Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1-2, in the embodiment of the utility model, an adjustable prefabricated stair mold comprises a base 1, wherein side plates 2 are arranged on the upper side and the lower side of the base 1, three stair widths are arranged on the surface of the base 1, the stair widths are respectively a3, a b4 and a c5, a plurality of pull rods 6 are arranged on the surface of the base 1 side by side, a plurality of stair railing embedded parts and pin key hole embedded parts 7 are arranged on the surface of the base 1, an upper cover plate 9 and a lower cover plate 9 are arranged at two ends of the base 1, lifting point tool frames 8 are arranged on one side of the base 1 close to the upper cover plate 9 in an array manner, and the stair widths c5 are increased and decreased to meet the size requirements, so that common mode production is realized.

Preferably, the back of the base 1 is provided with a stair a bottom support 11.

Preferably, a plurality of bottom fixing grooves 12 are arranged on the back of the base 1 side by side, and a bottom plate 13 is arranged on the back of the base 1.

Preferably, one side of the side plate 2 is slidably connected with the base 1, and one side of the side plate 2 passing through two sides of the stair mold can slide back and forth, so that the stair width c5 can be taken out or installed.

Preferably, the lifting point tool frame 8 has four total lifting points.

Preferably, the stair width a3 and the stair width b4 are respectively provided with a stair pin key preformed hole in the upper and lower lapping platforms, the stair pin key preformed holes are matched with the pin key hole embedded parts, the number of stair molds can be reduced through common modes of various stair width sizes, and the mold cost is reduced for spreading, so that the stair cost is reduced.
