Construction method of flashing structure at wall foot of steel structure PVC waterproof roof

Abstract

The invention discloses a construction method of a flashing structure at a wall foot of a steel structure PVC waterproof roof. A roof is comprised. The method comprises the following steps of Step 1, clamping and connecting an annular iron block at an inner side end opening of a drainage pipe, and attaching a protective film for closed protection; Step 2, maintaining the side surface of a settling tank to be an inclined slope surface, and cutting the upper layer position of a parapet wall to form an end collecting groove; Step 3, cleaning the cut position; Step 4, laying a mortar layer at the bottom of the settling tank, and performing still standing for drying and shaping; Step 5, baking the surface of the roof, and pasting waterproof coiled materials onto the surface of the roof, fitting the waterproof coiled materials to a mortar layer and a transition round corner position, and attaching the end collecting position to the side surface of the parapet wall; Step 6, curling the end part of the waterproof coiled materials to form a winding drum, clamping and connecting the winding drum into the end collecting groove, and performing baking, pasting and shaping; Step 7, drawing a line to mark the position of the end opening of the drainage pipe; Step 8, cutting the line drawing position; and Step 9, completing the flashing structure construction. By such a method, the construction convenience and accuracy can be greatly improved, safety and high efficiency are guaranteed, and popularization and application are facilitated.

Description

technical field [0001] The invention relates to the technical field of flashing structures, in particular to a construction method of a flashing structure at the foot of a steel structure PVC waterproof roof. Background technique [0002] In the construction process of the steel structure roof, in order to ensure the safety of use, it is necessary to carry out waterproof construction, and at the corner of the edge parapet, it is necessary to build a flashing structure to ensure drainage and waterproof effects. [0003] However, most of the existing wall corner flashing structure and construction are directly attached to the waterproof membrane at the corner position, which will cause vertical bending at the corner position, which is easy to be damaged and affects the waterproof effect, leakage will occur, and the Raising the height of the edge will prevent rainwater from entering the drainage pipe smoothly, and will also cause blockage of the drainage pipe, which is not cond...
