[0031] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0032] Reference below Figure 1-Figure 4 A casting mold 100 for a prefabricated tower according to an embodiment of the present invention is described.

[0033] like Figure 1As shown, according to the casting mold 100 of the prefabricated tower according to an embodiment of the present invention, the casting mold 100 defines a plurality of casting cavities 3 which are sequentially arranged along the radial direction, wherein the plurality here refers to two or more, and concrete can be poured into the casting cavity 3 to produce a tower section or a tower segment. By arranging a plurality of casting cavities 3 in the casting mold 100, a plurality of tower sections or tower segments can be cast in the casting mold 100 at the same time, and the construction efficiency is high.

[0034] Specifically, the casting mold 100 includes a base mold 1, multiple inner mold plates 21, multiple outer mold plates 22 and a bellows fixing plate 4. The projection of each inner mold plate 21 in the vertical plane is cylindrical or conical, and the projection in the horizontal plane is arc-shaped or circular. The multiple inner mold plates 21 are arranged in sequence along the radial direction. The projection of each outer mold plate 22 in the vertical plane is cylindrical or conical, and the projection in the horizontal plane is arc-shaped or circular. The multiple outer mold plates 22 are arranged in sequence along the radial direction. The multiple outer mold plates 22 and the multiple inner mold plates 21 are staggered in the radial direction to define a plurality of casting cavities 3 arranged in sequence along the radial direction. The inner wall of each casting cavity 3 is constructed by the inner mold plate 21, and the outer wall of each casting cavity 3 is constructed by the outer mold plate 22.

[0035] The horizontal plane here refers to a plane parallel to the plane where the bottom mold 1 is located, and the vertical plane refers to a plane perpendicular to the horizontal plane. Cylindrical means that the diameters of the inner mold plate 21 or the outer mold plate 22 in the vertical direction are the same, and conical means that the diameters of the inner mold plate 21 or the outer mold plate 22 in the vertical direction are different. Therefore, it can be understood that the cylindrical inner mold plate 21 or the outer mold plate 22 and the conical inner mold plate 21 or the outer mold plate 22 can be matched in different forms according to needs to produce tower sections or tower segments of different models.

[0036] Further, the projection of the arc-shaped inner template 21 or outer template 22 in the horizontal plane can be an arc, and the arc can be composed of a semicircle or a quarter circle. Of course, it can be understood that the arc can also have other angles, which are not limited here. In some examples, the inner template 21 and the outer template 22 composed of a semicircle or a quarter circle can be matched with the bottom mold 1 to produce a tower segment, multiple tower segments can be matched to form a tower barrel segment, and multiple tower barrel segments can form a tower barrel.

[0037] Furthermore, the arc-shaped inner template 21 or outer template 22 can also be combined into a circular inner template 21 or outer template 22 according to needs. By cooperating with the circular inner template 21 and the circular outer template 22, the tower section can be directly produced. Of course, it can be understood that the inner template 21 or the outer template 22 can also be circular. There is no restriction on the structural form and combination method of the inner template 21 and the outer template 22, and it can be specifically set according to actual production needs.

[0038] In such Figure 1 and Figure 2 In a specific example shown, the casting mold 100 is formed into a cylindrical shape. In the radial direction of the casting mold 100, two casting cavities 3 are provided. The two casting cavities 3 are spaced apart, and each casting cavity 3 is defined by an inner template 21, an outer template 22 and a bottom template 1. For the convenience of explanation, the outer casting cavity 3 is referred to as the first casting cavity 31, and the first casting cavity 31 includes the first inner template 21 and the first outer template 22. The inner casting cavity 3 is referred to as the second casting cavity 32, and the second casting cavity 32 includes the second inner template 21 and the second outer template 22. Specifically, the second outer template 22 is sleeved on the outside of the second inner template 21, the first inner template 21 is sleeved on the outside of the second outer template 22, and the first outer template 22 is sleeved on the outside of the first outer template 22. Of course, it is understandable that the casting mold 100 may also be provided with multiple casting cavities 3 such as a third casting cavity and a fourth casting cavity, wherein the inner template 21 of each casting cavity 3 is sequentially sleeved on the outside of the outer template 22 of the previous casting cavity 3, and the outer template 22 of each casting cavity 3 is sleeved on the outside of the inner template 21 of the casting cavity 3 to which it belongs, and there is no limitation here.

