Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, and in particular to a sound insulation board for construction site enclosures. Background Technology

[0002] During construction, the operation of various construction machinery generates high-intensity noise, which can significantly disturb environmentally sensitive areas such as surrounding urban residential areas, schools, and hospitals. As a result, construction site fences with sound insulation and noise reduction functions have become standard equipment in construction projects. They effectively reduce the spread and impact of construction noise, and build a necessary protective barrier between engineering construction and environmental management.

[0003] For example, a Chinese patent published on January 17, 2023, entitled "A Road Construction Noise Barrier Enclosure" (Publication No. CN218324302U), discloses a base with an installation groove at its upper end. The installation groove contains a barrier assembly, which includes two steel plates and a central sound insulation layer. The sound insulation layer is fixedly connected to the two steel plates on both sides. A limiting mechanism for positioning the barrier assembly is provided within the installation groove. A connecting strip is fixedly connected to the left side of the left-side steel plate. An atomizing spraying mechanism is located at the upper end of the connecting strip, and a rotating mechanism cooperating with the atomizing spraying mechanism is located at the lower end of the connecting strip. This barrier, through the use of two steel plates and a sound insulation layer, ensures sound insulation performance. Furthermore, by using an electric motor to drive the spray nozzles in a rotating manner, it achieves dust removal over a wider area.

[0004] While the aforementioned technology ensures sound insulation of the enclosure through the use of two steel plates and a sound insulation layer, its lack of a leveling structure means that the fixed base is still difficult to adapt to uneven terrain on the construction site. Furthermore, the absence of a leveling structure necessitates significant manpower and resources for manual leveling during installation, resulting in low construction efficiency. Utility Model Content

[0005] The main purpose of this utility model is to provide a construction site enclosure sound insulation board, which solves the problem that the lack of a leveling structure in the existing technology makes it difficult for the construction site enclosure sound insulation board to adapt to complex terrain, and improves the practicality of the equipment.

[0006] The technical solution of this utility model is as follows:

[0007] A construction site enclosure sound insulation board includes a base, characterized in that the bottom of the base is provided with a leveling structure, the leveling structure including a leveling bolt, a leveling nut, and a support plate;

[0008] The base has several leveling bolts, leveling nuts, and support plates. The bottom of the base has several threaded through holes for cooperating with the leveling bolts. Each leveling bolt is threadedly connected to the threaded through holes. Each support plate is located on the side of the leveling bolt away from the base. Each leveling nut is threadedly connected to the leveling bolt. Each leveling nut is located between the support plate and the bottom of the base.

[0009] In one possible implementation, the base has a sealing skirt on the side facing the support plate. The sealing skirt is located on the edge of the base facing the support plate, and the sealing skirt covers the leveling structure and abuts against the ground.

[0010] In one possible implementation, the leveling bolt is further provided with a self-locking nut for self-locking, and the leveling nut and the self-locking nut abut against each other in the axial direction of the leveling bolt.

[0011] In one possible implementation, the support plate has a circular cross-section.

[0012] In one possible implementation, a load-bearing shim is provided on the end of the leveling bolt facing the support plate, and the load-bearing shim is fixedly connected to the support plate and the leveling bolt.

[0013] In one possible implementation, the support plate has a shock-absorbing pad on the side facing the ground, the shock-absorbing pad has anti-slip texture on the side facing the ground, and the shock-absorbing pad has the same area as the bottom surface of the support plate.

[0014] In one possible implementation, the sealing skirt is detachably connected to the base.

[0015] In one possible implementation, the base has an internal cavity filled with sound-absorbing material.

[0016] In one possible implementation, each of the leveling bolts, leveling nuts, and self-locking nuts is provided with a rust-proof lubricating layer.

[0017] The working principle and beneficial effects of this utility model are as follows:

[0018] In this embodiment, during installation, the sealing skirt is lifted, and the leveling bolts and leveling nuts of the leveling structure at the bottom of the base are used to adjust the length of the leveling bolts to adapt to different terrains. After adjusting to the appropriate level height, the self-locking nuts are tightened to prevent loosening, and the leveling is completed.

