Abstract
The utility model provides a high strength special section tube, which belongs to the technical field of welding pipes, and solves the problems that existing special section tubes are not large in strength and easy to fracture. The high strength special section tube is a hollow tube which is enclosed by flat walls and circular arc walls which are connected on the two ends of the flat walls, two reinforcing ribs are axially arranged on the outer walls of the circular arc walls, a plurality of through holes are arranged on the circular arc walls, and support columns are connected between the circular arc walls and the flat walls. The high strength special section tube has the advantages of strong bearing capacity and shock resistance.
Description
Technical field
The utility model relates to a kind of steel tubing in different shapes, is specifically related to a kind of high-intensity special-shaped pipe.
Background technique
Steel tubing in different shapes is generally distinguished according to disconnected cross section.Traditional circular hollow section shape is limited, there is certain narrow limitation, cannot be for some specified conditions and environment, in current construction and decoration, engineering machinery, often adopt aluminium alloy shaped-tube, and steel tubing in different shapes has more Economic Section advantage, adapts to the particularity of service condition, can save metal, improve stock utilization, simplify manufacturing process, raise labour productivity; Steel tubing in different shapes is compared with pipe, and steel tubing in different shapes is all better than pipe in overall appearance moulding and the design concept of product, is meeting under the conditions such as equal usability, and steel tubing in different shapes can alleviate structure weight greatly; Moment of inertia and the section modulus of pipe are less, are being subject under the condition of plane bending and distortion, are not so good as steel tubes resistance to flexure and anti-twist ability large; Pipe and the steel tubing in different shapes of the same length of side and diameter, steel tubing in different shapes bearing capacity and shock resistance are better.
Although steel tubing in different shapes is larger than the resistance to flexure of pipe and anti-twist ability, many times steel tubing in different shapes need to bear axially and the power of all directions such as radially, and the intensity of existing steel tubing in different shapes still cannot be born, and outer wall easily produces tiny distortion and even breaks.
Summary of the invention
The purpose of this utility model is the problems referred to above that exist for prior art, has proposed the steel tubing in different shapes that a kind of bearing capacity and shock resistance are strong.
The purpose of this utility model can realize by following technical proposal: a kind of high-intensity special-shaped pipe, described steel tubing in different shapes is the hollow tube being surrounded by planomural and the circular arc wall that is connected in planomural two ends, on described circular arc wall outer wall, be axially arranged with two stiffening ribs, in described circular arc wall, offer some through holes, between described circular arc wall and planomural, be connected with supporting post.
In above-mentioned a kind of high-intensity special-shaped pipe, described through-hole diameter is much smaller than circular arc wall arc length.
In above-mentioned a kind of high-intensity special-shaped pipe, described supporting post top and bottom lay respectively at planomural and circular arc wall neutral position.
In above-mentioned a kind of high-intensity special-shaped pipe, central angle corresponding to described circular arc wall arc length is acute angle.
In above-mentioned a kind of high-intensity special-shaped pipe, described planomural and circular arc wall all adopt Q345B steel to make.Cryogenic property, cold stamping, weldability and machinability are all very good.
Compared with prior art, the utlity model has following advantage:
1, described circular arc wall two ends are axially arranged with stiffening rib near circular arc wall and planomural joint and can strengthen the axial strength of steel tubing in different shapes, make steel tubing in different shapes axial strength higher;
2, in circular arc wall, offer some through holes, between described circular arc wall and planomural, be connected with supporting post, through hole can discharge the power that circular arc wall is subject to, and circular arc wall part can be out of shape, supporting post can be strengthened steel tubing in different shapes strength radially, makes steel tubing in different shapes radial strength higher;
3, planomural and circular arc wall all adopt Q345B
Steel is made.Cryogenic property, cold stamping, weldability and machinability are all very good.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model one preferred embodiment.
Fig. 2 is the sectional view of the utility model one preferred embodiment.
In figure, 1, planomural; 2, circular arc wall; 3, stiffening rib; 4, supporting post; 5, through hole.
Embodiment
Be below specific embodiment of the utility model by reference to the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiments.
As shown in Figure 1-2, this high-intensity special-shaped pipe is the hollow tube being surrounded by planomural 1 and the circular arc wall 2 that is connected in planomural 1 two ends, described circular arc wall 2 two ends are axially arranged with two stiffening ribs 3 near circular arc wall 2 and planomural 1 joint, can strengthen the axial strength of steel tubing in different shapes, make steel tubing in different shapes axial strength higher, in described circular arc wall 2, offer some logical 5 holes, between described circular arc wall 2 and planomural 1, be connected with supporting post 4, through hole 5 can discharge the power that circular arc wall 2 is subject to, circular arc wall 2 parts can be out of shape, supporting post 4 can be strengthened steel tubing in different shapes strength radially, make steel tubing in different shapes radial strength higher.
As preferably, through hole 5 diameters are much smaller than circular arc wall 2 arc length, when circular arc wall 2 is born radially or during axial power, circular arc wall 2 is local, and small deformation can occur, offer a plurality of very little through holes 5 and can discharge stressedly, and small through hole 5 can not exert an influence to circular arc wall 2 rigidity.
As preferably, supporting post 4 top and bottom lay respectively at the neutral position of planomural 1 and circular arc wall 2, and when circular arc wall 2 is subject to power radially, the supporting post 4 in the middle of being positioned at can be so that the left one side of something of circular arc wall 2 and right one side of something be stressed quite, connection and reasonable arrangement.
As preferably, central angle corresponding to circular arc wall 2 arc length is acute angle, and it is shorter that arc pushes up the maximum distance of planomural, is less than radius of arc, planomural 1 and circular arc wall 2 all adopt Q345B steel to make, and cryogenic property, cold stamping, weldability and machinability are all very good.The steel tubing in different shapes of this shape and material can bear larger power.
This high-intensity special-shaped pipe, by structural improvement, makes this steel tubing in different shapes can bear larger power, more firm, long service life.
Specific embodiment described herein is only to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various modifications or supplements or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
