Here you will get a comprehensive overview of sandwich panel construction in a clean area. For sandwich panel construction, the most important thing is that there must be no water in the construction environment.
Preparation before sandwich panel construction:
You should develop a specific secondary drawing based on the provided design plan, which includes layout and plan for roofing panels, ceiling panels and wall panels. Sandwich panel specification must be correct before ordering.
Choose a suitable type of sandwich panel for a specific project.
Clean the air ducts and work area within the designated clean area thoroughly, remove any unnecessary materials that could hinder the construction.
Insulated panels require careful handling to prevent surface damage during transportation. This requires a protective film on the sandwich panel surface, proper packing way, and correct loading and unloading actions.
Store the color coated sandwich panel and aluminum accessories in a dry, clean, flat and stable location. The insulation panels shall be stacked in a uniform manner, and the stacking height shall not exceed 2.0 m.
Inspect the sandwich panels for any scratches or damage once they arrive the project site. Strictly check the panels geometric dimensions and specification to comply with the designed drawings and project requirements.
The installation of the insulated sandwich panel shall be carried out after the basic completion of the building decoration works and the completion of the main part of the ventilation, power electricity and process supervisor.
Under sandwich panel construction:
During sandwich panel installation, avoid removing the plastic protective film from the sandwich panels surface. Do not hit or step on the insulated panels.
Use silica glue to seal all installation gaps between the panels, panels and accessories. Clean the gaps carefully to remove impurities and oil stains. Ensure a dense, consistent seal to prevent material detachment and dust accumulation. The finished silica glue surface should be smooth without wrinkle.
the site shall be cleaned after the completion of construction every day to ensure that the materials and site are clean after the completion of work every day.
In the process of installation, machinery such as cutting machine, installation accessories and construction site shall be cleaned and cleaned at any time.
You should know clearly the labor division and cooperation. Make a equal labor intensity and orderly cooperation. In addition, some people are also required to clean up the construction site, tidy up the odds and ends, and help wherever needed.
This is because in the construction site, for example, when you are fixing the ground channel, it needs to drill holes with electric hammer, which it is easy to produce dust. If this dust not cleaned in time, the whole ground and aluminum profiles will be covered with dust due to the movement of personnel in the construction process.
Also, when you cutting the aluminum profiles, sharp-angle debris can easily stick to its feet if it is not cleaned in time, which will cause potential safety hazards.
If the cut pieces are not classified and stacked in time, it is easy to scratch the sandwich panels. So it is very necessary to make reasonable arrangements for manpower.
You should know clearly the sequence of installation. Install the wall panels first and then the top ceiling panels.
Wall Panel Installation:
Install the insulated panel partition according to the layout plan with the error less than 1.5 ‰. The wall corner shall be connected vertically, with diagonal error less than 1 ‰.
According to the setting out datum, the ground floor shall be cleaned to ensure that there is no dust on both sides of the ground channel. The aluminum alloy U channel shall be fixed on the ground with shooting nails at an interval of 0.5 m, the ground channel and the ground shall be closely connected.
The perpendicularity of the insulated wall panel installation shall be corrected with the magnetic line of force, and the deviation shall not be greater than 1 ‰. In order to prevent the wall panel from tilting and twisting caused by accumulated error, the gap between the wall panels shall be strictly controlled within 2.5 mm. Maintain consistent gaps throughout the installation, both vertically and horizontally.
Do the cleaning job before installing the internal arc alum. at the connection angle between wall and ceiling. Seal the angle with building sealant. The internal arc base is fixed with the wall panel and ceiling panel by aluminum rivets first, then cover the internal arc alum. closely to the panels without any wavy gaps.
The switch socket openings can be open in sandwich panel factory during production or open on construction site. If open in factory, then you need to provide a drawing for the opening size and position. If open on site, you need to cooperate and work closely with the electrician.
Ceiling Panel Installation:
(1) During the installation, the connection and fixation position of the three-dimensional components such as the hanging and anchor parts that need to hang the girder and strengthen the lifting points and the roof beam shall be determined according to the layout of the secondary design.
The details are as follows:
the spacing of the hanging bars shall be arranged every 1.2 m in the vertical and horizontal layout.
the roof beam is fixed with φ 10 mm inner wire expansion screw.
the other end of the suspender is connected with the galvanized turnbuckle and the T alum. or concealed girder, so as to adjust the flatness of the ceiling.
(2) The ceiling panel shall be installed according to the direction of the room, and the gap shall be kept within 2-3 mm between the ceiling panels for the concealed ceiling girder connection with rivets every 0.5 m to make the connection firm.
(3) When the length of the ceiling panel is more than 3 m, in addition to hoisting the concealed girder in the width direction, the length direction shall be strengthened. The special C-shaped steel or L-shaped steel reinforced girder shall be used to reinforce together with another suspender to lift up.
(4) After the construction of ceiling panel is completed, protection measures shall be taken for the construction of other jobs on the ceiling, and large-scale processing and manufacturing on the ceiling are strictly prohibited.
Insulated Panel Maintenance:
If insulated sandwich panel is scratched and installed, it may lack of beauty, which may have a corresponding impact on the continuous use of the insulation panel, especially in some acid-base and salt fog environments.
Therefore, when you encounter such a problem, you first need to solve such a problem. Then how can you do the insulation panel maintenance? That is to repair the scratched insulated panel.
Generally, if the scratched area of the sandwich panel is not large, the cloth wheel can be used for light polishing and then coated with anti-rust oil for storage, and then a subsequent coating process can be carried out.
In addition, oil removal is also required for the coating of the insulation panels. If the rust spot of insulation panel is deep and the injured area is large, then you must first carry out relevant treatment on its surface, and then carry out relevant repair.
It can be wiped clean and bright with alcohol, and finally with a soft cleaning ball, which can be very clean.
Specific installation procedures may vary depending on the project requirements and the chosen insulated panel system. It's crucial to consult the manufacturer's recommendations and relevant building codes for detailed instructions.
Always prioritize safety throughout the construction process. Workers should wear appropriate personal protective equipment (PPE) and adhere to established safety protocols.
By following the above guidelines and focus on cleanliness throughout the process, you will ensure a successful and high-quality insulated sandwich panel construction project.
