Description

Technical Field

[0001] The present invention relates to the technical field of precast pile forming, and more specifically, to a forming mold. Background Art

[0002] During the production of T-shaped piles, corresponding molds are often required. When producing T-shaped piles of different sizes, molds of different sizes are needed to adapt to the preparation of T-shaped piles of different specifications. Therefore, according to different incoming material orders, the T-shaped pile molds need to be adjusted accordingly. This involves mold replacement, and mold replacement requires a larger site, resulting in a very large actual floor area. This is because, generally, multiple T-shaped piles are formed simultaneously, so a large number of T-shaped molds are required, and the replaced T-shaped molds occupy a relatively large area and the replacement process is inconvenient.

[0003] In summary, how to effectively solve the problem of inconvenient replacement of T-shaped molds of different specifications at the construction site is an urgent problem that technicians in the current field need to solve. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to provide a forming mold, which can effectively solve the problem of inconvenient replacement of T-shaped molds of different specifications at the construction site.

[0007] In the above-mentioned forming die, a detachable first T-shaped die is arranged on the first bottom die. The first T-shaped die forms a T-shaped pile of a certain size specification through the second bottom die and the side die part. When it is necessary to form a T-shaped pile of another size specification, the first T-shaped die can be detached from the first bottom die. Then, during use, the first bottom die can be combined with other side die devices and / or the above-mentioned side die part to form a new T-shaped pile forming cavity for forming a T-shaped pile of another size specification. The first forming groove of the first bottom die can accommodate the corresponding protruding parts of the first T-shaped die, so that both sides of the first forming groove can support the first T-shaped die, making the fixation of the first T-shaped die more reliable and the overall structure more compact. Since the first bottom die does not need to be disassembled when the first T-shaped die is working, less space is required for replacing the die, making the replacement more convenient and the replacement operation simpler. In summary, the forming die can effectively solve the problem that it is inconvenient to replace T-shaped dies of different specifications at the construction site.

[0056] In some embodiments, as Figure 1 shown, a provided formed mold is a nested mold, that is, a first T-shaped mold is stacked on a first bottom mold 1 of a second T-shaped mold with a larger cross-sectional dimension. The first T-shaped mold can be called a small mold, and the T-shaped pile for forming can be called a small T-shaped pile; while the second T-shaped mold is called a large mold, and the T-shaped pile for forming can be called 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, it not only includes the first bottom mold 1, but also includes side mold devices, and the two side mold devices are respectively arranged on the lateral two sides of the first bottom mold 1 to combine and form a formed cavity with a T-shaped cross-section. The above-mentioned formed mold may include side mold devices or may not include side mold devices.

[0057] Among them, the first bottom mold 1 has a first forming groove 1-1 for forming the vertical part of the large T-shaped pile, and is placed in the chamber formed between the side mold devices on both sides 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, triangular, etc. For the sake of illustration, the width direction of the first forming groove 1-1 is the transverse direction, the depth direction is the up and down direction, and the extending direction is the longitudinal direction.

[0058] Among them, the first T-shaped mold includes a second bottom mold 2 and at least two side mold parts 3. The two sides of the second bottom mold 2 are lapped on both sides of the notch of the first forming groove 1-1, and can be further fixedly connected, such as by bolts, snap connections, etc. for detachable connection. By lapping the two sides of the second bottom mold 2 on both sides of the notch of the first forming groove 1-1, a certain supporting force is provided for the second bottom mold 2 by both sides of the notch of the first forming groove 1-1.

[0059] It should be noted that generally, the first T-shaped mold can be detachably and fixedly installed on the first bottom mold 1 so that: when it is necessary to form a small T-shaped pile, the first T-shaped mold is fixed on the first bottom mold 1 to achieve a nested setting; when it is not necessary to form a small T-shaped pile, the first T-shaped mold is removed from the first bottom mold 1, and the first bottom 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 be always retained on the first bottom mold 1, or can be installed on the first bottom mold 1 after the first T-shaped mold is removed. Of course, it can also be that the first T-shaped mold is not completely detachably and fixedly installed on the first bottom mold 1. For example, only the second bottom mold 2 of the first T-shaped mold can be detachably and fixedly installed on the first bottom mold 1, and the side mold part 3 is fixedly installed on the first bottom mold 1. At this time, the side mold part 3 and the first bottom mold 1 can also form a T-shaped pile forming groove with a large specification size.

