Description

Technical Field

[0001] The utility model relates to the technical field of building floors, in particular to an assembled box concrete hollow floor. Background Art

[0002] The prefabricated concrete hollow floor is a new type of floor system, following the beamless and multi-ribbed floor systems. It is composed of prefabricated prefabricated boxes and cast-in-place reinforced concrete ribs. The prefabricated boxes are assembled from three parts: a reinforced concrete top and bottom plate, and side plates made of hard material. Cast-in-place ribs are installed between adjacent boxes. The prefabricated boxes are connected to the cast-in-place ribs through extended steel bars anchored in the top and bottom plates.

[0003] In existing assembled box concrete hollow floor slabs, embedded parts are generally provided for hanging objects. For example, Chinese patent document CN207063177U discloses a hanging embedded part for cast-in-place concrete floor slabs, which includes a hook head for hooking the bottom reinforcement, a ring integrally formed with the hook head, a connecting screw arranged between the bottom reinforcement and the formwork, and an inner screw at the bottom of the connecting screw. Through the ring mounted on the connecting screw, and the interactive connection between the inner screw, the connecting screw and the formwork, it can meet the needs of simultaneous drilling during the preparation process of the cast-in-place concrete floor slab, and the subsequent needs of hanging various pipelines such as fire pipes.

[0004] However, there are some defects in the hanging embedded parts for cast-in-place concrete floor slabs:

[0005] (1) The installation accuracy between the components of this device is high, because the installation process involves the combination of multiple parts, including hooking the bottom rib with the hook head, setting the connecting screw with the ring, connecting the inner screw with the connecting screw, and penetrating the template. At the construction site, due to various factors such as differences in workers' operating skills and environmental interference, it is difficult to ensure the installation accuracy between components, which may lead to mismatched threads and loose connections. This will not only increase the time and difficulty of construction, but also easily cause problems in various links, ultimately affecting the stability of the entire embedded part.

[0006] (2) During the concrete pouring process, the cement slurry in the concrete may seep into the gap between the ferrule and the connecting screw, or clog the threads of the inner screw, making it difficult to remove the inner screw and even damaging the embedded parts. Once the embedded parts have problems during use, maintenance and replacement will be very difficult because they are installed inside the concrete floor. It may be necessary to destroy part of the floor structure to repair it, which not only increases costs but also affects the overall performance and service life of the floor. Utility Model Content

[0007] In view of this, the utility model provides an assembly box concrete hollow floor to solve the shortcomings of the existing technology, such as the difficulty in ensuring the installation accuracy of the hanging embedded parts and the susceptibility to the influence of concrete pouring, which makes subsequent maintenance and replacement difficult, thereby providing an assembly box concrete hollow floor.

[0008] The utility model provides an assembly box concrete hollow floor, comprising an assembly box, a wire box and steel bars, wherein the assembly box has a concrete bottom plate with a hole formed thereon; the wire box is a box body with an opening, the opening of the wire box is downwardly arranged in the hole of the concrete bottom plate, and one end of the wire box away from the opening protrudes upward from the concrete bottom plate; the steel bars are arranged on the concrete bottom plate, the steel bars pass through the middle of the wire box, and the bottom of the concrete bottom plate exposes the steel bars through the opening of the wire box.

[0009] The combination of an assembly box, a junction box, and rebar creates a hollow floor structure with built-in rebar hanging embedded parts. This structure makes floor construction more modular and improves construction efficiency. The use of a hollow floor reduces the floor's deadweight, lowering the overall building load. The built-in rebar hanging embedded parts can meet the needs of later ceiling installation of large equipment. Furthermore, the combination of the junction box and assembly box eliminates the need for separate installation of the junction box, thereby reducing construction difficulty. The junction box protrudes upward from the concrete floor, away from the opening, facilitating subsequent wiring operations and improving construction convenience. When maintenance is required, it can be easily accessed from the opening, thus reducing maintenance difficulty and cost. Furthermore, the rational placement of the junction box ensures safe and standardized wiring installation, avoiding potential safety hazards. The junction box opening is positioned downward within the hole in the concrete floor of the assembly box, making the junction box installation more stable and less prone to displacement, thereby ensuring the installation accuracy of the rebar hanging embedded parts and reducing subsequent problems. In addition, by passing the steel bars through the middle of the wire box and exposing the steel bars through the opening of the wire box at the bottom of the concrete base plate, the interior of the wire box will not be affected when the concrete is poured and fixed, thereby ensuring the use requirements of the steel bar hanging embedded parts inside the wire box, and facilitating the operation of steel bar welding or binding when the floor is connected to other structures, thereby ensuring the overall performance of the floor and the service life of the steel bar hanging embedded parts.

