AI Technical Summary
In existing technologies, the lack of effective control over the compressive force on glass panels during installation of glass curtain walls makes the glass prone to breakage due to excessive compressive force.
By installing a pressure regulating device on the horizontal keel, the compressive pressure of the glass plate is adjusted. Initial stress spot images are obtained using a polarized light source and a camera. The height of the pressure regulating device is adjusted by calculating the similarity of the stress spots to ensure that the glass plate is subjected to balanced force during installation.
This effectively prevents the glass panels from shattering due to excessive pressure during installation, thus improving the safety and stability of the glass curtain wall.

Description
Technical Field
[0001] This invention belongs to the field of glass curtain wall technology, and more specifically, relates to a complete construction method for glass curtain walls. Background Technology
[0002] With the construction of large-scale buildings such as commercial and office buildings in various places, glass curtain walls have become an important part of the overall building system. Glass curtain walls generally include horizontal keels, vertical keels and glass panels, among which tempered glass or semi-tempered glass is generally used.
[0003] Chinese invention patent (patent number CN202010489634.3) with publication number CN111576691B discloses a frame-type glass curtain wall installation method and glass curtain wall system, including: processing horizontal and vertical keels for installing glass into shape; transporting the horizontal keels, the vertical keels, and connecting components for connecting the horizontal and vertical keels to the target floor, and installing the horizontal keels, vertical keels, and connecting components to form multiple target keel modules; installing each of the multiple target keel modules onto the curtain wall in a set installation sequence using a crane, and spot welding each installed target keel module to form a target keel frame.
[0004] The invention lacks a detailed process for fixing the glass plate and does not consider the compressive force received after the glass plate is installed and fixed. If the compressive force received by the glass plate is too large, it will cause the glass to easily break over time. Summary of the Invention
[0005] In view of this, the present invention provides a complete construction method for glass curtain walls, which takes into account the compressive force on the glass during the installation process, thus avoiding the technical problem that if the compressive force on the glass panel is too large, the glass will easily break over time.
[0006] This invention is implemented as follows:
[0007] This invention provides a complete construction method for glass curtain walls, comprising the following steps:
[0008] Determine the initial stress pattern: Obtain the initial image set for each glass plate when it is placed vertically;
[0009] Install pressure regulating devices: Install pressure regulating devices on multiple horizontal keels;
[0010] Keel splicing: Multiple horizontal and vertical keels that have been equipped with pressure regulating devices are spliced and assembled in sequence to form an extended grid-shaped keel frame;
[0011] Glass plate installation: The glass plate is installed on the keel frame, with the lower end of the glass plate abutting against the pressure regulating device, and the glass plate is fixed by the fixing structure;
[0012] Pressure adjustment: Adjust the height of the pressure regulating device to a suitable level, and further adjust the pressure device based on the similarity of stress spots on the initial image set;
[0013] Sealing treatment: Use rubber strips and sealant to fill the gaps between the glass plate and the adjusting horizontal and vertical keels;
[0014] Surface cleaning: Clean the dust and debris from the horizontal and vertical keels and the glass panel surfaces.
[0015] The technical advantages of the glass curtain wall construction method provided by this invention are as follows: When each glass panel is placed vertically, since it is not subjected to downward compressive force from above, the initial image shows a stress spot with the minimum stress. When the glass panel is installed on the frame, the pressure regulating device needs to be adjusted upwards, causing the glass panel to be subjected to compressive force from the upper and lower horizontal keels. At this time, the stress spot will change. Therefore, the change in stress spot can be used as a reference for the magnitude of stress formed by the glass panel under compression. The entire installation process, by taking into account the compressive force on the glass panel, can effectively avoid excessive compressive force on the glass panel during installation, thus preventing unsafe situations.
[0016] The glass plate is made of tempered glass or semi-tempered glass.
