Portable temporary bridge for connecting tower crane with building

Abstract

The invention discloses a portable temporary bridge for connecting a tower crane and a building. The portable temporary bridge comprises a structural bulk stereogram of a supporting device. A temporary bridge main keel, a temporary bridge cross rod, a front limiting hook, a rear limiter and a protective barrier are all of steel structures formed by machining plastic steel and steel plates, the position over the temporary bridge main keel is formed by seamlessly connecting two reinforcing meshes with the size of 2,000 mm * 1,000 mm, and the front limiting hook is arranged in front of the temporary bridge main keel. and is welded to the middle of the front section of the main keel together with the temporary bridge main keel, the rear limiter is arranged behind the temporary bridge main keel, and is welded to the middle lower portion of the rear section of the main keel together with the temporary bridge main keel, and the two portions above the temporary bridge main keel are both provided with protective barriers, are also steel structure components and comprise transverse rods and vertical rods. The invention further discloses a construction process of the temporary bridge main keel and the protective barrier in the supporting device, a welding machining process and matters needing attention among all steel structures of the supporting device, rust-proof treatment after weldingis completed, and material compositions of steel structural members and the steel bar meshes.

Description

technical field [0001] The invention relates to the technical field of construction, in particular to a bridge connecting a portable tower crane and a building. Background technique [0002] In the field of modern construction engineering, the safety of tower cranes has always been a key point in construction safety. Because of the high height of the tower cranes on the construction site, there has been no standardized passing device between the building structure and the tower crane. The temporary aisles that are overlapped are not standardized or even unqualified, and it is easy to cause engineering quality accidents at this time. [0003] Not only from the perspective of the safety and border of the tower crane's passage up and down or between the main body, but also from the safety of the tower crane driver's daily passage, a safe temporary aisle support device should be established between the tower crane and the building. Every construction site The number of tower cr...
