Description

Technical Field

[0001] This application relates to the field of flooring technology, and in particular to a crack-resistant and wear-resistant flooring structure. Background Technology

[0002] Currently, the floor is the part of the ground floor room that comes into contact with the soil layer. It bears the load of the ground floor room and is required to have a certain strength and rigidity, as well as moisture-proof, waterproof, heat-insulating and wear-resistant properties. The existing floor structure is made of steel frame and concrete pouring.

[0003] The existing technical solution mentioned above has the following defects: multiple steel bars in the same direction are connected by binding with iron wire. During long-term use, the binding of the steel bars in the same direction is prone to loosening, which makes the floor structure prone to cracking. Utility Model Content

[0004] This application provides a crack-resistant and wear-resistant floor structure to more firmly connect the reinforcing bars in the same direction and reduce the possibility of cracking in the floor structure.

[0005] The above-mentioned technical objective of this application is achieved through the following technical solution: A crack-resistant and wear-resistant flooring structure includes a first concrete base layer at the bottom, a second concrete base layer above the first concrete base layer, a steel reinforcement frame within the second concrete base layer, and a connecting structure connecting adjacent steel reinforcement frames. The steel reinforcement frame is a grid-like frame composed of steel bars and is square in shape. The connecting structure includes an anchor rod vertically installed within the first concrete base layer with its upper end located within the second concrete base layer. A connecting plate is fixedly connected to the upper end of the anchor rod, and the surface of the connecting plate is fixedly connected to the upper end surface of the anchor rod. Both ends of the connecting plate facing away from the anchor rod are hinged to rotating plates via hinge seats. The rotating plates can fix the edge steel bars of two adjacent steel reinforcement frames between the rotating plates and the surface of the connecting plate at both ends of the connecting plate.

[0006] By adopting the above technical solution, and by setting up a first concrete cushion layer, a second concrete cushion layer, a steel reinforcement frame, and a connecting structure, the connecting structure includes an anchor rod vertically installed in the first concrete cushion layer with its upper end located in the second concrete cushion layer, a connecting plate fixed to the upper end of the anchor rod, and a rotating plate hinged at both ends of the connecting plate away from the anchor rod surface through a hinge seat. This allows the floor structure to form a layered support system. The first concrete cushion layer can level and isolate the foundation, the second concrete cushion layer provides a foundation for the floor surface construction, and the steel reinforcement frame can enhance the tensile and bearing capacity of the second concrete cushion layer. The connecting structure is fixed in position by the anchor rod, and the edge steel bars of the adjacent steel reinforcement frames are fixed between the two by the connecting plate and the rotating plate, realizing a firm connection between the adjacent steel reinforcement frames and reducing the possibility of cracking of the floor structure due to loose steel reinforcement connections.

[0007] Optionally, the connecting plate has two connecting grooves spaced apart from the anchor rod on its surface. The connecting grooves are connected to the side wall of the connecting plate and are adapted to the reinforcing bars that make up the reinforcing frame. The reinforcing bars of the reinforcing frame can be placed in the connecting grooves, and the rotating plate surface can fit against the connecting plate surface.

[0008] By adopting the above technical solution, the rotating plate can fit with the connecting plate by opening the connecting groove, which allows the edge steel bars of the adjacent steel frame to be stably placed in the connecting groove. The connecting groove is used to initially limit the steel bars, and then the rotating plate fits with the connecting plate to further fix the steel bars, thereby improving the stability of the connection between adjacent steel frames and enabling the steel frame to transmit stress more stably when under load.

[0009] Optionally, a pebble layer is provided on the side of the first concrete cushion layer away from the second concrete cushion layer.

[0010] By adopting the above technical solution and setting up a pebble layer, the large particle size and high strength of the pebble layer can be utilized to provide a solid and uniform support foundation for the first concrete cushion layer. At the same time, the large pores of the pebble layer can form drainage channels to divert moisture in the foundation, reduce the impact of water seepage upward on the upper cushion layer, and evenly distribute the load transmitted from the upper layer to the foundation, thus optimizing the stress state of the foundation.

[0011] Optionally, a PE film is provided between the pebble layer and the first concrete cushion layer, and between the first concrete cushion layer and the second concrete cushion layer.

[0012] By adopting the above technical solution and setting a PE film, the rigid bond between adjacent sub-layers can be severed, allowing the first and second concrete sub-layers to shrink and deform independently. This avoids the shrinkage of one sub-layer affecting the other, thereby reducing the possibility of cracks in the sub-layers due to shrinkage constraints. At the same time, the PE film can also help block some water penetration.

