Description

TECHNICAL FIELD

[0001] The present invention relates to a concrete leveling vibratory apparatus that inserts a vibrator into placed concrete, and a construction system using the same.

BACKGROUND ART

[0002] Future warehouses require automation such as AGVs (Automated Guided Vehicles) and automated forklifts, and the floor precision requirements for this purpose are increasing year by year. In order to meet such requirements, concrete leveling work performed before placed concrete hardens becomes a critical operation.

[0003] That is, defects such as bleeding where water floats on the concrete surface and cracks after concrete hardening are highly likely to occur due to insufficient water removal, air removal, void elimination, etc. inside the concrete. For this reason, construction workers perform compaction work by inserting a rod-shaped vibrator into the placed concrete and pulling out the inserted rod-shaped vibrator after a predetermined time has elapsed. Conventionally, this compaction work was performed by construction workers holding the rod-shaped vibrator themselves (see Patent Document 1).

SUMMARY OF THE INVENTION

PROBLEMS TO BE SOLVED BY THE INVENTION

[0005] However, in the conventional example described above, since construction workers need to directly handle the rod-shaped vibrator, the compaction work such as air removal, water removal, and void elimination by inserting the vibrator into the concrete was extremely cumbersome.

[0006] In particular, the insertion of the rod-shaped vibrator into the concrete floor surface had to be done at numerous points, for example, at 60cm intervals, both vertically and horizontally. This made it a physically demanding and time-consuming task for the workers.

[0007] Therefore, the present invention aims to provide a concrete leveling vibrator and a construction system using the same, which can facilitate compaction work by inserting a vibrator into concrete. [Means for solving the problem]

[0008] The present invention has been made in view of the above problems, and is a concrete leveling vibrator comprising: a vibrator body; a running wheel attached to the vibrator body; a main arm whose base end is supported by the vibrator body and which extends outward from the vibrator body; a vibrator attached to the tip of the main arm; a vibrator lifting mechanism for moving the vibrator in the vertical direction; and a motor for vibrator for vibrating the vibrator.

[0009] Another invention is a construction system characterized by comprising the above-mentioned concrete leveling vibrator, in which all or the main drive systems are configured to be controllable; a control device capable of controlling the concrete leveling vibrator; and a worker terminal capable of sending commands to the control device. [Effects of the Invention]

[0010] According to the present invention, compaction work can be easily performed by inserting a vibrator into the concrete. [Brief explanation of the drawing]

[0014] Hereinafter, an embodiment will be described in detail with reference to the accompanying drawings. In this embodiment, descriptions of already known techniques are omitted. In addition, this is an illustration of apparatuses and methods for embodying the technical idea of the present invention, and the technical idea of the present invention is not limited to the following contents. The technical idea of the present invention can be modified in various ways within the scope of the matters stated in the claims. In particular, it should be noted that the drawings are schematic and may differ from actual implementations.

[0015] (Construction Method for Concrete Floor Surface) For the construction of a concrete floor surface, as an example, the following steps are performed: placing and leveling step, laser screed step, level confirmation step, re-vibration compaction step, disc troweling step, blade pressing step, metal trowel finishing step, and curing step.

[0016] In the concrete placement and leveling process, a concrete floor surface is constructed at the construction site, such as a warehouse, and ready-mix concrete is poured into this area. The poured concrete is roughly leveled to a general level using a raking rod or similar tool. Then, a rod-shaped vibrator is inserted into the poured concrete to compact it. In the laser screed process, the level of the concrete floor surface is monitored using a laser beam, and the concrete surface is leveled by applying vertical vibrations to the surface of the concrete floor. In the level confirmation process, the level of the leveled concrete floor surface is confirmed. In the re-vibration compaction process, after a predetermined time has elapsed since the level confirmation, based on the measurement results from the bleeding measurement device, vibrations are applied to the concrete surface with a vibrating blade or a rod-shaped vibrator is inserted into the concrete to re-compact it as needed. In the disc setting process, the surface of the concrete floor surface is finished using a rotating disc of the first rotary drive machine. In the wing trowel setting process, the surface of the concrete floor surface is finished using a wing-shaped rotary trowel of the second rotary drive machine. In the trowel finishing process, the surface of the concrete floor surface is finished using a trowel by a plasterer as needed.

