Technical Field

[0001] The utility model relates to the technical field of antique concrete slab production, in particular to a die assembly for a spliced antique concrete slab. Background Art

[0002] Antique concrete slabs are materials widely used in architectural design and construction. They are characterized by imitating traditional building materials such as stone and wood in appearance and texture, but are actually made of concrete, with advantages such as realistic appearance, strong durability, convenient construction, and high cost-effectiveness. Therefore, they are widely used in various antique buildings and landscape projects.

[0003] When producing antique concrete slabs, concrete raw materials are poured into a mold and vibrated and compacted to ensure that the concrete fills the mold and reaches the required density. To enhance the structural strength of the antique concrete slabs, a steel bar grid is usually placed in the mold cavity before pouring, so that the cured concrete is integrally connected with the steel bar grid. In the prior art, a support groove is usually opened on the side wall of the mold. After the steel bars on the steel bar grid are placed at the bottom of the groove, the upper part of the support groove is sealed. The antique concrete slabs produced by using the above mold, although the structural strength is enhanced by the steel bar grid, the steel bars protrude from the surface of the concrete slab, making it difficult to splice and assemble the concrete slabs; and during the pouring process, the concrete slurry easily enters the part where the steel bars penetrate the side wall of the mold, and the concrete slurry in this part solidifies to connect the steel bars with the mold, making it difficult to demold.

[0004] Therefore, it is necessary to improve the production mold of the antique concrete slabs in the prior art. Content of the Utility Model

[0037] The following combines the drawings and embodiments to further describe the specific embodiments of the present utility model. The following embodiments are only used to more clearly illustrate the technical solutions of the present utility model and cannot be used to limit the protection scope of the present utility model.

[0038] As Figures 1 - 10 shown, the die assembly of the spliced antique-style concrete slab includes:

[0039] The bottom die assembly 1, the bottom die assembly 1 includes a casting table 11 with a horizontal top surface;

[0040] The side flat die assembly 2, the side flat die assembly 2 includes side flat die bars 21 extending in the horizontal direction, and there are two side flat die assemblies 2 arranged opposite to each other in the horizontal direction;

[0041] The concave-convex side die assembly 3, there are two concave-convex side die assemblies 3, the two concave-convex side die assemblies 3 are the opposite side concave die assembly 31 and side convex die assembly 32, both the side concave die assembly 31 and the side convex die assembly 32 extend in the horizontal direction perpendicular to the length direction of the side flat die bar 21, and the opposite surfaces are respectively provided with mutually adapted and opposite grooves 311 and ridges 321, and both the grooves 311 and the ridges 321 extend in the horizontal direction perpendicular to the length direction of the side flat die bar 21;

[0042] The driving assembly 4, the driving assembly 4 is used to drive the side convex die assembly 32, the side concave die assembly 31, the two side flat die assemblies 2 and the bottom die assembly 1 to close and open the mold;

[0043] The supporting assembly 5, there are two supporting assemblies 5 and they correspond to the two concave-convex side die assemblies 3 respectively. Each supporting assembly 5 includes a supporting bar 51 extending along the length direction of the ridge 321 and having a gap with the top surface of the casting table 11. The supporting bar 51 is detachably connected to the corresponding concave-convex side die assembly 3, and the supporting bars 51 of the two supporting assemblies 5 cooperate with each other to support the steel bar grid 6.

[0044] When the device is in use, first, the supporting bar 51 is installed on the opposite surfaces of the side concave die assembly 31 and the side convex die assembly 32. The supporting bar 51 is detachably connected to the corresponding concave-convex side die assembly 3. Then, through the driving assembly 4, the mold is closed, so that the two side flat die assemblies 2 and the two concave-convex side die assemblies 3 approach each other, and are connected end to end in sequence and enclose a casting cavity with the casting table 11.

[0045] The two supporting bars 51 are located in the casting cavity. It is convenient to place the steel bar grid 6 through the two supporting bars 51. The steel bar grid 6 includes first steel bars 61 arranged side by side and second steel bars 62 arranged side by side. The axial direction of the first steel bars 61 is perpendicular to the axial direction of the second steel bars 62. The axial direction of the first steel bars 61 is parallel to the length direction of the side flat die bar 21. When placing, both ends of some of the first steel bars 61 in the steel bar grid 6 are placed on the two supporting bars 51, and the first steel bars 61 are supported by the two supporting bars 51, so as to realize the support of the steel bar grid 6, and the steel bar grid 6 is located in the casting cavity formed by enclosing the two side flat die assemblies 2 and the two concave-convex side die assemblies 3.

