Description

Technical Field

[0001] The present invention relates to the technical field of prefabricated bathrooms, and particularly to a prefabricated bathroom overhead floor structure. Background Art

[0002] With the continuous development of society and the rapid increase in population, due to the characteristics of prefabricated product components such as standardized design, factory production, prefabricated construction, energy conservation, environmental protection, shortened construction period, and improved quality, prefabricated construction has gradually become the mainstream of construction. At present, prefabricated bathrooms have been fully applied in prefabricated buildings.

[0003] At present, a same-floor drainage system is adopted for the bathroom floor. The same-floor drainage system means that the bathroom floor is designed as an overhead floor, so that the drain pipes in the bathroom are installed in the overhead space under the floor, and the drain pipes are connected to the building drainage riser on this floor. In this regard, when installing the bathroom floor, it is supported and elevated by leveling parts. However, the existing leveling parts are all rigid support parts. When the bathroom floor is stressed, the acting force will be directly transmitted to the leveling parts, easily causing fatigue damage to the leveling parts. In addition, when the user steps on the bathroom floor, the stepped area will be depressed and deformed to a certain extent under stress. When the user does not step on this area, the depressed and deformed area will return to its original shape due to elasticity. The vibration generated during the process of the floor being stressed, depressed, and elastically restored to its original shape will also act on the leveling parts, easily damaging the fixing bolts between the top of the leveling parts and the floor and the leveling parts, seriously affecting the normal working life of the floor. Summary of the Invention

[0004] The present invention provides a prefabricated bathroom overhead floor structure, in which the bathroom floor is supported and elevated by damping support parts to extend the service life of the support parts, so as to solve the above technical problems.

[0005] The technical solution adopted by the present invention to solve the above problems is: to provide a prefabricated bathroom overhead floor structure, including a floor, overhead keels, dampers, and drainage pipes. The overhead keels are fixedly installed on the floor of the bathroom. The dampers are fixedly installed above the overhead keels and support the bottom of the floor. A water flow port is opened on the floor, and the drainage pipe is communicated with the water flow port, and the drainage pipe is installed between the floor and the original floor.

[0006] Further, there are multiple overhead keels; the overhead keel includes a bottom keel plate, a vertical keel plate, and a top keel plate. The lower end of the vertical keel plate is integrally connected to the bottom keel plate, the upper end of the vertical keel plate is integrally connected to the top keel plate, and the top keel plate and the bottom keel plate are parallel to each other.

[0007] Further, structural reinforcing ribs are connected and arranged between the bottom surface of the top keel plate and the side wall of the vertical keel plate, and between the side wall of the vertical keel plate and the upper surface of the bottom keel plate.

[0008] Furthermore, a structural cavity is opened on the vertical keel plate.

[0009] Furthermore, the drainage pipe passes through the structural cavity, and the height of the structural cavity is greater than the diameter of the drainage pipe.

[0010] Furthermore, a plurality of dampers are provided; the dampers are fixedly mounted on the vertical keel plates, a mounting through hole is provided on the top keel plate, and the upper end of the damper passes through the mounting through hole to support the floor.

[0011] Furthermore, a plurality of threaded fixing holes are provided on the vertical keel plate, and the damper is fixedly mounted on the side wall of the vertical keel plate by means of bolt fixing connection.

[0012] Furthermore, the structural reinforcement ribs and the damper are located on the same side of the vertical keel plate.

[0013] Furthermore, the damper is a hydraulic damper, and a support sheet is provided at the rod end of the piston rod of the damper.

[0014] Furthermore, an adhesive sheet is provided on the upper surface of the support sheet.

[0015] Beneficial effects of the present invention:

[0016] 1. Use dampers as support parts to replace traditional rigid support leveling parts to solve the problem of short overall service life of the overhead ground structure due to the use of rigid support parts.

