Description

Technical Field

[0002] In subway stations, pipe corridors and other projects, armpit corners are often set at the intersection of the bottom plate and the side wall. When the middle plate or top plate is being constructed, a full-floor scaffolding is often used as the lower support system of the plate. It is inevitable that some scaffolding poles will be located at the armpit corners. The armpit corners are generally inclined. If the pole base is directly placed on the armpit corners, there will be partial voids at the bottom of the pole, posing a safety hazard. Conventional treatment solutions generally embed steel bars in the armpit corners, and then use concrete triangles or wooden wedges to fill the bottom to provide a flat surface for the pole base; however, the embedded steel bars will destroy the original concrete structure and waterproof integrity, increase many hidden dangers, and also waste materials. In order to solve the above problems, the utility model designs a support base for scaffolding poles at concrete armpit corners. Utility Model Content
