Stone curtain wall selection and mechanical calculation
In the design of the curtain wall, detailed structural details should be drawn according to the size, color and material of the stone, and then the mechanical verification of the seismic resistance, compression and other related parameters of the relevant nodes should be completed according to the relevant design specifications to ensure the application of the stone curtain wall. Safety and stability. Conventionally, in the selection of stone, according to the characteristics of the stone curtain wall indoors and outdoors, according to the elevation map and the detailed map of each node, mechanical calculations are made for various parameters such as strength, water absorption rate and seismic resistance level to determine the stone. Selection, priority should be given to the characteristics, color, physical properties and texture of the stone products, and at the same time combined with the curtain wall's grid form, construction cost, design layout and other requirements to reach the best overall design of the stone. In the design of high-rise curtain wall, in the calculation of the mechanical properties of the stone curtain wall related nodes, it is necessary to complete the mechanical calculation of the curtain wall system in combination with the structural mode, connection method, material properties and national industry behavior standards of the curtain wall design. The main ones can be divided into the following aspects: (1) Determination of the load to be carried. Generally, when determining the load, it is necessary to consider the stone's own weight, wind load, seismic load, and other forms of load to maintain the effective transmission of structural loads. For uncertain loads, it can be determined according to national standard calculations and simulation tests. (2) Calculation of stone force. Before calculating the force of the stone, it is necessary to determine the load form of the stone and the dry hanging method of the stone, thereby determining the calculation model of the stone curtain wall, and calculating the weight bearing mode and safety of the stone curtain wall. In addition, it is necessary to analyze the stress of the stone itself, including the physical properties of the stone and various indicators, and calculate according to the safety factor of different stone properties. (3) Checking the bending and shear resistance of stone. For anisotropic stone, the bending check of the stone curtain wall related plate can be divided into two cases. One is that the point where the maximum bending stress occurs in the stone plate is zero in the other direction, as long as the maximum stress is less than the corresponding direction. The stone allows the stress to meet the requirements of the stone plate itself, and vice versa. Second, the point at which the maximum bending stress occurs in the stone plate is not zero in the other direction, and the stress should also be considered at the same time. At this time, the internal friction theory can be applied for checking. When checking the shear resistance of stone, it is necessary to check the calculation according to the calculated thickness and hole depth of the stone.
