Abstract
Description
Technical Field
[0001] This utility model relates to the field of steel structure auxiliary components, specifically to a corrosion protection structure for steel structure welds. Background Technology
[0002] In civil engineering, the connection of steel structural components is a crucial aspect. Common connection methods, such as steel pipe piles and I-beams, typically employ on-site welding. However, this method presents a significant problem: the steel at the weld seam and in the vicinity is exposed to the high temperatures of the welding flame, causing damage to the applied anti-corrosion coating. The primary function of the anti-corrosion coating is to protect the steel from corrosive gases and water. Once the coating is damaged, the steel structure is exposed to a corrosive environment, becoming a weak point and significantly shortening its service life.
[0003] In existing technologies, the common approach to corrosion protection of welds and surrounding areas is to reapply anti-corrosion material after welding. However, in practice, this method has several drawbacks. First, the process of reapplying the anti-corrosion material is cumbersome, and it is difficult to ensure that the quality of the coating is consistent with the original coating. Second, even if the anti-corrosion material is reapplied, the anti-corrosion effect will be significantly reduced because the microstructure of the steel may change during the welding process. Utility Model Content
[0004] The purpose of this utility model is to provide a corrosion protection structure for steel structure welds in order to solve the above problems, as detailed below.
[0005] To achieve the above objectives, the present invention provides the following technical solution: This utility model provides a corrosion protection structure for steel structure welds, including a steel structure base and a steel structure column. The steel structure base is horizontally arranged, and the steel structure column is vertically welded and fixed to the top of the steel structure base. The periphery where the steel structure column and the steel structure base meet is the weld. A corrosion-resistant inner lining is wrapped around the weld between the steel structure column and the steel structure base, and a waterproof outer lining is wrapped around the outside of the corrosion-resistant inner lining. This is to achieve stable corrosion protection and waterproof protection for the weld by adding the corrosion-resistant inner lining and the waterproof outer lining around the weld. The top outer periphery of the anti-corrosion liner and the waterproof liner is provided with a circumferential clamping component, and the top outer periphery of the anti-corrosion liner and the waterproof liner is tightened and constrained by the circumferential clamping component to prevent loosening and water seepage after the top outer periphery of the anti-corrosion liner and the waterproof liner is tightened and constrained. The front and rear positions of the circumferential compression assembly are combined with a downward pressing component, and the bottom of the anti-corrosion liner and the waterproof outer liner are tightly pressed and constrained from top to bottom by the downward pressing component to prevent loosening and water leakage after the bottom of the anti-corrosion liner and the waterproof outer liner are pressed and tightened.
[0006] Preferably, the anti-corrosion lining is epoxy resin impregnated carbon fiber cloth, and the waterproof outer lining is a rubber bushing.
[0007] Preferably, both the anti-corrosion inner lining and the waterproof outer lining are wound for a length greater than one full turn.
[0008] Preferably, the top edge of the waterproof outer liner is higher than the top edge of the anti-corrosion inner liner, and the lower edge of the waterproof outer liner extends beyond the lower edge of the anti-corrosion inner liner.
[0009] Preferably, the circumferential clamping assembly includes rectangular clamps and bolted connectors. There are two rectangular clamps, which are aligned front to back and fit together on the top outer periphery of the anti-corrosion inner lining and the waterproof outer lining. The downward pressing and tightening assembly is assembled at both the front and rear positions of the rectangular clamps. Connecting winglets are extended and fixedly connected to both sides of the rectangular clamps, and the front and rear connecting winglets are fixed together by inserting the bolted connectors.
[0010] Preferably, the top of the rectangular clamp is higher than the top edge of the waterproof outer liner, and the bottom of the rectangular clamp is lower than the top edge of the anti-corrosion inner liner.
[0011] Preferably, each of the pressing and clamping components includes a mounting plate, a clamping stud, and a pressure plate. The outer end faces of the rectangular clamping members at the front and rear positions, which are far apart from each other, are all fixed with the mounting plate. Each mounting plate has several guide holes vertically. The clamping stud is inserted through each guide hole in a vertical sliding fit. The bottom end of the clamping stud at the front position is fixed with the pressure plate, and the bottom end of the clamping stud at the rear position is also fixed with the pressure plate. At the same time, the pressure plates at the front and rear positions are aligned and closed. The portion of the clamping stud between the bottom surface of the mounting plate and the top surface of the pressure plate is coaxially engaged with several locking nuts.
