Abstract
The utility model is related to tubing technical field, more particularly to a kind of axially hollow Double-layer pipe, including internal layer and outer layer, connected between internal layer and outer layer by supporting construction, the roughly triangular supporting construction of supporting construction, with three summits, respectively the first summit, the second summit and the 3rd summit, when the first summit of supporting construction and internal layer are connected, then the second summit and the 3rd summit are connected with outer layer；When the first summit of supporting construction and outer layer are connected, then the second summit and the 3rd summit are connected with internal layer.Due to rational structure design, by the direction for changing original reinforcement so that using stable triangular support structure connection between Inner tubing layers and outer layer, hence it is evident that improve the compression strength and rigidity of tubing.Tubing integrally saves material, lightweight, and rigidity is high, and easy construction can withdraw reuse.
Description
Technical field
The utility model is related to tubing technical field, more particularly to a kind of axially hollow Double-layer pipe.
Background technology
The tubing of buried pipeline is usually pipe of cement or is directly brickwork construction in conventional water discharger for road,
Weight weight, construction is also inconvenient.Managed so occurring in that now using hard polyvinyl chloride pipe as drainage pipeline and inspection shaft
Material.This hard polyvinyl chloride pipe is all solid-wall pipe, the phase of the tubing and cement or brickwork construction of unit length during beginning
Weight/power ratio mitigates significantly, but still very heavy, in order to further mitigate weight construction is more facilitated, occurs in that hollow tube
Material, this hollow tubular product has to be connected (as shown in Figure 1) between inside and outside two layers of tube wall, tube wall by shaft orientation reinforcing rib 4.This knot
The tubing weight of structure mitigates significantly, has saved processing raw material for tubing.But the Double-layer pipe of this structure is receiving outside
During lateral compression, it is easy to deform, structural strength still has much room for improvement, to adapt to more severe use environment.
Utility model content
The technical problems to be solved in the utility model is：In order to further improve the structural strength of Double-layer pipe, raising makes
With the life-span, the utility model provides a kind of axially hollow Double-layer pipe.
The utility model solves the technical scheme that its technical problem used：A kind of axially hollow Double-layer pipe, including
Internal layer and outer layer, are connected between internal layer and outer layer by supporting construction, the roughly triangular supporting construction of the supporting construction,
With three summits, respectively the first summit, the second summit and the 3rd summit, when the first summit of supporting construction and internal layer connection
When, then the second summit and the 3rd summit are connected with outer layer；When the first summit of supporting construction and outer layer are connected, then second push up
Point and the 3rd summit are connected with internal layer.
The utility model using triangle supporting construction connection internal layer and outer layer, that is, will be axial in the prior art
Reinforcement be changed to oblique reinforcement, adjacent oblique reinforcement incline direction on the contrary, and have a common end points, i.e., can
The supporting construction of triangle is constituted with internal layer or outer layer.Therefore, on the premise of reinforcement quantity is not increased, only change and add
The direction of strengthening tendons is that can reach the effect for improving tubing intensity.
Further, for utilization space, supporting construction is set more, preferably, the internal layer and outer layer be provided with it is multiple
The supporting construction of triangle, the supporting construction of two adjacent triangles shares a line.
Further, in order to reach optimal intensity effect, the supporting construction substantially equilateral triangle of the triangle.
The beneficial effects of the utility model are, axially hollow Double-layer pipe of the present utility model, because rational structure is set
Meter, by the direction for changing original reinforcement so that connected between Inner tubing layers and outer layer using stable triangular support structure
Connect, hence it is evident that improve the compression strength and rigidity of tubing.Tubing integrally saves material, lightweight, and rigidity is high, easy construction,
It can withdraw and reuse.
Brief description of the drawings
The utility model is further illustrated with reference to the accompanying drawings and examples.
Fig. 1 is existing tubing sectional view.
Fig. 2 is the structural representation of the utility model optimum embodiment.
In figure：1st, internal layer, 2, outer layer, 3, supporting construction, 4, shaft orientation reinforcing rib.
Embodiment
The utility model is described in further detail presently in connection with accompanying drawing.These accompanying drawings are simplified schematic diagram,
Only illustrate basic structure of the present utility model in a schematic way, therefore it only shows the composition relevant with the utility model.
As shown in Fig. 2 be the utility model optimum embodiment, including internal layer 1 and outer layer 2, lead between internal layer 1 and outer layer 2
Cross supporting construction 3 to connect, the roughly triangular supporting construction of supporting construction 3, with three summits, respectively the first summit,
Second summit and the 3rd summit, when the first summit of supporting construction 3 and internal layer 1 are connected, then the second summit and the 3rd summit with
Outer layer 2 is connected；When the first summit of supporting construction 3 and outer layer 2 are connected, then the second summit and the 3rd summit and the phase of internal layer 1
Connection.Internal layer 1 and outer layer 2 are provided with the supporting construction of multiple triangles, and the supporting construction of two adjacent triangles shares one
Bar side.The supporting construction of triangle substantially equilateral triangle.Because internal layer 1 and outer layer 2 are annular shape, and triangular support
It is certain section of cambered surface on internal layer 1 or outer layer 2 to have a line in structure, therefore, has a line in the supporting construction of triangle somewhat
With some radians, but integrally still have a generally triangular shape structure.
Using it is above-mentioned according to desirable embodiment of the present utility model as enlightenment, pass through above-mentioned description, related work people
Member can carry out various changes and amendments in the range of without departing from this utility model technological thought completely.This reality
The content on specification is not limited to new technical scope, it is necessary to its technology is determined according to right
Property scope.
