Description
Technical Field
The invention belongs to the technical field of building construction, and particularly relates to a scaffold board fixing clamp.
Background
In building construction, especially in the construction of building outer walls, in order to meet construction requirements, a scaffold is usually erected on the building outer wall, and scaffold boards are laid on the scaffold for constructors to walk. Traditional scaffold board is when laying, generally with the both ends of scaffold board set up on two steel pipes of scaffold to tie up scaffold board both ends and steel pipe together with the iron wire, thereby realize the fixed of scaffold board, the condition of "board of picking up" easily appears in the use. Traditional scaffold board adopts iron wire and steel pipe to tie up fixedly when fixed, and the iron wire is tied up the volume greatly, and the operation is complicated, leads to the engineering volume big, extravagant manpower and materials. And the installation and the removal are finished by the binding tool, and the binding tool cannot be reused after the removal, thereby causing great waste. In addition, along with constructor walks on the scaffold board and steps on the increase of number of times to the scaffold board tip, produce the winding at iron wire both ends and can loosen gradually under the effect of pulling force to the iron wire for produce not hard up phenomenon easily between scaffold board and the steel pipe. When people walk to the end part of the scaffold board on the scaffold board after loosening, the whole scaffold board is easy to pry under the action of the weight of a human body, so that constructors slip down, and further safety accidents are caused.
