Description

Technical Field

[0001] The utility model belongs to the field of road surface equipment and relates to a temporary pavement, in particular to a silent paving board. Background Art

[0002] During the construction process, steel plates are usually laid on the road surface as paving slabs to facilitate the passage of vehicles because the road surface has been dug up, or the repaired road surface has not yet been completely solidified, or in order to temporarily protect underground pipelines from being damaged by heavy-loaded engineering vehicles. However, when vehicles run over these steel plates, a "clang clang" sound is made, which seriously affects the lives of residents. The solution to this type of noise is to put some sacks under the steel plates to reduce the noise. After a few days of putting sacks under the steel plates, the impact and friction of the vehicles on the paving steel plates will cause the steel plates to move, so that the sacks are no longer under the steel plates or the sacks are crushed, and the noise reduction effect is lost, and the noise that disturbs the residents appears again.

[0003] In order to solve the noise problem of steel paving slabs, some manufacturers have developed polyethylene paving slabs. The noise generated by polyethylene when hit is much smaller than that of steel paving slabs. However, the use scenarios of this polyethylene paving slab are not as many as those of steel paving slabs. For example, if the road surface is dug up to form a pit, then polyethylene paving slabs cannot be used as temporary roads for vehicles to pass. Because polyethylene paving slabs are relatively soft, their rigidity cannot support the weight of the car and will cause dents, causing the vehicle to fall into the pit.

[0004] Chinese patent document "CN218932760U" discloses a road steel plate, which is pressed on the edge of the steel plate by a rubber ring, but the strength of the rubber ring is not enough, and the edge of the steel plate is still easy to lift up. Utility Model Content

[0026] Next, the technical solution of the present utility model will be clearly and completely described in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0027] As Figure 1 shown in the silent paving plate, it includes a paving plate assembly 1 and a vibration damping fastener 2. The paving plate assembly 1 has a general size of 2 meters * 6 meters and a thickness of 30 mm - 40 mm, and can be temporarily laid on the road surface in one or more pieces. The vibration damping fastener 2 is buckled on the edge of the paving plate assembly 1 to play a stabilizing role.

[0028] As Figure 2 , the paving plate assembly 1 includes a steel plate 11 and a vibration isolation plate I 12. The vibration isolation plate I 12 is arranged on the lower surface of the steel plate 11 (it can also be arranged on both the upper and lower surfaces of the steel plate 11).

[0029] The material used for the vibration isolation plate I 12 is an elastic polymer material, such as rubber, polyurea elastomer, polyurethane elastomer, etc.

[0030] The connection method between the steel plate 11 and the vibration isolation plate I 12 can be to connect with the steel plate 11 through the viscosity of the elastic polymer material itself. For example, apply polyurea elastomer coating to the steel plate 11 and it will be bonded to the steel plate after curing; the connection method between the steel plate 11 and the vibration isolation plate I 12 can also be to bond the two through an adhesive. For example, use an elastic structural adhesive to bond the rubber plate and the steel plate together; the connection method between the steel plate 11 and the vibration isolation plate I 12 can also be fixed through mechanical connection. For example, set a number of mounting holes on the steel plate 11 and the vibration isolation plate I 12, and fix the steel plate 11 and the vibration isolation plate I 12 together with bolts and nuts.

[0031] As Figure 3 and Figure 4 shown, the vibration damping fastener 2 of the present utility model includes a vibration damping buffer plate 21, a reinforcing plate 22, a vibration isolation plate II 23 and a fixed bolt 24.

[0032] The materials of the shock-absorbing buffer plate 21 and the vibration isolation plate II 23 are high molecular elastomers, and they are adhered to the reinforcing plate 22 through an adhesive.

[0033] The lower surface of the reinforcing plate 22 has a groove I 221 for the peripheral edge of the steel plate 11 to be embedded. The strength of the reinforcing plate 22 is greater than that of the shock-absorbing buffer plate 21. In this example, the reinforcing plate 22 is made of a steel plate, similar to a Z shape. The stiffness of directly pressing the shock-absorbing buffer plate 21 against the steel plate 11 is insufficient, and after long-term use, the edge of the steel plate 11 is prone to warping, and the glue between the steel plate 11 and the vibration isolation plate I 12 is prone to coming off. Using the reinforcing plate 22 with greater strength to press the steel plate 11 can avoid the above problems.

