Description

Technical Field

[0001] This invention patent relates to the field of modular building construction, and in particular to a steel lock plate connection node, a shear wall structure, a shear wall and its installation method. Background Technology

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

[0003] In modular shear wall buildings, the installation process often involves a vertical drop due to the lap splicing of anchoring reinforcement in the shear walls. This makes the vertical joint connections between different modules quite difficult. A common practice is to tie the reinforcement on-site and then pour concrete locally using formwork. While this method ensures the reliability of the vertical connections, it still requires retaining some formwork on-site, which contradicts the principle of minimizing on-site work in modular construction.

[0004] Therefore, a new type of connection node is needed to achieve on-site formwork-free operation and solve the problem of vertical connection of shear walls between modules. Summary of the Invention

[0005] In view of this, the present invention provides a steel lock plate connection node, a shear wall structure, a shear wall and its installation method, which solves the problem of vertical connection of shear walls between modules, has sufficient shear resistance and energy dissipation function, and can realize a formwork-free construction process.

[0006] To address the aforementioned problems, in a first aspect, the present invention provides a steel lock plate connection node, comprising an embedded plate, a steel lock plate assembly, a first anchor bar group, and a second anchor bar group. The embedded plate has a first side and a second side disposed opposite to each other; the steel lock plate assembly is disposed on the first side of the embedded plate, and includes a first plate, a second plate, anchor bolt holes, and a fitting cavity.

[0010] In a second aspect, the present invention also provides a shear wall structure, including a first double-skin wall and a second double-skin wall. The second double-skin wall is arranged parallel to the first double-skin wall, and there is a building gap to be filled between the first double-skin wall and the second double-skin wall; a plurality of steel lock plate connection nodes are spaced apart in the building gap along the extension direction of the first double-skin wall, and the steel lock plate connection nodes are the steel lock plate connection nodes described in the first aspect.

The first shear wall is the shear wall structure described in the second aspect, and the first shear wall has a first steel locking plate connection node, the first steel locking plate connection node having a first fitting cavity; the second shear wall is the shear wall structure described in the second aspect, and the second shear wall has a second steel locking plate connection node, the second steel locking plate connection node having a second fitting cavity; the first shear wall and the second shear wall are configured to be nested and connected via the first steel locking plate connection node and the second steel locking plate connection node, and the first fitting cavity and the second fitting cavity at least partially overlap.

[0013] In some embodiments, the first steel lock plate connection node has a first anchor bolt hole, the second steel lock plate connection node has a second anchor bolt hole, and the shear wall structure includes an anchor bolt group, which includes a plurality of anchor bolts, each anchor bolt passing through the first anchor bolt hole and the second anchor bolt hole placed at the same height in sequence.

[0014] In a fourth aspect, the present invention provides a shear wall installation method applicable to the shear wall described in the third aspect, wherein a first shear wall has a first building gap, a second shear wall has a second building gap, and the shear wall installation method includes:

[0015] The first shear wall is placed vertically at the first preset position so that the first fitting cavity is opened in the first direction;

[0016] The second shear wall is moved vertically from top to bottom to the second preset position so that the second steel lock plate connection node is nested at the first steel lock plate connection node, the second fitting cavity is opened facing the second direction, the second direction is opposite to the first direction, and the first fitting cavity and the second fitting cavity at least partially overlap.

[0019] Before filling the first building gap, the second building gap, the first fitting cavity, and the second fitting cavity with concrete to form the shear wall, the following steps are also included:

[0020] The anchor rod is passed sequentially through the first anchor bolt hole and the second anchor bolt hole, which are placed at the same height.

[0057] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be particularly noted that the following embodiments are for illustrative purposes only and do not limit the scope of the invention. Similarly, the following embodiments are only some, not all, embodiments of the present invention, and all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0058] This invention provides a steel lock plate connection node based on a modular shear wall structure, which enables a formwork-free construction process, solves the problem of vertical connection between shear walls of modules, and has sufficient shear resistance and energy dissipation function.

