Description

Technical Field

[0001] This application relates to the field of flooring engineering technology, and in particular to a detachable heavy-duty flooring system. Background Technology

[0002] Currently, in areas with soft soil, concrete is traditionally used to construct the floor. However, on soft foundations, the floor is prone to collapse, either entirely or partially, due to insufficient soil bearing capacity. Furthermore, since concrete floors need to be completely broken up during demolition, the materials cannot be reused, resulting in resource waste. There are areas for improvement. Utility Model Content

[0003] To improve the bearing capacity of soft foundations, this application provides a detachable heavy-duty floor.

[0004] This application provides a detachable heavy-duty flooring solution, which adopts the following technical solution: A detachable heavy-duty floor includes a grid skeleton and a filler for filling the grid skeleton. Multiple grid skeletons are provided. A first connecting structure, a second connecting structure and a fourth connecting structure are provided at the edge of any grid skeleton. Adjacent grid skeletons are connected to each other through the first connecting structure and the third connecting structure to form a detachable planar splice. Adjacent grid skeletons are also connected to each other through the second connecting structure and the fourth connecting structure to form a detachable planar splice.

[0005] By adopting the above technical solution, adjacent grid skeletons can be detachably spliced ​​together through the first and third connecting structures, and adjacent grid skeletons can also be detachably spliced ​​together through the second and fourth connecting structures, thus forming a continuous load-bearing surface layer. This allows the grid skeletons to be quickly disassembled and reused, solving the problem of material waste during the demolition of traditional flooring. It combines construction convenience and environmental protection. At the same time, the rigid support of the grid skeletons enhances the overall bearing capacity of the foundation, avoiding the collapse problem caused by soil settlement in traditional concrete flooring.

[0006] Preferably, the first connecting structure is configured as a first protrusion, and the third connecting structure includes a first sleeve frame, a first insert block and a first latch. The first insert block is disposed on the first sleeve frame, and the first sleeve frame and the first protrusion form a sleeve fit. The first protrusion is provided with a first slot for forming an insertion fit with the first insert block, and the first sleeve frame and the first protrusion are locked together by the first latch.

[0007] By adopting the above technical solution, the first protrusion and the first frame are fitted together, and the first insert and the first slot are plugged in to achieve the initial positioning between adjacent grid skeletons. At the same time, the first locking buckle is used to further enhance the connection strength between adjacent grid skeletons, thereby ensuring the stability and reliability of adjacent grid skeletons when splicing them on the plane and improving the overall structural strength of heavy-duty flooring.

[0008] Preferably, the fourth connecting structure includes a second convex plate, a second protrusion, and a second insert. Both the second insert and the second insert are disposed on the second convex plate. The second connecting structure includes a first convex plate and a limiting structure for limiting the second protrusion on the first convex plate. The first convex plate is provided with a second slot for forming an insertion engagement with the second protrusion and a third slot for forming an insertion engagement with the second insert.

[0009] By adopting the above technical solution, the second protrusion and the second slot are connected to form an insertion fit, and the second plug and the third slot are connected to form an insertion fit, so as to achieve the initial positioning between adjacent grid skeletons. At the same time, the limiting structure limits the second protrusion to prevent the second protrusion from detaching from the first protrusion plate, so that the grid skeleton has multi-directional pull-out resistance when splicing in a plane, and can adapt to the stress requirements under heavy load conditions.

[0010] Preferably, the first latch includes a T-shaped rod and a screwing sleeve for screwing the T-shaped rod. The T-shaped rod is connected to the screwing sleeve. The T-shaped rod passes through the first sleeve frame and the first protrusion in sequence, and the bottom of the T-shaped rod forms an abutting fit with the inner surface of the first protrusion.

[0011] By adopting the above technical solution, the workers drive the T-shaped rod to pass through the first frame and the first protrusion by rotating the screw sleeve, and then rotate it 90 degrees so that the bottom of the T-shaped rod abuts against the inner surface of the first protrusion to form a mechanical lock. This structure is easy to operate and can be quickly disassembled, thus improving construction efficiency.

[0012] Preferably, the limiting structure includes a first wedge block, a connecting spring, and a return spring. The first wedge block has a first wedge surface, and the second insert block has a second wedge block. The second wedge block has a second wedge surface for abutting with the first wedge surface. One end of the connecting spring is connected to the top of the inner wall of the first convex plate, and the other end is connected to the top of the first wedge block. One end of the return spring is connected to the inner side wall of the first convex plate, and the other end abuts with the second wedge block. The first wedge block and the second wedge block are engaged when locked.

