Description

Technical Field

[0001] This invention relates to the field of bridge engineering technology, and in particular to a concrete vibration device and a concrete vibration method. Background Technology

[0002] For a precast column with a standard grid-shaped stirrup cross section, the transverse stirrups and longitudinal stirrups intersect perpendicularly in the plane, forming multiple rectangular cross sections.

[0003] The current method for vibrating concrete in the construction of tall columns involves the following steps: An operating platform is set up at the top of the column formwork, on which multiple external motors in cages are placed. Concrete vibrators and their flexible hoses are connected to these motors. After concrete pouring, workers must vibrate each rectangular section sequentially. During vibration, due to the obstruction of the stirrups, the vibrators and their hoses must be repeatedly lifted to the top of the column and then lowered to another rectangular section, making the operation cumbersome. Furthermore, because the existing vibrator hoses are quite long, with the flexible shaft located inside the hose, the hose cannot be bent during construction. Driven by the external motor, the hose vibrates violently, and after construction, the hose cannot be retracted and is simply left haphazardly on the operating platform, posing a significant safety hazard. In addition, the current method requires multiple workers to cooperate, resulting in high construction costs. Moreover, the selection of vibration points by workers is often arbitrary, making it difficult to control the position of the vibrator during vibration. This easily leads to over-vibration or under-vibration of certain concrete sections, resulting in honeycomb pores and cracks on the column surface later, affecting the overall strength of the concrete structure. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the problems of inaccurate selection of vibration points and difficulty in fixing the position of the vibrator during vibration in the prior art, which leads to under-vibration and over-vibration, as well as the inconvenience of construction operation, and to provide a concrete vibration device and concrete vibration method.

[0005] The present invention solves the above-mentioned technical problems through the following technical solution:

[0006] This invention provides a concrete vibration device for vibrating precast columns with standard grid-shaped stirrup cross-sections. The transverse and longitudinal stirrups of the precast columns intersect perpendicularly on a horizontal plane to form multiple vibration zones. The concrete vibration device includes an operating platform, a support frame, a horizontal moving component, a vertical moving component, and a vibrator.

[0007] The support frame is fixed to the upper surface of the operating platform and extends vertically upward; the horizontal moving component includes a fixing part and a sliding groove. The fixing part is fixed to the upper end of the support frame, and the sliding groove is located at the end of the fixing part facing the operating platform. The sliding groove extends horizontally along a preset path and cooperates with the vibrating rod, and the vibrating rod can move horizontally along the extension direction of the sliding groove; the vertical moving component is connected to the vibrating rod and is used to drive the vibrating rod to move vertically.

[0008] In this solution, the aforementioned structural form is adopted, with a fixed movement path for the vibrator. Vibration is performed on corner points of the vibration area along this fixed path, avoiding the problem of arbitrary selection of vibration points by manual operation. When vibrating a specific point, the vibrator can be fixed at that point, resulting in more precise vibration and solving the problems of missed or over-vibration in some areas caused by manual operation. The horizontal and vertical movement components allow the vibrator to move horizontally and vertically without the need for manual lifting, making operation more convenient during vibration and improving construction efficiency.

[0009] Preferably, the vertical movement component includes a connecting rope and a drive pulley, the lower end of the connecting rope being connected to the vibrating rod, and the upper end of the connecting rope being connected to the drive pulley, the drive pulley being used to adjust the extension length of the connecting rope.

[0010] In this solution, the above-mentioned structural form is adopted, and the extension length of the connecting rope is adjusted by adjusting the drive pulley, thereby controlling the position of the vibrator in the vertical direction.

[0011] Preferably, the vertical movement component further includes a suspension connector, the upper end of which is provided with multiple connection holes, the end of the connecting rope near the vibrator includes multiple connecting rope units, the number of connection holes and the number of connecting rope units are the same and they are connected one-to-one, and the lower end of the suspension connector is connected to the vibrator.

[0012] In this solution, the above-mentioned structural form is adopted. The suspension connector is used to connect the vertical moving component and the vibrator, so that the vertical moving component can drive the vibrator to move in the vertical direction; the suspension connector and the connecting rope are connected at multiple points, making the connection more secure.