[0010] Optionally, the present invention provides an assembly box concrete hollow floor slab, further comprising a wire pipe, wherein the wire pipe is arranged above the concrete bottom plate and passes through the wire box.

[0011] By placing conduits through junction boxes above the concrete slab, a clear and defined path for laying electrical lines can be provided, ensuring a more orderly routing of the wiring and avoiding the confusion and safety hazards caused by haphazard wiring. During construction, conduits can be installed after the concrete slab is laid. Construction workers, based on design requirements, accurately thread the conduits through the junction boxes to connect and extend the wiring. Furthermore, if the wiring needs to be inspected or replaced later, the conduit installation facilitates maintenance, requiring no damage to the concrete structure; access can be performed simply by opening the conduit, significantly reducing maintenance costs and time.

[0012] Optionally, the utility model provides an assembly box concrete hollow floor slab, wherein the wire conduit is located above the steel bars.

[0013] By placing the wire conduit above the steel bars, construction workers can perform wiring operations more intuitively and conveniently, thereby improving construction efficiency and reducing rework caused by inaccurate wire conduit positioning. At the same time, it can avoid direct pressure of the steel bars on the wire conduit during construction and subsequent use, reducing the risk of damage to the wire conduit. Furthermore, when pouring concrete, the wire conduit is placed above the steel bars. The steel bars can act as a barrier to reduce the impact of concrete aggregate on the wire conduit, thereby protecting the integrity of the wire conduit. In addition, during later maintenance, the wire conduit is easier to locate and access above the steel bars, thereby saving maintenance time and costs. When installing the suspended ceiling, the position of the wire conduit above will not affect the use of the space below, making the overall spatial layout more reasonable.

[0014] Optionally, the utility model provides an assembly box concrete hollow floor, wherein at least two wire tubes are passed through the wire box in parallel and symmetrically with respect to the steel bars.

[0015] By symmetrically placing the wire conduits parallel to the rebar on the wire box, the layout of the wire conduits can be made more regular and orderly, preventing the messy distribution of the wire conduits from affecting subsequent maintenance and inspection work. At the same time, the design of at least two wire conduits running in parallel and symmetrically can form a more uniform support structure around the wire box. When the floor is subjected to upper loads, the wire conduits and the wire box work together to better disperse stress and improve the overall mechanical properties of the floor. In addition, the parallel and symmetrical wire conduits can also increase the stability of the wire box, making it less likely to shift or deform when subjected to external forces, and facilitate the separate layout of different types of lines to avoid interference between lines.

[0016] Optionally, the utility model provides an assembly box concrete hollow floor, wherein the gap between the wire box and the hole at the bottom of the concrete is filled with plain concrete.

[0017] By using plain concrete to seal the gaps between the holes at the bottom of the concrete, the connection between the junction box and the concrete base plate can be tightened, thereby strengthening the integrity of the entire floor structure. This prevents cracks or deformation caused by weak local connections when the floor is subjected to various loads, thereby improving the reliability of the embedded steel bar hanging parts and the overall stability of the floor. At the same time, plain concrete can effectively seal the gap between the junction box and the concrete base plate, preventing the infiltration of moisture, gas, or other harmful substances, thereby ensuring the normal use of the embedded steel bar hanging parts and extending their service life. In addition, the rebar at the bottom of the concrete base plate is exposed through the junction box opening. Filling with plain concrete prevents the rebar from being directly exposed to the air, protecting the rebar from oxidation and corrosion, and further ensuring the service life of the embedded steel bar hanging parts.

[0018] Optionally, the utility model provides an assembled box concrete hollow floor slab, wherein the strength grade of the plain concrete is C30.

[0019] By setting the strength grade of plain concrete to C30, the overall stability of the floor can be effectively guaranteed. C30 plain concrete has high compressive strength and can withstand greater pressure. In the assembled box concrete hollow floor, it can bear all kinds of loads transmitted from the superstructure, ensuring that the floor will not be excessively deformed or damaged due to pressure during use. At the same time, C30 plain concrete has certain wear and corrosion resistance. In long-term use, it can withstand the influence of external environmental factors, reduce floor structural problems caused by concrete damage, and thus extend the service life of the floor. In addition, the mix ratio of C30 plain concrete is relatively mature and stable, making it easy to mix and pour during the construction process, which can ensure the density of the concrete. Moreover, the raw material cost of C30 plain concrete is relatively reasonable. While meeting the structural strength requirements of the floor, it will not excessively increase the project cost.

