Description

Technical Field

[0001] The present invention relates to the technical field of concrete quality inspection, and particularly to a vibration formwork device for concrete density and its usage method. Background Art

[0002] Concrete pouring and vibrating construction, as a key process to ensure the compactness and durability of structures, is widely used in concrete construction projects such as bridges and buildings. However, due to non-standard vibrating operations or improper parameter control, quality problems such as numerous air holes, honeycombing and pockmarking, insufficient density in the vibrating omission area, over-vibrating segregation, and poor surface flatness are often caused. These problems not only reduce the structural strength but also may cause potential leakage or cracks.

[0003] The existing concrete vibrating construction mainly relies on manual operation, and there is no unified standard for vibrating spacing and frequency. This not only has low efficiency but is also easily affected by human factors, prone to vibrating omission, misjudgment of over-vibrating, and deviation in the positioning of internal holes, thus resulting in uneven density or undetected segregation risks in a timely manner. It is difficult to guarantee the stability of construction quality and further restricts the progress of the project.

Specific Embodiment

[0032] In order to more elaborately describe the technical solutions of the above - mentioned invention, specific embodiments are listed below to prove the technical effects; it should be emphasized that these embodiments are used to illustrate the present invention and not to limit the scope of the present invention.

[0033] The concrete density vibration formwork device provided by the present invention, as Figure 1 and Figure 2 shown, includes a concrete formwork 100 and a concrete pouring height positioning system 200, a walking positioning system 300, a vibration system 400, and a main control module 500 installed on the concrete formwork 100, wherein:

[0034] The concrete pouring height positioning system 200 includes cushion blocks 210, threaded steel bars 220, temperature sensors 230, smooth round steel bars 240, buoyancy plates 250, reflection discs 260, circular fasteners 270, and a first laser rangefinder 280. The cushion blocks 210 are installed at the bottom of the concrete formwork 100, and can be specifically one block or two independent blocks. The threaded steel bars 220 and the smooth round steel bars 240 are respectively vertically installed on the cushion blocks 210 to prevent the threaded steel bars 220 and the smooth round steel bars 240 from directly contacting the bottom plate, which may cause leakage after the concrete 101 is poured. A number of the temperature sensors 230 are fixedly installed at equal intervals on the threaded steel bars 220, so as to quickly and preliminarily locate the approximate height range of the concrete 101 pouring according to the temperature change of the temperature sensors 230. The density of the buoyancy plates 250 is less than that of the concrete 101. The circular fasteners 270 are fixed on the buoyancy plates 250 and sleeved on the smooth round steel bars 240. The reflection discs 260 are fixedly installed at the tops of the smooth round steel bars 240. The first laser rangefinder is fixedly installed on the surface of the buoyancy plate, and the laser direction faces the reflection disc. Specifically, the buoyancy plates 250 float with the concrete surface as the concrete 101 is poured. The first laser rangefinder 280 monitors the distance between the buoyancy plates 250 and the reflection discs 260 in real time, and further calculates the concrete pouring height.

[0035] The walking positioning system 300 includes a horizontal track 310, a horizontal sliding bolt 320, a vertical track 330, a vertical walking device 340, a lateral support device 350, an auxiliary support device 360, and a second laser rangefinder 370. The horizontal tracks 310 are symmetrically arranged at the top and bottom of the concrete formwork 100. The horizontal sliding bolts 320 are slidably installed on the horizontal tracks 310. The vertical track 330 is fixed between the upper and lower horizontal sliding bolts 320. Two vertically distributed vertical walking devices 340 are slidably installed on the vertical track 330. Each vertical walking device 340 is equipped with the second laser rangefinder 370, and the laser direction is directly opposite to the bottom position, which is used to monitor the distance between the two vertical walking devices 340 and the distance between the lower vertical walking device 340 and the bottom surface of the vertical track 330 in real time to determine the positions of the two vertical walking devices 340. The lateral support devices 350 and the auxiliary support devices 360 are installed on each vertical walking device 340 to temporarily fix the positions of the vertical walking devices 340 on the vertical track 330.

[0036] The vibration system 400 includes a vibrator 410, an auxiliary plate 420, a third laser rangefinder 430, and a fourth laser rangefinder 440. One end of the vibrator 410 is mounted on the side of the vertical traveling device 340, and the other end is mounted with the auxiliary plate 420. The auxiliary plate 420 is used to contact the concrete formwork 100 and transmit vibration. The third laser rangefinder 430 is arranged at the top of the vertical track 330, and the laser direction faces the concrete formwork 100. The fourth laser rangefinder 440 is mounted on the side of the auxiliary plate 420, and the laser direction faces the vertical track 330. When the measurement results of the third laser rangefinder 430 and the fourth laser rangefinder 440 reflect that the auxiliary plate 420 is in a fitting state with the concrete formwork 100, the vibration mode of the vibrator 410 can be turned on.

