Description

Technical Field

[0001] This utility model relates to the field of building mold technology, specifically a prefabricated staircase quick assembly and disassembly mold. Background Technology

[0002] Prefabricated construction is a new type of construction method that has been strongly promoted by the construction industry in recent years. This new method breaks down buildings into different components, such as wall panels, floor slabs, beams, balconies, and stairs. After the components are prefabricated in the factory, they are transported to the site for assembly. When processing prefabricated stairs, prefabricated stair quick assembly and disassembly molds are required.

[0003] Most existing molds are integrated and large in size, making it impossible for workers to disassemble them. This necessitates transporting the entire mold as a whole during transport, reducing the convenience of mold transportation. Although some molds can be disassembled, these are mostly disassembled using a large number of bolts and special tools, which reduces the efficiency of mold assembly and disassembly, increases the workload of workers, and reduces the overall practicality and convenience of the mold.

[0004] Compared with the patent application number CN215094395U, this utility model discloses a prefabricated stair component forming mold, including a left mold assembly, a locking assembly, a right sliding mold, an end mold, and a reserved hole mold assembly. This prefabricated stair component forming mold can prefabricate the staircase, enabling rapid construction of the staircase later.

[0005] The above solution can effectively prefabricate stairs, but the mold in the above solution is still an integrated unit. When transporting the mold as a whole, the staff still cannot disassemble the mold for separate transport, which makes the transportation of the mold more laborious. In addition, the mold in the above solution is large in size, which further increases the difficulty of transporting the mold.

[0006] Based on this, we now offer prefabricated staircase quick-assembly and disassembly molds, which can eliminate the drawbacks of existing devices. Utility Model Content

[0007] The purpose of this invention is to provide a quick-assembly and disassembly mold for prefabricated stairs to solve the problems in the background art.

[0008] To achieve the above objectives, this utility model provides the following technical solution: The prefabricated staircase quick-assembly mold includes a left mold, a right mold on one side of the left mold, insert plates symmetrically installed on both sides of the left mold, and positioning frames symmetrically installed on both sides of the right mold. The surfaces of multiple positioning frames are provided with positioning grooves for the insert plates to move. The auxiliary positioning component is set on the surfaces of the left and right molds and is used to position and install the left and right molds together. The fixing components are symmetrically arranged on both sides of the right mold and are used to fix the insert plate and the positioning frame.

[0009] Based on the above technical solutions, this utility model also provides the following optional technical solutions: In one alternative: the auxiliary positioning assembly includes positioning rods and positioning sleeves symmetrically installed on both sides of the left and right molds, and the surfaces of the multiple positioning sleeves are provided with slots for the positioning rods to move.

[0010] In one alternative: the fixing assembly includes connecting rods symmetrically installed on both sides of the right mold, with a limit plate fixedly connected to the other end of each pair of connecting rods, and a sliding plate slidably connected to the outer wall of each pair of connecting rods. A return spring is sleeved on the outside of the connecting rods, and the return spring abuts against the sliding plate and the limit plate. A pull handle is symmetrically installed on one side of the sliding plate, and an installation plate is symmetrically installed on the other side of the sliding plate. The surfaces of the positioning frame and the insert plate are provided with installation grooves for the installation plate to move.

[0011] In one alternative: multiple connecting rods are fitted with accordion covers, and the two ends of the accordion covers are fixedly connected to the opposite side of the slide plate and the limiting plate, respectively.

[0012] In one alternative: the inner walls of both the left and right molds are coated with a nano-hydrophobic coating.

[0013] In one alternative: rubber sealing gaskets are bonded to the contact surfaces of both the left and right molds.

[0014] In one alternative design, the right mold and the left mold are on opposite sides of a stepped shape.

[0015] In one alternative: hanging lugs are symmetrically installed on the upper surfaces of both the left and right molds.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model, through the setting of auxiliary positioning components, facilitates the docking and installation of the left and right molds by the workers, thereby facilitating the casting and production of precast stairs, effectively improving the production efficiency and effect of precast stairs, and improving the accuracy and efficiency of docking between the left and right molds, thus enhancing the overall practicality of the device.

[0017] This invention, through the setting of a fixing component, can effectively connect and fix the insert plate and the positioning frame, thereby enabling efficient connection and installation between the left and right molds without the need for bolts or other tools. This significantly improves the efficiency of disassembling and assembling the left and right molds, reduces the workload of workers, and facilitates the disassembly and separation of the mold as a whole, making it easier for workers to transport the mold in parts. This reduces the difficulty of transporting the mold as a whole and further enhances its practicality and ease of transport. Attached Figure Description

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0023] In one embodiment, such as Figures 1-4 As shown, the prefabricated staircase quick assembly and disassembly mold includes a left mold 1, a right mold 2 on one side of the left mold 1, insert plates 3 symmetrically installed on both sides of the left mold 1, and positioning frames 4 symmetrically installed on both sides of the right mold 2. The surfaces of multiple positioning frames 4 are provided with positioning grooves for the insert plates 3 to move. An auxiliary positioning component is disposed on the surfaces of the left mold 1 and the right mold 2, and is used to position and install the left mold 1 and the right mold 2. The fixing components are symmetrically arranged on both sides of the right mold 2 and are used to fix the insert plate 3 and the positioning frame 4.