[0039] Of course, it is understandable that the inner template 21 and the outer template 22 can also be formed into a conical barrel shape, or the outer template 22 is formed into a cylindrical shape and the inner template 21 is formed into a conical barrel shape, or the outer template 22 is formed into a conical barrel shape and the inner template 21 is formed into a cylindrical shape. The shapes of the inner template 21 and the outer template 22 can be set according to actual application requirements and are not limited here.

[0040] Furthermore, the first casting cavity 31 and the second casting cavity 32 can both be formed by the inner formwork 21 and the outer formwork 22, thereby reducing the interference between the first casting cavity 31 and the second casting cavity 32, which is conducive to building the tower in the first casting cavity 31 and the second casting cavity 32. At the same time, when the tower in the first casting cavity 31 and the second casting cavity 32 is demolded, the inner formwork 21 and the outer formwork 22 of the first casting cavity 31 and the second casting cavity 32 can be removed respectively, which can reduce the difficulty of demolding the tower, improve the demolding efficiency of the tower, and is not easy to damage the tower, with a good demolding effect.

[0041] Therefore, according to the casting mold 100 of the prefabricated tower according to the embodiment of the present invention, by setting multiple casting cavities 3 in the casting mold 100, multiple tower sections or tower segments can be built simultaneously in the casting mold 100, and the building efficiency is high. Furthermore, each casting cavity 3 is composed of an inner template 21 and an outer template 22, which can better cast the tower section or tower segment. At the same time, after the tower section or tower segment is solidified, the demolding efficiency and demolding effect of the tower section or tower segment can be improved.

[0042] It can be understood here that if the side wall of the casting cavity has no distinction between inner and outer templates, the same cylindrical plate is used to define both the outer circumferential wall of the inner casting cavity and the inner circumferential wall of the outer casting cavity. It is necessary not only to ensure the compressive strength of the concrete poured on both sides, but also to ensure the smoothness of both sides. The processing difficulty is very large, and it is difficult to adjust the thickness and coaxiality. In the embodiment of the present invention, the inner and outer circumferential walls of each casting cavity 3 are defined by independent inner templates 21 and outer templates 22. Each template only needs to ensure smoothness on one side, and it is easier to adjust the position of each template and the spacing between templates. Therefore, not only the processing difficulty is greatly reduced, but also the thickness and coaxiality can be adjusted conveniently. In addition, when a template is damaged, it is also easier and less costly to replace.

[0043] In some embodiments, the bellows fixing plate 4 is disposed at the top of the casting cavity 3, and the bellows fixing plate 4 is connected to the inner formwork 21 and the outer formwork 22 of the corresponding casting cavity 3, and a positioning hole 41 for positioning the bellows 42 is provided on the bellows fixing plate 4. It should be noted that when using concrete to build a tower section or a tower segment, it is necessary to pre-embed the bellows 42 inside the tower section or the tower segment to facilitate the installation of the tower section or the tower segment. The tower section or the tower segment is stretched by prestressed tendons to facilitate the stability of the tower section or the tower segment after installation. Specifically, the bellows fixing plate 4 has a positioning hole 41, and the positioning hole 41 can cooperate with the bellows 42 so that the bellows 42 is installed on the bellows fixing plate 4. Further, the bellows fixing plate 4 can be installed on the top of the casting cavity 3, that is, Figure 1 and Figure 2 As shown, one end of the bellows fixing plate 4 is installed and fixed on the upper end of the inner template 21, and the other end of the bellows fixing plate 4 is installed and fixed on the upper end of the outer template 22. Therefore, a positioning hole 41 is formed at the upper ends of the inner template 21 and the outer template 22, and is formed between the inner template 21 and the outer template 22. The cooperation between the bellows 42 and the positioning hole 41 can facilitate the positioning of the bellows 42 in the casting cavity 3, thereby facilitating the construction of the tower section or the tower segment.

[0044] In some embodiments, the bottom of the inner formwork 21 and the outer formwork 22 can be detachably connected to the base formwork 1, that is, the bottom of the inner formwork 21 can be installed on the base formwork 1, and the inner formwork 21 can be disassembled from the base formwork 1 after being installed on the base formwork 1, and the bottom of the outer formwork 22 can be installed on the base formwork 1, and the outer formwork 22 can be disassembled from the base formwork 1 after being installed on the base formwork 1, which can facilitate the demolding of the casting mold 100 and the recycling of the casting mold 100, thereby saving construction costs.

