Referring to fig. 1-3, the present utility model provides a gutter node that can ensure the water resistance of the gutter connection with the fused mirror roof 100 while achieving gutter drainage.

Referring to fig. 1, fig. 1 is a schematic diagram of a gutter node according to some embodiments of the present utility model. The gutter node shown in fig. 1 includes a roof 100 and a gutter structure. Wherein the roof 100 is a fused mirror plate that is secured to a first purlin 103 of the building. Specifically, the fusion mirror plate can be secured to the first purlin 103 by fasteners 218, and the fasteners 218 can be BIPV-specific self-tapping nails. The fusion mirror plate comprises a plurality of plane composite plates. In particular, the roof 100 is formed from a plurality of planar composite panels that are spliced together. The planar composite board sequentially comprises a TPO layer, a metal plate layer and an insulation layer along the thickness direction. Wherein the TPO layer is oriented to the outside of the building. The TPO layer has good waterproof performance and weldability, can ensure the waterproof function of the roof 100, and can be welded with the photovoltaic module through hot air welding and the like, so that the photovoltaic module is convenient to install. The TPO layer, the metal plate layer and the heat preservation layer can be bonded by gluing. The gutter structure shown in FIG. 1 is an inner gutter structure that includes an inner gutter 201-1 and an inner gutter bracket 202-1. The inner gutter 201-1 is concave and the gutter bottom 2013 is fixed to the inner gutter bracket 202-1. The inner gutter bracket 202-1 may be a C-section steel. When the inner gutter 201-1 is installed, the C-shaped steel of the inner gutter bracket 202-1 may be fixed to a steel structure of a building, for example, to a purline, and then the inner gutter 201-1 may be fixed to the C-shaped steel, so that the inner gutter 201-1 may be fixed. At least one side of the inner gutter 201-1 is bent outwards to form a first fixing portion 2011. The first fixing portion 2011 is fixed below the roof 100 fusion mirror plate. As shown in fig. 1, a first fixing portion 2011 is fixed between the roof 100 and the first purlin 103. The first fixing part 2011 of the inner gutter 201-1 is fixed below the roof 100 fusion mirror plate, so that the leakage risk caused by exposure of the fixing part of the inner gutter 201-1 and the roof 100 fusion mirror plate can be avoided while the drainage function of the inner gutter 201-1 is ensured. Further, the first fixing portion 2011 is fixed between the roof 100 and the first purline 103, which can facilitate the installation of the inner gutter 201-1.

Further, the fusion mirror plate comprises an extension 101. The extension part 101 is disposed on one side of the fusion mirror plate, which is close to the gutter, and extends outwards away from the fusion mirror plate. The end of the extension 101 is fixed inside the inner gutter 201-1. The end of the extension 101 and the inside of the inner gutter 201-1 may be secured by the waterproof strip 102. Alternatively or preferably, the waterproof strip 102 may be an acrylic tape or a butyl tape. Alternatively or preferably, the waterproof strip 102 may be a butyl tape. The butyl adhesive tape has good waterproof property, corrosion resistance, high bonding strength and high tensile strength. The butyl tape can prevent rainwater from penetrating into the inner face of the inner gutter 201-1 from the gap between the extension 101 and the inner gutter 201-1. In one possible manner, the waterproof strip 102 may be replaced by an adhesive, for example, a sealant may be applied between the end of the extension 101 and the inside of the inner gutter 201-1, and the extension 101 and the inner gutter 201-1 may be fixed by the sealant. The extension 101 may be made of a TPO film-coated metal plate. The TPO film-covered metal plate comprises a TPO layer and a metal plate layer, and the TPO layer and the metal plate layer can be bonded in an adhesive mode. As shown in fig. 1, one end of an extension 101 made of a TPO film coated metal plate may be secured to a fusion mirror plate by fasteners 104. Fastener 104 may be a blind rivet. The fasteners 104 may also be covered with a flashing strip 105. The waterproof strip 105 may be a TPO waterproof strip, so that the integrity of the waterproof performance of the roof 100 may be ensured by hot air welding the waterproof strip 105 and sealing the TPO layer of the fused mirror plate. In one possible approach, the TPO film coated metal plate of the extension 101 may also be integrally formed with the TPO layer and metal plate layer of the fused mirror plate. For example, when the fusion mirror plate is produced or assembled, after the TPO layer and the metal plate layer are bonded, a certain width is reserved as the extension portion 101 without bonding the heat insulating layer. Thus, the extension part 101 and the roof 100 are integrated into a whole, the integral structure of the roof 100 is not damaged, the integrity of the roof 100 is ensured, and the waterproof performance is ensured.

The gutter node in the gutter node embodiment shown in FIG. 1 also includes parapet walls. Parapet wall 210 is a fused mirror plate.

The second securing portion 2012 is secured to the first transverse wall beam 211 by a fastener 213. The gutter node is also provided with a second transverse wall beam 212 and parapet cover plate 215. The second transverse wall beam 212 is disposed above the first transverse wall beam 211 and is fixed to the parapet wall surface 210 by fasteners 214. The fasteners 213 and 214 may be BIPV-specific self-tapping screws or screws. Parapet cover plate 215 completely covers the top of parapet wall 210 and second transverse wall beam 212. The parapet cover plate 215 has a third fixing portion 2151 and a fourth positioning portion at both sides thereof, respectively. The third fixing portion 2151 is fixed to a side of the parapet wall 210 away from the gutter, and the fourth positioning portion is fixed to a side of the second transverse wall beam 212 close to the gutter. The third and fourth fixed portions 2151 and 2152 house the fasteners 214 and 226, respectively. Plugs 216 are arranged outside the fasteners on one side, close to the inner gutter 201-1, of the first transverse wall beam 211 and the second transverse wall beam 212. The fourth fixing portion 2152 is fixed to the plug 216 by a fastener 226, and the outside of the fastener 226 covers the waterproof strip 217. The waterproof strip 217 may be a TPO waterproof strip having good waterproof performance while having weldability. If the surface of the parapet cover plate 215 is covered with the TPO layer, the TPO waterproof strip 217 and the parapet cover plate 215 may be welded and fixed by hot air, so that rainwater may be prevented from leaking into the interior of the building from the junction between the parapet cover plate 215 and the parapet wall 210 or the steel structure or the cross beam of the building, and the tightness and waterproof performance between the parapet cover plate 215 and the parapet wall 210 are ensured.

Further, the gutter node is further provided with an overflow 219. The overflow 219 is inclined with the inlet at the high end and the outlet at the low end. The height of the inlet of the overflow pipe 219 in the vertical direction is higher than the height of the gutter bottom 2013 of the inner gutter 201-1, the outlet is positioned on the outer side of the parapet wall surface 210, and the height of the outlet in the vertical direction is lower than the height of the gutter bottom 2013 of the inner gutter 201-1.

Reference is made to fig. 2 and 3. FIG. 2 is a schematic illustration of a gutter node according to further embodiments of the present utility model; fig. 3 is a partial enlarged view of fig. 2.
