Description

Technical Field

[0001] This invention relates to the field of building energy-saving decoration, specifically a method for sun protection of doors and windows installed on the exterior facade of a building. Background Technology

[0002] Currently used methods for preventing indoor sun exposure, especially for west-facing windows in high-rise buildings, mostly involve hanging various types of curtains, both soft and hard. However, regardless of the type, any device hung indoors, while offering some relief from solar radiation, cannot prevent the accumulation of heat that has already penetrated the glass and caused indoor temperature rise. This is especially problematic in summer, forcing users to increase air conditioning cooling levels, thus increasing energy consumption. Even more frustrating is that the laminated glass in thermally broken windows is subjected to high temperatures during the day and low temperatures at night. In this large temperature difference, the air in the glass interlayer undergoes alternating condensation and evaporation, easily leading to fogging. Once fog forms, the glass will permanently lose its brightness, and repair is virtually impossible except by replacing the glass. Furthermore, while various soft or hard awnings installed on the tops of windows offer some protection against the sun at midday, these structures are ill-suited to withstand the unpredictable wind and rain, especially in high-rise buildings. Sudden strong winds are often the bane of these awnings, leading to falling objects and even personal injury. Moreover, for west-facing windows in high-rise buildings, the afternoon sun streams in almost horizontally, rendering awnings at the top of the window virtually ineffective. Useless and risky, this is the unfortunate situation. Summary of the Invention

[0003] To address the aforementioned problems, this invention discloses a method for sun protection of doors and windows installed on the exterior facade of buildings. It primarily aims to solve the sun protection problem for doors and windows in high-rise buildings, especially those facing west, and falls within the field of building energy conservation and decoration. The core of its implementation is to effectively control all three modes of heat transfer—heat radiation, heat conduction, and heat convection—to block heat originating from the building's exterior from reaching the outside.

[0005] The present invention will now be described in detail with reference to the accompanying drawings.

[0006] like Figure 2 As shown, a method for sun protection of doors and windows installed on the exterior of a building involves connecting two or more parallel arrays of reflective heat-insulating panels (12) to a base positioning frame (1) at the door / window location on the exterior of the building via a perpendicular connection between the array plane and three or more support rods (6) of predetermined length. This ensures that the array plane of the parallel array of reflective heat-insulating panels (12) maintains a predetermined distance from the exterior of the building that allows for free airflow. The purpose of this embodiment is to block solar and thermal radiation from outside the building while simultaneously dissipating the heat absorbed by the parallel array of reflective heat-insulating panels 12 to the outside in a timely manner.

[0007] like Figure 2 As shown, a method for sun protection of doors and windows installed on the exterior facade of a building is described. The basic positioning frame (1) is composed of four rods of the same specifications. The four rods are parallel to the opposite support and perpendicular to the adjacent support. The four rods are connected in a rectangular shape by right-angle connectors (3) and are all connected by screws. The rods connected in a rectangular shape are then installed in the door and window positions close to the exterior wall of the building using expansion bolts (2). This ensures that the four rods of the basic positioning frame (1) are parallel to the four sides of the building door and window openings, and the distance between the four rods of the basic positioning frame (1) and the four sides of the building door and window openings does not exceed the specified position that can be reached by the back of the installer's hand and the length of the tool.

[0008] like Figure 2 As shown, a method for sun protection of doors and windows installed on the exterior of a building involves connecting the ends of four or more support rods (6) to the intersection of four rod-shaped objects of the base positioning frame (1) using right-angle connectors (4) and (5) during the installation process, so that the four or more support rods (6) are perpendicular to the rectangular plane of the base positioning frame (1).

[0009] like Figure 2 As shown, a method for sun protection of doors and windows installed on the exterior facade of a building involves installing the multi-axis slotted rods (7) and (8) horizontally or vertically onto two of the tail ends of four or more support rods (6) using the right-angle connectors (9).

[0010] like Figure 2 As shown, a method for sun protection of doors and windows installed on the exterior of a building involves cutting the reflective heat insulation panels (12) of the parallel array to a predetermined thickness according to the size of the doors and windows and installing them in the grooves of the U-shaped slots (10) and (11) to form a heat insulation panel array combination of adjacent panels.

[0011] like Figure 2As shown, a method for sun protection of doors and windows installed on the exterior of a building is described. The central shaft (19) set outside the bottom of the U-shaped slots (10) and 11 is installed in the shaft holes of the multi-axis slot rods (7) and (8) respectively through bushings (13) and (14), so that it can rotate around the shaft hole as the center, thereby controlling the light flux.

[0012] like Figure 5 As shown, a method for sun protection of doors and windows installed on the exterior of a building is described. The multi-axis hole linkage rod (16) is a strip with a predetermined thickness and four sides. One of the long sides is a straight side, and the other long side opposite to this side is made up of alternating protrusions and recesses on the same plane. The multi-axis hole linkage rod (16) is connected to the secondary shaft (20) through a bushing, so that the rotation of each reflective heat insulation plate (12) can be synchronized.

[0013] like Figure 5 As shown, a method for sun protection of doors and windows installed on the exterior facade of a building is provided. In order to facilitate the control of light flux, a handle (18) is installed at an off-center position on a U-shaped slot (10) or (11) that is closest to the original window position of the building.

[0014] like Figure 3 As shown, a method for sun protection of doors and windows installed on the exterior of a building includes a clamping and locking device (17) installed in the groove of the multi-axis hole rod (7) or (8) for manually clamping and locking the central axis (19) to prevent the reflective heat insulation strip (12) from uncontrollably flipping under the action of wind.

[0015] like Figure 4 As shown, a window and door sun protection device installed on the exterior of a building has each of the reflective heat insulation panels (12) having a heat insulation material in the middle layer and a covering layer with light reflection or light absorption function on the outside.
