Stair mold

Abstract

The invention discloses a stair mold. The stair mold comprises a main body, a first supporting seat, a lower supporting plate, a supporting frame, first dovetail seats, an adjusting seat, an adjusting screw rod, a second dovetail seat, a second supporting seat, a fastening bolt and a forming part; the vertical first supporting seat is fixed to the inner wall of the main body; the horizontal lower supporting plate is fixed to the bottom of the main body; the vertical supporting frame is fixed to the bottom end of the lower supporting plate; and two horizontal first dovetail seats are fixed to the inner wall of the body. According to the invention, the adjusting seat is arranged, so that the second supporting seat can be adjusted in the horizontal direction; then the vertical position of the upper forming die body can be adjusted by adjusting the position of an ejecting nut on an ejecting bolt; and meanwhile, the position of a supporting screw rod in a sliding groove is adjusted, and the lower forming die body can be effectively supported, so that stair prefabricated parts of different sizes can be poured, and meanwhile, the lower forming die body can be prevented from being broken.

Description

technical field [0001] The invention relates to the field of construction, in particular to a staircase mold. Background technique [0002] At present, steel molds are used for prefabricated stairs in prefabricated production. Wooden molds are used in very few public construction projects. However, steel molds are expensive and have a long processing and production cycle. There are almost no projects that can be transformed and used simultaneously, while wooden molds The limit of repeated use is 4 times, it is not suitable for steam curing, it is easy to deform, and the surface quality of the finished product is extremely poor. At the same time, the traditional staircase mold needs to use some wood or steel for support during the prefabrication process, and the size of the prefabricated staircase varies. , so that it is difficult to reuse the supporting wood and steel, which easily causes a waste of resources and highlights the shortcomings of traditional staircase molds. ...
