[0056] In some embodiments, as Figure 1As shown, the provided forming mold is a sleeve mold, that is, the first T-shaped mold is stacked on the first base mold 1 of the second T-shaped mold with a larger cross-sectional size. The first T-shaped mold can be referred to as a small mold, and the T-shaped pile formed by the first T-shaped mold can be referred to as a small T-shaped pile. The second T-shaped mold can be referred to as a large mold, and the T-shaped pile formed by the second T-shaped mold can be referred to as a large T-shaped pile. The cross-sectional sizes of the small T-shaped pile and the large T-shaped pile are different, and the cross-sectional shapes can be the same or different. For the second T-shaped mold, not only the first base mold 1, but also the side mold device, which is arranged on both sides of the first base mold 1 to form a forming cavity with a T-shaped cross section. The above-mentioned forming mold can include a side mold device, or can not include a side mold device.

[0057] The first base mold 1 has a first forming groove 1-1 for forming the vertical part of the large T-shaped pile, and the chamber formed between the two side mold devices is used for forming the horizontal part of the large T-shaped pile. The cross section of the first forming groove 1-1 can be trapezoidal, rectangular, or triangular, etc. For the sake of explanation, the groove width direction of the first forming groove 1-1 is the transverse direction, the groove depth direction is the up-down direction, and the extension direction is the longitudinal direction.

[0058] The first T-shaped mold includes a second base mold 2 and at least two side mold parts 3, and the second base mold 2 is lapped on both sides of the groove opening of the first forming groove 1-1. Further fixed connection can be achieved, such as detachable connection through bolts, clamping, etc. The second base mold 2 is lapped on both sides of the groove opening of the first forming groove 1-1 to provide a certain support force to the second base mold 2 from both sides of the groove opening of the first forming groove 1-1.

[0059] It should be noted that generally, the first T-shaped mold can be detachably fixed and installed on the first base mold 1, so that: when the small T-shaped pile needs to be formed, the first T-shaped mold is fixed on the first base mold 1, so that the sleeve stacking can be achieved; and when the small T-shaped pile does not need to be formed, the first T-shaped mold is removed from the first base mold 1, and the first base mold 1 is combined with the above-mentioned side mold device to form a forming cavity for forming a large T-shaped pile. The side mold device can always remain on the first base mold 1, or can be installed on the first base mold 1 after the first T-shaped mold is removed. Of course, the first T-shaped mold can also be partially detachably fixed and installed on the first base mold 1, such as only the second base mold 2 of the first T-shaped mold can be detachably fixed and installed on the first base mold 1, and the side mold part 3 is fixed and installed on the first base mold 1. At this time, the side mold part 3 and the first base mold 1 can also form a T-shaped pile forming groove with a large size.

[0060] The middle part of the second bottom die 2 is protruded into the first forming groove 1-1, so that the upper die surface 2-2 forms a second forming groove 2-1 for forming the vertical part of the T-shaped pile, and the protruded part is accommodated in the first forming groove 1-1. Specifically, the middle part of the second bottom die 2 has a groove structure, the groove opening of the groove structure faces upward to serve as the vertical part of the small T-shaped pile, and the groove structure is protruded into the first forming groove 1-1 relative to the two side parts of the second bottom die 2 to be accommodated in the first forming groove 1-1. Through the above-mentioned sleeving mode, the structure is more compact, and the supporting effect of the first T-shaped die is better.

[0061] The two oppositely arranged side die parts 3 are respectively arranged on the two sides of the second bottom die 2 and are connected with the upper die surface 2-2, and can be arranged on the upper side of the second bottom die 2 or can be arranged transversely in parallel. The side die part 3 can be fixed on the second bottom die 2, or can be fixed on the first bottom die 1 alone, or the side die part 3, the side part of the second bottom die 2 and the side part of the first bottom die 1 can be stacked from top to bottom in turn, and can be fixed and connected through the same connecting member, such as connecting bolts. A transverse cavity for forming the horizontal part of the T-shaped pile (small T-shaped pile) is formed between the two oppositely arranged side die parts 3, that is, the transverse cavity and the second forming groove 2-1 form a forming cavity with a T-shaped cross section. Of course, the above-mentioned forming cavity generally also includes an end side forming die 7 to form the end part.

