TECHNICAL FIELD

[0001] The utility model relates to the technical field of building construction, especially to a wall shell for a composite shear wall and a composite shear wall. BACKGROUND

[0002] With the continuous advancement of traditional building industry leading to ecological environment pollution, overconsumption of resources and other problems are becoming increasingly serious, therefore, the fabricated building industry with environmental protection, high efficiency, energy saving and sustainable development emerges as the times require. The traditional fabricated building mainly refers to the assembled monolithic building, that is, the building with part of the components prefabricated and assembled, key components and connecting nodes cast in situ, which improves the construction efficiency without losing the structural mechanical properties, ensuring the building function and structural safety. In recent years, with the wide application of intelligent construction technology of industrialization and informationization in the construction industry, the traditional structure construction method has undergone innovative transformation, and a higher degree of modular building system has gradually formed. Modular building is the latest achievement of the highly developed prefabricated building industry. The characteristic of this building system is that the basic unit of construction is no longer a wall, a board, a beam or other structural components, but a three-dimensional module unit in the form of split building space. The three-dimensional module unit is manufactured in the factory, transported to the site, and connected to form a whole building. The advantage is that indoor decoration and mechanical and electrical water heating integration can be completed in the factory, reducing the number of components assembled on site, greatly improving the prefabrication efficiency, shortening the construction period and achieving higher construction quality.

[0003] In the prior art, Chinese patent CN116335316A proposes a composite shear wall with interlocking structure and its construction method. The composite shear wall comprises: a prefabricated wall A module, a prefabricated wall B module, and a horizontal hoop. The prefabricated wall A module is provided with a rib, and correspondingly, the prefabricated wall B module is provided with a hole matched with the rib. When the prefabricated wall A module and the prefabricated wall B module are overlapped, the rib penetrates into the hole to complete interlocking, and the gap between the prefabricated wall A module and the prefabricated wall B module is set as a grouting area. The prefabricated wall A module is pre-buried with shear wall vertical reinforcement one, and correspondingly, the prefabricated wall B module is pre-buried with shear wall vertical reinforcement two opposite to the shear wall vertical reinforcement one. The horizontal hoop is arranged at one end of the shear wall vertical reinforcement one and at the other end of the shear wall vertical reinforcement two.

[0004] Chinese patent CN218933525U proposes a disassembly-free concrete module wall mold, which is applied between two adjacent module units and comprises a first wall mold and a second wall mold. The first wall mold is provided with a truss rib, and the truss rib is provided with a counter-pulling device for counter-pulling the first wall mold and the second wall mold. A pouring cavity is formed between the first wall mold and the second wall mold.

[0005] Therefore, there are the following problems: 1, the interlocking structure process between the prefabricated wall A module and the prefabricated wall B module is relatively complex, and it is difficult to manufacture in the factory; 2, the connection mechanical property between the prefabricated wall A module and the prefabricated wall B module is low, and it is difficult to ensure the reliability of the overall structure; 3, the demolition-free concrete module wall mold is used for the pulling device between the modules, which destroys the indoor decoration.

[0034] In order to better explain the utility model, so as to facilitate understanding, the utility model is described in detail below by specific implementation mode, combined with drawings.

[0035] Embodiment 1:

[0036] Refer to Figure 1 And Figure 2The embodiment provides a wall shell for a composite shear wall, which is a side wall shell of a building module and is used to form a composite shear wall for connecting two building modules when the two building modules are adjacent. Specifically, the wall shell for a composite shear wall comprises a concrete wall body 1 and an embedded plate 2 fixed to the concrete wall body 1, as described below in detail.

[0037] The embedded plate 2 in the embodiment comprises a plate body 21, a plurality of first welding nails 22 welded on the outer side of the plate body 21, and a plurality of second welding nails 23 welded on the inner side of the plate body 21. The inner side of the plate body 21 is a surface facing the concrete wall body 1, and the outer side of the plate body 21 is a surface away from the concrete wall body 1.

