Embodiment Construction

[0065] The present invention is described in detail below in conjunction with accompanying drawing:

[0066] as attached figure 1 As shown, the splicing position of the new fabricated beam slab of the present invention is set in the middle of the main girder, where the shear force and bending moment are relatively small. From the perspective of structural mechanics, the setting of the splicing position is very reasonable.

[0067] as attached figure 2 And attached Figure 4 As shown, in the novel multi-high-rise assembled steel structure frame-central support system described in the present invention, the involved beams are equipped with hollow-type angle steel beams with channel steel webs, including angle steel upper and lower chords 1, channel steel webs 2 , the channel steel web is perpendicular to the chord, and the upper and lower ends of the web are welded to the angle steel legs of the upper and lower chords; all angle steel beams are connected at regular intervals ...

Abstract

The invention provides a multi-high-layer assembly type steel structure frame-center supporting system, and belongs to the technical field of structural engineering. The system comprises assembly type beam-slabs, assembly type upright columns and profile steel inclined supports. Each assembly type beam-slab comprises a floor, a column joint and a hollow steel beam of a matched profile steel web member. The hollow steel beams are connected with the column joints, the floors are supported on the hollow steel beams, and each assembly type upright column is composed of a box-shaped column and a flange plate. During construction, the assembly beam-slabs and the assembly type upright columns are connected to form a frame structure, the profile steel inclined supports are arranged on the basis of the steel frame, and lateral stiffness of the structure is improved. All elements of the system are precast in factories and are rapidly assembled to form the structural system through bolts on construction sites. Concrete pouring and welding work are not needed, the defects that a traditional building is long in construction period, severe in material waste, severe in pollution during the construction process and the like are reduced, and factory integral production of the building can be achieved.

Description

technical field [0001] The invention relates to a multi-high-rise assembled steel structure frame-central support system, which belongs to the technical field of structural engineering. Background technique [0002] According to statistics from the China Iron and Steel Association, my country’s steel output exceeded 700 million tons in 2011, ranking first in the world’s steel output for 16 consecutive years. Although China is the country with the largest construction scale and steel output in the world, housing (including residential) Structural development has lagged behind. At present, in developed countries, such as the United States and European countries, the steel structure construction area accounts for more than 50% of the total construction area, and Japan accounts for 80%, while our country accounts for less than 4%. [0003] Moreover, traditional buildings have disadvantages such as long construction period, serious waste of materials, and heavy pollution during c...
