[0049] In some embodiments, a precast pile die is provided, which is mainly used for forming a T-shaped pile, wherein the T-shaped pile mainly comprises a horizontal part and a vertical part, which are vertically or nearly vertically arranged, and one end of the vertical part is connected with the middle part of the horizontal part to combine to form a T-shaped structure.

[0050] The precast pile die mainly comprises a bottom die 1 and at least two side die parts 2, wherein the bottom die 1 is used for forming the lower side of the horizontal part and the vertical part, and the two oppositely arranged side die parts 2 are respectively used for forming the two sides of the horizontal part.

[0051] The two oppositely arranged side die parts 2 are respectively arranged on both sides of the bottom die 1 and are used for forming the two sides of the horizontal part of the T-shaped pile. The side die part 2 is detachably mounted on the upper die surface to be supported by the upper die surface and connected with the upper die surface to combine into a continuous filtering surface. The detachable mounting between the side die part 2 and the bottom die 1 can be achieved by bolt connection, welding, etc. to realize fixed connection.

[0052] The two oppositely arranged side die parts 2 form a horizontal cavity for forming the horizontal part of the T-shaped pile (not shown) between them, that is, the horizontal cavity and the first forming groove 1-1 combine to form a forming cavity with a T-shaped cross section. Of course, the above-mentioned forming cavity generally also comprises an end side forming die 3 for forming the end part.

[0053] In the above-mentioned precast pile die, the bottom die 1 is arranged, and the side die part 2 is arranged on both sides of the bottom die 1 respectively, so as to combine the bottom die 1 and the side die part 2 to form a T-shaped forming cavity. The detachable mounting of the side die part 2 and the bottom die 1 makes the final structure forming convenient. Therefore, the precast pile die can effectively solve the problem of inconvenient operation of the T-shaped precast pile die.

[0054] In some embodiments, when it is necessary to form a lateral clamping protrusion, the current side die part 2 is not convenient to remove after forming. As shown in the drawings, at least one of the side die parts 2 is a side protrusion forming die 2-1, which has a second forming groove 2-11 for forming a clamping protrusion. That is, a clamping protrusion is formed on one side of the T-shaped pile, and the other side of the small T-shaped pile is generally used for forming a clamping groove. The clamping protrusion and the clamping groove are matched in structure, so that when a plurality of 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, so as to prevent the relative lateral movement of the two. The clamping protrusion can be a clamping hook type or a dovetail type protrusion, mainly comprising a neck part with a smaller size and a head part with a larger size.

[0055] Correspondingly, the second forming groove 2-11 is provided with a slot side facing towards and is a shrinkage opening, that is, the slot of the second forming groove 2-11 faces towards the transverse cavity, the second forming groove 2-11 comprises an upper groove wall 2-111, a groove bottom 2-112 and a lower groove wall 2-113 which are sequentially arranged and combined to form a groove structure, the distance between the upper groove wall 2-111 and the lower groove wall 2-113 gradually increases at least in a direction close to the groove bottom 2-112, so that a shrinkage opening is formed on the side away from the groove bottom 2-112 to correspond to the neck of the clamping protrusion.

[0056] In order to facilitate demolding, the side protrusion forming mold 2-1 preferably comprises a detachably connected upper mold part 2-12 and a lower mold part 2-13, the upper groove wall 2-111 is arranged on the upper mold part 2-12, and the lower groove wall 2-113 is arranged on the lower mold part 2-13, so that the upper mold part 2-12 can be moved upward to be detached. After the T-shaped pile forming is completed, when the mold needs to be removed, the upper mold part 2-12 can be removed first, and then the connection constraint between the upper mold part 2-12 and the lower mold part 2-13 or the connection constraint between the upper mold part 2-12 and other structures is released, and then the upper mold part 2-12 can be moved upward. The groove bottom 2-112 can be arranged on the upper mold part 2-12 or the lower mold part 2-13. If the groove bottom 2-112 prevents the upper mold part 2-12 from moving upward, for example, the lower end is inclined towards the transverse cavity relative to the upper end, then the groove bottom 2-112 can be arranged on the lower mold part 2-13. Considering that the groove bottom 2-112 is generally arranged vertically as shown in the drawings, the groove bottom 2-112 can be arranged on the upper mold part 2-12 and the lower mold part 2-13.

[0057] In the above-mentioned side protrusion forming mold 2-1, along the separation surface passing through the groove bottom 2-112, the upper mold part 2-12 and the lower mold part 2-13 are separated, so that in use, the upper mold part 2-12 and the lower mold part 2-13 are connected to form the second forming groove. When the mold needs to be removed, the upper mold part 2-12 can be removed first, and then the formed T-shaped pile can be taken out without the constraint of the upper mold part 2-12. Specifically, the upper mold part 2-12 and the lower mold part 2-13 can be separated along the symmetry plane of the second forming groove.

