Abstract

The invention relates to an assembled splicing node of constructional steel structural beams. The splicing node of the beams is characterized in that splicing plates are intersectionally arranged on upper and lower flanges at splicing beam sections on the two sides, and the splicing plates on the two sides of are connected with the beams by welding in a processing plant in advance. The securely welded splicing plates on the two sides serve as lug plates to allow the mounting beam sections to be in place quickly during on-site splicing and assembly. After the beam sections are in place, the splicing plates are connected with upper and lower flanges of the beam on the other side, and web plates on the two sides are spliced. The splicing node is spliced by the bolts at a mounting site. The splicing node is reasonable in structure, free from welding, high in construction efficiency and good in safety, transmits a force clearly, and is in place quickly during on-site mounting, the mounting efficiency can be improved, and the fire risk caused by the welding can be avoided. In addition, the node is assembled by the bolts at the construction site, and great convenience is brought to the site where the welding is inconvenient due to severe construction site conditions.

Description

A kind of assembling girder steel splicing node
Technical field
The present invention relates to a kind of connecting method of construction steel structure beam, be specifically related to a kind of assembling splicing node.
Background technology
Steel work has the intensity height, from heavy and light, 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, be 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 Chinese economic development and comprehensive strength, steel building will develop rapidly.And in steel work, steel structure node influences great for structure power transmission, construction difficulty or ease, construction costs.
Wherein, the splicing node of beam splicing form traditionally mainly contains three kinds: 1. going up the bottom flange is that full penetration weld connects, and web connects with high-strength bolt; 2. going up the bottom flange all is connected with high-strength bolt with web; 3. the edge of a wing and web are the full penetration weldering and are connected.For first kind and the third connected mode, the bottom flange is that full penetration connects on the beam, needs in the construction welding again is installed earlier, and construction speed is longer, because work high above the ground, weldquality is difficult to guarantee.For second kind of connecting method, the full bolt connecting mode that the edge of a wing and web all are connected with high-strength bolt, to the requirement on machining accuracy of member and node than higher, simultaneously because the high-strength bolt unit price is more expensive, so cost is also high.In addition, when these three kinds traditional splicing nodes splice at the scene, owing to be that install in the high-altitude, for convenience in place also needs to weld the ear plate in addition in the top flange of beam, after finishing, also to excise node construction time-consuming taking a lot of work.
Summary of the invention
The present invention is directed in the existing steel structure girder splicing exists installation in position need borrow auxiliary part, the field operation engineering quantity is big, cycle is long, and installation quality is difficult to deficiencies such as guarantee, and a kind of on-the-spot do not have welding, flexible, the safe and reliable quick-assembling node of splicing are provided.
Technical scheme of the present invention is: a kind of assembling splicing node of girder steel, the girder steel section that comprises both sides, scab and supporting bolt, the upper and lower edge of a wing scab interlaced arrangement of beam is in the outside, the upper and lower edge of a wing of the beam section of both sides, and in processing factory, finish welding with the beam section in advance, and splicing at the scene in the installation process, upper and lower edge of a wing scab serves as plate in place, after member was in place, the upper and lower edge of a wing of beam and web were all realized the splicing of node with bolt;
Preferably, earlier the bottom flange scab of beam section in place is connected with the bottom flange of this Duan Liang by the weld seam connection, and has welded in processing factory and to have finished;
Preferably, the top flange scab of back beam section in place is connected with the top flange of this Duan Liang by weld seam connection, and has welded in processing factory and to have finished;
Preferably, the web of two sections girder steels is held bolt hole successfully in processing factory;
Preferably, the overhanging side of bottom flange scab of beam section in place is held bolt hole successfully in processing factory earlier;
Preferably, the overhanging side of top flange scab of back beam section in place is held bolt hole successfully in processing factory;
Preferably, the top flange of beam section in place is held bolt hole successfully in processing factory earlier;
Preferably, the bottom flange of back beam section in place is held bolt hole successfully in processing factory;
Preferably, the scab of the last bottom flange of the splicing node of girder steel is made usefulness in place in splicing is installed;
The invention has the beneficial effects as follows: the present invention is rational in infrastructure, power transmission is clear and definite, do not have welding, efficiency of construction height in the field-mounted process, and safety is good.This invention 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 in the installation process at the scene, convenient in place, need not weld, both improve installation effectiveness, avoid welding to bring the risk that causes fire again; Welding has been avoided in this invention at the construction field (site), and adopts the bolt Fast Installation, and the building site that this is inconvenient to weld for the job site inclement condition brings great convenience; Simultaneously, owing to the convenience of node concatenation, will advance the standardized process of steel structure system.
