Abstract
The utility model belongs to seamless steel pipe apparatus technical field, particularly relates to a kind of six rib seamless steel pipes.The utility model discloses six rib seamless steel pipes, six rib seamless steel pipes comprise cylindrical body, the cross section of described cylindrical body is a rounded face, the inwall of described rounded face is evenly provided with six ribs, six described ribs one end crossing with rounded face inwall forms equilateral six prismatics after being connected, the other end of six described ribs is connected by connecting tube, described connecting tube is connected to form equilateral six prismatics, the jointing place arc transition of described connecting tube and rib, described rib and the length ratio of connecting tube are 1:2.The beneficial effects of the utility model are: reasonable in design, can be good at reaching usage requirement, and durable, stability is better.
Description
Technical field
The utility model belongs to seamless steel pipe apparatus technical field, particularly relates to a kind of six rib seamless steel pipes.
Background technique
Current seamless steel pipe is generally is mostly comparatively regular section bars, and the making for the seamless steel pipe of abnormity also exists larger difficulty, more difficultly produces in batches on a large scale.Common comparatively regular seamless steel pipe is then there is defect in using scope, makes some occasions and special place to use seamless steel pipe.Thus larger restriction and trouble are also existed to the using scope of seamless steel pipe.And the seamless steel pipe of current abnormity is owing to also existing the reasons such as structural design is unreasonable, thus make special-shaped seamless steel pipe be easy to when in use be destroyed, do not reach usage requirement.
Summary of the invention
The purpose of this utility model is to solve above-described technical problem, provides a kind of reasonable in design, and can be good at the six durable rib seamless steel pipes reaching usage requirement, its technological scheme is as follows:
Six rib seamless steel pipes, it is characterized in that, six described rib seamless steel pipes comprise cylindrical body, the cross section of described cylindrical body is a rounded face, the inwall of described rounded face is evenly provided with six ribs, six described ribs one end crossing with rounded face inwall forms equilateral six prismatics after being connected, the other end of six described ribs is connected by connecting tube, described connecting tube is connected to form equilateral six prismatics, the jointing place arc transition of described connecting tube and rib, described rib and the length ratio of connecting tube are 1:2.
Optimal way is, described rib one end crossing with rounded face is semicircular arc, and described semicircular arc is 1:16 with the ratio of the radius of rounded face.
The six rib seamless steel pipes that the utility model provides, when in use, the inwall of described circular pipe is evenly provided with six ribs, six ribs are mainly played a supporting role, and can play good support effect to whole seamless steel pipe.And six ribs one end crossing with rounded face inwall forms equilateral six prismatics after being connected, equilateral six prismatics better can reach supporting effect.Connecting tube mainly plays connection function, the other end of rib is linked together, plays reinforing function.Described rib and the length ratio of connecting tube are 1:2, thus make the support effect of rib and connecting tube more stable.
The further described rib of the utility model one end crossing with rounded face is semicircular arc, and described semicircular arc is 1:16 with the ratio of the radius of rounded face.The effect eliminating seamless steel pipe internal stress can well be played by semicircular arc, make its total more reasonable.
The beneficial effects of the utility model are: reasonable in design, can be good at reaching usage requirement, and durable, stability is better.
Accompanying drawing explanation
Fig. 1 is schematic cross-section of the present utility model.
Embodiment
Embodiment is illustrated below in conjunction with Fig. 1:
As shown in Figure 1, six rib seamless steel pipes, six described rib seamless steel pipes comprise cylindrical body 1, the cross section of described cylindrical body 1 is a rounded face, the inwall of described rounded face is evenly provided with six ribs 3, six described ribs 3 one end crossing with rounded face inwall forms equilateral six prismatics after being connected, the other end of six described ribs 3 is connected by connecting tube 4, described connecting tube 4 is connected to form equilateral six prismatics, described connecting tube 4 and the jointing place arc transition of rib 3, described rib 3 is 1:2 with the length ratio of connecting tube 4.
Optimal way is, described rib 3 one end crossing with rounded face is semicircular arc 2, and described semicircular arc is 1:16 with the ratio of the radius of rounded face.
The six rib seamless steel pipes that the utility model provides, when in use, the inwall of described rounded face is evenly provided with six ribs, six ribs are mainly played a supporting role, and can play good support effect to whole seamless steel pipe.And six ribs one end crossing with rounded face inwall forms equilateral six prismatics after being connected, equilateral six prismatics better can reach supporting effect.Connecting tube mainly plays connection function, the other end of rib is linked together, plays reinforing function.Described rib and the length ratio of connecting tube are 1:2, thus make the support effect of rib and connecting tube more stable.
When in use, be mainly applied to set up as framework in construction industry used.
