[0032] This section will combine Figures 1 to 9Embodiments of the present application are described in detail, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.

The features defined as "first" and "second" are used to distinguish the feature names, rather than having special meanings. In addition, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present application, unless otherwise specified, "multiple" means two or more.

[0034] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0035] like Figure 1 As shown, the embodiment of the present application provides a modular building prefabricated parapet installation structure, which includes a modular box 101 and a parapet structure 102. The modular box 101, as a unit constituting a modular building, includes a modular housing, a modular beam and a modular plate. The modular housing and the modular beam form a frame structure of the modular box 101. The modular plates are arranged on each surface of the frame structure. The modular box 101 is integrally cast by concrete. According to the position of the modular plate, the modular plate is divided into a top plate, a bottom plate and a side plate.

[0036] Furthermore, the modular box 101 is provided with a support structure, and the parapet structure 102 is connected to the modular box 101 through the support structure, and forms a top opening area above the top plate of the modular box 101. The parapet structure 102 is arranged on the top of the support structure, and the support structure can not only bear the weight of the parapet structure 102 but also play a certain positioning role for the parapet structure 102, so as to prevent the parapet structure 102 from falling off the modular box 101.

[0037] At the same time, a gap is formed at the connection position between the parapet structure 102 and the supporting structure, and water outside the modular box 101 may flow along this contact gap to the top of the modular box 101, causing the problem of roof leakage. Therefore, the height of the contact gap between the parapet structure 102 and the supporting structure is less than the height of the top plate of the modular box 101, forming a height difference. It is difficult for water outside the modular box 101 to overcome its own gravity and reach the top plate of the modular box 101 with a larger height along the gap, thereby avoiding the problem of roof leakage.

[0038] like Figure 2 As shown, in the first embodiment, the parapet structure 102 includes a connecting portion 201 and an extending portion 202, and the connecting portion 201 and the extending portion 202 are at an angle. Specifically, the connecting portion 201 and the extending portion 202 are perpendicular to each other, so that the cross-sectional shape of the parapet structure 102 is substantially formed into an "L-shape".

[0039] Further, when the connecting portion 201 and the extending portion 202 are perpendicular to each other, the connecting portion 201 is approximately horizontal and the extending portion 202 is approximately vertical. The first end of the connecting portion 201 is connected to the first end of the extending portion 202, the second end of the connecting portion 201 is connected to the modular box 101, and the bottom of the connecting portion 201 is connected to the supporting structure. The second end of the extending portion 202 extends toward the top of the modular box 101, so that the height of the extending portion 202 is greater than the height of the top plate of the modular box 101. Specifically, the length of the parapet structure 102 is set to 280 mm and the width is set to 130 mm.

[0040] like Figure 2 and Figure 3 As shown, in some examples, the support structure includes a cantilever plate 203, which is integrally cast with the modular box 101, and is located on the side plate of the modular box 101 and extends away from the modular box 101. At the same time, the top of the cantilever plate 203 is approximately horizontal, and the connecting portion 201 is arranged on the top of the cantilever plate 203. Since the bottom of the connecting portion 201 and the top of the cantilever plate 203 are both formed into a plane, it is convenient for the connecting portion 201 to fit the cantilever plate 203, thereby playing a certain positioning role. It can be understood that the cantilever plate 203 bears the weight of the parapet structure 102 in a manner of supporting the parapet structure 102.

[0041] Specifically, the length of the cantilever plate 203 is set to 300 mm, and the width is set to 150 mm, and the length and width of the cantilever plate 203 can be adjusted according to design requirements.

[0042] It is worth noting that the traditional prefabricated parapet wall needs special work such as formwork during on-site construction, which will greatly increase the construction cost when the construction surface is insufficient or the floor is high. The cantilever plate 203 used in the first embodiment can effectively optimize the construction process, avoid formwork work, save costs, and is easy to operate.

[0043] In some examples, the gap between the parapet structure 102 and the cantilever plate 203 is at the top of the cantilever plate 203. To ensure that the height of the gap between the parapet structure 102 and the cantilever plate 203 is less than the height of the top plate of the modular box 101, the top height of the cantilever plate 203 is less than the height of the top plate of the modular box 101, so as to prevent the water outside the modular box 101 from flowing along the gap to the top of the modular box 101. Specifically, a distance of 150 mm is reserved from the top of the cantilever plate 203 to the top of the modular box 101.

[0044] like Figure 1 As shown, in some examples, in order to ensure a stable connection between the parapet structure 102 and the modular box 101, the modular box 101 is provided with a connection structure 401, and the connection structure 401 extends from the inside of the modular box 101 to the outside of the modular box 101. At the same time, the parapet structure 102 is provided with a first cavity 403, and the connection structure 401 is inserted into the first cavity 403. Specifically, the first cavity 403 is provided with a docking port, and the connection structure 401 is inserted into the first cavity 403 along the docking port.

[0045] Further, several groups of connection structures 401 are provided, and several groups of first cavities 403 and docking ports are also provided, and each group of connection structures 401 is respectively inserted into each first cavity 403. Among them, the connection structure 401 is located at the top of the cantilever plate 203, and the extension direction is approximately the same as the extension direction of the cantilever plate 203. The second end of the connection part 201 of the parapet structure 102 is provided with a docking port to ensure smooth insertion of the connection structure 401. Specifically, the connection structure 401 includes steel bars reserved outside the modular box 101.

