　　Iron nails fixed on the wooden square has a lot of knowledge, let's study the stitching methods of iron nails fixed on the wooden square, what are the different places.

　　I. Process principle of plastic formwork project

　　The plastic formwork support system integrates the visual advantages of large steel formwork and the advantages of easy formwork and flexibility of wood formwork. The plastic template can be spliced by fixing iron nails on the wooden square directly. According to the size of concrete members, various models can be used in the vertical and horizontal arbitrary connection combination, convenient construction, through the use of special fixture lock, so that the concrete forming size more accurate. By using plastic formwork, the appearance quality of concrete can be more easily guaranteed, and the construction operation is more convenient than steel formwork, wood formwork and bamboo formwork.

　　Second, low foaming multi-layer plastic building template production process and operation points

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

　　Open mode:

　　1. Control the time of mold removal. Premature removal of molds will lead to wall concrete sticking molds. When the concrete is completely set, the poured concrete will automatically detach from the formwork, making the demodulation process faster and easier.

　　2. The removal of formwork must be ordered by the construction technical department. It is strictly prohibited to remove the formwork without permission.

　　3. The removal of the bottom die shall comply with the provisions of gb50204-2002 Code for acceptance of construction quality of concrete structure engineering. The working team must apply for the removal of the bottom die before the removal is approved by the technical leader of the project department.

　　4, formwork engineering operations should follow the supporting die and mold removal by an operation team, should follow the support to remove the lateral support, then the removal of vertical support and other principles.

　　5. After the plastic template is removed, the working surface is clean, and there is no waste such as ash residue, and there is no need to brush the mold release agent on the contact surface with concrete.

　　Iii. Materials and equipment

　　Materials: low foaming multilayer plastic building formwork, channel steel, Angle steel, wooden square, nails, bolts, rebar, sponge bar.
