DETAILED DESCRIPTION

[0042] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but cannot be understood as limiting the present invention.

[0043] Reference Figure 1-Figure 21 The straight bolt hand hole box connection mold 100 and the tower mold having the straight bolt hand hole box connection mold 100 according to the embodiment of the utility model are described.

[0044] Figure 1 and Figure 2 As shown, the tower mold includes an inner mold 200, an outer mold 300, a bottom mold 400 and an end mold 500, and a straight bolt hand hole box connection mold 100. Among them, the outer mold 300 and the inner mold 200 are both annular, the outer mold 300 is sleeved with the inner mold 200 and is spaced from the inner mold 200, and the bottom mold 400 is located at the bottom of the inner mold 200 and the outer mold 300 and defines an annular casting cavity between the inner mold 200 and the outer mold 300.

[0045] At least a part of the end mold 500 is arranged in the casting cavity and divides the casting cavity. The end mold 500 is provided with a through hole 510, and the through hole 510 is used to penetrate the straight bolt hand hole box connection mold 100, and the straight bolt hand hole box connection mold 100 is used to dry connect the pipe segment formed by casting. Figure 1 As shown, the tower mold includes two end molds 500, which divide the casting cavity into two semi-arc cavities, and cast into the cavity to form two semi-arc tower segments. The straight bolt hand hole box connection mold 100 is used to dry-connect the vertical seams between the two segments so that the two can be spliced ​​into a complete tower section.

[0046] like Figure 8 As shown, the straight bolt hand hole box connection mold 100 includes: a hand hole box 1, a plug-in component 2, an embedded steel bar 3 and an embedded nut 4. The hand hole box 1 is used to be connected to the outer peripheral surface of the inner mold 200. The inner mold 200 is provided with an opening 210 connected to the inner cavity of the hand hole box 1. The opening 210 and the corresponding hand hole box are arranged to facilitate the operator to perform core rod installation or grouting operations from the inner side of the inner mold 200.

[0047] The connector component 2 includes a core rod 21 and a sleeve 22. One end of the core rod 21 is connected to the hand hole box 1, and the other end passes through a through hole 510 opened on the end mold 500. The sleeve 22 is sleeved with the core rod 21. A part of the sleeve 22 is adapted to be in the through hole 510 and is tightly fitted with the inner circumference of the through hole 510. In other words, the connector component 2 passes through the through hole 510 and is tightly fitted with the inner circumference of the through hole 510 (sealed fit).

[0048] The embedded steel bar 3 and the embedded nut 4 are embedded in the pipe segment, and one end of the embedded steel bar 3 is connected to one end of the embedded nut 4. Figure 5 As shown, the hand hole box 1 and the embedded nut 4 are located on both sides of the end die 500 in the circumferential direction of the inner die 200. The other end of the core rod 21 passes through the end die 500 and is connected to the embedded nut 4 located on the other side of the end die 500.

[0049] The plug-in component of the straight bolt hand hole box connection mold in the embodiment of the utility model fits tightly with the through hole of the end mold. The precise positioning between the plug-in component and the end mold is achieved through the tight fit between the plug-in component and the through hole, thereby ensuring the stability of the straight bolt hand hole box connection mold during casting, making the produced pipe segments subjected to balanced force, and ensuring the sealing between the plug-in component and the end mold, preventing slurry from entering the connection gap between the plug-in component and the end mold, facilitating demoulding, and avoiding damage to the end mold and the end face of the pipe segment.

[0050] The tower module provided by the embodiment of the utility model and having the above-mentioned straight bolt hand hole box connection mold has the characteristics of stable structure, good sealing performance and convenient demoulding.

[0051] In some specific embodiments, Fig. 9 As shown, the hand hole box 1 includes a panel 11, a side panel 12, a bottom panel 13 and a back panel 14. The side panel 12 is an arc-shaped panel, and the panel 11 and the back panel 14 are arranged opposite to each other and are respectively connected to the two ends of the side panel 12. The panel 11, the side panel 12, and the back panel 14 are all connected to the bottom panel 13, and define a chamber between the panel 11, the side panel 12, and the back panel 14 and the bottom panel 13.

[0052] The bottom plate 13 is connected to the outer circumference of the inner mold 200 by fastening bolts, and an opening (not shown in the figure) is provided on the bottom plate 13, which is opposite to and penetrates the opening 210 on the inner mold 200. Furthermore, the bottom plate 13 and the outer circumference of the inner mold 200 are sealed by double-sided tape, sealing gasket or other sealing methods to prevent leakage of grouting slurry.

[0053] like Fig. 9 As shown, a mounting through hole 111 is provided on the panel 11 for passing the core rod 21 therethrough.

