Description

Technical Field

[0001] The present invention relates to the technical field of prefabrication of D-type concrete interlocking pieces, and in particular to a novel prefabrication mold and a prefabrication method of D-type concrete interlocking pieces. Background Art

[0002] During the channel regulation process of water transport engineering, in order to prevent the shoal from being washed away, the shoal needs to be protected. During the construction process of protecting the shoal, D-type concrete interlocking sheets can be used. Combining D-type concrete interlocking sheets with geotextiles can achieve good protective effects. However, in the prior art, there are few related technologies for prefabricating D-type concrete interlocking sheets. Generally, they are prefabricated through integrated molds. However, during the prefabrication process, the integrated mold cover film may cause damage to the D-type concrete interlocking sheet structure when the mold is removed. In order to prevent large-scale damage to the D-type concrete interlocking sheets, caution is required, which is time-consuming and the efficiency cannot be improved. In view of this, it is necessary to propose a technical solution that can efficiently prefabricate D-type concrete interlocking sheets. Summary of the Invention

[0003] In view of the deficiencies in the prior art, the present invention provides a new mold for prefabricating D-type concrete interlocking sheets, which solves the problem of low prefabrication efficiency of D-type concrete interlocking sheets caused by the lack of technical solutions for efficiently prefabricating D-type concrete interlocking sheets in the prior art.

[0004] According to an embodiment of the present invention, a new type of prefabricated mold for D-type concrete interlocking sheets includes a bottom mold and a cover film covering the bottom mold, wherein the bottom mold and the cover film are respectively provided with a plurality of pairs of lower receiving holes and upper receiving holes opposed to each other, each pair of upper receiving holes and lower receiving holes encloses a mold cavity, and a reserved hole is further provided between the bottom mold and the cover film, and the mold cavity is arranged in regular rows and columns; it also includes a bottom plate, the bottom mold is placed on the bottom plate, and the bottom plate is further provided with a plurality of first through holes respectively surrounding the outside of the lower receiving holes, and the bottom of the bottom plate is also fixedly connected to a lifting bar; a first connecting ear is also fixedly connected to the side wall of the bottom mold, and a second connecting ear is also fixedly connected to the side wall of the cover mold, and the first connecting ear, the second connecting ear and the bottom plate are detachably connected by a locking member. The mold cavity formed by the bottom mold and the cover film is used to introduce concrete, and the bottom plate closes the bottom of the mold cavity at the bottom, so that prefabrication can be carried out. When the mold is subsequently dismantled, the cover mold is removed upwards and then it can be taken out. It is more efficient and less likely to cause accidental damage to the D-type concrete interlocking piece, which can improve the prefabrication efficiency of the D-type concrete interlocking piece.

[0005] Furthermore, a lower groove connected to the lower receiving hole is recessed on the top surface of the bottom mold, and an upper groove connected to the upper receiving hole is recessed on the bottom surface of the cover mold. The upper groove and the lower groove together form a reserved hole.

[0006] Furthermore, the bottom mold is provided with a plurality of second through holes surrounding the lower accommodating groove.

[0007] Furthermore, each mold cavity is connected to four reserved holes.

[0008] Furthermore, a surrounding frame surrounding all the mold cavities is fixedly connected to the cover mold.

[0009] Furthermore, an upper top plate which can respectively press into the lower ends of all the lower receiving holes is fixedly connected to the bottom plate.

[0010] Furthermore, a ring plate is fixedly connected to the lower end of the outer wall of the bottom mold, and the locking piece passes through the ring plate and is connected to the bottom plate.

[0011] Furthermore, the lower accommodating groove and the upper accommodating groove are symmetrically arranged up and down and enclose a structure with a middle section protruding outward in an arc shape, and the top surface of the upper top plate is connected to the inner wall of the lower accommodating groove.

[0012] A method for prefabricating D-type concrete interlocking sheets is also provided, which uses the above-mentioned new mold for prefabricating D-type concrete interlocking sheets, including the following steps: covering the bottom mold on the bottom plate, pre-embedding a polypropylene rope in the reserved holes and connecting all the reserved holes in an S shape, pre-embedding multiple other polypropylene ropes in the reserved holes and arranging the polypropylene ropes connected in the S shape in a cross pattern in a single mold cavity, then buckling the cover mold, locking the cover mold, the bottom mold and the bottom plate, filling concrete into each mold cavity and vibrating the concrete, manually finishing the surface, and after the concrete has initially set, the crane cooperates with manual lifting of the upper mold, and the lifting needs to be smooth to prevent damage to the components. Finally, after the concrete has finally set, the D-type concrete interlocking sheet is lifted out of the bottom mold as a whole through the lifting frame and stacked.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] The provided new mold consists of three parts, which can be prefabricated more efficiently and is less likely to cause accidental damage to the D-shaped concrete interlocking pieces during the removal process. At the same time, it solves the problem of low prefabrication efficiency of D-shaped concrete interlocking pieces caused by the lack of technical solutions for efficient prefabrication of D-shaped concrete interlocking pieces in the existing technology.

