Description

A kind of steel work spandrel girder

Technical field

The utility model relates to a kind of steel structure girder, particularly relates to a kind of steel work spandrel girder.

Background technology

Beam is engineering structures, skeleton in machinery, building and being widely used, and it bears the power of transverse bending, is the necessity in daily life.Beam as a whole in a part, can, as independently stressed thing, be also vital.Its power that must bear is the bigger the better, but own wt is little as far as possible, and this will carry out designing and stressed analysis to beam, design best beam.

Utility model content

The steel structure girder that the technical problem that the utility model mainly solves is to provide not only uses economic arrangement, greatly saves material and man-hour, and has great space and remove to meet machinery, electrically and the needs of miscellaneous equipment.

In order to solve the problem, the utility model provides a kind of steel work spandrel girder, it is characterized in that: comprise Vierendeel girder and some triangular beam, described Vierendeel girder and triangular beam adopt same steel matter, and described Vierendeel girder and the angled distribution of described triangular beam, described Vierendeel girder and described triangular beam adopt the mode of melting welding to be connected, and described triangular beam is positioned at the inside of Vierendeel girder all the time, the head and the tail distribution successively of described triangular beam.Described steel work spandrel girder can bear larger power than beam in the past, more firm, stable, and is the layout of economy, great saving material and man-hour, has larger space and removes to meet the needs placing mechanical, electric and other equipment.

Steel work spandrel girder disclosed in the utility model, described triangular beam becomes isosceles triangle.Use the triangular beam of isosceles triangle in the inside of Vierendeel girder, make beam uniform stressed when stressed.The shape that triangle is inherently the most stable, in order to allow beam not easy fracture, uniform force, isosceles triangle is best selection.

Steel work spandrel girder disclosed in the utility model, the triangle base angle of described triangular beam is 30 ° ~ 45 °.The span of triangular beam can be made so large, but do not affect stressed, indirectly reduce the loss of material.

Steel work spandrel girder disclosed in the utility model, described Vierendeel girder and the connected mode of triangular beam are melting welding.

Steel work spandrel girder disclosed in the utility model, described triangular beam becomes head and the tail distribution successively.Make uniform force like this.

Compared with prior art, the beneficial effects of the utility model are that this steel work spandrel girder can bear larger power than beam in the past, more firm, stable, stressed even everywhere, and be economic layout, great saving material and man-hour, there is larger space and remove to meet the needs placing mechanical, electric and other equipment.

Detailed description of the invention

Below in conjunction with the drawings and specific embodiments, illustrate the utility model further, following detailed description of the invention should be understood and be only not used in restriction scope of the present utility model for illustration of the utility model, after having read the utility model, the amendment of those skilled in the art to the various equivalent form of values of utility model has all fallen within the application's claims limited range.

With reference to Fig. 1, this steel work spandrel girder, comprise Vierendeel girder 1 and some triangular beam 2, described Vierendeel girder 1 and triangular beam 2 adopt same steel matter, and described Vierendeel girder 1 and the angled distribution of described triangular beam 2, described Vierendeel girder 1 adopts the mode of melting welding to be connected with described triangular beam 2, and described triangular beam 2 is positioned at the inside of Vierendeel girder 1 all the time, the head and the tail distribution successively of described triangular beam 2.

Preferred as one, described triangular beam is isosceles triangle.Use the triangular beam of isosceles triangle in the inside of Vierendeel girder, make beam uniform stressed when stressed.The shape that triangle is inherently the most stable, hocketing of isosceles triangle is stressed, and keeping uniform force, is best selection.

Preferred as one, the triangle base angle of described triangular beam is 30 ° ~ 45 °.The span of triangular beam can be made so large, but do not affect stressed, the loss indirectly reducing material makes beam firmer, firm.

Preferred as one, described Vierendeel girder and the connected mode of triangular beam are melting welding.Make contact point stressed after there is no deformation, stable.

Preferred as one, described triangular beam becomes head and the tail distribution successively.Make uniform force like this.

With reference to Fig. 2, Fig. 3, Fig. 4, carry out the contrast of force analysis.The utility model is very economical on arrange, the contact point in inside is also fewer, and this just can save material and man-hour greatly.Also great space is had to go to meet the needs placing machinery and other equipment.Not only large by pressing the power of bearing at beam, also can be stressed in transverse direction.Compared with Fig. 3, the utility model contact point is few, saves material.Compared with Fig. 4, the utility model can be subject to certain horizontal power.
