Description

Technical Field

[0001] The utility model relates to the technical field of vibration construction, in particular to a vibration positioning assembly for a thin-walled cavity multi-curved fair-faced concrete arch Background Technique

[0002] In the modern construction field, fair-faced concrete has become the goal pursued by many designers with its unique texture and structural aesthetics. Among them, the thin-walled cavity multi-curved fair-faced concrete arch is a building component that combines complex geometric shapes and fine craftsmanship. It not only requires the strength and stability of the structure, but also emphasizes the beauty of the appearance and the smoothness of the lines

[0003] The overall height of the thin-walled cavity multi-curved fair-faced concrete generally exceeds 4m, and the outer facade is a curved surface. Before pouring, two or more layers of steel mesh parallel to the inner and outer pouring forms need to be tied and laid between the inner and outer pouring forms. The spacing between adjacent steel meshes is generally about 10cm. During pouring, it is carried out in layers, and the single pouring height is about 50cm. When vibrating and constructing such special-structured concrete components, construction workers need to stand on the top of the concrete arch and use a vibrating rod to extend between the two layers of curved steel meshes and insert it into the poured concrete layer. However, due to the obstruction of the vibrating rod by the curved steel mesh to the line of sight of the vibrating construction workers, the construction workers cannot visually observe the depth of the vibrating rod inserted into the concrete layer, thus affecting the progress of the vibrating construction and the final forming quality

[0004] Therefore, this application specifically proposes a vibration positioning assembly for a thin-walled cavity multi-curved fair-faced concrete arch to solve the above technical problems Content of the Utility Model

[0005] The main purpose of the utility model is to solve the above deficiencies, and provide a vibration positioning assembly for a thin-walled cavity multi-curved fair-faced concrete arch, which can position the height of the vibrating rod relative to the ground and help the vibrating construction workers know the real-time height of the vibrating rod during the insertion process when the line of sight is blocked

[0006] In order to solve the above technical problems, the utility model adopts the following technical scheme

[0007] A vibration positioning assembly for a thin-walled cavity multi-curved fair-faced concrete arch, comprising: a positioning label fixedly arranged inside the end of the vibrating rod; a vibration power generation assembly fixedly arranged inside the end and electrically connected to the positioning label, for generating electricity by using the vibration of the vibrating rod and supplying power to the positioning label; a positioning base station horizontally adjustable and arranged on the ground where the thin-walled cavity multi-curved fair-faced concrete arch stands, for monitoring the height of the positioning label; a wearable display device worn on the wrist or arm of the vibrating construction worker and wirelessly communicatively connected to the positioning base station, for real-time displaying the relative height where the positioning label is located

[0008] Further, the vibration power generation component includes a barrel-shaped polymer piezoelectric film fixedly arranged at the bottom of the inner cavity of the end head and a sphere movably arranged inside the polymer piezoelectric film, and the polymer piezoelectric film is electrically connected to the positioning label.

[0009] Further, an installation block is fixedly arranged in the inner cavity of the end head, the bottom end of the installation block abuts against the top end of the polymer piezoelectric film, and the positioning label is fixedly arranged on the top of the installation block.

[0010] Further, a supporting plate is fixedly arranged at the bottom of the positioning base station, supporting feet are arranged through four corners of the supporting plate, and two nuts are threadedly connected to the supporting feet, and the two nuts are respectively located on the top surface and the bottom surface of the supporting plate and abut against the supporting plate.

[0011] Further, the positioning base station takes the top surface of the supporting plate as a reference measurement plane.

[0012] Further, the wearable display device includes a strap and a display screen fixedly arranged on the strap, and the display screen is wirelessly communicatively connected to the positioning base station.

[0013] The beneficial effects of the present utility model are embodied in:

[0014] 1. By arranging a positioning label at the end of the vibrating rod and arranging a positioning base station on the ground for monitoring the height where the positioning label is located, the positioning base station can monitor the height where the positioning label is located in real time. The height measured by the positioning base station is used to represent the height of the end of the vibrating rod relative to the ground, and a wearable display device is arranged to display this height value, so that the vibrating construction personnel can know the height where the end of the vibrating rod is located by observing the wearable display device, which is convenient for controlling the depth of insertion of the vibrating rod into the concrete slurry, and still ensures the normal progress of the vibrating construction even when the line of sight is blocked by the steel mesh.

[0015] 2. By arranging a vibration power generation component electrically connected to the positioning label at the end head, the vibration of the vibrating rod is used for power generation and power supply to the positioning label. In this way, the positioning label does not need to be powered by a battery, and it is not necessary to frequently remove the end head from the vibrating rod to replace the battery for the positioning label, which improves the use convenience.

Detailed implementation manners

[0026] Next, in combination with the embodiments of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0027] As Figure 1-8 shown, the present utility model provides a thin-walled cavity multi-curved fair-faced concrete arch vibrating and positioning assembly, including:

[0028] The positioning label 1 is fixedly arranged inside the end 3 of the vibrating rod 2;

[0029] The vibration power generation component 4 is fixedly arranged inside the end 3 and is electrically connected to the positioning label 1, and is used for generating electricity by using the vibration of the vibrating rod 2 and supplying power to the positioning label 1;

[0030] The positioning base station 5 is horizontally adjustable and is set on the ground where the thin-walled cavity multi-curved fair-faced concrete arch stands, and is used to monitor the height of the positioning tag 1.

