External wall heat preservation formwork and production method thereof

Abstract

The invention provides an external wall heat preservation formwork and a production method thereof. According to the adopted scheme, the external wall heat preservation formwork comprises an inorganic wrapping organic particle layer and an organic heat preservation layer, wherein the organic heat preservation layer is located on one side of the inorganic wrapping organic particle layer, gridding cloth is arranged between the inorganic wrapping organic particle layer and the organic heat preservation layer, and the inorganic wrapping organic particle layer, the gridding cloth and the organic heat preservation layer are integrated. The gridding cloth is arranged between the inorganic wrapping organic particle layer and the organic heat preservation layer, a good enhancement effect is achieved, stress concentration is avoided, and the stability of the performance of a whole formwork body is guaranteed; and meanwhile, the weight and thickness are reduced, the high volume weight performance is achieved, construction is easy, the construction efficiency is improved, and cost is saved.

Description

technical field [0001] The invention relates to the technical field of building thermal insulation, in particular to an external wall thermal insulation template and a production method thereof. Background technique [0002] The implementation of relevant requirements such as building energy-saving standards and building fire protection regulations has promoted the rapid development of wall insulation materials. In order to make full use of the thermal insulation effect of organic thermal insulation materials and meet the GB50016-2014 fire protection regulations, the current cast-in-place thermal insulation external formwork is widely used to scrape a 5cm non-combustible fireproof protective layer on the outside of Class B fireproof insulation materials. At present, almost all use 2 -3cm polystyrene particle mortar or vitrified bead mortar is used as a transition layer, and a 3-2cm mortar protective layer is added to meet the requirements of a 5cm non-combustible fireproof p...

Problems solved by technology

However, since the inorganic material-wrapped organic particle layer is mainly composed of inorganic materials (accounting for about 90%), the inorganic-wrapped organic particle layer and the organic thermal insulation material layer mainly composed of inorganic materials belong to two material layers with very different properties, causing them The shrinkage is different. When combined together, due to the greater shrinkage of the organic thermal insulation material layer, the entire composite formwork will be bent and deformed, and there will be hollowing between the wall and the wall, and there will be a high degree of safety. Hidden danger

In this regard, the thickness of the inorganic material to wrap the organic particle layer and the protective layer is often thickened, which will also appear as described above, "the overall thickness of the outer formwork will become thicker and heavier, and the construction will become heavier and heavier. Restricted and severely elevated security concerns" same issue
