[0038] In order to illustrate the technical solution provided by the present application, a detailed description is given below in conjunction with specific drawings and embodiments.

[0039] Some embodiments of the present application provide a renovated building, specifically a renovated building with better thermal insulation and heat preservation performance obtained by renovating a glass curtain wall building without destroying the existing structure of the glass curtain wall building.

[0040] See also Figure 1 , Figure 5The renovated building includes at least three vertically arranged first walls 10 and at least one vertically arranged second wall 20 .

[0041] Among them, each first wall 10 is connected end to end in sequence along the circumferential direction, at least one first wall 10 is a glass curtain wall 11, the second wall 20 is arranged on the inner side of the glass curtain wall 11, the second wall 20 is provided with at least one light opening 21 for light to penetrate, and the inner side of the second wall 20 is provided with a first insulation layer 22.

[0042] The number of second walls 20 is equal to the number of glass curtain walls 11, and a second wall 20 is correspondingly arranged on the inner side of each glass curtain wall 11. Based on this, by arranging the second wall 20 on the inner side of the glass curtain wall 11, it is possible to effectively block the sunlight penetrating the glass curtain wall 11 from entering the room, effectively reduce the heat gain through solar radiation in the room, and improve the thermal insulation performance of the renovated building. Therefore, it is possible to reduce the situation where the load of the air-conditioning equipment increases due to excessive heat gain through solar radiation in the room, and reduce the energy consumption of the renovated building.

[0043] This embodiment also effectively improves the thermal insulation performance of the second wall 20 by setting a first thermal insulation layer 22 on the inner side of the second wall 20, reduces the situation where heat flows through the second wall 20 and causes an increase in heating or air conditioning load, and effectively reduces the energy consumption of the renovated building. The first thermal insulation layer 22 can be a rock wool thermal insulation layer.

[0044] In addition, by setting at least one light-transmitting opening 21 on the second wall 20, a portion of the light penetrating the glass curtain wall 11 can enter the room through the light-transmitting opening 21, thereby ensuring the intensity of natural light in the room, reducing the impact of weakening natural light in the room due to the setting of the second wall 20, reducing the use of lighting equipment, and reducing the energy consumption of the renovated building.

[0045] Optionally, a closable daylighting window may be provided in the daylighting opening 21, and the daylighting window may be a high-performance daylighting window. Such a configuration can ensure the heat insulation performance and air tightness of the second wall 20.

[0046] In summary, the remodeled building provided in the embodiment of the present application, by setting a second wall 20 on the inner side of the glass curtain wall 11, the second wall 20 is used to effectively block the sunlight penetrating the glass curtain wall 11 from entering the room, thereby improving the heat insulation performance of the remodeled building; by setting a first thermal insulation layer 22 on the inner side of the second wall 20, the heat insulation performance of the second wall 20 is effectively improved, thereby ensuring and improving the heat insulation performance and thermal insulation performance of the remodeled building; by setting at least one daylighting opening 21 for light to penetrate in the second wall 20, a part of the light penetrating the glass curtain wall 11 is guided into the room, thereby ensuring the daylighting performance of the remodeled building. Therefore, the remodeled building provided in the embodiment of the present application can improve the daylighting performance, heat insulation performance and thermal insulation performance without destroying the existing structure of the glass curtain wall building.

[0047] See also Figure 3 , Figure 5 , Figure 6 In this embodiment, the renovated building further includes a floor slab 30 and a plurality of first beams 40 .

[0048] The floor 30 is covered on the top side of each first wall 10, and at least part of the edge of the floor 30 extends downward to form a main beam 31 connected to the first wall 10; a plurality of first beams 40 are formed by extending along the first direction a and arranged at intervals along the second direction b, the ends of the first beams 40 are connected to the main beams 31, and the tops of the first beams 40 are connected to the floor 30, wherein the second direction b is perpendicular to the first direction a, and the main beam 31 has a support section 311 located between two adjacent first beams 40, and a second thermal insulation layer 3111 is provided on the inner side of the support section 311. Optionally, the second thermal insulation layer 3111 may be a vacuum insulation board.

[0049] By adopting the above solution, the floor slab 30 can be supported by the main beam 31 and the plurality of first beams 40 , so as to ensure that the floor slab 30 is stably fixed to the top side of the first wall 10 .

[0050] The heat transfer between the transition support sections 311 can also be effectively alleviated by setting a second insulation layer 3111 on the inner side of the support section 311 , thereby effectively improving the insulation performance of the support section 311 and alleviating the thermal bridge effect on the main beam 31 .

[0051] See also Figure 3 , Figure 5 , Figure 6In this embodiment, the first beam 40 has a load-bearing section 41 disposed near the main beam 31 and having a preset length, the load-bearing section 41 has a load-bearing surface 411 facing the load-bearing section 41 of the adjacent first beam 40, the load-bearing surface 411 is provided with a first heat-insulating layer 4111, and the portion of the floor 30 located between two adjacent load-bearing sections 41 is provided with a second heat-insulating layer 32. The first heat-insulating layer 4111 may be an aerogel heat-insulating coating layer, and the second heat-insulating layer 32 may be an aerogel heat-insulating coating layer.

[0052] By adopting the above scheme, the first insulation layer 4111 can be set on the load-bearing surface 411 to effectively block the heat transfer between the load-bearing sections 41, effectively improve the thermal insulation performance of the load-bearing sections 41, and alleviate the thermal bridge effect on the first beam 40.

[0053] It is also possible to effectively block the heat transfer of the floor 30 portion between two adjacent load-bearing sections 41 by setting a second insulation layer 32 on the floor 30 portion corresponding to the portion between two adjacent load-bearing sections 41, thereby effectively improving the thermal insulation performance of the floor 30 portion between the two load-bearing sections 41 and alleviating the thermal bridge effect on the floor 30.

