[0001] The present invention relates to the field of steel structure buildings, in particular to a connection node between a steel structure corridor and a span ladder support roof. Background Art

[0002] The gap between the steel corridor and the roof panel of the ladder support leads to the exposed portion above the interface between the steel corridor and the ladder support. Existing technologies typically use upper wall panels welded together or bolted together, resulting in non-removable joints and poor reusability. This connection structure also suffers from insufficient rigidity, susceptibility to temperature deformation leading to leakage, and inconvenient maintenance. It is difficult to adapt to the dynamic load requirements of complex terrain or industrial scenarios. An innovative connection solution that balances stability, removability, and durability is urgently needed. Summary of the Invention

The support roof panel 2 is higher than the corridor roof panel 1. The support roof panel 2 is installed on the support top frame, and the four corners of the support top frame are connected to the support columns 3.

[0020] An upper wall purlin 5 is arranged parallel to the outer side of the bracket top frame end beam 4. A first horizontal plate 7 is vertically connected to the middle part of the outer side of the bracket top frame end beam 4, and the outer bottom of the first horizontal plate 7 is detachably connected to the upper wall purlin 5. Specifically, the bracket top frame end beam 4 adopts an I-beam, and a first stiffening plate 8 is provided between the inner side of the web of the I-beam and the upper and lower wing plates, a second stiffening plate 9 is provided between the outer side of the web of the I-beam and the lower wing plate and the first horizontal plate 7, and a third stiffening plate 10 is provided between the outer side of the web of the I-beam and the upper wing plate and the first horizontal plate 7 to enhance the local stiffness and bearing capacity of the end beam. A first bolt hole 11 is provided at the corresponding position of the first horizontal plate 7 and the upper wall purlin 5. There are 4 first bolt holes 11, which are respectively provided on both sides of the third stiffening plate 10. The node disassembly and construction efficiency are improved through bolt connection.

[0021] A lower wall purlin 6 is provided below the upper wall purlin 5. The upper wall purlin 5 and the lower wall purlin 6 are connected in the middle by a support rod 12 and at the ends by an edge banding purlin 13. In this embodiment, there are three support rods 12, which are respectively provided at the ridge position of the corridor roof panel 1 and the middle of the sloped roof of the corridor roof panel 1. Specifically, Figure 2 、 Figure 4 As shown in the diagram of the connection between brace 12 and the ridge of the corridor roof panel 1, the upper and lower purlins 5 and 6 have a downward-facing C-shaped cross-section, while the brace 12 has an L-shaped cross-section. An upper connecting plate 14 is vertically welded to the interior of the upper purlin 5, while a lower connecting plate 15 is vertically welded to the exterior of the lower purlin 6. The upper side of the brace 12 is welded to the upper connecting plate 14, while the lower side of the brace 12 is welded to the lower connecting plate 15. This strengthens the force transmission path between the purlins, reduces the risk of deformation, and ensures the overall stability of the structure.

Second bolt holes 17 are provided at positions corresponding to the second horizontal plate 16 and the upper wall purlin 5 or the lower wall purlin 6. A fourth stiffening plate 14 is provided between the outer side of the I-beam column web and the second horizontal plate 16. The number of second bolt holes 17 is 4, which are respectively arranged on both sides of the fourth stiffening plate 14.

[0023] like Figure 1 、 Figure 6 As shown, the edge purlin 13 has an L-shaped cross-section, with one inner side contacting the end faces of the adjacent upper and lower purlins 5 and 6, and the other inner side contacting the outer sides of the adjacent upper and lower purlins 5 and 6. This provides a simple structure and a reliable connection. Reinforcement plates 19 are provided at the bottom of each end of the upper and lower purlins 5 and 6 to increase the bending strength of the purlin ends.

[0024] The arrangement of upper and lower purlins 5 and 6 at the connection point between the steel structure corridor and the over-span ladder support roof provides strong support for the installation of the upper wall panels. The connection between the upper wall panels and the upper and lower purlins 5 and 6 is conventional. To prevent rain leakage, a bent plate can be installed at the lower edge of the upper wall panels to overlap the corridor roof panel 1. This is also conventional and will not be described in detail here.