[0017] Based on the above technical solution, the glass curtain wall construction method of the present invention can be further improved as follows:
[0018] The transverse keel has a mounting groove in its transverse middle section, and a transverse fixing groove is provided on the back of the transverse keel at a position corresponding to the mounting groove. The width of the fixing groove matches the width of the glass plate, and the width of the mounting groove matches the width of the glass plate. A retaining groove with a width of 3cm to 6cm is provided on one side of the mounting groove. The mounting groove and the retaining groove are separated by a flip-up partition plate, which is hinged to the bottom wall of the mounting groove. The transverse keel also includes a retaining block, the size of which matches the retaining groove, and the retaining block is movably embedded in the retaining groove. The pressure regulating device includes a support block, a support bolt, and an adjusting nut. The length of the support block matches the length of the mounting groove, and the width of the support block matches the width of the mounting groove. The support block has a height greater than 1 cm. Multiple first bolt holes are provided on the bottom wall of the mounting groove. Multiple second bolt holes are provided at corresponding positions on the support block and the second bolt holes. The inner diameters and threads of the first and second bolt holes are the same. The first and second bolt holes are connected by support bolts. An adjusting nut is fitted on the outside of the support bolt. The height difference between the upper surface of the support block and the upper surface of the horizontal keel is greater than 1 cm, and the height of the upper surface of the support block is lower than the height of the upper surface of the horizontal keel. Vertical fixing grooves are provided on both sides of the vertical keel, and the width of the vertical fixing grooves matches the glass plate. Within the square structure formed by two adjacent horizontal keels and two adjacent vertical keels, the mounting groove, the vertical fixing groove, and the two vertical fixing grooves form a square through-slot for installing and fixing the glass.
[0019] The distance between the bottom walls of the vertical fixing grooves of two adjacent vertical keels is matched with the width of the glass plate. Preferably, the distance is 1mm to 5mm larger than the width of the glass plate. In addition, when the support block is at its lowest point, the distance between the top of the support block and the bottom of the horizontal fixing groove of the adjacent top horizontal keel is greater than the height of the glass plate. When the support block is at its highest point, the distance is less than the height of the glass plate.
[0020] In addition, the distance between the opposite surfaces of two adjacent horizontal keels on the keel frame is less than the height of the glass plate; the distance between the opposite surfaces of two adjacent vertical keels on the keel frame is less than the width of the glass plate.
[0021] Furthermore, the specific steps for determining the initial stress spot are as follows:
[0022] Stand the glass plate vertically on a horizontal surface;
[0023] Manually adjust the glass plate to ensure it is vertical;
[0024] A polarizing light source is set on one side of a glass plate, and a camera is set on the other side of the glass plate. The distance between the polarizing light source and the glass plate is 0.5m to 10m. The central axis of the light emitted by the polarizing light source is perpendicular to the glass plate. The polarizing light source is projected onto the center point of the glass plate. The camera is used to capture images of the glass plate.
[0025] Record the camera position relative to the glass plate, record the position of the polarized light source relative to the glass plate, and capture the first initial image of the glass plate;
[0026] Adjust the position of the polarized light source, record the position of the polarized light source relative to the second light source on the glass plate, and take a second initial image of the glass plate;
[0027] The initial image set includes a first initial image, a first light source position, a second initial image, and a second light source position.
[0028] Furthermore, the lower end of the glass plate abuts against the pressure regulating device, specifically:
[0029] Simultaneously rotate all the adjusting nuts on the support block to adjust the support block to its lowest position using the adjusting nuts;
[0030] The lower end of the glass plate abuts against the upper surface of the support block.
[0031] Furthermore, the specific steps for adjusting the height of the voltage regulating device to a suitable level are as follows:
[0032] Simultaneously rotate all the adjusting nuts on the support block to adjust the support block upwards. When the upper side of the glass plate abuts against the bottom wall of the horizontal fixing groove of the adjacent top horizontal keel, stop rotating all the adjusting nuts on the support block.
