Description

Technical Field

[0001] This invention relates to the field of power-generating glass curtain wall technology, specifically to a BIM-based prefabricated power-generating glass curtain wall structure and its construction method. Background Technology

[0002] Power-generating glass is based on conventional glass and uses special materials / structural design to achieve the purpose of converting solar energy into electrical energy. It is not obviously different from conventional glass in appearance, but the following issues need special attention during the installation and construction of it as a curtain wall structure:

[0003] 1. Micron-level electrode grid lines exist at the edges of the power generation glass. During handling, edge bumps and damage must be avoided. Secondly, the gaps between each piece of power generation glass must be carefully considered. In addition to electrical isolation, attention must also be paid to the sealing and filling effect of the gaps and the range of expansion joints to avoid electrical risks caused by poor sealing and glass breakage due to thermal expansion.

[0004] 2. Due to the special structural design of the power generation glass, its own weight is relatively large, and wind load needs to be taken into account to avoid local microcracks in the battery cells caused by differences in the overall structure's load-bearing capacity. Therefore, its flatness needs to be ensured during construction.

[0005] To address this issue, the present invention proposes a solution. Summary of the Invention

[0006] The purpose of this invention is to provide a BIM-based prefabricated power-generating glass curtain wall structure and its construction method. Due to the special structural design of power-generating glass, attention needs to be paid to edge protection and gap filling during construction, and in particular, attention needs to be paid to the problem of local structural deformation caused by wind load.

[0007] The objective of this invention can be achieved through the following technical solution: a BIM-based prefabricated power-generating glass curtain wall structure, including a power-generating glass body, with oblique frames and corner seats respectively set at the four sides and corners of the power-generating glass body, and the power-generating glass body forming a wind cavity in the lower space of the four oblique frames.

[0008] The inclined frame is symmetrically arranged along the length or width of the power generation glass body, and the inclined frame is provided with a corresponding locking gap and adjustment gap for the power generation glass body. The inclined frame forms a slot along the center line area of ​​its length, and the outer wall position of the inclined frame corresponding to the slot is set as an inclined wedge. The corner seat and the inclined frame are fixed to the wall position by bolts.

[0009] The corner seat is further configured such that a pressure frame foot is installed at the bottom of the outer wall of the inclined frame. The upper surface of the pressure frame foot is inclined downward along the direction pointing to the inclined frame, and the pressure frame foot extends into the cavity to provide downward pressure on the inclined frame.

[0010] The configuration is further defined as follows: a fixed wedge is provided at the position of the slot corresponding to the inclined frame, the inclined surface of the fixed wedge is corresponding to the inclined wedge part, and a limiting plane is provided at the lower end of the fixed wedge and the bottom side of the inclined wedge part.

[0011] The configuration is further defined as follows: the inclined frame is provided with an inclined air duct at the position corresponding to the adjustment gap, the inclined air duct runs through the width direction of the inclined frame, and one end of the inclined air duct is connected to the inside of the air cavity.

[0012] The configuration is further defined as follows: a central base is provided in the central area inside the air cavity, and multiple blades arranged in a ring array are installed on the outer position of the central base, with multiple mounting sleeves installed on the blades along their linear direction.

[0013] The further configuration includes: a guide rod in the mounting sleeve corresponding to the blade tilt direction, the lower end of the guide rod being provided with a spring installed inside the mounting sleeve, and the top end of the guide rod having a ball head structure and being provided with a rubber support block corresponding to the lower side of the power generation glass body.

[0014] This invention also proposes a construction method for prefabricated power-generating glass curtain wall structures based on BIM. The method generates a layout diagram of the power-generating glass body using BIM, and then generates the following action process based on the layout diagram:

[0015] Action 1: First, fix the diagonal frame at three positions on the wall in the horizontal direction, namely left, right and bottom, with bolts. Then, assemble the central base on the wall. Finally, assemble the power generation glass body along the gap and fix the upper diagonal frame again.