[0013] Preferably, the suspension connector is provided with a cable hole, and the cable hole is through at both ends in the vertical direction;

[0014] The vibrating rod includes a driver, a cable, a hollow hose, and a vibrating rod head. The driver is placed on the operating platform. The lower end of the hollow hose is connected to the vibrating rod head. One end of the cable is connected to the driver, and the other end of the cable passes through the cable hole and the hollow hose and is connected to the vibrating rod head.

[0015] In this solution, the above-mentioned structural form is adopted, which can keep the hollow hose vertical and control the vibrator to be lowered vertically into the concrete. This solves the problems in the existing technology where it is difficult to ensure the verticality of the hollow hose when it is manually placed, which leads to bending of the hollow hose during the lowering process, strong shaking of the hollow hose during vibration, inaccurate vibration point positioning, and inconvenience in storing the vibrator after construction.

[0016] Preferably, the vertical moving component is located at the lower end of the horizontal moving component and connected to the slide groove, and the vibrating rod is connected to the horizontal moving component through the vertical moving component.

[0017] In this solution, the above-mentioned structural form is adopted, in which the vertical moving component is connected to the horizontal moving component, and the vertical moving component and the vibrator can move synchronously in the horizontal direction, so that the vibrator always remains vertical during the horizontal movement.

[0018] Preferably, the horizontal moving assembly includes a T-shaped rod and a horizontal pulley, the crossbar of the T-shaped rod extending into the groove, and the two ends of the horizontal pulley in the vertical direction abutting against the lower end face of the crossbar and the inner wall of the groove, respectively.

[0019] In this solution, the above-mentioned structural form is adopted. The horizontal pulley cooperates with the T-shaped hanger, so that the T-shaped hanger slides along the slide groove, thereby driving the vibrator to move in the horizontal direction. The crossbar part of the T-shaped hanger extends into the interior of the slide groove. Through cooperation with the slide groove, the T-shaped hanger is prevented from falling off and the stability of the connection is ensured. The horizontal pulley below the crossbar makes the T-shaped hanger slide more smoothly in the slide groove.

[0020] Preferably, the groove is elliptical.

[0021] In this design, the above-mentioned structural form is adopted to fix the movement path of the vibrator, thereby better determining the corner point of vibration; the elliptical shape of the slide groove makes the sliding smoother.

[0022] Preferably, the central axis of the chute on the horizontal plane coincides with the central axis of the vibration area.

[0023] In this solution, the above-mentioned structural form is adopted so that the center of the chute is located in the center of the vibration area, which facilitates the positioning between the chute and the vibration area and is more conducive to vibration.

[0024] Preferably, the support frame includes a crossbeam and two vertical beams. The vertical beams are fixed to the upper surface of the operating platform. The two ends of the crossbeam are respectively connected to the upper ends of the two vertical beams. The axis of the crossbeam coincides with the central axis of the vibration area. The central axis of the chute on the horizontal plane coincides with the axis of the crossbeam.

[0025] In this scheme, the above-mentioned structural form is adopted, in which the axis of the crossbeam coincides with the central axis of the vibration area, and the chute is fixed to the crossbeam so that the central axis of the chute on the horizontal plane coincides with the axis of the crossbeam, thereby fixing the chute at the center of the vibration area.

[0026] The present invention also provides a method for vibrating concrete, which uses the aforementioned concrete vibration device, and the method includes the following steps:

[0027] Step S1: Determine the planar position of the chute and install the concrete vibrating device;

[0028] Step S2: Test whether the position of the vibrating head of the vibrating rod meets the requirements; if yes, proceed to step S3; if no, return to step S1 and redetermine the planar position of the slide groove.

[0029] Step S3: Drive the vibrator to move to one of the corner points of the vibration area using the horizontal moving component;

[0030] Step S4: Lower the vibratory rod using the vertical moving component and drive the vibratory rod to vibrate the corner point;

[0031] Step S5: When the vibration time at the corner point meets the preset vibration time, lift the vibrator and drive the vibrator to move to the next corner point of the vibration area through the horizontal moving component, and repeat step S4.

