Description

Local through diaphragm plate beam column connecting node

Technical Field

The utility model belongs to the technical field of structural engineering, concretely relates to local diaphragm beam column connected node that link up.

Background

In many high-rise steel structures, the girder steel is mostly H shaped steel roof beam, and the steel column is mostly rectangle steel pipe concrete column. The rigid connection of steel beams and steel columns is the most basic measure for providing the overall rigidity and the seismic performance of the structure. The rigid connection node commonly used at present is that the diaphragm plate is arranged at the position of the steel column corresponding to the beam flange, the internal force of the beam flange is transmitted to the steel column through the diaphragm plate, and the connection mode can provide required rigidity and strength, so that the rigid connection node is formed. The diaphragm plate is provided with an inner diaphragm plate and a through diaphragm plate which are respectively corresponding to two components of a box-type column and a cold-roll forming high-frequency welding rectangular steel pipe column.

The conventional diaphragm plate is arranged on the cross section of the whole column, so that grouting holes and air holes need to be formed in the diaphragm plate in order to conveniently fill concrete in the steel pipe column, and the diameter of each grouting hole is not smaller than 150 mm. In addition, the weakening of the diaphragm by the grout holes cannot be too great for force transmission needs in the nodal region, which limits the section width of the steel column from being too small. In steel structure houses, convex column external corners appear at four corners of each functional room of the houses due to the overlarge cross section of the steel column, and the use function of indoor buildings is affected. Therefore, the width of the section of the steel column is required to be controlled within 300mm, and the whole column section of the diaphragm plate cannot meet the stress requirement. The problems of partition plate stress and concrete pouring in the steel column can be solved simultaneously by adopting the local diaphragm plate.

Based on the technical background, the conventional common partition plate connecting node requires that the section of a steel column cannot be too small, and the common partition plate connecting node is not suitable when the section width of the steel column is smaller.