[0015] The provided prefabrication method, in conjunction with the provided new mold, can efficiently prefabricate D-shaped concrete interlocking pieces in batches while also avoiding accidental damage to the prefabricated D-shaped concrete interlocking pieces. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] In an exemplary embodiment, Figure 1-3As shown, this embodiment provides a method for prefabricating a D-shaped concrete interlocking sheet, which uses a new type of mold. The new type of mold adopts a split structure, specifically including a bottom mold 1 and a cover mold 2 covering the bottom mold 1. The bottom mold 1 and the cover mold 2 are respectively provided with a plurality of pairs of lower receiving holes 3 and upper receiving holes 4 opposite to each other, each pair of upper receiving holes 4 and lower receiving holes 3 encloses a mold cavity 5, and a reserved hole 6 is further provided between the cover mold 2 and the bottom mold 1. The mold cavity 5 is arranged in regular rows and columns; the new type of mold also includes a bottom plate 7, the bottom mold 1 is placed on the bottom plate 7, and the bottom plate 7 is further provided with a plurality of first through holes 178 respectively surrounding the outside of the lower receiving holes 3, and the bottom of the bottom plate 7 is also fixedly connected to a lifting bar 9 ; A first connecting ear 10 is fixedly connected to the side wall of the bottom mold 1, and a second connecting ear 11 is fixedly connected to the side wall of the cover mold 2. The first connecting ear 10, the second connecting ear 11 and the bottom plate 7 are detachably connected by a locking piece 12. The specific locking piece 12 can be a single-head bolt, which stabilizes them into an integral new mold; Specifically, the lower accommodating groove and the upper accommodating groove are symmetrically arranged up and down and enclosed into a structure with an arc-shaped protrusion in the middle section. In more detail, the bottom plate 7 is also fixedly connected with an upper top plate 13 that can respectively fit into the lower ends of all the lower accommodating holes 3. The top surface of the upper top plate 13 in this solution is connected to the inner wall of the lower accommodating groove, that is, they enclose the outer contour of the D-shaped concrete interlocking piece, and are set at the same time. The upper top plate 13 is inserted into the corresponding lower accommodating groove to form the bottom of the mold cavity 5. The upper top plate 13 also plays a positioning role between the bottom mold 1 and the bottom plate 7. It should be noted that the cooperation between the cover mold 2, the bottom mold 1 and the bottom plate 7 is not seamless. There is a gap between them. During the specific construction, a polypropylene rope 14 is first embedded in the reserved hole 6 and all the reserved holes 6 are connected in series in an S shape. Another plurality of polypropylene ropes 14 are embedded in the reserved holes 6 and the polypropylene ropes 14 connected in series in an S shape are arranged crosswise in a single mold cavity 5. Then, the cover mold 2 is buckled, the cover mold 2, the bottom mold 1 and the bottom plate 7 are locked, and the concrete is filled into each mold cavity 5 and vibrated to compact the concrete. The surface is manually collected. After the initial setting of the concrete, the crane cooperates with manual lifting of the cover mold 2. The lifting needs to be smooth to prevent damage to the components. Finally, after the final setting of the concrete, the D-shaped concrete interlocking piece is hoisted out of the bottom mold 1 as a whole through the hanging frame and stacked. That is to say, each mold cavity 5 is connected with four reserved holes 6. The D-shaped concrete interlocking piece prefabricated in this way forms a grid structure as a whole. The nodes of the grid are single circular prefabricated panels, and the entire grid is the D-shaped concrete interlocking piece (the polypropylene rope 14 is also part of the D-shaped concrete interlocking piece). At the same time, the polypropylene rope 14 can be used for starting the lifting equipment to facilitate the removal and transportation of the D-shaped concrete interlocking piece, simplifying the subsequent construction process and helping to improve the overall beach protection construction efficiency.More specifically, the top surface of the bottom mold 1 is recessed with a lower groove that connects to the lower receiving hole 3, and the bottom surface of the cover mold 2 is recessed with an upper groove that connects to the upper receiving hole 4. The upper and lower grooves together form a reserved hole 6. When placing the polypropylene rope 14, the polypropylene rope 14 can be first stuck in the lower groove, and then the cover mold 2 is closed to place the polypropylene rope 14 in the reserved hole 6, rather than threading it, which can be more efficient.

[0024] like Figure 1-3 As shown, a frame 15 surrounding all the mold cavities 5 is fixedly connected to the cover mold 2. When pouring concrete, a portion of the concrete can be poured on the cover mold 2 first, and then rushed into a single mold cavity 5 through a tool, which saves operation time and further improves efficiency. The frame 15 blocks the concrete to prevent it from falling directly. In more detail, a ring plate 16 is fixedly connected to the lower end of the outer wall of the bottom mold 1. The locking member 12 passes through the ring plate 16 and is connected to the bottom plate 7. That is, the locking member 12 is connected to the first connecting ear 10, the second connecting ear 11, the ring plate 16 and the bottom plate 7, so that the entire new mold is stable. In particular, stud bolts can be used to achieve upper and lower locking below the bottom plate 7 and above the first connecting ear 10, which is more stable. In a further solution, some liquid will seep out during the pouring and curing process. In this solution, a plurality of first perforations 178 respectively surrounding the lower receiving hole 3 are provided on the bottom plate 7, so that the first perforations 178 can allow the seeping liquid to quickly pass downward through the bottom plate 7. At the same time, there is a lifting bar 9 under the bottom plate 7 to lift the bottom plate 7, so that the liquid can leave the bottom plate 7 more smoothly, avoiding excessive liquid retention between the bottom plate 7 and the supporting surface (there will be cement residue in the liquid, and excessive retention may cause the cement to solidify and bond the bottom plate 7 and the bottom surface together); in a further detailed solution, a plurality of second perforations 18 surrounding the lower receiving groove are also provided on the bottom mold 1. The second perforations 18 can receive the liquid from between the cover mold 2 and the bottom mold 1, and continue to enter the first perforations 178 after downward and then leave the bottom plate 7, while the first perforations 178 can receive the liquid from the second perforations 18 and from between the bottom mold 1 and the bottom plate 7.

[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not limiting. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the purpose and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
