Description

Technical Field

[0001] This invention relates to the field of building engineering technology, and in particular to a highly adaptable bottom mold. Background Technology

[0002] Prefabricated construction typically involves producing prefabricated components in standardized workshops, followed by assembly and other subsequent processes on the construction site. It offers advantages such as rapid construction speed, minimal on-site work, and a high degree of standardization. Prefabricated concrete components require formwork during production; generally, the formwork is assembled first, followed by the installation of reinforcing mesh and the pouring of concrete. For example, Chinese patent CN201910453445.8 discloses a production method and mold for self-compacting concrete ribbed prestressed composite slabs, including a long-line platform bottom mold, side molds, end molds, and a top mold. The long end of the long-line platform bottom mold is connected to a side mold, and a top mold is set at the upper end of the long-line platform bottom mold. The two ends of the top mold are respectively connected to the corresponding side molds. The short end of the long-line platform bottom mold is connected to an end mold, and the shape of the upper edge of the end mold matches the shape of the side edge of the top mold. The two ends of the end mold are respectively connected to the corresponding side molds to form a cavity with a accommodating space. The end mold has several holes that allow prestressed steel wires to pass through, and anti-leakage plugs are detachably connected to the holes.

[0003] When creating concrete components with decorative lines on the outside, it's not simply a matter of pouring concrete onto a formwork platform; a base mold is needed to shape the lines. However, to enrich the patterns of the lines on the concrete components and enhance the decorative effect, multiple base molds are usually required. Summary of the Invention

[0004] The purpose of this invention is to provide a highly adaptable bottom mold. The bottom mold adopts a modular structure, and when prefabricating concrete components with outer lines, concrete components with different line widths can share the same bottom mold.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a highly adaptable bottom mold, comprising: a bottom mold body, side molds, and a plug. The upper surface of the bottom mold body is provided with a first threaded hole for installing the side molds. The bottom mold body is provided with symmetrically arranged side molds on opposite sides. The upper surface of the side molds is provided with a second threaded hole for installing the side molds. The plug is disposed between the bottom mold body and the side molds. The side of the bottom mold body is provided with a third threaded hole. The side of the side mold is provided with a fourth threaded hole corresponding to the third threaded hole. The side molds are fixedly installed on the bottom mold body by screws. The screws pass through the third threaded hole and the plug in sequence and are then threaded into the fourth threaded hole.

[0006] As a further description of the above technical solution:

[0007] The plug includes a base and a cover plate, with the cover plate detachably mounted on the base and a screw passing through the base.

[0008] As a further description of the above technical solution:

[0009] The base has a movable block that can move up and down. Both ends of the movable block have through holes for screws to pass through. The movable block has a fifth threaded hole inside. The top of the movable block has a rod that passes through the cover plate and connects to the end plate. A spring is fitted on the rod. The cover plate has a groove corresponding to the end plate.

[0010] As a further description of the above technical solution:

[0011] The end plate is detachably mounted on the top of the pole.

[0012] As a further description of the above technical solution:

[0013] The end plate is threaded to the top of the rod.

[0014] As a further description of the above technical solution:

[0015] The end plate is a circular plate.

[0016] As a further description of the above technical solution:

[0017] The side mold has an "L" shaped cross section and includes a first plate and a second plate, with the first plate perpendicular to the second plate.

[0018] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0019] 1. In this invention, the space enclosed by the bottom mold body, the side mold, and the two end caps is used to form lines on the surface of the component. To create lines of different widths and lengths, end caps of different widths and lengths can be flexibly used. The bottom mold adopts a modular structure, allowing concrete components with different line widths to share the same bottom mold when prefabricating concrete components with lines on the outer side.

[0020] 2. In this invention, the screw is threadedly connected to the movable block inside the plug, which can move up and down, improving the connection strength between the plug and the screw and enhancing the overall integrity of the bottom mold. When the plug is not in use, the spring is not compressed, the end plate extends out of the cover plate, and the fifth threaded hole of the movable block is hidden by the base, preventing debris from entering the fifth threaded hole and ensuring the connection effect of the movable block. When installing the plug, pressing the end plate compresses the spring, the end plate is embedded in the groove, the movable block moves downward, and the fifth threaded hole and the through hole are arranged coaxially to achieve the installation of the screw.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0030] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0031] Please see Figure 1-5This invention provides a technical solution: a highly adaptable bottom mold, comprising: a bottom mold body 1, side molds 2, and a plug 3. The upper surface of the bottom mold body 1 is provided with a first threaded hole 11 for mounting the side molds 4. Symmetrically arranged side molds 2 are provided on opposite sides of the bottom mold body 1. The upper surface of the side molds 2 is provided with a second threaded hole 21 for mounting the side molds 4. The plug 3 is disposed between the bottom mold body 1 and the side molds 2.

