The 22nd episode of Jinnan Safety Classroom – Safety Scaffolding

Firstly, before setting up building scaffolding, determine the installation plan. This includes the treatment of the foundation, requirements for installation, spacing of members, connection methods, and drawing of construction drawings..

Firstly, the foundation of the scaffolding poles should be consistent with the construction plan..

Secondly, the base of the coupler type steel pipe scaffold is made of welded forged cast iron. When erecting, attention should be paid to laying flat wooden pads, placing the base in place, and then erecting the pole. Do not place the upright pole directly on the wooden board..

Thirdly, vertical and horizontal sweeping poles should be installed at a distance of 20 centimeters from the ground without burying them..

Fourthly, when the wooden scaffolding poles are buried, there is no need to set up sweeping poles. When burying up to 30 to 50 centimeters, compact and cushion with broken bricks..

Fifth, when the terrain is low, drainage should be considered. After backfilling, the wooden scaffolding poles should be left with soil piers to prevent water accumulation..

Firstly, when the height of the scaffold is below 7 meters, the method of throwing braces should be set up to stabilize the scaffold. When it exceeds 7 meters, it should be connected to the building..

Secondly, the connecting rod must be connected to the building to ensure its load-bearing capacity..

Firstly, the spacing between large and small horizontal bars should comply with the requirements of regulations and construction plans. When encountering the need to increase the spacing at the entrance, reinforcement treatment should be carried out according to regulations..

Secondly, based on the fact that the upright pole is the main load-bearing member of the scaffold, it cannot increase the spacing, otherwise its load-bearing capacity will be reduced. The stride of the large crossbar cannot be changed..

Thirdly, scissor braces are used to prevent deformation of the scaffold. So it is necessary to set up reasonable diagonal braces to improve their load-bearing capacity and overall stiffness..

Fourthly, diagonal braces should be added to the horizontal diagonal braces to enhance the lateral stiffness of the scaffold..

Firstly, the scaffold board is the platform for construction workers, which must be fully laid according to the width and closely adjacent to the board..

Secondly, the material of the thickened version must meet the requirements, such as bamboo, wood, steel, etc..

Fifth, when encountering work layers, protective railings and toe boards should be installed to prevent falling..
