Description

Technical Field

[0001] This application relates to the technical field of prefabricated buildings, and particularly to an in-plane modular superposed shear wall. Background Art

[0002] The structural forms of high-rise modular buildings are mostly affected by the local market and industry. The practices of precast shear walls vary. According to different assembly shear wall methods, it can be divided into a box formwork - cast-in-place shear wall system and a box formwork - precast shear wall system. Among them, the box formwork - cast-in-place shear wall system uses a formwork shell to replace the formwork and is a monolithic cast-in-place shear wall. The box formwork - precast shear wall system integrates the longitudinal bars of the shear wall with the box formwork and is a precast assembled shear wall.

[0003] To adapt to the local construction market, existing modular buildings mostly adopt cast-in-place shear wall structures. This feature makes the formwork shell (including truss bars) of the modular box formwork only serve as a permanent formwork and does not participate in the structural calculation, which will cause the structure to be too rigid and heavy. However, the on-site cast-in-place construction process is cumbersome, requiring steel bar binding, formwork erection, concrete pouring, curing and form removal, surface plastering treatment, etc., resulting in problems such as a long construction period, a large number of on-site workers, and at the same time, there are also problems of material loss such as formwork and a large amount of construction waste, and it is still impossible to build a house on-site "like building blocks".

[0004] In modular buildings, some concrete module boxes are close to the center of the building, and some are close to the outermost side of the building. According to the different positions of the concrete module boxes in the building, the requirements for the structural strength, etc. of the concrete module boxes are also different. The wall leaves on the side where adjacent concrete module boxes are close to each other are connected to form a superposed shear wall. In the design process of the superposed shear wall, in addition to being convenient for construction, it is also necessary to ensure that its structural strength meets the requirements and is not overly conservative resulting in high costs.

[0015] In some examples, the plane where the rectangular stirrup is located is perpendicular to the horizontal steel bar, and the same rectangular stirrup is coplanar and connected to one vertical steel bar in each of the two steel bar meshes.

[0036] Figure 1 It is a schematic diagram of a partial structure of a modular building provided by an embodiment of the present application. As Figure 1 shown in the top view, the modular building includes a plurality of concrete module boxes 100. Figure 1 Only a part of one layer of the modular building is shown in [the figure]. In the height direction, the concrete module boxes 100 can also be stacked. Among the plurality of concrete module boxes 100, according to different distribution positions, they can be divided into edge modules and in-plane modules. The edge module refers to the concrete module box 100 closest to the outermost side of the building, such as Figure 1 the two concrete module boxes 100 located on the outside in [the figure]. The in-plane module refers to the concrete module box 100 closest to the center of the building, such as Figure 1 the two concrete module boxes 100 located on the inside in [the figure].

[0037] Figure 2 It is a schematic structural view of two adjacent concrete modular boxes provided by an embodiment of the present application. Figure 2 In [figure], the two concrete modular boxes are appropriately separated. An embodiment of the present application provides an in-plane modular composite shear wall, which forms the wall on the side where two in-plane modules approach each other, that is, the in-plane modular composite shear wall is the common wall of the two in-plane modules.

[0038] Figure 3 It is a schematic exploded view of an in-plane modular composite shear wall provided by an embodiment of the present application. As Figure 3 shown, the in-plane modular composite shear wall includes a wall body 10. Among them, the wall body 10 includes a first module precast wall leaf 11 and a second module precast wall leaf 12. The in-plane modular composite shear wall also includes two steel mesh sheets 20, a plurality of rectangular tie bars 30, and a plurality of tie bolts 70. In the drawings provided by the embodiment of the present application, in order to show the steel mesh sheets 20, at least a part of the first module precast wall leaf 11 and a part of the second module precast wall leaf 12 are omitted.

[0039] The first module precast wall leaf 11 and the second module precast wall leaf 12 are arranged in parallel at intervals. When the in-plane modular composite shear wall is constructed on site, the space between the first module precast wall leaf 11 and the second module precast wall leaf 12 is used for pouring concrete. The orthographic projection of the first module precast wall leaf 11 on the second module precast wall leaf 12 coincides with the second module precast wall leaf 12.

[0040] One steel mesh sheet 20 is located in the first module precast wall leaf 11, and the other steel mesh sheet 20 is located in the second module precast wall leaf 12. The rectangular tie bars 30 are respectively connected to the two steel mesh sheets 20.

