How to improve the installation accuracy of steel structure workshop

In the construction industry, with the use of steel structure workshop more and more popular, steel structure workshop production, transportation and installation technology more and more attention, but also get rapid development and continuous improvement. How to further improve the production and installation accuracy of steel structure workshop and reduce the cost is a subject in front of the steel structure workshop industry. Now the relevant national norms and industry standards have made a lot of provisions in this respect, from parts to the completion of every step have put forward requirements. In order to improve the installation accuracy of steel structure workshop, some problems which must be paid great attention to in manufacture, transportation and installation and some specific control methods are analyzed and summarized. Now cast a brick to attract jade, undertake exchange with colleague.

First, steel structure workshop production and transportation control

The accuracy of the size of the steel structure workshop is the basic and prerequisite to ensure the accuracy of the overall structure and the smooth installation of the steel structure workshop. Therefore, To accurately grasp such as the straightness and distortion of steel column, the distance between the connecting hole of column and beam to the bottom plate, the processing accuracy of the connecting hole itself, the straightness of roof beam and the processing accuracy of the connecting plate of column and beam, the position size of the tie bar or supporting connecting plate relative to the beam and column itself, purlin plate, etc.

Second, the quality control of steel structure workshop installation process

Before the installation of steel structure workshop, all preliminary work should be done earnestly. For example, before hoisting, the installation personnel should retest the components, and only under the premise that the components are not deformed and the installation size is correct, can hoisting be carried out. In addition, on the premise of confirming that the strength of the foundation concrete meets the requirements of the specification, the installation personnel should also test the embedded bolts or cup mouth of the steel column foundation. If the position and elevation size of the foundation are found to be deviated, the position should be recorded to adjust the position of the steel column.

When installing a roof steel frame system, there is sometimes a contradiction between the installation of roof supports and roof purlins. Given that the installation of the envelope and the main structure are often not in the same construction unit, it is necessary to be directed and coordinated by an experienced manager.
