Technical Field

[0001] The utility model relates to the field of special-shaped steel structures, in particular to a welding auxiliary clamping component of the special-shaped steel structure. Background Art

[0002] Steel structures are made of steel and are one of the main types of building structures. Welding provides strong and reliable connections and is widely used in large factories, stadiums, high-rise buildings, bridges, and other fields. Welding is a process of joining metals using heat, high temperature, or high pressure. During welding, the two welded surfaces must be aligned.

[0003] When existing special-shaped steel is welded into strips or blocks, it is not easy to fix it and it is difficult to keep the welding surface aligned. In addition, it is difficult to clamp different special-shaped steels, which makes the welding operation more difficult and thus affects the welding effect. Utility Model Content

[0028] The second embodiment is different from the first embodiment in that:

[0029] An open slot 101 is provided on the limiting plate 1. In the horizontal direction, the cross section of the open slot 101 is in a "T"-shaped structure. An insert block 201 is provided at the connecting end of the guide rod 2 and the limiting plate 1. The insert block 201 is plugged into the open slot 101. The plugging and matching of the insert block 201 and the open slot 101 are used to limit the guide rod 2. During the installation of the clamping plate 3, a fixed plate 203 is slid on the outside of the guide rod 2. A socket 301 is provided on the back side of the clamping plate 3. Sockets 5 are provided on both the limiting plate 1 and the fixed plate 203. The plug socket 301 is plugged into the socket 5. By plugging the plug socket 301 into the socket 5, the clamping plate 3 and the limiting plate 1 can be connected. After the connection, the guide rod 2 is prevented from moving along the length direction of the plug block 201, thereby limiting the position of the guide rod 2. The special-shaped steel structure is placed between the two clamping plates 3. By utilizing the cooperation between the surface of the clamping plate 3 and the special-shaped steel and screwing the fixing nut 202, the two clamping plates 3 are clamped close to each other, which can ensure that the clamping plate 3 clamps the special-shaped steel.

Furthermore, the fixing nut 202 is rotatably connected to the fixing plate 203.

[0031] The third embodiment is different from the first embodiment in that:

[0032] The two limit plates 1 are respectively provided with a sliding sleeve 103 and a sliding rod 102. The sliding sleeve 103 and the sliding rod 102 are slidably matched.

The nut sleeve 401 is threadedly connected to the two threaded rods 402. The movable inner parts of the two threaded rods 402 are respectively connected to the two limit plates 1. When the nut sleeve 401 is rotated, the threaded connection can be used to enable the two threaded rods 402 to extend into the nut sleeve 401 or pass through the inside of the nut sleeve 401, thereby realizing the adjustment of the overall length of the extension rod 4. The outer side of the nut sleeve 401 is provided with anti-slip grooves to facilitate the rotation of the nut sleeve 401.