[0062] In the above-mentioned forming die, the first T-shaped die is arranged on the first bottom die 1 in a detachable manner, and the first T-shaped die forms a T-shaped pile with a certain size specification through the second bottom die 2 and the side die part 3. When another size specification of T-shaped pile needs to be formed, the first T-shaped die can be detached from the first bottom die 1, and then when used, the first bottom die 1 can be matched with other side die devices and / or the above-mentioned side die part 3 to form a new T-shaped pile forming cavity for forming another size specification of T-shaped pile. The first forming groove 1-1 of the first bottom die 1 can accommodate the corresponding protruded part of the first T-shaped die, so that the two sides of the first forming groove 1-1 can support the first T-shaped die, the first T-shaped die is more fixed and the overall structure is more compact. Because the first T-shaped die does not need to be detached from the first bottom die 1 when working, the space required for replacing the die is smaller, so that the replacement is more convenient and the operation is simpler. In summary, the forming die can effectively solve the problem that it is inconvenient to replace different specifications of T-shaped die in the construction site.

[0063] Reference Figure 2 , 3As shown, in some embodiments, the provided second bottom die 2 includes a bottom plate part 2-3 and a rib plate part 2-4, wherein the upper side of the bottom plate part 2-3 forms the upper die surface 2-2, and the middle part is concave to form a second forming groove 2-1 on the upper side. The bottom plate part 2-3 can be an integrally formed steel plate, which is bent downward in the middle part to form a groove structure, and the cavity of the groove structure serves as the second forming groove 2-1. The two side plates of the groove structure can be called wing plates, which are integrally connected with the groove opening of the groove structure. The upper side of the side plate and the inner groove wall of the groove structure belong to the upper die surface 2-2. The thickness of the bottom plate part 2-3 can be set as needed, and the specific setting is according to the strength, which can be 1 cm thick steel plate, or 8 mm thick steel plate, and of course other sizes such as 0.2 mm, 2 cm, etc. Of course, in other examples, the bottom plate part 2-3 can also be a spliced plate, and the parts are welded together.

[0064] The two side plates of the bottom plate part 2-3 are lapped on the first bottom die 1 and connected with the first bottom die 1 by bolts, and of course other connection methods such as clamping, composite connection, etc. can also be used for fixation, but they should be detachable. For example, through holes extending up and down can be provided on the two side plates for the screw rod of the bolt to pass through to connect the first bottom die 1 below. It should be noted that the two side plates of the bottom plate part 2-3 are lapped on the first bottom die 1, and the transverse width of the side plate can be set according to the size of the corresponding formed T pile, which can further consider the strength problem to be widened.

[0065] The rib plate part 2-4 is vertically arranged, which can be perpendicular to the upper die surface 2-2. The rib plate part 2-4 is arranged on the lower side of the bottom plate part 2-3 to strengthen the bottom plate part 2-3 from the lower side of the bottom plate part 2-3. The strengthening dimension mainly includes the strengthening of the groove structure and the bending resistance, and of course other parts can also be strengthened. The rib plate part 2-4 is arranged in the groove width direction to match the first forming groove 1-1 to achieve limiting, so that the second bottom die 2 is clamped in the first forming groove 1-1, and the limiting is achieved by the rib plate part 2-4.

[0066] The upper part of the rib plate part 2-4 is recessed to match the concave middle part of the bottom plate part 2-3, so as to avoid large deformation of the corresponding groove structure of the concave middle part. Generally, the upper edge of the rib plate part 2-4 is matched with the lower side of the bottom plate part 2-3. In order to ensure the strength support, a plurality of parallel arranged rib plate parts 2-4 are arranged in sequence on the lower side of the bottom plate part 2-3 in the longitudinal direction, such as two to three rib plate parts 2-4.

[0067] For the convenience of steam, each of the rib plate parts 2-4 can be provided with a through hole extending in the longitudinal direction, and the through holes of each of the rib plate parts 2-4 are arranged in alignment. The steam guide pipe is arranged through the through hole, and the steam cavity is formed between the bottom plate part 2-3 and the groove bottom of the first forming groove 1-1, so that the steam is conveniently introduced. Of course, the steam cavity can also be formed by other means. The rib plate part 2-4 can be rectangular, and the middle part of the upper edge is provided with a recessed part matched with the groove structure of the bottom plate part 2-3 to achieve avoidance. The rib plate part 2-4 is arranged on both sides of the recessed part. The through hole can be arranged at the same height as the low part of the recessed part. The two ends of the upper edge of the rib plate part 2-4 abut on the two side plates of the bottom plate part 2-3.