[0020] Optionally, the utility model provides an assembled box concrete hollow floor slab, wherein the steel bars are plain round steel bars.

[0021] By setting up plain round steel bars, the construction process can be made more convenient and efficient, thereby reducing processing time and labor costs. The surface of plain round steel bars is smooth, and it is easy to bend, cut, and perform other operations during the processing process, which can better adapt to the design requirements of different floor slabs. At the same time, plain round steel bars are inserted into the wire box and fixed together with the assembly box and the wire box by pouring concrete. The friction between the plain round steel bars and the concrete ensures the bonding between the steel bars and the concrete to a certain extent, thereby ensuring the overall performance of the floor slab. In addition, the surface of plain round steel bars is smooth, and it is not easy to accumulate corrosive media. It has good corrosion resistance. Even in a humid environment or in the presence of corrosive media, it can better maintain its mechanical properties and extend the service life of the floor slab. Moreover, the production process of plain round steel bars is relatively simple and the cost is low. Under the premise of ensuring the safety and reliability of the floor slab structure, the use of plain round steel bars can reduce costs.

[0022] Optionally, the present invention provides an assembly box concrete hollow floor, the assembly box further comprising: a top plate and side plates, the bottom, side plates and top are combined to form a plurality of box structures, and cast-in-situ rib beams are arranged between adjacent boxes.

[0023] On the one hand, by attaching a top plate and side panels to the assembly box and combining them with a concrete bottom plate to form a box structure, the box-shaped concrete hollow-core floor provides a stable and enclosed space, thereby enhancing the overall performance of the floor and better bearing vertical and horizontal loads. Furthermore, the materials of the top and side panels can be selected according to project requirements to meet different scenarios and effectively share the floor load, thereby improving load-bearing capacity. Furthermore, the prefabricated top and side panels can be standardized in the factory to ensure quality and dimensional accuracy, and can be simply assembled on site, thereby improving construction efficiency and shortening the construction period. Furthermore, the installation of cast-in-place rib beams between adjacent boxes effectively improves the overall performance and rigidity of the floor, ensuring a more secure and reliable connection between the rib beams and the assembly box, and preventing cracks and deformation during use, thereby enhancing the safety and reliability of the floor. Furthermore, for long-span floor structures, cast-in-place rib beams can reduce deflection and deformation of the floor to meet operational requirements. At the same time, pipeline channels can be reserved inside the cast-in-place rib beams to facilitate the layout of electrical, water supply and drainage pipelines, and the cast-in-place rib beams can be flexibly designed according to the shape and layout of the building to adapt to the structural requirements of complex buildings, thereby achieving good structural performance of the floor.

[0024] Optionally, the present invention provides an assembled box concrete hollow floor, wherein the side panels are made of wooden boards, the thickness of the wooden boards is 10 mm, and the thickness of the concrete bottom plate is 50 mm.

[0025] By using wood for the side panels of the assembly box, the overall production cost of the box can be reduced. Since wood is easy to procure and delivered to the construction site in a timely manner, the project schedule is not affected by material shortages. The wood's flexibility also allows it to easily adapt to the box's changing shape during installation, facilitating its integration with other components and improving construction efficiency. Furthermore, the wood can be cut and processed as needed to accommodate various sizes and shapes of assembly box side panels, thus enhancing construction flexibility. First, the 10mm-thick wood side panels of this floor slab are relatively thin, making them easier to connect and secure to other components. This thinness allows them to meet the support requirements of the assembly box side panels without adding excessive load to the overall floor structure. Second, the 50mm-thick concrete base slab provides a high load-bearing capacity, capable of withstanding the infill within the assembly box and the loads from above, thereby ensuring the structural stability of the floor. The 50mm-thick base slab effectively blocks sound transmission, reducing noise interference between upper and lower floors and improving the comfort of the subsequent living or office environment.

[0031] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0032] The following combination Figures 1 to 2 , describing the embodiments of the present utility model.

