Description

一种核心筒斜墙施工的钢平台变形施工结构及方法 技术领域
本发明属于建筑施工技术领域,特别涉及一种核心筒斜墙施工的钢平台变形施工结构及方法。
背景技术
超高层建筑大多设置核心筒结构,在实际施工中,通常采用减少核心筒墙厚或者减少核心筒数量的形式设置核心筒,以提高经济效益,同时兼顾设计要求。然而,若采用减少核心筒数量的方式,会出现刚度突变的情况,会影响核心筒整体抗侧力和抗震能力。面对前述问题,可以选择核心筒斜墙收分的柔性变化方式来减少对核心筒整体受力体系的影响。然而,核心筒斜墙收分的模式,由于存在斜墙段,传统直上直下的钢平台的施工模式会面临以下问题:
一是由于核心筒斜墙的收分,
施工墙体为斜墙,当前施工楼层会产生较大的水平荷载,单靠模板自身无法抵抗,若不加处理,会使墙体挠度过大。
二是由于施工墙体为斜墙,在模板提升的工况下,一旦拆除对拉螺栓等模板与结构墙体的固定,墙体内部模板在提升装置的作用下,会形成类似单摆的机构,由于模板质量较大,摆动起来会有较大动能,若撞击到内筒架上,则会对内筒架以及内筒架上的人员造成巨大伤害,造成安全事故隐患。
因此,如何提供一种核心筒斜墙施工的钢平台变形施工结构及方法,是本领域技术人员亟需解决的技术问题。
公开于该背景技术部分的信息仅仅旨在增加对本发明的总体背景的理解,而不应当视为承认或以任何形式暗示该信息为本领域一般技术人员所公知的现有技术。
发明内容

为解决以上技术问题,本发明包括如下技术方案:
一种核心筒斜墙施工的钢平台变形施工结构,包括:钢平台,所述钢平台沿核心筒剪力墙横截面延伸;所述钢平台包括顶梁、底梁、内筒架和外挂架,所述内筒架的上下两端分别与所述顶梁和底梁固定连接,所述内筒架通过位于其底部的钢牛腿支撑于核心筒剪力墙的预留孔中;所述外挂架悬挂于所述钢平台顶梁下方且能够沿着钢平台顶梁下端的脚手架轨道滑动;
