Description

Technical Field

[0001] The invention relates to a reinforced concrete wall structure. Background Art

[0002] Reinforced concrete components are composed of steel bars and concrete. Steel bars possess strong tensile and compressive properties within the structure, while concrete has only high compressive strength and very low tensile strength. The concrete covering from the outer edge of the steel bars to the surface of the structural member forms a protective concrete layer for the steel. The combination of the two creates a strong bond and allows them to leverage their respective load-bearing properties, jointly bearing the external loads required of the structural member. The concrete cover protects the steel bars within reinforced concrete components. The concrete cover has excellent sealing properties, and the aggregate, cement, and other materials that make up the concrete block out air and moisture, preventing corrosive substances from contacting the internal steel bars and causing rust, thereby extending the service life of the steel bars. The bonding between the concrete cover and the steel bars ensures that the steel bars do not separate from the concrete when subjected to stress, giving the building structure greater integrity and stability.

[0003] In the current construction process, there are high requirements for the construction of concrete protective layer. If the construction process is improper, cracks are likely to occur, affecting the compressive performance of reinforced concrete components. Improper construction of the concrete protective layer is also likely to cause water leakage and seepage in the protective layer, which cannot block air and moisture, causing internal steel bars to rust, which will affect the overall stability of the building. Summary of the Invention

[0004] In response to the shortcomings of the existing technology, the purpose of the present invention is to provide a reinforced concrete wall structure, in which the thickness of the concrete protective layer is controlled by setting a thickness control member, and a structure for fixing the FRP mesh is provided, so that the combination of the FRP mesh and the concrete is more stable, which better protects the internal steel bars and thus makes the structure have better integrity and stability; a layer of FRP mesh can be laid on the periphery of the concrete protective layer and a multi-layer structure of spraying penetrating crystalline coating can be further improved, which can further improve the performance of the wall, such as impermeability and crack resistance.

A pushing plate is provided at the position of the rotating rod in the recess. One end of the rotating rod is rotatably connected to the inner wall of the recess, and the other end passes through the concave vertical rod and is configured with a gear. The gears on the same concave vertical rod are jointly configured with a rack, and the rack is meshed with the gear. The gear rotates the rotating rod by the up and down movement of the rack. The rotating rod rotates the pushing plate to swing synchronously and thereby push the extension rod to extend.

DETAILED DESCRIPTION

[0029] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the invention, the specific implementation methods, structures, features and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0030] Refer to Figures 1-10 As shown, the present application provides a reinforced concrete wall structure, including a skeleton 1 within an external formwork system 17. The external formwork system 17 uses external supports to provide abutment force to the formwork, and does not use a tension screw formwork system. The external formwork system 17 is a prior art and will not be described in detail here. The skeleton 1 is provided with at least one set of thickness control members 2. The number of thickness control members 2 is set according to the length of the wall. The thickness control members 2 are used to control the thickness of the concrete protective layer. The end face of the thickness control member 2 away from the skeleton 1 forms a clamping and abutting surface. The clamping and abutting surface is provided with a clamping member 3. The clamping member 3 is used to fix a first FRP mesh 4. The first FRP mesh 4 is confined between the inner surface of the external formwork system 17 and the clamping member 3. Concrete is poured in the external formwork system 17. The first FRP mesh 4 and the concrete on the outer end face are interlocked to form a concrete protective layer.

