Description

[0002] When constructing a noise-reducing driveway drainage grate, an iron base needs to be installed on the sewer manhole. The drainage grate is then embedded and fixed to the iron base. The purpose of adding the iron base is to prevent the drainage grate from shaking and damaging the sewer manhole when vehicles run over it. The added iron base can solve this problem. However, another problem arises: when vehicles pass by, the drainage grate rubs against the iron base, producing a metallic clanging sound. Utility Model Content

[0031] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0032] like Figure 1-4 As shown, a roadway drainage grate with noise reduction function includes a prefabricated sewer 1 and a drainage grate 2, and also includes a buffer 3, which is arranged on a staggered platform in the prefabricated sewer 1, and its upper surface is in contact with the drainage grate 2.
[0033] The buffer 3 is a foamed fiber stamped block, and the interior of the foamed fiber stamped block has a loose structure.
[0034] Specifically, the staggered platform in the embodiment is also known as the iron base. The iron base is inserted during the pouring of concrete for the precast sewer 1 and forms a whole after solidification.
[0035] In the embodiment, a prefabricated mold is used with a stamping process to place the foamed filaments of a predetermined length into the mold for stamping, thereby forming a foamed filament stamping block, i.e., buffer 3.
[0036] Furthermore, the material properties of foam itself are high elasticity, and after stamping, the interior is a loose structure rather than a dense state, so it has a strong elastic potential energy.
[0037] In the above technology, the buffer 3 is a foamed wire stamped block, and the interior of the foamed wire stamped block has a loose structure, so it has a certain buffering capacity. When a vehicle passes over and crushes the drainage grate 2, it will apply pressure to deform the buffer 3, thereby applying a damping force to the drainage grate 2, effectively reducing the noise caused by the misalignment between the drainage grate 2 and the prefabricated sewer 1.
[0038] During actual construction, four fixing bolts 4 are passed through the holes opened on the drainage grate 2 and the buffer 3 in sequence, and are threaded to the nuts fixed in the prefabricated sewer 1 to achieve fixation.
[0039] As a first embodiment further provided by this utility model, combined with Figure 2 As shown, the buffer 3 is a symmetrically arranged rectangular column, which is located on the side through which the fixing bolt 4 passes.
[0040] As a further embodiment of this utility model, combined with Figure 2 As shown, buffer 3 is a rectangular frame structure.
[0041] As a further embodiment of this utility model, the upper surface of the buffer 3 is provided with a groove, which can be U-shaped, V-shaped, U-shaped, or isosceles rectangle. The groove of a predetermined shape increases the buffer space and further optimizes the buffer damping after being subjected to force.
[0042] As another embodiment further provided by this utility model, combined with Figure 4 It can be seen that the buffer groove is specifically composed of two symmetrically arranged V-shaped groove structures, and three protrusions are formed on the upper surface of the buffer member 3. The protrusions are divided into isosceles trapezoidal parts 31 and right-angled trapezoidal parts 32 symmetrically arranged about the center of the isosceles trapezoidal parts, with the hypotenuses of the two right-angled trapezoidal parts 32 facing the isosceles trapezoidal parts 31. Therefore, when a vehicle passes through, the drainage grate 2 is subjected to force, causing the buffer member 3 to be subjected to a downward force. As the downward force increases, the right-angled trapezoidal parts 32 will move outward, thus receiving force from the foamed mesh of the main body below, thereby further optimizing the buffer damping after being subjected to force.
[0043] As another embodiment further provided by this utility model, combined with Figure 4 It can be seen that the lower surface of the buffer 3 is fixedly provided with an extension leg 33, and an isosceles trapezoidal groove 34 is formed between the two extension legs 33.
[0044] Furthermore, the sidewalls on opposite sides of the two extended legs 33 are inclined planes, and these inclined planes are parallel to the waist of the isosceles trapezoidal groove 34.
[0045] Specifically, in the embodiment, the two extended legs 33 are inclined toward the adjacent side, so an inverted isosceles trapezoidal groove 34 is formed between the two and the lower surface of the buffer 3. The lower surface of the buffer 3 is the lower base of the isosceles trapezoidal groove 34, while the two extended legs 33 are the waist of the isosceles trapezoidal groove 34, and the upper base is an open structure design.
[0046] When the drain grate 2 is subjected to force, the buffer 3 is subjected to a downward force. As the downward force increases, the two extended legs 33 will move toward the adjacent side, thereby receiving the foam mesh of the main body below, thus dividing the force and further optimizing the buffer damping after being subjected to force.
[0047] As another embodiment further provided by this utility model, combined with Figure 4 As can be seen, the above embodiments also include:
[0048] Rubber buffer 6 located within the isosceles trapezoidal groove 34;
[0049] Internal threaded screw 51 and limiting part 52;
[0050] Among them, the internal screw 51 passes through the screw hole and the rubber buffer 6 opened on the isosceles trapezoidal part 31 in sequence, and is threadedly connected to the limiting part 52.
[0051] The limiting part 52 is parallel to the bottom surface of the extension leg 33.
[0052] Furthermore, the rubber buffer 6 is divided into the following categories according to its function:
[0053] The arc-shaped portion 61 is connected to the inner wall of the extension leg 33;
[0054] An arched portion 62 that abuts against the side wall of the internal threaded screw 51.
[0055] Specifically, in this embodiment, a rubber buffer 6 is arranged inside the isosceles trapezoidal groove 34, and then installed by the cooperation of the internal threaded screw 51 and the limiting part 52. The limiting part 52 is a metal plate.
[0056] In practice, when the drainage grate 2 is subjected to force, the buffer member 3 experiences a downward force. As the downward force increases, the right-angled trapezoidal portion 32 moves outward. Simultaneously, the two extended legs 33 move towards their adjacent sides. At the same time, the rubber buffer member 6 is compressed vertically, causing the arc-shaped portion 61 to push the extended legs 33 outward with a force. The arched portion 62 then applies a force towards the side wall of the internal threaded screw 51.
[0057] Because the rubber buffer 6 in the embodiment is a PP rubber component, it will undergo axial contraction under the aforementioned force. The force applied by the arched portion 62 will squeeze the rubber buffer 6, thereby limiting its axial contraction and further optimizing the buffer damping after being subjected to force.
[0058] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
