[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] As attached Figures 1-3 The siphonic rain gutter structure shown for reinforced concrete roof panels includes a reinforced concrete roof panel 1 and a siphonic rain gutter body 2 arranged in a reserved hole in the reinforced concrete roof panel 1, which is used to collect and discharge rainwater. A pressure plate 3 is provided on the top of the siphonic rain gutter body 2 for fixing and pressing a water-expanding waterstop strip 4 that expands when exposed to water. The expansion waterstop strip 4 is filled between the pressure plate 3 and the siphonic rain gutter body 2, which expands when exposed to water to form a waterproof seal. A concrete mortar layer 5 is provided between the siphonic rain gutter body 2 and the reserved hole in the reinforced concrete roof panel 1 for stabilizing the rain gutter and leveling it. The bottom of the siphonic rain gutter body 2 is connected to a rainwater pipe 6, and the gap between the rainwater pipe 6 and the reserved hole in the reinforced concrete roof panel 1 is filled with hydrophobic rock wool strips 7, with a filling depth of not less than 100 mm, for waterproofing and sealing.

[0025] Specifically, in this structure, the siphon rainwater bucket body 2 is the core component of the entire structure. It is responsible for collecting rainwater on the roof and draining the rainwater quickly and efficiently into the rainwater pipe 6 through its special design. The siphon rainwater bucket body 2 can be made of HDPE, cast iron or stainless steel, which has good durability and corrosion resistance.

[0026] The pressure plate 3 is arranged on the top of the siphon rainwater bucket body 2, playing the role of fixing and supporting, which can ensure that the rainwater bucket is firmly installed on the roof panel and prevent it from shifting or falling off due to wind or other external forces. The expansion water stop strip 4 is filled between the pressure plate 3 and the siphon rainwater bucket body 2 to form an effective waterproof barrier. When rainwater penetrates into this area, the expansion water stop strip 4 will absorb water and expand, thereby blocking the gap and preventing rainwater from leaking into the house.

[0027] The concrete mortar layer 5 is arranged between the siphon rainwater bucket body 2 and the reserved hole of the reinforced concrete roof panel 1. It plays the role of stabilizing the siphon rainwater bucket body 2 and leveling it, ensuring good contact and sealing between the siphon rainwater bucket body 2 and the roof panel, preventing rainwater from seeping into the house through the gap. At the same time, the concrete mortar layer 5 also has a certain strength and durability, and can withstand the weight of the rainwater bucket and various stresses during long-term use;

[0028] The rainwater pipe 6 is connected to the bottom of the siphon rainwater gutter body 2 and is responsible for discharging the collected rainwater. The rainwater pipe 6 is usually made of corrosion-resistant and wear-resistant materials to ensure its stability and reliability in long-term use. The hydrophobic rock wool strips 7 are filled in the gap between the rainwater pipe 6 and the reserved hole of the reinforced concrete roof panel 1 to play a role in waterproofing and heat preservation. The hydrophobic rock wool strips 7 have excellent waterproof and heat-insulating properties and can effectively prevent rainwater leakage and heat loss.

[0029] In short, the siphon rain gutter structure utilizes the siphon effect to quickly and efficiently drain rainwater on the roof into the drainage system, reduce the pressure of accumulated water on the roof, and protect the safety of the roof structure. Through the setting of multiple waterproof barriers such as the pressure plate 3, the expansion water stop strip 4, the concrete mortar layer 5 and the hydrophobic rock wool strip 7, the siphon rain gutter structure has excellent waterproof performance and can effectively prevent rainwater from leaking into the house.

[0030] In a specific embodiment, as shown in the attached Figure 1 As shown, it also includes a waterproof layer 8, which includes two layers of SBS waterproof membrane, one of which is an additional layer extending into the siphon rain gutter body 2, and the other layer is the main waterproof layer 8, covering the reinforced concrete roof panel 1 and extending to the inner wall and bottom of the reserved hole belonging to the reinforced concrete roof panel 1.

[0031] Specifically, in this structure, the waterproof layer 8 is composed of an additional layer and a main waterproof layer 8, wherein the additional layer extends into the siphon rain gutter body 2 and fits tightly with the rain gutter, thereby enhancing the waterproof performance around the rain gutter and preventing rainwater from leaking from the gap between the rain gutter and the roof panel, making the connection between the rain gutter and the roof panel more firm and the waterproof effect more reliable;

[0032] The main waterproof layer 8 covers the reinforced concrete roof panel 1 and extends to the inner wall of the reserved hole and the bottom of the panel, covering the entire roof area to form a comprehensive waterproof barrier, which can not only effectively prevent rainwater from seeping from the surface of the roof panel, but also prevent rainwater from seeping into the house from weak parts such as reserved holes.