[0038] The first welding nails 22 and the second welding nails 23 respectively extend inward and outward based on the plate body 21, the head of the first welding nail 22 is away from the plate body 21, and the head of the second welding nail 23 is also away from the plate body 21.

[0039] The inner side of the plate body 21 of the embedded plate 2 is parallel to and abuts against the concrete wall body 1, the second welding nails 23 are pre-buried in the concrete wall body 1, and the outer side of the embedded plate 2 is the outer side of a wall shell. The plurality of second welding nails 23 can enhance the strength of the concrete wall body 1 itself and the connection strength between the embedded plate 2 and the concrete wall body 1, the surface area of the head of the second welding nail 23 is greater than the cross-sectional area of the middle of the second welding nail 23, so that the connection area between the second welding nail 23 and the concrete wall body 1 can be increased, the second welding nail 23 and the concrete wall body 1 form an anchoring relationship, and the connection strength between the embedded plate 2 and the concrete wall body 1 is improved.

[0040] When two wall shells for a composite shear wall are arranged adjacently, the surfaces of the opposite concrete wall bodies 1 are both embedded plates 2, a pouring space is formed between the outer sides of the plate bodies 21 of the two embedded plates 2, the first welding nails 22 extend into the pouring space and are spaced apart from the plate body 21 of the opposite wall shell, so that the first welding nails 22 of the two embedded plates 2 can form an anchoring connection with the post-poured concrete in the pouring space and be in a state of opposite pulling. The embedded plate 2 replaces the original steel reinforcement cage, and the first welding nail 22 can form an anchoring relationship with the post-poured concrete.

[0041] In summary, compared with the prior art, the embedded plate 2 increases the in-plane and out-of-plane stiffness of the composite shear wall, replaces the original steel mesh of the form shell part and the steel reinforcement cage in the cast-in-place part of the composite shear wall, and when the concrete is poured, the first welding nails 22 of the adjacent embedded plates 2 form an anchoring connection with the post-poured concrete in the pouring space, realizes a strong connection of the normal opposite pulling, the tangential shear resistance and the in-plane bending resistance of the wall shells of the two composite shear walls, has a simple structure, and improves the integrity of indoor decoration.

[0042] Preferably, the first welding studs 22 on the plate body 1 are arranged in a matrix, and the distance between adjacent first welding studs 22 is in the range of 250-350 mm.

[0043] Preferably, the second welding studs 23 on the plate body 1 are arranged in a matrix, and the distance between adjacent second welding studs 23 is in the range of 350-450 mm, and the distance between adjacent second welding studs 23 is greater than the distance between adjacent first welding studs 22.

[0044] Specifically, the above-mentioned "matrix" is that a plurality of first welding studs 22 are arranged in rows in the transverse direction and in columns in the vertical direction, so that four first welding studs 22 in two adjacent rows and two adjacent columns form a rectangle, and the second welding studs 23 are in the same case as the first welding studs 22, and the second welding studs 23 are sparser than the first welding studs 22. Specifically, the matrix arrangement can effectively disperse external loads, ensure that the loads are evenly distributed on the first welding studs 22 and the second welding studs 23, reduce the risk of single-point overload, and simplify the construction positioning steps, reduce the dependence on workers' experience, provide quantitative basis for construction, optimize the amount of materials, and improve the anti-deformation ability and connection strength. The staggered arrangement of the first welding studs 22 and the second welding studs 23 can better disperse and transfer loads, thereby improving the stability of the entire wall shell for the composite shear wall, the first welding studs 22 can also provide support in different directions, increase the load-bearing capacity of the structure, and help resist torsional forces. At the same time, the phenomenon of local stress concentration caused by the concentrated arrangement of the first welding studs 22 is avoided, and the risk of damage to the connecting structure is reduced.

