A roof edge beam profile

Abstract

The invention provides a top plate side beam section bar. The top plate side beam section bar has a framework structure, and comprises a substrate shaped like a Chinese character 'shan', wherein the substrate comprises a base; a front bracket, a middle bracket and a back bracket are vertically arranged on the base; a cover plate comprises an outer edge-covered connecting plate, an outer envelope connecting plate and an L-shaped connecting member; the substrate, the cover plate and a transition plate are integrated together; the front end of the cover plate is directly connected with the front bracket of the substrate, and the back end of the cover plate is connected with the back bracket of the substrate through the transition plate. The top plate side beam section bar is arranged on the top of a carriage, and water accumulation on the top of the carriage is prevented, so that water seepage on the top of the carriage can be effectively prevented, and the rain-proof performance of a cabin body is improved greatly. Moreover, the top plate side beam section bar is simple in structure, convenient for construction and high in production efficiency, and the production and labor costs are greatly reduced.

Description

technical field [0001] The invention relates to a section material, in particular to a top plate edge beam section material for preventing water accumulation on the top of the compartment. Background technique [0002] The box body of the carriage or vehicle-mounted shelter is generally a hexahedron, which is mainly assembled by six plates and eight corner-wrapped parts. When the plates are assembled, two vertically adjacent plates need to be connected by corner-wrapped parts. Due to the thicker material of the corner parts, a protruding closed loop is surrounded by the corner parts around the top of the carriage or shelter, which is higher than the outer cover of the box roof, which is easy to accumulate rainwater. In order to prevent the top of the box from seeping, the corner parts are installed , although the sealant is applied on the contact surface between the corner-wrapped parts and the outer panel, with the long-term water accumulation and the aging of the sealant, ...

Problems solved by technology

Due to the thick material of the corner parts, the top of the carriage or shelter is surrounded by the corner parts to form a protruding closed loop which is higher than the outer cover of the box roof, which is easy to accumulate rainwater. , although the sealant is applied on the contact surface between the corner-wrapped parts and the outer panel, with the long-term accumulation of water and the aging of the sealant, it is easy to cause water seepage on the top of the box, which reduces the rainproof performance of the compartment or shelter
