Description

Technical Field

[0001] This utility model relates to the field of steel structure technology, specifically to an installation device for corrosion-resistant steel structures. Background Technology

[0002] In modern architecture and various engineering projects, steel structures have become an extremely important structural form due to their outstanding advantages, such as high strength, lightweight properties, and rapid construction capabilities. Within steel structure systems, reliable connection technology is the core element ensuring the stability and safety of the overall structure; the sophistication of the connection technology directly determines the performance of the steel structure.

[0003] Existing steel structure connection methods that rely solely on multiple sets of bolts generally lack effective sealing measures. When exposed to rain, the metal components at the steel structure connection points come into contact with the rainwater, and over time, the connection points will quickly rust and corrode. This not only significantly reduces the strength of the materials but also seriously damages the durability of the steel structure connection points. In the long run, the structural damage caused by rust will gradually accumulate, seriously affecting the stability of the steel structure.

[0004] In view of the above, this application is hereby submitted. Utility Model Content

[0005] The purpose of this invention is to provide an installation device for corrosion-resistant steel structures to solve the problems mentioned in the background art.

The installation device for corrosion-resistant steel structures includes steel structure A and steel structure B. A protective cover is fitted on steel structure A and steel structure B. Steel structure A, steel structure B and protective cover are fixed together by fixing bolts. A protective shell is also provided on the side wall of the protective cover. The protective shell covers the outside of the fixing bolts. A locking component is provided on the protective shell. The protective shell is fixed to the protective cover by the locking component.

[0007] Furthermore, the steel structure A, steel structure B, and protective cover are all provided with corresponding through holes, and the fixing bolts are inserted into the through holes.

[0008] Furthermore, the outer walls of both steel structure A and steel structure B are fitted to the inner wall of the protective cover, and a second sealing strip is also installed on the inner wall of the protective cover.

[0009] Furthermore, the protective shell includes a shell and a first sealing strip. The shells are symmetrically and slidably disposed on the side wall of the protective cover. The first sealing strip is installed on the end face of the opening end of the shell. The two opposing shells can slide relative to each other to close the opening end of the shell.

[0010] Furthermore, a limiting block is provided on the side of the housing that is in contact with the side wall of the protective cover, and a limiting groove is provided on the side wall of the protective cover for the limiting block to slide.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-4 This utility model provides a technical solution: an installation device for corrosion-resistant steel structures, including steel structure A1 and steel structure B2, with a protective cover 3 fitted on steel structure A1 and steel structure B2. Steel structure A1, steel structure B2 and protective cover 3 are fixed together by fixing bolts 8. A protective shell 5 is also provided on the side wall of the protective cover 3, covering the outside of the fixing bolts 8. A locking component 6 is provided on the protective shell 5, and the protective shell 5 is fixed to the protective cover 3 by the locking component 6.

[0024] Specifically, the protective cover 3 can provide overall protection for the connection between steel structure A1 and steel structure B2, reducing the impact of the external environment on the connection; the protective shell 5 covers the fixing bolts 8 and, together with the locking component 6, fixes them to the protective cover 3, which can effectively prevent rainwater and other substances from directly contacting the fixing bolts 8, reduce the risk of bolt rusting, enhance the stability and durability of the connection, and ensure the overall safety of the steel structure.

[0025] See Figures 1-3 Steel structure A1, steel structure B2 and protective cover 3 are all provided with corresponding through holes 9, and fixing bolts 8 are inserted into the through holes 9.

[0026] Specifically, the corresponding setting of the perforation 9 facilitates the installation of the fixing bolt 8, improves installation efficiency, and ensures the accuracy of the connection of each component, which is conducive to ensuring the stability of the entire connection structure.

[0027] See Figure 2 The outer walls of steel structures A1 and B2 are both fitted to the inner wall of the protective cover 3, and a second sealing strip 4 is also installed on the inner wall of the protective cover 3.

[0028] Specifically, the fitted structure and the second sealing strip 4 enhance the sealing between the protective cover 3 and the steel structure A1 and steel structure B2, effectively preventing rainwater and other external substances from entering the steel structure connection, further improving corrosion resistance and extending the service life of the steel structure.

[0029] See Figure 4 The protective shell 5 includes a shell 51 and a first sealing strip 53. The shells 51 are symmetrically and slidably arranged on the side wall of the protective cover 3. The first sealing strip 53 is installed on the end face of the opening end of the shell. The two opposing shells 51 can slide relative to each other to close the opening end of the shell 51.

