Detailed ways

Embodiment one:

This embodiment is an opening structure of an open frame aluminum alloy glass curtain wall heat insulation break bridge, as shown in Figures 1 and 2, Figure 1 is the state of the opening structure being opened, and Figure 2 is the state of the opening structure being closed, Also included in Fig. 2 is the opening handle 4 installed on the opening structure and the window lock 3 connected to the handle, for the sake of clarity, the handle and the window lock are omitted in Fig. 1 . In Figures 1 and 2, the left side of the opening frame and the opening fan is expressed as indoor, and the right side of the opening frame and opening fan is expressed as outdoor. Figures 1 and 2 show the cross-sectional views of door and window frames, and other figures are also cross-sectional views. According to the customary drawing method of the industry, the section of the profile is not marked with hatching. This embodiment includes: an opening frame 2 and an opening fan 1. The opening frame includes: a fixed inner frame 21 facing indoors, the fixed inner frame is connected with a fixed heat insulation frame 22, and the fixed heat insulation frame is connected with the The outdoor fixed outer frame 23 is connected. The opening fan includes: a fan inner frame 11 facing indoors, the fan inner frame is connected with a fan heat insulation frame 12, and the fan heat insulation frame is connected with a fan outer frame 13 facing outdoors. The frame plane of the fixed heat insulation frame coincides or nearly coincides with the frame plane of the fan heat insulation frame. The inner frame of the fan is bonded to the inner glass 16 of the double-glazed glass through the glass sealing strip 18, and the outer frame of the fan is bonded to the part of the outer glass of the double-glazed glass extending out of the glass frame 17 through the glass sealant 14. catch.

The opening structure described in this embodiment is an opening structure that can be used for casement doors and windows or hanging windows. The opening frame can be considered as a door frame or window frame in the usual sense, and the opening fan can be considered as a door frame in the usual sense. Door leaf or window leaf. The opening frame is mainly composed of profiles, and the opening fan is mainly composed of profiles and insulating glass. Insulating glass is a commonly used double-layer glass with a glass frame in the middle. The size of the outer glass of the insulating glass described in this embodiment is larger than that of the inner glass, and the extended part of the outer glass is bonded to the window frame. If the window frame is completely made of aluminum alloy profiles, there is no heat insulation link between the outer glass and the window frame, and heat can be freely transferred between the outer glass and the inner window frame, that is, there is heat exchange between indoors and outdoors , which is known in the industry as a "cold bridge". This cold bridge phenomenon also occurs on door frames and window frames made entirely of aluminum alloy profiles. In order to avoid the occurrence of cold bridges, a heat insulation frame made of non-thermally conductive material is set, an inner frame is set on the indoor side of the heat insulation frame, and an outer frame is set on the outdoor side of the heat insulation frame. Specific to this embodiment, it is called: fixed outer frame, fixed heat insulation frame, fixed inner frame; fan inner frame, fan heat insulation frame, fan outer frame. According to the principle of heat preservation, the heat insulation link is kept on a plane, which can effectively improve the heat insulation efficiency. In the industry, isotherms are used to represent the indoor and outdoor temperature changes of glass curtain walls. The said isotherm refers to the line formed by the same temperature points on different temperature gradients in the temperature field from indoor to outdoor. If the isotherm is straight, a good heat preservation effect can be produced, that is, the aforementioned heat insulation links are on one plane. The straight isotherm can effectively improve the insulation effect and reduce the K value (heat transfer coefficient). In order to achieve this effect in this embodiment, the frame plane of the fixed heat insulation frame and the frame plane of the fan heat insulation frame are designed on the same plane, that is, the aforementioned two planes coincide or nearly coincide. The frame plane mentioned here can be regarded as a "frame" formed by the closure of long strips of materials in a plane, and the plane formed by the part surrounded by the middle of the frame is the frame plane. Because, as architectural elements such as doors and windows, they are usually planes, or curved surfaces with a large radius of curvature close to the plane, so it can be directly considered that the surface surrounded by the frame of the door or window is a plane.

Another feature described in this embodiment is that the memory glass of the opening fan is bonded to the inner frame of the fan, while the outer layer of glass is bonded to the outer frame of the fan that is insulated by the heat insulating frame of the fan, so as to ensure that the heat insulating frame of the fan It is on the same plane with the fixed frame, and at the same time, it ensures that there is no cold bridge from the outer glass to the inner frame of the fan, and at the same time ensures the sealing and installation strength of the glass installation.

In this embodiment, multiple seals can also be provided to ensure the sealing performance of the opening structure. For example, an elastic sealing ring is set at a position parallel to the heat insulation frame of the opening fan, which cooperates with the fixed heat insulation frame on the opening frame to form the main sealing strip, and at the same time, the waterproof sealing strip and the dustproof sealing strip are arranged in the fixed frame and the fan On the frame, the dustproof sealing strip is arranged on the indoor side of the fixed frame and the fan inner frame, and the waterproof sealing strip is arranged on the outdoor side of the fixed frame and the fan inner frame. Such three-layer sealing strips can effectively use three-layer sealing, which can effectively improve the occurrence of easy air leakage and water leakage at the opening fan, and improve the watertight and airtight performance of the curtain wall.

In this embodiment, since the fixed heat insulation frame and the fan heat insulation frame are in the same plane, the outer layer of glass has a part extending outward than the inner layer of glass. The outer layer of glass is coincident with the plane facing the outside. In appearance, the outer frame of the opening fan is completely hidden, which makes the opening fan and the curtain wall more harmonious as a whole.

In order to facilitate the installation of various hardware in this embodiment, C-shaped grooves are arranged on the outside of the inner frame surrounding the fan, that is, on the surface opposite to the fixed inner frame, and hardware limiters are arranged on the positions of some pairs of C-shaped grooves in the fixed frame. The location is more convenient and faster for hardware installation. The C-shaped groove is a groove with a rectangular cross section, and protrusions are provided on both sides of the upper edge of the groove to restrict the metal parts inserted into the groove from sliding out of the groove.

In this embodiment, the processing method of partially thickening the profiles is adopted in the hardware assembly of the opening frame and the opening fan, which can further increase the firmness of the installation of the opening fan and reduce the risk of the fan falling off. The specific method is: thicken the bottom back of the C-shaped groove of the fan inner frame, and the thickened position on the fixed inner frame is arranged on the back of the opposite surface with the C-shaped groove, and the thickened shape can be a trapezoidal protrusion.
