Abstract

The utility model relates to a column beam connection node structure of the steel construction. An upper through diaphragm plate and a lower through diaphragm plate are arranged on a square steel pipe column in the fusion penetration welding mode. The middle of the square steel pipe column is provided with a sternum connecting plate. The two blade edges of an H-shaped girder steel are welded in the fusion penetration mode on the upper diaphragm plate and the lower diaphragm plate. The sternum is connected with the sternum connecting board through a high strength bolt. The column beam connected by the connection node structure has the advantages of strong integrality, high reliability, few material consumption and convenient processing and producing and can be extensively applied to the connection of the square steel pipe column and the H-shaped girder steel in the steel construction.

Description

Connect the board-like square column beam connecting node of tabula structure

Technical field

The utility model belongs to the building unit technical field, is specifically related to a kind of steel building center pillar beam connecting node structure.

Background technology

Along with a large amount of rises of steel building in China, the attention that many high-rise steel structure are built with its intensity height, from heavy and light, series of advantages such as anti-seismic performance is good, speed of application is fast, ground cost saving, area occupied is little, industrialization degree is high, good looking appearance, environmental protection more and more are subjected to various places government, large-scale steel structure company and real estate developer.And in the construction work of many high-rise steel structure, the connection of post beam is an important link.Whether post beam type of attachment is proper, to guaranteeing the globality and the reliability of many high-rise steel structure building, to making the quality and the progress of installing, there is direct influence whole construction period and cost.In engineering in the past, the H section steel beam is connected with square, rectangle steel tubing string, generally adopt traditional internal partition pattern, and there is following shortcoming in traditional beam-column connection:

1, the top flange of H girder steel wallboard direct and the rectangle steel tubing string carries out field Welding, because the pulling force of H section steel beam top flange is bigger, the field Welding influence makes the material plasticity of this position steel pipe column wallboard reduce again, so thicker post jamb plate is easy to produce lamellar tearing.Connection reliability is greatly affected.

2, traditional internal partition bean column node can not use in cold roll forming square tube node, brings tremendous influence to engineering cost.

3, traditional bean column node, in connect diaphragm and need could be connected with the wallboard of rectangle steel tubing string by electroslag welding with consumable nozzle, processing equipment is had relatively high expectations, the PROCESS FOR TREATMENT trouble, weldquality also is difficult to guarantee.

Summary of the invention

It is convenient that the purpose of this utility model is to propose a kind of processing and fabricating, the post beam connecting node structure of the steel building that connection reliability is good.

The post beam connecting node structure of the steel building that the utility model proposes is to be connected with the H section steel beam at square (comprising square and rectangle) steel pipe column.Its structure as shown in Figure 1-Figure 3.Wherein, locate to be provided with upper and lower two at square bar tubing string 1 corresponding to two edges of a wing of H section steel beam 2 and connect

diaphragms

3 and 4, diaphragm is connected by full penetration weld 6 with the square bar tubing string; Between the upper and

lower tabula

3,4 web junction plate 5 is set vertically, this web junction plate 5 connects with square bar tubing string one face down bonding; Two edges of a wing of H section steel beam 2 and upper and

lower diaphragm

3,4 are connected by full penetration weld 8, and the middle pectoral plate of H section steel beam 2 is connected by high-strength bolt 7 with web junction plate 5.

The perforation tabula plate tower beam connecting node structure of the utility model design, the globality of connection is strong, the reliability height, material consumption is economized, and processing and fabricating is convenient, and the post beam that can be widely used in steel building on the middle and senior level connects.

Description of drawings

Fig. 1 is this post beam connecting node plane diagram.

Fig. 2 is this post beam connecting node facade diagram.

Fig. 3 is this post beam connecting node three-dimensional icon.

Number in the figure: 1 is the square bar tubing string, and 2 is H shape girder steel, and 3 for the upper end connects diaphragm, and 4 for the lower end connects diaphragm, and 5 is the web junction plate, and 6 is full penetration weld, and 7 is high-strength bolt, and 8 is full penetration weld.

The specific embodiment

Certain engineering is steel frame-steel reinforced concrete tube structure system, and architectural design service life is 50 years, and safety classes of structure is a secondary, and building aseismicity is set up defences and is categorized as Class C, and seismic fortification intensity is 8 degree; The above agent structure in ground is a steel work, and frame column adopts square steel pipe, typical floor column section 500 * 500 * 18 * 18, and material is Q345B.Vierendeel girder adopts H type cross section, typical floor beam section 600 * 195 * 10 * 16, and material is Q345B.Frame beam column connects this perforation of employing diaphragm connected node structural shape, web junction plate 5 on the web of H section steel beam 2 and the square tube post 1 adopts M24 high-strength bolts 7 to be connected, the thickness of square tube post upper and

lower end diaphragm

3,4 is 20mm, carries out full penetration weld with the upper and lower edge of a wing of H section steel beam 2 respectively and is connected.Concrete steps are as follows:

In factory, first square shaped, rectangle steel tubing string carry out setting-out, cutting section, welding ends groove, then with upper and lower end connect

diaphragm

3 and 4 and web junction plate 5 assemble welding, form whole post member.The H section steel beam is carried out setting-out, welding assembly, drilling, form whole beam.When carrying out the beam column splicing at the construction field (site), earlier that beam column is in place, correction, then web is connected 5 usefulness high-strength bolts 7 with web on the post and connects, respectively field Welding is carried out with the perforation of the upper and lower end on

post diaphragm

3 and 4 in the upper and lower edge of a wing of H section steel beam at last.
