Description

Technical Field

[0001] This application relates to the field of conductive concrete technology, and more particularly to a prestressed conductive concrete structure. Background Technology

[0002] The published patent with authorization announcement number CN211368263U discloses a prestressed conductive concrete structure, which relates to the field of concrete technology. The prestressed conductive concrete structure includes a corrugated mesh conductive heating mesh, which is wrapped with a rectangular block-shaped conductive concrete body. Prestressed steel bars are connected to both ends of the conductive heating mesh. The two prestressed steel bars extend vertically out of the conductive concrete body. The parts of the two prestressed steel bars outside the conductive concrete body are wrapped with insulating sleeves. Terminals are installed at the ends of the two prestressed steel bars. The terminals are electrically connected to wires through prestressed screws. This prestressed conductive concrete structure can maintain good electrothermal performance while ensuring sufficient compressive strength of the concrete, and it is not easy for the electrodes to separate from the concrete.

[0003] When the conductive concrete structure in the aforementioned patent is in use, the conductive heating mesh and the prestressed steel bars are connected by welding. Although no problems will occur in the early stages of use, under long-term harsh outdoor working conditions, the probability of the two detaching from the weld is relatively high. Once such a phenomenon occurs, it will require a lot of time and manpower for repair, thus increasing the operating cost and reducing the working efficiency, thereby reducing the practicality of the structure.

[0004] Therefore, this application proposes a prestressed conductive concrete structure. Utility Model Content

[0005] This application proposes a prestressed conductive concrete structure to solve the problems mentioned in the background art. This prestressed conductive concrete structure, by setting up a disassembly and assembly mechanism, connecting blocks, threaded grooves, prestressed steel bars, through holes and fixing bolts, can facilitate the disassembly and assembly of prestressed steel bars, avoid the problem of prestressed steel bars detaching after working inside the conductive concrete body for a long time, which is difficult to solve, reduce maintenance time, improve work efficiency, and greatly enhance the practicality of the structure.

[0006] To achieve the above objectives, this application adopts the following technical solution:

[0007] A prestressed conductive concrete structure includes a conductive concrete body with a placement groove inside. A conductive heating element is installed inside the placement groove. A disassembly and assembly mechanism is provided outside the conductive heating element. The disassembly and assembly mechanism includes a connecting block, which is fixedly connected to one side of the conductive heating element. A threaded groove is formed on one side surface of the connecting block. A prestressed steel bar is threadedly connected inside the threaded groove and extends through the outside of the threaded groove. Through holes are formed on the surfaces of the connecting block and the prestressed steel bar, and the through holes on the surfaces of the connecting block and the prestressed steel bar share a common center line. A fixing bolt is threadedly connected inside the through hole and extends through the through hole. An external spacer is wrapped around the connecting block and the prestressed steel bar. A terminal block is installed on one side of the external spacer, and an electric wire is installed on one side of the prestressed steel bar, extending through the outside of the terminal block.

[0008] In one preferred embodiment, a large amount of graphite material is added to the conductive concrete body during the manufacturing process;

[0009] By adding a large amount of graphite material to the conductive concrete body, it can be made to have electrical conductivity. When electricity is passed through it during operation, a large amount of heat is generated, which can melt the ice and snow on the road, thereby improving the practicality of the structure.

[0010] In a preferred embodiment, the placement groove is S-shaped;

[0011] By shaping the placement groove into an S-shape, the contact area between the conductive heating element and the placement groove can be increased, thereby enhancing the connection stability between the two. The increased contact area also facilitates rapid heat transfer, allowing the temperature of the conductive concrete body to rise more quickly, improving snow melting efficiency, and thus enhancing the practicality of the structure.

[0012] In a preferred embodiment, the conductive heating element, the connecting block, and the fixing bolts are all made of stainless steel.

[0013] By using stainless steel as the material for conductive heating elements, connecting blocks, and fixing bolts, the overall electrical conductivity of the structure can be guaranteed, ensuring that the structure can form a circuit with the external power source, allowing snow melting work to proceed normally, thereby improving the practicality of the structure.

[0014] In a preferred embodiment, the outer spacer is made of rubber and extends into the interior of the placement groove;

[0015] By using rubber as the material for the outer sleeve, it can serve as insulation, protecting the workers. Furthermore, by inserting one side of the outer sleeve into the placement groove, it can achieve a certain degree of sealing, isolating the inside of the placement groove from the outside world and protecting the internal structure, thereby improving the practicality of the structure.

[0016] In a preferred embodiment, a locking block is fixedly connected to one side of the terminal block, and the upper and lower locking blocks engage with each other;

[0017] By interlocking the upper and lower blocks, the wiring terminals can be fixed and are easy to disassemble, thus improving the practicality of the structure.

[0018] The beneficial effects of this application are:

[0019] 1. This prestressed conductive concrete structure, by setting up a disassembly and assembly mechanism, connecting blocks, threaded grooves, prestressed steel bars, through holes, and fixing bolts, facilitates the disassembly and assembly of prestressed steel bars. During installation, the prestressed steel bars are first screwed into the threaded grooves. When screwed to the innermost part, the fixing bolts are then screwed into the through holes. After passing through the through holes, the bolts are fixed with nuts to complete the installation of the prestressed steel bars. When disassembly and replacement are required, the operation is reversed. This mechanism avoids the problem of prestressed steel bars detaching from the weld after working inside the conductive concrete body for a long time, which is difficult to solve. It reduces maintenance time, improves work efficiency, and greatly enhances the practicality of the structure.

