Description

Technical Field

[0001] This invention relates to the field of mold technology, and in particular to a twisted block template. Background Technology

[0002] Twisted king blocks are a type of revetment block, commonly used in hydraulic engineering projects such as breakwaters, revetments, sand-blocking dikes, and diversion dikes. They are generally placed on the outermost layer of the dike to protect the dike by weakening the impact of waves. They are made of concrete and are cast in one go using precast templates.

[0003] When using existing twisted block formwork, traditional right-angle formwork has problems such as stress concentration, inconvenient construction, and large formwork wear. In addition, some finished twisted blocks have bubbles, honeycomb, and pitting on the surface, which leads to a decline in the quality of finished twisted blocks and a high scrap rate. Summary of the Invention

[0004] The purpose of this invention is to solve the problems existing in the prior art and to propose a twisted king character block template.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A Twisted King-shaped block template includes a template body, which includes two movable abutting half-template members. Fasteners are provided between the two half-template members. From top to bottom, each half-template member is provided with an upper limb mold shell, a middle limb mold shell, and a lower limb mold shell. The middle limb mold shell, the upper limb mold shell, and the lower limb mold shell are interconnected. The two half-template members together form a casting cavity for casting the Twisted King-shaped block. An opening is provided at the top of the upper limb mold shell. Guide plates are provided at the corners of the upper limb mold shell, the middle limb mold shell, and the lower limb mold shell. A vibration component for driving the displacement of the guide plates is provided on the middle limb mold shell.

[0007] Preferably, reinforcing plates are provided on the outer sides of the upper limb mold shell, the middle limb mold shell, and the lower limb mold shell. The reinforcing plates include longitudinal ribs and transverse ribs that are perpendicular to and intersecting the longitudinal ribs.

[0008] Preferably, a first reinforcing rod is provided between the upper limb mold shell and the lower limb mold shell, and a second reinforcing rod is provided between the middle limb mold shell and the lower limb mold shell.

[0009] Preferably, the fastener includes connecting plates respectively disposed on the two half-template pieces, the two connecting plates being movable against each other, one of the connecting plates being provided with a fastening bolt, and the other connecting plate being provided with a mounting hole that mates with the fastening bolt.

[0010] Preferably, one of the connecting plates is fixed with a protrusion, and the other connecting plate is provided with a groove that matches the protrusion. A sealing gasket is provided in the groove, and the sealing gasket is made of EPDM rubber.

[0011] Preferably, the vibration assembly includes a drive motor fixed to the middle limb mold shell by a support, the output shaft of the drive motor is connected to a reciprocating lead screw, a sleeve is threaded onto the reciprocating lead screw, and a pushing part is provided on the sleeve for driving the guide plate on the middle limb mold shell to move.

[0012] Preferably, the pushing part includes an annular frame fixedly connected to the sleeve by a connecting rod, a fixed rod evenly arranged on the annular frame in a circular pattern, and a swing rod movably arranged between the fixed rod and the guide plate. The middle limb mold shell is fixedly provided with a shell at the corner, and the guide plate is slidably connected in the shell.

[0013] Preferably, the guide plate is either a rounded corner plate or a chamfered corner plate, and the semi-template component is made of low-alloy high-strength structural steel.

[0014] Preferably, a rotating rod is fixed at the end of the reciprocating screw away from the drive motor. A spiral guide groove is provided on the rotating rod. A sleeve is fitted on the outer side of the rotating rod. A positioning block that cooperates with the spiral guide groove is fixed on the inner wall of the sleeve. An L-shaped plate is fixed at the end of the sleeve away from the middle limb mold shell. The L-shaped plates connected at the bottom of the two half mold pieces are inserted into each other. The bottom of the lower limb mold shell is provided with rollers that are slidably connected to the L-shaped plates through a support.

[0015] Preferably, one of the L-shaped plates is provided with an insert block, and the other L-shaped plate is provided with a slot that mates with the insert block. The L-shaped plate is threaded with a second bolt that mates with the insert block.

[0016] Compared with the prior art, the present invention provides a twisted king-shaped block template, which has the following characteristics:

[0017] Beneficial effects:

[0018] 1. This twisted block formwork, by setting up guide plates to guide the flow direction of concrete, achieves uniform stress distribution, which can solve the drawbacks of traditional formwork, significantly reduce the defect rate of blocks, advance the construction progress, save project costs, and effectively improve the overall benefits of the project. It has good promotion and application value and optimization potential.