[0012] Preferably, the top of each clamping stud is coaxially and detachably fitted with an anti-detachment cap with an outer diameter larger than that of the guide hole. The mounting plate and the rectangular clamp are both fixedly connected with reinforcing ribs at their joint positions, and the reinforcing ribs do not interfere with each other with the locking nut.
[0013] Preferably, all the pressure plates are U-shaped plates, and the pressure plates at the front and rear positions are closed to form a complete rectangular frame. At the same time, the outer edge of the pressure plate extends beyond the lower edge of the waterproof lining, and the inner edge of the pressure plate does not extend beyond the outer edge of the anti-corrosion lining.
[0014] Preferably, the outer periphery of the clamping stud is all Tang thread, and the number of locking nuts of the clamping stud is two and the rotation direction is opposite.
[0015] In the above-mentioned anti-corrosion protection structure for steel structure welds, specifically, because the anti-corrosion inner lining is wrapped around the weld between the steel structure column and the steel structure base, and the anti-corrosion inner lining is covered by a waterproof outer lining, and the top periphery of the anti-corrosion inner lining and the waterproof outer lining are tightened and constrained by the circumferential clamping component, and the bottom of the anti-corrosion inner lining and the waterproof outer lining are tightly constrained from top to bottom by the downward pressing and tightening component, stable anti-corrosion and waterproof protection of the weld can be achieved by adding the anti-corrosion inner lining and the waterproof outer lining around the weld, which helps to ensure the stability and reliability of the weld position. Furthermore, because the anti-corrosion inner lining is... The epoxy resin impregnated carbon fiber cloth provides the anti-corrosion lining with excellent and stable adhesion and corrosion resistance, ensuring that it adheres tightly to the exterior of the steel structure column and base, covering the welds for corrosion protection. Simultaneously, the waterproof outer lining, being a rubber bushing, provides excellent and stable water-proof capability, ensuring it effectively isolates and protects the anti-corrosion lining and welds, thus extending its service life. Furthermore, the rectangular clamps of the circumferential clamping assembly, combined with the connecting flaps on both sides, provide additional protection. The bolted connection method allows for stable tightening and restraint of the top outer periphery of the anti-corrosion liner and the waterproof liner. Furthermore, the tightening and restraint of the top outer periphery of the anti-corrosion liner and the waterproof liner can be released simply by sequentially removing the bolted connection and the rectangular clamp. This method of tightening and releasing the top outer periphery of the anti-corrosion liner and the waterproof liner is simple and easy to implement. It facilitates preventing loosening and water leakage after tightening the top outer periphery of the anti-corrosion liner and the waterproof liner, and also facilitates subsequent maintenance and replacement after loosening the top outer periphery of the anti-corrosion liner and the waterproof liner. Additionally, the lower clamp is combined at both the front and rear positions of the circumferential clamping assembly. The pressure-tightening assembly, by tightening the locking nuts of the pressure-tightening assembly onto the bottom surface of the mounting plate, allows the pressure plate to tightly restrain the bottom of the anti-corrosion liner and the waterproof outer liner from top to bottom. Simultaneously, simply unscrewing the locking nuts away from the bottom surface of the mounting plate releases the pressure plate's downward pressure on the anti-corrosion liner and the waterproof outer liner. This downward pressure-tightening method is simple and easy to implement, facilitating both the tightening of the bottom of the anti-corrosion liner and the waterproof outer liner to prevent loosening and water leakage, and also facilitating subsequent loosening of the bottom of the anti-corrosion liner and the waterproof outer liner for maintenance and replacement.