[0033] like Figure 1 As shown, a specific implementation of the assembly box concrete hollow floor provided in this embodiment includes an assembly box, a wire box 3 and steel bars 4. The assembly box has a concrete base plate 1 with a hole 2 formed thereon; the wire box 3 is a box body with an opening, the opening of the wire box 3 is downwardly arranged in the hole 2 of the concrete base plate 1, and the end of the wire box 3 away from the opening protrudes upward from the concrete base plate 1; the steel bars 4 are arranged on the concrete base plate 1, the steel bars 4 pass through the middle of the wire box 3, and the bottom of the concrete base plate 1 is exposed to the steel bars 4 through the opening of the wire box 3.

[0034] This embodiment adopts a combination of an assembly box, a junction box 3 and steel bars 4, thereby forming a hollow floor structure with built-in steel bars 4 for hanging embedded parts. This makes the construction of the floor more modular, thereby improving construction efficiency. The use of a hollow floor also reduces the weight of the floor and reduces the overall load of the building. By hanging embedded parts with built-in steel bars 4, the need to install large equipment on the ceiling in the later stage can also be met. At the same time, the clever combination of the junction box 3 and the assembly box reduces the process of installing the junction box 3 separately during the construction process, reducing the difficulty of construction. The end of the junction box 3 away from the opening protrudes upward from the concrete base plate 1, which also facilitates subsequent wiring operations, thereby improving the convenience of construction. When later maintenance is required, it can be operated more conveniently from the opening, reducing the difficulty and cost of maintenance. In addition, the reasonable setting of the junction box 3 also makes the laying of wires more standardized and safe, avoiding the safety hazards caused by the random arrangement of wires in concrete. Furthermore, by setting the opening of the wire box 3 downward in the hole 2 of the concrete base plate 1 of the assembly box, the installation of the wire box 3 can be made more stable and not easy to shift, thereby effectively ensuring the installation accuracy of the embedded parts of the steel bar 4, thereby reducing subsequent problems caused by inaccurate installation positions. In addition, by passing the steel bar 4 through the middle of the wire box 3 and exposing the steel bar 4 at the bottom of the concrete base plate 1 through the opening of the wire box 3, when the wire box 3 is cast and fixed with concrete, the interior of the wire box 3 will not be affected by the casting, thereby ensuring the use requirements of the embedded parts of the steel bar 4 inside the wire box 3, and facilitating the welding or tying operations of the steel bar 4 when the floor is connected to other structures, thereby ensuring the overall performance of the floor and the service life of the embedded parts of the steel bar 4.

[0035] like Figure 1 As shown, this is a specific implementation of the assembled box concrete hollow floor provided in this embodiment, which also includes a wire pipe 5. The wire pipe 5 is arranged above the concrete bottom plate 1 and passes through the wire box 3.

[0036] This embodiment, by placing the wire conduit 5 through the junction box 3 and above the concrete base slab 1, provides a clear path for laying the electrical lines, making the routing of the electrical lines clearer and more orderly while avoiding the confusion and safety hazards that may arise from the random arrangement of the electrical lines. Furthermore, during construction, the wire conduit 5 can be installed after the concrete base slab 1 is laid. Construction personnel can accurately pass the wire conduit 5 through the junction box 3 according to design requirements to connect and extend the lines. Furthermore, if the lines need to be inspected or replaced later, the placement of the wire conduit 5 makes maintenance more convenient. No need to damage the concrete structure; simply open the wire conduit 5 to perform the operation, significantly reducing maintenance costs and time.

[0037] like Figure 1 As shown, this is a specific implementation of the assembled box concrete hollow floor provided in this embodiment, and the wire pipe 5 is located above the steel bar 4.

[0038] By placing the conduit 5 above the rebar 4, this embodiment makes laying the conduit 5 more intuitive and convenient, allowing construction workers to more accurately perform wiring operations and reducing rework caused by inaccurate placement of the conduit 5, thereby improving construction efficiency. Furthermore, since the rebar 4 is subject to significant pressure and stress during construction and subsequent use, placing the conduit 5 above the rebar 4 effectively prevents direct pressure from the rebar 4 on the conduit 5, reducing the risk of damage. Furthermore, during concrete pouring, placing the conduit 5 above the rebar 4 acts as a barrier, reducing the impact of the concrete aggregate on the conduit 5 and thus protecting its integrity. Furthermore, if a conduit 5 malfunctions and requires repair, it is easier to locate and access above the rebar 4. Repair personnel can quickly locate and address the conduit 5 issue without having to dismantle a large amount of rebar 4, thus saving repair time and costs. Furthermore, when installing a suspended ceiling, the conduit 5's position above the rebar 4 does not interfere with the use of the space below, thus improving the overall spatial layout.

