[0027] In a specific embodiment, the improved speed bump 100 comprises a lower hollow metal strip 1 extending along the width direction of the road surface, and an upper rubber strip 2 is embedded in the lower part of the metal strip 1, a plurality of countersunk holes 11 are arranged on the upper part of the metal strip 1, and a plurality of through holes corresponding to the countersunk holes 11 are arranged on the upper rubber strip 2. When the speed bump 100 is installed, the speed bump 100 is fixed to the road surface by screws passing through the countersunk holes 11 and the through holes.
[0028] The speed bump is improved scientifically and rationally, the upper part of the strip is a metal strip 1, and the lower part is a rubber strip 2, and the two parts are tightly combined into one. Compared with the common rubber speed bump, the speed bump provided by the utility model increases the impact resistance and wear resistance, reduces the occurrence of wear and damage of the upper strip after being impacted, and prolongs the service life. In addition, compared with the common hollow structure speed bump, the friction between the bottom and the road surface is increased, and the overall compression resistance of the product is improved, that is, the use safety and stability are increased. Therefore, the safety and stability of the speed bump are improved, and the service life of the speed bump is also prolonged.
[0029] In a specific embodiment, the metal strip 1 and the rubber strip 2 of the speed bump are tightly combined by hot pressing. That is, the upper metal strip 1 is combined with the lower hot-melt rubber strip 2 by nesting, and then is subjected to strong stamping, so that the upper metal strip 1 and the lower rubber strip 2 are tightly fixed and have no gap and looseness, and can form a tightly combined stable whole strip.
[0030] In a specific embodiment, the metal strip 1 of the speed bump is a stamping strip. Preferably, the metal strip 1 is a stamping steel plate strip. The stamping forming mode is easy to form various concave-convex shapes, and can obtain a smooth surface, thereby reducing subsequent processing.
[0031] As shown in Figure 2 Based on the above specific embodiment, a plurality of stamping connection sockets 12 are uniformly distributed on the metal strip 1, the stamping connection socket 12 is formed by the metal strip 1 body and the metal sheet 13 stamped on the lower part of the metal strip 1 body, and the part of the edge of the metal sheet 13 is connected with the metal strip 1 body. Through the stamping connection socket 12, the nesting combination strength of the metal strip 1 and the lower hot-melt rubber strip 2 can be improved, so that the connection between the metal strip 1 and the rubber strip 2 is more firm.
[0032] As shown in Figure 3As shown, based on the above-described specific embodiment, the left-right direction of the metal strip 1 aligns with the width of the road surface, and the front-to-back direction of the metal strip 1 aligns with the length of the road surface. The metal strip 1 includes a middle planar portion 14, a front ramp portion 15 integrally connected to the front side of the middle planar portion, and a rear ramp portion 16 integrally connected to the rear side of the middle planar portion. The front portion of the front ramp portion 15 is further bent downward to form a front vertical portion 17, and the rear portion of the rear ramp portion 16 is further bent downward to form a rear vertical portion 18. The front vertical portion 17, the front ramp portion 15, the middle planar portion 14, the rear ramp portion 16, and the rear vertical portion 18 are successively rounded. The front ramp portion 15 and the rear ramp portion 16 facilitate vehicle passage, the middle planar portion 14 allows for a smooth transition between the front ramp portion 15 and the rear ramp portion 16, and the front vertical portion 17 and the rear vertical portion 18 prevent vehicles from contacting the edges of the metal strip 1 and facilitate wrapping of the rubber-plastic strip 2.
[0033] like Figure 1 and Figure 2 As shown, based on the above-described specific embodiment, the punched connection tabs 12 are provided on the middle planar portion 14, and the countersunk holes 11 are provided on the front slope 15 and the rear slope 16. Specifically, each section of the metal strip 1 of the present invention is provided with six punched connection tabs 12 and four countersunk holes 11. The six punched connection tabs 12 are arranged in three rows in the left-right direction and two rows in the front-to-back direction on the middle planar portion 14. Two countersunk holes 11 are provided on each of the front slope 15 and the rear slope 16. The countersunk holes 11 on the two slopes of the metal strip 1 and the punched connection tabs 12 on the middle planar portion together restrain the rubber-plastic strip 2, ensuring a secure connection between the metal strip 1 and the rubber-plastic strip 2.
[0034] like Figure 2 As shown, based on the above-described specific embodiment, the downward projection of the metal sheet 13 is rectangular, with the sides of the metal sheet 13 being longer in the front-to-back direction, and the left-to-right edges of the metal sheet 13 being connected to the main body of the metal strip 1. Providing the longer sides of the metal sheet 13 in the longer direction of the metal strip 1 can increase the size of the stamped connection slot 12, thereby making the connection between the metal strip 1 and the rubber-plastic strip 2 more secure.
[0035] like Figure 1 and Figure 2 As shown, based on the above specific embodiment, the upper surface of the metal strip body 1 is formed with an anti-skid stripe groove 19. The anti-skid stripe groove 19 also forms a stripe protrusion toward the side of the rubber strip body 2, thereby increasing the tightness of the combination of the metal strip body 1 and the rubber-plastic strip body 2.
[0036] like Figure 4 As shown, in a specific embodiment, the bottom surface of the metal belt body 1 is flush with the bottom surface of the rubber-plastic belt body 2 so as to jointly bear the pressure, thereby improving the overall pressure resistance of the speed bump.
[0037] As Figure 4 shown, in a specific embodiment, the bottom surface of the rubber belt 2 is evenly distributed with a plurality of vertical holes 21. The vertical holes on the rubber belt 2 can reduce the use of rubber material, save cost, but do not particularly affect the vertical direction of the speed bump resistance.
[0038] The various embodiments in the specification are described in a progressive manner, and each embodiment focuses on the difference from other embodiments. The same or similar parts between the various embodiments can be referred to each other.
[0039] The improved road and bridge pavement vehicle speed bump provided by the present application is described in detail above.
