Description

Technical Field

[0001] The present invention relates to the field of advanced construction of prefabricated and concrete modular buildings, and in particular to a steel bar hook-connected modular wall and a construction method thereof. Background Art

[0002] Modular Integrated Construction (MiC) is a new type of prefabricated construction method that has been gradually developed and applied in recent years. It sits at the higher level of the modular building system and further emphasizes the intelligent construction of modular buildings, the degree of prefabrication of modular structural components, and the innovation of modular building structures. Unlike traditional prefabricated beams and columns, which are one-dimensional components, the modular units in modular buildings are three-dimensional spatial units. These units complete a large amount of structural, finishing, and plumbing and electrical work in the factory. This highly integrated approach can significantly reduce on-site work, improve on-site construction efficiency, and reduce construction waste. It is an efficient, green, and low-carbon construction method and the future development direction of the construction industry.

[0003] In multi-story modular buildings, prefabricated modules are typically combined with core tubes or shear walls to form a lateral load-bearing system. In most current projects, modules are not used as primary lateral load-bearing components. When shear walls are placed between modules, the modular walls serve only as casting formwork. After the modules are hoisted into place on site, shear wall reinforcement cages are hoisted into the cavities between adjacent modular walls. Formwork is then erected and concrete poured into the cavities. This method involves cumbersome on-site hoisting and formwork support, requiring significant manual labor. Furthermore, the volume of concrete poured is excessive, contradicting the original intention of modular construction, which was to reduce on-site labor. This has significantly increased the overall construction cost of most existing modular building projects. Furthermore, the wall thickness in this method is calculated as the sum of the cast-in-place area plus the thickness of the modular walls on either side. Under the same load conditions, the increased wall thickness reduces the actual usable interior area. These shortcomings have significantly limited the application and promotion of modular construction.

[0004] Therefore, designing modular walls as the main lateral load-bearing components is of great significance for improving the efficiency of material and component utilization, enhancing the overall load-bearing performance of the structure, reducing the project cost of modular combination buildings, and promoting the application and promotion of modular combination construction. In this case, the connection method between walls, especially the edge components, has a great impact on the load-bearing performance and construction difficulty of the modular wall. Some existing patents have proposed the use of special-shaped connectors for connection, such as half sleeves and buckles. However, the load-bearing mechanism of the above connection method is not clear, the connection effect is greatly affected by the component manufacturing process, and the integrity of the wall is difficult to guarantee. At the same time, there are also disadvantages such as complex connector manufacturing process and high production cost.

[0005] It should be noted that the information disclosed in the above background technology section is only used to understand the background of this application, and therefore may include information that does not constitute prior art known to ordinary technicians in this field. Summary of the Invention

[0006] The main purpose of the present invention is to overcome the defects existing in the above-mentioned background technology and provide a steel bar hook connection module wall and a construction method thereof.

[0007] To achieve the above object, the present invention adopts the following technical solutions:

[0008] In a first aspect of the present invention, a rebar hook connection modular wall comprises:

[0009] Concrete modular walls are butt-jointed and assembled, with horizontal and vertical reinforcement arranged inside the modular walls. Vertical through-grooves are provided in the edge member areas at the ends of the modular walls along the height of the wall, with the butt-jointed through-grooves forming a cavity.

[0010] A steel hook pre-buried in the edge member area, one end of the steel hook being buried in the modular wall and the other end extending out of the wall surface;

[0011] The corresponding steel bar hooks in the cavities of adjacent module walls are arranged centrally and symmetrically at the same level, with gaps formed between the bent sections of the corresponding steel bar hooks;

[0012] Inserting the vertical steel bars into the gaps between the bent sections of the steel bar hooks;

[0013] The pre-buried steel bar hooks and the post-inserted vertical steel bars form a connection structure after pouring concrete, so that the adjacent module walls can be stressed in a coordinated manner.

