Novel metal nail sleeve for fixing thermal insulation layer

Abstract

The present invention relates to the technical field of construction mounting fasteners, and especially, to a novel metal nail sleeve for fixing a thermal insulation layer. The metal nail sleeve includes a nail sleeve body made of metal, and a fixed disk provided at one end of the nail sleeve body. The fixed disk has a central hole, the nail sleeve body has an axial through hole which is coaxial with the central hole, a guiding element is provided within the axial through hole, the guiding element has an axial hole which is configured to allow a front end of a nail to pass through and to accommodate a nail bar of the nail, the axial hole is coaxial with the axial through hole, the guiding element is made of materials with poor thermal conductivity. Compared with common metal nails, the nail sleeve is thicker, and after the nail sleeve is fit with the nail and combined with the fixed disk, the thermal insulation layer is able to be stably fixed to a wall body. Moreover, the nail sleeve body is a metal cylinder with variable diameter and has a higher strength. By providing the guiding member made of materials with poor thermal conductivity, it is possible to prevent poor heat preservation effects caused by heat exchange between the wall body and the exterior through the nail and the nail sleeve body due to direct contact between the metal nail and the metal nail sleeve body.
