form the cross-sectional contour of the curved special-shaped column to be cast; the conversion reinforcement rib is supported between the curved special-shaped polymer template and the support member, and the conversion reinforcement rib is connected to the curved special-shaped polymer template.

[0006] Furthermore, each of the curved special-shaped polymer templates and the conversion reinforcement ribs on its outer side are a 3D printed integrated molding structure.

[0007] Furthermore, the outer horizontal cross-section of the enclosure member is a rectangular frame, which fits the inner side of the support member.

[0008] Furthermore, the spacing between the multiple conversion reinforcement ribs on the periphery of the curved special-shaped polymer template is 100-200 mm.

[0009] Furthermore, the supporting member includes a square column formwork reinforcement member, and the square column formwork reinforcement member is arranged in multiple groups at intervals along the height direction of the enclosure member, and each group includes two sets of right-angle clamps relatively clamped on the periphery of the enclosure member.

[0010] Furthermore, the supporting member includes square and round buckles.

[0011] The beneficial effects of the present invention are as follows: a plurality of curved special-shaped polymer formworks are enclosed and spliced ​​to form the cross-sectional profile of the curved special-shaped column to be cast, which can be applied to various curved special-shaped concrete columns, can be quickly assembled and installed at the construction site after being manufactured in advance, is easy to operate and does not require professional training. Compared with other standardized formworks, the formworks made of polymer composite materials are strong, precise, and lightweight, and can be effectively applied to various curved special-shaped columns to avoid damage to the material due to uneven force. No large site is required for on-site assembly, and the assembly is simple and fast. No large equipment is required to assist in construction, which is energy-saving and environmentally friendly. Various curved special-shaped columns can be formed into a rectangular profile by arranging a plurality of conversion reinforcement ribs on the outside of the curved special-shaped polymer formwork, thereby reducing the difficulty of support reinforcement, facilitating the construction of various conventional support components, giving full play to the strength of the support components, and improving the reliability of the overall formwork system.

[0019] The present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0020] Example 1

[0021] Combine Figure 1-Figure 3 As shown, a 3D printing formwork system for curved special-shaped columns in this embodiment includes a enclosure component and a support component. The enclosure component is composed of four curved special-shaped polymer templates 1 and a plurality of conversion reinforcement ribs 2. The four curved special-shaped polymer templates 1 enclose the cross-sectional profile of the curved special-shaped column to be cast. The conversion reinforcement ribs 2 connected to the outside of the curved special-shaped polymer template 1 convert the cross-section of the curved special-shaped column into an ordinary rectangular cross-section. The conversion reinforcement ribs 2 and the curved special-shaped polymer template 1 are printed in an integrated manner and are evenly distributed on the outside of the curved special-shaped polymer template 1 with a spacing of 100mm-200mm. The support component is a square and round buckle 3 for fixing the enclosure component.

[0022] The specific installation steps are as follows:

[0023] Step 1: Based on the contour of the curved special-shaped column to be cast, the shape and size of the internal enclosure components and the shape and size of the conversion reinforcement rib 2 that forms the minimum rectangular cross-section are obtained through 3D printing design software;

[0024] Step 2: derive the strength and spacing of the conversion reinforcement rib 2 based on the simulation structure analysis;

[0025] Step 3: Print the required segmented curved surface special-shaped polymer template 1 using 3D printing technology;

[0026] Step 4: transport the printed curved special-shaped polymer template 1 to the site for assembly to form a curved special-shaped column enclosure component to be cast;

[0027] Step 5: Install the square and round buckles 3 and fasten them with fixing pins to form the required curved special-shaped column formwork system. The square and round buckles 3 can adopt the existing structure.

[0028] This project overcomes the difficulties of assembling and reinforcing the traditional wooden formwork system for curved and special-shaped columns, as well as the construction difficulties, impact on construction progress and relatively high costs brought about by the use of aluminum and steel formwork systems. Through 3D design software and the plasticity of 3D materials, the formwork is designed to be "curved inside and square outside". The inside of the formwork precisely fits the curved and special-shaped columns, and the outside of the formwork converts the curved surface into a rectangle, converting the reinforcement of the curved and special-shaped columns into the reinforcement of ordinary rectangular columns. This solves the difficulties in implementing the traditional formwork system for curved and special-shaped columns. At the same time, the 3D printed formwork is lightweight and can be manually transported and assembled. The forming effect is comparable to that of plain concrete, which improves the construction efficiency and final forming quality of the curved and special-shaped column formwork.

[0029] Example 2

[0030] like Figure 4 As shown, this embodiment is a 3D printing formwork support system for curved special-shaped columns, and its structure is roughly the same as that of Example 1, except that the curved special-shaped columns to be cast are elliptical columns.

[0031] Example 3

[0032] like Figure 5-Figure 6 As shown, this embodiment is a 3D printing formwork support system for curved special-shaped columns, and its structure is roughly the same as that of Example 2. The difference from Example 2 is that the curved special-shaped columns to be cast are elliptical variable-section columns.

All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be pointed out that for those skilled in the art, various improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