[0013] By adopting the above technical solution, when the worker pushes the second insert into the third slot, the first wedge surface of the first wedge block abuts against the second wedge surface of the second insert, so that the second wedge block can gradually push the first wedge block upward. At this time, both the connecting spring and the return spring are compressed. The second wedge block moves forward until the lower surface of the first wedge block abuts against the upper surface of the second insert, and the first wedge block forms a continuous pressing force on the second insert. At this time, the first wedge block and the second wedge block are locked together. At the same time, the return spring can provide a reverse thrust when the second insert block is removed, assisting the second insert block to disengage from the third slot, thus improving the ease of installation and removal of the second insert block and the third slot.

[0014] Preferably, the first connecting structure is provided with multiple intervals, and a first semi-circular ring is formed between adjacent first connecting structures; the third connecting structure is provided with multiple intervals, and a second semi-circular ring is formed between adjacent third connecting structures; a complete drainage hole is formed between the first semi-circular ring and the second semi-circular ring.

[0015] By adopting the above technical solution, a complete drainage hole is formed by splicing the first semi-circular ring between adjacent first connecting structures and the second semi-circular ring between adjacent third connecting structures, thus forming a through drainage channel in the subfloor base and effectively draining the accumulated water from the foundation.

[0016] Preferably, the second connecting structure is provided with multiple intervals, and a third semi-circular ring is formed between adjacent second connecting structures. The fourth connecting structure is provided with multiple intervals, and a fourth semi-circular ring is formed between adjacent fourth connecting structures. A complete drainage hole is formed between the third semi-circular ring and the fourth semi-circular ring.

[0017] By adopting the above technical solution, the third semicircular ring between adjacent second connecting structures and the fourth semicircular ring between adjacent fourth connecting structures are spliced ​​to form a complete drainage hole, which further improves drainage efficiency, prevents foundation softening problems caused by local water accumulation, and enhances the stability of the floor in a humid environment.

[0018] Preferably, the filler can be gravel.

[0019] By adopting the above technical solution, gravel is used as a filler, and the particle size distribution characteristics of gravel are used to form a dense packing structure. The load is transferred through the friction and interlocking force between the particles, thereby improving the bearing capacity of the foundation. At the same time, gravel has good permeability, which can help the drainage holes to accelerate drainage. Moreover, the material is widely available, inexpensive, easy to obtain on site and reuse, and meets the requirements of energy conservation and environmental protection.

[0020] In summary, this application includes at least one of the following beneficial technical effects: 1. Adjacent grid frames are connected to form a detachable planar splice through the first and third connecting structures, and adjacent grid frames can also be connected to form a detachable planar splice through the second and fourth connecting structures, thus forming a continuous load-bearing surface layer. This allows for quick assembly and disassembly of the grid frames and reuse, solving the problem of material waste during the demolition of traditional flooring. It combines construction convenience and environmental protection. At the same time, the rigid support of the grid frames enhances the overall bearing capacity of the foundation, avoiding the collapse problem caused by soil settlement in traditional concrete flooring. 2. The operator drives the T-shaped rod to pass through the first frame and the first protrusion by rotating the screw sleeve, and then rotates it 90 degrees so that the bottom of the T-shaped rod abuts against the inner surface of the first protrusion to form a mechanical lock. This structure is easy to operate and can be quickly disassembled, improving construction efficiency. 3. When the worker pushes the second insert into the third slot, the first wedge surface of the first wedge block abuts against the second wedge surface of the second insert, so that the second wedge block can gradually push the first wedge block upward. At this time, both the connecting spring and the return spring are compressed. The second wedge block moves forward until the lower surface of the first wedge block abuts against the upper surface of the second insert, and the first wedge block forms a continuous pressing force on the second insert. At this time, the first wedge block and the second wedge block are locked together. At the same time, the return spring can provide a reverse thrust when the second insert block is removed, assisting the second insert block to disengage from the third slot, improving the ease of installation and removal of the second insert block and the third slot.

[0023] The following is in conjunction with the appendix Figure 1 -Appendix Figure 5 This application will be described in further detail.

[0024] This application discloses a detachable heavy-duty flooring.

[0025] Reference Figure 1 A detachable heavy-duty floor includes a grid skeleton 1 and a filler. The grid skeleton 1 is rectangular with dimensions of 500mm × 500mm × 40mm. The grid skeleton 1 is made of PP composite material and has regularly distributed hollow grid units 11 inside. Each hollow grid unit 11 has a drainage hole 12. The filler is filled into the hollow grid units 11 used to fill the grid skeleton 1. The filler can be gravel, sand, asphalt, or grass. In this embodiment, the filler is gravel. The gravel layer is compacted by vibration to form a dense structure, which, together with the grid skeleton 1, bears the load and improves the overall bearing capacity of the foundation.

