Description

Technical Field

[0001] This utility model relates to the field of construction, specifically to a building envelope structure. Background Technology

[0002] Currently, high-rise office buildings commonly adopt all-glass curtain wall structures to achieve aesthetically pleasing facades. However, this design leads to a significant increase in indoor temperature and the accumulation of a large amount of heat, causing buildings to rely heavily on air conditioning systems for temperature regulation and resulting in excessive energy consumption. Most shading solutions on the market are simple horizontal or vertical shading components, which, while mitigating solar radiation to some extent, negatively impact natural lighting, leading to uneven lighting or insufficient illumination, thus affecting the comfort of the office environment.

[0003] Furthermore, due to the unique characteristics of high-rise buildings, conventional window designs present numerous problems: First, excessive wind pressure at high altitudes can impair the normal use of windows; second, in severe weather conditions, open windows pose significant safety hazards due to breakage and falling; simultaneously, high-rise windows also lead to significant noise pollution, impacting the indoor office environment. These issues severely restrict the natural ventilation and lighting of high-rise office buildings, and also increase the difficulty and risks of building operation and maintenance. Utility Model Content

[0004] The purpose of this invention is to provide a low-energy-consumption and low-noise building envelope structure.

[0005] In this embodiment of the utility model, a building envelope structure is provided, comprising: a plurality of cell units fixed to the exterior facade of the building, each cell including a right-angled trapezoidal top surface and a right-angled trapezoidal bottom surface respectively on the same plane as the upper and lower floors, a first side surface located between the lower base of the right-angled trapezoids on the top surface and the bottom surface, a second side surface located between the upper base of the right-angled trapezoids on the top surface and the bottom surface, and a front surface located between the sloping sides of the right-angled trapezoids on the top surface and the bottom surface. The front surface is covered with tempered glass. The first side surface is provided with a fixed tempered glass panel and an aluminum alloy window sash disposed on the fixed tempered glass panel. A composite perforated plate covering the fixed tempered glass panel and the aluminum alloy window sash is also provided on the outer side of the first side surface.

[0006] In this embodiment of the utility model, both the top surface and the bottom surface include a first aluminum alloy crossbeam located on the right-angled side of a right trapezoid and a second aluminum alloy crossbeam located on the inclined waist of a right trapezoid. The second aluminum alloy crossbeam is connected to the first aluminum alloy crossbeam through a steel rectangular tube. The two first aluminum alloy crossbeams located on the upper and lower floors are connected through an aluminum alloy unit frame, and the two second aluminum alloy crossbeams located on the upper and lower floors are connected through an aluminum alloy central vertical frame.

[0007] In this embodiment of the present invention, on the first side, the aluminum alloy window sash is fixed to the aluminum alloy unit frame and the aluminum alloy middle vertical frame respectively.

[0008] In this embodiment of the utility model, a base plate is provided on the bottom surface of the steel rectangular tube in the cell.

[0009] In this embodiment of the invention, a gap is provided between two cells located on the same layer, and tempered glass is used to cover the gap.

[0010] In this embodiment of the present invention, the composite perforated plate is composed of holes of different diameters on the inner and outer sides and a sound-absorbing material in the middle, and the pores on the outer side are larger than the pores on the inner side.

[0011] Compared with existing technologies, the building envelope structure of this utility model features trapezoidal unit cells. The front of each unit cell is covered with tempered glass, allowing for direct sunlight. The side windows of the unit cells ensure unobstructed views and landscapes to the south while providing self-shading through a serrated arrangement. Simultaneously, composite perforated panels reflect sunlight, reducing afternoon sun exposure and maximizing energy conservation and emission reduction. The outer side of the first side is equipped with a composite perforated panel covering the fixed tempered glass and the aluminum alloy window sash. This panel consists of holes of different diameters on the inner and outer sides, and sound-absorbing material in the middle. The outer pores are larger than the inner pores, achieving sound absorption and noise reduction through variable cross-section holes. The composite perforated panel on the outer side and the inner aluminum alloy window sash on the inner side ensure consistency and integrity of the exterior building effect when the windows are open or closed, while also guaranteeing natural ventilation. This significantly reduces safety hazards associated with high-rise window openings, avoids excessive wind resistance in high-rise buildings, and solves the problem of windows being inaccessible during inclement weather.

