Embodiment Construction

[0019] refer to figure 1 , 2 , 3, 4, 6, the present invention is made of one or more wind barrier units, and every two columns 2 and their upper and lower upper beams 3 and lower beams 5 form a wind barrier unit, and the columns 2 and their upper and lower upper beams 3 and The lower crossbeam 5 constitutes the barrier support of the diversion type wind barrier 1 . The axis of the column 2 is composed of multiple straight lines, arcs or broken lines along the height direction, so that there is an angle of 1°-45° between the axis of the column 2 and the plumb line. In order to strengthen the integrity of the wind barrier support, a middle beam 4 can be added between the upper beam 3 and the lower beam 5 .

[0020] The upper crossbeam 3 and the middle crossbeam 4 have two kinds of structural forms: integral and combined. When the upper crossbeam 3 and the middle crossbeam 4 are integrally constructed, the upper crossbeam has air passage holes 6, and the arrangement positions ...

Abstract

The invention relates to a flow guide type air barrier. An air barrier support is composed of upright columns, an upper beam and a lower beam, and forms an air barrier unit. The dip angle between the axis of each upright column of the air barrier and a plumb line ranges from 1 degrees to 45 degrees. Multiple rows of transverse air barrier bars and multiple columns of vertical air barrier bars are distributed in the air barrier support and are connected smoothly on the windward side to form a whole air barrier face. The vertical air barrier bars are arranged continuously at equal intervals between the upper beam and the lower beam, and dip angles ranging from 1 degree to 45 degrees are formed between the vertical air barrier bars and the plumb line. The upper beam and the lower beam of the air barrier can be integrated or combined. Flow guide air barrier bars are additionally arranged on the windward side of the whole air barrier face. By means of the air barrier, a part of air flow can bypass an air barrier plate, so that the flow guide type air barrier has a wind shielding function as a common air barrier and also has an air flow guide function. When the air barrier is applied to a noise barrier, wind resistance of the noise barrier can be improved. By means of the air barrier, the pneumatic characteristics o f a bridge structure can be improved, and wind resistance of the bridge structure is improved.

Description

technical field [0001] The invention relates to a diversion type wind barrier which can be used for road and railway bridges. Background technique [0002] Larger wind loads will pose a certain threat to the safety of vehicles on the road and trains on the railway line; today, with increasing environmental protection requirements, sound barriers have been widely used on roads and railway bridges. The wind resistance of the barrier itself has attracted great attention. Installing wind barriers and sound barriers on highway and railway bridges can improve the driving conditions on the bridge, but it has a certain impact on the aerodynamic characteristics of the bridge and the wind resistance of the structure, especially for long-span bridges, especially kilometers across the sea. For long-span bridges over a kilometer, these adverse effects will be more prominent. [0003] Engineering examples show that conventional sound barriers have sufficient wind resistance in areas wit...