[0026] Reference Figure 1 Multiple mesh skeletons 1 are provided. A first connecting structure 2, a second connecting structure 3, a third connecting structure 4 and a fourth connecting structure 5 are respectively provided on the four edges of any mesh skeleton 1. The third connecting structure 4 is provided on the side of the mesh skeleton 1 away from the first connecting structure 2, and the fourth connecting structure 5 is provided on the side of the mesh skeleton 1 away from the second connecting structure 3.

[0027] Reference Figure 1Adjacent grid frames 1 are connected by a first connecting structure 2 and a third connecting structure 4 to form a detachable longitudinal plane splice, and adjacent grid frames 1 are connected by a second connecting structure 3 and a fourth connecting structure 5 to form a detachable transverse plane splice, thereby forming a continuous floor bearing surface layer. At the same time, the grid frames 1 can be quickly disassembled and reused, solving the problem of material waste during the demolition of traditional flooring.

[0028] Reference Figure 1 Multiple first connection structures 2 are provided on any mesh skeleton 1, and the third connection structure 4 is set according to the position and number of the first connection structure 2. Since the structures and connection methods of adjacent first connection structures 2 and third connection structures 4 are the same, we will now take one set of adjacent first connection structures 2 and third connection structures 4 as an example for explanation.

[0029] Reference Figure 2 and Figure 3 The first connecting structure 2 is configured as a first protrusion 21, which is welded to the longitudinal edge of the mesh skeleton 1. A first slot 211 is provided on the first protrusion 21. The third connecting structure 4 includes a first frame 41, a first insert 42 and a first latch 43. The first frame 41 is welded to the longitudinal edge of the mesh skeleton 1, and the first insert 42 is vertically welded to the first frame 41. The first frame 41 and the first protrusion 21 are respectively provided with reserved holes 212 corresponding to the shape of the T-shaped rod 431.

[0030] Reference Figure 3 and Figure 4 The first latch 43 includes a T-shaped rod 431 and a screw sleeve 432, with the T-shaped rod 431 and the screw sleeve 432 welded together.

[0031] Reference Figure 2 , Figure 3 and Figure 4 When it is necessary to longitudinally splice adjacent grid skeletons 1, the first frame 41 and the first protrusion 21 form a fitting engagement, and the first insert 42 and the first slot 211 form an insertion engagement. The T-shaped rod 431 is then inserted through the reserved holes 212 of the first frame 41 and the first protrusion 21, so that the bottom of the T-shaped rod 431 abuts against the inner surface of the first protrusion 21. Then, the T-shaped rod 431 is rotated 90° by screwing the sleeve 432, thereby completing the mechanical locking between the first frame 41 and the first protrusion 21. This triple structure of fitting, insertion and locking facilitates the installation and disassembly of workers, while ensuring the stability and reliability of adjacent grid skeletons 1 when spliced ​​on the plane, and improving the overall structural strength of the heavy-duty floor.

[0032] Reference Figure 1Multiple second connection structures 3 are provided on any mesh skeleton 1. The fourth connection structure 5 is set according to the position and number of the second connection structures 3. Since the structures and connection methods of adjacent second connection structures 3 and fourth connection structures 5 are the same, we will now take one set of adjacent second connection structures 3 and fourth connection structures 5 as an example for explanation.

[0033] Reference Figure 2 and Figure 3 The second connecting structure 3 includes a first protruding plate 31 and a limiting structure 32. The first protruding plate 31 has an installation groove 311 inside. The first protruding plate 31 is welded to the transverse edge of the mesh frame 1. The first protruding plate 31 has a second slot 312 and a third slot 313. The third slot 313 is connected to the installation groove 311. The fourth connecting structure 5 includes a second protruding plate 51, a second protrusion 52 and a second insert 53. The second protruding plate 51 is welded to the transverse edge of the mesh frame 1. The second insert 53 and the second insert 53 are both vertically welded to the second protruding plate 51.

[0034] Reference Figure 2 and Figure 3 The second slot 312 on the first protrusion 31 has symmetrically formed strip-shaped insert blocks 314. The second protrusion 52 has insert grooves 521 corresponding to the position and number of insert blocks 314. Any insert block 314 and the corresponding insert groove 521 form an insert fit, thereby making the connection between the second protrusion 52 and the second slot 312 more stable.

[0035] Reference Figure 5 The limiting structure 32 includes a first wedge block 321, a connecting spring 322, and a return spring 323. The first wedge block 321 is arranged perpendicular to the insertion direction of the second insert block 53 and is located above the second insert block 53. The bottom of the first wedge block 321 is provided with a first wedge surface 3211. A second wedge block 54 is formed on the side of the second insert block 53 opposite to the second protrusion 52. A second wedge surface 541 is provided on the side of the second wedge block 54 opposite to the second insert block 53. One end of the connecting spring 322 is bonded to the top wall of the mounting groove 311 of the first protrusion plate 31, and the other end is bonded to the top of the first wedge block 321. One end of the return spring 323 is bonded to the inner side wall of the first protrusion plate 31, and the other end forms an abutment fit with the second wedge block 54.

