Description

Technical Field

[0001] This utility model relates to the field of construction mold technology, and in particular to a construction mold for water conservancy and municipal engineering projects. Background Technology

[0002] Construction molds are temporary or permanent structures used in water conservancy and municipal engineering projects to shape concrete or other building materials, ensuring that components are formed according to design requirements and meet strength, dimensional, and appearance requirements. In water conservancy projects, molds are commonly used for the construction of structures such as channels, pipelines, retaining walls, gates, and inspection wells; in municipal engineering projects, they are used for pipe galleries, curbs, drainage ditches, and box culverts.

[0003] As disclosed in CN215562305U, this utility model discloses a mold for water conservancy engineering construction, including two fixed steel plates. An adjustment mechanism is provided on one side of each fixed steel plate, and two moving mechanisms are provided between the two fixed steel plates to change the size of the molded material. This utility model forms a cement and concrete pouring cavity through the cooperation of the two fixed steel plates and the two moving steel plates. The position of the two moving steel plates is adjusted by the adjustment mechanism, which changes the distance between the two moving steel plates, thereby changing the shape and size of the poured cement and concrete. Through the cooperation of these mechanisms, the problem of cumbersome molding process and poor molding effect in existing water conservancy engineering construction molds for molding cement and concrete is solved.

[0004] However, in the existing technology, workers turn the handle to move the lead screw, which in turn moves the moving plates closer together to adjust the size of the concrete to be poured. Then, the concrete is poured into the area formed by the steel plate, and the surface is smoothed with tools to shape it. However, during the pouring process, air bubbles are easily generated when the concrete accumulates in the shaping frame. After shaping, these air bubbles will cause honeycomb-like structures inside the concrete, affecting the quality of the concrete. On the other hand, after shaping, workers have to knock to separate the steel plate from the concrete, and the entire frame needs to be moved before the concrete blocks can be moved. The whole process is both time-consuming and labor-intensive. Utility Model Content

[0005] The purpose of this invention is to solve the problems in the prior art where, during the pouring of concrete, air bubbles are easily generated when the concrete accumulates in the molding frame. After molding, these air bubbles will cause honeycomb-like structures inside the concrete, affecting the quality of the concrete. On the other hand, after molding, workers have to knock to separate the steel plate from the concrete and move the entire frame before they can move the concrete blocks. The whole process is both time-consuming and labor-intensive.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a construction mold for water conservancy and municipal engineering, comprising a support platform, a shaping structure at the top of the support platform, the shaping structure comprising a shaping component and an adjusting component, pressing components on both sides of one end of the support platform, a groove in the middle of the bottom end of the support platform, a striking component inside the groove, and a vibrating plate fixedly connected to the top of the support platform.

[0007] In a preferred embodiment, the adjustment assembly includes a bracket, which is fixed to one side of the top of the support platform. A first motor is provided at the top of the bracket, and a lead screw is driven to the bottom of the first motor. The lead screw rotates through the bracket and is rotatably connected to the support platform at its bottom.

[0008] In a preferred embodiment, the shaping component includes a shaping frame placed on the top of a support platform away from the side of the bracket. A movable plate is slidably connected inside the shaping frame, and the bottom end of the movable plate is slidably connected to the support platform. An electric actuator is fixedly connected to the top of the movable plate near the bracket, and a support ring is fixedly connected to the middle of the electric actuator. The bottom end of the support ring is fixedly connected to the shaping frame.

[0009] In a preferred embodiment, a lifting plate and a limiting plate are fixedly connected to the bottom end of the molding frame near the support. The lifting plate is located in the middle of the limiting plate and is threadedly connected to the lead screw. Both the limiting plate and the lifting plate are slidably connected to the support.

[0010] In a preferred embodiment, the pressing assembly includes a fixing column, which is fixed to the side of the molding frame away from the support. A fixing shaft is fixedly connected to the top of the fixing column, and a rotating plate is rotatably connected to the top of the fixing shaft. A fixing rod is fixedly connected to the bottom of the rotating plate on the side away from the fixing shaft, and a pressing plate is fixedly connected to the bottom of the fixing rod.

[0011] In a preferred embodiment, the striking assembly includes a second motor, which is fixed to one side inside the groove. One end of the second motor is connected to a rotating rod, and the end of the rotating rod away from the second motor is rotatably connected. Striking wheels are fixedly arranged at equal intervals in the middle of the rotating rod, and the striking wheels abut against the vibrating plate.

[0012] The beneficial effects of this utility model are as follows:

[0013] In this invention, workers pour concrete into the inside of the plastic frame, start the second motor to drive the rotating rod to rotate, the rotating rod drives the striking wheel to rotate, the striking wheel rotates to strike the vibrating plate, the vibrating plate drives the concrete at the top to vibrate, and the concrete vibration causes the internal air to be discharged, thereby avoiding the honeycomb structure of the concrete after solidification and improving the quality of the concrete block.

[0014] After the concrete hardens, the rotating plate is deflected, causing it to rotate laterally and align with each other. The lower pressure plate is positioned at the top of the concrete with a slight gap between them. Then, the first motor is activated, driving the lead screw to rotate. The lead screw drives the lifting plate to rise, which in turn drives the shaping frame and the moving plate to rise. Simultaneously, the electric actuator drives the moving plate to retract, and the moving plate gradually separates from the concrete under pressure. As the shaping frame rises, it causes the concrete to rise slightly, eventually contacting the lower pressure plate. The lower pressure plate compresses the concrete, while the shaping frame continues to rise, ultimately causing the concrete to detach from the shaping frame. Once the shaping frame and concrete are completely separated, the workers can remove the concrete from the support platform without having to move the entire frame. Attached Figure Description

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1 and Figure 2 This utility model provides a technical solution: a construction mold for water conservancy and municipal engineering, including a support platform 1, a shaping structure at the top of the support platform 1, the shaping structure including a shaping component and an adjusting component, pressing components on both sides of one end of the support platform 1, a groove 11 in the middle of the bottom end of the support platform 1, a striking component inside the groove 11, and a vibrating plate 12 fixedly connected to the top of the support platform 1.

