Description
Technical field
The utility model relates to bridge construction technical fields, connect in particular to a kind of closure of stiff skeleton arch bridge of concrete filled steel tube
Header structure.
Background technique
Arch bridge refers in perpendicular to encircle the bridge as the main supporting member of structure, recently as arch bridge
Development is self-possessed in configuration aspects with mitigating for main target, more next as the arch bridge of main arch ring using steel pipe stiff skeleton structure
It is more.In the installation process of steel pipe stiff skeleton, stiff skeleton closure section generallys use flanged joint or bolting and welding connection,
Bolt-weld joint is to first pass through after bolt temporarily connects alignment to be welded and fixed again.But since the line style of stiff skeleton is by temperature, Suo Li
The influence of equal factors, control difficulty is larger, and the bolts at two ends hole that often will appear closure section is not right in radial direction or circumferential direction
Together, difficulty of construction is caused to increase, it is inconvenient.
Utility model content
The purpose of this utility model seeks to overcome above-mentioned the shortcomings of the prior art, provides that a kind of structure is simple, applies
Work is convenient, improves the stiff skeleton arch bridge of concrete filled steel tube closure joint structure of the axially mounted precision of closure section.
To achieve the above object, the utility model provides a kind of stiff skeleton arch bridge of concrete filled steel tube closure joint structure, including solid
Determine stiff skeleton and closure section stiff skeleton, the fixed stiff skeleton is fixedly connected with the end of closure section stiff skeleton,
It is characterized in that: further including the bushing pipe that the equal inner sleeve in both ends is in fixed stiff skeleton and closure section stiff skeleton, the internal lining pipe
Both ends are slidably matched with fixed stiff skeleton and closure section stiff skeleton.
Further, described internal lining pipe one end outer wall is fixed with the sliding block of one or more radially protrudings, and the other side is set
There is groove.
Further, it is characterised in that: the end of the closure section stiff skeleton or fixed stiff skeleton side is provided with one
A or multiple axial slides；The sliding block is in sliding fit with the sliding chute.
Further, the sliding block radial symmetric is distributed on internal lining pipe, and the sliding slot radial symmetric is arranged in closure section
On stiff skeleton.
Further, tile is cased with outside the closure section stiff skeleton and the fixed stiff skeleton junction.
Further, the single tile is semi-annular shape, and two tile both ends are fixedly connected with.
The beneficial effects of the utility model are: structure is simple, quick construction, the axially mounted precision of closure section ensure that.It is first
First passing through impact sliding block insertion sliding slot makes internal lining pipe inner sleeve in closure section stiff skeleton, lifts to closure section stiff skeleton to solid
Determine first to be finely adjusted at stiff skeleton port, internal lining pipe band groove one end is then inserted by fixed stiffness bone by impact sliding block
In frame, the axially mounted precision of closure section ensure that in this way, and total is simple, quick construction.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model.
Fig. 2 is tile structural schematic diagram.
Fig. 3 is internal lining pipe and steel plate structure schematic diagram.
Each part numbers are as follows in figure: 1- tile；2- internal lining pipe；21- groove；3- sliding block；4- sliding slot；5- closure section stiffness
Skeleton；6- fixes stiff skeleton.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing, convenient for more clearly understanding that this is practical new
Type, but they do not constitute the utility model and limit.
As shown in Figures 1 to 3, a kind of stiff skeleton arch bridge of concrete filled steel tube closure joint structure, including be already installed on master bridge
Fixation stiff skeleton 6 and also uninstalled closure section stiff skeleton 5, stiff skeleton is that more steel pipes are constituted, fixation stiffness bone
Frame 6 is consistent with the diameter of steel tube and wall thickness at 5 both ends of closure section stiff skeleton, and both ends are fixedly connected by welding, above-mentioned
Joint structure further includes internal lining pipe 2, and inner sleeve is distinguished in fixed stiff skeleton 6 and closure section stiff skeleton 5 in 2 both ends of internal lining pipe,
And with fixed stiff skeleton 6 and 5 clearance fit of closure section stiff skeleton.
In above-mentioned technical proposal, internal lining pipe 2 is fixed with radially protruding on the outer wall of 5 side of closure section stiff skeleton
Sliding block 3, closure section stiff skeleton 5 are provided with axial slide 4, sliding block 3 and the equal diameter of sliding slot 4 by the end of fixed 6 side of stiff skeleton
To being symmetrical arranged, sliding block 3 is slidably matched with sliding slot 4；Internal lining pipe 2 is additionally provided with annular groove by fixed 5 side end of stiff skeleton
21.In this way, 2 inner sleeve of internal lining pipe can be made in closure section stiff skeleton 5 and fixed stiffness bone by applying axial force to sliding block 3
In frame 6, enable closure section stiff skeleton 5 and fixed stiff skeleton 6 Accurate align in the axial direction, meets installation accuracy；When
When certain radial missing occur in closure section stiff skeleton 5 and fixed stiff skeleton 6, annular groove 21 is conducive to the insertion of internal lining pipe 2
In fixed stiff skeleton 6.
In above-mentioned technical proposal, it is cased with tile 1 outside closure section stiff skeleton 5 and fixed 6 junction of stiff skeleton, single watt
Pipe 1 is semi-annular shape, and two 1 both ends of tile are welded into whole ring form, and tile 1 is to closure section stiff skeleton 5 and fixed stiffness bone
6 junction of frame is further strengthened and is supported.
Stiff skeleton arch bridge of concrete filled steel tube closure joint structure described in the utility model passes through external force when being joined the two sections of a bridge, etc first
Beating sliding block 3 makes sliding block 3 be inserted into sliding in sliding slot 4, and the whole inner sleeves of internal lining pipe 2, then will closure in closure section stiff skeleton 5
Section stiff skeleton 5 is hoisted to predetermined position, and the position of adjustment closure section stiff skeleton 5 makes itself and fixed 6 end axis of stiff skeleton
To alignment, sliding block 3 is then reversely beaten by external force, and side of the internal lining pipe 2 with groove 21 is made to be inserted into fixed stiff skeleton 6
It is interior, closure section stiff skeleton 5 and the port junction of fixed stiff skeleton 6 are welded and fixed, sliding block 3 is protruded from into closure
The part of section 5 outer wall of stiff skeleton is cut away；Finally by 1 housing of tile of multiple semicircular rings in weld, and weld tile 1
Both ends make two tiles 1, and it is spliced into full circle ring, and the full circle ring of multiple splicings plays assistant reinforcement branch to the junction of closure section
Support effect.
