Description
[technical field]
The utility model belongs to gas pipeline mounting technique field, more particularly to a kind of bridge tube bracket with long service life
Structure.
[background technique]
Gas pipeline, which crosses the river, at present generallys use along the overhead mode of bridge bracket, and pipe material is usually steel pipe, and is propped up
The bracket for supportting bridge tube is also mostly steel bracket, as the accumulation and steel pipe itself of bridge tube two sides soil property sedimentation are expanded with heat and contract with cold,
The position that steel pipe is contacted with bracket can lead to pipe corrosion aggravation herein due to friction, combustion gas can be caused to let out due to corrosion when serious
Leakage.
Therefore, it is necessary to provide the new bridge tube supporting structure with long service life of one kind to solve the above problems.
[utility model content]
The main purpose of the utility model is to provide a kind of bridge tube supporting structure with long service life, reduce steel pipe with
The frictional force of support has delayed the corrosion of steel pipe, improves the service life of steel pipe.
The utility model is achieved through the following technical solutions above-mentioned purpose: a kind of bridge tube supporting structure with long service life,
It include bottom plate, be welded on the bottom plate and formed by bottom support channel steel, Left-side support channel steel and Right side support channel steel
U-shaped support construction, one end is welded on bottom support channel steel and the other end is welded on the Left-side support channel steel
First bearing diagonal, one end are welded on the bottom support channel steel and the other end is welded on second on the Right side support channel steel
It bearing diagonal, the first PE casing being set on first bearing diagonal surface and is set on second bearing diagonal surface
The 2nd PE casing, the first PE casing and the first bearing diagonal clearance fit, the 2nd PE casing and described second
Bearing diagonal clearance fit.
Further, the angle of first bearing diagonal and bottom support channel steel is 45 °~65 °.
Further, the angle of first bearing diagonal and bottom support channel steel is 45 ° or 60 °.
Further, the angle of second bearing diagonal and bottom support channel steel is 45 °~65 °.
Further, the angle of second bearing diagonal and bottom support channel steel is 45 °, 60 °.
Further, the first PE casing and the 2nd PE casing with a thickness of 10mm or more.
Further, the both ends of the bottom plate are connect by chemical anchor bolts with concrete pier.
Compared with prior art, a kind of beneficial effect of bridge tube supporting structure with long service life of the utility model is:
1) changing the way of contact of original support entire surface and bridge tube, the diagonal brace of two sides can significantly reduce contact surface, thus
Delay corrosion caused by due to bracket and steel pipe contact；2) the flexible PE sleeve that two sides diagonal brace installs additional is longitudinally compensated in bridge tube
When, thus it is possible to vary sliding friction is rolling friction, reduces compensation resistance, improves compensation effect, meanwhile, reduce steel pipe and support
Frictional force and resulting corrosion, guarantee the operational safety of bridge tube.

[specific embodiment]
Embodiment:
Fig. 1 is please referred to, the present embodiment is bridge tube supporting structure 100 with long service life comprising bottom plate 1 is welded on bottom
U-shaped support construction that is on plate 1 and being formed by bottom support channel steel 2, Left-side support channel steel 3 and Right side support channel steel 4, one end are welded
It connects the first bearing diagonal 5, one end that on bottom support channel steel 2 and the other end is welded on Left-side support channel steel 3 and is welded on bottom
Support channel steel 2 on and the other end be welded on Right side support channel steel 4 the second bearing diagonal 6, be set on 5 surface of the first bearing diagonal
The first PE casing 7 and the 2nd PE casing 8 that is set on 6 surface of the second bearing diagonal.
The angle of first bearing diagonal 5 and bottom support channel steel 2 is 45 °~65 °, preferably 45 °, 60 °.Second bearing diagonal
6 with bottom support channel steel 2 angle be 45 °~65 °, preferably 45 °, 60 °.
First PE casing 7 and the 2nd PE casing 8 with a thickness of 10mm or more.5 gap of first PE casing 7 and the first bearing diagonal
Cooperation.6 clearance fit of 2nd PE casing 8 and the second bearing diagonal.
The both ends of bottom plate 1 are connect by chemical anchor bolts 9 with concrete pier.
The exposed surface of the U-shaped support construction is coated with preservative.
Stress main body of the U-shaped support construction as support, is mounted on the bracket of bridge side and is fixed；Bridge tube is placed
On the first bearing diagonal 5 and the second bearing diagonal 6, PE pipe is directly contacted with bridge tube, and passes through the rotation compensation bridge tube of PE casing
Axial deformation；Simultaneously as the presence of bearing diagonal can stop bridge tube radially deformation, control bridge tube can only axially be stretched
Contracting.
The beneficial effect of the present embodiment bridge tube supporting structure 100 with long service life is: 1) it is entire to change original support
The diagonal brace of the way of contact in face and bridge tube, two sides can significantly reduce contact surface, to delay to connect because of bracket and steel pipe
Touching and caused by corrode；2) the flexible PE sleeve that two sides diagonal brace installs additional is when bridge tube longitudinally compensates, thus it is possible to vary sliding rubs
Wiping is rolling friction, reduces compensation resistance, improves compensation effect, meanwhile, reduce the frictional force of steel pipe and support, and thus
The corrosion of generation guarantees the operational safety of bridge tube.
Above-described is only some embodiments of the utility model.For those of ordinary skill in the art,
Without departing from the concept of the present invention, various modifications and improvements can be made, these belong to practical
Novel protection scope.
