Description

Technical Field

[0001] This utility model relates to the field of steel structure buildings, and in particular to a deformation joint node for gutters in steel structure buildings. Background Technology

[0002] Prefabricated steel structure buildings are widely used in practical engineering projects due to their advantages such as high strength, lightweight structure, and ease of installation and transportation. However, once a steel structure building reaches a certain length as specified in the regulations, expansion joints need to be designed in the roof and wall structures to prevent cracks or damage caused by changes in climate and temperature. Expansion joint covers are then installed to ensure waterproofing. Currently, roof gutters are typically connected to the expansion joint covers and gutters directly with rivets at the expansion joint junctions. Over time, this connection point is prone to water seepage, affecting the comfort of living inside the building. Utility Model Content

[0004] The purpose of this utility model is achieved as follows: A steel structure building gutter expansion joint node, wherein a pair of gutters are symmetrically arranged on both sides of the expansion joint. The gutter includes a base plate, side uprights arranged on both sides of the base plate, and an end upright at one end of the base plate. The base plate is provided with a drain outlet. The end upright is higher than the side uprights. The upper edge of the side upright has a lateral inclined flange facing outward of the gutter, and the inclination angle of the lateral inclined flange is consistent with that of the roof panel. The lower edge of the roof panel overlaps the lateral inclined flange. The upper edge of the end upright has an end horizontal flange facing inward of the gutter, and the top of the end horizontal flange is provided with a... The expansion joint cover has an upward protrusion at the top and an upward-sloping upper section at the end of the roof panel. The upper sloping section connects to a horizontal section, which in turn connects to an inverted U-shaped connecting section. The upper surface of the connecting section is attached to the lower surface of the horizontal flange. A U-shaped seepage-proof groove is glued and fixed to the outer side of the side panel, and the seepage-proof groove is inserted into the connecting section. The expansion joint cover, the horizontal flange, and the connecting section are connected by waterproof screws. The expansion joint cover has lower sloping edges on both sides with the same inclination angle as the upper sloping section, and the lower end of the lower sloping edge is lower than the upper end of the upper sloping section. This utility model of a steel structure building gutter expansion joint node improves the roof waterproofing effect through the structural design of the roof panel end and the seepage-proof groove, and has the advantages of convenient and reliable connection and strong structural stability.

[0005] As a further improvement of this utility model, the roof panel and the side-tilted flange are detachably connected, the lower surface of the side-tilted flange is provided with a supporting purlin, and an eaves drip plate is provided between the bottom edge of the roof panel and the side panel, which further improves the structural stability and waterproof effect.

[0006] As a further improvement of this utility model, the eaves drip plate includes an upper connecting part, a vertical part, and a lower sloping part facing the side upright plate. The upper connecting part is connected to the roof panel, the lower sloping part, and the side upright plate by waterproof adhesive, which is convenient to connect and can effectively guide rainwater into the gutter.

[0007] As a further improvement of this utility model, the height of the lower inclined edge is not less than 70mm to prevent rainwater from entering from the outside of the expansion joint cover.

Detailed Implementation

[0014] like Figure 1-3 The steel structure building shown has a gutter expansion joint node with a pair of gutters 1 symmetrically arranged on both sides of the expansion joint. Each gutter 1 includes a base plate 1A, side panels 1B on both sides of the base plate 1A, and an end panel 1C at one end of the base plate 1A. A drain outlet 2 is provided on the base plate 1A, and a drainage pipe is connected to the bottom of the drain outlet 2. The end panel 1C is higher than the side panels 1B. The upper edge of the side panels 1B has a lateral inclined flange 1D facing outwards from the gutter 1, with the inclination angle of the lateral inclined flange 1D matching that of the roof panel 3. The lower edge of the roof panel 3 overlaps the lateral inclined flange 1D. The upper edge of the end panel 1C has an end horizontal flange 1E facing inwards from the gutter 1. An expansion joint cover plate 4 is provided on the top of the end horizontal flange 1E.

[0015] The expansion joint cover plate 4 has an upward protrusion 4A at its top, and the roof panel 3 has an upwardly inclined upper slope 3A at its end. A horizontal section is connected to the end of the upper slope 3A, and an inverted U-shaped connecting part 3B is connected to the end of the horizontal section. The upper surface of the connecting part 3B is in contact with the lower surface of the end horizontal flange 1E. The expansion joint cover plate 4, the end horizontal flange 1E, and the connecting part 3B are connected by waterproof screws 6. The expansion joint cover plate 4 has lower slopes 4A on both sides with the same inclination angle as the upper slope 3A. The horizontal height of the lower end of the lower slope 4A is lower than the horizontal height of the upper end of the upper slope 3A. Specifically, in this embodiment, the height of the lower slope 4A is not less than 70mm to prevent rainwater from entering from the outside of the expansion joint cover plate 4.

[0016] A U-shaped waterproof groove 5 is attached and fixed to the outside of the side panel 1B. The waterproof groove 5 is inserted into the connecting part 3B. Specifically, the vertical edge of the inverted U-shaped connecting part 3B of the roof panel 3 near the side panel 1B is inserted into the waterproof groove 5, and the vertical edge of the waterproof groove 5 away from the side panel 1B is inserted into the connecting part 3B. Therefore, even if leakage occurs at the connection point of the waterproof screw 6, rainwater can only fall into the waterproof groove 5 and will not affect the indoor environment.

[0017] The roof panel 3 is detachably connected to the side-tilted flange 1D, and a supporting purlin 7 is provided on the lower surface of the side-tilted flange 1D. Specifically, a fixing bracket 9 is welded onto the roof panel 3. The structure of the fixing bracket 9 is prior art and will not be described in detail here. The bottom surface of the fixing bracket 9, the roof panel 3, the side-tilted flange 1D, and the supporting purlin 7 are connected by self-tapping screws.

[0018] An eaves drip plate 8 is provided between the bottom edge of the roof panel 3 and the side panel 1B. The eaves drip plate 8 includes an upper connecting part, a vertical part, and a downward sloping part facing the side panel 1B. The upper connecting part 3 is connected to the roof panel 3, the downward sloping part, and the side panel 1B by waterproof adhesive, which is convenient and can effectively guide rainwater into the gutter 1.

[0019] like Figure 3 As shown, the expansion joint cover plate 4 includes a central horizontal section and symmetrically arranged downward sloping sections on both sides of the horizontal section along its length, thus maintaining consistency with the orientation of the roof panel 3 and ensuring structural adaptability. The inner and outer sides of the gutter 1 are coated with anti-corrosion paint to improve its service life.

[0020] The steel structure building gutter expansion joint node in this embodiment improves the roof waterproofing effect through the structural design of the end of the roof panel 3 and the anti-seepage groove 5, and has the advantages of convenient and reliable connection and strong structural stability.
