Description

Technical Field

[0001] This utility model belongs to the field of steel structure technology, and in particular relates to a connection node for steel structure mounting ear plate and horizontal stiffener. Background Technology

[0002] Mounting lugs are plate-shaped structural components made of metal or other high-strength materials, typically used between steel beams and steel columns. Their main structure includes a main plate and connecting parts, and their shapes can vary. In use, mounting lugs are mostly arranged in a cross shape and fixed to the surface of the steel column. By connecting the lugs, the structural beam is fixed to the surface of the steel column. Horizontal stiffening plates are reinforcing plates set horizontally in the steel beams and steel columns.

[0003] Currently, steel beams and columns are typically connected using bolts and mounting lugs or horizontal stiffeners. However, when connecting steel beams and columns, there may be overlaps between the mounting lugs and horizontal stiffeners. This necessitates cutting and removing the mounting lugs or horizontal stiffeners, resulting in material waste. Therefore, we need to design a connection node for steel structure mounting lugs and horizontal stiffeners. This connection structure provides a reliable connection point, avoiding the need for users to cut and remove the mounting lugs or horizontal stiffeners, reducing material waste, ensuring that the connection between the steel beams and other components is not damaged, and maintaining the integrity of the steel beams and columns.

It has the advantages of connecting the mounting ear plates and horizontal stiffeners through a connection structure, providing a reliable connection point, avoiding the need for users to cut and remove the mounting ear plates or horizontal stiffeners, reducing material waste, ensuring that the connection between the steel structure beam and other components is not damaged, and maintaining the integrity of the steel structure beam and steel structure column, thereby solving the above-mentioned technical problems.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A connection node for steel structure mounting ear plates and horizontal stiffeners includes four symmetrical mounting ear plates fixedly connected to the surface of a steel structure column. Four steel structure beams are fixedly connected to the surface of the steel structure column. Multiple bolts are provided through the surface of the steel structure column. Four stiffeners are fixedly connected to the top and bottom of the four steel structure beams. The opposite sides of the four stiffeners are fixedly connected to the steel structure column by bolts. Multiple horizontal stiffeners are fixedly connected to both sides of the steel structure beams. One side of the horizontal stiffener is in contact with the mounting ear plates. Angle steel is provided on both sides of the steel structure beams. Two angle steels are fixedly connected to the mounting ear plates and the steel structure beams by bolts. Four fixing plates are provided on the surface of the steel structure column. The upper and lower sides of the fixing plates are fixedly connected to the steel structure column by bolts. Connecting rods are fixedly connected to the opposite sides of the four mounting brackets. An upper top plate is fixedly connected to the end of the connecting rod away from the fixing plate. The upper top plate is fixedly connected to the steel structure beam by bolts.

[0006] Preferably, the steel structure beam has square grooves on both sides for two mounting lugs to pass through.

[0007] Preferably, a connecting plate is provided on the side of the horizontal stiffening plate away from the steel structure column. The two sides of the connecting plate are tightly fitted with the horizontal stiffening plate and the angle steel. The other side of the horizontal stiffening plate, the connecting plate and the angle steel are fixedly connected to the steel structure column by bolts.

[0008] Preferably, the reinforcement member is fixedly connected to side triangular baffles on both the left and right sides.

[0009] Preferably, four mounting brackets are fixedly connected to the top of the four steel structural beams and the surface of the steel structural columns. A sliding rod is rotatably connected to the inner cavity of each mounting bracket. A connecting sleeve is slidably connected to the other end of the sliding rod. An installation rod is slidably connected to the end of the connecting sleeve away from the sliding rod. The other end of the installation rod is rotatably connected to the inner cavity of the mounting bracket on the surface of the steel structural column.

[0010] Preferably, the surfaces of the plurality of bolts are threaded with nuts, and the surfaces of the mounting lugs and the steel structure beams are provided with circular holes for the bolts to pass through.

