Description

Technical Field

[0001] The utility model belongs to the technical field of anti-corrosion structures of steel structure welds, and more specifically, particularly relates to an anti-corrosion protection structure of steel structure welds. Background Art

[0002] In civil engineering, the connection of steel structure components is a crucial link. Common connection methods such as steel pipe piles and I-beams are usually connected by on-site welding. However, this connection method has a significant problem: the steel in the weld and its surrounding area will be affected by the high temperature of the welding fire during the welding process, causing the originally applied anti-corrosion coating to be destroyed.

[0003] The main function of anti-corrosion coating is to protect steel from erosion by environmental corrosive gases or water. Once the coating is damaged, the steel structure is exposed to the corrosive environment, which becomes the weak link of the steel structure and greatly shortens its service life.

[0004] At present, the industry usually takes the measure of re-applying anti-corrosion treatment after welding to solve the anti-corrosion problem of welds and surrounding areas. However, this method has many shortcomings. First, the process of re-applying anti-corrosion materials 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 re-applied, the anti-corrosion effect will be greatly reduced because the organizational structure of the steel may change during the welding process.

[0028] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0029] like Figure 1 As shown, the specific technical solution of the anti-corrosion protection structure of a steel structure weld provided in the embodiment of the present application is as follows:

[0030] The anti-corrosion protection layer 7 is provided on the weld and its vicinity to completely cover the weld to prevent it from being exposed; the anti-corrosion protection layer 7 is formed by impregnating carbon fiber cloth with epoxy resin;

[0031] Auxiliary fixing structure, the auxiliary fixing structure fixes the I-shaped plate 2 to the support plate 3.

[0032] The utility model provides an anti-corrosion protection structure for a weld of a steel structure. Compared with the prior art, the anti-corrosion protection layer 7 is formed by epoxy resin impregnated carbon fiber cloth. Epoxy resin is a high-strength, high-viscosity adhesive that can tightly bond the carbon fiber cloth to the weld to form a strong and durable structural layer. Carbon fiber cloth is known for its excellent tensile strength and lightweight properties, and can effectively enhance the mechanical properties of pavement bricks. Therefore, the anti-corrosion protection layer 7 can form a stable anti-corrosion protection layer and has a reinforcement function.

[0033] In addition, the provision of the anti-corrosion protection layer 7 also improves the waterproof performance of the weld. Since the anti-corrosion protection layer 7 tightly covers the weld, it can effectively prevent moisture from penetrating into the interior of the brick body, reducing damage and aging caused by moisture erosion.

[0034] In another embodiment of the present application, Figure 3 As shown, the auxiliary fixing structure includes two single-sided fixing members 1 and a weld protection structure 4; the two single-sided fixing members 1 are respectively arranged on both sides of the I-shaped plate 2; the single-sided fixing member 1 includes a vertical plate 11 and a horizontal plate 12; the vertical plate 11 is connected to the support plate 3 of the steel structure through a fastener 111; the horizontal plate 12 is supported under the wing plate 21 of the I-shaped plate 2 of the steel structure; one side of the weld protection structure 4 is connected to the single-sided fixing member 1, and the other side of the weld protection structure 4 abuts against the web 22 of the I-shaped plate 2. The single-sided fixing member 1 of the utility model enables the vertical plate to be quickly and firmly connected to the support plate of the steel structure through the presence of the fastener, and then supports the wing plate 21 of the I-shaped plate 2 of the steel structure through the horizontal plate 12; in addition, the weld protection structure 4 of the utility model can not only improve the strength and stability of the single-sided fixing member 1, but also enable it to effectively protect the weld and prevent external damage.

[0035] In another embodiment of the present application, Figure 3 As shown, the vertical plate 11 is provided with a slot 112, and the slot 112 is engaged with the wing plate 21. Specifically, the shape and size of the slot 112 are designed according to the shape and size of the wing plate 21 to ensure that they can fit tightly. When the wing plate 21 is inserted into the slot 112, its edge will be fixed by the inner wall of the slot 112, thereby preventing the wing plate 21 from falling off or shaking from the vertical plate 11. In addition, due to the tight fit between the slot 112 and the wing plate 21, the gravity of the I-shaped plate 2 can be shared.

[0036] In another embodiment of the present application, Figure 3As shown, the weld protection structure 4 is provided with a glue injection hole 41. The glue injection hole 41 is usually located at an appropriate position of the weld protection structure 4 so that sealant or other protective materials can be effectively injected around the weld. The sealant or other protective materials injected through the glue injection hole 41 can form a barrier around the weld to prevent moisture, gas and other harmful substances from invading the weld, thereby protecting the weld from corrosion and damage.

[0037] In addition, the injection hole 41 can also be used to regularly inspect and maintain the weld protection structure 4. Through the injection hole 41, the internal condition of the weld protection structure 4 can be conveniently inspected, and protective materials such as sealants can be replenished or replaced when necessary. It should be noted that the design and use of the injection hole 41 should be determined according to the specific weld protection structure 4 and the use environment. For example, the size and position of the injection hole 41 should be determined according to the size of the weld and the properties of the protective material to ensure that the sealant or other protective materials can be effectively injected and evenly distributed around the weld.

[0038] In another embodiment of the present application, Figure 4 As shown, a fall arrester 5 is provided on the upper side of the I-shaped plate 2. In another embodiment of the present application, as shown in FIG. Figure 4 As shown, the fall arrester 5 includes a mounting plate 51, a plurality of lifting rods 52 and a plurality of limiting plates 53; a plurality of lifting rods 52 are provided on one side of the horizontal plate 12, and the upper ends of the lifting rods 52 move up and down in the movable holes of the mounting plate 51; a limiting plate 53 is provided on the upper end of each lifting rod 52. When the welding between the support plate 3 and the I-shaped plate 2 fails due to corrosion, the I-shaped plate 2 may fall, and at this time, the lifting rods 52 fall, and finally the lifting rods 52 will be hung on the mounting plate 51 under the action of the limiting plates 53.

[0039] In another embodiment of the present application, Figure 4 As shown, a pressure patch is provided below the limit plate 53, and the pressure patch is connected to an alarm. When the lifting rod 52 falls, the lower surface of the limit plate 53 will fit the mounting plate 51, so that the pressure patch is compressed. The pressure patch can detect the pressure change on the limit plate 53 in real time and convert it into an electrical signal for output. When the pressure on the limit plate 53 exceeds a preset threshold, the pressure patch will trigger the alarm and emit an audible and visual alarm signal to promptly remind the operator to take countermeasures.

[0040] In another embodiment of the present application, Figure 4 As shown, a rib plate 121 is provided under each horizontal plate 12 to improve the installation strength of the horizontal plate 12 .

[0041] In another embodiment of the present application, Figure 4 As shown, the lifting rod 52 is made of polymer material or aluminum alloy, and the weight of the lifting rod 52 is reduced as much as possible to avoid burdening the horizontal plate 12.

[0042] It is understood that the present invention is described by some embodiments, and those skilled in the art are aware that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention. In addition, under the teachings of the present invention, these features and embodiments may be modified to adapt to specific circumstances and materials without departing from the spirit and scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the scope of protection of the present invention.
