[0030] like Figure 1 and Figure 2 As shown, the prefabricated shear exterior wall combined mold-free mold includes a top mold 100, two side molds 200, and a bottom mold 300. The top mold 100 includes a top common mold 110 and a top customized mold. The top common mold 110 is detachably connected to the top customized mold. By changing the length of the top customized mold, the length of the top mold 100 can be changed. One end of the two side molds 200 is detachably connected to the two ends of the top mold 100 in a one-to-one correspondence. The two ends of the bottom mold 300 are connected to the other ends of the two side molds 200 in a one-to-one correspondence. The connection position of the bottom mold 300 to the other ends of the two side molds 200 can be changed.

[0031] The prefabricated shear exterior wall combined demolding-free mold provided by the present invention has a changeable connection position between the bottom mold 300 and the other end of the two side molds 200. By changing the length of the top customized mold, the length of the top mold 100 can be changed, thereby changing the overall size of the demolding-free mold. By adjusting the mold size to adapt to different types of exterior walls, there is no need to frequently replace the mold, which reduces the time for mold replacement and debugging, thereby significantly improving the production efficiency of the prefabricated shear exterior wall; since the reuse rate of the mold is improved, the waste of resources caused by mold scrapping or idleness is reduced, and the cost of mold use is reduced.

[0032] In one embodiment of the present invention, Figure 2 As shown, the top mold 100 includes a top common mold 110, a first top customized mold 120, and a second top customized mold 130. One end of the first top customized mold 120 is detachably connected to one end of a side mold 200, the other end of the first top customized mold 120 is detachably connected to one end of the top common mold 110, the other end of the top common mold 110 is detachably connected to one end of the second top customized mold 130, and the other end of the second top customized mold 130 is detachably connected to one end of another side mold 200. This detachable connection allows the top mold 100 to quickly adjust the combination of its components according to actual needs, flexibly adapting to the production needs of prefabricated shear walls of different sizes and shapes, and enhancing the mold's versatility and adaptability. The simplified installation and disassembly process reduces the time and labor required for mold assembly and disassembly, thereby improving construction efficiency and shortening the production cycle of prefabricated shear walls.

[0033] In one embodiment of the present invention, Figure 2 As shown, the length of the top common mold 110 is greater than the length of the first top custom mold 120 and the length of the second top custom mold 130. As a common component for different exterior wall types, the top common mold 110 has a fixed length and is shorter than the length of all exterior wall types used. By replacing the first and second top custom molds 120, 130, of different lengths, the total length of the top mold 100 can be changed to accommodate different exterior wall types.

[0034] By replacing the first top customized mold 120 and the second top customized mold 130 of different lengths, the total length of the top mold 100 can be quickly adjusted without changing the top common mold 110, thereby adapting to a variety of prefabricated shear facades of different sizes. This design greatly improves the versatility and flexibility of the mold, enabling it to meet diverse production needs. Since the top common mold 110 is a common part for all types of facades and its length is fixed, the types and number of molds can be reduced. By replacing customized molds to adapt to different types of facades, the need to design and manufacture molds separately for each type of facade is avoided, thereby significantly reducing the manufacturing and procurement costs of the molds.

[0035] In one embodiment of the present invention, Figure 2 As shown, the top common mold 110, the first top customized mold 120, and the second top customized mold 130 are all provided with a plurality of vertical holes 130 spaced evenly along their lengths. The vertical holes 130 are used to secure rebar. In this embodiment, the length and width of the vertical holes 130 are equal, that is, each vertical hole 130 has the same length and width. Of course, the length and width of each vertical hole 130 can also be unequal.

[0036] In one embodiment of the present invention, Figure 2 As shown, the top common mold 110 includes a first bottom plate 111, a first side plate 112, two first connecting plates 113, and a plurality of first reinforcing plates 114. The first bottom plate 111 is a rectangular plate, disposed horizontally, and extends along the length of the top mold 100. The first side plate 112 is a rectangular plate, disposed vertically, and extends along the length of the top mold 100. The first side plate 112 is welded to the first bottom plate 111. The first side plate 112 has vertical holes 130 at regular intervals, and the length of the vertical holes 130 is less than the length of the first side plate 112. Two first connecting plates 113 are respectively disposed at both ends of the first bottom plate 111. The first connecting plates 113 are perpendicular to the first bottom plate 111 and the first side plates 112. The first connecting plates 113 are welded to the first bottom plate 111 and the first side plates 112. One first connecting plate 113 is connected to the other end of the first top customized mold 120 via bolts, and the other first connecting plate 113 is detachably connected to one end of the second top customized mold 130 via bolts.

