Problems solved by technology

[0005] In the prior art, when an earthquake occurs at the connection node between the coal transportation trestle and the transfer station, because the coal transportation trestle and the transfer station are connected together by bolts, the coal transportation trestle can only be connected to the steel girder of the transfer station along the direction of the long hole. The sliding of the roof makes the coal trestle or transfer station easy to be damaged when an earthquake occurs. Therefore, the connection between the coal trestle and the transfer station has certain safety hazards

Abstract

The invention discloses a trestle support leg slide node and belongs to the field of steel structures. The trestle support leg slide node has the advantages that the trestle support leg slide node utilizes a first plate, a second plate and a limit part, the first plate is arranged on the top plate of a transfer station steel beam, the second plate is arranged on the bottom plate of a trestle support leg, the limit part is arranged on the top plate or the bottom plate, or part of the limit part is arranged on the top plate and the other part of the limit part is arranged on the bottom plate, the second plate is limited by the limit part to move on the first plate, the limit part is used to replace the coordination of elongated holes and bolts in the prior art, the second plate can slide inoptional directions on the first plate, and accordingly the trestle support leg can slide in optional directions on the transfer station steel beam, mutual containment between a trestle and a transferstation during an earthquake is avoided, potential safety hazard of connection between the trestle and the transfer station is eliminated, and structure safety is increased.

Description

technical field [0001] The invention relates to the field of steel structures, in particular to a sliding joint of trestle legs. Background technique [0002] The principle of power generation in a thermal power plant is to burn coal to heat the boiler, so that the water in the boiler turns into water vapor, and the water vapor drives the turbine generator to generate electricity. The coal handling system is an important part of a thermal power plant, mainly including coal storage yards, coal handling trestles and transfer stations, etc. How to ensure the stability of the connections between the various components in the coal handling system plays a very important role in the smooth progress of thermal power generation important role. [0003] In the prior art, the connecting node between the coal transportation trestle and the transfer station is provided with long holes corresponding to both sides of the bottom plate of the outrigger of the coal transportation trestle and...
