Building exterior wall concrete insulation board and preparation process thereof

Abstract

The invention discloses a building external wall concrete insulation board and a preparation process of the building external wall concrete insulation board, and belongs to the technical field of building insulation boards. The steel bar buckling body is composed of upper glass fiber gridding cloth, lower glass fiber gridding cloth and steel bar columns, wherein the upper glass fiber gridding cloth and the lower glass fiber gridding cloth are distributed up and down, and the steel bar columns are annularly connected to the outer side of the upper glass fiber gridding cloth and the outer side of the upper glass fiber gridding cloth. The upper ends and the lower ends of the multiple steel bar buckling bodies are connected into the concrete base layer and the exterior mortar layer in an embedded mode correspondingly, the concrete base layer and the exterior mortar layer can be fused and bonded at the hollowed-out positions of the steel bar buckling bodies, and the mixed heat preservationlayer is anchored between the concrete base layer and the exterior mortar layer. The stability of connection between every two of the mixed heat preservation layer, the concrete base layer and the exterior mortar layer is effectively improved, the overall mechanical strength of the heat preservation plate is effectively enhanced, and falling of the external wall heat preservation structure is notlikely to be caused.

Description

technical field [0001] The invention relates to the technical field of building thermal insulation boards, and more specifically relates to a concrete thermal insulation board for building exterior walls and a preparation process thereof. Background technique [0002] With the progress of society, our natural energy is endlessly developed and used so that it becomes less and less, and energy saving has now become a trend. However, there is a contradiction between energy saving and comfort, which needs to be resolved through the improvement and perfection of building technology. [0003] External wall thermal insulation is a scientific, efficient thermal insulation and energy-saving technology, that is, thermal insulation materials are placed on the outside of the building wall envelope, so that not only can achieve the purpose of thermal insulation, but also protect the main structure of the building and prolong the life of the building. The service life of the building, th...

Problems solved by technology

[0004] However, due to the difference in mechanical properties, especially the tensile strength, between the insulation materials used for external wall insulation and the concrete blocks used for masonry building walls, there are differences in deformation between the insulation materials and concrete blocks during long-term use. , leading to the inability of the thermal insulation material to firmly adhere to the concrete block of the building wall, which in turn leads to cracks in the thermal insulation material or even falling off the building wall directly, affecting the thermal insulation effect of the outer wall of the building, resulting in construction period, economic and social benefits, etc. Loss
