Abstract
The utility model relates to a groove-free full-penetration T-shaped welding seam boat-type welding steel member which is characterized by including an H-shaped steel (1) and a cross column (2), the H-shaped steel (1) and the cross column (2) are arranged in a T shape, the gap between the cross column (2) and the welding end of the H-shaped steel (1) is in the range of 2-3mm, and the H-shaped steel (1) which is inclinedly arranged at an inclination angle greater than 45 degrees relative to the horizontal. Compared with the T-shaped welding seam full penetration technology in the prior art, the whole welding process saves two operations of opening grooves and cleaning the end part on the reverse side, therefore, the steel member saves energy and welding materials, reduces the labor intensity of workers, and improves the efficacy; moreover, the steel member meets the requirements on the welding quality, and has lower requirements on the operation level of the workers, as well as is easy in popularization and application.
Description
Technical field
The utility model relates to a kind of square groove full penetration T type weld seam ship type welding steel member, especially relates to the full penetration weld ship type welding steel member of a kind of H shaped steel and cross post.Belong to the construction steel structure welding field.
Background technology
Welded H section steel and the extensive use in high-rise civil building of cross post.For the T type weld seam of full penetration, the traditional welding technological requirement is bevel in the web both sides of cross post, on ship type moulding bed, welds then.Bevelled process lost time and manpower and materials, the groove of offering have also increased the loading of welding wire when welding, this process is inefficiency not only, and the wasting manpower and material resources.
Summary of the invention
The purpose of the utility model is to overcome above-mentioned deficiency, and a kind of welding material waste not only avoided is provided, and helps the square groove full penetration T type weld seam ship type welding steel member that improves effect, alleviate labor strength.
The purpose of the utility model is achieved in that a kind of square groove full penetration T type weld seam ship type welding steel member; It comprises H shaped steel and cross post; Said H shaped steel and cross post are the T type and arrange; Gap between the welding ends of cross post and H shaped steel is 2-3mm, and said H shaped steel is in tilted layout, and the inclination angle of itself and horizontal plane is greater than 45 °.
The web thickness of said H shaped steel and cross post is smaller or equal to 20mm
Compared with prior art, the beneficial effect of the utility model is:
The utility model whole welding process has reduced than traditional T type weld seam full penetration technological requirement offers groove and this two procedures of back root cleaning; Energy and welding material have not only been practiced thrift; Reduced labor strength, improved effect, and welding quality also meets the requirements; Workman's operant level is also required lower, apply easily.

The specific embodiment
As shown in Figure 1; The utility model relates to a kind of square groove full penetration T type weld seam ship type welding steel member; It comprises H shaped steel 1 and cross post 2, and said H shaped steel 1 is the T type with cross post 2 and arranges that the gap between the welding ends of said cross post 2 and H shaped steel 1 is 2-3mm; Said H shaped steel 1 is in tilted layout, and the inclination angle of itself and horizontal plane is greater than 45 °.
Its concrete welding procedure is following:
1), before the assembling greasy dirt, iron rust and moisture in zone to be welded and the both sides 30mm scope are cleaned out like Fig. 1.The fit-up gap is very crucial, and the H shaped steel in the utility model and the web of cross post and flange plate assembly clearance are controlled at 2 ~ 3mm.It is also very important that member is put the inclination angle, and increasing the flange plate inclination angle can be for guaranteeing that weld seam reaches full penetration and increases guarantee together, and the inclination angle can be 60 ± 5 °.
2), hold out against, in weld gap, fill up solder flux 5 then, tossing about to paste steel sleeve 3 and use permanent magnet 4 to hold before the positive welding like Fig. 2 for the T connector of putting.When the web thickness of slab is 20mm, the positive welding of submerged-arc welding parameter: welding current I=830 ~ 850A, arc voltage U=36 ~ 38V, welding speed V=20 ~ 21m/h, parameter constant during the reverse side welding.So each weldering of positive and negative just obtains full penetration T type weld seam together.All the other thin thicknesss of slab are then regulated welding parameter according to actual conditions.The joint that Fig. 3 finishes for positive welding, Fig. 4 is the welding of joint reverse side, the T connector that Fig. 5 finishes for welding.
Claims (2)
1. square groove full penetration T type weld seam ship type welding steel member; It is characterized in that it comprises H shaped steel (1) and cross post (2); Said H shaped steel (1) and cross post (2) are the T type and arrange; Gap between the welding ends of said cross post (2) and H shaped steel (1) is 2-3mm, and said H shaped steel (1) is in tilted layout, and the inclination angle of itself and horizontal plane is greater than 45 °.
2. square groove full penetration T type weld seam ship type welding steel member according to claim 1, the web thickness that it is characterized in that said H shaped steel (1) and cross post (2) is smaller or equal to 20mm.
