Abstract
Description
TECHNICAL FIELD
[0001] The present application relates to the technical field of thin stone installation, in particular to a stress balance installation method of a thin stone dry hanging system without keel. BACKGROUND
[0002] The thin stone dry hanging system without keel is a relatively new stone installation technology that is becoming increasingly popular in building curtain walls and indoor and outdoor decoration. It is significantly different from the traditional stone dry hanging system (which usually requires a complex steel keel support structure). Specifically:
[0003] Natural stone (such as granite, marble, limestone, sandstone) or artificial stone with a thickness of usually between 10mm and 30mm is used. This is much thinner than the traditional 30mm-50mm thick curtain wall stone, greatly reducing the weight (usually by 50%-70%). The complex steel keel frame behind is cancelled. The stone panel is fixed directly on the structural base layer of the building (such as concrete wall, masonry wall or light steel keel wall after strengthening treatment) through special connectors. The dry hanging method, i.e. using mechanical anchoring (such as back nails, butterfly buckles, SE hanging pieces, etc.) to fix the stone and the connector, does not use cement mortar and other wet work adhesives, ensuring the convenience, adjustability of installation and the ventilation and drainage performance of the curtain wall.
[0004] During the installation of the thin stone dry hanging system without keel, stress is one of the key concerns, especially at key structural locations (such as corners, hole edges, closing points, near structural expansion joints, large-span areas, etc.). Unbalanced stress distribution can cause hole wall cracks, panel bending and cracking, etc. at the hanging points, seriously affecting the quality and service life of the entire curtain wall.

[0085] Example 1:
[0086] refer to Figure 1 The technical solution provided by this invention is: a stress balance installation method for a thin-walled stone cladding system without a keel, the method comprising:
[0087] Step 1: Acquire measurement data from multiple measuring points within the target area, and use the acquired measurement data to perform real-time stress state calculations, including the following steps:

[0091] A sensor is arranged at each measuring point to measure the measuring data of each measuring point, including the strain, vibration acceleration, connector stress, and plate joint deformation of the stone;
[0092] The stress of the measuring point is calculated ; wherein, represents the elastic modulus of the stone; represents the measuring point The strain of the stone; represents the thermal expansion coefficient of the stone; represents the measuring point The temperature change of the stone at the measuring point.
[0093] Step 2, obtaining the stress state calculation result, diagnosing the calculation result, identifying the stress imbalance type of the measuring point, including the following steps:
[0094] The stress of the measuring point is clustered and analyzed by the DBSCAN clustering algorithm, and the clustering result is output, including:
[0095] The stress of all measuring points is obtained, and after standardization processing, the measuring point stress value set is constructed ;
[0096] The neighborhood of each measuring point is calculated , wherein the allowed stress fluctuation bandwidth ; represents the stress value of the measuring point ;
[0097] If , a new cluster is created and the neighborhood is expanded, wherein ; represents the minimum point cluster;
[0098] The expansion area includes: if , the measuring point is added to the current cluster;

[0100] The clustering result is ; wherein, represents the th cluster; represents noise; represents the noise set; represents the stress classification set; represents the number of noises;
[0101] Analyze the clustering results, including:
[0102] Extract the cluster center, cluster radius and cluster density, and make imbalance type judgment, including:
[0103] Cluster center ; Cluster radius ; Cluster density ; Wherein, ;
[0104] If, , the stress imbalance type is judged as local stress concentration, the noise point exceeds the threshold range, and there is a risk of hole edge cracking; wherein, The average stress value is represented by ; Stress value standard deviation;
[0105] If, , the stress imbalance type is judged as regional stress imbalance; there is a risk of stone slab warping deformation. Wherein, stress gradient , Maximum allowable stress of stone ;

[0110] If it is regional stress imbalance, adjust the overall flatness or modify the stone plate joint width.
[0111] The internal relationship of the above three types is that when regional stress imbalance occurs, stress redistribution is caused, and stress redistribution leads to local stress concentration and compression type imbalance. That is, when regional stress imbalance occurs, compression type imbalance usually occurs, regional stress imbalance occurs alone or at the same time.
[0112] Therefore, the embodiment focuses on the process of guiding the installation when regional stress imbalance occurs.
[0113] If regional stress imbalance occurs,
[0114] Considering the interval stress coupling effect, the leveling parameters are obtained, and based on the leveling parameters, the adjustment strategy capable of guiding the installation is generated, including:

[0123] The constraint condition of the objective function is that the adjustment displacement amount of each region is not higher than the highest allowed displacement amount ;
[0124] Solve the objective function by the interior point method to obtain the optimal displacement vector ; Satisfy the convergence condition ;

[0127] Set the adjustment strategy priority rules, including:
[0128] , preferentially adjust the boundary points of the region, and then adjust the internal points; , preferentially adjust the internal points and then adjust the boundary points of the region. Synchronously adjust the non-coupling region. The so-called non-coupling region is that the ratio of the coupling stiffness matrix elements corresponding to the two regions is less than 0.1, that is: .
[0129] For example, in the construction process of a curved curtain wall, leveling (Y=36) is required, and the imbalance degree of the corner area is 0.32; the imbalance degree of the center area is -0.18; it is judged that the imbalance index of the corner area is greater than zero, and the imbalance index of the center area is less than zero.
[0130] Solve the objective function to obtain the adjustment displacement amount of the corner area as -1.8 mm; the adjustment displacement amount of the center area is +0.9 mm; the corner area preferentially adjusts the internal hanging points; the center area preferentially adjusts the boundary hanging points.
[0131] Convert the execution instructions to calculate the torque of the adjustment tool (electric drill) and adjust the corresponding hanging points in turn.
[0132] The above leveling process actually also solves the problem of local stress concentration, that is, loosens the corresponding hanging points or adds shims.
