Description

Technical Field

[0001] The invention relates to the technical field of assembled walls and building energy-saving technologies in the construction field, and in particular to a double-pier-head anchoring device for a metal decorative panel and an anchoring method thereof. Background Art

[0002] Traditional exterior wall insulation is the "post-anchoring and pasting method", that is, first make the exterior wall structure, then fix the insulation layer directly with rivets, and then cover the insulation layer with plaster, commonly known as "thin plastering". The service life of the "thin plastering" insulation technology is 25 years, and it has gradually reached or is approaching its service life. At this time, the performance indicators of the insulation board are basically intact, but some anchoring and bonding systems are no longer suitable for continued work, resulting in wall hollowing. There is a huge stock of such buildings. If the exterior wall insulation system is updated and redone, the project will be huge and will inevitably cause a waste of resources.

[0003] The prior art discloses a local reinforcement device for an external insulation wall with application number CN202122737096.8, which is fixedly connected to the external wall body by a ring bottom. The ring bottom is connected to a flange through a support column, and the diameter of the flange is larger than the outer diameter of the support column.

[0004] However, the solutions in the prior art adopt a positive anchoring method for anchoring during use. This anchoring method has the problem of poor stability, such as poor contact of the anchor rod head and wear of the anchor rod head threads.
