Description

Technical Field

[0001] The utility model discloses a staircase mould, in particular to a prefabricated building staircase mould with adjustable steps. Background Art

[0002] Prefabricated building stairs refer to staircase components that are produced and manufactured in factories or other production facilities in advance of the building design. Since they are manufactured in a controlled environment, prefabricated stairs can usually achieve higher precision, and the size and shape are more in line with the design requirements. These staircase components are usually transported to the site and then installed into the building structure by hoisting or other means. Because they are prefabricated staircase components, suitable molds are used during the processing. However, existing prefabricated staircase molds are mostly fixed in specifications and cannot be adjusted according to the number of steps required for the prefabricated building staircase.

[0003] A Chinese patent discloses a vertical building mold that is easy to assemble and splice (authorization announcement number CN216707851U). The patented technology includes a first side panel, a second side panel is attached to one side of the first side panel, a first motor box is welded to the top center point of one side of the first side panel, side baffles are rotatably connected to the two sides of the first side panel via a pin, the top two sides of the second side panel are connected to the second motor box via screws, and the center point of one side of the second side panel is connected to the third motor box via screws. This vertical building mold that is easy to assemble and splice, the connecting pipe and the fixing hole can facilitate the docking of the first side panel and the second side panel, ensure the correct connection between the molds, and make splicing easier. The first rotating rod, the second rotating rod, the third rotating rod and the fourth rotating rod can rotate relative to each other to abut against the side of the first fixed block, making the connection between the templates more stable. The third threaded rod and the second fixed block can facilitate the extension and splicing of the mold, so that a longer vertical building can be cast in one go.

[0004] This patented technology has the advantage of being easy to splice when used, but it still has some shortcomings when used. When the number of steps of the prefabricated building staircase needs to be adjusted, the mold needs to be replaced. The mold of the same specification can only process prefabricated building stairs of one height and cannot be adjusted according to the number of steps required by the prefabricated building staircase. Therefore, those skilled in the art provide a prefabricated building staircase mold with adjustable steps to solve the problems raised in the above background technology. Utility Model Content

[0040] In order to make the purpose, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0041] Example 1

[0042] See also Figure 1-Figure 4 As shown, this embodiment is a prefabricated building staircase mold with adjustable steps, including a base 100,

[0043] The mold 400 comprises an outer fixed mold 401 fixed to the upper end of the base 100, a movable mold 403 located to one side of the outer fixed mold 401, adjustable molds 404 equidistantly spaced between the movable molds 403, inner fixed molds 407 located at both ends of the adjustable mold 404 and respectively located on the inner walls of the movable mold 403 and the outer fixed mold 401, a first closing cover 408 and a second closing cover 409 located to the rear of the adjustable mold 404, an adjustable plate 402 located between the first closing cover 408 and the second closing cover 409, and an adjustable plate 402 also disposed between the outer fixed mold 401 and the movable mold 403.

[0044] The two ends of the adjustment mold 404 are respectively provided with docking blocks 405 and docking grooves 406, and the opposite end of the inner fixed mold 407 is respectively provided with a docking block 405 and a docking groove 406, and the docking block 405 is slidably plugged into the docking groove 406;

[0045] Both ends of the adjustment plate 402 are provided with a clamping block 411 and a clamping slot 410, respectively. The inner wall of the outer fixed mold 401 and the closing cover 1 408 are both provided with a clamping block 411, and the inner wall of the movable mold 403 and the closing cover 2 409 are both provided with a clamping slot 410 that engages with the clamping slot 410.

[0046] Using mold 400;

[0047] The adjustment mold 404 is connected to each other through the docking block 405 and the docking groove 406, and is connected to the inner fixed mold 407 through the docking block 405 and the docking groove 406. The adjustment mold 404 is a mold 400 with a single layer step, and an appropriate number of layers can be installed according to needs.

[0048] It is worth noting that the width of the adjustment plate 402 is consistent with the adjustment mold 404. When the number of the adjustment molds 404 increases, the adjustment molds 404 are increased accordingly, and the adjustment plate 402 is docked with the card slot 410 through the card block 411, and is docked with the outer fixed mold 401 and the movable mold 403 through the card block 411 and the card slot 410, and the closing cover 1 408 is docked with the closing cover 2 409. The upper end of the connected mold 400 is open, and the lower end is fitted with the base 100. Concrete is poured in the space between the closing cover 1 408, the closing cover 2 409 and the adjustment mold 404. The solidified concrete is formed to form a prefabricated building body. This mold 400 can be easily adjusted to meet the needs of different levels of stairs. There is no need to replace the mold 400, which reduces processing costs and makes the mold 400 highly flexible to use.

[0049] Example 2

[0056] Use of the adjustment structure 200 and the mold opening structure 300;

[0057] After the prefabricated building staircase inside the mold 400 is solidified, the motor 201 drives the screw 202 to rotate, and the screw 202 pushes the nut 205, so that the movable mold 403 moves away from the fixed mold, and the space inside one end of the mold 400 is opened. The hydraulic rod 301 drives the stroke plate 302 to move, driving the slidingly installed closing cover 1 408 and the closing cover 2 409 to separate from the outer fixed mold 401 and the movable mold 403. The rear end of the mold 400 is opened, and the clamped adjustment plate 402 moves with it. The prefabricated building staircase inside the mold 400 is opened and taken out, and the adjustment structure 200 plays a role in tightening the mold 400 after it is adjusted. The mold opening structure 300 effectively controls the closing of the rear end of the mold 400.
