Prefabricated buildings have the advantages of high efficiency and high precision, and have been used in more and more construction projects.

[0056] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0057] <Example 1>

[0058] like Figures 1 to 3 As shown, this embodiment provides a high-precision prefabricated component mold, including: at least one first molding mold 1, which is provided with at least three non-collinear first positioning parts 11, and the three non-collinear first positioning parts 11 can adjust the orientation of the first molding mold 1; and at least one second molding mold 2, which is provided with at least three non-collinear second positioning parts 21, and the three non-collinear second positioning parts 21 can adjust the orientation of the second molding mold 2; wherein, the molding surface 4 determined by the first positioning part 11 has a perpendicular midline L1, and the molding surface 4 determined by the second positioning part 21 has a perpendicular midline L2, and the intersection of the perpendicular midline L1 and the perpendicular midline L2 serves as the origin of the assembly coordinate system of the prefabricated component mold. The first positioning part 11 and the second positioning part 21 can make the perpendicular midline L1 and the perpendicular midline L2 intersect, which can avoid the problem of poor assembly positioning accuracy caused by wear and deformation of the edge part of the mold in the prior art, and ensure repeated production of high-precision prefabricated components. The perpendicular bisector L1 refers to a line passing through the center point of the molding surface 4 determined by the first positioning portion 11 and perpendicular to the molding surface 4. The perpendicular bisector L2 refers to a line passing through the center point of the molding surface 4 determined by the second positioning portion 21 and perpendicular to the molding surface 4. The molding surface 4 refers to the surface of the molding cavity formed by the first molding mold 1 or the second molding mold 2.

[0059] For further information, see Figures 1 to 4 The first positioning portion 11 includes a first connecting hole 111 provided on the first molding die 1, and the second positioning portion 21 includes a second connecting hole 211 provided on the second molding die 2. The first connecting hole 111 and the second connecting hole 211 can be connected to the external mold frame 6 respectively. The first molding die 1 and the second molding die 2 are respectively installed on the external mold frame 6 through the first connecting hole 111 and the second connecting hole 211, so as to fix the molding cavity surrounded by a plurality of first molding die 1 and the second molding die 2. Preferably, the first connecting hole 111 of the first molding die 1 and the second connecting hole 211 of the second molding die 2 are respectively adjustably connected to the external mold frame 6 through the connecting rod 7. For example, one end of the connecting rod 7 is fixed on the external mold frame 6, and the orientation of the first molding die 1 is adjusted by the different depths of the other end of each connecting rod 7 entering the first connecting hole 111. The same is true for the second molding die 2, so as to ensure that the first molding die 1 and the second molding die 2 can be accurately spliced ​​to form a predetermined molding cavity and produce high-precision prefabricated components.

[0060] For further information, see Figures 1 to 4The first connection hole 111 is arranged on the side of the first molding die 1 facing away from the molding cavity of the prefabricated component mold, and the second connection hole 211 is arranged on the side of the second molding die 2 facing away from the molding cavity of the prefabricated component mold, and the first connection hole 111 and the second connection hole 211 are not connected to the molding cavity. Such an arrangement can protect the molding surface 4 of the mold, prevent the first connection hole 111 and the second connection hole 211 from affecting the molding surface 4 of the mold, and improve the surface quality of the produced prefabricated component.

[0061] Preferably, see Figures 1 to 4 , the minimum distance between the first positioning portion 11 and the midline L1 is greater than the minimum distance between the first positioning portion 11 and the edge of the first molding die 1; compared with setting the first positioning portion 11 at a position close to the midline L1, setting the first positioning portion 11 at a position relatively close to the edge of the first molding die 1 can make the molding surface 4 of the first molding die 1 deflect by a larger amplitude under the same adjustment amplitude of the first positioning portion 11, and can facilitate the adjustment of the orientation of the molding surface 4 of the first molding die 1 through the first positioning portion 11, and the adjustment efficiency is higher. Preferably, the minimum distance between the second positioning portion 21 and the midline L2 is greater than the minimum distance between the second positioning portion 21 and the edge of the second molding die 2, and its technical effect is similar to the effect of the first positioning portion 11 adjusting the orientation of the first molding die 1.

