[0002] Prefabricated buildings have become an important direction for achieving green buildings and industrialization due to their short construction period and clean and environmentally friendly construction sites. Among them, modular buildings have become the mainstream direction of future development with their advantages of highly integrated decoration and electromechanical pipelines. Currently, modular buildings mainly include steel structure modular buildings and concrete modular buildings. Concrete modular building structures have price advantages and have become the mainstream development direction.

[0003] In modular shear wall buildings, due to the overlap of anchor steel bars in modular building shear walls, a vertical drop installation process is used during installation. This makes it difficult to handle the vertical joints of shear walls between different modules. A common practice is to tie steel bars on site and support formwork for partial concrete pouring. This method can ensure the reliability of the vertical connection of the shear wall, but some formwork still needs to be retained on site, which is contrary to the concept of modular building with less on-site work.

[0057] The present invention will be further described in detail below in conjunction with the accompanying drawings and examples. It is particularly noted that the following examples are only used to illustrate the present invention, but are not intended to limit the scope of the present invention. Similarly, the following examples are only partial embodiments of the present invention rather than all embodiments, and all other embodiments obtained by those of ordinary skill in the art without creative work are within the scope of protection of the present invention.

[0058] The present invention provides a steel lock plate connection node based on a modular shear wall structure, which can realize a formwork-free construction process, can solve the vertical connection problem of shear walls between modules, and has sufficient shear resistance and energy dissipation effect.

[0059] See also Figure 1 and Figure 2In a first aspect, the present embodiment provides a steel locking plate connection node 1, comprising an embedded plate 11, a steel locking plate assembly, a first anchor bar group 14 and a second anchor bar group 15. The embedded plate 11 has a first side surface and a second side surface which are arranged opposite to each other; the steel locking plate assembly is arranged on the first side surface of the embedded plate 11, and the steel locking plate assembly includes a first plate 12, a second plate 13, an anchor hole 121 and an interlocking cavity 122, the first plate 12 is vertically arranged on the embedded plate 11, and the first plate 12 is arranged between the embedded plate 11 and the second plate 13 to form the interlocking cavity 122, the first plate 12 is perpendicular to the second plate 13, and the first plate 12 is provided with an anchor hole 121; the first anchor bar group 14 is arranged on the second side surface of the embedded plate 11, the first anchor bar group 14 includes a plurality of first anchor bars, and the plurality of first anchor bars are distributed on the second side surface at intervals in the vertical direction; the second anchor bar group 15 is arranged on the second side surface of the embedded plate 11, the second anchor bar group 15 is arranged opposite to the first anchor bar group 14, the second anchor bar group 15 includes a plurality of second anchor bars, and the plurality of second anchor bars are distributed on the second side surface at intervals in the vertical direction, and the first anchor bars and the second anchor bars which are placed at the same height are arranged opposite to each other.

[0060] In this embodiment, the embedded plate 11 refers to a metal plate pre-embedded in concrete for subsequent connection with other steel structures, namely, the first plate 12, the second plate 13, the first anchor bar group 14 and the second anchor bar group 15; the first plate 12 and the second plate 13 are two main components in the steel locking plate assembly, which are arranged vertically to form a U-shaped structure with the embedded plate 11, namely, a fitting cavity. Anchor holes 121 are provided on the first plate 12, and the anchor holes 121 are used for the subsequent fixing process of the anchor rod 5, as described below. It can be understood that the anchor holes 121 can be arranged close to one side of the second plate 13 for easy splicing. The provision of the anchor holes 121 allows the anchor rod 5 to be easily installed and fixed, simplifying the construction process.

[0061] The first anchor bar group 14 and the second anchor bar group 15 are distributed at intervals along the vertical direction on the other side of the embedded plate. For the convenience of distinction, the two sides of the embedded plate 11 are recorded as the first side and the second side. The first plate 12 and the second plate 13 are distributed on the first side, and the first anchor bar group 14 and the second anchor bar group 15 are distributed on the second side and are arranged opposite to each other. Specifically, the first anchor bar group 14 includes a plurality of first anchor bars, and the first anchor bars are distributed at intervals along the vertical direction on the second side, such as Figure 1 and Figure 2 As shown, the second anchor bar group 15 includes a plurality of second anchor bars, and the second anchor bars are distributed at intervals on the second side surface along the vertical direction. Figure 1 and Figure 2 As shown, it can be understood that the first anchor bar and the second anchor bar can be set in one-to-one correspondence based on the set height, so that the uniform distribution of the anchoring force can be achieved and the anchoring performance of the overall structure can be improved.

