文档介绍:单层厂房
The Single-story Factory Building
Introduction
The property of the factory building
(单层厂房的特点)
Long span, great height, great loads;
Dynamic loading;
Clear structure with little partings and walls;
The foundations ensure great loads.
Classifications
Divided by materials
1. Hybrid structures;
2. Reinforced concrete structure;
3. Steel structure.
Divided by structural forms:
Row frame: consist of roof, columns, and foundations, the column is connected to roof with hinges and to the foundation with fixed ends;
Rigid frame: consist of beams, columns, and foundations, the column is connected to roof with fixed ends and to the foundation with hinges.
Frame structures
constitutes and placements
The constitute of the structures
Roof structure
Lateral plane frame
Longitudinal plane frame
The placements of the structure
The plane and section placements
1. The location axis
2. The placement of columns
在厂房端部横向定位轴线与山墙边缘重合,将山墙内侧第一排柱中心内移500mm;伸缩缝两边的中心线向两边移动500mm.
柱网的布置应符合《厂房建筑模数协调标准》GBJ6-68
跨度在18M和18M以下时,采用30M的模数;
跨度在18M以上时,采用60M的模数;
3 The plane placement of the structure
单层厂房的平面布置包括柱网布置,吊车梁,维护墙布置,屋面梁,天沟板布置,基础与基础梁布置等。
4 The deformation gaps
变形缝包括伸缩缝、沉降缝和防震缝三种。
1)伸缩缝(temperature gap)结构体系很长时,温度应力过大。通过设置伸缩缝来解决。
最大伸缩缝间距:处于室内或土中 100M
处于露天时 70M
2)沉降缝(settlement gap):解决不均匀沉降问题。
3)防震缝(Seismic gap):当建筑物平面、立面复杂,结构高度或刚度相差很大时。
