水泥储存罐是建筑工地必备的设备之一,其重量全部由支架承担,储存量在45吨以上的水泥罐支架主要部分的结构,通常按经验比较法设计成图1所示,但经验比较法设计的水泥储存罐支架往往因保守而浪费材料,造价高。本文推荐采用力学计算法设计水泥储存罐支架,在保证工作安全可靠的情况下,用力学计算法设计比用经验比较法设计可节省材料约30%。现以设计一自重5吨、储存水泥50吨水泥罐支架为例,其设计计算如下: 1.t实际结构的力学简化
The cement storage tank is one of the necessary equipment for a construction site, and its weight is entirely borne by the support. The structure of the main part of the cement tank support with a storage capacity of over 45 tons is usually designed according to the empirical comparison method as shown in Figure 1, but experience comparison Law designed cement storage tank bracket is often conservative and waste materials, high cost. In this paper, the mechanical calculation method is recommended to design cement storage tank bracket, in ensuring the safety and reliability of the work, the mechanical calculation method design than the experience of comparative design can save about 30% of the material. Now to design a deadweight of 5 tons, 50 tons of cement storage tank cement tank stent, for example, the design calculations are as follows: 1. t Mechanical simplification of the actual structure