[0068] In some embodiments, as shown in Figure 1 , considering that only the two side plates of the bottom plate part 2-3 are lapped on both sides of the first bottom die 1, the strength may not be enough, especially when the transverse width of the first forming groove 1-1 is relatively large, and the transverse span of the bottom plate part 2-3 is relatively large. Based on this, the first forming groove 1-1 can be provided with a removable support frame 4. The lower part of the support frame 4 abuts on the groove bottom of the first forming groove 1-1, and the upper part abuts on the lower side of the second bottom die 2. The upper part of the support frame 4 can abut on the rib plate part 2-4, or can abut on the lower side of the bottom plate part 2-3.

[0069] In some embodiments, as shown in the accompanying Figure 5 , 6 , another second bottom die 2 is provided, and the overall cross section is in the form of a groove. The groove part is used to form the second forming groove 2-1. The second bottom die 2 includes an upper groove plate 2-5, a lower groove plate 2-6, and a groove type rib 2-7 bent in the form of a groove. The three are connected by welding or connected and fixed by bolts.

[0070] The upper groove plate 2-5 and the lower groove plate 2-6 are arranged in parallel and form an air cavity therebetween for the introduction of steam. The upper side of the upper groove plate 2-5 forms the upper die surface 2-2. The middle part of the upper groove plate 2-5 is recessed to form the second forming groove 2-1 on the upper side, and wing plates are formed on both sides of the second forming groove 2-1 to extend to both sides of the first forming groove 1-1. The lower groove plate 2-6 is arranged on the lower side of the upper groove plate 2-5, and the two are arranged in parallel. The middle part of the lower groove plate 2-6 is recessed to correspond to the recessed part of the upper groove plate 2-5. The upper groove plate 2-5 and the lower groove plate 2-6 are arranged in parallel to form a groove type structure.

[0071] The groove-shaped rib plate 2-7 is arranged between the upper groove plate 2-5 and the lower groove plate 2-6 and is connected therebetween. The groove-shaped rib plate 2-7 is vertically arranged relative to the lower groove plate 2-6 to support therebetween. The upper edge of the groove-shaped rib plate 2-7 is arranged in cooperation with and abuts against the lower side of the upper groove plate 2-5, and the lower edge of the groove-shaped rib plate 2-7 is arranged in cooperation with and abuts against the upper side of the lower groove plate 2-6. The upper edge and the lower edge of the groove-shaped rib plate 2-7 are both in the shape of a groove, so that the whole is in the shape of a groove. A plurality of groove-shaped rib plates 2-7 are arranged in sequence between the upper groove plate 2-5 and the lower groove plate 2-6 in the longitudinal direction. As shown in the accompanying drawings, the groove-shaped rib plate 2-7 can extend to both sides of the first formed groove 1-1 to indirectly support. The groove-shaped rib plate 2-7 can also not extend to both sides of the first formed groove 1-1. In this case, the upper groove plate 2-5 can be directly lapped on both sides of the first formed groove 1-1, but the strength of this structure is not high. Figure 7

[0072] The transverse two sides of the lower groove plate 2-6 are provided with sealing plates 2-8 to seal the transverse two sides of the ventilation cavity. The groove-shaped rib plate 2-7 can pass through the sealing plate 2-8 or pass over the sealing plate 2-8. The longitudinal two ends of the ventilation cavity can be directly blocked by the groove-shaped rib plates 2-7 at the two ends. One or more groove-shaped rib plates 2-7 can be arranged in the longitudinal middle part of the ventilation cavity.

[0073] The groove-shaped rib plate 2-7 has a through hole to realize the communication of the ventilation cavities on the longitudinal two sides. In use, in order to facilitate the steam into each cavity, a corresponding steam pipeline can be inserted through the through hole, and a ventilation opening is formed at the corresponding cavity.

[0074] The lower groove plate 2-6 and the sealing plate 2-8 are located in the first formed groove 1-1, so that a larger ventilation cavity does not need to be formed. The groove-shaped rib plates 2-7 are arranged in parallel in the longitudinal direction. The thickness of the groove-shaped rib plates 2-7 at the two ends can be greater than the thickness of the groove-shaped rib plates 2-7 in the middle. The lower part of the two sides of the upper groove plate 2-5 forms a connecting bracket 2-9 to be lapped on the bottom die and bolted therebetween. It should be noted that for the groove-shaped rib plates 2-7 in the middle, every two groove-shaped rib plates 2-7 can be arranged close to each other. The two ends of the two close groove-shaped rib plates 2-7 are connected to the two ends of a connecting plate, such as welded connection, to form a connecting bracket 2-9. The connecting plate is stacked on the first bottom die 1 and bolted therebetween. An operation space for operating the bolts is formed between the upper side of the connecting plate and the lower side of the side plate of the upper groove plate 2-5 to complete the disassembly and assembly.

