Description

Technical Field

[0001] This application relates to the field of floor structure technology, and in particular to a floor slab system for industrial plants. Background Technology

[0002] Currently, with the development of high-precision and automation levels in industry, more and more highly integrated robots, such as AGV transfer robots, are appearing in industrial plants. At the same time, the requirements for wear resistance, load-bearing capacity, stain resistance, and impermeability of flooring are also increasing. In order to meet the needs of heavy-duty fixed robots and handling robots in the floor slabs of industrial plants, load-bearing and wear-resistant floor slabs are gradually coming into view.

[0003] In related technologies, floor slabs are generally formed by pouring concrete onto a reinforcing mesh. However, since the reinforcing mesh is distributed in a two-dimensional plane, the area outside the plane containing the reinforcing mesh in the thickness direction of the floor slab is still plain concrete; therefore, the floor slab is prone to brittle cracking and damage under the impact of heavy external equipment. Utility Model Content

[0004] The purpose of this application is to provide an industrial plant floor slab system that addresses the problem of brittle cracking and damage in related technologies.

[0005] To achieve the above objectives, the technical solution adopted in the embodiments of this application is as follows:

[0006] This application provides an industrial plant floor slab, including a floor slab, a surface slab, and a cured surface. The surface slab includes a first concrete layer and a plurality of steel fiber structures disposed inside the first concrete layer. The first concrete layer is fixedly connected to the floor slab. The cured surface is formed on the side surface of the first concrete layer facing away from the floor slab.

[0007] The beneficial effects of the embodiments of this application are as follows: The industrial plant floor slab provided in the embodiments of this application forms a surface slab by pouring it on the floor slab and setting a cured surface on the surface slab, thereby forming a multi-layer floor; and the surface slab includes a first concrete layer and multiple steel fiber structures disposed inside the first concrete layer. The multiple steel fiber structures can be distributed in various parts of the first concrete layer and improve the tensile strength of the first concrete layer, thereby effectively improving the overall stability and load-bearing capacity of the first concrete layer and reducing the probability of brittle fracture damage to the first concrete layer.

[0008] In some embodiments, multiple steel fiber structures are evenly distributed within the first concrete layer.

[0009] By adopting the above technical solution, multiple steel fiber structures can further improve the overall tensile strength of the first concrete layer, further enhance the overall stability and load-bearing capacity of the first concrete layer, and effectively reduce the probability of partial brittle fracture damage of the first concrete layer.

[0010] In some embodiments, the floor slab includes a second concrete layer and a steel reinforcement structure disposed within the second concrete layer. In the thickness direction of the second concrete layer, at least two layers of steel reinforcement structures are sequentially distributed within the second concrete layer.

[0011] By adopting the above technical solution, by setting at least two layers of steel reinforcement structure in the second concrete layer along its own thickness direction, the at least two layers of steel reinforcement structure can more fully strengthen the second concrete layer in the thickness direction, thereby effectively improving the overall stability and load-bearing capacity of the floor slab.

[0012] In some embodiments, the first concrete layer has staggered first and second dividing joints on the side facing away from the floor slab, and the first and second dividing joints are filled with sealant.

[0013] By adopting the above technical solution, the first and second dividing joints are used to induce cracks in the first concrete layer, thereby reducing the probability of damage caused by random splitting and crack formation in the first concrete; at the same time, sealant is filled into the first and second dividing joints to reduce the probability of water seepage in the first and second dividing joints.

[0014] In some embodiments, the industrial plant floor slab also includes an anti-warping structural member, part of which is disposed within the floor slab and the other part of which is disposed within the first concrete layer.

[0015] By adopting the above technical solution, the anti-warping structural component can act on the first concrete layer to reduce the probability of the first concrete layer warping at the first and second dividing joints.

[0016] In some embodiments, there are multiple anti-warping structural members, wherein some anti-warping structural members are adjacent to the first dividing joint, and other anti-warping structural members are adjacent to the second dividing joint.

