Description
Technical field
The utility model belongs to sound barrier technical field, specifically, relates to a kind of Liftable type highway noise barrier.
Background technology
Along with highway in China construction great development; exerting a certain influence of highway construction on environment; wherein the impact of the acoustic environment sensitizing range (school, residential block, nature protection area etc.) of Highways ' is highlighted day by day; current, the safeguard measure of sound barrier is installed in the many employings of highway administration department additional at curb.Such as, Chinese patent (CN202899051U) disclose a kind of there is " work " shape groove by multiple steel post frame and the assembled sound barrier of multiple sound absorption unit board.This measure is when often vehicle flowrate is less in early days, sound environment quality is up to standard, but along with highway is runed for a long time, vehicle flowrate increases year by year, acoustic environment there will be the phenomenon exceeded standard, but due to all integrated sound barrier of the sound barrier installed in early days, can only remove and reinstall the sound barrier increased and could solve the problem that noise exceeds standard, the problem of waste resource can be caused unavoidably.
Summary of the invention
For solving the problems of the technologies described above, the utility model provides the Liftable type highway noise barrier of a kind of efficient, economy, environmental protection.
A kind of Liftable type highway noise barrier described in the utility model, described sound barrier comprises H profile steel column 1, fixing sound barrier 2 and can promote sound barrier 3; Described H profile steel column 1 is located on bridge-collision-avoidance wall, the U-shaped steel buckle 5 that the useful double-threaded screw of its top cover 4 is fixing; Described fixing sound barrier 2 is fixed in the inboard groove of adjacent two H profile steel columns 1; The described sound barrier 3 that promotes is fixed on the top of the inboard groove of adjacent two H profile steel columns 1 and is sandwiched in fixing sound barrier 2 inside, and its top is not above fixing sound barrier 2; The described both sides promoting sound barrier 3 are provided with screw 6, can be connected by double-threaded screw 4 with the hole on H profile steel column 1; Described fixing sound barrier 2 and sound barrier 3 can be promoted make by color steel sound barrier.
A kind of Liftable type highway noise barrier described in the utility model, described H steel post 1 wide width wing edge H profile steel that is high by cross section and the wide 120mm of being of wing plate is made.
A kind of Liftable type highway noise barrier described in the utility model, described wide width wing edge H profile steel is processed into by deformed steel column Q235 Plate Welding, and weldering meets Gao Du≤6mm.
A kind of Liftable type highway noise barrier described in the utility model, the Q235 steel that described deformed steel column is 215MPa by stretch-proof design strength and resistance to compression design strength are made.
A kind of Liftable type highway noise barrier described in the utility model, the described outside average mark promoting sound barrier 3 is furnished with screw 6, and screw 6 internal diameter is consistent with double-threaded screw 4.
A kind of Liftable type highway noise barrier described in the utility model, described screw 6 outward flange promoting sound barrier 3 is consistent with the distance of H profile steel column 1 with the screw outward flange of fixing sound barrier 3.
A kind of Liftable type highway noise barrier described in the utility model, the described screw 6 promoting sound barrier 3 is between the upper and lower every being 100mm.
A kind of Liftable type highway noise barrier described in the utility model, the described sound barrier 3 that promotes is highly 1/2 of fixing sound barrier 2 height.
Compared with prior art, Liftable type highway noise barrier described in the utility model can be avoided because the traffic volume increases, the phenomenon that trackside acoustic environment sensitive spot noise exceeds standard; When noise exceeds standard, the utility model, without the need to changing, only needs the connection of the screw and double-threaded screw that can promote sound barrier to untie, fixes again, protection of acoustic environment target noise so both can have been made up to standard, again saved resource after being risen to certain altitude.
Accompanying drawing explanation
Fig. 1: Liftable type highway noise barrier schematic diagram; Fig. 2: sound barrier schematic diagram can be promoted; H profile steel column-1, fixing sound barrier-2, sound barrier-3, double-threaded screw-4, U-shaped steel buckle-5, screw-6 can be promoted.
Detailed description of the invention
Below in conjunction with specific embodiment, Liftable type highway noise barrier described in the utility model is described further, but protection domain of the present utility model is not limited to this.
Embodiment 1
A kind of Liftable type highway noise barrier described in the utility model, described sound barrier comprises H profile steel column 1, fixing sound barrier 2 and can promote sound barrier 3; Described H profile steel column 1 is located on bridge-collision-avoidance wall, the U-shaped steel buckle 5 that the useful double-threaded screw of its top cover 4 is fixing; Described fixing sound barrier 2 is fixed in the inboard groove of adjacent two H profile steel columns 1; The described sound barrier 3 that promotes is fixed on the top of the inboard groove of adjacent two H profile steel columns 1 and is sandwiched in fixing sound barrier 2 inside, and its top is not above fixing sound barrier 2; The described both sides promoting sound barrier 3 are provided with screw 6, can be connected by double-threaded screw 4 with the hole on H profile steel column 1; Described fixing sound barrier 2 and sound barrier 3 can be promoted make by color steel sound barrier.