[0058] In some embodiments, the lower mold part 2-13 can be placed on the upper mold surface and connected by bolts extending upward and downward, so as to be directly installed on the second bottom mold 1. The upper mold part 2-12 is provided with a first connecting plate 2-121 on the side of the groove bottom 2-112 away from the second forming groove 2-11, and the lower mold part 2-13 is provided with a second connecting plate 2-131 on the side of the groove bottom 2-112 away from the second forming groove 2-11. The first connecting plate 2-121 is stacked on the upper side of the second connecting plate 2-131 and is fixedly connected by bolts extending upward and downward.

[0059] Specifically, the upper mold part 2-12 can include a first forming part, and the first forming part and the first connecting plate 2-121 are reinforced by a plurality of rib plates. The corresponding lower mold part 2-13 includes a second forming part, and the second forming part and the second connecting plate 2-131 are reinforced by a plurality of rib plates. The lower mold part 2-13 has a bottom plate to be stacked on the upper mold surface and connected with the second bottom mold 1 by bolts. The gap between the bottom plate and the second connecting plate 2-131 is provided to have a gap space for operating the bolts.

[0060] In some embodiments, in order to facilitate the molding of the above-mentioned card slot, at least one of the side mold parts 2 is a side groove forming mold 2-2, and the side groove forming mold 2-2 and the side protrusion forming mold 2-1 are oppositely arranged. The side groove forming mold 2-2 includes a lateral support 2-21 and a forming protrusion 2-22 for forming a card slot. For a T-shaped pile, on one side, not only has a card slot, but also has a side surface connected with the slot of the card slot. Therefore, the side groove forming mold 2-2 correspondingly has a forming surface for forming the above-mentioned side surface. The forming surface can be formed on the forming protrusion 2-22 or on the lateral support 2-21. In order to facilitate the removal of the forming protrusion 2-22, it is preferred that a part of the forming protrusion 2-22 is located on the forming protrusion 2-22, so that the forming protrusion 2-22 can continue to extend to both sides to facilitate the later force.

[0061] The side of the lateral support 2-21 close to the transverse cavity has a support inner protrusion 2-211, and the side of the forming protrusion 2-22 away from the transverse cavity has an inner groove 2-221 matched with the support inner protrusion 2-211. When the support inner protrusion 2-211 is inserted into the inner groove 2-221, the forming protrusion 2-22 can be supported, so that the forming protrusion 2-22 can have sufficient strength to form the corresponding card slot.

[0062] Because the support inner convex 2-211 and the inner groove 2-221 are inserted and matched, the support inner convex 2-211 can be withdrawn from the inner groove 2-221, that is, the lateral support 2-21 can be detached first, and then the support convex is detached during the forming. In order to facilitate disassembly, the support inner convex 2-211 can be a rectangular tube, and the inner groove 2-221 is a rectangular groove with a matching cross section.

[0063] When the support inner convex 2-211 is withdrawn from the inner groove 2-221, the above-mentioned forming convex 2-22 can be deformed to or dispersed to a contracted state, so as to be able to be separated from the card slot in the contracted state; or the forming convex 2-22 can be dispersed into a plurality of parts which are separated from the card slot, that is, after the support inner convex 2-211 is withdrawn, each part can be sequentially separated from the card slot.

[0064] Specifically, the forming convex 2-22 can be a rubber strip or other strip-shaped member which is convenient to deform. The specific deformation process is not limited, because after the support inner convex 2-211 is withdrawn from the inner groove 2-221, the inner groove 2-221 forms a space in which the forming convex 2-22 can move during deformation. As shown in the drawings, when the forming convex 2-22 is separated from the card slot, the upper part of the forming convex 2-22 can be pressed downward first. Since the thickness of each part is smaller than the width of the inner groove 2-221, that is, smaller 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 convex 2-22 is pulled out.