[0032] The bottom mold body 1 has a third threaded hole on its side, and the side mold 2 has a fourth threaded hole on its side corresponding to the third threaded hole. The side mold 2 is fixedly installed on the bottom mold body 1 by a screw 5. The screw 5 passes through the third threaded hole and the plug 3 in sequence and is then threaded into the fourth threaded hole.

[0033] The plug 3 includes a base 31 and a cover plate 32. The cover plate 32 is detachably mounted on the base 31, specifically by means of countersunk screws or snap-fit. The screw 5 passes through the base 31. A movable block 311, which can move up and down, is provided inside the base 31. Through holes 312 for the screw 5 to pass through are provided at both ends of the movable block 311. A fifth threaded hole 3111 is provided inside the movable block 311. A rod 313 is provided at the top of the movable block 311. The rod 313 passes through the cover plate 32 and connects to an end plate 314. A spring 315 is fitted on the rod 313. The cover plate 32 has a groove 321 corresponding to the end plate 314. The screw 5 is threadedly connected to the movable block 311 inside the plug 3, improving the connection strength between the plug 3 and the screw 5 and enhancing the overall integrity of the bottom mold. When the plug 3 is not in use, the spring 315 is not compressed, the end plate 314 extends out of the cover plate 32, and the fifth threaded hole 3111 of the movable block 311 is hidden by the base 31 to prevent debris from entering the fifth threaded hole 3111 and to ensure the connection effect of the movable block 311. When the plug 3 is installed, the end plate 314 is pressed, the spring 315 is compressed, the end plate 314 is embedded in the groove 321, the movable block 311 moves downward, and the fifth threaded hole 3111 and the through hole 312 are arranged coaxially to realize the installation of the screw 5.

[0034] The end plate 314 is detachably mounted on the top of the rod 313, facilitating the maintenance and replacement of the end plate 314 and the movable block 311.

[0035] The end plate 314 is threaded to the top of the rod 313, which facilitates fine adjustment of the position of the end plate 314 on the rod 313, so that the end plate 314 is fully embedded in the groove 321 after being pressed, thus avoiding affecting the installation of the side mold 4.

[0036] The end plate 314 is a circular plate, which is convenient for operation.

[0037] The side mold 4 has an "L" shaped cross section and includes a first plate 41 and a second plate 42. The first plate 41 is perpendicular to the second plate 42. The first plate 41 is installed on the bottom mold. It should be noted that the width of the first plate 41 of the side mold 4 installed on the side mold 2 is less than or equal to the width of the side mold 2 to avoid affecting the forming of the component lines.

[0038] Working Principle: When fabricating concrete components with external moldings, the main body 1, side molds 2, and end caps 3 are first assembled to form a complete bottom mold. Then, the side molds 4 are installed on the bottom mold using screws. During assembly, a release agent is applied to the surface. Finally, concrete is poured to create the component. The space enclosed by the main body 1, side molds 2, and two end caps 3 is used to shape the moldings on the component's surface. To create moldings of different widths and lengths, end caps 3 of varying widths and lengths can be used flexibly. The bottom mold adopts a modular structure, allowing concrete components with different molding widths to share the same bottom mold when prefabricating concrete components with external moldings. The screws 5 are threadedly connected to the movable blocks 311 inside the end caps 3, which can move up and down, improving the connection strength between the end caps 3 and the screws 5 and enhancing the overall integrity of the bottom mold. When the plug 3 is not in use, the spring 315 is not compressed, the end plate 314 extends out of the cover plate 32, and the fifth threaded hole 3111 of the movable block 311 is hidden by the base 31 to prevent debris from entering the fifth threaded hole 3111 and to ensure the connection effect of the movable block 311. When the plug 3 is installed, the end plate 314 is pressed, the spring 315 is compressed, the end plate 314 is embedded in the groove 321, the movable block 311 moves downward, and the fifth threaded hole 3111 and the through hole 312 are arranged coaxially to realize the installation of the screw 5.

[0039] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
