Description

Technical Field

[0001] This utility model relates to the technical field of flange parts, specifically a multifunctional connecting flange for steel structures. Background Technology

[0002] Steel structures are structures made of steel materials and are one of the main types of building structures. The structure mainly consists of steel beams, steel columns, steel trusses, and other components made of shaped steel and steel plates. Rust removal and prevention processes such as silanization, pure manganese phosphating, water washing and drying, and galvanizing are used. During the connection process, steel structures typically use connecting flanges to connect and connect the steel pipes at both ends.

[0003] Existing connecting flanges typically use flanges and fasteners to bolt steel pipes together at both ends. However, the thickness of the flange cannot be adjusted, meaning it cannot be adjusted to accommodate the gap between the pipe and the connecting flange. This reduces the sealing effect after the flange connection. Furthermore, the different positions of the bolt holes between the flange and the pipe require different flanges to be used, causing inconvenience to the connection operation between the steel pipe and the connecting flange.

[0004] According to the announcement number CN221402114U, a flange includes a pipe and a disc sleeved on the pipe. The disc is characterized in that: the disc is connected to the pipe via a connecting assembly; the connecting assembly includes four spaced-apart connecting plates fixedly connected to the pipe and evenly distributed circumferentially on the outer surface of the pipe; a connecting groove matching the connecting plates is provided on the rear side of the disc; the disc is fixed to the pipe via a fixing assembly; and a guiding assembly and a positioning assembly are provided on the pipe for guiding the disc when it is sleeved onto the pipe. The beneficial effect of this invention is that by providing a connecting assembly, the disc of the flange can be easily replaced, allowing for adaptation to different equipment by replacing discs of different specifications.

[0005] As described above, the flange thickness cannot be adjusted, which means the flange thickness cannot be adjusted according to the gap size between the steel pipe and the connecting flange. This reduces the sealing effect after the flange connection. In addition, the bolt hole positions between the flange and the pipe are different, requiring the flange to be replaced with one that is installed in a different position. This causes inconvenience to the connection operation between the steel pipe and the connecting flange. Therefore, we need to propose a multi-functional connecting flange for steel structures. Utility Model Content

[0006] The purpose of this utility model is to provide a multifunctional connecting flange for steel structures. Through the stacking structure, several flanges can be stacked, allowing the flange thickness to be adjusted according to the gap between the steel pipe and the connecting flange. Rotating the adjustment component moves the mounting base within the adjustment hole, thus adjusting the position of the mounting hole. This allows the connecting flange thickness to be adjusted according to the gap size, increasing the sealing effect after flange connection. Furthermore, the connecting hole position on the connecting flange can be adjusted according to the bolt hole position of the steel pipe, facilitating the connection operation between the steel pipe and the connecting flange, thereby solving the problems mentioned in the background art.

[0010] Preferably, the outer surface of the button block is fixedly connected with anti-slip protrusions, and the anti-slip protrusions are arranged in several groups, which are distributed around the center on the outer surface of the button block.

[0011] Preferably, the superimposed structure includes a connecting plate, which is rotatably connected to both sides of the top of the flange via a damping shaft.

[0023] 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.

[0024] Please see Figure 1-4 This utility model provides a technical solution: a multi-functional connecting flange for steel structures, including a flange 1, with connecting seats 2 fixedly connected to both sides of the flange 1. An adjustment hole 3 is provided on the upper surface of the connecting seat 2. An adjustment component 4 for adjusting the installation position is provided at the end of the connecting seat 2 away from the flange 1. One end of the adjustment component 4 passes through the connecting seat 2 and is provided with a mounting seat 5. The mounting seat 5 is located in the inner cavity of the adjustment hole 3. An installation hole 6 is provided on the surface of the mounting seat 5. A connecting hole 7 is provided on the surface of the flange 1. A superimposed structure 8 for increasing the flange connection thickness is installed on the flange 1.

[0025] When the gap at the connection is large, the thickness of the flange 1 is increased by the cooperation of several sets of flanges 1 through the superposition structure 8 according to the width of the gap. Then, according to the position of the bolt holes of the steel pipe, the adjusting component 4 is rotated to push the mounting seat 5 to move, so that the mounting seat 5 moves within the adjusting hole 3, thereby adjusting the position of the mounting hole 6. This allows the thickness of the connecting flange to be adjusted according to the size of the gap, increasing the sealing effect after the flange connection. It also allows the position of the connecting hole 7 on the connecting flange to be adjusted according to the position of the bolt holes of the steel pipe, providing convenience for the connection operation between the steel pipe and the connecting flange.

