1, formwork and its support shall be designed according to the engineering structure, load, foundation soil type, construction equipment and material supply. Formwork and its supports should have sufficient bearing capacity, rigidity and stability, and can reliably bear the weight, lateral pressure and construction load of pouring concrete;
2. Before pouring concrete, the formwork project shall be accepted. When installing formwork and pouring concrete, observe and maintain formwork and its supports. In case of abnormal situation, it should be handled in time according to the construction technical scheme;
3, template and its support demolition sequence and safety measures should be implemented according to the construction technical scheme. When installing the upper formwork and its support of cast-in-place structure, the lower floor should have the bearing capacity of bearing the upper load, or be supported; The uprights of the upper and lower supports shall be aligned, and cushion blocks shall be laid;
4, cracks, sand or bulging template bulging, for the cast-in-place reinforced concrete beam slab with a span of not less than 4m, the template should be bulging according to the design requirements; When the design has no specific requirements, the springing height should be 1/2 span, and the floor slab should be laid.
Precautions for acceptance of building formwork are as follows:
1. Before formwork construction, the contractor shall submit the formwork design scheme to the supervision engineer, and the construction can be started only after approval;
2, the template and its support must have enough strength, stiffness and stability. Whether the support is firm or not is directly related to the safety problem. We must pay enough attention to it, and its supporting part must also have enough supporting area;
3, template flat-fell seam must be tight, shall not leak slurry, contact with concrete should be clean, and take measures to prevent adhesion;
4. Before pouring concrete, water should be wet. When pouring concrete, a special person should be appointed to "watch the formwork" to ensure that dangerous situations are found and eliminated in time.
"Unified Standard for Engineering Quality Acceptance in People's Republic of China (PRC)" Article 3 The construction quality acceptance of construction projects shall meet the following requirements:
(a) in accordance with the provisions of the engineering survey and design documents;
(two) in accordance with the provisions of this standard and the relevant professional acceptance specifications.
Fifth unit project quality acceptance shall meet the following requirements:
(a) the quality of the project should be qualified;
(two) the quality control data should be complete;
(3) The test data of safety, energy saving, environmental protection and main use functions in subdivisional work shall be complete;
(four) the results of the spot check of the main functions shall comply with the provisions of the relevant professional acceptance specifications;
(five) the visual quality should meet the requirements.
