Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a precast concrete slab mold. Background Technology

[0002] In actual construction, there are situations where precast concrete slabs are poured on-site. Concrete is poured into the supported molds on-site, and the molds are removed after the concrete has completely solidified to complete the pouring of the precast concrete slab.

[0003] Chinese patent application number CN201820879259.1 discloses a "simple mold for precast concrete slab". The solution provided by the patent is to assemble / assemble a rectangular container into a precast mold by means of a frame, side templates and bottom template. Reinforced concrete is poured into the container. After the concrete has completely solidified, the frame, side templates and bottom template are removed to complete the precasting of the concrete slab.

[0004] When multiple concrete slabs are used in the same project, leveling of the uncured concrete is required during the prefabrication process to ensure a smooth exposed surface. This typically involves filling the prefabrication mold with concrete and then repeatedly scraping the mold opening with a scraper to level the top surface. However, the prefabrication mold provided in this patent can only be filled with concrete when it is on a relatively horizontal plane. Therefore, this application proposes a concrete slab prefabrication mold that can be leveled even when the mold is not on a horizontal plane, ensuring the mold opening is horizontal. Utility Model Content

[0005] The main purpose of this utility model is to provide a precast concrete slab mold, which aims to solve the technical problem of leveling the precast mold.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A precast concrete slab mold, comprising:

[0008] The support assembly includes two transverse and parallel crossbeams, and a base plate disposed on the two crossbeams.

[0009] The mold assembly, located on the top surface of the base plate, is an upward-facing casting groove;

[0010] The leveling assembly includes several leveling rods fixedly connected to the side of the crossbeam, and a leveling detection element disposed on the top surface of the base plate. Each crossbeam has at least two leveling rods arranged along its axis, and the top of each leveling rod is located below the base plate and connected to the base plate.

[0011] As a further improvement of this utility model, the leveling assembly further includes a sphere, a rotating wheel, and a limiting cylinder. The top end of the leveling rod is connected to a sphere, the bottom end of the leveling rod is coaxially connected to a rotating wheel, the middle section of the leveling rod is a threaded section, and a limiting cylinder is threadedly sleeved thereon. One side of the limiting cylinder is fixedly connected to the side of the crossbeam.

[0012] As a further improvement of this utility model, the bottom surface of the base plate is provided with a limiting groove, the inner wall of the limiting groove is a spherical structure, the radius of the limiting groove is not less than the radius of the sphere, and the sphere engages with the limiting groove.

[0013] As a further improvement of this utility model, the horizontal detection component includes several transparent observation tubes, at least three observation tubes are provided on the top surface of the base plate, the outer wall of the observation tubes is provided with scale lines, the top of each observation tube is open, and the observation tubes are filled with observation liquid.

[0014] As a further improvement of this utility model, the mold assembly includes a first side plate and a second side plate. The two first side plates are parallel to each other and are fixedly connected to the top surface of the bottom plate perpendicularly. The two second side plates are parallel to each other and located between the two first side plates. The bottom edges of the second side plates are all fixedly connected to the top surface of the bottom plate perpendicularly.

[0016] The technical solution provided by this utility model can include the following beneficial effects:

[0017] This invention, through the design of its leveling components—including a leveling rod, a ball, a rotating wheel, and a limiting cylinder—achieves precise leveling adjustments, ensuring the mold's base plate is horizontal and thus improving the accuracy of concrete slab prefabrication. This structure reduces human error during construction and improves the quality of prefabricated slabs. The threaded section of the leveling rod and the limiting cylinder work together to make leveling more convenient and flexible, and can fix the position during adjustment, ensuring the adjusted mold remains stable and horizontal, avoiding positional deviation during adjustment. By setting a transparent observation tube and observation fluid, combined with scale lines, the horizontal status of the mold's base plate can be conveniently monitored in real time. The use of the observation liquid makes the testing process intuitive and easy to operate, avoiding the inconvenience of traditional manual measurement and improving testing accuracy. The mold assembly, through the cooperative design of the first and second side plates, makes the overall structure more stable. At the same time, the vertical fixed connection between the second side plate and the bottom plate enhances the stability of the mold and avoids possible deformation or loosening during the pouring process. The first side plate has an L-shaped structure and is fixed to the bottom plate with bolts. Each side of the second side plate is fixed to other components with bolts, ensuring the overall firmness of the mold and making the assembly and disassembly process more convenient, saving time and labor. The cooperation between the spherical structure of the limiting groove and the sphere enhances the stability of the top of the leveling rod. At the same time, the radius of the limiting groove is greater than or equal to the radius of the sphere, ensuring the fixation and stability of the leveling rod during operation. In summary, this utility model provides a precast concrete slab mold that is easy to level and has a stable structure, which can effectively improve the production quality and efficiency of precast concrete slabs, while also simplifying the operation process and improving the accuracy of operation.

Detailed Implementation

[0024] 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. It should be understood that the described embodiments are merely some, not all, of the embodiments of this utility model. Where there is no conflict, the embodiments and features in the embodiments of this utility model can be combined with each other. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0025] Figure 1 An embodiment of the precast concrete slab mold of this utility model is shown. See [link / reference]. Figure 1 In this embodiment, the precast concrete slab mold includes: a support component 1, a mold component 2, and a leveling component 3.

