[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This disclosure claims priority to Chinese patent application No. 2024101929945, filed on February 21, 2024, entitled “Concrete building module and its production method,” the entire contents of which are incorporated herein by reference. Technical Field

[0003] The present disclosure generally relates to the technical field of prefabricated buildings, and more particularly to a concrete building module, a prefabricated building, and a method for manufacturing the concrete building module. Background Art

[0004] Currently, box-type precast concrete modules are relatively complex in appearance and difficult to manufacture. The molds used for production are complex and difficult to achieve common molds, resulting in low mold utilization. Essentially, a set of molds can only be used for a single project, and mold costs account for a significant portion of production costs. Some manufacturers utilize a piece-by-piece production method, followed by bolted connections or secondary casting. Bolted boxes have relatively weak joints and poor integrity, making them less earthquake-resistant. Secondary casting requires extensive reinforcement in the precast sheet and requires extensive wet work, making the production process relatively cumbersome. Summary of the Invention

[0073] Hereinafter, specific embodiments of the present disclosure will be described in more detail with reference to the accompanying drawings. These drawings illustrate representative embodiments of the present disclosure and do not limit the present disclosure.

[0074] The present disclosure provides a concrete building module 1 and a production method thereof.

[0075] Referring to Figures 1 to 3 , a concrete building module 1 may include at least three wall panels 15. The at least three wall panels 15 are not all arranged in parallel. Each of the at least three wall panels 15 includes a wall panel body 16 and a pre-anchor 17. The pre-anchor 17 includes a metal plate 18 that is partially exposed relative to the wall panel body 16. The pre-anchors 17 of adjacent wall panels 15 are positioned correspondingly to connect the adjacent wall panels 15.

[0076] According to the concrete building module 1 disclosed herein, pre-anchors 17 are cast together with the wall panel body 16, which reduces the need for molds and helps reduce production costs. The metal plates 18 of the pre-anchors 17 can be welded together, eliminating the need for wet operations such as casting when splicing the wall panels 15. This makes the process more convenient and ensures a strong connection.

[0077] It can be understood that the pre-anchor 17 can be constructed as a metal pre-anchor such as an angle iron, an anchor plate, a channel steel, etc., which is easy to obtain and convenient for subsequent splicing.

[0078] Specifically, referring to FIG3 , the concrete building module 1 may include a top wall panel 10, a first side wall panel 20, and a second side wall panel 30. That is, the at least three wall panels 15 may include the top wall panel 10, the first side wall panel 20, and the second side wall panel 30. The first side wall panel 20 is vertically connected to the lower surface 14 of the top wall panel 10. The second side wall panel 30 is located below the top wall panel 10 and is vertically connected to both the top wall panel 10 and the first side wall panel 20. Alternatively, the concrete building module 1 may include a top wall panel 10 and a first side wall panel 20, with the first side wall panels 20 being two and spaced apart along a first direction D1. That is, the at least three wall panels 15 may include a top wall panel 10 and a first side wall panel 20, with the first side wall panels 20 being two and spaced apart along a first direction D1. Alternatively, the concrete building module 1 may include a top wall panel 10 and second side wall panels 30, wherein the second side wall panels 30 are two in number and spaced apart along the second direction D2, and the two second side wall panels 30 are perpendicularly connected to the lower surface 14 of the top wall panel 10. That is, the at least three wall panels 15 may include a top wall panel 10 and a second side wall panel 30, wherein the second side wall panels 30 are two in number and spaced apart along the second direction D2, and the two second side wall panels 30 are perpendicularly connected to the lower surface 14 of the top wall panel 10. Preferably, the first direction D1 and the second direction D2 are both horizontal and perpendicular to each other.

[0079] Referring to Figure 4 , when a concrete building module 1 includes four wall panels 15, the concrete building module 1 may include a top wall panel 10, a first side wall panel 20, and a second side wall panel 30. In Figure 4 , there is one first side wall panel 20, and two second side wall panels 30, spaced apart along the second direction D2. That is, the four wall panels 15 include a top wall panel 10, a first side wall panel 20, and two second side wall panels 30. The first side wall panel 20 is perpendicularly connected to the lower surface 14 of the top wall panel 10, and the second side wall panel 30 is located below the top wall panel 10 and perpendicularly connected to both the top wall panel 10 and the first side wall panel 20. Referring to Figure 5 , alternatively, there may be two first side wall panels 20 and one second side wall panel 30.