[0026] The adjusting assembly 4 includes a threaded sleeve 41, which is inserted and fixed to the surface of the connecting seat 2. One end of the threaded sleeve 41 communicates with the inner cavity of the adjusting hole 3. A screw 42 is threadedly connected to the inner cavity of the threaded sleeve 41. One end of the screw 42 is rotatably connected to the surface of the mounting seat 5 through a bearing. The other end of the screw 42 is fixedly connected to a button 43. Rotating the button 43 drives the screw 42 to rotate. Through the cooperation between the screw 42 and the threaded sleeve 41, the screw 42 rotates and pushes the mounting seat 5 to move, so that the mounting seat 5 moves within the adjusting hole 3, thereby adjusting the position of the mounting hole 6.

[0027] Both ends of the mounting base 5 are fixedly connected to sliders 9. The inner wall of the adjustment hole 3 is provided with a groove that matches the slider 9. The slider 9 is slidably connected to the inner cavity of the groove of the adjustment hole 3. The cooperation between the slider 9 and the groove supports both sides of the mounting base 5, thereby improving the stability of the mounting base 5 when it moves within the inner cavity of the adjustment hole 3.

[0028] Anti-slip protrusions 10 are fixedly connected to the outer surface of the button block 43. Several sets of anti-slip protrusions 10 are arranged around the center on the outer surface of the button block 43. The anti-slip protrusions 10 increase the friction between the worker's hand and the button block 43, making it easier for the worker to twist the button block 43 to drive the screw 42 to rotate. Through the cooperation of the screw 42 and the threaded sleeve 41, the screw 42 rotates and pushes the mounting seat 5 to move, so that the mounting seat 5 moves in the adjustment hole 3, realizing the adjustment of the position of the mounting hole 6. Finally, the bolt is passed through the bolt hole of the steel pipe and the mounting hole 6 to connect with the bolt hole on the other end of the steel pipe. This allows the thickness of the connecting flange to be adjusted according to the size of the gap, increasing the sealing effect after the flange is connected. The position of the connecting hole 7 on the connecting flange can be adjusted according to the position of the bolt hole of the steel pipe, providing convenience for the connection operation between the steel pipe and the connecting flange.

[0029] The stacked structure 8 includes a connecting plate 81, which is rotatably connected to both sides of the top of the flange 1 via a damping shaft. The connecting plate 81 is L-shaped. A locking block 82 is fixedly connected to the bottom of the flange 1. The locking block 82 engages with the inner wall of the connecting plate 81. Several sets of flanges 1 are stacked. The connecting plate 81 is moved. When the inner wall of the connecting plate 81 is in contact with the surface of the locking block 82, the shape of the connecting plate 81 fixes the position of the connected flanges 1.

[0030] A support block 11 is fixedly connected to the upper surface of the flange 1, and a support groove 12 adapted to the support block 11 is opened on the lower surface of the flange 1. The inner cavity of the support block 11 and the support groove 12 are engaged and locked. Through the engagement of the support block 11 and the support groove 12, the phenomenon of angular and positional displacement after the flange 1 is connected is avoided, and the stability of the flange 1 after stacking is increased.

[0031] There are six sets of support blocks 11, which are distributed around the center on the upper surface of the flange 1. The support effect between the support blocks 11 and the flange plate is improved by setting the support blocks 11.

[0032] An annular sealing plate 13 is fixedly connected to the upper surface of the flange 1, and a sealing groove 14 adapted to the annular sealing plate 13 is opened on the lower surface of the flange 1. All six sets of support blocks 11 are located in the inner cavity of the annular sealing plate 13. Through the cooperation of the annular sealing plate 13 and the sealing groove 14, the sealing effect of several sets of flanges 1 stacked together is increased. At the same time, the annular sealing plate 13 can cover the connection of the steel pipe.

[0033] In practical use: When the gap at the connection is large, several sets of flanges 1 are stacked according to the width of the gap. After the flanges 1 are stacked, the connecting plate 81 is moved and the angle of the connecting plate 81 is adjusted so that the inner side wall of the connecting plate 81 is in contact with the surface of the clamping block 82 to fix the position of the flanges 1 after connection. Then, the knob block 43 is rotated.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