[0045] In some embodiments, between two radially adjacent casting cavities 3, the top of the inner template 21 and the top of the outer template 22 are overlapped or butt-jointed. Figure 1and Figure 2 As shown, between two radially adjacent casting cavities 3, the inner template 21 of the outer casting cavity 3 is sleeved on the outer side of the outer template 22 of the inner casting cavity 3, and the top of the inner template 21 of the outer casting cavity 3 overlaps the upper end of the top of the outer template 22 of the inner casting cavity 3, thereby, the inner template 21 of the outer casting cavity 3 and the bottom of the outer template 22 of the inner casting cavity 3 can be fixed on the bottom mold 1 by a first fixing device, and the inner template 21 of the outer casting cavity 3 overlaps the top of the outer template 22 of the inner casting cavity 3, which can be beneficial to fix the inner template 21 of the outer casting cavity 3 and the top of the outer template 22 of the inner casting cavity 3, so that the inner template 21 of the outer casting cavity 3 and the outer template 22 of the inner casting cavity 3 can limit each other, so as to be more firmly assembled on the bottom mold 1. Of course, it is understandable that the top of the outer formwork 22 of the inner casting cavity 3 can also overlap the top of the inner formwork 21 of the outer casting cavity 3, or the top of the inner formwork 21 of the outer casting cavity 3 can be connected to the top of the outer formwork 22 of the inner casting cavity 3, which is not limited here.

[0046] In some embodiments, on at least one side in the radial direction of the casting cavity 3, the bellows fixing plate 4 is connected to the overlapping inner template 21 and outer template 22. That is to say, the bellows fixing plate 4 can be set on one side in the radial direction of the casting cavity 3, and multiple bellows fixing plates 4 can also be set at other positions in the radial direction of the casting cavity 3, and multiple here refers to two or more. Among the multiple bellows fixing plates 4, each bellows fixing plate 4 can position the bellows 42, that is, multiple bellows 42 can be set in the radial direction of each tower section or tower segment, and further, each bellows fixing plate 4 is fixedly connected to the inner template 21 and the outer template 22 of the casting cavity 3 where the positioned bellows 42 is located.

[0047] Optionally, a conical hole 52 is formed on the corrugated tube fixing plate 4 and the overlapping inner template 21 and outer template 22, and a conical pin 51 is matched on the conical hole 52. Figure 1-Figure 4As shown, between two adjacent casting cavities 3, the top of the inner template 21 of the outer casting cavity 3 overlaps the top of the outer template 22 of the inner casting cavity 3, and a tapered hole 52 can be provided at the position where the inner template 21 of the outer casting cavity 3 overlaps the outer template 22 of the inner casting cavity 3. The bellows fixing plate 4 can be arranged at the upper end of the inner template 21 of the outer casting cavity 3, and a tapered hole 52 is provided at the corresponding position of the bellows fixing plate 4. The tapered pin 51 can pass through the bellows fixing plate 4, the outer template 21, and the inner template 22 of the inner casting cavity 3 in sequence from top to bottom. The tapered holes 52 of the inner template 21 of the casting cavity 3 and the outer template 22 of the inner casting cavity 3 fix the bellows fixing plate 4, the inner template 21 of the outer casting cavity 3 and the outer template 22 of the inner casting cavity 3, which is beneficial to the positioning and installation of the bellows fixing plate 4, and is also beneficial to the fixation between the inner template 21 of the outer casting cavity 3 and the outer template 22 of the inner casting cavity 3, which can reduce the number of tapered pins 51 on the casting mold 100 to save costs and improve the assembly efficiency of the casting mold 100.

[0048] In some embodiments, the top of each inner mold plate 21 is provided with an inner mold flange 211 extending horizontally along the radial outer side, and the top of each outer mold plate 22 is provided with an outer mold flange 221 extending horizontally along the radial inner side. The inner mold plate 21 and the outer mold plate 22 are overlapped by the inner mold flange 211 and the outer mold flange 221. For example, Figure 4 As shown, the inner mold flange 211 is formed at the top of the inner mold plate 21, and the inner mold flange 211 extends toward the outer mold plate 22, and the outer mold flange 221 is formed at the top of the outer mold plate 22, and the outer mold flange 221 extends toward the inner mold plate 21. As a result, the inner mold flange 211 and the outer mold flange 221 can be more easily abutted, which can be beneficial to improving the assembly efficiency between the inner mold plate 21 and the outer mold plate 22. At the same time, the tapered hole 52 can be easily processed on the inner mold flange 211 and the outer mold flange 221, which can reduce the processing difficulty of the tapered hole 52 and save processing costs.