[0013] Optionally, the steel frame is provided in two layers at intervals, with the two layers of steel frames arranged one above the other and connected by steel bars. The two layers of steel frames constitute a steel structure. Multiple adjacent steel structures are provided in the second concrete pad layer, and two adjacent frame structures are connected by a connecting structure.

[0014] By adopting the above technical solution, and by setting up two layers of steel reinforcement frames, and setting up multiple adjacent steel reinforcement structures connected by a connecting structure in the second concrete cushion layer, the three-dimensionality and integrity of the steel reinforcement support in the second concrete cushion layer can be improved. When the second concrete cushion layer is subjected to load, the stress can be transferred more comprehensively through the two layers of steel reinforcement frames. The connection of multiple steel reinforcement structures can also expand the stress transfer range, further improving the load-bearing capacity and deformation resistance of the floor structure.

[0015] Optionally, the end face of the rotating plate near the hinge seat is machined to form a protruding arc surface.

[0016] By adopting the above technical solution, the protruding arc surface formed by machining the rotating plate close to the end face of the hinge seat can reduce the frictional resistance and jamming phenomenon between the rotating plate and the hinge seat during the rotation of the rotating plate around the hinge seat, making the rotation operation of the rotating plate smoother and making it easier for operators to quickly attach the rotating plate to the connecting plate to complete the fixing operation of the steel bars.

[0017] Optionally, the rotating plate has a through hole on the plate surface away from the hinge seat that connects the two plate surfaces. Two threaded holes are opened at intervals between the two connecting grooves on the plate surface of the connecting plate. The threaded holes correspond to the positions of the through holes. When the rotating plate fixes the steel bars that make up the steel frame, the rotating plate is fixed by inserting bolts into the through holes and threading them into the threaded holes.

[0018] By adopting the above technical solution, through holes and threaded holes are opened, and bolts are inserted into the through holes and threadedly connected to the threaded holes. After the rotating plate is attached to the connecting plate to fix the reinforcing bars, the rotating plate and the connecting plate can be firmly locked together by bolts to prevent the rotating plate from loosening and causing the reinforcing bars to shift. At the same time, the bolt connection method can also improve the efficiency of reinforcing bar installation and ensure the reliability of the connection between adjacent reinforcing bar frames.

[0019] Optionally, the through hole is a countersunk hole.

[0020] By adopting the above technical solution, and by setting the through hole as a countersunk hole, the bolt head can be embedded in the countersunk hole when the bolt is inserted into the through hole and connected to the threaded hole, thereby reducing the interference of the bolt head on the second concrete cushion layer pouring process.

[0021] In summary, this application has the following technical effects: 1. By setting up a first concrete cushion layer, a second concrete cushion layer, a steel reinforcement frame, and a connecting structure, the connecting structure includes an anchor rod vertically installed in the first concrete cushion layer with its upper end located in the second concrete cushion layer, a connecting plate fixed to the upper end of the anchor rod, and a rotating plate hinged at both ends of the connecting plate away from the anchor rod plate surface through a hinge seat. This allows the floor structure to form a layered support system. The first concrete cushion layer can level and isolate the foundation, the second concrete cushion layer provides a foundation for the floor surface construction, and the steel reinforcement frame can enhance the tensile and bearing capacity of the second concrete cushion layer. The connecting structure is fixed in position by the anchor rod, and the edge steel bars of the adjacent steel reinforcement frames are fixed between the two by the connecting plate and the rotating plate, so as to achieve a firm connection between the adjacent steel reinforcement frames and reduce the possibility of cracking of the floor structure due to loose steel reinforcement connection. 2. By setting up two layers of steel reinforcement frames and setting up multiple adjacent steel reinforcement structures connected by a connecting structure in the second concrete cushion layer, the three-dimensionality and integrity of the steel reinforcement support in the second concrete cushion layer can be improved. When the second concrete cushion layer is subjected to load, the stress can be transferred more comprehensively through the two layers of steel reinforcement frames. The connection of multiple steel reinforcement structures can also expand the stress transfer range, further improving the load-bearing capacity and deformation resistance of the floor structure. 3. By setting up a PE membrane, the rigid bond between adjacent subfloor layers can be severed, allowing the first and second concrete subfloor layers to shrink and deform independently. This avoids the shrinkage of one subfloor layer affecting the other, thereby reducing the possibility of cracks in the subfloor layers due to shrinkage constraints. At the same time, the PE membrane can also help block some water penetration. Attached Figure Description

[0024] The present application will be further described in detail below with reference to the accompanying drawings.