[0020] 2. This prestressed conductive concrete structure uses rubber as the material for the outer sleeve, which can serve as insulation and protect the workers. Furthermore, by inserting one side of the outer sleeve into the placement groove, it can achieve a certain degree of sealing, isolating the inside of the placement groove from the outside world and protecting the internal structure, thus greatly improving the practicality of the structure.

[0027] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0028] Reference Figure 1-3 A prestressed conductive concrete structure includes a conductive concrete body 1, in which a large amount of graphite material is added during the manufacturing process. By adding a large amount of graphite material to the conductive concrete body 1, it can be made conductive. When electricity is applied during operation, a large amount of heat is generated to melt the ice and snow on the road, thereby improving the practicality of the structure.

[0029] Reference Figure 1-2 The conductive concrete body 1 has a placement groove 2 inside, and a conductive heating element 3 is installed inside the placement groove 2. The placement groove 2 is S-shaped. By making the placement groove 2 S-shaped, the contact area between the conductive heating element 3 and the placement groove 2 can be increased, thereby enhancing the connection stability between the two. The increased contact area can help the heat transfer quickly, so that the temperature of the conductive concrete body 1 rises more quickly, improving the snow melting efficiency and thus enhancing the practicality of the structure.

[0030] Reference Figure 1-5 The conductive heating element 3 is provided with a disassembly and assembly mechanism 4. The disassembly and assembly mechanism 4 includes a connecting block 41, and the connecting block 41 is fixedly connected to one side of the conductive heating element 3. A threaded groove 42 is opened on one side surface of the connecting block 41. A prestressed steel bar 43 is threadedly connected inside the threaded groove 42, and the prestressed steel bar 43 passes through to the outside of the threaded groove 42. A through hole 44 is opened on the surface of the connecting block 41 and the prestressed steel bar 43, and the through hole 44 passes through the connecting block 41. The through hole 44 opened on the surface of the connecting block 41 and the prestressed steel bar 43 share a common center line. A fixing bolt 45 is threadedly connected inside the through hole 44, and the fixing bolt 45 passes through the through hole 44.

[0031] During installation, the prestressed steel bar 43 is first screwed into the threaded groove 42. When it is screwed to the innermost part, the fixing bolt 45 is then screwed into the through hole 44. After passing through the through hole 44, it is fixed with a nut to complete the installation of the prestressed steel bar 43. When disassembly and replacement are required, the operation is reversed. This mechanism avoids the problem of the prestressed steel bar 43 detaching from the weld after working inside the conductive concrete body 1 for a long time, which is difficult to solve. It reduces maintenance time, improves work efficiency, and thus enhances the practicality of the structure.

[0032] Reference Figure 1-4 The conductive heating element 3, the connecting block 41, and the fixing bolt 45 are all made of stainless steel. By using stainless steel as the material for the conductive heating element 3, the connecting block 41, and the fixing bolt 45, the overall electrical performance of the structure can be guaranteed, and the structure can form a circuit with the external power source, so that the snow melting work can be carried out normally, thereby improving the practicality of the structure.

[0033] Reference Figure 3 , 5 The connecting block 41 and the prestressed steel bar 43 are wrapped with an outer spacer 5. The outer spacer 5 is made of rubber and extends into the interior of the placement groove 2. By using rubber as the material of the outer spacer 5, it can play an insulating role and protect the workers. Furthermore, by inserting one side of the outer spacer 5 into the interior of the placement groove 2, it can play a certain sealing role, isolating the interior of the placement groove 2 from the outside world and protecting the internal structure, thereby improving the practicality of the structure.

[0034] Reference Figure 3 , 5 A terminal block 6 is installed on one side of the outer sleeve 5, and a wire 7 is installed on one side of the prestressed steel bar 43. The wire 7 passes through to the outside of the terminal block 6. A locking block 61 is fixedly connected to one side of the terminal block 6, and the upper and lower locking blocks 61 engage with each other. By engaging the upper and lower locking blocks 61 with each other, the terminal block 6 can be fixed and is easy to disassemble, thereby improving the practicality of the structure.

[0035] Working principle: During installation, the prestressed steel bar 43 is first screwed into the threaded groove 42 until it reaches the innermost position. Then, the fixing bolt 45 is screwed into the through hole 44, and after passing through the through hole 44, it is secured with a nut, completing the installation of the prestressed steel bar 43. The upper and lower locking blocks 61 are then engaged to fix the terminal 6 and connect the wire 7 to the prestressed steel bar 43. Electricity is then supplied through the wire 7 to heat and melt snow. By adding a large amount of graphite material to the conductive concrete body 1, it can be made conductive. When energized, it generates a large amount of heat. The S-shaped shape of the placement groove 2 increases the contact area between the conductive heating element 3 and the placement groove 2, thereby enhancing the connection stability between the two. The increased contact area also helps to generate heat. Rapid heat transfer allows the temperature of the conductive concrete body 1 to rise more quickly, improving snow melting efficiency. Using stainless steel as the material for the conductive heating element 3, connecting block 41, and fixing bolt 45 ensures the overall electrical conductivity of the structure and guarantees that the structure can form a circuit with the external power source, allowing the snow melting work to proceed normally. Using rubber as the material for the outer partition 5 provides insulation and protection for workers. Inserting one side of the outer partition 5 into the placement groove 2 provides a certain degree of sealing, isolating the interior of the placement groove 2 from the outside and protecting the internal structure. When it is necessary to disassemble and replace the prestressed steel bar 43, the operation is reversed. This mechanism avoids the problem of the prestressed steel bar 43 detaching after working inside the conductive concrete body 1 for a long time, which is difficult to solve.

[0036] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and the inventive concept of this application, should be included within the scope of protection of this application.