[0054] The length of the load-bearing section 41 can be set according to the actual scenario, and the first heat insulation layer 4111 set on the load-bearing section 41 can meet the requirement of blocking the heat transfer between the load-bearing sections 41. Compared with the implementation of setting the first heat insulation layer 4111 on the entire first beam 40, by setting the first heat insulation layer 4111 on the load-bearing section 41 of a preset length, the construction cost and construction difficulty can be greatly reduced, and the material consumption and renovation cost can be reduced.

[0055] See also Figure 3 In this embodiment, the renovated building also includes two secondary beams 50, which are extended along the first direction a and arranged at intervals along the second direction b. The top of the secondary beam 50 is connected to the floor 30, and each first beam 40 is arranged between the two second beams 50. The insulation material 110 is filled between adjacent second beams 50 and first beams 40.

[0056] By adopting the above solution, the two secondary beams 50 can cooperate with the first primary beams 40 to support the floor slab 30 , so as to ensure that the floor slab 30 is stably fixed to the top side of the first wall 10 .

[0057] It is also possible to effectively alleviate and transition the heat transfer between the adjacent second beams 50 and first beams 40 by filling the insulation material 110 between the adjacent second beams 50 and first beams 40, effectively improve the insulation performance between the second beams 50 and first beams 40, and alleviate the thermal bridge effect between the second beams 50 and first beams 40.

[0058] See also Figure 6 In this embodiment, a leveling layer 3112 is provided between the supporting section 311 and the second thermal insulation layer 3111 , and the side of the leveling layer 3112 facing the second thermal insulation layer 3111 is a plane.

[0059] By adopting the above solution, it can be ensured that the side of the leveling layer 3112 used to install the second insulation layer 3111 is a flat plane. Based on this, the second insulation layer 3111 can be stably installed on the supporting section 311, and the risk of the second insulation layer 3111 detaching from the supporting section 311 can be reduced.

[0060] See also Figure 3 , Figure 4 , Figure 5 In this embodiment, the glass curtain wall 11 includes a light-transmitting portion 111 opposite to the daylight opening 21, and a light-shielding portion 112 outside the light-transmitting portion 111. A light-transmitting and heat-insulating layer 1111 is arranged on the inner side of the light-transmitting portion 111, and a light-shielding and heat-insulating layer 1121 is arranged on the inner side of the light-shielding portion 112.

[0061] Among them, the light-transmitting heat-insulating layer 1111 can effectively block the infrared and ultraviolet bands in sunlight that are mainly responsible for heat generation, and allow some visible light to pass through, such as a transparent nano-thermal insulation coating layer or a thermal insulation film; the light-shielding heat-insulating layer 1121 can effectively block the infrared and ultraviolet bands in sunlight that are mainly responsible for heat generation, and can absorb most of the visible light, such as a dark-colored nano-thermal insulation coating layer or a thermal insulation film.

[0062] Therefore, by adopting the above-mentioned scheme, a light-transmitting heat-insulating layer 1111 can be provided on the inner side of the light-transmitting portion 111 opposite to the light-transmitting opening 21 to effectively block the infrared band in the sunlight that mainly causes heat, and allow part of the visible light to pass through the light-transmitting portion 111, the light-transmitting heat-insulating layer 1111 and the light-transmitting opening 21, thereby ensuring the indoor brightness, ensuring and improving the lighting performance of the renovated building, and correspondingly reducing the use of lighting equipment for adjusting the indoor brightness, which is beneficial to energy conservation and emission reduction.

[0063] A shading and heat-insulating layer 1121 can also be provided on the inner side of the shading portion 112 to more effectively block the infrared band in sunlight that mainly causes heat and block most of the visible light, thereby effectively reducing the solar heat gain coefficient of the glass curtain wall 11, improving the heat insulation performance of the glass curtain wall 11, and alleviating the indoor temperature in hot weather, thereby ensuring and improving the indoor temperature comfort of the renovated building, and correspondingly reducing the use of equipment such as air conditioners for adjusting the indoor temperature, which is beneficial to energy conservation and emission reduction.

[0064] See also Figure 3 , Figure 5 In this embodiment, the renovated building further includes a floor 60 sealed on the bottom side of each first wall 10 , and a third insulation layer 61 is provided on the floor 60 .

[0065] By adopting the above solution, the thermal insulation performance of the floor 60 can be effectively improved, and the risk of large-scale heat dissipation through the floor 60 can be reduced, thereby ensuring and improving the indoor temperature comfort of the renovated building, and correspondingly reducing the use of equipment such as air conditioners for adjusting the indoor temperature, which is beneficial to energy conservation and emission reduction.

Optionally, the fourth thermal insulation layer 121 may be a rock wool thermal insulation layer. In this way, the thermal insulation performance of the common wall 12 can be effectively improved, and the risk of heat being largely dissipated through the common wall 12 can be reduced, thereby ensuring and improving the indoor temperature comfort of the renovated building, and correspondingly reducing the use of equipment such as air conditioners for adjusting the indoor temperature, which is conducive to energy conservation and emission reduction.

In this way, when heating or cooling is required, the exchange of indoor air and outdoor air through the gaps and leaks of the ordinary wall 12 can be effectively reduced, thereby reducing the degree of heat loss, ensuring and improving the indoor temperature comfort of the renovated building, and correspondingly reducing the use of equipment such as air conditioners for adjusting the indoor temperature, which is conducive to energy conservation and emission reduction. In addition, the erosion effect of moisture intrusion on the structures of the renovated building can also be reduced.

[0078] By adopting the above solution, the air tightness of the second wall 20 can be improved.
