Technical Field

[0001] This utility model relates to the field of steel structure beam-column connection technology, specifically to a support and reinforcement structure at the welded joint between a steel column and a beam. 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 steel pipes, structural steel, and steel plates, and employs rust removal and prevention processes such as silanization, pure manganese phosphating, water washing and drying, and galvanizing. The various components or parts are typically connected by welds, bolts, or rivets. Due to their light weight and simple construction, they are widely used in large factories, stadiums, high-rise buildings, bridges, and other fields.

[0003] During the construction of steel structures, to ensure the stability and safety of the steel structure, construction workers often use welding to connect the steel columns and beams. However, this method is prone to rusting and cracking, has low connection strength, and poses safety hazards. Furthermore, welding makes it inconvenient to disassemble the beams and columns later. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a support and reinforcement structure for the welded joint of steel columns and beams.

[0005] The steel column and beam weld joint support and reinforcement structure includes a square tube steel column and multiple I-beams. The side wall of the square tube steel column is provided with a connection port that mates with the I-beams. The outside of the square tube steel column is fitted with a connecting device that mates with the I-beams. A support device is fixedly installed at the bottom of the connecting device. A hoisting device that mates with the I-beams is installed at the top of the square tube steel column.

[0006] Furthermore, the connecting device includes a base plate and a top plate, which are fixedly connected by four evenly arranged L-shaped plates. A second connection port corresponding to the first connection port is provided between two adjacent L-shaped plates. Both the base plate and the top plate are provided with steel column sliding holes. The square tube steel column passes through the steel column sliding holes and is sleeved in the base plate and the top plate. The square tube steel column and the L-shaped plates are fixedly connected by connecting bolts.

[0007] Furthermore, the support device includes four support plates evenly fixedly arranged at the bottom of the base plate. The support plates and the bottom of the base plate are fixedly connected by multiple support ribs. The square tube steel column and the support plates are fixedly connected by support bolts.

[0008] Furthermore, the hoisting device includes a cover plate, a hoisting plate, and hoisting bolts. A limit block is fixedly provided at the bottom of the cover plate. The hoisting bolts pass through the cover plate and the limit block and are threadedly connected to the hoisting plate. The limit block and the hoisting plate cooperate with the inner hole of the square tube steel column.

[0009] Furthermore, the four corners of the cover plate are fixedly connected to the four corners of the top plate by lifting bolts.

[0010] In summary, this utility model has the following beneficial effects:

[0011] This invention involves fitting a connecting device onto the outside of a square tube steel column, ensuring a perfect match between the connecting device and the connection port. The invention uses a hoisting device to clamp the I-beam, and through its connection with the connecting device, keeps the I-beam as horizontal as possible, meeting construction requirements. The connecting device is connected to the square tube steel column, fixing its position, while a supporting device is connected to the square tube steel column, providing support strength for both the connecting device and the I-beam, making their positions more stable. This invention ensures the stability and safety of the connection between the square tube steel column and the I-beam, guarantees the horizontality of the I-beam, and is convenient to operate, install, and disassemble.

[0021] The present invention will be further described below with reference to the accompanying drawings:

[0022] like Figure 1-6 As shown, the steel column and beam weld joint support and reinforcement structure includes a square tube steel column 1 and multiple I-beam beams 2. The side wall of the square tube steel column 1 is provided with a connection port 3 that matches the I-beam beams 2. The outside of the square tube steel column 1 is fitted with a connecting device that matches the I-beam beams 2. A support device is fixedly installed at the bottom of the connecting device. The top of the square tube steel column 1 is provided with a hoisting device that matches the I-beam beams 2.