[0031] like Figure 4As shown, the thickness control member 2 includes two longitudinal adjustment sections 5 and multiple sets of vertically distributed transverse hinges 6 connecting the two sets of longitudinal adjustment sections 5. A connecting plate 8 is provided between each of the upper and lower adjacent transverse hinges 6. Both the connecting plates 8 and the end faces of the longitudinal adjustment sections 5 facing the frame 1 are provided with clamps 9. The clamps 9 are adjustable vertically to facilitate installation with the frame 1. The longitudinal adjustment sections 5 and the connecting plates 8 are secured to the frame 1 via the clamps 9. The clamps 9 are conventional and will not be described in detail here. The attachment of the connecting plates 8 and the longitudinal adjustment sections 5 shapes the hinge angle of the transverse hinges 6 and allows the hinged ends to abut against the frame 1. Each hinged end of the transverse hinge 6 is provided with a first longitudinal telescopic end 7. The combination of the first longitudinal telescopic end 7 and the transverse hinge 6 forms a bidirectional abutment surface. The provision of the transverse hinges 6 reduces the space occupied during transportation of the thickness control member 2, thereby increasing the number of units that can be transported, and provides a certain abutment force when securing the first FRP mesh 4. Specifically, the transverse hinged portion 6 includes a first hinged rod 61, a second hinged rod 62, a third hinged rod 63 and a fourth hinged rod 64. One end of the first hinged rod 61 and the fourth hinged rod 64 are hinged to the similar concave vertical rod 51, the other end of the first hinged rod 61 is hinged to one end of the second hinged rod 62, and the other end of the fourth hinged rod 64 is hinged to one end of the third hinged rod 63. The other ends of the second hinged rod 62 and the third hinged rod 63 are both hinged to the connecting block. The upper and lower ends of the connecting plate 8 are connected to the upper and lower connecting blocks. The first longitudinal telescopic end 7 is distributed at the common hinged end of the first and second hinged rods and the common hinged end of the third and fourth hinged rods. As shown in the figure, the first longitudinal telescopic end 7 includes an abutment plate 10 connected to the upper and lower ends of the common hinged end roller shaft. The abutment plate 10 is provided with a sliding cavity for the sliding rod 11 to slide. The extension length of the sliding rod 11 is adjusted between the sliding rod 11 and the abutment plate 10 by a positioning pin, and the extension length of the sliding rod 11 can also be achieved through a threaded connection, thereby forming the corresponding thickness of the concrete protective layer.

[0032] like Figure 4-Figure 7As shown, the longitudinal adjustment portion 5 includes a concave vertical rod 51 and an extension rod 52 arranged in the recess of the concave vertical rod 51. The extension rod 52 is slidably connected to the inner wall of the recess by a telescopic spring. A pushing portion 54 is provided between the extension rod 52 and the concave vertical rod 51. The pushing portion 54 is used to push the extension rod 52 to adjust the overall longitudinal length and thereby obtain the required concrete protective layer thickness. As shown in the figure, the pushing portion 54 includes a plurality of groups of vertically distributed rotating rods 541 that pass through the recess of the concave vertical rod 51 laterally. A pushing plate 544 is provided at the position where the rotating rod 541 is located in the recess. One end of the rotating rod 541 is rotatably connected to the inner wall of the recess, and the other end passes through the concave vertical rod 51 and is provided with a gear 542. The gear 542 on the same concave vertical rod 51 is jointly provided with a rack. 543, the rack 543 is connected to the side wall of the concave vertical rod 51 for sliding movement. The concave vertical rod 51 is also provided with multiple positioning holes in the vertical direction. The rack 543 is provided with positioning pins corresponding to the positioning holes. According to the required extension length of the extension rod 52, the rack 543 pushes upward, the rotating rod 541 rotates, and then drives the push plate 544 to swing toward the extension rod 52, which will generate a driving force on the extension rod 52, causing the extension rod 52 to move along the sliding direction of the telescopic spring. When the extension rod 52 has moved the required length, the positioning pins on the rack 543 are inserted into the corresponding positioning holes to fix the position of the rack 543, synchronously limiting the rotation of the rotating rod 541 caused by the gear 542, thereby determining the extension length of the extension rod 52 and the longitudinal length of the concave vertical rod 51, which together form the thickness of the concrete protective layer. The configuration of the pusher 54 is not limited to the above configuration, and any configuration that can achieve the extension of the extension rod 52 is applicable. However, the above-mentioned pusher 54 is the preferred embodiment of the present application. By fixing the positions of the longitudinal adjustment portion 5 and the connecting plate 8 and longitudinally adjusting the longitudinal adjustment portion 5 and the first longitudinal telescopic end 7, the thickness control member 2 is fixed to the skeleton 1 and the thickness of the concrete cover is determined. The thickness control of the thickness control member 2 can be performed synchronously by another group of workers during the process of erecting the skeleton 1. In this way, after the skeleton 1 is set up, the thickness control member 2 is adjusted and directly installed on the skeleton 1 through the clamp 9, and then the first FRP mesh 4 is fixed.