[0016] Action 2: Assemble the inclined frame in the order from bottom to top, following the steps of Action 1. Fix the corner bracket at the corner of the inclined frame and ensure that the frame pressing foot extends into the slot of the inclined frame.

[0017] Action 3: Place a fixing wedge in the already fixed inclined frame and assemble it with the inclined frame using bolts. Use the inclined wedge to change the adjustment gap and limit the downward movement distance of the fixing wedge by the limiting plane, and complete the clamping process of each power generation glass body.

[0018] The present invention has the following beneficial effects:

[0019] 1. When using power-generating glass as a curtain wall structure, considering the special structural characteristics of power-generating glass, the overall installation frame structure is improved. The inclined frame is the main body, and the corner seat is the clamping structure. On the basis of fixing the power-generating glass, the inclined frame adds an inclined wedge inside, and adds a fixing wedge block. Specifically, the inclined surface design, combined with the adjustment gap, drives the inclined frame to spread along its width direction. The purpose is to change the installation gap of the power-generating glass in adjacent positions and further limit the downward movement distance of the fixing wedge block, thereby limiting the spread distance of the inclined frame, thus achieving the purpose of initially maintaining the installation position of the power-generating glass.

[0020] 2. Further improvements were made to the inclined frame. First, a central base was added to the wall at the lower side of the power generation glass, and blades were added to the outside of the central base. Rubber blocks on the mounting sleeve provided downward support to the lower side of the power generation glass. Second, an inclined air duct was added to the inclined frame structure. When the airflow enters the air cavity, it can drive the blades to rotate in a directional manner to maintain the level of the power generation glass in a way that simulates global support. The key purpose is to avoid small deformations in local areas of the power generation glass from affecting the overall effect and power generation quality. Attached Figure Description

[0030] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Example 1: Given the special structural design of power-generating glass, attention must be paid to edge protection and gap filling during construction, especially to the local structural deformation caused by wind loads. The following technical solution is proposed:

[0032] Reference Figures 1-7 The BIM-based prefabricated power-generating glass curtain wall structure in this embodiment includes a power-generating glass body 1, with inclined frames 4 and corner seats 2 respectively set at the four sides and corners of the power-generating glass body 1, and the power-generating glass body 1 forms a wind cavity in the lower space of the four inclined frames 4.

[0033] The inclined frame 4 is symmetrically arranged along the length or width of the power generation glass body 1, and the inclined frame 4 is provided with a corresponding locking gap 403 and adjustment gap 402 for the power generation glass body 1. The inclined frame 4 forms a slot along the center line area of ​​its length, and the outer wall position of the inclined frame 4 corresponding to the slot is set as an inclined wedge 401. The corner seat 2 and the inclined frame 4 are fixed to the wall position by bolts. The corner seat 2 is equipped with a frame foot 201 at the bottom position of the outer wall of the inclined frame 4. The upper surface of the frame foot 201 is inclined downward along the direction pointing to the inclined frame 4, and the frame foot 201 extends into the slot to provide downward pressure on the inclined frame 4.

[0034] A fixed wedge 3 is provided at the position of the slot corresponding to the inclined frame 4. The inclined surface of the fixed wedge 3 corresponds to the inclined wedge part 401. A limiting plane is provided at the lower end of the fixed wedge 3 and the bottom side of the inclined wedge part 401. An inclined air duct 404 is opened at the position of the adjustment gap 402 corresponding to the inclined frame 4. The inclined air duct 404 runs through the width direction of the inclined frame 4, and one end of the inclined air duct 404 is connected to the inside of the air cavity. A central base 5 is provided in the center point area inside the air cavity.

[0035] Multiple blades 7 arranged in a ring array are installed on the outer side of the central base 5. Multiple mounting sleeves 6 are installed on the blades 7 along their linear direction. A guide rod 601 corresponding to the tilt direction of the blade 7 is installed in the mounting sleeve 6. A spring 602 is installed inside the mounting sleeve 6 at the lower end of the guide rod 601. The top of the guide rod 601 has a ball head structure and is equipped with a rubber support block 8 corresponding to the lower side of the power generation glass body 1.

