[0002] Prefabricated modular units, as a core component of prefabricated buildings, play a crucial role. In the modern construction field, prefabricated modular units, due to their modular design and manufacturing process, greatly improve the efficiency and quality of construction projects. Factory prefabrication not only ensures consistent quality standards for each unit but also significantly reduces on-site workload and environmental impact. Furthermore, prefabricated modular units can be flexibly combined according to architectural design requirements to meet the needs of different functional spaces, and they excel in rapid assembly, providing an effective building solution for rapid urban development. Therefore, they have been widely used in residential, commercial, and public facility construction.

[0003] However, despite the conveniences offered by prefabricated enclosures, they also present several challenges in practical applications. Particularly during hoisting, installation precision issues can easily lead to splicing errors. Currently, the traditional method of using PE rods and sealant is commonly used for floor slab splicing. While this method addresses the sealing issue to some extent, it requires rework during secondary splicing after unpacking, increasing material, labor, and time costs. More seriously, when the gaps between floor slabs are large, traditional methods struggle to provide a reliable solution and lack versatility. Utility Model Content

Detailed Implementation

[0029] To better understand the above technical solutions, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present invention can be understood more clearly and thoroughly, and that the scope of the present invention can be fully conveyed to those skilled in the art.

[0030] Example 1:

[0031] Reference Figure 1 and Figure 2 This embodiment provides a detachable covering structure for floor slab joints, including a first component 1 and a second component 2. The first component 1 can be partially disposed within the joint 5 between a first floor slab 3 and a second floor slab 4. The top of the first component 1 near the first floor slab 3 has a first covering portion 14, which can cover the portion of the joint 5 near the first floor slab 3. The second component 2 is disposed on the first component 1 and located on the side of the first covering portion 14 near the second floor slab 4. The second component 2 has a second covering portion 21, which connects to the first covering portion 14 to cover the remaining portion of the joint 5.

[0032] More specifically, the side of the first covering part 14 away from the second covering part 21 overlaps and covers the upper surface of the edge of the first floor slab 3, and the side of the second covering part 21 away from the first covering part 14 overlaps and covers the upper surface of the edge of the second floor slab 4.

[0033] Thus, the first covering part 14 and the second covering part 21 cooperate to cover the joint 5 between the two floor slabs. The covering structure is dry-connected to the floor slabs on both sides, facilitating disassembly and maintenance. The covering structure can be prefabricated in the factory and quickly installed on site, improving construction speed. Compared with existing methods for treating joint gaps between floor slabs, this covering structure is suitable for covering larger gaps between floor slabs. In prefabricated buildings, it has a higher tolerance for hoisting errors and a certain weight-bearing capacity, increasing the stability of prefabricated buildings. Compared with existing technologies, this covering structure is easier to install and disassemble, improving construction efficiency; it is highly flexible in application and structurally stable.

[0034] Reference Figure 1 and Figure 2 This embodiment provides a detachable covering structure for floor slab joints. The first component 1 includes a first plate 11 and a first female groove 12 and a second female groove 13 disposed on the upper side of the first plate 11 and extending in parallel directions. The first plate 11, the first female groove 12, and the second female groove 13 are all located within the joint 5. The second component 2 also includes a first male buckle 22 and a second male buckle 23 disposed on the lower side of the second covering portion 21 and extending in parallel directions. The first female groove 12, the second female groove 13, the first male buckle 22, and the second male buckle 23 all extend along a first horizontal direction a, which is the length direction of the joint 5. When the second component 2 is installed onto the first component 1, the first male buckle 22 can rotate relative to the first female groove 12 to achieve a snap-fit ​​connection; the second male buckle 23 can rotate relative to the second female groove 13 to achieve a snap-fit ​​connection.

[0035] Reference Figures 1 to 6 This embodiment provides a detachable cover structure for floor slab joints. A first female groove 12 and a first male buckle 22 are disposed near the first floor slab 3, and a second female groove 13 and a second male buckle 23 are disposed near the second floor slab 4. Vertically, the first female groove 12 is lower than the second female groove 13, and the first male buckle 22 is lower than the second male buckle 23, facilitating installation. Specifically, the opening of the first male buckle 22 faces upward, and the opening of the second male buckle 23 faces horizontally towards the first male buckle 22. When the first component 1 and the second component 2 are installed, the first male buckle 22 rotates relative to the first female groove 12 to achieve a snap-fit ​​engagement between the first male buckle 22 and the first female groove 12. The second male buckle 23 rotates relative to the second female groove 13 to achieve a snap-fit ​​engagement between the two.

[0036] Thus, during the installation of the first component 1 and the second component 2, firstly, the second covering part 21 is tilted relative to the first plate 11 to engage the first female groove 12 and the first male buckle 22. Then, the second covering part 21 rotates downward around the first female groove 12 and the first male buckle 22 to engage the second female groove 13 and the second male buckle 23, facilitating installation. See also Figure 2When it is necessary to disassemble the first component 1 and the second component 2, push the second cover part 21 to the right, then lift the right edge of the second cover part 21 to separate the second female groove 13 and the second male buckle 23. Then, continue to lift the right edge of the second cover part 21, while moving the second cover part 21 to the right to separate the first female groove 12 and the first male buckle 22.

