Description

Technical Field

[0001] The utility model relates to the technical field of plastic-steel door and window profiles, in particular to a foldable-opening plastic-steel sliding energy-saving door. Background Technique

[0002] Plastic-steel profiles, abbreviated as plastic-steel, mainly composed of PVC, are also called PVC profiles. They are a new type of building material widely used. Due to their excellent physical properties such as rigidity, elasticity, corrosion resistance, and anti-aging performance, they are usually used as good substitutes for non-ferrous metals such as copper, zinc, and aluminum.

[0003] At present, plastic-steel profiles are used more and more in large openings and large-opening sliding doors in the building door and window market. Existing sliding door systems have differences in grid division methods, opening methods, and performance such as wind pressure resistance, airtightness, and heat preservation, and are far behind the market demand for large-opening plastic-steel sliding energy-saving doors with high quality and low energy consumption.

[0032] Embodiment 2

[0033] Please refer to Figures 1 - 4 , the difference between the foldable and opening plastic-steel sliding door provided in this embodiment and Embodiment 1 is as follows:

[0034] A first steel liner 13 is installed in the inner cavity of the outer frame 1 through a self-tapping screw clearance. Second steel liners 14 are respectively installed in the inner cavities of the sliding door leaf 2, the outward-opening door leaf 3, the sub-frame 4 and the outer frame insert 12 through self-tapping screw clearances. The first steel liner 13 and the second steel liners 14 can improve the strength of the outer frame 1, the sliding door leaf 2, the outward-opening door leaf 3, the sub-frame 4 and the outer frame insert 12, and can withstand the impacts from the environment, such as wind pressure and rain and snow attacks, and also bear the opening and closing forces and its own gravity during the use of this foldable and opening plastic-steel sliding energy-saving door.

[0035] Glass pads are respectively placed on one side of the sliding door leaf 2 and the outward-opening door leaf 3 close to the corresponding insulating glass 5. One side of the glass pad contacts the corresponding insulating glass 5. Through the glass pads, reverse water can be avoided between the insulating glass 5 and the sliding door leaf 2, and between the insulating glass 5 and the outward-opening door leaf 3, and the self-tapping screw caps of the second steel liner 14 can be prevented from contacting the insulating glass 5. At the same time, when this foldable and opening plastic-steel sliding energy-saving door vibrates, it can play an anti-seismic buffering role for the insulating glass 5.

[0036] The sealing rubber strips C63, D64, F72, I75 and K82 are all made of foamed rubber strips, which can effectively block the convection of air and the effect of heat conduction, and improve the heat preservation, air tightness and sound insulation of this foldable and opening plastic-steel sliding energy-saving door.

[0037] In summary, this foldable and opening plastic-steel sliding door is assembled by adopting an assembly method combining welding and screwing, which is convenient for the production, transportation and installation of large-sized doors; at the same time, through the sub-frame 4, the overall watertightness and heat preservation performance of the door can be improved, as well as the convenience of later installation. It is an ideal energy-saving product suitable for high-performance and large-opening requirements, meeting the maximum opening amount and partitioning large and large-opening spaces.