[0019] This embodiment features a leveling structure at the bottom of the base, allowing for flexible adjustment to uneven ground and adapting to various complex terrains. A self-locking nut ensures long-term stability. A double sound barrier is constructed using a sealed skirt combined with sound-absorbing material in the base cavity, effectively blocking noise transmission. Furthermore, the use of support plates, load-bearing pads, and vibration-damping pads evenly distributes the load and reduces vibration, enhancing the equipment's practicality.

[0029] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0030] like Figures 1-5 As shown, this embodiment proposes a construction site enclosure sound insulation board, including a base 1. The bottom of the base 1 is provided with a leveling structure 2, which includes a leveling bolt 21, a leveling nut 211, and a support plate 22. By using the leveling structure 2 at the bottom of the base 1, an adjustable support base is provided for this embodiment, enabling the base 1 to adapt to ground with different flatness, thus solving the problem of installation tilt or instability caused by uneven ground in traditional enclosures.

[0031] like Figure 3 As shown, the leveling structure 2 has several points of support, which distribute the load and prevent deformation of the leveling bolts 21 due to excessive force at a single point. At the same time, multi-point adjustment can more accurately correct the levelness of the base 1 and improve the overall stability. The bottom of the base 1 has several threaded through holes 11 for cooperating with the leveling bolts 21, and each leveling bolt 21 is threadedly connected to the threaded through hole 11. Utilizing the principle of thread transmission, the leveling bolts 21 can be raised and lowered within the threaded through holes 11. By rotating the leveling bolts 21, the height of the support plate 22 can be finely adjusted to adapt to various complex ground surfaces.

[0032] Each support plate 22 is located on the side of the leveling bolt 21 away from the base 1, and the support plate 22 is in direct contact with the ground, providing a stable support base for the leveling structure 2 and increasing the stability of the structure. Each leveling nut 211 is threadedly connected to the leveling bolt 21, and each leveling nut 211 is located between the support plate 22 and the bottom of the base 1. After the leveling nut 211 is tightened, it abuts against the bottom of the base 1, which can lock the height position of the leveling bolt 21, prevent the bolt from loosening due to vibration during use, and ensure the long-term reliability of the leveling state.

[0033] In this embodiment, a sealing skirt 3 is provided on the side of the base 1 facing the support plate 22. The sealing skirt 3 can effectively block external environmental factors (such as rainwater, dust, debris, etc.) from entering the contact area between the bottom of the base 1 and the leveling structure 2, protecting the leveling structure 2 from corrosion, reducing the risk of adjustment failure or structural damage caused by component corrosion, and extending the service life of the leveling structure 2. The sealing skirt 3 is located on the edge of the base 1 facing the support plate 22. Placing the sealing skirt 3 on the edge of the base 1 can maximize the coverage of the gap area between the base 1 and the ground. The length of the sealing skirt 3 is the same as that of the leveling structure 2 in its unadjusted state and abuts against the ground. When adjusting the leveling structure 2, the user only needs to lift the sealing skirt 3 to adjust the leveling structure 2. While protecting the leveling structure 2, the sealing skirt 3 can also prevent noise from propagating from the gap between the base 1 and the leveling structure 2, reducing noise leakage, and improving the overall noise reduction performance in conjunction with the sound insulation panel.

[0034] In this embodiment, the leveling bolt 21 is also equipped with a self-locking nut 212 for self-locking. The leveling nut 211 and the self-locking nut 212 constitute a double-nut self-locking structure, which improves the resistance to vibration and loosening through a double locking mechanism. The leveling nut 211 and the self-locking nut 212 abut against each other on the leveling bolt 21. After leveling to a suitable level, first tighten the leveling nut 211, and then tighten the self-locking nut 212. The two nuts generate opposite forces in the axial direction of the leveling bolt 21. After the self-locking nut 212 abuts against the leveling nut 211, static friction is generated on the contact surface. At the same time, friction is also formed with the contact surface of the leveling bolt 21. When subjected to vibration, the two nuts restrain each other, and the friction of the two thread pairs must be overcome simultaneously to loosen. This structure effectively prevents the threads from loosening due to construction or natural causes.