[0060] Among them, the middle part of the second bottom mold 2 protrudes inwardly into the first forming groove 1-1, so as to protrude inwardly into the first forming groove 1-1 to make the upper mold surface 2-2 form a second forming groove 2-1 for forming the vertical part of the T-shaped pile, and the above-mentioned protruding part is accommodated by the first forming groove 1-1. Specifically, the middle part of the second bottom mold 2 has a groove-shaped structure part, and the notch of the groove-shaped structure part faces upward to serve as the vertical part of the small T-shaped pile, and the groove-shaped structure part protrudes inwardly into the first forming groove 1-1 relative to the two side parts of the second bottom mold 2 and is accommodated in the first forming groove 1-1. Through the above-mentioned sleeving method, the structure can be made more compact and the supporting effect on the first T-shaped mold is better.

[0061] Two relatively arranged side die parts 3 are respectively located on both sides of the second bottom die 2 and are connected to the upper die surface 2-2. They can be placed on the upper side of the second bottom die 2 or arranged horizontally side by side. Among them, the side die part 3 can be fixed on the second bottom die 2, or can be separately fixed on the first bottom die 1. It can also be that the side die part 3, the side part of the second bottom die 2 and the side part of the first bottom die 1 are stacked in sequence from top to bottom, and can be fixedly connected through the same connecting piece, such as a connecting bolt, etc. A transverse cavity for forming the transverse part of the T-shaped pile (small T-shaped pile) is formed between the two relatively arranged side die parts 3, that is, the transverse cavity and the second forming groove 2-1 are combined to 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 for forming at the end.

[0062] In the above-mentioned forming die, a detachable first T-shaped die is arranged on the first bottom die 1. The first T-shaped die forms a T-shaped pile of one size specification through the second bottom die 2 and the side die part 3. When it is necessary to form a T-shaped pile of another size specification, the first T-shaped die can be detached from the first bottom die 1. Then, when in use, the first bottom die 1 can be matched with other side die devices and / or the above-mentioned side die part 3 to combine and form a new T-shaped pile forming cavity for forming a T-shaped pile of another size specification. The first forming groove 1-1 of the first bottom die 1 can accommodate the corresponding protruding parts of the first T-shaped die, so that both sides of the first forming groove 1-1 can support the first T-shaped die, making the fixation of the first T-shaped die more reliable and the overall structure more compact. Because the first bottom die 1 does not need to be disassembled when the first T-shaped die works, the space required for replacing the die is smaller, making the replacement more convenient and the replacement operation simpler. To sum up, the forming die can effectively solve the problem that it is inconvenient to replace T-shaped dies of different specifications on the construction site.

[0063] Reference Figure 2 、 3 As shown in the figure, in some embodiments, the provided second bottom die 2 includes a bottom plate part 2-3 and a rib plate part 2-4. The upper side surface of the bottom plate part 2-3 forms the upper die surface 2-2, and the middle part is recessed downward so that a second forming groove 2-1 is formed on the upper side. The bottom plate part 2-3 can be an integrally formed steel plate, and the middle part of the steel plate is bent downward to form a groove structure, and the cavity of the groove structure is used as the above-mentioned second forming groove 2-1. The two side plates of the groove structure can be called wing plates, and the side plates are integrally connected to the notch edge of the groove structure. The upper side surface of the side plate and the inner groove wall of the groove structure both belong to the upper die surface 2-2. The thickness of the bottom plate part 2-3 can be set as required, specifically corresponding to the strength, such as a steel plate with a thickness of 1 cm, or a steel plate with a thickness of 8 mm. Of course, other dimensions can also be used, 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 each part is welded together.

[0064] The side panels of the bottom plate portion 2-3 overlap the first bottom mold 1 and are connected to the first bottom mold 1 via bolts. Alternatively, they can be fixed using other methods such as snap-fitting or composite connections, but they should be removable. For example, vertically extending through holes can be provided on the side panels to allow for the passage of bolts to connect to the lower first bottom mold 1. It should be noted that the side panels of the bottom plate portion 2-3 overlap the first bottom mold 1, and the lateral width of the side panels can be set according to the size of the corresponding T-piles to be formed. This allows for further consideration of strength and the resulting widening of the panels based on the above.