[0046] Then, inject concrete slurry into the pouring cavity and compact and vibrate it so that the concrete slurry solidifies to form a concrete slab 7. During the solidification process, an assembly groove 71 corresponding to the convex strip 321 is formed on one side of the concrete slab 7, and an assembly strip 72 corresponding to the concave groove 311 is formed on the other side. The assembly strip 72 is adapted to the assembly groove 71, and the steel bar grid 6 is fixed to the inner side of the outer surface of the concrete slab 7. In this way, it is convenient to splice the concrete slabs 7. During specific assembly, only need to insert the assembly strip 72 of one concrete slab 7 into the assembly groove 71 of another concrete slab 7, then the quick splicing of the two concrete slabs 7 can be realized. And when the concrete slab 7 is in a horizontal use state, through the adapted assembly strip 72 and assembly groove 71, the adjacent concrete slabs 7 can jointly bear the pressure from above. Cooperating with the internal steel bar grid 6, the load-bearing capacity of the concrete slab 7 is greatly enhanced.

[0047] The specific structure of the side flat die assembly 2 in the present utility model is as Figure 11 shown. The cross-section of the side flat die strip 21 is U-shaped. A side flat reinforcement strip 22 consistent with its length direction is fixed inside the side flat die strip 21. The bottom surface of the side flat die strip 21 is attached to the top surface of the pouring table 11. The U-shaped openings of the side flat die strips 21 of the two side flat die assemblies 2 are arranged back to back.

[0048] A further improvement is that plug-in convex shafts 33 are arranged on the opposite surfaces of the side concave die assembly 31 and the side convex die assembly 32. The plug-in convex shafts 33 extend along the length direction parallel to the side flat die strip 21. Each support assembly 5 includes a plug-in member 52 that is plugged and matched with the plug-in convex shaft 33. The plug-in member 52 is detachably connected to the support strip 51; the plug-in member 52 includes a plug-in sleeve 521 adapted to the plug-in convex shaft 33. The plug-in sleeve 521 is connected with a threaded tube 522. The support strip 51 is connected to the threaded tube 522 through a bolt 53.

[0049] Among them, the specific structure of the side convex die assembly 32 is as Figures 5 - 8 shown. The side convex die assembly 32 includes a concave-convex forming strip 35. The length direction of the concave-convex forming strip 35 is horizontal and perpendicular to the length direction of the side flat die strip 21. On the front surface of the concave-convex forming strip 35, that is, the surface facing the side concave die assembly 31, a convex strip 321 of the same length direction is integrally connected. On the back surface of the concave-convex forming strip 35, that is, the surface facing away from the side concave die assembly 31, a concave-convex reinforcement strip 36 of the same length direction is fixedly connected; in the side convex die assembly 32, the ends of the convex strip 321, the concave-convex reinforcement strip 36 and the concave-convex forming strip 35 are flush; on the side of the convex strip 321 facing away from the concave-convex reinforcement strip 36, two plug-in convex shafts 33 are integrally connected. The axial direction of the plug-in convex shafts 33 is horizontal and is spaced along the length direction parallel to the convex strip 321.

[0050] The side concave die assembly 31 corresponding to the side convex die assembly 32, its specific structure is as Figure 9 and Figure 10As shown in the figure, the side female die assembly 31 includes a concave-convex forming strip 35. The length direction of the concave-convex forming strip 35 is horizontal and perpendicular to the length direction of the side flat die strip 21. On the front surface of the concave-convex forming strip 35, that is, the surface facing the side male die assembly 32, a groove 311 with the same length direction is integrally formed. On the back surface of the concave-convex forming strip 35, that is, the surface facing away from the side male die assembly 32, a concave-convex reinforcing strip 36 with the same length direction is fixedly connected; in the side female die assembly 31, the groove 311, the concave-convex reinforcing strip 36 and the ends of the concave-convex forming strip 35 are flush. Two plug-in convex shafts 33 are integrally connected to the bottom of the groove 311. The axial direction of the plug-in convex shafts 33 is horizontal and they are spaced along the length direction parallel to the groove 311.