[0030] Specifically, the sliding housing 51 is designed to facilitate installation and disassembly, and to make it easy to maintain the fixing bolts 8; when the housing 51 is closed, the first sealing strip 53 enhances the sealing performance of the protective housing 5 itself, and better protects the fixing bolts 8 from external corrosion.

[0031] See Figure 3 and Figure 4 A limiting block 52 is provided on the side of the housing 51 that is in contact with the side wall of the protective cover 3, and a limiting groove 10 is provided on the side wall of the protective cover 3 for the limiting block 52 to slide.

[0032] Specifically, the cooperation between the limiting block 52 and the limiting groove 10 ensures the stability and accuracy of the sliding of the housing 51, enabling the protective housing 5 to open and close reliably and ensuring the protective effect on the fixing bolt 8.

[0033] See Figure 4 The locking assembly 6 includes a pressure rod 61 slidably connected to the housing 51. One end of the pressure rod 61 extending into the housing 51 is connected to a baffle 62. A return spring 63 is sleeved on the pressure rod 61. A connecting rod 65 is rotatably connected to the side wall of the baffle 62. A locking rod 64 is hinged to the other end of the connecting rod 65. The locking rod 64 is slidably connected to the side wall of the housing 51. A locking groove 7 is provided on the protective cover 3 for the locking rod 64 to be inserted.

[0034] Specifically, the return spring 63 drives the baffle 62 to move, and the baffle 62 pushes the locking rod 64 to slide in the sliding port on the side wall of the housing 51 through the connecting rod 65, inserting it into the locking groove 7 on the protective cover 3 to complete the locking. Pulling the pressure rod 61 compresses the return spring 63, causing the relevant components to reset, and the locking rod 64 is pulled out to release the lock.

[0035] See Figure 4 One end of the return spring 63 is connected to the inner wall of the housing 51, and the other end of the return spring 63 is connected to the baffle 62. In the initial state, the return spring 63 causes the pressure rod 61 to have a tendency to slide into the housing 51.

[0036] Specifically, the return spring 63 drives the locking rod 64 to insert into the locking groove 7 and maintain the lock. The setting of the return spring 63 provides the locking component 6 with the power for automatic locking. It can ensure the locking of the protective shell 5 and the protective cover 3 without additional operation, which improves the convenience and reliability of the device.

[0037] See Figure 4 A sliding opening is provided through the side wall of the housing 51, and the locking rod 64 is slidably connected to the inside of the sliding opening. The outer wall of the locking rod 64 is in contact with the inner wall of the sliding opening.

[0038] Specifically, a sliding opening is provided through the side wall of the housing 51, and the locking rod 64 slides within the sliding opening with its outer wall fitting against the inner wall of the sliding opening, ensuring the smoothness and sealing of the sliding of the locking rod 64. The fitted sliding structure ensures the stability of the locking rod 64 during the sliding process, prevents foreign objects from entering the locking assembly 6 and affecting its normal operation, and enhances the sealing of the protective housing 5, further improving the protection capability of the fixing bolt 8.

[0039] Working principle:

[0040] Basic connection: Using fixing bolts 8, which pass through the corresponding holes 9 on steel structure A1, steel structure B2 and protective cover 3, steel structure A1 and steel structure B2 are connected, and protective cover 3 is securely fitted on the outside of the connection between the two.

[0041] Sealing and Protection: The inner wall of the protective cover 3 is fitted to the outer walls of steel structures A1 and B2. The second sealing strip 4 on the inner wall fills the gaps to form a primary seal, preventing external substances from contacting the steel structure connections. For the critical component of the fixing bolt 8, which is prone to rust, a sliding protective shell 5 is installed. The protective shell 5 consists of two symmetrical shells 51, which slide relative to each other through a limiting block 52 within a limiting groove 10, closing the open end and covering the fixing bolt 8. The first sealing strip 53 on the end face of the open end of the shell 51 further enhances the sealing performance of the protective shell 5 when closed.

[0042] Locking Mechanism: When the protective shell 5 is closed, it is fixed to the protective cover 3 by the locking component 6. The return spring 63 drives the baffle 62 to move. The baffle 62 pushes the locking rod 64 to slide in the sliding port on the side wall of the shell 51 through the connecting rod 65, and inserts it into the locking groove 7 on the protective cover 3 to complete the locking. Pulling the pressure rod 61 compresses the return spring 63, drives the relevant components to reset, and the locking rod 64 is pulled out to release the lock.

[0043] As described above, although the present invention has been shown and described with reference to specific preferred embodiments, it should not be construed as limiting the present invention itself. Various changes in form and detail may be made to the present invention without departing from the spirit and scope of the appended claims.
