It's very learned to fix an iron nail on a wooden square

Published:2022-06-16　　

There is a lot of knowledge about fixing iron nails on wooden squares. Let's study the splicing methods of fixing iron nails on wooden squares, and what are the differences.

1、 Process principle of plastic formwork engineering

The plastic formwork support system integrates the visual advantages of large steel formwork and the advantages of easy formwork support and flexibility of wood formwork. The splicing of plastic formwork can directly adopt the splicing method that iron nails are fixed on the wooden square. According to the size of concrete components, various models can be used to connect and combine in any longitudinal and transverse directions, which is convenient for construction. By locking and splicing with special fixtures, the concrete forming size is more accurate. By using plastic formwork, the appearance quality of concrete can be easily guaranteed, and the construction operation is more convenient than steel formwork, wood formwork and bamboo formwork.

2、 Production process and operation points of low foaming multi-layer plastic building formwork

The production process and operation points of low foaming multi-layer plastic building formwork belong to the product patent, and have passed the appraisal of scientific and technological achievements.

Formwork removal:

1. Control the time of formwork removal. Early formwork removal will cause the wall concrete to stick to the formwork. When the concrete is completely solidified, the poured concrete will automatically separate from the formwork, making the demoulding process faster and easier.

2. For formwork removal, there must be a formwork removal order signed by the construction technology department. It is strictly prohibited to remove the formwork without permission.

3. The bottom formwork shall be removed in accordance with the provisions of GB50204-2002 code for acceptance of construction quality of concrete structures. The operation team must apply for formwork removal and remove it after being approved by the technical director of the project department.

4. The formwork work shall follow the principle that the formwork erection and removal shall be carried out by one operation team, and the lateral support shall be removed before the vertical support.

5. After the plastic formwork is removed, the working surface is clean without ash and other garbage, and the contact surface with concrete does not need to be coated with release agent.

3、 Materials and equipment

Material preparation: low foaming multi-layer plastic building formwork, channel steel, angle steel, timber, nails, bolts, steel bars, sponge strips.