[0075] As shown in the accompanying drawings, the groove-shaped rib plate 2-7 can extend to both sides of the first formed groove 1-1 to indirectly support. The groove-shaped rib plate 2-7 can also not extend to both sides of the first formed groove 1-1. In this case, the upper groove plate 2-5 can be directly lapped on both sides of the first formed groove 1-1, but the strength of this structure is not high. Figure 4 ​As shown, at this time, the support frame 4 in the first forming groove 1-1 can also be taken out, wherein the lower part of the support frame 4 abuts against the groove bottom of the first forming groove 1-1, and the upper part abuts against the lower side of the lower groove plate 2-6 to support. The side mold parts 3 on both sides are preferably placed directly on the upper side of the upper groove plate 2-5.

[0076] In some embodiments, as shown in the accompanying drawings, at least one of the side mold parts 3 is a side protrusion forming mold having a third forming groove 3-1 for forming a clamping protrusion. Figure 8 、 9 As shown, at least one of the side mold parts 3 is a side protrusion forming mold having a third forming groove 3-1 for forming a clamping protrusion. That is, a clamping protrusion is formed on one side of the small T-shaped pile, and the other side of the small T-shaped pile is generally used to form a clamping groove. The clamping protrusion and the clamping groove are structurally matched, so that when a plurality of small T-shaped piles are arranged side by side, they can be clamped and matched with each other through the clamping protrusion and the clamping groove to prevent relative lateral movement between them. The clamping protrusion can be a clamping hook type or a dovetail type protrusion, mainly including a neck part with a smaller size and a head part with a larger size.

[0077] Correspondingly, the slot side of the third forming groove 3-1 is laterally arranged and is a contraction opening, that is, the slot side of the third forming groove 3-1 faces the lateral cavity, and the third forming groove 3-1 includes an upper groove wall 3-11, a groove bottom part 3-12 and a lower groove wall 3-13 arranged in sequence and combined to form a groove structure. The distance between the upper groove wall 3-11 and the lower groove wall 3-13 is gradually increased at least in a direction close to the groove bottom part 3-12, so that a contraction opening is formed on the side away from the groove bottom part 3-12 to correspond to the neck part of the clamping protrusion.

[0078] In order to facilitate demolding, the side protrusion forming mold preferably includes a detachably connected upper mold part 3-2 and a lower mold part 3-3, the upper groove wall 3-11 is arranged on the upper mold part 3-2, and the lower groove wall 3-13 is arranged on the lower mold part 3-3, so that the upper mold part 3-2 can be moved upward to be detached. When the small T-shaped pile is formed and needs to be demolded, the upper mold part 3-2 can be detached first, and then the connection constraint between the upper mold part 3-2 and the lower mold part 3-3 is released or the connection constraint between the upper mold part 3-2 and other structures is released, so that the upper mold part 3-2 can be moved upward. The groove bottom part 3-12 can be arranged on the upper mold part 3-2 or the lower mold part 3-3. If the groove bottom part 3-12 prevents the upper mold part 3-2 from moving upward, such as the lower end being inclined to the lateral cavity relative to the upper end, the groove bottom part 3-12 can be arranged entirely on the lower mold part 3-3. Considering that the groove bottom part 3-12 is generally arranged vertically as shown in the accompanying drawings, a part of the groove bottom part 3-12 can be arranged on the upper mold part 3-2 and the other part can be arranged on the lower mold part 3-3.

[0079] Specifically, the lower mold part 3-3 can be placed on the upper mold surface 2-2 and connected to it by bolts extending vertically, so that it can be directly installed on the second bottom mold 2. The lower part of the upper mold part 3-2 is provided with a first connecting plate 3-21 located on the side of the bottom of the groove 3-12 away from the third forming groove 3-1, and the upper part of the lower mold part 3-3 is provided with a second connecting plate 3-31 located on the side of the bottom of the groove 3-12 away from the third forming groove 3-1. The first connecting plate 3-21 is stacked on the upper side of the second connecting plate 3-31 and the two are fixedly connected by bolts extending vertically.

