双拱形空间堆焊耐磨板结构是应用大跨度空间结构设计理念并结合仿生学而提出的一种新型结构,该结构具有刚度大、用钢量省、传力路径明确及节点设计简单等优点。
Double arch space surfacing wear-resistant plate structure is a new type of structure based on the design concept of large-span space structure and bionics , The structure has the advantages of large stiffness, less steel consumption, clear force transmission path and simple joint design.
计算表明比普通的闸门结构节省了约30%的用钢量。本公司就基于已建的双拱钢管闸门对双拱结构进行了研究。首先就这种结构的渊源进行探讨,介绍了双拱空间结构的概念是如何提出的,与传统的实腹梁以及普通桁架结构进行比较,体现出了双拱结构的优势,并介绍了双拱形空间钢管结构在挡潮泄洪闸门中的应用情况。
The calculation shows that it can save about 30% compared with the ordinary gate structure % The amount of steel used. The company has studied the double arch structure based on the built double arch steel pipe gate. Firstly, the origin of this structure is discussed , How to put forward the concept of double arch space structure is introduced , Compared with the traditional solid web beam and ordinary truss structure , It shows the advantages of double arch structure , The application of double arched spatial steel pipe structure in tide gate is introduced.

之后对双拱结构的参数及形状进行了优化,包括布置榀数、双拱的线型及双拱的厚跨比等,考虑荷载、端跨比、跨度及弦杆等因素的影响。同时根据优化的结果,制定了可查询的设计表格,给设计人员提供了初步设计的依据。进一步将堆焊耐磨板双拱结构引入到平板闸门与人字闸门的设计中,并对应用时的参数进行了分析。钢管结构由于其独特的优越性能被广泛应用于空间结构中。
Then the parameters and shape of the double arch structure are optimized , Including the number of layout, the line shape of double arch and the thickness span ratio of double arch , The effects of load, end span ratio, span and chord are considered. At the same time, according to the optimization results , The design table that can be inquired is made , It provides the basis of preliminary design for designers. Furthermore, the double arch structure of hardfacing wear-resistant plate is introduced into the design of flat gate and miter gate , The application parameters are analyzed. Steel tube structure is widely used in space structure because of its unique superior performance.
随着多维数控切割技术和钢管结构专用设计软件的发展,钢管构件之间的连接越来越多地采用相贯节点型式。堆焊耐磨板在空间结构中的应用越发广泛。相贯节点在荷载作用下,支管与主管的相贯连接面发生局部变形,从而引起相对位移和转动,无论在弹性或弹塑性阶段都表现出不同于铰接也不同于刚接的特性,这种节点的半刚特性对双金属耐磨板结构的受力、变形及整体稳定性都有显著的影响。
With the development of multi-dimensional numerical control cutting technology and special design software for steel pipe structure , More and more tubular members are connected by intersecting joints. Hardfacing wear-resistant plate is widely used in space structure. Under the action of load , Local deformation occurs at the intersection of branch pipe and main pipe , This causes relative displacement and rotation , Both in the elastic and elastic-plastic stage, it is different from the hinged joint and the rigid joint , The semi-rigid behavior of the joint has a significant effect on the stress, deformation and overall stability of the bimetal wear-resistant plate structure.
