DETAILED DESCRIPTION

[0042] In order to make the technical solutions and advantages of the embodiments of the present application more clearly understood, the exemplary embodiments of the present application are further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present application, and are not an exhaustive list of all the embodiments. It should be noted that the embodiments and features in the embodiments of the present application can be combined with each other unless they conflict.

[0043] In the description of this application, it should be understood that the terms "vertical", "horizontal", "inside", "outside", "up", "down", "front", "back", "left", "right", "center", "longitudinal", "transverse", "length", "width", "thickness", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on this application.

[0044] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. Throughout the description of this application, "plurality" means two or more, unless otherwise specifically defined.

[0045] In this application, unless otherwise specified or limited, the terms "mounted," "connected," "connect," "fixed," etc. should be understood broadly. For example, they can refer to fixed connection, detachable connection, or integral connection; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; or internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on specific circumstances.

[0046] The embodiment of the present application provides a shear wall connection structure, such as Figures 1 to 9 As shown, the shear wall connection structure includes a first wall 1 and a second wall 2 connected along the height direction; the first wall 1 is provided with a receiving groove 11 opening toward the second wall 2 at one end thereof facing the second wall 2, and the second wall 2 is provided with a protruding first connecting portion 21 at one end thereof facing the first wall 1; the first wall 1 and the second wall 2 are butt-jointed so that the first connecting portion 21 extends into the receiving groove 11, and the receiving groove 11 is configured to be poured with concrete on site to strengthen the connection strength between the first wall 1 and the second wall 2; the first wall 1 is provided with a first pouring hole 12 extending along the butt-jointing direction, and one end of the first pouring hole 12 is connected to the receiving groove 11; the first pouring hole 12 forms a channel for pouring concrete into the receiving groove 11 after the first wall 1 and the second wall 2 are butt-jointed.

[0047] The following description will be made by taking the case where the first wall 1 is on the top and the second wall 2 is on the bottom for example.

[0048] The bottom of the first wall 1 is provided with a receiving groove 11. The length of the receiving groove 11 can be the same as the length of the first wall 1 or can be less than the length of the first wall 1. Figure 2 and Figure 3 As shown in FIG, the length of the receiving groove 11 is less than the length of the first wall 1. The provision of the receiving groove 11 allows for the wall construction in the embodiment of the present application to be carried out without the need for formwork when pouring concrete in the receiving groove 11, eliminating the need for cast-in-place strips. The time gap between the subsequent pouring of concrete in the pouring hole and the installation of the floor slab 4 is short, which improves the efficiency of on-site construction. Subsequent installation and construction can be carried out without waiting for the concrete in the pouring area to completely solidify, further shortening the construction period.

[0049] After being manufactured at the factory, the first and second walls 1, 2 are transported to the site for assembly and installation. Once the first and second walls 1, 2 are in place, concrete is poured into the receiving groove 11 through the first pouring holes 12. Not only are the first and second walls 1, 2 connected as a whole by the concrete within the receiving groove 11, but the first connecting portion 21 inserted into the receiving groove 11 also provides further securement, improving the reliability of the connection between the first and second walls 1, 2.

[0050] Along the length direction of the receiving groove 11, the number of the first pouring holes 12 can be multiple, for example, the number of the first pouring holes 12 can be 4. The first pouring holes 12 can be cylindrical through holes or other shapes.

[0051] In the shear wall connection structure provided in the embodiment of the present application, the receiving groove 11 and the first connecting portion 21 form a connection structure between the upper and lower walls, and the receiving groove 11 is connected to the first pouring hole 12. After the upper and lower walls are connected, concrete can be poured into the receiving groove 11 through the first pouring hole 12. The first connecting portion 21 is fixed by the concrete in the receiving groove 11, thereby improving the connection strength between the first wall 1 and the second wall 2. In addition, the above connection method does not introduce other complex connection components, and does not require the use of long longitudinal connecting ribs, sleeves, steel frames, etc. for connection, which greatly reduces the project cost. The above connection structure does not generate additional installation steps for the connection components. It only requires pouring concrete, which also shortens the construction period overall.

[0052] In an exemplary embodiment, Figure 3 and Figure 4 As shown, a connecting steel bar 211 is provided at one end of the second wall 2 facing the first wall 1 , and a portion of the connecting steel bar 211 protrudes from the second wall 2 to form a first connecting portion 21 .

[0053] Connecting steel bar 211 is partially embedded in the upper end of second wall 2, while the remaining portion extends from the upper end of second wall 2 and is inserted into receiving slot 11. After connecting steel bar 211 is inserted into receiving slot 11, concrete is poured through first pouring holes 12 provided in first wall 1. This eliminates the need for full-length longitudinal connecting bars, sleeves, or steel framing for connection, reducing construction costs. Furthermore, there is no need to install longitudinal connecting bars or formwork on-site, resulting in efficient and reliable wall installation and improved on-site assembly efficiency.

