Viaduct drop-off deformation seam structure and construction method of viaduct drop-off deformation seam structure

Abstract

The invention relates to a viaduct drop-off deformation seam structure, which is arranged between a box type steel structure and a concrete structure, wherein one side of the concrete structure corresponding to the box type steel structure is fixedly provided with an embedded steel element, a steel support seat facing the inside of a deformation steam is correspondingly welded with the upper part of the embedded steel element and the upper part of the box type steel structure, waterproof coiled materials are paved on the steel support seat in the through length direction of the deformation seam, a steel press plate is placed on the waterproof coiled materials, and asphalt paste is respectively embedded in junction parts of the two sides of the steel press plate with the box type steel structure and the concrete structure. A groove-shaped layer board is arranged in the through length direction at the lower part of the deformation seam, one side of the groove-shaped layer board is connected with a lower wing edge of the box type steel structure, the other side of the groove-shaped layer board is fixedly connected with a hanging connecting element provided with a bent hook at the bottom end, and the upper end of the hanging connecting element is fixedly connected with the steel support seat arranged at one side of the concrete structure. The viaduct drop-off deformation seam structure solves the technical problems that the traditional pavement deformation seam structure cannot meet the requirement of various kinds of protection performance of the pavement deformation seam between a drop-off platform and a viaduct of a railway station building viaduct waiting hall under the deformation condition.

Description

technical field [0001] The invention relates to a structure of a deformation joint on a building floor and a construction method thereof, in particular to a structure of a deformation joint between a viaduct and a drop-off platform and a construction method thereof. Background technique [0002] The elevated waiting hall of the railway station building is generally located above the platform and the train track, and the viaduct that passengers pass to the elevated waiting hall of the station is connected to the drop-off platform. In order to eliminate the cracking and uplift of the road surface caused by structural deformation and improve the smoothness of the road surface and driving comfort, deformation joints should be set between the viaduct and the drop-off platform. The viaduct is a box-section steel structure, and the drop-off platform is a concrete beam-slab structure , the asphalt concrete pavement of the bridge deck is laid on the deformation joint between two diff...