[0062] <Example 2>

[0063] In this embodiment, the same parts as those in the first embodiment are given the same figure marks, and the same text descriptions are omitted.

[0064] Compared with the first embodiment, the high-precision prefabricated component mold provided in this embodiment has the following different structural designs:

[0065] See also Figure 2 and Figure 3 When a prefabricated component is produced by a high-precision prefabricated component mold, the first molding die 1 can be used to mold the end face of the prefabricated component, and the second molding die 2 can be used to mold the side face of the prefabricated component. Figure 3 , Figure 5 and Fig. 9 , the top of the molding cavity of the mold can be set to be open, and the concrete aggregate can be injected into the molding cavity through the open port. Alternatively, the molding cavity of the mold has an injection port, specifically, the first molding die 1 is provided with an injection port or the second molding die 2 is provided with an injection port, and the concrete aggregate is injected into the molding cavity through the injection port. The prefabricated component mold provided by the present invention can be used to produce various prefabricated components such as prefabricated columns, prefabricated beams, prefabricated walls, etc., and a plurality of first molding dies 1 and second molding dies 2 are used to form an adapted molding cavity to produce prefabricated components of different specifications and shapes.

[0066] For further information, see Figure 7 , Figure 8 , Figures 11 to 14 The first positioning portion 11 includes one of a positioning protrusion 31 and a positioning groove 32 arranged on the side of the first molding die 1 facing the second molding die 2, and the second positioning portion 21 includes the other of a positioning protrusion 31 and a positioning groove 32 arranged on the side of the second molding die 2 facing the first molding die 1. The positioning protrusion 31 and the positioning groove 32 can be mutually socket-fitted; in the process of splicing and assembling the first molding die 1 and the second molding die 2, the positioning protrusion 31 and the positioning groove 32 can play a stable guiding and limiting role, so that the first molding die 1 and the second molding die 2 can be spliced ​​with high precision, and the precision of the overall shape of the molding cavity is improved, so as to improve the quality of the prefabricated component products produced. Please refer to Fig.11 and Fig.12 The first molding die 1 is provided with a positioning groove 32 toward the second molding die 2 , and the second molding die 2 is provided with a positioning protrusion 31 toward the first molding die 1 .

[0067] Furthermore, the first molding die 1 and / or the second molding die 2 comprises at least two mold plates 33 that are fastened together, one of the two adjacent mold plates 33 is provided with at least a positioning protrusion 31, and the other of the two adjacent mold plates 33 is provided with at least a positioning groove 32. Figures 6 to 9 as well as Figures 11 to 14 Taking the second molding die 2 as an example, the second molding die 2 includes at least two fastened templates 33, and the two adjacent templates 33 are spliced ​​and matched by the positioning protrusions 31 and the positioning grooves 32. Taking the production of cylindrical parts by high-precision prefabricated component molds as an example, the template 33 used to shape the area with a corner cross section of the molding cavity is called a corner mold 331, and the template 33 used to shape the area with a straight cross section of the molding cavity is called an edge mold 332. The corner molds 331 and the edge molds 332 arranged alternately in the circumferential direction are sequentially spliced ​​to form the second molding die 2. Such an arrangement allows the corner molds 331 and the edge molds 332 to be removed separately when demolding, thereby improving the demolding efficiency and avoiding damage to the prefabricated components when demolding.

[0068] Preferably, the perpendicular midlines of the molding surfaces 4 of the corner mold 331 and the edge mold 332 located in the same second molding mold 2 intersect with the perpendicular midline of the molding surface 4 of the first molding mold 1. Such an arrangement can ensure that each mold plate 33 is accurately spliced ​​with the first molding mold 1, improve the flatness of the mold molding cavity, and thus make the surface of the produced prefabricated component smooth. The surface where the template 33 contacts the template 33 is called the splicing surface. The corner mold 331 and the side mold 332 can be respectively provided with positioning protrusions 31 or positioning grooves 32 on each splicing surface, that is, a corner mold 331 can be spliced ​​with the positioning groove 32 on one side mold 332 through the positioning protrusion 31, or can be spliced ​​with the positioning protrusion 31 on another side mold 332 through the positioning groove 32 on its other splicing surface. It can be understood that continuous positioning protrusions 31 or continuous positioning grooves 32 may appear at the junction of two adjacent splicing surfaces of the corner mold 331. Of course, the two adjacent splicing surfaces may also be positioning protrusions 31 and positioning grooves 32 respectively; the same is true for the side mold 332 and for each template 33 forming the first molding mold 1. Figures 6 to 9 The first molding die 1 shown in the figure is a whole plate, and can actually be formed by splicing a plurality of templates 33 , similar to the above-mentioned edge die 332 and corner die 331 , through the socket fit of the positioning protrusion 31 and the positioning groove 32 .

