Description

Technical field:

[0001] The utility model relates to a prefabricated staircase mould, in particular to an assembled prefabricated staircase mould with adjustable structural dimensions. Background technology:

[0002] Prefabricated stairs are the most mature prefabricated components with simple design theory and no pre-buried water and electricity. In theory, they are very versatile when the floor height is consistent. For example, the patent with application number CN202020984568.2 discloses a prefabricated mold for prefabricated stairs, which can realize the prefabrication of stairs. However, due to differences in architectural design, the prefabricated stairs in different existing prefabricated building projects have different sizes such as stair tread width, step height, and stair section width, which makes the prefabricated mold disclosed in the above patent not universal among various projects and requires redesign and manufacturing of the mold, which increases the design cost and mold cost, and reduces the core competitiveness of the prefabricated stairs. Utility model content:

[0005] Furthermore, a base is provided at the bottom of the stair mold, and a base bracket is fixed below the base.

[0006] Furthermore, a plurality of corresponding reinforcement locking rods are arranged on both sides of the stair mold, wherein the first reinforcement back rib is located between the reinforcement locking rod and the step mold on one side; the top and bottom ends of the two corresponding reinforcement locking rods are respectively connected by a detachable locking structure.

[0007] Furthermore, the detachable locking structure includes a rotatable connecting rod, one end of which is rotatably set on one end of one of the reinforcement locking rods, and a slot is opened at one end of the other reinforcement locking rod. The rotatable connecting rod is movably connected to the slot, and the other end of the rotatable connecting rod is fixed by a nut.

[0008] Furthermore, the rotatable connecting rod located at the bottom end of the reinforcement locking rod is placed below the base.

[0009] Furthermore, a plurality of second reinforcing back ribs are horizontally arranged between the flat bottom back plate and the reinforcing locking rod on the other side.

[0010] Advantages of the utility model: The utility model has a simple structure and is easy to implement. By setting the step mold into a plurality of step outer corner rotatable parts and step inner corner assembly parts that are arranged in sequence, when changing the size, only the step inner corner assembly part, the step bottom assembly part, the step top assembly part, the back panel top assembly part and the back panel bottom assembly part need to be replaced to meet the production of prefabricated stairs with different step heights, widths and number of steps. At the same time, the step outer corner rotatable part is moved along the first reinforced back rib to facilitate the installation of the replaced step inner corner assembly part to ensure the flexibility of the assembly size of the step inner corner assembly and the step outer corner rotatable part, so that the size and number of stair steps can be flexibly adjusted according to the specific project; the versatility of the prefabricated staircase mold is maximized, and the amortization cost of the assembled prefabricated staircase mold is reduced.
