[0002] The vertical support structure of large equipment such as boilers often needs to be arranged and installed using a through-beam structure to adapt to the direction of equipment pipelines or the requirements of personnel passage. Figure 4-6 The node plates 10 are arranged in a dispersed manner. The node plates 10 are respectively fixed on both sides of the flange of the beam, and a plurality of stiffening ribs 9 in the beam are used to connect the node plates and the beam to transmit the axial force. The node plates 10 at the upper and lower flanges of the vertical support structure and the beam structure are connected by angle steels 8. This design not only has complex connection structure, high manufacturing cost, large space occupation, and affects equipment layout and personnel passage, but also when the axial force is large, the poor axial force transmission path will reduce the structural force efficiency. Summary of the invention

[0003] The present invention is to solve the above-mentioned problem and further provides a beam-penetrating device for a large axial force vertical support structure.

[0004] The technical solution adopted by the present invention to solve the above technical problems is:

[0005] A beam-penetrating device for a large axial force vertical support structure comprises a beam and a vertical support structure, wherein the beam comprises a web and a wing plate, the end of the vertical support structure close to the beam is an I-beam structure, and further comprises four beam-internal stiffening ribs, a node plate, eight node plate ribs and a first connecting clamp plate, wherein the node plate penetrates the web plate and is fixedly inserted into the beam and is arranged along the length direction of the vertical support structure, wherein the four beam-internal stiffening ribs are fixedly connected to the two side surfaces of the node plate in groups of two, and both ends of each beam-internal stiffening rib are fixedly connected to the wing plate, wherein the node plate ribs are welded to the node plate and a node plate rib is arranged in each extension line direction of each beam-internal stiffening rib, and the vertical support structure is fixedly connected to the node plate ribs via the first connecting clamp plate.

[0006] Furthermore, the first connecting clamping plate includes a first clamping plate and a second clamping plate, and each wing plate of the vertical support structure is correspondingly butted with two node plate ribs on the same side thereof, and is clamped and fixed respectively by the first clamping plate and the second clamping plate which are arranged oppositely.

[0007] Furthermore, the end of the node plate rib is welded to the wing plate.

[0008] Furthermore, the stiffening ribs and the node plates in the beam are arranged in the same direction.

[0009] Furthermore, a node plate through hole is formed on the web, and the node plate is inserted into the node plate through hole.

[0010] Furthermore, the node plate through hole is arranged conformally to the node plate located inside the node plate through hole.

[0011] Furthermore, the surfaces of the node plate in contact with the beam are fixed by welding.

[0012] Furthermore, the angle between the node plate and the beam ranges from 30° to 60°.

[0013] Furthermore, both ends of the node plate are respectively connected to the ends of the vertical support structure through second connecting clamping plates.

[0014] Compared with the prior art, the present invention has the following effects:

[0015] By setting a whole node plate in the beam to replace the traditional dispersed multiple node plate design, the size of the node plate is reduced. By setting the node plate, the stiffening rib plate in the beam and the node plate rib plate along the inclined direction of the vertical support structure, the transmission path of the axial force is optimized, the force transmission is made more direct, and the force efficiency and stability of the structure are improved. At the same time, the connection structure between the node plate rib plate and the vertical support structure is simple, which reduces the complexity of installation.

[0016] The stability of the node plate is enhanced by setting stiffening ribs inside the beam. Compared with the traditional design, the number of stiffening ribs is reduced, which reduces the complexity of processing and installation. The compact design releases more space, which is convenient for the layout of equipment pipelines and the passage of maintenance personnel. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] See attached Figure 1-3 To illustrate this embodiment, a beam-penetrating device for a large axial force vertical support structure includes a beam 1 and a vertical support structure 6, wherein the beam 1 includes a web 1-1 and a wing plate 1-2, and the end of the vertical support structure 6 close to the beam 1 is an I-beam structure, and also includes four beam-internal stiffening ribs 2, a node plate 3, eight node plate ribs 4 and a first connecting clamp 5, wherein the node plate 3 penetrates the web 1-1 and is fixedly inserted into the beam 1 and is arranged along the length direction of the vertical support structure 6, the four beam-internal stiffening ribs 2 are fixedly connected to the two side surfaces of the node plate 3 in groups of two, and both ends of each beam-internal stiffening rib 2 are fixedly connected to the wing plate 1-2, the node plate rib 4 is welded to the node plate 3 and a node plate rib 4 is arranged in each extension line direction of each beam-internal stiffening rib 2, and the vertical support structure 6 is fixedly connected to the node plate rib 4 through the first connecting clamp 5.

[0028] Compared with the traditional design of multiple node plates arranged in a dispersed manner, the node plate 3 arranged in the beam 1 of the present invention is an integral design, which greatly reduces the size of the node plate 3, not only improving the force efficiency and stability of the overall structure, but also simplifying the connection method between the beam 1 and the node plate 3, reducing the complexity of processing and installation; connecting the node plate rib 4 and the vertical support structure 6 through the first connecting clamp 5 can reduce the use of bolts and reduce the cost of use. The node plate, the stiffening rib plate in the beam and the node plate rib plate are arranged along the inclined direction of the vertical support structure to optimize the transmission path of the axial force, make the force transmission more direct, and improve the force efficiency and stability of the structure. Compared with the traditional design, the number of stiffening ribs is reduced, the complexity of processing and installation is reduced, and more space is released through the compact design, which is convenient for the layout of equipment pipelines and the passage of maintenance personnel.

[0029] The first connecting clamp plate 5 includes a first clamp plate and a second clamp plate.

[0030] The end of the node plate rib 4 is welded to the wing plate 1 - 2. By welding the end of the node plate rib 4 to the wing plate 1 - 2, the connection stability between the node plate 3 and the beam 1 is further improved.

[0031] The arrangement direction of the stiffening rib plate 2 in the beam is the same as that of the node plate 3. By setting the stiffening rib plate 2 in the beam and the node plate 3 at the same inclination angle, the transmission path of the axial force is optimized, thereby improving the force efficiency and stability of the overall structure.

[0032] The web 1-1 is provided with a node plate through hole, and the node plate 3 is inserted into the node plate through hole 1-3. By providing the node plate through hole, the node plate rib can be fixed on two sides of the node plate, optimizing the transmission path of the axial force and making the force transmission more direct.

[0033] The node plate through holes 1-3 are arranged in accordance with the node plate 3 located therein, thereby ensuring that there is no gap between the node plate and the web plate and the wing plate, facilitating the fixing of the node plate and the beam, and improving the stability of the connection between the node plate and the beam.

[0034] The surfaces of the node plate 3 that are in contact with the beam 1 are fixed by welding.

[0035] The angle between the node plate 3 and the beam 1 is in the range of 30° to 60°. The angle range of 30° to 60° can optimize the transmission path of the axial force and improve the force efficiency and stability of the overall structure.