[0017] By adopting the above technical solution, anti-warping structural components are provided adjacent to the periphery of both the first and second dividing joints, thereby further reducing the probability of the first concrete layer warping at the first and second dividing joints.

[0018] In some embodiments, the anti-warping structural member includes a first connecting section and a second connecting section, the first connecting section being fixedly inserted into the floor slab, and the second connecting section being fixedly inserted into the first concrete layer; the second connecting section has a bent portion formed by bending towards the floor slab.

[0019] By adopting the above technical solution, the bending portion formed by the second connecting section bending towards the floor slab is used to abut against the first concrete layer, thereby effectively reducing the probability of the first concrete layer warping.

[0020] In some embodiments, the thickness of the first concrete layer is H, the depth of the first dividing joint is M, and the depth of the second dividing joint is N; wherein, 0 < M ≤ 1 / 3H, and / or, 0 < N ≤ 1 / 3H.

[0021] By adopting the above technical solution, the depth M of the first dividing joint and the depth N of the second dividing joint are limited to be greater than 0 and less than or equal to one-third of the thickness H of the first concrete layer, so that the first dividing joint and the second dividing joint can achieve the function of inducing cracking.

[0022] In some embodiments, a rough bonding surface is formed on the side of the floor slab facing the first concrete layer, and the first concrete layer is fixedly connected to the rough bonding surface.

[0023] By adopting the above technical solution, the bonding strength between the first concrete layer and the floor slab is improved by using a rough bonding surface, thereby reducing the probability of hollow cracks forming between the first concrete layer and the floor slab.

[0024] In some embodiments, an interface agent is provided on the rough bonding surface, and the rough bonding surface is fixedly connected to the surface layer plate through the interface agent.

[0025] By adopting the above technical solution, the bonding strength between the first concrete layer and the floor slab layer is further improved by using an interface agent, thereby further reducing the probability of hollow cracks forming between the first concrete layer and the floor slab layer.

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0039] In the description of this application, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0040] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0041] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0042] Currently, with the development of high-precision and automation levels in industry, more and more highly integrated robots, such as AGV transfer robots, are appearing in industrial plants. This also places increasingly higher demands on the wear resistance, load-bearing capacity, stain resistance, and impermeability of flooring. Furthermore, to meet the needs of heavy-duty fixed robots and handling robots within the floor slabs of industrial plants, load-bearing and wear-resistant floor slabs are gradually emerging. In related technologies, flooring is generally formed by pouring concrete into a steel mesh. However, because the steel mesh is distributed in a two-dimensional plane, the area outside the plane containing the steel mesh in the thickness direction of the floor is still plain concrete; therefore, the floor is prone to brittle cracking and damage under the impact of heavy external equipment.

[0043] Based on the above considerations, in order to solve the problem of brittle cracking damage in related floor slabs, an industrial plant floor slab was designed. The surface layer of the industrial plant floor slab includes a first concrete layer and multiple steel fiber structures. The multiple steel fiber structures are set inside the first concrete layer. Thus, the multiple steel fiber structures can be distributed at any point inside the first concrete layer and can enhance the tensile strength of the first concrete layer. Compared with the planar two-dimensional distribution of the steel mesh structure, the multiple steel fiber structures can be three-dimensionally distributed inside the first concrete layer, thereby effectively enhancing the overall stability and load-bearing capacity of the first concrete layer, and thus effectively reducing the probability of brittle cracking damage to the first concrete layer.

[0044] The following is a detailed description of the industrial plant floor slab provided in the embodiments of this application.

[0045] Please refer to Figure 1 and Figure 2This application provides an industrial plant floor slab 1000, including a floor slab 100, a surface slab 200, and a cured surface 300. The surface slab 200 includes a first concrete layer 210 and a plurality of steel fiber structures 220 disposed inside the first concrete layer 210. The first concrete layer 210 is fixedly connected to the floor slab 100. The cured surface 300 is formed on the side surface of the first concrete layer 210 facing away from the floor slab 100.