[0065] Considering that the forming convex 2-22 is a structure which is easy to deform, in order to be better supported by the lateral support 2-21. Here, the above-mentioned forming convex 2-22 is preferably fixedly connected with the support inner convex 2-211 through a fastening bolt 2-23, and the dismounting operation part of the fastening bolt 2-23 is exposed on the side of the lateral support 2-21 away from the transverse cavity. Specifically, the fastening bolt 2-23 can have a large nut part to abut against the side of the forming convex 2-22 away from the lateral support 2-21, and the screw rod part sequentially passes through the forming convex 2-22 and the lateral support 2-21. The lateral support 2-21 preferably includes a support plate and a rectangular tube, wherein the rectangular tube constitutes the above-mentioned support inner convex 2-211, and the screw rod part of the fastening bolt 2-23 sequentially passes through the forming convex 2-22, the rectangular tube and the support plate, and is exposed on the side of the support plate away from the rectangular tube. The support plate can be connected to the lower side plate of the lateral support 2-21 through a web plate to form a support structure 2-212. The lower side plate can be connected to the upper die face through a bolt.

[0066] An example is that the rectangular tube can be welded or bolted on the support structure 2-212, which makes the rectangular tube and the support structure 2-212 move away from the forming convex 2-22 at the same time after forming.

[0067] Another example is that the rectangular tube can be detachably fixed on the support structure 2-212, which makes it possible to remove the connecting bolts between the support structure 2-212 and the upper die surface after forming, then take out the support structure 2-212 upward, and finally take out the rectangular tube transversely. At this time, only space for transverse movement of the rectangular tube needs to be reserved. This scheme can be more convenient and save transverse space. The fixing method between the rectangular tube and the support structure 2-212 can be fixed connection through the above-mentioned fastening bolts 2-23.

[0068] Wherein the forming protrusion 2-22 is a silica gel strip, and the inner groove 2-221 is a rectangular groove. At this time, the two sides of the forming protrusion 2-22 will form protruding parts. Further, in order to avoid excessive weight, the protruding parts of the forming protrusion 2-22 are preferably provided with weight-reducing holes. The weight-reducing holes can be cylindrical holes, and of course can also be other hole structures. As shown in the drawings, the protruding parts on both sides are provided with two weight-reducing holes.

[0069] In order to facilitate the installation of the side groove forming die 2-2, the side groove forming die 2-2 can be fixedly installed on the bottom die 1. Based on this, the lateral support 2-21 can be placed on the upper die surface and connected by the up and down extending bolts to facilitate disassembly.

[0070] In some embodiments, considering that the side die part 2 is only installed by the lower part, the lower part is easily subjected to relatively large torque. Further, a supporting device can be provided to support the side of the side die part 2 away from the transverse cavity.

[0071] Specifically, the supporting device can include a supporting nut and a supporting screw. The side of the side die part 2 away from the transverse cavity has a mounting groove, and the supporting nut therein cooperates with the mounting groove and forms a limiting relationship in the transverse direction. In the longitudinal direction or the up and down direction, the supporting nut can be clamped into the mounting groove. Specifically, the outer wall of the supporting nut can form a groove to be clamped in the mounting groove forming a bayonet.

[0072] The support screw is threadedly connected with the support nut at one end and threadedly connected with the support nut at the other end. When a plurality of bottom molds 1 are arranged side by side in the transverse direction, a plurality of side mold portions 2 corresponding to the bottom molds 1 are arranged side by side in the transverse direction. The support screw is threadedly connected with the support nut arranged in the side mold portion 2 corresponding to the adjacent bottom mold 1 at one end and threadedly connected with the support nut arranged in the side mold portion 2 corresponding to the adjacent bottom mold 1 at the other end. The two ends of the support screw are arranged in opposite directions, so that when the support screw is rotated, the two support nuts are moved away from each other, thereby adjusting the support strength.

[0073] In order to facilitate operation, the middle part of the support screw can be provided with a hexagonal column or a square column for operation of a wrench or the like. When installing, the distance between the two support nuts can be adjusted to be equal to the distance between the two installation grooves, so that the two support nuts are respectively clamped into the installation grooves at the two ends, and then the support screw is rotated to move the two support nuts away from each other. Further, in order to facilitate rotation of the support nut, the rotation of the support nut can be limited by the installation groove, and of course other limiting methods can also be used.

[0074] In some embodiments, as shown in the drawings, a plurality of end mold groups can be arranged in the longitudinal direction in sequence to form a plurality of T-shaped piles in the longitudinal direction. Specifically, each end mold group includes two end side forming dies 3 arranged side by side in the longitudinal direction and opposite to each other, and a forming cavity for forming a T-shaped pile is formed between the two end side forming dies 3. For the formation of the T-shaped pile, the bottom mold 1 is used to form the lower side of the T-shaped pile, the two side mold portions 2 are used to form the transverse sides of the T-shaped pile, and the two end side forming dies 3 are used to form the longitudinal sides of the T-shaped pile. The specific shape of each forming surface can be set according to the needs of the T-shaped pile.