[0041] A plurality of tie bolts 70 are located between the first module precast wall leaf 11 and the second module precast wall leaf 12. The tie bolts 70 penetrate through the first module precast wall leaf 11 and the second module precast wall leaf 12, and the tie bolts 70 are respectively connected to the first module precast wall leaf 11 and the second module precast wall leaf 12.

[0042] By respectively arranging steel bar meshes in the first module precast wall leaf 11 and the second module precast wall leaf 12, the strength and stability of the first module precast wall leaf 11 and the second module precast wall leaf 12 can be improved. By arranging a plurality of rectangular tie bars 30 between the first module precast wall leaf 11 and the second module precast wall leaf 12, and connecting the rectangular tie bars 30 with the two steel bar meshes 20, when a horizontal force acts on one of the first module precast wall leaf 11 and the second module precast wall leaf 12, a part of the force can be dispersed to the steel bar mesh 20 in the other of the first module precast wall leaf 11 and the second module precast wall leaf 12 through the plurality of rectangular tie bars 30. By arranging a plurality of tension bolts 70, the tension bolts 70 penetrate through the first module precast wall leaf 11 and the second module precast wall leaf 12 and are respectively connected with the first module precast wall leaf 11 and the second module precast wall leaf 12, so that the first module precast wall leaf 11 and the second module precast wall leaf 12 can bear greater horizontal forces, and the first module precast wall leaf 11 and the second module precast wall leaf 12 can be better connected with the concrete poured between the first module precast wall leaf 11 and the second module precast wall leaf 12 to bear the load together, so that the wall body 10 can bear greater forces and has higher structural strength.

[0043] Both the tension bolts 70 and the rectangular tie bars 30 can enhance the structural stability and strength of the in-plane module composite shear wall. Among them, the rectangular tie bars 30 can bear both pressure and thrust. Since they are fixed on the steel bar meshes 20, the main function of the rectangular tie bars 30 is to disperse the force to a larger area and avoid damage to the in-plane module composite shear wall caused by excessive local stress. The tension bolts 70 penetrate through the first module precast wall leaf 11 and the second module precast wall leaf 12, and the tension bolts 70 mainly bear tensile forces, and the forces act directly on the first module precast wall leaf 11 and the second module precast wall leaf 12, avoiding the separation of the first module precast wall leaf 11 and the second module precast wall leaf 12 and maintaining the structural stability of the in-plane module composite shear wall.

[0044] Taking the state after the installation of the in-plane module composite shear wall as an example, the lower edge of the first module precast wall leaf 11 is flush with the lower edge of the second module precast wall leaf 12; the upper edge of the first module precast wall leaf 11 is flush with the upper edge of the second module precast wall leaf 12. The vertical side edges of the first module precast wall leaf 11 and the vertical side edges of the second module precast wall leaf 12 are also flush.

[0045] Both the first-module precast wall panel 11 and the second-module precast wall panel 12 can be precast concrete slabs, for example, precast by a mold. During the preparation of the first-module precast wall panel 11, the steel mesh 20 is placed in the mold in advance. After the concrete poured into the mold solidifies, it forms an integral body with the first-module precast wall panel 11. The preparation method of the second-module precast wall panel 12 can be the same as that of the first-module precast wall panel 11.

[0046] Figure 4 is a schematic structural view of a tie rod provided in an embodiment of the present application. As Figure 4 shown, the tie rod 70 includes a rod body 701, two baffles 702, and two fastening nuts 703. The rod body 701 penetrates through the two baffles 702. The two fastening nuts 703 are sleeved outside the rod body 701, and the two fastening nuts 703 are located outside the two baffles 702. The rod body 701 penetrates through the first-module precast wall panel 11 and the second-module precast wall panel 12. One baffle 702 is located on the side of the first-module precast wall panel 11 away from the second-module precast wall panel 12 and is attached to the first-module precast wall panel 11; the other baffle 702 is located on the side of the second-module precast wall panel 12 away from the first-module precast wall panel 11 and is attached to the second-module precast wall panel 12.

