Thermal bridge dispersion type built-in thermal insulation concrete structure system

Abstract

The invention relates to a thermal bridge dispersed built-in thermal insulation concrete structure system. It includes load-bearing concrete structure layer, thermal insulation material layer and concrete protection layer from the inside to the outside. There are reserved holes at regular intervals along the vertical and horizontal directions of the thermal insulation material layer. There are transverse steel bars, load-bearing concrete structure layer and concrete protection layer in the holes. The steel bars in it are connected to form a tension bridge with the poured concrete, and an inner insulation material layer slightly larger than the reserved hole is fixed on the inner side of the load-bearing concrete structure layer corresponding to the reserved hole. The invention can disperse the thermal bridge effect, balance the heat transfer of the building envelope, significantly reduce the thermal bridge effect, and have good thermal insulation performance; the built-in thermal insulation layer is safe to use and can last the same life as the structure, greatly exceeding the external thermal insulation system 25-year service life; it can eliminate hidden dangers such as easy cracks, hollowing, leakage, and shedding caused by the use of external wall paste and external insulation layers. It combines many advantages such as thermal insulation, earthquake resistance, environmental protection, short construction period, and low cost.

Description

technical field [0001] The invention relates to the field of engineering construction, in particular to a thermal bridge dispersed built-in thermal insulation concrete structure system. Background technique [0002] In the construction industry, the heat preservation technology and process of the building energy-saving and thermal insulation walls commonly used at present is that the formwork needs to be supported first, and the concrete wall is poured. After the concrete reaches a certain strength, the formwork is removed, and then the wall is made. Body insulation, usually using glue bonding method, paste the insulation board on the wall, or use steel wire or other materials to nail and hang the insulation board on the wall. After many complex processes, the exterior decoration is done. The construction process of this cast-in-place concrete and its wall insulation process is complicated, the speed is slow, and the wall is easy to crack and hollow. Poor thermal insulatio...

Problems solved by technology

The thermal bridge part not only has serious heat loss, but more importantly, water vapor will condense on its inner surface under certain conditions to form condensed water. If the condensed water stays for a long time and cannot be dissipated as soon as possible, the inner surface of the thermal bridge will absorb air. Dust and other substances in it, and the damp inner surface is very easy to breed mold and other microorganisms, resulting in mildew and hair growth on the inner wall of the house, which not only affects the normal use and durability of the building, but also has a direct impact on the indoor living environment. directly endanger people's physical and mental health