[0017] One embodiment of the concrete leveling vibrator 1 can be used in a concrete placement and leveling process or a re-vibration compaction process that uses a rod-shaped vibrator for compaction. A detailed explanation follows below.

[0018] (Configuration of the concrete leveling vibrator 1) Figures 1 to 19 show one embodiment of the present invention. As shown in Figures 1 to 4, the concrete leveling vibrator 1 comprises a vibrator body 2, a traveling wheel 3 attached to the vibrator body 2, a main arm 4 supported by the vibrator body 2, a pair of sub-arms 5 attached to the tip of the main arm 4, three rod-shaped vibrators 6 attached to the tip of the main arm 4 and to each of the sub-arms 5, a vibrator lifting mechanism 20, a sub-arm forward and backward movement mechanism 30, and a vibrator motor 7. The names of the tip and base of the main arm 4 refer to the positions of the main arm 4 as seen from the position of the operator.

[0019] The vibration device body 2 is enclosed in a housing 2a and is approximately rectangular in shape. The lower part of the front of the housing 2a protrudes forward, and the upper part of the front of the housing 2a is a vertical surface. The running wheels 3 are mounted below the bottom surface of the vibration device body 2. A pair of running wheels 3 are mounted at the front and rear positions of the vibration device body 2, for a total of four locations. The running wheels 3 rotate in forward and reverse directions using a driving motor (not shown) as the drive source.

[0020] As shown in detail in Figure 5, the main arm 4 is attached to the vibrator body 2 so that its base end can rotate vertically around a rotation support pin (not shown) as the center of rotation. The tip of the main arm 4 extends outward toward the front of the vibrator body 2.

[0021] As shown in detail in Figures 6 and 7, the tip of the main arm 4 is provided with a link plate 10, a pair of sub-arm support members 11, and a main arm extension member 12. The link plate 10 is rotatably connected to the main arm 4 and the parallel link member 26 (described below) by rotation support pins 27.

[0022] A pair of sub-arm support members 11 are fixed to the front surface of the link plate 10. Between the pair of sub-arm support members 11, a component housing space 11A is formed, with the front side open.

[0023] The main arm extension member 12 is fixed to the link plate 10 within the component housing space 11A of the pair of sub-arm support members 11. The main arm extension member 12 has an auxiliary arm portion 12a that extends in the same direction as the main arm 4, and a vibrator mounting portion 12b fixed to the tip of the auxiliary arm portion 12a.

[0024] The pair of sub-arms 5 are rotatably supported at their base ends at both ends of the chain link member 36 described below. The specific fixing structure is described below. The tip ends of the pair of sub-arms 5 extend from the main arm 4 in different left-right directions (the reference direction is perpendicular to the main arm 4). The tip of each sub-arm 5 is a free end.

[0025] The three vibrators 6 are each attached by a vibrator mounting portion 12b on the main arm extension member 12 and two vibrator mounting portions 13 attached to a pair of sub-arms 5. Each vibrator 6 vibrates when an eccentric pendulum (not shown) housed inside rotates due to the rotation from the vibrator motor 7.

[0026] As shown in detail in Figure 7, the vibrator mounting portion 13 of the sub-arm 5 is slidably provided on the sub-arm 5 and can be attached to any position on the sub-arm 5. In other words, the mounting position of the vibrator 6 on the sub-arm 5 is adjustable.

[0027] A vibrator motor 7 is mounted on the upper surface of the vibrator mounting portion 13 of the sub-arm 5. A motor cover 14 is attached to the vibrator motor 7. A mounting cylindrical portion 13a having a fitting lock portion (not shown) inside is provided at the lower part of the vibrator mounting portion 13 of the sub-arm 5. The vibrator 6 is attached to the vibrator mounting portion 13 by screw fastening the mounting cylindrical portion 13a and the mounting portion 6b of the support shaft 6a of the vibrator 6. The vibrator motor 7 and vibrator 6 are similarly attached to the vibrator mounting portion 12 on the main arm extension member 12 side (center position side). It is preferable to attach a vibration damping member (for example, made of rubber) 15 to the vibrator motor 7, as shown in Figures 7(b) and 7(c).