[0039] like Figure 2 As shown, this is a specific implementation of the assembled box concrete hollow floor provided in this embodiment, in which at least two wire tubes 5 are symmetrically provided on the wire box 3 in parallel with the steel bars 4 .

[0040] This embodiment arranges the wire conduits 5 symmetrically and parallel to the steel bars 4 on the wire box 3, making the layout of the wire conduits 5 more regular and orderly, thus avoiding the disorderly distribution of the wire conduits 5 that affects subsequent maintenance and inspection work. At the same time, the design of at least two wire conduits 5 arranged in parallel and symmetrically allows a relatively uniform support structure to be formed around the wire box 3. When the floor is subjected to upper loads, the wire conduits 5 and the wire box 3 work together to better disperse stress and improve the overall mechanical properties of the floor. In addition, the parallel and symmetrical arrangement of the wire conduits 5 can also increase the stability of the wire box 3, making it less likely to be displaced or deformed when subjected to external forces. It also facilitates the separate arrangement of different types of lines to avoid mutual interference between the lines.

[0041] like Figure 1 and Figure 2 As shown, this is a specific implementation of the assembled box concrete hollow floor provided in this embodiment, and the gap between the junction box 3 and the hole 2 of the concrete bottom plate 1 is filled with plain concrete 6.

[0042] In this embodiment, the gaps between the holes 2 of the concrete base plate 1 are sealed with plain concrete 6, so that the connection between the junction box 3 and the concrete base plate 1 is tighter, thereby enhancing the integrity of the entire floor structure. This helps the floor to avoid cracks or deformations due to loose local connections when bearing various loads, thereby improving the reliability of the embedded parts for hanging steel bars 4 and the overall stability of the floor. At the same time, the plain concrete 6 can effectively seal the gaps between the junction box 3 and the concrete base plate 1 to prevent the infiltration of moisture, gas or other harmful substances, thereby ensuring the normal use and long-term life of the embedded parts for hanging steel bars 4. In addition, the bottom of the concrete base plate 1 exposes the steel bars 4 through the opening of the junction box 3. Filling with plain concrete 6 can prevent the steel bars 4 from being directly exposed to the air, protecting the steel bars 4 from oxidation and corrosion, and further ensuring the service life of the embedded parts for hanging steel bars 4.

[0043] like Figure 1 and Figure 2 As shown in FIG, this is a specific implementation of the assembled box concrete hollow floor provided in this embodiment, and the strength grade of the plain concrete 6 is C30.

[0044] This embodiment effectively ensures the overall stability of the floor by setting the strength grade of the plain concrete 6 to C30. Because C30 plain concrete 6 has a high compressive strength and can withstand significant pressure, it can withstand various loads transmitted from the superstructure in the assembled box concrete hollow floor, ensuring that the floor will not suffer excessive deformation or damage due to pressure during use. Furthermore, C30 plain concrete 6 possesses certain wear and corrosion resistance, and can resist the influence of external environmental factors during long-term use, reducing floor structural problems caused by concrete damage, thereby extending the service life of the floor. Furthermore, the mix ratio of C30 plain concrete 6 is relatively mature and stable, making it easy to mix and pour during construction, ensuring the compactness of the concrete. Furthermore, the raw material cost of C30 plain concrete 6 is relatively reasonable, meeting the structural strength requirements of the floor without excessively increasing project costs.

[0045] Of course, the above description is not restrictive. In some alternative embodiments, the plain concrete 6 of the C30 strength grade can also be replaced with plain concrete 6 of C35 or C25. C35 plain concrete 6 has higher compressive strength and can withstand greater loads. In some buildings that have higher requirements for the bearing capacity of the floor, the use of C35 plain concrete 6 can better meet the engineering needs. Although the compressive strength of C25 plain concrete 6 is relatively low, in some buildings with less high load requirements, C25 plain concrete 6 can reduce the engineering cost while ensuring the safety of the floor structure. The mix ratio of C25 plain concrete 6 is also relatively mature, and it is easy to operate during the construction process, and the pouring quality of the concrete can also be guaranteed. When selecting alternative materials, it is necessary to comprehensively consider factors such as the use requirements of the building, engineering costs, and construction conditions to ensure the structural safety and stable performance of the floor.

[0046] like Figure 1 and Figure 2 As shown in FIG, a specific implementation of the assembled box concrete hollow floor provided in this embodiment, the steel bar 4 is a plain round steel bar.