[0033] Furthermore, the specific steps for further adjusting the pressure device based on the similarity of stress spots on the initial image set include:
[0034] Step 1: Obtain the current image set;
[0035] Step 2: Calculate the mounting similarity of the current image set and the initial image set;
[0036] Step 3: If the installation similarity is greater than 0.97, rotate all the adjusting nuts on the support block simultaneously and use the adjusting nuts to adjust the support block upward. During the adjustment process, repeat steps 1 and 2 continuously until the installation similarity is between 0.9 and 0.97, then stop adjusting the support block upward.
[0037] Furthermore, the step of obtaining the current image set specifically includes:
[0038] A polarized light source is fixed according to the position of the first light source in the initial image set, and a camera is fixed according to the position of the camera to capture the first current image;
[0039] Based on the position of the second light source in the initial image set, a polarized light source is fixed, and a second current image is captured.
[0040] The current image set includes a first current image and a second current image.
[0041] Furthermore, the specific steps for calculating the installation similarity between the current image set and the initial image set include:
[0042] Calculate the first similarity between the first current image in the current image set and the first initial image in the initial image set;
[0043] Calculate the second similarity between the second current image in the current image set and the second initial image in the initial image set;
[0044] The average of the first similarity and the second similarity is used as the installation similarity between the current image set and the initial image set.
[0045] Furthermore, the step of calculating the first similarity between the first current image in the current image set and the first initial image in the initial image set specifically includes:
[0046] Image preprocessing: Preprocess the first current image to obtain image A, and preprocess the first initial image to obtain image B;
[0047] All stress spot contours in image A are denoted as the first stress spot contour set, and all stress spot contours in image B are denoted as the second stress spot contour set.
[0048] Calculate the first normalized central moments of all stress spot contours in the first stress spot contour set and the second normalized central moments of all stress spot contours in the second stress spot contour set, respectively.
[0049] The first stress spot contour feature is calculated based on the first normalized central moment, and the second stress spot contour feature is calculated based on the second normalized central moment; wherein, both the first stress spot contour feature and the second stress spot contour feature include a center and an area.
[0050] Calculate the similarity between the contour features of the first stress spot and the contour features of the second stress spot, and use it as the first similarity between the first current image in the current image set and the first initial image in the initial image set;
[0051] The step of calculating the second similarity between the second current image in the current image set and the second initial image in the initial image set specifically includes:
[0052] Image preprocessing: Preprocess the second current image to obtain an image, and preprocess the second initial image to obtain a D image;
[0053] All stress spot contours in image C are denoted as the third stress spot contour set, and all stress spot contours in image D are denoted as the fourth stress spot contour set.
[0054] Calculate the third normalized central moments of all stress spot contours in the third stress spot contour set and the fourth normalized central moments of all stress spot contours in the fourth stress spot contour set, respectively.
[0055] The third stress spot contour feature is calculated based on the third normalized central moment, and the fourth stress spot contour feature is calculated based on the fourth normalized central moment; wherein, both the third stress spot contour feature and the fourth stress spot contour feature include a center and an area;
[0056] Calculate the similarity between the contour features of the third stress spot and the contour features of the fourth stress spot, and use it as the second similarity between the second current image in the current image set and the second initial image in the initial image set.
[0057] Furthermore, the similarity between the first contour feature and the second contour feature, as well as the similarity between the third contour feature and the fourth contour feature, are all calculated using the cosine similarity calculation method.
[0058] Compared with existing technologies, the beneficial effects of the glass curtain wall construction method provided by this invention are as follows: When each glass panel is placed vertically, since it is not subjected to downward compressive force from above, the initial image shows a stress spot with the minimum stress. When the glass panel is installed on the frame, the pressure regulating device needs to be adjusted upwards, causing the glass panel to be subjected to compressive force from the upper and lower horizontal keels. At this time, the stress spot will change. Therefore, the change in stress spot can be used as a reference for the magnitude of stress formed by the glass panel under compression. The entire installation process, by taking into account the compressive force on the glass panel, can effectively avoid excessive compressive force on the glass panel during installation, thus preventing unsafe situations.

