Outer wall external heat-preservation fire-proof crack-resisting protecting device and construction method

Abstract

The invention discloses an outer wall external heat-preservation fire-proof crack-resisting protecting device and a construction method thereof. The construction method comprises the steps that galling treatment is conducted on the wall surface; a first crack-resisting mortar layer is arranged on the wall surface subjected to galling treatment; after the arrangement time of the first crack-resisting mortar layer exceeds the predetermined time, a second crack-resisting mortar layer is arranged on the surface of the first crack-resisting mortar layer; gridding cloth is arranged on the second crack-resisting mortar layer and subjected to flat twining and then leveling operation; and the first crack-resisting mortar layer and the second crack-resisting mortar layer are crack-resisting mortar made from cement, sand, rubber powder, celluloses and water repellents, and the thickness sum of the first crack-resisting mortar layer and the second crack-resisting mortar layer is larger than or equal to 1.5 cm. Through use of the crack-resisting mortar made from the cement, the sand, the rubber powder, the celluloses and the water repellents, when the thickness sum of the first crack-resisting mortar layer and the second crack-resisting mortar layer is larger than or equal to 1.5 cm, and while the fire-proof function is achieved, cracking does not occur, construction is easy, cost is low, and flatness is easy to ensure.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to an external thermal insulation, fire, crack and anti-crack protection device for an external wall and a construction method. Background technique [0002] With the development of science and technology, the energy crisis continues to intensify, and energy transformation is required. While improving energy utilization efficiency, more new energy that produces less or no pollution should be used to replace traditional fossil energy. In the process of energy transformation, in addition to the energy transformation required by transportation and industry, energy conservation and emission reduction in the construction industry has also become the development trend of the construction industry. [0003] The energy saving and emission reduction in the existing construction industry is mainly through the use of insulation layers on the outer walls to reduce heat conduction,...