[0080] Specifically, the upper mold portion 3-2 may include a first forming portion, which is reinforced with a first connecting plate 3-21 by multiple ribs. The corresponding lower mold portion 3-3 includes a second forming portion, which is reinforced with a second connecting plate 3-31 by multiple ribs. The lower mold portion 3-3 has a base plate that is stacked on the upper mold surface 2-2 and bolted to the second bottom mold 2. A gap is provided between the base plate and the second connecting plate 3-31 to allow for the operation of the aforementioned bolts.

[0081] The specific side-protrusion forming mold can also be called a parting mold. For example, it can be separated into an upper mold part 3-2 and a lower mold part 3-3 from the middle. In use, the upper mold part 3-2 can be disassembled first, as shown in the attached figure. Figure 9 As shown, the upper side of the lower mold part 3-3 is open at this time, so that the formed small T-shaped pile can be removed from the lower mold part 3-3. This makes demolding more convenient and simple.

[0082] In some embodiments, as shown in the appendix Figure 10 , 11 As shown, at least one of the side mold portions 3 is a side groove forming mold, as illustrated in the attached diagram. Figure 1 , 4 As shown, the side groove forming mold and the side protrusion forming mold are arranged opposite to each other. The side groove forming mold includes a lateral support 3-4 and a forming protrusion 3-5 with a forming slot. For a small T-shaped pile, one side not only has a slot, but also a corresponding side surface connected to the slot opening. The side groove forming mold has a forming surface for forming the above-mentioned side surface. This forming surface can be formed on the forming protrusion 3-5 or on the lateral support 3-4. To facilitate the removal of the forming protrusion 3-5, it is preferable that a portion of it is located on the forming protrusion 3-5 so that the forming protrusion 3-5 can continue to extend to both sides to facilitate subsequent force application.

[0083] The support inner protrusion 3-41 is inserted into the inner groove 3-51, and the forming protrusion 3-5 is supported to have sufficient strength to form the corresponding card slot.

[0084] Because the support inner protrusion 3-41 and the inner groove 3-51 are inserted and matched, the support inner protrusion 3-41 can be withdrawn from the inner groove 3-51, that is, the lateral support 3-4 can be disassembled first, and then the support protrusion is disassembled. In order to facilitate disassembly, the support inner protrusion 3-41 can be a rectangular tube, and the inner groove 3-51 is a rectangular groove with a matching cross section.

[0085] When the support inner protrusion 3-41 is withdrawn from the inner groove 3-51, the above-mentioned forming protrusion 3-5 can be deformed to a contracted state to be able to be separated from the card slot in the contracted state. The specific forming protrusion 3-5 can be a rubber strip or other strip-shaped member that is easy to deform. The specific deformation process is not limited, because after the support inner protrusion 3-41 is withdrawn from the inner groove 3-51, the inner groove 3-51 forms a space in which the forming protrusion 3-5 can move when deformed. As shown in the drawings, when the forming protrusion 3-5 is separated from the card slot, the upper part of the forming protrusion 3-5 can be pressed down first. Because the thickness of each part is less than the width of the inner groove 3-51, that is, less than the slot width of the card slot, the upper part is gradually deformed and moved outward during the pressing process, and then the entire forming protrusion 3-5 is pulled out.

[0086] Considering that the forming protrusion 3-5 is a structure that is easy to deform, in order to be better supported by the lateral support 3-4. Here, the above-mentioned forming protrusion 3-5 is fixedly connected with the support inner protrusion 3-41 through a fastening bolt 3-6, and the disassembly operation part of the fastening bolt 3-6 is exposed on the side of the lateral support 3-4 away from the transverse cavity. Specifically, the fastening bolt 3-6 can have a large nut part to abut against the side of the forming protrusion 3-5 away from the lateral support 3-4, and the screw part passes through the forming protrusion 3-5 and the lateral support 3-4 in sequence. The lateral support 3-4 preferably includes a support plate 3-42 and a rectangular tube, wherein the rectangular tube constitutes the above-mentioned support inner protrusion 3-41, and the screw part of the fastening bolt 3-6 passes through the forming protrusion 3-5, the rectangular tube and the support plate 3-42 in sequence and is exposed on the side of the support plate 3-42 away from the rectangular tube. The support plate 3-42 can be connected to the lower side plate of the lateral support 3-4 through a rib plate to form a support structure.

[0087] The protrusion 3-5 is a silicone strip, and the groove 3-51 is a rectangular groove. Protrusions are formed on both sides of the protrusion 3-5. Furthermore, to avoid excessive weight, the protrusions of the protrusion 3-5 preferably have weight-reducing through holes, which can be cylindrical holes or other hole structures. As shown in the attached diagram, each protrusion has two weight-reducing through holes.