[0037] The main control module 500 is signal-connected to the temperature sensor 230, the first laser rangefinder 280, the second laser rangefinder 370, the third laser rangefinder 430, the fourth laser rangefinder 440, the vertical traveling device 340, the lateral support device 350, the auxiliary support device 360, and the vibrator 410. In this embodiment, wireless network transmission can be used for signal transmission, so as to realize the automatic detection and control of the whole device.

[0038] The present invention can realize the automatic formwork vibration of concrete construction, solve the technical difficulties of uneven manual vibration, large safety hazards, and low automation degree, realize the automatic and unmanned vibration or vibration of concrete construction, enhance the concrete density, improve the quality of concrete pouring construction, avoid phenomena such as honeycombing and pockmarking of concrete, improve work efficiency, and promote the efficient operation of the project.

[0039] In some embodiments, the concrete pouring height positioning system 200 is arranged and operates as follows: The threaded steel bars 220 and the smooth round steel bars 240 are vertically and fixedly tied at equal intervals from top to bottom on the steel reinforcement cage of the concrete column to be poured. A temperature sensor 230 is fixedly installed at equal intervals of 10 cm from bottom to top on the threaded steel bar 220. At this time, the temperature sensors 230 are vertically arranged in the area of the concrete to be poured, and the temperature sensors 230 are numbered and bound in advance, and the height corresponding to the position of each temperature sensor 230 relative to the bottom plate is set. The temperature sensors 230 are externally connected to the acquisition and transmission module, and the temperature data of each temperature sensor 230 are sent to the main control module 500 in real time. Before the concrete pouring construction, the current temperatures of all the temperature sensors 230 are measured in advance as the initial temperatures and sent to the main control module 500. When the concrete pouring construction is carried out, the temperature changes of all the temperature sensors 230 are monitored in real time. Suppose the numbers of the temperature sensors 230 are #1, #2, #3... #n from bottom to top in sequence, and the corresponding heights are h1, h2, h3... hn; when the main control module 500 receives that the temperature of the #1 temperature sensor 230 changes suddenly and shows an increasing trend in a very short time, and the temperatures of the #2 and above temperature sensors 230 do not fluctuate significantly, it means that the concrete 101 covers the bottommost #1 temperature sensor 230. At this time, it can be judged that the concrete pouring height changes around h1; when the main control module 500 receives that the temperature of the #2 temperature sensor 230 changes suddenly and shows an increasing trend in a very short time, and the temperatures of the #3 and above temperature sensors 230 do not fluctuate significantly, it means that the concrete 101 has covered the #2 temperature sensor 230. At this time, it can be judged that the concrete pouring height changes around h2; and so on, the approximate height range of the concrete pouring height can be quickly and preliminarily positioned.

[0040] Meanwhile, since the density of the buoy board 250 is less than that of the concrete 101, in this embodiment, the buoy board 250 is designed as a cuboid with a certain thickness and hardness. A circular buckle 270 is fixedly installed at the end of the buoy board 250. The circular buckle 270 is designed as a cylinder with a central opening. The inner wall of the hole is smooth, and the opening size matches the diameter of the smooth round steel 240. The smooth round steel 240 passes through the inner wall of the central hole of the circular buckle 270 to achieve the movable connection between the smooth round steel 240 and the circular buckle 270. At this time, there is a lateral limit between the buoy board 250 and the smooth round steel 240, so that it will not slide laterally with the concrete pouring. A reflection disc 260 is vertically fixed at the top of the smooth round steel 240, and the center of the reflection disc 260 coincides with the center of the cross-section of the smooth round steel 240. A first laser rangefinder 280 is fixedly installed on the surface of the buoy board 250, and the ranging direction of the first laser rangefinder 280 faces the reflection disc 260. Before the concrete pouring, in the initial state, the buoy board 250 is at the bottom position of the smooth round steel 240. At this time, the height of the buoy board 250 is the thickness of the spacer 210, assumed to be a. The distance between the buoy board 250 and the reflection disc 260 is measured in advance, assumed to be L1. After the concrete is poured, the buoy board 250 floats with the concrete surface as the concrete is poured. The first laser rangefinder 280 monitors the distance between the buoy board 250 and the reflection disc 260 in real time, assumed to be L2, and sends the distance information to the main control module 500. Assume the height of the buoy board 250 is f. At this time, the height f of the buoy board 250 = L1 - L2 + a, that is, the concrete pouring height is f minus the thickness of the buoy board 250.