[0054] Specifically, Fig.12 , Fig.13 , Fig.17 and Fig.18 As shown, the mandrel 21 is a straight bolt structure, and the mandrel 21 is provided with effective external threads at the outer peripheral surface adjacent to the two ends thereof. One end of the mandrel 21 passes through the mounting through hole 111 on the panel 11, extends into the chamber of the hand hole box 1, and is connected to the mounting nut 211 located in the chamber of the hand hole box 1, so as to relatively fix the mandrel 21 and the hand hole box 1. The other end of the mandrel 21 extends into the embedded nut 4, and is threadedly matched with the embedded nut 4.

[0055] Of course, in other embodiments, the outer circumferential surface of the core rod 21 may be provided with effective external threads.

[0056] In some embodiments, Figure 8-Figure 12 As shown, the sleeve 22 includes a bellows 221 and a sleeve section 222. One end of the bellows 221 abuts against the hand hole box 1, and the other end abuts against one end of the sleeve section 222. The other end of the sleeve section 222 abuts against the embedded nut 4. In other words, the two ends of the sleeve 22 abut against the hand hole box 1 and the embedded nut 4 respectively. One end of the core rod 21 extends from the end of the bellows 221 to be connected to the hand hole box 1, and the other end of the core rod 21 extends from the end of the sleeve end 222 to be connected to the embedded nut 4. The sleeve 22 completely isolates the core rod 21 from the casting cavity to prevent concrete from entering the sleeve 22 and sticking to the core rod 21 during casting.

[0057] like Figure 5 As shown, at least a portion of the sleeve section 222 is adapted to fit in the through hole 510, and the sleeve 222 passes through the through hole 510 and fits tightly with the inner circumference of the through hole 510. Through the cooperation between the sleeve section 222 and the through hole 510, the precise positioning and relatively stable position between the straight bolt hand hole box connection mold 100 and the end mold 500 are achieved, and at the same time, a good seal between the straight bolt hand hole box connection mold 100 and the end mold 500 is ensured.

[0058] When connecting the pipe segments, grouting can be performed between the bellows 221 and the core rod 21, so that the grouting material fills the gap between the bellows 221 and the core rod 21, that is, the wet connection is further combined on the basis of the dry connection scheme, so that the connection between the pipe segments is more stable. The use of the bellows 221 helps to strengthen the connection between the plug-in component 2 and the concrete.

[0059] In other embodiments, after the segments are cast and formed, the mold is removed, and the core rod 21 is taken out of the bellows 221. When the segments are connected, straight bolts are inserted into the bellows 221, and the straight bolts are fastened to the embedded nuts 4 to form a dry connection between the segments. When the segments are connected, grouting can also be performed between the bellows 221 and the straight bolts, so that the grouting material fills the gap between the bellows 221 and the straight bolts, that is, the wet connection is further combined on the basis of the dry connection scheme, so that the connection between the segments is more stable. It can be understood that the straight bolt can be a straight bolt with a similar structure and shape to the core rod 21, or a conventional straight bolt with a screw rod and a bolt head integrally formed. For example, the screw rod of the straight bolt is inserted into the bellows 221 and connected to the embedded nut 4, and the bolt head of the straight bolt is located in the hand hole box for tightening the straight bolt to ensure that there is sufficient tightening torque between the straight bolt and the embedded nut 4, and to ensure the connection strength between the straight bolt and the embedded nut 4.

[0060] During hoisting, since the segments are dry-connected by the straight bolt hand hole box connection mold 100 and have a high connection strength, they can be directly hoisted as a whole without affecting the progress of the tower hoisting construction. Grouting and maintenance after hoisting will not affect the construction period.

[0061] Preferably, the corrugated tube 221 is a PVC tube, which can effectively prevent adhesion between the core rod 1 and the concrete in the casting cavity and has a good anti-leakage effect. Alternatively, in other examples, the corrugated tube 221 can also be replaced by a steel tube.

[0062] Furthermore, in some embodiments, the sleeve section 222 includes multiple sub-segments that are sequentially connected to facilitate demoulding. After the casting is completed, when the tower mold is demoulded, the sub-segments can be sequentially pulled out from the through holes 510 of the end mold 500, which is more labor-saving and can effectively avoid damage to the sleeve section 222 and the end mold 500.

[0063] Furthermore, the stop end faces between two adjacent sub-tube segments are both conical surfaces. Compared with a flat stop end face, a conical stop end face between two adjacent sub-tube segments has a larger area, which can make the sealing effect between the sub-tube segments better, and the sub-tube segments limit each other in the radial direction, effectively avoiding misalignment between the sub-tube segments.

