[0032] Referring to the accompanying drawings, the prefabricated concrete staircase mold includes a detachably connected backboard template 4 and a step surface template 5; the mold forms a cavity 9 for pouring precast concrete stairs through the combination of the backboard template and the step surface template, and travels along the stairs One side of the direction forms an opening 10 for pouring concrete;
[0033] The mold also includes a support base 1, the combined back plate formwork and step surface formwork are rotatably connected on the support base 1, the mold has a horizontal state on the support base and a vertical state with the opening facing upwards after being turned around the rotating joint .
[0034] Wherein, as shown in the figure, the inner wall surface of the step surface template is a step surface structure forming a stair step.
[0035] During specific implementation, the mold also...
Embodiment 2
[0039] A kind of method utilizing embodiment 1 mold to manufacture stairs, the method steps are as follows:
[0040] A. Place the reinforced mesh cage of the prefabricated concrete stairs on the backboard template; Figure 4a shown.
[0041] B. Install the combined step surface template; Figure 4b shown.
[0042] C. Turn the combined backboard formwork and step surface formwork into a vertical state on the support base through the overturn mechanism; as Figure 4c shown.
[0043] D. Pouring concrete from the side opening of the mold; Figure 4d shown.
[0044] E. After the precast concrete stairs are formed and meet the strength requirements, turn the combined back plate formwork and step surface formwork into a horizontal state on the supporting base through the overturning mechanism; Figure 4e , as shown in 4f.
[0045] F. Remove the step surface template of the mold; Figure 4g shown.
[0046] G. Take out the precast concrete stairs.

Abstract
The invention discloses a prefabricated type concrete stair mould and a stair manufacturing method. The mould comprises a back board molding board and a step surface molding board which are detachably connected; the molding boards are combined into a cavity for pouring prefabricated concrete stairs, and are equipped with side openings for pouring concrete; the mould further comprisesa supporting base; the molding boards are rotatably connected on the supporting base; and each molding board has a horizontal state and a perpendicular state for forming an upward opening after being turned over around a rotary connecting part. The manufacturing method comprises the following steps of: suspending a reinforcing mesh cage, assembling a step surface molding board, turning the mould into a perpendicular state, pouring concrete, turning the mould into a horizontal state, disassembling the step surface molding board and the like. According to the mould and a construction method thereof, prefabricated concrete stairs do not needed to be turned over while the horizontal type stair mould is disassembled, damages caused by product turning over are avoided, most important features and least light receiving surface requirements of vertical type stairs are met, forming appearance is good, and product quality is guaranteed.
Description
Technical field: [0001] The invention relates to the prefabricated and assembled building industry, and relates to a novel prefabricated and assembled concrete staircase mold and a construction and manufacturing method for the staircase. Background technique: [0002] Housing industrialization, emphasizing the manufacture of housing by large-scale industrial production methods to improve production efficiency and overall quality, has become the mainstream of the current development of the international housing construction industry. Prefabricated concrete technology can shorten the construction period, reduce costs, ensure building quality, save energy and resources, and reduce the adverse impact of construction waste on the environment through factory prefabrication and on-site assembly. The development of prefabricated structural systems is the only way for residential industrialization. The design and construction methods of building molds are the basis of housing industr...
