Referring to fig. 1 to 6, the present embodiment provides a concrete pile wall mold set including two or more concrete pile wall molds 2 arranged in sequence in a transverse direction, wherein the concrete pile wall mold 2 includes: a female die assembly 21 which can be used for forming the male splicing end 11 of the concrete pile wall 1, a male die assembly 22 which can be used for forming the female splicing end 12 of the concrete pile wall 1, and a bottom die frame 23 for positioning the female die assembly 21 and the male die assembly 22; wherein the female die assembly 21 and/or the male die assembly 22 are provided with lifting parts.

As shown in fig. 7, 8 and 9, in the present embodiment, the main structure of the pile body of the formed concrete pile wall 1 is substantially rectangular, and both sides of the concrete pile wall 1 respectively have a male splicing end 11 and a female splicing end 12 adapted to the male splicing end 11 in the axial direction, the male splicing end 11 is a portion protruding relative to the surface of the concrete pile wall 1, and the female splicing end 12 is a portion recessed relative to the surface of the concrete pile wall 1, when two adjacent concrete pile walls 1 are connected, the male splicing end 11 of one concrete pile wall 1 can be clamped into the female splicing end 12 of the other concrete pile wall 1 to form an interlocking connection structure, so that two adjacent concrete pile walls 1 are clamped and fixed, and the pile wall splicing formed by connecting the concrete pile walls 1 to each other is ensured to be reliable and stable. Likewise, the male mold member 22 is a portion that is raised with respect to the inner wall of the concrete pile wall mold 2, and the female mold member 21 is a portion that is recessed with respect to the inner wall of the concrete pile wall mold 2.

As shown in fig. 1 and 2, in the present embodiment, a plurality of concrete pile wall molds 2 are arranged in sequence in the transverse direction, and in actual production, a plurality of concrete pile walls 1 can be formed in one production process, thereby improving the production efficiency.

In the structure, the female die assembly 21 is used for forming the male splicing end 11 of the concrete pile wall 1, the male die assembly 22 is used for forming the female splicing end 12 of the concrete pile wall 1, the female die assembly 21 and the male die assembly 22 are positioned through the bottom die frame 23, the female die assembly 21 and the male die assembly 22 are provided with lifting parts (not shown in the figure), after production is finished, the female die assembly 21, the male die assembly 22 and the concrete pile wall 1 are lifted together, the lifting device only needs to run for one stroke, and then workers at a die removal station remove the female die assembly 21 and the male die assembly 22, so that the production efficiency is improved.

As shown in fig. 3 and 4, in the present embodiment, the bottom mold frame 23 is a long U-shaped mold with an open top, and the female mold assembly 21 and the male mold assembly 22 are respectively disposed on two inner walls of the bottom mold frame 23.

Further, as shown in fig. 4 and 6, in order to form the female splicing end 12 of the concrete pile wall 1, in the present embodiment, the male mold assembly 22 includes at least one first mold plate 221 having a deformation resetting function and at least one second mold plate 222 having rigidity and being capable of supporting the first mold plate 221, the first mold plate 221 is at least capable of fitting an end contour of the female splicing end 12 on one side in the thickness direction of the concrete pile wall 1, the second mold plate 222 is fitted to the remaining end contour of the female splicing end 12 and at least one end can enter into or exit from the female splicing end 12, and a forming surface of the first mold plate 221 is formed at least at a predetermined distance from an end surface of the female splicing end 12 to form a protruding portion 2214 facing away from the second mold plate 222 in the thickness direction of the concrete pile wall 1.

Because the female splicing end 12 of the concrete pile wall 1 needs to be clamped with the male splicing end 11, if the forming surface of the male die assembly 22 is a hard surface, after concrete is solidified, the formed female splicing end 12 can be clamped with the male die assembly 22, the male die assembly 22 cannot be taken out of the female splicing end 12 during demolding, if a pulling mode is adopted, the male die assembly 22 is pulled out from the axial direction of the female splicing end 12, the resistance between the concrete and the male die assembly 22 is extremely large, the male die assembly 22 cannot be easily pulled out, the required operation space needs to reach twice the length of a die to be realized, the space utilization rate is reduced, and therefore, when the forming surface of the male die assembly 22 is a hard surface, the concrete pile wall with the clamping function cannot be formed.

