Therefore, the structural system of modular buildings has gradually developed. The structural system of modular buildings is mainly divided into two categories: steel structure module system and concrete module system. At present, domestic modular buildings are mainly steel structure modules, with relatively mature technology, and are mostly used to build apartments, hotels, schools, dormitories, residences, offices and other types of buildings.
[0003] Although the modular system has many advantages in terms of rapid construction and cost savings, it has certain problems in flexibility and can only be applied to buildings with a single structure and cannot meet people's needs for diversified architectural space forms. Utility Model Content

[0044] See also Figure 6 (a) and (b) are schematic diagrams of the construction of the non-edge component wall component E in the prefabricated shear wall connection structure of the embodiment of the present disclosure. The non-edge component wall component E of the present embodiment is in a straight line shape as a whole, specifically a straight line wall limb, and the vertical steel bars E4 in the concrete wall of the non-edge component wall component E do not extend out of the wall, but a third grouting channel E5 is reserved at a position adjacent to the vertical steel bars in the concrete wall of the non-edge component wall component E, and an additional steel bar is respectively arranged in each of the third grouting channels E5 on site to realize indirect overlap of the vertical steel bars E4 in the upper and lower non-edge component wall components E, and the transverse steel bars in the concrete wall of the non-edge component wall component E are extended out of the two sides of the wall to form the second wall side steel bars E7.
[0045] Furthermore, the top and bottom extended bars of the edge component zone I in the corner wall component A, the edge wing wall component B, the window hole wall component C and the door hole wall component D, as well as the first wall side steel bar of the horizontal connection zone III and the second wall side steel bar E7 of the non-edge component wall component E are all in a closed U shape. More specifically, the top extended bars, the bottom extended bars, the first wall side steel bar and the second wall side steel bar are all closed structures at the end away from the wall edge. The length of the top extended bars, the bottom extended bars, the first wall side steel bar and the second wall side steel bar is not less than 1.2 times the seismic anchorage length. The spacing between the top extended bars and the bottom extended bars is consistent with the spacing between the vertical steel bars in the concrete wall of the edge component zone I of the component where the extended bars are located, and the spacing between the first wall side steel bar and the second wall side steel bar is consistent with the spacing between the transverse steel bars in the concrete wall of the component where the extended bars are located.
[0046] Furthermore, the upper surfaces of the edge component area I, non-edge component area II and horizontal connection area III in the corner wall component A, edge wing wall component B, window hole wall component C and door hole wall component D are flush; the lower surfaces of the wall of the non-edge component area II and horizontal connection area III in the corner wall component A, edge wing wall component B, window hole wall component C and door hole wall component D are flush and lower than the lower surface of the wall of the edge component area I in the same component, so as to form an operating space for on-site binding and connection of the top wall external reinforcement and the bottom wall external reinforcement at the bottom of the corner wall component A, edge wing wall component B, window hole wall component C and door hole wall component D, and serve as a post-casting area. After the top wall external reinforcement and the bottom wall external reinforcement are connected, it is necessary to arrange a template outside the operating space and pour grouting into the first grouting channel of the component where the external reinforcement is located. After the slurry is cured, the vertical connection between the edge component area I of the upper component and the edge component area I of the lower component can be achieved. Optionally, the lower surface of the wall in edge component area I of the corner wall component A, edge wing wall component B, window hole wall component C and door hole wall component D is 300 mm higher than the lower surface of the wall in non-edge component area II of the same component.
[0047] Furthermore, the length of the additional steel bars arranged in the corner wall component A, the edge wing wall component B, the window hole wall component C, the door hole wall component D and the non-edge component wall component E meets the requirements of the specification. The number of the second grouting holes in the non-edge component area II of the corner wall component A, the edge wing wall component B, the window hole wall component C and the door hole wall component D is the same as the number of vertical steel bars in the non-edge component area II; the third grouting holes in the non-edge component wall component E are arranged in a plum blossom shape, and the spacing between them is twice the spacing between the vertical steel bars in the concrete wall of the non-edge component wall component E, which can reduce the number of steel bar overlaps.
[0048] Furthermore, the grouting channels in each component are arranged along the vertical length of the wall. Among them, the first grouting channel in the edge component area I of the corner wall component A, the edge wing wall component B, the window hole wall component C and the door hole wall component D is located in the middle of the edge component area I and is used for node grouting. The second grouting channel in the non-edge component area II of the corner wall component A, the edge wing wall component B, the window hole wall component C and the door hole wall component D is arranged adjacent to a corresponding vertical steel bar in the non-edge component area II of each component, that is, the second grouting channel is not only used for grouting, but also for indirect overlap of the vertical steel bars in the non-edge component area II of the lower layer. The third grouting channel in the non-edge component wall component E is arranged in a plum blossom shape, and the third grouting channels of the upper and lower components are aligned. Optionally, each grouting channel adopts a circular hole with a diameter of 50mm to 80mm. The grouting material poured into each grouting channel can be high-performance concrete or high-strength grouting material.
