DETAILED DESCRIPTION

[0039] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0040] The embodiments of the present application provide a photovoltaic thermal curtain wall assembly and a curtain wall system, which solves the problem that the curtain wall steel keel structure used for installing the photovoltaic thermal curtain wall serves as a potential heat loss channel, which will reduce the insulation effect and force the addition of additional insulation materials inside the building, resulting in thickening of the wall and occupation of internal space. When in use, the heat in the building is prevented from being absorbed and transferred and lost by the vertical keels of the curtain wall, thereby ensuring the normal operation of the curtain wall assembly without occupying too much available space inside the building.

[0041] The technical solution in the embodiment of the present application is to solve the above technical problems, and the overall idea is as follows:

[0042] Example 1

[0043] See also Figure 1-Figure 14 , a photovoltaic thermal curtain wall assembly, comprising:

[0044] The curtain wall vertical keels 2 are installed on the building structure beams 1 and are assembled in sections, with several curtain wall vertical keels 2 being distributed in parallel;

[0045] Curtain wall horizontal keels 3, a plurality of curtain wall horizontal keels 3 are installed equidistantly between two adjacent curtain wall vertical keels 2;

[0046] The heat preservation assembly 4 is arranged on the left and right sides of the rear part of the curtain wall vertical keel 2, and is also fixedly installed on the left and right sides of the building structure beam 1, and is used to isolate the heat transfer between the curtain wall vertical keel 2 and the heat in the building;

[0047] The thermal insulation component 5 is installed at the rear of the curtain wall horizontal keel 3 to isolate the heat transfer between the curtain wall horizontal keel 3 and the heat in the building;

[0048] The vertical plate partition 6 is installed on the left and right sides of the front part of the curtain wall vertical keel 2, and the top and bottom outer sides of the vertical plate partition 6 are both provided with inner concave slots 7;

[0049] The horizontal plate spacer 8 is installed at the top and bottom of the curtain wall horizontal keel 3, and the horizontal plate spacer 8 is clamped with the vertical plate spacer 6 through the concave clamping groove 7;

[0050] The curtain wall 11 is installed in front of the vertical partition 6 and the horizontal partition 8;

[0051] A caulking assembly 12 is also filled between the upper and lower curtain walls 11. Externally pressed aluminum strips 13 are provided on the left and right sides of the curtain wall 11, and the externally pressed aluminum strips 13 are installed in front of the curtain wall vertical keels 2. A moisture-proof sealing strip 14 is pasted on the rear wall of the externally pressed aluminum strips 13.

[0052] In this example, see Figure 1-Figure 14 As shown, the specific installation process of photovoltaic thermal curtain wall components is as follows:

[0053] The first step is to first determine the position of the exterior wall building structure beam 1, and then install the curtain wall vertical keels 2 in sections through metal connectors. After the installation is completed, the installation position of the curtain wall horizontal keels 3 is determined according to the width of the installed curtain wall 11, so that the left and right curtain wall vertical keels 2 and the upper and lower curtain wall horizontal keels 3 form a frame-shaped support structure for installing the curtain wall 11;

[0054] The second step is to install the insulation board 402 in the insulation assembly 4 on the left and right sides of the building structure beam 1 through the fitting 401, and then fill the insulation rock wool 15 between them, and then the upper and lower parts of the insulation board 402 are matched with the auxiliary workpiece 404 and the rock wool board 405 which are also installed on the building structure beam 1 to seal the top and bottom, so as to wrap the rear part of the curtain wall vertical keel 2 and the part of the connection between it and the building structure beam 1, so as to prevent the heat in the building from being absorbed and transferred by the curtain wall vertical keel 2;

[0055] Step 3: Continuing from Step 2, the back side (the side facing the building space) of the curtain wall horizontal keel 3 can be insulated and filled by the lightweight strip 501, the insulation inner strip 502, and the moisture-proof layer 503 in the insulation component 5 to prevent heat from being transferred and lost along the curtain wall horizontal keel 3;