Therefore, in this embodiment, the first mold plate 221 of the male mold assembly 22 has a deformation resetting function, when molding, the male mold assembly 22 can mold the female splicing end 12 that can be clamped with the male splicing end 11, and when demolding, since the male mold assembly 22 is clamped with the female splicing end 12 on the side of the molded concrete pile wall 1, and the first mold plate 221 of the male mold assembly 22 can be deformed under the action of external force, the male mold assembly 22 can be directly pulled out from the female splicing end 12 on the side of the concrete pile wall 1 toward the opening direction of the female splicing end 12, or the male mold assembly 22 can be pulled and deformed under the action of external force, so that the male mold assembly 22 is pulled out from the female splicing end 12 after the clamping between the male mold assembly and the female splicing end 12 fails. Therefore, the concrete pile wall 1 with the mutual engagement and clamping function can be formed through the deformation resetting function of the first template 221 of the male mold assembly 22.

In the above structure, the male mold member 22 is used to form the female splice end 12 of the concrete pile wall 1, and the first mold plate 221 is used to form the shape of each inner surface of the female splice end 12. Prior to production, first template 221 is mounted on second template 222. During demolding, the second form 222 is moved away from the concrete pile wall 1, so that the second form 222 is away from the female splicing end 12, and then the first form 221 is taken out from the female splicing end 12. In the actual production process, the first template 221 with different dimensions can be replaced according to different dimensions for production, so that the universality of the die is improved, and the cost is saved.

Specifically, the first form 221 includes a first shaping segment 2211, a second shaping segment 2212, and a third shaping segment 2213 which are consecutive in sequence, the second shaping segment 2212 is disposed substantially along the thickness direction of the concrete pile wall 1, and the second shaping segment 2212 is at least used for shaping the surface of the female splicing end 12 in the thickness direction of the concrete pile wall 1; the first shaping segment 2211 and/or the third shaping segment 2213 are arranged substantially along the width direction of the concrete pile wall 1, the first shaping segment 2211 and the third shaping segment 2213 are respectively arranged at two sides of the second shaping segment 2212, and the first shaping segment 2211 and/or the third shaping segment 2213 at least have a partial protrusion 2214 in the thickness direction of the concrete pile wall 1.

In addition, in order to achieve the deformation-resetting function of the first template 221, the first molding section 2211 and/or the second molding section 2212 and/or the third molding section 2213 are at least partially of a flexible structure or an elastic structure.

In this embodiment, the second molding segment 2212 is preferably flexible or elastic, that is, after the second mold plate 222 is removed during demolding, the first mold plate 221 is still in the female splice end 12, and only the first molding segment 2211 of the first mold plate 221 needs to be pulled downward, so that the first mold plate 221 is deformed, and the first mold plate 221 can be easily removed from the female splice end 12. Alternatively, the first shaping segment 2211 and the third shaping segment 2213 may be flexible structures or elastic structures, and at this time, after the second form 222 is removed during demolding, the first form 221 is pulled in a direction away from the concrete pile wall 1, and the protruding portions 2214 of the first shaping segment 2211 and the third shaping segment 2213 are deformed by a reaction force provided by the female splicing end 12, and can be directly pulled out. Of course, the first molding section 2211, the second molding section 2212 and the third molding section 2213 may be flexible or elastic.

In this embodiment, the second molding section 2212 is formed with at least one first arched portion 2212a protruded toward the mold cavity 24 so that the female splicing end 12 side of the formed concrete pile wall 1 forms at least one depressed surface 111. After the side of the female splicing end 12 forms the sunken surface 111, after two adjacent concrete pile walls 1 are connected, at least one filling cavity is formed between the sunken surface 111 and the female splicing end 12, and concrete can be injected into the filling cavity, so that the connection strength between the concrete pile walls 1 can be improved, and the waterproof performance between the concrete pile walls 1 can be improved.

Furthermore, in order to enable the second mold plate 222 to support the first mold plate 221, a support portion 2221 is formed on one side of the second mold plate 222 facing the mold cavity 24, the first mold plate 221 covers the support portion 2221, the outer contour shape of the support portion 2221 is approximately matched with the inner contour shape of the first mold plate 221, and the side of the support portion 2221 close to the mold cavity 24 is attached to the inner contour of the second molding section 2212. The first template 221 and the second template 222 may be fixed by one or more of fastening, clipping, adhering, and magnetic connection.