[0016] The beneficial effects are as follows: 1. This utility model has an anti-corrosion inner lining wrapped around the weld between the steel structure column and the steel structure base, and a waterproof outer lining wrapped around the outside of the anti-corrosion inner lining. The top periphery of the anti-corrosion inner lining and the waterproof outer lining are tightened and constrained by the circumferential compression component, and the bottom of the anti-corrosion inner lining and the waterproof outer lining are tightly constrained from top to bottom by the downward pressing component. In this way, by adding an anti-corrosion inner lining and a waterproof outer lining around the weld, stable anti-corrosion and waterproof protection of the weld can be achieved, which is conducive to ensuring the stability and reliability of the weld position. 2. The anti-corrosion lining is made of carbon fiber cloth impregnated with epoxy resin, which gives the anti-corrosion lining good and stable adhesion and corrosion resistance. This ensures that the anti-corrosion lining can adhere tightly to the outside of the steel structure column and steel structure base and cover the weld for anti-corrosion protection. The waterproof lining is made of rubber bushing, which gives the waterproof lining good and stable water-proof ability. This ensures that the waterproof lining can isolate and protect the anti-corrosion lining and weld, which helps to improve the service life of the anti-corrosion lining. 3. By using the rectangular clamps of the circumferential clamping assembly to close and by inserting bolts into the connecting winglets on both sides, the top outer periphery of the anti-corrosion lining and the waterproof lining can be stably tightened and constrained. At the same time, the tightening and constraining of the top outer periphery of the anti-corrosion lining and the waterproof lining can be released by simply removing the bolts and the rectangular clamps in sequence. The tightening and releasing of the top outer periphery of the anti-corrosion lining and the waterproof lining is simple and easy to implement. It is convenient to tighten the top outer periphery of the anti-corrosion lining and the waterproof lining to prevent loosening and water leakage, and it is also convenient to loosen the top outer periphery of the anti-corrosion lining and the waterproof lining for maintenance and replacement in the future. 4. The front and rear positions of the circumferential clamping assembly are both equipped with downward pressing and tightening components. By tightening the locking nuts of the downward pressing and tightening components onto the bottom surface of the mounting plate, the pressure plate can tightly restrain the bottom of the anti-corrosion lining and the waterproof outer lining from top to bottom. At the same time, simply unscrewing the locking nuts away from the bottom surface of the mounting plate can release the downward pressing and tightening state of the pressure plate on the bottom of the anti-corrosion lining and the waterproof outer lining. The downward pressing and tightening method of the anti-corrosion lining and the waterproof outer lining is simple and easy to implement. It is convenient to press and tighten the bottom of the anti-corrosion lining and the waterproof outer lining to prevent loosening and water leakage. It is also convenient to loosen the bottom of the anti-corrosion lining and the waterproof outer lining for maintenance and replacement later. Attached Figure Description

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0021] See Figures 1-7 As shown, this utility model provides a corrosion protection structure for steel structure welds, including a steel structure base 3 and a steel structure column 1. The steel structure base 3 is horizontally arranged, and the steel structure column 1 is vertically welded and fixed to the top of the steel structure base 3. The perimeter of the joint between the steel structure column 1 and the steel structure base 3 is the weld 7. The perimeter of the weld 7 between the steel structure column 1 and the steel structure base 3 is wrapped with an anti-corrosion inner lining 6, and the outside of the anti-corrosion inner lining 6 is covered with a waterproof outer lining 5. The advantage of this arrangement is that by adding an anti-corrosion inner lining 6 and a waterproof outer lining 5 around the weld 7, stable corrosion protection and waterproof protection of the weld 7 can be achieved.
[0022] See Figures 1-4 As shown, a circumferential clamping assembly 2 is provided on the top outer periphery of the anti-corrosion inner liner 6 and the waterproof outer liner 5. The top outer periphery of the anti-corrosion inner liner 6 and the waterproof outer liner 5 is tightened and constrained by the circumferential clamping assembly 2 to prevent loosening and water leakage after tightening and constraining the top outer periphery of the anti-corrosion inner liner 6 and the waterproof outer liner 5. Specifically, the circumferential clamping assembly 2 includes a rectangular clamp 203 and a bolt connector 201. There are two rectangular clamps 203, which are aligned front to back and fit together on the top outer periphery of the anti-corrosion inner liner 6 and the waterproof outer liner 5. A downward pressing and tightening assembly 4 is provided at both the front and rear positions of the rectangular clamp 203. Connecting winglets 202 are extended and fixedly connected to both sides of the rectangular clamp 203. Furthermore, the connecting wing pieces 202 at the front and rear are all fixed together by inserting bolts 201. The purpose of this arrangement is to securely tighten the top outer periphery of the anti-corrosion lining 6 and the waterproof lining 5 by closing the rectangular clamp 203 around the clamping component 2 and inserting bolts 201 on the connecting wing pieces 202 at both sides. At the same time, the tightening constraint on the top outer periphery of the anti-corrosion lining 6 and the waterproof lining 5 can be released by simply removing the bolts 201 and the rectangular clamp 203 in sequence. The tightening and releasing of the top outer periphery of the anti-corrosion lining 6 and the waterproof lining 5 is simple and easy to implement.
