Description

Technical Field

[0001] The utility model belongs to the technical field of prefabrication of concrete components, in particular to a bridge deck component mould. Background Art

[0002] The auxiliary components of the railway bridge deck system are an important part of the railway bridge deck system. At present, most of the auxiliary components of the railway bridge deck system are prefabricated by concrete pouring. In the prefabrication process of the auxiliary components of the railway bridge deck system, the structural design of the casting mold plays a vital role in the casting process. During the casting process, the mold needs to be reliably closed and opened, and the auxiliary components need to be demolded after solidifying in the mold. Due to the large volume and weight of the individual auxiliary components of the bridge deck system, and the adhesion between the concrete and the steel mold, demolding is usually difficult. If the demolding process is not well controlled, it is very likely to damage the formed auxiliary components, and it is very easy to cause deformation and damage to the steel mold due to excessive force or uneven force during the demolding process. Therefore, it is of great significance in this field to propose a bridge deck component mold that is convenient and can realize automatic demolding. Summary of the invention