[0049] Optionally, the top surfaces of all inner mold flanges 211 are flush, and the top surfaces of all outer mold flanges 221 are flush. Therefore, when the inner mold flanges 211 and outer mold flanges 221 of two adjacent casting cavities 3 cooperate, the top surfaces of the flush inner mold flanges 211 can be easily overlapped with the top surfaces of the flush outer mold flanges 221. At the same time, the inner mold flanges 211 and the outer mold flanges 221 can be relatively flat after overlapping, which can make the inner mold plate 21 and the outer mold plate 22 relatively flat after overlapping, so that the tower section or tower segment after casting is relatively flat, which can improve the construction effect of the tower section or tower segment.

[0050] In some embodiments, between two radially adjacent casting cavities 3, an inner mold extrusion is provided on the side wall of the inner mold plate 21 adjacent to the central axis, and an outer mold extrusion is provided on the side wall of the outer mold plate 22 away from the central axis. The outer mold extrusion and the inner mold extrusion are in radial extrusion contact with each other, wherein the central axis here can refer to the central axis of the cylindrical casting mold 100 as shown in the figure.

[0051] For example Figure 2 and Figure 4 As shown, between the two connected casting cavities 3, the side wall of the inner template 21 adjacent to the central axis is opposite to the side wall of the outer template 22 away from the central axis, thereby, an inner mold extrusion piece is arranged on the side wall of the inner template 21 adjacent to the central axis, and an outer mold extrusion piece is arranged on the side wall of the outer template 22 away from the central axis, and the inner mold extrusion piece and the outer mold extrusion piece can be extruded and contacted in the radial direction. When concrete is poured into the casting cavity 3, the extrusion force of the inner mold extrusion piece and the outer mold extrusion piece bracket can offset the force of the concrete on the side wall of the inner template 21 away from the central axis and the force of the concrete on the side wall of the outer template 22 close to the central axis, so that the inner template 21 and the outer template 22 are not easy to deform, thereby improving the structural strength of the inner template 21 and the outer template 22, and making the casting mold 100 more reliable.

[0052] Optionally, a plurality of inner mold annular ribs 212 and a plurality of inner mold longitudinal ribs 213 are provided on the side wall adjacent to the central axis of each inner mold plate 21, and the plurality of inner mold annular ribs 212 and the plurality of inner mold longitudinal ribs 213 are cross-connected, and a plurality of outer mold annular ribs 222 and a plurality of outer mold longitudinal ribs 223 are cross-connected on the side wall away from the central axis of each outer mold plate 22. Thus, by providing the inner mold annular ribs 212 and the inner mold longitudinal ribs 213 on the side wall of the inner mold plate 21, the structural strength of the inner mold plate 21 can be improved, and by providing the outer mold annular ribs 222 and the outer mold longitudinal ribs 223 on the side wall of the outer mold plate 22, the structural strength of the outer mold plate 22 can be improved. By improving the structural strength of the inner mold plate 21 and the outer mold plate 22, the structural strength of the casting mold 100 can be improved, so that the casting mold 100 is not easily damaged or deformed, and the tower section or tower segment can be built more reliably.

[0053] Optionally, between two radially adjacent casting cavities 3, a protrusion 2231 is provided on the outer mold longitudinal rib 223 to be pressed on the inner mold annular rib 212. Figure 3As shown, a protrusion 2231 is provided on the outer mold longitudinal rib 223. After the outer mold 22 and the inner mold 21 between two adjacent casting cavities 3 are assembled, the protrusion 2231 abuts against the inner mold annular rib 212, thereby improving the overall structural strength of the inner mold 21 and the outer mold 22, so as to more reliably build the tower section or tower segment. Optionally, a plurality of protrusions 2231 are provided on the outer mold longitudinal rib 223, and the plurality of protrusions 2231 can abut against the inner mold annular rib 212 to improve the overall structural strength of the inner mold 21 and the outer mold 22. Of course, it can be understood that a plurality of protrusions 2231 can be provided on the outer mold longitudinal rib 223, the outer mold annular rib 222, the inner mold longitudinal rib 213, and the inner mold annular rib 212, so that the inner mold 21 and the outer mold 22 are pressed against each other, thereby improving the overall strength of the inner mold 21 and the outer mold 22.
