Abstract
Description
Technical Field
[0001] This utility model belongs to the field of composite material door technology, and more specifically, it relates to an ultra-low energy consumption composite material door body and structure. Background Technology
[0002] Building energy consumption accounts for a significant proportion of daily energy consumption, and energy loss through doors and windows accounts for more than half of building energy loss. Doors and windows, as the building envelope, play a crucial role in building energy consumption. Existing unit doors are made of steel or thermally broken aluminum alloy profiles. Steel structures have low thermal insulation performance for the matching unit doors, while thermally broken aluminum alloy profiles, in order to meet thermal insulation requirements, generally use aluminum alloy materials on both sides with a thermal break strip in the middle, thus separating the indoor and outdoor aluminum alloys. However, due to changes in ambient temperature and humidity, thermal expansion and contraction reactions occur. The different thermal expansion coefficients of the two materials often cause gaps at the connection between the aluminum alloy material and the thermal break strip, reducing the mechanical connection strength of the profile and making it prone to water leakage and air leakage. Therefore, an ultra-low energy consumption composite material door body and structure is proposed. Utility Model Content
[0003] To address the shortcomings of existing technologies, this utility model provides an ultra-low energy consumption composite material door body and structure. Different sealing materials are selected based on the region and climate of use, and the structural dimensions of the variable pressure strip end face are matched with the door profile to form various structural forms and accommodate different glass thicknesses. This addresses the issue mentioned in the background technology where changes in environmental temperature and humidity cause thermal expansion and contraction. The different coefficients of thermal expansion of the two materials often lead to gaps at the connection between the aluminum alloy material and the thermal insulation strip, reducing the mechanical connection strength of the profile and making it prone to water seepage and ventilation. In contrast, while high-insulation window products are widely used in the market, matching insulated unit doors are relatively rare, especially low-energy consumption unit doors with ultra-high door panels, which are still a gap, mainly due to the large size and complex strength and structure of individual door panels.
[0004] To achieve the above objectives, this utility model provides the following technical solution: an ultra-low energy consumption composite material door body and structure, comprising two light switches, two crossbeams, a first glass, a second glass, a third glass, multiple first variable pressure strips, multiple second variable pressure strips, multiple third variable pressure strips, multiple sealing strips, multiple first sealing strips, multiple second sealing strips, and multiple third sealing strips. Two first slots are provided on opposite sides of each of the two light switches, and two second slots are provided on opposite sides of each of the two light switches. A third slot is provided on one side of each of the multiple first variable pressure strips, multiple second variable pressure strips, and multiple third variable pressure strips. A clamping strip is inserted into the inner side of each third slot. Two fourth slots are provided on opposite sides of each of the two crossbeams, and two fifth slots are provided on opposite sides of each of the two crossbeams.
[0005] As a preferred embodiment of this utility model, a plurality of first variable pressure strips are located on both sides of the first glass, a plurality of second variable pressure strips are located on both sides of the second glass, and a plurality of third variable pressure strips are located on both sides of the third glass.

[0008] As a preferred embodiment of this invention, the outer side of the sealing strip is inserted into the inner side of the second slot.

[0010] As a preferred embodiment of this utility model, the outer side of the sealing strip is inserted into the inner side of the fifth slot, and the outer side of the third sealing strip is inserted into the inner side of the fifth slot.
[0011] This utility model provides an ultra-low energy consumption composite material door body and structure, which has the following beneficial effects:
[0012] This ultra-low energy consumption composite material door body and structure features a variable pressure strip that snaps into the profile, making installation simple and efficient. By changing the structural dimensions of the variable pressure strip end face to match the door profile, various structural forms can be formed to accommodate different glass thicknesses, reducing the overall number of molds required for the door profile and minimizing mold expenditure. This modular design effectively reduces costs. Furthermore, considering the different insulation requirements in northern and southern regions, the door structure adopts a cavity design concept. For northern regions with higher requirements, polyurethane insulation material can be foamed in the cavity to achieve better insulation performance.
[0013] 2. This ultra-low energy consumption composite material door body and structure makes the main profile of the door structure simple, reduces the difficulty of production, processing and assembly, and reduces the cost of production and processing. At the same time, the overall end face design is flexible, which facilitates later modification and can speed up the launch of new products. It has better applicability. The composite material door body for the new unit door has successfully solved the shortcomings of traditional unit doors in terms of heat preservation, corrosion resistance and air tightness through material innovation, structural optimization and functional upgrade. It also takes into account cost and environmental protection requirements. Its flexible design and wide range of application scenarios make it an ideal choice for ultra-low energy consumption buildings or near-zero energy consumption buildings, with significant market value and social benefits.

This prevents gaps from forming when the profile expands and contracts due to heat, increasing waterproof and windproof sealing.

The modular design, which reduces mold expenditure and quantity, effectively lowers costs. Furthermore, considering the different insulation requirements in northern and southern regions, the door structure adopts a cavity design concept.

This design makes the main profile of the door structure simpler, reducing the difficulty of production, processing, and assembly, and lowering manufacturing costs. The flexible overall end-face design facilitates future modifications, accelerating the launch of new products and offering better applicability. The composite material door body of the new unit door, through material innovation, structural optimization, and functional upgrades, successfully solves the shortcomings of traditional unit doors in terms of insulation, corrosion resistance, and airtightness, while also considering cost and environmental protection requirements. Its flexible design and wide range of applications make it an ideal choice for ultra-low energy consumption buildings or near-zero energy consumption buildings, with significant market value and social benefits.
