[0001] The present invention relates to the field of 3D printing architectural technology, and in particular to a 3D printed wall and a printing method thereof. Background Art

[0002] With the application of 3D printing in the construction industry, 3D printed building walls are increasing.

[0003] Currently, commonly used 3D-printed walls typically use a 3D printer to print the outer contour of the wall layer by layer according to a preset path. After printing to the height of a floor or the entire height of the house, vertical steel bars extending perpendicular to the ground are inserted downward from the current height to reinforce the wall. Finally, concrete is poured to complete the 3D printing of the wall. However, due to the high height of a floor or the overall height of the house, in order to reinforce the entire wall, the length of the vertical steel bars must be consistent with the height of the 3D-printed wall. This excessive length makes it difficult to insert the vertical steel bars, complicates the operation, and increases the requirements for construction equipment.

[0004] In order to solve the above problems, it is urgent to provide a 3D printed wall and a 3D printing method. Summary of the Invention

[0050] like Figures 1 to 7As shown, this embodiment provides a 3D-printed wall structure comprising a wall body 100 and at least two support frames 200. The wall body 100 is formed using a 3D printing method. Each support frame 200 comprises a vertically connected horizontal support assembly 210 and multiple vertical support assemblies 220. The multiple vertical support assemblies 220 are arranged parallel to and spaced apart from the horizontal support assembly 210. At least two horizontal support assemblies 210 are arranged parallel to and spaced apart within the wall body 100 along its extension direction, with each vertical support assembly 220 of two adjacent support frames 200 connected end to end. This 3D-printed wall structure eliminates the excessive length of the vertical support assembly 220 in the prior art by dividing it into multiple vertical support assemblies 220. Each segment of vertical support assembly 220 is laid simultaneously with the horizontal support assembly 210, eliminating the need for separate vertical reinforcement, reducing the difficulty of inserting the vertical support assemblies 220, and facilitating construction. Furthermore, the horizontal support assemblies 210 provide additional structural support to the wall body 100. Exemplarily, the horizontal support assembly 210 and the vertical support assembly 220 are both steel bar structures, thereby increasing the strength of the wall body 100. In addition, the extension direction of the wall body 100 is perpendicular to the ground.

[0051] like Figure 2 As shown, this embodiment also provides a method for printing a 3D-printed wall. The method is used to print the above-mentioned 3D-printed wall. The method includes: 3D printing a wall body 100 of a first height; laying a support frame 200 on the upper end surface of the wall body 100; continuing to 3D print the wall body 100 of a second height on the support frame 200; laying a second support frame 200 on the upper end surface of the wall body 100, and connecting the vertical support assembly 220 of the support frame to the vertical support assembly 220 of the previous support frame 200 end to end. This printing method only requires two steps: printing the wall body 100 and laying the support frame 200, eliminating the step of separately inserting vertical steel bars in the prior art. The operation is simple and helps to improve the efficiency of 3D printing walls. The first height and the second height can be the same or different in size, and this embodiment does not limit this.

[0052] Specifically, the wall body 100 includes an outer wall and an inner wall. The outer wall is enclosed to form a closed wall surface, and the inner wall is arranged in the outer wall. The inner wall is arranged in a wavy or broken line shape in the outer wall. The wall body 100 is conducive to improving the structural strength of the wall body 100.

[0053] At the same time, the horizontal support assembly 210 includes a frame 211 and internal reinforcement 212 continuously arranged in the frame 211. The frame 211 and the internal reinforcement 212 are arranged in a one-to-one correspondence with the corresponding structure of the wall body 100. The frame 211 and the internal reinforcement 212 are located on the center line of the corresponding structure of the wall body 100, that is, the outer wall is arranged corresponding to the frame 211, and the inner wall is arranged corresponding to the internal reinforcement 212, which is beneficial to avoid the horizontal support assembly 210 being exposed outside the wall body 100 to ensure the supporting strength of the horizontal support assembly 210.

