The utility model relates to an oblique well type frame beam, belonging to the construction field, in particular to the structural arrangement of a long span type well frame beam when the ratio of the long edge and the short edge of the building is about 1.25 to 1.5. Building long side span number control for N equal span, short side spans of control for building the corresponding aliquots of N-1 span, each span is 6m ~ 8m, the layout of frame column in the construction side of the axis of long and short side of the points, the frame beam placed on the construction of long and short side and the long side and short side of the building points on the diagonal line, both ends of frame beam to column frame beam section height for building high, short span of 1/15 ~ 1/18. The utility model solves the problem that the layout of a general well shaped frame beam is large, the height of the beam cross section is big, the reinforcement difference is great, and the strength of each heel beam can not be fully utilized, and the transmission force is unitary. By adopting the structure arrangement method, the height of the beam cross section is lowered, and the function of each beam is fully brought into play, the structural force transmission path is increased, the building is beautiful, and the utility model has good economic benefit and use value.
【技术实现步骤摘要】
本技术属于建筑领域,尤其涉及大跨度井字框架梁的结构布置。
技术介绍
大跨度楼盖采用井字梁结构方案时,当建筑的长边与短边之比约为1 1,采用与轴线平行布置的井字梁结构,可以获取比较经济合理的结构;但是当建筑的长边与短边之比为1. 25 1. 5时,再采用与轴线平行布置的井字梁结构,往往长边的梁得不到充分的利用,而短边的梁需要很高的截面,不经济,结构受力不合理;抗震方面,结构短向刚度大,长向刚度低,对抗震也不利。
技术实现思路
为解决现有与轴线平行布置的井字梁结构技术的不足,通过研究我们发现当采用双向斜向布置时,梁截面高度减少,每跟梁充分发挥其强度,荷载通过梁的传递路径增多, 结构受力合理;抗震方面,增加了短向与长向的联系,对抗震有利,即采用一种斜向井字框架梁的结构布置。本技术的技术解决方案是这样实现的建筑的长边与短边之比近似为 1. 25 1. 5,建筑长边跨数控制为等分N跨(N = 5,4,3),相应建筑短边跨数控制为等分N-I 跨,每跨跨度为6m 8m,框架柱布置于建筑边轴线长边与短边的等分点,框架梁布置于建筑长边与短边和建筑长边与短边等分点交线对角线上框架梁两端均交于柱,框架梁等高, 截面高度为建筑短边跨度的1/15 1/18。本技术的有益效果是这种结构布置方式,将使梁截面高度降低,充分发挥每根梁的作用,结构传力路径增多,建筑美观,具有良好的经济效益与使用价值。以下结合附图和具体的实施方式对本技术做进一步的描述。附图说明图1为传统的与轴线平行布置的井字梁结构局部布置图。图2为图1所示结构布置的混凝土构件配筋及钢构件应力比简图。图3为本技术结构局部布置 ...
