Ladder scaffold is a common construction equipment.The following will introduce its characteristics,application scenarios,construction points and safety precautions:
Features
Easy to install and disassemble:Ordinary workers can install it in various ways by inserting,sleeve,hanging and other operations without the help of complex tools.Moreover,the weight of a single piece is light,with a maximum of no more than 20 kilograms.It is very convenient to lift,install,disassemble and transport.The installation speed is 1/2 faster than the fastener steel pipe frame and 2/3 faster than the bamboo and wood scaffolding.
Safe and reliable:The overall performance is good,equipped with vertical and horizontal locking devices such as foot pedals,parallel frames,buckle wall pipes,horizontal and cross tie rods,which can effectively enhance the stability of the scaffolding.At the same time,the vertical pipe directly bears the pressure vertically,and the performance indicators meet the construction needs.The main frame and accessories are mostly steel products with good fire resistance.
Multifunctional use:It can be used alone or in pairs,and can be flexibly moved,suitable for a variety of construction scenarios.And the specifications and sizes are standardized,easy to manage and stack,occupying little space,economical and practical,and long service life.
Large bearing capacity:reasonable design,able to withstand large loads,meet the weight requirements of personnel,materials and equipment during construction,good stability,and provide safety for construction.
Application scenarios
Construction:used for supporting the top of the formwork or as the main frame of the flying formwork in buildings,halls,bridges,viaducts,tunnels,etc.,and can also be used as the internal and external scaffolding of high-rise buildings to provide a high-altitude working platform for construction.
Decoration project:In electromechanical installation,hull repair and other decoration projects,it can be used as a movable working platform to facilitate workers to carry out high-altitude decoration work,such as wall decoration,ceiling ceiling,etc.
Temporary facility construction:Using scaffolding with simple roof trusses,temporary construction site dormitories,warehouses or sheds can be constructed.In addition,it can also be used to set up temporary viewing platforms and stands.
Construction points
Foundation treatment:Ensure that the scaffolding is built on a solid and flat ground.For soft or uneven ground,it is necessary to compact,harden or lay wooden boards,steel plates and other measures to ensure the stability of the scaffolding.
Rod connection:According to the design requirements and operating procedures,the various rods of the ladder scaffolding should be correctly connected to ensure a firm connection.If fasteners are used for connection,pay attention to the tightening degree of the fasteners to avoid looseness.
Set support and tie:According to the height and stress of the scaffolding,reasonably set support structures such as scissor braces and transverse supports to enhance the overall stability of the scaffolding.At the same time,it is necessary to reliably tie with the building,such as fixing it to the wall of the building through connectors such as buckle wall pipes.
Ladder installation:The position and angle of the ladder should meet safety requirements,be firmly installed,the step spacing should be uniform,and anti-slip measures should be set,such as laying anti-slip mats or setting anti-slip stripes on the ladder surface.
Safety precautions
Pre-use inspection:Before using the ladder scaffolding,it must be fully inspected to ensure that all rivets,bolts,nuts and moving parts are tightly connected,the ladder columns and steps are firm and reliable,and the extension springs,hinges,etc.are in good working condition.At the same time,check whether the scaffolding is deformed or damaged.Personnel requirements:Operators should be professionally trained,familiar with the use and safety regulations of scaffolding,and in good physical condition.It is forbidden to use ladders when they are tired,taking drugs,drinking or have physical disabilities.
Specifications in use:It is forbidden to exceed the maximum load-bearing mass indicated on the scaffolding during operation.The ladder should be placed on a solid and stable ground.It is forbidden to place it on ice,snow or smooth ground without anti-slip and fixing equipment.When working on the scaffolding,workers should stand firmly to avoid shaking and collisions.It is forbidden to cross directly from one side of the ladder to the other side.
Protective measures:Operators must wear personal protective equipment such as safety helmets and safety belts.The safety belts should be hung high and used low,and fixed in a firm and reliable position.Set up warning signs around the scaffolding to prevent unauthorized personnel from entering the dangerous area.