[0037] Multiple first reinforcing plates 114 are equidistantly spaced along the length of the top mold 100, on the side of the first bottom plate 111 and the first side plate 112 facing each other. These first reinforcing plates 114 are located between the two first connecting plates 113. The first reinforcing plates 114 include two first support plates 115 and a first connecting piece 116. The two first support plates 115 are spaced apart along the length of the top mold 100, forming a gap between the two first support plates 115. The gap corresponds to the vertical holes 130 in the first side plate 112. The first support plates 115 are approximately triangular in shape and are welded to the first bottom plate 111 and the first side plate 112. To save material, the first support plates 115 can also be irregularly shaped. The provision of the first support plates 115 improves the connection strength between the first bottom plate 111 and the first side plate 112. The first connecting piece 116 is disposed between the two first support plates 115 and is parallel to the first bottom plate 111.

[0038] In one embodiment of the present invention, Figure 4 and Figure 5 As shown, the first top custom mold 120 includes a second bottom plate 121, a second side plate 122, two second connecting plates 123, and a plurality of second reinforcing plates 124. The second bottom plate 121 is a rectangular plate, disposed horizontally, and extends along the length of the top mold 100. The second side plates 122 are rectangular plates, disposed vertically, and extend along the length of the top mold 100. The second side plates 122 are welded to the second bottom plate 121. The second side plates 122 have vertical holes 130 at regular intervals. The length of the vertical holes 130 is less than the length of the second side plates 122. The distance between two adjacent vertical holes 130 in the second side plates 122 is equal to the distance between two adjacent vertical holes 130 in the first side plates 112, but of course, they can also be unequal. Two second connecting plates 123 are respectively provided at both ends of the second bottom plate 121. The second connecting plates 123 are perpendicular to the second bottom plate 121 and the second side plates 122. The second connecting plates 123 are welded to the second bottom plate 121 and the second side plates 122. One second connecting plate 123 is bolted to one end of a side mold 200, and the other second connecting plate 123 is bolted to the first connecting plate 113 at one end of the second top custom mold 130.

[0039] Multiple second reinforcing plates 124 are equidistantly spaced along the length of the top mold 100 on the side of the second bottom plate 121 and the second side plate 122 facing each other. The multiple second reinforcing plates 124 are located between the two second connecting plates 123. The second reinforcing plates 124 include two second support plates 125 and a second connecting piece 126. The two second support plates 125 are spaced along the length of the top mold 100, forming a gap between the two second support plates 125. The gap corresponds to the vertical holes 130 in the second side plates 122. The second support plates 125 are approximately triangular in shape and are welded to the second bottom plate 121 and the second side plates 122. Of course, to save material, the second support plates 125 can also be irregularly shaped. The provision of the second support plates 125 improves the connection strength between the second bottom plate 121 and the second side plates 122. The second connecting piece 126 is disposed between the two second support plates 125 and is parallel to the second bottom plate 121.

[0040] The structure of the second top customized mold 130 is the same as that of the first top customized mold 120, and will not be described in detail here. The difference from the first top customized mold 120 is that a second connecting plate 123 of the second top customized mold 130 is connected to one end of the other side mold 200 by bolts, and another second connecting plate 123 of the second top customized mold 130 is connected to the first connecting plate 113 at the other end of the second top customized mold 130 by bolts.

[0041] In one embodiment of the present invention, Figure 6 As shown, the side mold 200 includes a side common mold 210, a first side customized mold 220, and a second side customized mold 230. The side common mold 210, the first side customized mold 220, and the second side customized mold 230 are all provided with a plurality of vertical holes 130 at equal intervals along their length. One end of the first top customized mold 120 is detachably connected to one end of one side common mold 210, and the other end of the second top customized mold 130 is detachably connected to one end of the other side common mold 210. The other ends of the two side common molds 210 are detachably connected to the two ends of the bottom mold 300 in a one-to-one correspondence. Both ends of the side common mold 210 are provided with notches. The first side customized mold 220 and the second side customized mold 230 are disposed in the corresponding notches and are detachably connected to the side common mold 210.

