Description
Technical Field
The utility model relates to a scaffold frame and building body connection fixed knot construct.
Background
The external scaffold is a scaffold erected on the periphery of a building, is widely used and is mainly used for building external walls, decorating external facades and reinforcing concrete engineering. The scaffold is installed at the periphery of the building, and in order to keep the structure of the outer scaffold stable, the outer scaffold is required to be fixedly connected with the building. The traditional way is to vertically pre-embed one end of a steel pipe within a structural beam of a building, and then to connect the end of the pre-embedded steel pipe extending out of the structural beam as a fixed point with an external scaffold frame body through a horizontal steel pipe and a fastener. This conventional approach has several drawbacks: (1) the number of the pre-buried steel pipes is large, and the pre-buried steel pipes cannot be recycled after being used, so that great waste is caused. (2) When the subsequent infilled wall is built by laying bricks or stones, the embedded steel pipes extending out of the structural beam need to be cut off, and manual waste is caused. (3) When the embedded steel pipe is cut, the outer wall of a building is basically finished, the working space reserved for cutting the steel pipe is small, the use of a cutting tool is limited, the phenomenon that individual steel pipes are not completely cut exists, a large scaffold hole is reserved on the outer wall, and the hidden quality danger of water seepage of the outer wall exists.