[0017] 2. When a rigid leveling member is used to support the floor, the technician must adjust the rigid leveling member to a height where the top just touches the floor; however, when the present application uses a damper as a support, since the damper itself will change in length (elongate or shorten) when subjected to force, the technician does not have to adjust the initial height of the damper to a state where it must just touch the floor like a rigid leveling member, thereby reducing the difficulty of the floor installation leveling operation and improving installation efficiency.

[0018] 3. Since the damper is used as support in this application, when the floor bears weight, the length of the damper will change when releasing the force, which will cause the overall height of the floor to change. In order to prevent the drainage pipe from being affected by the rise and fall of the floor, a structural cavity is opened on the overhead keel, and the height of the structural cavity is greater than the drainage pipe; when the floor bears weight and the height changes, the drainage pipe will rise and fall accordingly, but the drainage pipe will not interfere with the overhead keel when moving, affecting drainage.

Detailed implementation manners

[0025] The orientation terms such as up, down, left, right, front, back, front side, back side, top, bottom, etc. mentioned or possibly mentioned in this specification are defined with respect to the structures shown in the respective drawings. The terms "inner" and "outer" respectively refer to the directions towards or away from the geometric center of a specific component. They are relative concepts and thus may change accordingly depending on their different positions and different usage states. Therefore, these or other orientation terms should not be construed as restrictive terms.

[0026] Please refer to Figures 1 to 4, An assembled bathroom elevated floor structure according to a specific embodiment of the present invention includes a floor 1, elevated keels 2, dampers 3, and drainage pipes 4; the elevated keels 2 are directly and fixedly arranged on the original floor of the bathroom. There are multiple elevated keels 2, and the multiple elevated keels 2 are evenly distributed on the original floor of the bathroom; multiple dampers 3 are fixedly installed on each elevated keel 2. Each damper 3 is in a vertical installation posture. The main structure of the damper 3 is fixedly installed on the elevated keel 2, and the upper end of the piston rod of the damper 3 is fixedly connected to the bottom of the floor 1; when the floor 1 is laid in the bathroom, due to the arrangement of the elevated keels 2 and the dampers 3 between the floor 1 and the original floor of the bathroom, an elevated space is formed. The drainage pipe 4 is located in this elevated space. A water outlet 5 is opened on the floor 1. The water inlet end of the drainage pipe 4 is fixedly connected to the floor 1 at the water outlet 5, and the water outlet end of the drainage pipe 4 is communicated with the same-floor drainage system.

[0027] When the assembled bathroom elevated floor structure of this embodiment is put into use, the force exerted by the user stepping on the floor 1 is buffered and released by the damper 3, thus avoiding the problem that the instantaneous force directly acts on the support when the user steps on the floor 1, resulting in a short service life and easy damage of the support.

[0028] In this embodiment, a plurality of fixing through holes are evenly opened on the bottom keel plate 21 at the lower end of the elevated keel 2, and the elevated keel 2 is fixedly installed on the bathroom floor in a nailing and fixing manner.

[0029] As one of the preferred options of this embodiment, the elevated keel 2 includes a bottom keel plate 21, a vertical keel plate 22, and a top keel plate 23. The upper end of the vertical keel plate 22 is integrally connected to the top keel plate 23, the lower end of the vertical keel plate 22 is integrally connected to the bottom keel plate 21, and the top keel plate 23 and the bottom keel plate 21 are parallel to each other. The elevated keel 2 is integrally in an I-shaped.

[0030] Standing feet are further provided downward on both side edges of the bottom keel plate 21 to facilitate the stable and fixed installation of the elevated keel 2; threaded fixing holes are opened on the vertical keel plate 22, and the damper 3 is fixedly connected to the side wall of the vertical keel plate 22 by a bolt fixing connection method to facilitate reducing the height of the elevated layer and increasing the utilization space of the bathroom.

[0031] In this embodiment, when the damper 3 is installed on the side wall of the vertical keel plate 22 and the damper 3 bears the weight of the floor 1 and others, in order to prevent the force from acting on the vertical keel plate 22 to form a bending moment and cause the vertical keel plate 22 to bend and deform, a structural reinforcing rib 24 is provided between the bottom surface of the top keel plate 23 and the side wall of the vertical keel plate 22, and the structural reinforcing rib 24 and the damper 3 are on the same side of the vertical keel plate 22.