[0014] In some embodiments, the steel bar hook connection module wall of the present invention includes adjacent module walls that are butt-jointed and assembled. Horizontal steel bars and vertical steel bars are arranged in the module walls. A vertical through-groove is provided at the edge member on the opposite side of the module wall, and steel bar hooks are embedded in the through-groove area along the wall height. The steel bar hooks are arranged close to the horizontal steel bars of each layer, with inward bending sections at both ends, one end of which is embedded in the module wall and surrounds the vertical steel bars, and the other end extends out of the wall surface. The steel bar hooks of adjacent walls are arranged in a central rotationally symmetrical manner. There is a gap in the middle of the bending sections of the steel bar hooks of adjacent walls, and the rear-inserted vertical steel bars are arranged in the gap, and the size of the gap matches the diameter of the rear-inserted vertical steel bars. The length of the rear-inserted vertical steel bars is close to the floor height, and a portion of the upper end extends out of the top of the module wall. The area of the rear-inserted vertical steel bars is similar to the area of the vertical steel bars in the edge member area.

[0015] In a second aspect of the present invention, a method for constructing a modular wall with steel bar hooks includes the following steps:

[0016] (1) Hoist the adjacent concrete modular walls to the designed position, forming a vertical cavity between the two modular walls, so that the steel hooks corresponding to the two modular walls are arranged symmetrically at the same horizontal height, and leave gaps between the bent sections of the steel hooks;

[0017] (2) inserting the rear vertical steel bar into the gap between the bent sections of the steel bar hooks along the vertical direction;

[0018] (3) After installing the blocking devices on both sides of the module wall, pour concrete into the cavity to form an integrally connected steel hook module wall.

[0019] In some embodiments, the method for constructing modular walls connected by rebar hooks includes the following steps: During on-site installation, adjacent modules are first hoisted and lowered to a designated location, leaving a cavity between adjacent modular walls and a gap between the rebar hooks of adjacent walls. Lateral vertical rebar is then dropped from above the wall into the gap between the rebar hooks, with a portion of the upper end of the lateral vertical rebar extending beyond the top surface of the modular wall, serving as vertical connecting rebar between the upper and lower modules. Sealing devices are then installed on both sides of the modular wall, and finally, concrete is poured into the cavity to complete the connection between the adjacent walls and form the modular wall. Furthermore, the connection method for the module edge components can be arranged in the web area of the modular wall to improve the integrity of the modular wall.

[0020] The present invention has the following beneficial effects:

[0021] The present invention proposes a modular wall connected with steel hooks and a construction method. Through the collaborative connection design of pre-embedded steel hooks and post-inserted vertical steel bars, an efficient and reliable modular wall connected with steel hooks and a construction method are achieved. This solves the problems of complex adjacent wall connection processes, high component manufacturing costs, limited on-site lateral construction space, and insufficient wall integrity in existing modular buildings. In the modular wall connected with steel hooks of the present invention, a cavity is formed by vertical through-grooves in the edge component area of the modular wall. One end of the pre-embedded steel hook surrounds the vertical steel bar and is embedded in the wall, while the other end bends and extends out of the wall surface. A gap is formed between the bent sections of the symmetrically arranged steel hooks of adjacent modules, into which the post-inserted vertical steel bar is inserted, ultimately achieving an integral connection after concrete pouring. Compared to existing technologies, the technical solution of the present invention eliminates the need for special-shaped steel plates or complex spiral stirrup connectors, simplifies the form of connecting components, and significantly reduces material costs and processing difficulty. Through the synergistic effect of steel hooks and post-inserted vertical steel bars, it not only provides effective constraints for the edge component concrete to improve the wall's lateral resistance, but also achieves continuous anchoring of the upper and lower modules through the vertical extension of the post-inserted steel bars, without the need for additional connecting steel bars. At the same time, this connection method does not require lateral construction operations, and all processes are completed through vertical hoisting from the top, significantly improving construction efficiency and reducing on-site work. By optimizing the connection structure, the amount of post-poured concrete is reduced, the wall thickness is effectively controlled, and the indoor usable area is increased. This balances structural performance, construction convenience, and economic benefits, providing an innovative solution for the efficient construction and promotion of modular buildings.

[0022] Compared with the prior art, the present invention has the following significant advantages:

[0023] The rebar hook-connected modular wall disclosed in this invention effectively connects adjacent walls horizontally through pre-embedded rebar hooks and vertically inserted rebar. When the wall is under compression, the tension provided by the rebar hooks combined with the inserted vertical rebar restrains the concrete in the edge member area, enhancing the wall's load-bearing performance.

[0024] 2. The steel bar hook connection module wall disclosed in the present invention avoids the use of special-shaped spiral stirrups or steel plate connectors. The steel bar material is easy to obtain, the cost is low, the factory production process is simple, and the material precision is easy to control.

