Operation Requirements In The Practical Use Of H Steel Web

Apr 24, 2018

The steel web used in the project is made of H steel. Considering the characteristics of the H steel, what should be paid attention to when the steel web is used for support?

First of all, we should calculate the size section of the box beam, and make the steel web with the steel pipe to control the section shape of the box girder, and then combine the steel web with the screw and the inner support to combine each steel web and welding. It is important to note that the steel web should be corrected in time before and after welding to keep the upper edge of the steel web in a straight line; and at the same time, the steel web is kept on a straight line. It should be adjusted by the external support rod, the rod screw, the inner support and the big head wedge.

At the same time, due to the large steel web, it is necessary to pay attention to the correction of steel webs to make the steel web longer and affect the position of the diaphragm, and the position of the diaphragm must be strictly controlled. In addition, the lateral overall size and bolt hole size of each wave plate section should be strictly controlled. The relative tolerance of intersections of each segment should be controlled within the allowable range to ensure the smooth connection.