[0023] See Figures 1-7 As shown, the front and rear positions of the circumferential clamping assembly 2 are combined with a downward pressing and tightening assembly 4, and the bottoms of the anti-corrosion inner liner 6 and the waterproof outer liner 5 are tightly pressed and constrained from top to bottom by the downward pressing and tightening assembly 4, so as to prevent loosening and water leakage after the bottoms of the anti-corrosion inner liner 6 and the waterproof outer liner 5 are pressed and tightened. Specifically, the downward pressing and tightening assembly 4 includes a mounting plate 401, a clamping stud 404 and a pressure plate 402. The outer end faces of the rectangular clamping members 203 at the front and rear positions are all flatly extended and fixed with the mounting plate 401, and the mounting plate 401 is vertically provided with a number of guide holes 406. The guide holes 406 are all vertically slidingly fitted with the clamping stud 404, and the bottom end of the clamping stud 404 at the front position is flatly fixed with the pressure plate 402, and the bottom end of the clamping stud 404 at the rear position is flatly fixed with the pressure plate 402. The bottom end of the clamping stud 404 is also fixed with a pressure plate 402. At the same time, the pressure plates 402 at the front and rear positions are aligned and closed. Several locking nuts 403 are coaxially engaged between the bottom surface of the mounting plate 401 and the top surface of the pressure plate 402 on the part of the clamping stud 404. The purpose of this arrangement is that by tightening the locking nuts 403 of the downward pressing and clamping component 4 onto the bottom surface of the mounting plate 401, the pressure plate 402 can tightly press and constrain the bottom of the anti-corrosion lining 6 and the waterproof outer lining 5 from top to bottom. At the same time, the downward pressing and clamping state of the pressure plate 402 on the bottom of the anti-corrosion lining 6 and the waterproof outer lining 5 can be released by simply unscrewing the locking nuts 403 away from the bottom surface of the mounting plate 401. The downward pressing and clamping method on the bottom of the anti-corrosion lining 6 and the waterproof outer lining 5 is simple and easy to implement.
[0024] See Figures 1-7 As shown, the following optimizations have been made to this application. Specifically, the anti-corrosion liner 6 is made of epoxy resin impregnated carbon fiber cloth, and the waterproof liner 5 is made of rubber bushing. This configuration firstly ensures that the anti-corrosion liner 6 has good and stable adhesion and corrosion resistance, ensuring that it can adhere tightly to the outside of the steel structure column 1 and the steel structure base 3 and cover the weld 7 for anti-corrosion protection. Simultaneously, it ensures that the waterproof liner 5 has good and stable water-proof capability, ensuring that it can isolate and protect the anti-corrosion liner 6 and the weld 7. Further optionally, both the anti-corrosion liner 6 and the waterproof liner 5 are wrapped at least a full circumference to ensure that their circumferential lengths meet design requirements. Furthermore, the top edge of the waterproof liner 5 is higher than the top edge of the anti-corrosion liner 6, and the lower edge of the waterproof liner 5 extends beyond the lower edge of the anti-corrosion liner 6, so that the dimensions of the waterproof liner 5 can completely cover and protect the anti-corrosion liner 6.