[0028] In other words, each vibrator motor 7 and each vibrator 6 are detachably mounted on the main arm extension member 12 and the sub-arm 5. Therefore, it is possible to mount only the central vibrator 6, or any two of the three vibrators 6, or all three vibrators 6. The drawing of this embodiment shows the state in which all three vibrators 6 are mounted.

[0029] Furthermore, as shown in Figure 8(a), the tip of the main arm 4 is detachably provided between the link plate 10 and a pair of sub-arm support members 11. This allows the part attached to the tip of the link plate 10 to be replaced with a different configuration. For example, the A-type assembly 5A with a sub-arm 5 of length L1 shown in Figure 8(a) can be replaced with the B-type assembly 5B with a sub-arm 5 of length L2 shown in Figure 8(b).

[0030] The vibrator lifting mechanism 20 (shown in Figures 1 and 5) is a mechanism that simultaneously moves the three rod-shaped vibrators 6 in the vertical direction while holding them vertically. The vibrator lifting mechanism 20 includes a main arm rotation mechanism 21 that rotates (moves) the tip of the main arm 4 in the vertical direction, and a vibrator vertical holding mechanism 25 that holds the vibrators 6 in the vertical direction without changing the orientation of the link plate 10, a pair of sub-arm support members 11, and main arm extension member 12, which are rotatably attached to the tip of the main arm 4.

[0031] The main arm rotation mechanism 21 is equipped with an electrically operated actuator 22. The actuator 22 is rotatably supported, with the actuator body 22a on the front of the vibrator body 2 and the output rod 22b of the actuator 22 on the underside of the main arm 4. The output rod 22b extends and retracts due to the driving force of the actuator 22, causing the main arm 4 to rotate around a rotation support pin (not shown), thereby moving the tip of the main arm 4 and a pair of sub-arms 5 in the vertical direction.

[0032] As shown in detail in Figure 6, the vibrator vertical holding mechanism 25 has a pair of parallel link members 26 positioned on the left and right sides of the main arm 4. Each parallel link member 26 is positioned parallel to the main arm 4. Each parallel link member 26 is rotatably connected at one end to the housing 2a of the vibrator body 2 and at the other end to the link plate 10.

[0033] In other words, the main arm 4, the parallel link members 26, the link plate 10, and the housing 2a of the vibrator body 2 constitute a practical parallel link mechanism. As a result, when the main arm 4 rotates, the pair of parallel link members 26 move in parallel to follow the rotation of the main arm 4, but the orientation of the link plate 10 (the front surface of the link plate 10 remains vertical) does not change, and the three vibrators 6 always maintain a vertical orientation.

[0034] The sub-arm forward and backward movement mechanism 30, as shown in detail in Figures 9 to 11, is a mechanism that moves the tip of each sub-arm 5 horizontally and moves the two vibrators 6 of the sub-arm 5 in the forward and backward direction (near and far direction) relative to the vibration device body 2. The sub-arm forward and backward movement mechanism 30 comprises a rotating lever 31 (shown in Figure 5, etc.), a relay rod 32 that rotates around an axis by the rotation of the rotating lever 31, a ball screw 34 connected to the tip of the relay rod 32 via a universal joint 33, a nut member 35 screwed into the ball screw 34, and a chain link member 36 rotatably connected to the tip of the ball screw 34.

[0035] The nut member 35 is positioned in a non-rotatable manner within the component housing space 11A of the pair of sub-arm support members 11, and is linearly movable within the component housing space 11A only by the pitch of the ball screw 34. The chain link member 36 consists of five link components 36a to 36e that are rotatably connected to each other in a line. The tip of the ball screw 34 is rotatably connected to the central link component 36c of this chain link member 36. The link components 36a and 36e at both ends of the chain link member 36 are rotatably supported by the pair of sub-arm support members 11, respectively, by rotation support pins 37.