[0051] The two plug-in convex shafts 33 on the groove 311 and the two plug-in convex shafts 33 on the convex strip 321 are arranged opposite to each other in the horizontal direction; in the plug-in member 52 of the support assembly 5, the plug-in sleeve 521 and the threaded pipe 522 are integrally connected coaxially and are arranged back to back. The inner diameter of the plug-in sleeve 521 is the same as the outer diameter of the plug-in convex shaft 33. The inner cavity depth of the plug-in sleeve 521 is greater than or equal to the length of the plug-in convex shaft 33. In the present utility model, the inner cavity depth of the plug-in sleeve 521 is greater than the length of the plug-in convex shaft 33.

[0052] After adopting the above structure, when installing the support assembly 5, the plug-in sleeve 521 is hermetically sleeved outside the plug-in convex shaft 33. One end of the plug-in sleeve 521 facing away from the threaded pipe 522 is hermetically attached to the corresponding convex strip 321 or groove 311. Then, the two ends of the support strip 51 are respectively connected to the two plug-in members 52 through the bolt 53 and the threaded pipe 522 connected by threads; alternatively, it is also possible to first connect the two ends of the support strip 51 to the two plug-in members 52 respectively through the bolt 53 and the threaded pipe 522 connected by threads, then hermetically sleeve the plug-in sleeves 521 corresponding to the two ends of the support strip 51 outside the plug-in convex shafts 33, and then hermetically attach one end of the plug-in sleeve 521 facing away from the threaded pipe 522 to the corresponding convex strip 321 or groove 311.

[0053] After completing the above operations, the steel bar grid 6 can be placed on the two support strips 51.

[0054] In the closed die state, concrete slurry is injected into the pouring cavity. After the concrete slurry solidifies and forms, at this time, the side female die assembly 31 and the side male die assembly 32 are driven away from each other by the driving assembly 4, and then the solidified concrete slab 7 can be taken out. At this time, an assembly groove 71 and an assembly strip 72 are respectively arranged on both sides of the concrete slab 7. On the bottom of the assembly groove 71 and the surface of the assembly strip 72 away from the assembly groove 71, two plug-in members 52 are fixedly connected by concrete, and the plug-in sleeves 521 of the plug-in members 52 face outward.

[0055] After forming the above structure, as Figures 12 - 14As shown in the figure, when assembling two concrete slabs 7, a docking shaft 73 can be inserted into the insertion sleeve 521 of one of them in advance. The outer diameter of the docking shaft 73 is the same as the inner diameter of the insertion sleeve 521, and the length of the docking shaft 73 is between one time and two times the depth of the inner cavity of the insertion sleeve 521. When splicing the two concrete slabs 7, align the docking shaft 73 with the other insertion sleeve 521, and then bring the two concrete slabs 7 closer. While inserting the assembly strip 72 of one of them into the assembly groove 71, the two ends of the docking shaft 73 can be respectively inserted and matched with the insertion sleeves 521 on the two concrete slabs 7. While ensuring the precise assembly and splicing of the two concrete slabs 7, it avoids the position offset between the two concrete slabs 7 along the length direction of the assembly strip 72.

[0056] A further improvement is that the insertion sleeve 521 is a magnetic conductive part. One end of the insertion sleeve 521 is closed, and the other end is hermetically connected to the corresponding concave-convex side die assembly 3. The concave-convex side die assembly 3 further includes an electromagnet 34 for adsorbing and fixing the insertion sleeve 521.

[0057] Specifically, the connector 52 is made of iron. Concave notches are provided on the side of the convex strip 321 facing away from the casting cavity and on the side of the groove 311 facing away from the casting cavity, and an electromagnet 34 is fixed in the concave notches. In this way, after the connector 52 is sleeved on the insertion convex shaft 33, the electromagnet 34 is energized, so that the connector 52 leans towards the convex top of the convex strip 321 (or the bottom of the groove 311). While ensuring airtight fit, it prevents the position of the connector 52 from shifting during the process of pouring concrete slurry. When demolding is required after the product is formed, the electromagnet 34 is powered off, which facilitates the separation of the connector 52 from the concave-convex side die assembly 3.

[0058] A further improvement is that in the support assembly 5 corresponding to the side concave die assembly 31, the support strip 51 protrudes from the notch of the groove 311. With this design, part of the support strip 51 is located outside the groove 311, which is convenient for laying the steel bar grid 6. Of course, as a replacement with a similar effect, the support strip 51 can also be completely located outside the groove 311.

[0059] A further improvement is that the top surface of the support strip 51 is a serrated surface. Through the design of the serrated surface, after placing the steel bar grid 6, it is beneficial to fix the position of the steel bar grid 6 and prevent the steel bar grid 6 from moving along the length direction of the convex strip 321. Of course, as a replacement with a similar effect, the top surface of the support strip 51 can also adopt a corrugated design.