[0062] When in use, the first anchor bar group 14, the second anchor bar group 15 and the embedded plate 11 are all pre-embedded in the shear wall structure 2. After pouring concrete to form the double wall described later, the steel locking plate assembly can be directly fixed in the building gap of the shear wall structure 2 to facilitate further splicing and use.

[0063] In this embodiment, the first anchor bar group 14 is configured to be embedded in the first double skin wall 21 at a first preset depth; the second anchor bar group 15 is configured to be embedded in the second double skin wall 22 at a second preset depth. By arranging the first anchor bar group 14 and the second anchor bar group 15 on the embedded plate, stress can be dispersed, thereby improving the durability and service life of the structure; it has sufficient shear resistance and energy dissipation, takes into account the transmission and distribution of force, reduces the risk of structural failure, and improves the safety of the overall structure. It is convenient to realize the construction process of the shear wall in the splicing process without formwork, which is in line with the concept of less work on the modular building site.

[0064] See also Figure 1 and Figure 2 In this embodiment, the first plate 12 is eccentrically disposed on the embedded plate 11 , and the anchor hole 121 is disposed close to the second plate 13 .

[0065] In this embodiment, the eccentric setting of the first plate 12 can keep the center of gravity of the entire steel lock plate connection node 1 at the geometric center, which can improve the connection strength of the entire steel lock plate connection node 1. At the same time, the eccentric setting of the first plate 12 is convenient for the subsequent splicing of two steel lock plate connection nodes 1. The middle interlocking cavity can have a larger area overlap to pour concrete and ensure the stress strength of the two steel lock plate connection nodes 1 after pouring. By arranging the first plate 12 and the second plate 13 on the embedded plate 11 and forming the interlocking cavity 122, such a structural design can provide better mechanical stability and bearing capacity when bearing vertical and horizontal loads.

[0066] In this embodiment, the anchor hole 121 is arranged close to the second plate 13. When the two steel lock plate connection nodes 1 are subsequently spliced, the space area occupied by the anchor rod 5 connection can be reduced, and the steel lock plate connection node 1 can be placed as much as possible between the building gap enclosed by the first double skin wall 21 and the second double skin wall 22, thereby improving the connection strength when the two shear wall structures 2 are spliced, and reducing the influence of the vertical connection node 61 at the connection point on the overall connection structure.

[0067] See also Figure 1 In this embodiment, the first plate 12 has a first extension length; the first anchor bar has a first length, which is greater than the first extension length; the second anchor bar has a second length, which is greater than the first extension length.

[0068] In this embodiment, the first extension length can be understood as the distance between the second plate 13 and the first side of the embedded plate 11, the first length of the first anchor bar can be understood as the distance between the free end of the first anchor bar and the second side of the embedded plate 11, and similarly, the second length of the second anchor bar can be understood as the distance between the free end of the second anchor bar and the second side of the embedded plate 11, and the first anchor bar and the second anchor bar can have the same length. In this embodiment, by setting the first length of the first anchor bar and the second length of the second anchor bar to be greater than the first extension length of the first plate 12, the first anchor bar and the second anchor bar can provide sufficient tensile strength to the first plate 12 and the second plate 13, thereby avoiding the rollover problem of the first plate 12 and the second plate 13 on the embedded plate 11, thereby improving the anchoring force and making the connection more secure. During the construction process, the first length of the first anchor bar and the second length of the second anchor bar can be adjusted according to the actual structural conditions to ensure the best anchoring effect and improve the flexibility of construction.

[0069] See also Figures 3 to 6 In a second aspect, the present invention provides a shear wall structure 2, comprising a first double wall 21 and a second double wall 22. The second double wall 22 is arranged in parallel with the first double wall 21, and there is a building gap to be filled between the first double wall 21 and the second double wall 22; a plurality of steel lock plate connection nodes 1 are arranged in the building gap at intervals along the extension direction of the first double wall 21, and the steel lock plate connection nodes 1 are the steel lock plate connection nodes 1 described in the first aspect.

[0070] In this embodiment, the first double wall 21 and the second double wall 22 are two parallel walls in the shear wall structure 2, with a building gap in the middle to be filled with concrete. A plurality of steel locking plate connection nodes 1 are arranged at intervals in the building gap along the extension direction of the first double wall 21 to achieve effective connection between the double walls, thereby improving the overall stability and bearing capacity of the shear wall.