[0025] This application discloses a crack-resistant and wear-resistant flooring structure, referring to... Figure 1 and Figure 2 The ground structure includes a pebble layer 1 at the bottom, a first concrete pad 2 on top of the pebble layer 1, a second concrete pad 3 on top of the first concrete pad 2, a steel frame 4 inside the second concrete pad 3, and a connecting structure 5 connecting the steel frame 4. The pebble layer 1 is laid at the bottom of the excavation from the construction surface to a certain depth. The pebble layer 1 optimizes the foundation stress, provides efficient drainage, and stabilizes the foundation, providing a solid, dry, and uniform support base for the upper concrete pad and structural layers.

[0026] Combination Figure 1 and Figure 2The first concrete subbase 2 is laid on top of the pebble layer 1. The first concrete subbase 2 is made of poured concrete and levels and compacts the foundation, isolating it from substances such as salt, alkali, and moisture, and protecting the second concrete subbase 3. The second concrete subbase 3 is also made of poured concrete and provides a smooth base surface for subsequent floor surface construction, enhancing the floor strength. A PE film 21 is installed between the pebble layer 1, the first concrete subbase 2, and the second concrete subbase 3. The PE film 21 allows the first and second concrete subbases 2 and 3 to shrink independently, reducing the possibility of one layer shrinking and causing the other to crack.

[0027] Combination Figure 1 and Figure 2 The steel reinforcement frame 4 is a grid-like frame composed of multiple steel bars tied together. The steel reinforcement frame 4 is square and has two layers spaced apart. The two layers of steel reinforcement frame 4 are connected by vertical steel bars. The two layers of steel reinforcement frame 4 constitute a steel reinforcement structure. Multiple steel reinforcement structures are set in the second concrete pad 3. The multiple steel reinforcement structures are connected by the connecting structure 5.

[0028] Combination Figure 1 and Figure 2 The connecting structure 5 includes an anchor rod 51 vertically installed in the first concrete pad 2, a connecting plate 52 installed at the end of the anchor rod 51, and a rotating plate 53 rotatably installed on the connecting plate 52. The anchor rod 51 is cylindrical, with its lower end penetrating the first concrete pad 2 and its upper end protruding from the upper surface of the first concrete pad 2 and the PE film 21 between the first concrete pad 2 and the second concrete pad 3, and located within the second concrete pad 3. The connecting plate 52 is a strip plate. The surface of the connecting plate 52 is fixed to the upper end face of the anchor rod 51. The upper end face of the anchor rod 51 is fixed to the middle of the surface of the connecting plate 52. Two connecting grooves 521 are opened at intervals on the surface of the connecting plate 52 away from the anchor rod 51. The connecting grooves 521 are strip-shaped and connect the two side walls of the connecting plate 52. The length direction of the connecting grooves 521 is perpendicular to the length direction of the connecting plate 52. The connecting grooves 521 are adapted to the steel bars that make up the steel frame 4. The adjacent edge steel bars of the lower steel frame 4 of two adjacent steel structures are placed in the connecting grooves 521. The connecting plate 52 connects the two steel structures, reducing the possibility of ground cracking caused by the separation of the steel frame 4. The anchor rod 51 extends into the first concrete pad 2 and can fix the position of the steel frame 4.

[0029] Combination Figure 1 and Figure 2Hinges 522 are provided at both ends of the connecting plate 52 away from the anchor rod 51. Each hinge 522 consists of two opposing and spaced square plates. The sidewalls of the square plates are fixed to the surface of the connecting plate 52, and the surface of the square plates of the hinge 522 is parallel to the sidewalls of the connecting plate 52. A rotating plate 53 is rotatably mounted on one end of each of the two square plates of the hinge 522 via a hinge shaft. The surface of the rotating plate 53 can fit against the surface of the connecting plate 52 to fix the reinforcing bar located in the connecting groove 521. When the surface of the rotating plate 53 fits against the surface of the connecting plate 52, the length direction of the rotating plate 53 is parallel to the length direction of the connecting plate 52.

[0030] Combination Figure 1 and Figure 2 The end face of the connecting plate 52 near the hinge seat 522 is machined into a protruding arc surface to facilitate the rotation of the rotating plate 53. The end face of the rotating plate 53 away from the hinge seat 522 has a through hole 531 connecting the two plate faces. Two threaded holes are spaced apart between the two connecting grooves 521 on the surface of the connecting plate 52. The positions of the threaded holes correspond to the positions of the through holes 531. When the rotating plate 53 fixes the reinforcing bars located in the connecting grooves 521, bolts are inserted into the through holes 531 and threaded into the threaded holes to fix the rotating plate 53, improving the efficiency of reinforcing bar installation. The through hole 531 is a countersunk hole.