[0036] In the sub-arm forward and backward movement mechanism 30, when the nut member 35 moves linearly based on the pitch of the ball screw 34, the position of the link component 36c at the center of the chain link member 36 shifts, and this shift changes the orientation of the link components 36a and 36e at both ends of the chain link member 36. Then, following the change in orientation of the link components 36a and 36e at both ends, each sub-arm 5 rotates horizontally, and the tip of each sub-arm 5 moves in the forward and backward direction relative to the vibration device body 2. The pair of sub-arms 5 can be displaced to typical positions such as the close position shown in Figure 9, the intermediate position shown in Figure 10, and the distant position shown in Figure 11. Displacement to other positions is also possible.

[0037] As shown in Figure 5, three wire harnesses 40 are routed from the main body 2 of the vibrator device along the main arm 4. One of these is routed to the vibrator mounting portion 12b on the main arm extension member 12 side (central position side), and the other two are routed to the respective vibrator mounting portions 13 of the pair of sub-arms 5. The wire harnesses 40 are fastened to the sub-arms 5, etc., by harness clips 41. Power from the battery 55 described below is supplied to each vibrator motor 7 via the wire harnesses 40.

[0038] As shown in detail in Figure 12, a steering handle 45 is attached to the rear side of the vibration device body 2. Various operating parts are provided on this handle 45 and on the vibration device body 2 near the handle 45. The rotary lever 31 is located on the top surface of the vibration device body 2. At the rotation center of the handle 45 are vibrator switches (left, center, right) 47, a power indicator lamp 48, and a vibrator start / stop switch 49. Below the handle 45 on the vibration device body 2 are an emergency stop switch 50 and an on / off & speed volume adjustment button 51. The right-hand grip of the handle 45 is equipped with a forward / stop / reverse switch 52 and a throttle trigger 53. The left-hand grip of the handle 45 is equipped with a vibrator height adjustment lever 54. As shown in Figure 13, a battery 55 is housed inside the rear of the vibration device body 2.

[0039] Next, the power transmission system from the handle 45 to the running wheels 3 will be described. As shown in Figures 14 and 15, the handle 45 is rotatably supported on a support shaft 60. A first gear 61 is fixed to the lower end of the support shaft 60, and a second gear 62 meshes with the first gear 61. The second gear 62 is coaxially and integrally provided with the third gear 63. A chain 67 is stretched between the third gear 63 and the fourth gear 64, which is positioned above the running wheels 3, via a path that also includes two auxiliary gears 65 and 66. The rotational support shaft 64a of the fourth gear 64 is fixed to the support arm 68 of the running wheels 3. When the handle 45 is rotated, this rotational force rotates the support arm 68, changing the direction of the running wheels 3.

[0040] Next, with reference to Figure 16, the stability of the concrete leveling vibrator 1 based on its overturning stability ratio (degrees) will be explained. As shown in Figure 16(b), the stability of the crane 69 is indicated by the value of (stabilizing moment) / (overturning moment). As shown in Figure 16(a), the overturning fulcrum of the concrete leveling vibrator 1 is the center of the front traveling wheel 3. The moment acting on the vibrator body 2 side from the center of this traveling wheel 3 is the stabilizing moment, and the moment acting on the vibrator 6 side from the center of the traveling wheel 3 is the overturning moment. As a result, the stability is (68 kg × 0.457) / (44 kg × 0.59) = 1.2. Therefore, the concrete leveling vibrator 1 has a good overturning stability ratio (degrees), and is structured so that it will not easily overturn even when the three vibrators 6 are moved by the traveling wheel 3 in a hollow position.

[0041] Next, we will explain how the concrete leveling vibrator 1 can be made more compact. As shown in Figures 17 to 19, in order to make the concrete leveling vibrator 1 more compact, the three vibrators 6 are removed from the concrete leveling vibrator 1. Next, the main arm 4 is folded into the vibrator body 2. Also, the vibrator mounting portion 13 and vibrator motor 7 of each sub-arm 5 are moved to the base end side of the sub-arm 5 and fixed, and each sub-arm 5 is folded by bringing its tip closer to the vibrator body 2 side. Then, as shown in Figure 17(a), the rotating bracket 70 on the side of the vibrator body 2 is set to the deployed position (protruding position), and as shown in Figure 17(b), the three removed vibrators 6 are attached to the rotating bracket 70. Through these steps, the concrete leveling vibrator 1 can be made more compact.

