An Interspersed Wind Barrier Structure Adapting to the Displacement of Expansion Joints

Abstract

The invention provides an alternate type wind barrier structure suitable for displacement of an expansion joint. The alternate type wind barrier structure comprises wind barrier stand columns and wind barrier strips. The wind barrier strips comprise alternate type barrier strip bodies. One end of each alternate type barrier strip body is the fixing end fixedly connected with the corresponding wind barrier stand column. The other end of each alternate type barrier strip body is a free end penetrating a hole formed in a web of the corresponding wind barrier stand column. Each free end and the adjacent corresponding wind barrier strip form an overlapped segment in the front-rear position. The alternate type wind barrier structure further comprises rolling wheels and fixing devices. The rolling wheels are fixed to the webs of the corresponding wind barrier stand columns through the fixing devices. The alternate type barrier strip bodies are in contact with the corresponding rolling wheels near the corresponding holes for reducing the friction resistance of the stand column webs and keeping the contact stability. When the alternate type wind barrier structure is used, the wind barrier strips are inserted into the stand column webs through the stand column holes in a penetrating manner and do reciprocating motion relative to the corresponding stand columns along displacement of the expansion joint, the purpose that the wind barrier strips are always in the area among the stand columns is achieved, and the wind barrier has good adaptability on the expansion joint.

Description

technical field [0001] The invention belongs to the field of bridge engineering and relates to an interspersed wind barrier structure adapted to the displacement of expansion joints. Background technique [0002] At present, among the bridges using wind barrier structure at home and abroad, the wind barrier structure is mostly set on the main bridge or the approach bridge. The displacement requirements cannot be met, so no wind barrier structure is set on the beam section of the expansion joint. Considering that the beam section of the expansion joint also needs to keep out the wind during the driving process of the bridge, it is objectively necessary to propose an interspersed bridge wind barrier that adapts to the displacement of the expansion joint and replace the traditional wind barrier with fixed barrier strips to meet the requirements of the bridge. Requirements for telescopic deformation. Contents of the invention [0003] The purpose of the present invention is ...
