Description

Technical Field

[0001] This invention belongs to the field of building construction technology, specifically relating to a special CNC template device for automated forming of post-cast walls and columns. Background Technology

[0002] When pouring concrete for a second time, the presence of structural beams or floor slabs at the top of the column restricts the operational space between the top of the concrete column and the structural beams, making it difficult to effectively pour concrete into the space between them. The current common practice is to set a protruding, funnel-shaped pouring opening on the top of one side of the formwork to facilitate concrete pouring. After the concrete is poured, the excess concrete is then removed. However, this method requires removing excess concrete from the column surface later, which wastes materials, is costly, involves complicated procedures, slows down construction, and results in poor surface quality.

[0003] To address the aforementioned issues, for example, a Chinese patent discloses a diversion and pouring tool for structural columns (patent publication number: CN104790668A), comprising two opposing side plates, a rotating shaft, two stops, and a diversion plate. The two stops are respectively located on opposite sides of the two side plates, and the diversion plate is located between the two side plates. The lateral dimension of the diversion plate corresponds to the distance between the two side plates. The lower end of the diversion plate is fixedly connected to the rotating shaft so that it can rotate with the rotation of the rotating shaft. The two stops are located at the upper ends of the two side plates and are in the outer position when the diversion plate is in a vertical state. The two stops are used to abut against the outer surface of the diversion plate so that the upper end of the diversion plate is inclined outward. After pouring concrete, there is no need to chisel the protruding concrete, ensuring one-time molding, which can greatly save the construction cost of structural column pouring and improve work efficiency.

[0004] While the above technical solution solves the current problems of inconvenient pouring of concrete between structural columns and main structural beams, and the need for finishing after pouring, it still requires constant monitoring of the concrete volume during the pouring process. This is because when the concrete is poured between the drainage plate and the side plates, some concrete will overflow into the space between the drainage plate and the side plates (in conjunction with...). Figure 3 As shown in the figure, if too much concrete is poured, when the diversion plate is rotated, the concrete between the diversion plate and the two side plates will not only overflow, but will also block the rotation of the diversion plate. If too little concrete is poured, it will not be able to completely fill the gaps inside, which will affect subsequent construction and lead to safety hazards in construction quality. Summary of the Invention

[0005] In view of this, the purpose of the present invention is to provide a special CNC template device for automated forming of post-cast wall columns, so as to solve the problem that the calculation of the pouring volume is inaccurate when pouring concrete for the second time between the existing structural columns and structural beams, resulting in gaps or excessive chiseling when the structural columns are piled.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A CNC template device for automated molding of post-cast wall columns is installed at the pouring opening formed between the structural column and the beam. It includes a horizontally positioned fixed plate and two side plates vertically positioned on the upper surface of the fixed plate. The device is characterized in that: the fixed plate is flush with the lower end face of the pouring opening; the two side plates are spaced apart on both sides of the pouring opening, and a guide plate is movably positioned between the two side plates; the two side surfaces of the guide plate abut against the surfaces of the adjacent side plates; the guide plate is rotatably connected to the two side plates, and when the guide plate rotates towards the pouring opening to a vertical position, one side surface of the guide plate abuts against and covers the pouring opening; the guide plate is connected to a driving component that drives its rotation; the driving component is mounted on the fixed plate; a distance detection mechanism is installed on the surface of each side plate to detect the distance between the liquid level of the concrete and the surface of the baffle between the two side plates and the baffle.

[0008] Furthermore, a vibration assembly is installed on the surface of the diversion plate away from the pouring port; the vibration assembly includes a movable block that is horizontally slidably disposed on the surface of the diversion plate and a drive motor that drives the movable block to reciprocate in the horizontal direction; the drive motor is fixed on the surface of the diversion plate, and the movable block is mounted on the surface of the diversion plate; each end of the movable block is provided with an abutment block; the two abutment blocks are vertically fixed on the surface of the diversion plate, and when the drive motor drives the movable block to reciprocate, the two ends of the movable block intermittently abut against the corresponding abutment blocks.

