Problems solved by technology

[0002] In T-shaped bridge engineering, the connection joint between the flange plate and the diaphragm is extremely important. Once it is damaged under the action of explosion and impact, it will lead to the instability of the entire bridge structure and affect the overall performance of the bridge.
At the same time, the flange plate is the main force-bearing member, and the diaphragm is the connecting part between the T-beams. Explosion and impact can easily cause damage to the T-beam and connecting members, and even cause the bridge to collapse.

Abstract

The invention discloses a protective device and a protective method for anti-explosion and anti-shock of a T-beam connecting member, belonging to the field of bridge engineering. The device comprisesa flange plate, a web plate and a cross diaphragm of a T-shaped beam, wherein a first anti-explosion member is arranged at the lower part of the flange plate, and a second anti-explosion member is arranged on the cross diaphragm; By using the method of superposition of flexible layer and rigid layer, the cushioning of shock wave and the effect of resisting explosive shrapnel and shock are obtainedthrough the combination of different properties of various materials. The device and the method can effectively resist explosion and impact damage, and can be widely applied to the field of T-shapedbridge flange plate and cross diaphragm connection.

Description

technical field [0001] The invention relates to an anti-explosion and anti-shock protection device and a protection method for T-shaped beam connecting members, belonging to the technical field of bridge engineering. Background technique [0002] In T-shaped bridge engineering, the connection joint between the flange plate and the diaphragm is extremely important. Once it is damaged under the action of explosion and impact, it will lead to the instability of the entire bridge structure and affect the overall performance of the bridge. At the same time, the flange plate is the main force-bearing member, and the diaphragm is the connecting part between the T-beams. Explosion and impact can easily cause damage to the T-beam and the connecting members, and even lead to the collapse of the bridge. In view of the uncertainty caused by the explosion, it is necessary to install anti-explosion and anti-shock devices for some weak parts of T-shaped bridges that play an important role,...