[0049] See also Figure 7 (a), (b) Figure 7In the figure, the reference numeral "X" refers to any one of the corner wall component A, the edge wing wall component B, the window hole wall component C and the door hole wall component D. If X is A, Figure 7 The "X2" in the figure represents the bottom extension bar A2 in the corner wall component A, and the rest are the same; Figure 8 The meaning of the reference symbol "X" is the same as Figure 7 When assembling components on the same layer, first fix the corner wall component A, the edge wing wall component B, the window wall component C, and the door wall component D, then lift the non-edge component wall component E, and lower the non-edge component wall component E after aligning the wall, overlap the first wall side steel bars and the second wall side steel bars, and pour high-performance concrete or high-strength grouting material between the inner and outer concrete formworks of the horizontal connection area III to form a whole.
[0050] See also Figure 8 (a) to (d) are vertical connection structures of the edge component area and non-edge component area of the upper and lower components. When assembling the upper and lower components, first lift the upper component, insert additional steel bars into the second grouting holes reserved in the lower component, then align the second grouting holes reserved in the upper and lower components, lower the components to the lower component, and indirectly overlap the vertical steel bars in the non-edge component area of the lower component with the vertical steel bars in the upper component. Tie the top extension bars of the edge component area of the lower component to the bottom extension bars of the edge component area of the upper component. Support the formwork on site and pour the high-strength grouting material through the first grouting holes reserved in the wall.

[0052] See also Fig. 9, is a schematic diagram of the component division plane of the assembled shear wall connection structure provided according to this embodiment. The difference between this embodiment and embodiment 1 is that the combination form of the five components is different from that of embodiment 1. In this embodiment, four rooms ①, ②, ③, and ④ are formed by a combination method different from that of embodiment 1; wherein, room ① of this embodiment is a square room, and the component combination method is the same as that of room ① in embodiment 1, which will not be repeated here; room ③ of the rooms of this embodiment is T-shaped, and rooms ② and ④ are both L-shaped and symmetrically distributed on both sides of room ③, and room ② shares one wall with room ① (the wall is composed of 2 edge wing wall components B and 1 non-edge component wall component E), room ② and room ③ share three walls (the three walls are composed of 2 corner wall components A, 2 edge wing wall components B and 3 non-edge component wall components E), and room ④ and room ③ share three walls (the three walls are composed of 2 corner wall components A, 2 edge wing wall components B and 3 non-edge component wall components E). Room ② and room ④ each include 2 corner wall components A, 4 edge wing wall components B, 1 door hole wall component D and 7 non-edge component wall components E, and room ③ includes 4 corner wall components A, 4 edge wing wall components B, 1 window hole wall component C, 1 door hole wall component D and 10 non-edge component wall components E. The structure of each component in Example 2 is the same as that in Example 1, and will not be repeated here.
[0053] It can be understood that the embodiment of the present disclosure provides a prefabricated shear wall structure, which includes five components - corner wall component A, edge wing wall component B, window hole wall component C, door hole wall component D and non-edge component wall component E. Except for the non-edge component wall component E, the other components are divided into an edge component area, a non-edge component area and a horizontal connection area. In the horizontal direction, components A, B, C, D and component E are overlapped and grouted through the wall side steel bars in the horizontal connection area; in the vertical direction, the top extended bars of the edge component area of each component are overlapped with the bottom extended bars of the wall and grouted through the reserved first grouting hole to form a whole, and the second grouting holes of the upper and lower components in the non-edge component area are aligned, and additional steel bars are arranged therein to indirectly overlap the upper and lower vertical steel bars in the non-edge component area and grout through the reserved second grouting hole to form a whole. The non-edge component area is responsible for the vertical node connection and also serves as a support to fix the upper and lower components. Compared with the traditional prefabricated component connection, the prefabricated shear wall connection structure disclosed in the present invention avoids the node area with complex steel bars, reducing the workload of steel bar binding; the component connection node is simple in structure, easy to construct, and no steel bar tensioning is required, which greatly improves the construction efficiency; the non-edge component area does not require support during hoisting, and the inner and outer concrete formworks of the horizontal connection area can be used as templates, thereby reducing the use of support and templates. The shear wall structure disclosed in the present invention has a simple structure, convenient connection, and flexible assembly. It can meet different spatial layout requirements, and the workload of temporary support and wet operations is small.
