【 Specification Name 】 “Code for Acceptance of Construction Quality of Concrete Structures” GB50204-2015.
4.1.1 The template engineering should prepare a construction plan. The construction plans for climbing formwork engineering, tool formwork engineering, and tall formwork support engineering should be technically demonstrated in accordance with relevant regulations..
4.1.2 The template and bracket should be designed according to the installation, use, and removal conditions, and should meet the requirements of bearing capacity, stiffness, and overall stability. [The second entry is a strong entry].
4.1.3 The removal of templates and supports shall comply with the provisions of the current national standard “Construction Code for Concrete Structures” GB 50666 and the requirements of the construction plan..
4.2.1 The technical indicators of the materials used for templates and supports shall comply with the current national standards. When entering the site, samples should be taken to inspect the appearance, specifications, and dimensions of the templates and support materials..
Inspection quantity: determined according to the current relevant national standards..
Inspection method: Check the quality certificate document, observe, and measure with a ruler..
4.2.2 The installation quality of cast-in-place concrete structural formwork and brackets should comply with the relevant national standards and construction plan requirements..
Inspection quantity: determined according to the current relevant national standards..
Inspection method: Implement according to the current relevant national standards..
The formwork and support at the post pouring strip should be independently set up..
4.2.4 When installing vertical poles and templates on soil layers, they should comply with the following regulations:.
The soil layer should be solid and flat, and its bearing capacity or density should meet the requirements of the construction plan;.
2. Waterproof and drainage measures should be taken; For frost heave soil, preventive measures should be taken to prevent freezing and thawing;.
Inspection method: observation; Check the soil compaction test report, soil bearing capacity calculation or on-site testing report..
4.2.5 The quality of template installation should comply with the following regulations:.
The contact surface between the template and the concrete should be flat and clean;.
The flooring and membranes used as templates should be flat, clean, and free from sinking, cracks, sanding, or bulging that may affect the quality of the components;.
5 pairs of plain concrete and decorative concrete components should use templates that can achieve the design effect..
