Description

Technical Field

[0001] This utility model relates to the field of prefabricated building construction technology, and in particular to a modular wall. Background Technology

[0002] Prefabricated buildings are constructed by assembling prefabricated components in a work area. Because these components are manufactured in advance according to market and user demands, they offer a range of advantages, including faster construction speed, lower cost, less susceptibility to weather conditions, labor savings, reduced workload and complexity on construction sites, and improved building quality. Currently, prefabricated buildings are increasingly being adopted in my country's construction projects.

[0003] In traditional prefabricated buildings, the connection between two prefabricated walls is often made directly by bolts. This bolted connection method results in weak structural strength at the wall joint, seriously affecting the seismic performance of the prefabricated building. Utility Model Content

[0004] Therefore, it is necessary to provide a prefabricated wall system that can achieve equal strength connection technology for walls and has good seismic performance.

[0005] A prefabricated wall structure includes a first prefabricated wall, a second prefabricated wall, and a high-strength concrete cast-in-place core column;

[0006] The first prefabricated wall includes a first wall panel, a first decorative panel covering the outside of the first wall panel and forming an integral part with the first wall panel, and a first reinforcing steel bar anchored in the first wall panel; a first groove is formed on one end face of the first wall panel along the height direction.

[0007] The second precast wall includes a second wall panel, a second decorative panel covering the outside of the second wall panel and forming an integral part with the second wall panel, and a second reinforcing steel bar anchored within the second wall panel; a second groove is formed on one end face of the second wall panel along the height direction;

[0008] The end face of the first wall panel with the first groove is tightly connected to the end face of the second wall panel with the second groove, so that the inner wall of the first groove and the inner wall of the second groove form a casting cavity with openings at both the top and bottom; the first reinforcing steel bar and the second reinforcing steel bar both extend into the casting cavity, and the two are arranged in an alternating manner.

[0009] Concrete slurry is poured into the casting cavity to form the high-strength concrete cast-in-place core column.

[0010] In one embodiment, one end of the first decorative panel overlaps one end of the second decorative panel to completely cover the high-strength concrete cast-in-place core column.

[0011] In one embodiment, the first groove is formed on the edge of one end face of the first wall panel near the side of the first decorative panel; one end of the first decorative panel serves as part of the inner wall of the first groove.

[0012] The second groove is formed on the edge of one end face of the second wall panel near the side of the second decorative panel; one end of the second decorative panel serves as part of the inner wall of the second groove.

[0013] The first decorative panel is located at one end of the first groove and overlaps with the second decorative panel at one end of the second groove, and together with the inner walls of the first groove and the second groove, respectively, to form the casting cavity.

[0014] In one embodiment, the first prefabricated wall further includes a third decorative panel that covers the outside of the first wall panel and forms an integral part of the first wall panel; one end of the first decorative panel away from the second decorative panel is closely connected or overlapped with one end of the third decorative panel to completely cover the outer side of the first wall panel.

[0015] In one embodiment, when the first wall panel is a corner wall panel, the first decorative panel is an L-shaped panel and covers the outside of the corner of the first wall panel.

[0016] In one embodiment, one end of the first reinforcing bar extends into the second groove and is bent toward the second reinforcing bar, so that the end of the first reinforcing bar located in the casting cavity is L-shaped; one end of the second reinforcing bar extends into the first groove and is bent toward the first reinforcing bar, so that the end of the second reinforcing bar located in the casting cavity is L-shaped.

[0017] In one embodiment, the high-strength concrete cast-in-place core column is internally anchored with a plurality of third reinforcing bars; at least some of the plurality of third reinforcing bars are arranged vertically; the partially vertically arranged third reinforcing bars are fixed to one end of the first reinforcing bar located in the casting cavity, and the remaining vertically arranged third reinforcing bars are fixed to one end of the second reinforcing bar located in the casting cavity.

[0018] In one embodiment, among the plurality of third reinforcing bars, a portion is arranged vertically and the remainder is arranged horizontally; one end of the horizontally arranged third reinforcing bar is fixed to one end of the first reinforcing bar located in the casting cavity or one end of the second reinforcing bar located in the casting cavity.

