Specific embodiments

[0030] Typical embodiments embodying the features and advantages of the present utility model will be described in detail in the following description. It should be understood that the present utility model can have various changes in different embodiments, all of which do not depart from the scope of the present utility model, and the descriptions and illustrations therein are essentially for illustrative purposes and not for limiting the present utility model.

[0031] In the description of the present utility model, it should be understood that in the embodiments shown in the drawings, the indication of directions or positional relationships (such as up, down, left, right, front, and back, etc.) is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. When these elements are in the positions shown in the drawings, these descriptions are appropriate. If the descriptions of the positions of these elements change, then the indication of these directions also changes accordingly.

[0032] In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of the said features. In the description of the present utility model, the meaning of "a plurality" is two or more, unless otherwise specifically defined.

[0033] In actual use, the floor slabs between building modules are usually integrally cast in situ with reinforced concrete, or are welded with steel plates and bottom cross beams, so that the floor slabs between building modules can be stably connected between the building modules.

[0034] However, the floor slabs cast with reinforced concrete or the floor slabs welded with steel plates and bottom cross beams cannot be frequently disassembled, otherwise it is easy to cause unstable quality of the floor slabs and easily lead to safety problems. At the same time, disassembling the floor slabs cast with reinforced concrete or the floor slabs welded with steel plates and bottom cross beams will increase the workload of workers and have low disassembly efficiency, etc.

[0035] In addition, considering that there may be accumulated water at the bottom of the building module, it is necessary to frequently check and drain the accumulated water under the building module to ensure the safety of the building module. However, for the fixed bottom of the building module, it is not easy to detect the accumulated water at the bottom of the building module, nor is it easy to open the bottom of the building module to eliminate the hidden danger of accumulated water.

[0036] Although currently it is possible to cut openings in the bottom floor slab of the building module and use electronic probes to observe whether there is accumulated water at the bottom of the module, cutting openings in the bottom floor slab will reduce the bearing capacity of the floor slab, and there are also disadvantages such as a small observation range and difficulty in draining accumulated water. At the same time, in order to ensure the rigidity and integrity of the floor slab, the diameter of the openings cut in the floor slab should not be too large, and the number of openings cut should not be too many. And to observe the accumulated water and drainage conditions at the bottom of the floor slab from multiple directions and angles, it is inevitable to increase the number of openings in the floor slab. In addition, during the process of cutting openings, it is also necessary to ensure that the opening positions, sizes, and quantities will not have too much impact on the building floor surface, and corresponding reinforcement measures need to be taken to ensure the safety and stability of the overall building. Therefore, a precast floor slab is proposed to solve the above problems.

[0037] The solution is further illustrated by the following embodiments:

Among them, the bottom frame 11 is arranged at the bottom of the box body 10, and bolt holes are provided on the bottom frame 11 to install the precast floor slab 20 on the bottom frame 11 through bolts.

[0043] At the same time, the top plate 13 is connected to the bottom frame 11 through the support columns 14, so that the top plate 13 and the bottom frame 11 are spaced apart, and a living space is formed between the top plate 13 and the bottom frame 11.

[0044] Among them, the top plate 13 can be set as a metal top plate, and the support columns 14 can be set as metal support columns, so that the support columns 14 can support the top plate 13. The top plate 13 and the support columns 14 can be spliced or integrally cast, thus facilitating the manufacture of the top plate 13 and the support columns 14.

[0045] Referring to Figure 1 and Figure 4 , angle steels 12 are welded on the bottom frame 11, and bolt holes are provided on the angle steels 12 to facilitate connecting the precast floor slab 20 to the bottom frame 11 through bolts.

[0046] Among them, the angle steel 12 can be directly welded into the bottom frame 11, or welded to the cross beams and longitudinal beams of the bottom frame 11 to serve as a connecting piece for installing the precast floor slab 20.

[0047] Refer to Figure 3 , the box-type building module includes a plurality of precast floor slabs 20, and the plurality of precast floor slabs 20 are laid flat on the bottom frame 11 in the horizontal direction and spliced into the bottom plate of the box body 10.

[0049] Refer to Figure 4 and Figure 5 , the precast floor slab of this embodiment can be connected to the bottom frame 11 of the box-type building.

[0050] Specifically, the precast floor slab 20 can include a plate body 21 and a lifting ring 30. Among them, the plate body 21 can be set as a plate-shaped structure so that after the plate body 21 is laid, the plate body 21 can extend in the horizontal direction and form a flat bottom plate. It should be noted that the plate body 21 can be set as a rectangular plate cast with reinforced concrete or a steel plate body so that the plate body 21 can be connected to the bottom frame 11.

[0051] At the same time, a plurality of through holes 22 penetrating through the main body of the plate body 21 are formed in the plate body 21. The through holes 22 are used for passing through connecting pieces 40 so that the plate body 21 can be connected to the angle steel 12 of the bottom frame 11 through the connecting pieces 40. And the plurality of through holes 22 are distributed on the circumferential edge of the plate body 21 so that when the plate body 21 is connected to the bottom frame 11 through the connecting pieces 40, the plate body 21 can be stably connected to the bottom frame 11.

[0052] In this embodiment, the connecting piece 40 can be set as a bolt to fix the plate body 21 on the bottom frame 11.