[0036] Structural Principle: The traditional glass curtain wall structure essentially involves installing frames along the four sides of the glass, with the frames fixed within the wall. However, the structure of power-generating glass differs significantly from conventional glass in that it incorporates special materials in its interlayer to achieve power generation. Figure 1 For example, the inclined frame 4 is the main structure. The length of the inclined frame 4 is limited according to the length of the power generation glass. In addition, corner seats are added at the corner positions of each inclined frame 4. Both the inclined frame 4 and the corner seats 2 are fixed to the wall with bolts. The two structures have the following characteristics:

[0037] S1: Reference Figure 3 and Figure 4 The inclined frame 4 is a completely symmetrical structure, and its central area forms a completely through slot. Taking one side of the structure as an example: First, the locking gap 403 is mainly used to lock the power generation glass body 1, but there is also an adjustment gap 402. The adjustment gap 402 can serve as the installation space for the battery cell components on the power generation glass body 1, and also as the space for adjusting the gap between two adjacent positions of the power generation glass body 1.

[0038] S2: Taking S1 as an example, a wedge 401 is added to the inner side of the inclined frame 4 relative to the upper side of the slot. In the normal state, after the inclined frame 4 is fixed to the wall, a fixing wedge 3 can be further added to the upper side of the slot, as shown in the figure. Figure 3 Explanation: The inclined design of the fixed wedge 3 and the inclined wedge 401 causes the local position of the corresponding inclined wedge 401 in the inclined frame 4 to be squeezed and spread towards the power generation glass body 1 when the fixed wedge 3 moves down. The purpose is to further limit the gap between each power generation glass body 1, and to reinforce and stabilize the installation position of the power generation glass body 1. The key role is to initially maintain the levelness of the power generation glass body 1.

[0039] S3: Again Figure 2For example, the corner seat 2 mainly reinforces the inclined frame 4 by pressing the frame foot 201. After the inclined frame 4 is fixed, the frame foot 201 is located at both ends of the slot. The fixed corner seat 2 further restricts the installation position and fixing force of the inclined frame 4. However, it should be noted that since the slot is completely open, there may be water accumulation in rainy weather. Therefore, it is necessary to limit the upper surface of the frame foot 201 to be a sloped design to avoid water accumulation between the corner seat 2 and the inclined frame 4.

[0040] S4: Further reference Figure 3 , Figure 6 and Figure 7 When installing the power generation glass body 1, it is also necessary to further install the central base 5 on the wall first. Specifically, it is also installed by bolt structure, but the actual installation process is different: first, install the rotating sleeve at the designated position on the wall, and then insert the central base 5 into the rotating sleeve to ensure that the central base 5 and the rotating sleeve maintain rotation.

[0041] The key point is: the blades 7 installed on the outside of the central base 5, so as to... Figure 7 For example, several mounting sleeves 6 are installed according to the tilt angle of the blade 7, and a guide rod 601 corresponding to the tilt direction is set inside the mounting sleeve 6. A rubber support block 8 is set at the top of the guide rod 601. The upper surface of the rubber support block 8 is designed with an arc surface. After the power generation glass body 1 is assembled, each rubber support block 8 is pressed to provide an upward reaction force to the power generation glass body 1, which corresponds to a downward force. Each spring 602 may be in a compressed state.

[0042] S5: Combining S4 and S2 and referring to Figure 5 To explain, an inclined air duct 404 is added at the adjustment gap 402. Because the curtain wall structure is a high-rise structure, its airflow intensity is relatively large. Therefore, after the overall assembly is completed, the strong airflow at high altitude can enter the air cavity through the inclined air duct 404. The purpose is to drive the overall central base 5 to rotate in a directional manner, while ensuring that each rubber support block 8 provides non-directional support. If the power generation glass body 1 deforms in a local position, the degree of contraction of the spring 602 in the corresponding position can be used to change the magnitude of the support force of the rubber support block 8 on the lower side of the power generation glass body 1. In essence, the rotation area of ​​the overall blade 7 is a perfect circle, and the deformation position is uncertain. Therefore, when the blade 7 rotates in a perfect circle, the levelness of the power generation glass body 1 can be maintained in a global support manner.

