What problems should be paid special attention to in the installation of steel structure engineering?

1. Steel column support has clearance risk control methods. Before steel column hoisting, steel structure engineering installation should strictly control the design elevation and measurement of the foundation, and carefully level the foundation surface according to the measured value; If the secondary grouting method is used, the irrigation hole (as the vent hole) is opened on the bottom plate of the column foot, the steel plate pad is used to smooth the bottom of the steel column, the column foot support steel is set in advance according to the overall planning elevation, and then the secondary grouting is carried out.

2. Risk control method of excessively large linear deviation of steel structure engineering column Steel column should be hoisted in place according to the calculated hoisting point, and more than two points of hoisting method should be selected. Lifting should be temporarily stable to prevent lifting deformation; Temporary support points should be added as soon as possible after the column is in place; Straight line deviation should be corrected before stabilization.

3. Steel column displacement risk control method Before pouring concrete foundation, the embedded bolts are stuck with forming chucks in the overall planning direction to prevent displacement during irrigation of concrete; The reserved hole of the column low steel should enlarge the sample, and the hole should be reserved after determining the hole location.

4. After the column and beam installation, in order to facilitate the construction of steel structure projects such as column bolts, it is necessary to lay an appropriate number of passage plates on the steel column. Storage welding machine, air compressor, acetylene bottle and other equipment platform should be installed on the newly installed steel column. The placement spacing is in line with the relevant provisions of safety production. In order to facilitate the high-altitude operation of steel structure engineering construction, the steel ladder should be stabilized on the steel column before the davit. In order to implement the column and beam joints conveniently and quickly, the hanging basket feet should be installed.

5. The motors and equipment used in engineering construction shall be grounded, and glass shall not be used. Damaged wires and cables should be strictly prevented from leaking equipment. The electrical equipment and mechanical cables in the construction of steel structure engineering should be gathered together and gradually rise with the construction of each floor. Each floor must set up its own distribution box to meet the construction electricity needs of each floor. When the wind speed reaches 15 m/s in the construction process, special attention should also be paid to fire safety, providing the necessary fire equipment and fire safety supervisors.
