[0028] In order to make the above-mentioned purposes, features and advantages of the application more obvious and easy to understand, the specific embodiments of the application will be described in detail below with reference to the drawings.

[0029] Please refer to Figure 4 The intersection line of the intersecting cylinders is located by the measurement positioning technology, and the positions of various special points of the intersection line are found out, the positions of the various special points are drawn on the finished cylinder by the field measurement personnel, and the cutting is manually performed by the construction personnel. This method has the problem of too large positioning error of the intersection line of the intersecting cylinders, which leads to large gap in template splicing and poor forming effect.

[0030] After verification: the traditional template cutting and assembling process cannot guarantee the processing accuracy, and the position of the intersection line of the cylinder interface cannot be completely guaranteed to be accurately positioned.

[0031] To solve the above technical problems, please refer to Figure 1 The embodiment of the application provides a special-shaped pipeline template manufacturing and installation method based on a BIM model, which comprises the following steps:

[0032] S 100 : establishing a three-dimensional entity model of a special-shaped pipeline and generating a three-dimensional template model of the special-shaped pipeline, wherein the special-shaped pipeline is formed by intersection and combination of several branch cylindrical pipelines.

[0034] S 300 : expanding the several three-dimensional component templates from a three-dimensional state to a two-dimensional state of template drawings in a BIM software;

[0035] S 400 : printing the two-dimensional state of template drawings on a spray cloth by using a 3D printer to obtain actual component templates of the special-shaped pipeline;

[0036] S 500 : attaching the actual component templates formed by the spray cloth to corresponding outer surfaces of the several branch cylindrical pipelines and cutting the branch cylindrical pipelines along the contour lines of the actual component templates to form each branch pipeline of the special-shaped pipeline;

[0037] S 600 : splicing and installing each branch pipeline to obtain an actual special-shaped pipeline.

[0038] For the template splicing process of the intersection of multiple cylindrical bodies in a spiral curved surface structure, the embodiment of the present application can replace the traditional measurement positioning template processing process, improve the operation efficiency, and avoid the problems of material waste and low splicing precision caused by the traditional template processing.

[0039] It should be noted that BIM (Building Information Modeling), also known as building information model, is a new type of computer application technology in the engineering construction industry. Through the design and use of various relevant information data of building engineering projects as the basis of the model, the information is shared and transmitted in the whole life cycle process of the planning, design, construction and operation management stages of the construction project, so that engineering and technical personnel can correctly understand and efficiently respond to various building information, and provide a basis for collaborative work for design teams, construction units and various construction subjects including building operation units, and play an important role in improving production efficiency, saving cost and shortening construction period. The BIM technology is introduced in the design stage, and a design application is developed for the speciality of the project.

[0040] Please refer to Figure 2 , 3 , and specifically to the embodiment of the present application, in step S100 In this context, generating the three-dimensional template model of the irregularly shaped pipe specifically includes:

[0041] The 3D solid model of the irregular pipe is simulated and thickened to a certain thickness h.

[0042] Extract the thickened 3D template model.

[0043] In this embodiment, a relevant component template model is established within the 3D model of the irregularly shaped pipe. Specifically, the outer surface of the irregularly shaped pipe is extended by 20mm (the actual template thickness), and the component template model is extracted. Thus, to obtain a surface template of the true size of the irregularly shaped pipe, computer-aided software is used to thicken the 3D model, resulting in an accurate 3D template model.

[0044] Please see Figure 2 As shown, specifically in the embodiments of the present invention, in step S 200 In this context, the virtual cutting of the three-dimensional template model to form several actual component templates specifically includes:

[0045] The three-dimensional template model is selected using BIM software;

[0046] Based on the intersection lines, cross lines, and boundary lines of the three-dimensional template model, the surface of the three-dimensional template model is divided into a grid to form multiple template panels;

[0047] Based on the thickness of the three-dimensional template model, the multiple template panels are cut appropriately;

[0048] The three-dimensional template model is divided into blocks and numbered to form several actual component templates.

[0049] Therefore, considering the characteristics of irregularly shaped pipes, BIM technology is applied to the formwork manufacturing and installation process of irregularly shaped pipes. By using BIM technology to establish a three-dimensional model of the irregularly shaped pipe formwork, virtual cutting and assembly are further carried out to obtain the physical drawing of the component formwork.

[0050] Specifically, in the embodiments of the present invention, in step S 400 In this process, the two-dimensional template drawing is printed on the inkjet cloth using a 3D printer at a scale of 1:1.

[0051] After the intersecting line drawings of each component are exported by using the Dassault 3DE platform, the 1:1 printing of the drawings is carried out through the corresponding component drawings, the printed 1:1 drawings are attached to the surface of the branch cylindrical pipeline, and the construction personnel can directly cut the branch cylindrical pipeline according to the corresponding component template arc, and the cut branch cylindrical pipeline is the finished product and can be directly assembled on the construction site.

[0052] Specifically, in step S 100 , the method for establishing the three-dimensional entity model of the special-shaped pipeline is to use the Dassault 3DE platform.

[0053] Through the modeling of the digital software 3DE XPERIENCE platform, the model accuracy can be improved to LOD400, and the node model is generated, then the intersecting line drawings are generated by using the model, finally the spray cloth cutting template is used for splicing on the construction site, which reduces the technical difficulty of template processing, is easy to understand for the construction personnel, and is simple to operate.

[0054] Specifically, in step S 500 , the shape of each branch pipeline is a cylindrical structure.

[0055] Since the quality of the concrete pouring molding is good, the concrete at the intersection of each branch pipeline is smooth and smooth without honeycomb and pitted surface phenomenon, therefore, the special-shaped pipeline in the embodiment is poured and molded by concrete, and the pipeline with the cylindrical structure is convenient for construction and can be assembled to form various special-shaped pipelines.

[0056] Although the present application is disclosed as above, the protection scope of the present application is not limited to this. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present application, and these changes and modifications will fall within the protection scope of the present application.