[0071] Specifically, the first double skin wall 21 and the second double skin wall 22 can be made by laying steel bars and reinforcement cages, and then pouring concrete or other building materials, such as Figures 3 to 6 , showing the manufacturing process of the first double skin wall 21, the second double skin wall 22 and the steel lock plate connection node 1. It should be noted that in this process, there is a building gap between the first double skin wall 21 and the second double skin wall 22, and the building gap is used for the subsequent shear wall manufacturing.

[0072] In this embodiment, the embedded plate 11, the first anchor bar group 14, and the second anchor bar group 15 are all arranged at a certain distance inside the edges of the first double skin wall 21 and the second double skin wall 22, and part of the structure of the first plate 12 protrudes out of the edges of the first double skin wall 21 and the second double skin wall 22 to facilitate the anchor hole 121 to protrude to the outside, and the second plate 13 is completely placed outside the edges of the first double skin wall 21 and the second double skin wall 22, thus forming a structure in which part of the mosaic cavity protrudes out, which is convenient for the subsequent splicing of the two shear wall structures 2.

[0073] See also Figure 1 and Figure 5 In some embodiments, the first anchor bar group 14 is configured to be pre-buried in the first double skin wall 21 at a first preset depth; the second anchor bar group 15 is configured to be pre-buried in the second double skin wall 22 at a second preset depth; the first plate 12 is configured to protrude a preset distance from the outer edge of the first double skin wall 21 so that the anchor hole 121 is placed outside the first double skin wall 21.

[0074] In this embodiment, the first anchor bar group 14 can be pre-buried at a first preset depth in the first double skin wall 21, and the second anchor bar group 15 can be pre-buried at a second preset depth in the second double skin wall 22, wherein the first preset depth and the second preset depth are adjusted according to actual needs, thereby improving the flexibility of the structural design; the first plate 12 is designed to protrude a preset distance from the outer edge of the first double skin wall 21, so that the anchor hole 121 is located outside the first double skin wall 21, which helps to fix the anchor rod 5.

[0075] See also Figures 7 to 9 In a third aspect, the present embodiment provides a shear wall, which includes a first shear wall 3 and a second shear wall 4. The first shear wall 3 is the shear wall structure 2 of the second aspect, and the first shear wall 3 has a first steel locking plate connection node 31, and the first steel locking plate connection node 31 has a first interlocking cavity; the second shear wall 4 is the shear wall structure 2 of the second aspect, and the second shear wall 4 has a second steel locking plate connection node 41, and the second steel locking plate connection node 41 has a second interlocking cavity; the first shear wall 3 and the second shear wall 4 are configured to be nested and connected through the first steel locking plate connection node 31 and the second steel locking plate connection node 41, and the first interlocking cavity and the second interlocking cavity at least partially overlap.

[0076] In this embodiment, the shear wall is also called a wind-resistant wall or an earthquake-resistant wall or a structural wall. It is a wall in a house or structure that mainly bears horizontal loads caused by wind loads or earthquakes, and is usually a reinforced concrete structure. In this embodiment, the specific structural form of how two shear walls are assembled into one shear wall is shown, and the fourth aspect describes a specific method of how two shear walls are assembled into one shear wall.

[0077] For ease of description, in this embodiment, the two shear walls are respectively recorded as the first shear wall 3 and the second shear wall 4, wherein the first shear wall 3 and the second shear wall 4 both refer to the shear wall structure 2 described in the second aspect. The first shear wall 3 and the second shear wall 4 are connected by a first steel locking plate connection node 31 and a second steel locking plate connection node 41. The specific connecting structure can be combined with Figure 2 , Figures 7 to 9 For understanding, further interlocking methods can be understood by referring to the fourth aspect described later. For ease of expression, the interlocking cavity of the first steel lock plate connection node 31 is recorded as the first interlocking cavity, and the interlocking cavity of the second steel lock plate connection node 41 is recorded as the second interlocking cavity. The first interlocking cavity and the second interlocking cavity are partially overlapped by interlocking the first steel lock plate connection node 31 and the second steel lock plate connection node 41. The partial overlap of the first interlocking cavity and the second interlocking cavity can make the concrete be poured to the overlapping area of ​​the first interlocking cavity and the second interlocking cavity simultaneously during the process of pouring the first shear wall 3 and the second shear wall 4, so that the first shear wall 3 and the second shear wall 4 can be connected. The force wall 4 is fused into a whole. During this process, the engagement of the first steel locking plate connection node 31 and the second steel locking plate connection node 41 can provide rigid connection and support for the first shear wall 3 and the second shear wall 4, thereby improving the structural stiffness and stability of the vertical connection node 61. At the same time, the first steel locking plate connection node 31 and the second steel locking plate connection node 41 can also provide vertical guidance for the first shear wall 3 and the second shear wall 4 during the splicing process, avoiding displacement during the splicing process, and facilitating the splicing process of the first shear wall 3 and the second shear wall 4.

