[0002] With the rapid development of social economy, stone curtain wall installation is the core technology for building facade decoration. Its necessity is mainly reflected in three aspects: First, in terms of safety, the curtain wall system forms a flexible connection between the stone and the building main body through metal keels and hangers, and its seismic performance is superior to the traditional wet pasting process (it can resist an acceleration of 0.4g as measured in areas with a seismic fortification intensity of 8 degrees). Second, in terms of durability, a 6 - 8mm ventilation cavity can effectively discharge condensed water, avoid freeze - thaw damage, and extend the service life of the stone to more than 50 years (tracking data of Beijing China World Trade Center Phase III shows zero detachment in 25 years). Finally, in terms of process adaptability, the installation error can be accurately adjusted by ±15mm to meet the inter - layer displacement compensation requirements of super - high - rise buildings (such as the 126 - storey Shanghai Tower).

[0003] However, for the existing atrium stone curtain wall installation, generally, after manually measuring the dimensions and adjusting the keel dimensions, the stone is installed on the keel.

[0045] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0046] Example 1

[0047] See also Figures 1-5 , an auxiliary stone dry hanging method includes the following steps:

[0048] Laser scan the dry-hanging position, obtain the dimensional data of the scanned dry-hanging position, transfer the dimensional data of the scanned dry-hanging position into 3D software, and generate dimensional drawings;

[0049] Obtain architectural drawings and obtain the dimensional data of the dry-hanging position drawings according to the architectural drawings;

[0050] Set the error range threshold, compare the dimensional data of the dry-hanging position with the dimensional data of the dry-hanging position drawings to obtain the error range value. When the error range value is not included in the error range threshold, determine whether the dimensional data of the dry-hanging position is accurate according to the prediction of the dry-hanging position;

[0051] When the dimensional data of the scanned dry-hanging position is determined to be incorrect, predict and calculate the dimensional data of the dry-hanging position based on the architectural drawings, and appropriately modify the dimensional data of the scanned dry-hanging position to obtain the modified dimensional data of the dry-hanging position;

[0052] Manufacture PVC boards according to the modified dimensional data of the dry-hanging position, compare the dry-hanging position on-site through the PVC boards, and confirm or modify the dimensional data of the dry-hanging position again;

[0053] Manufacture wooden templates by reconfirming or modifying the dimensional data of the dry-hanging position, install the wooden templates and extend them to the dry-hanging position, select the best installation position, so that the gap between one end dimension of the wooden template and the dimensional data of the dry-hanging position is uniform;

[0054] Cut the light steel keel according to the dimension extended by the wooden template, install the cut light steel keel, and remove the wooden template;

[0055] Install the stone according to the installation position of the light steel keel, so that the stone is parallel to the light steel keel to complete the installation.

[0056] For the existing atrium stone dry-hanging, generally, after manually measuring the dimensions and adjusting the keel dimensions, the stone is installed on the keel. Manually measuring the dimensions requires a lot of time. And since the stone is perpendicular to the dry-hanging position, for aesthetics, it is necessary to adjust the gap between the stone position and the building surface beautifully to ensure that the overall gap is uniform, so as to improve the overall aesthetics of the subsequent floor tile paving and guardrail installation. However, the existing stone dry-hanging method cannot improve the aesthetics and fast installation effect after installation;

[0057] According to Figure 1As shown in the figure, a laser scanner is used to scan the dry-hanging positions to obtain the dimensional data at the dry-hanging positions. Among them, a ground-based laser scanner (such as Faro / Leica) is selected for laser scanning. For irregular walls such as arcs and curved surfaces, 3D laser scanning can quickly obtain point cloud data with millimeter-level accuracy, generate a real curved surface model, assist in keel positioning and stone layout, avoid traditional measurement errors, and the 3D model generated after scanning can automatically analyze the flatness deviation of the wall surface (needs to meet the standard of ≤3mm), identify the areas to be repaired, and ensure that the dry-hanging base meets the construction requirements;

