Description
Technical field
The invention belongs to steel case Construction of Arch Bridges construction fields, and in particular to a kind of fast aligning side of steel case arch bridge anchor tube
Method.
Background technology
With the development of Urban Bridge Construction, more landscape moulding steel arch bridges are more and more, most of project construction side
The installation sequencing of case is installation arch section after first installing bridge floor beam.Main arch is hyperbolic irregular box cell structure, and arch rib arch is vertical
Face projection line is parabola, and anchor cable not instead of vertical connection is connected with angle tilt.Corresponding band anchor tube（Anchor tube includes bridge
Face anchor tube 3 and arch section anchor tube 4）Arch Duan Ruo error is installed, it is wrong to will result in anchor cable installation, the angle of tensioning, or even meeting
Lead to have the service life for rubbing and reducing anchor cable between anchor cable and anchor tube, it is therefore desirable to a kind of quick, simple and direct, accurate positioning
Installation method, meaning ensure the accuracy of anchor tube anchor cable installation.In the conventional method of anchor tube location and installation, arch section lifting is in place
Afterwards, it during high-altitude is looked in installation personnel to arch section, is adjusted using plumb line and floor projection, this method increases installation personnel
High-altitude construction risk, increase lifting machine machine-team and construction time.
Invention content
In view of the above technical problems, the purpose of the present invention is to provide a kind of fast aligning method of steel case arch bridge anchor tube,
This method can it is quick, simple and direct, accurately to anchor tube carry out fast aligning installation, reduce security risk, reduce construction cost,
Shorten the construction period.
To achieve the above object, the technical solution used in the present invention is：
A kind of fast aligning method of steel case arch bridge anchor tube, it is characterised in that include the following steps：
Step 1: in first looking for bridge floor anchor tube and arch section anchor tube, finds bridge floor anchor tube and encircle the axis of section anchor tube；Again in bridge
A crystal rope is installed on the axis of face anchor tube and arch section anchor tube；
Step 2: after the installation of bridge floor anchor tube, a holder is placed above bridge floor anchor tube；A laser is placed on holder again
Level, and adjust laser level and make the laser that laser level is sent out and the crystal rope weight on bridge floor anchor tube axis
It closes；
Step 3: installation lifting arch section, and adjust the position of arch section anchor tube so that crystal rope and laser on arch section anchor tube axis
The laser that level is sent out overlaps, and completes the fast aligning of anchor tube.
First in the both ends of anchor tube two crystal ropes diametrically arranged crosswise, the intersection point, that is, center of circle in step 1；One is taken again
Crystal rope, both ends are separately connected the intersection point of the two crystal ropes in anchor tube both ends.
The holder includes a panel and four supporting legs, collectively forms desk type, it is big to offer diameter on the panel
In the round sight vane of anchor tube diameter；In use, mount is on bridge floor beam, sight vane and bridge floor anchor tube arranged concentric.
Beneficial effects of the present invention are：
1, this method can it is quick, simple and direct, location and installation accurately is carried out to anchor tube, reduce security risk, reduce and be constructed into
Originally, the construction period is shortened.
2, this method utilizes the radiating laser beams of laser level, the registration of remote observation laser beam and crystal rope.
3, this method utilizes the stronger crystal rope of translucency, is preferably penetrated convenient for the laser beam of laser level.

Specific implementation mode
For a better understanding of the present invention, technical scheme of the present invention is done further with reference to embodiment and attached drawing
Explanation（As shown in figures 1 to 6）.
A kind of fast aligning method of steel case arch bridge anchor tube, includes the following steps：
Step 1: first to bridge floor anchor tube 3 and arch section anchor tube 4（Bridge floor anchor tube 3 and arch section anchor tube 4 are referred to as anchor tube）In being looked for,
It finds bridge floor anchor tube 3 and encircles the axis of section anchor tube 4；A crystal rope is installed on the axis of bridge floor anchor tube 3 and arch section anchor tube 4 again
8；
Step 2: after the installation of bridge floor anchor tube 3, a holder 6 is placed above bridge floor anchor tube 3；Place one on the frame 6 again
Laser level 5, and adjust laser level 5（Telescopic outrigger 12）So that laser 7 and bridge floor that laser level 5 is sent out
Crystal rope 8 on 3 axis of anchor tube overlaps（With this so that the angle of laser level 2 is consistent with the angle of Cheng Qiaohou anchor cables）；
Step 3: installation lifting arch section 2, and adjust the position of arch section anchor tube 4 so that crystal rope 8 on 4 axis of arch section anchor tube with
The laser 7 that laser level 5 is sent out overlaps, and completes the fast aligning of anchor tube.
First in the both ends of anchor tube two crystal ropes 8 diametrically arranged crosswise, the intersection point, that is, center of circle in step 1；One is taken again
Crystal rope 8, both ends are separately connected the intersection point of the two crystal ropes 8 in anchor tube both ends.
The holder 6 includes a panel 9 and four supporting legs 10, collectively forms desk type, is offered on the panel 9 straight
Diameter is more than the round sight vane 11 of anchor tube diameter；In use, holder 6 is placed on bridge floor beam 1, sight vane 11 and bridge floor anchor tube 3
Arranged concentric.It is fixed with magnetite between telescopic outrigger 12 and panel 9.
The making of the holder 6：Square steel plate（t=10mm）As panel 9, and sight vane 11 is opened up on panel 9, have an X-rayed
11 diameter of hole is more than anchor tube diameter 50mm, angle steel（L40）As supporting leg 10, height is slightly above anchor tube.
Described above is only the Application Example of the present invention, cannot limit the right model of the present invention with this certainly
It encloses, therefore according to equivalence changes made by scope of the present invention patent, still belongs to protection scope of the present invention.