[0023] In this embodiment, a square steel column 1 is used to support four I-beams 2. A connecting device is fitted onto the outside of the square steel column 1, ensuring that the connecting device matches the connection port 3. A hoisting device is placed on top of the square steel column 1. The four I-beams 2 are inserted into the square steel column 1 after passing through the connecting device and connection port 3. The hoisting device clamps the four I-beams 2, and through its connection with the connecting device, the four I-beams 2 are kept as horizontal as possible to meet construction requirements. The connecting device is then connected to the square steel column 1 to fix its position. A supporting device is connected to the square steel column 1 to provide support strength for the connecting device and the I-beams 2, making their positions more stable. Preferably, one end of the I-beam 2 located inside the square steel column 1 is... Figure 2 The cut shown increases the contact area between the lifting device and the device, resulting in a more secure clamping.

[0024] The connecting device includes a base plate 4 and a top plate 5. The base plate 4 and the top plate 5 are fixedly connected by four evenly arranged L-shaped plates 7. A connecting port 2 8 corresponding to the connecting port 3 is provided between two adjacent L-shaped plates 7. Both the base plate 4 and the top plate 5 are provided with steel column sliding holes 6. The square tube steel column 1 passes through the steel column sliding holes 6 and is sleeved in the base plate 4 and the top plate 5. The square tube steel column 1 and the L-shaped plates 7 are fixedly connected by connecting bolts 9.

[0025] In this embodiment, the square tube steel column 1 is inserted into the base plate 4 and top plate 5 after passing through the steel column sliding hole 6. The I-beam 2 is inserted into the square tube steel column 1 after passing through the second connection port 8 and the first connection port 3. The four I-beams 2 are clamped by the hoisting device, and through their connection with the connecting device, the four I-beams 2 are kept as horizontal as possible to meet the construction requirements. The connecting bolts 9 are threaded into the square tube steel column 1 through the bolt holes set on the L-shaped plate 7.

[0026] The support device includes four support plates 10 that are evenly fixed at the bottom of the base plate 4. The support plates 10 and the bottom of the base plate 4 are fixedly connected by multiple support ribs 11. The square tube steel column 1 and the support plates 10 are fixedly connected by support bolts 12.

[0027] In this embodiment, after the connecting bolts 9 fix the square tube steel column 1 and the L-shaped plate 7, the support bolts 12 are threaded through the bolt holes provided on the support plate 10 and connected to the square tube steel column 1. The multiple support ribs 11 provide stronger support strength, making the position of the connecting device and the square tube steel column 1 more stable.

[0028] The hoisting device includes a cover plate 14, a hoisting plate 16, and hoisting bolts 17. A limit block 15 is fixedly installed at the bottom of the cover plate 14. The hoisting bolts 17 pass through the cover plate 14 and the limit block 15 and are threadedly connected to the hoisting plate 16. The limit block 15 and the hoisting plate 16 are matched with the inner hole of the square tube steel column 1. The four corners of the cover plate 14 are fixedly connected to the four corners of the top plate 5 by lifting bolts 13.

[0029] In this embodiment, after the limiting block 15 and the lifting plate 16 are placed on the top of the square tube steel column 1, the limiting block 15 and the lifting plate 16 are respectively located at the connection port 3. After the I-shaped beam 2 is inserted into the connection port 3, the limiting block 15 and the lifting plate 16 are respectively located on the upper and lower sides of the I-shaped beam 2.

[0030] By rotating the lifting bolt 17, the lifting plate 16 can be moved upward along the inner hole of the square tube steel column 1, so that the limiting block 15 and the lifting plate 16 clamp the I-shaped beam 2. By rotating the lifting bolt 13, the height of the connecting device can be adjusted to keep the I-shaped beam 2 as horizontal as possible, meeting the construction requirements. Preferably, the lifting bolt 17 and the lifting bolt 13 are operated alternately to ensure that the limiting block 15 and the lifting plate 16 clamp the I-shaped beam 2 and keep the I-shaped beam 2 as horizontal as possible.

[0031] Preferably, after the L-shaped plate 7 and the supporting upright plate 10 are fixedly connected to the square tube steel column 1 by connecting bolts 9 and supporting bolts 12 respectively, the I-shaped beam 2 can be welded to the bottom plate 4, the top plate 5, and the L-shaped plate 7 to increase the connection strength. During disassembly, it is only necessary to grind the welded part smooth.
