Abstract

The invention discloses a design method of a recycled concrete composite self-insulating block, which comprises the following steps: 1. Setting parameters of the recycled concrete composite self-insulating block; 2. The recycled concrete base in the recycled concrete composite self-insulating block The determination of material mix ratio; 3. Obtaining the thermal conductivity coefficient of recycled concrete base material and thermal insulation material in recycled concrete composite self-insulating blocks; 4. The setting of through-hole distribution in recycled concrete composite self-insulating blocks; 5. Recycled concrete Finite element analysis of thermal performance of composite self-insulating blocks; 6. Manufacture of recycled concrete composite self-insulating blocks. The method of the invention has simple steps and reasonable design, and optimizes the recycled concrete base material of the recycled concrete composite self-insulating block and the block structure of the block, so as to meet the requirements for thermal insulation performance of residential building exterior walls in cold regions under the 75% building energy saving standard. Strong practicality.

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. [...