[0065] The rib portion 2-4 is disposed vertically, for example, perpendicularly to the upper mold surface 2-2. The rib portion 2-4 is disposed on the underside of the bottom plate portion 2-3 to reinforce the bottom plate portion 2-3 from the underside. The reinforcement primarily includes strengthening the groove structure and resisting bending, and may also involve strengthening other parts. The rib portion 2-4 is configured to cooperate with the first molding groove 1-1 in the groove width direction to achieve position limiting, so that the second bottom mold 2 is stuck in the first molding groove 1-1 and is limited by the rib portion 2-4.

[0066] The upper portion of the rib portion 2-4 is concave to match the lower convex portion of the bottom plate portion 2-3 to prevent significant deformation of the corresponding groove structure of the convex portion. Generally, the upper edge of the rib portion 2-4 is aligned with the lower side of the bottom plate portion 2-3. To ensure strong support, a plurality of rib portions 2-4 are generally arranged in parallel along the longitudinal direction on the lower side of the bottom plate portion 2-3. For example, two to three rib portions 2-4 can be evenly arranged.

[0067] In order to facilitate the passage of steam, each rib plate portion 2-4 can be provided with a through hole extending in the longitudinal direction, and the through holes of each rib plate portion 2-4 are aligned. It is used to pass a steam conducting pipe. At this time, a steam cavity is passed between the bottom plate portion 2-3 and the bottom of the first forming groove 1-1 to facilitate the passage of steam. Of course, the steam cavity can also be formed by combining in other ways. The rib plate portion 2-4 can be rectangular, and a recessed portion that is matched with the groove structure on the bottom plate portion 2-3 is provided in the middle of the upper edge to achieve avoidance, and the rib plate portion 2-4 is provided with the above-mentioned through holes on both sides of the recessed portion. The through hole can be set at the same height as the lower part of the recessed portion. The two ends of the upper edge of the rib plate portion 2-4 abut against the side panels on both sides of the bottom plate portion 2-3.

[0068] In some embodiments, as Figure 1As shown, considering that the strength may not be sufficient if only the side plates on both sides of the bottom plate portion 2-3 are lapped on both sides of the first bottom mold 1, especially when the lateral width of the first forming groove 1-1 is relatively large, at this time the lateral span of the bottom plate portion 2-3 is relatively large. Based on this, a support frame 4 that can be taken out can be provided in the first forming groove 1-1, wherein the lower part of the support frame 4 abuts against the bottom of the first forming groove 1-1, and the upper part abuts against the lower side of the second bottom mold 2. Specifically, the upper part of the support frame 4 can abut against the rib plate portion 2-4, or can abut against the lower side of the bottom plate portion 2-3.

[0069] In some embodiments, as shown in the attached Figure 5 、 6 Another second bottom mold 2 is provided, the overall cross-section of which is in a groove shape, and the groove part is used to form the second forming groove 2-1. The second bottom mold 2 includes an upper groove plate 2-5, a lower groove plate 2-6 and a groove-shaped rib plate 2-7 with a bent groove shape, and the three can be connected by welding or can be connected and fixed by bolts.

[0070] The upper groove plate 2-5 and the lower groove plate 2-6 are arranged in parallel and an air cavity is formed therebetween for introducing steam. The upper side surface of the upper groove plate 2-5 forms the above-mentioned upper mold surface 2-2, and the middle part of the upper groove plate 2-5 is recessed downward so that the second forming groove 2-1 is formed on the upper side, and wings 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 placed on the lower side of the upper groove plate 2-5, and the two are arranged in parallel, and it is sufficient to be close to parallel. At this time, the middle part of the lower groove plate 2-6 corresponds to the recessed part of the upper groove plate 2-5 and is correspondingly recessed. At this time, the upper groove plate 2-5 and the lower groove plate 2-6 are arranged in parallel so that the overall structure is in a groove shape.

[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 between the two. The groove-shaped rib plate 2-7 is erected relative to the lower groove plate 2-6 to play a supporting role therebetween. The upper edge of the groove-shaped rib plate 2-7 is matched with and abuts against the lower side of the upper groove plate 2-5, and the lower edge is matched 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 a groove shape so that the whole is in a groove shape. Generally, along the longitudinal direction, a plurality of groove-shaped rib plates 2-7 are arranged in sequence between the matched upper groove plate 2-5 and lower groove plate 2-6. The groove-shaped rib plate 2-7 can extend to both sides of the first forming groove 1-1 as shown in the attached Figure 7 to play an indirect support role; the groove-shaped rib plate 2-7 can also not extend to both sides of the first forming groove 1-1. At this time, the upper groove plate 2-5 can be directly lapped on both sides of the first forming groove 1-1, but the strength of this structure is not high.

