Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of special-shaped structure template preparation, and particularly relates to a composite special-shaped permanent template, a preparation method thereof and a special-shaped composite concrete combined structure. BACKGROUND

[0002] Template engineering is one of the key links in the construction process of concrete structures and combined structures, and has a significant impact on the quality, safety, progress and economic benefits of construction projects. At present, the types of special-shaped concrete structure templates commonly used in engineering can be divided into wood templates, metal templates (steel and aluminum) and polymer templates according to the materials. Among them, the glued wood template is the most widely used template type in concrete construction, but it is only suitable for making simple curved surface special-shaped concrete structures, and basically cannot be reused, and is difficult to recycle after being discarded, which easily pollutes the environment. Steel templates and aluminum alloy templates are produced by bending, cutting and welding of metal plates in the factory or on site, and can be used for pouring special-shaped concrete structures, with high size accuracy. However, the metal template is heavy in weight and needs a crane to complete loading and unloading and transportation. In addition, there are many joint gaps, which leads to a decrease in the flatness of the concrete surface. In addition, the production of special-shaped metal templates is difficult and costly. Polymer templates are mainly processed by hot forming combined with numerical control line cutting. Commonly used materials include polypropylene (PP), polyethylene (PE), polyvinyl chloride (PVC) and polylactic acid (PLA). Polymer templates can be used for a large number of cycles, have low template cost and strong designability. However, the rigidity and strength of pure polymer templates are low, and they are easily affected by steel bar welding. At present, the market share is only about 10%.

[0003] Composite material templates are a kind of templates with good mechanical properties by adding dispersed or continuous fibers in a polymer matrix. The composite material templates used in engineering at present are divided into two types: one is entirely made of composite materials; and the other is composed of composite material panels and supporting structures. Compared with traditional templates, composite material templates have the advantages of good mechanical properties and durability, light weight, convenience for transportation and construction, etc. However, the traditional manufacturing process of composite material templates (including resin transfer molding technology, molding, extrusion molding, etc.) is relatively complex, and requires corresponding molds and special equipment, which increases the manufacturing cost. Although composite material templates have high engineering application value, if the components or nodes in the concrete structure or combined structure are irregular shapes (special-shaped), the production difficulty and cost of the templates will be significantly increased.

[0004] Therefore, the existing composite material template technology needs to be further improved and promoted, and in particular, the invention and innovation should be carried out for the problems in the production of composite special-shaped permanent templates and their concrete structures.

[0036] Figure 3 This is a cross-sectional schematic diagram of an irregularly shaped composite concrete structure provided by the present invention. Detailed Implementation

[0037] This invention provides a method for manufacturing irregularly shaped permanent formwork made of composite materials and an irregularly shaped composite material concrete composite structure. To make the objectives, technical solutions, and effects of this invention clearer and more explicit, the invention is further described in detail below. It should be understood that the specific embodiments described herein are only for explaining the invention and are not intended to limit the invention.

[0038] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments. Simultaneously, the steps or actions in the method description can be rearranged or adjusted in a manner readily apparent to those skilled in the art. Therefore, the various orders in the specification and drawings are merely for the clear description of a particular embodiment and do not imply a mandatory order, unless otherwise stated that a particular order must be followed. The component designations used herein, such as "first," "second," etc., are merely for distinguishing the described objects and do not have any sequential or technical meaning.

[0039] like Figure 1 As shown, the present invention provides a method for manufacturing a composite material irregular-shaped permanent template, comprising the following steps:

[0040] S1, according to the design requirements of the composite special-shaped permanent formwork, a three-dimensional model of the special-shaped concrete composite structure to be built is established; the design requirements include appearance, structure, bearing capacity and durability.

