Embodiment Construction

[0021] The present invention will be described in detail below in combination with specific embodiments.

[0022] The invention relates to a steel purlin fall prevention conversion device, comprising the existing crown beam 8 and the existing steel purlin 12 in the pile support system of the underground open excavation station, and the existing crown beam 8 and the existing steel purlin A steel wire rope 6 is arranged between 12, and the upper and lower ends of the steel wire rope 6 are respectively fixed to the top of the existing crown beam 8 and the top of the existing steel purlin 12 through fixing components, forming a bridge between the existing crown beam 8 and the existing steel purlin 12. effective connection.

[0023] The top of the existing crown beam 8 is provided with a pre-embedded steel plate 3, which is fixed to the existing crown beam 8 by expansion bolts 2, and the surface of the pre-embedded steel plate 3 is welded with a lifting lug 1 as a fixed node at the...

Abstract

The invention relates to an anti-falling steel purlin conversion device. The anti-falling steel purlin conversion device comprises an existing crown beam and an existing steel purlin which are involved in an underground open-cut station pile support supporting system. A steel wire rope is arranged between the existing crown beam and the existing steel purlin. The upper end and lower end of the steel wire rope are fixed to the top of the existing crown beam and the top of the existing steel purlin through fixing assemblies correspondingly. The existing crown beam and the existing steel purlin are effectively connected. Because existing supporting measures are adopted for replacement of a triangular bracket below the steel purlin, the problem of falling safety of the steel purlin is solved,the space of the triangular bracket below the steel purlin is saved, and the difficulties of side wall steel bar lap-joint, binding and water resisting operation space inadequacy of a construction site are solved.

Description

technical field [0001] The invention relates to the technical field of underground traffic engineering construction, in particular to an anti-fall conversion device for steel purlins. Background technique [0002] With the development of society, the pile support system is currently widely used in underground open-cut stations. However, when the traditional subway support pile support system is constructed, due to the constraints of structural safety and economic benefits, the steel support is usually farther away from the floor. The net distance is about 1m. The composition of the traditional pile support system is: steel support + steel purlin at the end + triangular bracket below the steel purlin. There are problems in the traditional pile support system: the net distance between the triangular support at the end of the steel support and the steel purlin below the structural plate is too small, which often leads to insufficient space for lapping, binding and waterproofin...