[0054] See Figure 3 and Figure 4 The middle portion of the vertical support assembly 220 is connected to the horizontal support assembly 210. When printing the wall body 100, the wall body 100 of the first height is printed first, and then the support frame is laid. At this time, the portion of the vertical support assembly 220 located below the horizontal support assembly 210 is inserted downward into the wall body 100, and the portion of the vertical support assembly 220 located above the horizontal support assembly 210 protrudes from the printed wall body 100, and then the wall body 100 is continued to be 3D printed on the upper end surface of the wall body 100. Therefore, the length of the vertical support assembly 220 located above the horizontal support assembly 210 is shorter than the length of the vertical support assembly 220 located below the horizontal support assembly 210, preventing the vertical support assembly 220 located above the horizontal support assembly 210 from interfering with the subsequent 3D printing of the wall body 100.

[0055] The vertical support assembly 220 includes a vertical support member 221 and a connector 222. The vertical support member 221 is connected to the horizontal support assembly 210, and the connector 222 is connected between two adjacent vertical support members 221 connected along the extension direction of the wall body 100, thereby improving the strength of the vertical support assembly 220 and, in turn, the structural strength of the wall body 100. The connector 222 can be located above or below the vertical support member 221, as long as it can connect the two vertical support members 221 end to end. In this embodiment, the connector 222 is provided at the upper end of the vertical support member 221 so that when a second support frame 200 is placed, the lower end of the vertical support member 221 located above can be directly connected to the connector 222 located below.

[0056] like Figures 4 to 6As shown, the connecting member 222 in this embodiment includes a connecting pipe 2221 and a limiting unit 2222. When the two vertical support members 221 are connected end to end along the extension direction of the 3D printed wall, the connecting pipe 2221 is sleeved on the connection between the two vertical support members 221 to connect the two vertical support members 221. The vertical support members 221 here are steel bar structures, and the connecting pipe 2221 is a metal pipe structure. The two vertical support members 221 are connected by the metal pipe. The structure is simple and is conducive to ensuring the structural strength of the vertical support assembly. The limiting unit 2222 is set between the two ends of the connecting pipe 2221 and the vertical support member 221 to constrain the relative position of the connecting pipe 2221 and the vertical support member 221, which is conducive to improving the structural strength of the vertical support assembly. Specifically, the two ends of the connecting tube 2221 are respectively close to one end of the two adjacent vertical support members 221, and the limiting unit 2222 is used to constrain one end of the connecting tube 2221 and one of the vertical support members 221, and at the same time constrain the other end of the connecting tube 2221 and the other vertical support member 221, so as to facilitate the use of the connecting tube 2221 to limit the two vertical support members 221.

[0057] As an optional solution, at least two limit grooves 2211 are provided on the vertical support member 221, and the two limit grooves 2211 are respectively arranged near the two ends of the vertical support member 221. The limit unit 2222 includes at least two limit blocks 2222a. When the vertical support member 221 is inserted into the connecting tube 2221, the limit block 2222a is at least partially located in the limit groove 2211, and each limit groove 2211 is arranged corresponding to at least one limit block 2222a, so that the limit groove 2211 is used to clamp the limit block 2222a, thereby fixing the relative position of the connecting tube 2221 and the vertical support member 221. Specifically, when two limiting grooves 2211 are provided on the vertical support member 221, the two limiting grooves 2211 are respectively arranged near the two ends of the vertical support member 221. In this case, the two ends of the connecting tube 2221 are respectively connected to the two vertical support members 221, with one end of one vertical support member 221 connected to one end of the connecting tube 2221, and the other vertical support member 221, close to one end of the vertical support member 221, is connected to the other end of the connecting tube 2221. Preferably, the limiting groove 2211 at one end of the vertical support member 221 can be connected to a plurality of limiting blocks 2222a, and the plurality of limiting blocks 2222a are arranged at intervals along the circumference of the connecting tube 2221 to improve the stability of the limiting unit 2222.