[0043] Example 2: Based on Example 1, supplementary explanation of the overall installation process is provided:

[0044] A layout diagram of the power-generating glass body 1 is generated using BIM, and the following action process is generated based on the layout diagram:

[0045] Action 1: First, fix the diagonal frame 4 at three positions on the wall in the horizontal direction with bolts, and then assemble the central base 5 on the wall. Finally, assemble the power generation glass body 1 along the locking gap 403 and fix the upward diagonal frame 4 again.

[0046] Action 2: Assemble the inclined frame 4 in the order from bottom to top according to the steps of Action 1, and fix the corner seat 2 at the corner position of the inclined frame 4, and ensure that the frame pressing foot 201 extends into the empty groove of the inclined frame 4.

[0047] Action 3: Place the fixing wedge 3 in the fixed inclined frame 4 and assemble it with the inclined frame 4 using bolts. Use the inclined wedge 401 to change the adjustment gap 402 and limit the downward movement distance of the fixing wedge 3 by the limiting plane, and complete the clamping process of each power generation glass body 1.

[0048] Solution Description: The construction process of the power-generating glass curtain wall is basically similar to that of conventional curtain wall structures. However, based on its power generation characteristics, the power-generating glass curtain wall first requires BIM software to plan the construction drawings. This process involves setting the placement of the power-generating glass body 1 based on factors such as color and power generation efficiency. This part will not be elaborated on in detail. The key point to explain is the following construction details based on the technical content in Example 1:

[0049] Detail 1: First, it is important to pay attention to the construction sequence. The installation must proceed from bottom to top. First, the diagonal frame 4 is erected in the horizontal direction. It is also important to note that one power generation glass body 1 requires four diagonal frames 4. The installation process of the four diagonal frames 4 involves installing three diagonal frames 4 at three locations: bottom, left, and right. Then, the central base is installed at the center point of the three diagonal frames 4. Finally, the power generation glass body 1 is secured in the locking gap 403.

[0050] Detail 2: Based on the above, another inclined frame 4 is added to form a closed frame by combining four inclined frames 4. Then, corner seats 2 are installed at the corners of the four inclined frames 4 to fix the inclined frames 4 with the frame feet 201. The key point is that the fixing wedges 3 are fastened to the upper part of the inclined frame 4. The purpose is to reinforce the power generation glass body 1 in the length and width directions. It should be noted that a limiting plane is set on the lower side of each inclined wedge 401. The purpose is to limit the downward movement distance of the fixing wedges 3 and thus limit the diffusion distance of the power generation glass body 1.

[0051] The sealing process for the power generation glass body 1 at the gap 403 is not specified in this invention.

[0052] In summary, when constructing a curtain wall structure using power-generating glass, considering its unique structural characteristics, an adjustment gap and fixing wedges are added to the bolted, inclined frame as a base. Specifically, the glass contracts along its four sides, limiting the placement of the fixing wedges and the inclined wedges. The key objective is to ensure the contraction distance of each power-generating glass panel to maintain the horizontality of adjacent panels. Furthermore, a central base and blades are added to the wall structure. These directional, rotatable blades provide downward support to the lower surface of the power-generating glass, further maintaining its installation position and preventing minor deformations in certain areas from affecting the overall effect and power generation quality.

[0053] The preferred embodiments of the present invention disclosed above are merely illustrative of the invention. These preferred embodiments do not exhaustively describe all details, nor do they limit the invention to specific implementations. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of the invention, thereby enabling those skilled in the art to better understand and utilize the invention. The invention is limited only by the claims and their full scope and equivalents.