[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, and the groove-shaped rib plates 2-7 can pass through or cross the above-mentioned sealing plates 2-8. At both ends in the longitudinal direction of the ventilation cavity, the two ends can be directly blocked by the groove-shaped rib plates 2-7 at both ends. One or more groove-shaped rib plates 2-7 can be arranged in the middle in the longitudinal direction of the ventilation cavity.

[0073] The groove-shaped rib plate 2-7 has a through hole to connect the ventilation cavities on the longitudinal two sides. When in use, in order to facilitate the introduction of steam into each cavity, the corresponding steam pipes can also be inserted through the above-mentioned through holes, and ventilation ports are opened at the corresponding cavities.

[0074] Both the lower groove plate 2-6 and the sealing plate 2-8 are located in the first forming groove 1-1, so that there is no need to form a large ventilation cavity. The two sides of the groove-shaped rib plate 2-7 overlap on the first bottom die. A plurality of groove-shaped rib plates 2-7 are arranged side by side in the longitudinal direction, and the thickness of the groove-shaped rib plates 2-7 at both ends can be greater than the thickness of the groove-shaped rib plates 2-7 in the middle. The lower parts on both sides of the upper groove plate 2-5 form connecting brackets 2-9 to overlap on the bottom die and are bolted together. 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, and the end parts of the two adjacent groove-shaped rib plates 2-7 are respectively connected to the two ends of a connecting plate, such as by welding, to form a connecting bracket 2-9. The connecting plate is stacked on the first bottom die 1 and is bolted together, and an operating space for operating the above-mentioned 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 disassembly and assembly.

[0075] As shown in the attached Figure 4 figure, at this time, a support frame 4 that can be taken out can also be provided in the first forming groove 1-1. The lower part of the support frame 4 abuts against the bottom of the first forming groove 1-1, and the upper part abuts against the lower side of the lower groove plate 2-6 for support. The side die parts 3 on both sides are preferably directly placed on the upper side of the upper groove plate 2-5.

[0076] In some embodiments, as shown in the attached Figure 8 、 9 figure, at least one of the side die parts 3 is a side convex forming die, which has a third forming groove 3-1 for forming a clamping convex. That is, a clamping convex is formed on one side of the small T-shaped pile, and on the other side of the small T-shaped pile, a clamping groove is generally formed. The clamping convex 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 convex and the clamping groove to prevent relative lateral movement between the two. The clamping convex can be a hook type or a dovetail type convex, mainly including a neck with a smaller size and a head with a larger size.

[0077] Correspondingly, the notch of the third forming groove 3-1 faces laterally and is a constricted opening, that is, the notch of the third forming groove 3-1 faces the transverse cavity. The third forming groove 3-1 includes an upper groove wall 3-11, a groove bottom 3-12, and a lower groove wall 3-13 that are 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 in a state where at least one section gradually increases in distance in the direction close to the groove bottom 3-12, so as to form a constricted opening on the side far from the groove bottom 3-12 to correspond to the neck of the above-mentioned clamping protrusion.

[0078] For the convenience of demolding, preferably, the side convex molding die here includes a detachably connected upper die part 3-2 and a lower die part 3-3. The upper groove wall 3-11 is arranged on the upper die part 3-2, and the lower groove wall 3-13 is arranged on the lower die part 3-3, so that the upper die part 3-2 can be moved upward and detached. After the small T-shaped pile is formed and it is necessary to remove the mold, the upper die part 3-2 can be removed first. At this time, after the connection constraint between the upper die part 3-2 and the lower die part 3-3, or the connection constraint between the upper die part 3-2 and other structures is released, the upper die part 3-2 can be moved upward. The groove bottom 3-12 can be arranged on the upper die part 3-2 or on the lower die part 3-3. If the groove bottom 3-12 prevents the upper die part 3-2 from moving upward, such as the lower end tilting towards the transverse cavity relative to the upper end, then the entire groove bottom 3-12 can be arranged on the lower die part 3-3. Considering that the groove bottom 3-12 is generally vertically arranged as shown in the attached drawing, at this time, a part of the groove bottom 3-12 can be arranged on the upper die part 3-2 and another part on the lower die part 3-3.