[0047] By tightening the fastening nuts 703, the two fastening nuts 703 are close to each other and pressed against the surface of the baffle 702 to prevent the distance between the first-module precast wall panel 11 and the second-module precast wall panel 12 from expanding, and to ensure the integrity of the in-plane module composite shear wall structure. The baffle 702 plays a role in increasing the contact area and avoiding damage to the surfaces of the first-module precast wall panel 11 and the second-module precast wall panel 12 by the fastening nuts 703.

[0048] As Figure 3 shown, a plurality of rectangular tie bars 30 are distributed in an array. In the horizontal and vertical directions, the rectangular tie bars 30 and the tie rod 70 are alternately distributed.

[0049] In some other possible implementation manners, in the horizontal or vertical direction, the rectangular tie bars 30 and the tie rod 70 are alternately distributed.

[0050] The tie rod 70 and the rectangular tie bars 30 are arranged in an alternating distribution manner, so that the acting forces received by the in-plane module composite shear wall are more dispersed, and the damage to the wall structure caused by excessive acting forces at local positions is avoided.

[0051] As Figure 3 shown, the steel mesh 20 includes a plurality of horizontally arranged horizontal steel bars 21 and a plurality of vertically arranged vertical steel bars 22. The plurality of horizontal steel bars 21 and the plurality of vertical steel bars 22 are cross-arranged into a net shape, and the horizontal steel bars 21 and the vertical steel bars 22 are connected at the intersections.

[0052] For example, the horizontal steel bars 21 and the vertical steel bars 22 may be connected at their intersections by at least one of welding and bundling.

[0053] The steel mesh 20 may include a single layer of steel mesh or a multi-layer steel mesh formed by stacking multiple steel meshes. In the example where the steel mesh 20 includes a single layer of steel mesh, the horizontal steel bar 21 may be a single steel bar, and the vertical steel bar 22 may also be a single steel bar. In the example where the steel mesh 20 includes multiple layers of steel mesh, the horizontal steel bar 21 may include multiple steel bars connected together, and the multiple steel bars in the horizontal steel bar 21 may be welded or tied together. The vertical steel bar 22 may also include multiple steel bars connected together, and the multiple steel bars in the vertical steel bar 22 may be welded or tied together.

[0054] The number of steel meshes included in the steel mesh 20 can be set according to the structural strength requirements of the in-plane modular composite shear wall. Usually, in situations where the structural strength requirements are different, the number of steel meshes included in the steel mesh 20 is larger in the in-plane modular composite shear wall with higher structural strength requirements.

[0055] like Figure 3 As shown, the connection between each rectangular reinforcement 30 and at least one steel mesh 20 is located outside the intersection of the horizontal reinforcement 21 and the vertical reinforcement 22.

[0056] The outer side of the intersection of the horizontal steel bars 21 and the vertical steel bars 22 in one steel mesh 20 refers to the side of the intersection away from the other steel mesh 20.

[0057] Connecting the rectangular tie bars 30 at the intersection of the horizontal steel bars 21 and the vertical steel bars 22 can better disperse the force exerted by the rectangular tie bars 30 on the steel mesh 20 to various parts of the steel mesh 20, which is beneficial to further improve the ability of the in-plane modular composite shear wall to withstand horizontal loads.

[0058] In some examples, the plane where the rectangular tie bars 30 are located is perpendicular to the first module prefabricated wall leaf 11 .

[0059] The first module prefabricated wall leaf 11 and the second module prefabricated wall leaf 12 are arranged in parallel, and the plane where the rectangular tie bars 30 are located can be perpendicular to the first module prefabricated wall leaf 11 and the second module prefabricated wall leaf 12 .

[0060] The rectangular reinforcement 30 may be a steel bar bent into a rectangular frame, and both ends of the steel bar may be connected to form a rectangular frame structure.

[0061] As an example, the rectangular stirrup 30 may include a single steel bar bent into a rectangular frame, or may include a plurality of steel bars bent into rectangular frames and stacked. In the example where the rectangular stirrup 30 includes a plurality of steel bars bent into rectangular frames and stacked, the plurality of steel bars bent into rectangular frames may be welded or tied together.

[0062] The plane where the rectangular stirrup 30 is located is perpendicular to the first modular precast wall panel 11 and the second modular precast wall panel 12, so that during the process of the in-plane modular composite shear wall bearing horizontal loads, the acting force of the rectangular stirrup 30 on the first modular precast wall panel 11 and the second modular precast wall panel 12 is perpendicular to the first modular precast wall panel 11 and the second modular precast wall panel 12.

