DETAILED DESCRIPTION

[0029] In order for those skilled in the art to better understand the technical solutions of the present application, the present application will be further described in detail below with reference to the drawings.

[0030] As shown in Figure 1 , the embodiment provides a pier column combined prefabricated mold, which comprises a base 1 built by an I-shaped steel, a turnover table 2 is rotatably installed on the base 1 through a pin shaft, a bottom die 3 is installed on the turnover table 2 in a detachable manner, the bottom die 3 is a U-shaped and integral structure; when the bottom die 3 is in a horizontal state, the opening of the bottom die 3 faces upward. Combined side dies 4 are installed on both sides of the bottom die 3, and top dies 5 are installed between two corresponding side dies, and each top die 5 jointly forms a mold plate with the same shape and size as the bottom die 3; during installation, the bottom die 3 is first installed on the turnover table 2 through fasteners such as bolts, then the side dies 4 are installed on the bottom die 3 through fasteners such as bolts, and a steel reinforcement framework is placed in the area surrounded by the side dies 4 and the bottom die 3, and finally the top dies 5 are installed on the side dies 4 through fasteners such as bolts, thereby completing the installation of the mold plate; after the installation of the mold plate is completed, the mold is hoisted by a crane to rotate 90° to reach a vertical state. After the concrete is poured and solidified, the pier column is completed, the top dies 5 are removed first, then the bottom die 3 is removed, and finally the side dies 4 on both sides are removed.

[0031] As shown in Figure 3 , Figure 4 , Figure 5 and Figure 7 , a pull rod 6 penetrating through the side die 4 is installed on each side die 4, Figure 1The pull rod 6 is in a vertical state, the pull rod 6 is a round rod and is rotationally matched with the side mold 4, the side mold 4 is provided with a circular groove matched with the pull rod 6, the bottom mold 3 and the top mold 5 are both provided with an insertion slot 7 matched with the pull rod 6, the insertion slot 7 is in position correspondence with the circular groove and has the same inner diameter, the insertion slot 7 is fixedly provided with a stop block 8 on the inner wall, the stop block 8 includes an arc surface matched with the inner wall of the insertion slot 7 and a plane parallel to the axis of the insertion slot 7, the pull rod 6 is fixedly provided with a locking block 9 matched with the stop block 8 at the end, the locking block 9 includes a first part 901 having the same shape and size as the cross section of the stop block 8, one side of the first part 901 is flush with the circumferential surface of the pull rod 6, the pull rod 6 is further fixedly provided with a second part 902 at the end, the cross section of the second part 902 is half of the cross section of the pull rod 6 except the first part 901, the second part 902 is fixedly provided with a third part 903 at the top, the cross section of the third part 903 and the cross section of the first part 901 together form the cross section of the pull rod 6, and the distance between the third part 903 and the first part 901 is equal to the height of the stop block 8.

[0032] Specifically, during the installation process, the side mold 4 is installed on the bottom mold 3 at a predetermined position, the bottom end of the pull rod 6 is inserted into the corresponding insertion slot 7 on the bottom mold 3, the top mold 5 is installed on the side mold 4 at a predetermined position, and the top end of the pull rod 6 is inserted into the insertion slot 7 on the top mold 5. Figure 5 During splicing, the first part 901 is in position correspondence with the stop block 8 in the two insertion slots 7 and the edges are flush, so that the third part 903 can be inserted into the insertion slot 7 without being blocked by the stop block 8. Figure 5 After splicing is completed, one end of the stop block 8 is matched with the end face of the first part 901, the surface of one end of the third part 903 is matched with the inner end face of the insertion slot 7, and the surface of the other end of the stop block 8 is flush with the surface of the other end of the third part 903. Figure 5 In this state, the pull rod 6 is rotated by a certain angle (60° in this embodiment), the locking blocks 9 at both ends of the pull rod 6 are also rotated synchronously, and one end of the third part 903 is in a matched state with one end of the stop block 8.

[0033] In summary, in the pouring process of concrete, when the pressure of concrete is applied to the side mold 4, the side mold 4 transmits the pressure to the top mold 5 and the bottom mold 3 through the pull rod 6 and the locking block 9 (the pull rod 6 bears the radial pressure), thereby reducing the force acting on the fastening bolts and avoiding the occurrence of the side mold 4 explosion; when the pressure of concrete is applied to the top mold 5 and the bottom mold 3, the cooperation of the locking block 9 and the stop block 8 makes the pull rod 6 and the locking block 9 share a part of the pressure (the pull rod 6 bears the axial pressure), thereby reducing the force acting on the fastening bolts and avoiding the occurrence of the top mold 5 and the bottom mold 3 explosion. In the embodiment, the pull rod 6 does not contact the concrete, and the pull rod does not need to be taken out from the concrete after the concrete solidifies, which improves the convenience of operation and avoids the adverse effect on the structural strength of the pier column as a whole.

[0034] As shown in Figure 3 and Figure 4 , the side mold 4 is provided with an opening communicating with a circular groove on the outer wall, and the control plate 10 is installed on the side wall of the pull rod 6 corresponding to the position of the opening; when the control plate 10 is attached to one side of the opening, the pull rod 6 is in the first state; after the pull rod 6 is rotated by 60°, the control plate 10 is attached to the other side of the opening, and at this time, the pull rod 6 is in the second state; the width of the control plate 10 is the same as the width of the opening. In this way, the construction personnel only need to rotate the control plate 10 to adjust the state of the pull rod 6 and the locking block 9, and the pull rod 6 can be stably maintained in the first state during installation, thereby ensuring that the locking block 9 is accurately inserted into the insertion slot 7 and will not be blocked by the stop block 8. After the installation is completed, the control plate 10 is pushed to be attached to the other side of the opening, thereby accurately adjusting the rotation angle of the pull rod 6 and the locking block 9, and then the locking block 9 can be accurately adjusted to the state of cooperating with the stop block 8, thereby limiting the top mold 5 and the bottom mold 3, and avoiding the mold explosion.

