Title:
ASSEMBLED GUARDRAIL AND ASSEMBLING APPARATUS THEREFOR
Document Type and Number:
WIPO Patent Application WO/2023/168784
Kind Code:
A1
Abstract:
An assembled guardrail comprises at least one cross beam (1) which is transversely arranged and a plurality of longitudinal beams (2) which are arranged at intervals and are vertically arranged, a plurality of first connection holes being arranged at intervals on the wall of the cross beam (1) attached to the longitudinal beams (2), second connection holes corresponding to the first connection holes of the cross beam (1) being arranged on the walls of the longitudinal beams (2) attached to the cross beam (1), and connection devices passing through the first connection holes and the second connection holes. After a connection device connects a longitudinal beam (2) and the cross beam (1), the longitudinal beam (2) can rotate a set angle around the connection device. Provided is an assembling apparatus for an assembled guardrail. The assembled guardrail can avoid the Faraday cage effect during electrostatic spraying, exhibits better anti-corrosion performance, may adapt to different terrains such as slopes, and has a wide application range.
