Description

Technical Field

[0001] The present application relates to modular construction technology, and in particular to a double-sided composite shear wall connection structure, a prefabricated room module and a building. Background Art

[0002] Double-sided composite wall panels are composed of two layers of prefabricated reinforced concrete slabs connected by trusses or connectors to form a wall panel component with a central cavity.

DETAILED DESCRIPTION

[0043] 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.

[0044] 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.

[0045] 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.

[0046] 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.

[0047] The embodiment of the present application provides a double-sided composite shear wall connection structure, such as Figures 1 to 10 As shown, the double-sided composite shear wall connection structure includes a plurality of wall units 1 connected end to end, the wall unit 1 includes a first wall panel 11, a second wall panel 12, and a connection frame 16 arranged between the first wall panel 11 and the second wall panel 12; the connection frame 16 includes a truss steel bar 161 and a steel mesh 162, and along the length direction of the wall unit 1, the steel mesh 162 is arranged on both sides of the truss steel bar 161; the steel bar usage of a single steel mesh 162 is less than the steel bar usage of a single truss steel bar 161.

[0048] In the embodiment of the present application, the truss steel bars originally located on both sides of the shear wall (i.e., the wall unit 1) are replaced with a steel mesh 162 structure. The steel mesh 162 can play a good fixing role for the first wall panel 11 and the second wall panel 12. While ensuring that the first wall panel 11 and the second wall panel 12 do not move relative to each other, the amount of steel used in the shear wall is effectively reduced, which not only reduces the manufacturing cost of the shear wall, but also reduces the weight of the shear wall, thereby facilitating the transportation and installation and assembly process of the shear wall and improving the production efficiency of the shear wall. The truss steel bars 161 in the middle of the shear wall can still play the main supporting and fixing role, and cooperate with the steel mesh 162 on both sides to ensure the stress stability of the wall unit 1 during production and after installation.

[0049] The double-sided composite shear wall connection structure provided in the embodiment of the present application, by improving the structural form of the connection frame 16, not only reduces the amount of steel bars used, but also reduces the weight of the wall to a certain extent, thereby reducing the manufacturing and transportation costs of the prefabricated wall. In the connection frame 16, only one truss steel bar 161 is provided at the middle position of the wall unit 1, and a steel mesh 162 with less steel bars is provided at each horizontal end of the wall for connection. This can not only ensure the connection strength of the wall and ensure that the first wall panel 11 and the second wall panel 12 do not have relative misalignment during transportation and installation, but also effectively reduce costs, solve the problems of steel bar waste and excessive costs, and have good economic benefits. In addition, the above-mentioned structural form does not significantly increase the complexity of the wall and can still be produced and installed in a relatively simple manner.

[0050] In an exemplary embodiment, Figure 1 and Figure 4 As shown, the top inner side walls of the first wall panel 11 and the second wall panel 12 are provided with a top groove 13, and the bottom inner side walls of the first wall panel 11 and the second wall panel 12 are provided with a bottom groove 14; when multiple wall units 1 are spliced ​​together, the top groove 13 and the bottom groove 14 are connected to form a connecting groove.

[0051] The top and bottom inner walls of the first and second wall panels 11, 12 are each provided with slots to accommodate the connection components when the upper and lower wall units 1 are connected. The slots on the first and second wall panels 11, 12 are arranged to correspond to each other. In other words, the first and second wall panels 11, 12 have corresponding slots to increase the size of the cavity of the wall unit 1 at the slots.

[0052] The top slots 13 and the bottom slots 14 make the installation and positioning of the steel bars during on-site construction simpler and more convenient, thereby improving on-site construction efficiency. The top and bottom slots of the wall facilitate the installation of the steel bars when connecting the upper and lower walls, and the positioning is simple and efficient. In addition, compared to the traditional method of simply placing the connection components without slotting, the slots on the inner wall of the wall panel in the embodiment of the present application increase the space size of the connection components. That is, after slotting, the size of the connection components that can be used to accommodate the connection components along the width direction of the wall unit (that is, the wall thickness direction) increases, thereby making the width dimension of the connection components larger, thereby increasing the reliability of the connection between the upper and lower wall units 1.

[0053] In an exemplary embodiment, Figure 8 As shown, the double-sided composite shear wall connection structure further includes a first connecting steel bar 19 , which is installed in the connection groove. Part of the first connecting steel bar 19 is located in the top groove 13 , and the remaining part is located in the bottom groove 14 .

