Abstract

The utility model provides a pad for welding a box column. A two-section type structure is adopted; one section is bonded on the inner surface of the box column to be welded, and is named as a bonded section; the other section is arranged below a welding line, has a thickness difference with the bonded section towards the welding line, and is named as a welding line section. The pad for welding the box column, provided by the utility model, abandons the rectangular pad in the prior art; as the abnormal pad with thickness difference is adopted, welding agent can be injected in the thickness gap of the pad, and the welding defect dead angle is extended beyond the thickness of a base metal, so that the effective thickness of the welding line-the flaw detection depth is greater than the thickness of the base metal, and the fusion depth requirement of the welding line can be met.

Description

For the liner of welding box-shaped post

Technical field

The utility model relates to steel construction production equipment field, is specifically related to a kind of liner for welding box-shaped post.

Background technology

General welding box-shaped post, adopts welding penetration seam, therefore its bottom needs to install additional liner.Common liner is pane, in welding, easily produce dead angle, the flaw detection degree of depth goes out meeting lower than thickness of slab, and penetration seam flaw detection degree of depth regulation can not be lower than thickness of slab, therefore adopt the liner of pane, the penetration seam flaw detection degree of depth obtaining does not often meet production standard.

Utility model content

For above problems of the prior art, the utility model provides a kind of liner for welding box-shaped post, and the penetration obtaining by it seam flaw detection degree of depth can reach production standard.

The utility model is achieved through the following technical solutions:

For the liner of welding box-shaped post, described liner adopts two-part structure, and one section fits in the inner surface setting of box column to be welded, is called laminating section; Another section is located under weld seam, has the thickness difference towards weld seam with laminating section, is called weld seam section, and the thickness difference of described weld seam section accounts for 2/5～3/5 of laminating section thickness.

The thickness difference of described weld seam section accounts for 1/2 of laminating section thickness.

The surface of described weld seam section is plane.

The surface of described weld seam section is curved surface.

Described weld seam section is large compared with weld seam with respect to the size in the same way of weld seam.

Described liner is steel.

The beneficial effects of the utility model are: the pane liner of having abandoned prior art, there is the special-shaped liner of thickness difference in employing, make the thickness gap of pad can inject welding compound, weld defect dead angle is extended to outside mother metal thickness, the effective thickness of the weld seam degree of depth of detecting a flaw will be greater than the thickness of mother metal like this, can meet the depth of penetration requirement of weld seam.

Accompanying drawing explanation

Fig. 1 is use structural representation of the present utility model;

Fig. 2 is the enlarged diagram at A place in Fig. 1.

In figure: 1 is box column; 2 is weld seam; 3 is laminating section; 4 is welding section.

The specific embodiment

Below in conjunction with the drawings and specific embodiments, the utility model is described in further details.

The utility model provides a kind of liner for welding box-shaped post, adopts two-part structure, and one section fits in the inner surface setting of box column 1 to be welded, is called laminating section 3; Another section is located at weld seam 2 times, and the thickness difference with laminating section 3 exists towards weld seam 2, is called weld seam section 4.Due to the consideration to unitary pad intensity, therefore the thickness difference of weld seam section 4 accounts for 2/5～3/5 of laminating section 3 thickness, but is good mainly with accounting for 1/2 of laminating section 3 thickness.

The combination of more than laminating section 3 and weld seam section 4 can form one and be similar to step-like structure, but the surface of weld seam section 3 can be plane, can be also curved surface, only requires and has thickness gap.

For other of weld seam section 4, requirement is set, its size in the same way with respect to weld seam 2 should be larger compared with weld seam 2, can effectively accept like this welding compound that injects weld seam 2.

Liner can adopt steel material to make, and also can adopt the material of other prior aries to make.

The utility model has been abandoned the pane liner of prior art, there is the special-shaped liner of thickness difference in employing, make the thickness gap of pad can inject welding compound, weld defect dead angle is extended to outside mother metal thickness, the effective thickness of the weld seam degree of depth of detecting a flaw will be greater than the thickness of mother metal like this, can meet the depth of penetration requirement of weld seam.