[0079] Specifically, the lower die part 3-3 can be placed on the upper die surface 2-2 and connected by bolts extending up and down, so as to be directly installed on the second bottom die 2. A first connecting plate 3-21 is arranged at the lower part of the upper die part 3-2 on the side of the groove bottom 3-12 far from the third forming groove 3-1. A second connecting plate 3-31 is arranged at the upper part of the lower die part 3-3 on the side of the groove bottom 3-12 far 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 is fixedly connected by bolts extending up and down.

[0080] Specifically, the upper die part 3-2 can include a first forming part. The first forming part and the first connecting plate 3-21 are strengthened by a plurality of rib plates. Correspondingly, the lower die part 3-3 includes a second forming part. The second forming part and the second connecting plate 3-31 are strengthened by a plurality of rib plates. The lower die part 3-3 has a bottom plate, which is stacked on the upper die surface 2-2 and is bolted to the second bottom die 2. A gap is provided between the bottom plate and the second connecting plate 3-31 to have a clearance space for operating the aforementioned bolts.

[0081] Specifically, the side convex forming die can also be called a split die. For example, the upper die part 3-2 and the lower die part 3-3 are separated from the middle up and down. When in use, the upper die part 3-2 can be disassembled first, as shown in the appendix Figure 9 As shown, at this time, the upper side of the lower die part 3-3 is open, so that the formed small T-shaped pile can be taken out from the lower die part 3-3, making the die disassembly more convenient and simple.

[0082] In some embodiments, as shown in the appendix Figure 10 、 11 As shown, at least one of the side die parts 3 is a side groove forming die. As shown in the appendix Figure 1 、 4 As shown, the side groove forming die and the side convex forming die are arranged oppositely. The side groove forming die includes a lateral support 3-4 and a forming protrusion 3-5 for forming a clamping groove. For a small T-shaped pile, there is not only a clamping groove on one side, but also a corresponding side surface connected to the notch of the clamping groove. Then the side groove forming die correspondingly has a forming surface for forming the above-mentioned side surface. The forming surface can be formed on the forming protrusion 3-5 or on the lateral support 3-4. For the convenience of taking out the forming protrusion 3-5, preferably a part is located on the forming protrusion 3-5 here, so that the forming protrusion 3-5 can continue to extend to both sides for convenient later application of force.

[0083] The lateral support 3-4 has a supporting inner protrusion 3-41 on the side close to the transverse cavity. The forming protrusion 3-5 has an inner groove 3-51 on the side far from the transverse cavity, which is inserted and matched with the supporting inner protrusion 3-41. When the supporting inner protrusion 3-41 is inserted into the inner groove 3-51, it can support the forming protrusion 3-5, so that the forming protrusion 3-5 can have sufficient strength to form the corresponding clamping groove.

[0084] Since the supporting inner protrusion 3-41 and the inner groove 3-51 are in insertion fit, the supporting inner protrusion 3-41 can withdraw from the inner groove 3-51. That is, during forming, the lateral support 3-4 can be disassembled first, and then the supporting protrusion can be disassembled. For the convenience of disassembly, for example, the supporting inner protrusion 3-41 can be made of a rectangular tube, and the inner groove 3-51 can be a rectangular groove with a matching cross-section.

[0085] When the supporting inner convex 3-41 exits the inner groove 3-51, the above-mentioned forming protrusion 3-5 can be deformed to a contracted state so as to be disengaged from the notch of the clamping groove in the contracted state. Specifically, the forming protrusion 3-5 can be a rubber strip or other strip-shaped members that are easy to deform. The specific deformation process is not limited because after the supporting inner convex 3-41 exits the inner groove 3-51, the inner groove 3-51 forms a space for the forming protrusion 3-5 to move during deformation. As shown in the attached figure, when the forming protrusion 3-5 disengages from the clamping groove, the upper part of the forming protrusion 3-5 can be first pressed downward. Since the thickness at each part is less than the width of the inner groove 3-51, that is, less than the width of the notch of the clamping groove, during the process of pressing the upper part downward, it gradually deforms and moves outward, and then the whole 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 better support it through the lateral support 3-4. Preferably, the above-mentioned forming protrusion 3-5 is fixedly connected to the supporting inner convex 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 be provided with 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 sequentially passes through the forming protrusion 3-5 and the lateral support 3-4. The lateral support 3-4 preferably includes a support plate 3-42 and a rectangular tube, where the rectangular tube constitutes the above-mentioned supporting inner convex 3-41, and the screw part of the fastening bolt 3-6 sequentially passes through the forming protrusion 3-5, the rectangular tube and the support plate 3-42 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] Wherein the forming protrusion 3-5 is a silica gel strip and the inner groove 3-51 is a rectangular groove. At this time, convex parts will be formed on both sides of the forming protrusion 3-5. Further, in order to avoid excessive weight, preferably, the convex parts of the forming protrusion 3-5 are provided with weight-reducing through holes, and the weight-reducing holes can be cylindrical holes, and of course, other hole structures are also possible. As shown in the attached figure, two weight-reducing through holes are provided on each of the convex parts on both sides.

