[0034] The present invention will be described in detail below with reference to the accompanying drawings: According to the following description, the advantages and features of the present invention will be clearer. It should be noted that the accompanying drawings are all in a very simplified form and use non-precise scales, only for the purpose of conveniently and clearly assisting in explaining the purpose of the embodiments of the present invention.

[0035] Please refer to Figures 1 to 4 and Figure 8, an embodiment of the present invention provides a mold for a historical building component with different internal and external structural materials, including a central sleeve 300, an inner mold assembly 100, and an outer mold assembly 200 that are sequentially nested at intervals from the inside to the outside. The inner mold assembly 100 includes an inner mold 110 located outside the central sleeve 300 and matching the outer contour shape of the internal structural layer 410 of the historical building component 400, that is, the inner mold 110 has a cavity matching the outer contour shape of the internal structural layer 410 of the historical building component 400, a first support rod 120 inserted and connected in the central sleeve 300, and an inner mold support frame 130 detachably connected between the first support rod 120 and the inner mold 110. There are two inner mold support frames 130, respectively located at both ends of the inner mold 110; the outer mold assembly 200 includes an outer mold 210 located outside the inner mold 110 and matching the outer contour shape of the external structural layer 420 of the historical building component 400, that is, the outer mold 210 has a cavity 211 matching the outer contour shape of the external structural layer 420 of the historical building component 400, a second support rod 220 inserted and connected in the central sleeve 300, and an outer mold support frame 230 detachably connected between the second support rod 220 and the outer mold 210. There are two outer mold support frames 230, respectively located at both ends of the outer mold 210; the first support rod 120 and the second support rod 220 are common parts or independent parts.

[0036] Please refer to Figures 2 to 3 , in order to improve the stability of the inner mold 110 during use and improve the construction quality of the structural shape of the internal structural layer 410 of the historical building component 400, for the mold of the historical building component with different internal and external structural materials provided by the embodiment of the present invention, both the inner mold support frame 130 and the outer mold support frame 230 are hollow skeletons. The hollow skeleton can be an inner ring member, an outer ring member, and multiple rod-shaped members evenly distributed radially between the two. The inner ring member can be detachably connected to the first support rod 120 or the second support rod 220 by a threaded connection, a snap connection, etc. The outer ring member and the inner mold 110 or the outer mold 210 can be detachably connected by a snap connection, etc. Thus, the inner mold 110 and the outer mold 210 are respectively supported by the inner mold support frame 130 and the outer mold support frame 230 at the upper and lower ends, preventing displacement and affecting the molding quality of the mold.

[0037] Of course, in order to fix the inner mold 110, for the mold of the historical building component with different internal and external structural materials provided by the embodiment of the present invention, one end of the inner mold support frame 130 can be a hollow skeleton, and the other end of the inner mold support frame 130 can be a plate-shaped member. At the same time, one end of the outer mold support frame 230 can also be a hollow skeleton, and the other end of the outer mold support frame 230 can also be a plate-shaped member. During use, place the support frame of the plate-shaped member on a plane.

[0038] The embodiment of the present invention further provides a manufacturing method for a historical building component 400 with different internal and external structure materials. By using the above-mentioned mold for a historical building component with different internal and external structure materials, it may include:

[0039] Step S1, please refer to Figure 4 and Figure 8 , use a 3D printer to respectively obtain the outer contour shape information of the internal structure layer 410 and the external structure layer 420 of the historical building component 400 according to the three-dimensional laser scanning technology for 3D printing to manufacture the inner mold 110 and the outer mold 210, so that the cavities of the inner mold 110 and the outer mold 210 respectively match the outer contour shapes of the internal and external structure layers 420 of the historical building component 400. The inner mold 110 and the outer mold 210 are 3D printed by a 3D printer according to the outer contour shape information of the internal structure layer 410 and the external structure layer 420 of the real historical building component 400, which can improve the consistency of the cavities of the inner mold 110 and the outer mold 210 respectively matching the outer contour shapes of the internal structure layer 410 and the external structure layer 420 of the historical building component 400. Thus, a high-quality internal structure layer 410 is manufactured through the inner mold 110, and a high-quality external structure layer 420 is manufactured around the internal structure layer 410 through the outer mold 210, forming a high-quality and high-precision historical building component 400. Please refer to Figures 4 to 5 , when the historical building component with different internal and external structure materials manufactured by the mold is a double-layer columnar member, the cavities of the inner mold 110 and the cavity 211 of the outer mold 210 are both columnar, and thus a columnar body with a double-layer structure is manufactured through the mold. Please refer to Figures 8 to 9 , when the historical building component with different internal and external structure materials manufactured by the mold is a vase-shaped railing, the cavities of the inner mold 110 and the cavity 211 of the outer mold 210 are both in the shape of a vase-shaped railing, and thus a double-layer structure vase-shaped railing is manufactured through the above-mentioned mold. By using the 3D printing technology to form the above-mentioned mold with high precision that is consistent with the outer contour shapes of the internal structure layer 410 and the external structure layer 420 of the historical building component 400, it avoids the problems such as low work efficiency, difficult quality guarantee, and high dependence on the skills of workers and masters brought about by the traditional process of dividing complex shapes into multiple small modules for manufacturing.