[0046] A floor slab 100 is a horizontal member in a building structure, primarily used to support the loads from above and transfer them to beams or columns. Floor slabs 100 are typically made of concrete, reinforced concrete, or other materials, and form the floor level and the supporting structure above it.

[0047] The surface panel 200 is a surface structure that covers the foundation structure in a building; in this embodiment, the surface panel 200 covers the floor slab 100.

[0048] The surface slab 200 includes a first concrete layer 210 and a plurality of steel fiber structures 220; wherein the first concrete layer 210 can be formed by casting concrete raw materials onto the floor slab 100. Exemplarily, in some embodiments, the concrete raw materials for the first concrete layer 210 can be low-shrinkage fine aggregate concrete.

[0049] Steel fiber structure 220 is a reinforcing material added to concrete to improve its performance. Steel fiber structure 220 can be, but is not limited to, steel wire, steel strip, steel block, etc. Steel fiber structure 220 can be added to the concrete raw materials forming the first concrete layer 210. After the concrete raw materials are poured to form the first concrete layer 210, the steel fiber structure 220 can fill and fix within the first concrete layer 210. Exemplarily, in some embodiments, the steel fiber structure 220 can be steel wire, and the steel wire can be distributed throughout the interior of the first concrete layer 210.

[0050] It should be understood that, compared to setting a steel mesh structure within the first concrete layer 210, the steel fiber structure 220 can be placed anywhere within the first concrete layer 210, for example, covering the entire first concrete layer 210. That is, the steel fiber structure 220 can be distributed three-dimensionally within the first concrete layer 210, rather than being distributed only two-dimensionally at any height within the first concrete layer 210 as the steel mesh structure. Therefore, the tensile strength of the first concrete layer 210 with the steel fiber structure 220 is effectively improved, thereby effectively hindering the propagation of micro-cracks and the formation of macro-cracks within the concrete, significantly improving the tensile, flexural, impact, and fatigue resistance of the concrete, and exhibiting good ductility. Simultaneously, by adding the steel fiber structure 220 to the concrete material forming the first concrete layer 210, and pouring and fixing it within the first concrete layer 210 along with the concrete material, the traditional steel mesh structure fabrication and subsequent reinforcement repositioning process can be eliminated, greatly improving the construction efficiency of the surface slab 200.

[0051] The cured surface 300 is formed on the surface of the first concrete layer 210 and is used for direct support contact and friction by transport equipment and machinery. It should be understood that the cured surface 300 should be configured to have high wear resistance and density. Exemplarily, in some embodiments, the cured surface 300 may be ground and polished using grinding and polishing equipment, and a curing agent may be applied to form a dense surface.

[0052] With this configuration, the industrial plant floor slab 100 and floor 1000 provided in this embodiment of the application can form a multi-layer floor by casting a surface slab 200 on the floor slab 100 and setting a cured surface 300 on the surface slab 200. Furthermore, the surface slab 200 includes a first concrete layer 210 and a plurality of steel fiber structures 220 disposed inside the first concrete layer 210. The plurality of steel fiber structures 220 can be distributed in various parts of the first concrete layer 210 and improve the tensile strength of the first concrete layer 210, thereby effectively improving the overall stability and load-bearing capacity of the first concrete layer 210 and reducing the probability of brittle fracture damage to the first concrete layer 210.

[0053] Please refer to Figure 1 and Figure 2 In some embodiments, multiple steel fiber structures 220 are evenly distributed within the first concrete layer 210.

[0054] Understandably, within the first concrete layer 210, multiple steel fiber structures 220 can be evenly distributed throughout the space; thus, the multiple steel fiber structures 220 can comprehensively enhance the tensile properties of the entire first concrete layer 210, thereby further improving the tensile properties, bending properties, impact properties, and fatigue properties of the entire surface plate 200.

[0055] The steel fiber structure 220 is used to be incorporated into the concrete raw materials that form the first concrete layer 210. Optionally, the steel fiber structure 220 can be added to the concrete raw materials using a shaking screen or a disperser, so that the multiple steel fiber structures 220 can be evenly dispersed. When the concrete raw materials are mixed and poured onto the floor slab 100, the steel fiber structure 220 can be evenly distributed throughout the first concrete layer 210 formed by pouring.