[0009] Furthermore, the two side plates are slidably disposed on the upper surface of the fixed plate in a horizontal direction; movable plates are elastically slidably disposed on the surfaces of the drainage plate that abut against the two side plates; one end of each of the movable plates abuts against the corresponding side plate surface; a horizontally disposed distance sensor is installed on the surface of any side plate, and the detection end of the distance sensor faces the surface of the other side plate; the distance sensor is electrically connected to the controller.

[0010] Furthermore, buffer blocks are elastically inserted into the two side surfaces of the movable block facing the two abutting blocks.

[0011] Furthermore, multiple pressure sensors are installed on the surface of the diversion plate near the pouring port, and the multiple pressure sensors are spaced apart in the vertical direction; all the pressure sensors are electrically connected to the controller.

[0012] Furthermore, an adjustable telescopic rod is hinged to the lower surface of the fixed plate, and a base plate is hinged to the end of the telescopic rod away from the fixed plate; the base plate is placed on the ground.

[0013] The beneficial effects of this invention are as follows:

[0014] 1. This invention, through the cooperation of a fixed plate, a diversion plate, side plates, a driving component, a controller, and a distance detection mechanism, can continuously monitor the liquid level of the concrete between the two side plates and the diversion plate. The controller can automatically calculate the position where the concrete should be poured onto the surface of the diversion plate, so that after the diversion plate closes the pouring opening, the concrete on the upper surface of the diversion plate can precisely fill the gap at the pouring opening. This improves the degree of automation, eliminates the need for workers to constantly monitor the concrete pouring onto the diversion plate, and improves work efficiency.

[0025] like Figures 1-6 As shown,

[0026] A CNC template device for automated molding of post-cast wall columns is installed at the pouring opening 3 formed between the structural column 1 and the beam 2. It includes a horizontally positioned fixing plate 4 and two vertically positioned side plates 5 on the upper surface of the fixing plate 4. The fixing plate 4 abuts against the surface of the structural column 1, and its upper surface is flush with the lower end face of the pouring opening 3. The two side plates 5 are spaced apart on both sides of the pouring opening 3, and a flow guide plate 6 is movably positioned between the two side plates 5. The two side surfaces of the flow guide plate 6 abut against the surfaces of the adjacent side plates 5. The flow guide plate 6 is rotatably connected to the two side plates 5, and when the flow guide plate 6 rotates towards the pouring opening 3 to a vertical position, one side surface of the flow guide plate 6 abuts against and covers the pouring opening 3. Plate 6 is connected to an electric telescopic rod 7 (driving component) that drives its rotation; the surface of the fixed plate 4 has a notch, the electric telescopic rod 7 is disposed in the notch and rotatably connected to the fixed plate 4, and the output end of the electric telescopic rod 7 is hinged to the surface of the diversion plate 6; an ultrasonic liquid level sensor 8 (liquid level distance sensor) for detecting the height of the concrete horizontal plane between the two side plates 5 is installed on the surface of any of the side plates 5; the ultrasonic liquid level sensor 8 and the electric telescopic rod 7 are electrically connected to a controller located on the fixed plate 4 via a cable (not shown in the figure, but could be a PLC, intelligent processor, etc.); the controller is electrically connected to an audible and visual alarm (not shown in the figure) installed on the fixed plate 4 via a cable.

[0027] Walls 9 are built on both sides of the structural column 1. Baffles 11 and two clamping blocks 12 are fixedly connected to the walls 9 on both sides of the pouring port 3 by tie rods 10 and nuts. The baffles 11 are located on the side of the pouring port 3 away from the diversion plate 6. The baffles 11 abut against and cover the pouring port 3. The two clamping blocks 12 are located on both sides of the template device (an abbreviation of a CNC template device for automated forming of post-pouring wall columns, which will be consistent in the following text). Limiting blocks 13 are welded to the surfaces of the two side plates 5 near the corresponding clamping blocks 12. The limiting blocks 13 are slidably connected to the clamping blocks 12.

