Abstract
The utility model provides a kind of outer muscle enhancing internally finned tube.The outer muscle enhancing internally finned tube includes tube body, outer rib equipped with internal-rib, and the outer rib is wound in the tube body, the gap between the internal-rib, and the cross section of the outer rib is " T " shape structure.The outer muscle enhancing internally finned tube provided by the utility model solves the internally finned tube of the prior art, and there are weakness, and by the way that the technical issues of outer muscle pipe enhancing weakness will lead to weight gain, cost increase is arranged.
Description
Technical field
The utility model relates to internally finned tube fields, and in particular to a kind of outer muscle enhancing internally finned tube.
Background technique
As the paces of urban construction are accelerated, drainpipe using more and more extensive, an important parameter of drainpipe refers to
Mark is exactly ring stiffness, and ring stiffness is important indicator of the drainpipe in underground receiving radial forces.Ring stiffness height indicates draining
Manage it is buried after radial endurance greatly improve, that is to say, that safety is higher after drainpipe is buried, and a possibility that conquassation reduces.
Increase ring stiffness, can also be realized by increasing material utilization amount by increasing pipeline wall thickness.But material
The weight of tubing can be aggravated after material dosage increase, tubing cost increases, and transportation cost can also rise.Then occur internally finned tube,
More ribbed pipes etc., make improvements on structural pipe wall, to enhance the design of performance.
But this structure acts on very little to the raising really to ring stiffness.The ring stiffness of tubing is rigid with the ring of most weak part
Subject to degree, although the Hollow raised section of internal-rib improves the ring stiffness of pipe entirety, but the position between lug boss become it is weak
Point becomes the security risk of tubing.
By winding an outer muscle pipe of circle between internal-rib, it can effectively enhance the intensity of tubing weakness, and then improve pipe
The ring stiffness of material entirety.But it outer muscle pipe is set has also resulted in the dosage of material and increase, aggravated tubing weight, increased costs,
Transportation cost also rises.
Utility model content
For the internally finned tube that solves the prior art, there are weakness, and by be arranged outer muscle pipe enhancing weakness will lead to weight gain,
The technical issues of cost increase, the utility model provide a kind of outer muscle enhancing internally finned tube to solve the above problems.
A kind of outer muscle enhancing internally finned tube, the tube body including being equipped with internal-rib are additionally provided with outer rib, the outer rib is wound in institute
Tube body is stated, the gap between the internal-rib, the cross section of the outer rib is " T " shape structure.
In a kind of preferred embodiment of outer muscle enhancing internally finned tube provided by the utility model, the outer rib includes top
Face, reinforcing rib, the both ends of the top surface are connect with the internal-rib of its two sides respectively, and described reinforcing rib one end and the top surface connect
It connects, the other end is connect with the tube body.
In a kind of preferred embodiment of outer muscle enhancing internally finned tube provided by the utility model, the top surface is arched top
Face, to the side protrusion far from the tube body.
In a kind of preferred embodiment of outer muscle enhancing internally finned tube provided by the utility model, the outer rib includes a plurality of
The reinforcing rib, equal one end are connect with the top surface, and the other end is connect with the tube body.
In a kind of preferred embodiment of outer muscle enhancing internally finned tube provided by the utility model, the top surface and the internal-rib
Joint face, the joint face of the reinforcing rib and the tube body widens in junction, increases contact area.
In a kind of preferred embodiment of outer muscle enhancing internally finned tube provided by the utility model,
Compared to the prior art, the outer muscle enhancing internally finned tube provided by the utility model is equipped with the outer rib, compares
It is saved generally in the effective material of outer muscle of the prior art.Effectively alleviate the increase of material utilization amount caused by practical outer muscle pipe, pipe
The problems such as material weight, increased costs, transportation cost rises.
The top of arc is equipped with described in the outer muscle enhancing internally finned tube provided by the utility model using the outer rib
Face and the reinforcing rib.Compared to the structure of common hollow outer muscle pipe, there is better reinforcing effect.
Detailed description of the invention
Fig. 1 is the partial longitudinal section figure of outer muscle enhancing internally finned tube provided by the utility model in embodiment 1；
Fig. 2 is the partial longitudinal section figure of outer muscle enhancing internally finned tube provided by the utility model in example 2.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describing, it is clear that described embodiment is only a part of the embodiment of the utility model, rather than whole
Embodiment.
Embodiment 1:
Referring to Fig. 1, being the partial longitudinal section figure of outer muscle enhancing internally finned tube 1 provided by the utility model in embodiment 1.
The outer muscle enhancing internally finned tube 1 is made of internally finned tube 12, the outer rib 13 for being wound in the internally finned tube 12.
The internally finned tube 12 is equally formed by the hollow profiled material winding of strip, gluing, and the hollow profiled material includes
Tube wall 21, internal-rib 22.The structure of the internally finned tube 12 and the prior art it is consistent, therefore not to repeat here.
The outer rib 13 is wound in the position in the gap between the internal-rib 22 of the internally finned tube 12, including arc
The reinforcing rib 32 of top surface 31, two.
The two sides of the top surface 31 are connect with the internal-rib 22 of two sides respectively, raised direction also with the internal-rib 22 1
It causes, but height is lower than the internal-rib 22.Two reinforcing ribs 32 are parallel to each other, and one end is connect with the top surface 31, separately
One end is connect with the tube wall 21.
Embodiment 2:
Referring to Fig. 2, being the partial longitudinal section figure of outer muscle enhancing internally finned tube 1 provided by the utility model in example 2.
The outer muscle enhancing internally finned tube 1 is made of internally finned tube 12, the outer rib 13 for being wound in the internally finned tube 12.
