装配整体式空间钢网格盒式结构小高层住宅的经济性分析

Economical efficiency analysis of the assembled monolithic space steel grid box structure of small high-rise residential building

随着我国钢产量的迅速增加,高层钢结构住宅也得到了快速的发展,但是这仅局限于高层钢框架结构住宅的发展。高层钢框架结构住宅有着许多的不足之处,即造价高、构件大而重,运输、安装难度大,施工现场需电焊和房间划分不灵活等问题。针对以上这些问题,本文介绍了一种新型钢结构住宅体系———装配整体式空间钢网格盒式结构。这种结构体系主要由钢空腹网格大板楼盖和钢网格式承重墙架组成,具有三维受力的特性;空腹楼盖具有跨度大、自重轻等优点,室内无梁无柱,自由划分居室,使用方便、美观,节约层高;钢网格墙采用DQ轻质板材包裹,不需再作防火防锈处理,而且还有良好的保温效果。本文通过一拟建工程为例,对比分析了盒式结构与常规钢框架结构,研究表明盒式结构在很大程度上优越于钢框架结构。

With the rapid increase of output of our country steel,high rise steel structure housing has also been a rapid development,but it is confined to high rise steel frame structure of residential development.High rise steel frame structure house has many deficiencies,It has high cost,its Components is large and heavy,it is difficult to transport and install,the construction site needs welding and the room division is not flexible.To solve these problems,this paper introduces a new type of steel structure housing system,called assembled monolithic space steel grid box structure.This kind of structure system is mainly composed of steel Vierendeel grid slab floor and steel grid wall frame,with three-dimensional mechanical properties;The steel vierendeel grid slab floor has the advantages of large span,light weight;It can be free to decorate the room without the beam and column,it is easy to use,appearance,save height.Steel grid wall is wrapped by DQ light plate,there is no longer to do fireproof and anticorrosive treatment and it has the good heat insulation effect.In this paper,through a proposed project for example,it compares the box structure with conventional steel frame structure,the study shows that the box structure is superior to the steel frame structure.