[0088] In order to facilitate the installation of the side groove forming die, the side groove forming die can be fixedly installed on the second bottom die 2. Based on this, the lateral support 3-4 can be placed on the upper die surface 2-2 and connected by bolts extending up and down to facilitate disassembly.

[0089] In some embodiments, considering that the side die part 3 is only installed through the lower part, the lower part is prone to receive a relatively large torque. Further, a support device can be provided to support the side of the side die part 3 away from the transverse cavity.

[0090] Specifically, as attachedFigure 12 As shown, the support device can include a support nut 5 and a support screw 6. One side of the side mold part 3 away from the transverse cavity has a mounting groove, and the support nut 5 therein is fitted with the mounting groove and forms a limiting relationship in the transverse direction. In the longitudinal direction or the up-and-down direction, the support nut 5 can be snapped into the mounting groove. Specifically, a groove can be formed on the outer wall of the support nut 5 to be stuck in the mounting groove forming a bayonet.

[0091] The support screw 6 is in threaded fit with the support nut 5 to prevent the side mold part 3 from moving away from the transverse cavity. By rotating the support screw 6, the support strength can be adjusted. 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 side by side horizontally in sequence, correspondingly, multiple first T-shaped molds can be arranged side by side horizontally. Then, mounting grooves are provided on two adjacent first T-shaped molds, and correspondingly, two support nuts 5 are provided. At least one end of the support screw 6 is in threaded fit with the support nut 5 mounted on the first T-shaped mold, and the other end is in threaded fit with the support nut 5 mounted on another adjacent first T-shaped mold. Preferably, the threads at both ends are arranged in the opposite direction, so that when the support screw 6 rotates, the two support nuts 5 at both ends are pushed to move away from each other to achieve support adjustment. Specifically, the support nut 5 can be mounted on the side mold part 3 on the corresponding side.

[0092] For convenient operation, a hexagonal column or a square column for operating tools such as a wrench can be provided in the middle of the support screw 6. During installation, the distance between the two support nuts 5 at both ends can be adjusted to be equal to the distance between the two mounting grooves, so that the two support nuts 5 at both ends are respectively snapped into the mounting grooves at both ends, and then the support screw 6 is rotated to make the two support nuts 5 at both ends rotate away from each other. Further, to facilitate the rotation of the support nut 5, the rotation of the support nut 5 can be restricted by the mounting groove. Of course, it can also be restricted by other means.

[0093] In some embodiments, as shown in the appendix Figure 13 As shown, multiple groups of end mold groups can be arranged in sequence along the longitudinal direction to form multiple small T-shaped piles respectively in the longitudinal direction. Specifically, each group of end mold groups includes two end side forming molds 7 arranged side by side and oppositely along the longitudinal direction. At this time, a forming cavity for forming the small T-shaped pile is formed between the two end side forming molds 7. For the forming of the small T-shaped pile, the second bottom mold 2 forms the lower side of the small T-shaped pile, the two side mold parts 3 form the transverse two sides of the small T-shaped pile, and the two end side forming molds 7 form the longitudinal two sides of the small T-shaped pile. The specific shape of each forming surface can be set correspondingly according to the needs of the small T-shaped pile.