[0034] The vibration isolation plate II 23 is arranged between the reinforcing plate 22 and the edge of the steel plate 11 to achieve a sound insulation effect. The vibration isolation plate II 23 can be only arranged between the reinforcing plate 22 and the steel plate 11, or can extend to the whole between the reinforcing plate 22 and the ground. In this example, the vibration isolation plate II 23 extends to the whole lower surface of the reinforcing plate 22. The vibration isolation plate II 23 can be integral, or can be split like Figure 4 that.

[0035] The shock-absorbing buffer plate 21 is provided with a groove II 212 for the reinforcing plate 22 to extend into. The groove II 212 is on the lower surface of the shock-absorbing buffer plate 21. The groove II 212 can also not be on the lower surface of the shock-absorbing buffer plate 21, for example, inside the shock-absorbing buffer plate 21. The upper surface of the part of the reinforcing plate 22 exposed from the groove II 212 is flush with the shock-absorbing buffer plate 21 to facilitate the vehicle to pass.

[0036] The surface of the shock-absorbing buffer plate 21 facing away from the steel plate 11 is provided with a slope 211. The slope 211 extends obliquely from the top surface in the thickness direction of the shock-absorbing buffer plate 21 to the bottom surface, which is conducive to the vehicle passing and conducive to reducing the sound when the vehicle passes.

[0037] The shock-absorbing buffer plate 21, the reinforcing plate 22 and the vibration isolation plate II 23 are provided with through holes for the fixing bolts 24. The through holes of the fixing bolts 24 on the shock-absorbing buffer plate 21 are designed as counterbores, and the bolt heads of the fixing bolts 24 are located in the counterbores 213, so that the fixing bolts 24 will not be run over when the vehicle passes over the shock-absorbing fastener 2. The fixing bolts 24 can be expansion bolts or high-strength concrete self-tapping anchor bolts. The minimum number of fixing bolts 24 on a single shock-absorbing fastener 2 is one. Of course, it is more stable when there are two or more.

[0038] There are multiple sets of shock-absorbing fasteners 2, which are buckled at multiple points on the edge of the paving plate assembly 1, or can be set as an integral structure surrounding the paving plate assembly 1 in a circle.

[0039] In order to facilitate the arrangement of the shock-absorbing fasteners 2 on the construction site, the weight of a single shock-absorbing fastener 2 is not greater than 10 kg (excluding the weight of the fixing bolts 24).

[0040] The installation process of the silent paving plate is as follows: First, place the paving plate assembly 1 at the installation position, and the vibration isolation plate I 12 of the paving plate assembly 1 contacts the ground. According to actual usage needs, place several vibration damping fasteners 2 around the paving plate assembly 1 and ensure that the vibration isolation plate II 23 of the vibration damping fastener 2 presses on the paving plate assembly 1. After determining the installation position of the vibration damping fastener 2, use tools to drill installation holes for the fixing bolts 24 on the ground. Use the fixing bolts 24 to fix the vibration damping fastener 2 to the ground.

[0041] The silent paving plate fixes the vibration damping fastener 2 by using the fixing bolts 24, and the vibration damping fastener 2 restricts the movement and vibration of the paving plate assembly 1. When a vehicle drives over the silent paving plate, the tire first presses on the vibration damping buffer plate 21. Compared with the vehicle directly pressing on and impacting the steel plate 11, the elastic material and slope design of the vibration damping buffer plate 21 generate much less noise. After the vehicle drives onto the paving plate assembly 1, the vibration isolation plate I 12 is in direct contact with the ground. Compared with the direct contact between the steel plate 11 and the cement ground, the noise generated is much less.

[0042] The contact areas between the vibration damping fastener 2 and the paving plate assembly 1 are all made of elastic polymer materials and are limited by the fixing bolts 24. When the vehicle presses on the silent paving plate, no obvious noise that affects the environment will be generated in the contact areas between the vibration damping fastener 2 and the paving plate assembly 1.

[0043] In summary, by using the silent paving plate involved in the present utility model, the problem of noise nuisance caused by paving steel plates, which has been complained about a lot in society at present, can be solved.

[0044] The above embodiments are only used to illustrate the technical concept and features of the present utility model, and their purpose is to enable those who are familiar with this technology to understand the content of the present utility model and implement it accordingly. It cannot be used to limit the protection scope of the present utility model. All equivalent changes or modifications made according to the spirit and essence of the present utility model should be covered within the protection scope of the present utility model.