[0069] For further information, see Figures 6 to 9 as well as Figure 11 to Figure 12 The corner mold 331 and the side mold 332 are sequentially spliced ​​like building blocks. For example, two corner molds 331 can be connected to the same splicing surface of a side mold 332. It can be understood that Figures 6 to 9 The mold cavity shown is roughly a columnar structure. In fact, the mold cavity shape can be roughly a plate-shaped or block-shaped structure through the first molding mold 1 and the second molding mold 2, so as to produce prefabricated walls, prefabricated blocks and other components. It can be understood that a few templates 33 can also be installed on the upper surface of the mold to reserve a channel for distributing materials into the mold.

[0070] Furthermore, the positioning protrusions 31 and the positioning grooves 32 are continuously or alternately distributed on the edge contours of the first molding die 1 and the second molding die 2. Figures 10 to 12 , the positioning grooves 32 are continuously distributed on the edge contour of the first molding die 1, and the positioning protrusions 31 are continuously distributed on the edge contour of the second molding die 2. It can be understood that the first molding die 1 can also be provided with positioning protrusions 31, and the second molding die 2 can also be provided with positioning grooves 32; or, the first molding die 1 and the second molding die 2 can both be provided with positioning protrusions 31 and positioning grooves 32; the positioning protrusions 31 and positioning grooves 32 shown in the figure are continuous, but they can actually be discontinuous, as long as the first molding die 1 and the second molding die 2 can be socket-fitted through the positioning protrusions 31 and the positioning grooves 32.

[0071] Preferably, the positioning protrusions 31 and the positioning grooves 32 are continuously or alternately distributed on the joint surface of two adjacent templates 33. Figures 11 to 14 In the process of splicing the corner mold 331 and the side mold 332, a continuous positioning protrusion 31 is provided on the splicing surface of one of the two, and a continuous positioning groove 32 is provided on the other and matching splicing surface of the two. In the process of splicing the corner mold 331 and the side mold 332, the positioning protrusion 31 and the positioning groove 32 can play a stable guiding role. At the same time, the positioning protrusion 31 can be engaged with the positioning groove 32 so that the adjacent corner molds 331 and the side molds 332 are pressed against each other, so that the splicing gaps between the mold plates 33 are equal. The positioning protrusion 31 and the positioning groove 32 shown in the figure are continuous. In fact, the positioning protrusion 31 and the positioning groove 32 can also be discontinuous, as long as the two adjacent mold plates 33 can be engaged with the positioning protrusion 31 and the positioning groove 32.

[0072] Furthermore, the first molding die 1 and the second molding die 2 or the two mold plates 33 that match each other are provided with a through connection hole 1 311 and a through connection hole 2 321 at the positioning protrusion 31 and the positioning groove 32, respectively. The connection hole 1 311 and the connection hole 2 321 together form a through reaming hole. Fig.15 The two matching templates 33 are respectively provided with a penetrating connection hole 1 311 and a connection hole 2 321 at the positioning protrusion 31 and the positioning groove 32. The connection hole 1 311 and the connection hole 2 321 together constitute a through-going reamed hole. The template 33 with the positioning protrusion 31 and the template 33 with the positioning groove 32 can be connected by a reamed hole bolt assembly passing through the reamed hole. At the same time, setting the reamed hole at the positioning protrusion 31 and the positioning groove 32 can further strengthen the connection and cooperation between the positioning protrusion 31 and the positioning groove 32, so that the connection between the two spliced ​​templates 33 is more stable.