[0054] To ensure that the first wall 1 and the second wall 2 are tightly connected, the connecting steel bar 211 can be inserted into the receiving groove 11 without contacting the bottom of the receiving groove 11 to avoid interference between the connecting steel bar 211 and the receiving groove 11 and affecting the connection between the first wall 1 and the second wall 2.

[0055] Furthermore, a slot can be further opened at the bottom of the accommodating groove 11, so that part of the connecting steel bar 211 passes through the accommodating groove 11 and extends into the slot; of course, the exhaust problem should be considered when setting the slot to avoid forming a sealed cavity that does not result in concrete being poured in.

[0056] The first connection portion 21 is in the form of a steel bar, which is not only low-cost and easy to construct, but also can provide greater connection strength, thereby ensuring the connection reliability between the first wall 1 and the second wall 2 .

[0057] It should be understood that the first connecting portion 21 may also be in other forms, such as an I-beam or a steel member of other shapes, and the present application does not limit this.

[0058] In an exemplary embodiment, Figure 3 As shown, the length direction of the accommodating groove 11 extends along the length direction of the joint formed by the first wall 1 and the second wall 2; in the length direction of the accommodating groove 11, the number of connecting steel bars 211 is set to multiple; the first pouring hole 12 is set between two adjacent connecting steel bars 211.

[0059] The length direction of the receiving groove 11 is along the length direction of the joint formed by the first wall 1 and the second wall 2 (eg Figure 3 In other words, the length of the receiving groove 11 is the same as the length of the first wall 1 and the second wall 2. Multiple connecting steel bars 211 are evenly spaced along the length of the receiving groove 11 to improve the connection reliability between the first wall 1 and the second wall 2. Of course, the connecting steel bars 211 can also be arranged at non-equidistant intervals.

[0060] The connecting steel bars 211 and the first pouring holes 12 can be staggered to prevent the connecting steel bars 211 from affecting the flow of concrete in the first pouring holes 12 and to prevent the first pouring holes 12 running through the same wall from affecting the embedding effect of the connecting steel bars 211 .

[0061] In an exemplary embodiment, Figure 1 、 Figure 7 、 Figure 8 and Figure 9 As shown, the protruding portion of the connecting steel bar 211 forms a closed ring structure; or, the protruding portion of the connecting steel bar 211 is provided with an opening.

[0062] The protruding portion of the connecting steel bar 211 forms a closed annular structure. For example, the connecting steel bar 211 can be a U-shaped member or a rectangular member. After a portion of the connecting steel bar 211 is inserted into the upper end of the second wall 2, the exposed portion forms a rectangle. It should be understood that the rectangle here can be appropriately deformed. For example, the connecting steel bar 211 can be a shape with a wider lower portion and a narrower top portion. Figure 7 The connecting steel bar 211 may also be provided with an opening at the top of the annular structure after forming the annular structure, that is, the protruding portion of the upper end of the connecting steel bar 211 is provided with an opening (not shown in the figure).

[0063] Of course, the connecting steel bars 211 may also be in other shapes, such as spiral, trapezoidal, etc., and this application does not limit this.

[0064] In an exemplary embodiment, the second wall 2 includes an intermediate layer 22 and side panels 23 located on both sides of the intermediate layer 22. The top ends of the intermediate layer 22 and the side panels 23 form a top mounting area. At the end where the first connecting portion 21 is provided, one of the side panels 23 protrudes from the intermediate layer 22 to form a top groove 24 with both ends open at the end of the second wall 2. Figure 8 As shown, the top groove 24 serves as the top installation area, the upper end opening of the top groove 24 is used to communicate with the receiving groove 11, and the side opening of the top groove 24 is used to communicate with the cavity of the floor 4; alternatively, at the end where the first connecting portion 21 is provided, the two side panels 23 are flush with the middle layer 22, as shown in FIG. Figure 9 As shown, the upper space of the side panels 23 and the middle layer 22 serves as the top mounting area. In this structural form, the upper end space of the second wall 2 can simultaneously communicate with the upper receiving groove 11, the left floor cavity, and the right floor cavity. The side panels 23 protrude from the middle layer 22 to form a top groove 24 with one end open at the end of the second wall 2. The top groove 24 serves as the top mounting area (not shown in the figure).

[0065] The first connecting portion 21 protrudes from the side plate 23 .

[0066] A top groove 24 is provided at the top of the second wall 2 , and concrete enters the receiving groove 11 and the top groove 24 through the first pouring hole 12 , and then flows into other empty parts of the second wall 2 (such as the side groove 25 mentioned later).

