Obviously, the described embodiment is a part of the embodiment of the utility model, not all the embodiments.

[0032] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0033] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0034] Railway station buildings need to be equipped with canopies that connect to the platform due to their passenger boarding and disembarking functions. Steel structure canopies are usually steel frame structures, including steel columns, steel beams, roof purlins, roof panels and other structures. The canopy has an architectural shape, and the slope of the roof panel must be no less than 5% to ensure smooth drainage and no water accumulation. The electromechanical pipelines of the canopy are passed through the web of the beam from the side of the beam along the track direction. The track direction is the extension direction of the slope of the curved slope roof on the horizontal plane. When encountering steel beams arranged along the vertical track direction, holes are opened at the web of the steel beam, and the electromechanical pipelines are all exposed. Usually the roof purlin system includes main purlins and additional purlins. The main and additional purlins of the roof are arranged vertically. The upper surface of the main purlin is flush with the upper flange of the steel beam along the track. The main purlin is welded to the web of the steel beam along the track. The additional purlin is welded on top of the main purlin. The slope and shape of the entire roof are adjusted by adjusting the different heights of the additional purlins. In addition to the main purlins to ensure the safety of the structure, additional purlins are also added, which greatly increases the amount of steel used in the canopy. In addition, since the side walls of the purlins are relatively thin, increasing the length and number of butt welds can easily lead to welding deformation.

[0035] Combine the following Figures 1 to 4 , describing an embodiment of the utility model.

[0036] According to an embodiment of the utility model, a beam and purlin connection structure is provided, comprising:

[0037] The crossbeam 1 comprises a plurality of crossbeams 1 and is spaced apart in the horizontal direction;

[0038] The purlin 3 is located above the crossbeam 1. The purlin 3 includes a plurality of purlins and is spaced apart along the slope direction of the sloping roof. The purlin 3 is extended perpendicular to the slope direction.

[0039] The connecting structure 2 includes multiple ones and is fixedly connected to the beam 1. At least part of the connecting structure 2 is located above the beam 1, and along the slope direction, the spacing between the top of the connecting structure 2 and the top of the beam 1 gradually decreases; the connecting structure 2 is correspondingly arranged at both ends of the purlin 3, so that one end of the purlin 3 is fixedly connected to the top area of ​​one connecting structure 2, and the other end is fixedly connected to the top area of ​​another connecting structure 2.

[0040] The crossbeam and purlin connection structure provided in this embodiment has a crossbeam 1 that supports and fixes the purlin 3 through a connection structure 2, and by gradually reducing the height of the top area of ​​the connection structure 2 along the slope direction, the height of the purlin 3 is adjusted to achieve the slope setting of the roof, avoiding the need to add additional purlins 8 and using additional purlins 8 of different height specifications to achieve the slope setting of the roof, which is beneficial to saving the amount of steel used in the building and achieving the effect of saving materials.

[0041] Specifically, Figure 1 The vertical track direction shown in the figure is defined as the slope direction perpendicular to the slope roof; Figure 3 and Figure 4 The along-track direction shown in is defined as the direction along the horizontal direction and perpendicular to the vertical track direction as the along-track direction. The crossbeam 1 is extended in the horizontal direction, and multiple crossbeams 1 are spaced apart in the vertical track direction, and the length direction of the crossbeam 1 is perpendicular to its distribution direction, that is, the length direction of multiple crossbeams 1 is parallel to the along-track direction. Multiple connecting structures 2 are fixedly connected to each crossbeam 1, and multiple connecting structures 2 are spaced apart along the length direction of the crossbeam 1, wherein the position of the connecting structure 2 on the crossbeam 1 corresponds to the position of the purlin 3, and each purlin 3 is fixedly connected to a connecting structure 2 at both ends, and some connecting structures 2 are fixedly connected to a purlin 3 on both sides along the length direction of the crossbeam 1. Along the length direction of the beam 1, the spacing between the top of the connecting structure 2 and the top of the beam 1 gradually decreases, and the purlin 3 is fixedly connected to the top area of ​​the connecting structure 2, so that the slope setting of the building roof can be achieved through the height change of the connecting structure 2, which saves the steel consumption of the purlin system, achieves the effect of saving materials, and reduces the welding amount of the butt welds of the main purlin 9 and the additional purlin 8, effectively avoiding structural deformation caused by welding deformation, which is conducive to improving construction efficiency and saving construction period.

[0042] In some embodiments, in combination Figures 1 to 4 As shown, a groove 4 is formed inside the connection structure 2 , and the groove 4 penetrates the connection structure 2 along the length direction of the crossbeam 1 , so as to allow the electromechanical pipeline 5 to pass through the groove 4 .

[0043] The beam and purlin connection structure provided in this embodiment allows the electromechanical pipelines 5 to pass through the grooves 4, thereby avoiding the electromechanical pipelines 5 from being arranged close to the web of the beam, which is beneficial for the pipelines not to be exposed and greatly improves the beauty and simplicity of the building.

