Passive building cold bridge-preventing anchor

Abstract

The invention relates to a passive building cold bridge-preventing anchor. The passive building cold bridge-preventing anchor comprises a metal nail and a shell sleeving the metal nail, wherein the shell comprises a nail cap which can sleeve the tail part of the metal nail and can be detached from the tail part of the metal nail. Through arrangement of the nail cap, which can sleeve the tail part of the metal nail and can be detached from the tail part of the metal nail, on the shell, before mounting of the passive building cold bridge-preventing anchor, the nail cap is detached from the tail part of the metal nail first, and then after mounting of the passive building cold bridge-preventing anchor, the nail cap sleeves the tail part of the metal nail, so that shell destruction is prevented during mounting of the passive building cold bridge-preventing anchor, and energy leakage caused by exposure of the tail part of the metal nail is prevented.

Description

technical field [0001] The invention relates to a passive building anti-cold bridge anchor bolt. Background technique [0002] Plastic anchor bolts are mostly used in the construction process of passive building external insulation. The plastic anchor bolts include metal nails and plastic shells set on the metal nails, and the tails of the metal nails are exposed outside the plastic shell, so that the tails of the metal nails will directly Contact with the concrete base of the exterior wall, causing energy leakage. In order to solve the above problems, a new plastic anchor has appeared. The outer surface of the tail of the metal nail of the plastic anchor is fixed with a plastic shell. However, in the process of installing the anchor and hitting the tail of the anchor, it is easy to damage the anchor. The plastic shell at the tail of the bolt is easy to cause energy leakage. Contents of the invention [0003] The technical problem to be solved by the present invention is...
