Building outer wall and protection process thereof

Abstract

The invention provides a building outer wall. The building outer wall comprises a first layer and a second layer, the first layer and the second layer are sequentially built upwards to form the building outer wall, the first layer is formed by transversely laying two layers of building blocks, the second layer is formed by transversely laying one layer of building blocks, the building blocks of the second layer are arranged in a staggered mode relative to the building blocks of the first layer, and the building block comprises a concrete-based waterproof brick. Permeable active waterproof particles are added into the concrete-based waterproof brick used for the building outer wall, after the building block is used for dozens of years, the waterproof effect of a polyurethane waterproof coating layer and a second asphalt felt is weakened, and when a gap exists in the building block, the waterproof effect is weakened; and at the moment, a curing agent solution is injected into the concrete-based waterproof brick through a drainage pipe, the permeable active waterproof particles are dissolved in the curing agent solution to form gel, then the gaps of the building block are filled withthe gel, loose sand is bonded into tight waterproof solids like glue after a waterproof agent is solidified, the waterproof effect is improved, and the service life of the building outer wall is prolonged.

Description

technical field [0001] The invention belongs to the technical field of buildings, and in particular relates to a building exterior wall and its protection technology. Background technique [0002] Let A~B be a wall, if the A~B wall line can cut the relevant enclosure structure, it is an inner wall, otherwise it is an outer wall. From an architectural point of view, the enclosure of a building to form an indoor and outdoor boundary component is called an exterior wall. Its functions are: bear a certain load, shelter from wind and rain, thermal insulation, noise prevention, fire safety, etc. [0003] The waterproofing of building exterior walls should have the basic function of preventing rainwater and snowwater from intruding into the wall, and should have the properties of anti-freezing and thawing, high and low temperature resistance, and wind load. The exterior wall of a building is built by building blocks skin by skin. Building blocks are semi-finished building materia...

AI Technical Summary

Problems solved by technology

[0004] After more than ten or twenty years of use of building blocks, there will be gaps inside, which will weaken the waterproof effect. We often see that the walls of old buildings seep water into the room on rainy days. The reason is that there are cracks inside the walls. At present The best solution is either to demolish the old buildings, or to repaint the waterproof layer on the outside of the wall, but the amount of work is large, and it is not suitable for slight or partial water seepage.