In addition, since the female mold assembly 21 and the male mold assembly 22 are both located in the bottom mold frame 23, after the production is finished, the bottom mold frame 23 does not have enough space for the male mold assembly 22 to be pulled out from the formed female splicing end 12, so that after the actual production is finished, the male mold assembly 22 needs to be lifted out of the bottom mold frame 23 together with the formed concrete pile wall 1, and then the male mold assembly 22 is removed. After the concrete pile wall 1 is formed, the friction between the male mold assembly 22 and the inner sidewall of the bottom mold frame 23 is large. Therefore, in the present embodiment, the outer side surface of the second mold plate 222 and the inner side surface of the bottom mold frame 23 are inclined outward to reduce the frictional resistance between the second mold plate 222 and the bottom mold frame 23 during demolding.

Further, as shown in fig. 4 and 5, in order to form the male splice end 11 of the concrete pile wall 1, in the present embodiment, the female mold assembly 21 includes at least two detachably connected sub-mold plates, and at least one of the sub-mold plates is formed with a concave portion 214 that fits the convex portion 2214 on the forming surface. Since the male splice end 11 needs to be engaged with the female splice end 12, the male splice end 11 has a convex portion, so that the forming surface of the sub-forms is also formed with a concave portion 214, and after forming, the male splice end 11 is locked in the forming cavity surrounded by the sub-forms, so that the sub-forms need to be detachably connected with each other in order to be disassembled.

Specifically, in the present embodiment, the master mold assembly 21 includes a first section plate 211, a second section plate 212, and a third section plate 213, the first section plate 211, the second section plate 212, and the third section plate 213 are sequentially connected to form a C-shaped cross section, and the concave portion 214 is formed on the molding surface of the first section plate 211 and/or the molding surface of the third section plate 213.

In the above structure, the first, second and third mold halves 211, 212 and 213 surround to form a molding cavity for molding the male splicing end 11 of the concrete pile wall 1. In this embodiment, the first die plate 211 is used for molding the upper surface of the male splice end 11, the second die plate 212 is used for molding the side surface of the male splice end 11, and the third die plate 213 is used for molding the lower surface of the male splice end 11. In an actual production process, the first section board 211 and the third section board 213 may be connected to the second section board 212 in advance, and then the material distribution may be performed. Of course, the third section board 213 may be connected to the second section board 212 to distribute the fabric, and then the first section board 211 may be installed. The connection mode can be combined, connected and fixed through one or more modes of fastener connection, clamping connection, adhesion and magnetic attraction connection. After production is finished, the first formwork component 211 is firstly removed, at the moment, the clamping state of the male splicing end 11 of the concrete pile wall 1 and the forming cavity can be eliminated, and the concrete pile wall 1 can be lifted out. Of course, the third section plate 213 and the second section plate 212 may be a unitary structure.

Similarly, since the female mold assembly 21 and the male mold assembly 22 are both located in the bottom mold frame 23, the bottom mold frame 23 does not have enough space for the male mold assembly 22 to be pulled out of the formed female splice end 12 after the production is finished. If the first parting plate 211 is firstly removed, then the concrete pile wall 1 and the male die assembly 22 are lifted out together, at this time, the gravity center of the concrete pile wall 1 is deviated to the male die assembly 22, the lifting process is easy to dump, and great potential safety hazards are caused, so that after the actual production is finished, the female die assembly 21 and the male die assembly 22 need to be lifted out of the bottom die frame 23 together with the formed concrete pile wall 1, and then the female die assembly 21 and the male die assembly 22 are removed. After the concrete pile wall 1 is formed, the friction between the female mold assembly and the inner side walls of the male mold assembly 22 and the bottom mold frame 23 is large, so that in order to facilitate demolding, the female mold assembly 21 and the male mold assembly 22 need to be lifted out of the bottom mold frame 23 together with the formed concrete pile wall 1, in this embodiment, preferably, the outer side surface of the second parting plate 212 and the inner side surface of the bottom mold frame 23 are inclined outward, so as to reduce the friction resistance between the second parting plate 212 and the bottom mold frame 23.

Of course, if the lateral width of the bottom mold frame 23 is sufficient, the female mold assembly 21 and the male mold assembly 22 can move in the bottom mold frame, and after production, the concrete pile wall 1 can be directly lifted by moving the female mold assembly 21 and the male mold assembly 22 respectively away from the concrete pile wall 1.

Likewise, in this embodiment, the second section plate 212 is formed with at least one second raised portion 2121 raised toward the cavity 24 so as to form at least one recessed surface 111 at the side of the male splicing end 11 of the formed concrete pile wall 1. The second arching portions 2121 correspond to the first arching portions 2212a one to one, after two adjacent concrete pile walls 1 are connected, the concave surface 111 of the female splicing end 12 and the concave surface 111 of the male splicing end 11 are matched to form a larger filling cavity, and after grouting, a waterproof effect can be better provided. Preferably, in this embodiment, an outer contour generatrix of the first and second raised portions 2212a and 2121 is a circular arc.