[0059] Please see Figure 1 and Figure 2In a first aspect, this embodiment provides a steel lock plate connection node 1, including an embedded plate 11, a steel lock plate assembly, a first anchor bar group 14, and a second anchor bar group 15. The embedded plate 11 has a first side and a second side that are arranged opposite to each other. A steel lock plate assembly is disposed on the first side of the embedded plate 11. The steel lock plate assembly includes a first plate 12, a second plate 13, an anchor bolt hole 121, and a fitting cavity 122. The first plate 12 is vertically disposed on the embedded plate 11 and is disposed between the embedded plate 11 and the second plate 13 to form the fitting cavity 122. The first plate 12 is perpendicular to the second plate 13. Anchor bolt holes 121 are provided on the first plate 12. A first anchor bar group 14 is disposed on the second side of the embedded plate 11. The first anchor bar group 14 includes a plurality of first anchor bars, which are distributed at intervals along the vertical direction on the second side. A second anchor bar group 15 is disposed on the second side 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, which are distributed at intervals along the vertical direction on the second side. The first anchor bars and second anchor bars 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 of the steel locking plate assembly. They are arranged vertically and form a U-shaped structure with the embedded plate 11, i.e., a fitting cavity. The first plate 12 is provided with anchor bolt holes 121, which are used for the subsequent anchor rod 5 fixing process. Details are described later. It can be understood that the anchor bolt holes 121 can be located near the second plate 13 for easy splicing. The anchor bolt holes 121 facilitate the installation and fixing of the anchor rod 5, simplifying the construction process.

[0061] The first anchor bar group 14 and the second anchor bar group 15 are vertically spaced on the other side of the embedded plate. For ease of distinction, the two sides of the embedded plate 11 are referred to 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 multiple first anchor bars, which are vertically spaced on the second side, such as... Figure 1 and Figure 2 As shown, the second anchor bar group 15 includes multiple second anchor bars, which are distributed at intervals along the vertical direction on the second side, as shown in the figure. Figure 1 and Figure 2 As shown, it can be understood that the first anchor bar and the second anchor bar can be set at a height to correspond one-to-one, which can achieve a uniform distribution of anchoring force and improve the anchoring performance of the overall structure.

[0062] 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-skin wall as described later, the steel lock plate assembly can be directly fixed in the building gap of the shear wall structure 2 for easy further splicing and use.

[0063] In this embodiment, the first anchor bar group 14 is configured to be pre-embedded at a first preset depth within the first double-layer wall 21; the second anchor bar group 15 is configured to be pre-embedded at a second preset depth within the second double-layer wall 22. By setting 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 function, taking into account the transmission and distribution of force, reducing the risk of structural failure, and improving the overall structural safety. This facilitates the implementation of the formwork-free construction process for the shear wall during splicing, which aligns with the concept of minimal on-site work in modular construction.

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

[0065] In this embodiment, the eccentric arrangement of the first plate 12 ensures that the center of gravity of the entire steel lock plate connection node 1 remains at the geometric center, thereby improving the connection strength of the entire steel lock plate connection node 1. Simultaneously, the eccentric arrangement of the first plate 12 facilitates a larger overlap of the interlocking cavity during the subsequent splicing of two steel lock plate connection nodes 1, allowing for concrete pouring and ensuring the stress strength of the two steel lock plate connection nodes 1 after pouring. By setting the first plate 12 and the second plate 13 on the embedded plate 11, forming the interlocking cavity 122, this structural design provides better mechanical stability and load-bearing capacity when subjected to vertical and horizontal loads.

[0066] In this embodiment, the anchor bolt hole 121 is located close to the second plate 13. When the two steel lock plate connection nodes 1 are spliced, the space occupied by the anchor rod 5 connection can be reduced. The steel lock plate connection node 1 is placed in the building gap enclosed by the first double skin wall 21 and the second double skin wall 22 as much as possible, which improves the connection strength when the two shear wall structures 2 are spliced ​​and reduces the impact of the vertical connection node 61 on the overall connection structure at the connection point.

[0067] Please see 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; and 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, and the first length of the first anchor bar can be understood as the distance between the suspended end of the first anchor bar and the second side of the embedded plate 11. Similarly, the second length of the second anchor bar can be understood as the distance between the suspended end of the second anchor bar and the second side of the embedded plate 11. 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, avoiding the problem of the first plate 12 and the second plate 13 overturning on the embedded plate 11, thereby improving the anchoring force and making the connection more secure. During construction, 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] Please see Figures 3 to 6 In a second aspect, the present invention provides a shear wall structure 2, including a first double-skin wall 21 and a second double-skin wall 22. The second double-skin wall 22 is arranged parallel to the first double-skin wall 21, and there is a building gap to be filled between the first double-skin wall 21 and the second double-skin wall 22; a plurality of steel lock plate connection nodes 1 are arranged at intervals along the extension direction of the first double-skin wall 21 within the building gap, 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-skin wall 21 and the second double-skin wall 22 are two parallel walls in the shear wall structure 2, with a construction gap to be filled with concrete in between. Multiple steel lock plate connection nodes 1 are set at intervals along the extension direction of the first double-skin wall 21 in the construction gap to achieve effective connection between the double-skin walls, thereby improving the overall stability and load-bearing capacity of the shear wall.