[0041] Specifically, before the formwork is made, a special-shaped composite concrete composite structure model is established according to the preset parameters. The model establishment can preliminarily design the shape, size, fiber arrangement, etc. of the core mold and the winding layer according to the design requirements of the appearance, structure, bearing capacity, durability, etc. of the composite structure to be made, determine the material parameters of concrete, winding fiber and formwork, input load and boundary conditions, and check the strength and rigidity of the composite structure. Among them, the verification of the mechanical performance indicators of the component or node can also complete the modeling and analysis by means of finite element analysis, such as calculating the internal force, stress, strain, displacement and other indicators, checking the strength and rigidity of the structure. By checking the strength and rigidity of the structure in advance, the requirements of the structure forming capacity, mechanical properties, durability, etc. can be better guaranteed. Because the special-shaped permanent formwork has certain particularity, which is specifically reflected in: irregular shape; large size (500~2000 mm); the polymer core mold needs to have sufficient strength and rigidity to ensure that it will not deform greatly during winding; since the composite special-shaped permanent formwork is used as a permanent formwork, it needs to have certain mechanical properties (i.e. strength and rigidity), provide certain restraint force to the internal concrete, and can bear certain axial load and bending load; has durability requirements to avoid corrosion caused by atmospheric, marine environment, etc.; there may be connections between the block formworks or between the composite structures. It should be noted that the model involved in the three-dimensional modeling and the specific construction process of the model belong to the known technology in the art, what is expressed here is to analyze the stress condition of the designed formwork by means of the constructed three-dimensional model, and optimize the material and process parameters involved in the construction of the formwork according to the stress condition.

[0042] S2, the three-dimensional model is calculated to obtain the internal force distribution result, based on the internal force distribution result, the 3D printing parameters of the special-shaped polymer core mold are optimized respectively to obtain the optimized 3D printing parameters; the winding parameters of the winding layer are optimized to obtain the optimized winding parameters.

[0043] Specifically, the three-dimensional model can be analyzed by means of finite element analysis to calculate indicators such as stress, strain, displacement, and to optimize the 3D printing of the polymer core mold and the winding layer winding setting target, such as setting the stress and strain distribution of the polymer core mold and the winding layer, the deformation of the structure and other quantifiable indicators, which are used to better control the quality of the subsequent printed core mold, such as judging whether the printed core mold or the wound fiber in the subsequent step meets the optimization target. If the optimization target is not met, the material category, control parameter, structure geometric size and other variables should be adjusted, and the process is repeated until the optimization target is met. In other words, the method provided by the present application includes an optimization step, and through continuous iteration and optimization, the printed and wound composite material special-shaped permanent mold can have higher performance. It should be noted that the internal force in the text refers to the force borne by the special-shaped concrete composite structure to be built. The force borne by different shapes and positions is different. By analyzing the internal force bearing condition, targeted measures can be taken.

[0044] S3, according to the optimized 3D printing parameters, using 3D printing to make the special-shaped polymer core mold; according to the optimized winding parameters, using a winding device to prepare a winding layer on the surface of the polymer core mold to obtain the composite material special-shaped permanent mold.

[0045] Specifically, according to the optimization result, the corresponding 3D printing polymer material type and 3D printing parameters are selected. The materials commonly used for printing polymer core mold include but are not limited to commonly used 3D printing materials such as PLA, ABS, ASA, etc. The 3D printing parameters include the temperature of the nozzle, the moving speed, the path, the material filling rate, etc.

[0046] The special-shaped polymer core mold can be made by using a 3D printer based on FDM (Fused Deposition Modeling) or FGF (Fused Granular Fabrication) technology. According to the purpose and structural requirements of the special-shaped concrete composite structure to be built, the material with corresponding performance is selected to make the core mold. During the preparation of the core mold, the processing parameters such as nozzle temperature, hot bed temperature, printer spindle moving speed, workpiece filling rate, filling mode and attachment method should be recorded in detail. If the actual printed core mold does not meet the optimization target set in the above steps, the printing material, structure geometric size and printing parameter should be modified until the printed core mold meets the design requirements. The core mold should be as thin as possible but should meet the rigidity and strength requirements of winding. The core mold can also be in a hollow form as a skeleton required for winding. The core mold can be printed with horizontal and vertical stiffening ribs to improve the rigidity of the core mold and enhance the bonding performance between the core mold and the inner filled concrete.

[0047] Specifically, the fiber winding path and thickness are determined according to the optimized winding layer parameters, a fiber impregnated with resin (for example, epoxy or vinyl resin) is wound on the surface of the polymer core mold by using a winding device, and the composite special-shaped permanent mold is obtained.