[0031] The wearable display device 6 is worn on the wrist or arm of the vibrating construction worker and is wirelessly communicatively connected to the positioning base station 5, and is used to display the relative height where the positioning tag 1 is located in real time.

[0032] During use, the vibrating construction worker wears the wearable display device 6 on the wrist or arm at an easy-to-observe position, and then turns on and inserts the vibrating rod 2 to vibrate the poured concrete slurry. After the vibrating rod 2 is turned on, it generates vibration, which drives the vibration power generation component 4 to generate electricity. The electric energy generated by the vibration power generation component 4 is transmitted to the positioning tag 1, enabling it to be powered on and work normally. The positioning base station 5 monitors the height where the positioning tag 1 is located in real time and transmits its height information to the wearable display device 6. The height where the positioning tag 1 is located can represent the height where the end of the vibrating rod 2 is located. The vibrating construction worker judges the height where the end of the vibrating rod 2 is located at this time by observing the height value displayed on the wearable display device 6, so as to facilitate controlling the depth of the vibrating rod 2 inserted into the concrete slurry and ensure the normal progress of the vibrating construction.

[0033] It should be noted that the positioning principle between the positioning tag 1 and the positioning base station 5 can adopt the UWB positioning technology. This positioning technology has the advantages of high positioning accuracy, low power consumption, and low project cost, etc., and is suitable for the positioning requirements of this solution. And the positioning tag 1 and the positioning base station 5 equipped with this technology belong to relatively mature existing technologies, so it will not be elaborated here.

[0034] In an embodiment, the vibration power generation component 4 includes a barrel-shaped polymer piezoelectric film 41 fixedly arranged at the bottom of the inner cavity of the end 3 and a sphere 42 movably arranged inside the polymer piezoelectric film 41. The polymer piezoelectric film 41 is electrically connected to the positioning tag 1.

[0035] With such a design, when the vibrating rod 2 vibrates, it drives the sphere 42 inside the end 3 to hit the polymer piezoelectric film 41 at a high speed, causing the polymer piezoelectric film 41 to generate electric energy, providing a basis for the power supply of the positioning tag 1.

[0036] It is worth explaining that the polymer piezoelectric film 41 refers to a type of polymer film that can convert mechanical stress into charge or voltage. One of the most common and important polymer piezoelectric films is polyvinylidene fluoride (PVDF). Due to its flexibility, light weight, processability, and good piezoelectric properties, this type of material has a wide range of applications in fields such as sensors, actuators, energy harvesters, and acoustic devices. In this embodiment, the polymer piezoelectric film 41 is used for energy harvesting. The mechanical energy of the impact of the sphere 42 is used as the input, which is converted into electrical energy by the polymer piezoelectric film 41, and after a series of collection, rectification, storage, and voltage stabilization, it powers the positioning tag 1. This belongs to relatively mature existing technology, so the working principle, circuit connection, etc. will not be elaborated here.

[0037] In one embodiment, a mounting block 7 is fixedly arranged inside the end 3. The bottom end of the mounting block 7 abuts against the top end of the polymer piezoelectric film 41, and the positioning tag 1 is fixedly arranged on the top of the mounting block 7.

[0038] With this design, due to the blockage of the mounting block 7, the sphere 42 always moves within the polymer piezoelectric film 41, ensuring the normal power generation of the vibration power generation assembly 4. At the same time, the mounting block 7 provides a stable and convenient installation platform for the positioning tag 1.

[0039] In one embodiment, a supporting plate 8 is fixedly arranged at the bottom of the positioning base station 5. Support feet 9 are penetrated through the four corners of the supporting plate 8, and two nuts 10 are threadedly connected to the support feet 9. The two nuts 10 are respectively located on the top surface and the bottom surface of the supporting plate 8 and abut against the supporting plate 8.

[0040] With this design, by adjusting the positions of the two nuts 10 on each support foot 9, the inclination angle of the positioning base station 5 relative to the ground can be adjusted. If the bottom surface where the support feet 9 are located is not flat, the supporting plate 8 can be adjusted to be horizontal through the above adjustment method, providing a horizontal positioning plane for the positioning base station 5.

[0041] In one embodiment, the positioning base station 5 uses the top surface of the supporting plate 8 as the reference measurement plane.

[0042] With this design, the positioning base station 5 can more accurately measure the height of the positioning tag 1. However, the height measured at this time is the height of the positioning tag 1 relative to the top surface of the supporting plate 8. Therefore, in actual use, it is also necessary to measure the height of the top surface of the supporting plate 8 relative to the ground. The actual height of the end of the vibrating rod 2 relative to the ground is the sum of the height value displayed on the wearable display device 6 and the height of the supporting plate 8 relative to the ground.

[0043] In one embodiment, the wearable display device 6 includes a strap 61 and a display screen 62 fixedly arranged on the strap 61. The display screen 62 is wirelessly communicatively connected to the positioning base station 5.

[0044] With such a design, by setting the strap 61, the vibrating construction worker can wear the display screen 62 on the body without holding it by hand, which is convenient for the vibrating construction worker to perform the vibrating operation while observing the display screen 62.

[0045] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above-described exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present utility model.

[0046] It should be noted that if there are directional indications (such as up, down, left, right, front, back...) involved in the embodiments of the present utility model, the directional indications are only used to explain the relative positional relationship and movement conditions between components in a certain specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0047] In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of those of ordinary skill in the art to implement. When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.
