钢结构工程施工方案

Steel Structure Construction Scheme

一、钢结构工程概述

A brief account of steel structure work

本工程为斯比克（中国）工业设备制造有限公司之汾湖新厂房项目钢结构工程。分A-1和A-2两个单体，其中A-1屋面面积3.4万平方米，A-2屋面面积1.5万平方米。

生产车间内设有桥式桁车，钢柱、钢梁采用焊接成型的H型钢，结构主材采用Q345B，檩条采用Z型钢，墙面采用双层压型钢板+保温棉的构造，屋面采用钢承板+保温板+柔性防水卷材的构造。

The working area of steel structure work are production and warehouse halls, bicycle shed, total area is about 16500 square meter, roof pitch is 5%, eave height 13.75M. There will be 6 8t bridge traveling cranes in production hall, welding H-section steel column and beam, structural main material is Q345B, cold bending sheet steel Z-purlin, wall and roof cladding are double-skin pressed steel sheet and thermal insulation wool.

二、钢结构工程的特点

Characteristic of steel structure work

1、该工程单坡最大跨度为18m，钢柱高度大，单榀框架的平面外刚度极小，吊装过程中做好保证结构平面外的稳定作为安全技术控制的重点。

The single span of the work is 18m, the height of steel column is large, single frame plane external rigidity is very small, so the key point of safety technical control is to guarantee the stability outside the structural plane.

2、厂房最大连续24跨，长度方向252m，制作安装时应注意误差累计，做好测量控制点，保证整个厂房的安装精度。

Take out 6 steel columns from grid line 9~14 in the production building, instead of 52.5m space truss as trimmer beam to support the upper structure and crane load, the installation of the space truss is a difficulty point of this work.

三、施工现场总平面布置方案

施工现场平面布置方案大体与土建单位一致，在土建单位搭设的临时设施内进行钢结构安装。

三、钢构件的制作

Fabrication of steel structural members

（一）、制作前的技术准备

Technical preparations prior fabrication

1、钢结构制作前必须熟悉设计的施工图，了解设计要求，并审核图纸，根据蓝图编制加工制作图，并在得到原设计部门的认可后方可进行备料加工。

Study and check the design working drawing before fabrication, make shop drawing and get approval from designer then prepare material for fabrication.

2、根据构件类型、数量、用材制定加工计划和加工程序。

Make a plan and program for fabrication as per the type, quantity and material of the structural members.

3、编制施工工艺和技术措施，以及对加工用的设备制定检查维护计划，使机械设备

处于良好状态。

Write construction techniques and technical measures, and the equipment regular examine and maintain plan, keep the machinery in good condition.

（二）、主材采购计划

Material requirements:

1、对工程用的材料应进行选定和确认。

Select and confirm the material for the project.

2、各种材料均应有质量证明书和出厂合格证。若有疑议则应按国家有关标准的规定进行抽样检验，经检验合格后方可批量使用。

All kinds of material should be with quality guarantee and ex-factory certificate. If there is any doubt, sampling examination should be taken according to relevant national standard, only when passed the examination material in batches can be used.

3、钢材表面锈蚀等级应符合现行国家标准《涂装前表面锈蚀等级和除锈等级》规定。

Rust degree of steel surface should conform to the present national standard .