[0042] When transporting the concrete leveling vibrator 1 by truck or other means, a pair of lifting hooks 71 are provided on the vibrator body 2, so a wire rope 72 from a crane or the like is attached to the pair of lifting hooks 71. This ensures that the lifting and lowering of the concrete leveling vibrator 1 can be carried out reliably, and the transportation of the concrete leveling vibrator 1 can be easily performed. Moreover, since the concrete leveling vibrator 1 can be transported in a compact form, it requires less space during transport. It is also excellent for storage and handling.

[0043] (Explanation of construction work using a vibrating device for concrete leveling) Next, the construction work using the concrete leveling vibrator 1 will be explained. For the concrete floor surface of the construction site, work will be performed using a rod-shaped vibrator at points, for example, at 60 cm intervals in both the longitudinal and transverse directions. The concrete leveling vibrator 1 uses three vibrators 6, with each sub-arm 5 positioned perpendicular to the main arm 4 (as shown in Figure 1), and the distance between each of the three vibrators 6 is set to 60 cm.

[0044] The operator moves the concrete leveling vibrator 1 and stops it when the three vibrators 6 are above the initial vibration point. Next, the operator turns on all the vibrator switches (left, center, right) 47 and operates the vibrator height adjustment lever 54 in the downward direction. The vibrator lifting mechanism 20 then operates, and the main arm 4 and the pair of sub-arms 5 gradually descend, inserting the three vibrators 6 into the concrete at a predetermined speed while vibrating. Once the vibrators 6 are inserted to a predetermined depth, they are vibrated at this depth for a predetermined time, and after the predetermined time has elapsed, the vibrator height adjustment lever 54 is operated in the upward direction, and the vibrators 6 are pulled out of the concrete at a predetermined speed. This vibration application operation into the concrete is performed a predetermined number of times (for example, once or multiple times).

[0045] Next, the operator moves the concrete leveling vibrator 1 60 cm forward or backward and stops it. At this stopping point, the vibration application operation described above is performed, and the operation is completed when this vibration application operation is performed at all vibration points. In addition, in order to meet the requirements of the JIS standard, the device is controlled to stop for at least 5 seconds at each vibration point.

[0046] (Effects of the embodiment) As described above, the concrete leveling vibrator 1 comprises a vibrator body 2, running wheels 3 attached to the vibrator body 2, a main arm 4 whose base end is supported by the vibrator body 2 and which extends toward the front (outside) of the vibrator body 2, a vibrator 6 attached to the tip of the main arm 4, a vibrator lifting mechanism 20 for moving the vibrator 6 in the vertical direction, and a vibrator motor 7 for vibrating the vibrator 6.

[0047] Therefore, since the vibrator 6 is mounted on a concrete leveling vibrator 1 that can be moved by the traveling wheels 3, there is no need for the construction worker to carry the vibrator 6 on the concrete floor. Since the vibrator 6 can be moved up and down by the vibrator lifting mechanism 20, there is no need for the construction worker to grasp the vibrator 6, insert it into the concrete, maintain the inserted state for a predetermined time, or pull it out. As a result, compaction work such as air removal and water removal can be easily performed by inserting the vibrator 6 into the concrete. This reduces the heavy labor of the construction worker and shortens the construction time.

[0048] The main arm 4 has a sub-arm 5 attached to its tip and extending in a different direction from the main arm 4. Vibrators 6 can be attached to both the tip of the main arm 4 and the sub-arm 5. Therefore, multiple vibrators 6 can be inserted into the concrete, allowing work to be performed at multiple locations at once and reducing working time.

