Node component of steel structure and assembling method thereof

Abstract

The invention relates to a node component of a steel structure, comprising profile steel, round steel and a steel plate connecting piece fixed on the outer wall of the profile steel; one side of the steel plate connecting piece is connected with a positioning plate; the steel plate connecting piece is provided with a bolt hole; the positioning plate is provided with a positioning hole corresponding to the bolt hole; the bolt hole and the positioning hole are penetrated with bolts; one end of the round steel is a connecting part which is arranged between the steel plate connecting piece and the positioning plate and is sheathed on the bolt; and the steel plate connecting piece, the connecting part of the round steel and the positioning plate are fixed into one body by matching and connecting of the bolts and nuts. The invention also relates to an assembling method of the steel structure node component. The invention has the advantages of high connecting strength, convenient disassembling, easy processing and wide application range.

Description

technical field [0001] The invention relates to an engineering structure assembly, in particular to a steel structure node assembly for connecting section steel and round steel and an assembly method thereof. Background technique [0002] Steel structures are widely used in the field of structural design. At present in our country, the design of steel structure has been paid more and more attention and developed. In steel structure design, steel structure node components, that is, the connection structure between section steel and steel pipe or angle steel or round steel, is one of the important links in steel structure design. [0003] Most of the existing steel structure node components are the connection structure of section steel and steel pipe, or the connection structure of section steel and angle steel. figure 1 It is a schematic diagram of the joint connection structure of the existing section steel and steel pipe, such as figure 1 As shown, the connecting end of ...

AI Technical Summary

Problems solved by technology

The shortcoming of above-mentioned structure is: 1, when the outer wall of the steel pipe connection end of bevel shape and shaped steel 21 is welded, the professional skill requirement of electric welder is higher, when producing in large quantities, because the professional technical level of each electric welder is different. Different, it is difficult to guarantee the welding quality, and it is not suitable for mass production

2. Due to the connection and fixation by welding, although it can meet the strength requirements of engineering design, the section steel and steel pipe cannot be disassembled after welding, which will cause the overall workpiece to be too large and bring great inconvenience to transportation.

In order to avoid the inconvenience of transportation, the operation method of assembly and welding on site is usually adopted, but this requires that the site must meet the specified welding conditions, which increases the difficulty of assembly and increases the processing cost. The influence of external factors is relatively large, and the working environment is often difficult to guarantee, thus affecting the welding quality and resulting in a low pass rate of products

3. The scope of application is small, and it is not suitable for the connection between section steel and round steel. The reason is that the welding area of ​​round steel is small, and the round steel is solid steel. Larger, prone to cracks or even breakage at the weld

Although the above-mentioned structure overcomes the defects of non-detachable and difficult construction work in the prior art through the detachable bolt connection structure, it also has some defects: this structure is not suitable for the connection between the round steel and the section steel, due to the cross-section of the round steel The cross-section is small and solid material, so it is not suitable to open a through hole on the round steel, so the connection with the steel plate connector 23 cannot be realized by means of bolt connection

The disadvantages of the above structure are: 1. The structure is complex and the production cost is high; 2. The round steel pipe can only be laid between the steel beam and another steel beam, which cannot meet the needs of the engineering structure; 3. The bolts need to pass through the clamped Supported round steel pipe, not suitable for fixed connection between round steel and profiles