[0024] like Figure 1 - Figure 5 As shown, the adjustment assembly includes a bracket 21, which is fixed to one side of the top of the support platform 1. A first motor 211 is installed at the top of the bracket 21, and a lead screw 212 is driven to the bottom of the first motor 211. The lead screw 212 rotates through the bracket 21 and is rotatably connected to the support platform 1. The shaping assembly includes a shaping frame 22, which is placed on the top of the support platform 1 away from the bracket 21. A movable plate 221 is slidably connected inside the shaping frame 22, and the bottom of the movable plate 221 is slidably connected to the support platform 1. An electric push rod 222 is fixedly connected to the top of the movable plate 221 near the bracket 21. A support ring 223 is fixed in the middle of the electric push rod 222. The bottom end of the frame is fixedly connected to the shaping frame 22. The bottom end of the shaping frame 22 near the support 21 is fixedly connected to the lifting plate 224 and the limiting plate 225. The lifting plate 225 is located in the middle of the limiting plate 225, and the lifting plate 224 is threadedly connected to the lead screw 212. The limiting plate 225 and the lifting plate 224 are slidably connected to the support 21. The pressing component includes a fixing column 31. The fixing column 31 is fixed on the side of the shaping frame 22 away from the support 21. The top end of the fixing column 31 is fixedly connected to the fixing shaft 32. The top end of the fixing shaft 32 is rotatably connected to the rotating plate 33. The bottom end of the rotating plate 33 away from the fixing shaft 32 is fixedly connected to the fixing rod 34. The bottom end of the fixing rod 34 is fixedly connected to the pressing plate 35.

[0025] like Figure 1 and Figure 2As shown, the striking assembly includes a second motor 41, which is fixed to one side inside the groove 11. One end of the second motor 41 is connected to a rotating rod 42, and the end of the rotating rod 42 away from the second motor 41 is rotatably connected. Striking wheels 43 are fixedly arranged at equal intervals in the middle of the rotating rod 42 and abut against the vibrating plate 12.

[0026] In this embodiment, the operator activates the electric actuator 222 according to the required size of the shaped concrete. The electric actuator 222 pushes the moving plate 221 to move inside the shaping frame 22, so that the side of the moving plate 221 away from the support 21 forms a shaping area. Then, concrete is poured into the interior of the shaping frame 22. After the concrete solidifies, the rotating plate 33 is deflected, and the rotating plate 33 rotates laterally to align with each other. The lower pressure plate 35 is located at the top of the concrete with a small gap between them. Then, the first motor 211 is activated to drive the lead screw 212 to rotate, and the lead screw 212 drives the lifting plate. As the lifting plate 224 rises, it drives the shaping frame 22 and the moving plate 221 to rise. At the same time, the electric actuator 222 drives the moving plate 221 to retract, and the moving plate 221 gradually separates from the concrete under force. When the shaping frame 22 rises, it will cause the concrete to rise slightly and then come into contact with the lower pressure plate 35. The lower pressure plate 35 squeezes the concrete, while the shaping frame 22 continues to rise, eventually causing the concrete to detach from the shaping frame 22. When the shaping frame 22 and the concrete are completely separated, the workers can remove the concrete from the support platform 1 without having to move the entire frame.

[0027] In this embodiment, the worker pours concrete into the interior of the plastic frame 22, starts the second motor 41 to drive the rotating rod 42 to rotate, the rotating rod 42 drives the striking wheel 43 to rotate, the striking wheel 43 rotates and strikes the vibrating plate 12, the vibrating plate 12 drives the concrete at the top to vibrate, and the vibration of the concrete causes the internal gas to be discharged, thereby avoiding the honeycomb structure of the concrete after solidification and improving the quality of the concrete block.

[0028] Working principle: First, the operator activates the electric actuator 222 according to the required size of the shaped concrete. The electric actuator 222 pushes the moving plate 221 to move inside the shaping frame 22, so that the side of the moving plate 221 away from the support 21 forms the shaping area. Then, the concrete is poured into the interior of the shaping frame 22. The second motor 41 is started to drive the rotating rod 42 to rotate. The rotating rod 42 drives the striking wheel 43 to rotate. The striking wheel 43 strikes the vibrating plate 12, causing the concrete at the top to vibrate. The vibration of the concrete causes the internal air to be discharged, thereby preventing honeycomb-like structures from appearing in the concrete after solidification and improving the quality of the concrete block. After the concrete solidifies, the rotating plate 33 is deflected, and the rotating plate 33 rotates laterally to align with each other and presses down. Plate 35 is located at the top of the concrete with a small gap between them. Then, the first motor 211 is started to drive the lead screw 212 to rotate. The lead screw 212 drives the lifting plate 224 to rise. The lifting plate 224 drives the shaping frame 22 and the moving plate 221 to rise. At the same time, the electric push rod 222 drives the moving plate 221 to retract. The moving plate 221 is gradually separated from the concrete under force. When the shaping frame 22 rises, it will cause the concrete to rise slightly and then come into contact with the lower pressure plate 35. The lower pressure plate 35 squeezes the concrete, while the shaping frame 22 continues to rise, eventually causing the concrete to detach from the shaping frame 22. When the shaping frame 22 is completely separated from the concrete, the workers can remove the concrete from the support platform 1 without having to move the entire frame.