[0033] like Figure 6As shown, the first FRP mesh 4 is fixed by a clamp 3, and a plurality of sockets 12 are provided at the end of a sliding rod 11. The plurality of sockets 12 are equipped with detachable plugs 13. The first FRP mesh 4 can be fixed in a limited position by the cooperation between the plugs and the sockets 12, or the first FRP mesh 4 can be fixed to the sliding rod 11 by nails to ensure the flatness of the first FRP mesh 4. The clamping member 3 is distributed at the clamping mouth 53 of the extension rod 52. The clamping member 3 includes a fixed serrated protrusion 31 extending upward from the lower end surface of the clamping mouth 53. The upper end of the clamping mouth 53 is provided with a movable serrated protrusion 32 that moves up and down corresponding to the fixed serrated protrusion 31. The movable serrated protrusion 32 is engaged with the fixed serrated protrusion 31 and the contact end surfaces of the serrated protrusions are staggered with small protrusions. The movable serrated protrusion 32 is arranged in a cavity at the upper end of the clamping mouth 53 and is equipped with a driving part 33. The movable serrated protrusion 32 is driven up and down by the driving part 33. As shown in the figure, the driving part 33 includes a rack 543 groove on the movable serrated protrusion 32, and the rack 543 groove is engaged with a gear 542 rotating rod 541. One end of the gear 542 rotating rod 541 passes through the extension rod 52 and is provided with a stop-rotation movable block. The movable serrated protrusion 32 is moved up and down by rotating the gear 542 rotating rod 541. Alternatively, the movable serrated protrusion 32 can be driven up and down by engaging the screw rod with the bevel gear 542; or the movable serrated protrusion 32 can be pushed up and down to move up and down, and then the position of the movable serrated protrusion 32 can be fixed by a positioning pin. The above methods of moving the movable serrated protrusion 32 up and down are all existing technologies and will not be described in detail here. Since the first FRP mesh 4 is fixed by the fixed serrated protrusion 31 and the movable serrated protrusion 32, the first FRP mesh 4 will be folded in half. Therefore, the present application also improves the first FRP mesh 4, thereby making it fit more closely with the thickness control member 2, such as Figure 8 As shown, an extended grid is fixed to the clamping position for the clamping member 3 to clamp; or as Figure 9 As shown, the first FRP mesh 4 is cut to form a rectangular opening, and then the upper and lower ends of the rectangular opening are aligned and bonded together through bonding or wire tying, so that the first FRP mesh 4 corresponds to the position of the clamping member 3 to form a double-sided opening, which is then clamped by the clamping member 3. Both of the above methods ensure that the first FRP mesh 4 remains flat and stably fixed to the thickness control member 2 when fixed to the thickness control member 2, and is not easily dislodged. Then, an external formwork system 17 is erected on the periphery, and concrete is poured within the external formwork system 17. After the concrete is formed, the formwork is removed.

[0034] like Figure 1As shown, to further enhance the performance of the concrete cover, a permeable crystallization coating 14 is sprayed onto the periphery. This permeable crystallization coating 14 comprises active silicon, cement, and an active inorganic mixture. This self-repairing waterproof coating, developed through high-tech methods using active silicon, cement, and an active inorganic mixture, possesses excellent adhesion and integrates seamlessly with the concrete cover. It also reinforces the mesh and forms a single unit with the concrete. Its key feature is that after bonding with the concrete, it penetrates into the concrete cover and forms water-insoluble permeable crystals. These permeable crystals fill cracks in the concrete structure, making it denser and thus improving the waterproof and anti-seepage properties of the concrete cover. This permeable crystallization coating 14 is resistant to aging, enhances the durability of concrete, and slows down its carbonation process. A second FRP mesh 15 can also be laid between the permeable crystallization coating 14 and the concrete cover to form a multilayer structure, further enhancing the anti-seepage and anti-cracking properties of the concrete cover.

[0035] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as above in terms of a preferred embodiment, it is not intended to limit the present invention. Any person skilled in the art can, without departing from the scope of the technical solution of the present invention, make some changes or modifications to equivalent embodiments using the technical contents disclosed above. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