[0071] Specifically, the first double-layer wall 21 and the second double-layer wall 22 can be constructed by laying steel bars and reinforcing cages, and then pouring concrete or other building materials, such as... Figures 3 to 6 The diagram illustrates the fabrication 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 during this process, there is a structural gap between the first double-skin wall 21 and the second double-skin wall 22; this gap is used for the subsequent fabrication of the shear wall.

[0072] In this embodiment, the embedded plate 11, the first anchor bar group 14, and the second anchor bar group 15 are all located at a certain distance inside the edges of the first double-layer wall 21 and the second double-layer wall 22. A portion of the structure of the first plate 12 protrudes outside the edges of the first double-layer wall 21 and the second double-layer wall 22 to facilitate the protrusion of the anchor bolt hole 121 to the outside. The second plate 13 is completely placed outside the edges of the first double-layer wall 21 and the second double-layer wall 22, thus forming a structure in which a partial fitting cavity protrudes outside, which facilitates the subsequent splicing of the two shear wall structures 2.

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

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

[0075] Please see Figures 7 to 9 In a third aspect, this 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 lock plate connection node 31, which has a first fitting 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 lock plate connection node 41, which has a second fitting cavity; the first shear wall 3 and the second shear wall 4 are configured to be nested and connected through the first steel lock plate connection node 31 and the second steel lock plate connection node 41, and the first fitting cavity and the second fitting cavity at least partially overlap.

[0076] In this embodiment, a shear wall, also known as a wind-resistant wall, earthquake-resistant wall, or structural wall, is a wall in a building or structure that primarily bears horizontal loads caused by wind loads or earthquakes, and is typically a reinforced concrete structure. This embodiment illustrates a specific structural form of how two shear walls can be combined to form a single shear wall. The fourth aspect describes a specific method for combining two shear walls into a single shear wall.

[0077] For ease of description, in this embodiment, the two shear walls are referred to as the first shear wall 3 and the second shear wall 4, respectively. Both the first shear wall 3 and the second shear wall 4 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 connection structure can be described in conjunction with… Figure 2 , Figures 7 to 9 For further understanding, the specific fitting method can be referred to the fourth aspect described later. For ease of description, the fitting cavity of the first steel lock plate connecting node 31 is referred to as the first fitting cavity, and the fitting cavity of the second steel lock plate connecting node 41 is referred to as the second fitting cavity. The first and second fitting cavities partially overlap through the fitting of the first steel lock plate connecting node 31 and the second steel lock plate connecting node 41. This partial overlap allows concrete to be poured simultaneously into the overlapping area of ​​the first and second fitting cavities during the pouring of the first shear wall 3 and the second shear wall 4, thus connecting the first shear wall 3 and the second shear wall 4. The shear wall 4 is integrated to form a whole. During this process, the fitting of the first steel lock plate connection node 31 and the second steel lock 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 lock plate connection node 31 and the second steel lock 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 the 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 nested connection of the first steel lock plate connecting node 31 and the second steel lock plate connecting node 41 ensures that the first and second fitting cavities at least partially overlap. This nested connection simplifies the construction process and reduces the amount of on-site welding or bolting. Simultaneously, the resulting vertical connecting node 61 has excellent load-bearing capacity, superior overall integrity, and improves overall neatness and aesthetics.

[0079] Please see Figure 7 and Figure 8 In this embodiment, the first steel lock plate connection node 31 has a first anchor bolt hole, the second steel lock plate connection node 41 has a second anchor bolt hole, and the shear wall structure 2 also includes an anchor bolt group, which includes multiple anchor bolts 5, each anchor bolt 5 passing through the first anchor bolt hole and the second anchor bolt hole placed at the same height in sequence.

[0080] For ease of description, the anchor bolt hole at the first steel lock plate connecting node 31 is referred to as the first anchor bolt hole, and the anchor bolt hole at the second steel lock plate connecting node 41 is referred to as the second anchor bolt hole. The first anchor bolt hole and the second anchor bolt hole are coaxial when the first and second fitting cavities are engaged. Figure 7 and Figure 8As shown, the anchor bolt 5 can pass through the first anchor bolt hole and the second anchor bolt hole, keeping the first steel lock plate connecting node 31 and the second steel lock plate connecting node 41 relatively fixed in the vertical direction.