[0094] In actual work, the end-side forming die 7 needs to be connected to the longitudinal bars of the T-shaped pile to be formed, and then the longitudinal bars are tensioned. For this purpose, generally, in the two end-side forming dies 7 of a set of end modules, a tensioning mechanism is arranged on one side of one end-side forming die 7 away from the corresponding forming cavity, and the other end-side forming die 7 is limited by a limiting mechanism. The tensioning mechanism pulls the corresponding end-side forming die 7 to move relative to the other end-side forming die 7, thereby driving the longitudinal bars to be straightened.

[0095] If a tensioning mechanism and a limiting mechanism are arranged in each set of end modules, the overall volume will be relatively large, and the cost will also be relatively high. Based on this, it is preferably that adjacent end modules are connected by a connecting component. At this time, only one set of tensioning mechanism and limiting mechanism can be arranged, and multiple sets of end modules are arranged between the tensioning mechanism and the limiting mechanism. Adjacent end modules are connected by a connecting component, so that the tensioning mechanism pulls each end-side forming die 7 in turn through the longitudinal bars and the above-mentioned connecting component until the force is transmitted to the limiting mechanism. At this time, each longitudinal bar is subjected to tension, so that the longitudinal bars of multiple T-shaped piles can be pulled simultaneously by one tensioning mechanism. At this time, it is not necessary to arrange a tensioning mechanism and a limiting mechanism in each set of end modules, thereby greatly reducing the cost. The connecting component is used to transmit force between adjacent end modules and can be a simple connecting rod. Both ends of the connecting rod are clamped with the corresponding end-side forming die 7 to transmit the longitudinal tension.

[0096] If the connection is simply achieved by clamping, the operation is inconvenient. Based on this, it is preferably that the connecting component includes a first connecting column, a detachable connecting device and a second connecting column. One end of the first connecting column is threadedly connected to the end-side forming die 7 at the corresponding end, and the other end is in threaded connection with the threaded hole of the detachable connecting device. One end of the second connecting column is threadedly connected to the end-side forming die 7 at the corresponding other end, and the other end is in threaded connection with the threaded hole of the detachable connecting device. The detachable connecting device includes a plurality of split parts separated along the axial section of the threaded hole. For example, it is divided into two split parts. At this time, the detachable connecting device can also be called a half connecting device. The split parts are detachably connected, such as clamped or screwed. So that when disassembling, the first connecting column and / or the second connecting column can be disengaged from the detachable connecting device along the radial direction.

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

[0098] In some embodiments, such as Figure 18a , Figure 18b , Figure 18c As shown, in order to facilitate the formation of a protrusion 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. To facilitate the arrangement of the protrusion forming groove 723, the end-side forming die 3 can include a first forming template 721 and a second forming template 722 stacked in the longitudinal direction. The two are connected by welding or screw connection. Both the first forming template 721 and the second forming template 722 are integral structures. The outer contour of the first forming template 721 is T-shaped to correspond to the cross-section of the T-shaped pile. A forming hole penetrating longitudinally is opened in the middle of the first forming template 721. The second forming template 722 is attached to the back side (the side away from the forming side) of the first forming template 721 and covers the above-mentioned forming hole. The hole wall of the forming hole constitutes the groove wall of the protrusion forming groove 723, and the part corresponding to the forming hole on the side of the second forming template 722 facing the forming hole constitutes the groove bottom of the protrusion forming groove 723.

[0099] A feasible connection method between the first forming template 721 and the second forming template 722 can be: through holes can be provided on the edge of the second forming template 722, so that screws can pass through the through holes from the back side of the second forming template 722 to be threadedly connected with the screw holes of the first forming template 721. Multiple through holes are arranged in sequence and evenly along the edge of the second forming template 722.

[0100] Holes for connecting the longitudinal bars of the T-shaped pile are arranged on the first forming template 721 for installing connecting screws, and the connecting screws connect the longitudinal bars of the T-shaped pile. Avoidance grooves for avoiding the above-mentioned holes can be provided on the edge of the second forming template 722. Specifically, avoidance grooves can be provided on both sides of the second forming template 722. Connecting holes are provided on the second forming template 722 for connecting the connecting columns of the connecting component 9

[0101] In some embodiments, such as in the attached Figures 19a - 19eAs shown, generally, multiple T-shaped piles need to be formed in the longitudinal direction. For the convenience of installation, the bottom mold generally includes multiple segmented molds 1-8 that are butt-jointed in sequence along the longitudinal direction. The aforementioned bottom mold can be the first bottom mold 1 or the second bottom mold 2. The adjacent segmented molds 1-8 can be fixed in position with respect to each other through correspondingly installed structures. For example, they are fixed in position with respect to each other through the longitudinal beams provided on the support legs. However, the docking accuracy requirements between the segmented molds 1-8 are relatively high. It is very difficult to meet the accuracy requirements only by using the installation structure to confirm their positions with respect to each other. Generally, between adjacent segmented molds 1-8, a positioning pin 1-9 is also required to achieve positioning in the up-down direction and / or the lateral direction.