[0040] Step S2, please refer to Figure 2 、 Figures 4 to 5, arrange the inner mold assembly 100 vertically on a plane, arrange the central sleeve 300 at the vertical center of the inner mold 110 of the inner mold assembly 100, insert the first support rod 120 of the inner mold assembly 100 into the central sleeve 300, and install inner mold support frames 130 between the inner mold 110 at the upper and lower ends and the corresponding first support rods 120 at the upper and lower ends to support both ends of the inner mold 110. Pour inner layer slurry into the gap between the central sleeve 300 and the inner mold 110 to form the internal structure layer 410 of the historical building component 400, so that the outer contour shape of the internal structure layer 410 of the historical building component 400 is consistent with the cavity of the inner mold 110. The inner layer slurry can be concrete.

[0041] Step S3, after the inner layer slurry of the internal structure layer 410 of the historical building component 400 reaches the strength condition, retain the central sleeve 300 and remove the inner mold assembly 100.

[0042] Step S4, please refer to Figure 3 , apply a retarder to the cavity of the outer mold 210 of the outer mold assembly 200, sleeve the outer mold assembly 200 around the periphery of the internal structure layer 410 of the historical building component 400, insert the second support rod 220 of the outer mold assembly 200 into the central sleeve 300, and install outer mold support frames 230 between the outer mold 210 at the upper and lower ends and the corresponding second support rods 220 at the upper and lower ends to support both ends of the outer mold 210. Pour outer layer slurry into the gap between the internal structure layer 410 of the historical building component 400 and the outer mold 210 to form the external structure layer 420 of the historical building component 400, so that the external structure layer 420 adheres to the internal structure layer 410, and the outer contour shape of the external structure layer 420 of the historical building component 400 is consistent with the cavity 211 of the outer mold 210. The outer layer slurry can be pebble dash.

[0043] Step 51, please refer to Figures 4 to 5 , after the outer layer slurry of the external structure layer 420 of the historical building component 400 reaches the strength condition, retain the central sleeve 300 and remove the outer mold assembly 200.

[0044] Step S6, please refer to Figure 6 , densely fill the inner layer slurry in the central sleeve 300 to form the historical building component 400 with a solid structure, realizing the restoration construction of the historical building component 400. Self-leveling slurry can be used for filling to improve its density.

[0045] The mold and manufacturing method for historical building components with different internal and external structure materials provided by the embodiments of the present invention, when constructing historical building components 400 with different internal and external structure materials such as columnar bodies and vase railings with double-layer structures, by fixedly installing the inner mold assembly 100 on the central sleeve 300, making the inner mold assembly 100 located on the periphery of the central sleeve 300, pouring inner layer slurry into the gap between the central sleeve 300 and the inner mold 110 to form the internal structure layer 410 of the historical building component 400, making the outer contour shape of the internal structure layer 410 of the historical building component 400 consistent with the cavity of the inner mold 110, thereby improving the construction quality and construction accuracy of the outer contour shape of the internal structure layer 410 of the historical building component 400 made of the inner layer slurry; by sleeving the outer mold assembly 200 on the periphery of the internal structure layer 410 of the already constructed historical building component 400 and installing it on the central sleeve 300, pouring outer layer slurry into the gap between the outer mold 210 and the internal structure layer 410 to form the external structure layer 420 of the historical building component 400, making the outer contour shape of the external structure layer 420 of the historical building component 400 consistent with the cavity of the outer mold 210, thereby improving the construction quality and accuracy of the outer contour shape of the external structure layer 420 of the historical building component 400 made of the outer layer slurry, and by bonding the external structure layer 420 to the internal structure layer 410, thereby improving the connection quality between the internal and external structure layers, avoiding the problem of their detachment, and further improving the overall construction quality of historical building components 400 with different internal and external structure materials such as vase railings and column railings, and performing high-quality restoration construction on the historical building component 400. Compared with the method of manufacturing historical building components 400 with different internal and external structure materials using the small formwork splicing construction process, it has the advantages of high restoration quality, high manufacturing efficiency, and little influence by the skill level of craftsmen.

[0046] Please refer to Figure 7 , in order to improve the structural strength of the manufactured historical building component 400, in the manufacturing method for historical building components with different internal and external structure materials provided by the embodiments of the present invention, in step S6, component steel bars 411 can be inserted into the central sleeve 300, and the inner layer slurry can be densely filled into the gap between the component steel bars 411 and the central sleeve 300 to form a solid-structured historical building component 400, realizing the restoration construction of the historical building component 400.

[0047] In order to stably bond the fabricated outer structural layer 420 to the inner structural layer 410, the present invention provides a mold and manufacturing method for historical building components with different internal and external structural materials. The cavity of the inner mold 110 that matches the outer contour shape of the inner structural layer 410 of the historical building component 400 is an uneven surface. The inner mold 110 is fabricated by 3D printing based on the outer contour shape information of the inner structural layer of the historical building component 400 obtained by 3D laser scanning technology and adding uneven surface information, so that the cavity of the inner mold 110 matches the outer contour shape of the inner structural layer of the historical building component 400 and has an added uneven surface shape. Through the design of the cavity of the inner mold 110 being an uneven surface, the roughness of its outer contour is increased, so that the outer structural layer 420 can be reliably and stably bonded to the inner structural layer 410, improving the connection quality between the structures of the historical building component 400.

Especially for the production of patterns and decorative patterns on the outer contour shape of the outer structural layer 420, it will be more accurate, avoiding problems such as the need to improve the restoration efficiency and the difficulty in ensuring the repair quality faced by traditional repair techniques due to the break of craftsmen and the loss of techniques. It can be widely applied to engineering projects for restoring large-scale historical features. And during the entire implementation process, it can be highly industrialized. It can be prefabricated or constructed on-site. The mold can be reused repeatedly, having the advantages of green construction, energy conservation and environmental protection.