[0042] The side common mold 210 includes a third bottom plate, a third side plate, six third connecting plates, and multiple third reinforcing plates. The third bottom plate is a rectangular plate, horizontally arranged, and extends along the length of the side mold 200. The third side plates are rectangular plates, vertically arranged, and extend along the length of the side mold 200. The third side plates are welded to the third bottom plate. The third side plates have vertical holes 130 at regular intervals. The length of the vertical holes 130 is shorter than that of the third side plates, and the distance between two adjacent vertical holes 130 in the third side plates is greater than the distance between two adjacent vertical holes 130 in the first side plates 112.

[0043] Two third connecting plates are respectively provided at both ends of the third bottom plate. The third connecting plate at the end of the third bottom plate near the top mold 100 is perpendicular to the third bottom plate and parallel to the second connecting plate 123. The third connecting plate is welded to the third bottom plate and connected to the second connecting plate 123 via bolts. The third connecting plate at the end of the third bottom plate near the bottom mold 300 is perpendicular to the third bottom plate and perpendicular to the third side plate. The third connecting plate is welded to the third bottom plate and the third side plate and connected to one end of the bottom mold 300 via bolts. The remaining four third connecting plates are respectively provided in groups of two on both sides of the notch. The third connecting plates are perpendicular to the third bottom plate and the third side plate. The third connecting plates are welded to the third bottom plate and the third side plate. Two third connecting plates are connected to both ends of the first side customized mold 220 via bolts, and the remaining two third connecting plates are connected to both ends of the second side customized mold 230 via bolts.

[0044] Multiple third reinforcing plates are equidistantly spaced along the length of the side mold 200, on the side facing each other between the third bottom plate and the third side plate. The multiple third reinforcing plates are located between the two notches. The third reinforcing plates include two third support plates and a third connecting piece. The two third support plates are spaced along the length of the side mold 200, forming a gap between the two third support plates. The gap corresponds to the vertical holes 130 in the third side plates. The third support plates are approximately triangular in shape and are welded to the third bottom plate and the third side plate. The third connecting piece is located between the two third support plates and is parallel to the third bottom plate.

[0045] The first side custom mold 220 includes a fourth side plate 222, two fourth connecting plates 223, and multiple fourth reinforcing plates 224. The fourth side plate 222 is a rectangular plate, vertically arranged, and extends along the length of the side mold 200. The fourth side plate 222 has vertical holes 130 at regular intervals. The length of the vertical holes 130 is shorter than that of the fourth side plate 222, and the distance between two adjacent vertical holes 130 in the fourth side plate 222 is shorter than the distance between two adjacent vertical holes 130 in the third side plate. By replacing the fourth side plate 222 with a different vertical hole spacing, different steel bar spacing requirements can be met.

[0046] The two fourth connecting plates 223 are respectively arranged at both ends of the fourth side plate 222. The fourth connecting plates 223 are perpendicular to the fourth side plate 222 and are welded to the third side plate. The two fourth connecting plates 223 are connected to the third connecting plates on both sides of a gap by bolts.

[0047] Multiple fourth reinforcing plates 224 are equidistantly spaced along the length of the side mold 200 on one side of the fourth side plate 222. The fourth reinforcing plates 224 are located between the two fourth connecting plates 223. The fourth reinforcing plates 224 include two fourth support plates 225 and a fourth connecting piece 226. The two fourth support plates 225 are spaced along the length of the side mold 200, with a gap formed between the two fourth support plates 225. The gap corresponds to the vertical holes 130 in the fourth side plate 222. The fourth support plates 225 are approximately triangular in shape and are welded to the third side plate. The fourth connecting piece 226 is located between the two fourth support plates 225 and is parallel to the fourth bottom plate.

[0048] The structure of the second side customized mold 230 is identical to that of the first side customized mold 220, and the structure of the second side customized mold 230 will not be described in detail here. Similarly, the distance between two adjacent vertical holes 130 in the second side customized mold 230 is smaller than the distance between two adjacent vertical holes 130 in the third side plate. Unlike the first side customized mold 220, the second side customized mold 230 is positioned in another notch, and the two fourth connecting plates 223 of the second side customized mold 230 are connected to the third connecting plates on either side of the other notch via bolts.

