Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Referring to fig. 1 and 2, the town road deceleration strip comprises a deceleration strip body 1 and a reflector 3 fixed on the surface of the deceleration strip body 1, wherein a first through hole 114 is formed in the deceleration strip body 1, and a fixing assembly 2 penetrates through the first through hole 114.

Referring to fig. 1 and 2, the speed bump body 1 includes a rubber sleeve 11 and a fixing frame 12. One side of the rubber sleeve 11 is a plane, the other side of the rubber sleeve 11 is an arc surface, and the fixing frame 12 is located inside the rubber sleeve 11. Two draw-in grooves 111 have been seted up to the one end of rubber sleeve 11, and rubber sleeve 11's the other end an organic whole is equipped with two fixture blocks 112, and the fixture block 112 is corresponding and can cooperate the card to be solid with draw-in groove 111's position for a plurality of deceleration strip bodies 1 can splice on a straight line.

Referring to fig. 2 and 3, since the rubber sleeve 11 is exposed to the sun and rain and is easily broken and damaged by rolling in the using process, in order to reduce the maintenance cost of the speed bump body 1, an inner cavity 115 with two open ends is arranged inside the rubber sleeve 11, and the profile section of the fixing frame 12 is matched and inserted with the inner cavity 115, so that the fixing frame 12 can be taken out of the rubber sleeve 11. The fixing frame 12 comprises a flat plate 121 and a convex plate 122 fixedly connected with the flat plate 121, wherein the convex plate 122 is arc-shaped, and the convex plate 122 and the flat plate 121 can be welded and fixed. In order to increase the load-bearing capacity of the fixed frame 12, a plurality of reinforcing ribs 123 are fixed between the convex plate 122 and the flat plate 121, and the fixed frame 12 may be made of high-strength metal such as alloy steel. One end of fixed frame 12 is fixed with backup pad 13, and backup pad 13 is with the tip shutoff of fixed frame 12, and when inserting fixed frame 12 in rubber sleeve 11, backup pad 13 and fixture block 112 butt prevent that the concatenation in-process fixture block 112 is pressed and is absorbed in the cavity of fixed frame 12. The support plate 13 also improves the strength of the fixing frame 12.

Referring to fig. 3 and 4, in order to reduce the possibility that the rubber sleeve 11 and the fixing frame 12 may slip off relatively during use, four first through holes 114 are formed at four corners of the rubber sleeve 11, and second through holes 1211 are formed at positions corresponding to the four corners of the flat plate 121. The fixing member 2 includes a bolt 21 and a sleeve 22 threadedly coupled to the bolt 21, the bolt 21 passing through the first through-hole 114 and the second through-hole 1211 in this order. The first through hole 114 and the second through hole 1211 may be screw holes, as required. A flange 221 is fixed to the outer wall of the sleeve 22. When the speed bump is used, the sleeve 22 can be embedded in the road surface 4, and the flange 221 can prevent the sleeve 22 from being pulled out under the action of external force, so that the speed bump body 1 is tightly fixed on the road surface 4.

Referring to fig. 3 and 5, in order to make it easy to find the speed bump for deceleration as soon as possible during night driving, a plurality of grooves 113 are formed on the surface of the rubber sleeve 11, and a plurality of reflective sheets 3 are respectively located in the grooves 113. Because the reflector 3 is arranged lower than the surface of the rubber sleeve 11, the abrasion of the reflector 3 is reduced to prolong the service life.

The application method of the municipal road deceleration strip comprises the following steps:

referring to fig. 4 and 5, a tool is used to drill a hole in the roadway 4 to place the sleeve 22, and then mortar is poured into the gap between the sleeve 22 and the hole to fix the sleeve 22. Then, after the speed bump body 1 is laid so that the first through hole 114 is aligned with the sleeve 22, the bolt 21 is screwed to the sleeve 22 through the first through hole 114, so that the speed bump body 1 is fixed on the road surface 4. And the deceleration strip bodies 1 are spliced by repeating the process.

If one of them deceleration strip body 1 takes place the damage after using a period, because of the existence of fixed frame 12, the whole height of deceleration strip can not too reduce, and the deceleration strip still has certain speed reduction effect. When these deceleration strips need to be changed, only need to unscrew bolt 21 from first through-hole 114, take off the deceleration strip body 1 of damage and change new deceleration strip body 1, the operation only needs unscrew or screw up bolt 21, and it is convenient to maintain, has avoided the deceleration strip to need to maintain and must smash road surface 4 earlier when changing and just can change, has practiced thrift time cost and economic cost. The removed damaged speed bump body 1 can be reused after the fixing frame 12 is pulled out of the rubber sleeve 11.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
