Parapet construction method

Abstract

The invention relates to the field of building construction, and provides a parapet construction method aiming at the problem that water seepage and saltpetering easily occur at the joint of a parapetand a roof. The method comprises the following steps: S1, reserving a groove: reserving the groove for building a parapet at the top of a house; S2, constructing a injecting waterproof concreteinto the groove reserved in the step S1, and piling up wall bricks at the bottommost layer of the parapet before the concrete begins to solidify, so as to enable the wall bricks arranged in the groove to be partially soaked in the waterproof concrete; S3, piling up the parapet: piling up residual wall bricks of the parapet; S4, painting an exterior wall: painting a layer of waterproof concrete outside the wall body; and S5, smearing a waterproof layer: applying a waterproof layer outside the waterproof concrete layer through coating. The waterproof concrete is poured into the groove reservedin the roof at first, and then the base layer of the parapet is built in the waterproof concrete, so that a gap is not likely to exist between the base layer of the parapet and the roof, and the situation that water leakage and salfpetering are likely to happen at the joint of the parapet and a house is reduced.

Description

technical field [0001] The invention relates to the field of building construction, more particularly, to a parapet construction method. Background technique [0002] The parapet, also known as the eave wall, is a way of connecting the roof and the outer wall. As a measure for the railing on the roof or the shape of the house, it can prevent people from falling. [0003] The parapet is usually a wall that is rebuilt on the roof after the house is built, so there is easy to have a joint between the parapet and the roof. It penetrates to the outer surface of the building body through the joint seam. At the same time, the parapet is generally a concrete wall, and ordinary concrete is generally silicate. When silicate encounters air or moisture in the wall, silicate ions are easily hydrolyzed to generate hydroxide, which is easy to form with metal. The ions combine to form hydroxides with low solubility. When the temperature rises, the water vapor easily evaporates, so that th...

Problems solved by technology

At the same time, parapets are generally concrete walls, and ordinary concrete is generally silicate. When silicate encounters air or moisture in the wall, silicate ions are prone to hydrolysis to generate hydroxide ions, which are easy to react with metals. Ions combine to form hydroxides with low solubility. When the temperature rises, water vapor evaporates easily, causing hydroxides to precipitate from the wall. With the gradual evaporation of water, hydroxides are precipitated on the surface of concrete cement, making The original decorative paint or paint is lifted up and no longer adheres to the wall, resulting in whitening and efflorescence, which is difficult to remove and easily affects the appearance of the house. Therefore, there is still room for improvement
