Abstract
Description
Technical Field
[0001] This utility model belongs to the field of building curtain wall structure technology, and in particular relates to a curtain wall construction system equipped with a drainage device. Background Technology
[0002] As an important component of modern building facades, building curtain walls combine structural function with decorative effect, and are widely used in large public buildings and high-rise buildings. A curtain wall consists of panels and a support system, which not only bear external loads and ensure the performance of the building envelope, but also enhance the building's aesthetics through diverse materials and shapes. Especially against the backdrop of ever-increasing demands for aesthetics and functionality in modern architecture, curtain wall systems not only need to meet requirements for strength, rigidity, and safety, but also need to achieve excellent waterproofing, thermal insulation, airtightness, and durability.
[0003] Waterproofing design has always been a core issue in curtain wall systems. Traditional curtain wall designs typically rely on sealants as the primary waterproofing measure. The basic principle is to fill the joints of the panels with sealants such as silicone, polysulfide, and polyurethane to form a continuous barrier layer to prevent rainwater and air penetration. However, this method of relying entirely on sealant has significant limitations: sealants are high-molecular organic materials that are prone to aging over time, manifesting as hardening, powdering, loss of elasticity, cracking, or decreased adhesion; secondly, different sealants have varying compatibility with substrates such as stone, metal, and glass, and incompatibility can lead to bonding failure, such as poor adhesion (detachment) or contamination of the substrate (e.g., oil seepage into stone). Utility Model Content
[0004] The purpose of this invention is to provide a curtain wall construction system with a drainage device to solve the problems of existing curtain walls that fail due to aging and incompatibility between the sealant and the substrate.

The main frame vertical members 22 are connected to the exterior facade of the building wall 10 via main frame connectors 50. The main frame provides the foundation for connecting the curtain wall panels to the building wall; designing the main frame as a triangular structure provides an inclined plane on its hypotenuse. In a preferred embodiment of a curtain wall construction system equipped with a drainage device, such as... Figure 1 and Figure 2As shown, the main frame vertical rod 22 of the main frame 20 is provided with a main frame wall attachment hole 29, which can be a round hole, a vertical strip hole or a horizontal strip hole; the main frame connector 50 is fixedly connected to the building wall 10 by mechanical anchor bolts 51; the main frame vertical rod 22 is connected to the main frame connector 50 by bolts.

[0023] Waterproof membrane 60 is installed at an angle on the main frame diagonal bar 23 of the main frame 20, and the waterproof membrane 60 is located below the sub-frame; there is a water flow channel 61 between the perforated cover plate 100 and the waterproof membrane 60. A sink support is fixed inside the main frame 20, and a drain trough 80 is installed on the sink support; the projection of the lower edge of the waterproof plate 60 onto the plane containing the bottom surface of the drain trough 80 falls within the drain trough 80. In one specific embodiment, such as Figure 1 and Figure 3 As shown, the water tank support has an H-shaped structure. The waterproof plate 60 includes an upper waterproof plate and a lower waterproof plate. The lower edge of the upper waterproof plate has a downward bend that inserts into the drain trough 80, and the upper edge of the lower waterproof plate has an upward bend that inserts into the drain trough 80.
