Description

Technical Field

[0001] The utility model relates to the technical field of construction, in particular to a heat-insulating and sun-shading system in a glass curtain wall. Background Art

[0002] Modern buildings, especially large office buildings, maximize sunlight to improve the indoor environment, often using large windows or even glass curtain walls. Northern my country, located in a typical continental climate zone, places high demands on winter heating. However, the high energy consumption of winter heating and the corresponding high costs of construction and equipment require that buildings themselves adapt to climate changes and achieve resilience through the building's exterior.

[0003] Current research shows that the amount of solar radiation entering a room through glass is more than 30 times that of walls, which makes the room temperature higher in summer and causes high electricity consumption for cooling in summer; if certain shading measures are taken, the amount of heat passing through will be significantly reduced, accounting for about 1 / 3 of the original amount; on the other hand, the thermal insulation effect of large windows and glass curtain walls on the walls is not as good as that of the building's enclosing walls, resulting in poor thermal insulation effect of the entire building in winter.

[0004] In the prior art, the effect of reducing solar radiation is generally achieved by installing sunshade devices on external windows of buildings; among them, movable external sunshade venetian blinds are the most widely used movable external sunshade systems. However, since the current venetian blinds use ladder ropes to control the inclination of the blinds, the degree of closure between the blinds is not enough when the blinds are in the sunshade position, and the blinds' rotation angle is generally between 65°-70°, there is still a lot of scattered sunlight entering the room, and the shielding effect is poor and difficult to adjust, which reduces the cooling effect of the indoor air conditioner. On the other hand, the thermal insulation effect of large-area windows and glass curtain walls on the wall is not as good as that of the building's enclosing walls, resulting in poor thermal insulation effect of the entire building in winter. In the prior art, most of the thermal insulation and light-transmitting roller shutter systems are used to improve the thermal insulation of existing doors and windows. Ordinary glass curtain walls have poor thermal insulation performance, which greatly increases the energy consumption of the building. Utility Model Content

The specific embodiments described here are only used to explain the present invention and are not intended to limit the present invention.

[0035] Specific implementation method 1: Combination Figures 1 to 15 To describe this embodiment, a heat-insulating and sun-shading system in a glass curtain wall is described in this embodiment, comprising a power assembly 1, a guide rail assembly 2, a pulley assembly 4 and a heat-insulating and sun-shading assembly 5; the power assembly 1 is installed on a building 9, the guide rail assembly 2 is conformally arranged on the inner side of the glass curtain wall of the building 9, one end of the heat-insulating and sun-shading assembly 5 is wound around the power assembly 1, and the other end is slidably connected to the guide rail assembly 2 through the pulley assembly 4.

[0038] In this embodiment, the number of power assemblies 1 is set according to the width of the glass curtain wall. A single-axis power assembly, i.e., a system consisting of a reel and a shaft tube, has a torque of no less than 140 N·m for the active reel, a shaft tube length no greater than 10 meters, and a shaft tube diameter no less than 100 mm. Each active reel 11 has at least one reel motor. If the active reel 11 exceeds 10 meters in length, two reel motors can be installed.

[0040] Other components and connection relationships are the same as those in the first embodiment.

[0041] Specific implementation method three: Combination Figures 1 to 15 To illustrate this embodiment, in this embodiment, the guide track assembly 2 is arranged on the curtain wall steel frame 8 of the glass curtain wall of the building 9, and the guide track assembly 2 includes a section of special-shaped track 21 and a guide flare 22. The left and right ends of the special-shaped track 21 away from the curtain wall steel frame 8 are respectively provided with arc-shaped pulley guide rails 23, and the left and right ends of the guide flare 22 are provided with obtuse-angled openings.

[0042] The track assembly used in this embodiment consists of a special-shaped track and a guide flare.

[0043] Track Installation: Drill holes on the back of the track and connect it to the curtain wall steel frame using L-shaped hangers. The track shape should conform to the curtain wall steel frame and be connected using bolts or drill nails. The curtain wall steel frame serves as the structural framework, and the bolts or drill nails serve as load-bearing anchor points. If the curtain wall lacks a steel frame, the track must be made of larger cross-section steel as the load-bearing track. In this case, the track serves as both a guide rail and a load-bearing function. Reinforcement ribs 24 are required within the special-shaped track 21.

[0044] Other components and connection relationships are the same as those in the first embodiment.

[0046] The pulley assembly used in this embodiment is composed of multiple groups of hanging wheels connected into one group through horizontal cross bars. The cross bars between the hanging wheels are provided with arc-shaped protrusions, which can effectively prevent the hanging wheels from piercing the soft curtain.

[0047] Other components and connection relationships are the same as those in the first embodiment.

[0048] Specific implementation method five: Combination Figures 1 to 15 To illustrate this embodiment, in this embodiment, the heat-insulating sunshade assembly 5 is a roller blind, which is wound on a metal shaft tube 12. The roller blind includes a heat-insulating protective layer 51, a thermal insulation layer 52 and an adhesive layer 53; the heat-insulating protective layer 51, the thermal insulation layer 52 and the adhesive layer 53 are arranged in sequence from the outside to the inside, and the cross bar 41 is arranged on the heat-insulating protective layer 51.

[0049] In this embodiment, the heat-insulating protective layer 51 is made of aluminum foil, and the thermal insulation layer 52 is made of multiple pieces. The heat-insulating sunshade assembly 5 comprises a mechanical system consisting of a power source, tracks, supports, and pulleys, enabling lifting and retracting of the reel. Chemicals or textiles with heat-insulating and sun-shading properties can be mounted on the crossbars of the pulley assembly.

[0050] When the insulation layer 52 is made of a relatively hard material such as foam or rubber, the crossbar can be connected and fixed to the hard material with a high-temperature material such as nylon bolts. When the insulation layer 52 is made of a soft material such as honeycomb curtains or UV-resistant aging cloth, a counterweight crossbar needs to be installed at the bottom edge of the entire curtain.

[0053] The guide bracket assembly 3 used in this embodiment is composed of a telescopic fine-tuning bracket and a shuttle-shaped roller. The roller is positioned by the adjustable bracket and works in conjunction with the guide flare 22 of the track assembly to ensure that the hanging wheel in the pulley assembly can stably enter and exit the track.

[0054] Other components and connection relationships are the same as those in the first embodiment.

[0056] This embodiment of the retractable thermal insulation curtain utilizes a conventional structure that achieves thermal insulation, preferably consisting of a horizontal bar mount, multiple sets of motorized arms, a retractable horizontal bar, and an outer curtain fabric. When the inner curtain is closed, the retractable thermal insulation curtain arms extend, and the outer curtain fabric adheres to the roller shaft. Before the inner curtain is opened, the retractable thermal insulation curtain arms are retracted, causing the outer curtain fabric to retract and move away from the roller shaft.

[0057] Other components and connection relationships are the same as those in the first embodiment.

[0058] Specific implementation method eight: combination Figures 1 to 15 To illustrate this embodiment, the heat insulation and shading system in this embodiment also includes a sealing bracket assembly 7, which is arranged at the intersection of the roller shutter and the double-side gables of the glass curtain wall.