[0035] In this embodiment, the cross-section of the support plate 22 is circular. The advantages of a circular cross-section are: the circular cross-section makes the stress distribution of the support plate 22 more uniform in all directions. Compared with square or irregular shapes, a circle does not have stress concentration at the corners, which can effectively avoid deformation or damage to the support plate 22 caused by excessive local stress, thus enhancing the structural strength and durability of the support plate 22; at the same time, the symmetrical structure of the circular cross-section makes the contact area of ​​the support plate 22 on the ground evenly distributed, forming a more stable support state, which helps the fence maintain balance in complex environments and effectively reduces the possibility of the fence shaking or tipping over due to the tilting of the support plate 22.

[0036] In this embodiment, a load-bearing shim 23 is provided at the end of the leveling bolt 21 facing the support plate 22, which effectively expands the contact area between the end of the leveling bolt 21 and the support plate 22. This design can evenly distribute the concentrated load transmitted by the leveling bolt 21 onto the support plate 22, avoiding dents, deformations, or even damage to the support plate 22 due to excessive local pressure, and significantly improving the load-bearing capacity and service life of the support plate 22. The load-bearing shim 23 is fixedly connected to the support plate 22 and the leveling bolt 21, so that the three work together to bear the force. The axial force of the leveling bolt 21 can be transmitted to the support plate 22 more efficiently through the load-bearing shim 23, and then distributed to the ground, improving the mechanical performance and stability of the entire leveling structure 2.

[0037] like Figure 5As shown, in this embodiment, the support plate 22 has a shock-absorbing pad 24 with an area equal to the bottom surface area of ​​the support plate 22 on the side facing the ground. The shock-absorbing pad 24 completely covers the bottom surface of the support plate 22, ensuring that the force between the support plate 22 and the ground is evenly distributed. The shock-absorbing pad 24 buffers vibration through its own elastic deformation, effectively absorbing the vibration energy transmitted to the fence from the outside, avoiding the sound insulation board from loosening or the sound insulation performance from decreasing due to resonance, and extending the overall service life of the fence. The shock-absorbing pad 24 has anti-slip texture 241 on the side facing the ground. The anti-slip texture 241 increases the friction between the shock-absorbing pad 24 and the ground, preventing the fence from sliding and shifting under the action of external forces such as wind and ground shaking.

[0038] In this embodiment, the sealing skirt 3 is detachably connected to the base 1. This detachable connection greatly improves the maintenance convenience of the sound insulation panel. When the sealing skirt 3 becomes worn, aged, or damaged, it can be quickly disassembled and replaced with a new part without disassembling the entire enclosure structure, saving maintenance time and labor costs. In addition, when inspecting or repairing the leveling structure 2 on the bottom surface of the base 1, the detachable sealing skirt 3 provides convenient operating space, facilitating the inspection, lubrication, or replacement of components such as the leveling bolts 21 and leveling nuts 211, ensuring that the leveling structure 2 maintains a good working condition for a long time.

[0039] In this embodiment, the base 1 has a cavity 12 inside. The cavity 12 is a hollow space, which causes sound waves to be reflected and refracted when they encounter the boundary of the cavity 12 during propagation. This prolongs the sound wave propagation path, consumes some sound energy, and reduces the possibility of noise penetrating the base 1, thereby enhancing the overall sound insulation effect of the enclosure. At the same time, the hollow cavity 12 also reduces the weight of the base itself, making it easier to transport and install the enclosure, and reducing labor and machinery costs during construction. The cavity 12 is filled with sound-absorbing material, which further enhances the noise reduction function of the base 1 and significantly improves the noise reduction capability of this embodiment.

[0040] In this embodiment, the sound-absorbing material can be glass wool. Its advantages are that glass wool has excellent mid-to-high frequency sound absorption performance, is lightweight and non-flammable. It can not only further enhance the noise reduction function of the base 1 by fully absorbing sound waves, but also maintain the lightweight advantage of the cavity 12, reduce transportation and installation costs, and at the same time have good weather resistance and construction convenience.

[0041] In this embodiment, each leveling bolt 21, leveling nut 211, and self-locking nut 212 is provided with an anti-rust lubrication layer 25, which can prevent the components from rusting and the threads from getting stuck, thus extending the service life of the leveling structure 2. It can also reduce the coefficient of friction of the threads, making the adjustment operation smoother and improving the efficiency of installation and maintenance. At the same time, it can enhance the components' tolerance to complex environments such as high temperature and high humidity, ensuring the long-term stability and reliability of the leveling structure 2.
