After the luminous letters on the roof are produced in the sign factory, it is only one of the links. The installation and construction is the focus of the latter work, and it is also a difficult point, because the installation of the luminous letters on the roof is much more difficult than ordinary the luminous letters on the roof. The roof of the object shines, the conventional elevator may not be able to perform the lifting work. If necessary, it is necessary to use the large boom or tower crane to assist the lifting and installation of the luminous letters on the roof. In order to effectively guarantee the safety of the installation and construction phase of the luminous letters on the roof and smoothly advance the progress of the project, it is usually necessary for both parties to develop a complete set of the luminous letters on the roof installation construction plan in advance. For experienced luminous letters manufacturers, the installation and construction plan is relatively efficient. Because the past project experience is rich enough, it is only necessary to revise the specific dimensions and related data for the specific the luminous letters installation project. The non-data part of the complete solution is basically It can be universal. The following is a reference to the installation experience of the luminous letters on the roof of the past 20 years, and the main points of the plan are attached, and the full text of the plan template.
The main points of the installation plan of the luminous letters on the roof are as follows:
1. Construction safety,civilized construction,eliminate all accidents,Control the security risks at the source and adopt corresponding methods one by one to effectively resolve.Strictly implement relevant standards for sign industry and related processes for aerial work, and civilized construction under the organization and guidance of professional technical engineers.
2. When the luminous letters on the roof, the shell and the bracket should be kept with a protective film on the surface to avoid scratching the surface of the shell due to external factors such as lifting ropes. Save to the last part of the installation and construction, wait for all installations, and remove the protection. Membrane, power supply and other related technical standards test;
3. The sealing and waterproofing work of the light source and the power supply should be in place. Generally speaking, these basic work has been completed in the production workshop of the sign design manufacturer, but some of the luminous letters on the roof are too large. The shell is separated by strokes during transportation, and then assembled on site. In this case, the sealing and waterproofing of the light source and the power source should be paid more attention to. All the components should be assembled according to the assembly plan set at the factory, and the construction scheme must not be changed privately.
The construction difficulty and standard of aerial work are intrinsically different from the factory floor, so the pre-designed installation Construction scheme is more important. In general, the main points of the luminous letters on the roof installation scheme focus on personnel safety, product safety and sealing and waterproofing. In these three aspects, Party A and Party B should also develop and improve the installation scheme of the luminous letters on the roof in advance. The following is a typical model of the luminous letters on the roof installation construction scheme, specific data agreement items. They are all omitted, and they need to be supplemented according to the specific data corresponding to the specific project.
