Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of building curtain wall, in particular to a curtain wall structure for energy-saving green building. BACKGROUND

[0002] In the energy-saving green building system, the curtain wall is not only the "clothing" of the building, but also the core component of realizing energy efficient utilization, improving the comfort of human settlement and environmental compatibility. It is not a wall that only plays a decorative and enclosing role in the traditional sense, but a composite building skin that integrates low-carbon materials, intelligent technology and ecological design, which can maximize energy consumption and reduce environmental impact while meeting the aesthetic needs of the building, and is a key link to the goal of green building.

[0003] In the current green building system, the energy-saving green curtain wall used is mostly made of high-transmittance glass combined with solar panels and thermal insulation materials. There are many types and different structural levels, but the basic principles are the same, that is, to realize green energy through solar panels and to achieve energy-saving through the layer structure design of thermal insulation materials. As a building curtain wall, considering the lightness of the structure, conventional solar panels are generally not used, and flexible solar cell films are increasingly used. The flexible solar cell film is pasted in the corresponding layer of the curtain wall structure to achieve the purpose of generating green energy. However, whether it is a conventional solar panel or a flexible solar cell film, there are problems in installation and construction when integrated into the curtain wall structure of modern buildings. Not only the sealing performance needs to be considered, but also the convenience of construction, especially the feasibility of subsequent maintenance. The existing flexible solar cell film is basically fixed in the corresponding structural layer of the curtain wall by adhesive, which is prone to local adhesion and wrinkling during installation, causing problems in the curtain wall structure layer. At the same time, the installation of flexible solar cell film is difficult to ensure reliability, especially when replacing it later, the entire curtain wall structure needs to be disassembled, layered, and the flexible solar cell film installation layer needs to be torn off, and then a new flexible solar cell film needs to be installed. This series of operations is very tedious and it is difficult to ensure that the flexible solar cell film can be accurately installed. SUMMARY

[0004] Therefore, the purpose of the present application is to provide a curtain wall structure for energy-saving green building to solve the problems in the background art and achieve the purposes of fast and accurate construction and convenient subsequent maintenance.

[0005] The present application is achieved by the following technical solutions: The utility model relates to a curtain wall structure for energy-saving green building, which comprises a frame, glass plates installed in the frame, and a flexible solar cell film covered by the glass plates, wherein the frame is open on one side and has an extension plate extending towards the plane of the frame on the other side, and the extension plate encloses an irradiation area for sunlight; the junction box of the flexible solar cell film is located on the back of one end thereof; further comprising an installation plate for flatly installing the flexible solar cell film, which is inserted into the frame along the thickness direction of the frame, and the upper and lower sides of the installation plate have a protruding part on the edge thereof, respectively, and each protruding part has an installation groove for plug-in connection with the junction box, so that the flexible solar cell film can be flatly laid on the central surface of the installation plate and fully cover the irradiation area after the junction box is installed in the installation groove; each of the two opposite sides of the frame has a strip-shaped insertion hole closed by a sealing plate, and the strip-shaped insertion hole is used for inserting the glass plate into the frame along the direction parallel to the installation plate; a regulating bolt is threadedly connected between the protruding part and the edge of the installation plate, and the regulating bolt is installed perpendicularly to the glass plate; the end of the regulating bolt is rotatably installed in a positioning strip plate, and the positioning strip plate is arranged opposite to the extension plate to form a positioning and installing channel for inserting the glass plate into the frame parallel to the installation plate, and the flexible solar cell film is gradually laid flat and closely attached to the surface of the installation plate during the inserting process.

[0006] Further, the strip-shaped insertion hole is rectangular, the frame is a rectangular frame, the width direction of the strip-shaped insertion hole is consistent with the frame, and the glass plate is inserted into the frame along the length direction of the frame; one of the two adjacent and parallel frames has a wire passing column on one side for the cable to pass through, and the corresponding side of the other frame is provided with an embedded hole for coaxial insertion of the wire passing column, and the embedded hole is communicated with the cable laying channel in the frame.