[0058] Based on the point cloud model, mark the positions of the embedded parts and the welding points of the keels, and guide the installation of channel steel / angle steel to ensure that the specifications such as the main keel spacing ≤1.2m and the weld height ≥4mm are met;

[0059] It should be noted that CloudCompare / PolyWorks point cloud processing software;

[0060] Transfer the obtained dimensional data of the dry-hanging positions into a 3D software to generate dimensional drawings. Subsequently, obtain the dimensional data of the dry-hanging position drawings through the architectural drawings, compare the dimensional data of the dry-hanging positions with the dimensional data of the dry-hanging position drawings to obtain the error range value. When the error range value is not included in the error range threshold, determine whether the dimensional data of the dry-hanging positions is accurate according to the prediction of the dry-hanging positions, mark the positions of the dimensional data of the dry-hanging positions with larger errors, and determine or modify the dimensional data of the dry-hanging positions through manual measurement by personnel. Compared with the traditional method of wasting a lot of time and efficiency by measuring each position manually, this method obtains the 3D model dimensions through laser scanning, and then quickly locks the dimensional data of the dry-hanging positions that may be misaligned through the error range threshold set by manual experience, so that the manual can go to the site to measure according to these incorrect dimensional data of the dry-hanging positions, thus improving the detection efficiency;

[0061] Make PVC boards according to the modified dimensional data of the dry-hanging positions. Among them, modify the dimensional data of the dry-hanging positions according to manual experience, and obtain various dimensional data of the dry-hanging positions, and process PVC boards according to the various dimensional data of the dry-hanging positions;

[0062] Select the largest dimensional data as the cutting size;

[0063] The remaining dimensional data smaller than the largest selected dimensional data are marked on the PVC board by several engraved marking lines;

[0064] Place the obtained PVC board on the atrium floor, adjust the outermost dimensions of the PVC board according to the outermost boundary line of the atrium floor, and quickly adjust the size of the PVC board by knocking on the marking lines engraved on the PVC board;

[0065] Make a wooden template by reconfirming or modifying the dry hanging position size data, install the wooden template and extend it to the dry hanging position, and select the best installation position so that the gap between the size of one end of the wooden template and the size of the dry hanging position is uniform;

[0066] Cut the light steel keel according to the extended size of the wooden formwork, install the cut light steel keel, and remove the wooden formwork;

[0067] Install the stone according to the installation position of the light steel keel so that the stone and the light steel keel are parallel to each other to complete the installation.

[0068] It should be noted that the dry hanging construction of atrium stone needs to focus on high-altitude safety, structural stability and visual accuracy. The key points include: first, the keel system uses 8# channel steel main keel (spacing ≤1.2m) and 50mm×5mm angle steel secondary keel. Curved atriums over 10 meters need to be combined with three-dimensional laser scanning positioning (error ≤2mm). Second, the density of hanging points is configured according to the size of the stone (when the length is greater than 800mm, each piece has ≥6 hanging points). Thin plates are forced to use back bolts + back strips for composite reinforcement. Third, the patented back bolt connection technology is used to achieve rapid positioning, and sliding T-pieces improve the installation efficiency of special-shaped curved surfaces. The acceptance standard requires the flatness of the base layer to be ≤3mm and the weld height to be ≥4mm. After completion, laser scanning is used to detect the plate seam (5-10mm) and height difference (≤1mm). Regular scanning and monitoring of deformation are required to ensure structural safety. Construction must comply with the "Technical Code for Natural Stone Decoration Engineering". Dry hanging is mandatory for single pieces >40kg or areas >1㎡.

