Description

Low energy consumption exposed frame curtain wall insulation structure Technical Field

The invention relates to a wall of a building, in particular to a curtain wall.

Background technique

The General Code for Energy Conservation and Renewable Energy Utilization in Buildings, numbered GB55015-2021, was officially implemented on April 1, 2022. The new code stipulates that the average design energy consumption level of newly built public buildings in my country should be reduced by 20% based on the energy-saving design standards implemented in 2016, that is, the average energy saving rate of public buildings should be 72%. Correspondingly, the heat transfer coefficient requirements of glass curtain walls have also been raised to an unprecedented level. Taking Beijing as an example, before April 1, 2022, the heat transfer coefficient of glass curtain walls of newly built public buildings is generally around 1.8W/(㎡·K); from April 1, 2022, the minimum heat transfer coefficient of glass curtain walls should not be higher than 1.3W/(㎡·K).

In order to meet the heat transfer coefficient requirements of glass curtain walls, the existing technology mainly relies on setting non-metallic materials with low thermal conductivity inside the aluminum alloy frame to play the role of thermal insulation and cold bridge. In summary, there are two types of technical solutions:

FIG1 shows a first type of technical solution, including an indoor metal keel 1′, an outdoor metal keel 2′, a three-glass two-cavity insulating glass 3′, and a nylon heat-insulating strip 4′ and an organic foam material 1 5′ installed therebetween. An organic foam material 2 6′ is arranged between the two nylon heat-insulating strips 4′, and an indoor sealing strip 7′ and an outdoor sealing strip 8′ are also arranged between the three-glass two-cavity insulating glass 3′ and the indoor and outdoor metal keels. The shortcomings of this solution are: in order to meet the heat transfer coefficient requirements of the low-energy curtain wall, the cross-sectional height of the nylon heat-insulating strip must be greatly increased, and in order to compensate for the air convection effect of the large cavity, this nylon heat-insulating strip must be used in combination with an organic foam material, which increases the construction cost and also implies safety risks such as poor compatibility, aging resistance and flammability of the material.

FIG2 shows the second technical solution, which is a utility model patent applied by the present applicant, named as high-efficiency heat insulation structure of exposed frame glass curtain wall, with authorization announcement number CN207392537U, comprising indoor metal keel 1", outdoor metal keel 2" and curtain wall glass 3" and nylon heat insulation strip 4" installed therebetween, the curtain wall glass 3" is fixed between outdoor metal keel 2" and indoor metal keel 1" through outdoor sealing strip 8" and indoor sealing strip 7", and a full-length heat insulation strip 9" made of aerogel heat insulation blanket is arranged between outdoor metal keel 2" and indoor metal keel 1" along the length direction of the metal keel. The disadvantage of this solution is that the heat transfer coefficient of the glass curtain wall of Example 1 is 1.95W/(㎡·K), and the heat transfer coefficient of the glass curtain wall of Example 3 is 1.83W/(㎡·K), both of which are higher than 1.3W/(㎡·K). Compared with the traditional solution, although the performance is improved, it still cannot meet the heat transfer coefficient requirement of low-energy consumption glass curtain wall.

Therefore, there is an urgent need for a low-energy consumption exposed frame glass curtain wall insulation structure that can meet the requirement that the curtain wall heat transfer coefficient is not higher than 1.3W/(㎡·K), has good insulation effect, safe and reliable structure, and low comprehensive cost.

Example 1

This embodiment shows the heat insulation structure of a frame-type exposed frame curtain wall.

As shown in Figs. 3 and 4, a through-length special heat insulation component limiting groove 1021 is provided in the middle of the press-fit surface of the aluminum alloy press plate 102 along its length direction; sealing component limiting grooves A1022 and B1022' are provided on the press-fit surface of the aluminum alloy press plate 102 and on both sides of the special heat insulation component limiting groove 1021.

As shown in Figs. 3 and 6, a full-length special heat insulation component limiting groove 2 1011 is provided in the middle of the connection surface of the aluminum alloy indoor frame 101 and at the corresponding position of the special heat insulation component limiting groove 1 1021; as shown in Figs. 3-6, a sealing component limiting groove 2 A1012 and B1012' are provided on the connection surface of the aluminum alloy indoor frame 101 and on both sides of the special heat insulation component limiting groove 2 1011. The depth L2 of the special heat insulation component limiting groove 1 1021 and the depth L1 of the special heat insulation component limiting groove 2 1011 are not less than 1 mm, and the net width T1 of the special heat insulation component limiting groove 1 1021 is equal to the net width T2 of the special heat insulation component limiting groove 2 1011, which are the same as the width T of the special heat insulation component. The space within the special heat insulation component limiting groove 1 1021 and the special heat insulation component limiting groove 2 1011 can just accommodate the special heat insulation component 105.