[0011] The beneficial effects of this utility model are:

[0012] 1. This utility model utilizes the combined use of horizontal stiffening plates, connecting plates, and angle steel to ensure that mounting ear plates are fixedly installed between steel structure columns and steel structure beams. This prevents the mounting ear plates and horizontal stiffening plates from overlapping and ensures good stability. Furthermore, the combined use of bolts, connecting rods, and a top plate enhances the stability between the steel structure columns and beams. This allows for reliable connection between the mounting ear plates and horizontal stiffening plates via a connecting structure, avoiding the need for users to cut or remove the mounting ear plates or horizontal stiffening plates, reducing material waste, and ensuring that the connection between the steel structure beams and other components is not damaged, thus maintaining the integrity of the steel structure beams and columns.

[0013] 2. The square groove of this utility model prevents the mounting ear plate from overlapping with the horizontal stiffening plate when it extends through both sides of the steel structure beam, ensuring the tightness of the connection between the mounting ear plate and the horizontal stiffening plate and improving the stability of the mounting ear plate and the horizontal stiffening plate when installed between the steel structure column and the steel structure beam.

[0014] 3. The connection plate in this utility model guides the connection between the horizontal stiffening plate and the angle steel, ensuring that there are no gaps when the horizontal stiffening plate and the angle steel are connected, thus improving the stability of the connection between the horizontal stiffening plate and the angle steel.

[0015] 4. By setting the side triangular baffle, this utility model enables the reinforcement to be fixed when the steel structure column and steel structure beam are connected. The side triangular baffle stabilizes the reinforcement and avoids the reinforcement from being unstable in supporting the steel structure column and steel structure beam, thus improving the stability of the reinforcement when connecting the steel structure column and steel structure beam.

Detailed Implementation

[0025] In the following description, embodiments of the steel structure mounting lugs and horizontally reinforced connection nodes of this utility model will be described with reference to the accompanying drawings.

[0026] Figure 1-6This invention illustrates a connection node between steel structure mounting lugs and horizontal stiffeners according to an embodiment of the present invention. It includes four symmetrical mounting lugs 2 fixedly connected to the surface of a steel structure column 1. Four steel structure beams 3 are fixedly connected to the surface of the steel structure column 1. Multiple bolts 4 penetrate the surface of the steel structure column 1. Four stiffeners 5 are fixedly connected to the top and bottom of each of the four steel structure beams 3. Side triangular baffles 10 are fixedly connected to both sides of each stiffener 5. The side triangular baffles 10 ensure that the stiffeners 5 are fixedly connected to the steel structure column 1 and steel structure beams 3 during connection, thus preventing instability in the support of the stiffeners to the steel structure column 1 and steel structure beams 3. To improve the stability of the connection between the four reinforcement components 5 and the steel structure column 1 and steel structure beam 3, the four reinforcement components 5 are fixedly connected to the steel structure column 1 on one side facing each other by bolts 4. Multiple horizontal stiffening plates 6 are fixedly connected to both sides of the steel structure beam 3. Square grooves 7 are provided on both sides of the steel structure beam 3 for two mounting ear plates 2 to pass through. The square grooves 7 prevent the mounting ear plates 2 from overlapping with the horizontal stiffening plates 6 when they pass through to both sides of the steel structure beam 3, ensuring the tightness of the connection between the mounting ear plates 2 and the horizontal stiffening plates 6, and improving the stability of the mounting ear plates 2 and the horizontal stiffening plates 6 between the steel structure column 1 and the steel structure beam 3. One side of the horizontal stiffening plate 6 contacts the mounting ear plate 2. Angle steel 9 is provided on both sides of the steel structure beam 3. Two angle steels 9 are fixedly connected to the mounting ear plate 2 and the steel structure beam 3 by bolts 4. A connecting plate 8 is provided on the side of the horizontal stiffening plate 6 away from the steel structure column 1. The two sides of the connecting plate 8 are tightly fitted to the horizontal stiffening plate 6 and the angle steels 9. The other side of the horizontal stiffening plate 6, the connecting plate 8, and the angle steels 9 are fixedly connected to the steel structure column 1 by bolts 4. The connecting plate 8 guides the connection between the horizontal stiffening plate 6 and the angle steels 9, ensuring no gaps during connection and improving the stability of the connection. Four fixing plates 11 are provided on the surface of the steel structure column 1. The upper and lower sides of the fixing plates 11 are fixedly connected to the steel structure column 1 by bolts 4. Each mounting bracket 14 has a connecting rod 12 fixedly connected to one side of each mounting bracket. The end of the connecting rod 12 away from the fixing plate 11 is fixedly connected to the top plate 13. The top plate 13 is fixedly connected to the steel structure beam 3 by bolts 4. Four mounting brackets 14 are fixedly connected to the top of the four steel structure beams 3 and the surface of the steel structure column 1. The inner cavity of the mounting bracket 14 is rotatably connected to the sliding rod 15. The other end of the sliding rod 15 is slidably connected to the connecting sleeve 16. The end of the connecting sleeve 16 away from the sliding rod 15 is slidably connected to the mounting rod 17. The other end of the mounting rod 17 is rotatably connected to the inner cavity of the mounting bracket 14 on the surface of the steel structure column 1. Nuts 18 are threadedly connected to the surfaces of multiple bolts 4. The surfaces of the mounting ear plate 2 and the steel structure beam 3 are provided with round holes for the bolts 4 to pass through.

