Description

Technical Field

[0001] This utility model relates to the field of building technology, specifically to a keel installation structure. Background Technology

[0002] Traditional methods of installing keel to the wall include the following:

[0003] Method 1 involves connecting the keel to a pre-embedded concrete groove in the building wall. However, this method makes it inconvenient to adjust the installation position of the keel.

[0004] Method two involves anchoring bolts onto the building wall, connecting the bolts to an installation plate, welding a transition plate onto the installation plate, and then welding the transition plate to the keel for fixation. While this method allows anchoring bolts after the building wall is formed, it requires welding. Individual differences in welding skills among workers can lead to inconsistent weld quality, which in turn affects the overall connection quality of the keel.