[0007] Further, a guide groove extending along the thickness direction of the frame is arranged on the inner side wall of the open end of the frame; each of the two opposite sides of the installation plate has a protruding lug, and the lug is slidably connected with the guide groove, and the installation plate is inserted into the frame along the extension direction of the guide groove by means of the lug.

[0008] Further, the junction box and the installation groove are both cuboid, and the junction box does not contact the groove bottom of the installation groove when it is inserted into place; a rain cover is arranged above the frame, and the rain cover is curled by 90 degrees downward on each side edge except the side connected with the wall, and the rain cover is hooked on the flange edge of the frame on one side and is fixedly installed close to the wall on the other side.

[0009] Further, one side of the edge of the installation plate is provided with a rectangular strip-shaped groove, the positioning strip plate is a rectangular plate, and the positioning strip plate is slidably installed in the strip-shaped groove, and the side of the positioning strip plate away from the regulating bolt is exposed from the groove opening of the strip-shaped groove.

[0010] Furthermore, a felt board is fixedly attached to the side of the positioning strip that exposes the groove, so as to clean the surface of the glass plate when the glass plate is inserted into the frame.

[0011] Furthermore, a disc spring is provided between the nut end of the adjusting bolt and the mounting plate, and the disc spring is sleeved on the adjusting bolt in a compressed state.

[0012] Furthermore, a heat insulation plate is detachably inserted into the side of the mounting plate opposite to the glass plate, which separates the mounting plate from the wall.

[0013] Furthermore, the junction box is connected to conductive pins, and an insulating sleeve is embedded and fixed in the bottom of the mounting groove. A conductive pin sleeve is coaxially fixed in the insulating sleeve, and the pin sleeve is connected to a cable embedded on the back of the mounting plate. When the junction box is installed in the mounting groove, the pins are inserted into the pin sleeves to transmit the electricity generated by the flexible solar cell film. The spacing between the extension plate and the mounting plate must allow the flexible solar cell film and its junction box to be directly pulled out of the mounting groove and moved out of the frame through the strip-shaped insertion hole.

[0014] Furthermore, the strip-shaped insertion hole is a stepped hole that is wider at the top and narrower at the bottom. A slot is perpendicular to it on the stepped surface near the outer side of the frame. A clamping bolt is elastically installed inside the side wall of the slot by a cylindrical spring. One end of the clamping bolt has a rectangular rubber block embedded in it, and the other end has a curved surface. When the insert plate is not inserted into the slot, the curved end of the clamping bolt is located inside the slot, and the entire clamping bolt is located inside the side wall of the slot. When the sealing plate is installed inside the frame, the insert plate is pressed into the installation position, and the insert plate pushes the clamping bolt to the position where the rubber block presses against the glass plate.

[0015] The beneficial effects of this invention are as follows: In short, the curtain wall structure used in this energy-saving and green building mainly utilizes a simple yet ingenious combination of positioning strips and frames to accurately insert glass panels, allowing the flexible solar cell film to be laid flat on the mounting plate and firmly pressed in place by clamping bolts. This ensures accurate and rapid installation of the flexible solar cell film without the need for conventional bonding methods, reducing the likelihood of localized wrinkles caused by bonding. At the same time, it fully guarantees sealing and waterproofing while facilitating quick disassembly and replacement in the future, making construction fast, accurate, and safe.

DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings herein can be arranged and designed in various different configurations.​​

[0020] Therefore, the following detailed description of the embodiments of the application provided in the drawings is not intended to limit the scope of the application claimed, but merely represents selected embodiments of the application. Based on the embodiments in the application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of the application.

