Description

Technical Field

[0001] This utility model relates to the technical field, and in particular to a fixing nail and an insulated wall including the same. Background Technology

[0002] As a core component of thermal insulation technology, insulated walls have extremely wide applications, covering almost all scenarios requiring controlled heat transfer. Insulated walls typically consist of an insulation layer and fixing nails, with the insulation layer secured by the nails. The performance of the fixing nails directly affects the safety and durability of the insulated wall.

[0003] In existing technologies, traditional fasteners are mostly made of metal (such as steel nail rods) or single plastic materials (such as polyamide PA6). In practical applications, they suffer from significant thermal bridging effects, insufficient tensile strength, and poor weather resistance. In addition, existing fastener structural designs mostly rely on the principle of expansion friction, which is not adaptable to the base wall materials (such as hollow blocks and lightweight concrete), and is prone to anchorage failure.

[0004] Therefore, there is a need for a new type of fixing nail and an insulated wall that includes it, which can overcome at least one of the above-mentioned problems. Utility Model Content
