Description

Technical Field

[0001] This utility model relates to the field of building curtain wall technology, and in particular to a glass curtain wall with micro-ventilation function in the interlayer sealing cavity. Background Technology

[0002] Aluminum panels are typically used to seal the space between the glass curtain wall and the building structure, serving to conceal the internal structure. This creates a closed cavity between the glass and the aluminum panels. During daily use, especially in summer, sunlight penetrates the glass and shines into this cavity, causing a large accumulation of heat. The significant temperature difference between the inside and outside of the glass leads to a sharp increase in thermal stress, which can easily cause the glass to shatter, posing a safety hazard. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model discloses a glass curtain wall with micro-ventilation function in the interlayer sealing cavity.

[0004] The specific technical solution is as follows: A glass curtain wall with micro-ventilation function in the interlayer sealing cavity includes glass and a keel. An aluminum plate is installed between two adjacent keels by screws A. The closed cavity formed between the glass and the aluminum plate is the interlayer sealing cavity. The middle part of the keel near the glass includes a protruding connecting end and a pressure plate. The pressure plate has an opening in the middle and is connected to the keel by screws B and nuts, pulling the pressure plate inward and clamping the glass inward. A sealing sleeve is installed on the outside of screw B by hooks. The sealing sleeve is sealed to the edge of the glass by foam rods and sealant. Ventilation holes A are opened on the keel near the interlayer sealing cavity and ventilation holes B are opened on the side near the glass. An L-shaped ventilation pipe is installed between the edge of the glass and the sealing sleeve. The ventilation pipe passes through foam rods, sealant and outer glass sealing strip in sequence. The air in the interlayer sealing cavity is connected to the outdoor air through ventilation holes A, ventilation holes B and ventilation pipes, forming a circulating micro-ventilation channel to create air convection.

[0005] The keel is an aluminum alloy column.

[0006] The column has mounting grooves A on both sides of the side closest to the glass for installing the inner sealant strip to seal the column and the glass; the pressure plate has mounting grooves B on both sides of the side closest to the glass for installing the outer sealant strip to seal the pressure plate and the glass.

[0007] The pressure plate is fitted with a cover via a hook.

[0008] The hole for mounting screw B at the connecting end is a telescopic hole perpendicular to the glass direction, providing telescopic space for screw B and nut to engage and tighten the pressure plate inside the room.

[0009] When the ventilation duct is installed, the opening on the outdoor side is tilted downwards.

[0010] Compared with the prior art, the present invention has the following beneficial technical effects: This utility model features a ventilation hole A near the interlayer sealing cavity on the column and a ventilation hole B near the glass side. An L-shaped ventilation pipe is installed between the glass edge and the sealing sleeve. The ventilation pipe passes sequentially through a foam rod, sealant, and outer glass sealing strip. During installation, the outdoor opening of the ventilation pipe faces downwards to prevent rainwater from entering the curtain wall. The air within the interlayer sealing cavity is connected to the outdoor air through ventilation holes A and B and the ventilation pipe, forming a circulating micro-ventilation channel. This allows for air convection, transforming the closed, stagnant air within the interlayer sealing cavity into a continuously circulating one. This removes heat from the cavity, and the convective circulation lowers the air temperature inside the cavity in summer, reduces the temperature difference between the inside and outside of the glass, reduces thermal stress, and significantly reduces the risk of glass spontaneous breakage.

[0012] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the accompanying drawings.

[0013] Figure 1 This is a detail diagram of the glass curtain wall of this utility model. The arrows in the diagram indicate air circulation channels, such as... Figure 1 As shown, this utility model discloses a glass curtain wall with micro-ventilation function in the interlayer sealing cavity, comprising glass 5 and a keel, wherein the keel is an aluminum alloy column 1. Mounting grooves A103 are formed on both sides of the column 1 near the glass 5 for installing the inner glass sealing strip 4, sealing the column 1 and the glass 5; mounting grooves B801 are formed on both sides of the pressure plate 8 near the glass 5 for installing the outer glass sealing strip 7, sealing the pressure plate 8 and the glass 5.

[0014] An aluminum plate 2 is installed between two adjacent columns using screws A3, serving to conceal the internal structure. The enclosed cavity formed between the glass 5 and the aluminum plate 2 is an interlayer sealing cavity. The keel, near the glass 5, includes a protruding connecting end 104 in its middle section, and also includes a pressure plate 8. The pressure plate 8 has a hole in the middle and is connected to the keel by screws B13 and nuts 9, pulling the pressure plate 8 towards the interior. The hole in the connecting end 104 for installing screws B13 is a telescopic hole 105 perpendicular to the direction of the glass 5, providing telescopic space for screws B13 and nuts 9 to pull the pressure plate 8 towards the interior. The pressure plate 8 clamps the glass 5 towards the interior, and a cover 10 is installed on the outside of the pressure plate 8 via hooks 802 for aesthetic decoration. A sealing sleeve 14 is installed on the outside of screw B13 via a hook. The sealing sleeve 14 is sealed to the edge of glass 5 with foam rod 6 and sealant 11. A ventilation hole A101 is opened near the interlayer sealing cavity on the column 1, and a ventilation hole B102 is opened near the glass 5. An L-shaped ventilation pipe 12 is installed between the edge of glass 5 and the sealing sleeve 14. The ventilation pipe 12 passes through foam rod 6, sealant 11, and outer glass sealing strip 7 in sequence. When installing the ventilation pipe 12, the opening on the outdoor side is tilted downwards to prevent rainwater from entering the curtain wall. The air in the interlayer sealing cavity is connected to the outdoor air through ventilation holes A101, B102, and ventilation pipe 12, forming a circulating micro-ventilation channel that allows air convection. In this way, the air in the interlayer sealing cavity changes from closed and stagnant to continuously circulating, which can remove heat from the cavity.
