Description

Technical Field

[0001] This utility model relates to the technical field of building curtain wall and floor profiles, specifically to a sound-insulating and heat-insulating aluminum alloy profile. Background Technology

[0002] Conventional flooring can be divided into two types: flat-edge flooring and tongue-and-groove flooring. Flat-edge flooring is fixed to the ground with nails and anchors, making it difficult to remove and reuse after installation, and therefore unsuitable for underfloor heating systems. Tongue-and-groove flooring is widely used because its locking mechanism allows for removal and reinstallation. Tongue-and-groove flooring has grooves and tongues on the sides, and the pieces overlap during installation, making installation and maintenance more convenient.

[0003] For example, Chinese patent CN222044843U discloses an aluminum alloy floor that does not require connectors, which includes several floor units that are spliced ​​together. The floor unit is made of aluminum alloy in one piece and includes a tenon and a mortise. The tenon and the mortise are located at both ends of the floor unit, and both extend outward from the top of the floor unit. The tenon and the mortise cooperate to connect two floor units. The top of the two sides of the floor unit adjacent to the tenon and the mortise are chamfered to form an inclined chamfer.

[0004] The existing technology described above features tenons and mortises with matching step hooks and grooves, as well as matching limiting posts and grooves. These mechanisms allow for a certain degree of rotation at the joint between floor units without damaging the mortise and tenon structure. However, this joint structure makes it prone to disengagement of the mortise and tenon joint on the other side when one floor unit warps, resulting in unstable connections. Furthermore, the existing assembly structure has poor tightness and inadequate sound and heat insulation. Therefore, the existing technology requires further improvement and development.