[0037] Reference Figure 5 The upper surface of the second cover part 21 is provided with an anti-slip strip 211 to improve the surface friction of the second cover part 21, so as to facilitate the displacement and rotation disassembly of the second cover part 21 when needed. Two or more anti-slip strips 211 can be provided at intervals, and the anti-slip strips 211 can specifically be serrated grooves opened on the upper surface of the second cover part 21.

[0038] It should also be noted that the first female groove 12 and the first male buckle 22, as well as the second female groove 13 and the second male buckle 23, all have sufficient space for relative horizontal movement to facilitate installation and disassembly. The use of male and female grooves for installation is convenient and quick. The two pairs of male and female grooves cooperate with each other to prevent the second cover part 21 from shifting relative to the first cover part 14 and the second floor slab 4. Furthermore, because the second female groove 13 and the first male buckle 22 have relatively long absolute lengths in the vertical direction, a reinforcing plate is provided on one side of the second female groove 13 to stably support it on the upper side of the first plate 11. A reinforcing plate is also provided on one side of the first male buckle 22 to stably support it on the lower side of the second cover part 21.

[0039] Reference Figures 1 to 6 This embodiment provides a detachable covering structure for floor slab joints. The first covering part 14 and the second covering part 21 are inclined and abut against each other on their adjacent sides, and the first covering part 14 is located above the second covering part 21 in the normal direction of the inclined surface. This allows the second covering part 21 to be rotatably installed above the first plate 11.

[0040] Reference Figures 1 to 6This embodiment provides a detachable covering structure for floor slab joints. The first component 1 further includes a first vertical plate 15 and a second vertical plate 16. The first plate body 11 is horizontally arranged, and the first vertical plate 15 is perpendicular to the first plate body 11 on the side of the first plate body 11 facing the first floor slab 3. The second vertical plate 16 is perpendicular to the first plate body 11 on the side of the first plate body 11 facing the second floor slab 4. The first vertical plate 15 and the second vertical plate 16 are opposite each other along a second horizontal direction b and respectively abut against the opposite side walls of the first floor slab 3 and the second floor slab 4. Wherein, the second horizontal direction b is perpendicular to the first horizontal direction a. The first covering part 14 is vertically arranged on the upper side of the first vertical plate 15. The second vertical plate 16 is located on the lower side of the first plate body 11, and the bottom of the first vertical plate 15 is lower than the first plate body 11. In this way, the bottom of the first vertical plate 15 and the second vertical plate 16 are opposite each other to form a symmetrical support function. The second vertical plate 16 is located on the lower side of the first plate body 11 so that there is sufficient installation space above the first plate body 11.

[0041] Further, see Figure 4 The first component 1 further includes a first anti-slip element 17 and a second anti-slip element 18. The first anti-slip element 17 is disposed on the side of the first vertical plate 15 facing away from the first plate body 11. The second anti-slip element 18 is disposed on the side of the second vertical plate 16 facing away from the first plate body 11. The first anti-slip element 17 and the second anti-slip element 18 are used to increase friction on both sides of the first component 1 along the second horizontal direction b, preventing the first component 1 from slipping. The first anti-slip element 17 and the second anti-slip element 18 can be saw-shaped rubber pads.

[0042] Reference Figure 4 It should be noted that, in order to enhance the supporting effect of the first vertical plate 15 and the second vertical plate 16 on the first plate body 11, at least one reinforcing plate 153 is provided on the first vertical plate 15 and the second vertical plate 16. The reinforcing plate 153, the first vertical plate 15 (or the second vertical plate 16) and the first plate body 11 form a supporting relationship with a triangular or quadrilateral cross section.

[0043] Reference Figures 1 to 6 This embodiment provides a detachable covering structure for the floor slab joint 5. The first component 1 further includes multiple mounting nails 19. A downwardly inclined fixing plate 152 is provided on the side of the first vertical plate 15 facing the first plate body 11, and the side of the fixing plate 152 away from the first vertical plate 15 is connected to the first plate body 11. At the same time, the fixing plate 152 is also supported on the reinforcing plate 153. The fixing plate 152 is used to install the mounting nails 19. The mounting nails 19 pass through the first vertical plate 15 perpendicularly to the fixing plate 152 and are fixed to the first floor slab 3 to fix the first component 1 to the first floor slab 3. The downwardly inclined fixing plate 152 helps to avoid interference from the first covering part 14 when screwing in the mounting nails 19, making construction more convenient. The multiple mounting nails 19 are spaced apart along the first horizontal direction a.

[0044] Example 2:

[0045] Reference Figure 1 This embodiment provides a prefabricated building, including a first floor slab 3 and a second floor slab 4, and a floor slab joint 5 formed between the first floor slab 3 and the second floor slab 4, and also includes the detachable covering structure for the floor slab joint 5 in Embodiment 1.

[0046] Here's a description of the assembly method for prefabricated buildings: First, horizontally install the first component 1 into the floor slab joint 5, ensuring the first covering part 14 fits snugly against the first floor slab 3. Then, install the mounting nails 19 onto the fixing plate 152 and the first floor slab 3 in sequence. Finally, tilt the second component 2, first fasten the first female groove 12 and the first male buckle 22, then rotate the second component 2 to fasten the second female groove 13 and the second male buckle 23, fitting the second covering part 21 against the first covering part 14 and the second floor slab 4, completing the installation. Disassembly is performed by reversing the above process, which will not be elaborated here.
