Description

Technical Field

[0001] The present invention relates to the technical field of installation and opening / closing of large steel structure bolt gusset plates, and specifically provides a device for installing and opening / closing large steel structure bolt gusset plates. Background Art

[0002] The device for installing and opening / closing large steel structure bolt gusset plates is a device for splicing and supporting steel structures in buildings.

When the device for installing and opening / closing large steel structure bolt gusset plates is used, it needs to be installed with external steel structures. Since the connection ports of the device for installing and opening / closing large steel structure bolt gusset plates are set in advance, misalignment is likely to occur during installation with steel structures, resulting in inability to install, and thus the device for installing and opening / closing large steel structure bolt gusset plates has limitations in use. Moreover, the device for installing and opening / closing large steel structure bolt gusset plates will adjust the rotation angle according to the connected steel structure during use. After the angle is rotated, there is no positioning, and it is easy to rotate back during installation, requiring readjustment, which increases the difficulty of using the device for installing and opening / closing large steel structure bolt gusset plates. In addition, the device for installing and opening / closing large steel structure bolt gusset plates can only be installed on the plane of the steel structure. If there is a columnar steel structure, columnar connecting plates need to be welded, resulting in a single installation form of the device for installing and opening / closing large steel structure bolt gusset plates. At the same time, the length of the gusset plate is limited, and since the device for installing and opening / closing large steel structure bolt gusset plates is already fixed to the steel structure, it cannot meet the installation requirements. It is necessary to disassemble and replace the entire device for installing and opening / closing large steel structure bolt gusset plates, resulting in troublesome use of the device for installing and opening / closing large steel structure bolt gusset plates.

After rotating the angle, the bent plate 301 is pushed towards the concave plate 6 on the outer wall of the rotating plate 301, so that the insertion plate 304 is inserted into the corresponding notch on the outer wall of the concave plate 6. Then, the first bolt 303 is threadedly connected to the rotating plate 301 through the bent plate 302 to fix the position of the bent plate 302, reducing the use difficulty of the opening and closing device for the large bolt gusset plate of the steel structure.

[0037] The fixing structure 4 includes a bracket 401, a frame 402, and a second bolt 403.

[0040] By driving the screw rod 503 to rotate to the right through the grip 504 in the adjustment structure 5, the rotating screw rod 503 drives the vertical plate 502 to gradually move the second node plate 501 to the right inside the inner wall of the first node plate 8, realizing the overall lengthening of the node plate to meet the installation requirements without the need for overall replacement, making the installation and opening / closing device of the large bolt node plate of the steel structure convenient to use.

[0041] When using the installation and opening / closing device of the large bolt node plate of the steel structure, first make the rear end surface of the vertical plate 1 fit with the surface of the steel structure. Then, the vertical cylinder 202 rotates on the outer wall of the double-headed stud 201, and further cooperates with the sleeve plate 203 to drive the connecting plate 204 to slide up and down inside the chute groove 7, aligning the position of the connecting plate 204 with the connection port on the steel structure. Then, the connecting bolt passes through the connecting plate 204 and is connected to the steel structure. Then, the rotating plate 301 rotates inside the concave plate 6, and further drives the first node plate 8 to rotate at an angle. After rotating the angle, push the bent plate 301 towards the concave plate 6 on the outer wall of the rotating plate 301, so that the insertion plate 304 is inserted into the corresponding notch on the outer wall of the concave plate 6. Then, the first bolt 303 is threadedly connected to the rotating plate 301 through the bent plate 302 to fix the position of the bent plate 302. The rotated first node plate 8 is in contact with the surface of the steel structure on the other side. Then, the connecting bolt passes through the first node plate 8 and is connected to the steel structure. When the length of the first node plate 8 is insufficient, cooperate with the two grips 504 to drive the screw rod 503 to rotate to the right. The rotating screw rod 503 drives the vertical plate 502 to gradually move the second node plate 501 to the right inside the inner wall of the first node plate 8, realizing the overall lengthening of the node plate to meet the installation requirements. When installing the installation and opening / closing device of the large bolt node plate of the steel structure with the column steel structure, make the left side of the vertical plate 1 fit with the steel structure. Then, the inner wall of the frame 402 is inserted into the outer wall of the steel structure. Then, the right side of the frame 402 is inserted into the inner wall of the support 401. Then, the second bolt 403 is threadedly connected to the outer wall of the frame 402 through the support 401, and the column steel structure is clamped by the frame 402 and the vertical plate 1 to complete the installation.
