Description

Prefabricated bridge deck system prefabricated die for high-speed railway Technical Field The utility model belongs to the field of concrete pouring molds, and particularly relates to an assembled bridge deck system prefabricated mold for a high-speed railway. Background In recent years, the bridge of high-speed railways in China has larger and larger duty ratio and higher standard, and the auxiliary structure of the bridge deck mainly comprises a protective wall, a vertical wall, a side wall and the like. The prefabricated bridge deck system construction process is characterized in that the prefabricated bridge deck system construction process is molded in a prefabricated field, finished products are transported to a bridge position for installation and positioning, and compared with the traditional in-situ cast-in-situ protective wall and vertical wall process, the prefabricated bridge deck system construction process has the advantages of being free from influence of girder erection period, high in standardized construction degree, more guaranteed in quality safety and the like, and is more suitable for the requirements of civilized construction, rapid construction and unified standardization of the current railway bridge deck engineering. In the prefabrication process of the assembled bridge deck system, the structural design of the pouring die plays a vital role in the pouring process. In the pouring process, the auxiliary bridge deck structure needs to be demolded after being solidified in the mold, and the demolding is generally difficult due to the fact that the size of the single component of the auxiliary bridge deck structure is large and the adhesive force between the concrete and the steel mold is high. If the demolding process is not fully controlled, the formed auxiliary structure is very likely to be damaged, and the deformation and damage of the steel mold are very easy to be caused by overlarge force or uneven stress in the demolding process. Therefore, in the process of manufacturing the bridge deck precast block, the precast block is ensured not to deform in the concrete pouring process, the mold is convenient to disassemble, and the improvement of the molding efficiency is an important point to be solved.