[0036] Reference Figure 2 , Figure 3 and Figure 5When it is necessary to horizontally splice adjacent grid skeletons 1, the second protrusion 52 and the second slot 312 form an insertion engagement, and the embedded block 314 on the second protrusion 52 forms an embedded engagement with the embedded groove 521. The second insert block 53 and the third slot 313 form an insertion engagement, and the first abutting surface of the second wedge block 54 abuts against the second abutting surface of the first insert block 42. Thus, the second wedge block 54 pushes the first wedge block 321 upward to compress the connecting spring 322 until the second insert block 53 is fully inserted. At this time, the return spring 323 is in a compressed state, and the lower surface of the first wedge block 321 abuts against the upper surface of the second insert block 53. The first wedge block 321 forms a continuous pressing force on the second insert block 53, that is, the first wedge block 321 and the second wedge block 54 are locked together and formed a self-locking mechanism.

[0037] Reference Figure 3 and Figure 5 Multiple first wedge blocks 321 located on the same side are horizontally connected by a linkage rod 33. Any first protrusion 21 is welded to the linkage rod 33. When it is necessary to disassemble the adjacent grid skeleton 1 laterally, the worker raises the linkage rod 33, and the linkage rod 33 drives multiple first wedge blocks 321 to rise at the same time. At this time, multiple second inserts 53 located in the grid skeleton 1 are simultaneously disengaged from the third slot 313 under the action of the return spring 323. At this time, the second protrusion 52 is also disengaged from the second slot 312 under the pull of the worker, which improves the convenience of assembly and disassembly.

[0038] Reference Figure 1 A first semi-circular ring 22 is formed between adjacent first connecting structures 2, and multiple third connecting structures 4 are spaced apart. A second semi-circular ring 44 is formed between adjacent third connecting structures 4. The first semi-circular ring 22 and the second semi-circular ring 44 are longitudinally spliced ​​to form a complete drainage hole 12.

[0039] Reference Figure 1 A third semicircular ring 34 is formed between adjacent second connecting structures 3. Multiple fourth connecting structures 5 are spaced apart. A fourth semicircular ring 55 is formed between adjacent fourth connecting structures 5. After being spliced ​​laterally, a complete drainage hole 12 is formed between the third semicircular ring 34 and the fourth semicircular ring 55.

[0040] Reference Figure 1 The drainage holes 12 are distributed in a matrix along the longitudinal and transverse directions of the floor, forming a continuous drainage channel in the floor base layer. This can quickly drain the moisture in the foundation soil, reduce the buoyancy of groundwater on the floor, avoid foundation softening caused by water accumulation, and extend the service life of the floor.

[0041] The implementation principle of this application embodiment is as follows: When longitudinally splicing adjacent grid skeletons 1, the worker first puts the first frame 41 on the first protrusion 21, and at the same time inserts the first insert 42 into the first slot 211. Then, the T-shaped rod 431 is passed through the reserved holes 212 of the first frame 41 and the first protrusion 21 in sequence, and the bottom of the T-shaped rod 431 is pressed against the inner surface of the first protrusion 21. Finally, the T-shaped rod 431 is rotated 90° by screwing the sleeve 432, thereby completing the mechanical locking between the first frame 41 and the first protrusion 21.

[0042] When horizontally splicing adjacent grid skeletons 1, the worker first inserts the second protrusion 52 into the second slot 312, and the embedding block 314 on the second protrusion 52 is embedded into the embedding groove 521. Then, the second insert 53 is gradually inserted into the third slot 313. The first abutting surface of the second wedge 54 abuts against the second abutting surface of the first insert 42, thereby pushing the first wedge 321 upward to compress the connecting spring 322 until the second insert 53 is fully inserted. At this time, the return spring 323 is in a compressed state, and the lower surface of the first wedge 321 abuts against the upper surface of the second insert 53. The first wedge 321 forms a continuous pressing force on the second insert 53, that is, the first wedge 321 and the second wedge 54 are locked together and formed a self-locking mechanism.

[0043] After multiple grid frames 1 are spliced ​​together, the spliced ​​grid frames 1 are installed on the soft foundation. Gravel layers are filled into the hollow grid units 11 of the grid frames 1. The gravel layers are compacted by vibration to form a dense structure, which shares the load with the grid frames 1 and improves the overall bearing capacity of the foundation.

[0044] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
