Description

Technical Field

[0001] This invention relates to a variable window-to-wall ratio enclosure structure with thermal insulation adjustment function. Specifically, it is a variable window-to-wall ratio enclosure structure that can significantly improve the thermal insulation performance of exterior windows by adjusting the window-to-wall ratio. Background Technology

[0002] Exterior windows are a weak link in the thermal insulation of building envelopes, with their insulation performance being only a fraction of that of exterior walls. Currently, most building exterior windows use energy-saving windows with single or double-cavity insulated glass and thermally broken profiles, with a heat transfer coefficient generally not less than 2.0 W / (m²). 2 (K). To further improve the thermal insulation performance of exterior windows, it is necessary to increase the number of glass layers and use better thermal insulation profiles. This significantly increases the cost, but the performance improvement is not significant, resulting in low cost-effectiveness and making it difficult for users to accept. Currently, some residents spontaneously use so-called thermal insulation curtains to keep warm in winter. These thermal insulation curtains are not real curtains, but rather roller blinds made of composite fabrics such as PVC (polyvinyl chloride) film, PEVA (polyethylene-vinyl acetate) film, or polyester fiber, which are slightly larger than the window opening. They are attached to the perimeter of the interior window opening with Velcro with adhesive backing, forming a closed air layer with the exterior window. This provides some insulation, but the improvement in thermal insulation performance is not significant. The thermal insulation curtains are fixed to the window opening and cannot be opened and closed flexibly as needed, which affects the normal use of the exterior window to some extent. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of existing technologies by providing a variable window-to-wall ratio enclosure structure with thermal insulation and regulation functions.

[0004] This invention is achieved through the following technical solution: a variable window-to-wall ratio enclosure structure with thermal insulation and adjustment function, including a window opening, upper and side walls of the window opening, lower wall of the window, an outer window, and a thermal insulation and adjustment device; The upper and side walls of the window opening and the lower wall of the window are equipped with an external insulation system on the outside and an internal plaster layer on the inside. The window opening is equipped with an exterior window, which is connected to the window opening by a subframe. Below the exterior window is a windowsill. The exterior window includes exterior window glass and exterior window profile. The aforementioned thermal insulation and adjustment device is installed on the inner side of the outer window at the window opening, including the window sill box side plate and three rows of cross-sections. The exterior window features a series of insulation panels, namely, a first row, a second row, and a third row. The window openings on both sides of the exterior window are equipped with a first row, a second row, and a third row of tracks, allowing the insulation panels to slide up and down along these tracks. Three pairs of retractable support plates are installed along the height of the window openings on both sides of the exterior window; these are the first pair, the second pair, and the third pair of support plates, used to support the first, second, and third rows of insulation panels respectively. A small crossbeam is installed in the upper window opening of the exterior window to constrain the first row of insulation panels and to cover the gap between the first row of insulation panels and the inner side of the exterior window. The working state of the variable window-to-wall ratio enclosure structure is divided into three states: the thermal insulation adjustment device is not activated, the thermal insulation adjustment device is partially activated, and the thermal insulation adjustment device is fully activated. When the insulation adjustment device is not activated, the first, second, and third rows of insulation boards are stacked in three rows inside the window sill box. The upper part of the cross-section insulation board covers the side panel of the window sill box; The thermal insulation adjustment device is activated as follows: the first row of thermal insulation boards is pulled out and lifted, slides along the first row track to the top, and the first pair of support plates are pressed to pop them out and support the first row of thermal insulation boards; the second row of thermal insulation boards is pulled out and lifted, slides along the second row track to a predetermined height, and the second pair of support plates are pressed to pop them out and support the second row of thermal insulation boards. The fully activated state of the thermal insulation adjustment device is as follows: the third row of thermal insulation boards is pulled out and lifted, slides along the third row track to a predetermined height, and the third pair of support plates are pressed to pop them out and support the third row of thermal insulation boards; the first row of thermal insulation boards, the second row of thermal insulation boards, and the third row of thermal insulation boards, together with the small horizontal beam on the window and the side panel of the window sill box, cover the window opening to form a combined enclosure structure with thermal insulation boards, a closed air layer, and an exterior window.

[0005] Preferably, the side panel of the windowsill box is made of materials with certain strength and thermal insulation properties, such as autoclaved aerated concrete panels.

[0006] Preferably, the cross-sections of the first row of insulation boards, the second row of insulation boards, and the third row of insulation boards are as follows: The insulation board is constructed using lightweight and efficient vacuum insulation panels, aerogel, expanded polyurethane foam, extruded polystyrene boards, and other insulation materials combined with protective materials such as plastics and aluminum plates. The lower end of the insulation board features a horizontally oriented soft-textured structure, while both ends of the insulation board have vertically oriented... The groove is shaped and has soft bristles.

[0007] Preferably, the first, second, and third rows of tracks are made of materials that are poor conductors of heat, such as wood and plastic, and have a rectangular cross-section. They are connected to the walls on both sides of the window opening by bonding, anchor bolts, nails, or other means.

[0008] Preferably, the small horizontal beam on the outer window is made of a material that is a poor conductor of heat, such as wood or plastic, and has a rectangular cross-section. The small horizontal beam is connected to the upper wall of the window opening by bonding, anchor bolts, nails, etc., and soft bristles are provided on the side of the small horizontal beam along the horizontal direction.

[0009] Preferably, the first pair of trays, the second pair of trays, and the third pair of trays are made of materials such as stainless steel and galvanized steel, and are placed in the sleeves set in the openings in the walls on both sides of the window opening.

[0010] The present invention has the following beneficial effects: 1) When the thermal insulation adjustment device is fully activated, the variable window-to-wall ratio enclosure structure forms a combined enclosure structure with insulation panels, a closed air layer, and exterior windows, which can increase the thermal resistance by 1.0–5.0 (m). 2 ·K) / W, improves the thermal insulation performance of exterior windows by 3-10 times, significantly improves the indoor thermal environment, and saves energy consumption for heating and air conditioning.

[0011] 2) When the insulation adjustment device is not activated, the insulation board is hidden inside the window sill box at the bottom of the window, saving space and not affecting the aesthetics.

It is not activated during the day when lighting is needed to ensure lighting and ventilation, and is activated at night or during the day when lighting is not needed to ensure thermal insulation.
