Problems solved by technology

That is to say, the connection is completed by local reinforcement. Although the installation and disassembly are convenient and the connection strength of the overall structure is high, the structure is very complicated, and the production cost is several times that of the above two, and it is still necessary to drill holes in the beams and columns to form installation points

Embodiment 1

[0073] Taking the connection method of steel pipe columns and steel beams as an example to illustrate one of the implementation methods, for example, in figure 1 , a light steel structure system composed of beams and columns.

[0074] The following is attached with the manual figure 1 to the attached Figure 13 The serial, partial or global structural views in the present invention explain in detail the essence and implementation process of the present invention, and the applicant describes in detail as much as possible, but still does not rule out whether there is a detailed explanation. For this embodiment For the inappropriate and unsatisfactory wording in the document, technical personnel can understand it according to the technical common sense and knowledge in this field.

[0075] The orientation words such as up and down in this embodiment refer to the gravity coordinate system. In this embodiment, the near end and the far end are described with the reference point a...

Embodiment 2

[0097] refer to Figure 14 , in this embodiment, the position and state of the slot 113 are not perpendicular to the length direction of the steel pipe column, and are suitable for special installation positions. For example, this structure is suitable for the installation of beams with a certain slope, such as various roofs and balconies with slopes. That is to say, in the sheet metal fabrication stage of the steel strip 110 , it is enough to design the slot 113 to form a certain angle with the steel pipe column and have a certain slope structure. During the installation process, self-tapping screws can be used for auxiliary fixing to complete the installation of beams and columns.

Embodiment 3

[0099] refer to Figure 15 , for a multi-storey steel structure building, the steel pipe column 100 is pre-set in the form of matryoshka, so that the specific application of the nesting doll technology in the steel structure, specifically, the steel pipe column 100 is processed into different size series, for example In this embodiment, the steel pipe column includes an inner and outer structure, the height of the inner steel pipe column is greater than the height of the outer steel pipe column, and the inner steel pipe column is nested in the outer steel pipe column. Steel pipe column 100, nested, wherein the inner diameter of the outer steel pipe column is equivalent to the outer diameter of the inner steel pipe column, and no patch is provided at the corresponding slot position on the outer steel pipe column, and the inner steel pipe column acts as a patch role, with good compressive strength. Usually, the outer steel pipe column is used to support the floor load of the lo...

Abstract

The invention discloses a fabricated building steel structure system and a construction method thereof. The fabricated building steel structure system comprises a three-dimensional frame system constituted by steel pipe columns and steel beams, the steel pipe columns are a polygon prism formed by a plurality of steel belts which are welded, inserting parts are arranged on the steel pipe columns, the ends of the steel beams and the inserting parts are connected in an inserted mode, and emulsified asphalt is arranged at inserting points according to needs. According to a technology, fully-coatedstructures are formed between the two ends of the steel beams and the inserting parts, the effective area of coating is large, the bonding strength is higher, and thus shock resistance and the firm degree of joints are much larger than those of a traditional connecting technology; and through using of the emulsified asphalt, cold and heat broken bridges can be formed at the joints, and building energy conservation is facilitated.

Description

technical field [0001] The invention relates to the technical field of prefabricated building construction, in particular to a prefabricated light steel structure installation node and a construction and installation method. Background technique [0002] At present, light steel structures are widely used in office buildings, villas, warehouses, stadiums, entertainment, tourism buildings, low-rise and multi-storey residential buildings and other fields. [0003] For the node connection technology in light steel buildings, it has a wide range of application scenarios, such as: [0004] CN102561510A discloses a light steel technology, which includes two relatively parallel sheet columns, a middle support connecting plate for the sheet column connected between the two sheet columns by self-tapping screws, and a connecting plate connected by self-tapping screws. The foundation connector at the bottom of the sheet column, and the roof truss connector connected to the top of the s...
