Sealed connection structure of aluminum alloy window frame
ActiveCN105804618BImprove water tightnessImprove air tightnessFrame fasteningCondensed water formation preventionAir tightnessFastener
An aluminum alloy window frame sealing connection structure solves the problem of rainwater leakage caused by insufficient filling of the gap between the aluminum alloy window frame and the opening wall. It includes an aluminum alloy window frame and a stone panel fixed on the wall of the hole. The frame and the hole wall are sealed and connected with a waterproof rubber plate. After one end of the waterproof rubber plate is connected and fixed with the aluminum alloy window frame frame by stainless steel screws, it is sealed with the stone panel by a sealing material. The other end of the waterproof rubber plate is connected to the hole. The wall is connected and fixed by nailing, the gap between the bottom of the waterproof rubber plate and the wall of the hole is sealed with sealant, and the gap between the waterproof rubber plate and the steel sub-frame is filled with thermal insulation material. Its structural design is reasonable to ensure that the gap is filled full and dense without cracks, and the sealing connection is reliable, which can effectively prevent rainwater leakage and improve the airtightness and thermal insulation performance of aluminum alloy windows.

The invention discloses a multilayer inspection well and a manufacturing method thereof. The inspection well comprises multiple layers of well shafts, multiple layers of well bases, and a well lid, wherein the well base in each layer comprises a cylindrical base part, well shaft connectors which extend from the upper and lower ends of the base part, and at least one transversely formed pipeline connector; at least one ends of the well shafts are in fusion welding with the well shaft connectors in a thermoplastic manner; and the upper end of the well shaft in the topmost layer is connected with the well lid. When the multilayer inspection well is utilized, pipelines which are embedded in different underground vertical positions and have various different functions can be monitored at the same time in one inspection well; the well shafts and the well bases are in sealed connection, so that the inspection well is more stable; and when the well shafts and the well bases are connected and when the ground subsides due to overload or underground tunnels subside due to various reasons, the well shafts of the inspection well can have certain elastic deformation due to the fact that the well shafts have certain elasticity, so that connection of the pipeline connectors of the inspection well and the original pipelines remains stable, sealing performance is good, and the inspection well is not liable to damage.