[0028] As shown in the figure, a baffle 11 is fixedly installed on one side of the pouring port 3 with bolts and nuts, and a template device is fixedly installed on the other side with bolts and nuts. At this time, the diversion plate 6 is tilted and opened to its maximum state, located at the initial end of the movement trajectory. The working end of the electric telescopic rod 7 has not extended, and concrete begins to be poured towards the pouring port 3. After the concrete has been poured for a period of time, when the concrete begins to overflow between the two side plates 5 and the diversion plate 6, the ultrasonic liquid level sensor 8 constantly detects the liquid level of the concrete and transmits its liquid level data to the controller. When the volume of concrete between the two side plates 5 and the diversion plate 6 reaches a certain level, the ultrasonic liquid level sensor 8 detects the liquid level of the concrete and transmits its liquid level data to the controller. The volume of the three empty spaces at the pouring port When equal (in combination) Figure 3As shown in the diagram, the controller activates an audible and visual alarm to alert construction workers to stop pouring concrete. Then, the controller activates the electric telescopic rod 7, extending its working end and rotating the diversion plate 6 towards the pouring opening 3 until its surface covers and adheres tightly to the outer surface of the pouring opening 3. At this point, the concrete between the side plates 5 and the diversion plate 6 precisely fills the gap at the pouring opening 3. The pouring opening 3 and the structural column 1 are then completely filled with concrete, completing the pouring process. The operation is simple and convenient, eliminating the need for construction workers to constantly monitor the concrete level at the diversion plate 6. This allows for precise measurement of the concrete pouring volume, preventing gaps or excessive chipping during the pile foundation construction of the structural column 9, thus ensuring construction quality.

[0029] The volume at the three pouring inlets ( = + This can be determined through prior measurement and calculation. This indicates the current volume of concrete within the pouring inlet 3, which can be determined through the coordination of the controller and the ultrasonic level sensor 8. Because the trajectory of the diversion plate 6 is fixed, the angle α between the upper surface of the diversion plate 6 and the vertical plane is fixed at the initial end. Furthermore, the difference between the concrete level height measured by the ultrasonic level sensor 8 and the previous initial height can be used to calculate the volume of concrete on the upper surface of the diversion plate 6 using a formula pre-stored in the controller. = At that time, the audible and visual alarm started working, the construction workers stopped pouring concrete, and the diversion plate 6 covered the pouring port 3 under the action of the electric telescopic rod 7.

[0030] In this embodiment, a vibratory assembly 14 is installed on the surface of the diversion plate 6 away from the pouring port 3. The vibratory assembly 14 includes a movable block 1401 that is horizontally slidably disposed on the surface of the diversion plate 6 and a drive motor 1402 that drives the movable block 1401 to reciprocate in the horizontal direction. The drive motor 1402 is fixed to the surface of the diversion plate 6 by bolts. The movable block 1401 is mounted on the surface of the diversion plate 6, and a support member 1403 is provided between the movable block 1401 and the diversion plate 6. The support member 1403 is fixedly connected to the surface of the diversion plate 6 by bolts. Abutment blocks 1404 are respectively provided at both ends of the movable block 1401. The two abutment blocks 1404 are vertically fixed to the surface of the diversion plate 6, and when the drive motor 1402 drives the movable block 1401 to reciprocate, the two ends of the movable block 1401 intermittently abut against the corresponding abutment blocks 1404.

[0031] As shown in the figure, the drive motor 1402 drives the movable block 1401 to reciprocate horizontally. During the reciprocating motion, the two ends of the movable block 1401 intermittently abut against the two abutment blocks 1404, causing vibration. The drive motor 1402 is a high-speed, low-load motor, which can drive the movable block 1401 to quickly and intermittently contact the two abutment blocks 1404, causing the entire diversion plate 6 to vibrate at high frequency. When concrete passes over the surface of the diversion plate 6, the high-frequency vibration of the diversion plate 6 can effectively prevent concrete from adhering to its surface. Furthermore, when the concrete level rises to between the two side plates 5 and the diversion plate 6, the high-frequency vibration of the diversion plate 6 can also play a certain role in compacting the concrete, effectively reducing the gas in the concrete, improving the accuracy of the ultrasonic sensor when detecting the concrete surface, and ensuring... = This ensures the quality of the piles during the final pile construction.