[0027] Working Principle: In use, the user first fixes the steel structure beam 3 to the surface of the steel structure column 1. The mounting ear plates 2 are arranged in a cross shape on the surface of the steel structure column 1, with the steel structure beam 3 sandwiched between the two mounting ear plates 2. Due to the square groove 7, the mounting ear plates 2 do not jam during penetration. Then, the reinforcing member 5 is fixedly welded to the top and bottom of the steel structure beam 3. Next, the user uses bolts 4 to fix the reinforcing member 5 to the steel structure column 1. Then, the horizontal stiffening plates 6 fixedly connected to both sides of the steel structure beam 3 are connected to the mounting ear plates 2. Next, a connecting plate 8 is placed on one side of the horizontal stiffening plate 6, so that the angle steel 9 is installed between the horizontal stiffening plate 6 and the mounting ear plates 2. Finally, two bolts 4 are inserted through the steel structure column 1, the horizontal stiffening plate 6, the connecting plate 8, and the angle steel. Between 9, it is firmly secured together with the steel structure column 1, horizontal stiffening plate 6, connecting plate 8 and angle steel 9. Then, the nut 18 is rotated on the surface of the bolt 4 so that the bolt 4 will not detach from the steel structure column 1, horizontal stiffening plate 6, connecting plate 8 and angle steel 9. Then, the bolt 4 is inserted between the angle steel 9, mounting ear plate 2 and steel structure beam 3. The nut 18 is tightened on the bolt 4 to secure the angle steel 9, mounting ear plate 2 and steel structure beam 3 together. Then, the diameter of the bolt 4 on the fixing plate 11 and the top plate 13 ensures that the connecting rod 12 will not loosen when supported. Then, the top of the steel structure beam 3 and the steel structure column 1 are connected by the sliding rod 15, the mounting rod 17 and the connecting sleeve 16. Finally, when the mounting ear plate 2 and the horizontal stiffening plate 6 are connected between the steel structure column 1 and the steel structure beam 3, there is no overlap and the stability is strong.

[0028] In summary, the connection node between the steel structure mounting lugs and the horizontal stiffeners, through the combined use of the horizontal stiffener plate 6, the connecting plate 8, and the angle steel 9, ensures that the mounting lugs 2 and 6 are fixedly installed between the steel structure column 1 and the steel structure beam 3. This prevents the mounting lugs 2 and the horizontal stiffener plate 6 from overlapping and ensures good stability. Furthermore, the combined use of bolts 4, connecting rods 12, and the top plate 13 enhances the stability between the steel structure column 1 and the steel structure beam 3. This allows for a reliable connection between the mounting lugs and the horizontal stiffeners, avoiding the need for users to cut or remove the mounting lugs or horizontal stiffeners, reducing material waste, and ensuring that the connection between the steel structure beam and other components is not damaged, thus maintaining the integrity of the steel structure beam and column.