[0060] A further improvement is that the pouring table 11 includes a bottom formwork 111 and a lifting plate 112. The bottom formwork 111 is horizontally arranged and provided with a lifting through hole 1111 adapted to the lifting plate 112 along its own thickness direction. The lifting through hole 1111 is located between the two side flat formwork assemblies 2 and the two concave-convex side formwork assemblies 3. The bottom formwork assembly 1 further includes a lifting unit 12 for driving the lifting plate 112 to move up and down; both the lifting plate 112 and the lifting through hole 1111 are provided with at least two and correspond to each other one by one.

[0061] Specifically, the pouring table 11 includes a bottom formwork 111 and five lifting plates 112 that are all horizontal. Five lifting through holes 1111 corresponding to and adapted to the lifting plates 112 are provided on the bottom formwork 111. Support feet 1112 are fixed below the bottom formwork 111. The cross-section of the lifting through hole 1111 is square. One of the lifting through holes 1111 is located at the center of the bottom formwork 111, and the other four are located at the adjacent positions of the four corners of the lifting through hole 1111 at the center and inside the pouring cavity.

[0062] The lifting unit 12 includes a lifting oil cylinder 121, a connecting cylinder 122, a connecting sleeve 123, and a support column 124; wherein the cylinder barrel of the lifting oil cylinder 121 is arranged vertically, the bottom end is fixed to the ground, and the top end is fixedly connected to the lifting plate 112; the connecting cylinder 122 extends vertically and is integrally formed on the bottom surface of the lifting plate 112. The axis of the connecting sleeve 123 extends vertically and is fixedly arranged on the four sides of the bottom end of the connecting cylinder 122 respectively. The support columns 124 correspond to the connecting sleeves 123 one by one and are in sliding fit. The bottom ends of the support columns 124 are fixedly connected to the ground, and the top ends are fixedly connected to the bottom formwork 111.

[0063] After adopting the above structure, after the concrete slurry is solidified into the concrete slab 7 and the mold is disassembled, the lifting oil cylinder 121 acts on the lifting plate 112. Under the action of the sliding-fitted connecting sleeve 123 and support column 124, the lifting plate 112 moves steadily upward in the vertical direction, lifting the concrete slab 7 upward and separating it from the bottom formwork 111, which is convenient for taking out the product.

[0064] A further improvement is that the driving assembly 4 includes four translation units 41. The output ends of the four translation units 41 are respectively connected to the two side flat formwork assemblies 2 and the two concave-convex side formwork assemblies 3 correspondingly to drive the two side flat formwork strips 21 and the two concave-convex side formwork assemblies 3 to move in the horizontal direction perpendicular to their own length directions.

[0065] Specifically, the translation unit 41 includes a translation oil cylinder 411, a translation guide sleeve 412, and a translation guide rod 413. The translation oil cylinder 411, the translation guide sleeve 412, and the translation guide rod 413 are axially aligned. The translation guide sleeve 412 is fixed above the bottom template 111 and is slidably engaged with the translation guide rod 413. The cylinder barrel of the translation oil cylinder 411 is fixed to the bottom template 111. Among the two translation units 41, the piston rod of the translation oil cylinder 411 and the translation guide rod 413 are respectively perpendicularly and fixedly connected to the two side flat reinforcement bars 22. Among the remaining two translation units 41, the piston rod of the translation oil cylinder 411 and the translation guide rod 413 are respectively perpendicularly and fixedly connected to the two concave-convex reinforcement bars 36.

[0066] After adopting the above structure, the four translation units 41 can respectively and stably control the two side flat die assemblies 2 and the two concave-convex side die assemblies 3 to move stably in the horizontal direction perpendicular to their own length directions. After the two side flat die assemblies 2 and the two concave-convex side die assemblies 3 move closer to each other, they can be connected end to end in sequence to form a rectangular frame structure as shown in Figure 1 and Figure 2 shown, and enclose with the casting table 11 to form a casting cavity with an open top, that is, perform mold closing. When the two side flat die assemblies 2 and the two concave-convex side die assemblies 3 move away from each other, they can move away from the position where the casting cavity is located and separate from the concrete slab 7 formed by the curing of the concrete slurry, so as to facilitate the lifting unit 12 to drive the lifting plate 112 to move upward to lift the concrete slab 7 to take out the formed product.

[0067] The above is only the preferred embodiment of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and refinements can still be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