[0069] Furthermore, the pendant installation position is determined according to the architectural drawings and the dry hanging position dimensions;

[0070] When installing the light steel keel, the verticality of the light steel keel is determined by installing the pendant;

[0071] Furthermore, the nodes between every two stones are obtained through the dimension drawings;

[0072] Match the dry hanging position size data with the nodes, predict the nodes that need to be detected through the neural network, and determine the stones at both ends of the node through the nodes;

[0073] Place a ruler on the two ends of the stone that make up the node to check the verticality of the stone;

[0074] If there are multiple dimensions of the dry hanging position to be modified, the largest dimension is selected as the cutting dimension;

[0075] The remaining dimensions that are smaller than the largest selected dimension are marked on the PVC board by several imprinted marking lines;

[0076] When comparing the processed PVC boards on site, the size of the PVC boards can be quickly adjusted by tapping the marking lines printed on the PVC boards;

[0077] Label the areas between or where several marking lines intersect on the PVC board, and upload the PVC drawing;

[0078] After adjusting the PVC board by knocking on the marking lines, determine the removal position through the label, calculate the area at the removed label position based on the PVC drawing, and obtain the perimeter from the area, so as to quickly obtain the modified dry-hanging position dimension data;

[0079] It also includes that the dimension drawing is a 3D model;

[0080] Adjust the 3D model according to the modified dry-hanging position dimension data, and array the light steel keel models on the 3D model to obtain the installation positions of the light steel keels;

[0081] Install the light steel keels at the dry-hanging positions according to the installation positions of the keels;

[0082] It also includes determining the adopted total load value, and calculating the number and distribution positions of single light steel keels according to the total load value;

[0083] The bearing capacity of a single light steel keel includes flexural strength and shear strength;

[0084] Through the stone area and the bearing capacity distribution of a single light steel keel, equal numbers of single keel positions are determined;

[0085] Total load design value: q 总 = 1.2G k + 1.4Q k + 0.6×1.4×W k ;

[0086] G k is the permanent load (self-weight of stone + self-weight of keel);

[0087] Q k is the variable load (such as maintenance load);

[0088] W k is the standard wind load value (to be calculated according to the local wind pressure);

[0089] The calculation of the bearing capacity of a single holding keel is as follows:

[0090] Flexural strength:

[0091] (Simply supported beam model);

[0092] Shear strength:

[0093]

[0094] L is the keel span;

[0095] W is the section modulus of the keel (check the section steel table, for example, for a 50×70 square steel, Wx = 11.16 cm3 Wx = 11.16 cm3);

[0096] f V and f are the design values of the bending / shearing strength of the material (for Q235, take 215 MPa);

[0097] The bolt checking formula is:

[0098]

[0099] A is the area shared by a single bolt, and N is the number of bolts;

[0100] N 设计 is for determining the bolt specification (for example, an M12 expansion bolt is about 6 kN / bolt);

[0101] For example:

[0102] The self-weight of the stone G k = 0.68 kN / m2 (25 mm granite + accessories);

[0103] The variable load G k = 5.0×0.16×0.68 = 0.544 kN / m2;

[0104] The total load design value: q 总 = 1.2×0.68 + 1.3×0.544 = 1.48 kN / m2;

[0105] The keel selected is 50×70 square steel, with a span of 1200 mm;

[0106]

[0107] (safe);

[0108] The area A shared by a single bolt = 1.2×2.4 = 2.88 m 2 (2400 mm horizontally);

[0109] (M12 is safe);

[0110] In summary, determine the strength of the keel and bolts;

[0111] Select the maximum perpendicularity value of the dry-hanging position reference plane for the pendant installation position;

[0112] Radiate and detect the perpendicularity to both sides with the maximum perpendicularity value of the dry-hanging position reference plane as the base point;

[0113] Among them, a radiation length value is set, and the dry-hanging positions detected by radiating to both sides are greater than the radiation length value;

[0114] For example, the selected reference plane of the dry-hanging position is x, and the positions radiating to both sides are x + 2, x + 4, x + 6... x + n, x - 2, x - 4, x - 6... x - n;

[0115] It also includes historical data, and the perimeter trend of the dry-hanging position is calculated through the historical data and the 3D model by a neural network;

[0116] The perimeter trend includes a curve trend, an oblique line trend, and a straight line trend;

[0117] The gap between the stone and the dry-hanging position is covered by tiling tiles.