[0044] Specifically, the minimum height of the groove 4 is greater than the height of the electromechanical pipeline 5 to be laid. After the purlin 3 is installed, the electromechanical pipeline 5 is laid in the groove 4. The groove 4 is located above the beam 1 so that the electromechanical pipeline 5 is routed along the top of the beam, which is beneficial to reduce the exposure of the pipeline and improve the beauty and simplicity of the building. After the electromechanical pipeline 5 is laid in place, the corrugated steel plate 6 is laid on the upper end surface of the purlin 3, and the corrugated steel plate 6 and the purlin 3 are fixed together by screws 7. In addition, a rubber pad is provided between the contact surface of the corrugated steel plate 6 and the screw 7 to seal the gap between the screw 7 and the corrugated steel plate 6 to achieve a waterproof effect.

[0045] In some embodiments, in combination Figures 1 to 4 As shown, the connection structure 2 includes two connection plates 22 spaced apart in the horizontal direction. The connection plates 22 are fixedly connected to the beam 1 and form the side walls of the channel 4. The purlin 3 is fixedly connected to the side of the connection plates 22 away from the channel 4.

[0046] Specifically, the connecting plate 22 is arranged along the gravity direction, and the plane where the connecting plate 22 is located is parallel to the length direction of the beam 1, wherein the connecting plate 22 can be fixedly connected to the top wall of the beam 1, or fixedly connected to the upper area of ​​the side wall of the beam 1. The area between the two connecting plates 22 and the area above the beam 1 partially overlap to form the groove 4.

[0047] In some embodiments, in combination Figures 1 to 4 As shown, along the width direction of the purlin 3 , the width of the connecting plate 22 is greater than the width of the purlin 3 .

[0048] The beam and purlin connection structure provided in this embodiment makes the width of the connection plate 22 greater than the width of the purlin 3, so as to ensure that the weld between the connection plate 22 and the purlin 3 is fully welded.

[0049] In some embodiments, in combination Figures 1 to 4 As shown, along the width direction of the purlin 3 , the edge of the connecting plate 22 is wider than the edge width of the purlin 3 by at least 5 mm.

[0050] Preferably, the upper end surface of the purlin 3 is flush with the upper end surface of the connecting plate 22, and both ends of the connecting plate 22 along the width direction extend beyond the edge of the purlin 3 by at least 5 mm, so as to ensure that the vertical fillet welds on both sides of the connecting plate 22 and the purlin 3 are fully welded.

[0051] In some embodiments, in combination Figures 1 to 4 As shown, the connection structure 2 further includes a fixing member 21 fixedly connected between the two connection plates 22 .

[0052] The crossbeam and purlin connection structure provided in this embodiment is fixedly connected to the two connection plates 22 at the same time through the fixing member 21 , so as to enhance the overall stability of the two connection plates 22 .

[0053] Specifically, the fixing member 21 is arranged at an angle to the connecting plate 22. As a preferred embodiment, the fixing member 21 extends in the horizontal direction. The fixing member 21 can be fixedly connected to the upper area of ​​the connecting plate 22, or fixedly connected to the middle area of ​​the connecting plate 22, thereby enhancing the overall stability of the fixed connection between the two connecting plates 22 and the crossbeam 1.

[0054] In some embodiments, in combination Figures 1 to 4 As shown, the fixing member 21 comprises a flat plate.

[0055] Specifically, the fixing member 21 includes a straight plate, a curved plate, a straight rod, a curved rod, etc. One end of the fixing member 21 is fixedly connected to one connecting plate 22 , and the other end is fixedly connected to another connecting plate 22 .

[0056] In some embodiments, in combination Figures 1 to 4 As shown, the connection structure 2 comprises U-shaped steel.

[0057] Specifically, the connecting structure 2 includes U-shaped steel, I-shaped steel, and box-shaped steel. Taking the U-shaped steel as an example, the opening of the U-shaped steel faces downward, and its two parallel flanges are respectively constructed as connecting plates 22 and fixedly connected to the beam 1. The web connecting the two flanges is constructed as a fixing part 21, and the hollow cavity area enclosed by the open side of the U-shaped steel and the beam 1 is constructed as a groove 4.

[0058] In some embodiments, in combination Figures 1 to 4 As shown, a plurality of purlins 3 are evenly distributed along the slope direction.

[0059] The beam and purlin connection structure provided in this embodiment is beneficial to enhancing the overall stability of the roof structure by evenly distributing multiple purlins 3.

[0060] Specifically, the intervals between two adjacent purlins 3 in the horizontal direction are the same, and the connection structures 2 are equidistantly distributed on the beam 1 corresponding to the positions of the purlins 3 , thereby improving the stability of the purlin system in supporting the corrugated steel plate 6 .

[0061] In some embodiments, in combination Figures 1 to 4 As shown, a plurality of beams 1 are distributed at equal intervals in the horizontal direction.