[0032] Among them, combined Figure 6 As shown, a transmission component is connected between the output end of the drive motor 1402 and the movable block 1401 to convert the rotational motion of the output end of the drive motor 1402 into the reciprocating motion of the movable block 1401 in the horizontal direction. The prior art will not be described in detail.

[0033] In this embodiment, the two side plates 5 are slidably disposed on the upper surface of the fixed plate 4 in a horizontal direction; the surfaces of the diversion plate 6 that abut against the two side plates 5 are elastically slidably provided with movable plates 15; one end of each of the movable plates 15 abuts against the surface of the corresponding side plate 5, and the other end is fixedly connected to the diversion plate 6 with a spring (not shown in the figure); a horizontally disposed distance sensor 16 is installed on the surface of any side plate 5, and the detection end of the distance sensor 16 faces the surface of the other side plate 5; the distance sensor 16 is disposed on the side of the diversion plate 6 away from the pouring port 3; the distance sensor 16 is electrically connected to the controller.

[0034] As shown in the figure, the movable plates 15 that are elastically slidably inserted on both sides of the diversion plate 6 can improve the applicability of this template device to a certain extent, and can adapt to pouring openings 3 of different widths within a certain range, thus improving the applicability of the invention without affecting its normal use. The distance sensor 16 can monitor the distance between the two side plates 5 at all times and transmit the data to the controller for easy calculation. Furthermore, when the drive motor 1402 drives the movable block 1401 to make gap contact with the abutment blocks 1404 on both sides, the kinetic energy generated by the vibration of the abutment blocks 1404 and the movable plate 15 due to the spring connecting the two movable plates 15 and the diversion plate 6 will also cause a slight sway between the diversion plate 6 and the two movable plates 15. Under the high-frequency rotation of the drive motor 1402, the slight sway will be further amplified, ultimately improving the vibration effect of the diversion plate 6 and the accuracy of the ultrasonic sensor when detecting the concrete surface.

[0035] In this embodiment, buffer blocks 17 are elastically inserted through the two side surfaces of the movable block 1401 facing the two abutting blocks 1404, and a spring (not shown in the figure) is fixedly connected between the buffer block 17 and the movable block 1401.

[0036] Combination Figure 5 As shown, when the movable block 1401 drives one of the buffer blocks 17 to abut against the corresponding abutting block 1404, the end face of the buffer block 17 away from the movable block 1401 first abuts against the surface of the abutting block 1404. At this time, the spring inside the movable block 1401 is compressed, and the drive motor 1402 continues to drive the movable block 1401 to move towards the abutting block 1404 until the spring is compressed to its minimum. The movable block 1401 then abuts against the spring, and the impact force generated during the abutment is transmitted to the abutting block 1404 through the spring, causing the diverting plate 6 to vibrate. The drive motor 1402 drives the movable block 1401 to move towards the abutment block 1404 on the other side. After moving a certain distance, the compressed spring releases its elastic potential energy, which pushes the buffer block 17 to strike the movable block 1401 (the movable block 1401 will limit the buffer block 17 to prevent the buffer block 17 from sliding out of the movable block 1401). The impact force generated by the impact is transmitted to the diversion plate 6 through the support member 1403, which increases the frequency of vibration of the diversion plate 6. The movable plate 15 moves back and forth in this way, which can further improve the vibration effect of the diversion plate 6.

[0037] In this embodiment, multiple pressure sensors (not shown in the figure) are installed on the surface of the diversion plate 6 near the pouring port 3, and the multiple pressure sensors are spaced apart in the vertical direction; all the pressure sensors are electrically connected to the controller.

[0038] When the diversion plate 6 rotates towards the pouring opening 3 under the action of the electric telescopic rod 7, the concrete liquid level accumulated between the two side plates 5 and the diversion plate 6 will rise accordingly. The pressure sensor installed on the surface of the diversion plate 6 will constantly detect the pressure status on its surface. When the diversion plate 6 rotates to abut against the pouring opening 3, the concrete accumulated between the two side plates 5 and the diversion plate 6 should fill the entire pouring opening 3. Therefore, the lateral pressure of the concrete in the pouring opening 3 can be checked by multiple pressure sensors set vertically at intervals. When the pouring opening 3 is not completely filled with concrete, the data measured by the corresponding pressure sensors can quickly draw a conclusion, making it convenient for construction personnel to observe the filling status of the concrete in the pouring opening 3 after the diversion plate 6 is closed.