[0025] See Figures 1-7 As shown, the top of the rectangular clamp 203 is higher than the top edge of the waterproof outer liner 5, and the bottom of the rectangular clamp 203 is lower than the top edge of the anti-corrosion inner liner 6. This arrangement allows the rectangular clamp 203 to stably tighten and constrain the waterproof outer liner 5 and its top outer periphery. Optionally, each clamping stud 404 has a coaxially detachable anti-detachment cap 405 with an outer diameter larger than the guide hole 406. Reinforcing ribs 407 are fixedly connected to the joint between the mounting plate 401 and the rectangular clamp 203, and these reinforcing ribs 407 do not interfere with the locking nut 403. This arrangement firstly prevents the top of the clamping stud 404 from accidentally detaching from the guide hole 406 using the anti-detachment cap 405, and secondly, enhances the stability and anti-deformation capability of the mounting plate 401 after it is fixed flat using the reinforcing ribs 407. Optionally, all pressure plates 402 are U-shaped plates, and the front and rear pressure plates 402 are aligned to form a complete rectangular frame. The outer edge of the pressure plate 402 extends beyond the lower edge of the waterproof outer liner 5, while the inner edge of the pressure plate 402 does not extend beyond the outer edge of the anti-corrosion inner liner 6. This arrangement ensures that the pressure plates 402 can stably tighten and constrain the waterproof outer liner 5 and its top outer periphery. Furthermore, the outer periphery of the clamping studs 404 are all Tang-style threads, and each clamping stud 404 has two locking nuts 403 with opposite directions of rotation. This arrangement facilitates the formation of a Tang-style anti-loosening thread structure by having each clamping stud 404 engage with two locking nuts 403 with opposite directions of rotation, preventing the locking nuts 403 from loosening naturally after tightening.
[0026] Using the above structure, specifically in practice, because an anti-corrosion inner lining 6 is wrapped around the weld 7 between the steel structure column 1 and the steel structure base 3, and a waterproof outer lining 5 is wrapped around the outside of the anti-corrosion inner lining 6, and the top periphery of the anti-corrosion inner lining 6 and the waterproof outer lining 5 are tightened and constrained by the circumferential clamping component 2, and the bottom of the anti-corrosion inner lining 6 and the waterproof outer lining 5 are tightly constrained from top to bottom by the downward pressing and tightening component 4, stable anti-corrosion and waterproof protection of the weld 7 can be achieved by adding an anti-corrosion inner lining 6 and a waterproof outer lining 5 around the weld 7, which helps to ensure the stable and reliable position of the weld 7. Furthermore, because the anti-corrosion inner lining 6 is made of epoxy resin impregnated carbon fiber cloth, This ensures that the anti-corrosion liner 6 has good and stable adhesion and corrosion resistance, guaranteeing that it can adhere tightly to the outside of the steel structure column 1 and the steel structure base 3 and cover the weld 7 for corrosion protection. Simultaneously, since the waterproof outer liner 5 is a rubber bushing, it possesses good and stable water-proofing capabilities, ensuring that it can isolate and protect the anti-corrosion liner 6 and the weld 7, thus extending the service life of the anti-corrosion liner 6. Furthermore, the rectangular clamp 203 of the circumferential clamping assembly 2, combined with the bolted connectors 201 inserted through the connecting flaps 202 on both sides, allows for... The top outer periphery of the anti-corrosion liner 6 and the waterproof liner 5 is stably tightened and constrained. This can be achieved by sequentially removing the bolt connector 201 and the rectangular clamp 203. The tightening and releasing of the top outer periphery of the anti-corrosion liner 6 and the waterproof liner 5 is simple and easy to implement. This facilitates preventing loosening and water seepage after tightening the top outer periphery of the anti-corrosion liner 6 and the waterproof liner 5, and also facilitates subsequent maintenance and replacement after loosening the top outer periphery of the anti-corrosion liner 6 and the waterproof liner 5. Furthermore, since the circumferential clamping assembly 2 is equipped with downward pressing and tightening components 4 at both the front and rear positions, then… By tightening the locking nuts 403 of the pressing and clamping assembly 4 onto the bottom surface of the mounting plate 401, the pressure plate 402 can tightly press and constrain the bottom of the anti-corrosion lining 6 and the waterproof outer lining 5 from top to bottom. At the same time, the pressing and clamping state of the pressure plate 402 on the bottom of the anti-corrosion lining 6 and the waterproof outer lining 5 can be released simply by unscrewing the locking nuts 403 away from the bottom surface of the mounting plate 401. The pressing and clamping method on the bottom of the anti-corrosion lining 6 and the waterproof outer lining 5 is simple and easy to implement. It is convenient to prevent loosening and water leakage after pressing and clamping the bottom of the anti-corrosion lining 6 and the waterproof outer lining 5. It is also convenient to loosen the bottom of the anti-corrosion lining 6 and the waterproof outer lining 5 for maintenance and replacement in the future.