[0024] In this embodiment, when the precast staircase needs to be cast, the left mold 1 and the right mold 2 are first positioned and connected using an auxiliary positioning component. After the left mold 1 and the right mold 2 are connected, the insert plate 3 and the positioning frame 4 are fixedly installed using a fixing component. At this time, the left mold 1 and the right mold 2 are fixed, which makes it easier for workers to cast the precast staircase. Moreover, the installation of the left mold 1 and the right mold 2 does not require the use of bolts or other tools, which effectively improves the installation efficiency and effect of the left mold 1 and the right mold 2, reduces the workload of workers, and allows workers to effectively disassemble and separate the mold as a whole, which facilitates the separate transportation of the mold as a whole, effectively reduces the transportation difficulty of the mold as a whole, and improves the overall practicality and transportation convenience of the device. In one embodiment, such as Figures 1-3 As shown, the auxiliary positioning component includes positioning rods 8 and positioning sleeves 7 symmetrically installed on both sides of the left mold 1 and the right mold 2, respectively. The surfaces of the multiple positioning sleeves 7 are provided with slots for the positioning rods 8 to move. When it is necessary to connect and install the left mold 1 and the right mold 2, simply insert the positioning rods 8 into the positioning sleeves 7. At this time, the positioning rods 8 and the positioning sleeves 7 can effectively play a positioning role, which makes it easier for the staff to perform positioning and docking between the left mold 1 and the right mold 2, effectively improving the docking efficiency and effect between the left mold 1 and the right mold 2.

[0025] In one embodiment, such as Figure 3 and Figure 4As shown, the fixing assembly includes connecting rods 10 symmetrically installed on both sides of the right mold 2. A limiting plate 11 is fixedly connected to the other end of each pair of connecting rods 10. A sliding plate 12 is slidably connected to the outer wall of each pair of connecting rods 10. A return spring 13 is sleeved on the outside of the connecting rods 10, and the return spring 13 abuts against the sliding plate 12 and the limiting plate 11. A handle is symmetrically installed on one side of the sliding plate 12, and an mounting plate 14 is symmetrically installed on the other side of the sliding plate 12. The surfaces of the positioning frame 4 and the insert plate 3 are both provided with mounting grooves for the mounting plate 14 to move. When it is necessary to fix the left mold 1 and the right mold 2 together, simply pull the handle first. At this time, the handle will drive the sliding plate 12 to move synchronously on the outer wall of the connecting rods 10. During the movement of the slide plate 12, the return spring 13 is compressed, and the slide plate 12 also drives the mounting plate 14 to move synchronously. At this time, the insert plate 3 is inserted into the positioning frame 4, and then the handle is released. At this time, the return spring 13 is reset, and the slide plate 12 and the mounting plate 14 move synchronously. When the mounting plate 14 is inserted into the mounting groove on the surface of the insert plate 3, the positioning frame 4 and the insert plate 3 can be fixed. At this time, the left mold 1 and the right mold 2 can be fixed, and it is also convenient for the staff to separate the left mold 1 and the right mold 2, so as to facilitate the overall mold to be transported separately. This effectively improves the disassembly and assembly efficiency between the left mold 1 and the right mold 2 and the overall transportation convenience of the mold.

[0026] In one embodiment, such as Figures 1-4 As shown, each of the multiple connecting rods 10 is fitted with a bellows cover 15. The two ends of the bellows cover 15 are fixedly connected to the opposite side of the slide plate 12 and the limiting plate 11, respectively. By setting the bellows cover 15, the return spring 13 can be effectively protected, thereby effectively extending the service life of the return spring 13, without affecting the normal use of the return spring 13.

[0027] In one embodiment, such as Figures 1-3 As shown, the inner walls of both the left mold 1 and the right mold 2 are coated with a nano-hydrophobic coating 5. By setting the nano-hydrophobic coating 5, the probability of cement adhering to the inner walls of the left mold 1 and the right mold 2 can be effectively reduced, thereby effectively improving the overall quality of the prefabricated stairs after production.

[0028] In one embodiment, such as Figures 1-3 As shown, rubber sealing gaskets 6 are bonded to the contact surfaces of the left mold 1 and the right mold 2. When the left mold 1 and the right mold 2 are closed, the rubber sealing gaskets 6 can effectively improve the sealing effect between the left mold 1 and the right mold 2, thereby avoiding leakage of cement after pouring and further improving the production quality of precast stairs.

[0029] In one embodiment, such as Figures 1-3As shown, the right mold 2 and the left mold 1 are stepped on opposite sides. Since the right mold 2 is stepped on one side, after the left mold 1 and the right mold 2 are closed, cement is poured into the gap between the left mold 1 and the right mold 2, which can effectively produce precast stairs.

[0030] In one embodiment, such as Figures 1-3 As shown, the upper surfaces of the left mold 1 and the right mold 2 are symmetrically equipped with hanging lugs 9. By setting the hanging lugs 9, the left mold 1 and the right mold 2 can be effectively lifted and loaded onto the vehicle, which makes it easier for the staff to transport the mold as a whole.

[0031] The above embodiments disclose a quick-assembly and disassembly mold for precast stairs. When the precast stairs need to be poured for production, the left mold 1 and the right mold 2 are first positioned and connected by the cooperation between the positioning rod 8 and the positioning sleeve 7. After the left mold 1 and the right mold 2 are connected, the insert plate 3 and the positioning frame 4 are fixedly installed by the cooperation between the pull handle, the sliding plate 12 and the mounting plate 14. At this time, the left mold 1 and the right mold 2 are fixed, which makes it easier for workers to pour the precast stairs. Moreover, the installation of the left mold 1 and the right mold 2 does not require the use of bolts or other tools, which effectively improves the installation efficiency and effect of the left mold 1 and the right mold 2, reduces the workload of workers, and allows workers to effectively disassemble the mold into parts, which facilitates the transportation of the mold as a whole, effectively reduces the transportation difficulty of the mold as a whole, and improves the overall practicality and transportation convenience of the device.

[0032] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