[0019] The aforementioned prefabricated wall system achieves the connection between the first and second prefabricated wall units by casting high-strength concrete core columns in the casting cavity on-site. Compared to traditional bolt connections, this method significantly improves the strength of the prefabricated wall system. Furthermore, one end of the first and second reinforcing bars is anchored within the first and second wall panels, respectively, while the other end is staggered within the casting cavity and anchored within the high-strength concrete core columns. This enhances the strength of the high-strength concrete core columns, as well as the connection strength between the high-strength concrete core columns and the first and second wall panels, further improving the overall strength of the prefabricated wall system. Additionally, the connection between the first and second prefabricated wall units avoids the most unfavorable stress points at wall corners, further enhancing the overall strength of the prefabricated wall system and effectively increasing the seismic resistance and overall integrity of the prefabricated building constructed from these prefabricated walls.

[0026] Appendix Figure 1 The accompanying drawings illustrate the structure of a modular wall assembly according to one embodiment of the present invention. For ease of explanation, the drawings only show structures relevant to embodiments of the present invention.

[0027] Please see Figure 1 In a preferred embodiment of this utility model, the prefabricated wall 100 includes a first prefabricated wall 110, a second prefabricated wall 120, and a high-strength concrete cast-in-place core column 130.

[0028] The first precast wall 110 includes a first wall panel 111, a first decorative panel 112 covering the outside of the first wall panel 111 and forming an integral part with the first wall panel 111, and a first reinforcing steel bar 113 anchored within the first wall panel 111. A first groove 141 is formed on one end face of the first wall panel 111 along the height direction.

[0029] It should be noted that during the prefabrication process of the first wall panel 111, the first decorative panel 112 can be used as a template on one side during the prefabrication process of the first wall panel 111, while the first reinforcing steel bar 113 is arranged in the molding cavity for casting the first wall panel 111 before the first wall panel 111 is prefabricated. Therefore, after the first wall panel 111 is cast and cured, the first decorative panel 112, the first wall panel 111 and the first reinforcing steel bar 113 will form a whole.

[0030] The second precast wall 120 includes a second wall panel 121, a second decorative panel 122 covering the outside of the second wall panel 121 and forming an integral part with the second wall panel 121, and a second reinforcing steel bar 123 anchored within the second wall panel 121. A second groove 142 is formed on one end face of the second wall panel 121 along the height direction.

[0031] Similarly, the second decorative panel 122, like the first decorative panel 112, can serve as a template on one side during the prefabrication process of the second wall panel 121. The second reinforcing steel bar 123 is also arranged in the molding cavity for casting the second wall panel 121 before the second wall panel 121 is prefabricated. After the second wall panel 121 is cast and cured, the second decorative panel 122, the second wall panel 121, and the second reinforcing steel bar 123 will form a whole.

[0032] One end face of the first wall panel 111 with the first groove 141 is tightly joined to one end face of the second wall panel 121 with the second groove 142, so that the inner walls of the first groove 141 and the inner walls of the second groove 142 form a casting cavity 140 with openings at both the top and bottom. The first reinforcing steel bar 113 and the second reinforcing steel bar 123 both extend into the casting cavity 140 and are arranged alternately.

[0033] Concrete grout is poured into the casting cavity 140 to form a high-strength concrete cast-in-place core column 130.

[0034] During on-site construction, the prefabricated first precast wall 110 and second precast wall 120 are erected in a designated area, and the end face of the first wall panel 111 with the first groove 141 is tightly connected with the end face of the second wall panel 121 with the second groove 142. At this time, the first groove 141 and the second groove 142 form a casting cavity 140. The end of the first reinforcing steel bar 113 located in the casting cavity 140 is staggered from the end of the second reinforcing steel bar 123 located in the casting cavity 140. Then, concrete grout is poured into the casting cavity 140. After the concrete grout solidifies, a high-strength concrete cast-in-place core column 130 is obtained to complete the connection between the first precast wall 110 and the second precast wall 120 on the construction site.