[0067] A top groove 24 is provided at the top of the second wall 2, which increases the flow space of the concrete, enables the poured concrete to better fill the cavity of the wall, and avoids the interface between the first wall 1 and the second wall 2 being on the same plane, thereby improving the connection reliability between the first wall 1 and the second wall 2.

[0068] The first connecting portion 21 protrudes from the side plate 23 so that the first connecting portion 21 can extend into the receiving groove 11 .

[0069] In an exemplary embodiment, Figure 2 、 Figure 3 、 Figure 5 As shown, at the two ends of the second wall 2 adjacent to the first connecting portion 21, side panels 23 protrude from the middle layer 22 to form side grooves 25. The shear wall connection structure also includes an edge member 3, with the side grooves 25 configured to connect to the edge member 3. The side ends of the edge member 3 are provided with protruding second connecting portions 31, which extend into the side grooves 25. The side grooves 25 are configured to receive concrete to be poured on-site to strengthen the connection between the second wall 2 and the edge member 3. The two side grooves 25 are each connected to the top groove 24.

[0070] Side grooves 25 are also provided on the side end surfaces of the second wall 2. The left and right sides of the second wall 2 are connected to the edge members 3. During connection, the second connecting portions 31 on the edge members 3 extend into the side grooves 25. Concrete flows through the first pouring holes 12 into the receiving grooves 11 and the top grooves 24, and then into the side grooves 25 of the second wall 2. After the first and second walls 1 and 2 are installed, a single concrete pouring operation is required to connect the walls and the edge members 3, significantly simplifying the construction process and improving efficiency.

[0071] The prefabricated first wall 1 and second wall 2 are not fully poured with concrete, that is, the first pouring hole 12, the receiving groove 11, the top groove 24, and the side groove 25 are all cavities. After the walls are installed in place on site, concrete pouring is carried out on site, thereby reducing the weight of the walls during transportation, improving the construction technology of the walls, and speeding up the construction process.

[0072] In an exemplary embodiment, the first wall 1 and the second wall 2 have the same structure, and a plurality of first walls 1 or second walls 2 are connected end to end to form a complete shear wall.

[0073] The structures of the first wall 1 and the second wall 2 can be set to be the same, that is, the first wall 1 and the second wall 2 are walls of the same structure: the top of the first wall is also provided with a top groove and a first connecting part, and the left and right sides of the first wall are provided with side grooves for connecting edge components; the bottom of the second wall is also provided with a receiving groove, and the second wall is also provided with a through first pouring hole.

[0074] It should be noted that the first pouring hole 12 shown in the figure is actually a pouring hole located on the second wall 22. Since the first wall and the second wall have the same structure, Figure 1 and Figure 2 The wall shown in the figure can be either the first wall 1 or the second wall 2.

[0075] Setting the first wall 1 and the second wall 2 to have the same structural form can reduce production lines. The construction of the prefabricated building can be completed using walls of the same structure, which not only simplifies the construction process but also effectively reduces costs.

[0076] In an exemplary embodiment, Figure 6 As shown, a first bevel 251 is provided at the inner side wall of the opening of the side groove 25 to increase the groove width of the side groove 25 at the opening; a second bevel 111 is provided at the inner side wall of the opening of the accommodating groove 11 to increase the groove width of the accommodating groove 11 at the opening.

[0077] The side grooves 25 and the openings of the receiving grooves 11 are provided with beveled or chamfered structures, so that the width of the groove body at the opening is larger to accommodate more concrete, thereby improving the fixing effect of the concrete at the opening on the connection part, thereby improving the connection effect between the first wall 1 and the second wall 2, as well as the connection effect between the second wall 2 and the edge member 3.

[0078] The specific angle of the bevel can be adjusted according to the situation.

[0079] It should be noted that a similar bevel may also be provided at the opening of the top groove 24 to achieve the same technical effects of "increasing the width of the groove at the opening, and enhancing the fixation of the concrete at the opening to the connection part".

[0080] An embodiment of the present application further provides a prefabricated room module, which includes the aforementioned connection structure between the wall and the support column.

[0081] The prefabricated room module provided in the embodiment of the present application has the aforementioned connection structure between the wall and the support column. The connection between the wall and the support column is reliable and the on-site construction efficiency is high, which reduces the overall construction cost of the prefabricated room module, shortens the construction period of the prefabricated room module, and is conducive to the promotion of the prefabricated room module.

[0082] An embodiment of the present application further provides a building, comprising a plurality of the aforementioned prefabricated room modules, wherein the plurality of prefabricated room modules are connected vertically and / or horizontally.

[0083] The building provided in the embodiment of the present application has the aforementioned prefabricated room modules, with a short overall construction period, reliable connection between adjacent prefabricated room modules, high assembly efficiency, and low construction cost, which is conducive to the further promotion and application of prefabricated buildings.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications that fall within the scope of the present application.
