Description

Technical Field

[0001] The utility model relates to the technical field of stair formworks, and particularly relates to a mold for producing precast stairs of prefabricated buildings. Background Technique

[0002] Precast assembled stairs are a kind of precast concrete components, which are concrete structures formed by assembly, connection and partial in-situ casting. Most of the formworks used for precast stairs are composed of two templates. After the two templates are closed, a stair-shaped mold cavity with an open upper end will be formed between them. Before closing the mold, a release agent needs to be applied to the inner wall of the mold cavity, and the steel bar framework is placed in the mold cavity.

[0003] After retrieval, the prior art with the publication number of CN219294273U discloses a mold for producing precast stairs of prefabricated buildings, including a formwork. A fixed formwork is fixedly connected to the top of the formwork through a cushion block. A second moving formwork and several first moving formworks are slidably connected to the top of the formwork. The first moving formworks are all located between the fixed formwork and the second moving formwork. The outer walls of the fixed formwork and the first moving formworks facing the second moving formwork are both provided with first mold grooves, and the bottom ends of the first mold grooves are fixedly connected with mold bottom plates. This utility model uses a hydraulic cylinder to pull the movable frame towards the fixed formwork, which can drive the second moving formwork and each first moving formwork to move towards the fixed formwork in sequence, so that the adjacent first mold grooves, second mold grooves and mold bottom plates are closed and matched. When demolding, only need to push the movable frame away from the fixed formwork through the hydraulic cylinder, and then use the chain to pull the multiple first moving formworks to be separated one by one, without manual pushing, and the operation is more labor-saving.

[0004] However, although this utility model's precast stair mold reduces manual pushing and is more labor-saving, the mold can only pour and form stairs with a fixed width. The widths required for precast stairs used in different environments will also vary, resulting in a relatively single pouring range for precast stairs. Therefore, a mold for producing precast stairs of prefabricated buildings is proposed to solve the problems raised above. Content of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the utility model provides a mold for producing precast stairs of prefabricated buildings, which has the advantages of adjusting the internal width of the mold for different stairs, etc., and solves the problem that the mold can only pour and form stairs with a fixed width. The widths required for precast stairs used in different environments will also vary, resulting in a relatively single pouring range for precast stairs.

[0006] To achieve the above object, the utility model provides the following technical solution: A mold for producing precast stairs of prefabricated buildings, including a base, and an adjusting device is arranged on the upper side of the base;

[0007] The adjusting device includes a right mold fixedly connected to the upper side of the base at the right end, two threaded rods rotatably sleeved inside the right mold, threaded sleeves threadedly connected to the outer sides of the threaded rods, a moving clamping plate fixedly connected to the left side of the threaded sleeve, and two limiting plates clamped to the upper side of the moving clamping plate.

[0008] Furthermore, a moving device is arranged on the upper side of the base. The moving device includes two vertical plates fixedly connected to the left end of the upper side of the base, a cylinder fixedly installed on the right side of the vertical plate, a left mold fixedly connected to the output end of the cylinder, a staircase groove opened on the right side of the left mold, and a sliding component arranged under the left mold.

[0009] Furthermore, the sliding component includes a plurality of sliders fixedly connected to the lower side of the left mold and a chute opened inside the upper side of the base and adapted to the sliders.

[0010] Furthermore, two clamping grooves adapted to the limiting plates are opened inside the upper side of the moving clamping plate, and an installation groove adapted to the two limiting plates is opened inside the left side of the right mold.

[0011] Furthermore, a turning handle is sleeved on the outer side of the upper side of the threaded rod, and the upper side of the limiting plate penetrates through the right mold and extends to the outside.

[0012] Furthermore, the upper side of the threaded rod penetrates through the right mold and extends to the outside thereof.

[0013] Furthermore, both the installation groove and the clamping groove are trapezoidal groove structures.

[0014] Compared with the prior art, the present utility model provides a mold for producing precast stairs of prefabricated buildings, having the following beneficial effects:

[0015] 1. For the mold for producing precast stairs of prefabricated buildings, by rotating the threaded rod connected by the turning handle to drive the moving clamping plate connected by the threaded sleeve, the vertical height movement of the moving clamping plate in the staircase groove is realized, so as to achieve the adjustment of different widths of the precast stairs.

[0016] 2. For the mold for producing precast stairs of prefabricated buildings, by clamping the limiting plates into the clamping grooves, when the threaded rod drives, the moving clamping plate will also move synchronously in the installation groove, so as to limit the upper side of the moving clamping plate, and solve the problem that the mold can only pour and form stairs with a fixed width, and the widths required for precast stairs used in different environments will vary, resulting in a relatively single pouring range for precast stairs.

The sliding assembly includes a plurality of sliders 5 fixedly connected to the lower side of the left mold 4 and a chute 6 opened on the upper side of the base 1 and adapted to the sliders 5 inside. Two clamping grooves 12 adapted to the limiting plates 10 are opened inside the upper side of the moving clamping plate 9, an installation groove 13 adapted to the two limiting plates 10 is opened inside the left side of the right mold 7, a turning handle 8 is sleeved on the outer side of the upper side of the threaded rod 14, the upper side of the limiting plate 10 penetrates through the right mold 7 and extends to the outside, the upper side of the threaded rod 14 penetrates through the right mold 7 and extends to its outside, and both the installation groove 13 and the clamping groove 12 are trapezoidal groove structures.

[0026] The working principle of the above embodiment is:

[0027] The output end of the cylinder 3 pushes the left mold 4 to move toward the left side of the right mold 7 and conflict with each other. The slider 5 on the lower side of the left mold 4 slides in a limited position in the slide groove 6. The stair groove 11 on one side of the left mold 4 is just engaged with the moving card plate 9.