[0048] Taking the winding material as the fiber as an example, a CAD / CAM system can be used to simulate the winding path, considering the influencing factors such as surface friction, winding angle, winding speed and spatial position of the winding fiber port, and outputting the rotation speed of the winding machine and the movement trajectory of the fiber outlet. The fiber winding device (such as an industrial winding machine) or an intelligent winding device (such as a mechanical arm or a multi-axis robot) is used to wind the core mold surface according to the simulation results, so as to ensure that the fiber speed is stable and the winding path is attached to the core mold surface according to the expected path. The fiber winding material can be glass fiber, basalt fiber, aramid fiber or carbon fiber, which should be selected according to the purpose and structure requirements of the structure. During the fiber winding process, the key parameters related to the winding angle, thickness, speed and path planning should be recorded in detail. If the winding result does not meet the optimization target set in the above steps, the material, winding parameters and structure geometry should be modified and returned for re-computation and analysis until the wound winding layer meets the design requirements. It is easy to understand that the winding material can be a single fiber material or a mixed multi-fiber material.

[0049] That is, the fiber winding technology of the present application is based on the results of the structural mechanics analysis model. First, a mechanical analysis model of the special-shaped composite concrete composite structure is established (a more accurate and complex three-dimensional finite element model can also be established), the fiber angle, thickness and density to be wound in each region are determined through the internal force, stress and strain distribution of the structure, and the fiber winding path program is formed. If the winding path does not meet the optimization target of the structure, the structural mechanics analysis model (or the finite element model) is modified, and the winding model is iteratively updated until the optimization target is met. Finally, the fiber winding device winds the polymer core mold which has been 3D printed according to the winding path program. It should be noted that, in theory, iteration of the core mold and the winding layer is not a necessary step, but due to errors in the actual processing (including 3D printing and fiber winding), and based on the goal of further reducing material consumption and reducing cost, optimization iteration is needed.

[0050] Based on the same inventive concept, the present application provides a composite special-shaped permanent mold prepared by the above preparation method.

[0051] Based on the same inventive concept, the present application provides a special-shaped composite concrete composite structure, such as Figure 3As shown, the profiled composite concrete composite structure comprises a profiled composite permanent formwork (3D printed core form and fiber winding layer), concrete filled in the formwork, and steel bars or composite reinforcing bars arranged at required positions.

[0052] Specifically, in combination with Figures 2 to 3 After the profiled composite permanent formwork is prepared, the concrete is poured into the completed fiber-wound permanent formwork, and curing is carried out according to the requirements of the specification. After the components or nodes of the profiled composite structure are cured, test or assembly and installation of the engineering structure can be carried out (since the composite formwork can be used permanently, the demolding process can be omitted). Before the concrete is poured into the profiled composite permanent formwork, reinforcing bars (steel bars, composite bars, etc.) or other reinforcing materials can be pre-arranged to improve the tensile bearing capacity of the structure. Since the winding fibers can provide a certain tensile bearing capacity for the structure, a small amount of reinforcing bars or no reinforcing bars can be arranged inside the concrete. The profiled composite permanent formwork and the concrete can be formed at one time, or can be assembled using a block connection technology. It has very high operation flexibility.

[0053] In summary, the present application uses 3D printed polymers to make profiled core forms, and uses fiber continuous winding technology to make profiled composite permanent formworks. The use of 3D printed polymers and winding technology to customize the production of complex-shaped composite structure components or node formworks solves the problems of difficult forming, easy deformation, low manufacturing precision and high cost of profiled permanent formworks, and reduces the cost and time required for designing and producing formworks. The present application can also be extended to develop manufacturing technology and equipment for continuous winding according to the characteristics of the profiled composite permanent formwork; according to the stress characteristics of the profiled permanent formwork during the concrete pouring and service stages, combined with manufacturing technology, interface mechanics analysis, finite element simulation, etc. to establish a new winding technology for profiled permanent formworks. The present application uses continuous winding technology to wind fibers impregnated with resin (such as epoxy and vinyl resin) on the profiled core form, ensuring that the continuous fibers can efficiently and uniformly cover the core form. The formed composite formwork can provide stable constraints and protection for the filled concrete, and improve the bearing capacity and durability of the concrete composite structure.

[0054] It should be understood that the application of the present application is not limited to the above examples, and those of ordinary skill in the art can make improvements or changes according to the above description, and all such improvements and changes shall fall within the scope of protection of the appended claims of the present application.