[0080] Referring to Figure 6 , a concrete building module 1 may include five wall panels 15. Specifically, the concrete building module 1 may include a top wall panel 10, a first side wall panel 20, and a second side wall panel 30. There are two first side wall panels 20 and two second side wall panels 30, each spaced apart along a first direction D1, and two second side wall panels 30 spaced apart along a second direction D2. In other words, the five wall panels 15 include the top wall panel 10, two first side wall panels 20, and two second side wall panels 30. The two first side wall panels 20 are perpendicularly connected to the lower surface 14 of the top wall panel 10, while the two second side wall panels 30 are located below the top wall panel 10 and perpendicularly connected to both the top wall panel 10 and the first side wall panels 20.

[0081] Referring back to Figures 1 to 2E , the concrete building module 1 may further include a bottom wall panel 40. In Figure 1 , there are two first side wall panels 20 and two second side wall panels 30. The bottom wall panel 40 is perpendicularly connected to the lower surface 25 of the first side wall panel 20 and the lower surface 35 of the second side wall panel 30. The bottom wall panel 40 is spaced apart from the top wall panel 10 along the height direction DH of the concrete building module 1. It will be appreciated that to enhance the forming strength of the pre-anchor 17 and the wall panel 15, the pre-anchor 17 may further include an anchor bar 19, which is located inside the wall panel 15 and connected to the metal plate 18. Specifically, the top wall panel 10 may include a top wall panel body 11 and a first pre-anchor 12, with the first pre-anchor 12 partially exposed on the lower surface 14 of the top wall panel body 11 (i.e., the metal plate 18 of the first pre-anchor 12 is partially exposed on the lower surface 14 of the top wall panel body 11). Accordingly, the first side wall panel 20 may include a first side wall panel body 21, a first top pre-anchor 22, a first bottom pre-anchor 23, and a first side pre-anchor 24. The first top pre-anchor 22 is partially exposed on an upper surface 26 of the first side wall panel body 21, the first bottom pre-anchor 23 is partially exposed on a lower surface 25 of the first side wall panel body 21, and the first side pre-anchor 24 is partially exposed on a side surface 27 of the first side wall panel body 21 along the first direction D1, which is close to the interior of the concrete building module 1. The second side wall panel 30 may include a second side wall panel body 31, a second top pre-anchor 32, a second bottom pre-anchor 33, and a second side pre-anchor 34. The second top pre-anchor 32 is partially exposed on the upper surface 36 of the second side wall panel body 31, the second bottom pre-anchor 33 is partially exposed on the lower surface 35 of the second side wall panel body 31, and the second side pre-anchor 34 is partially exposed on the side surface 37 of the second side wall panel body 31 along the first direction D1, adjacent to the first side wall panel 20. The bottom wall panel 40 may include a bottom wall panel body 41 and a second pre-anchor 42, with the second pre-anchor 42 partially exposed on the upper surface 43 of the bottom wall panel body 41. It is easy to imagine that the concrete building module 1 can be assembled by aligning the metal plates 18 of the corresponding (i.e., adjacent) pre-anchors 17 of each wall panel 15 and welding them one by one. Figure 2A shows the welded connection between the first side wall panel 20 and the top wall panel 10; Figure 2B shows the welded connection between the second side wall panel 30 and the top wall panel 10; Figure 2C shows the welded connection between the first side wall panel 20 and the second side wall panel 30; Figure 2D shows the welded connection between the first side wall panel 20 and the bottom wall panel 40; and Figure 2E shows the welded connection between the second side wall panel 30 and the bottom wall panel 40.

[0082] Referring to Figure 7 , to facilitate the connection of the wall panels 15, the concrete building module 1 may further include a frame 50. At least three wall panels are connected to the frame 50. The frame 50 may be constructed of interconnected square tubes or other steel materials. For example, in Figure 7 , the frame 50 is hexahedral, and accordingly, there are six wall panels 15, each connected to the frame 50 via pre-anchors 17. It is readily apparent that, in addition to being welded to the frame 50, the corresponding (i.e., adjacent) pre-anchors 17 of each wall panel 15 may also be welded to each other to ensure the connection strength of the wall panels 15.

