在建筑工程中，为保证钢筋混凝土构件中混凝土保护层的厚度，必须在钢筋与模板之间绑扎厚薄适当的混凝土垫块。过去均采用现场预制的方式制做这些垫块。造成混凝土构件的保护层薄厚不均，直接影响到工程质量。为解决这一问题，我单位近期研制出生产混凝土垫块的自动成形机似下? In the construction project, in order to ensure the thickness of the concrete protection layer in the reinforced concrete member, a suitable thickness of the concrete pad must be tied between the reinforcement and the formwork. In the past, these blocks were made in a pre-fabricated manner. The uneven thickness of the protective layer of concrete components directly affects the quality of the project. To solve this problem, our company recently developed an automatic forming machine for producing concrete blocks.