[0035] Thus, the prefabricated wall 100 is connected to the first prefabricated wall 110 and the second prefabricated wall 120 by casting high-strength concrete core columns 130 on-site in the casting cavity 140. Compared with traditional bolt connections, the connection method using high-strength concrete core columns 130 significantly improves the strength of the prefabricated wall 100. Furthermore, one end of the first reinforcing steel bar 113 and the second reinforcing steel bar 123 are respectively anchored in the first wall panel 111 and the second wall panel 121, while the other end is staggered in the casting cavity 140 to be anchored in the high-strength concrete core column 130. This not only enhances the strength of the high-strength concrete core column 130, but also strengthens the connection between the high-strength concrete core column 130 and the first wall panel 111, as well as between the high-strength concrete core column 130 and the second wall panel 121, further improving the overall strength of the prefabricated wall 100. In addition, the connection between the first precast wall 110 and the second precast wall 120 can avoid the most unfavorable position at the corner of the wall, so as to further improve the overall strength of the assembled wall 100, thereby effectively increasing the seismic resistance of the prefabricated building composed of the assembled wall 100 components.

[0036] In some embodiments, one end of the first decorative panel 112 overlaps one end of the second decorative panel 122 to completely cover the high-strength concrete cast-in-place core column 130.

[0037] Thus, when the end face of the first wall panel 111 with the first groove 141 is tightly joined with the end face of the second wall panel 121 with the second groove 142, one end of the first decorative panel 112 overlaps one end of the second decorative panel 122, completely covering the joint between the high-strength concrete cast-in-place core column 130 and the first wall panel 111 and the second wall panel 121, so that no joint is formed between the first precast wall 110 and the second precast wall 120. Therefore, there is no need to carry out joint decoration work on the construction site, and the connection between the first precast wall 110 and the second precast wall 120 can also be made beautiful.

[0038] Of course, in other embodiments, one end of the first decorative panel 112 and one end of the second decorative panel 122 can also be closely connected, which can also achieve the purpose of not needing to do joint decoration work and ensuring the aesthetics of the connection between the first precast wall 110 and the second precast wall 120.

[0039] Furthermore, in some embodiments, a first groove 141 is formed on the edge of one end face of the first wall panel 111 near the side of the first decorative panel 112. One end of the first decorative panel 112 serves as part of the inner wall of the first groove 141. A second groove 142 is formed on the edge of one end face of the second wall panel 121 near the side of the second decorative panel 122. One end of the second decorative panel 122 serves as part of the inner wall of the second groove 142. The end of the first decorative panel 112 located in the first groove 141 overlaps with the end of the second decorative panel 122 located in the second groove 142, and together with the inner walls of the first groove 141 and the second groove 142, respectively, they form a casting cavity 140.

[0040] Thus, during the casting process of the high-strength concrete cast-in-place core column 130, the concrete slurry poured into the casting cavity 140 can directly contact the inner wall of the first decorative panel 112 located at one end of the first groove 141 and the inner wall of the second decorative panel 122 located at one end of the second groove 142, thereby both adhering tightly to the high-strength concrete cast-in-place core column 130. This further improves the connection between the high-strength concrete cast-in-place core column 130 and the first precast wall 110 and the second precast wall 120, and further improves the connection strength between the first precast wall 110 and the second precast wall 120, resulting in higher strength of the assembled wall 100.

[0041] Furthermore, in some embodiments, a wire mesh 150 is provided within the end of the second decorative panel 122 near the first wall panel 111. At least a portion of the wire mesh 150 is located outside the casting cavity 140. The wire mesh 150 can be fixed within the second decorative panel 122 by pre-embedding or by slotting the surface of the second decorative panel 122. Specifically, in this embodiment, the second decorative panel 122 can be gypsum board, PVC board, aluminum composite panel, plywood, MDF, etc., and the wire mesh 150 is pre-embedded within the second decorative panel 122.

[0042] The wire mesh 150 can improve the strength of the second decorative panel 122 at one end of the pouring cavity 140, and prevent the second decorative panel 122 from bending outward after the concrete slurry is poured into the pouring cavity 140. This ensures that the first decorative panel 112 can be accurately attached to one end of the second decorative panel 122, thus improving the reliability of construction.

[0043] Furthermore, in some embodiments, the first prefabricated wall 110 also includes a third decorative panel 114 that covers the outside of the first wall panel 111 and forms an integral part with the first wall panel 111. One end of the first decorative panel 112 away from the second decorative panel 122 is closely abutted or overlapped with one end of the third decorative panel 114 to completely cover the outer side of the first wall panel 111.

[0044] Thus, after the first precast wall 110 and the second precast wall 120 are connected by the high-strength concrete cast-in-place core column 130, the two ends of the first decorative panel 112 overlap the first decorative panel 112 and the second decorative panel 122 respectively, further ensuring the aesthetics of the connection between the first precast wall 110 and the second precast wall 120. The first decorative panel 112, the second decorative panel 122, and the third decorative panel can be the same or different, or the second decorative panel 122 and the third decorative panel 114 can be the same decorative panel that is different from the first decorative panel 112.

