Abstract
The utility model discloses a kind of divided edge structure for slab combination beam, the first connector and the second connector including vertical welding, the clearance distance of the welding ends of first connecting plate and the welding position of second connector is 3 5mm, first connector and the second connector are welded for welding bottoming by specialized for carbon dioxide gas protection in the inclined-plane that is provided with that the both sides of the welding ends of first connecting plate are symmetrical formed with divided edge structure, the divided edge structure.The problem of utility model can solve the problem that cold cracking, and meet structure welding fusion penetration and quality requirement.
Description
Technical field
The field that is welded to connect of combination beam is the utility model is related to, is to be related to one kind to be used for slab combination beam specifically
Divided edge structure.
Background technology
The major section of present Welding Composite Beam has I-shaped, H types, π types, T-shaped, box and cast.Drilling machine module is commonly used
The H types beam of partial penetration weld seam and the T-shaped beam of full penetration weld, material DH36, EH36.The concrete specification is as shown in Figure 1.
But when combination beam H profile steel web thickness for 38mm and more than, when edge of a wing plate thickness be 50mm and the above, weld
When stitching fusion penetration more than 14mm, after using submerged arc welding with above groove, weld penetration can not reach requirement.It is so groove is deep
Degree increases to 15mm, is welded again.But it is impossible to meet design requirement.
In order to meet fusion penetration requirement, the design of groove is further changed, and sheet separation distance is increased, but gap
Increase, directly easily form weldering using submerged arc welding and leak phenomenon, and weld seam is easy to crack.
Utility model content
The purpose of this utility model is to overcome deficiency of the prior art, there is provided a kind of slope for slab combination beam
Mouth structure, the problem of cold cracking can solve the problem that by the utility model, and meet structure welding fusion penetration and quality requirement.
The purpose of this utility model is achieved through the following technical solutions：
A kind of divided edge structure for slab combination beam, include the first connector and the second connector of vertical welding, institute
The clearance distance for stating the welding ends of the first connecting plate and the welding position of second connector is 3-5mm, the first connecting plate
The both sides of welding ends it is symmetrical be provided with inclined-plane formed with divided edge structure, the divided edge structure is used for by specialized for carbon dioxide gas protection weldering
First connector and the second connector are welded in bottoming.
Angle between the inclined-plane and the second connector horizontal direction is 45 °.
The depth of the divided edge structure is at least 15mm.
Filled on the outside of the specialized for carbon dioxide gas protection weldering bottoming by submerged-arc welding.
Compared with prior art, beneficial effect caused by the technical solution of the utility model is：
1st, the structure increases fusion penetration because changing groove parameter, solid and reliable after slab combination beam for welding, will not
Fracture；
2nd, increase gas shield welding bottoming, effectively prevent weldering leakage and the generation of cold crack caused by gap increases, reducing should
Power is concentrated, and increases the intensity of combination beam.
3rd, add qualification rate, the matters such as reduction is done over again, save human and material resources and time.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the argument structure schematic diagram of specific embodiment.
Fig. 3 is for the configuration state figure after the welding of H profile steel beam in specific embodiment.
Reference：The connectors of 1- first, the connectors of 2- second, 3- inclined-planes
Embodiment
The utility model will be further described below in conjunction with the accompanying drawings.
As shown in figure 1, a kind of divided edge structure for slab combination beam, including the first connector 1 of vertical welding and
The clearance distance of the welding position of two connectors 2, the welding ends of the first connecting plate 1 and the second connector 2 is 3-5mm, and first connects
The both sides of the welding ends of fishplate bar 1 it is symmetrical be provided with inclined-plane 3 formed with divided edge structure, divided edge structure is used to pass through carbon dioxide gas
Protect weldering bottoming and weld the first connector 1 and the second connector 2.
As shown in Figures 2 and 3, for the present embodiment by taking the wing plate and web of welded H section steel as an example, i.e. the first connector 1 is abdomen
Plate, the second connector 2 are wing plate,
When combination beam H profile steel web thickness T2 for 38mm and more than, when edge of a wing plate thickness T1 is 50mm and the above, weld seam
When fusion penetration is more than 14mm, in order to meet combined beam structure intensity requirement, fusion penetration needs to reach 14mm.In order to reach design fusion penetration,
Need groove being improved, the depth h of divided edge structure increases to 15mm, in addition, should also increase between wing plate and web
Stand-off distance is from increasing to 3-5mm by original 0-1mm, further increase fusion penetration.A, b, c, d are respectively specialized for carbon dioxide gas protection in Fig. 2
The welding sequence of weldering, backing welding can avoid weldering from leaking, and effectively prevent the generation of defect.
Table 1 is welding procedure details in the present embodiment concrete operations, illustrates specialized for carbon dioxide gas protection weldering and submerged-arc welding
Specific data parameters and welding sequence.