[0075] In actual work, the end side forming die 3 needs to be connected with the longitudinal reinforcement of the T-shaped pile to be formed, and then the longitudinal reinforcement is tensioned. For this purpose, generally one of the two end side forming dies 3 in a set of end module groups is provided with a tensioning mechanism on the side away from the corresponding forming cavity, and the other end side forming die 3 is limited by a limiting mechanism. The tensioning mechanism moves the corresponding end side forming die 3 relative to the other end side forming die 3, thereby driving the longitudinal reinforcement to straighten.

[0076] If each set of end module 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, the adjacent end module groups are connected by the connecting assembly 9 at this time, and the tensioning mechanism and the limiting mechanism can be provided only in one set, and a plurality of end module groups are provided between the tensioning mechanism and the limiting mechanism, and the adjacent end module groups are connected by the connecting assembly 9, so that the tensioning mechanism sequentially pulls each end side forming die 3 through the longitudinal reinforcement and the connecting assembly 9, 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 multiple T-shaped piles. At this time, each set of end module groups does not need to be provided with a tensioning mechanism and a limiting mechanism, thereby greatly reducing the cost. The connecting assembly 9 is used to transmit force between adjacent end module groups, which can be a simple connecting rod. The connecting rod is connected to the corresponding end side forming die 3 at both ends to transmit the longitudinal tension.

[0077] If the connection is simply achieved by clamping, the operation is not convenient. Based on this, the connecting assembly 9 preferably 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 3 at the corresponding end, and the other end is connected to the threaded hole of the detachable connecting device. One end of the second connecting column is threadedly connected to the end side forming die 3 at the other corresponding end, and the other end is connected to the threaded hole of the detachable connecting device. The detachable connecting device includes a plurality of split parts separated along the axial cross section of the threaded hole, such as two split parts. At this 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. When disassembled, the first connecting column and / or the second connecting column can be separated from the detachable connecting device in the radial direction.

[0078] In some embodiments, as Figure 10a , Figure 10bAs shown, the end-side forming mold 3 can include a tension plate 311 and a rib plate group 312 arranged on the back of the tension plate 311, wherein the tension plate 311 has the same cross-sectional structure as the T-shaped pile, and has a T-shaped overall structure including a horizontal part and a vertical part, wherein the two ends of the horizontal part are respectively provided with dovetail grooves and dovetail protrusions which are structurally matched with each other, so that adjacent T-shaped piles can be sequentially clamped by the dovetail grooves and the dovetail protrusions of each other. The tension plate 311 is generally an integral forming structure, and the rib plate group is arranged in a staggered manner in the horizontal and vertical directions.

[0079] In some embodiments, as shown in the accompanying drawings, Figure 11a 、 Figure 11b 、 Figure 11c As shown, in order to facilitate the formation of protrusions at the end of the T-shaped pile, a protrusion forming groove 323 is generally formed on the forming side of the end-side forming mold 3. In order to facilitate the arrangement of the protrusion forming groove 323, the end-side forming mold 3 can include a first forming mold plate 321 and a second forming mold plate 322 stacked along the longitudinal direction, which are connected by welding or through screws. The first forming mold plate 321 and the second forming mold plate 322 are both integral structures, and the first forming mold plate 321 has a T-shaped outer contour to correspond to the cross-section of the T-shaped pile. The middle part of the first forming mold plate 321 is provided with a forming hole which penetrates through the longitudinal direction. The second forming mold plate 322 is arranged on the back side (the side away from the forming side) of the first forming mold plate 321 and covers the forming hole. The hole wall of the forming hole constitutes the groove wall of the protrusion forming groove 323, and the part of the side of the second forming mold plate 322 corresponding to the forming hole constitutes the groove bottom of the protrusion forming groove 323.

[0080] A feasible connection method of the first forming mold plate 321 and the second forming mold plate 322 can be that the edge of the second forming mold plate 322 is provided with through holes, so that the screws can pass through the through holes from the back side of the second forming mold plate 322 to be screwed with the screw holes of the first forming mold plate 321. A plurality of through holes are arranged in sequence and uniformly along the edge of the second forming mold plate 322.

[0081] The first forming mold plate 321 is provided with holes for connecting the longitudinal reinforcement of the T-shaped pile, for installing connecting screws which connect the longitudinal reinforcement of the T-shaped pile. The edge of the second forming mold plate 322 can be provided with avoiding grooves for avoiding the above-mentioned holes, and the avoiding grooves can be arranged on both sides of the second forming mold plate 322. The second forming mold plate 322 is provided with connecting holes for connecting the connecting columns of the connecting assembly 9.