[0056] With this configuration, the multiple steel fiber structures 220 can further enhance the overall tensile strength of the first concrete layer 210, further improve the overall stability and load-bearing capacity of the first concrete layer 210, and effectively reduce the probability of brittle fracture damage to parts of the first concrete layer 210.

[0057] Please refer to Figure 1 and Figure 3 In some embodiments, the floor slab 100 includes a second concrete layer 110 and a steel reinforcement structure 120 disposed within the second concrete layer 110. In the thickness direction X of the second concrete layer 110, at least two layers of steel reinforcement structures 120 are sequentially distributed within the second concrete layer 110.

[0058] The second concrete layer 110 refers to the main structure of the floor slab 100 formed by pouring concrete raw materials.

[0059] The reinforcing steel structure 120 refers to a mesh structure composed of multiple reinforcing steel bars arranged in a crisscross pattern. The reinforcing steel structure 120 is used to fix the second concrete layer 110 inside to increase the strength and durability of the second concrete layer 110. For example, the multiple reinforcing steel bars can be distributed vertically and crosswise to form a mesh structure, and the intersecting reinforcing steel bars can be fixed together by binding, welding, or other methods; the reinforcing steel structure 120 can be fixed inside the second concrete layer 110 by pouring concrete into it.

[0060] The thickness direction X of the second concrete layer 110 refers to the direction parallel to the direction of gravity. At the same time, the thickness direction X of the second concrete layer 110 is also consistent with the distribution direction of the floor slab 100 and the surface slab 200.

[0061] Along the thickness direction X of the second concrete layer 110, at least two layers of reinforcing steel structures 120 are sequentially distributed within the second concrete layer 110. Optionally, two, three, or more layers of reinforcing steel structures 120 may be distributed along the thickness direction X of the second concrete layer 110. For example, in some embodiments, two layers of reinforcing steel structures 120 may be provided, and the two layers of reinforcing steel structures 120 may be fixed at different locations within the second concrete layer 110 at intervals along the thickness direction X. Thus, the two layers of reinforcing steel structures 120 can work together to strengthen the strength of the second concrete layer 110, and the two layers of reinforcing steel structures 120 reinforce the second concrete layer 110 at different parts of the second concrete layer 110, which can effectively improve the overall strength of the second concrete layer 110 and reduce the probability of brittle fracture damage to the second concrete layer 110.

[0062] With this configuration, by providing at least two layers of steel reinforcement 120 along its thickness direction X within the second concrete layer 110, the at least two layers of steel reinforcement 120 can provide more sufficient and comprehensive reinforcement to the second concrete layer 110 in the thickness direction X, thereby effectively improving the overall stability and load-bearing capacity of the floor slab 100.

[0063] Please refer to Figure 1 , Figure 2 , Figure 4 and Figure 5 In some embodiments, the first concrete layer 210 is provided with staggered first dividing joints 211 and second dividing joints 212 on the side opposite to the floor slab 100, and the first dividing joints 211 and second dividing joints 212 are filled with sealant 213.

[0064] The first dividing joint 211 serves as an inducing joint to induce cracking in the first concrete layer 210 along the first dividing joint 211, thereby reducing the probability of damage caused by random cracking of the first concrete layer 210. Optionally, the number of first dividing joints 211 can be any number of one, two, three, or more; when the number of first dividing joints 211 is two or more, the multiple first dividing joints 211 can be arranged parallel to each other and at intervals.

[0065] The second dividing joint 212 serves as an inducing joint to induce splitting of the first concrete layer 210 along the second dividing joint 212, thereby reducing the probability of damage caused by random cracking of the first concrete layer 210. Optionally, the number of second dividing joints 212 can be any number of one, two, three, or more; when the number of second dividing joints 212 is two or more, the multiple second dividing joints 212 can be arranged parallel to each other and at intervals.

