[0027] To enable those skilled in the art of this technology to better understand the solution of this application, the following further detailed description of this application will be given in conjunction with the accompanying drawings and specific embodiments.
[0028] Please refer to Figure 1 , this embodiment provides an H-shaped steel direction-changing conversion node. This conversion node is generally applicable to two H-shaped steels, and the direction conversion of the two H-shaped steels is achieved through the conversion node. For example, when the upper and lower flange plates of the first H-shaped steel 1 are arranged horizontally, the corresponding second H-shaped steel 2 can be transitioned through this conversion node to a direction different from that of the first H-shaped steel 1, thereby realizing the direction change of the H-shaped steel.
[0029] Among them, the second H-shaped steel 2 is arranged at the end of the first flange plate 12 of the first H-shaped steel 1. Specifically, please refer to Figure 1 , the second web 21 of the second H-shaped steel 2 is fixedly connected to the first flange plate 12 of the first H-shaped steel 1 and maintains a certain connection strength; a strip component 3 for fixedly clamping the first flange plate 12 is provided on the second flange plate 22. The connection strength between the first H-shaped steel 1 and the second H-shaped steel 2 is further improved through the strip component 3. A stiffening rib 4 is arranged in the steel groove at one end of the first H-shaped steel 1 close to the second H-shaped steel 2. The periphery of the stiffening rib 4 is fixedly connected to the first web 11 and the first flange plate 12 of the first H-shaped steel 1, thereby improving the support strength of the first flange plate 12, and further avoiding deformation and other situations of the first flange plate 12 at the connection with the second H-shaped steel 2, and improving the connection stability of this node. At the same time, one side of the stiffening rib 4 facing the strip component 3 is fixedly connected to the strip component 3, which can further improve the connection strength between the first H-shaped steel 1 and the second H-shaped steel 2, so that the H-shaped steel obtains a relatively reliable connection effect through this node.
[0030] In summary of the above embodiments, this application realizes the turning transition of the first H-shaped steel 1 to the second H-shaped steel 2 by setting the strip component 3 and the stiffening rib 4. Specifically, the second web 21 of the second H-shaped steel 2 is fixedly connected to the end of the first flange plate 12 of the first H-shaped steel 1, and the plate surface of the second web 21 is in the same direction as the plate surface of the first flange plate 12, thereby realizing the direction conversion of the H-shaped steel, and improving the connection stability of the two H-shaped steels through the strip component 3 and the stiffening rib 4, so as to realize a reasonable transition of the H-shaped steel structure through a simple node, and further enabling the H-shaped steel to have a relatively high connection stability after the direction conversion, meeting the requirements of buildings or structures.
[0031] In addition, the plate surface of the second web 21 is parallel or coincident with the plate surface of the first flange plate 12, and at the same time, the abutting surfaces of the second web 21 and the first flange plate 12 are parallel, so that the abutting surfaces have sufficient contact area, and the fixed connection between the first H-shaped steel 1 and the second H-shaped steel 2 is realized by welding at the abutting position.
[0032] Considering that the second H-shaped steel 2 has two second flange plates 22, the strip assembly 3 can be symmetrically arranged at the ends of the two second flange plates 22. For specific reference, please refer to Figure 3 and Figure 4 . The symmetrically arranged strip assembly 3 can make the connection force between the second H-shaped steel 2 and the first H-shaped steel 1 more balanced through the strip assembly 3, thereby obtaining a relatively stable connection effect.
[0033] The strip assembly 3 includes strips arranged on both sides of the first flange plate 12. For specific reference, please refer to Figure 1 and Figure 2 . The two strips are respectively in contact with the two plate surfaces of the first flange plate 12 and are welded and fixed at the contact points, so as to ensure the connection strength between the strip assembly 3 and the second H-shaped steel 2 and the first H-shaped steel 1.
[0034] In addition, for a strip assembly 3, the two strips therein will form a rectangular parallelepiped outer contour with the same width and thickness corresponding to the second flange plate 22. For specific reference, please refer to Figure 5 . If the width and thickness of the flange plate respectively correspond to H2 and H3 in Figure 5 , then the strip assembly 3 will form a rectangular parallelepiped contour with the same width and thickness as the second flange plate 22, so as to minimize the influence of the strip assembly 3 on the external space while ensuring the connection strength of the strip assembly 3.
[0035] When the strip assembly 3 is connected to the second flange plate 22, their contact surfaces are arranged in parallel. That is to say, the strip assembly 3 can be regarded as an extension of the second flange plate 22, except that there is a gap in the middle of the strip assembly 3 to accommodate the first flange plate 12, and they are welded and fixed at the contact point between the strip assembly 3 and the second flange plate 22 to ensure their connection strength.
[0036] In some embodiments, the first side of the stiffening rib 4 is welded and fixed to the first web 11, and the second side of the stiffening rib 4 is welded and fixed to the first flange plate 12 to ensure the connection strength between the stiffening rib 4 and the first H-shaped steel 1; a notch is provided on the third side of the stiffening rib 4, and one of the strips in the strip assembly 3 can pass through the notch, and at the same time, the strip can be in contact with the inner wall of the notch and be welded and fixed at the contact point, so as to ensure the connection strength between the strip assembly 3 and the stiffening rib 4.
[0037] Since the H-shaped steel has two steel groove structures, and the first flange plate 12 corresponds to two grooves, the stiffening ribs 4 can be symmetrically arranged in the two steel grooves of the first H-shaped steel 1 to ensure the overall support strength of the first flange plate 12. At the same time, the third side of the stiffening rib 4 does not extend beyond the side of the first flange plate 12, so as to avoid the influence of the stiffening rib 4 on the external space.
[0038] For specific reference, please refer to Figure 4, the height of the second H-shaped steel 2 is less than or equal to the width of the first flange 12, and the height of the H-shaped steel is Figure 5 H1 in Figure 5 . Furthermore, the second H-shaped steel 2 can be arranged within the width range of the first flange 12. Specifically, in the height direction of the second H-shaped steel 2, it is within the width range of the first flange 12, so as to ensure the butting effect between the second web 21 and the first flange 12, and avoid parts that are partially suspended or not butted against the first flange 12 in the height direction of the second H-shaped steel 2.
[0039] In some embodiments, the height of the second H-shaped steel 2 can be the same as the width of the first flange 12, and the outer plate surfaces of the two second flanges 22 are respectively flush with the side edges of the two first flanges 12.
[0040] Similarly, please refer to Figure 4 , the thickness of the second web 21 is less than or equal to the thickness of the first flange 12, and the thickness of the web is Figure 5 H4 in Figure 5 . The second web 21 can be arranged within the thickness range of the first flange 12, so as to ensure the butting area between the second web 21 and the first flange 12, ensure the butting effect, and facilitate subsequent operations such as welding and fixing.
[0041] It should be noted that in this specification, relational terms such as first and second are only used to distinguish one entity from several other entities, and do not necessarily require or imply any actual relationship or order between these entities.
[0042] In this article, specific examples are used to elaborate on the principle and implementation manner of the present application. The description of the above embodiments is only used to help understand the method and its core idea of the present application. It should be pointed out that for those of ordinary skill in the art in this technical field, without departing from the principle of the present application, several improvements and modifications can be made to the present application, and these improvements and modifications also fall within the protection scope of the claims of the present application.
