Technical Field

[0001] This utility model relates to the field of steel structure installation technology, and in particular to a positioning bracket for steel structure installation. Background Technology

[0002] Steel structures are structures made of steel materials and are one of the main types of building structures. The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of steel sections and steel plates. Rust removal and prevention processes such as silanization, pure manganese phosphating, water washing and drying, and galvanizing are used. The components or parts are usually connected by welds, bolts or rivets. I-beams are often used for construction and installation in factories or industrial areas.

[0003] During the installation of steel structures, especially the hoisting and installation of crossbeam steel structures, after the crossbeam steel structure is hoisted above the vertical steel structure, due to the weight of the steel structure itself, the position can only be adjusted by using a crane. During the crane hoisting process, the back-and-forth adjustment range is generally large, making it difficult to achieve precise positioning and unable to make minor position adjustments to the crossbeam steel structure. Therefore, a positioning bracket for steel structure installation is needed. Utility Model Content

[0022] Example: Refer to Figure 1-5 A positioning bracket for steel structure installation includes a fixed steel structure 1 and an installation I-beam 2. The installation I-beam 2 is located above the fixed steel structure 1 and is used for mounting beams onto the fixed steel structure 1. When the installation I-beam 2 is installed on the fixed steel structure 1, a hoisting device is used to hoist the installation I-beam 2 onto the fixed steel structure 1. A first U-shaped connecting block 3 and a second U-shaped connecting block 4 are provided on the outer side of the fixed steel structure 1. A fastening bolt 5 connects the first U-shaped connecting block 3 and the second U-shaped connecting block 4. Wedge-shaped grooves 6 are formed on the inner walls of both the first U-shaped connecting block 3 and the second U-shaped connecting block 4, and are connected to the fixed steel structure 1 by a fastening bolt 5. The wedge-shaped compression block 7 is used to clamp the first U-shaped connecting block 3 and the second U-shaped connecting block 4 on both sides of the fixed steel structure 1, and the fastening bolt 5 is used to achieve a stable connection between the connecting block and the fixed steel structure 1. The wedge-shaped compression block 7 is located between the connecting block and the fixed steel structure 1. The wedge-shaped compression block 7 can provide compression force. When the first U-shaped connecting block 3 and the second U-shaped connecting block 4 move down, the wedge-shaped compression block 7 can provide compression force, thereby preventing the first connecting block 3 and the second connecting block 4 from moving down, and the connection stability is better. After the first connecting block 3 and the second connecting block 4 are installed, the base of the positioning bracket is formed.

[0023] Specifically, side support plates 8 are fixedly installed on the top of both the first U-shaped connecting block 3 and the second U-shaped connecting block 4.

After the I-shaped steel 2 is lifted, the telescopic cylinder 19 on the push adjustment assembly is activated to drive the movable block 9 to adjust its position back and forth. The telescopic cylinder 19 can achieve fine adjustment of the distance, thereby making a small adjustment to the end of the I-shaped steel 2, which is convenient for positioning and installation of the I-shaped steel 2. The adjustment is relatively convenient. The positioning pin 23 is provided to facilitate the connection between the upper drive plate 20 and the lower drive plate 21. The movable block 9 on the side support plate 8 is easy to remove and place, and is convenient to disassemble and assemble.

[0025] In use: The first U-shaped connecting block 3 and the second U-shaped connecting block 4 are clamped on both sides of the fixed steel structure 1, and the fastening bolts 5 are used to achieve a stable connection between the connecting blocks and the fixed steel structure 1. The wedge-shaped extrusion block 7 provides extrusion force, thereby preventing the first connecting block 3 and the second connecting block 4 from moving down, resulting in better connection stability. The L-shaped hanging plate 15 on the hanging assembly is adjusted to clamp the installation I-beams 2 of different widths. The lifting cylinders 12 on both sides are started to lift the horizontal lifting rod 13, thereby lifting the hanging installation I-beams 2. The telescopic cylinder 19 on the push adjustment assembly is started to drive the moving block 9 to adjust its position back and forth. The telescopic cylinder 19 can achieve fine adjustment of the distance, thereby allowing for a small adjustment of the end of the installation I-beams 2, which is convenient for positioning and installation of the installation I-beams 2. The adjustment is relatively convenient.
