Design method of recycled concrete composite self-insulation building block

Abstract

The invention discloses a design method of a recycled concrete composite self-insulation building block. The method comprises the following steps of 1, setting parameters of the recycled concrete composite self-insulation building block body; 2, determining the mix proportion of a recycled concrete base material in the recycled concrete composite self-insulation building block body; 3, obtaining the heat conductivity coefficients of the recycled concrete base material and the thermal insulation material in the recycled concrete composite self-insulation building block body; 4, setting distribution of through holes in the recycled concrete composite self-insulation building block body; 5, carrying out finite element analysis on the thermal performance of the recycled concrete composite self-insulation building block body; and 6, manufacturing the recycled concrete composite self-insulation building block body. The method is simple in step and reasonable in design, the recycled concretebase material of the recycled concrete composite self-insulation building block and the block structure of the building block body are optimized so as to meet the requirement for the insulation performance of the outer wall of the residential building in the cold region under the 75% building energy-saving standard, and practicability is high.

Description

technical field [0001] The invention belongs to the technical field of recycled concrete composite self-insulating blocks, and in particular relates to a design method of recycled concrete composite self-insulating blocks. Background technique [0002] Building exterior wall insulation systems mainly include exterior wall insulation, exterior wall interior insulation, sandwich insulation walls, recycled concrete composite self-insulation block walls. External wall insulation is the main means of building external wall insulation at present. External wall insulation has the advantages of eliminating thermal bridges and increasing the use area, but its disadvantages are also obvious. The construction technology is difficult, there are many procedures, and the construction period is long. The outer surface of the outer wall will crack and fall off for a long time; in addition, the outer insulation layer made of flammable materials has also caused many major fire accidents. [...