[0046] In some examples, the parapet structure 102 is provided with a grouting port 402, the grouting port 402 is connected to the first cavity 403, and the slurry is poured into the first cavity 403 along the grouting port 402, so that the steel bars are consolidated in the parapet structure 102, and the connection strength between the parapet structure 102 and the modular box 101 is ensured. Furthermore, the grouting port 402 is located at the top of the connection portion 201 of the parapet structure 102, which is convenient for pouring the slurry.

[0047] It is understandable that the connection structure 401 may extend from the module column of the modular box 101 to the outside, or may extend from the module beam of the modular box 101 to the outside. When the connection structure 401 is on the module column, the first cavity 403 is connected to the module column; when the connection structure 401 is on the module beam, the first cavity 403 is connected to the module beam.

[0048] like Figure 4 , Figure 6 , Figure 7 and Figure 8 As shown, in the second embodiment, the parapet structure 102 has no bends. After the parapet structure 102 is installed in the modular box 101, the outer facade of the wall is guaranteed to be flat without affecting the overall beauty of the building.

[0049] The support structure includes a concave structure 302, which is located at the top edge of the modular box 101. It can be understood that the concave structure 302 is located on the module column and the module beam. The concave structure 302 extends a certain distance to the bottom of the modular box 101, thereby forming a step structure at the top edge of the modular box 101, and the step structure has a step surface with a height difference.

[0050] Furthermore, a convex structure 301 is provided at the bottom of the parapet structure 102, and the convex structure 301 also extends a certain distance toward the bottom of the modular box 101, thereby forming a step structure at the bottom of the parapet structure 102, and the step structure has a step surface with a height difference. At the same time, the concave structure 302 and the convex structure 301 extend downward by approximately the same distance, so that the convex structure 301 can be embedded in the concave structure 302, forming a chimeric positioning between the parapet structure 102 and the modular box 101.

[0051] In addition, an inclined connecting portion is provided between the step surfaces formed by the concave structure 302, and an inclined connecting portion is also provided between the step surfaces formed by the convex structure 301. When the convex structure 301 and the concave structure 302 are interlocked, the two connecting portions also fit each other.

[0052] In some examples, due to the presence of the mutually engaged convex structure 301 and the concave structure 302, the contact gap between the parapet structure 102 and the modular box 101 is formed into a step-shaped structure, the smaller portion of the step-shaped structure is connected to the outside of the modular building, and the larger portion is connected to the area enclosed by the parapet structure 102 at the top of the modular box 101. To prevent water outside the modular box 101 from flowing to the top of the modular box 101, the height of the smaller portion of the step-shaped structure is less than the height of the top plate of the modular box 101.

[0053] like Figure 5 and Fig. 9 As shown, in some examples, the contact gap between the parapet structure 102 and the modular box 101 extends to the edge of the area enclosed by the parapet structure 102. At the same time, a water guide structure 303 is provided on the top of the parapet structure 102. The water guide structure 303 is provided along the inner edge of the parapet structure 102 and extends inward by a certain distance, so that the edge of the area enclosed by the parapet structure 102 and the edge of the water guide structure 303 form a horizontal misalignment. When water reaches the top of the parapet structure 102, the water will flow down along the edge of the water guide structure 303, avoiding water from directly accumulating at the edge of the area enclosed by the parapet structure 102, that is, avoiding water from penetrating into the wall along the contact gap. Among them, the top of the parapet structure 102 has a slope, which is conducive to water flowing along the slope to the edge of the water guide structure 303.

[0054] like Figure 4 and Figure 5 As shown, in some examples, a connection structure 401 is provided on the modular box 101, and the connection structure 401 extends from the inside to the outside of the modular box 101. At the same time, the parapet structure 102 is provided with a second cavity 404, and the connection structure 401 is inserted into the second cavity 404. Specifically, the second cavity 404 is provided with an insertion opening, and the connection structure 401 is inserted into the second cavity 404 along the insertion opening.

[0055] Furthermore, a plurality of connection structures 401 are provided, wherein the connection structure 401 is located at the top of the module beam of the modular box 101 and extends toward the top, and an insertion port is provided at the bottom of the parapet to ensure smooth insertion of the connection structure 401 .

[0056] Specifically, the connection structure 401 includes steel bars reserved outside the modular box 101, and the number of the steel bars is calculated and configured according to the actual structure.

[0057] In some examples, the parapet structure 102 is provided with a grouting port 402, the grouting port 402 is connected to the second cavity 404, and the slurry is poured into the second cavity 404 along the grouting port 402, so that the steel bars are consolidated in the parapet structure 102, and the connection strength between the parapet structure 102 and the modular box 101 is ensured. Furthermore, the grouting port 402 is located on the inner side wall of the parapet structure 102, which is convenient for pouring the slurry.

[0058] At the same time, the provision of the second cavity 404 can reduce the weight of the parapet structure 102, play a certain lightweight role, and reduce transportation pressure.

[0059] In some examples, in order to further improve the connection strength between the parapet structure 102 and the supporting structure, the contact gap between the parapet structure 102 and the supporting structure is filled with an adhesive structure 405. Specifically, the adhesive structure 405 is made of polymer waterproof mortar.

[0060] In the description of this specification, if the reference terms "one embodiment", "some examples", "some embodiments", "illustrative embodiment", "example", "specific example", or "some examples" appear, it means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.

[0061] The above describes the implementation methods of the present application in detail in conjunction with the accompanying drawings, but the present application is not limited to the above implementation methods. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present application.