[0032] In addition, when the damper 3 is fixedly mounted on the vertical keel plate 22 , a mounting through hole 6 is opened on the top keel plate 23 , and the upper end of the piston rod of the damper 3 passes through the mounting through hole 6 to support the floor 1 .

[0033] A plurality of threaded fixing holes are provided on the vertical keel plate 22 , and the damper 3 is fixedly mounted on the side wall of the vertical keel plate 22 by means of bolt fixing connection.

[0034] In other embodiments, structural reinforcement ribs 24 may also be provided between the side walls of the vertical keel plate 22 and the upper surface of the bottom keel plate 21 to further enhance the bending moment strength of the vertical keel plate 22 and prevent the vertical keel plate 22 from bending and deforming under stress.

[0035] As the second preferred option of this embodiment, a structural cavity 25 is provided on the vertical keel plate 22. Under the premise of ensuring that the overhead keel 2 has the required structural strength, providing the structural cavity 25 on the vertical keel plate 22 can reduce the weight of the overhead keel 2, save installation materials, and reduce costs; at the same time, when the structural cavity 25 is provided on the vertical keel plate 22, the drainage pipe 4 can pass through the structural cavity 25 to extend to various places of the overhead layer, providing convenience for the arrangement of the drainage pipe 4.

[0036] In particular, since the floor 1 is supported by the damper 3, when the floor 1 is subjected to force, the damper 3 will inevitably have a corresponding length change, and the drainage pipe 4 is fixedly connected to the floor 1 at the water outlet 5, which results in that when the floor 1 is subjected to force and inevitably moves up and down, the drainage pipe 4 also has to move up and down synchronously with the floor 1, and the drainage pipe 4 passes through the structural cavity 25 during installation, so the drainage pipe 4 is easy to collide with the vertical keel plate 22 when moving up and down, causing damage to the drainage pipe 4. In this regard, the height of the structural cavity 25 is greater than the diameter of the drainage pipe 4, and the height of the structural cavity 25 is also greater than the sum of the diameter of the drainage pipe 4 and the maximum length change of the damper 3, thereby preventing the drainage pipe 4 from colliding with the vertical keel plate 22 when moving up and down.

[0037] As the third preferred option of this embodiment, the damper 3 adopts a hydraulic damper 3, and the upper end of the piston rod of the damper 3 is integrally fixed with a circular support sheet 7. When the damper 3 is supported and contacted with the floor 1 by the support sheet 7, the contact pressure between the damper 3 and the floor 1 can be reduced, so as to avoid the deformation of the stress bulge at the contact position between the floor 1 and the damper 3 due to excessive contact pressure between the floor 1 and the damper 3. In addition, an adhesive sheet 8 is provided at the upper end of the support sheet 7, and the adhesive sheet 8 is bonded and fixed to the floor 1 and the support sheet 7 by structural adhesive; the damper 3 is fixedly connected to the floor 1 by the adhesive sheet 8, so as to replace the traditional bolt screw nailing fixing method, reduce the damage to the floor 1, and also avoid the gap between the upper end of the damper 3 and the floor 1 caused by not nailing, which leads to the problem of hollow drum feeling and sound when the floor 1 is stepped on.

[0038] It should be particularly noted that when the above-mentioned fixed connection method is used to support the floor 1 using the damper 3, since the damper 3 itself will change in length and stretch or shorten when subjected to force, under the action of the adhesive force, the damper 3 will correspondingly change in length adaptively to avoid separation from the floor 1, rather than being unable to change in length adaptively like a traditional rigid support. The floor 1 and the rigid support cannot be fixed by gluing but can only be fixed by bolts or screws.

[0039] Anything not mentioned above is applicable to the prior art.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them. Although the present invention has been described in detail with reference to the above embodiments, a person skilled in the art should understand that the technical solutions described in the above embodiments can still be modified, or some of the technical features can be replaced by equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