[0066] Understandably, the first dividing joint 211 and the second dividing joint 212 formed by cutting can effectively control the shrinkage cracks generated in the first concrete layer 210 during the hardening process, so as to reduce the probability of the first concrete layer 210 being damaged due to random crack generation.

[0067] The first dividing joint 211 and the second dividing joint 212 are staggered, meaning they intersect, thus forming multiple grid structures. For example, when the first dividing joint 211 and the second dividing joint 212 are perpendicular, they form multiple rectangular grid structures; when they are not perpendicular, they form multiple rhomboid grid structures. By dividing the first concrete layer 210 into multiple smaller regions using the first dividing joint 211 and the second dividing joint 212, stress concentration can be reduced, improving the overall structural stability of the first concrete layer 210.

[0068] Meanwhile, joint sealant 213 is also filled in the first joint 211 and the second joint 212; for example, joint sealant 213 can be polyurethane adhesive, silicone adhesive, epoxy resin adhesive, acrylic adhesive, etc. By filling the first joint 211 and the second joint 212 with joint sealant 213, the probability of water seepage in the first joint 211 and the second joint 212 is effectively reduced. At the same time, joint sealant 213 can also increase the bonding strength of the first joint 211 and the second joint 212 to ensure the stability of the first concrete layer 210 under load; furthermore, joint sealant 213 can also absorb some of the movement and stress changes, reducing the propagation of cracks.

[0069] Please refer to Figure 1 as well as Figures 3 to 5 In some embodiments, the industrial plant floor slab 100 floor 1000 also includes an anti-warping structural member 400, part of which is disposed within the floor slab 100 and the other part of which is disposed within the first concrete layer 210.

[0070] Optionally, the anti-warping structural component 400 includes, but is not limited to, high-strength structural components such as reinforcing bars and steel strips. Part of the anti-warping structural component 400 is disposed within the floor slab 100, and another part of the anti-warping structural component 400 is disposed within the first concrete layer 210. Thus, through the connecting effect of the anti-warping structural component 400, the probability of the first concrete layer 210 warping relative to the floor slab 100 is reduced.

[0071] For example, in some embodiments, the anti-warping structural member 400 may be made of steel bars, one end of which may be embedded in the floor slab 100, for example, in the second concrete layer 110 of the floor slab 100, and the other end of which is exposed in the second concrete layer 110; during the process of pouring the second concrete layer 110 to form the first concrete layer 210, the steel bars exposed in the second concrete layer 110 are fixed inside the first concrete layer 210.

[0072] With this configuration, the anti-warping structural component 400 can act within the first concrete layer 210 to reduce the probability of the first concrete layer 210 warping at the first dividing joint 211 and the second dividing joint 212.

[0073] Please refer to Figures 3 to 5 In some embodiments, there are multiple anti-warping structural members 400, wherein some anti-warping structural members 400 are adjacent to the first dividing seam 211, and other anti-warping structural members 400 are adjacent to the second dividing seam 212.

[0074] The number of anti-warping structural components 400 can be multiple, such as two, three or more.

[0075] A portion of the anti-warping structural member 400 is disposed adjacent to the first dividing joint 211. Therefore, when the first concrete layer 210 is subjected to force on the periphery of the first dividing joint 211, the probability of the first concrete layer 210 warping on the periphery of the first dividing joint 211 is lower because the anti-warping structural member 400 acts on the portion of the first concrete layer 210 located on the periphery of the first dividing joint 211.

[0076] Similarly, another anti-warping structural member 400 is disposed adjacent to the second dividing joint 212. Therefore, when the first concrete layer 210 is subjected to force on the periphery of the second dividing joint 212, the probability of the first concrete layer 210 warping on the periphery of the second dividing joint 212 is lower because the anti-warping structural member 400 acts on the portion of the first concrete layer 210 located on the periphery of the second dividing joint 212.

[0077] With this configuration, anti-warping structural members 400 are provided adjacent to the periphery of both the first dividing joint 211 and the second dividing joint 212, which can further reduce the probability of the first concrete layer 210 warping at the first dividing joint 211 and the second dividing joint 212, thereby effectively improving the service life of the surface plate 200.

