Problems solved by technology
The main reason for the collapse: the corridor has two floors, the upper floor is suspended on the roof truss by suspenders, and the suspenders of the lower floor are fixed on the steel beams of the upper floor, but the connecting nodes are not checked and strengthened, which eventually leads to damage at the nodes, and even Corridor collapse

Embodiment Construction
[0020] The patent of the present invention will be further described below with reference to the accompanying drawings.
[0021] like Figure 1-Figure 5 As shown, the present invention includes a landing structure 1, a conversion truss 2, several suspension floors 3, steel tie rods 4, a suspension node A of the suspension floor and a connection node B of the lower chord of the truss. The transfer truss 2 is reliably connected to the floor structure 1 to form the main bearing system. Each suspended floor 3 is connected to the transfer truss 2 through an independent steel tie rod 4, and the suspension floor 3 is horizontally connected to the floor structure 1. The suspension floor 3 is directly connected under the conversion truss 2 through an independent steel tie rod 4, and is not connected to the suspension floor 3 above it. Node A includes a steel column sleeve 5, a floor steel beam 6, an outer ring plate 7, a steel tie rod 8 for hanging the floor, a steel tie rod 9 for han...

The invention relates to a weak correlation suspension structure system of each floor and a construction method thereof. The system comprises a floor structure, a roof conversion truss, a plurality of suspension floors and steel pull rods, the roof transfer truss is reliably connected with the floor structure to form a main bearing system, the suspension floors are connected with the roof transfer truss through independent steel pull rods, and steel beams and floor slabs of the suspension floors are horizontally connected with the floor structure. The steel pull rod only bears vertical load, and wind load and horizontal earthquake action are directly transmitted by hanging floor systems of all layers and connecting with a floor structure. The stress of the roof transfer truss is related to the weight of each suspension floor, but the suspension floors are not directly connected, and the mutual influence of the stress and deformation of the suspension floors is weak. By means of special design of butt joint node construction, suspended floor plane arrangement and construction sequence, weak correlation concepts of all floors are guaranteed to be achieved. The structural system is clear in force transmission, simple in construction and good in economical efficiency, and the construction quality is easy to guarantee.
Description
technical field [0001] The invention relates to a weak correlation suspension structure system of each layer and a construction method thereof. It is especially suitable for projects where local vertical components of the main structure cannot be grounded due to architectural modeling requirements, and conversion trusses are conditionally installed on the top. The invention provides solutions in terms of structural system, node structure, suspended floor structure arrangement, construction scheme and the like. Background technique [0002] In the traditional structural form, the vertical members are mostly compression-bending members, and the material of the vertical members is steel or concrete or steel-concrete combination; the vertical members within the scope of the suspended body in the suspension structure system are tension-bend or axial-tension members, and the vertical members The material can be steel or steel cables. Compared with compression-bending and tension...