[0063] As Figure 3 shown, in some examples, the plane where the rectangular stirrup 30 is located is perpendicular to the horizontal steel bar 21. The same rectangular stirrup 30 is coplanar and connected to one vertical steel bar 22 in each of the two steel mesh sheets 20. That is, the rectangular stirrup 30 is arranged vertically.

[0064] As another example, the plane where the rectangular stirrup 30 is located is perpendicular to the vertical steel bar 22. That is, the rectangular stirrup 30 is arranged horizontally.

[0065] That is to say, the rectangular stirrup 30 can be placed horizontally or vertically. When the rectangular stirrup 30 is placed vertically and horizontally, there will be certain differences in the mechanical properties of the in-plane modular composite shear wall. For example, there are certain differences in terms of bending resistance and torsion resistance. The appropriate arrangement method can be selected according to different occasions.

[0066] Figure 5 is a partial structural schematic diagram of a wall body provided by an embodiment of the present application. In this example, the rectangular stirrup 30 is arranged horizontally. As Figure 5 shown, the same rectangular stirrup 30 is connected to one horizontal steel bar 21 in each of the two steel mesh sheets 20.

[0067] The horizontal steel bars 21 in the two steel mesh sheets 20 are all arranged horizontally. The same rectangular stirrup 30 and one horizontal steel bar 21 in each of the two steel mesh sheets 20 can all be coplanar. That is to say, the two horizontal steel bars 21 connected to the same rectangular stirrup 30 are arranged at the same height. One side of the rectangular stirrup 30 can be overlapped and connected with one of the horizontal steel bars 21, and the other side of the rectangular stirrup 30 can be overlapped and connected with the other horizontal steel bar 21. This is beneficial to form a larger range of connection between the rectangular stirrup 30 and the steel mesh sheet 20, thereby further improving the structural stability and strength of the in-plane modular composite shear wall.

[0068] In some examples, the rectangular stirrup 30 is at least sleeved outside two adjacent vertical steel bars 22 in one steel mesh sheet 20.

[0069] In this example, a part of the rectangular stirrups 30 are sleeved outside the vertical steel bars 22 of the steel mesh 20 located in the precast wall leaf 11 of the first module, and another part of the rectangular stirrups 30 are sleeved outside the vertical steel bars 22 of the steel mesh 20 located in the precast wall leaf 12 of the second module.

[0070] Sleeving the rectangular stirrups 30 outside the vertical steel bars 22 enables the rectangular stirrups 30 to exert a large tensile force on the steel mesh 20 without damaging the connection.

[0071] Figure 6 It is a schematic diagram of a partial structure of a wall body provided by an embodiment of the present application, as Figure 6 shown. In this example, the multiple rectangular stirrups 30 include a first rectangular stirrup 301 and a second rectangular stirrup 302. The first rectangular stirrup 301 is a rectangular stirrup 30 sleeved outside two adjacent vertical steel bars 22 in one steel mesh 20, and the second rectangular stirrup 302 is a rectangular stirrup 30 sleeved outside two adjacent vertical steel bars 22 in another steel mesh 20.

[0072] By sleeving a part of the rectangular stirrups 30 outside the vertical steel bars 22 of the steel mesh 20 located in the precast wall leaf 11 of the first module and another part of the rectangular stirrups 30 outside the vertical steel bars 22 of the steel mesh 20 located in the precast wall leaf 12 of the second module, no matter the in-plane modular composite shear wall is subjected to a force from the precast wall leaf 11 of the first module to the precast wall leaf 12 of the second module or a force from the precast wall leaf 12 of the second module to the precast wall leaf 11 of the first module, there is always a part of the rectangular stirrups 30 that can bear a large tensile force.

[0073] As an example, one side of the first rectangular stirrup 301 and one side of the second rectangular stirrup 302 at least partially overlap and are connected.

[0074] By making one side of the first rectangular stirrup 301 partially overlap and connect with one side of the second rectangular stirrup 302, when the in-plane modular composite shear wall bears a horizontal force, the precast wall leaf 11 of the first module and the precast wall leaf 12 of the second module can better transfer the force through the rectangular stirrups 30, making the force more dispersed and improving the stability of the in-plane modular composite shear wall.

