Embodiment Construction

[0040] The application will be described in further detail below in conjunction with all the accompanying drawings.

[0041] The embodiment of the present application discloses a mold for prefabricating stairs.

[0042] refer to figure 1 , a mold for prefabricated stairs, comprising a horizontal support frame 1, a horizontal bottom plate 2 is installed on the support frame 1, a vertical side mold 3 and a vertical staircase mold 4 are slidably connected to the bottom plate 2, the bottom plate 2, the side The mold 3 and the stair mold 4 cooperate with each other to form a casting cavity 5 , which is in the shape of a prefabricated staircase and communicates with the outside world through the upper end of the casting cavity 5 . The operator pours concrete into the pouring cavity 5, plasticizes the concrete through the shape of the pouring cavity 5, and completes the forming process of the prefabricated staircase.

[0043] refer to figure 1 and figure 2 The end of the bottom ...

Abstract

The invention relates to a precast stair mold and a precast stair machining process. The mold comprises a supporting frame, wherein a bottom plate is arranged on the supporting frame, a side mold bodyand a stair mold body are connected to the bottom plate in a sliding mode, the bottom plate, the side mold body and the stair mold body are matched in an abutting mode to jointly form a pouring cavity, the stair mold body comprises a stair support, the stair support is arranged on the bottom plate and slides, a plurality of adjacent shaping plates are connected to the stair support in a sliding mode, the ends, close to the side mold body, of the shaping plates are in a right-angle shape, movable rods are in threaded connection with the stair support, and one end of each movable rod is rotationally connected with the corresponding shaping plate. When the precast stair is demolded, the shaping plates are sequentially separated from the precast stair, step-by-step demolding is realized, thesituation that stress is uneven during demolding is reduced, the precast stair is easily separated from the stair mold in the demolding process, and the effect of improving the quality of the precaststair is achieved.

Description

technical field [0001] The present application relates to the field of prefabricated concrete components, in particular to a mold for prefabricated stairs and a processing technology for the prefabricated stairs. Background technique [0002] With the development of the construction industry, prefabricated buildings have been widely recognized by people. Prefabricated building refers to the transfer of a large number of on-site operations in the traditional construction method to the factory, where the building components and accessories (such as floor slabs, wall panels, stairs, balconies, etc.) are processed and manufactured in the factory, and transported to the construction site. Reliable connections are assembled and installed on site. Stairs are important components in buildings, and molds for prefabricated stairs need to be used in the production of prefabricated stairs. [0003] Existing publication number is that the Chinese patent of CN106393399A discloses a kind...