[0039] In this embodiment, an adjustable telescopic rod 18 is hinged to the lower surface of the fixed plate 4, and a base plate 19 is hinged to the end of the telescopic rod 18 away from the fixed plate 4; the base plate 19 is placed on the ground, and one side surface of the base plate 19 abuts against the surface of the structural column 1, which can effectively support the template device.

[0040] Among them, a U-shaped protective block 20 is connected between the two side plates 5; the protective block 20 is set above the pouring port 3, and the protective block 20 is retractable along the length of the crossbeam 2 (the prior art will not be described in detail).

[0041] In this embodiment, the rotating shaft of any of the movable plates 15 extends out of the side plate 5 and is connected to an angular displacement sensor (not shown in the figure); the angular displacement sensor is fixed to the surface of the side plate 5 by bolts; the angular displacement sensor is used to measure the angle α between the upper surface of the diversion plate 6 and the vertical plane, and the angular displacement sensor is electrically connected to the controller by a cable.

[0042] Combination Figure 3 As shown, when the diversion plate 6 moves towards the pouring port 3 under the drive of the electric telescopic rod 7, the concrete liquid level and the included angle α between the two side plates 5 and the diversion plate 6 will change constantly. Through the cooperation of the angular displacement sensor and the ultrasonic liquid level sensor 8, the concrete level can be calculated in real time during the movement of the diversion plate 6. and Whether they are equal, ensuring that after the diversion plate 6 abuts against the surface of the pouring opening 3, the gap inside the pouring opening 3 is exactly filled with concrete; and when the electric telescopic rod 7 drives the diversion plate 6 to reset, the included angle α can be detected by the angular displacement sensor, thereby ensuring the calculation Accuracy of time.

[0043] Working principle of this invention:

[0044] S1. The tie rod 10 is pre-embedded in the wall 9 on both sides of the structural column 1. First, the baffle 11 is fixed to one side of the pouring opening 3 by the cooperation of the nut and the tie rod 10, and the baffle 11 covers the pouring opening 3. The two clamping blocks 12 are fixed on both sides of the pouring opening 3. The two clamping blocks 12 and the baffle 11 are respectively located on both sides of the structural column 1. Then, one end of the template device is pressed tightly against the surface of the structural column 1 and slid upward toward the pouring opening 3 until the limiting block 13 and the clamping block 12 abut against each other. The upper surface of the fixing plate 4 is at the same level as the lower opening of the pouring opening 3, and the surfaces of the two side plates 5 are at the same level as the two sides of the pouring opening 3. Tighten the nuts on the surface of the clamping block 12 again and fix the template device here. Adjust the length of the telescopic rod 18 so that the bottom plate 19 contacts the ground. Calculate the volume at the pouring opening 3.

[0045] S2, the electric telescopic rod 7 is in the initial position. The controller controls the drive motor 1402 to work and begin pouring concrete into the pouring port 3. When the concrete level rises to the pouring port 3 and contacts the diversion plate 6, the flow rate of the concrete is reduced. The ultrasonic level sensor 8 constantly monitors the distance between the concrete level and the upper surface of the diversion plate 6. When the controller calculates... = When the alarm sounds, the construction workers stop pouring concrete.

[0046] S3. The controller controls the electric telescopic rod 7 to start working, so that the diversion plate 6 moves slowly towards the pouring port 3 until the diversion plate 6 comes into contact with the surface of the pouring port 3. The controller judges whether there is a gap in the pouring port 3 based on the data detected by multiple pressure sensors. If there is a gap, the diversion plate 6 is opened to pour some more concrete and the S2 process is repeated; if there is no gap, the concrete pouring is completed.

[0047] S4. Remove the formwork device and telescopic rod 18. Use a baffle 11 with a size larger than the pouring opening 3 to slide into the two clips 12 so that the baffle 11 abuts against and covers the exposed pouring opening 3. Wait for a period of curing work. The formwork device can be moved to the next construction site and the above operation can be repeated.

[0048] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of the present invention.
