A high-efficiency sealing device for bolt holes in concrete exterior walls

Abstract

The invention provides a high-efficiency plugging device for bolt holes passing through a concrete outer wall, and relates to the technical field of building construction equipment. The high-efficiency plugging device for the bolt hole of the concrete exterior wall includes a syringe, a filling bag and a puncture needle. The syringe includes an empty cylinder, a piston and a piston handle. One end outside the hollow cylinder is fixedly connected with a piston handle, and the filling bag includes a sealed soft bag and a water stopper, the inside of the sealed soft bag is fixed with foam glue, and the water stopper is fixedly arranged at the rear end of the sealed soft bag . The invention provides a high-efficiency sealing device for the bolt holes of the concrete exterior wall, which can effectively realize the anti-seepage sealing of the bolt holes through the wall, and can complete the two processes of foam glue filling and water stopper filling at one time with high quality. The structure is simple, the cost is low, the syringe can be recycled, the operation is simple during construction, the requirements for operators are low, the application range is wide, and the application prospect is good.

Description

technical field [0001] The invention relates to the technical field of building construction equipment, in particular to a high-efficiency sealing device for bolt holes passing through a concrete exterior wall. Background technique [0002] For construction projects, once there is a problem with the exterior wall, it will inevitably lead to damage to the appearance of the building and affect the beauty of the building. At the same time, water seeps into the interior of the wall, which may not only cause cracks to expand, but also cause concrete carbonation and steel corrosion, thereby endangering the building. The overall stability and safety reduce the service life of the building. For building users, external wall leakage may not only cause certain property losses, such as damage to computers, TVs and other equipment, corrosion of furniture, etc., but may also cause personal injury. Damage, such as water seeping into the wall, contacting the transmission line, resulting in...