[0025] 3. The steel bar hook connection module wall disclosed in the present invention can give full play to the efficient construction advantage of modular combination buildings by hoisting vertical steel bars from the top, without the need for on-site lateral working surfaces.

[0026] 4. The steel bar hooks disclosed in the present invention connect the modular walls, so that adjacent modular walls form an overall coordinated force, thereby improving material utilization efficiency.

[0027] 5. The steel bar hook connection module wall disclosed in the present invention reduces the increase in wall thickness originally caused by a large amount of post-poured concrete, increases the indoor usable area of the module, and improves the economic benefits of construction.

[0028] 6. The rebar hooks used in the modular wall connection disclosed in this invention can also serve to connect the upper and lower walls by using the post-insertion vertical rebar structure. The rebar hooks can also restrain the vertical rebar, enhancing its anchoring performance.

[0029] Other beneficial effects of the embodiments of the present invention will be further described below. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] The present invention aims to solve the problems of complex connection methods for adjacent walls, high component manufacturing costs, limited on-site lateral construction space, and difficulty in ensuring wall integrity in existing modular construction. A modular wall connected by steel hooks and a construction method thereof are proposed.

[0045] See Figures 1 to 10 , an embodiment of the present invention provides a steel bar hook connection module wall, comprising: concrete module walls 1 that are butt-jointed and assembled with each other, each module wall 1 may include one or more concrete modules 7, horizontal steel bars 3 and vertical steel bars 4 are arranged in the module wall 1, and the edge component area at the end of the module wall 1 is provided with a vertical through groove 2 along the wall height direction, and the butted through grooves 2 form a cavity 8; steel bar hooks 5 pre-buried in the edge component area, one end of the steel bar hook 5 is buried in the module wall 1, and the other end extends out of the wall surface; the corresponding steel bar hooks 5 in the cavity 8 of adjacent module walls 1 are arranged centrally and symmetrically at the same horizontal height, and gaps are formed between the bent sections of the corresponding steel bar hooks 5; and the later-inserted vertical steel bars 6 are inserted into the gaps between the bent sections of the steel bar hooks 5; wherein, the pre-buried steel bar hooks 5 and the later-inserted vertical steel bars 6 form a connection structure after pouring concrete, so that the adjacent module walls 1 are subjected to force in a coordinated manner.

[0046] In the embodiment of the present invention, the rebar hooks connect modular walls. A through slot 2 is defined along the height of the wall in the edge member area of the modular wall 1. Pre-embedded rebar hooks 5 and post-inserted vertical rebar 6 are arranged in this edge member area. The rebar hooks 5 are arranged along the height of the wall, with both ends bent inward. One end is embedded in the wall and surrounds the vertical rebar 4, while the other end extends out of the wall surface. During on-site installation, adjacent modules are first lowered to the designated position, leaving a gap between the rebar hooks 5 extending from the modules on both sides. The post-inserted vertical rebar 6 is then inserted vertically into the gap between the rebar hooks 5. A sealing device is then installed on both sides of the modular wall 1, and finally, concrete is poured to complete the connection of the modular wall 1.

[0047] In some embodiments, the thickness of the edge member region is less than the thickness of the wall web region, and the vertical through groove 2 runs through the entire height of the modular wall 1 .

[0048] See Figure 5 In some embodiments, one end of the steel bar hook 5 embedded in the modular wall 1 surrounds the vertical steel bar 4 .

[0049] In some embodiments, the steel bar hooks 5 are arranged along the height of the wall, and their positions are close to the horizontal steel bars 3 in the modular wall 1.

[0050] See Figures 1 to 6 In some embodiments, both ends of the steel bar hook 5 are bent inward, and the bent section extending out of the wall surface exceeds the plane of the wall web.

[0051] In some embodiments, the length of the post-inserted vertical reinforcement 6 is close to the building floor height, and the area is close to the area of the vertical reinforcement 4 in the edge member area.

[0052] See Figures 6 to 9 In some embodiments, the upper end portion of the post-inserted vertical reinforcement 6 extends out of the top surface of the modular wall 1 to connect the upper and lower modular walls.

[0053] See Figure 10 In some embodiments, the edge member connection extends to the wall web, with the rebar hooks 5 and post-insertion vertical rebars 6 arranged along the entire length of the wall. The edge member connection further extends to the web of the modular wall 1 to enhance integrity.