[0032] Step S6: Repeat step S5 until all corners of the vibration area have been vibrated.

[0033] In this solution, the above-mentioned operation method is adopted, and the vibration time at each corner point is the same, which makes the vibration more uniform and avoids the problems of under-vibration and over-vibration in some areas during manual operation.

[0034] Preferably, in step S2, it is determined whether the minimum horizontal distance between the vertical projection point of the vibrating rod head in the corresponding vibration area and the tangent circle in the corresponding vibration area is greater than half the diameter of the vibrating rod head; if yes, the position of the vibrating rod head meets the requirements; if no, the position of the vibrating rod head does not meet the requirements.

[0035] In this solution, the above operating method can ensure that the chute is positioned properly and avoid the vibrator head colliding with the surrounding stirrups during construction.

[0036] Preferably, in step S6, the straight-line distance of a single horizontal movement of the vibrator shall not exceed 1.5 times the vibration radius of the vibrator.

[0037] In this solution, the above-mentioned operating method is adopted so that the vibrator can fully vibrate the vibrating area.

[0038] Preferably, multiple vibration zones are vibrated simultaneously, and each vibration zone is equipped with a concrete vibration device.

[0039] In this solution, the above-mentioned operating method is adopted, thus eliminating the need to repeatedly lift the vibrator to another vibrating area during the construction process, making the operation more convenient, saving construction time, and improving construction efficiency.

[0040] Preferably, when multiple vibration zones are vibrated simultaneously, the concrete vibration method includes the following steps:

[0041] Step S01: Select any one of the vibration areas as the starting area, and perform steps S3 and S4 on the vibrator in the starting vibration area;

[0042] Step S02: Select the vibrating rod of the adjacent vibration area in a clockwise or counterclockwise direction, and execute steps S3 and S4;

[0043] Step S03: Repeat step S02 until all corners of the vibration area have started to vibrate;

[0044] Step S04: Return to the starting area and proceed to step S5;

[0045] Step S05: Repeat step S02 until all new corners of the vibration area have started to vibrate;

[0046] Step S06: Repeat steps S04 and S05 until all corners of the entire vibration area have been vibrated.

[0047] In this solution, the above-mentioned operating method is adopted, so that all corners of the vibration area are vibrated, and the operation is more convenient, less manpower is required, and the construction efficiency is higher.

[0048] The positive and progressive effects of this invention are as follows:

[0049] This invention provides a concrete vibration device that allows for more accurate selection of vibration points and a more fixed position of the vibrator during vibration, avoiding over-vibration and under-vibration problems caused by manual operation. This results in more uniform vibration, more convenient construction operations, less manpower required, and higher construction efficiency. This invention also provides a concrete vibration method that uses this concrete vibration device to achieve the same effects. Attached Figure Description

[0081] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments.

[0082] like Figure 1 and Figure 2 The present invention is shown as a preferred embodiment of the present invention. The concrete vibrating device is used to vibrate precast columns with standard grid-shaped stirrup cross sections. The transverse stirrups and longitudinal stirrups of the precast columns intersect perpendicularly on the horizontal plane to form multiple rectangular cross sections. The vibration area 6 is square or rectangular.

[0083] The concrete vibrating device includes an operating platform 1, a support frame 2, a horizontal moving component 3, a vertical moving component 4, and a vibrator 5. The operating platform 1 is used to fix the support frame 2, and the horizontal moving component 3 is fixed to the support frame 2.

[0084] The support frame 2 is fixed on the upper surface of the operating platform 1 and extends upward in the vertical direction; the horizontal moving component 3 includes a fixing part 31 and a slide 32. The fixing part 31 is fixed on the upper end of the support frame 2, and the slide 32 is located at the end of the fixing part 31 facing the operating platform 1. The slide 32 extends along a preset path in the horizontal direction and cooperates with the vibrating rod 5. The vibrating rod 5 can move horizontally along the extension direction of the slide 32; the vertical moving component 4 is connected to the vibrating rod 5 and is used to drive the vibrating rod 5 to move in the vertical direction.