[0070] like Figure 1-3 The diagram shown is a schematic representation of relevant structures in one embodiment of a glass curtain wall construction method provided by the present invention. This method includes the following steps:
[0071] Determine the initial stress pattern: Obtain the initial image set for each glass plate when it is placed vertically;
[0072] Install pressure regulating devices: Install pressure regulating devices on multiple horizontal keels;
[0073] Keel splicing: Multiple horizontal and vertical keels that have been equipped with pressure regulating devices are spliced and assembled in sequence to form an extended grid-shaped keel frame;
[0074] Glass panel installation: Install the glass panel on the keel frame, with the lower end of the glass panel abutting against the pressure regulating device, and fix the glass panel using the fixing structure;
[0075] Pressure adjustment: Adjust the height of the pressure regulating device to a suitable level, and further adjust the pressure device based on the similarity of stress spots on the initial image set;
[0076] Sealing treatment: Use rubber strips and sealant to fill the gaps between the glass plate and the adjusting horizontal and vertical keels;
[0077] Surface cleaning: Clean the dust and debris from the horizontal and vertical keels and the glass panel surfaces.
[0078] The glass panels used in glass curtain walls are physically tempered or semi-tempered glass, and their anisotropy is unavoidable. This anisotropy is mainly due to uneven heating and cooling, resulting in different stress distributions on the glass surface. According to photoelastic theory, the presence of stress in the glass causes birefringence of light. This birefringence can be observed using polarized light. By placing tempered or semi-tempered glass under polarized light, changes in color and brightness in different areas of the glass surface can be observed; these are commonly referred to as stress spots. When the compressive force on the tempered or semi-tempered glass increases, the corresponding stress spots will shift or change in area, differing from the initial stress spots. The similarity between the two can be used to evaluate the magnitude of the compressive force.
[0079] In the above technical solution, a mounting groove 11 is provided in the middle of the horizontal keel, and a horizontal fixing groove 15 is provided on the back of the horizontal keel at a position corresponding to the mounting groove 11. The width of the horizontal fixing groove 15 matches the width of the glass plate, and the width of the mounting groove 11 matches the width of the glass plate. A retaining groove 12 is provided on one side of the mounting groove 11. The width of the retaining groove 12 is 3cm to 6cm. The mounting groove 11 and the retaining groove 12 are separated by a flip-up partition plate 13. The partition plate 13 is installed on the bottom wall of the mounting groove 11 by hinges. The horizontal keel also includes a retaining block 121. The size of the retaining block 121 matches the retaining groove 12, and the retaining block 121 is movably embedded in the retaining groove 12. The pressure regulating device includes a support block 14, a support bolt 141, and an adjusting nut 142. The length of the support block 14 matches the length of the mounting groove 11, and the width of the support block 14 matches the width of the mounting groove 11. The width of the support block 14 is matched with the width of the support block 14. The height of the support block 14 is greater than 1cm. Multiple first bolt holes are provided on the bottom wall of the mounting groove 11. Multiple second bolt holes are provided at the corresponding positions of the support block 14 and the second bolt holes. The inner diameter and threads of the first bolt holes and the second bolt holes are the same. The first bolt holes and the second bolt holes are connected by support bolts 141. Adjusting nuts 142 are sleeved on the outside of the support bolts 141. The height difference between the upper surface of the support block 14 and the upper surface of the horizontal keel 10 is greater than 1cm, and the height of the upper surface of the support block 14 is lower than the height of the upper surface of the horizontal keel 10. Vertical fixing grooves 21 are provided on both sides of the vertical keel 20. The width of the vertical fixing grooves 21 matches the glass plate. Within the square structure formed by two adjacent horizontal keels and two adjacent vertical keels 20, the mounting groove 11, the vertical fixing grooves 21 and the two vertical fixing grooves 21 form a square through groove for installing and fixing the glass.
