Abstract

The utility model discloses a profile, which is characterized in that the profile is composed of three edges with lambdoidal cross section. Compared with the materials of the prior angle profile, the transverse and the longitudinal compression resistances are greatly improved due to the addition of one edge. Proven by the contrast experiments, the compression resistance ability of the profile along the diagonals and two ends is twice higher than that of the prior angle profile material. The strength can be substantially increased and the anti-disaster capability is improved by adopting the profile of the utility model to construct various steel towers, crane towers, other production facilities and some articles for daily life use.

Description

A kind of section bar

Technical field

The utility model belongs to material, is specifically related to a kind of section bar.

Background technique

In the existing section bar, angle section material (as angle steel, angle type aluminium and angle shape material etc.) is a kind of gauge material that is widely used in power communication equipment, civil building and other production facility and some daily necessities in a large number.The characteristics of this material are, are far longer than other section bars such as sheet material, wire rod along the anti-pressure ability (referring to Fig. 1) on two limits, and are far smaller than along the anti-pressure ability on two limits along the anti-pressure ability (referring to Fig. 2, Fig. 3) at its diagonal and two ends.When the object that makes up with the angle section material was subjected to weight, in case surpass the limit of its anti-pressure ability along the pressure at this material diagonal and two ends, this material will bend, and causes object to collapse.

The model utility content

The purpose of this utility model is to provide anti-pressure ability better section bar.

Realize that above-mentioned model utility purpose technological scheme is: section bar is made up of three limits of section behaviour word shape.

Described section bar, one of them limit is positioned on the bisectrix of other two angles that the limit forms for the ridge limit.

Described section bar, two formed angles in limit are the right angle.

Described section bar, the lateral length on one of them limit are less than or equal to the lateral length on two limits in addition.

Described section bar can adopt mode hot-forming, cold moudling to make; Also can have two section bars that form obtuse angle edge to combine by two, the limit of these two section bar correspondences combines by bolt, riveted joint or welding manner.

Described section bar, the thickness on ridge limit is greater than the thickness on other limit.

The utility model and existing angle section material compare, owing to increased a limit, horizontal and vertical anti-pressure ability is significantly improved, and prove through the contrast experiment, and existing angle section material improves more than the twice along the anti-pressure ability at its diagonal and two ends.Adopt the utility model section bar to make up all kinds of iron towers, tower crane, reach other production facility and some daily necessities, can increase considerably intensity, improve anti-disaster ability.

Further specify the technical solution of the utility model below in conjunction with accompanying drawing.

Embodiment

As Fig. 4, shown in Figure 5, the utility model section bar is made up of three

limits

1,2 of section behaviour word shape, one of them limit 2 by the ridge limit be positioned at two limits 1 in addition on the bisectrix 3 of formation angle α, two limit 1 formed angle α are the right angle, the lateral length L1 on limit 2 is less than the lateral length L2 on other two limits 1, and the thickness on limit 2 is twices of other limit 1 thickness.

As shown in Figure 6, the utility model by two have two form obtuse angle edge 1,2 ' section bar combines, the limit 2 ' of these two section bar correspondences combines by bolt 4.