[0058] In other embodiments, the vertical support member 221 may be provided with three, four, or more limiting grooves 2211. The plurality of limiting grooves 2211 are provided parallel to and spaced apart from each other along the axial direction of the vertical support member 221, near both ends of the vertical support member 221. In this case, each limiting groove 2211 is provided corresponding to at least one limiting block 2222a, which helps to further improve the stability of the connecting pipe 2221 in limiting the two vertical support members 221. Of course, each limiting groove 2211 may also be connected to multiple limiting blocks 2222a at the same time.

[0059] Illustratively, the stopper 2222a is a circular protrusion provided on the connecting tube 2221. When the vertical support member 221 is inserted into the connecting tube 2221, the circular protrusion is inserted into the stopper groove 2211. In other embodiments, the stopper 2222a may be a raised structure provided on the connecting tube 2221 to ensure that the vertical support member 221 is inserted into the connecting tube 2221.

[0060] Furthermore, the limiting groove 2211 is an annular groove, each limiting groove 2211 is correspondingly arranged with multiple limiting blocks 2222a, and multiple limiting blocks 2222a are arranged at circumferential intervals along the limiting groove 2211, which is beneficial to further improve the stability of the connecting pipe 2221 in limiting the two vertical support members 221.

[0061] In other embodiments, a limiting groove 2211 may be provided on the connecting tube 2221, and a limiting block 2222a may be provided on the vertical support member 221. When the vertical support member 221 is inserted into the connecting tube 2221, the limiting block 2222a is at least partially located in the limiting groove 2211, and each limiting groove 2211 is provided corresponding to at least one limiting block 2222a.

[0062] Because the limiting block 2222a is at least partially inserted into the limiting groove 2211 when the connecting tube 2221 is connected to the vertical support member 221, the limiting block 2222a is likely to interfere with the vertical support member 221, resulting in the vertical support member 221 being unable to be inserted into the connecting tube 2221. To address this issue, an inclined surface 2222a1 is provided at one end of the limiting block 2222a near the limiting groove 2211. The inclined surface 2222a1 is inclined toward the end face of the connecting tube 2221 that the limiting block 2222a is near, thereby making it easier for the limiting block 2222a to be inserted into the limiting groove 2211. Specifically, since the connecting pipe 2221 is connected to the two vertical support members 221 respectively, a limit block 2222a corresponding to the limit groove 2211 of each vertical support member 221 is respectively provided on the connecting pipe 2221, and the inclined surface 2222a1 of the limit block 2222a is inclined toward the two ends of the connecting pipe 2221.

[0063] When the limiting block 2222a is inserted into the limiting groove 2211, the end of the inclined surface 2222a1 away from the axial direction of the connecting pipe 2221 is located outside the limiting groove 2211 for easy disassembly.

[0064] A mounting hole is provided on the connecting tube 2221, and the mounting hole extends radially along the connecting tube 2221. The limiting unit 2222 also includes a fixed block 2222b, and the fixed block 2222b is arranged on the mounting hole. The limiting block 2222a is arranged on the fixed block 2222b. The limiting block 2222a can approach or move away from the fixed block 2222b along the extension direction of the mounting hole. Due to the friction between the limiting block 2222a and the vertical support member 221 and the limiting groove 2211, it is easy to wear. By setting the fixed block 2222b and the mounting hole, the replacement of the limiting block 2222a is facilitated.

[0065] The limiting unit 2222 further includes a reset member 2222c, which is disposed between the fixing block 2222b and the limiting block 2222a along the extension direction of the mounting hole. This provides elastic space for the limiting block 2222a to reciprocate while being inserted into and out of the limiting slot 2211. This simplifies the structure and facilitates assembly and disassembly of the vertical support member 221. Of course, in other embodiments, the limiting block 2222a may be a hook structure or the like when the reset member 2222c is not provided.

