[0026] The embodiments of the present application are described in detail below, and examples of the embodiments 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 application, and cannot be understood as limiting the present application.

[0027] Reference below Figure 3A mold 100 for installing tower segments 201 according to an embodiment of the present application is described. The mold 100 is used to fix two adjacent tower segments 201 together, and during specific installation, the outer walls of the two tower segments 201 can be kept flush, and the two tower segments 201 can be stably connected to ensure that the potting seam 202 between the two tower segments 201 is effectively closed, prevent leakage during the potting process, and improve the stability and reliability of the splicing of the tower segments 201.

[0028] like Figure 3 As shown, the mold 100 for installing the tower segment 201 according to the embodiment of the present application includes: a loading component 1 and a template 2.

[0029] It should be noted that the tower includes a plurality of concrete tower sections 200, and the plurality of concrete tower sections 200 are sequentially arranged. Figure 1 As shown, a plurality of concrete tower sections 200 may be lifted one by one to form an intermediate support section of the tower.

[0030] like Figure 2 As shown, the concrete tower section 200 includes a plurality of tower segments 201 connected in sequence along the circumferential direction, that is, the concrete tower section 200 is composed of a plurality of tower segments 201 spliced ​​in sequence along the circumferential direction. The mold 100 of the present application is used to splice and install two adjacent tower segments 201 of the concrete tower section 200 so that the two tower segments 201 are effectively encapsulated as one.

[0031] like Figure 3 As shown, the loading assembly 1 includes a first mounting position and a second mounting position, and the first mounting position and the second mounting position are respectively used to connect to two adjacent tower segments 201. Figure 3 As shown, two adjacent tower segments 201 are spliced ​​along the circumferential direction, and the loading assembly 1 connects the two tower segments 201 as a whole, and the loading assembly 1 can load the first of the two adjacent tower segments 201 through the first installation position, and can load the second of the two adjacent tower segments 201 through the second installation position. In this way, the connection stability between the two tower segments 201 can be adjusted by adjusting the loading force of the loading assembly 1, thereby ensuring that the two tower segments 201 can be stably and reliably connected.

[0032] The template 2 has a third mounting position and a fourth mounting position, which are respectively used to connect to two adjacent tower segments 201, and the two adjacent tower segments 201 can be connected and fixed by the template 2. Thus, both the loading assembly 1 and the template 2 can connect the two adjacent tower segments 201 to improve the stability and reliability of the connection between the two adjacent tower segments 201.

[0033] Among them, Figure 3As shown, the template 2 has a mounting surface 21, and the mounting surface 21 is suitable for fitting with the outer wall surfaces of two adjacent tower segments 201, so that the outer wall surfaces of the two tower segments 201 remain flush, thereby achieving the installation and positioning of the tower segments 201, and further connecting the two tower segments 201 more accurately, ensuring that a complete concrete tower section 200 can be formed after multiple tower segments 201 are connected in sequence along the circumferential direction.

[0034] The template 2 is suitable for forming a vertical seam with two adjacent tower segments 201, such as Figure 3 As shown, the mounting surface 21 faces two tower segments 201, and the sides of two adjacent tower segments 201 facing each other and the mounting surface 21 together define a circumferentially closed potting joint 202. Concrete slurry is then poured into the potting joint 202 to achieve potting connection of the two tower segments 201, and during the potting process, the two tower segments 201 are always stably connected through the loading assembly 1 and the template 2, that is, the potting joint 202 is always in a circumferentially closed state, and the structural dimensional accuracy of the potting joint 202 is high. In this way, leakage of the poured concrete slurry can be prevented, the potting process can be ensured to be carried out reliably, and the rapid connection of the two tower segments 201 can be achieved.

[0035] According to the mold 100 for installing tower segments 201 in the embodiment of the present application, two adjacent tower segments 201 are connected via a loading assembly 1 and a template 2, which can improve the stability and reliability of the connection between the two tower segments 201, and the installation surface 21 of the template 2 fits with the two tower segments 201, so that the installation position of the tower segment 201 is more accurate, ensuring that the grouting seam 202 is closed along the circumferential direction, preventing leakage of concrete slurry during the grouting process, and improving the reliability and safety of the splicing of the tower segments 201.

[0036] In some embodiments, Figure 3 As shown, the loading assembly 1 includes a jack 11 and two bases 12, both ends of the jack 11 are connected to the two bases 12, and the first mounting position and the second mounting position are respectively provided on the two bases 12, that is, the loading assembly 1 is fixedly connected to two adjacent tower segments 201 through the two bases 12. The base 12 can be connected to the tower segment 201 by bolts, so that the loading assembly 1 and the tower segment 201 are detachable, which is convenient for installation and disassembly, so that the mold 100 can be flexibly used to connect different tower segments 201.

[0037] It should be noted that the jack 11 is disposed between the two bases 12, and the jack 11 can be used to load the two bases 12 so that the two bases 12 move toward or away from each other. In this way, when connecting two tower segments 201, the jack 11 drives the two bases 12 to move toward each other so that the two adjacent tower segments 201 are stably connected; after the two tower segments 201 are connected, the bolts are removed to separate the loading assembly 1 from the tower segment 201, and the disassembly and assembly process is simple and practical.

