Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of building construction, specifically to a plug-in positioning plate for a concrete vibrator and a concrete vibration device. Background Technology
[0002] During the pouring process, loose areas often form due to gaps between formwork or the settlement of the concrete itself. This not only affects the overall strength of the concrete structure, but may also lead to problems such as cracks and leakage. To solve these problems, concrete vibrators are widely used in construction projects. Through mechanical vibration, the concrete can be filled more evenly inside the formwork and the air bubbles and voids inside can be eliminated, thereby improving the quality and strength of the concrete.

[0036] The principles and features of this utility model are described below. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.
[0037] Example 1
[0038] like Figures 3-5 As shown, this embodiment of a plug-in positioning plate for a concrete vibrator includes a plate body and an elastic damping mechanism 2. The plate body has a plug-in hole 17 in the middle and a connecting groove 12 in the middle of the front side of the plate body. One end of the connecting groove 12 communicates with the plug-in hole 17. The elastic damping mechanism 2 is installed in the connecting groove 12. The elastic damping mechanism 2 includes a movable block 21 and a spring 22. The movable block 21 is adapted to slide in the connecting groove 12. One end of the movable block 21 is connected to the end of the connecting groove 12 away from the plug-in hole 17 by the spring 22. The other end of the movable block 21 is placed in the plug-in hole 17. The space between the other end of the movable block 21 and the inner wall of the plug-in hole 17 serves as the plug-in channel 14 for the shaft sleeve 51 of the concrete vibrator.
[0039] In this embodiment, only one connecting groove 12 can be provided in the center of the front of the plate, and an elastic damping mechanism 2 can be used to limit the speed at which the bushing 51 is pulled out of the insertion and removal channel 14.
[0040] To make the force on bushing 51 more even, such as Figure 3 and Figure 4 As shown, the front center of the plate has multiple connecting grooves 12, and each connecting groove 12 contains an elastic damping mechanism 2. By providing multiple connecting grooves and multiple elastic damping mechanisms, it is convenient to fit the bushing from multiple directions.
[0041] Preferred, such as Figure 3 and Figure 4 As shown, two connecting grooves 12 located in a straight line are opened in the center of the front of the plate, which can be fitted from the opposite sides of the bushing 51.
[0042] Another preferred embodiment of this solution is as follows: Figure 3 and Figure 4As shown, in this embodiment, the insertion / removal hole 17 is a circular hole, and the connecting groove 12 and the movable block 21 are both arranged to extend radially along the insertion / removal hole 17. Arranging the connecting groove and the movable block to extend radially along the insertion / removal hole ensures that the bushing is subjected to uniform and stable force.
[0043] The movable block 21 can be a long strip block; optionally, the two opposite sidewalls of the movable block 21 can be convex arc-shaped structures, and the two opposite sidewalls of the connecting groove 12 can be concave arc-shaped structures. The movable block 21 can be limited within the connecting groove 12 and can slide along the connecting groove 12.
[0044] The concrete vibrator in this embodiment can be any commonly used equipment for concrete compaction in building construction. The concrete vibrator includes a power unit 5, a bushing 51, a vibrating rod 52, and a flexible shaft. The power unit 5 can be an electric motor. The output shaft of the power unit is connected to the flexible shaft and drives its rotation. One end of the bushing 51 is fixed to the main structure of the power unit 5. The bushing 51 is fitted onto the flexible shaft, and the free end of the flexible shaft is connected to the vibrating rod 52. The other end of the bushing 51 is spaced apart from the vibrating rod 52. A support is provided at the bottom of the power unit 5. Driven by the electric motor, the flexible shaft vibrates within the bushing 51, driving the vibrating rod 52 to compact the concrete. The bushing 51 is not driven by the electric motor.
[0045] When the shaft sleeve 51 of the concrete vibrator is placed in the insertion and removal channel 14, and the spring 22 is in a free state, it pushes the movable block 21 to fit against the shaft sleeve 51. The fitting force between the movable block 21 and the shaft sleeve 51 does not affect the normal use of the flexible shaft, nor does it affect the normal force to slowly pull out the shaft sleeve.
[0046] This embodiment uses a plug-in and pull-out positioning plate for a concrete vibrator. It is set above the concrete that needs to be vibrated. The vibrator rod, bushing, and flexible shaft inside the bushing can all pass through the plug-in and pull-out channel to contact the concrete. A spring pushes the movable block to make the movable block fit against the bushing, increasing the force required to pull out the bushing, thereby limiting the pull-out speed and preventing rapid pull-out from leaving holes on the concrete surface.
[0047] Example 2
[0048] Based on Embodiment 1, this embodiment also provides a preferred embodiment of the active block 21. For example... Figure 3 and Figure 4 As shown, a toggle member 23 is fixed to the upper surface of the movable block 21 at the end opposite to the insertion hole 17, and the toggle member 23 protrudes from the front of the plate. By providing the toggle member, it is easy to move the movable part.
[0049] Optionally, the actuating element 23 can be a plate-like structure or a block-like structure. For example... Figure 3 and Figure 4As shown, the actuating element 23 adopts a plate-like structure.
