Abstract
A kind of two internal-rib strengthens winding structure pipe, comprise body and the profile shapes unit being arranged at tube wall, profile shapes unit comprises and the bottom of tube wall welding one and the stiffening rib being arranged at two bottom sides edge, stiffening rib comprises allotment bearing portion, transition part and circular arc support, the upper end of allotment bearing portion and circular arc support utilizes transition part to integrally combine, the lower end of allotment bearing portion and circular arc support all links with the bottom of profile shapes unit and is integrated, and allotment bearing portion is perpendicular to the bottom of profile shapes unit; Profile shapes unit is helically wound around on tube wall, and utilizes sol layer to combine between the adjacent straight support of different circle profile shapes unit, forms the vertical rib of stiffening rib; Stiffening rib inside is provided with the cross rib connecting allotment bearing portion and circular arc support.The utility model improves the non-deformability of stiffening rib, improves the ring stiffness being wound around bellows further, and has saved cost of material.
Description
Technical field
The utility model relates to pipe technology field, is specially a kind of two internal-rib and strengthens winding structure pipe.
Background technique
Along with the increase of urban population number, in the designing requirement medium caliber of buried pipeline in continuous increasing, simultaneously along with the increasing of bore, also need the larger buried degree of depth, the ring stiffness index that these conditions all require tubing to possess more to increase, prevents from occurring the phenomenons such as conquassation in using process.
Existing hollow wound pipe is provided with the stiffening rib of arc on tube wall, although intensity gets a promotion, intensity still can not meet the demands, this is because the stiffening rib of arc adopts hollow structure, and easy stress deformation.If be set to solid, then waste of raw materials is serious, and the link position especially between tube and tube, the most easily becomes tubing point of rupture, have impact on the life-span of tubing greatly.
Summary of the invention
The technical problem that the utility model solves is to provide a kind of two internal-rib to strengthen winding structure pipe, to solve the problem in above-mentioned background technology.
The technical problem that the utility model solves realizes by the following technical solutions:
A kind of two internal-rib strengthens winding structure pipe, comprise body and the profile shapes unit being arranged at described tube wall, described profile shapes unit comprises and the bottom of described tube wall welding one and the stiffening rib being arranged at described two bottom sides edge, described stiffening rib comprises allotment bearing portion, transition part and circular arc support, the upper end of described allotment bearing portion and described circular arc support utilizes described transition part to integrally combine, the lower end of described allotment bearing portion and described circular arc support all links with the bottom of described profile shapes unit and is integrated, and described allotment bearing portion is perpendicular to the bottom of described profile shapes unit,
Described profile shapes unit is helically wound around on described tube wall, and utilizes sol layer to combine between the adjacent straight support of different circle profile shapes unit, forms the vertical rib of described stiffening rib; Described stiffening rib inside is provided with the cross rib connecting described allotment bearing portion and described circular arc support.
In the utility model, described cross rib is vertical with described allotment bearing portion to be arranged.
Owing to adopting above technological scheme, the utility model has following beneficial effect:
Utilize sol layer to combine between allotment bearing portion due to profile shapes unit, form the vertical rib of described stiffening rib, than traditional hollow reinforced rib, when whole body receives radial pressure, good restriction can be played to the distortion of hollow reinforced rib.
Owing to being provided with cross rib in stiffening rib, when hollow reinforced rib is subject to axial pressure, the energy of deformation of cross rib to stiffening rib plays restriction, effectively reduces the distortion possibility of hollow reinforced rib, thus improves the ring stiffness that two internal-rib strengthens winding structure pipe.
In sum, the utility model improves the non-deformability of stiffening rib, improves the ring stiffness being wound around bellows further, and has saved cost of material.

Fig. 2 is the structural representation of the utility model profile shapes unit.
Embodiment
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the utility model further.
See Fig. 1 and Fig. 2, a kind of two internal-rib strengthens winding structure pipe, comprise body 1 and the profile shapes unit 2 being arranged at described body 1 outer wall, described profile shapes unit 2 comprises and the bottom 3 of described body 1 outer wall welding one and the stiffening rib 4 being arranged at dual-side edge, described bottom 3, described stiffening rib 4 comprises allotment bearing portion 5, transition part 6 and circular arc support 7, the upper end of described allotment bearing portion 5 and described circular arc support 7 utilizes described transition part 6 to integrally combine, the lower end of described allotment bearing portion 5 and described circular arc support 7 all links with the bottom 3 of described profile shapes unit 2 and is integrated, and described allotment bearing portion 5 is perpendicular to the bottom 3 of described profile shapes unit 2, described profile shapes unit 2 is helically wound around on described body 1 outer wall, and utilizes sol layer 8 to combine between the adjacent straight support 5 of different circle profile shapes unit 2, forms the vertical rib of described stiffening rib 4, described stiffening rib 4 inside is provided with the cross rib 9 connecting described allotment bearing portion 5 and described circular arc support 7.
In the utility model, described cross rib 9 is vertical with described allotment bearing portion 5 to be arranged.
More than show and describe basic principle of the present utility model and major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