[0033] In specific embodiments, as shown in the accompanying Figure 1 , 2 The outer side of the waterproof layer 8 is provided with a protective layer 9, which is composed of a finishing anti-cracking mortar 90 and a full-hanging glass fiber mesh 91.

[0034] Specifically, in this structure, the protective layer 9 is arranged on the outer side of the waterproof layer 8 and is composed of a finishing anti-cracking mortar 90 and a full-hanging glass fiber mesh 91, wherein the finishing anti-cracking mortar 90 has high bonding strength and anti-cracking performance, which can effectively prevent the waterproof layer 8 from cracking due to factors such as temperature changes and load effects. By applying anti-cracking mortar on the outer side of the waterproof layer 8, a dense protective layer 9 can be formed, reducing the direct damage of external factors to the waterproof layer 8 and improving the durability of the waterproof layer 8.

[0035] The glass fiber mesh 91 has high tensile strength and shear strength, which can significantly improve the overall structural strength of the protective layer 9 and enhance the stability of the structure. Moreover, it can also be tightly combined with the mortar to form a dense waterproof barrier, improving the protection effect.

[0036] In specific embodiments, as shown in the accompanying Figure 1 The lower part of the waterproof layer 8 is provided with a leveling layer 10 for drainage and leveling, which has a slope towards the rainwater collector with a slope ratio of 5%. The leveling layer 10 can be made of fine stone concrete material with a thickness of 40mm.

[0037] Specifically, the leveling layer 10 made of fine stone concrete material is arranged below the waterproof layer 8, which can effectively drain and level the roof, provide a solid foundation and good adhesion for the waterproof layer 8, protect the base structure from external damage, and significantly improve the durability and service life of the entire roof structure.

[0038] In specific embodiments, as shown in the accompanying Figure 1 , 3 The upper part of the reinforced concrete roof panel 1 is provided with a base treatment layer 11, which includes a 10mm thick cement mortar leveling layer 110 and a 20mm thick thermal insulation layer 111, and the thermal insulation layer 111 is an extruded polystyrene board thermal insulation layer.

[0039] Specifically, in the structure, the base treatment layer 11 above the reinforced concrete roof panel 1 includes the cement mortar leveling layer 110 and the extruded polystyrene board thermal insulation layer 111, effectively realizing the leveling treatment and thermal insulation function of the roof, and improving the overall energy efficiency and living comfort of the building.

[0040] In specific embodiments, as shown in the accompanying drawings, Figure 1 The siphon rainwater head body 2 is provided with a clamp at the connection with the reinforced concrete roof panel 1, and is connected through the clamp.

[0041] Specifically, in the structure, the siphon rainwater head body 2 is connected with the reinforced concrete roof panel 1 through the clamp, ensuring the stability and sealing of the rainwater head installation, effectively preventing rainwater leakage, and improving the overall efficiency of the drainage system.

[0042] The working principle of the utility model is:

[0044] Secondly, the siphon rainwater head body 2 is stably connected with the reinforced concrete roof panel 1 through the clamp, ensuring the stability and sealing of the rainwater head installation, effectively preventing rainwater from leaking from the connection;

[0045] Furthermore, the cement mortar leveling layer 110 in the base treatment layer 11 provides a flat foundation for the roof, which is conducive to the installation of the siphon rainwater head and the waterproof layer 8, and the extruded polystyrene board thermal insulation layer 111 improves the thermal insulation performance of the roof, thereby improving the energy efficiency and living comfort of the building;

[0046] In addition, the waterproof layer 8 is also a key link, the superposition of the two layers of SBS waterproof coiled material greatly enhances the waterproof performance of the waterproof layer 8, effectively preventing rainwater from penetrating from the roof to the indoor, and at the same time, the protective layer 9 on the outer side of the waterproof layer 8 is composed of a finishing anti-cracking mortar 90 and a full-hung glass fiber mesh 91, further improving the durability and stability of the waterproof layer 8;

[0047] Finally, the leveling layer 10 can be made of fine stone concrete material, which not only helps drainage, but also provides a good laying foundation for the waterproof layer 8, ensuring the close fit and sealing of the waterproof layer 8;