[0080] During production, the length of the retaining block 121 is 1mm shorter than the length of the retaining groove 12, and the width of the retaining block 121 is equal to or slightly smaller than the width of the retaining groove 12, so that the retaining block 121 can be movably embedded in the retaining groove 12. The length of the support block 14 is 1mm shorter than the length of the mounting groove 11, and the width of the support block 14 is 1mm smaller than the width of the mounting groove 11, so that the support block 14 is placed in the retaining groove 12. When the keel splicing is completed, the lower end of the glass plate is installed in the mounting groove 11, and the left and right sides of the glass plate are just embedded in the vertical fixing grooves 21 of the two vertical keels 20. The upper side of the glass plate is embedded in the horizontal fixing groove 15 of the adjacent top horizontal keel 10, and the upper side of the glass plate does not abut against the bottom wall of the horizontal fixing groove 15 of the adjacent top horizontal keel 10.
[0081] Furthermore, in the above technical solution, the specific steps for determining the initial stress spot are as follows:
[0082] Stand the glass plate vertically on a horizontal surface;
[0083] Manually adjust the glass plate to ensure it is vertical;
[0084] A polarized light source is placed on one side of a glass plate, and a camera is placed on the other side of the glass plate. The distance between the polarized light source and the glass plate is 0.5m to 10m. The central axis of the light emitted by the polarized light source is perpendicular to the glass plate. The polarized light source is projected onto the center point of the glass plate. The camera is used to capture images of the glass plate.
[0085] Record the camera position relative to the glass plate, record the position of the polarized light source relative to the glass plate, and capture the first initial image of the glass plate;
[0086] Adjust the position of the polarized light source, record the position of the polarized light source relative to the second light source on the glass plate, and take a second initial image of the glass plate;
[0087] The initial image set includes a first initial image, a first light source position, a second initial image, and a second light source position.
[0088] Furthermore, the polarization light source can be adjusted to multiple positions, and the corresponding initial images can be recorded. The resulting multiple initial images and their corresponding light source positions are all used as elements of the initial image set.
[0089] Furthermore, in the above technical solution, the lower end of the glass plate abuts against the pressure regulating device, specifically as follows:
[0090] Simultaneously rotate all the adjusting nuts 142 on the support block 14, and use the adjusting nuts 142 to adjust the support block 14 to its lowest position;
[0091] The lower end of the glass plate abuts against the upper surface of the support block 14.
[0092] Furthermore, in the above technical solution, the specific steps for adjusting the height of the pressure regulating device to a suitable level are as follows:
[0093] All adjusting nuts 142 on the support block 14 are rotated synchronously to adjust the support block 14 upwards. When the upper side of the glass plate abuts against the bottom wall of the horizontal fixing groove 15 of the adjacent top horizontal keel 10, all adjusting nuts 142 on the support block 14 are stopped from rotating.
[0094] Furthermore, in the above technical solution, the specific steps for further adjusting the pressure device based on the similarity of stress spots on the initial image set include:
[0095] Step 1: Obtain the current image set;
[0096] Step 2: Calculate the mounting similarity of the current image set and the initial image set;
[0097] Step 3: If the installation similarity is greater than 0.97, rotate all the adjusting nuts 142 on the support block 14 simultaneously and use the adjusting nuts 142 to adjust the support block 14 upward. During the adjustment process, repeat steps 1 and 2 continuously until the installation similarity is between 0.9 and 0.97, then stop adjusting the support block 14 upward.
[0098] Furthermore, in the above technical solution, the step of obtaining the current image set specifically includes:
[0099] The polarized light source is fixed according to the position of the first light source in the initial image set, and the camera is fixed according to the position of the camera to capture the first current image;
[0100] Based on the position of the second light source in the initial image set, fix the polarized light source and capture the second current image;
[0101] The current image set includes the first current image and the second current image.
