Building outer wall composite insulation board

Abstract

The invention relates to the technical field of building outer wall insulation, in particular to a building outer wall composite insulation board. The building outer wall composite insulation board comprises an adhesion layer, an insulation layer and an exterior trim layer. The insulation layer is arranged on the outer side of the adhesion layer, and the exterior trim layer is arranged on the outer side of the insulation layer. The insulation layer comprises a base layer and a padding layer. Due to the fact that a single insulation board on a building outer wall is affected by the temperatureto generate the micro deformation, the deformation effects of the insulation boards which are laid in a large area can be accumulated and amplified, the deformation of the insulation boards exceeds the deformation range of adhesion layers, the fixation of the insulation boards can be affected, and the insulation effect of the building outer wall is affected. As a result, the base layer and the padding layer are arranged on the insulation layer of the building outer wall composite insulation board, deformation movement is conducted through the cooperation of floccus insulation materials in thepadding layer and the air between the floccus insulation materials, the deformation effect of the external environment on the base layer is buffered, the deformation quantity of the insulation board can be located within the reasonable range, and the insulation effect of the building outer wall composite insulation board is improved.

AI Technical Summary

Problems solved by technology

[0003] After long-term use of the current building exterior wall insulation boards, there will be structural problems: looseness or even falling off between the insulation boards will greatly affect the function of the insulation boards, and at the same time leave a safety hazard; especially in buildings with a length of ten years. Over the years of external environmental changes, the slight deformation of the insulation board has accumulated over the years, reducing the structural stability of the insulation board and affecting the insulation effect of the insulation board

[0004] In the prior art, there are also some technical solutions of composite thermal insulation boards for building exterior walls. For example, a Chinese patent with application number 2008102020254 discloses a composite thermal insulation board for wall thermal insulation and its manufacturing and use methods: The composite thermal insulation board is composed of a panel, a thermal insulation body, a combined fixed sleeve, a positioning expansion sleeve and bolts, a T-shaped connecting strip, a T-shaped connecting plate, a corner connecting plate and a core-pulling anchor; the composite thermal insulation board can be prepared in advance, or Combined installation on site; when in use, the composite thermal insulation board is fixed on the outer wall of the building through the positioning expansion sleeve and bolts, and the composite thermal insulation board is connected to the building under the action of the combined fixing sleeve, positioning expansion sleeve, bolts and other connectors. The outer wall forms a flat and stable whole; this technical solution can not only permanently protect the thermal insulation material of the wall, but also improve the fire protection level, meet the requirements of different outer wall finishes, shorten the construction period, and reduce the project cost ; But in this technical scheme, the problem caused by the gradual accumulation of the error of the micro-deformation of the thermal insulation board after long-term use is not solved, making it difficult to guarantee the thermal insulation effect of the thermal insulation board used by the technical scheme for a long time