[0054] See Figure 10 In some embodiments, a groove 11 is provided in the wall web region, and the protruding end of the steel bar hook 5 in the wall web region protrudes from the groove 11 .

[0055] The embodiment of the present invention further provides a method for constructing the modular wall with steel bar hooks, comprising the following steps:

[0056] (1) Hoist the adjacent concrete modular walls 1 to the designed position, forming a vertical cavity 8 between the two modular walls 1, so that the steel hooks 5 corresponding to the two modular walls 1 are arranged symmetrically at the same horizontal height, and leave gaps between the bent sections of the steel hooks 5;

[0057] (2) inserting the rear vertical steel bar 6 into the gap between the bent sections of the steel bar hook 5 along the vertical direction;

[0058] (3) After installing the blocking devices 9 on both sides of the module wall 1, concrete is poured into the cavity 8 to form the module wall 1 with the steel bar hooks 5 connected as a whole.

[0059] In some embodiments, the post-insertion vertical reinforcement 6 in step (2) is installed by vertically dropping from the top of the modular wall 1 , with the upper end portion extending out of the top surface of the modular wall 1 .

[0060] In some embodiments, the rebar hook 5 connection method at the edge member of the modular wall 1 is applied to the web area of the modular wall 1 to further improve the integrity of the modular wall.

[0061] Example 1

[0062] like Figure 1-Figure 5 The steel bar hook connection module wall shown includes module walls 1 that are butt-jointed and assembled with each other. A groove 2 that runs through the height of the wall is provided at the edge member on the outside of the module wall 1. Horizontal steel bars 3 and vertical steel bars 4 are arranged inside the module wall 1. Steel bar hooks 5 are arranged along the height of the wall at the edge member, and the steel bar hooks are located close to the horizontal steel bars. There are bent sections at both ends of the steel bar hooks. One end of the steel bar hook is pre-embedded in the module wall 1 and surrounds the vertical steel bar 4, while the other end extends out of the wall surface. The steel bar hooks of adjacent walls are distributed in a central rotationally symmetrical manner, with a gap left in the middle of the bent section of the steel bar hooks. The later inserted vertical steel bar 6 is located between the bent sections of the steel bar hooks, forming a composite connection of the steel bar hook on one side - the later inserted vertical steel bar - the steel bar hook on the other side.

[0063] like Figure 6-Figure 9 The figure shows the on-site construction process for connecting modular walls with rebar hooks. After adjacent concrete modules 7 are lowered vertically into place on site, a cavity 8 is left between the adjacent modular walls 1. Lateral vertical rebar 6 is then lowered vertically from the top of the wall, passing through the gaps between the rebar hooks to form a rebar hook connection. The upper ends of the lateral vertical rebar 6 extend partially beyond the top surface of the wall. Sealing devices 9 are then installed on both sides of the modular wall. Finally, concrete 10 is poured into the cavities in the edge area of the modular wall, completing the modular wall component.

[0064] Example 2

[0065] like Figure 10As shown, this embodiment arranges the connections within the edge member area along the entire length of the modular wall 1. Grooves 11 are provided in the wall web, allowing the rebar hooks 5 to extend beyond the wall surface. The construction method is the same as in Example 1. The spacing between the grooves and the number of rebar hooks within the grooves can be determined according to design requirements. This approach further enhances the overall connection strength between the modular walls 1 and is suitable for use at critical load-bearing modules and joints in modular building structures, as well as when the modular walls are long.

[0066] In summary, to address the complex connection methods for adjacent walls, the difficulty in component fabrication, limited on-site construction space, and the difficulty in ensuring wall integrity in conventional modular construction, the present invention provides a modular wall with steel hooks and a construction method thereof. These methods effectively provide horizontal tension between adjacent walls, enhance the integrity of the modular walls, and enable effective coordination of adjacent walls. Furthermore, in the production and construction of concrete modular buildings, these methods reduce manufacturing and on-site construction difficulties, ensure installation precision, and improve construction efficiency.

[0069] 2. The steel bar hook connection module wall disclosed in the present invention avoids the use of special-shaped spiral stirrups or steel plate connectors. The steel bar material is easy to obtain, the cost is low, the factory production process is simple, and the material precision is easy to control.