[0045] Preferably, the length of the second welding stud 23 is in the range of 30-40 mm, and the thickness of the plate body 21 is in the range of 4-10 mm. The second welding stud 23 needs to be inserted into the concrete wall 1, and the thickness of the concrete wall 1 is in the range of 30-40 mm, so the length range of the second welding stud 23 should also be so, and the thickness of the embedded plate 2 can improve the strength and stiffness of the embedded plate 2, so when facing different thicknesses of composite shear walls, different thicknesses of embedded plates 2 in the range of 4-10 mm need to be used.

[0046] Preferably, the material of the plate body 21 is steel. In order to significantly improve the stiffness of the embedded plate 2 and take into account the cost, steel is a better choice, and when using welding studs, it is also convenient to connect with steel.

[0047] Of course, the fixing method of the embedded plate 2 and the same side concrete wall 1 is not limited to the pre-buried method of the second welding stud, and the embedded plate 2 can also be fixed and connected with the concrete wall 1 through other structures, such as screwing or clamping. Of course, the structure of using welding studs on both sides of the embedded plate 2 in the present embodiment is more conducive to manufacturing.

[0048] Referring to Figure 3 and Figure 4The utility model provides a kind of superimposed shear wall, including two for the wall shell of superimposed shear wall;Two wall shells are adjacently arranged and form pouring space between its plate body 21, first rivet 22 extends into pouring space and is spaced apart with the plate body 21 of opposite wall shell, and concrete wallboard 3 is formed by pouring between two embedded plates 2;First rivet 22 of two side embedded plates 2 is staggered arrangement with each other, and forms anchoring connection with concrete wallboard 3, and is in the state of being pulled apart.The two spaced apart concrete wall 1 and the outer formwork fixedly connected on the both sides of concrete wall 1 form pouring space, replace the reinforcement cage in traditional superimposed shear wall with embedded plate 2, save original reinforcement cage, and first rivet 22 can form strong connection between concrete and the end of first rivet 22 with large surface area, therefore, the stability of the superimposed shear wall is better.

[0049] In summary, compared with prior art, the internal concrete wallboard 3 of the superimposed shear wall is engaged with the first rivet 22 and the second rivet 23 on both sides, which improves the buckling prevention effect of the embedded plate 2 and enhances the integrity, bending resistance, tensile and compressive resistance and shear capacity of the superimposed shear wall.

[0050] Preferably, the superimposed shear wall is composed of two concrete walls 1, two embedded plates 2 and a concrete wallboard 3. By using only two concrete walls 1, two embedded plates 2 and a concrete wallboard 3 to form the superimposed shear wall, strong connection can be formed with a simple structure, saving labor and accelerating progress.

[0051] Preferably, the thickness of the concrete wallboard 3 is within the range of 100-300 mm. The head of the first rivet 22 needs to be anchored with concrete, and the width of all concrete wallboards 3 is not consistent. Therefore, the length of the first rivet 22 is less than the width of the concrete wallboard 3, so that the first rivet 22 can extend into the concrete wallboard 3.

[0052] Preferably, when the superimposed shear wall is a single limb wall, the number of embedded plates 2 on one concrete wall 1 is one; when the superimposed shear wall is a multiple limb wall, the number of embedded plates 2 on one concrete wall 1 is equal to the number of wall limbs. When the superimposed shear wall is a single limb wall, only one embedded plate 2 is needed for the entire superimposed shear wall without opening holes on the wall. When the superimposed shear wall needs to have openings, it is a multiple limb wall, and the entire embedded plate 2 cannot be used. Therefore, the number of embedded plates 2 is equal to the number of wall limbs.

[0053] Example 2:

[0054] Reference Figure 5The difference between the embodiment and embodiment 1 is that the arrangement forms of the first welding pegs 22 and the second welding pegs 23 are different, specifically, the plurality of first welding pegs 22 are arranged in a quincunx shape, the distance between adjacent first welding pegs 22 is in the range of 140-160mm; the plurality of second welding pegs 23 are arranged in a quincunx shape, the distance between adjacent second welding pegs 23 is in the range of 140-160mm. The quincunx arrangement improves the structural stability and bearing capacity, and compared with the matrix arrangement, the quincunx arrangement has better anti-seismic performance and higher density.
