Description

Technical Field

[0001] The utility model belongs to the technical field of wall bodies, and in particular relates to a fully hidden nail bracket structure of a sandwich panel with a top pressing and edge finishing flush with a wall surface. Background Art

[0002] Wall sandwich panels are widely used in China, with their advantages of easy installation, high waterproof performance, and quick construction being particularly evident. Traditionally, sandwich panel parapets have been constructed with trimmed edges that protrude from the wall, using either exposed or concealed nailing. Rainwater dripping from the protruding edges of these panels can cause irregular water marks on the wall over time. The exposed nailing joints in the sandwich panels can also expand and deform due to seasonal temperature fluctuations, causing the nail holes to expand. Rainwater from the side walls can then seep into the wall sandwich panels through the expanding nail holes, compromising the panels' waterproof and thermal insulation properties.

[0003] To this end, we proposed a fully hidden nail bracket structure for sandwich panels with top pressing and edge finishing flush with the wall to solve the above problems. Utility Model Content

[0004] The main purpose of the utility model is to provide a fully hidden nail bracket structure for sandwich panels with flush top and edge pressing.