[0047] This embodiment makes the construction process more convenient and efficient by arranging plain round steel bars, thereby reducing processing time and labor costs. Since the surface of the plain round steel bars is smooth, they are easy to bend, cut, and perform other operations during the processing, thereby being able to better adapt to the design requirements of different floor coverings. At the same time, the plain round steel bars are interspersed and arranged in the wire box 3, and are fixed by pouring concrete with the assembly box and the wire box 3. The friction between the plain round steel bars and the concrete can also ensure the bonding effect between the steel bars 4 and the concrete to a certain extent, thereby ensuring the overall performance of the floor covering. At the same time, the surface of the plain round steel bars is smooth, and it is not easy to accumulate corrosive media. It has good corrosion resistance. Even in a humid environment or in the presence of corrosive media, the plain round steel bars can better maintain their mechanical properties and extend the service life of the floor covering. In addition, the production process of the plain round steel bars is relatively simple and the cost is low. Under the premise of ensuring the safety and reliability of the floor covering structure, the use of plain round steel bars can reduce costs.

[0048] This is a specific implementation of the assembly box concrete hollow floor provided in this embodiment. The assembly box also includes a top plate and side plates. The bottom, side plates and top are combined to form multiple box structures, and cast-in-situ rib beams are set between adjacent boxes.

[0049] On the one hand, this embodiment provides a stable and enclosed space for the hollow concrete floor of the assembly box by arranging a top plate and side plates on the assembly box, which are combined with the concrete bottom plate 1 to form a box structure. This complete box structure helps to enhance the overall performance of the floor, enabling it to better withstand various vertical and horizontal loads. At the same time, the top plate and side plates can be selected from suitable materials according to specific engineering requirements, so as to meet the needs of different scenarios and effectively share the load on the floor, thereby improving the bearing capacity of the floor. In addition, the prefabricated top plate and side plates can be standardized in the factory, thereby ensuring the quality and dimensional accuracy of the product. Only simple assembly is required at the construction site, thereby improving construction efficiency and shortening the construction period. On the other hand, by arranging cast-in-place rib beams between adjacent boxes of this embodiment, the integrity and rigidity of the floor can be effectively improved. The connection between the rib beams and the assembly box is firm and reliable, which can ensure that the floor will not crack or deform during use, thereby improving the safety and reliability of the floor and enabling it to better resist external forces. Furthermore, for long-span floor structures, the use of cast-in-place ribs can effectively reduce deflection and deformation to meet operational requirements. Furthermore, the cast-in-place ribs provide internal channels for various pipelines, facilitating the layout of electrical, water supply, and drainage lines. Furthermore, the cast-in-place ribs can be flexibly designed to suit the shape and layout of the building, adapting to various complex structural requirements and ultimately achieving excellent structural performance.

[0050] In the specific implementation of the assembled box concrete hollow floor provided in this embodiment, the side panels are made of wooden boards with a thickness of 10 mm, and the thickness of the concrete bottom plate 1 is 50 mm.

[0051] By using wood for the side panels of the assembly box, this embodiment reduces the overall production cost of the assembly box. Because wood is easy to purchase and deliver to the construction site in a timely manner, project progress is ensured to be unaffected by material shortages. The wood's flexibility makes it easier to adapt to the changing shape of the assembly box during installation, facilitating assembly and installation with other components, thereby improving construction efficiency. Furthermore, the wood can be cut and processed as needed to accommodate the various sizes and shapes of the assembly box side panels, thereby increasing construction flexibility. First, the floor slab utilizes 10 mm thick wood for the side panels, which is relatively thin and easier to connect and secure to other components. This thinness allows for the support requirements of the assembly box side panels without adding excessive load to the overall floor structure. Second, the floor slab utilizes a 50 mm thick concrete base plate (1), which has a high load-bearing capacity and can withstand the filler material inside the assembly box as well as the load from above, thereby ensuring the structural stability of the floor. Furthermore, the 50 mm thick base plate effectively blocks sound transmission, reducing noise interference between upper and lower floors and improving the comfort of the subsequent living or office environment.

[0052] Of course, the above description is not restrictive. In some alternative embodiments, the thickness of the wooden board and the concrete base plate 1 can be adjusted according to actual labor needs, but it is also necessary to comprehensively consider factors such as the building's use requirements, project costs and construction conditions to ensure the structural safety and stable performance of the floor.

[0053] Although the embodiments of the present invention have been described with reference to the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations shall fall within the scope defined by the appended claims.