[0021] It should be noted that similar signs and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0022] Referring to Figures 1-2 , the application provides a technical solution: a curtain wall structure for energy-saving green buildings, comprising a frame 1 and a glass plate 2 and a flexible solar cell film 4 installed in the frame 1, the flexible solar cell film 4 is covered by the glass plate 2, one side of the frame 1 is open to the wall 23, and the other side has an extension plate 101 extending towards the plane where the frame 1 is located. Specifically, the frame 1 can be composed of a frame body 102 and the above-mentioned extension plate 101, when the frame 1 is rectangular, the frame body 102 is a rectangular frame, and the extension plate 101 is also a rectangular frame plate structure extending towards one end of the rectangular frame, as shown in Figure 3 , which is the front of the frame 1, and the back, i.e. the side facing the wall 23, is roughly as shown in Figure 12 , the extension plate 101 forms a rectangular irradiation area where sunlight can enter. The junction box 6 of the flexible solar cell film 4 in this embodiment is located at the back of one end, for example, when the flexible solar cell film 4 is rectangular, the junction box 6 is fixed at the back of one end. At the same time, this embodiment also includes an installation plate 5 for flatly installing the flexible solar cell film 4, which is inserted into the frame 1 along the thickness direction of the frame 1, as shown in Figure 1 , the horizontal direction is the thickness direction of the frame 1. Each of the upper and lower sides of the installation plate 5 has a protruding part 501 near the edge, which protrudes towards the back, and each protruding part 501 has a mounting groove 50101 for plug-in cooperation with the junction box 6, so that after the junction box 6 is installed in the mounting groove 50101, the flexible solar cell film 4 can be flatly laid on the central surface of the installation plate 5 and fully cover the irradiation area, i.e. the junction box 6 also serves as a positioning element. In addition, each of the two opposite sides of the frame 1 has a strip-shaped insertion hole closed by a sealing plate 3. Specifically, the strip-shaped insertion hole is rectangular, the frame 1 is a rectangular frame, the strip-shaped insertion hole is consistent with the width direction of the frame 1, and the glass plate 2 is inserted into the frame 1 along the length direction of the frame 1. As shown in Figure 11In two adjacent side-by-side frame frames 1, i.e., when two adjacent curtain wall structures are installed, one frame frame 1 has a cable guide post 20 on one side for cables to pass through, and the corresponding side of the other frame frame 1 has an insertion hole 21 for the cable guide post 20 to be coaxially inserted. The insertion hole 21 is connected to the cable routing channel inside the frame 1. Specifically, as shown... Figure 1 In the middle, there is a sealing plate 3 at the top and bottom. The sealing plate 3 can be specifically as follows: Figure 11 The glass plate 2 is detachably embedded within the frame 1, as shown. This strip-shaped insertion hole allows the glass plate 2 to be inserted into the frame 1 in a direction parallel to the mounting plate 5; that is, when the frame 1 is vertically attached to the wall 23, the glass plate 2 is vertically inserted through the strip-shaped insertion hole. Furthermore, as... Figure 1 An adjusting bolt 7 is threadedly installed between the protrusion 501 and the edge of the mounting plate 5. The adjusting bolt 7 is installed perpendicular to the glass plate 2. To ensure that the adjusting bolt 7 is in a relatively stable position, a disc spring 13 is provided between the nut end of the adjusting bolt 7 and the mounting plate 5. The disc spring 13 is sleeved on the adjusting bolt 7 in a compressed state. The end of the adjusting bolt 7 is rotatably installed in a positioning strip plate 8. The positioning strip plate 8 is arranged opposite to the extension plate 101 to form a positioning and installation channel for inserting the glass plate 2 parallel to the mounting plate 5 into the frame 1. Moreover, the flexible solar cell film 4 can be laid flat during the insertion process. Specifically, due to the guiding effect between the positioning strip plate 8 and the extension plate 101, the glass plate 2 can be installed in a manner such as vertical insertion. During the installation process, after the flexible solar cell film 4 is positioned on the mounting plate 5 using the junction box 6, the flexible solar cell film 4 has a certain degree of flexibility, and its end away from the junction box 6 will usually curl to a certain extent. In this embodiment, the curled end can be located in the position of the flexible solar cell film 4. Figure 1 Between the lower extension plate 101 and the positioning strip plate 8, the flexible solar cell film 4 is first placed on the surface of the mounting plate 5. When the glass plate 2 is inserted into the frame 1 in the above-mentioned accurate posture, it can contact the flexible solar cell film 4 on the surface of the mounting plate 5, and then gradually flatten the flexible solar cell film 4, so that it is pressed tightly against the surface of the mounting plate 5 under the pressure of the glass plate 2.