[0053] It should be noted that after the plate body 21 is laid flat on the bottom frame 11, the four peripheral edges of the plate body 21 will abut against the angle steel 12 of the bottom frame 11, and the through holes 22 on the plate body 21 are aligned with the bolt holes on the angle steel 12. The connecting piece 40 is passed through the through holes 22 and the bolt holes, so as to fasten the plate body 21 to the angle steel 12 of the bottom frame 11 through the connecting piece 40.

[0054] Refer to Figure 5, a plurality of downwardly recessed accommodating portions 24 are also provided on the upper surface of the plate body 21. Among them, the accommodating portions 24 and the through holes 22 are arranged in one-to-one correspondence, so that after the connecting member 40 passes through the through hole 22, the end portion of the connecting member 40 can be accommodated in the accommodating portion 24, and the top surface of the connecting member 40 is lower than the upper surface of the plate body 21. That is, the accommodating portions 24 are provided on the plate body 21, and when the connecting member 40 is connected to the plate body 21 and the angle steel 12, it can prevent the top of the connecting member 40 from protruding from the plate body 21 and prevent the bolt head from protruding, thereby affecting the aesthetics and practicality of the precast floor slab 20.

[0055] Figure 6 is Figure 4 a schematic diagram of an embodiment of a precast floor slab. Figure 7 is Figure 4 a schematic diagram of another embodiment of a precast floor slab. Figure 8 is Figure 4 a schematic diagram of a cross-sectional view of a precast floor slab. Figure 9 is Figure 4 a schematic diagram of another cross-sectional view of a precast floor slab.

[0056] Refer to Figure 5 and Figure 6 , the lifting ring 30 can be provided on the plate body 21. Specifically, a downwardly recessed lifting portion 23 is provided on the upper surface of the plate body 21, and the lifting ring 30 is connected to the bottom of the lifting portion 23, so that the plate body 21 can be lifted by the lifting ring 30, facilitating the movement and transportation of the plate body 21, and also facilitating the lifting of the plate body 21 onto the bottom frame 11 to complete the installation of the plate body 21.

[0057] Among them, the lifting ring 30 can include a main body portion 31 and a fixing portion 32. The fixing portion 32 is embedded in the plate body 21, so that the lifting ring 30 can be stably connected in the plate body 21. At the same time, the main body portion 31 protrudes upward from the bottom surface of the lifting portion 23, so that an operator can connect a lifting device to the main body portion 31 in the lifting portion 23 to lift the plate body 21.

[0058] Refer to Figure 6 and Figure 7 , the fixing portion 32 and the main body portion 31 are arranged at an angle. Specifically, two fixing portions 32 can be provided, and the two fixing portions 32 can be located on the same side of the main body portion 31, as shown in Figure 6 . Of course, the two fixing portions 32 can also be respectively provided on opposite sides of the main body portion 31, as shown in Figure 7 . It should be noted that the main body portion 31 and the fixing portion 32 are arranged at an angle, which can enable the lifting ring 30 to be stably connected in the plate body 21 after being embedded in the plate body 21, so as to ensure that the lifting ring 30 does not fall off when lifting the plate body 21 through the lifting ring 30.

[0059] Refer to Figure 5 ,Figure 8 and Figure 9 The top of the lifting ring 30 is lower than the upper surface of the plate body 21, so as to ensure that after the precast floor slab 20 is paved on the bottom frame 11, the top of the precast floor slab 20 remains flat, thereby reducing the workload of floor leveling during subsequent decoration.

[0060] Meanwhile, both the lifting ring 30 and the lifting part 23 can be provided with a plurality of them, and the plurality of lifting parts 23 are arranged at intervals on the plate body 21, and the lifting ring 30 and the lifting part 23 are arranged in one-to-one correspondence, so as to facilitate the lifting mechanism to be able to connect a plurality of lifting rings 30 at the same time, and then lift the plate body 21 in a stable posture.

[0061] In addition, it should be noted that the precast floor slab 20 can be prefabricated first and then transported to the construction site for installation.

[0062] Of course, the precast floor slab 20 can also be directly cast on the construction site. Specifically, according to the design requirements of the engineering drawings, use wooden boards or plastic foam boards to assemble and make the formwork of the plate body 21, and ensure that the size of the formwork is accurate and the structure is firm. At the same time, use self-tapping screws to fix the wooden formwork on the bottom frame 11, and during the installation process, it is necessary to ensure the levelness, verticality and position accuracy of the formwork to ensure compliance with the design requirements. After the formwork is installed, it is necessary to use wooden formwork supports and fixings to ensure that the formwork can bear the weight of the concrete and the construction load. In addition, before tying the steel bars, first apply a release agent to the concrete pouring area, and install the bolt plastic pipe sleeves according to the bolt hole positions reserved on the angle steel 12 of the bottom frame 11 of the box-type building module. Subsequently, carry out the steel bar tying and concrete pouring work according to the construction specifications and the design requirements of the drawings. After the concrete of the plate body 21 has finally set, remove the formwork, take out the bolt plastic sleeves, and connect and fix the plate body 21 from top to bottom using bolts and bolt washers. In addition, when it is necessary to disassemble the plate body 21 from the bottom frame 11, first remove the connecting bolts on the plate body 21, and then use the pre-buried lifting ring 30 for lifting to complete the disassembly.

[0063] In summary, by setting the plate body 21 and the lifting ring 30, the precast floor slab 20 can enable the plate body 21 to be quickly lifted onto the bottom frame 11 through the lifting ring 30 and fastened to the bottom frame 11 through the connecting piece 40, thereby facilitating the installation or disassembly of the precast floor slab 20 and further reducing the damage to the bottom frame or the box-type building.