As shown in FIG. 5 , the special thermal insulation component 105 is composed of two layers of aerogel insulation blankets 1051 (of course, three or more layers of aerogel insulation blankets can also be used), wherein the thickness direction of each layer of aerogel insulation blanket 1051 is parallel to the inner surface of the hollow glass room, and the length direction of each layer of aerogel insulation blanket 1051 is perpendicular to the inner surface of the hollow glass room. The thickness of the two layers of aerogel insulation blankets 1051 after composite is used as the width T of the special thermal insulation component 105, and the width of the two layers of aerogel insulation blankets 1051 is used as the thickness W of the special thermal insulation component 105. The thickness W of the special thermal insulation component 105 is greater than or equal to its width T.

As shown in Figures 3 and 4, the special heat insulation component 105 is embedded in the special heat insulation component limiting groove 1 1021 and the special heat insulation component limiting groove 2 1011 and connected with the aluminum alloy pressure plate 102 and the aluminum alloy indoor frame 101 through the fastener 106; there are multiple fasteners 106, and the multiple fasteners 106 are arranged at intervals along the length direction of the special heat insulation component 105. In this embodiment, the fastener is a bolt. As shown in Figures 3 and 6, the middle part of the connecting surface of the aluminum alloy indoor frame 101 is also provided with a through-length fastener head receiving groove 1013 connected to the special heat insulation component limiting groove 2 1011, and the fastener head receiving groove 1013 is used to accommodate the bolt head and ensure that there is enough operating space when installing the bolt.

As shown in FIG. 3 , the insulating glass 103 is inserted into a groove-shaped space formed by the aluminum alloy pressing plate 102 , the aluminum alloy indoor frame 101 and the special heat insulation component 105 and fixed.

As shown in Figure 3, the first seal A107 and the first seal B107' are filled and sealed at the joint between the aluminum alloy pressure plate 102 and the insulating glass 103; the second seal A108 and the second seal B108' are filled and sealed at the joint between the insulating glass 103 and the special insulation component 105; the third seal A109 and the third seal B109' are filled and sealed at the joint between the aluminum alloy indoor frame 101 and the insulating glass 103.

As shown in FIG. 3 , the insulating glass 103 has three layers, that is, three-glass two-cavity insulating glass is adopted, and a warm edge spacer 1031 is arranged between two adjacent layers of glass.

As shown in Fig. 16, the heat transfer coefficient U value of the frame in Example 1 is 1.3933 W/(㎡·K). The heat transfer coefficient of the three-glass two-cavity insulating glass 103 in Example 1 is 0.70 W/(㎡·K).

According to the calculation of the curtain wall grid with a width * height of 1.2 meters * 2.5 meters, when the heat transfer coefficient of the insulating glass is 0.70W/(㎡·K), the heat transfer coefficient of the curtain wall of Example 1 is 0.95W/(㎡·K), which can meet the requirement that the heat transfer coefficient of the low-energy consumption glass curtain wall is not higher than 1.3W/(㎡·K), and has reached the standard that the heat transfer coefficient of the ultra-low energy consumption glass curtain wall is not higher than 1.0W/(㎡·K).

Of course, this embodiment can also be matched with glass with other heat transfer coefficients. For example, if the curtain wall grid is calculated according to the same width * height of 1.2 meters * 2.5 meters, when the insulating glass with a heat transfer coefficient of 1.04W/(㎡·K) is matched, the heat transfer coefficient of the curtain wall in Example 1 is 1.26W/(㎡·K), which can still meet the requirement that the heat transfer coefficient of the low-energy glass curtain wall is not higher than 1.3W/(㎡·K).

As shown in FIG7 , the insulating glass 203 is inserted into the groove-shaped space formed by the aluminum alloy pressure plate 202, the aluminum alloy interior frame 201 and the special thermal insulation component 205 and fixed; the insulating glass 203' is inserted into the groove-shaped space formed by the aluminum alloy pressure plate 202', the aluminum alloy interior frame 201' and the special thermal insulation component 205' and fixed.