[0035] As shown in Figure 2 , Figure 3 , Figure 4 and Figure 8 , the control plate 10 is provided with a strip-shaped slot 11 on one side, and the control plate 10 on the same side is jointly provided with a limiting rod 12 cooperating with the strip-shaped slot 11, and the limiting rod 12 can be separated from the control plate 10; the overturning table 2 is provided with a socket 201 cooperating with the limiting rod 12, and the socket 201 is rectangular. The side wall of the pull rod 6 is provided with a square groove 601, and the edge of the control plate 10 forms a square protrusion 13 cooperating with the square groove 601. When the pull rod 6 is in the first state (solid line state in Figure 8 ), the limiting rod 12 can be inserted into each control plate 10 on the same side from the strip-shaped slot 11, thereby limiting the control plate 10; when the pull rod 6 is in the second state (dashed line state in Figure 8When the template is in the horizontal state (indicated by the dashed line), the limiting rods 12 can also be inserted into the strip-shaped grooves 11 of the control plates 10 on the same side, thereby limiting the control plates 10; in this way, the limiting rods 12 can limit the control plates 10 and the pull rod 6.

[0036] Specifically, before the template is installed, the pull rod 6 is in the first state, and after the top mold 5, the bottom mold 3, and the side mold 4 are all installed, the control plate 10 is pushed to make the pull rod 6 rotate 60° into the second state, then the limiting rod 12 is inserted into the strip-shaped groove 11 of each control plate 10 to limit each control plate 10, that is, the control plate 10 and the pull rod 6 cannot rotate, and finally the limiting rod 12 is translated along the length direction of the limiting rod 12, and one end of the limiting rod 12 is inserted into the socket 201. It should be noted that after the template is turned to the vertical state, the lower top mold 5 and side mold 4 bear a larger pressure during the concrete pouring process, and the upper top mold 5 and side mold 4 bear a smaller pressure during the concrete pouring process, in order to avoid the deformation of the partial top mold 5 and side mold 4 due to the long-term large pressure, the positions of the top mold 5 and side mold 4 need to be symmetrically exchanged between two adjacent pouring processes, and the originally lowest top mold 5 and side mold 4 need to be exchanged to the uppermost position in the vertical state of the template.

[0037] As Figure 3As shown, the position corresponding to each control plate 10 on the limiting rod 12 is fixedly installed with a lifting plate 14 matched with the surface of the control plate 10, and the lifting plate 14 is fixedly installed with a limiting plate 15 matched with both ends of the control plate 10, and the limiting plate 15 is L-shaped. After the pier column is solidified, the construction personnel first disassemble each fastening bolt, then translate the limiting rod 12, so that the limiting rod 12 is separated from the control plate 10, the limiting of the control plate 10 is released, the control plate 10 is pushed, the control plate 10 is adjusted to the initial state, the limiting rod 12 is inserted into the strip-shaped slot 11, the limiting rod 12 is used for limiting each control plate 10, and the pull rod 6 and the control plate 10 cannot rotate. In this state, the bottom die 3 and each top die 5 are first translated, and the bottom die 3 and the top die 5 are disassembled. Then the side die 4 is disassembled, and the side die 4 on the same side can be disassembled integrally, and the specific steps are as follows: the limiting rod 12 is first pulled upward, so that the bottom end of the limiting rod 12 is separated from the socket 201, the upper surface of the lifting plate 14 is in close contact with the lower surface of the corresponding control plate 10, and the limiting plate 15 is in close contact with the side surface of the control plate 10. In this state, the limiting rod 12 can be translated by the crane, so that all the side dies 4 on the same side are separated from the pier column, then the two ends of the limiting rod 12 are suspended by the crane, the limiting rod 12 and the side die 4 are further rotated by 90° along the overturning direction, and the integral disassembly process of the side die 4 is completed; during the rotation process, the lifting plate 14 and the limiting plate 15 always support the control plate 10, so that the side die 4 can be stably overturned by 90°. Before manufacturing the next pier column, the limiting rod 12 is translated along the length direction, so that the lifting plate 14 and the limiting plate 15 are separated from the control plate 10, then the limiting rod 12 is disassembled, so that the limiting rod 12 is separated from the control plate 10, then the control plate 10 is pulled out, is adjusted by 180° and is reinserted into the square slot 601, and the purpose is to adjust the opening of the strip-shaped slot 11 from the downward state to the upward state; finally, the limiting rod 12 is reinserted into the strip-shaped slot 11, the limiting rod 12 is translated along the length direction, so that the lifting plate 14 and the limiting plate 15 are in close contact with the control plate 10, in this way, the limiting rod 12 can be directly used for integrally installing each side die 4 on the same side by suspending the limiting rod 12 when the next pier column is manufactured. As described above, the limiting rod 12 in the embodiment not only plays a role in limiting the control plate 10, but also realizes the integral disassembly and installation of the side die 4 on the same side by cooperating with the control plate 10, and the operation convenience is improved.

[0038] The above only describes certain exemplary embodiments of the application in a descriptive manner, and it is needless to say that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the application. Therefore, the above drawings and descriptions are illustrative in nature and should not be understood as limiting the scope of protection of the claims of the application.