[0041] When the temperature sensor 230 monitors that a certain sensor corresponding height is covered, the distance between the buoy board 250 and the reflection disc 260 is measured in time through the first laser rangefinder 280, and the concrete pouring height is further calculated. At this time, it can be verified whether it is within the deviation range interval through the two height monitoring results. At this time, the concrete pouring height position can be quickly judged to achieve the positioning of the concrete pouring height.

[0042] In some embodiments, please refer to Figure 1 and Figure 2, the horizontal rails 310 are symmetrically arranged above and below the top and bottom of the concrete formwork 100, symmetrically arranged horizontally along the upper and lower edges of the concrete formwork 100. The horizontal rails 310 are in the shape of a cuboid strip, with the back surface fixedly connected to the concrete formwork 100, and the front surface is designed with a C-shaped opening. Horizontally sliding bolts 320 are symmetrically installed inside the upper and lower horizontal rails 310. The cross-sectional dimension of the horizontally sliding bolt 320 is larger than the size of the C-shaped opening on the front of the horizontal rail, so that the horizontally sliding bolt 320 is always inside the horizontal rail 310. A vertical rail 330 is connected between the two horizontally sliding bolts 310. The horizontally sliding bolt 320 and the vertical rail 330 are fixedly connected by a connecting rod 331. One end of the connecting rod 331 is perpendicularly fixed to the horizontally sliding bolt 320, and the other end passes through the C-shaped opening of the horizontal rail 310 and is perpendicularly fixedly connected to the end of the vertical rail 330.

[0043] In some embodiments, please refer specifically to Figure 3 , and in combination with Figure 1 and Figure 2 , the horizontally sliding bolt 320 slides along the horizontal rail 310 through a transverse movement unit 380. The transverse movement unit 380 includes a rotation control actuator motor 381, a wire winding disc 382, a concentric rotating shaft 383, and a wire 384. The rotation control actuator motor 381 is symmetrically installed on the inner side wall of the upper surface at one end and the inner side wall of the lower surface at the other end of the horizontal rail 310. The center of the rotating shaft of the rotation control actuator motor 381 is connected to the concentric rotating shaft 383. The wire winding disc 382 is fixedly nested on the concentric rotating shaft 383. The wire 384 is wound around the wire winding disc 382, and the other end of the wire 384 is fixedly connected to the horizontally sliding bolt 320. Specifically, when the rotation control actuator motor 381 rotates, it can drive the wire winding disc 382 to rotate synchronously. The rotation of the wire winding disc 282 can wind or relax the wire 384, thereby driving the horizontally sliding bolt 320 to perform a sliding operation. When the rotation control actuator motor 381 at one end performs a clockwise rotation operation, the wire winding disc 382 on this side rotates synchronously to wind and take up the wire, and the rotation control actuator motor 381 at the other end performs the opposite wire releasing operation, thereby realizing the horizontal sliding movement of the horizontally sliding bolt 320 and driving the vertical rail 330 fixedly connected thereto to perform a horizontal sliding movement.

[0044] In some embodiments, please refer specifically to Figure 4, the cross-section of the vertical track 330 is C-shaped, and the opening direction faces the concrete formwork 100. The vertical track 330 is also strip-shaped and has a single-sided C-shaped opening design like the horizontal track 310, but the opening direction faces the concrete formwork 100. In some embodiments, a fifth laser rangefinder 332 is installed at the bottom end of the vertical track 330, and the laser direction is directly opposite to the connection position of the next concrete formwork 100. By monitoring the change in the distance between the vertical track 330 and the vertical side edge of the concrete formwork 100 in real time, the lateral position positioning of the vertical track 330 can be achieved.