[0026] Among them, see Figure 1 The support assembly 1 includes two transverse and parallel crossbeams 11 and a base plate 12 mounted on the two crossbeams 11. The mold assembly 2 is located on the top surface of the base plate 12 and is an upward-facing pouring trough. Reinforced concrete is poured into the pouring trough, and the mold assembly 2 is removed after the concrete has completely solidified to complete the prefabrication process of the concrete slab. The leveling assembly 3 includes several leveling rods 31 fixedly connected to the sides of the crossbeams 11 and a level detection element 32 located on the top surface of the base plate 12. The top of each leveling rod 31 is located below the base plate 12. The leveling rod 31 is rotated so that its top lifts the base plate 12, and the level detection element 32 displays the level status of the base plate 12 in real time, thereby accurately adjusting the level status of the pouring trough.

[0027] Specifically, see Figure 2 The adjustment assembly also includes a rotating wheel 33 and a limiting cylinder 34. The bottom end of the leveling rod 31 is coaxially connected to a rotating wheel 33. The middle section of the leveling rod 31 is provided with a threaded section and threadedly fitted with a limiting cylinder 34. One side of the limiting cylinder 34 is fixedly connected to the side of the crossbeam 11. External force drives the rotating wheel 33 to rotate around its own axis, thereby driving the leveling rod 31 to rotate around its own axis. Since the limiting cylinder 34 is fixedly connected to the crossbeam 11, while the leveling rod 31 rotates around its own axis, the top of the leveling rod 31 raises the bottom plate 12.

[0028] Further, see Figure 2The adjustment assembly also includes a ball 35, the top of the leveling rod 31 is connected to the ball 35, and the bottom surface of the base plate 12 is provided with a limiting groove 12a. The ball 35 engages with the limiting groove 12a to support and limit the base plate 12 and prevent the base plate 12 from slipping off the adjustment rod.

[0029] Optionally, the inner wall of the limiting groove 12a is a spherical structure, and the radius of the limiting groove 12a is not less than the radius of the sphere 35, so as to reduce the friction between the base plate 12 and the leveling rod 31 when the base plate 12 is raised.

[0030] Optionally, in this embodiment, it is best to provide two leveling rods 31 on each of the two crossbeams 11. The four leveling rods 31 are symmetrically arranged with the center of the base plate 12 as the center, so that when the base plate 12 is horizontal, the pressure from the base plate 12 borne by each leveling rod 31 is relatively balanced.

[0031] Further, see Figure 3 The level detection component 32 includes a plurality of observation tubes 32a. At least three observation tubes 32a are provided on the top surface of the base plate 12. The top ends of the observation tubes 32a are all open. The observation tubes 32a are filled with observation liquid. The base plate 12 is judged to be in a level state by checking whether the liquid level is parallel to the horizontal plane.

[0032] Optionally, the wall of the observation tube 32a is made of a transparent material to allow viewing of the liquid level.

[0033] Optionally, the wall of the observation tube 32a is provided with scale lines to determine the position of the liquid level.

[0034] Optionally, the observation solution is a colored solution to make the position of the liquid level in the observation tube 32a more obvious.

[0035] Optionally, in this embodiment, four observation tubes 32a are the preferred embodiment. Observation tubes 32a are provided near the four corners of the top surface of the base plate 12 so that the number of leveling rods 31 and observation tubes 32a correspond one-to-one. When the amount of liquid being observed is a fixed value, each leveling rod 31 only needs to be adjusted so that the liquid level in the corresponding observation tube 32a is at the set scale line, thus making the base plate 12 horizontal.

[0036] Specifically, see Figure 3 The mold assembly 2 includes a first side plate 21 and a second side plate 22. The base plate 12 is placed on two crossbeams 11. The two first side plates 21 are parallel to each other and are fixedly connected to the top surface of the base plate 12 perpendicularly. The two second side plates 22 are parallel to each other and are fixedly connected to the two first side plates 21 perpendicularly respectively. The space between the two first side plates 21 and the two second side plates 22 is the casting groove.

[0037] Further, see Figure 3The first side plate 21 has an L-shaped structure and is fixedly connected to the base plate 12 by bolts 23; the bottom edges of the two second side plates 22 are fixedly connected to the base plate 12 by bolts 23, and the two sides of the second side plates 22 are fixedly connected to the two first side plates 21 by bolts 23 respectively, so as to make the connection of the mold stable and easy to remove after the concrete slab is poured.

[0038] In this embodiment, two crossbeams 11 are placed horizontally on the ground, and a base plate 12 is placed on top of the two crossbeams 11. Each limiting groove 12a of the base plate 12 corresponds to the top of each leveling rod 31. The first side plate 21 and the second side plate 22 are connected and fixed to the top surface of the base plate 12 to form a pouring groove on the top surface of the base plate 12. The leveling detection element 32 is used to determine whether the base plate 12 is in a horizontal state, and thus whether the opening of the pouring groove is in a horizontal state. When the opening of the pouring groove is not horizontal, the leveling rod 31 is rotated to raise the base plate 12 to adjust the horizontal state of the pouring groove. When the opening of the pouring groove is in a horizontal state, steel bars are laid in the pouring groove and concrete is poured. When the pouring groove is full of concrete, it is leveled with a scraper or other tools. After the concrete has completely solidified, the mold is removed to complete the pouring process of the concrete slab. By leveling the mold assembly 2, the pouring trough can be filled with concrete, which facilitates the leveling of the top surface of the precast slab and makes the precast concrete slabs more uniform in size.

[0039] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
