Description

Technical Field

[0001] This utility model relates to the field of steel structure installation technology, specifically a reinforcement component for steel structure connection nodes. 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, and employs rust removal and prevention processes such as silanization, pure manganese phosphating, water washing and drying, and galvanizing. The components are typically connected by welds, bolts, or rivets. However, during the use of steel structure buildings, the load may increase due to factors such as adding floors or changing the purpose of the structure. This may cause the original connection nodes to be unable to withstand the additional pressure, requiring reinforcement of the nodes to improve the structure's load-bearing capacity and ensure the safe use of the building. Existing reinforcement components usually add support members at the bottom. However, during installation, the reinforcement components can only fit against the bottom of the structure. The reinforcement components only provide support after the structure is subjected to a large load, causing the original connection nodes to bear greater forces, making them prone to deformation and affecting the stability of the structure. Utility Model Content

[0003] To address the aforementioned shortcomings, this utility model provides a reinforcing component for steel structure connection nodes, which effectively supports the structure and ensures the stability of the overall structure.

[0004] To achieve the above objectives, the present invention provides a reinforcing component for a steel structure connection node, comprising a first fixed seat and a second fixed seat. The first fixed seat is positioned directly above the second fixed seat. A hanging rod is vertically mounted on the surface of the first fixed seat. Multiple hanging rods are symmetrically arranged. A first slider is slidably connected to the top of the second fixed seat. A second slider is mounted on the top of the first slider. The top of the first slider and the bottom of the second slider are both sloped. The bottom end of the hanging rod passes through both sides of the second slider. A first fixing nut is threadedly connected to the surface of the hanging rod and located at the bottom of the second slider. First limiting tooth grooves are provided on both sides of the first fixed seat. Second limiting tooth grooves are provided on both sides of the second fixed seat. A limiting tooth block is provided on one side of the first and second limiting tooth grooves. The limiting tooth block restricts the sliding of the first slider on the top of the second fixed seat. The bottom end of the hanging rod passes through the limiting tooth block and is threadedly connected to the second fixing nut.

[0005] Preferably, it also includes a column and a crossbeam, one end of which is fixed to one side of the column by bolts, and the first fixing seat and the second fixing seat are fixed to one side of the column. The first fixing seat is located above the crossbeam, and the second fixing seat is located below the crossbeam.

[0006] Preferably, the top of the second slider contacts the bottom of the crossbeam.

[0007] Preferably, the top of the second fixed base is provided with a sliding groove, and the bottom of the first slider is fixedly connected to a slider that is slidably connected to the sliding groove.

[0008] Preferably, the boom includes a limiting block, a first boom, and a second boom arranged coaxially. The diameter of the second boom is smaller than the diameter of the first boom. The second boom is fixed to the bottom end of the first boom. The surface of the first boom is provided with a first threaded section that is adapted to a first fixing nut. The surface of the second boom is provided with a second threaded section that is adapted to a second fixing nut.

[0009] Preferably, the surface of the limiting tooth block is provided with a through hole that is adapted to the lifting rod.

[0010] The present invention adopts the above-mentioned technical solution, and its beneficial effects include: the reinforcing component of this steel structure connection node is reinforced by setting fixed seats at both the top and bottom of the node. The fixed seat at the top reinforces the crossbeam through a hanger and a second slider, ensuring that the second slider plays a supporting role during installation. At the same time, a sliding first slider is set on the fixed seat at the bottom. Since the opposite sides of the two sliders are both set as inclined surfaces, the movement of the first slider can support the second slider, thereby improving the load-bearing capacity of the entire crossbeam. The limiting tooth block that restricts the sliding of the first slider ensures the supporting effect of the first slider on the second slider, thus achieving effective support for the steel structure connection node.

Detailed Implementation

[0016] The present invention will be further described below with reference to the accompanying drawings.

[0017] Example 1: Please refer to Figure 1-4 This utility model provides a technical solution: a reinforcing component for a steel structure connection node, including a first fixing seat 1 and a second fixing seat 2. The first fixing seat 1 and the second fixing seat 2 have an L-shaped cross section and are provided with reinforcing ribs. The first fixing seat 1 is located directly above the second fixing seat 2. It also includes a column 11 and a crossbeam 12. One end of the crossbeam 12 is fixed to one side of the column 11 by bolts. The first fixing seat 1 and the second fixing seat 2 are fixed to one side of the column 11. The first fixing seat 1 is located above the crossbeam 12, and the second fixing seat 2 is located below the crossbeam 12. The first fixing seat 1 and the second fixing seat 2 are fixed to the column 11 by bolts.