[0073] For further information, see Figures 5 to 9 as well as Fig.11 and Fig.12 , at least part of the first molding die 1 is provided with main rib positioning holes 34 arranged around the midline L1, and / or, at least part of the second molding die 2 is provided with main rib positioning holes 34 arranged around the midline L2. The rigid skeleton placed in the mold can be connected to the first molding die 1 and the second molding die 2 through the main rib positioning holes 34, so as to locate the position of the rigid skeleton in the mold, avoid the movement of the rigid skeleton during the laying of the material, and make the thickness of the protective layer at various locations of the prefabricated component after production meet the design. At the same time, the main rib end of the rigid skeleton can be provided with a connecting nut, and the connecting nut is detachably connected to the main rib positioning hole 34, so that the connecting nut is exposed on the outer surface of the prefabricated component after production, which is convenient for the prefabricated component to be connected with other components.

[0074] Furthermore, two adjacent templates 33 are connected by one or more combinations of screw connection, snap connection, pin connection, and magnetic connection. Through these detachable connection methods, the mold as a whole is split, which is convenient for assembly and disassembly. At the same time, the templates 33 can be removed one by one when the prefabricated component is demoulded. There is no need to demould the prefabricated component by pulling it out of the entire mold, which avoids damage to the surface of the prefabricated component during the demoulding process, further improving the product quality of the prefabricated component; at the same time, there is no need to consider the mold parting surface and the demoulding slope, and the shape of the outer surface of the prefabricated component can be designed to be more complex, thereby improving the diversity of prefabricated component products. It should be noted that the first molding mold 1 and the second molding mold 2 are actually two adjacent templates.

[0075] Furthermore, a sealant is filled at the joint between two adjacent templates 33. Filling the gap at the joint between two adjacent templates 33 with a sealant can effectively prevent mold leakage, improve the quality of the prefabricated component products, and facilitate demoulding.

[0076] For further information, see Figures 6 to 9 The mold includes two first molding molds 1 arranged at intervals and a plurality of second molding molds 2 arranged between the two first molding molds 1. When the specifications of the mold need to be changed, it can be achieved by increasing or decreasing the number of second molding molds 2. It can be understood that the templates 33 of adjacent second molding molds 2 can also be spliced ​​in the above manner.

[0077] <Example 3>

[0078] In this embodiment, the same parts as those in Embodiments 1 and 2 are given the same figure marks, and the same text descriptions are omitted.

[0079] Compared with the first and second embodiments, the high-precision prefabricated component mold provided in this embodiment has the following different structural designs:

[0080] See also Fig.16 The final prefabricated component 8 has a protruding surface embedded plate 5 on its outer surface. Figures 6 to 9 as well as Fig.11 and Fig.12 At least one second molding die 2 is provided with a strip through hole 35 connected to the molding cavity surrounded by the prefabricated component mold, and the strip through hole 35 allows the adapted embedded plate 5 to enter the molding cavity from the outside and be exposed on the outer surface of the second molding die 2. For example, refer to Fig.11 and Fig.12The side template 33 of the second molding die 2 is provided with a strip through hole 35, and the embedded plate 5 can be stuck in the strip through hole 35, so that the final prefabricated component 8 produced is the embedded plate 5 protruding from the concrete surface of the prefabricated component. At the same time, the gap between the embedded plate 5 and the strip through hole 35 can also be sealed by a filling piece, and the filling piece can be selected from rubber, plastic or other foaming hardening materials.

[0081] For further information, see Fig.11 and Fig.12 , at least part of the cross section of the strip-shaped through hole 35 includes at least one bending section, so that it can adapt to the embedded plate 5 whose cross section includes at least one bending section. Fig.12 , corresponding strip-shaped through holes 35 are provided on both lateral sides of the second molding die 2, which is equivalent to that both ends of the embedded part are exposed on the outer surface of the second molding die 2, so that a prefabricated component with an embedded plate 5 that penetrates the molding cavity and the second molding die 2 can be produced. Furthermore, the hardness of the second molding die 2 is greater than the hardness of the embedded plate 5. Such a setting enables the embedded plate 5 to enter the molding cavity through the strip-shaped through hole 35. The strip-shaped through hole 35 can correct the shape of the embedded plate 5. At the same time, the position accuracy of the embedded plate 5 can be ensured by the strip-shaped through hole 35, so that the position of the embedded plate 5 on the final prefabricated component is relatively fixed, which is convenient for the prefabricated component 8 to be connected with other components through the embedded plate 5 later.
