Description

Technical Field

[0001] This utility model belongs to the field of building engineering technology, specifically relating to a prefabricated building staircase forming mold. Background Technology

[0002] Precast stairs are popular in prefabricated buildings due to their factory pre-production and rapid on-site assembly, improving construction efficiency and building quality. In today's construction industry, precast stairs are gradually becoming a new trend. These stairs are pre-produced in factories and then transported to the construction site for assembly, greatly improving construction efficiency. Their unique advantages make precast stairs highly regarded in prefabricated buildings and an essential choice for the modern construction industry. As an important component of prefabricated buildings, precast stairs are gradually gaining market favor. Their factory pre-production and rapid on-site assembly not only save construction time but also improve the quality and efficiency of the building. Under the pursuit of green, environmentally friendly, and efficient building concepts, precast stairs have undoubtedly become the preferred solution for the modern construction industry.

[0003] Traditional precast stair molds are mostly one-piece molds, which are difficult to install and disassemble and are prone to damage. If the mold is damaged and deformed, it is difficult to repair, resulting in waste. The molds are large and require a special place to store them, which puts a lot of pressure on the storage management of the construction site or factory. Therefore, a new type of precast stair mold has emerged. Utility Model Content

[0022] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0023] Example

[0024] Reference Figures 1-4 This is an embodiment of the present invention, which provides a prefabricated building staircase forming mold, comprising,

[0025] The system comprises a support plate 101, a bottom mold 102 fixedly installed on the top of the support plate 101, an end mold 103 movably connected to both sides of the bottom mold 102, a first snap-fit ​​groove 104 provided on the outer surface of the end mold 103, a connecting component 105 movably connected to both sides of the first snap-fit ​​groove 104, a pin assembly 106 fixedly installed on the surface of the connecting component 105, and a mating component 107 fixedly installed on the surface of the pin assembly 106.

[0026] Specifically, the connecting component 105 includes a bottom module 105a fixedly installed on the top of the support plate 101, and a step mold 105b movably connected to the top of the bottom module 105a. The connecting component 105 also includes side templates 105c movably connected to both sides of the support plate 101, and a second snap-fit ​​groove 105d and a third snap-fit ​​groove 105e provided on both sides of the side templates 105c.

[0027] Furthermore, the second clamping groove 105d and the third clamping groove 105e are located on both sides of the side template to improve airtightness and prevent slurry from leaking out due to pressure.

[0028] Preferably, the mating assembly 107 includes a protective shell 107a fixedly installed on the top of the pin seat 106a, a socket shell 107b fixedly installed inside the protective shell 107a, a first spring 107c fixedly installed on the inner wall of the socket shell 107b, a first locking tongue 107d sleeved inside the first spring 107c, a fixing block 107e movably connected inside the socket shell 107b, a limiting rod 107f fixedly installed at the bottom of the fixing block 107e, a sliding block 107g slidably connected to the outer wall of the limiting rod 107f, a second spring 107h slidably connected to the limiting rod 107f, and a second locking tongue 107i fixedly installed at the bottom of the limiting rod 107f.

[0029] It should be noted that the first spring 107c is fixedly installed on the inner wall of the sleeve shell 107b, and the first locking tongue 107d is sleeved inside the first spring 107c. When the sleeve shell 107b is pressed, the first locking tongue 107d will push the first spring 107c to extend and retract, thereby achieving the purpose of automatic locking.

[0030] In use, the bottom mold 102 is placed on a horizontal surface. First, the end mold 103 on one side and the side template 105c on the other side are movably installed on top of the bottom mold 102 using a snap-fit ​​method. The end mold 103 and the side template 105c are also movably connected using a snap-fit ​​method. The side templates 105c are then spliced ​​together using snap-fit ​​grooves until a single side mold is formed. Then, the end mold 103 on the other side and the side template 105c on the other side are movably installed on top of the bottom mold 102 using a snap-fit ​​method. Finally, the step mold 105b is movably installed using a snap-fit ​​method. Between the end molds, the mold frame is completed, and the pin assembly 106 and the mating assembly 107 form an automatic spring-back pin lock. Pushing the pin 106b from one side to the other side, the second locking tongue 107i locks the pin hole on the outer wall of the pin 106b, the limit rod moves upward, and the first locking tongue locks the fixing block 107e at the top of the limit rod, completing the locking. Pressing the sleeve shell 107b drives the first locking tongue 107d to move downward, and the first locking tongue 107d moves the sliding block 107g upward to the fixing block 107e and then returns to its original position, completing the unlocking.

[0031] In summary, this makes the precast stair slab mold quick to disassemble; the connecting component 105 and the pin component 106 form a spring-loaded pin, which has a simple structure, is easy to operate, has good control effect, realizes the function of automatic locking, and prevents loosening and displacement during the pouring of precast stairs. It also makes installation and disassembly more convenient, saves manpower and improves work efficiency.
