However, the description of these examples is not intended to limit the scope of the present application in any way. According to specific application scenarios and requirements, these values or value ranges can be set otherwise.
[0028] As described above, the prior art urgently needs a low-cost and operable glass curtain wall reconstruction method to meet the current requirements for the heat preservation and insulation performance of the glass curtain wall. The glass curtain wall insulation reconstruction structure proposed in the embodiments of the present application at least partially solves the above problems. The structure and working principle of the glass curtain wall insulation reconstruction structure according to the example embodiments of the present application will be described below with reference to Figure 1 and Figure 2 The glass curtain wall reconstruction structure of the embodiments of the present application mainly includes a stand column 1, a cross beam 8, a curtain wall glass 4, an insulation glass 5, a partition strip 6, a pressing strip 2, a buckle cover 3, and a decorative strip. The stand column 1 and the cross beam 8 form a frame of the glass curtain wall. The cross beam 8 and the stand column 1 have basically the same cross-sectional structure. The cross beam 8 and the stand column 1 are connected with the pressing strip 2 at the outdoor side to form a mounting groove. The curtain wall glass 4 is placed in the mounting groove and is clamped by the cross beam 8, the stand column 1, and the pressing strip 2. The buckle cover 3 is installed at the outdoor side of the pressing strip 2. The insulation glass 5 is adhesively connected at the indoor side of the curtain wall glass 4. The partition strip 6 is arranged between the insulation glass 5 and the curtain wall glass 4. The decorative strip is arranged at the interface between the insulation glass 5 and the stand column 1 and the cross beam 8, and is used to realize the decoration and sealing effects. Exemplarily, the curtain wall glass 4 can be a double-layer hollow glass 4 as shown in Figure 1 and Figure 2
[0029] As Figure 1 and 2 As shown, since the original curtain wall glass 4 is placed in the mounting groove, there is no space in the mounting groove to place the heat-insulating glass 5. Furthermore, to ensure that the cavity formed between the heat-insulating glass 5 and the curtain wall glass 4 has sufficient thickness to achieve the required thermal insulation effect, this embodiment of the invention at least aligns the outer edge of the heat-insulating glass 5 with the profile sidewall of the column 1. This arrangement also ensures that the structural adhesive 7 between the profile and the heat-insulating glass 5 provides sufficient structural strength. The heat-insulating glass 5 in this embodiment of the invention is made of conventional glass components with heat-insulating functions, and has a better heat insulation effect than ordinary glass.
[0030] To form a cavity, a spacer 6 is installed between the heat-insulating glass 5 and the curtain wall glass 4. The spacer 6 surrounds the outer edge of the glass to form a closed cavity, keeping the inside and outside of the cavity isolated and sealed in terms of temperature and humidity. In one embodiment, to improve the temperature and humidity isolation and sealing effect of the spacer 6, the main body of the spacer 6 is made of silicone foam. The silicone foam has a microporous structure, which on the one hand gives the silicone foam sufficient elastic deformation capacity to ensure the temperature and humidity isolation and sealing effect inside and outside the cavity from the structural dimensions; on the other hand, molecular sieves are pre-installed in the microporous structure, thereby playing a drying role in the environment inside the cavity.
[0031] The spacer 6 can be a conventional molecular sieve spacer 6, i.e., a molecular sieve pre-filled with an aluminum strip. In one embodiment, the spacer 6 can be made of silicone foam with a microporous structure inside. The microporous structure provides sufficient compressive elastic deformation of the silicone foam, thereby enabling the spacer 6 to be used in cavities of different thicknesses and to maintain sufficient temperature and humidity isolation and sealing. On the other hand, the microporous structure can be used to pre-fill the molecular sieve, thereby providing a moisture-proof effect to the cavity.
[0032] In one embodiment, the spacer 6 can be square or T-shaped, with the wide side of the T-shaped spacer facing the cavity and the narrow side facing the outer edge of the glass. PIB butyl rubber is filled on both sides of the narrow side to further improve the sealing performance of the spacer 6.
[0033] In one embodiment, the outer edge of the heat-insulating glass 5, the frame, the spacer 6, and the curtain wall glass 4 together form a gap, and structural adhesive 7 fills the gap, thereby adhesively bonding the heat-insulating glass 5 to the interior surface of the curtain wall glass 4. Since the gap is formed by the outer edge of the heat-insulating glass 5, the frame, the spacer 6, and the curtain wall glass 4 together, the structural adhesive 7 filling the gap is in contact and bonded to the outer edge of the heat-insulating glass 5, the frame, the spacer 6, and the curtain wall glass 4, thereby improving the bonding strength of the heat-insulating glass 5.
[0034] In one embodiment, since there is a gap between the heat-insulating glass 5 and the side wall of the profile, a decorative strip is provided on the indoor side of the gap to improve the aesthetics when observing from inside. The two sides of the decorative strip are respectively attached to the frame and the heat-insulating glass 5, thereby sealing the gap.
[0035] In one embodiment, the decorative strip is a square tube 9, which is glued to the frame using adhesive 10. In another embodiment, the decorative strip is a buckle 12 and a base 13, with the base 13 connected to the frame and the buckle 12 and base 13 snap-fitted together, making the installation of the decorative strip convenient and secure. For example, the base 13 is connected to the frame using screws.
[0036] In one embodiment, adhesive strips 11 are provided on both the frame and the pressure strip 2, and the frame and the pressure strip 2 are pressed against the surface of the curtain wall glass 4 by the adhesive strips 11.
[0037] In one embodiment, structural adhesive 7 is bonded to adhesive strip 11 of the frame.
[0038] According to the embodiments of this utility model, the entire renovation project can be completed simply by bonding the heat-insulating glass 5 to the interior surface of the curtain wall glass 4 on the existing glass curtain wall of the building, and by setting a closed spacer 6 between the heat-insulating glass 5 and the curtain wall glass 4. The renovation process is convenient and low in cost. The spacer 6 forms a closed space along the outer edge of the heat-insulating glass 5, adding a temperature transfer barrier to the interior side of the existing curtain wall glass 4 of the building. The spacer 6 is used to improve the sealing of the temperature transfer barrier, thereby improving the thermal insulation performance of the glass curtain wall and making the renovated glass curtain wall structure meet the current requirements.