[0049] The vibrator lifting mechanism 20 is designed to allow multiple vibrators 6 to move simultaneously in the vertical direction while maintaining their vertical orientation. Because each vibrator 6 is always facing vertically, each vibrator 6 can be smoothly inserted into the concrete, resulting in smoother work and reduced construction time. The vibrator lifting mechanism 20 is configured to raise and lower the tip of the main arm 4 by rotating it around the base end of the main arm 4. Therefore, even in construction sites with deep concrete cover (depth from the concrete surface to the reinforcing bars), the vibrator 6 can be inserted deeply by lowering the tip of the main arm 4 to a position close to the concrete floor, thus making it possible to work in such situations.

[0050] The sub-arms 5 are provided in pairs on the left and right sides from the tip of the main arm 4, and the tip of each pair of sub-arms 5 is provided so as to be movable in the front-rear direction relative to the vibrator body 2 by a sub-arm front-rear movement mechanism 30. Therefore, by changing the position of the vibrator 6 attached to the sub-arms 5 relative to the vibrator body 2, for example, to a far position or a near position, the concrete leveling vibrator 1 can be brought into the work area and work can be performed even if there are obstacles such as pillars in the work area, or even if there are narrow areas in the work area. Furthermore, the position of the vibrator 6 can be changed without moving the concrete leveling vibrator 1, improving work efficiency. In addition, the distance between the sub-arms 5 and other vibrators 6 can be changed by moving the sub-arms 5, making it easy to use and improving work efficiency. The distance between the vibrator 6 at the central position on the main arm 4 side, and the distance between the vibrators 6 attached to the pair of sub-arms 5 can also be changed by moving the sub-arms 5, improving work efficiency.

[0051] The vibrator 6 is designed so that the mounting position of the sub-arm 5 can be changed. Therefore, even if there are obstacles such as pillars in the construction work space, or if there are narrow areas in the construction work space, the concrete leveling vibrator 1 can be brought in and work can be performed. In addition, by changing the mounting position of the sub-arm 5, the distance between it and other vibrators 6 can be changed, making it easier to use and improving work efficiency.

[0052] The vibrator 6 is detachably mounted. Therefore, by removing the vibrator 6, the concrete leveling vibrator 1 can be made more compact, making it convenient for transporting, storing, and handling the concrete leveling vibrator 1. If the device can be fitted with multiple vibrators 6, as in one embodiment, the number and position of the vibrators 6 can be freely changed, making it easy to use.

[0053] The tip of the main arm 4 is detachable and can be replaced with a different type of part. Therefore, it can be replaced with parts according to the application, making it easy to use.

[0054] The sub-arm forward and backward movement mechanism 30 is configured to move the tip of each sub-arm 5 horizontally. Therefore, since the sub-arm 5 can be moved over the concrete of the construction work space with the vibrator 6 attached, work efficiency is improved and construction time is reduced. The main body 2 of the vibrating device is equipped with a lifting hook 71. Therefore, as described above, a wire rope 72 from a crane or the like can be attached to the lifting hook 71, allowing for stable and reliable lifting and lowering of the concrete leveling vibrating device. Furthermore, the concrete leveling vibrating device 1 can be easily transported. Moreover, the concrete leveling vibrating device 1 can be transported in a compact form. The concrete leveling vibrator 1 is equipped with a vibrator lifting mechanism 20 and a sub-arm forward / backward movement mechanism 3, which have the functions described above, making it a device that can meet diverse needs and is suitable for construction sites and civil engineering sites.

[0055] (Remote control installation, automated installation via programmed settings) Next, we will explain how the concrete leveling vibrator 1 can be operated remotely or automatically without human intervention using pre-set programming.

[0056] The remotely operated construction system comprises a concrete leveling vibrator configured to have all or major drive systems controllable, a control device capable of controlling the drive system within the concrete leveling vibrator, and a worker terminal capable of sending commands to the control device.

[0057] In a remotely operated construction system, the worker remotely controls the concrete leveling vibrator using a worker terminal while visually recognizing the vibrator. The worker then remotely controls the vibrator to perform the actions described above (Explanation of operation of the concrete leveling vibrator).