[0038] The template 2 is installed between two bases 12, and the jack 11 is located on the side of the template 2 away from the installation surface 21. Figure 3 As shown, the template 2 is installed between the jack 11 and the tower segment 201. When connecting two adjacent tower segments 201, the two tower segments 201 can be initially positioned and connected by the template 2, and then the two tower segments 201 can be reinforced by the loading assembly 1, and the loading force of the jack 11 can be adjusted to make the connection between the two tower segments 201 more stable, thereby ensuring the sealing of the potting seam 202 along the circumferential direction.

[0039] In some embodiments, Figure 4 As shown, there are multiple groups of loading components, and the multiple groups of loading components are arranged at intervals along the length direction of the template, and the spacing between any two adjacent groups of loading components in the multiple groups of loading components is h1, satisfying: 6m≤h1≤8m. For example, h1=6.5m, or h1=7m, or h1=7.5m, thus, the spacing between two adjacent jacks 11 is h1, and thus, the spacing between two adjacent jacks 11 is set within the above range, so that the two tower segments 201 can be reinforced at multiple positions of the connection by the loading components, improve the stability of the connection between the two tower segments 201, prevent the mold 100 from affecting other operations outside the concrete tower section 200, and improve the rationality of the structural design of the mold 100.

[0040] In some embodiments, the third mounting position and the fourth mounting position are mounting holes that penetrate the template 2, and the template 2 is connected to the tower segment 201 through the threaded fasteners 4 that penetrate the mounting holes, so that the two tower segments 201 are stably connected through the template 2. The template 2 is connected to the tower segment 201 through the threaded fasteners 4, which facilitates the installation and removal of the template 2 and the tower segment 201, so that the mold 100 can be used for different tower segments 201.

[0041] Among them, the third installation position and the fourth installation position are multiple groups, and the multiple groups of third installation positions and the multiple groups of fourth installation positions are arranged spaced apart along the length direction of the template 2, that is, Figure 4As shown, two adjacent tower segments 201 are connected to the template 2 through a plurality of threaded fasteners, and the distance between any two adjacent sets of third mounting positions or fourth mounting positions is h2, that is, Figure 4 As shown, the spacing between two adjacent threaded fasteners along the length direction of the template 2 is h2, satisfying: 2m≤h2≤3m, such as h2=2.2m, or h2=2.5m, or h2=2.8m. Setting the spacing between two adjacent threaded fasteners along the length direction of the template 2 within the above range can ensure that the template 2 can connect the two tower segments 201 more stably.

[0042] like Figure 3 As shown, the distance from the third mounting position to the first end of the template 2 along the width direction is equal to the distance from the fourth mounting position to the second end of the template 2 along the width direction, that is, the spacing from the positions of the two mounting holes of the template 2 to the two ends of the template 2 is equal, so that the connection stress at both ends of the template 2 is more uniform, and there will be no situation where the stress at one end of the template 2 is large and the stress at the other end is small, thereby ensuring that the structural stability of the two ends of the template 2 is relatively balanced, and improving the safety of the use of the template 2.

[0043] like Figure 3 As shown, the mold 100 further includes a rubber pad.

[0044] The rubber pad is installed on the installation surface 21 and is suitable for being clamped between the installation surface 21 and the tower segment 201. The rubber pad is an elastic member. In this way, the rubber pad is installed between the template 2 and the tower segment 201 to play a role in buffering and vibration reduction, thereby avoiding rigid contact between the template 2 and the tower segment 201 during the connection of the tower segment 201, preventing the structure of the template 2 or the tower segment 201 from being damaged and deformed too much, and improving the safety of the use of the mold 100.

[0045] like Figure 3 As shown, the rubber pad includes a first pad block 31 and a second pad block 32 .

[0046] The first cushion block 31 is suitable for being sandwiched between the third installation position and the first of two adjacent tower segments 201 , and the second cushion block 32 is suitable for being sandwiched between the fourth installation position and the second of two adjacent tower segments 201 .

[0047] Thus, the first cushion block 31 and the second cushion block 32 are respectively sandwiched between the two installation positions of the template 2 and the two tower segments 201, so that the first cushion block 31 and the second cushion block 32 can be removed and installed separately without affecting each other, which is convenient for removal and installation. When one of the first cushion block 31 and the second cushion block 32 is damaged, it only needs to be replaced separately, and the cost of maintenance and replacement is low.

[0048] The template 2 extends along the length direction of the tower segment 201, and the length of the template 2 is the same as the length of the tower segment 201. In this way, after the two tower segments 201 are spliced, the template 2 and the two tower segments 201 define a potting seam 202, so that the connection between the two tower segments 201 can be reinforced by potting, thereby effectively improving the stability of the connection of the tower segments 201, making the structure of the concrete tower section 200 more reliable.