[0056] Step 4: First, install the vertical plate partition 6 on the side of the vertical keel 2 of the curtain wall, and then insert and fix the horizontal plate partition 8 through the concave slot 7, and then the horizontal plate partition 8 half-wraps the horizontal keel 3 of the curtain wall, so that a heat insulation layer is formed between the vertical keel 2 of the curtain wall, the horizontal keel 3 of the curtain wall and the curtain wall 11, avoiding direct installation contact between the vertical keel 2 of the curtain wall and the horizontal keel 3 of the curtain wall and the curtain wall 11, avoiding heat transfer, and the front of the insulation board 402 in the insulation assembly 4 conflicts with the rear of the vertical plate partition 6 and the horizontal plate partition 8, further ensuring the insulation and wrapping effect of the vertical keel 2 of the curtain wall;

[0057] Step 5. After the curtain wall 11 is installed, the exterior of the curtain wall 11 can be pressed and fixed by installing an externally pressed aluminum strip 13 and a moisture-proof sealing strip 14 on the front of the curtain wall vertical keel 2. Finally, the caulking assembly 12 is directly installed on the upper and lower curtain walls 11, thereby completing the installation process of the entire curtain wall assembly.

[0058] In summary, the photovoltaic thermal curtain wall assembly isolates the heat transfer between the curtain wall vertical purlins 2, the curtain wall horizontal purlins 3 and the internal space of the building, ensuring that the temperature in the building does not dissipate, and also blocks the heat transfer of the connection installation between the curtain wall vertical purlins 2, the curtain wall horizontal purlins 3 and the curtain wall 11. The installation is simple and does not occupy too much building space. It has better insulation effect in buildings in cold areas, and will not affect the solar energy absorption of the photovoltaic thermal curtain wall assembly. Secondly, the above insulation structure between the curtain wall vertical purlins 2, the curtain wall horizontal purlins 3 and the curtain wall 11 can be disassembled and installed according to regional temperature changes, and is more flexible to use.

[0059] For further information, see Figure 3 , Figure 4 , Figure 5 , Fig.12 and Fig.13 The inner walls of the vertical plate partitions 6 and the horizontal plate partitions 8 are both installed with insulation pads 9, and the outer walls of the vertical plate partitions 6 and the horizontal plate partitions 8 are also installed with insulation sealing strips 10. By installing insulation pads 9 on the inner wall parts of the vertical plate partitions 6 and the horizontal plate partitions 8, the insulation pads 9 are made of insulation materials. As the position where the vertical plate partitions 6 and the horizontal plate partitions 8 contact the surfaces of the curtain wall vertical purlins 2 and the curtain wall horizontal purlins 3, possible tiny gaps can be filled and sealed to prevent external cold air or hot air from entering the interior of the building. By installing insulation sealing strips 10 on the outer wall parts of the vertical plate partitions 6 and the horizontal plate partitions 8, the curtain wall 11 can be sealed and installed on the vertical plate partitions 6 and the horizontal plate partitions 8 to ensure the sealing after mutual installation.

[0060] Example 2

[0061] See also Figure 6-Figure 9 , the thermal insulation component 4 comprises:

[0062] The fittings 401 are symmetrically arranged and installed on the left and right sides of the front part of the building structure beam 1;

[0063] The insulation board 402 is installed on the left and right sides of the building structure beam 1. The insulation board 402 is connected to the fitting 401 through a nut, and the cross section of the insulation board 402 is L-shaped;

[0064] The glass wool board 403 is bonded to the inner wall of the thermal insulation board 402 and is sealed to the wall of the building structure beam 1, and the cross section of the glass wool board 403 is also L-shaped.

