[0002] To meet the demands of modern architectural design for energy efficiency, aesthetics, and a clean facade, the design of building curtain walls reduces the number of traditional operable windows. To achieve natural ventilation, energy conservation, and emission reduction while maintaining the building's aesthetic appeal, designers install concealed ventilators at the floor levels of the exterior decorative curtain wall units, allowing direct airflow between the interior and exterior. However, the presence of these ventilators also introduces new waterproofing challenges, particularly in windy and rainy weather, which can easily lead to leaks. Therefore, resolving waterproofing issues has become a key technical challenge in the design of building unitized curtain walls. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0025] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0026] In some embodiments, such as Figure 1 , Figure 2 and Figure 3 As shown, a silicone waterproofing system for unitized curtain wall energy-saving ventilators is provided. This system mainly includes a building floor slab 100, supporting columns 200, supporting horizontal members 300, and ventilators 400, designed to address the risk of water leakage when traditional ventilators are used on building facade glass curtain walls. Because airflow exchange occurs in the ventilator 400 area of the unitized curtain wall, condensation can easily form at the connection points of the supporting columns 200 and supporting horizontal members 300, potentially leading to rainwater leakage. To solve this problem, the following measures are taken in the design:
[0027] The two adjacent support columns 200 are connected by support crossbars 300. A ventilator 400 is installed along the length of the inner side of the support crossbar 300, and waterproof silicone gaskets 700 are installed at the connection points between the support columns 200 and the support crossbars 300. The waterproof silicone gaskets 700 are made of highly elastic, weather-resistant, and waterproof / impermeable materials. They are mainly used at the connection points between the support columns 200 and the support crossbars 300 of the unitized curtain wall, which are high-risk points for rainwater, condensate, and air leakage. By installing waterproof silicone gaskets 700 at these connection points, water leakage can be effectively blocked a second time, increasing the system's sealing performance.
[0028] The supporting horizontal member 300 includes a first horizontal member 310, a second horizontal member 320, and a third horizontal member 330 arranged at intervals. An exhaust port B connecting the ventilator 400 is formed between the second horizontal member 320 and the third horizontal member 330. The top of the third horizontal member 330 is set with a 2-5% slope, preferably a 3% slope, that is, the upper surface of the third horizontal member 330 is designed with a 3% slope from indoors to outdoors, which can make it easier for condensate and infiltrated rainwater to drain.
[0029] In some of these embodiments, such as Figure 1 As shown, the top of the building floor slab 100 is provided with a floor 101, and the outer side wall is provided with an L-shaped connector 102 for connecting the ventilator 400. The unit curtain wall of the ventilator 400 is arranged on the outer side, and its top is flush with the floor 101.
[0030] In some of these embodiments, such as Figure 2 As shown, each of the supporting columns 200 is composed of two sets of snap-fit aluminum alloy profiles and is fixed by bolts. The two aluminum alloy profiles are sealed together by a first sealant 201, and an adapter 202 is detachably installed on the outside by bolts. A vertically arranged decorative panel 203 is detachably installed on the outer end of the adapter 202.
[0031] In some of these embodiments, such as Figure 1 As shown, a curtain wall drainage groove A is formed between the first horizontal member 310 and the second horizontal member 320, which is the same as the third horizontal member 330. The top of the second horizontal member 320 is set with a 2-5% slope, preferably a 3% flashing slope.
[0032] In some of these embodiments, such as Figure 1 , Figure 4 and Figure 5 As shown, a vertically arranged water-blocking protrusion 331 is provided at the inner end of the top of the third horizontal member 330, and an outwardly extending edge 334 is provided at the outer end of the top. This allows the water flow to form a certain guiding and blocking effect when passing through this part, accelerating the outward diversion and further reducing the risk of water intrusion into the interior of the curtain wall.
[0033] Furthermore, an L-shaped groove 332 is provided on the inner wall of the third horizontal member 330. The two ends of the L-shaped groove 332 are sealed to the corresponding support column 200 with a second sealant 333 to meet the height adjustment requirements of the ventilator 400. The position and elevation of the ventilator 400 can be finely adjusted up and down with the screw 501. The two ends of the L-shaped groove 332 are sealed with sealant. This achieves the height adjustment of the ventilator 400 without sacrificing the overall airtightness and watertightness of the curtain wall.
[0034] In some of these embodiments, such as Figure 1 , Figure 2 and Figure 3 As shown, the ventilator 400 has a long, narrow structure, with its top surface flush with the floor 101 on the building floor slab 100, and is equipped with a flip-top cover 401. In use, the flip-top cover 401 is opened for natural ventilation. When not in use, the flip-top cover 401 can be manually closed to shut off the ventilator 400.
[0035] In some of these embodiments, such as Figure 1 and Figure 5 As shown, a ventilation duct 500 is provided between the air inlet of the exhaust port B and the ventilator 400. The ventilation duct 500 is a long strip structure and is located at the bottom of the ventilator 400.
[0036] Specifically, the ventilation duct 500 has an inverted L-shaped cross-section with plugs at both ends. The lower end is embedded in the L-shaped groove 332 on the inner side wall of the third horizontal material 330 and is locked and fixed with screws 501.
[0037] In some of these embodiments, such as Figure 1 and Figure 3 As shown, a ventilation plate 600 is provided at the air outlet of the exhaust port B, and the ventilation plate 600 is disposed between the second horizontal material 320 and the third horizontal material 330.
[0038] This utility model designs the upper surface of the horizontal member 300 with a 3% slope from the interior to the exterior for drainage, and sets an L-shaped groove 302 on the back of the horizontal member 330 to allow for height adjustment of the ventilator 400, enabling fine-tuning of the ventilator 400's position and elevation. Simultaneously, a waterproof silicone gasket 700 is used to seal the connection between the column 200 and the horizontal member 300, effectively preventing water leakage and increasing the system's sealing performance. This waterproof system, through multiple measures, improves the overall water tightness, air tightness, and energy-saving performance of the unitized curtain wall system with ventilators, thereby effectively reducing curtain wall maintenance costs, extending the curtain wall's service life, and meeting the higher requirements of modern curtain walls for energy saving, comfort, and durability.