[0054] The first connecting steel bars 19 serve as the aforementioned connecting components, and are used to connect the upper wall unit and the lower wall unit.

[0055] It should be understood that the connection components may not only be in the form of steel bars, but in some cases, may also be in the form of keels, steel plates, etc.

[0056] The first connecting steel bar 19 is in a U-shape, a rectangle or an ellipse. Of course, the first connecting steel bar 19 can also be in a conventional straight line shape, or other more complex shapes (such as a spiral shape), etc., and this application does not limit this.

[0057] In an exemplary embodiment, Figure 1 and Figure 2 As shown, the connecting skeleton 16 also includes connected transverse steel bars 163 and longitudinal steel bars 164, which are fixed at the intersection position by tension bars 165; the transverse steel bars 163 and longitudinal steel bars 164 are embedded in the first wall panel 11 and the second wall panel 12, or the transverse steel bars 163 and longitudinal steel bars 164 are arranged on the inner walls of the first wall panel 11 and the second wall panel 12.

[0058] Transverse steel bars 163 and longitudinal steel bars 164 are provided in the first wall panel 11 and the second wall panel 12. The transverse steel bars 163 and the longitudinal steel bars 164 are cross-arranged in a horizontal and vertical manner, which effectively improves the strength of the wall panel and ensures that the wall panel is not easy to crack after the wall panel is grooved. At the same time, it ensures that the wall unit 1 has a high strength at the wall panel after the installation is completed.

[0059] The transverse reinforcement 163 and the longitudinal reinforcement 164 can be completed during the wall panel processing process to improve production efficiency. The transverse reinforcement 163 and the longitudinal reinforcement 164 can also be installed on site to adjust according to different construction conditions.

[0060] In an exemplary embodiment, at the side of the top end of the wall unit 1 where the floor slab 3 needs to be connected, the longitudinal reinforcement 164 is bent toward the inside of the wall unit 1 .

[0061] The ends of the longitudinal reinforcement bars 164 are bent inwardly of the wall units 1, providing some reinforcement when connecting the upper and lower wall units 1. This prevents a sharp demarcation between the wall units 1 and the floor slab 3 structure, thereby improving the integrity of the connection between the wall units 1 and the floor slab 3. Furthermore, the inward bending of the ends of the longitudinal reinforcement bars 164 inwardly of the wall units 1 facilitates installation of the floor slab 3 structure, preventing interference.

[0062] In an exemplary embodiment, Figure 1 and Figure 2 As shown, the top slot 13, the bottom slot 14, and the longitudinal steel bars 164 are all provided in plurality; the top slot 13 and the longitudinal steel bars 164 are staggered in the length direction of the wall unit 1; the bottom slot 14 and the longitudinal steel bars 164 are staggered in the length direction of the wall unit 1.

[0063] The top slot 13 and the bottom slot 14 are staggered with the longitudinal steel bars 164 to prevent the longitudinal steel bars 164 from affecting the slot. In addition, the longitudinal steel bars 164 provided on both sides of the slot can better secure the slotted wall and prevent cracking at the slotted wall panel.

[0064] In an exemplary embodiment, Figure 10 As shown, the double-sided composite shear wall connection structure further includes an edge member 2 , and the side ends of the wall units 1 are connected to the edge member 2 .

[0065] Edge members 2 are provided on both sides of the wall unit 1. The edge members 2 can provide high strength for the wall unit 1 to ensure the reliability of the wall unit 1 during and after installation.

[0066] The thickness of the edge member 2 can be set to be the same as that of the wall unit 1 to ensure aesthetics and integrity. Of course, in some applications where higher strength is required, the thickness (size) of the edge member 2 can also be set to be larger so that the edge member 2 can provide higher strength to the wall unit 1. In other words, the thickness of the edge member 2 is greater than the thickness of the wall unit 1.

[0067] In an exemplary embodiment, Figure 10As shown, a second connecting steel bar 21 is provided on the edge member 2, and the second connecting steel bar 21 is inserted into the opening formed at the side end of the first wall panel 11 and the second wall panel 12; the first wall panel 11 and the second wall panel 12 are provided with chamfers 15 at both ends in the length direction of the wall unit 1, and the chamfers 15 are configured to enlarge the opening formed at the side end of the first wall panel 11 and the second wall panel 12, so as to increase the fixing strength of the concrete in the opening to the second connecting steel bar 21.

[0068] The second connecting steel bars 21 on the edge member 2 are inserted into the wall unit 1. The second connecting steel bars 21 serve as a connecting component between the wall unit 1 and the edge member 2, and can effectively improve the connection strength between the two.

