Abstract

The invention relates to a flat-joint and detachable type roof deformation joint and a construction method thereof, and belongs to the technical field of buildings. The deformation joint is characterized in that the interiors of reinforced concrete structure beams at the two sides of the deformation joint are embedded with round steel, each reinforced concrete structure beam is provided with an angle iron, the outer side of each angle iron is provided with a concrete retaining sill, each angle iron is provided with an additional waterproof layer, a detachable rubber water stop belt is arranged between the two angle irons above the deformation joint, and is provided with a steel plate pressing strip, the steel plate pressing strip, the detachable rubber water stop belt and the angle irons are screwed, fastened and connected through nuts and threads at one ends of the round steels, a roof waterproof layer is provided with a roof heat insulation layer, a leveling layer and a roof rigid protecting layer, a deformation joint heat insulation layer is arranged between the two angle irons, a cover plate is arranged in the roof rigid protective layers, a gap is formed between the cover plate and the roof rigid protective layer, a flexible plate strip is arranged in the gap, and the upper part of the flexible plate strip is fully embedded with sealant. The deformation joint has the advantages that the setting requirements of various deformation joints, such as earthquake-proof joints, telescopic joints and settlement joints, are met, the strength is high, the wear-resisting performance is good, and the maintenance is convenient.

Description

technical field [0001] The invention relates to a deformation joint, in particular to a flat joint type, detachable roof deformation joint and a construction method thereof, which belong to the technical field of construction. Background technique [0002] According to the requirements of architectural design codes, reinforced concrete structures need to set deformation joints every 50 meters or so. Among them, the roof deformation joints need to meet the roof waterproof requirements while meeting the deformation requirements of the main structure. The general method of roof deformation joint construction is to build 400-600mm high vertical walls with bricks or concrete on both sides of the deformation joints, the roof waterproof layer is turned over along the vertical walls for flooding treatment, and metal or concrete cover joints are set across the upper vertical walls. The roof of the building is divided into several relatively independent units due to the existence of ...