[0019] 2. The Twisted King Block formwork uses a vibration assembly to reciprocate the guide plate inside the middle leg mold shell, allowing the concrete to flow fully in the pouring cavity. This eliminates air bubbles in the concrete, preventing surface defects such as air bubbles and sand spots from appearing on the finished product, and improving the one-time casting pass rate of the precast Twisted King Blocks.

[0020] 3. The Twisted King Block template rotates by rotating a rotating rod when the reciprocating screw rotates. The spiral guide groove on the rotating rod, together with the positioning block in the sleeve, enables the template body to move back and forth relative to the L-shaped plate. This causes the concrete in the pouring cavity to shake, ensuring that the concrete fully fills every area of ​​the pouring cavity. This further avoids surface quality defects such as air bubbles and sand spots on the surface of the finished product after pouring, and improves the one-time casting qualification rate of the precast Twisted King Block.

[0031] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0032] like Figures 1 to 4 As shown, this embodiment proposes a Twisted King block template, including a template body, which includes two movable abutting half template parts 1. Fasteners 7 are provided between the two half template parts 1. The half template parts 1 are provided with an upper limb mold shell 101, a middle limb mold shell 102 and a lower limb mold shell 103 from top to bottom. The middle limb mold shell 102, the upper limb mold shell 101 and the lower limb mold shell 103 are interconnected. The two half template parts 1 enclose to form a casting cavity for casting the Twisted King block. An opening is provided at the top of the upper limb mold shell 101. Guide plates 2 are provided at the corners of the upper limb mold shell 101, the middle limb mold shell 102 and the lower limb mold shell 103. Among them, a vibration component for driving the displacement of the guide plate 2 is provided on the middle limb mold shell 102.

[0033] Furthermore, the fastener 7 includes connecting plates 701 respectively disposed on the two half template parts 1, the two connecting plates 701 being movable abutting each other, one connecting plate 701 being provided with a fastening bolt 702, and the other connecting plate 701 being provided with a mounting hole 703 that mates with the fastening bolt 702.

[0034] Furthermore, the guide plate 2 is either a rounded corner plate or a chamfered corner plate, and the semi-template component 1 is made of low alloy high-strength structural steel;

[0035] Two half-formwork pieces 1 are aligned and locked along the vertical joint using fasteners 7. Fastening bolts 702 are used to position and lock the connecting plates 701 on the two half-formwork pieces 1, forming a complete pouring cavity. The opening at the top of the upper limb formwork 101 serves as the concrete pouring port. The connecting structure between the middle limb formwork 102 and the lower limb formwork 103 ensures smooth grout flow. The vibration component built into the middle limb formwork 102 drives the guide plate 2 to periodically displace through mechanical transmission. The guide plate 2 adopts a rounded or chamfered design to create dynamic disturbance at the corners, eliminating air bubbles at the corners of the middle limb formwork 102. The rounded corner design disperses stress through a smooth transition, while the chamfered design changes the direction of concrete flow to achieve uniform stress distribution, thereby reducing the occurrence of air bubbles, honeycomb, and pitting on the surface of the finished twisted block and improving the quality of the finished twisted block.

[0036] like Figure 1 , Figure 2 and Figure 3 As shown, in a preferred embodiment, based on the above method, further, reinforcing plates are provided on the outer sides of the upper limb mold shell 101, the middle limb mold shell 102, and the lower limb mold shell 103. The reinforcing plates include longitudinal ribs 3 and transverse ribs 4 that are perpendicular to the longitudinal ribs 3. A first reinforcing rod 5 is provided between the upper limb mold shell 101 and the lower limb mold shell 103, and a second reinforcing rod 6 is provided between the middle limb mold shell 102 and the lower limb mold shell 103. The setting of ribs and reinforcing rods facilitates the improvement of the overall rigidity of the mold and forms a stable anti-torsional system.