[0069] Chamfers 15 are provided at both ends of the first and second wall panels 11, 12 along the length of the wall unit 1. These chamfers create a thicker cavity, capable of accommodating more concrete. This increases the effective thickness of the connection between the wall and the edge member 2 (i.e., the second connecting reinforcement 21). This provides improved load-bearing performance compared to existing double-sided composite shear walls and simplifies construction. The provision of chamfers 15 enhances the connection of the second connecting reinforcement 21 at the opening, ensuring a secure connection between the wall unit 1 and the edge member 2.

[0070] In an exemplary embodiment, a top connection area 17 is formed at the top ends of the first wall panel 11, the second wall panel 12 and the connecting frame 16. The top connection area 17 is configured to connect two adjacent wall units 1, and / or the top connection area 17 is configured to connect the wall unit 1 and the floor slab 3; the top end of the first wall panel 11 protrudes from the second wall panel 12, and the space of the protruding part of the first wall panel 11 toward the side of the second wall panel 12 serves as the top connection area 17; or, the top ends of the first wall panel 11 and the second wall panel 12 are flush, and the upper space of the first wall panel 11 and the second wall panel 12 serves as the top connection area 17.

[0071] The top connection area 17 can be used to connect the upper and lower wall units 1. The aforementioned first connecting steel bars 19 are located in the top connection area 17, with their upper and lower ends located in the upper and lower wall units 1, respectively. The top connection area 17 can also be used to connect the wall units 1 and the floor slab 3. The top connection area 17 and the floor slab 3 are structurally connected and are connected as a whole during the subsequent concrete pouring. Of course, the top connection area 17 can also be used to connect the upper and lower wall units 1 and to connect the wall units 1 and the floor slab 3 simultaneously.

[0072] like Figure 9 As shown, when a floor slab 3 structure is provided on one side of the wall unit 1, the top of the first wall panel 11 is higher than the second wall panel 12, the floor slab 3 structure is provided on one side of the second wall panel 12, and the raised portion of the first wall panel 11 toward the space on the side of the second wall panel 12 serves as a top connection area 17, and the top connection area 17 is connected to the cavity at the floor slab 3 structure.

[0073] When floor 3 structures are set on both sides of the wall structure, the top ends of the first wall panel 11 and the second wall panel 12 are flush, and the upper space of the first wall panel 11 and the second wall panel 12 serves as the top connection area 17, which is connected to the cavity at the floor 3 structure.

[0074] When the floor 3 structure is not provided on both sides of the wall structure, the top ends of the first wall panel 11 and the second wall panel 12 are flush, and the upper space of the first wall panel 11 and the second wall panel 12 serves as the top connection area 17, which is connected to the cavity at the floor 3 structure.

[0075] In an exemplary embodiment, Figure 4 and Figure 5 As shown, the double-sided composite shear wall connection structure further includes closing nets 18 provided at both ends of the wall unit 1 in the length direction. The two closing nets 18 are configured to restrict the concrete at the side ends of the wall unit 1 from flowing into the middle cavity.

[0076] The wall unit 1 and the edge member 2 are connected by pouring concrete. After the shear wall is completed, it is a hollow wall structure. That is, the cavity in the middle of the shear wall will be assembled in place on site and then concrete will be poured to form the final wall structure.

[0077] A closing net 18 is provided to restrict the concrete poured between the wall unit 1 and the edge member 2 from flowing into the middle cavity of the wall unit 1, thereby ensuring the formation of a hollow wall structure and making the wall cavity complete, which is beneficial for the installation of the longitudinal reinforcement 164 and the pouring of concrete at the construction site.

[0078] In an exemplary embodiment, Figure 7 As shown, the steel mesh 162 includes at least two longitudinal bars 1622 and a plurality of transverse bars 1621 , and the two longitudinal bars 1622 are fixed at both ends of the transverse bars 1621 to form a long mesh structure.

[0079] The steel mesh 162 may include two longitudinal bars 1622 and multiple transverse bars 1621 to form a "ladder" shape. Of course, the steel mesh 162 may also include four longitudinal bars 1622 and multiple transverse bars 1621, wherein two longitudinal bars 1622 are located on one side and the other two longitudinal bars 1622 are located on the other side. The transverse bars 1621 are used to connect the longitudinal bars 1622 on both sides to further increase the strength of the steel mesh 162.

[0080] An embodiment of the present application further provides a prefabricated room module, which includes the aforementioned double-sided composite shear wall connection structure.
