The removal of hollow plastic formwork is a very important part of building construction, which is directly related to the quality and safety of building structures. Therefore, there are some requirements and matters that need special attention when carrying out formwork removal.
First of all, the removal of the hollow plastic formwork must be based on the test data of the retained demoulding test block, and the strength of the concrete must meet the provisions of the specification. This is very important, because if the concrete is not strong enough, the removal of the formwork may lead to deformation or damage to the structure, which will affect the safety and stability of the building. In addition, the formwork at the stress point of the structure must be removed with a formwork removal order, which is to ensure that the demolition is carried out at the right time to avoid unnecessary impact on the structure. The formwork at the post-pouring belt should be dismantled when the concrete of the post-pouring belt is poured and reaches the strength requirements, which is to ensure the quality and stability of the post-pouring belt.
Secondly, the sequence and method of dismantling the plastic building formwork are also very important. It should be carried out in accordance with the provisions of the plate design, following the principle of first supporting and then dismantling, first non-load-bearing parts, then load-bearing parts and top-down. In this way, the stability and safety of the structure can be guaranteed to the greatest extent. When removing the mold, it is strictly forbidden to smash hard pry with a sledgehammer and a crowbar, so as not to cause damage to the template and the structure. Remove the side formwork first, and then remove the load-bearing formwork, which can effectively reduce the deformation and damage of the structure. The removed formwork and accessories should be sorted and stacked neatly, and the accessories should be placed in the toolbox, so that it can be used next time and keep the site clean and safe.
In a word, the removal of hollow plastic formwork is a very important part of building construction, which needs to be operated in strict accordance with the regulations and requirements to ensure the quality and safety of the building structure. Only in this way can we ensure the smooth progress of the construction project and the final quality standard.