[0085] The shape of the fixing part 31 of the horizontal moving component 3 matches the shape of the rectangular cross-section of the vibration area 6. When the vibration area 6 is square, the fixing part 31 is circular; when the vibration area 6 is rectangular, the fixing part 31 is elliptical. In this embodiment, the fixing part 31 is circular. In other alternative embodiments, the fixing part 31 may also be an ellipse or other shapes that are considered suitable by those skilled in the art.

[0086] With the above-described structure, the movement path of the vibrator 5 is fixed. Vibration is performed at the corner point 61 of the vibration area 6 along this fixed path, avoiding the problem of arbitrary selection of vibration points by manual operation. When vibrating a specific point, the vibrator 5 can be fixed at that point, resulting in more precise vibration and solving the problems of missed or over-vibration in some areas caused by manual operation. The horizontal movement component 3 and the vertical movement component 4 allow the vibrator 5 to move horizontally and vertically without the need for manual lifting, making operation more convenient and improving construction efficiency.

[0087] like Figure 3 As shown, the vertical moving component 4 includes a connecting rope 41 and a drive pulley 42. The lower end of the connecting rope 41 is connected to the vibrating rod 5, and the upper end of the connecting rope 41 is connected to the drive pulley 42. The drive pulley 42 is used to adjust the extension length of the connecting rope 41.

[0088] The vertical movement component 4 adjusts the length of the connecting rope 41 via the drive pulley 42, thereby adjusting the vertical position of the vibrator 5. The drive pulley 42 can be a hand-cranked pulley, an electric pulley, or other pulleys with driving functions. The connecting rope 41 can be a steel wire rope or other materials deemed suitable by those skilled in the art.

[0089] like Figure 5 As shown, the vertical moving component 4 also includes a suspension connector 43. The upper end of the suspension connector 43 is provided with multiple connecting holes 431. The end of the connecting rope 41 near the vibrating rod 5 includes multiple connecting rope units 411. The number of connecting holes 431 and connecting rope units 411 are the same and they are connected one-to-one. The lower end of the suspension connector 43 is connected to the vibrating rod 5.

[0090] The suspension connector 43 is used to connect the vertical moving assembly 4 and the vibrating rod 5. The number of connecting holes 431 and connecting rope units 411 can be two, or any other number deemed suitable by those skilled in the art. The connecting holes 431 are located at both ends of the suspension connector 43 and are symmetrically arranged, thereby making the connection between the vertical moving assembly 4 and the vibrating rod 5 more stable.

[0091] The suspension connector 43 is provided with a cable hole 432, which is through at both ends in the vertical direction;

[0092] like Figure 6 As shown, the vibrating rod 5 includes a driver 51, a cable 52, a hollow hose 53, and a vibrating rod head 54. The driver 51 is placed on the operating platform 1. The lower end of the hollow hose 53 is connected to the vibrating rod head 54. One end of the cable 52 is connected to the driver 51, and the other end of the cable 52 passes through the cable hole 432 and the hollow hose 53 and is connected to the vibrating rod head 54.

[0093] The cable hole 432 on the suspension connector 43 allows the cable 52 to pass through. The cable hole 432 is located in the middle of the suspension connector 43, but it can also be located in other places that are deemed suitable by those skilled in the art. The hollow hose 53 contains only the cable 52, so that only the vibrator head 54 vibrates during use, and the hollow hose 53 does not vibrate, thus making the vibration point more accurate.

[0094] The vertical moving component 4 is located at the lower end of the horizontal moving component 3 and is connected to the slide 32. The vibrating rod 5 is connected to the horizontal moving component 3 through the vertical moving component 4.

[0095] The vertical moving component 4 is connected to the horizontal moving component 3, so that the horizontal moving component 3 can drive the vibrating rod 5 to move in the horizontal direction.

[0096] like Figure 4 As shown, the horizontal moving assembly 3 includes a T-shaped rod 33 and a horizontal pulley 34. The crossbar of the T-shaped rod 33 extends into the slide groove 32, and the two ends of the horizontal pulley 34 in the vertical direction abut against the lower end face of the crossbar and the inner wall of the slide groove 32, respectively.

