Abstract

The invention provides a combined composite material handrail fixing piece. The combined composite material handrail fixing piece is integrally made of composite materials and comprises an upper lantern ring, a lower lantern ring and a positioning seat used for being fixed on a pipe piece. The positioning seat is provided with a supporting plate connected with the lower lantern ring. The upper lantern ring is provided with a connecting plate which is matched with the supporting plate to complete fixing to enable the upper lantern ring and the lower lantern ring to form a closed lantern ring, and the lantern ring is used for fixing a handrail pipe. The combined composite material handrail fixing piece is novel in structure, is made of the composite materials through compression molding, ishigh in strength, fixes the handrail pipe in a mode that the upper lantern ring and the lower lantern ring are matched, facilitates the installation of the handrail, reduces the installation difficulty, is easy to disassemble at the same time, and facilitates the maintenance of the handrail.

Description

technical field [0001] The invention is applied to the technical field of emergency evacuation of shield tunnels and subway platforms, and in particular relates to a combined composite handrail fixing part. Background technique [0002] Handrails shall be provided above the shield section and the evacuation platform of the subway passage, and the handrails of the evacuation platform are mainly made of stainless steel or polymer composite materials. Stainless steel handrails are expensive and have poor tactile sensation. According to the opinions of experts in acceptance inspection before the trial operation of Changsha Line 3 / 5, stainless steel handrails have a risk of electrical conduction, and need to be grounded and the process is relatively complicated. Handrails made of polymer materials are non-conductive, have A-level fire performance, are relatively cheap, have good touch and feel, and have average durability. They can be used as handrail materials for evacuation pla...