[0023] In this embodiment, as Figure 1 A guide groove 10201 extending along the thickness direction of the frame 1 is provided on the inner wall of the open end of the frame 1. Each of the two opposite sides of the mounting plate 5 has a protruding lug 502, which is slidably connected to the guide groove 10201. The mounting plate 5 is inserted into the frame 1 along the extension direction of the guide groove 10201 by relying on the lug 502.

[0024] In this embodiment, the junction box 6 and the mounting groove 50101 are cuboid-shaped for positioning and mounting, and the junction box 6 does not contact the groove bottom of the mounting groove 50101 when inserted in place, avoiding the situation that the mounting groove 50101 is too shallow to allow the flexible solar cell film 4 to adhere to the surface of the mounting plate 5. In order to better prevent water and dust, such as Figure 9 A rain cover 22 can be provided above the frame 1, and the rain cover 22 is curled downward by 90 degrees on all sides except the side connected to the wall 23, so as to cover the upper part of the curtain wall structure. One side of the rain cover 22 hooks the flange edge (not shown in the figure) of the frame 1, and the other side is tightly fixed to the wall 23, so as to not only prevent rain and dust, but also avoid the danger of falling from a high altitude of the curtain wall structure. Figure 10

[0025] In this embodiment, as shown in Figures 1-2 One side of the mounting plate 5 near the edge is provided with a rectangular strip-shaped groove (not shown in the figure), and the positioning strip plate 8 is a rectangular plate, and reference is made to Figure 4 The positioning strip plate 8 is slidingly installed in the strip-shaped groove, and the side away from the adjusting bolt 7 is exposed from the slot of the strip-shaped groove to contact the glass plate 2. As a preferred design structure, in order to clean the glass plate 2 when installing the glass plate 2, and avoid scratching the flexible solar cell film 4, as shown in Figure 1 A felt plate 9 is fixedly attached to the side of the positioning strip plate 8 exposed from the strip-shaped groove, so as to clean the surface of the glass plate 2 when the glass plate 2 is inserted into the frame 1, and also avoid scratching the surface of the glass plate 2, so that the glass plate 2 can be more stably inserted.

[0026] In this embodiment, as shown in Figure 1 、 Figure 2 、 Figure 5 A heat insulation plate 11 is detachably inserted into the side of the mounting plate 5 away from the glass plate 2, and the heat insulation plate 11 separates the mounting plate 5 from the wall 23, so as to play a heat insulation role on the wall 23, avoiding waste of air conditioning power consumption in summer and winter. In order to facilitate the installation of the flexible solar cell film 4, as shown in Figure 2 and Figures 5-6 ​A conducting pin 14 is connected to the terminal box 6. An insulating sleeve 16 is fixed to the bottom of the installation groove 50101. A conducting pin sleeve 15 is coaxially fixed in the insulating sleeve 16. The pin sleeve 15 is connected to the cable embedded in the back of the installation plate 5. When the terminal box 6 is installed in the installation groove 50101, the pin 14 is inserted into the pin sleeve 15 to transmit the electricity generated by the flexible solar cell film 4. It should be noted that, in order to facilitate subsequent maintenance and replacement, the distance between the extension plate 101 and the installation plate 5 is preferably designed to allow the flexible solar cell film 4 and the terminal box 6 to be directly pulled out of the installation groove 50101 and moved out of the frame 1 through the strip-shaped insertion hole. Therefore, in practice, the terminal box 6 is preferably designed to be longer, so that the terminal box 6 can be thinner, thereby facilitating the removal from the above-mentioned space and moving out of the frame 1 through the strip-shaped insertion hole. Figure 5 The terminal box 6 is preferably designed to be longer, so that the terminal box 6 can be thinner, thereby facilitating the removal from the above-mentioned space and moving out of the frame 1 through the strip-shaped insertion hole.