[0097] The horizontal pulley 34 works in conjunction with the T-shaped rod 33, allowing the T-shaped rod 33 to slide along the groove 32, thereby driving the vibrator 5 to move horizontally. The vertical moving component 4 is connected to the horizontal moving component 3 via the T-shaped rod 33 and the horizontal pulley 34, or other connection methods deemed suitable by those skilled in the art may be used.

[0098] The shape of the chute 32 matches the shape of the rectangular cross section of the vibration area 6. When the vibration area 6 is square, the chute 32 is circular; when the vibration area 6 is rectangular, the chute 32 is elliptical.

[0099] In this embodiment, the fixing part 31 of the horizontal moving component 3 is circular, with a diameter slightly larger than the side length of the rectangular cross-section of the vibration area 6. A groove 32 is formed inside the fixing part 31 to ensure the vibration range meets requirements and to prevent the vibrator head 54 from colliding with the surrounding stirrups during construction. In other alternative embodiments, the fixing part 31 can also be elliptical, with its major axis larger than the long side of the rectangular cross-section of the vibration area 6 and its minor axis larger than the short side of the rectangular cross-section of the vibration area 6. The groove 32 is also formed inside the fixing part 31 to ensure the vibration range meets requirements and to prevent the vibrator head 54 from colliding with the surrounding stirrups during construction.

[0100] The central axis of the chute 32 on the horizontal plane coincides with the central axis of the vibration zone 6.

[0101] When the chute 32 is elliptical, the major axis of the chute 32 coincides with the central axis in the direction of the longer side length of the vibration area 6, and the minor axis of the chute 32 coincides with the central axis in the direction of the shorter side length of the vibration area 6.

[0102] The support frame 2 includes a crossbeam 21 and two vertical beams 22. The vertical beams 22 are fixed on the upper surface of the operating platform 1. The two ends of the crossbeam 21 are respectively connected to the upper ends of the two vertical beams 22. The axis of the crossbeam 21 coincides with the central axis of the vibration area 6. The central axis of the chute 32 on the horizontal plane coincides with the axis of the crossbeam 21.

[0103] In actual installation, after installing the support frame 2, it is only necessary to ensure that the central axis of the sliding groove 32 of the horizontal connector coincides with the axis of the crossbeam 21. This ensures that the central axis of the sliding groove 32 on the horizontal plane coincides with the central axis of the vibration zone 6 in one direction, making the operation more intuitive. Typically, the axis of the crossbeam 21 is aligned with the central axis of the longer side of the vibration zone 6, but it is also possible to align the axis of the crossbeam 21 with the central axis of the shorter side of the vibration zone 6.

[0104] like Figure 7 The diagram illustrates a concrete vibration method using this concrete vibrator, which includes the following steps:

[0105] Step S1: Determine the plane position of the chute 32 and install the concrete vibrator;

[0106] Step S2: Test whether the position of the vibrating head 54 of the vibrating rod 5 meets the requirements; if yes, proceed to step S3; if no, return to step S1 and redetermine the planar position of the slide groove 32.

[0107] Step S3: Drive the vibrator 5 to move to one of the corner points 61 of the vibration area 6 by using the horizontal moving component 3;

[0108] Step S4: Lower the vibrator 5 using the vertical moving component 4 and drive the vibrator 5 to vibrate the corner point 61.

[0109] Step S5: When the vibration time at the corner point 61 meets the preset vibration time, lift the vibrator 5 and drive the vibrator 5 to move to the next corner point 61 of the vibration area 6 through the horizontal moving component 3, and repeat step S4.

[0110] Step S6: Repeat step S5 until all corners 61 of the vibration area 6 have been vibrated.

[0111] Step S7: After all corners 61 of the vibration area 6 have been vibrated, turn off all vibrators 5 in sequence, raise the vibrators 5 to a height of about 1 meter, pour about 50 cm of concrete, and repeat steps S3, S4, S5, and S6.

[0112] Step S8: Repeat step S7 until all concrete columns are poured and vibrated.