[0065] In this example, see Figure 6-Figure 9 As shown, the fitting 401 serves as a connector between the insulation component 4 and the building structure beam 1, and plays a role in supporting and fixing the insulation board 402, and the insulation board 402 can form an insulation barrier between the building structure beam 1 and the indoor environment. Secondly, the cross-section of the insulation board 402 is L-shaped, which can be sealed with the subsequent vertical plate partition 6 and the horizontal plate partition 8 to better wrap the curtain wall vertical keel 2 and the sealing of the connector between the curtain wall vertical keel 2 and the building structure beam 1. Secondly, the inner wall of the insulation board 402 is also bonded with a glass wool board 403. On the one hand, it prevents the internal moisture of the building structure beam 1 from penetrating into the insulation board 402. On the other hand, it can better enable the insulation board 402 to be contacted and sealed with the building structure beam 1, further enhancing the insulation performance of the insulation component 4. At the same time, the glass wool board 403 has excellent insulation and fire resistance, and can effectively prevent the transfer of heat and the spread of fire.

[0066] For further information, see Figure 8 , the thermal insulation component 4 also includes:

[0067] Auxiliary workpiece 404 is sealed and arranged at the top and bottom of the insulation board 402, and installed at the front of the building structure beam 1;

[0068] The rock wool board 405 is installed in the middle of the auxiliary workpiece 404;

[0069] The drying layer 406 is disposed on the top of the rock wool board 405 .

[0070] In this example, see Figure 8As shown, the function of the auxiliary workpiece 404 is to cooperate with the fitting 401 and the insulation board 402, so that the insulation board 402 installed on the left and right sides of the building structure beam 1 cooperates with the auxiliary workpiece 404 and the rock wool board 405 installed on the upper and lower parts to form a sealed space, and the sealed space is filled with insulation rock wool 15. The rock wool board 405 is a high-performance thermal insulation material with excellent fireproof, sound insulation and thermal insulation properties. It wraps the curtain wall vertical keel 2 and its connecting parts, fills and insulates the curtain wall vertical keel 2, reduces the heat transfer in the building through the curtain wall vertical keel 2, and there is a drying layer 406 on the rock wool board 405, which is used to prevent moisture from penetrating into the insulation rock wool 15, keep the insulation rock wool 15 dry and stable, and protect the performance of the rock wool board 405 and the entire insulation assembly 4.

[0071] For further information, see Fig. 9 The left and right side fittings 401 are filled with thermal insulation rock wool 15, and the thermal insulation rock wool 15 wraps the connecting parts between the curtain wall vertical keel 2 and the building structure beam 1. The filled thermal insulation rock wool 15 can cut off the thermal bridge transfer of the curtain wall vertical keel 2, which not only insulates and preserves heat but also enhances structural stability, while improving the moisture and corrosion resistance of the building structure beam 1 and improving the building energy efficiency.

[0072] For further information, see Fig.10 A temperature detector 16 is installed on the side of the fitting 401, and a temperature measuring probe 17 is installed at the detection end of the temperature detector 16, and the temperature measuring probe 17 penetrates the outer wall of the fitting 401 and extends to the internal insulation rock wool 15.

[0073] By installing a temperature detector 16 on the side of the fitting 401 and extending it into the internal insulation rock wool 15 with a temperature measuring probe 17, a temperature monitoring function is achieved. The temperature detector 16, as an intelligent sensor, can monitor the temperature change of the internal insulation rock wool 15. When the temperature remains constant, it indicates that the internal insulation rock wool 15 is in a good insulation state. On the contrary, if the temperature of the internal insulation rock wool 15 decreases, it means that its insulation performance may be reduced. In addition, the temperature detector 16 also has the ability to detect external temperature differences. Two adjacent temperature detectors 16 can respectively measure and record the left and right temperature difference data of the curtain wall 11 between the two. The local temperature difference is helpful in capturing and monitoring the air leakage problem of the curtain wall 11.

[0074] Example 3

[0075] See also Figure 2 and Fig.14 , the thermal insulation component 5 comprises:

[0076] Lightweight strip board 501, installed at the rear of curtain wall horizontal keel 3;

[0077] The heat-insulating inner strip 502 is arranged in front of the light strip board 501 and fills the rear space of the curtain wall horizontal keel 3:

[0078] The moisture-proof layer 503 is arranged at the rear of the light-weight board 501 .

