Box girder internal formwork is an important component of bridge formwork. The following is an introduction to the characteristics of box girder internal formwork.

1, the application of box girder inner mold, pre-made or on-site pouring out of the finished components, can meet the design requirements, and the operation is simple, labor-saving, time-saving, material-saving. Especially in the small cavity to solve the construction difficulties of personnel can not enter the component to remove the mold.

2. The inner mold of box girder has good aging resistance and long service life.

3, box girder internal mold with neoprene rubber, natural rubber and nylon cloth pre-synthesis, after the use of vulcanization process made. It has good anti-expansion strength, elasticity and flexibility, high temperature resistance and good detachment. Fully meet the construction environment under different conditions.

4. The applicable temperature of the box girder inner mold is widely in the range of -10 ℃ ~ 90 ℃, and the material has not changed. It provides favorable conditions for the construction site to reduce the weight of the upper structure of the building, which can shorten the pile foundation and increase the span. Site construction is simple and safe.

5. The construction process of box girder internal formwork is simple, safe and hygienic. When using the airbag internal mold, apply release agent on the outer surface, and carry out leak detection test on the airbag internal mold. If there is no abnormality, pull the airbag internal mold into the reinforcement cage. When the inflation pressure reaches the working pressure, the concrete is poured. When the concrete is initially set, the airbag internal mold is deflated and extracted to complete the molding of the finished component without polluting the environment.
