Abstract

The utility model relates to an assembly type rigid node of a steel-structure beam column of a building, wherein splice plates are alternatively arranged on the upper and lower flanges of cantilever beams and frame beams. Meanwhile, splice plates on the two sides of the rigid node are connected with beams through weld joints in steel machining plants in advance. During the on-site installation process of the rigid node, splice plates firmly welded with the two sides of the rigid node are served as ear plates, so that installation beam sections can be quickly positioned. After the beam sections are positioned, the splice plates are connected with the upper and lower flanges of beams on the other side of the rigid node, and web plates through bolts, so as to complete the installation of the rigid node of the beam column. The on-site splicing of the rigid node of the beam column is realized completely through bolts. The rigid node of the beam column has the advantages of reasonable structure, definite force transmission, rapid on-site positioning during the installation process, no welding operation, high construction efficiency and good safety. Due to the adoption of the rigid node of the beam column, the installation efficiency is improved and the risk of fire hazards caused by welding operation is avoided. Meanwhile, since the on-site splicing of the rigid node is realized completely through bolts, thereby greatly facilitating construction sites, where field conditions are too poor to realize the welding operation.

Steel work have intensity high, from heavy and light, the series of advantages such as anti-seismic performance is good, speed of application is fast, ground cost saving, floor space is little, industrialization degree is high, good looking appearance.Compare the characteristics with environmental protection and reusable edible with concrete structure, the environmental type product of generally acknowledging, the policy that meets sustainable development, developed country extensively adopts steel work in building construction, in the U.S., Japan, the steel work steel using amount has accounted for more than 30% of output of steel, and along with the enhancing of China's expanding economy and comprehensive strength, steel building will develop rapidly.And in steel work, the bean column node of steel work is great for impacts such as structure power transmission, construction costs, difficulty of construction.

The beam column rigid joint has three kinds of types of attachment traditionally: 1. going up the bottom flange is that full penetration weld connects, and web connects with high-strength bolt, i.e. bolt weldering mixes and connects; 2. go up the bottom flange and be connected with web with the high-strength bolt connection, namely full bolt connects; 3. the edge of a wing is connected weld seam connection, i.e. all-weld joint with web.For the first and the third connected mode, the bottom flange is that full penetration connects on the beam, needs to install first again welding in the construction, and construction speed is longer, because work high above the ground, weldquality is difficult to guarantee.For the second connecting method, be connected with web with the full bolt connecting mode of high-strength bolt connection in the edge of a wing, and the requirement on machining accuracy of member and node is higher, because the high-strength bolt unit price is more expensive, therefore cost is also high.In addition, when these three kinds traditional beam column rigid joints splice at the scene, owing to be that install in the high-altitude, for convenience in place also needs also will excise time-consuming taking a lot of work after node construction is complete at the additional welding in the top flange of beam ear plate.

The utility model content

The utility model needs to borrow auxiliary part in place in the peace termination process for existing beam column of steel structure rigid joint, the field operation engineering quantity is large, cycle is long, installation quality is difficult for the problems such as guarantee, provides a kind of scene to need not to weld, splice flexible, safe and reliable quick-assembling rigid joint mode.

The technical solution of the utility model is: a kind of assembled beam-column rigid joint, comprise steel column, cantilever beam section with the steel column welding, steel-frame beam, scab and supporting bolt, wherein, the top flange scab of beam is arranged the upside of Vierendeel girder section, and in processing factory, finish welding with the top flange in advance, the bottom flange scab of beam is arranged the downside of cantilever beam section, and in processing factory, finish welding with the bottom flange in advance, at the scene in the installation process, beam upper, the bottom flange scab serves as plate effect in place, after member is in place, beam upper, bottom flange and web all connect with bolt, realize being rigidly connected of bean column node;

Preferably, the upper bottom flange of semi girder is connected by butt weld with steel column, and web is connected by fillet weld with steel column, and being welded to connect in steel work processing factory between them finished;

Preferably, the bottom flange of the cantilever beam section that is connected with steel column is connected with scab by weld seam and connects, and has welded in steel work processing factory and finished;

Preferably, the top flange of steel-frame beam was connected weld seam with scab and was connected, and had welded in steel work processing factory and to have finished;

The web of the semi girder that preferably, is connected with steel column is held bolt hole successfully in steel work processing factory;

Preferably, the web of steel-frame beam is held bolt hole successfully in processing factory;

Preferably, the top flange scab sponson of steel-frame beam is held bolt hole successfully in steel work processing factory;

Preferably, the semi girder bottom flange scab sponson that is connected with steel column is held bolt hole successfully in steel work processing factory;

Bolt hole is held in the outside of the top flange of the semi girder that preferably, is connected with steel column successfully in processing factory;

Preferably, bolt hole is held in the outside of the bottom flange of steel-frame beam successfully in processing factory;

Preferably, the scab of upper bottom flange is used as in place in splicing is installed.

The beneficial effects of the utility model are: the utility model is rational in infrastructure, power transmission is clear and definite, welding in the field-mounted process, efficiency of construction are high, and safety is good.This utility model is by the reasonable Arrangement of bottom flange scab on the beam, interaction arrangement is in two sides splicing beam section respectively, and in processing factory, finish with the welding of beam section in advance, splice at the scene in the installation process, convenient in place, need not weld, both improve installation effectiveness, avoid again welding to bring the risk that causes fire; This utility model has been avoided welding at the construction field (site), and adopts the bolt Fast Installation, and great convenience is brought in the building site that this is inconvenient to weld for the job site inclement condition; Simultaneously, because the convenience of node concatenation will advance the standardized process of steel structure system.
