Description

Steel construction box post roof beam

Technical Field

The utility model relates to a steel construction prefabricated component field specifically indicates a steel construction box post roof beam.

Background

At present, a steel-structure box-type column beam is generally formed by cutting a steel plate with a fixed width in a steel mill into two webs and two wing plates and then welding four steel plates in a surrounding manner, so that the production cost is high, the welding quantity is large, the manufacturing speed is low, the technical requirement of fusion penetration welding is difficult to meet, and the reliability of a welding seam is poor.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is to overcome the defect of above-mentioned technique, provide a steel construction box post roof beam.

For solving the technical problem, the utility model provides a technical scheme is a steel construction box column roof beam: the steel plate comprises symmetrically arranged steel plates, wherein 2 steel plates are connected through welding; the two ends of the steel plate are bent towards the same direction to form a first bent part and a second bent part, the first bent part and the second bent part are the same in length, the first bent part and the second bent part form an included angle of 90 degrees with the main body of the steel plate, the first bent parts of 2 steel plates are flush, the second bent parts of 2 steel plates are flush, the 2 first bent parts are fixedly connected at the lap joint through flat welding, and the 2 second bent parts are fixedly connected at the lap joint through flat welding; the thickness of the steel plate is more than 14 mm.

As a modification, the steel plate forms an arc-shaped bend at the opposite outer side of the bend.

Compared with the prior art, the utility model the advantage lie in: the utility model discloses changing original four bibliographic categories branch welding into two parts welding, the fillet welding improves to the open position welding, and the welding volume reduces, and welding quality and technology are controlled more easily, and work efficiency improves, and box post roof beam corner is curved for the camber simultaneously, and stress dispersion can not appear concentrated stress, and the corner is the parent metal, is not destroyed, and is rational in infrastructure, is difficult for hindering the people.

Drawings

Fig. 1 is the utility model relates to a structural schematic diagram of steel construction box column roof beam.

As shown in the figure: 1. the steel sheet, 1.1, first kink, 1.2, second kink, 1.3, arc type is bent, 2, welding seam.

Detailed Description

The following will combine the attached drawings to further explain in detail the steel structure box type column beam of the present invention.

With reference to the attached drawing 1, the steel structure box type column beam comprises steel plates 1 which are symmetrically arranged, wherein the steel plates 1 are connected through welding; two ends of the steel plate 1 are bent towards the same direction to form a first bent part 1.1 and a second bent part 1.2, the lengths of the first bent part 1.1 and the second bent part 1.2 are the same, the first bent part 1.1 and the second bent part 1.2 form an included angle of 90 degrees with the main body of the steel plate 1, the first bent parts 1.1 of 2 steel plates 1 are flush, the second bent parts 1.2 of 2 steel plates 1 are flush, the first bent parts 1.1 are fixedly connected at the lap joint through flat welding, and the second bent parts 1.2 are fixedly connected at the lap joint through flat welding; the thickness of the steel plate 1 is more than 14 mm.

The steel plate 1 forms an arc-shaped bend 1.3 at the opposite outer side of the bend.

The utility model discloses when concrete implementation, the specification of the steel construction box post roof beam of making as required, select steel sheet 1 with the equal length of steel construction box post roof beam, 1 width of steel sheet equals half of steel construction box post roof beam girth, pre-groove all around, adopt kiloton level bender to bend two steel sheet 1 respectively, make first kink 1.1, second kink 1.2 is half of the width of steel construction box post roof beam, because 1 thickness of steel sheet is greater than 14mm, the department of bending forms curved 1.3 of camber, be difficult for hindering the people, and there is pre-groove at the port at steel sheet 1, make things convenient for hou mian welding, with two steel sheet 1 butt joints, because there is the groove, only need to put the face of weld level up the back of piecing together, adopt automatic submerged arc welding's mode to weld can.

The utility model discloses changing original four bibliographic categories branch welding into two parts welding, the fillet welding improves to the open position welding, and the welding volume reduces, and welding quality and technology are controlled more easily, and work efficiency improves, and box post roof beam corner is curved for the camber simultaneously, and stress dispersion can not appear concentrated stress, and the corner is the parent metal, is not destroyed, and is rational in infrastructure, is difficult for hindering the people.

The present invention and the embodiments thereof have been described above, and the description is not limited thereto, and the illustration in the drawings is only one of the embodiments of the present invention, and the actual structure is not limited thereto, for example, the width of the steel plate 1 can be adjusted to 5/12 of the circumference, and the width of the steel plate 2 can be adjusted to 7/12 of the circumference, and then butt-welded. In summary, those skilled in the art should understand that they should not be limited to the embodiments described above, and that they can design the similar structure and embodiments without departing from the spirit of the invention.