[0050] Example 3
[0051] Based on Embodiment 1 or Embodiment 2, this embodiment provides another preferred solution for the active block 21. For example... Figure 3 and Figure 4 As shown, a rubber block 24 is connected to one end of the movable block 21, which is placed inside the insertion hole 17. The rubber block increases the friction with the bushing and also prevents the bushing from being scratched during the removal process.
[0052] Further preferred, such as Figure 3 and Figure 4 As shown, the side of the rubber block 24 facing away from the movable block 21 is a convex arc surface, and the central axis of the arc surface is parallel to the central axis of the insertion hole 17. The arc surface on the rubber block facilitates its fit with the bushing.
[0053] Example 4
[0054] Based on any of Embodiments 1 to 3, this embodiment provides a preferred fit between the movable block and the connecting groove 12. For example... Figure 4 As shown, each of the two opposite inner sidewalls of the connecting groove 12 is provided with a sliding groove 13. The sliding groove 13 extends along the length of the connecting groove 12 and is closed at both ends. The opposite sidewalls of the movable block 21 are respectively provided with sliders 25 that are adapted to slide and engage with the sliding grooves 13. By setting the sliding grooves and sliders, the movable block can slide stably within the connecting groove.
[0055] Example 5
[0056] Based on any of Embodiments 1 to 4, this embodiment provides a preferred solution for the plate. For example... Figures 3-5 As shown, the plate includes a foot pedal 1 and a transparent plate 11. The foot pedal 1 has a mounting hole in its center, and the transparent plate 11 is embedded in the mounting hole. The insertion / removal hole 17, the connecting groove 12, and the elastic damping mechanism 2 are all disposed on the transparent plate 11. An anti-slip protrusion 15 is fixed to the front of the foot pedal 1, and an anti-slip pad 16 is fixed to the back of the foot pedal 1. The transparent plate facilitates observation of the depth of the vibrator inserted into the concrete, the vibration of the concrete, and the removal of the bushing. The anti-slip pad 16 prevents slippage between the positioning plate and the formwork.
[0057] In a preferred embodiment, the mounting hole is a circular hole, and the transparent plate 11 is a circular plate. The anti-slip pad 16 does not obstruct the area where the transparent plate is located.
[0058] Specifically, multiple anti-slip protrusions 15 are provided on both sides of the foot pedal 1 of the transparent plate 11. The anti-slip protrusions 15 can be made of the same material as the foot pedal 1, or they can be made of rubber material fixed to the foot pedal 1. The anti-slip protrusions prevent slippage when stepping on the positioning plate.
[0059] Another preferred embodiment is that a magnetic block 18 is fixed on the back of the plate. Magnetic blocks 18 can be set on the foot pedals 1 on both sides of the transparent plate 11. The magnetic blocks 18 can attract the metal steel bars and prevent the positioning plate from sliding randomly after being placed on the building formwork.
[0060] Example 6
[0061] In order to record the vibration time, such as Figure 3 and Figure 4 As shown, a timer 3 and a switch 4 are also fixed to the front of the plate, and the switch 4 is electrically connected to the electrical control terminal of the timer 3. By setting the timer and switch, it is easy to confirm whether the vibration time of the concrete exceeds the standard.
[0062] In this embodiment, both timer 3 and switch 4 can be commercially available timers. The switching principle and timing principle of the timer are existing technologies and will not be described in detail here.
[0063] Example 7
[0064] like Figures 1-5 As shown, a concrete vibration device of this embodiment includes a plug-in positioning plate for a concrete vibrator as described in any one of embodiments 1 to 6, and also includes a concrete vibrator; when the spring 22 is in a compressed state, the bushing 51 and the vibrating rod 52 of the concrete vibrator can freely pass through the plug-in channel 14; when the spring 22 is in a free state, the bushing 51 is in contact with the other end of the movable block 21 and the inner wall of the plug-in hole 17.
[0065] Figure 1 and Figure 2 The bending method of the central bushing 51 is random and is not limited to the bending method shown in the figure.
[0066] When using the concrete vibration device in this embodiment, a positioning plate of appropriate size is selected according to the concrete pouring requirements. The positioning plate is placed above the vibration point, and the anti-slip pad at the bottom of the positioning plate is made to fit against the metal steel frame or building formwork. The movable block is moved to both sides to pass the vibrator through the transparent plate. The positioning plate is stepped on to prevent slippage. The power unit is started to drive the vibrator to vibrate in conjunction with the flexible shaft. Then the vibrator is lowered to quickly insert it into the concrete. The foot switch is pressed to start the timer to start the vibration timing. At the same time, the movable block is released, and the spring pushes the movable block to move so that the rubber block on one side of the movable block contacts the bushing outside the flexible shaft. After the vibration time reaches the standard, the flexible shaft is pulled out. The contact between the rubber block and the bushing increases the friction and limits the speed at which the flexible shaft is pulled out, thereby ensuring that the vibrator is quickly inserted and slowly pulled out, preventing the vibrator from being pulled out too quickly and leaving holes in the concrete.
[0067] The concrete vibration device in this embodiment can use an elastic damping mechanism to limit the pull-out speed of the bushing, preventing rapid pull-out from leaving holes on the concrete surface, and achieving good concrete vibration effect.
