Large-span corridor between unequal-height high-rise buildings

Abstract

The invention relates to the field of corridors, in particular to a large-span corridor between unequal-height high-rise buildings, which comprises a bottom plate layer, a top plate layer, chord pipes, web members and preassembled pipes, elastic plates for the chord pipes to abut against are arranged on the preassembled pipes, and avoiding mechanisms for avoiding the elastic plates when the chord pipes on the top plate layer approach are arranged on the four lower preassembled pipes. The elastic plate can be reset again after successful avoidance; a connecting rod and a first elastic piece are arranged in the preassembling pipe; a positioning groove is formed in the upper surface of the connecting rod, a through hole communicated with the elastic plate and the positioning groove is formed in the preassembling pipe, a positioning rod which penetrates through the through hole and is inserted into the positioning groove is arranged on the elastic plate, and the positioning rod is used for positioning the connecting rod in the preassembling pipe; and the positioning rod is separated from the positioning groove. According to the scheme, the step that workers frequently observe butt joint of the preassembled pipe and the chord pipe is omitted, and the workload and potential safety hazards of the workers are reduced.

Description

technical field [0001] The application relates to the field of corridors, in particular to a long-span corridor between high-rise buildings of different heights. Background technique [0002] In order to meet the architectural functional requirements between the two high-rise towers, the two towers are often connected by corridors to form a conjoined structure. [0003] Such as Figure 4 , shown in the figure is a kind of corridor, including the bottom layer 1, the top layer 2, the chords 3 arranged on both sides of the bottom layer 1 and the top layer 2, and fixedly connected between the two chords 3 on the same side The webs 4 between them, and the pre-installed pipes 5 pre-installed on the tower to connect the chords 3. After the corridor is assembled, the workers install and debug the hydraulic lifting system, and lift the corridor through the hydraulic lifting system. When the end of the string tube 3 is aligned with the end of the corresponding pre-installed tube 5, t...

AI Technical Summary

Problems solved by technology

[0004] When the heights of the two towers are not the same, the settlement of the two towers will be different, and the pre-installed pipes that should be aligned on the two towers will also have a height difference of a few centimeters. The workers adjust the two ends of the corridor through the hydraulic lifting system. Raising the height can solve the problem of height difference, but during the height adjustment of the corridor, workers need to frequently observe the connection between the string pipe and the pre-installed pipe, which greatly increases the workload of the workers and the safety hazard when working at heights
