Specific embodiment
With reference to embodiments and its attached drawing further explains the present invention.
Embodiment 1
Stiffened column and frame beam steel node connecting structure of the invention, including stiffened column, two bracket plates, eight dowels.
It is the stiffened column and bracket plate setting structure schematic diagram of the embodiment of the present invention referring now to Fig. 1, Fig. 1.As shown,
The stiffened column is cross-shaped profile steel stiffened column 2, and about 3 flange plate of stiffened column welds several row's pegs 1.
Bracket plate structure: consisting of two parts, i.e. plate and A-frame, is steel plate.Plate 4 is wide with a thickness of 20mm
Stiffened column can be met and indulge tendon protective layer thickness 20mm according to live practical adjustment by spending 120mm(), length is with flange plate length, and three
Angle support is right angled triangle, and perpendicular to plate, for supporting plate, being parallel to plate L-square length is 120mm, perpendicular to
Plate L-square length is 150mm, and with a thickness of 20mm, plate, A-frame, flange plate three pass through welded connecting, weld seam
Grade is II grade.The bracket plate plate top surface connecting with Vierendeel girder top muscle is apart from back concrete finished surface 50mm, with Vierendeel girder
The bracket version board bottom identity distance of lower part muscle connection is from beam bottom 20mm.
Fig. 2 is that the dowel of the embodiment of the present invention and stiffened column flange plate weld schematic diagram.Patch weldering dowel: Vierendeel girder mainly by
The Vierendeel girder top upper reinforcement 5(penetrates through vertical muscle, seat shoulder bar), the Vierendeel girder lower part upper reinforcement 6(penetrate through vertical muscle), bearing rod,
The reinforcing bars such as waist muscle (distributing bar and antitorque reinforcing bar), tension rib, hangs muscle composition, wherein the reinforcing bar connecting with stiffened column has top muscle
With lower part muscle.Before 8 top muscle of Vierendeel girder and lower part muscle protrude into the welding of bracket plate face, first in the top muscle and lower part muscle of Vierendeel girder
One end (one end for protruding into stiffened column bracket plate face) patch weldering dowel 7, dowel diameter is the same as Vierendeel girder top muscle or lower part muscle, length
It is firm using preferably being anchored at node for increasing reinforcing bar contact area for 5d.
The sequence of construction of stiffened column and frame beam steel node connecting structure of the invention: the stiffened column with bracket plate is hung
It installs into → checks the verticality of stiffened column → stiffened column is indulged muscle and connected → and bind stiffness column tie-bar → production with patch weldering dowel
Vierendeel girder lower part muscle → installation with patch weldering dowel Vierendeel girder lower part muscle simultaneously be welded in bracket version → make with patch weld
Vierendeel girder lower part muscle of the Vierendeel girder lower part muscle → installation of dowel with patch weldering dowel is simultaneously welded in bracket version.(note: in stiffness
Column and when Vierendeel girder node construction, the side template of Vierendeel girder reserve side so as to the welding and installation of lower part muscle, to be onstructed complete
Cheng Houzai seals the template for reserving side).
Stiffened column and frame beam steel node connecting structure points for attention of the invention
(1) in welding, visual examination does not allow phenomena such as surface pores, slag inclusion, crack occur, and should ensure that weld seam construction matter
Amount.
(2) stiffness structure beam column strength grade of concrete gap is larger, before concreting, in steel corrosion quantity, needs
Expanded sheet metal, angle 30o-60o are being at 1/2 deck-molding of stiffened column.Fig. 3 is the expanded sheet metal angle of the embodiment of the present invention
Schematic diagram is set.
(3) since stiffened column is that cut lengths (three high one hang layer by layer by a two high liftings layer by layer when steel mill makes
Dress), according to the bracket plate that the detailing requiments positioning welding of layer height, Vierendeel girder absolute altitude, bracket plate is arranged, guarantee that error should not mistake
Greatly, it is excessively high or too low relative to frame beam steel to prevent bracket plate, seriously affects beam reinforced steel bar concrete protective thickness
Degree.
The present invention has substantive distinguishing features and significant technological progress, and stiffened column of the invention and frame beam steel node connect
Binding structure is by the way that on steel column flange plate, the steel of weldering dowel is pasted for connection framework beam end side by bracket version positioning welding
Muscle, the node problems that the scene of can effectively solve the problem that encounters, and easily operated and construction overcome node connection anchorage length not
Foot, beam both ends there are the connection that construction Difficulties, the especially Oblique-crossing Frames such as height difference, plate protective layer thickness deficiency are set a roof beam in place with steel column,
Meanwhile the connecting structure strong applicability, be conducive to promote the use of, receive operator and management, the welcome using unit.
Stiffened column of the invention has been used in engineering in practice with frame beam steel node connecting structure, easily operated, matter
Amount guarantees that significant effect has obtained the consistent approval of supervisor, construction unit, received the welcome of operating personnel, achieve
Good economic benefit and social influence.
Above embodiments are used for illustrative purposes only, rather than limitation of the present invention, the technology people in relation to technical field
Member, without departing from the spirit and scope of the present invention, can also make various transformation or variation.Therefore, all equivalent
Technical solution also should belong to scope of the invention, should be limited by each claim.
