Abstract

The utility model relates to a fabricated-type steel beam splicing joint which is characterized in that splicing plates are distributed in a staggering mode on an upper and lower wing edge of each splicing beam segment at each side of the fabricated-type steel beam splicing joint, and connection between the splicing plates and beams at two sides of the fabricated-type steel beam splicing joint are welded in a process factory in advance. During an on-site splicing installation process, the splicing plates which are firmly welded serve as ear plates to enable installation beam segments to be fast located. After location, connection between the splicing plates and the upper and lower wing edges on the other side beam, and splicing of two side webs are finished through bolts. Splicing joints in an installation scene are all spliced through the bolts. The fabricated-type steel beam splicing joint is reasonable in structure, clear in power transmitting, and fast in position during the on-site installation process. Moreover, welding is not required, construction efficiency is high, safety is good, installation efficiency is improved, and danger of fire disaster caused by welding is prevented. Simultaneously, at the construction site, the splicing joints are all assembled through the bolts, and the fabricated-type steel beam splicing joint brings convenience to the construction site where construction site conditions are severe and welding is inconvenient.

Description

A kind of assembling girder steel splicing node
Technical field
The utility model relates to a kind of construction steel structure slicing of beams mode, is specifically related to a kind of assembling splicing node.
Background technology
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, steel structure node affects great for structure power transmission, construction difficulty or ease, construction costs.
Wherein, slicing of beams node 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 is connected with web and connects with high-strength bolt; 3. the edge of a wing is connected full penetration weldering connection 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, higher to the requirement on machining accuracy of member and node, simultaneously, because the high-strength bolt unit price is more expensive, therefore cost is also high.In addition, when these three kinds traditional splicing nodes splice at the scene, owing to being that install in the high-altitude, for convenience in place also needs to weld in addition the ear plate in the top flange of beam, also to excise time-consuming taking a lot of work after node construction is complete.
The utility model content
The utility model is for existing installation in position need borrow auxiliary part in the existing steel structure girder splicing, the field operation engineering quantity is large, cycle is long, and installation quality is difficult to the deficiencies such as guarantee, and a kind of on-the-spot welding, flexible, the safe and reliable quick-assembling node of splicing are provided.
The technical solution of the utility model 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, first 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 rear beam section in place is connected with the top flange of this Duan Liang by weld seam and connects, 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 first;
Preferably, the overhanging side of top flange scab of rear 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 first;
Preferably, the bottom flange of rear beam section in place is held bolt hole successfully in processing factory;
Preferably, the scab of the upper bottom flange of the splicing node of girder steel 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 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.
