[0001] The utility model relates to the technical field of municipal engineering, in particular to a noise-proof structure for paving steel plates. Background Art

[0002] With the development of urban development, noise pollution from construction sites is becoming increasingly serious. This is particularly true in densely populated areas, where the noise pollution generated by projects is disrupting the lives of surrounding residents. Furthermore, complaints and disputes are increasingly being raised about the noise caused by vehicles running over steel slabs laid on roads during construction. This noise not only affects residents' quality of life but can also lead to mental illness and disrupt student learning.

[0003] During municipal construction, noise pollution from paving steel slabs arises from uneven road surfaces and uneven steel slabs, which prevent the road surface from fully fitting the slabs, leaving gaps. When vehicles run over the slabs, they impact the road surface, generating noise. Furthermore, the number of slabs installed and the volume of traffic further increase noise pollution. Construction noise pollution can easily cause the following hazards:

[0004] 1. Impact on residents' health: Long-term exposure to noise may cause hearing damage, mental illness, decreased sleep quality and other problems.

[0005] 2. Impact on students' learning: Construction noise around the school will affect students' learning attention, memory, etc.

[0006] 3. Impact on the city’s image: Noise pollution will affect the overall environmental quality of the city and reduce the city’s image.

[0007] 4. Cause traffic accidents: Noise pollution affects drivers' attention and judgment, increasing the risk of traffic accidents. Utility Model Content

[0024] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific embodiments.

[0025] The first embodiment of the present invention provides a paving steel plate noise prevention structure, see Figure 1 It includes a plurality of steel plates 1 laid on a road surface 3 and distributed continuously. The road surface here can be a city trunk road in the municipal construction process, and the number of steel plates is laid according to the needs of the municipal engineering. The continuously distributed steel plate system has an inlet end and an outlet end. Figure 1 The left end is defined as the entrance end, Figure 1 The right end is defined as the exit end. A first guide block 2 is distributed at the entrance end of the steel plate system. The first guide block 2 guides the passing car onto the steel plate through a guiding slope to prevent the car from colliding with the steel plate and generating noise when in contact with the steel plate. A second guide block 4 is distributed at the exit end of the steel plate system to prevent the associated noise generated by the drop after the car exits the steel plate system. A front noise-proofing base 5 is installed between the first guide block and its adjacent steel plate, and a rear noise-proofing base 6 is provided between the second guide block and its adjacent steel plate. A steel plate system noise-proofing base 7 is provided between adjacent steel plates in the continuously distributed steel plate system. Here, the front noise-proofing base 5, the rear noise-proofing base 6, and the steel plate system noise-proofing base 7 can adopt the same structure. The parts of the front noise-proofing base 5, the rear noise-proofing base 6, and the steel plate system noise-proofing base 7 that contact the steel plate or the guide block are at least made of flexible material. This flexible material can significantly reduce the impact noise between structures.

[0026] See also Figure 2-4 The front noise-proof base support 5, the rear noise-proof base support 6, and the steel plate system noise-proof base support 7 have a bottom support plate 8 extending along the width direction of the steel plate and a partition plate 9 vertically installed on the bottom support plate. The bottom support plate 8 and the partition plate 9 are integrally formed and can be made of rubber material.

[0027] Of course, considering the integrity of the structure, the anti-slip structure is an adhesive provided between the front noise-proof base 5, the rear noise-proof base 6, the steel plate system noise-proof base 7 and their respective connectors. Figure 1 The surface of the partition plate of the front noise-proof bottom bracket 5 is coated with an adhesive to achieve the connection with the first guide block 2 and the steel plate ( Figure 1 The left side steel plate in the middle) is bonded and fixed, and the surface of the partition plate of the rear noise-proof bottom bracket 6 is coated with an adhesive to achieve the connection with the second guide block 4 and the steel plate ( Figure 1The right steel plate in the middle is bonded and fixed, and the surface of the partition plate of the steel plate system noise-proof base 7 is coated with adhesive to achieve bonding and fixing with the steel plates on both sides. Here, the adhesive structure is used to achieve an integral connection structure between the corresponding base and the respective connectors (here, the connector refers to the first guide block, the second guide block, and the steel plate).

[0028] The second embodiment of the present invention provides a noise-proof structure for paving steel plates, which differs from the first embodiment in that the anti-slip structure is a pulling structure between the front noise-proof base support 5, the rear noise-proof base support 6, the steel plate system noise-proof base support 7 and their respective connectors.

[0029] See also Figure 5 Here, the steel plate system noise-proof base support 7 is used as an example for explanation. The partitions of the steel plate system noise-proof base support 7 are symmetrically provided with horizontally distributed T-slots, and T-shaped protrusions 10 matching the T-slots are provided on the steel plate. The T-shaped protrusions here can be plastic blocks / metal blocks that are external to the steel plate and fixed with adhesives or screws. During installation, the T-shaped protrusions are placed into the T-slots of the steel plate system noise-proof base support 7. This can effectively enhance the integrity between the steel plate system noise-proof base support 7 and the steel plate. At the same time, inverted T-slots are also provided on the surface of the side ear plates of the steel plate system noise-proof base support 7, and T-shaped protrusions matching the inverted T-slots are provided on the bottom of the steel plate (which can be plastic blocks / metal blocks that are external to the steel plate and fixed with adhesives or screws). This can further enhance the structural integrity between the steel plate system noise-proof base support 7 and the steel plate, which has a positive promoting effect on noise reduction. Here, the T-shaped protrusions are made of plastic integral injection molding and then fixed to the steel plate by adhesive. The bottom bracket where the two guide blocks are located adopts the same structural design.

[0030] The third embodiment of the present invention provides a noise-proof structure for paving steel plates, which differs from the second embodiment in that a tongue is provided on the top of the noise-proof base of the steel plate system.

[0031] See also Figure 6 For the steel plate system noise-proof base support 7, the top of its partition is generally flush with the steel plate after installation. It is possible to consider setting a vertically extended tongue with a thickness less than the partition on the top of the steel plate system noise-proof base support 7 partition (to avoid the tongue being too thick to produce deflection and deformation). The height of the tongue 11 is about 3-5mm. This can prevent the partition from being squeezed after long-term use, resulting in insufficient height and collision with the edge of the steel plate, resulting in additional noise. At the same time, the tongue can be used to play a height compensation effect when the horizontal heights of the steel plates on both sides are not flush during early use. When the car is driving here, the tongue is deflected and deformed to reduce the possibility of the tire hitting downward due to the height difference of the steel plates.

[0032] The fourth embodiment of the present invention provides a noise-proof structure for paving steel plates, which differs from the first embodiment in that a pulling device is provided between noise-proof bottom supports of adjacent steel plate systems in the steel plate system.

[0033] exist Figure 7 In the system shown, the noise-proof bottom support of the steel plate system will have a gap with the ground after the bottom of the steel plate is lifted up by the bottom support. During long-term operation, the noise-proof bottom support of the steel plate system will have problems such as displacement. A pulling device is provided between the noise-proof bottom supports of adjacent steel plate systems in the steel plate system, so that the adjacent bottom supports can be pulled each other without displacement. The pulling device 12 here includes but is not limited to carbon fiber wires, and 3-5 carbon fiber wires can be provided along the width direction of the adjacent steel plate system noise-proof bottom supports for pulling, which not only meets the structural strength requirements, but also can reduce the lifting of the steel plate itself due to the appearance of the pulling device.

[0034] Those skilled in the art will appreciate that the above-mentioned embodiments are specific examples for implementing the present invention, and in actual applications, various changes may be made thereto in form and detail without departing from the spirit and scope of the present invention.
