Description

Technical Field

[0001] The present application relates to the technical field of concrete moulds, and in particular to a prefabricated concrete component mould. Background Art

[0002] Precast concrete components are widely used in the construction field, and their production efficiency and quality directly affect the progress and cost of engineering projects.

[0003] Traditional molds usually need to be demolded manually or mechanically, which is a cumbersome and time-consuming process. It is also easy to damage components, causing quality problems with the component's appearance, or cause the mold to deform, shortening the mold's service life. Excessive deformation can cause the produced components to fail to meet standard requirements, resulting in component scrapping, which in turn increases production costs.

[0004] The industry is in urgent need of a new type of mold that can simplify the demoulding process, improve production efficiency and reduce component damage. Therefore, the present application provides a mold that can be demoulded without disassembly to solve the above problems. Utility Model Content

[0005] In order to improve demoulding efficiency and reduce component damage, the present application provides a precast concrete component mold.

[0006] The present application provides a precast concrete component mold that adopts the following technical solution:

[0007] A precast concrete component mold comprises an open side mold and a closed side mold fixed on a mold platform, the surface of the mold platform is coated with a release agent, the number of the open side molds is three, two of which are parallel to each other, and the other open side mold is arranged in parallel with the closed side mold, the three open side molds and the closed side molds are assembled to form a rectangular frame, the side surfaces of the open side molds and the closed side molds close to each other are coated with a retarder, each of the open side molds comprises a side plate, the side surfaces of the side plates away from the mold platform are all penetrated with openings for installing protruding steel bars, and the upper surfaces of the open side molds are detachably installed with top plates.

[0008] By adopting the above technical scheme, after the assembly of the open side mold and the closed side mold is completed, the pressure iron applies pressure to them so that the open side mold and the closed side mold are tightly fixed on the mold platform, and the mold release agent is applied on the surface of the mold platform to reduce the adsorption force between the concrete slurry and the mold platform after molding. The retarder is applied on the inner side of the open side mold and the closed side mold to reduce the friction of the side during the lifting process after the concrete is formed. When the concrete component is demoulded, the component is lifted vertically upward through the embedded lifting points on the component. Due to the mold opening design, the protruding steel bars can move upward along the opening without hindrance during the lifting process of the component, and the lifting resistance of the component is small, so that the component can be demoulded smoothly without disassembling the mold, thereby improving the demoulding efficiency and reducing component damage.

[0009] Optionally, there are multiple openings, and the multiple openings are arranged at intervals along the length direction of the side plate, and the shape of the opening is U-shaped.

[0010] By adopting the above technical solution, a plurality of openings are used to insert the protruding steel bars into the concrete member, and when demoulding, the protruding steel bars slide upward through the openings.

[0011] Optionally, mounting plates are fixed to both ends of the side plates, the mounting plates are perpendicular to the side plates and extend toward a side away from the mold platform, both ends of the top plate are fitted with the mounting plates, and a fixing component is provided between each top plate and the mounting plate.

[0012] By adopting the above technical solution, the fixing assembly fixes the top plate on the mounting plate, thereby enhancing the overall strength when the open side mold is used.

[0013] Optionally, the fixing assembly includes a first threaded hole opened at both ends of the top plate, and a second threaded hole is opened on the mounting plate, the first threaded hole is aligned with the second threaded hole, and the first threaded hole and the second threaded hole are threadedly connected with bolts, and nuts are threadedly connected on the bolts, and the nuts and bolts tightly fix the top plate and the mounting plate.

[0014] By adopting the above technical solution, the top plate and the mounting plate are fixedly connected by bolts. When the mold needs to be removed, the top plate can be removed by rotating the bolts and nuts to ensure normal demoulding.