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0017] The implementation of this utility model will be described in detail below with reference to specific embodiments.

[0018] like Figure 1 As shown in the present invention, an external building envelope structure is provided, comprising: a plurality of cell units 10 fixed to the exterior of the building, each cell unit 10 comprising a right-angled trapezoidal top surface and a right-angled trapezoidal bottom surface respectively on the same plane as the upper and lower floors, a first side surface located between the lower base of the right-angled trapezoids of the top surface and the bottom surface, a second side surface located between the upper base of the right-angled trapezoids of the top surface and the bottom surface, and a front surface located between the inclined sides of the right-angled trapezoids of the top surface and the bottom surface.

[0019] like Figure 2 and Figure 3 As shown, both the top and bottom surfaces include a first aluminum alloy beam 11 located on the right-angled side of a right-angled trapezoid and a second aluminum alloy beam 12 located on the inclined side of the right-angled trapezoid. The first aluminum alloy beam 11 is fixed to the building floor slab. The second aluminum alloy beam 12 is connected to the first aluminum alloy beam 11 via a steel rectangular tube 13. The two first aluminum alloy beams 11 located on the upper and lower floors are connected by an aluminum alloy unit frame 14, and the two second aluminum alloy beams 12 located on the upper and lower floors are connected by an aluminum alloy central vertical frame 15. A stable outer frame for the cell is formed by the adjacent aluminum alloy beams 11 and 12 on the upper and lower floors, as well as the aluminum alloy unit frame 14 and the aluminum alloy central vertical frame 15. A base plate 16 is provided on the steel rectangular tube 13 on the bottom surface of the cell 10, thereby supporting users walking on the cell 10.

[0020] It should be noted that, in this embodiment of the invention, the aluminum alloy unit frame 14 and the aluminum alloy vertical frame 15 are closely adjacent to each other on the second side of the cell 10. In other implementations, the aluminum alloy unit frame 14 and the aluminum alloy vertical frame 15 may also have a certain gap on the second side of the cell 10, and tempered glass may be placed in the gap.

[0021] The front of the outer frame of the cell is covered with tempered glass 17. A fixed tempered glass pane 18 and an aluminum alloy window sash 19 are disposed on the first side of the cell 10. The aluminum alloy window sash 19 is fixed to the aluminum alloy unit frame 14 and the aluminum alloy central vertical frame 15, respectively. A composite perforated plate 20 covering the fixed tempered glass pane 18 and the aluminum alloy window sash 19 is also provided on the outer side of the first side of the cell 10.

[0022] like Figure 4 As shown, the composite perforated plate 20 is composed of holes of different diameters on the inner and outer sides and sound-absorbing material in the middle, and the pores on the outer side are larger than those on the inner side. The purpose of sound absorption and noise reduction is achieved by changing the pores on the inner and outer sides.

[0023] In this embodiment of the invention, a gap is provided between two cells 10 located on the same layer, and tempered glass is used to cover the gap. The plurality of cells 10 form a sawtooth-shaped external maintenance structure. Of course, in other embodiments of the invention, two cells 10 located on the same layer may also be adjacent to each other. The specific structure is set according to actual needs, and the invention does not limit this.

[0024] In summary, the building envelope structure of this utility model features trapezoidal unit cells. The front of each unit is covered with tempered glass, allowing for direct sunlight. The side windows of the unit cells ensure unobstructed views and landscapes to the south while providing self-shading through a serrated arrangement. Simultaneously, the composite perforated panel reflects sunlight, reducing afternoon sun exposure and maximizing energy conservation and emission reduction. The outer side of the first side is equipped with a composite perforated panel covering the fixed tempered glass and the aluminum alloy window sash. This panel consists of holes of different diameters on the inner and outer sides, along with sound-absorbing material in the middle. The outer pores are larger than the inner pores, achieving sound absorption and noise reduction through the variable cross-section of the perforations. The composite perforated panel on the outer side and the inner aluminum alloy window sash on the inner side ensure consistency and integrity of the exterior building effect when the windows are open or closed, while also guaranteeing natural ventilation. This significantly reduces the safety hazards of high-rise window openings, avoids excessive wind resistance in high-rise buildings, and solves the problem of windows being unable to be opened during inclement weather.

[0025] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
