Embodiment Construction

[0041] For a corridor installation project, the corridor has three floors, corresponding to the 10th, 9th, and 8th floors of the concrete building; the steel structure of the project is a suspended steel structure, and the corridor structure with functional functions from the 8th to the 10th floor passes through the 11th floor A system of steel trusses is suspended above the reinforced concrete structure. Therefore, the structure is dominated by 2 steel trusses, supplemented by 8-10 storey steel beams. Such stress characteristics require that the steel corridor should adopt a top-down construction sequence, that is, a "reverse construction method" construction sequence that is different from the conventional straight method.

[0042] The installation sequence is subdivided into 18 steps, which are:

[0043] Step 1: Installation of the first truss 1 (suspension) on the left side of the 11th floor ( figure 2 );

[0044] Step 2: Installation of the second truss 2 (suspension)...

Abstract

The invention relates to a building corridor construction technology, in particular to a down-top hoisting construction technology for a high-level multi-layer suspension steel structure. The down-top hoisting construction technology for the high-level multi-layer suspension steel structure comprises the following steps: I, hoisting a first truss on the inner side of the (n+1)th layer of a left-side building body; II hoisting a second truss on the inner side of the (n+1)th layer of a right-side building body; III, hoisting a main transverse beam between the pair of mounted trusses; IV, suspending the nth to the mth layers of first steel column frameworks on the main transverse beam; V, hoisting a first secondary transverse beam between the pair of trusses of the (n+1)th layer; VI, hoisting a second secondary transverse beam between spanning longitudinal beams of the nth layer, and hoisting a third secondary transverse beam between spanning longitudinal beams of an (n-1)th layer till hoisting of a secondary transverse beam between spanning longitudinal beams of the mth layer is finished; VII, hoisting a truss upper chord diagonal bracing and a longitudinal beam; VIII, hoisting (n+1)th to the mth layers of right-side outriggers.

Description

technical field [0001] The invention relates to the construction technology of building corridors, in particular to a construction technology for the reverse hoisting of high-altitude multi-layer suspended steel structures. Background technique [0002] At present, many buildings have a corridor structure. A corridor generally refers to a structure in which two or several high-rise buildings are connected to each other by an overhead connector. The corridor can be used as a connecting passage between two buildings, or as a Sightseeing and leisure purposes. The commonly used corridor construction method is to build two reinforced concrete structures (that is, two buildings), and then build scaffolding between the two reinforced concrete structures from bottom to top, and place the corresponding longitudinal beams, beams and other structures The parts are installed in place from bottom to top, and finally the scaffolding is removed. This method is technically mature, but the...