[0037] like Figure 4 As shown, in a preferred embodiment, based on the above method, one of the connecting plates 701 is further provided with a protrusion 7011, and the other connecting plate 701 is provided with a groove 7012 that matches the protrusion 7011. A sealing gasket 7013 is provided in the groove 7012. The sealing gasket 7013 is made of EPDM rubber. When the two half-template pieces 1 are attached, the protrusion 7011 matches and aligns with the groove 7012, and the protrusion 7011 squeezes the sealing gasket 7013. The sealing gasket 7013 deforms and fills the gap between the two half-template pieces 1 to prevent grout leakage.

[0038] like Figure 1 , Figure 2 and Figure 5 As shown, in a preferred embodiment, based on the above method, the vibration assembly further includes a drive motor 8 fixed on the middle limb mold shell 102 by a support. The output shaft of the drive motor 8 is connected to a reciprocating lead screw 801. A sleeve 802 is threaded onto the reciprocating lead screw 801. A pushing part for driving the guide plate 2 on the middle limb mold shell 102 to move is provided on the sleeve 802.

[0039] Furthermore, the pushing part includes an annular frame 9 fixedly connected to the sleeve 802 via a connecting rod, a fixed rod 901 evenly arranged on the annular frame 9 in a circular pattern, and a swing rod 902 movably arranged between the fixed rod 901 and the guide plate 2. The middle limb mold shell 102 is fixedly provided with a shell 10 at the corner, and the guide plate 2 is slidably connected in the shell 10.

[0040] Specifically, when the vibration assembly is working, the drive motor 8 drives the reciprocating screw 801 to rotate, and the sleeve 802 moves back and forth along the axial direction of the reciprocating screw 801. When the sleeve 802 moves, it drives the ring frame 9 to move through the connecting rod, so that the ring frame 9 drives the swing rod 902 to move through the fixed rod 901. The swing rod 902 drives the guide plate 2 to move back and forth in the shell 10, thereby pushing the concrete at the inside corner of the middle leg mold shell 102 back and forth, so that the concrete flows fully in the pouring cavity, so that the air bubbles in the concrete in the pouring cavity are fully eliminated, avoiding the appearance quality defects such as air bubbles and sand spots on the surface of the finished product after pouring, and improving the one-time pouring qualification rate of the precast twisted block.

[0041] like Figure 1 , Figure 2 and Figure 5 As shown, in a preferred embodiment, based on the above method, a rotating rod 11 is fixedly provided at the end of the reciprocating screw 801 away from the drive motor 8. A spiral guide groove 111 is provided on the rotating rod 11. A sleeve 12 is sleeved on the outside of the rotating rod 11. A positioning block 121 that cooperates with the spiral guide groove 111 is fixedly provided on the inner wall of the sleeve 12. An L-shaped plate 13 is fixedly provided at the end of the sleeve 12 away from the middle limb mold shell 102. The L-shaped plates 13 connected at the bottom of the two half mold pieces 1 are inserted into each other. A roller 14 that is slidably connected to the L-shaped plate 13 is provided at the bottom of the lower limb mold shell 103 through a support.

[0042] Specifically, when the reciprocating screw 801 rotates, it drives the rotating rod 11 to rotate. The spiral guide groove 111 on the rotating rod 11, together with the positioning block 121 in the sleeve 12, enables the template body to move back and forth relative to the L-shaped plate 13, thereby causing the concrete in the pouring cavity to shake, so that the concrete fully fills every area of ​​the pouring cavity, further avoiding surface quality defects such as bubbles and sand spots on the surface of the finished product after pouring, and improving the one-time pouring qualification rate of the precast twisted block.

[0043] like Figure 1 , Figure 2 and Figure 6 As shown, in a preferred embodiment, based on the above method, one of the L-shaped plates 13 is provided with a plug 131, and the other L-shaped plate 13 is provided with a slot 132 that cooperates with the plug 131. The L-shaped plate 13 is threaded with a second bolt 133 that cooperates with the plug 131.

[0044] Specifically, by disassembling the two L-shaped plates 13, it is convenient to move the L-shaped plates 13 along their respective connected half-formwork pieces 1 after the formwork has been poured and shaped into concrete, so that the two half-formwork pieces 1 can be separated and the twisted block can be removed. Depending on the actual use, pulleys can be installed on the bottom side of the L-shaped plates 13 to facilitate their movement.

[0045] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
