If the product has a second curvature of the constant profile (Surface transport), then staggered can be given a corresponding curved shape, resulting in a stamp. One way of forming curved parts is application of large vibroshtampov. This stamp does not slide in form, churning out a product entirely, sealing, and redistributing the weight of concrete, while concrete is transferred to a very significant dynamic impact providing high density product. This method allows you to mold the elements of various shapes and arbitrary, including the variable curvature. In the manufacture of curved products are also used pnevmobeton; fine-grained concrete is served in this case, the pipe under pressure and is applied to form a thin layer through a nozzle, like the shotcrete.

thin curved plate sometimes in order to save floor space and reduce the number of matrices concreted layers on each other, paving the layer between the plates of oiled paper. This method allows us to produce up to five or six items on a single form. Molding can be carried out vibroprofilerom. This method does not allow a fiber heat-treated, practically have to wait for the natural maturation of the elements. processing of thin-walled ribbed plates by usually as follows: the temperature rise to 70-80 C for 3-4 h, isothermal heating – 6 h and cooling – 3 hours stripping products can be carried out after the concrete of 50-70% design strength, but not less than 200 kgssm2. Prestressing valves should be cut in pairs – is symmetrical about the axis of the section.