[0045] In some embodiments, please refer with emphasis to Figure 4 and Figure 5 , the vertical traveling device 340 includes a vertical traveling main control platform 341, a connection mounting plate 342, a traveling control motor actuator 343, a rotating shaft 344, a synchronous running leather belt 345, and four synchronous limiting wheels 346. The vertical traveling main control platform 341 is located inside the vertical track 330, and the sides are in contact with the inner wall of the vertical track 330 by using the synchronous limiting wheels 346 respectively; the traveling control motor actuator 341 is fixed to the vertical traveling main control platform 341 through the connection mounting plate 342; the central rotating shaft of the traveling control motor actuator 343 is fixedly connected to the rotating shaft 344 and rotates synchronously; the rotating shaft 344 drives the synchronous limiting wheels 346 to rotate synchronously by using the synchronous running leather belt 345, so as to realize the movement of the vertical traveling device 340 along the vertical track 330.

[0046] In this embodiment, please continue to refer to Figure 4 and Figure 5 , the vertical traveling main control platform 341 is designed as a cuboid, and 4 groups of synchronous limiting wheels 346 are symmetrically installed at the front and back positions facing the vertical track 330 respectively. The connection mounting plate 342 is arranged inside the vertical traveling main control platform 341. One end of the connection mounting plate 342 is fixedly connected to the vertical traveling main control platform 342, and the other end is fixedly installed with the traveling control motor actuator 343. The central rotating shaft of the traveling control motor actuator 343 is fixedly connected to the rotating shaft 344 and rotates synchronously. When the traveling control motor actuator 343 performs a clockwise rotation operation, the rotating shaft 344 can be driven to perform a clockwise rotation operation synchronously. For the convenience of description, the rotating shaft 344 is divided into a main control rotating shaft 344a and a synchronous rotating shaft 344b, and the synchronous limiting wheels 346 are divided into a first synchronous limiting wheel 346a, a second synchronous limiting wheel 346b, a third synchronous limiting wheel 346c, and a fourth synchronous limiting wheel 346d, and their distribution is as Figure 4 and Figure 5As shown. Specifically, large and small synchronous rotation shafts are evenly distributed on the first synchronous limit wheel 346a and the second synchronous limit wheel 346b. The third synchronous limit wheel 346c is provided with large synchronous rotation shafts, and the fourth synchronous limit wheel 346d is provided with small synchronous rotation shafts. The size of the large rotation shaft is the same as that of the main control rotation shaft 344a, and the size of the small rotation shaft is the same as that of the synchronous rotation shaft 344b. The main control rotation shaft 344a and the large rotation shaft on the first synchronous limit wheel 346a are connected by a synchronous operation leather belt 345. The small rotation shafts on the first synchronous limit wheel 346a and the second synchronous limit wheel 346b are connected by a synchronous operation leather belt 345. The large rotation shafts on the second synchronous limit wheel 346b and the third synchronous limit wheel 346c are connected by a synchronous operation leather belt 345. The small rotation shaft on the fourth synchronous limit wheel 346d and the synchronous rotation shaft 344b are connected by a synchronous operation leather belt 345. When the walking control motor actuator 343 receives an instruction from the main control module 500 to perform a rotation operation, it drives the main control rotation shaft 344a and the synchronous rotation shaft 344b to rotate synchronously, and further drives the four synchronous limit wheels 346 to rotate synchronously, so as to realize the vertical walking of the vertical walking device 3340.

[0047] In some embodiments, please continue to refer to Figure 4 and Figure 5 , the lateral support device 350 has eight groups, which are respectively arranged on two opposite sides of the vertical walking main control platform 341. Each group of the lateral support device 350 includes a lateral support oil cylinder controller 351, a lateral support oil cylinder sleeve 352, a lateral support oil cylinder piston telescopic rod 353 and a support pad 354. The lateral support oil cylinder controller 351 is fixed inside the vertical walking main control platform 341; one end of the lateral support oil cylinder sleeve 352 is fixedly connected to the lateral support oil cylinder controller 351, and the other end is movably connected to the lateral support oil cylinder piston telescopic rod 353; the other end of the lateral support oil cylinder piston telescopic rod 353 is connected to the support pad 354, and the support pad 354 is used to contact the inner wall of the vertical track 330. When the vertical walking device 340 runs to the designated position, after all 8 groups of lateral support oil cylinder controllers 351 receive the stop and fixation instruction issued by the main control module 500, they perform a stretching operation, driving the corresponding lateral support oil cylinder piston telescopic rods 353 to stretch outwards, and further driving the support pad 354 to move towards the side wall of the vertical track 330 until it tightly abuts against the side wall.

[0048] In some embodiments, please continue to refer to Figure 4, the vibrator 410 is installed on the vertical walking main control platform 341 and is located at the opening of the vertical track 330. That is to say, the vertical walking main control platform 341 is fixedly installed with the vibrator 410 right in the middle of the opening of the vertical track 330, and is fixedly connected to the bottom surface of the vibrator 410, which can not only drive the vibrator 410 to perform vertical walking by the vertical walking device 340, but also does not affect the contact between the vibrator 410 and the lateral concrete formwork 100.