[0064] In some embodiments, Fig.12 , Fig.15 and Fig.16 As shown, the sleeve section 222 has a first end face 2223 and a second end face 2224 opposite to each other in the axial direction, and both the first end face 2223 and the second end face 2224 are conical surfaces. The outer diameter of the first end face 2223 gradually decreases in the axial direction away from the second end face 2224, and the outer diameter of the second end face 2224 gradually decreases in the axial direction away from the first end face 2223. A portion of the first end face 2223 extends into the bellows 221 and abuts against the end of the bellows 221, and a portion of the second end face 2224 extends into the embedded nut 4 and abuts against the end of the embedded nut 4. Such a setting realizes that the sleeve section 222 and the bellows 221, and the sleeve section 222 and the embedded nut 4 are mutually limited in the radial direction, effectively avoiding the sleeve section 222 and the bellows 221 or the embedded nut 4 from being misaligned, resulting in concrete leakage.

[0065] As an example, Figure 8 , Fig.11 , Fig.12 As shown, the sleeve section 222 includes a first sub-segment 2221 and a second sub-segment 2222, and the first sub-segment 2221 and the second sub-segment 2222 abut against each other in the axial direction. Fig.15As shown, the first sub-tube segment 2221 has a first end and a second end opposite to each other in the axial direction. The first end and the second end of the first sub-tube segment 2221 are both tapered, and the outer radial direction of the first end gradually decreases away from the second end, and the outer radial direction of the second end gradually decreases away from the first end. Fig.16 As shown, the second sub-tube segment 2222 has a third end and a fourth end that are opposite in the axial direction, and the outer radial direction of the third end gradually increases in the direction away from the fourth end, and the outer radial direction of the fourth end gradually decreases in the direction away from the third end. The end face of the second end of the first sub-tube segment 2221 and the end face of the third end of the second sub-tube segment 2222 are parallel to and abut against each other. The end face of the first end of the first sub-tube segment 2221 is the second end face 2224 of the sleeve segment 222, and the end face of the fourth end of the second sub-tube segment 2222 is the first end face 2223 of the sleeve segment 222.

[0066] like Figure 8 As shown, the outer circumference of the first sub-segment 2221 is flush with the outer circumference of the second sub-segment 2222 , and a portion of the first sub-segment 2221 and a portion of the second sub-segment 2222 fit within the through hole 510 and fit tightly against the inner circumference of the through hole 510 .

[0067] Optionally, the sleeve section 222 is a rubber tube section, so that the sealing effect between the sleeve section 222 and the embedded nut 4 and the bellows 221 is better.

[0068] Alternatively, if Figure 8 As shown, the length of the bellows 221 is greater than the length of the sleeve section 222 .

[0069] In some embodiments, Figure 8 , Fig.12 and Fig.14 As shown, the straight bolt hand hole box connection mold 100 also includes an embedded pad 5 and a sealing ring 6. The embedded pad 5 abuts against the outer side of the hand hole box 1, and the core rod 21 passes through the through hole on the embedded pad 5 and is connected to the hand hole box 1. The sealing ring 6 is sleeved with the core rod 21 and sealed between the sleeve 22 and the embedded pad 5. The core rod 21 and the hand hole box 1 are sealed through the sealing ring 6. The setting of the embedded pad 5 enhances the local compressive resistance when the pipe segments are connected and reduces stress concentration.

[0070] Furthermore, the embedded pad 5 is a steel pad, and the embedded pad 5 can be fixed to the outside of the hand hole box 1 by bolts.

[0071] like Fig.12 and Fig.14 As shown, the cross section of the sealing ring 6 is triangular, and the two opposite ends of the sealing ring 6 in the axial direction extend into the inner hole of the bellows 221 and the through hole of the embedded pad 5 respectively, and are tightly against the bellows 221 and the embedded pad 5 respectively to achieve sealing.

[0072] In some embodiments, Figure 5 and Figure 8 As shown, the embedded steel bars 3 are bent steel bars to enhance the connection with the concrete.

[0073] Optionally, the embedded steel bar 3 and the embedded nut 4 are an integrated structure, that is, the embedded steel bar 3 and the embedded nut 4 are integrally formed.

[0074] Optionally, the embedded steel bar 3 and the embedded nut 4 are separate structures, and one end of the embedded steel bar 3 extends into one end of the embedded nut 4 and forms a threaded fit with the internal thread of the embedded nut 4.

[0075] In some embodiments, Figure 5 As shown, the through hole 510 opened on the end mold 500 of the tower mold is an inclined hole, and there is an angle between the axial direction of the through hole 510 and the tangent direction of the inner mold 200. In addition, the axial directions of the core rod 21 and the sleeve 22 are the same as the axial direction of the through hole 510, and there is an angle between the axial direction of the core rod 21 and the axial direction of the sleeve 22 and the tangent direction of the inner mold 200. Making the through hole 510 an inclined hole can be more suitable for the extension angle of the core rod 21 and the sleeve 22 under normal circumstances, so that the straight bolt hand hole box connection mold 100 and the end mold 500 have a better matching relationship.

