Description
Technical field
The present invention relates to arch bridges construction field, specifically a kind of support knot for being used to support bowstring arch bridge main structure
Structure.
Background technique
Bowstring arch bridge is as a member in arch bridge family, the general features with arch bridge, and has the exclusive feature of itself.It
It is the bridge type of the advantages of integrating arch and beam a kind of, it combines arch with two kinds of basic structure forms of beam, holds jointly
By load, gives full play to beam and born, made with pull rod by curved, arch compression structural behaviour and compound action, the horizontal thrust of arch abutment
Arch abutment support does not generate horizontal thrust.Arch is coupled between string with the hinged vertical bar in both ends.Also it can be replaced with brace straight
Bar becomes Nielsen style.Be statically indeterminate system inside this arch bridge, it is external then be static determinacy, therefore to pier differential settlement without
It influences.Thrust is can be mainly divided into from structure and without two kinds of combined systems of thrust.
But the steel construction of bowstring arch bridge by itself it is abnormally-structured influenced, in hoisting process, steel construction stress condition
Complexity, unstable factor are more, it is difficult to stablize installation, be easy to happen safety accident.
Summary of the invention
In order to overcome the deficiencies of the prior art, the present invention provides a kind of support knots for being used to support bowstring arch bridge main structure
Structure is supported the main structure of bowstring arch bridge in bowstring arch bridge work progress, with the stability of retainer body structure, mentions
The efficiency and precision of height construction.
Technical solution used by the present invention solves the above problems is: a kind of branch being used to support bowstring arch bridge main structure
Support structure, including the support frame on the outside of bridge pier and several settings is arranged on the support frame and for bowstring arch bridge main body knot
The position limiting structure that structure is supported.
Further, in order to preferably realize the present invention, the support frame is arranged on the outside of bridge pier in a ring.
Further, in order to preferably realize the present invention, the bottom of the support frame is provided with carrying steel plate.
Further, in order to preferably realize the present invention, the position limiting structure rotational installation is on the support frame, described
Be provided on support frame for position limiting structure into line-locked locking structure.
Beneficial effect acquired by this programme is:
This programme is using the support frame being arranged on the outside of bridge pier as load-carrying construction, convenient for making the main structure of bowstring arch bridge
Near lifting to installation position, and convenient for being positioned to main structure, in construction, reduces and adjust the dynamic of main structure position
Make, be conducive to the efficiency for improving positioning, installation, support frame is arranged on the outside of bridge pier, can be made using the cushion cap of support bridge pier
For the installation foundation of support frame, avoids support frame stress from settling and influence the stability of main structure.
Detailed description of the invention
Fig. 1 uses schematic diagram for this programme；
Fig. 2 is the position view for carrying steel plate.
Wherein: 1- support frame, 2- position limiting structure, 3- carry steel plate, 4- bridge pier, 5- main structure, 6- cushion cap.
Specific embodiment
Below with reference to examples and drawings, the present invention is described in further detail, but embodiments of the present invention are not
It is limited to this.
As shown in Figure 1, in the present embodiment, a kind of support construction being used to support bowstring arch bridge main structure, including setting
The support frame 1 in the outside of bridge pier 4 and several be arranged on support frame 1 and for being supported to bowstring arch bridge main structure
Position limiting structure 2.
When construction, support frame 1 is mounted on to the outside of bridge pier 4, support frame 1 is higher than bridge pier 4.Extremely by the lifting of main structure 5
4 top of bridge pier, the upper surface of bridge pier 4 are provided with the locating slot for being positioned to main structure 5, utilize 4 outside of bridge pier
Position limiting structure 2 on support frame 1 is supported main structure 5, can play the role of auxiliary positioning to main structure 5, and
And main structure 5 is supported to keep its stable structure, due to the positioning action of main structure 5, adjustment master can be reduced
The difficulty of body structure 5 and required time are conducive to improve construction efficiency.
The upper surface of support frame 1 can install horizontal steel plate, in this, as the installation foundation of position limiting structure 2, be conducive to
Enhance the stability and bearing capacity of position limiting structure 2.
Support frame 1 using one of steel pipe, angle steel, channel steel or it is a variety of be combined, overlap to form.
Bridge pier 4 is supported by cushion cap 6, and the cross-sectional area of cushion cap 6 is greater than the cross-sectional area of bridge pier 4, and support frame 1 is arranged
In 4 outside of bridge pier, support can be played the role of to support frame 1 using cushion cap 6,1 stress of support frame is avoided to settle and influence master
The stability of body structure 5.
After main structure 5 installs, support frame 1 is removed, it, will not shadow since support frame 1 is not contacted with bridge pier
Ring the integrality of bridge pier 4.
For the ease of position limiting structure 2 is adjusted, it is rotatably installed in position limiting structure 2 on support frame 1, corresponding needs
Position limiting structure 2 is locked to keep its stability using locking structure.
Position limiting structure 2 can be also attached by the way of welding with support frame 1, can guarantee position limiting structure 2 with this
It will not move in the construction process.
In order to increase the rigidity and stability of support frame 1 itself, support frame 1 is set on the outside of bridge pier in a ring.Branch
Whole support 1 is in cuboid-type, and the limit being supported from multiple directions to main structure 5 can be arranged on supporter 1 with this
Bit architecture 2, to enhance the stability of main structure 5.
As shown in Fig. 2, the bottom of the support frame 1 is provided with carrying steel plate 3.Branch can be enhanced using carrying steel plate 3
The stability of support 1.
Support frame 1 and carrying steel plate 3 are welded, support frame 1 can be increased and carry the bonding strength of steel plate 3, be conducive to
Support frame 1 is prevented to be subjected to displacement.
Support frame 1 can be also attached with carrying steel plate 3 by the way of being detachably connected, such as be connected using bolt
It connects, is detachably connected support frame 1 with carrying steel plate 3, can facilitate after the completion of main structure 5 is constructed and remove support frame 1
And avoid damage to lower part cushion cap 6.
The inside of cushion cap 6 can be arranged in construction bearing platform 6 in the carrying steel plate 3, with enhancing carrying steel plate 3 with
The bonding strength of cushion cap 6 avoids support frame 1 from there is the risk toppled to be conducive to improve the stability of carrying steel plate 3.
In the present embodiment, other contents not described are same as the previously described embodiments, therefore do not repeat.
It is above-described, it is only presently preferred embodiments of the present invention, is not intended to limit the present invention in any form,
According to the technical essence of the invention, within the spirit and principles in the present invention, to the above embodiments any simply to repair
Change, equivalent replacement and improvement etc., fall within the scope of protection of the technical scheme of the present invention within.
