Description

Technical Field

[0001] This utility model belongs to the technical field of building doors and windows, specifically relating to a narrow-frame lift-up sliding steel door system. Background Technology

[0002] The energy-saving performance of existing building doors and windows is receiving increasing attention. However, traditional sliding doors have significant structural defects: Firstly, their sealing strips (including weatherstripping) are constantly in frictional contact with the frame during opening and closing, leading to wear and tear over time and a decline in airtightness, watertightness, and thermal insulation performance. Secondly, the weight of the door leaf is entirely supported by the outer frame, which restricts the door leaf size design and affects the user experience. Furthermore, while traditional sliding doors save space compared to hinged doors, their sealing performance is insufficient, making it difficult to meet the stringent energy-saving and environmental protection requirements of high-end buildings. Therefore, there is an urgent need for a sliding door solution that can reduce frictional wear, extend the life of sealing components, and optimize the load-bearing structure. Utility Model Content

[0024] Example

[0025] Reference Figures 1-4 This is an embodiment of the present invention, which provides a narrow-frame lift-up sliding steel door system, including:

[0026] The door frame assembly 100 includes a door frame 110, an upper track profile 120 fixedly installed on the top of the door frame 110, and a lower track profile 130 fixedly installed on the bottom of the door frame 110. Both the upper track profile 120 and the lower track profile 130 are provided with slide rails 140.

[0027] Door assembly 200 includes an outdoor door 210 and an indoor door 220, which are slidably connected to a slide rail 140.

[0028] The door panel assembly 200 also includes an entry rail profile 230 disposed on the upper frame, a pulley seat 240 disposed on the lower frame, a pulley 250 that cooperates with the slide rail 140 mounted on the pulley seat 240, a hook 260 disposed on one side frame, and a locking hardware 270 and a handle 280 disposed on the other side frame.

[0029] The sealing assembly 300 includes an upper sealing structure 310, a lower sealing structure 320, and a vertical sealing structure 330 disposed between the door leaf assembly 200 and the door frame assembly 100.

[0030] The sealing assembly 300 also includes a windproof block 340 disposed in the inner cavity of the upper rail profile 120, a weatherstripping 350 disposed between the entry rail profile 230 and the upper rail profile 120, and a double sealing strip 360 fixedly installed between the pulley seat 240 and the lower rail profile 130.

[0031] Among them, the door frame component 100 adopts a 25mm narrow frame design, which is visually simple and modern, while the 170mm depth ensures structural strength and stability, making it suitable for large-size door installations; the slide rail 140 is made of high-strength aluminum alloy, which is wear-resistant and runs smoothly, ensuring that the door is not easily deformed or stuck during long-term use.

[0032] The door panel assembly 200 features a 47mm narrow frame combined with 75 series thermally broken steel profiles. While ensuring strength, it maximizes the glass area, enhances lighting, and makes the space more transparent. The pulley base 240 and pulley 250 adopt a precision bearing structure, making pushing and pulling easy and quiet, reducing friction loss, and extending service life. The hook 260 and locking hardware 270 fit tightly to ensure the stability and security of the door when closed and prevent external prying. The handle 280 is ergonomically designed, making operation effortless and improving the user experience.

[0033] The weatherstripping 350 and the double sealing strip 360 form multiple sealing barriers, enhancing the thermal insulation effect and reducing energy consumption. The upper sealing structure 310, the lower sealing structure 320 and the vertical sealing structure work together to reduce air infiltration and improve air tightness and water tightness, making it suitable for high wind pressure areas.

[0034] Specifically, the door frame 110 is constructed by welding thermally broken steel profiles with a visible width of 25mm and a depth of 170mm. The upper track profile 120 and the lower track profile 130 are provided with water collection grooves 150 and drainage holes 160 on their outer sides. Polyurethane can be poured into the door frame 110, which has the advantages of high strength and low thermal conductivity, and can easily meet the high requirements of buildings for the thermal insulation performance and wind pressure resistance of doors and windows.

[0035] The upper rail profile 120 and the lower rail profile 130 are equipped with a water collection trough 150 and a drainage hole 160, which effectively prevents rainwater accumulation, improves waterproof performance, and avoids leakage problems.

[0036] Furthermore, the door panel assembly 200 is constructed from 75 series thermally broken steel profiles with a visible width of 47mm and a depth of 72mm.

[0037] Furthermore, the windproof block 340 seals the gap between the outdoor door leaf 210 and the indoor door leaf 220 when the door leaf is closed, and the weight of the door leaf assembly 200 is evenly transferred to the slide rail 140 through the pulley 250. The slide rail 140 is made of high-strength aluminum alloy material.

[0038] Among them, the windproof block 340 automatically fills the gaps when the door is closed, effectively blocking wind, sand, rain and noise, and improving the overall sealing performance.

[0039] When in use, as the door panel assembly 200 slides along the slide rail 140, its weight is evenly transmitted to the track through the pulley 250, and the semi-suspended design greatly reduces frictional resistance.

[0040] During the closing process, the windproof block 340 automatically pops out to fill the gap in the door leaf, while the weatherstripping 350 and the double sealing strips 360 are tightly attached to form a three-dimensional sealing network.

[0041] When it rains, the water collection trough 150 drains water quickly through the drainage hole 160 with the siphon effect, ensuring that there is no water accumulation on the track and achieving efficient operation that is easy to push and fits tightly.

[0042] In summary, the door frame assembly 100, with its 25mm ultra-narrow frame and 170mm deep thermally broken steel profile, achieves ultra-high strength while maintaining a clean visual appearance, capable of supporting extra-large door panels. The door panel assembly 200 uses a 47mm narrow-edge 75-series steel profile as its frame, combined with precision bearing pulleys 250 and welded corner assembly technology, making sliding smoother and preventing sagging over long-term use. The sealing assembly 300 forms multiple barriers through windproof blocks 340, double sealing strips 360, and a siphon drainage system, improving airtightness by more than 3 times and reducing thermal conductivity by 60%. It also features an extra-large opening space and excellent thermal insulation, sound insulation, and waterproof performance, meeting the stringent energy-saving and environmental protection requirements of high-end buildings.