[0015] Optionally, the fixing assembly includes a mounting base fixed on one of the mounting plates, one end of the top plate is rotatably connected to the mounting plate via the mounting base, the rotation axis of the top plate is parallel to the mold platform, the other end of the top plate is plugged into the other mounting plate, an insertion block is fixed to the end of the top plate away from the mounting base, a slot is provided on the other mounting plate, the insertion block is plugged into the slot, a pressure block is also provided on the side of the top plate away from the insertion block, a threaded rod is fixed to the end of the pressure block away from the top plate, and the threaded rod is threadedly mounted on the mounting plate.

[0016] By adopting the above technical solution, the threaded rod is rotated on the mounting plate to adjust the position height of the pressing block. When the pressing block is rotated to the upper side of the top plate, the pressing block presses the top plate against the mounting plate so that the plug block and the slot are tightly inserted and fixed to each other. When the top plate needs to be disassembled, the pressing block is rotated in the direction away from the top plate, so that the top plate can be rotated to make the top plate away from the side plate, thereby facilitating the protruding steel bars to slide upward from the opening.

[0017] Optionally, a limiting plate is fixed on the side of the mounting seat away from the top plate, the limiting plate is vertically fixed on the mounting plate, the limiting plate is made of iron metal, a magnet is fixed on one end of the top plate close to the limiting plate, and when the top plate is in a vertical state, the magnet is attracted and fixed to the limiting plate.

[0018] By adopting the above technical solution, when the component is demoulded, the top plate is in a vertical state, and the limit plate limits the rotation angle of the top plate, and the magnet and the limit plate are automatically attracted and fixed to ensure the stability of the top plate in the vertical state.

[0019] Optionally, the side mold with an opening also includes a bottom plate that increases the contact area between the side plate and the mold platform, the bottom plate is vertically fixed to the side plate, the bottom plate is located on the side away from the top plate, and the side mold with an opening also includes a baffle that enhances the connection strength between the bottom plate and the side plate.

[0020] By adopting the above technical solution, since the opening on the open side mold reduces the overall connection strength, the connection strength between the mounting plate and the base plate is enhanced by arranging the baffle plate.

[0021] Optionally, the baffle is fixed between the side plate and the bottom plate, and the upper edge of the baffle is at the same height as the upper edge of the side plate, and a baffle is fixed between every two openings.

[0024] By adopting the above technical solution, the two baffles are fixed to the edges of the side plates close to the openings, which helps to strengthen the connection strength between the bottom plate and the side plates.

[0025] Optionally, two baffles are fixed between every two openings, and the two baffles are respectively located at the 1 / 4 and 3 / 4 positions of two adjacent openings. A support plate is fixed on the side of the baffle away from the bottom plate, and the length of the support plate is smaller than the distance between the two adjacent openings.

[0026] By adopting the above technical solution, the two baffles are respectively located at the 1 / 4 and 3 / 4 positions of the two adjacent openings, and a support plate is provided, which helps to further strengthen the connection strength of the bottom plate and the side plates.

[0038] The following is combined with Figure 1-6 This application is described in further detail.

[0039] The embodiment of the present application discloses a precast concrete component mold.

[0040] Example 1

[0041] Reference Figure 1 A precast concrete component mold includes a closed side mold 1 and three open side molds 2 fixed on a mold base (not shown in the figure), wherein two of the open side molds 2 are of the same length and parallel to each other, and another open side mold 2 is of the same length and parallel to the closed side mold 1. The ends of the open side mold 2 and the closed side mold 1 are assembled with each other to form a rectangular frame. The inner sides of the open side mold 2 and the closed side mold 1 are used for pouring concrete to form a component. After the open side mold 2 and the closed side mold 1 are installed, a release agent for convenient demoulding is applied to the surface of the mold base, and a retarder is applied to the side surfaces of the open side mold 2 and the closed side mold 1 that are close to each other.