[0049] In some embodiments, please refer with emphasis to Figure 4 , the auxiliary support device 360 is installed on two sides of the vibrator 410, and respectively includes an auxiliary support oil cylinder controller 361, an auxiliary support oil cylinder sleeve 362, an auxiliary support oil cylinder piston telescopic rod 363 and a limit clamping seat 364; the auxiliary support oil cylinder controller 361 is installed on two side surfaces of the vibrator 410, one end of the auxiliary support oil cylinder sleeve 362 is fixedly connected to the auxiliary support oil cylinder controller 361, and the other end is movably connected to the auxiliary support oil cylinder piston telescopic rod 363; the other end of the auxiliary support oil cylinder piston telescopic rod 363 is connected to the limit clamping seat 364; the limit clamping seat 364 is designed in a side U shape, and the U-shaped opening faces the side edge of the opening of the vertical track 330. When the vertical walking device 340 runs to the specified position, after the auxiliary support oil cylinder controller 361 receives the stop fixing instruction issued by the main control module 500, it performs a stretching operation, drives the auxiliary support oil cylinder piston telescopic rod 363 to stretch outwards, and further drives the limit clamping seat 364 to move towards the side edge of the opening of the vertical track 330 until it tightly abuts against the opening side edge. At this time, the temporary fixation between the vertical walking device 340 and the vertical track 330 can be realized.

[0050] In some embodiments, second laser rangefinders 370 are respectively installed at the bottom positions of the vertical walking main control platforms 341 in the two groups of vertical walking devices 340, and the laser directions are towards the bottom positions. The second laser rangefinder 370 located below can real-time monitor the distance between the lower vertical walking device 340 and the bottom surface of the vertical track 330, assumed to be m; the second laser rangefinder 370 located above can real-time monitor the distance between the two vertical walking devices 340, assumed to be n, and assume the length of the lower vertical walking device 340 is d. At this time, the approximate height of the upper vertical walking device 340 can be calculated, which is m + n + d, to realize the vertical position positioning of the vertical walking device 340. In application, the upper vertical walking device 340 is mainly used for positioning and tracking the current concrete pouring part, and the lower vertical walking device 340 is mainly used for positioning the middle position of the already poured concrete.

[0051] In some embodiments, in the vibration system 400, an oil cylinder controller 411 is mounted on the front of the vibrator 410. One end of the oil cylinder sleeve 412 is fixedly connected to the oil cylinder controller 411, and the other end is movably connected to the oil cylinder piston telescopic rod 413. The other end of the oil cylinder piston telescopic rod 413 is connected to an auxiliary plate 420. After receiving the vibration preparation instruction issued by the main control module 500, the oil cylinder controller 411 performs a stretching operation, driving the oil cylinder piston telescopic rod 413 to stretch outwards, further driving the auxiliary plate 420 to move towards the concrete formwork 100 until it tightly abuts against the concrete formwork 100. At this time, the vibrator 410 forms a temporary connection with the concrete formwork 100. When the vibrator 410 vibrates, the corresponding concrete formwork 100 at this place is driven to vibrate, thereby improving the construction quality of the concrete.

[0052] Specifically, a fourth laser rangefinder 440 is installed on the side of the auxiliary plate 420, and the laser direction faces the vertical track 330, which is used to monitor the distance between the auxiliary plate 420 and the vertical track 330 in real time. A third laser rangefinder 430 is arranged at the top end of the vertical track 330, and the laser direction faces the concrete formwork 100, which is used to monitor the distance between the vertical track 330 and the concrete formwork 100 in real time. When the vertical traveling device 340 runs to the designated position and is temporarily fixed, the main control module 500 issues a monitoring instruction to the third laser rangefinder 430 and the fourth laser rangefinder 440. After receiving the instruction, the fourth laser rangefinder 440 measures the distance between the auxiliary plate 420 and the vertical track 330 (assumed to be x), and the third laser rangefinder 430 measures the distance between the vertical track 330 and the concrete formwork 100 (assumed to be y) after receiving the instruction and feeds it back to the main control module 500. After receiving the feedback, the main control module 500 compares the distances. If x < y, it means that the auxiliary plate 420 and the concrete formwork 100 are not in a fitting state, then the main control module 500 issues a vibration preparation instruction to the oil cylinder controller 411. After receiving the instruction, the oil cylinder controller 411 performs the corresponding stretching operation, and at the same time, the third laser rangefinder 430 and the fourth laser rangefinder 440 monitor the distance information in real time and feed it back to the main control module 500 until x = y, indicating that the auxiliary plate 420 and the concrete formwork 100 are in a fitting state, and the formwork vibration operation can be entered, thereby realizing the automatic formwork vibration function during concrete construction.