[0081] In this embodiment, the anchor rod 5 is a component in an engineering structure, 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, depending on the actual needs. The anchor rod group includes multiple anchor rods 5, each anchor rod 5 corresponding to a first anchor bolt hole and a second anchor bolt hole at the same height. 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 anchor rod group further connects the two to form a whole, significantly enhancing the connection strength between the first shear wall 3 and the second shear wall 4, and improving the overall stability and load-bearing capacity of the structure.

[0082] Please see Figures 3 to 7 In a fourth aspect, the present invention provides a shear wall installation method 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 includes:

[0083] The first shear wall is placed vertically at the first preset position so that the first fitting cavity is opened in the first direction a;

[0084] The second shear wall is moved vertically from top to bottom to the second preset position so that the second steel lock plate connection node is nested at the first steel lock plate connection node, the second fitting cavity is opened facing the second direction b, the second direction b is opposite to the first direction a, and the first fitting cavity and the second fitting cavity at least partially overlap.

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

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

[0087] Specifically, the first shear wall 3 is placed vertically in a first preset position, which is a pre-reserved area for constructing the shear wall. This step requires ensuring that the first shear wall 3 is set vertically so that the first fitting cavity is opened in the first direction a.

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

[0089] Based on this, concrete is filled into the first building gap 32, the second building gap 42, the first fitting cavity, and the second fitting cavity. After the necessary curing process, a complete shear wall can be obtained.

[0090] The steps shown in this embodiment enable simple on-site installation of the first shear wall 3 and the second shear wall 4, minimizing the difficulty and steps of on-site assembly of shear walls, while ensuring the structural stiffness and stability of the first shear wall 3 and the second shear wall 4 after assembly.

[0091] Please see Figure 8 and Figure 9 In this embodiment, the first steel lock plate connection node has a first anchor bolt hole, the second steel lock plate connection node has a second anchor bolt hole, and the shear wall also includes an anchor bolt group, which includes multiple anchor bolts, each anchor bolt passing through the first anchor bolt hole and the second anchor bolt hole placed at the same height in sequence.

[0092] Before filling the first building gap, the second building gap, the first fitting cavity, and the second fitting cavity with concrete to form the shear wall, the following steps are also included:

[0093] The anchor rod is passed sequentially through the first anchor bolt hole and the second anchor bolt hole, which are placed at the same height.

[0094] In this embodiment, the through connection of the anchor rod 5 enhances the connection strength between the two first shear walls 3 and the second shear wall 4. The anchor rod 5 disperses and transfers the load, thereby improving the stability of the entire structure.

[0095] Please see Figure 10 , Figure 10 This is a modular building assembly diagram for this system, mainly including unit building modules 6, vertical connection nodes 61, and horizontal connection nodes. The modular building is mainly composed of stacked unit building modules 6, which are effectively connected through vertical connection nodes 61 and horizontal connection nodes to assemble the modular building.

[0096] The splicing process of vertical connection node 61 involves the aforementioned splicing process of the first shear wall 3 and the second shear wall 4. By using the aforementioned first shear wall 3, second shear wall 4, and corresponding installation methods, the current situation where formwork needs to be erected for vertical connection node 61 is solved, making on-site construction convenient and simple, improving module installation efficiency, and reducing the number of rebar binding steps; at the same time, it ensures the convenience and feasibility of unit module processing, the connection node is safe and reliable, reduces construction costs, reduces environmental pollution, and meets the requirements of sustainable development.

[0097] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art:

[0098] The first anchor bar group 14 is configured to be pre-embedded in the first double-layer wall 3 at a first preset depth; the second anchor bar group 15 is configured to be pre-embedded in the second double-layer wall 4 at a second preset depth. After vertical drop, the anchor rod 5 is inserted and fixed from the first anchor bolt hole and the second anchor bolt hole. By setting the first anchor bar group 14 and the second anchor bar group 15 on the embedded plate 11, stress can be dispersed, thereby improving the durability and service life of the structure. After fixing, the concrete poured in the first building gap 32, the second building gap 42, and the first and second fitting cavities can form an effective connection, which can solve the vertical connection problem of the shear wall between modules. It has sufficient shear resistance and energy dissipation function, takes into account the transmission and distribution of force, reduces the risk of structural failure through reasonable layout and structural design, improves the safety of the overall structure, realizes the formwork-free construction process, and fits the concept of less on-site work in modular buildings.