As shown in FIG. 7 , the insulating glass 203 has three layers, that is, three-glass two-cavity insulating glass is adopted, and a warm edge spacer 2031 is arranged between two adjacent layers of glass.

As shown in Fig. 17, the heat transfer coefficient U value of the frame of Example 2 is 1.5414 W/(㎡·K). In Example 2, a three-glass two-cavity insulating glass 3 with a heat transfer coefficient of 0.70 W/(㎡·K) is also used.

According to the calculation of the curtain wall grid with a width * height of 1.2 meters * 2.5 meters, when the glass with a heat transfer coefficient of 0.70W/(㎡·K) is matched, the heat transfer coefficient of the curtain wall of Example 2 is 1.00W/(㎡·K). This embodiment can meet the requirement that the heat transfer coefficient of the low-energy consumption glass curtain wall is not higher than 1.3W/(㎡·K), and has reached the standard that the heat transfer coefficient of the ultra-low energy consumption glass curtain wall is not higher than 1.0W/(㎡·K).

Of course, this embodiment can also be matched with glass with other heat transfer coefficients. For example, if the calculation is performed according to the curtain wall grid with a width * height of 1.2 meters * 2.5 meters, when the glass with a heat transfer coefficient of 1.04W/(㎡·K) is matched, the heat transfer coefficient of the curtain wall of Example 2 is 1.30W/(㎡·K), which can still meet the requirement that the heat transfer coefficient of the low-energy glass curtain wall is not higher than 1.3W/(㎡·K).

In the present invention, the special insulation component is composed of two or more layers of aerogel insulation blankets, and is an overall moisture-proof, waterproof and fireproof insulation component. In the prior art solution, the thickness of the aerogel insulation blankets constituting the insulation strip is superimposed as the thickness of the insulation strip; while in the low-energy consumption exposed frame curtain wall insulation structure of the present invention, the thickness of the two or more layers of aerogel insulation blankets after being composited is used as the width T' of the special insulation component one, and the width of the two or more layers of aerogel insulation blankets is used as the thickness W' of the special insulation component one; the thickness of the two or more layers of aerogel insulation blankets after being composited is used as the width T", of the special insulation component two, and the width of the two or more layers of aerogel insulation blankets is used as the thickness W", of the special insulation component two. Under the premise that the size of the insulation strip is the same as that of the special insulation component, the present invention reduces the number of cut sections, reduces the amount of adhesive used on the bonding surface between multiple layers of aerogel insulation blankets, further saves construction costs, and improves the fire resistance and aging resistance of the special insulation component. Through research, it can be determined that under the application state of the present invention, the design value of the thermal conductivity of the special thermal insulation component is 0.04W/(m·K), and the compression deformation under the design external force is no more than 1%.

Based on the above, the present invention has the following beneficial effects:

1. It can meet the requirement that the heat transfer coefficient of the curtain wall is not higher than 1.3W/(㎡·K), with good thermal insulation effect and low energy consumption: The special thermal insulation components, various seals, hollow glass and warm edge spacers in the present invention form a continuous heat barrier between the outdoor aluminum alloy pressure plate and the indoor aluminum alloy indoor frame, reducing the transfer of heat. It can be seen from the above-mentioned U value calculation and analysis that the present invention can meet the requirement that the heat transfer coefficient of the curtain wall is not higher than 1.3W/(㎡·K), with good thermal insulation effect and low energy consumption.

2. The structure is safe and reliable, the construction process is convenient, and the overall cost is low: In the present invention, the special thermal insulation component is connected to the aluminum alloy pressure plate and the aluminum alloy indoor frame by fasteners such as bolts or screws, and the special thermal insulation component is embedded in the special thermal insulation component limiting groove 1 and the special thermal insulation component limiting groove 2 and fixed by fasteners, and the structure is safe and reliable; in the existing technical scheme, a variety of equipment is required to connect the thermal insulation strip with the curtain wall frame. Taking the most commonly used strip-through thermal insulation strip shown in Figures 1 and 2 as an example, at least three special equipments, namely, a gear opening machine, a strip-through machine and a rolling machine, are required. The process is very complicated and the fault tolerance rate is low. In addition, if the construction process is not properly controlled, it is likely to cause quality and safety problems such as failure of the thermal insulation strip; in the present invention, the fixing method of the special thermal insulation component adopts mechanical fixing such as bolts or screws, the construction process is convenient, and no special equipment is required in the construction process. The construction can be completed in the factory or on the construction site, and the construction cost is low, and the overall cost is reduced.

