how to make the new type of door-type buckle scaffold more stable?

high formwork with a height of 4.5m or more shall be prepared by the construction unit before construction. The technical party shall include the design, erection and demolition of the formwork and its branches, concrete pouring methods, pouring process observation and control requirements, etc. No construction shall be carried out without technical plans.

In addition, the lightness of the new type of disc-type scaffolding product makes it easy to disassemble and assemble, which also reduces the labor intensity of construction workers. The design of the new type of disc-type scaffolding tends to be light, and the internal and external source dynamic steel pipes are selected. The amount of steel consumables in the production link is more than 40% saved than the traditional steel pipe scaffolding. Therefore, in the construction of disassembly and assembly to reduce the labor intensity of workers, so that they are not so tired in the operation, the mental state is relatively good, the safety factor naturally rises.

the new portal scaffold is installed with its own scale, it should be uniform, and there should be a constant support system for the purpose of the two targets perpendicular to each other. Before erection, it should be strictly set out in the field according to the design requirements. When installing the portal frame support, it is required to add a 48*3.5 steel pipe degree pull rod to buckle it for each layer of portal frame installed. Vertical and vertical hinged shear braces are inserted at a spacing of less than 6m. The support force of the new type of portal steel pipe scaffold mainly depends on the overall force of the support frame. To reflect this overall effect, it is necessary to "bind" each portal frame by means of vertical and horizontal degree tie rods and vertical hinge shear braces. If you do not set the vertical and horizontal degree tie rod and vertical hinge shear brace, it is as easy to break as chopsticks, and the gantry support is easy to collapse. This requires that the extension length of the adjusting bolt of the adjustable bracket (base) should not be greater than 200mm. When the extension length of the bolt of the adjustable bracket (including the base) is greater than 200mm, the fixing method of adding a degree tie rod can be adopted. Many operators do not understand this point, screw out the bolts for a long time, and do not adopt methods to reinforce them, which greatly reduces the force of the gantry and often leads to collapse accidents.

connection construction, the tightening torque of all kinds of connecting fasteners bolts of the gantry is between 40-65N-m to prevent the components from effectively bearing or being crushed. After erection is completed, a wrench is used for random sampling inspection. Those who fail must be tightened from the beginning until they pass. It is not allowed to lack connecting members or bolts to be tightened or disassembled at will after installation, which will deform the new portal scaffold and be crushed. The supporting pole should be vertical and the vertical and horizontal degree pole should be flat. The vertical rod shall be made of through-length steel pipe as far as possible. If it needs to be connected, the joints shall be staggered and not within the same step distance. The vertical rod openings shall be docked according to the specifications to ensure the verticality of the frame body. The joints of two adjacent longitudinal degree rods shall be interwoven with each other, and the connection ports shall be docked according to the specifications.
