Abstract

The invention provides a construction control method of a corridor consisting of large-span trusses different in length. The construction control method comprises the following steps that the lower chord node at the rigid connection end of each truss is configured to serve as a temporary connection node; the upper chord nodes of the trusses are configured to serve as hinge nodes; temporary opposite-pull diagonal bracings serving as temporary supports are arranged at the midspans between the upper trusses and the lower trusses; the temporary supports are dismounted after all construction nodes of a corridor steel structure are completed; concrete floor slab casting is performed after the temporary supports are dismounted; the temporary connection nodes are replaced by permanent connection nodes. By means of the construction control method of the corridor consisting of the large-span trusses different in length, the construction control problem produced under the situation that a large-span corridor truss structure is different in truss length and more greatly influences a support seat structure is solved.

Description

technical field [0001] The invention relates to the field of building construction, and in particular to a method for controlling the construction of a corridor composed of long-span trusses with different lengths. Background technique [0002] Corridor structures are mostly used in large-scale commercial plazas to connect various main structures, and most of them are steel truss structures. At present, temporary support and scattered hoisting construction techniques are mostly used, but the conventional hoisting and unloading techniques are implemented with different lengths. For large-span trusses, during the unloading process, there will be differences in settlement due to the different deflections of the two trusses, which will affect the level of the floor structure beams and have a greater impact on subsequent construction, and the construction will be carried out directly according to the drawing if one end is rigidly connected and the other end is hinged It will also...
