This utility model relates to the field of building construction technology. It discloses a joint filler for exterior wall construction, comprising a connecting rod with a joint filling mechanism and a scraping mechanism on its surface. The joint filling mechanism includes an anti-slip block fixed to the surface of the connecting rod. A lower block is fixed to the surface of the connecting rod, with a lower bolt inserted inside. A lower scraper is fitted onto the surface of the lower block. The scraping mechanism includes an upper block fixed to the surface of the connecting rod, with an upper bolt inserted inside. An upper scraper is fitted onto the surface of the upper block. This device, with its anti-slip block and lower block, working in conjunction with the lower bolt and lower scraper, compacts the sealant in the joints during filling, improving the filling effect. Pressing the outer side of the lower scraper onto the joint further pushes the sealant downwards, enhancing the joint filling effect and improving the device's working efficiency.
