Description

technical field [0001] The invention relates to the technical field of thermal insulation of building exterior walls, in particular to a prefabricated thermal insulation device for building exterior walls. Background technique [0002] With the continuous advancement of the construction of the western region, there are more and more construction sites in the western region. For the convenience of work, construction workers usually use prefabricated buildings to build temporary residences next to the construction site. Due to the huge temperature difference between day and night in the western region, and the thermal insulation performance of prefabricated buildings is poor, the internal temperature of the building will drop rapidly at night, which will affect workers. normal rest. To solve this problem, it is generally solved by installing thermal insulation devices on the exterior walls of buildings. However, traditional thermal insulation devices for external walls can on...

Problems solved by technology

For the convenience of work, construction workers usually use prefabricated buildings to build temporary residences next to the construction site. Due to the huge temperature difference between day and night in the western region, and the thermal insulation performance of prefabricated buildings is poor, the internal temperature of the building will drop rapidly at night, which will affect workers. normal rest

To solve this problem, it is generally solved by installing thermal insulation devices on the exterior walls of buildings. However, traditional thermal insulation devices for external walls can only block the transfer of heat. For the extremely low nighttime temperature in the western region, the thermal insulation effect is not good. , but it is unrealistic to install a heating system in such an environment as a construction site, and it will consume a lot of power to adjust the temperature completely through indoor air conditioning. At present, there is an urgent need for a device that can effectively maintain the temperature of the wall

On the other hand, the external wall thermal insulation device is installed on the external wall of the building in a plate-like structure. Due to processing errors, there will be certain differences in the weight and structure of each thermal insulation device, and the construction site will cause The ground vibrates more frequently, and this vibration is transmitted to the thermal insulation device installed on the outer wall of the building. The difference in weight and structure will cause different vibration frequencies and vibration amplitudes of different thermal insulation devices, which will lead to different thermal insulation devices. Relative compression will be generated between them, thus affecting the installation strength and structural stability of the thermal insulation device

Traditional building exterior wall insulation devices lack the necessary ventilation system, and moisture is easy to accumulate inside the insulation device, which affects the service life of the insulation device