[0027] Finally, as shown in Figures 1-2 , the strip-shaped insertion hole is a stepped hole with a wide upper part and a narrow lower part. The stepped hole has an insertion groove 10101 on the step surface outside the frame 1 and perpendicular to the frame 1. As shown in Figure 2 , Figure 7 , a compression bolt 17 is elastically installed in the side wall of the insertion groove 10101 through a cylindrical spring 18. One end of the compression bolt 17 is embedded with a rectangular rubber block 19. The other end of the compression bolt 17 has a curved surface. When the insertion plate 10 is not inserted into the insertion groove 10101, as shown in Figure 7 , the curved end 1701 of the compression bolt 17 is located in the insertion groove 10101, and the compression bolt 17 and the rubber block 19 are located in the side wall of the insertion groove 10101. As shown in Figure 1 , Figure 8 , when the corresponding sealing plate 3 is installed in the frame 1, the insertion plate 10 is pressed to the installation position, and the insertion plate 10 pushes the compression bolt 17 to the position where the rubber block 19 presses the glass plate 2.

[0028] The following are the construction points of the curtain wall structure for energy-saving green buildings in installation and maintenance: The curtain wall structure for energy-saving green buildings in the above embodiment is installed in the actual installation process, as shown in Figure 1The shown orientation is an example, first take off the upper side of the one sealing plate 3, expose the upper side of the one strip-shaped insertion hole, tighten the upper adjusting bolt 7 to the right place, and loosen the lower adjusting bolt 7 to retreat a distance, avoid the lower positioning strip plate 8 to contact with the glass plate 2 at the beginning, which may hinder the normal insertion; At the same time, ensure that the upper and lower two insertion plates 10 have been pulled out. In the above operation, for the position of the adjusting bolt 7 tightened, for example, a limiting cylinder (not shown in the figure) coaxial with the disc spring 13 is provided in the adjusting bolt 7, when the adjusting bolt 7 is tightened to the position that the nut contacts with the end of the limiting cylinder, that is, tightened to the right place, at this time, the positioning strip plate 8 and the extension plate 101 are within the set distance, for example, so that the positioning strip plate 8 can be in the same level with the flexible solar cell film 4, to guide the glass plate 2 to be inserted vertically, which can contact with the flexible solar cell film 4 to flatten the flexible solar cell film 4, and not to scratch the flexible solar cell film 4 by excessive extrusion. When the glass plate 2 is inserted into the right place, the upper adjusting bolt 7 can be slightly loosened, so that the positioning strip plate 8 (or the felt plate 9) does not extrude contact with the glass plate 2, that is, the adjusting bolt 7 removes the pressure on the glass plate 2, so that the subsequent insertion of the insertion plate 10 and the pushing of the pressing bolt 17 can not be extruded with the flexible solar cell film which has been flattened on the mounting plate 5 due to the contact of the positioning strip plate 8 or the felt plate 9. When the insertion plate 10 is inserted and the mounting plate 3 is closed, the insertion plate 10 extrudes the pressing bolt 17 to extrude the glass plate 2 towards the flexible solar cell film, so as to realize the accurate fixing and installation of the flexible solar cell film, and finally, the two adjusting bolts 7 are tightened again.

[0029] And in daily maintenance, only need to pull out the connecting bolt 12 for installing the curtain wall structure of the energy-saving green building to a certain distance, let the sealing plate 3 expose outside the surface of the curtain wall, in order to remove the sealing plate 3, then pull out the insertion plate 10, release the pressing bolt 17, that is, release the main pressing and fixing force on the glass plate 2, at this time, the glass plate 2 can be pulled out, or the glass plate 2 is vertically pushed out upwards from the frame 1, then the end of the flexible solar cell film which is close to the junction box 6 is pried out from the strip-shaped insertion hole, the junction box 6 is taken out, that is, the flexible solar cell film is taken out upwards, then the above-mentioned flexible solar cell film installation process is repeated to replace the new flexible solar cell film. Since the final installation position of the positioning strip plate 8 has been determined when the adjusting bolt 7 is finally tightened during the initial installation of the flexible solar cell film, the subsequent maintenance does not need to rotate the adjusting bolt 7 when the flexible solar cell film is reinstalled, so the curtain wall structure does not need to be completely removed from the wall 23. It can be seen that the curtain wall structure of the energy-saving green building has no curtain wall high-altitude falling risk during construction, whether it is initial installation or subsequent maintenance, it is fast, accurate and safe.
