Embodiment 1

[0064] The first embodiment is implemented for conventional steel structure buildings such as buildings / large public buildings.

[0065] Steel structure connection system for prefabricated buildings. In steel structure buildings, the steel structure system includes columns, beams and floor structures. The style of the columns usually includes steel pipes with a rectangular section, or an I-shaped section. steel, or other special structures. In this embodiment, a steel pipe with a rectangular section is taken as an example for illustration.

[0066] refer to Figure 1 to Figure 5 , in this embodiment, in the process of building the steel structure, the structure of the column is the same or similar, and according to the angle, method and layout of the supporting components on the column, the column is carried out according to the way of the A column and the B column respectively mark, but it should be noted that there is no essential difference in specifications and sizes bet...

Embodiment 2

[0106] In the first embodiment, four corbels are installed around each column, so that a grid-shaped crossbeam component system is formed in the steel structure system. In the actual steel structure, it can be simplified as required, for example, in each column Two corbels are formed to form a sun-shaped beam assembly system in the steel structure, refer to Figure 13 .

[0107] In this way, two corbels are formed on each column, which can reduce the number of corbels by half and the number of beams by half. This method also meets the following requirements:

[0108] 1. In the same row (X direction), the two adjacent columns A and B have one and only one pair of A corbels and B corbels arranged on the same line with each other, and a beam can be installed between the two corbels hoisting and installation requirements.

[0109] 2. In the same row, there is only one beam connection between two adjacent A columns and B columns;

[0110] 3. Two beams radially arranged in opposi...

Embodiment 3

[0114] Compared with Embodiment 1, this embodiment is different from the B corbel. Specifically, there is no baffle plate in the B corbel, that is to say, the beam and the B corbel are connected by lap joints, and after they are assembled in place, Welding is performed between the beam and the B corbel, so that one end of the beam is welded and fixed to the B corbel, and the other end is slidably connected to the rectangular sleeve in the A corbel. This structure is more convenient to implement than the first embodiment , this implementation structure can refer to Figure 14 with 15 .

Abstract

The invention discloses a steel structure assembling system for a fabricated building and a construction method to solve the problem that an existing fabricated system is bad in stress. The steel structure assembling system comprises stand columns, cross beams and brackets, the same sides of every two adjacent stand columns are only provided with one pair of brackets which are arranged linearly, and one cross beam is installed between the two brackets; every two adjacent stand columns are connected only through one cross beam, and the two ends of the cross beam are movably connected with the brackets on the corresponding stand columns; the periphery of every stand column is provided with at least two cross beams in an outward radial shape, the cross beams on the same stand column do not interfere with each other, and the radial directions of the cross beams on the every two adjacent stand columns are opposite; and the cross beams are located on the sides of the corresponding stand columns. According to the steel structure assembling system, the cross beams are overlapped on the periphery of the stand columns and are arranged in an overlaid radial shape, enough overlapping joint space and enough extensible and retractable space are achieved, and a more excellent anti-seismic property is achieved.

Description

technical field [0001] The invention relates to the technical field of prefabricated buildings, in particular to a steel structure building technology and connection structure. Background technique [0002] The prefabricated steel structure system refers to the housing units or components manufactured according to the unified and standard building part specifications. The processes that can be completed in the factory should be completed in the factory as much as possible. Ideally, the construction site only has the assembly process. The development and application of prefabricated steel structure systems are of great significance to the industrialization of structural engineering. The development of industrialized prefabricated steel structure systems is an urgent requirement for green buildings and building industrialization. [0003] As an important component of the prefabricated building system, steel structure is widely used in prefabricated buildings. According to the...
