Description

Technical Field

[0001] This utility model relates to the field of curtain wall construction technology, specifically to a glass curtain wall thermal insulation partition system. Background Technology

[0002] In the 1980s, glass curtain wall systems were introduced to my country and, thanks to their advantages such as uniform facade and excellent lighting, were quickly and widely used in public buildings. However, translucent glass curtain walls inherently have shortcomings in thermal insulation. After long-term use, they not only result in poor indoor thermal comfort and high heating and cooling loads, but also often suffer from leakage problems. The keel area is a particularly weak link in the thermal insulation partition.

[0003] Existing glass curtain wall keels generally use aluminum alloy profiles, which have a high thermal conductivity and lack targeted insulation design at the joints. This results in the insulation performance of the keel area being far lower than that of the glass panels. In winter, low-temperature condensation easily occurs due to heat transfer, while in summer, concentrated radiant heat causes high indoor temperatures, severely damaging the overall insulation and partitioning effect of the curtain wall. At the same time, the traditional keel sealing structure design is rudimentary, often relying on a single sealant or sealing strip. After long-term use, it is prone to aging and cracking, causing water seepage and air leakage problems, which further weakens the insulation performance and seriously affects the building's functionality and durability.

[0004] The following technical problems exist in the technical optimization of keel-insulated partitions: existing solutions mostly only provide simple insulation wrapping for the indoor side, without targeted sealing and insulation design for key parts such as the gap between the keel and the glass panel and the cavity of the components, which cannot block the heat conduction path inside the keel; and a multi-layered collaborative protection system has not been formed, and it is difficult to meet the multiple requirements of insulation, waterproofing, airtightness and radiant heat resistance by relying on a single material, and it cannot completely solve the core problems such as thermal bridging, condensation and leakage. Utility Model Content

[0005] The purpose of this invention is to provide a glass curtain wall thermal insulation partition system that solves the technical problems of thermal bridging, condensation, water seepage, and air leakage in traditional curtain wall keels.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A glass curtain wall thermal insulation partition system includes a keel curtain wall, tempered vacuum glass, glass pressure plates, decorative cover plates, a first thermal insulation layer, a second thermal insulation layer, a third thermal insulation layer, and a fourth thermal insulation layer. The keel curtain wall includes a front-end component and a rear-end component, both of which are arranged in a grid pattern and installed opposite each other on the main structure. Multiple thermal insulation strips are spaced between the front-end and rear-end components. Tempered vacuum glass is installed at the grid points. A decorative cover plate is fastened to the outside of the glass pressure plate. A glass pressure plate is detachably installed at the front-end component. The first thermal insulation layer fills the space between the tempered vacuum glass and the keel curtain wall. The second thermal insulation layer is integrated into the joint between two adjacent tempered vacuum glass panes and at the front-end component. The third thermal insulation layer is thermally insulated and sealed on the glass pressure plate. The fourth thermal insulation layer provides thermal insulation and decoration for the rear-end component.

[0007] Preferably, the rear end component includes multiple horizontal keels and multiple vertical keels, with two slots provided on the front side of each horizontal keel and each vertical keel, and a support base provided at each slot.

[0008] Preferably, the first thermal insulation layer includes EPDM rubber strip A, which is filled between the support base and the side of the tempered vacuum glass; the first thermal insulation layer also includes flame-retardant micro-expansion thermal insulation and sealing foam, which is filled in the cavity formed by the front end component, the rear end component, the periphery of the tempered vacuum glass and the second thermal insulation layer.

[0009] Preferably, the second thermal insulation layer is a butyl tape that seals the gap between the front side of the tempered vacuum glass and the front end component.

[0010] Preferably, a fourth thermal insulation layer is provided on the upper, rear, and lower sides of the rear end component. The fourth thermal insulation layer includes a first insulation board, a second insulation board, and a third insulation board. The first insulation board is connected to the support base and located on one side of the rear end component. The second insulation board is connected to the support base and located on the other side of the rear end component. The third insulation board is snapped onto the ends of the first and second insulation boards. Thermal insulation material is filled in the first, second, and third insulation boards. EPDM rubber strip C is filled between the first insulation board and the tempered vacuum glass, and EPDM rubber strip C is also filled between the second insulation board and the tempered vacuum glass.

[0011] Preferably, the third thermal insulation layer includes a nano-aerogel thermal insulation coating, a neutral silicone weather-resistant sealant coating, and an EPDM rubber strip B. The nano-aerogel thermal insulation coating is provided on the outer side of the glass pressure plate, the EPDM rubber strip B is filled between the glass pressure plate and the tempered vacuum glass, and the joint is sealed with a neutral silicone weather-resistant sealant coating.

[0012] In this utility model, a multi-dimensional protection system with complementary functions is constructed, which completely solves the technical problems of thermal bridging, condensation, water seepage, and air leakage in traditional curtain wall keels. The first thermal insulation layer consists of EPDM rubber strip A and flame-retardant micro-expansion thermal insulation and sealing foam. The former is adapted to the gap between the support base and the tempered vacuum glass to achieve basic sealing and thermal insulation, while the latter fills the cavity of the component, simultaneously playing a triple role of thermal insulation, waterproofing and airtightness, blocking heat exchange and leakage from the source. The second layer of butyl tape seals the gap between the tempered vacuum glass and the front-end components, strengthens the seal continuity, compensates for the aging and cracking defects of traditional sealants, and synergistically improves the sealing and heat preservation performance. The third layer blocks radiant heat through a nano-aerogel heat insulation coating on the outside of the glass pressure plate, and seals the joints with EPDM rubber strip B and neutral silicone weather-resistant sealant coating to precisely solve radiative heat exchange and local leakage. The fourth and above side insulation boards, the second insulation board and the third insulation board form a three-dimensional protection. The three are connected to the inner cover by stepped flange clips to achieve integrated insulation and decoration, and complete the insulation closed loop. Attached Figure Description
