2. Steel Structure Solutions for LED Display Installation
LED display installation includes assembling steel structures, a complex process with many technical details and wide-ranging requirements.
This guide highlights key principles and best practices for designing efficient hoisting plans, based on experience from multiple steel structure projects.
Accidents and regulatory violations in steel structure installation occasionally occur due to market-related factors. Strengthening on-site management and ensuring compliance with safety standards can prevent unnecessary financial losses and social impacts.
A well-planned approach involves optimizing design, methodologies, and technical measures. Addressing these elements reduces risks and ensures a smoother installation process.
Selecting an innovative, reliable, and cost-efficient construction plan tailored to the project’s requirements is essential. This strategy enhances safety and ensures successful project execution.
2.1 Basic Principles of Steel Structure Hoisting Scheme for LED Display
(1) Policy: based on the drawings and standards, strictly implement the relevant national production safety regulations
(2) Reliability: adhere to safety first, ensure the feasibility of the implementation of the plan, and increase its reliability.
When choosing a method, the first consideration is whether the scheme has a successful precedent and the necessary supporting equipment. If not, the plan must undergo thorough demonstration and validation.
The structural characteristics must be analyzed to ensure stability, and the stress and deformation of components must meet design requirements. Additionally, the mechanical equipment used must align with the installation demands.
It is also essential to evaluate whether the construction site conditions, such as civil engineering constraints or surrounding structures, could hinder the implementation of the plan. These factors must be carefully assessed to ensure feasibility.
(3) Economy: a good installation scheme should be simple in method, appropriate in measure, high in efficiency, low in construction cost, wide in application, and can stand the examination and test.
Therefore, we must adhere to the principle of program comparison, carry out technical and economic analysis, and choose the program with a short duration and low cost.
2.2 5 Common Steel Structure Installation Methods for LED Displays
Because buildings and structures vary so much, there’s no single installation method that fits all LED display steel structure projects.
Each project needs its own tailored solution based on specific site conditions and support requirements.
The commonly used installation methods of grid structure are:
high altitude bulk method, strip and block installation method, structure slip method, support frame slip method, integral hoisting method, integral hoisting method, etc.
(1) According to the process method:
Understand the structure form, structure weight, installation height, span and other characteristics, and try to choose mature and advanced installation technology according to the actual situation on site.
(2) According to the lifting equipment consideration:
For equipment selection, prioritize using your own resources or hiring from nearby providers. In general, truck cranes are preferred when the number of components is limited, while medium or small truck cranes are often chosen for portal rigid frame hoisting.
When the installation period is longer, and the height or turning radius is larger, crawler cranes tend to be more economical than truck cranes. For overall hoisting or sliding operations, hydraulic synchronous lifting (or pushing) devices are commonly used.
For mid to high-rise steel structure installations, tower cranes are typically the most suitable choice. This approach ensures efficiency and cost-effectiveness based on project requirements.
(3) The overall lifting method: computer synchronous control, hydraulic lifting equipment, the process has gradually replaced the heart through mobile lifting and jack jacking scheme, the equipment is light, advanced technology.
Its applicable conditions are as follows:
a. The installation height is relatively high.
b. The components are heavy.
c. It is limited to vertical hoisting and does not support horizontal displacement.
In general, the higher the installation height and the heavier the lifting weight, the more effective this method becomes.
(4) Ordinary hoisting: the earthwork hoisting is the use of single-angle bar, herringbone, rolling machine, pulley block and other lifting equipment for structural hoisting, which is suitable for projects with heavy components, less quantity and higher installation height.
As a result of large tonnage hoisting equipment and advanced installation technology more and more, so the ordinary hoisting is also less and less.
(5) The overall lifting method: it is basically similar to the overall lifting method, but different lifting equipment, suitable for small and medium-sized structure installation. Early use of multiple independent foot bar or herringbone, hoist, pulley block and cable wind system for large tonnage hoisting.
Now, because of the large tonnage of cranes more, according to the needs of small and medium-sized projects to choose a number of cranes to carry out the installation.