Furthermore, the first formwork section 211 includes a first supporting block 2111 and a first forming block 2112, a forming surface of the first forming block 2112 is used for forming one side surface of the male splicing end 11 of the concrete pile wall 1 in the thickness direction of the concrete pile wall 1, and the first supporting block 2111 and the first forming block 2112 are connected and fixed in a combination manner of one or more of fastening, clamping, bonding, and magnetic attraction. Like the first form 221 of the male mold component 22, the first forming block 2112 with different dimensions can be replaced according to different actual production requirements, so that the mold universality is improved, and the cost is saved. Preferably, the first support block 2111 and/or the first molding block 2112 have a hollow grid-like structure, so that the amount of used raw materials can be further reduced, and the cost can be saved.

Similarly, the third formwork section 213 includes a second supporting block 2131 and a second forming block 2132, a forming surface of the second forming block 2132 is used for forming the other side surface of the male splicing end 11 of the concrete pile wall 1 in the thickness direction of the concrete pile wall 1, and the second supporting block 2131 and the second forming block 2132 are connected and fixed in a combination manner by one or more of fastening, clamping, bonding and magnetic attraction. The second molding blocks 2132 with different sizes and specifications can be replaced according to different actual production requirements, the universality of the mold is improved, and the cost is saved. Preferably, the second supporting block 2131 and/or the second forming block 2132 is a hollow grid-like structure. The use amount of raw materials can be further reduced, and the cost is saved.

In addition, as shown in fig. 3, the concrete pile wall mold 2 further includes end plates 25 respectively disposed at both ends of the bottom mold frame 23, and outer contour generatrices of the end plates 25 are fitted with inner contour generatrices of the mold cavity 24. In order to improve the strength of the concrete pile wall 1 and generate prestress in the concrete pile wall 1, it is necessary to tension the rigid frame for the concrete pile wall 1, and therefore, in the present embodiment, a plurality of connection holes 251 for connection with the rigid frame for the concrete pile wall 1 are opened in the end plate 25, and a tension connection portion 252 for connection with an external tension device is provided at a central portion of at least one of the end plates 25. Wherein, the bottom die frames 23 of two adjacent concrete pile wall molds 2 are connected into a whole.

In order to save concrete cost, the concrete pile wall 1 in this embodiment may also be made hollow, so the concrete pile wall mold 2 further includes at least one core mold 26 axially disposed and used for making the formed concrete pile wall 1 hollow. In order to solve the problem of placing the core mold 26, through holes for the core mold 26 to axially penetrate are formed in the end plates 25, and the core mold 26 penetrates through the end plates 25 at both ends and abuts against the hole walls of the through holes of the end plates 25. That is, before concrete is distributed, core mold 26 is axially inserted through the through holes of end plates 25 at both ends, and the wall of the through hole is used to support core mold 26.

In addition, as shown in fig. 2, the concrete pile wall mold set further includes a mold frame 3 supporting the bottom mold frame 23, and the mold frame 3 is formed with at least one spacer 31 for positioning two adjacent bottom mold frames 23 at an interval in a transverse direction.

In the above structure, after the concrete material is distributed in the concrete pile wall mold 2, the concrete may cause extrusion forces to the female mold component 21 and the male mold component 22, thereby bringing extrusion forces to both side walls of the bottom mold frame 23, which easily causes deformation of the bottom mold frame 23. At present, in the field of prefabricated parts, steam curing, referred to as steam curing for short, is usually required to be performed on the prefabricated parts, if two adjacent bottom mold frames 23 are directly connected into a whole, when the concrete pile wall is subjected to steam curing, steam cannot enter the upper part of the concrete pile wall mold 2 through the bottom mold frames 23, and the steam curing effect is not ideal enough, so that the two adjacent bottom mold frames 23 are connected into a whole through the spacers 31, not only can the bottom mold frames 23 be supported, and the deformation of the bottom mold frames 23 is avoided, but also when the steam curing is performed, the steam can enter the upper part of the concrete pile wall mold 2 through the space between the spacers 31, and the steam curing effect is improved.

The above is only a preferred embodiment of the present invention, and the scope of the present invention is defined by the appended claims, and several modifications and amendments made by those skilled in the art without departing from the spirit and scope of the present invention should be construed as the scope of the present invention.
