[0090] Working principle: The electrical components in this application are all connected to the power supply and control switch when in use. After the present invention is installed, first check the installation and fixation of the present invention and the safety protection, and then it can be used; necessary preparations need to be made before construction. Before erection, the scaffolding pole accessories entering the site must be strictly inspected, and the use of pole accessories with unqualified specifications and quality is prohibited; wear life jackets when working on the dock platform, and each work point is equipped with monitoring and lifebuoys, life ropes, etc. Workers working on the scaffolding wear labor protection shoes and wear safety belts. The safety belts should be hung high and used low. For the convenience of operation and safety, at least three scaffolding boards are laid under the feet, and they are laid steadily. When the scaffolding cannot be laid temporarily for footing or grasping, the gripping rods should be stable frame parts; the free vertical poles located above the vertical pole joints are not used as gripping poles;

[0091] Seasonal construction protection measures: The construction period is the season when typhoons are less frequent in the local area, so typhoon prevention measures need to be taken. During the rainy season, operations should be carried out, mainly to prevent electric shock, lightning, collapse and strong winds. The power cord should use wires other than bare wires and plastic wires, and should not be in contact with the ground. The distribution box should be made of rainproof and waterproof materials, and the electrical layout should comply with regulations. Damaged electrical components should be repaired in time to avoid exposure of live electricity. The metal casing of electromechanical equipment should be grounded or zeroed for protection. When using hand-held power tools and mechanical equipment, qualified leakage protectors should be installed, and lightning protection devices should be installed on scaffoldings that are higher than buildings. In the thunderstorm season, anti-slip measures should be set for on-site scaffolding boards, ramp boards, and work platforms. Anti-slip adjustments should be set on ramp boards to prevent workers from slipping on rainy days. In windy weather, temporary buildings, scaffolding and other windproof safety measures at the construction site should be inspected and reinforced. Before re-construction, check the on-site equipment and facilities, especially special construction equipment and important facilities, and use them only after they are in good condition.

[0092] During construction, scaffolding is built from the ground around the equipment, and scaffolding work platforms are built according to the installation needs on site. The construction process is divided into ground-type scaffolding and suspended scaffolding.

[0093] The erection process of the floor-standing scaffold is as follows: Place the base plate 1 on the ground for installation protection, then determine the position of the passage opening. After determining the position of the passage opening, place the base and the bottom horizontal bar. After moving and fixing the position of the column foot pad 8, erect the columns one by one, and immediately fasten the columns to the bottom horizontal bar for temporary fixation. Then install the small bottom horizontal bar and fasten it to the column or the bottom horizontal bar. Install the first-step small horizontal bar, making the small horizontal bar fasten to each column. Install the first-step large horizontal bar, the second-step small horizontal bar and the second-step large horizontal bar. Then install the diagonal brace and the third and fourth-step small horizontal bars and large horizontal bars, connecting the diagonal brace and the third and fourth-step small horizontal bars and large horizontal bars to the columns. Then erect the cross bracing, lay the scaffold boards and build the ramp; The scaffold passage needs to be fully paved, and railings need to be set on both sides of the passage, with a gap less than 30 mm, and fixed at both ends, with an extension length of 15 - 20 cm;

[0094] The erection process of the suspended scaffold is as follows: Place the I-beam cantilever beam, and successively erect the bottom columns from the foot to both sides. The bottom end of the column is fastened and fixed to the longitudinal bottom horizontal bar. Then install the transverse bottom horizontal bar and fix it to the column. After erecting three to four columns on each side, immediately install the first-step longitudinal horizontal bar and the transverse horizontal bar. The first-step longitudinal horizontal bar is fastened and fixed to the column. Then correct the verticality of the column and the horizontality of the horizontal bar to meet the requirements, and tighten the fastener bolts forcefully to form the starting section of the framework. Then extend and erect forward in turn according to the above requirements until the first erection is completed in a circle; After the circle is completed, comprehensively check the structural quality once, strictly ensure the design requirements and the structural quality, set the connecting wall bars, and erect the second step and the third step according to the procedures and requirements of the first step, and so on. Install the cross bracing in time during the erection process, erect the cross bars between the operation layers, lay the scaffold boards and erect the railings of the operation layer, and fully enclose the toe boards and the dense mesh; The suspended scaffold uses trapezoidal beam clamps and right-angle fasteners to fix the steel beam and the scaffold poles. The erection height of the scaffold platform is about 500 mm below the elevation of the top of the steel beam, the railing height is 1200 mm, and the height of the toe board is 180 mm; One inclined ladder is set for every 30 meters on the pipe gallery scaffold; After the erection of the first layer of the scaffold is completed, start erecting the second layer of the scaffold. The inclined ladder of the second layer of the scaffold is erected into a Z-shaped scaffold on the basis of the inclined ladder of the first layer, and complete the erection work of the above scaffolds in turn;

[0095] When demolishing the scaffold, before demolition, comprehensively inspect the scaffold to be demolished. According to the inspection results, draw up an operation plan. Before carrying out the demolition operation, establish a unified command and conduct technical safety disclosure to the operation personnel: the steps and methods of demolition, safety measures, material stacking location, labor organization arrangement, to ensure the safe and smooth progress of the demolition operation. The demolition sequence layer by layer is: safety net, toe board, safety railing, scaffold board, cross bracing, small horizontal bar, large horizontal bar, vertical pole. Cycle the above sequence. In case of special climates such as strong wind and rain, stop the demolition of the scaffold. It is strictly prohibited to demolish at night.
