[0024] This utility model provides an improved, leak-proof installation node for complex gutters. The technical solution of this utility model is as follows:
[0025] like Figures 1-3 As shown, a complex leak-proof gutter installation node includes a concrete wall 1 and a curtain wall aluminum panel 10, which provides a construction foundation for the subsequent installation of the roof and gutter 8, and also includes;
[0026] Gutter 8 is installed between the concrete wall 1 and the aluminum curtain wall panel 10. Stainless steel pipe 18 is welded on the gutter 8. The gutter 8 collects rainwater from the roof in a centralized manner and discharges it in a directional manner, avoiding problems such as rainwater splashing and wall erosion caused by unorganized drainage, and protecting the structural integrity.
[0027] Wing plate 2 is fixedly installed on the side and top of the concrete wall 1. Using high-strength steel or composite materials, wing plate 2 enhances the building's resistance to deformation and improves safety.
[0028] Furthermore, angle steel 11 is welded to the surface of the aluminum curtain wall panel 10, and a pair of square tubes 17 are fixedly connected inside the aluminum curtain wall panel 10. A waterproof membrane 4 is fixedly installed on the top of the wing plate 2, and mortar 3 is poured on the top of the waterproof membrane 4. A self-tapping screw 7 is threaded on one end of the waterproof membrane 4. The gutter 8 is threaded onto the waterproof membrane 4 through the self-tapping screw 7. The membrane thickness is standardized, and a continuous waterproof layer can be formed by overlapping or welding during construction, avoiding the risk of leakage caused by uneven coating. Moreover, the material usage is accurately calculated, reducing waste.
[0029] Furthermore, multiple bottom tiles 6 are fixedly installed on the top of the waterproof membrane 4, and a cover tile 5 is fixedly installed on the top of each bottom tile 6. A pair of fastening bolts 15 are threaded on the angle steel 11, and an outer eaves support plate 9 is threaded on the angle steel 11 through the fastening bolts 15. In addition, a leaf-proof mesh is fixedly connected to one side of the gutter 8 with self-tapping screws to avoid poor drainage due to blockage and improve the drainage performance of the structure.
[0030] Furthermore, one side of the aluminum panel 10 of the curtain wall and the bottom of the gutter 8 are jointly installed with angle steel 12. The bottom of the gutter 8 is provided with a drain outlet 16. A waterproof mesh cover 13 is fixedly installed on the drain outlet 16. A downpipe 14 is fixedly installed on the drain outlet 16.

[0031] The specific working method is as follows: First, the curtain wall unit will make openings and positioning based on the electromechanical downpipe 14 and the exhaust duct to install the square tube 17. After the openings are completed, the curtain wall aluminum panel 10 will be installed. Second, before the construction of the gutter 8, the eaves structure will be sloped by grouting, and the slope will be consistent with the edge of the gutter 8 to ensure that the gutter 8 fits snugly with the eaves. The gutter 8 will be opened according to the holes of the downpipe 14 on the curtain wall aluminum panel 10. The stainless steel pipe 18 will be welded to the gutter 8 and fitted into the downpipe 14. After the gutter 8 is installed, if water leakage is found through air holes, it will be ground with a grinder and re-welded. The stainless steel gutter 8 will be welded using argon arc welding with stainless steel wire as the welding rod. The gutter 8 will be placed on the left side of the keel. The bottom elevation control line is established. Angle steel 212 is welded according to the control line. Angle iron is used to support gutter 8. After gutter 8 is installed and fixed, polymer modified bitumen waterproof membrane 4 is used as an additional layer to cover the flange of gutter 8, pressing down the wing plate 2. The waterproof membrane 4 is covered with mortar 3 during the roof tile construction to prevent rainwater from seeping through the gap between gutter 8 and eaves. The joint between the exhaust duct and gutter 8 is sealed by the electromechanical unit. The joint between gutter 8 and curtain wall aluminum plate 10 is sealed by the curtain wall unit. Finally, the roof is constructed. First, the roof is leveled, lines are drawn and the water strips and tile strips are fixed. Then, the eaves tiles, bottom tiles 6 and top tiles 5 are laid. After the ridge tiles are laid, the roof is cleaned.
