As an engineering material with nearly 20 years of history, plastic shuttering panels currently hold a relatively low market share, but they have enormous market potential. Plastic shuttering panels not only effectively reduce the overall cost of construction projects, but old templates can be recycled and reused, which conserves resources and protects the environment.
Furthermore, they have strong plasticity, are lightweight, easy to construct, and easy to demold, which can replace wood templates and reduce the wastage of forest resources. It can be said that plastic shuttering panels are a new type of green building template following steel and wood templates. Let's take a look at the key points to pay attention to when installing and removing plastic shuttering panels.
When installing plastic shuttering panels, ensure the levelness and verticality of the templates. Tools like a level or laser level can be used to ensure the precision of the template's position.
For large areas or high walls, pay attention to reinforcement measures to avoid shifting or deformation of the plastic shuttering panel during concrete pouring. Use structures like beams and vertical supports to ensure the stability of the template.
Avoid prolonged exposure of the templates to high-temperature sources (such as the heat generated during concrete pouring) to prevent deformation of the plastic shuttering panels due to high temperatures.
Special attention must be given to sealing the joints of the plastic shuttering panels to prevent concrete leakage during pouring. Sealants or special sealing tapes can be used at the joints.
During pouring, ensure to vibrate the concrete appropriately to avoid bubbles and voids, and also prevent excessive vibration from deforming the plastic shuttering panels.
After each use, clean the templates promptly, especially the parts that have come into contact with concrete, to avoid hardened concrete residues from affecting future use.
In addition to installing plastic shuttering panels, removing them is also crucial.
The concrete must reach the specified strength before removal, and the building templates should be reasonably dismantled according to technical guidelines.
During removal, follow the principle of removing plastic shuttering panels layer by layer from top to bottom. For example, when removing the first layer of templates, the operator should first remove the handles connected at the top and bottom, then gently tap the top of the template to separate the plastic shuttering panel from the concrete surface of the wall.
During the removal process, it is prohibited to use a crowbar to pry the plastic shuttering panels from the corners of the wall.
Properly place the removed building templates and accessories for future use.
To avoid unnecessary safety accidents, first remove the walings and push-pull props. If necessary, temporary supports can be added. By tapping the top of the template, let the template automatically loosen to separate from the concrete surface.
When dismantling column templates, the best method is to divide the column plastic shuttering panel into two parts, hook them together, and use the hook as a temporary support, finally releasing the hook.
