Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-4, the present invention provides a technical solution: a deceleration strip for municipal engineering comprises a deceleration strip rubber block 1 and a supporting beam 2, wherein two clamping grooves 5 are formed in the bottom end surface of the deceleration strip rubber block 1 in a vertically downward extending mode, the deceleration strip rubber block 1 is clamped with the supporting beam 2 through the clamping grooves 5, stress holes 8 are formed in the deceleration strip rubber block 1 on the outer side of each clamping groove 5, T-shaped limiting grooves 7 are formed in the deceleration strip rubber blocks 1 on two sides of each clamping groove 5, a second fixing hole 10 is formed in the deceleration strip rubber block 1 between the two clamping grooves 5, a threaded hole 3 is formed in the bottom end wall body of the supporting beam 2, a bolt 4 is screwed in the threaded hole 3, first fixing holes 9 are formed in two side wall bodies of the supporting beam 2, limiting blocks 6 matched with the limiting grooves 7 are formed in a horizontally outward extending mode in the two side wall bodies of the supporting beam 2, the limiting blocks 6 are embedded into the limiting grooves 7, studs 11 are inserted into the first fixing holes 9 and the second fixing holes 10, and the both ends threaded connection of double-screw bolt 11 has nut 12, present deceleration strip all is a long banding block rubber, when the vehicle went from the deceleration strip like this, the gravity of car can be exerted on the deceleration strip, the deceleration strip can change at car action of gravity self overall dimension down, and internal stress concentrates, the crackle appears easily like this, lead to the fragile, and the deceleration strip in this application is provided with stress hole 8, can disperse the inside stress of deceleration strip, avoid the deceleration strip to damage, long service life.

Deceleration strip block rubber 1 is equidistant distribution on a supporting

beam

2, and 1 whole length of deceleration strip block rubber is unanimous with a supporting beam 2 length, and deceleration strip block rubber 1 is provided with a plurality ofly, and after deceleration strip somewhere damages like this, only need to change the deceleration strip block rubber 1 of this department can, need not to change whole deceleration strip, so not only be convenient for maintain, and reduced the cost of maintaining, excellent in use effect.

The section of the supporting beam 2 is of a "" shape structure, the whole supporting beam 2 is made of metal, the supporting beam 2 can be made of alloy steel, the strength is high, and the supporting beam is not easy to deform in use.

The top surface of bolt 4 flushes with a supporting beam 2's surface, and a supporting beam 2 laminates with deceleration strip rubber block 1 mutually, when a fixed stay beam 2, with the internal bolt 4 that revolves of screw hole 3, and with bolt 4 screw in to ground in, a supporting beam 2 can be fixed firm with ground like this, later with 1 block of deceleration strip rubber block and a supporting beam 2, under stopper 6 and spacing groove 7's effect, not only be convenient for fix a position installation deceleration strip rubber block 1, and horizontal displacement can not take place for deceleration strip rubber block 1 after the installation, further improved the fastness between deceleration strip rubber block 1 and a supporting beam 2, deceleration strip rubber block 1 is inseparable with a supporting beam 2 laminating simultaneously, automobile gravity part that deceleration strip rubber block 1 received can transmit for a supporting beam 2, avoid deceleration strip rubber block 1 atress too big and damage.

Stress hole 8 and second fixed orifices 10 all are linked together with the cell wall of draw-in groove 5, and stress hole 8, second fixed orifices 10 and the coaxial line of first fixed orifices 9 three, when deceleration strip block rubber 1 through draw-in groove 5 with prop up 2 both sides wall body block closure of supporting beam, stress hole 8, second fixed orifices 10 and first fixed orifices 9 three align, can insert double-screw bolt 11 to second fixed orifices 10 and first fixed orifices 9 in from stress hole 8 like this, rational in infrastructure.

The inner diameters of the second fixing hole 10 and the first fixing hole 9 are consistent with the diameter of the stud 11, the inner diameters of the second fixing hole 10 and the first fixing hole 9 are smaller than the inner diameter of the stress hole 8, and the stress hole 8, the second fixing hole 10 and the first fixing hole 9 are designed in size, so that after the stud 11 is inserted into the second fixing hole 10 and the first fixing hole 9, the nut 12 can be screwed into two ends of the stud 11 in the stress hole 8.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