[0079] In this example, see Figure 2 and Fig.14 As shown, the thermal insulation component 5 composed of a lightweight strip 501, an insulating inner strip 502 and a moisture-proof layer 503 can be used to block heat transfer to the rear of the curtain wall cross keel 3, thereby improving the thermal insulation effect of the curtain wall cross keel 3. At the same time, the moisture-proof layer 503 can effectively prevent moisture from penetrating into the lightweight strip 501 and the insulating inner strip 502, thereby avoiding the loss of the thermal insulation effect.

[0080] For further information, see Figure 3 and Fig.11 , the caulking assembly 12 comprises:

[0081] The one-way air permeable plate 1201 is arranged in front of the curtain wall transverse keel 3 and is located between the upper and lower curtain walls 11;

[0082] A waterproof layer 1202, which is arranged at the rear of the one-way air permeable plate 1201;

[0083] The insulation layer 1203 is provided in front of the one-way air permeable plate 1201 .

[0084] The caulking assembly 12 is provided, on the one hand, when the insulation assembly 4, the vertical plate partitions 6 and the horizontal plate partitions 8 are all in the installation state, the main function of the caulking assembly 12 in this case is to ensure the sealing between the upper and lower curtain walls 11, strengthen the external sealing security at the curtain wall transverse keels 3 and the horizontal plate partitions 8, and prevent external cold air from entering the building through the gap and affecting the temperature inside the building; on the other hand, when the insulation assembly 4, the vertical plate partitions 6 and the horizontal plate partitions 8 are not in the installation state, the one-way air permeable plate 1201 in the caulking assembly 12 can be used to ensure that the air inside the building flows smoothly to the outside to prevent the interior from being stuffy. In addition, a waterproof layer 1202 is added to the rear of the one-way air permeable plate 1201 to prevent moisture inside the building from penetrating into the one-way air permeable plate 1201 and affecting its air permeability, thereby protecting the stability and durability of the curtain wall 11 structure.

[0085] For further information, see Fig.11As shown, the width of the partition insulation layer 1203 is greater than the width of the one-way breathable plate 1201, and when the one-way breathable plate 1201, the waterproof layer 1202 and the partition insulation layer 1203 are spliced, the outer sides of the front and back surfaces of the one-way breathable plate 1201 are used to cover the adhesive at the joints with the waterproof layer 1202 and the partition insulation layer 1203. The width of the partition insulation layer 1203 is designed to be greater than the width of the one-way breathable plate 1201, in order to effectively block the intrusion of external cold air, and the one-way breathable plate 1201, the waterproof layer 1202 and the partition insulation layer 1203 are spliced ​​at the joints and covered with the adhesive, thereby further reducing the risk of air and moisture penetrating through the joints, thereby improving the air tightness of the caulking assembly 12 and effectively reducing the entry of external air, moisture and impurities.

[0087] See also Fig.15 A curtain wall system includes the photovoltaic thermal curtain wall assembly and a temperature measurement module 18, wherein the temperature measurement module 18 includes a monitoring unit, an alarm unit and a recording unit; the monitoring unit is used to continuously receive and process temperature detection data from a temperature detector 16, and is used to monitor the temperature change of each section of thermal insulation rock wool 15 and the left and right temperature difference data of the curtain wall 11 between two adjacent temperature detectors 16; the alarm unit, the temperature detector 16 works in a series connection mode, and the unit can accurately identify and locate the area of ​​the curtain wall 11 where the temperature is abnormal, and alarm; the recording unit is used to record all information of the curtain wall 11 where temperature leakage occurs, so as to facilitate subsequent data analysis, troubleshooting or maintenance records.

[0088] In summary, through real-time monitoring and early warning, the system can promptly detect and deal with potential energy efficiency problems and safety hazards, thereby ensuring the overall energy efficiency and safety of curtain wall components, which helps to extend the service life of curtain wall components, reduce downtime and maintenance costs caused by failures, and improve the overall energy efficiency and environmental performance of the building.
