The axial displacement of building formwork often occurs in the construction industry. Here we introduce seven protective measures for the axial displacement of building formwork:
1. In strict accordance with the ratio of 1/10-1/15, turn each sub section and sub item into a detailed drawing, and indicate the number of each part, axis position, geometric dimension, profile shape, reserved holes, embedded parts, etc. After the review is correct, carefully carry out technical disclosure to the production team and operators as the basis for the fabrication and installation of building formwork.
2. After the axis of the building formwork is measured and set out, special personnel shall carry out technical review and acceptance, and the formwork can be erected after confirmation.
3. Reliable limit measures must be set at the root and pre embedded part of wall and column building formwork, such as using short rebar embedded on cast-in-place floor concrete to fix steel support, so as to ensure accurate bottom position.
4. During formwork erection, horizontal and vertical through lines shall be drawn, and vertical perpendicularity control lines shall be set to ensure that the horizontal and vertical positions of building formwork are accurate.
5. According to the characteristics of concrete structure, the construction formwork shall be specially designed door Design to ensure that building formwork and Bracket It has sufficient strength, rigidity and stability.
6. Before concrete pouring, the construction formwork axis, support, top support Bolt Carry out careful inspection and review, and deal with problems found in a timely manner.
7. When pouring concrete, the blanking shall be uniform and symmetrical, and the pouring height shall be strictly controlled within the allowable range of construction specifications.
1. Main technical contents
Plastic formwork is a kind of engineering plastic, which is made of rigid plastics such as poly * * as the base material, reinforced materials such as glass fiber, sisal fiber, and anti-aging additives, through composite lamination and other processes. It can be sawn, nailed, planed, welded, and repaired. Its plate is embedded in a steel frame or nailed to a wood frame. The plastic formwork can be used instead of wood formwork and steel formwork, It is not only environmentally friendly and energy-saving, but also can ensure the quality. The construction operation is simple, saving costs, reducing the labor intensity of workers, reducing the use of steel and wood. This material can be recycled after use.
The plastic formwork has smooth surface, easy demoulding, light weight, good corrosion resistance, more turnover times of formwork, recyclability, less waste of resources, is conducive to environmental protection, and meets the national requirements for energy conservation and environmental protection.
Advantages of bamboo plywood:
1. The surface of bamboo glue formwork is flat and smooth, and its absorption force to concrete is only 1/12 of that of wood plate.
2. Bamboo plywood has high strength and good toughness.
3. Good water resistance and small thermal conductivity.
4. Bamboo plywood has wide width and few butt joints.
5. Many times of use and long service life. The bamboo glue formwork can be used more than 5 times, up to 50 times, and can be used on both sides.
