Example 1
The present embodiment provides a rigid connection node, the structure of which is shown in fig. 2 and 3, comprising an i-beam 100, a rectangular steel pipe 200 and a stiffener 300.
Wherein the i-beam 100 comprises a flange plate 101 and a web 102. The rectangular steel pipe 200 is disposed at a side of the I-beam 100, and is provided with a receding portion 201 adapted to the flange plate 101. The stiffener 300 is disposed between the I-beam 100 and the rectangular steel pipe 200, and is connected to both the I-beam 100 and the rectangular steel pipe 200.
As shown in fig. 2 and 3, in the embodiment, a receding portion 201 adapted to the flange plate 101 is cut from the rectangular steel pipe 200, so that the local i-beam 100 is attached to the surface of the rectangular steel pipe 200, and has a suitable size, which is easy to process and weld, and at the same time, two stiffening ribs 300 are disposed at corresponding positions of the rectangular steel pipe 200 and welded, so that the structure of the node can effectively, safely and reliably transmit the internal force of the rectangular steel pipe 200, and the local stress concentration of the node steel pipe is removed, and the requirement of a rigid node is met. The problems that the I-shaped beam 100 and the rectangular steel pipe 200 are rigidly connected and are randomly arranged, construction is difficult, quality cannot be guaranteed and stress cannot be effectively transmitted in a common stiffening plate arrangement mode are solved.
The rigid connection node provided by the embodiment changes the traditional node connection mode by arranging the relief part 201 on the rectangular steel pipe 200 and arranging the stiffening rib 300 between the rectangular steel pipe 200 and the I-shaped beam 100, so that the internal force of the node out of the rod can be effectively transmitted, the purpose of a rigid area is achieved, and meanwhile, the rigid connection node conforms to the model assumption, the structural reliability is ensured, and the structural safety is improved.
Example 2
The present embodiment provides a rigid connection node comprising an I-beam 100, a rectangular steel tube 200 and stiffeners 300. Therein, the i-beam 100 comprises a flange plate 101 and a web 102. The rectangular steel pipe 200 is disposed at a side of the I-beam 100, and is provided with a receding portion 201 adapted to the flange plate 101. The stiffener 300 is disposed between the I-beam 100 and the rectangular steel pipe 200, and is connected to both the I-beam 100 and the rectangular steel pipe 200.
As shown in fig. 2 and 3, the positioning portion 201 is in contact with and connected to the inner side of the flange plate 101. Specifically, the letting portion 201 in this embodiment is a notch 201a formed by cutting off the wall plate 203 from the end of the rectangular steel pipe 200, the length of the notch 201a is equal to the extension length of the flange plate 101, and the depth of the notch 201a is the same as the thickness of the flange plate 101, so that the partial i-beam 100 is attached to the surface of the rectangular steel pipe 200, and the size of the partial i-beam is suitable for easy processing and welding.
As shown in fig. 2, the stiffener 300 of the present embodiment is disposed perpendicular to the web 102, and has two ends connected to the wall plate 203 of the rectangular steel pipe 200 and the lower wing plate 101b of the i-beam 100, respectively. Two parallel stiffening ribs 300 are arranged between each rectangular steel pipe 200 and the lower wing plate 101b, and the stiffening ribs 300 are flush with the outer sides of the side wall plates 203 of the rectangular steel pipe 200.
In order to ensure the stability of the connection, the positioning portion 201 and the flange plate 101 are connected by welding, and the stiffening rib 300 is connected by welding with the rectangular steel pipe 200 and the i-beam 100. Specifically, as shown in fig. 2 and 3, the contact position of the abdication part 201 of the rectangular steel pipe 200 and the flange plate 101, and the circle formed by the end of the rectangular steel pipe 200 and the web plate 102 are all welded. The three-side contact locations formed by the two ends of the stiffener 300 and the side in contact with the web 102 are also welded.
The position-giving part 201 arranged on the rectangular steel pipe 200 is also convenient for determining the position between the rectangular steel pipe 200 and the I-shaped beam 100 and welding construction. Two welded stiffening ribs 300 are arranged at the corresponding positions of the rectangular steel pipe 200, so that the internal force of the rectangular steel pipe 200 can be effectively, safely and reliably transmitted by the structure of the node, the local stress concentration of the node steel pipe is eliminated, and the requirement of a rigid node is met.
In order to further enhance the local stress condition of the rectangular steel pipe 200, as shown in fig. 3 and 4, a reinforcing stiffening plate 202 is disposed inside the abdicating portion 201 in this embodiment, and the reinforcing stiffening plate 202 is welded to the inner wall of the rectangular steel pipe 200 and aligned to the edge of the flange plate 101.
By additionally arranging the reinforcing stiffening plate 202 in the rectangular steel pipe 200, stress concentration possibly caused by contact between the rectangular steel pipe 200 and the stiffening ribs 300 and other positions is weakened, and meanwhile, the reinforcing method is a reinforcing measure for local stress of the rectangular steel pipe 200. As shown in fig. 5a, 5b, and 5c, the three diagrams respectively correspond to a stress cloud diagram of the stiffening plate arrangement mode of the conventional i-beam and the rectangular steel pipe in fig. 1a, a stress cloud diagram of the semi-rigid connection mode of the conventional i-beam and the rectangular steel pipe in fig. 1b, and a stress cloud diagram of the rigid connection joint in the connection mode of the embodiment in fig. 2. As can be seen from the stress cloud chart of fig. 5a, in the connection mode of fig. 1a, the flange plate 101 of the main structural member of the i-beam is greatly influenced by the connection of the rectangular steel pipes, and the phenomena of stress superposition, concentration and enlargement exist, because no stiffening plate 202 and no stiffening plate 300 are arranged, a part of stiffening plate is not easy to construct, the stiffening plate 300 in the node area of the rectangular steel pipe and the related range is greatly stressed, and the stress concentration range is large; as shown in fig. 5b, in the connection mode shown in fig. 1b, the flange plate 101 of the main structural member of the industrial beam is most affected by the connection of the rectangular steel pipes, the phenomena of stress superposition, concentration and enlargement are most obvious, although the flange plate is a semi-rigid connection node, the flange plate still needs to transmit corresponding internal forces such as bending moment, shearing force, axial force and the like, and meanwhile, because the stiffening plate 300 is not arranged, the web plate 102 of the main structural member of the industrial beam has the phenomena of stress concentration and enlargement in the node area and the related range of the rectangular steel pipes; in the connection mode of the invention shown in fig. 2, as the stiffening plates 300 and the stiffening plates 202 are arranged, and the construction operation mode is changed, the lower flanges 203 of the rectangular steel pipes can extend to the web plates 102 of the I-shaped beams conveniently, and finally, the influence of the flange plates 101 of the I-shaped beams at the nodes is reduced to the minimum, the web plates 102 of the I-shaped beams are basically not influenced by the connection nodes, and the overall stress level of the stiffening plates 300 and the relevant ranges of the connection node areas is also the minimum, so that the connection mode is the safest and the most reliable, and is beneficial to construction.