[0088] To facilitate the installation of the side groove forming mold, it can be fixedly mounted on the second bottom mold 2. Based on this, the lateral supports 3-4 can be placed on the upper mold surface 2-2 and connected by bolts extending vertically, facilitating disassembly.

[0089] In some embodiments, considering that the side mold portion 3 is installed only from the bottom, the bottom portion is prone to receiving relatively large torque. Furthermore, a support device can be provided to support the side of the side mold portion 3 away from the lateral cavity.

[0090] For details, see attached. Figure 12 As shown, the support device can include a support nut 5 and a support screw 6. The side mold portion 3, away from the transverse cavity, has a mounting groove, and the support nut 5 therein engages with the mounting groove, forming a limiting relationship in the transverse direction. In the longitudinal or vertical direction, the support nut 5 can be engaged into the mounting groove. Specifically, the outer wall of the support nut 5 can form a groove to engage in the mounting groove forming a snap-fit.

[0091] The support screw 6 is threadedly engaged with the support nut 5 to prevent the side mold portion 3 from moving away from the transverse cavity. The support strength can be adjusted by rotating the support screw 6. One end of the support screw 6 is connected to the support nut 5, and the other end can abut against the first bottom mold 1. Generally, when multiple first bottom molds 1 are arranged transversely side by side, multiple first T-shaped molds can be arranged transversely side by side. Each adjacent first T-shaped mold has a mounting groove and correspondingly two support nuts 5. At least one end of the support screw 6 is threadedly engaged with the support nut 5 installed on the first T-shaped mold, and the other end is threadedly engaged with the support nut 5 installed on another adjacent first T-shaped mold. Preferably, the threads at both ends are opposite, so that when the support screw 6 rotates, it pushes the support nuts 5 at both ends to move away from each other, thereby achieving support adjustment. Specifically, the support nut 5 can be installed on the corresponding side mold portion 3.

[0092] For the convenience of operation, the middle part of the supporting screw rod 6 can be provided with a hexagonal column or a square column for the operation of a wrench or the like. When installing, the distance between the two supporting nuts 5 at the ends can be adjusted to be equal to the distance between the two installation grooves, so that the two supporting nuts 5 at the ends are respectively clamped into the installation grooves at the ends, and then the supporting screw rod 6 is rotated to move the two supporting nuts 5 away from each other. Further, in order to facilitate the rotation of the supporting nut 5, the rotation of the supporting nut 5 can be limited by the installation groove, and of course it can also be limited by other ways.

[0093] In some embodiments, as shown in the accompanying drawings, a plurality of groups of end mold groups can be arranged in sequence along the longitudinal direction to respectively form a plurality of small T-shaped piles in the longitudinal direction. Specifically, each group of end mold groups includes two end side forming molds 7 arranged side by side along the longitudinal direction and opposite to each other, at this time the two end side forming molds 7 form a forming cavity for forming a small T-shaped pile. For the forming of the small T-shaped pile, the second bottom mold 2 is for the lower side of the small T-shaped pile, the two side mold parts 3 are for the two sides of the small T-shaped pile in the transverse direction, and the two end side forming molds 7 are for the two sides of the small T-shaped pile in the longitudinal direction. The specific shape of each forming surface can be correspondingly set according to the needs of the small T-shaped pile. Figure 13 In actual work, the end side forming mold 7 needs to be connected with the longitudinal reinforcement of the T-shaped pile to be formed, and then the longitudinal reinforcement is pulled. For this purpose, generally one of the two end side forming molds 7 in a group of end mold groups is provided with a tensioning mechanism on the side away from the corresponding forming cavity, and the other end side forming mold 7 is limited by a limiting mechanism. The tensioning mechanism moves the end side forming mold 7 on the corresponding side relative to the other end side forming mold 7, thereby driving the longitudinal reinforcement to be straightened.

[0094] If each group of end mold groups is provided with a tensioning mechanism and a limiting mechanism, the overall volume will be relatively large, and the cost will also be relatively large. Based on this, it is preferred that adjacent end mold groups are connected by a connecting assembly, at this time the tensioning mechanism and the limiting mechanism can be provided only in one group, and a plurality of groups of end mold groups are provided between the tensioning mechanism and the limiting mechanism, and adjacent end mold groups are connected by the connecting assembly, so that the tensioning mechanism pulls each end side forming mold 7 in sequence through the longitudinal reinforcement and the above connecting assembly until the force is transmitted to the limiting mechanism. At this time, each longitudinal reinforcement is subjected to tension, so that one tensioning mechanism can simultaneously pull the longitudinal reinforcement of a plurality of T-shaped piles. At this time, each group of end mold groups does not need to be provided with a tensioning mechanism and a limiting mechanism, thereby greatly reducing the cost. The connecting assembly is used to transmit force between adjacent end mold groups, which can be a simple connecting rod, and the connecting rod is connected to the corresponding end side forming mold 7 at both ends to transmit the longitudinal tension.