[0045] Furthermore, in some embodiments, when the first wall panel 111 is a corner wall panel, the first decorative panel 112 is an L-shaped panel and covers the outer side of the corner of the first wall panel 111. Thus, when the first precast wall 110 and the second precast wall 120 are connected by the high-strength concrete cast-in-place core column 130, the two ends of the first decorative panel overlap the second and third decorative panels respectively, forming an edging decoration at the corner of the first wall panel 111. This perfectly conceals the high-strength concrete cast-in-place core column 130 and forms an overlapping edge on both sides of the corner of the first wall panel 111, making the outer wall of the assembled wall 100 more aesthetically pleasing.

[0046] In some embodiments, there are multiple first reinforcing bars 113. At least some of the first reinforcing bars 113 intersect each other to form a reinforcing mesh structure. There are multiple second reinforcing bars 123, and at least some of the second reinforcing bars 123 intersect each other to form a reinforcing mesh structure. Specifically, the reinforcing mesh structure formed by the first reinforcing bars 113 is distributed throughout the entire first wall panel 111, and the reinforcing mesh structure formed by the second reinforcing bars 123 is distributed throughout the entire second wall panel 121. In this way, by anchoring the reinforcing mesh structure within the first wall panel 111 and the second wall panel 121, the wall strength of the first precast wall 110 and the second precast wall 120 is further improved, which helps to further improve the seismic resistance of the prefabricated wall 100.

[0047] In some embodiments, one end of the first reinforcing bar 113 extends into the second groove 142 and is bent toward the second reinforcing bar 123, so that the end of the first reinforcing bar 113 located in the casting cavity 140 is L-shaped. One end of the second reinforcing bar 123 extends into the first groove 141 and is bent toward the first reinforcing bar 113, so that the end of the second reinforcing bar 123 located in the casting cavity 140 is L-shaped.

[0048] Thus, the first reinforcing bar 113 has an L-shaped end in the casting cavity 140 and extends into the second groove 142, and the second reinforcing bar 123 has an L-shaped end in the casting cavity 140 and extends into the first groove 141. The bending directions of the two are opposite, so that the first reinforcing bar 113 and the second reinforcing bar 123 form an L-shaped hook structure in the high-strength concrete cast-in-place core column 130, which further increases the connection strength between the first wall panel 111 and the high-strength concrete cast-in-place core column 130 and between the second wall panel 121 and the high-strength concrete cast-in-place core column 130, and makes the connection strength between the first precast wall 110 and the second precast wall 120 higher.

[0049] In some embodiments, a plurality of third reinforcing bars 160 are anchored within the high-strength concrete cast-in-place core column 130. At least some of the plurality of third reinforcing bars 160 are arranged vertically. The partially vertically arranged third reinforcing bars 160 are fixed to one end of the first reinforcing bar 113 located in the casting cavity 140, and the remaining vertically arranged third reinforcing bars 160 are fixed to one end of the second reinforcing bar 123 located in the casting cavity 140. The arrangement of the plurality of third reinforcing bars 160 can further enhance the strength of the high-strength concrete cast-in-place core column 130, thereby further improving the connection strength between the first precast wall 110 and the second precast wall 120, and thus making the overall strength and seismic performance of the assembled wall 100 better.

[0050] Furthermore, in some embodiments, a portion of the multiple third reinforcing bars 160 are arranged vertically, while the remainder are arranged horizontally. One end of the horizontally arranged third reinforcing bars 160 is fixed to one end of the first reinforcing bar 113 located in the casting cavity 140 or one end of the second reinforcing bar 123 located in the casting cavity 140. In this way, the multiple third reinforcing bars 160 are anchored in the high-strength concrete cast-in-place core column 130 in both vertical and horizontal arrangements, forming a steel mesh structure within the high-strength concrete cast-in-place core column 130, further enhancing the strength of the high-strength concrete cast-in-place core column 130. This results in a higher connection strength between the first precast wall 110 and the second precast wall 120, thereby improving the overall strength and seismic performance of the assembled wall 100.

[0051] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0052] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the inventive concept, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