[0042] When the open side formwork 2 and the closed side formwork 1 are assembled, the weight applies pressure to the open side formwork 2 and the closed side formwork 1 to make them stick tightly to the formwork table, and a release agent is applied on the formwork table surface to reduce the adsorption force between the concrete and the formwork table after forming, and a retarder is applied on the inner side of the open side formwork 2 and the closed side formwork 1 to reduce the friction force on the side during the lifting process after the concrete is formed. When the component is demoulded, the component is lifted vertically upward through the embedded lifting points on the component, so that the component can be demoulded smoothly without removing the mold.

[0043] Reference Figure 1 Each side mold 2 with an opening includes a bottom plate 21 and a side plate 22. The side plate 22 is vertically arranged on the mold platform. The bottom plate 21 and the side plate 22 are perpendicular to each other and are L-shaped. The bottom plate 21 extends toward the side away from the side plates 22. The bottom plate 21 increases the contact area between the side plates 22 and the mold platform. The upper surface of each side plate 22 is provided with an opening 221 for installing an extended steel bar (not shown in the figure). The number of the openings 221 is multiple, and the multiple openings 221 are spaced apart along the length direction of the side plate 22. The spacing between the openings 221 is determined according to the spacing of the extended steel bars. The shape of the opening 221 is a U-shaped opening or a trumpet-shaped opening 221 with a widened upper end. The present embodiment is a U-shaped opening, so that the extended steel bar can move up and down through the opening 221.

[0044] A top plate 23 is also detachably mounted on each side panel 22, and the top plate 23 has the same length as the side panel 22. Two mounting plates 24 are fixedly mounted on each side panel 22, and the two mounting plates 24 are located at both ends of the side panel 22. The mounting plates 24 are horizontally arranged, and a fixing component 3 is provided between each top panel 23 and the mounting plate 24. The fixing component 3 detachably mounts the top panel 23 on the mounting plate 24 and the upper side of the side panel 22. When the top panel 23 is located on the upper side of the side panel 22, it helps to enhance the stability of the closed side mold 1 and reduce deformation of the closed side mold 1.

[0045] Reference Figure 1 and Figure 2The fixing assembly 3 includes a first threaded hole 31 opened at both ends of the top plate 23, and each mounting plate 24 is provided with a second threaded hole 32 arranged opposite to the first threaded hole 31. After the first threaded hole 31 is aligned with the second threaded hole 32, the first threaded hole 31 and the second threaded hole 32 are internally threadedly connected with a bolt 33, and a nut 34 is also threadedly connected to the bolt 33. The nut 34 is tightly pressed against the mounting plate 24 to fix the top plate 23 and the mounting plate 24 to each other.

[0046] When the top plate 23 needs to be disassembled, the nut 34 is unscrewed from the bolt 33, and the bolt 33 is moved away from the first threaded hole 31 and the second threaded hole 32 to disassemble the top plate 23, ensuring that the protruding steel bar can slide out from the upper end of the opening 221 when the component is demoulded.

[0047] The implementation principle of Example 1: When the open side mold 2 and the closed side mold 1 are assembled, the iron pressure applies pressure to the open side mold 2 and the closed side mold 1 to make them close to the mold platform, and concrete slurry is poured on the inner side of the open side mold 2 and the closed side mold 1. After the concrete slurry solidifies, the component is demolded. First, the top plate 23 is disassembled, and the component is lifted vertically upward through the embedded lifting points on the component, so that the component can be demolded smoothly without disassembling the mold, thereby improving the demolding efficiency and reducing component damage.