[0083] Referring to Figures 8 to 10E , the concrete building module 1 may not include a frame 50. To ensure the installation accuracy of the wall panels 15, the concrete building module 1 may include positioning members 60. Referring to Figures 8 and 9 , at least three wall panels 15 each include positioning holes 42a, and the positioning members 60 are connected to the positioning holes 42a of adjacent wall panels 15. For example, in Figure 8 , the concrete building module 1 may include six wall panels 15, each of which includes a positioning hole 42a, and the positioning members 60 are connected to the positioning holes 42a of adjacent wall panels 15. Please refer to Figures 10A to 10E. Figure 10A shows the welding connection between the first side wall panel 20 and the top wall panel 10, and the positioning member 60 is embedded in the positioning holes 42a of both the first side wall panel 20 and the top wall panel 10; Figure 10B shows the welding connection between the second side wall panel 30 and the top wall panel 10; Figure 10C shows the welding connection between the first side wall panel 20 and the second side wall panel 30; Figure 10D shows the welding connection between the first side wall panel 20 and the bottom wall panel 40; and Figure 10E shows the welding connection between the second side wall panel 30 and the bottom wall panel 40.

[0084] It is easy to imagine that the aforementioned concrete building module 1 can be applied to a prefabricated building 100 (see FIG. 11 ). In FIG. 11 , the prefabricated building 100 is composed of a plurality of concrete building modules 1 .

[0085] The method for manufacturing the concrete building module 1 is described in detail below.

[0086] A method for manufacturing a concrete building module 1 is provided, suitable for manufacturing the concrete building module 1. The concrete building module 1 may include a top wall panel 10, a first side wall panel 20, a second side wall panel 30, a bottom wall panel 40, and a positioning member 60. Specifically, at least three wall panels 15 may include the top wall panel 10, the first side wall panel 20, the second side wall panel 30, and the bottom wall panel 40. Each of the aforementioned wall panels 15 includes a wall panel body 16 and pre-anchors 17. The manufacturing method may include the following steps:

[0087] Prefabricate the top wall panel 10 and reserve corresponding positioning holes 42a;

[0088] Prefabricate the first side wall panel 20 and reserve corresponding positioning holes 42a;

[0089] Prefabricate the second side wall panel 30 and reserve corresponding positioning holes 42a;

[0090] Prefabricate the bottom wall panel 40 and reserve corresponding positioning holes 42a;

[0091] Pre-positioning member 60;

[0092] Lift the bottom wall panel 40 to the installation platform 13 (see FIG1 ), adjust the level, and position and fix it;

[0093] Install the positioning member 60 into the positioning hole 42a of the bottom wall panel 40, lift the first side wall panel 20 to the bottom wall panel 40 and align it with the positioning hole 42a of the first side wall panel 20, so that the positioning member 60 is connected to the positioning hole 42a of the first side wall panel 20;

[0094] Adjust the verticality of the first side wall panel 20 and fix it, weld the adjacent pre-anchor members 17 of the bottom wall panel 40 and the first side wall panel 20, and smooth the weld with putty;

[0095] Install the positioning member 60 into the positioning hole 42a of the first side wall panel 20;

[0096] Lift the second side wall panel 30 to the bottom wall panel 40 and align it with the positioning hole 42a of the second side wall panel 30 so that the positioning member 60 is connected to the positioning hole 42a of the second side wall panel 30;

[0097] Adjust the verticality of the second side wall panel 30 and fix it, weld the adjacent pre-anchors 17 of the second side wall panel 30 to the bottom wall panel 40 and the first side wall panel 20, and smooth the welds with putty;

[0098] Install the positioning member 60 into the positioning hole of the second side wall panel 30;

[0099] Lift the top wall panel 10 above both the first side wall panel 20 and the second side wall panel 30 and align it with the positioning holes 42a of the top wall panel 10 so that the positioning members 60 are connected to the positioning holes of the top wall panel 10;

[0100] The top wall panel 10 is adjusted to be level and fixed, and the pre-anchors 17 adjacent to the top wall panel 10 and the first side wall panel 20 and the second side wall panel 30 are welded, and the welds are smoothed with putty.

[0101] It is understandable that when the concrete building module 1 does not include the positioning member 60, the step of reserving the positioning hole 42a can be omitted, and the pre-anchor members 17 of each wall panel 15 can be aligned and then welded.

[0102] Alternatively, a method for manufacturing a concrete building module 1 is provided, suitable for manufacturing the concrete building module 1. The concrete building module 1 may include a top wall panel 10, a first side wall panel 20, a second side wall panel 30, a bottom wall panel 40, and a frame 50. That is, at least three wall panels 15 may include the top wall panel 10, the first side wall panel 20, the second side wall panel 30, and the bottom wall panel 40. Each wall panel 15 includes a wall panel body 16 and pre-anchors 17. The manufacturing method includes the following steps:

[0103] Prefabricated top and wall panels 10;

[0104] Prefabricating a first side wall panel 20;