[0102] Specifically, the positioning pin 1-9 can be installed on one of the segmented molds 1-8 through a screw, and is engaged with the inverted U-shaped groove 1-10 of the other segmented mold 1-8. The notch of the inverted U-shaped groove 1-10 faces downward, and the groove width of the inverted U-shaped groove 1-10 is equal to the diameter of the positioning pin to achieve lateral positioning with respect to each other. And the bottom of the inverted U-shaped groove 1-10 abuts against the positioning pin 1-9 to achieve up-down positioning with respect to each other. The positioning pin 1-9 can be a cylindrical pin. Both ends of the two segmented molds 1-8 that are butt-jointed with each other can have an inverted U-shaped groove 1-10 and both have mounting holes for installing the positioning pin 1-9, so that the positioning pin 1-9 between the two segmented molds 1-8 can be installed on any one of the segmented molds 1-8 through a screw. For the convenience of installation and to avoid setting too many installation parts, when switching the installation, the positioning pin 1-9 can be reversed in the longitudinal direction. And the inverted U-shaped grooves 1-10 of the above two segmented molds 1-8 are respectively engaged with the positioning pin 1-9 that positions them with respect to each other. In some embodiments, as shown in the appendix Figure 14 As shown, multiple first bottom molds 1 can be arranged side by side in the lateral direction. However, the first bottom mold 1 needs to be fixed to the foundation. For the convenience of fixing, 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 to the foundation. However, in this way, the overall occupied space will be relatively large. Based on this, here it is preferred that the two lateral sides of the first bottom mold 1 respectively overlap on the support legs 8. The first bottom mold 1 and the support legs 8 are connected by an installation screw 9 extending up and down, and the disassembly operation part of the installation screw 9 is exposed through the window 1-2 opened on the upper side of the first bottom mold 1, so that from the window 1-2 opened on the upper side of the first bottom mold 1, the installation screw 9 can be operated to complete the installation between the support legs 8 and the first bottom mold 1, and the support legs 8 are fixed to the foundation. At this time, the first bottom molds 1 can be arranged side by side and closely adjacent to each other. And because the side mold device needs to be arranged on the upper side of the first bottom mold 1, there is space on the first bottom mold 1 for arranging the window 1-2.

[0103] In some embodiments, as shown in the appendix Figure 15 、 16As shown in the figure, 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 portion formed with a first forming groove 1-1 and two ear plate portions respectively connected to both sides of the groove portion. The ear plate portion can also be referred to as a wing plate portion.

[0104] The support rib plate 1-4 is vertically arranged relative to the forming template 1-3. 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 ventilation holes to facilitate the introduction of steam. The support rib plate 1-4 has a support portion corresponding to the ear plate portion. A connecting plate is connected to the lower side of the support portion. The ear plate portion, the support portion, the connecting plate, and the support leg 8 are arranged in sequence from top to bottom and are aligned. A window 1-2 is opened on the ear plate portion to expose the mounting screw 9 installed on the connecting plate.

[0105] Generally, the ear plate portion has a connecting through hole 1-6 for detachably connecting with the side mold device. 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 above window 1-2 can be arranged in alignment in the horizontal direction so that the side mold device can cover the window 1-2. When it is necessary to detach 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 is operated through the window 1-2 to be loosened, so that the first bottom mold 1 can be removed.

[0106] For the support leg 8, in order to facilitate support, a longitudinal beam 10 can also be provided. The longitudinal beam 10 is fixedly connected to the connecting plate through the mounting screw 9. A plurality of support legs 8 are arranged on the lower side of the longitudinal beam 10. The support leg 8 can be an I-beam, for example.

[0107] In this specification, each embodiment is described in a progressive manner. The key point of each embodiment is to illustrate the differences from other embodiments. The same or similar parts among the embodiments can be referred to each other.

Various modifications to these embodiments will be obvious to those skilled in the art. The general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention.