[0082] In some embodiments, as shown in the accompanying drawings, Figures 12a to 12eAs shown, generally need to form multiple T-shaped piles in the longitudinal direction. In order to facilitate installation, generally the bottom die 1 includes multiple segmented molds 1-8 which are sequentially butt-jointed in the longitudinal direction, and the adjacent segmented molds 1-8 can be fixed in position with each other through the corresponding installed structure. For example, through the longitudinal beams arranged on the support legs to be fixed in position with each other. However, the butt-jointing accuracy between the segmented molds 1-8 is relatively high, and it is difficult to achieve the accuracy requirement only by the installation structure to confirm the position of each other. Generally, the adjacent segmented molds 1-8 also need to be positioned in the upward and / or lateral direction through the positioning pins 1-9.

[0083] The specific positioning pin 1-9 can be installed on one of the segmented molds 1-8 through a screw, and the inverted U-shaped groove 1-10 of the other segmented mold 1-8, the opening of the inverted U-shaped groove 1-10 faces downward, the groove width of the inverted U-shaped groove 1-10 is equal to the diameter of the positioning pin, to realize the horizontal positioning of each other, and the groove bottom of the inverted U-shaped groove 1-10 is in contact with the positioning pin 1-9, to realize the upward and downward positioning of each other. The positioning pin 1-9 can be a cylindrical pin, and the end of each of the two segmented molds 1-8 which are butt-jointed with each other can have the inverted U-shaped groove 1-10, and each has a mounting hole 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. In order to facilitate installation, avoid setting too many installation parts, and when switching the installation, the positioning pin 1-9 can be inverted in the longitudinal direction. And the inverted U-shaped groove 1-10 of each of the above two segmented molds 1-8 cooperates with the positioning pin 1-9 between them.

[0084] In some embodiments, as shown in the drawings, the plurality of bottom dies 1 can be arranged side by side in the lateral direction, but the bottom die 1 needs to be fixed on the foundation. In order to facilitate fixation, a gap needs to be formed between the adjacent bottom dies 1, so that there is an operating space to fix each bottom die 1 on the foundation. However, in this way, the overall land occupation space is relatively large. Based on this, it is preferred that the lateral two sides of the bottom die 1 are respectively overlapped on the support leg 4, wherein the bottom die 1 and the support leg 4 are connected through the upward and downward extending installation screw rod 5, and the dismounting operation part of the installation screw rod 5 is exposed through the window 1-2 opened on the upper side of the bottom die 1, so that the installation screw rod 5 can be operated from the window 1-2 opened on the upper side of the bottom die 1, to complete the installation between the support leg 4 and the bottom die 1, and the support leg 4 is fixed on the foundation. At this time, the bottom dies 1 can be arranged side by side and abutted. And because the upper side of the bottom die 1 needs to be arranged with the side mold device, the bottom die 1 has space to arrange the window 1-2.

[0085] In some embodiments, as shown in the drawings, specifically, the 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-shaped part formed with a first forming groove 1-1 and two ear plate parts 1-31 respectively connected to both sides of the groove-shaped part, which can also be referred to as wing plate parts.

[0086] 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-shaped structure. The sealing bottom plate 1-5 is located below the forming template 1-3 and is connected to the air cavity 7, and is provided with air holes to facilitate the introduction of steam. The support rib plate 1-4 has a support part 1-41 corresponding to the ear plate part 1-31, and the lower side of the support part 1-41 is connected to a third connecting plate 1-7. The ear plate part 1-31, the support part 1-41, the third connecting plate 1-7 and the support leg 4 are arranged in sequence from top to bottom and are aligned. The ear plate part 1-31 is provided with a window 1-2 to expose the mounting screw 5 installed on the third connecting plate 1-7. The sealing bottom plate 1-5 also has a groove-shaped structure to correspond to the first forming groove 1-1, and the bottom can be directly supported by the foundation through the support frame.

[0087] Generally, the ear plate part 1-31 has a connecting through hole 1-6 for detachable connection with the side mold part 2. The connecting through hole 1-6 and the window 1-2 can be arranged in transverse alignment to enable the side mold part 2 to cover the window 1-21. When the bottom mold 1 needs to be detached, the side mold part 2 can be removed first to expose the window 1-2, and then the mounting screw 5 can be loosened through the window 1-21 to detach the bottom mold 1.

[0088] The support leg 4 can also be provided with a longitudinal beam 6 for convenient support. The longitudinal beam 6 is fixedly connected to the connecting plate through the mounting screw 5, and the lower side of the longitudinal beam 6 is arranged with a plurality of support legs 4, which can be I-beams.
