Abstract

The utility model belongs to the technical field of civil engineering and particularly relates to a bolting-welding mixed joint for on-site butting of steel girders and flanges, which consists of frame beams, friction type high-strength bolts, clamping plates, flange plates, tension-resistant high-strength bolts and reinforcing plates, the frame beams include an end girder section and a middle girder section which are butted to each other, the clamping plates are arranged on two sides of a web of the end girder section and a web of the middle girder section at the butted joint of the end girder section with the middle girder section, the clamping plates and the webs are connected through the friction type high-strength bolts, the flange plates are arranged at the joint of the lower flange of the end girder section with the lower flange of the middle girder section and are connected through the tension-resistant high-strength bolts, and the reinforcing plates are arranged on two sides of the flange plates to form rigid flanges. When the frame beams are mounted on a construction site, the frame beams are connected through the double-sided clamping plates, and at the beginning, the friction type high-strength bolts are screwed as common bolts and pretension force is exerted to the bolts after the upper flange and the lower flange are connected. The bolting-welding mixed joint for the on-site butting of the steel girders and the flanges has the advantages of safety, reliability, definiteness in transmission, simplicity in structure, convenience in construction and the like.

Description

The on-the-spot edge of a wing butt joint of girder steel bolt-weldering mixes connected node
Technical field
This is suitable for the novel technical field of civil engineering that belongs to, and is specifically related to the on-the-spot edge of a wing butt joint of a kind of girder steel bolt-weldering and mixes connected node, can extensive use in steel wood combination construction and light section steel structure civilian construction.
Background technology
At present in light section steel structure and steel wood combination construction, Steel Frame Column and beam-ends connected node, conventional way is all to adopt high strength friction-type bolt to be connected on the edge of a wing of the H of splice point place section beam with web; Or the butt weld connection of complete penetration is adopted, the connection of web employing high-strength bolt friction-type in the edge of a wing; Or the edge of a wing all adopts the butt weld of complete penetration to be connected with web.Though the connected mode stress performance of above routine is good, extensive use in steel framed structure, but still be difficult to satisfy the requirement of suitability for industrialized production assembled steel wood or lightweight steel construction rapid construction.The utility model makes every effort to adopt rational detail structure, is convenient to building site assembling construction, to reduce construction cost and reduction of erection time.
Summary of the invention
The utility model mixes dwelling house (or office building) to five to six layers of steel wood, provides the on-the-spot edge of a wing butt joint of a kind of girder steel bolt-weldering to mix connected node.This connected node power transmission mechanism is clear and definite, and it is quick and convenient to construct, and has guaranteed the strength and stiffness of member.
The utility model proposes the on-the-spot edge of a wing butt joint of a kind of girder steel bolt-weldering and mixes connected node; Form by Vierendeel girder 1, friction type high strength bolt 4, clamping plate 5, flanged plate 6, tension high-strength bolt 7 and stiffener 8; Wherein: Vierendeel girder 1 comprises end carriage section 2 and middle girder section 3, end carriage section 2 and 3 butt joints of middle girder section, said joint; The both sides that are positioned at end carriage section 2 webs and middle girder section 3 webs are provided with clamping plate 5, are connected through friction type high strength bolt 4 between these clamping plate 5 and the said web; End carriage section 2 bottom flanges and junction, middle girder section 3 bottom flange are provided with flanged plate 6, and said flanged plate 6 connects through tension high-strength bolt 7, and flanged plate 6 both sides are provided with stiffener 8, form rigid flange; End carriage section 2 top flanges and the welding of junction, middle girder section 3 top flange, weld is provided with run-on tab.
In the utility model, said end carriage section 2 is positioned at apart from one times of deck-molding place of beam-ends with middle girder section 3 joints.
In the utility model, carry out the Vierendeel girder building site when installing, connect with two-sided clamping plate 5, friction type high strength bolt 4 is generally tightened by plain bolt during beginning, after the connection of the upper and lower edge of a wing finishes, again friction type high strength bolt 4 is applied pretension.
The utility model has the advantages that:
(1) shearing resistance is accomplished by high-strength bolt and clamping plate in the Vierendeel girder splicing connected node.In the bending Design, consider that beam end not only can produce positive bending moment, the situation that also has hogging moment to produce.Therefore, the bottom flange is designed to increase the strength bolts ways of connecting with flange, when the bottom flange produces the recurvation square, can when the bottom flange produces positive bending moment, can be drawn opposing through the opposing of flange contact pressurized through high-strength bolt.This node is stressed clear and definite, and designing and calculating is easy, and easy construction is quick.
(2) end carriage section 2 realizes welded and high efficient especially easily with middle girder section 3 top flanges, so adopt field Welding, connects and composes with the web bolt and mixes the connected node form.