[0078] In this embodiment, the first steel lock plate connection node 31 and the second steel lock plate connection node 41 are nested and connected, so that the first embedding cavity and the second embedding cavity at least partially overlap. The nested connection method simplifies the construction process and reduces the workload of on-site welding or bolt connection. At the same time, the vertical connection node 61 formed has a good bearing capacity, has better integrity, and improves overall neatness and aesthetics.

[0079] See also Figure 7 and Figure 8 In this embodiment, the first steel locking plate connection node 31 has a first anchor hole, the second steel locking plate connection node 41 has a second anchor hole, and the shear wall structure 2 also includes an anchor rod group, which includes a plurality of anchor rods 5, and each anchor rod 5 sequentially penetrates the first anchor hole and the second anchor hole arranged at the same height.

[0080] For ease of description, the anchor hole of the first steel lock plate connection node 31 is recorded as the first anchor hole, and the anchor hole of the second steel lock plate connection node 41 is recorded as the second anchor hole. The first anchor hole and the second anchor hole are coaxial when the first and second fitting cavities are fitted together. Figure 7 and Figure 8As shown, the anchor rod 5 can pass through the first anchor bolt hole and the second anchor bolt hole to keep the first steel locking plate connection node 31 and the second steel locking plate connection node 41 relatively fixed in the vertical direction.

[0081] In this embodiment, the anchor rod 5 is a component in an engineering structure, which is mainly used to fix soil or rock to increase the stability of the structure. The anchor rod 5 can be a solid steel rod or other rods, which are specifically set according to actual needs. The anchor rod group includes a plurality of anchor rods 5, each anchor rod 5 corresponds to a first anchor hole and a second anchor hole at the same height, and each anchor rod 5 in the anchor rod group can play a role in fixing and reinforcing. After the first shear wall 3 and the second shear wall 4 are nested and connected, the two are further spliced ​​together to form a whole through the anchor rod group, which significantly enhances the connection strength between the first shear wall 3 and the second shear wall 4, and improves the overall stability and bearing capacity of the structure.

[0082] See also Figures 3 to 7 In a fourth aspect, the present invention provides a shear wall installation method, which is applicable to the shear wall of the third aspect, wherein the first shear wall has a first building gap, and the second shear wall has a second building gap, and the shear wall installation method comprises:

[0083] Placing the first shear wall at a first preset position along the vertical direction so that the first engaging cavity is opened toward the first direction a;

[0084] Move the second shear wall from top to bottom in the vertical direction to a second preset position, so that the second steel lock plate connection node is nested at the first steel lock plate connection node, the second embedding cavity is opened toward the second direction b, the second direction b is opposite to the first direction a, and the first embedding cavity and the second embedding cavity at least partially overlap;

[0085] Concrete is filled into the first building gap, the second building gap, the first embedding cavity and the second embedding cavity to obtain a shear wall.

[0086] In this embodiment, the first shear wall 3 and the second shear wall 4 are both the shear wall structures described in the second aspect. Based on this, the first shear wall 3 has a building void and the second shear wall 4 has a building void. For ease of distinction, the building void of the first shear wall 3 is recorded as the first building void 32, and the building void of the second shear wall 4 is recorded as the second building void 42.

[0087] Specifically, the first shear wall 3 is placed in a first preset position along the vertical direction. The first preset position is an area reserved in advance for constructing the shear wall. This step requires ensuring that the first shear wall 3 remains arranged in the vertical direction so that the first interlocking cavity is opened toward the first direction a.

[0088] Similarly, the second shear wall 4 is placed in the second preset position along the vertical direction. The second preset position is adjacent to the first preset position. During the placement process, the second shear wall 4 needs to be lowered in a top-down manner so that the opening of the second fitting cavity faces the second direction b, and the first steel lock plate connection node 31 and the second steel lock plate connection node 41 form Figure 7 The chimeric structure shown.

[0089] On this basis, concrete is filled into the first building void 32, the second building void 42, the first interlocking cavity and the second interlocking cavity, and after necessary curing processes, a complete shear wall can be obtained.

[0090] The steps shown in this embodiment can realize the simple installation of the first shear wall 3 and the second shear wall 4 on site, minimize the difficulty and steps of assembling the shear walls on site, and at the same time ensure the structural rigidity and stability of the first shear wall 3 and the second shear wall 4 after assembly.
