Description
Technical Field
The utility model relates to a public road bridge roof beam technical field, in particular to highway sound insulation protective screen support post.
Background
In the middle of the 20 th century, vehicles were rapidly increasing at that time, and sound-proof barriers were invented, which were widely used when noise regulations passed; the sound insulation barrier is one of methods for relieving noise, is also the most effective method for relieving noise of roads, railways, industrial noise sources and the like, is mostly used for roads, and is also surrounded on the ground in buildings to reduce the disturbance of noise and dust to pedestrians or nearby places. The sound insulation protective screen is installed on crash barrier in the part, the sound insulation protective screen is fixed mounting between two sound insulation protective screen steel stand columns, and there is only a stand bottom plate current steel stand bottom, need pre-buried steel sheet in crash barrier concrete before the installation, be fixed on the stand bottom plate by pre-buried U type bolt free end during the installation, accomplish the installation work, the sound insulation protective screen is installed on the bridge mostly, and most all are the crosswind district on the bridge, it can make the sound insulation protective screen rock insecure to lead to this fixed mode, the maintenance work volume in later stage has been increased, and before the installation steel stand, need pre-buried steel sheet in crash barrier concrete, this work is wasted time and energy.
Disclosure of Invention
The utility model aims to provide a: the utility model provides a highway sound insulation protective screen support post, it is firm, installation labour saving and time saving to guarantee that it installs on anticollision barrier.
The utility model provides a highway sound insulation protective screen support post, includes the stand body, the stand body sets up on the bottom plate, the bottom plate sets up on anticollision barrier top, pre-buried U type bolt that has the opening up in the anticollision barrier, U type bolt and anticollision barrier parallel, and U type bolt both free ends run through the bottom plate respectively and have the nut to lock, the bottom plate rear side is equipped with the locating plate of hugging closely anticollision barrier trailing flank, be equipped with two positioning bolt on the coplanar perpendicularly on the anticollision barrier, two positioning bolt run through the locating plate and are locked by the nut.
Further, two positioning bolts penetrate through the U-shaped bolt.
Furthermore, the two opposite sides of the upright column on the bottom plate are respectively provided with a first reinforcing rib, and one first reinforcing rib is positioned between the two free ends of the U-shaped bolt.
Furthermore, a second reinforcing rib parallel to the first reinforcing rib is arranged on the positioning plate under the bottom plate.
Still further, the transverse section of the upright post body is H-shaped.
The beneficial effects of the utility model reside in that:
the utility model discloses a highway sound insulation protective screen support post, through hugging closely crashproof guardrail trailing flank locating plate that sets up at the bottom plate rear side, and U type bolt, make fixing on crashproof guardrail that the bottom plate can be fine, thereby make the stand obtain fine fixed, avoided the frequent maintenance work in later stage, through first strengthening rib and the second strengthening rib that sets up, make better obtaining of bottom plate and stand and bottom plate and locating plate fixed, better assurance the firm of stand.
