Technical Field
The utility model belongs to the technical field of building structure and specifically relates to a parapet prevents flooding structure that ftractures.
Background
The roof of the building is often added with structures such as pipelines, chimneys or parapet walls, and the structures are vertically arranged with the roof of the building. In order to avoid the cracks at the horizontal and vertical intersection points, the waterproof layer of the roof needs to extend a section to continuously cover the intersection points and the vertical plane, and the design of the leakage prevention is called as a flashing structure. Before the waterproof layer is laid, the horizontal and vertical joint surfaces are plastered and leveled, and then a waterproof additional layer is laid, and finally the waterproof layer is covered on the vertical surface and the joint position.
The existing parapet wall is mostly built by bricks, and cast-in-place concrete is pressed on the top of the parapet wall for water prevention; the cast-in-place concrete has small layer thin vibration pressure difference due to the jacking quantity, and is difficult to maintain in place; the difference between the linear expansion coefficient of the concrete and the linear expansion coefficient of the brick masonry is large; when the concrete is pressed to be a long distance, the deformation of the pressed concrete is large under the influence of the ambient temperature, and the cracking phenomenon is very common; when the parapet contains more water, rain and snow directly enter the parapet through the cracks of the coping and then gradually permeate into the indoor wall, so that the indoor wall is polluted.
In order to improve the waterproofness of the waterproof coiled material head, a cornice is generally formed above the waterproof coiled material head of the parapet wall by using bricks, and a plastering layer is smeared on the surface of the cornice for waterproofing; however, the difference between the linear expansion coefficients of the plastering layer and the brick masonry is large, and under the influence of the temperature difference of the natural environment, the plastering layer and the brick masonry are cracked and peeled off, so that the brick masonry is exposed, rainwater directly permeates into a wall body from mortar joints, and the leakage phenomenon occurs.