[0049] In one embodiment of the present invention, the length of the side common mold 210 is greater than the length of the first side customized mold 220 and the length of the second side customized mold 230 , and the length of the first side customized mold 220 is greater than the length of the second side customized mold 230 .

[0050] In one embodiment of the present invention, Figure 7 As shown, both ends of the bottom mold 300 are provided with strip-shaped through holes 310 extending along the length direction of the bottom mold 300 , and adjustment bolts are provided in the strip-shaped through holes 310 , and the adjustment bolts are connected to the other end of the side common mold 210 .

[0051] Specifically, the bottom mold 300 includes a bottom base plate 320, a bottom top plate 330, and bottom side plates 340. The bottom top plate 330 and bottom side plates 340 are respectively welded to the two long sides of the bottom base plate 320 to form a trough-like structure. The bottom top plate 330 and bottom side plates 340 are arranged in parallel. Strip-shaped through holes 310 are set at both ends of the bottom base plate 320. By changing the position of the adjustment bolts fixed to the bottom base plate 320, the spacing between the two side molds 200 can be precisely controlled to meet the prefabrication requirements of different exterior wall models. This adjustability not only reduces the need for frequent mold replacement due to fixed mold sizes, but also reduces mold manufacturing costs and inventory management costs.

[0052] In one embodiment of the present invention, two strip-shaped through-holes 310 are provided at each end of the bottom mold 300, and the two strip-shaped through-holes 310 are arranged in parallel. These two parallel strip-shaped through-holes 310 provide a more stable support structure for the adjustment bolts, enhancing the connection strength between the bottom mold 300 and the side mold 200. During the concrete pouring process, this structure effectively resists lateral pressure and prevents mold deformation or displacement, thereby ensuring the geometric shape and dimensional accuracy of the precast component.

[0053] like Figure 8 As shown, the present invention also provides a method for using a prefabricated shear external wall combined demoulding-free mold, the method for using is based on the prefabricated shear external wall combined demoulding-free mold described in any one of the above embodiments, and the method for using comprises: In step S100 , the top common mold 110 , the first top customized mold 120 , and the second top customized mold 130 are connected by bolts to form the top mold 100 .

[0054] In step S200 , the side common mold 210 , the first side customized mold 220 , and the second side customized mold 230 are connected by bolts to form the side mold 200 .

[0055] In step S300 , one end of the first top customized mold 120 is connected to one end of one side common mold 210 using bolts, and the other end of the second top customized mold 130 is connected to one end of the other side common mold 210 using bolts.

[0056] In step S400 , the hole mold 400 is placed between the two side molds 200 , and the other ends of the two side common molds 210 are connected to the two ends of the bottom mold 300 in a one-to-one correspondence using bolts.

[0057] Step S500: Place the entire steel cage 500 into a demoulding-free mold and pour concrete.

[0058] In step S600, when the precast concrete exterior wall is demoulded, the demoulding-free mold does not need to be removed, and an overhead crane is used to directly pull the precast concrete exterior wall out of the demoulding-free mold.

[0059] This saves time in demolding. In addition, this demolding-free design significantly improves production efficiency and construction safety.

[0060] Step S700: When the precast concrete exterior wall is produced again, if the model of the precast concrete exterior wall is the same, the steel cage 500 is directly placed in the demoulding-free mold and concrete is poured.

[0061] The reuse rate of demolding-free molds is greatly improved, which reduces the loss and replacement frequency of molds and further reduces production costs.

[0062] Step S800: When the precast concrete exterior wall is produced again, if the model of the precast concrete exterior wall is different, only the first top customized mold 120, the second top customized mold 130, the first side customized mold 220 and the second side customized mold 230 need to be replaced.

[0063] By replacing custom molds, the lengths of the top mold 100 and side molds 200 can be changed, thereby adjusting the overall dimensions of the mold-free mold. This eliminates the need to redesign and manufacture the entire mold set, significantly reducing mold manufacturing and procurement costs. This modular design also simplifies mold assembly and disassembly, reducing the time and labor required for mold replacement, thereby improving production efficiency and shortening the production cycle of prefabricated shear walls.

[0064] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