[0095]

[0096] ​If the connection is achieved simply by clamping, the operation is inconvenient, and based on this, the connection assembly here preferably includes a first connecting column, a detachable connecting device, and a second connecting column, wherein one end of the first connecting column is threadedly connected with the end side of the corresponding one end forming die 7, and the other end is connected with the threaded hole of the detachable connecting device. One end of the second connecting column is threadedly connected with the end side of the corresponding other end forming die 7, and the other end is connected with the threaded hole of the detachable connecting device. The detachable connecting device includes a plurality of split parts arranged separately along the axial section of the threaded hole, such as two split parts, at which time the detachable connecting device can also be referred to as a half connecting device. The split parts are detachably connected, such as clamping, or screw connection, etc. So that when disassembled, the first connecting column and / or the second connecting column can be separated from the detachable connecting device in the radial direction.

[0097] In some embodiments, as shown in Figure 17a 、 Figure 17b The end side forming die 3 can include a tension plate 711 and a group of rib plates 712 arranged on the back of the tension plate 711, wherein the tension plate 711 has the same cross-sectional structure as the T-shaped pile, and the whole is T-shaped, including a horizontal part and a vertical part, wherein the two ends of the horizontal part have dovetail grooves and dovetail protrusions that are structurally matched with each other, so that adjacent T-shaped piles can be clamped in sequence through the dovetail grooves and dovetail protrusions of each other. The tension plate 711 is generally an integral forming structure, and the group of rib plates are arranged staggered in the horizontal and vertical directions.

[0098] In some embodiments, as shown in Figure 18a 、 Figure 18b 、 Figure 18c In order to facilitate the formation of protrusions at the end of the T-shaped pile, a protrusion forming groove 723 is generally formed on the forming side of the end side forming die 3. In order to facilitate the arrangement of the protrusion forming groove 723, the end side forming die 3 can include a first forming die plate 721 and a second forming die plate 722 stacked in the longitudinal direction, which are welded or connected by screws, wherein the first forming die plate 721 and the second forming die plate 722 are both integral structures, the outer contour of the first forming die plate 721 is T-shaped to correspond to the cross section of the T-shaped pile, wherein the middle part of the first forming die plate 721 is provided with a forming hole penetrating through in the longitudinal direction, the second forming die plate 722 is arranged on the back side (the side away from the forming side) of the first forming die plate 721 and covers the above-mentioned forming hole, the hole wall of the forming hole constitutes the groove wall of the above-mentioned protrusion forming groove 723, and the part of the side of the second forming die plate 722 facing the forming hole corresponding to the forming hole constitutes the groove bottom of the protrusion forming groove 723.

[0099] One feasible connection method for the first forming template 721 and the second forming template 722 is as follows: the edge of the second forming template 722 may be provided with through holes, so that screws can pass through the through holes from the back side of the second forming template 722 to be threadedly connected to the screw holes of the first forming template 721. Multiple through holes are arranged sequentially and evenly along the edge of the second forming template 722.

[0100] The first forming template 721 has holes for connecting the longitudinal reinforcement of the T-shaped piles, which are used to install connecting bolts. The connecting bolts connect to the longitudinal reinforcement of the T-shaped piles. The edge of the second forming template 722 may be provided with clearance grooves to avoid the aforementioned holes; specifically, clearance grooves may be provided on both sides of the second forming template 722. The second forming template 722 also has connecting holes for connecting the connecting column of the connecting assembly 9.

[0101] In some embodiments, as shown in the appendix Figures 19a to 19e As shown, multiple T-shaped piles are typically formed in the longitudinal direction. For ease of installation, the bottom formwork generally includes multiple segmented molds 1-8 connected sequentially along the longitudinal direction. These bottom molds can be either the first bottom mold 1 or the second bottom mold 2. Adjacent segmented molds 1-8 can be fixed in position with corresponding installation structures, such as longitudinal beams mounted on the support legs. However, the connection accuracy between segmented molds 1-8 is relatively high, and simply confirming their position through installation structures is insufficient to meet these requirements. Generally, adjacent segmented molds 1-8 also require locating pins 1-9 for vertical and / or horizontal positioning.