[0078] Please refer to Figures 3 to 5In some embodiments, the anti-warping structural member 400 includes a first connecting section 410 and a second connecting section 420. The first connecting section 410 is fixedly inserted into the floor slab 100, and the second connecting section 420 is fixedly inserted into the first concrete layer 210. The second connecting section 420 has a bend 421 formed by bending towards the floor slab 100.

[0079] The first connecting segment 410 and the second connecting segment 420 are two parts of the anti-warping structural member 400. For example, when the anti-warping structural member 400 is a steel bar, the first connecting segment 410 and the second connecting segment 420 are two sections of the steel bar along the length direction.

[0080] The second connecting segment 420 has a bend 421 formed by bending towards the floor slab 100. Optionally, a portion of the second connecting segment 420 can be bent at any angle to form the bend 421 described above. For example, in some embodiments, the end of the second connecting segment 420 facing away from the first connecting segment 410 can be bent at 180° towards the floor slab 100 to form a "U"-shaped bend 421. For example, when the anti-warping structural member 400 is a steel bar, the steel bar is bent to form a "J"-shaped structure. Thus, the end of the bend 421 faces the floor slab 100, and the end of the bend 421 can provide a supporting effect on the first concrete layer 210 to reduce the probability of the first concrete layer 210 warping.

[0081] With this configuration, the bend 421 formed by the second connecting section 420 bending towards the floor slab 100 serves to abut against the first concrete layer 210, thereby effectively reducing the probability of the first concrete layer 210 warping.

[0082] Please refer to Figures 3 to 5 In some embodiments, the thickness of the first concrete layer 210 is H, the depth of the first dividing joint 211 is M, and the depth of the second dividing joint 212 is N; wherein, 0 < M ≤ 1 / 3H, and / or, 0 < N ≤ 1 / 3H.

[0083] It should be understood that the first concrete layer 210 is a structure formed by pouring and covering the second concrete layer 110 on the floor slab 100. Therefore, the thickness direction of the first concrete layer 210 is consistent with the thickness direction X of the second concrete layer 110. The thickness H of the first concrete layer 210 refers to the distance between the two end surfaces in the thickness direction X of the first concrete layer 210 and the second concrete layer 110.

[0084] The depth M of the first dividing joint 211 refers to the distance between the surface of the first concrete layer 210 facing away from the second concrete layer 110 and the bottom end of the first dividing joint 211; the depth N of the second dividing joint 212 refers to the distance between the surface of the first concrete layer 210 facing away from the second concrete layer 110 and the bottom end of the second dividing joint 212.

[0085] The depth M of the first dividing joint 211 is limited to be greater than 0 and less than or equal to one-third of the thickness H of the first concrete layer 210. That is, the first dividing joint 211 splits into the first concrete layer 210 to form a crack structure, and the depth of the crack structure does not exceed one-third of the thickness H of the first concrete layer 210.

[0086] The depth N of the second dividing joint 212 is limited to be greater than 0 and less than or equal to one-third of the thickness H of the first concrete layer 210. That is, the second dividing joint 212 splits into the first concrete layer 210 to form a crack structure, and the depth of the crack structure does not exceed one-third of the thickness H of the first concrete layer 210.

[0087] This configuration limits the depth M of the first dividing joint 211 and the depth N of the second dividing joint 212 to be greater than 0 and less than or equal to one-third of the thickness H of the first concrete layer 210. This allows the first dividing joint 211 and the second dividing joint 212 to induce cracking, reducing the probability of damage caused by random cracks on the first concrete layer 210.

[0088] Please refer to Figures 1 to 3 In some embodiments, a rough bonding surface 101 is formed on the side surface of the floor slab 100 facing the first concrete layer 210, and the first concrete layer is fixedly connected to the rough bonding surface 101.

[0089] Understandably, rough bonding surface 101 refers to the surface structure of the floor slab 100 where the base layer is roughened by a milling machine to expose the coarse aggregate of concrete.