[0053] The present invention also provides a use method of the concrete density vibration formwork device as described above, including the following steps:

[0054] Step 1: After the assembly of each component is completed, use the concrete formwork 100 for concrete pouring;

[0055] Step 2: During the pouring process, the relative pouring height of the concrete 101 is identified based on the temperature change pattern when the temperature sensor 230 is covered by the concrete 101. Meanwhile, the height deviation is verified by the first laser rangefinder 280 on the buoy board 250, and the real-time monitoring information is fed back to the main control module 500.

[0056] Step 3: After receiving the concrete height feedback information, the main control module 500 issues a height ranging command to the second laser rangefinders 370 on the two sets of vertical walking devices 340, and feeds the monitoring information back to the main control module 500. The main control module 500 determines whether the upper vertical walking device 340 is at the concrete pouring height position and whether the lower vertical walking device 340 is at the middle position of the already poured concrete based on the feedback information, and feeds the monitoring information back to the main control module 500. If the vertical walking device 340 does not reach the designated position, the main control module 500 issues a walking instruction to the walking control motor actuator 343. The walking control motor actuator 343 performs the corresponding operation, and at the same time, the second laser rangefinder 370 monitors the height in real time until the walking control motor actuator 343 reaches the designated position. The main control module 500 issues a fixing instruction to the lateral support device 350 and the auxiliary support device 360. The lateral support oil cylinder controller 351 and the auxiliary support oil cylinder controller 361 perform the corresponding operations to form a temporary fixation between the vertical walking device 340 and the vertical track 330, and feed the fixation information back to the main control module 500.

[0057] Step 4: After receiving the temporary fixation information between the walking control motor actuator 343 and the vertical track 330, the main control module 500 issues a ranging instruction to the fifth laser rangefinder 332 to determine the lateral positioning of the vertical track 330 in the concrete formwork 100. After receiving the instruction, the fifth laser rangefinder 332 monitors the lateral distance and feeds it back to the main control module 500. The main control module 500 issues a lateral positioning adjustment instruction to the rotation control execution motor according to the feedback information. After receiving the instruction, the rotation control execution motor 381 performs the corresponding operation and feeds it back to the main control module 500. The lateral positioning is carried out at every 1-meter interval starting from the lateral edge of the concrete formwork 100.

[0058] Step 5: After each lateral positioning, the main control module 500 issues a ranging command to the fourth laser rangefinder 440 on the auxiliary board 420 to determine whether the auxiliary board 420 and the concrete formwork 100 are in a fitting state, and feeds back the result to the main control module 500. After receiving the feedback information, the main control module 500 issues an adjustment command to the oil cylinder controller 411. At the same time, the third laser rangefinder 430 monitors the distance between the auxiliary board 420 and the concrete formwork 100 in real time until the auxiliary board 420 and the concrete formwork 100 are completely in a fitting state. The main control module 500 issues a vibration command to the vibrator 410, and the vibrator 410 executes the operation to drive the concrete formwork 100 to vibrate. In this way, it vibrates once every 1 meter horizontally in a reciprocating manner, thereby improving the construction quality of the concrete and reducing or avoiding concrete quality problems such as honeycombing and pockmarks.

[0059] Of course, the vibrators 410 on the two sets of vertical traveling devices 340 can be set with different vibration frequencies according to the state information (in-situ casting, casting duration, etc.) of the concrete 101 at the corresponding positions to achieve different vibration effects.

[0060] In summary, the concrete density vibration formwork device and its use method provided by the present invention can realize automatic formwork vibration during concrete construction, solve the technical problems of uneven manual vibration, large safety hazards, and low automation degree, realize automatic and unmanned vibration or vibration during concrete construction, enhance the concrete density, improve the construction quality of concrete pouring, avoid phenomena such as concrete honeycombing and pockmarks, improve work efficiency, and promote the efficient operation of the project.

[0061] Obviously, those skilled in the art can make various changes and modifications to the invention without departing from the spirit and scope of the invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalent technologies, the present invention is also intended to include these changes and modifications.