[0113] The preset vibration time can be 30 seconds, or other times that are deemed appropriate by those skilled in the art can be selected.

[0114] The number and location of the vibration corner points 61 are determined based on the effective vibration radius of the vibrator head 54 and the size of the vibration area 6. It is necessary to ensure that the selection of corner points 61 guarantees that the effective vibration radius of the vibrator head 54 at the selected corner point 61 covers the entire vibration area 6. Figure 7 The example shown is an embodiment of selecting 2 corner points 61 or 4 corner points.

[0115] The planar position of the chute 32 should ensure that the position of the lowered vibrator head 54 is appropriate, that is, to ensure that the vibrator head 54 does not collide with the surrounding stirrups during construction. The dimensions of the chute 32 are determined based on the dimensions of the vibration area 6 before it is opened, while also meeting the requirement of not colliding with the surrounding stirrups.

[0116] In step S2, it is determined whether the minimum horizontal distance between the vertical projection point of the vibrating head 54 of the vibrating rod 5 in the corresponding vibration area 6 and the tangent circle in the corresponding vibration area 6 is greater than half the diameter of the vibrating head 54 of the vibrating rod 5; if yes, the position of the vibrating head 54 of the vibrating rod 5 meets the requirements; if no, the position of the vibrating head 54 of the vibrating rod 5 does not meet the requirements.

[0117] The test can be conducted by lowering the connecting rope 41 of the vertical moving component. Specifically, it can be determined whether the minimum horizontal distance between the vertical projection point of the connecting rope 41 and the inscribed circle of the corresponding vibration area 6 is greater than half the diameter of the vibrating head 54 of the vibrating rod 5. If yes, the position of the vibrating head 54 of the vibrating rod 5 meets the requirements; otherwise, the position of the vibrating head 54 of the vibrating rod 5 does not meet the requirements.

[0118] In step S6, the straight-line distance of a single horizontal movement of the vibrator 5 shall not exceed 1.5 times the vibration radius of the vibrator 5.

[0119] The straight-line distance of a single horizontal movement refers to the horizontal distance that the vibrator 5 moves from one corner point 61 to the next corner point 61 during the vibration process. If the straight-line distance of a single horizontal movement is too large, it will lead to insufficient vibration of the concrete. Therefore, the straight-line distance of a single horizontal movement of the vibrator 5 is limited to not exceeding 1.5 times the vibration radius of the vibrator 5.

[0120] Multiple vibration zones 6 can be vibrated simultaneously, with each vibration zone 6 equipped with a concrete vibrating device.

[0121] When multiple vibration zones 6 are vibrated simultaneously, the concrete vibration method includes the following steps:

[0122] Step S01: Select any one of the vibration areas 6 as the starting area, and perform steps S3 and S4 on the vibrator 5 of the starting vibration area 6.

[0123] Step S02: Select the vibrator 5 of the adjacent vibration area 6 in a clockwise or counterclockwise direction, and execute steps S3 and S4.

[0124] Step S03: Repeat step S02 until all corners 61 of the vibration area 6 have started to vibrate.

[0125] Step S04: Return to the starting area and proceed to step S5;

[0126] Step S05: Repeat step S02 until all new corner points 61 of the vibration area 6 have started to vibrate.

[0127] Step S06: Repeat steps S04 and S05 until all corners 61 of the entire vibration area 6 have been vibrated.

[0128] Step S07: After all corners 61 of the vibration area 6 have been vibrated, turn off all vibrators 5 in sequence, raise the vibrators 5 to a height of about 1 meter, pour about 50 cm of concrete, and repeat steps S01, S02, S03, S04, S05, and S06.

[0129] Step S08: Repeat step S07 until all concrete columns are poured and vibrated.

[0130] In existing precast columns of this type, the rectangular cross-section formed by longitudinal and transverse stirrups generally has the following distribution characteristics: the rectangular cross-section at the outer edge is smaller, while the rectangular cross-section adjacent to the smaller outer edge is the largest. This embodiment primarily focuses on vibrating the rectangular cross-section area 6. In other alternative embodiments, vibration can also be performed on the smaller rectangular cross-section area 6.