In the low-energy consumption exposed frame curtain wall insulation structure of the present invention, the thickness of two or more layers of aerogel insulation blanket after compounding is used as the width of the special insulation component, the width of special insulation components one and two, and the width of two or more layers of aerogel insulation blanket is used as the thickness of the special insulation component, the thickness of special insulation component one, and the thickness of special insulation component two, thereby reducing the number of cut sections, reducing the amount of adhesive used on the bonding surface between multiple layers of aerogel insulation blankets, and further saving construction costs.

3. High processing precision: In the prior art solutions, when multiple layers of aerogel insulation blankets are needed, they are stacked in the thickness direction. However, since the surface of the aerogel insulation blanket is not completely flat and the thickness usually has a positive tolerance of about 1 mm, the thickness error will gradually accumulate after stacking in the thickness direction, resulting in poor overall thickness accuracy of the multiple layers of aerogel insulation blankets. In the present invention, although the special thermal insulation component is essentially a multi-layer aerogel insulation blanket, the width of the multi-layer aerogel insulation blanket is used as the thickness of the special thermal insulation component with high precision control requirements, and the thickness of the multi-layer aerogel insulation blanket is used as the width of the special thermal insulation component, which reduces error accumulation, has high processing precision, and the error of the width of the special thermal insulation component can be absorbed by the limiting groove of the special thermal insulation component.

4. Reduced dust, improved waterproofness, improved fire resistance, and safe use: Taking the example of using a 10mm thick aerogel insulation blanket to make a multi-layer aerogel insulation blanket with a width of 20mm and a height of 40mm, the existing technical solution adopts the method of stacking in the thickness direction, and a total of 4 aerogel insulation blankets with a width of 20mm and a thickness of 10mm need to be cut out, with at least 8 cut sections. Since the aerogel insulation blanket inevitably carries dust, the amount of dust on the cut section is more than that on the large surface, and the waterproofness of the cut section is slightly worse than that on the large surface, so reducing the cut section can effectively reduce dust and improve the waterproofness of the multi-layer aerogel insulation blanket. The special heat insulation assembly of the present invention only needs to cut out two aerogel heat insulation blankets with a width of 40 mm and a thickness of 10 mm during production, with only four cut sections, and these cut sections are completely fitted with the aluminum alloy pressing plate and the aluminum alloy indoor frame, respectively, thereby reducing dust during the construction process, and also greatly reducing dust caused by wind shock of the building in the future, and improving the waterproofness of the special heat insulation assembly. In addition, during production, the plane where the width and length of the special heat insulation assembly of the present invention are located is exposed, and various surface treatments can be performed on it as needed.

In the low-energy consumption exposed frame curtain wall insulation structure of the present invention, since the amount of adhesive used on the bonding surface between multiple layers of aerogel insulation blankets is reduced, the fire resistance and aging resistance of the special insulation component are improved, the fireproof performance is improved, and the use is safer.

5. In addition, the present invention also has certain social value: Taking Beijing as an example, assuming an office building with a curtain wall area of 20,000 square meters, using the thermal insulation structure of the present invention, the heat transfer coefficient of the curtain wall can be reduced from the original 1.8W/(㎡·K) to 1.3W/(㎡·K), then the heat loss through the curtain wall can be reduced by at least 360,000 kWh per year. According to the design life of the curtain wall of 25 years, 9 million kWh of electricity can be saved in the entire life cycle, which is equivalent to 11,000 tons of standard coal. According to the "2021-2022 China Door and Window Curtain Wall Industry Research and Development Analysis Report" provided by the Aluminum Door and Window Curtain Wall Branch of the China Building Metal Structure Association, the output value of my country's curtain walls in 2021 was more than 120 billion yuan, which is equivalent to a curtain wall area of about 80 million square meters. Assuming that 20% of the engineering projects use the thermal insulation structure of the present invention, it can save 8.8 million tons of standard coal for my country, which has certain social value.

The embodiments described above are merely descriptions of preferred implementation modes of the present invention and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should all fall within the protection scope determined by the claims of the present invention.
