This invention relates to the field of building technology, specifically to a prefabricated liquefied gas cylinder storage facility. The facility includes a storage body, which is assembled from multiple sets of prefabricated wall panels (Part 1 and Part 2). The prefabricated wall panel includes: a first assembly located on one side of Part 2, with a connecting piece on its outer side; a second assembly located on its outer side, with a connecting groove on its inner side; the connecting piece is used to pre-fix Part 1 and Part 2; and a moving part located inside Part 1, with a movable part inside and a positioning part fixedly connected to its outer side. The positioning part is used to fix Part 1 and Part 2. This invention, through the positioning part and positioning groove within the prefabricated liquefied gas cylinder storage facility, facilitates the fixing of Part 1 and Part 2, thus eliminating the need for screws during assembly.
