Description

Technical Field

[0001] This utility model relates to the field of prefabricated staircases, specifically to a prefabricated staircase mold. Background Technology

[0002] In the production of prefabricated stairs for prefabricated buildings, specialized molds are typically required for forming. Currently, the most commonly used mold types include horizontal wooden molds and vertical steel molds. While wooden molds have low initial costs and are easy to process, they suffer from drawbacks such as low strength, susceptibility to deformation, limited reuse (usually 8-9 times), difficulty in guaranteeing precision, and poor finished product quality. This not only wastes resources but also increases production costs and construction waste. Steel molds are known for their high strength and durability; however, their massive weight often necessitates the use of heavy lifting equipment such as gantry cranes for installation and dismantling, undoubtedly increasing equipment investment and operational complexity. Furthermore, steel formwork is expensive to customize and lacks versatility. Traditional molds use an integral welded structure, with each mold only suitable for a single staircase size, making it impossible to adjust for different stair parameters.

[0003] Accordingly, this utility model proposes an assembled prefabricated staircase mold. Utility Model Content

[0004] To overcome the shortcomings of the prior art, this utility model provides a prefabricated stair mold. By setting up a step adjustment module, a back plate adjustment module, and an end mold adjustment module, it is possible to prefabricate stairs of different sizes with the same step and tread dimensions, greatly improving versatility. By setting up a back plate standard section, the overall reuse rate of the mold is improved, the amortization cost is reduced, and the expenditure on stair molds is significantly reduced.

[0005] Technical solution

[0006] A prefabricated staircase mold includes a step mold and a back plate mold. Both sides of the step mold and the back plate mold are provided with side end molds. The front end face of the step mold is bolted to a step adjustment module. A first connecting part is fixed on the step adjustment module. The front end face of the back plate mold is bolted to a back plate adjustment module. A second connecting part is fixed on the back plate adjustment module. The first connecting part and the second connecting part are locked at a fixed distance by a long bolt structure.

[0007] Furthermore, the step mold, the back plate mold, and the side end mold are fixedly connected by bolts.

[0008] Furthermore, the backplate adjustment module is also equipped with a demolding fixture.

[0009] Furthermore, the front side of one end of the step adjustment module and the back plate adjustment module is bolted with a step lifting ear mold and a back plate lifting ear mold, respectively.

[0010] Furthermore, the step-shaped ear mold and the back plate ear mold are fixedly connected by bolts.

[0011] Furthermore, an end mold adjustment module is bolted to the front side of the side end mold.

[0012] Furthermore, a standard backplate section for reinforcement is also provided on the upper side of the backplate mold.

[0013] Beneficial effects

[0014] Compared with the prior art, this utility model has the following advantages:

[0015] By setting up step adjustment modules, backplate adjustment modules, and end mold adjustment modules, it is possible to prefabricate stairs with the same step and tread dimensions of different sizes, greatly improving versatility; by setting up backplate standard sections, the overall reuse rate of the mold is improved, amortization costs are reduced, and stair mold expenditures are significantly reduced.

Detailed Implementation

[0028] To better illustrate the content of this utility model, the following description is provided in conjunction with the accompanying drawings and embodiments:

[0029] have Figures 1-10 As shown, this utility model discloses an assembled prefabricated stair mold, including a step mold 1 and a back plate mold 2. Both sides of the step mold 1 and the back plate mold 2 are provided with side end molds 9. The front end face of the step mold 1 is bolted to a step adjustment module 3. A first connecting part 5 is fixed on the step adjustment module 3. The front end face of the back plate mold 2 is bolted to a back plate adjustment module 4. A second connecting part 7 is fixed on the back plate adjustment module 4. The first connecting part 5 and the second connecting part 7 are locked at a fixed distance by a long bolt structure 6.

[0030] Furthermore, the step mold 1, the back plate mold 2, and the side end mold 9 are fixedly connected by bolts.

[0031] Furthermore, the backplate adjustment module 4 is also provided with a demolding fixture 8.

[0032] Furthermore, the front sides of one end of the step adjustment module 3 and the back plate adjustment module 4 are respectively bolted with step lifting ear mold 11 and back plate lifting ear mold 10.

[0033] Furthermore, the step-mounted ear mold 11 and the back plate ear mold 10 are fixedly connected by bolts.

[0034] Furthermore, the front side of the side end mold 9 is bolted with an end mold adjustment module 12.

[0035] Furthermore, a standard backplate section (not shown) for reinforcement is also provided on the upper side of the backplate mold 2.

[0036] Specifically, in use, the step mold 1 and the back plate mold 2 are placed opposite each other. Then, the step adjustment module 3 is bolted to the front of the step mold 1, and the back plate adjustment module 4 is bolted to the front of the back plate mold 2. At this time, the thickness of the pouring space between the step mold 1 and the back plate mold 2 can be locked through the long bolt structure 6, the second connecting part 7, and the first connecting part 5. Adjustment can be achieved when the step mold 1 and the back plate mold 2 are moved.

[0037] Then the side end mold 9 can be installed. If it is necessary to increase the pouring height, i.e. the width of the stairs, the step adjustment module 3 and the back plate adjustment module 4 can be stacked and bolted together. Then the end mold adjustment module 12 of the climbing 2 can be installed on the side end mold 9 to increase the overall height and thus increase the pouring height.