[0075] Figure 6 In the shown example, one side of the first rectangular stirrup 301 completely overlaps and is connected with one side of the second rectangular stirrup 302, which can further improve the stability of the double-sheet shear wall.

[0076] Figure 7 It is a schematic diagram of a partial structure of a wall body provided by an embodiment of the present application, as Figure 7As shown, one side of the rectangular stirrup 30 is connected with a bent portion, and the bent portion is located on one side where two rectangular stirrups 30 at least partially overlap, and the bent portions of the two rectangular stirrups 30 are cross-connected. The wall body further includes connecting bars 23, and the connecting bars 23 are inserted into the space formed by the bent portion and the rectangular stirrup 30.

[0077] In this example, one side of the first rectangular stirrup 301 is connected with a first bent portion 303, one side of the second rectangular stirrup 302 is connected with a second bent portion 304, and the first bent portion 303 and the second bent portion 304 are cross-connected. The overlapping part of the first rectangular stirrup 301 and the second rectangular stirrup 302, the first bent portion 303, and the second bent portion 304 enclose a triangular space, and the connecting bar 23 is inserted into this triangular space. The connecting bar 23 can also be respectively connected with the first bent portion 303 and the second bent portion 304. In Figure 7 the shown example, the rectangular stirrups 30 are horizontally arranged, the connecting bars 23 can be parallel to the vertical steel bars 22, and the connecting bars 23 can be inserted into multiple triangular spaces arranged collinearly to further enhance the structural strength and stability of the wall body.

[0078] In other possible implementation manners, the rectangular stirrups 30 can also be vertically arranged, and the connecting bars 23 are parallel to the horizontal steel bars 21.

[0079] As Figure 3 shown, the in-plane modular superposed shear wall further includes a plurality of loop-shaped connecting bars 42. Figure 8 is a structural schematic diagram of a floor slab and a loop-shaped connecting bar provided by an embodiment of the present application. As Figure 8 shown, the loop-shaped connecting bars 42 are arranged along the height direction of the wall body 10, and the middle parts of the plurality of loop-shaped connecting bars 42 are respectively connected with the floor slab 41. The floor slab 41 can be the top plates of two adjacent lower concrete modular boxes. The top plates of two adjacent lower concrete modular boxes form an integral body during the pouring process, that is, the floor slab 41.

[0080] One end of the loop-shaped connecting bar 42 is located between the first precast wall leaf 11 and the second precast wall leaf 12 of the module, and the other end of the loop-shaped connecting bar 42 extends out of the edges of the first precast wall leaf 11 and the second precast wall leaf 12 of the module.

[0081] During construction, different in-plane modular superposed shear walls will be connected. For example, the in-plane modular superposed shear wall located in the middle layer of the building will be connected with the adjacent lower in-plane modular superposed shear wall and the adjacent upper in-plane modular superposed shear wall. A plurality of loop-shaped connecting bars 42 are used to connect the wall bodies 10 of adjacent in-plane modular superposed shear walls into an integral body.

[0082] As an example, during on-site construction, for the in-plane modular composite shear walls of adjacent two floors, one end of the loop-shaped connecting bars 42 of the upper in-plane modular composite shear wall that extend out of the edges of the first precast wall leaf 11 and the second precast wall leaf 12 is inserted into the wall body 10 of the lower layer. In the lower in-plane modular composite shear wall, after the concrete between the first precast wall leaf 11 and the second precast wall leaf 12 is poured and cured, the loop-shaped connecting bars 42 are fixed in the wall body 10 of the lower layer. Then, the concrete is poured between the first precast wall leaf 11 and the second precast wall leaf 12 of the upper in-plane modular composite shear wall.

[0083] In some examples, the in-plane modular composite shear wall further includes connecting core columns, which can be located at the edge positions of the wall body 10 and arranged along the height direction of the wall body 10. One end of the connecting core column is located between the first precast wall leaf 11 and the second precast wall leaf 12, and the other end extends out of the edges of the first precast wall leaf 11 and the second precast wall leaf 12. When splicing adjacent in-plane modular composite shear walls, one end of the connecting core column that extends out of the edges of the first precast wall leaf 11 and the second precast wall leaf 12 is used to be inserted into the wall body 10 of the lower in-plane modular composite shear wall.

[0084] Exemplarily, the connecting core column can be a rectangular steel structure member.