[0076] like Figure 7 As shown, the inner mold 200 is provided with a plurality of openings 210, and the plurality of openings 210 are arranged at intervals in the axial direction of the inner mold 200. Figure 3 , Figure 4 and Figure 6 As shown, the outer peripheral surface of the inner mold 200 is provided with a plurality of straight bolt hand hole box connection molds 100, the hand hole boxes 1 of the plurality of straight bolt hand hole box connection molds 100 correspond one to one with the plurality of openings 210, and the extension directions of two adjacent straight bolt hand hole box connection molds 100 are opposite. Fig.19 As shown, the end mold 500 is provided with a plurality of through holes 510, and the plurality of straight bolt hand hole box connection molds 100 correspond one to one with the plurality of through holes 510, as shown in FIG. Fig. 20 and Fig.21 As shown, the inclined directions of two adjacent through holes 510 are opposite to each other so as to match the straight bolt hand hole box connection mold 100 .

[0077] The plug-in component 2 of the straight bolt hand hole box connection mold 100 and the through hole 510 of the end mold 500 are closely matched to achieve precise positioning, so that the sleeve 22 and the core rod 21 sleeved thereon can maintain a specific angle. Multiple straight bolt hand hole box connection molds 100 are arranged in an orderly manner, so that the pipe segments produced by the tower mold of the embodiment of the utility model are subjected to balanced force.

[0078] According to the following Figure 19-21 An end mold 500 in a specific embodiment is described.

[0079] like Figure 19-21 As shown, the end mold 500 includes an end mold panel 520, a first pasting plate 530, a second pasting plate 540, a plurality of first inlays 550, and a plurality of second inlays 560. The first pasting plate 530 and the second pasting plate 540 are respectively pasted and connected to two side surfaces of the end mold panel 520, the first inlays 550 are connected to the side of the first pasting plate 530 away from the end mold panel 520, the plurality of first inlays 550 are arranged at intervals along the extension direction of the end mold panel 520, the second inlays 560 are connected to the side of the second pasting plate 540 away from the end mold panel 520, and the plurality of second pasting plates 540 are arranged at intervals along the extension direction of the end mold panel 520.

[0080] The setting of the first plate 530 and the second plate 540 reserves a grouting space for the wet connection of the dry-connected pipe segments, thereby further adding a wet connection on the basis of the dry connection, that is, adding a grouting connection on the basis of the bolt connection, thereby enhancing the structural stress-bearing performance of the vertical joints of the pipe segments.

[0081] After the mold is cast, the multiple first inserts 550 and the multiple second inserts 560 are arranged to form key grooves at the positions of the first inserts 550 and the second inserts 560. After the wet connection grouting, the shear resistance of the wet connection joints can be further enhanced, and the structural stress-bearing performance of the vertical joints of the pipe segments can be further enhanced.

[0082] The end mold panel 520 , the first pasting plate 530 , and the second pasting plate 540 are provided with through holes, and the through holes are correspondingly provided with inclined hole sleeves 570 . The middle through hole of the inclined hole sleeve 570 is a through hole 510 that is tangentially inclined relative to the inner mold 200 .

[0083] The tower mold with the end mold 500 of the above embodiment has the versatility of dry and wet connection, which can realize dry connection between segments and add grouting connection on the basis of bolt connection, thereby enhancing the structural stress performance of the vertical seams of the segments.

[0084] The tower mold with the end mold 500 of the above-mentioned embodiment can be improved on the basis of the structure of the original wet connection mold, by replacing the original end mold assembly of the original wet connection mold, replacing part of the inner mold piece or improving the inner mold piece to realize the dry-wet mold conversion, and thus the wet connection mold can be converted into a dry-wet connection universal tower module, without the need to replace the outer mold 300 and the bottom mold 400, with a high commonality rate of parts, which greatly reduces the mold production cost, and can also reuse the discarded molds, saving resources and reducing costs. The tower module provided by the embodiment of the utility model is used to produce tower segments, and the segments can be spliced ​​immediately after production. Since the segments have been dry-connected by the straight bolt hand hole box connection mold 100, they have a high connection strength, and can be directly hoisted as a whole, and grouting can be performed after hoisting, which does not affect the tower hoisting construction progress. The construction process is simple and efficient, saving the grouting maintenance time for segment splicing in the traditional wet connection scheme, and does not affect the construction period.