[0102] Specifically, the locating pins 1-9 can be screwed onto one of the segment molds 1-8, and onto the inverted U-shaped groove 1-10 of the other segment mold 1-8. The groove opening of the inverted U-shaped groove 1-10 faces downwards, and the groove width of the inverted U-shaped groove 1-10 is equal to the diameter of the locating pin, thus achieving lateral positioning. The bottom of the inverted U-shaped groove 1-10 abuts against the locating pin 1-9, thus achieving vertical positioning. The locating pin 1-9 can be a cylindrical pin, and both ends of the two segment molds 1-8 that meet each other have inverted U-shaped grooves 1-10 and mounting holes for installing the locating pin 1-9, so that the locating pin 1-9 between the two segment molds 1-8 can be screwed onto either segment mold 1-8. To facilitate installation and avoid setting too many mounting parts, the locating pin 1-9 can be reversed in the longitudinal direction when switching installations. Furthermore, the inverted U-shaped grooves 1-10 of each of the two segment molds 1-8 mate with the locating pins 1-9 that position each other. In some embodiments, as shown in the appendix Figure 14As shown, the first bottom mold 1 can be arranged side by side in the transverse direction, but the first bottom mold 1 needs to be fixed on the foundation. In order to facilitate fixation, a gap needs to be formed between adjacent first bottom molds 1 to provide an operating space so that each first bottom mold 1 can be fixed on the foundation. However, this will result in a relatively large overall floor space. Based on this, the first bottom mold 1 is preferably overlapped on the support leg 8 on both sides in the transverse direction, wherein the first bottom mold 1 is connected with the support leg 8 through the mounting screw 9 extending upward and downward, and the dismounting operation part of the mounting screw 9 is exposed through the window 1-2 opened on the upper side of the first bottom mold 1, so that the mounting screw 9 can be operated through the window 1-2 opened on the upper side of the first bottom mold 1 to complete the installation between the support leg 8 and the first bottom mold 1, and the support leg 8 is fixed on the foundation. At this time, the first bottom molds 1 can be arranged side by side and abutted. Because the upper side of the first bottom mold 1 needs to be arranged with the side mold device, the first bottom mold 1 has space to arrange the window 1-2.

[0103] In some embodiments, as shown in the accompanying drawings, Figure 15 、 16 Specifically, the first bottom mold 1 can include a forming template 1-3, a support rib plate 1-4, and a sealing bottom plate 1-5. The forming template 1-3 includes a groove part formed with a first forming groove 1-1 and two ear plate parts connected to both sides of the groove part, respectively. The ear plate part can also be referred to as a wing plate part.

[0104] The support rib plate 1-4 is arranged vertically relative to the forming template 1-3, and the upper side edge of the support rib plate 1-4 is arranged in cooperation with the forming template 1-3 to form a groove structure. The sealing bottom plate 1-5 is located below the forming template 1-3 and has a ventilation cavity therebetween, and is provided with a ventilation hole to facilitate the introduction of steam. The support rib plate 1-4 has a support part corresponding to the ear plate part, and the lower side of the support part is connected with a connecting plate. The ear plate part, the support part, the connecting plate, and the support leg 8 are arranged in sequence from top to bottom and are aligned. The ear plate part is provided with a window 1-2 to expose the mounting screw 9 mounted on the connecting plate.

[0105] Generally, the ear plate part has a connecting through hole 1-6 for detachable connection with the side mold device, and the side mold device cooperates with the first bottom mold 1 to form a T-shaped pile forming groove. The connecting through hole 1-6 and the window 1-2 described above can be arranged in alignment in the transverse direction, so that the side mold device can cover the window 1-2. When it is necessary to dismount the first bottom mold 1, the side mold device can be removed first to expose the window 1-2, and then the mounting screw 9 can be operated through the window 1-2 to loosen, so that the first bottom mold 1 can be removed.

[0106] Wherein the support leg 8, in order to facilitate support, can also be provided with longitudinal beam 10, longitudinal beam 10 and connecting plate through mounting screw 9 fixedly connected, the lower side of longitudinal beam 10 is arranged with a plurality of support legs 8, wherein the support leg 8 such as can be I-beam.

[0107] The various embodiments in the specification are described in a progressive manner, and each embodiment focuses on the difference from other embodiments, and the same or similar parts between various embodiments can be referred to each other.

[0108] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present application. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