[0066] like Figure 3 and Figure 7 As shown, in addition, because the horizontal support assembly 210 is arranged corresponding to the centerline of the wall body 100, and the wall body 100 has a certain thickness, if the vertical support assembly 220 is directly connected to the horizontal support assembly 210, the vertical support assembly 220 will be at least partially located inside the wall body 100, making assembly inconvenient. To address the above problems, the support frame 200 in this embodiment also includes a connecting bridge 230. The two ends of the connecting bridge 230 are respectively connected to the horizontal support assembly 210 and the vertical support assembly 220, so that the vertical support assembly 220 is parallel to the wall body 100 and spaced apart. Furthermore, the connecting bridge 230 is arranged coplanar with the horizontal support assembly 210, thereby simplifying the structure of the connecting member 222.

[0067] The support frame 200 also includes multiple mounting seats 240 and multiple first lifting rings. Mounting seats 240 are provided on some of the vertical support components 220 of the support frame 200, and first lifting rings are set on the mounting seats 240. The multiple first lifting rings are arranged in a one-to-one correspondence with the multiple mounting seats 240 to facilitate the assembly and movement of the support frame 200 and the 3D printed wall. When assembling the support frame 200, the lifting device uses the first lifting ring to lift the support frame 200 and move it to a preset position for easy assembly. It is understandable that the support frame 200 is relatively large in size. In order to improve the stability of the lifting support frame 200, there are at least two first lifting rings, and the two first lifting rings are respectively located at both ends of the support frame 200. More preferably, there are three, four or more first lifting rings, and the multiple first lifting rings are arranged accordingly according to the shape of the horizontal support component 210 to ensure the stability of the lifting support frame 200. Optionally, the mounting seat 240 is provided on the vertical support member 221 , and the connecting member 222 may not be provided on the vertical support member 221 provided with the mounting seat 240 .

[0068] Furthermore, since the first lifting ring is prone to friction after repeated lifting, it is a vulnerable part. To facilitate replacement of the first lifting ring, the first lifting ring is detachably connected to the mounting base 240. Furthermore, the first lifting ring is threadedly connected to the mounting base 240 to facilitate assembly and disassembly.

[0069] The support frame 200 further includes a plurality of end covers 250. After the hoisting is completed, the first hoisting ring is removed and the end covers 250 are sleeved on the mounting base 240 to shield the connection port between the mounting base 240 and the first hoisting ring.

[0070] As an optional solution, the support frame 200 further includes a hoisting assembly 260 . The hoisting assembly 260 is disposed on the wall body 100 , and the hoisting assembly 260 can be hoisted to move the wall body 100 .

[0071] The hanging assembly 260 includes a hanging frame 261 and a second hanging ring 262. The hanging frame 261 is parallel to the horizontal support assembly 210 and is arranged on the horizontal support assembly 210. The second hanging ring 262 is arranged at one end of the hanging frame 261, and one end of the hanging frame 261 protrudes from the horizontal support assembly 210, so that after the wall body 100 is formed by the 3D printing method, the second hanging ring 262 protrudes from the wall body 100, thereby providing convenience for moving the wall body 100. Furthermore, the hanging frame 261 is fixedly connected to the horizontal support assembly 210, and the fixed connection here can be welding, riveting or connection by screws. It is understandable that the structure of the second hanging ring 262 can be the same as that of the first hanging ring. In application, if the state of the wall body 100 after printing is completed is perpendicular to the ground, there is no need to set the hanging assembly 260. If the wall body 100 is placed flat on the ground after printing, the operator needs to use the hanging assembly 260 to flip the wall body 100 90 degrees so that it is placed perpendicular to the ground.

[0072] Furthermore, there are multiple hoisting components 260 , and the multiple hoisting components 260 are arranged in parallel and at intervals, thereby improving the stability of the hoisting movable wall body 100 .

[0073] Note that the basic principles and main features of the present invention and the advantages of the present invention are shown and described above. It should be understood by those skilled in the art that the present invention is not limited to the above-described embodiments, which are merely illustrative of the principles of the present invention. Various changes and modifications may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and modifications are intended to fall within the scope of the present invention as claimed, which is defined by the appended claims and their equivalents.