[0018] A hanging rod 3 is vertically arranged on the surface of the first fixed base 1. Multiple hanging rods 3 are arranged symmetrically. In this embodiment, four hanging rods 3 are arranged. A first slider 4 is slidably connected to the top of the second fixed base 2. A second slider 5 is arranged on the top of the first slider 4. The top of the first slider 4 and the bottom of the second slider 5 are both set as inclined surfaces with an inclination angle of 10-20°. The relative sliding between the first slider 4 and the second slider 5 will increase the overall height through the inclined surfaces.

[0019] The top of the second slider 5 contacts the bottom of the crossbeam 12, the bottom end of the hanger 3 passes through both sides of the second slider 5, and the surface of the hanger 3 and the bottom of the second slider 5 are threaded with the first fixing nut 6. By tightening the first fixing nut 6, the crossbeam 12 is supported by the second slider 5.

[0020] The first fixed base 1 has first limiting tooth grooves 7 on both sides, and the second fixed base 2 has second limiting tooth grooves 8 on both sides. A limiting tooth block 9 is provided on one side of each of the first and second limiting tooth grooves 7 and 8. The limiting tooth block 9 restricts the sliding of the first slider 4 on the top of the second fixed base 2. By setting different widths of the tooth grooves, the overall height adjustment accuracy can be adjusted. In this embodiment, the tooth groove width is 2-5mm. When the inclination angle of the inclined plane is 10° and the tooth groove width is 5mm, the first slider 4 slides one tooth groove width, i.e., 5mm. The height increase between the first slider 4 and the second slider 5 is h = 5 × tan(10°) ≈ 5 * 0.1763 = 0.8815mm. Therefore, by controlling the inclination angle of the inclined plane and the width of the tooth groove, the height adjustment accuracy can be achieved.

[0021] The surface of the limiting tooth block 9 is provided with a through hole that matches the lifting rod 3. The bottom end of the lifting rod 3 passes through the limiting tooth block 9 and is threadedly connected to the second fixing nut 10, which realizes the fixing of the limiting tooth block 9 and prevents the limiting tooth block 9 from falling off.

[0022] The top of the second fixed base 2 is provided with a sliding groove, and the bottom of the first slider 4 is fixedly connected to a slider that slides in a sliding connection with the sliding groove, which ensures the stability of the first slider 4 and avoids lateral sliding.

[0023] The lifting rod 3 includes a coaxially arranged limiting block 31, a first rod body 32, and a second rod body 33. The diameter of the second rod body 33 is smaller than the diameter of the first rod body 32. The second rod body 33 is fixed to the bottom end of the first rod body 32. The surface of the first rod body 32 is provided with a first threaded section 34 that is adapted to the first fixing nut 6. The surface of the second rod body 33 is provided with a second threaded section 35 that is adapted to the second fixing nut 10. The design that the diameter of the second rod body 33 is smaller than the diameter of the first rod body 32 facilitates the quick threaded connection between the first fixing nut 6 and the first threaded section 34, thereby improving the installation efficiency.

[0024] During installation, the first fixing seat 1 and the second fixing seat 2 are fixed to the column 11 with bolts. The first fixing seat 1 is positioned above the crossbeam 12, and the second fixing seat 2 is positioned below the crossbeam 12. The first slider 4 is installed on the top of the second fixing seat 2, and the second slider 5 is installed on the top of the first slider 4. The hanger 3 is installed on the top of the first fixing seat 1 and passes through the second slider 5. The second slider 5 is fixed with the first fixing nut 6. The installation torque of the first fixing nut 6 is 150-300 N·m. Then, the first slider 4 is pushed from one side of the column 11 so that the first slider 4 is close to the bottom of the second slider 5. Then, the limiting tooth block 9 passes through the hanger 3 from the bottom so that the limiting tooth block 9 is connected with the first limiting tooth groove 7 and the second limiting tooth groove 8. The limiting tooth block 9 is fixed with the second fixing nut 10. To prevent the second fixing nut 10 from loosening, screw glue can be applied to the surface of the second threaded section 35.
