如何防止钢结构厂房基础下沉?

天物彩板专注彩板行业16年——吉林钢结构厂房原材料彩涂卷生产厂家详细请拨打网站上方电话咨询

如何防止钢结构厂房基础沉陷需要从基础承台开始。当钢结构厂房达到每平方米25kg/m时,基础承台需要达到1m高、1m宽、1m深。当钢结构厂房达到每平方米35kg/m时,需要制作环梁和1.2m基础。具体细节还需要根据地面情况而定。
钢结构厂房施工完成后,没有前期投资,如何防止钢结构厂房基础下沉?简言之,就是强化。所有钢结构柱均用工字钢或槽钢围成网状。这种方法可以防止钢结构厂房的地基沉陷。

如何防止钢结构厂房基础沉陷?
近年来,钢结构厂房以其重量轻、抗震性能优越、结构布置灵活、加工安装速度快等优点在煤炭工程中得到了广泛的应用。本文仅讨论门式刚架轻钢结构和钢排架结构的单层厂房(以下简称钢结构厂房),其围护结构为压型钢板或夹芯板。
对于大型吊车吨位的钢结构厂房,由于上部结构重量轻、柱底轴力小、弯矩相对较大,地基偏心度过大,给基础设计带来了一定的困难。

How to prevent the foundation sinking of steel structure workshop needs to start from the foundation bearing platform. When the steel structure workshop reaches 25kg per square meter, the foundation bearing platform needs to reach 1m high, 1m wide and 1m deep. When the steel structure workshop reaches 35kg per square meter, the ring beam and 1.2m foundation need to be made. The details also need to be based on the ground conditions.

When the construction of the steel structure workshop has been completed, and there is no early investment, how can we prevent the foundation of the steel structure workshop from sinking? In short, it is reinforcement. All the steel structure columns are surrounded with I-steel or groove steel to form a network. This method can prevent the foundation sinking of steel structure workshop.
How to prevent the foundation sinking of steel structure workshop?
In recent years, steel structure workshop is widely used in coal engineering because of its light weight, superior seismic performance, flexible structure layout, fast processing and installation speed. This paper only discusses the single story factory building with portal frame light steel structure and steel bent structure (hereinafter referred to as "steel structure factory building") whose enclosure structure is made of profiled steel sheet or sandwich panel.
For the steel structure workshop with large crane tonnage, due to the light weight of the upper structure, small axial force at the bottom of the column and relatively large bending moment, the eccentricity of the foundation is too large, which brings some difficulties to the foundation design.