[0058] As shown in Figure 20, the unmanned, automated construction system 90, configured by a setting program, includes a concrete leveling vibrator 1A whose entire or major drive systems are controllable, a control device 91 that can communicate with and control the concrete leveling vibrator 1A, a work database 92 that can communicate with and supply data to the control device 91, and a worker terminal 93 which is an input device that can communicate with and input data to the control device 91.

[0059] The control device 91 has a CPU, ROM, RAM, etc., and is equipped with a communication unit. The control device 91 has a communication means 91a for sending and receiving data, a storage means 91b for storing data, an automatic command means 91c for commanding the concrete leveling vibrator 1 to automatically travel and perform automatic work, and an AI analysis means 91d for analyzing the data stored in the storage means 91b and / or the data accumulated in the work database 92 using artificial intelligence (AI).

[0060] The control device 91 and the concrete leveling vibrator 1 communicate with each other through identification vibrations, recognizing each other as they interact. The control program (firmware) executed by the concrete leveling vibrator 1 is stored in rewritable memory and is configured to be upgradeable at any time. Furthermore, it is not limited to the language of the control program (firmware).

[0061] The worker terminal 93 may be a remote controller that uses a known wireless communication method, or it may be a smartphone or tablet-type information terminal that can communicate with the control device 91 using an internet connection such as Wi-Fi, and has downloaded and stored an application linked to the control system program.

[0062] Furthermore, the worker terminal 93 is also configured to remotely control the concrete leveling vibrator 1. Commands from the worker terminal 93 take precedence over commands from the control device 91 during automated construction. This is to allow for response in emergencies.

[0063] The worker inputs the necessary work information into the control device 91 in advance using the worker terminal 93. This information includes travel speed, travel time, travel stop time, vibrator descent speed, vibrator insertion depth into the concrete, insertion time into the concrete, and withdrawal speed from the concrete.

[0064] Furthermore, although the work database 92 is shown as being constructed as external memory, the control device 91 may also be configured to acquire work information from the work database 92 located on the cloud via Wi-Fi (not shown) in the field environment.

[0065] The control device 91 and the work database 92 are equipped with artificial intelligence (AI), and the operator of the control device 91 may configure the system to automate the setting of various parameters by storing the parameters to be set (temperature, humidity, concrete material, etc.) in the work database along with the date and time, site name, and construction personnel at the site, thereby strongly promoting the AI-ization of concrete floor construction data.

[0066] Even in an unmanned, automated construction system, the functions described in the operation explanation for the concrete leveling vibrator 1 can be performed.

[0067] This allows even inexperienced workers to utilize parameters set by skilled craftsmen to perform concrete floor surface construction using rod-shaped vibrators with high precision and quality across almost the entire automated process.

[0068] In the above embodiment, the running wheels 5 were tires, but any configuration that can transmit rotational force to a concrete surface is acceptable, such as caterpillar tracks.

[0069] In the above embodiment, the concrete leveling vibrator 1,1A was used to level concrete, but it can also be applied to leveling mortar and other materials.

[0070] The above embodiment shows an example of concrete floor construction, but is not limited to this. Furthermore, the concrete leveling vibrator 1 can be used in any process that involves compaction using a rod-shaped vibrator.

[0071] Although each embodiment has been described in detail above, the invention is not limited to any particular embodiment, and various modifications and changes are possible within the scope described in the claims.

[0072] Furthermore, the present invention may include at least the following embodiments. These embodiments may be adopted separately or in combination with each other. (1) A concrete leveling vibrator having a sub-arm attached to the tip of the main arm and extending in a different direction from the main arm, and to which the vibrator can be attached to the tip of the main arm and the sub-arm, respectively.

(3) The sub-arms are provided in pairs on the left and right sides from the tip side of the main arm, and the tip sides of the pair of sub-arms are a concrete leveling vibrator that can move in the front-rear direction relative to the vibrator body by a sub-arm front-rear movement mechanism. (4) The vibrator is a concrete leveling vibrator whose mounting position of the sub-arm can be changed. (5) The vibrator is a concrete leveling vibrator that can be attached to the tip of the main arm. The vibrator is a detachable vibration device for leveling concrete. (6) The tip end of the main arm is a concrete leveling vibrator that is detachably configured and replaceable with a different type of part.