[0102] Furthermore, in the above technical solution, the specific steps for calculating the installation similarity between the current image set and the initial image set include:
[0103] Calculate the first similarity between the first current image in the current image set and the first initial image in the initial image set;
[0104] Calculate the second similarity between the second current image in the current image set and the second initial image in the initial image set;
[0105] The average of the first similarity and the second similarity is used as the installation similarity between the current image set and the initial image set.
[0106] Furthermore, in the above technical solution, the step of calculating the first similarity between the first current image in the current image set and the first initial image in the initial image set specifically includes:
[0107] Image preprocessing: Preprocess the first current image to obtain image A, and preprocess the first initial image to obtain image B;
[0108] All stress spot contours in image A are denoted as the first stress spot contour set, and all stress spot contours in image B are denoted as the second stress spot contour set.
[0109] Calculate the first normalized central moments of all stress spot contours in the first stress spot contour set and the second normalized central moments of all stress spot contours in the second stress spot contour set.
[0110] The first stress spot contour feature is calculated based on the first normalized central moment, and the second stress spot contour feature is calculated based on the second normalized central moment; wherein, both the first stress spot contour feature and the second stress spot contour feature include the center and the area;
[0111] Calculate the similarity between the contour features of the first stress spot and the contour features of the second stress spot, and use it as the first similarity between the first current image in the current image set and the first initial image in the initial image set;
[0112] The steps for calculating the second similarity between the second current image in the current image set and the second initial image in the initial image set specifically include:
[0113] Image preprocessing: Preprocess the second current image to obtain an image, and preprocess the second initial image to obtain a D image;
[0114] All stress spot contours in image C are denoted as the third stress spot contour set, and all stress spot contours in image D are denoted as the fourth stress spot contour set.
[0115] Calculate the third normalized central moments of all stress spot contours in the third stress spot contour set and the fourth normalized central moments of all stress spot contours in the fourth stress spot contour set, respectively.
[0116] The third stress spot profile feature is calculated based on the third normalized central moment, and the fourth stress spot profile feature is calculated based on the fourth normalized central moment; wherein, the third stress spot profile feature and the fourth stress spot profile feature both include the center and the area;
[0117] Calculate the similarity between the contour features of the third stress spot and the contour features of the fourth stress spot, and use it as the second similarity between the second current image in the current image set and the second initial image in the initial image set.
[0118] The method for finding stress spot contours is the Moore-Neighbor algorithm, which works by finding a black pixel and setting it as your starting pixel.
[0119] Locating a starting pixel can be done in several ways; we will start from the bottom left corner of the grid and scan each column of pixels from bottom to top, from the leftmost column to the right, until we encounter a black pixel, which we will take as our starting pixel.
[0120] Each time a black pixel P is encountered, backtracking is performed, that is, returning to the white pixel where it was previously standing, and then bypassing pixel P in a clockwise direction, visiting every pixel in its mole neighborhood, until a black pixel is hit.
[0121] This process is repeated until the starting pixel is visited a second time, at which point the algorithm terminates. The black pixels traversed during the entire process become the boundary pixels of the target. The traversed black pixels form the outline of the pattern.
[0122] Furthermore, in the above technical solution, the similarity between the first contour feature and the second contour feature, as well as the similarity between the third contour feature and the fourth contour feature, are calculated using the cosine similarity calculation method.
[0123] Cosine similarity, also known as cosine similarity, assesses the similarity between two vectors by calculating the cosine of the angle between them. Cosine similarity plots vectors in a vector space, such as the most common two-dimensional space, based on their coordinates; it measures the similarity between two vectors by measuring the cosine of the angle between them. In this scheme, the center and area of the contour feature are used as vectors, and the cosine of the angle between the two vectors is calculated as the similarity.
[0124] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention.
