Deformation joint structure for light rail elevated station and construction method thereof

Abstract

The invention discloses a deformation joint structure for a light rail elevated station and a construction method thereof. The deformation joint structure is arranged between floor slabs arranged at two sides of a deformation joint, and comprises a water stop, a fireproof plate and multiple stainless steel plates, wherein the fireproof plate and the water stop are fixed to the floor slabs at the two sides through bolts which are arranged at intervals by pressing the stainless steel plates; the fireproof plate is formed by a fireproof upper plate, a fireproof lower plate and a fireproof material filled between the fireproof upper plate and the fireproof lower plate. According to the deformation joint structure for the light rail elevated station, disclosed by the invention, under the action of various deformation influence factors, not only is the requirement of expansion deformation of the deformation joint met, but also the requirements of fire prevention, heat preservation and water prevention of the deformation joint are considered; the deformation joint structure is simple in structure and construction technology, reliable in performance, convenient in construction and easy in overhauling and replacement, and can be widely applied to a large-area floor deformation joint in a public place which has higher requirement on fireproof performance and is always in larger temperature difference.

Description

technical field [0001] The invention relates to a deformation joint structure of a light rail elevated station or building floor, in particular to a structure of a deformation joint fire-stopping belt and a construction method; Waterproof, anti-corrosion and fireproof construction. Background technique [0002] With the diversification of social needs for traffic building functions, the floor structure layout is becoming more and more complex. In order to solve the problem of over-length and excessive floor area, it is usually necessary to set up deformation joints. In terms of the structural function of deformation joints, in addition to meeting the structural deformation requirements On the premise of the premise, but also take into account the fire protection, waterproof, moisture and thermal insulation and other protective properties. It is difficult to meet the above performance requirements for the traditional floor deformation joint fire resistance belt due to the fo...