[0048] Example 2

[0049] Reference Figure 3 The difference between this embodiment and the embodiment 1 is that the fixing assembly 3 includes a mounting seat 35, the mounting seat 35 is fixed on one of the mounting plates 24, one end of the top plate 23 is rotatably mounted on the mounting plate 24 through the mounting seat 35, the rotation axis of the top plate 23 is parallel to the mounting plate 24, the other end of the top plate 23 is plugged with the mounting plate 24 on the side of the side plate 22 away from the mounting seat 35, the end of the top plate 23 away from the mounting seat 35 is fixed with an insert block 231, and the mounting plate 24 on the side of the side plate 22 away from the mounting seat 35 is provided with a slot 222, and the insert block 231 is fixed with the mounting plate 24 on the side of the side plate 22 away from the mounting seat 35. 31 is plugged into the slot 222, and a pressing block 36 and a threaded rod 37 are also provided on the mounting plate 24 located on the side of the side plate 22 away from the mounting seat 35. The threaded rod 37 is threadedly installed on the mounting plate 24, and the axis of the threaded rod 37 is perpendicular to the mounting plate 24. The pressing block 36 is vertically fixed on the threaded rod 37, and the pressing block 36 can rotate around the axis of the threaded rod 37. When the top plate 23 is in a horizontal state, the plug block 231 is inserted into the slot 222, and the pressing block 36 is pressed against the side of the top plate 23 away from the plug block 231, so as to fix the top plate 23.

[0050] A limiting plate 38 is also vertically fixed on the mounting plate 24 on which the mounting seat 35 is installed. The limiting plate 38 is made of iron metal and is located on the side of the mounting seat 35 away from the top plate 23. A magnet 232 is fixedly embedded on the side of the top plate 23 close to the limiting plate 38. When the top plate 23 rotates to a vertical state, the limiting plate 38 limits the top plate 23, and the magnet 232 is automatically attracted and fixed to the limiting plate 38, thereby ensuring the stability of the top plate 23 when it is in a vertical state, and no manual support is required for the top plate 23.

[0051] Implementation principle of Example 2:

[0052] The threaded connection between the threaded rod 37 and the mounting plate 24 allows the position height of the pressure block 36 on the threaded rod 37 to be adjusted, and the pressure block 36 is rotatably connected to the threaded rod 37. When the pressure block 36 is no longer needed to press the top plate 23, the pressure block 36 can be rotated in a direction away from the top plate 23, causing the top plate 23 to rotate vertically. When the top plate 23 rotates to a vertical state, the limit plate 38 limits the top plate 23, and there is no need for manual support of the top plate 23, thereby ensuring that the protruding steel bars can slide out vertically in the opening 221.

[0053] Example 3

[0054] Reference Figure 4 The difference between this embodiment and embodiment 1 is that the side mold 2 with an opening also includes a baffle 25. Since the opening 221 opened on the side plate 22 weakens the overall strength of the side mold 2 with an opening to a certain extent, the baffle 25 is provided to enhance the connection strength between the side plate 22 and the bottom plate 21, thereby enhancing the overall strength of the side mold 2 with an opening.

[0055] The baffle 25 is vertically fixed on the bottom plate 21 , and the sides of the baffle 25 are fixedly connected to the bottom plate 21 and the side plate 22 respectively. A baffle 25 is fixed between two adjacent openings 221 , and the baffle 25 is located at 1 / 2 of the two openings 221 .

[0056] Example 4

[0057] Reference Figure 5 The difference between this embodiment and the third embodiment is that two baffles 25 are fixed between two adjacent openings 221 , and the two baffles 25 are respectively located near the edges of the openings 221 .

[0058] Example 5

[0059] Reference Figure 6The difference between this embodiment and embodiment 3 is that two baffles 25 are fixed between two adjacent openings 221, and the two baffles 25 are respectively located at the 1 / 4 and 3 / 4 positions of the two adjacent openings 221, and a support plate 26 is fixed on the side of the two adjacent baffles 25 away from the bottom plate 21. The support plate 26 is horizontally arranged, and the length of the support plate 26 is less than the distance between the two adjacent openings 221, so as to ensure that the protruding steel bars slide out vertically from the openings 221.

[0060] The implementation principle of Examples 3-5 is:

[0061] The baffle plate 25 and the support plate 26 further enhance the overall strength of the side mold with opening 2 to ensure the molding and demoulding of the component.

[0062] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
