The invention relates to a horizontal joint of a prefabricated sandwich thermal insulation external wall and construction steps of the horizontal joint of the prefabricated sandwich thermal insulation external wall. The horizontal joint of the prefabricated sandwich thermal insulation external wall comprises prefabricated sandwich thermal insulation external walls, every two prefabricated sandwich thermal insulation external walls are formed by being spliced, polyurethane insulation boards are embedded in the prefabricated sandwich thermal insulation external walls close to spliced parts, the spliced part of every two prefabricated sandwich thermal insulation external walls is formed by being filled with the polyurethane insulation boards and splicing grouting materials, therefore, thermal insulation and water proofing are integrated; the polyurethane insulation boards are arranged in the shapes of rectangles, one end of each polyurethane insulation board is embedded into the corresponding prefabricated sandwich thermal insulation external wall, and the other end of each polyurethane insulation board extends out of the corresponding prefabricated sandwich thermal insulation external wall; the distance of each polyurethane insulation board embedded into the corresponding prefabricated sandwich thermal insulation external wall is 50 millimeters, and the distance of each polyurethane insulation board extending out of the corresponding prefabricated sandwich thermal insulation external wall is 15 millimeters; according to the invention, the thermal insulation and water proofing are combined to improve the insulation performance of the horizontal joints of the external walls.
Description
technical field [0001] The invention relates to a horizontal joint of a prefabricated sandwich thermal insulation outer wall and construction steps thereof, and belongs to the field of passive ultra-low energy consumption buildings and prefabricated buildings. Background technique [0002] In recent years, with the country's rapid advancement of energy conservation and emission reduction work and the rapid development of building energy conservation, more and more new forms of energy-saving buildings have gradually entered people's lives, and more and more passive super low-energy buildings have emerged. Passive ultra-low energy buildings have higher thermal insulation and energy efficiency requirements for external walls. For prefabricated passive ultra-low energy buildings, the heat insulation treatment at the horizontal joints is the key. The existing assembly technology is to fill the horizontal joints with grouting material. This method has the problem that the groutin...
