Problems solved by technology

At present, the square tube structure commonly used in structural design has a box-shaped cross section. When the square tube structure needs to bear large stress in the equipment, the method of increasing the wall thickness is usually adopted to improve its compression resistance, bending resistance, and resistance to stress. Torsional strength and rigidity, which will inevitably lead to increased weight, waste of raw materials and increased cost

Embodiment 1

[0014] Such as figure 1 As shown, the square cylinder structure of the present invention includes an outer cylinder 1, an inner cylinder 2, a reinforced vertical rib 3, and an angle vertical rib 4; the inner cylinder 2 is a cylinder with a circular cross section; the outer cylinder 1 passes four Corner vertical ribs 4 and eight reinforced vertical ribs 3 are connected with inner tube 2 , one end of four corner vertical ribs 4 is respectively connected with four corners 5 of outer tube 1 , and the other end is connected with inner tube 2 respectively. Eight reinforcing vertical ribs 3 are respectively perpendicular to the four side walls of the outer cylinder 1, and each corner vertical rib 4 forms two tubular bodies with approximately triangular cross-sections with the outer cylinder 1 and two adjacent reinforcing vertical ribs 3 respectively. Since the reinforcing vertical rib 3 is perpendicular to the side wall, the compressive and bending strength of the square tube structu...

Embodiment 2

[0016] Such as figure 2 As shown, the square cylinder structure of the present invention includes an outer cylinder 1, an inner cylinder 2, a reinforced vertical rib 3, and a corner vertical rib 4; the inner cylinder 2 is a square tube in section; the outer cylinder 1 passes through four corners The vertical ribs 4 and eight reinforced vertical ribs 3 are connected with the inner cylinder 2, one end of the four corner vertical ribs 4 is respectively connected with the four corners 5 of the outer cylinder 1, and the other end is connected with the four corners 6 of the inner cylinder 2 respectively. Eight reinforcing vertical ribs 3 are respectively perpendicular to the four side walls of the outer cylinder 1, and each corner vertical rib 4 forms two tubular bodies with approximately triangular cross-sections with the outer cylinder 1 and two adjacent reinforcing vertical ribs 3 respectively. Since the reinforcing vertical rib 3 is perpendicular to the side wall, the compressi...

Abstract

The invention discloses a square cylinder structure which comprises an external cylinder, an internal cylinder, a reinforced vertical steel bar and an angle vertical steel bar. The external cylinder is connected with the internal cylinder via the angle vertical steel bar and the reinforced vertical steel bar, and the angle vertical steel bar and the reinforced vertical steel bar as well as the external cylinder form a tubular body with the approximate triangular cross section. Under the condition of the less weight addition, the invention can promote the compression strength, the bending strength, the anti-twisting intensity and stiffness, considerably save the original material, has the advantages of simple structure, light weight and low cost, can be widely applied on the field of the structure design.

Description

technical field [0001] The invention relates to a square tube structure. Background technique [0002] In our country, with the continuous development of economic technology and science and technology, the requirements for the structural design of various equipment are getting higher and higher. Under the conditions, it has the characteristics of simple structure, light weight and low cost. [0003] The square tube structure is widely used in the structural design of equipment, such as columns, bases, beams and supporting walls. In different applications, the square tube structure may bear compressive stress, bending stress, torsional stress, or both of the above stresses or even the above three stresses at the same time. At present, the square tube structure commonly used in structural design has a box-shaped cross section. When the square tube structure needs to bear large stress in the equipment, the method of increasing the wall thickness is usually adopted to improve ...
