Description
Technical field
The utility model belongs to the technical field that science of bridge building prefabricated box -beam component uses utilizing prestressing force post tensioning method construction, specifically
It is related to a kind of prefabricated case beam bellows coordinate location device.
Background technique
Post-tensioned precast box girder is stringenter to the pipeline location requirement of bellows, and whether pipeline location accurately directly affects
Whether the tension stress to post-tensioned precast box girder is able to satisfy design requirement, is related to the service life of box beam.It is constructing at present
In the process to the control of pipeline location be by designing institute to pipeline coordinate realize, i.e., along beam length given in design drawing
The X-coordinate in direction and Y-coordinate relative to box beam bottom plate.
The coordinate setting process sequence of existing bellows is, first mounting base, web reinforcement welding bellows groined type again
Positioning bar finally wears bellows.
The prior art the disadvantage is that: the pipeline coordinate (position i.e. relative to box beam bottom plate) of bellows is to pass through groined type
Positioning bar controls, and such method is carried out after bottom web reinforcement is installed, difficulty of construction and grid deviation are larger,
Prior art process velocity is slow.
Utility model content
For the above-mentioned technical problems in the prior art, the utility model proposes a kind of prefabricated case beam bellows seats
Positioning device is marked, design rationally, overcomes the deficiencies in the prior art, has good effect.
To achieve the goals above, the utility model adopts the following technical solution:
A kind of prefabricated case beam bellows coordinate location device, including pedestal are provided with X, Y coordinates axis on pedestal, sit in X, Y
It is welded with round steel or angle steel on parameter, is placed with web reinforcement from X, Y-axis intersection point in X, Y plane, wave is located on pedestal
The duct position of line pipe, be welded with around the duct position of bellows as bellows spacer bar position anchor point i.e.
Spacer bar head.
Preferably, pedestal is made of aluminum alloy plate materials or steel plate.
Preferably, spacer bar head can be replaced by same specification bolt.
Advantageous effects brought by the utility model:
The utility model is segmented a setting-out according to ripple pipeline type and welds sizing, for reusing, avoids every
Secondary single-piece setting-out improves production efficiency to save manually.
Position of the bellows in web reinforcement can be accurately found out by the foundation of pedestal coordinate system；Pass through control simultaneously
Point device is avoided in welding bellows spacer bar because of deviation caused by human factor；Secondly, by existing post-processing
Bellows spacer bar (after web reinforcement installation) is changed to first machining bellows positioning bar, avoids other Reinforcing Steel Bar On Wave line pipes
The interference of positioning bar welding.
Utility model device can the factorial production, control point can be fabricated to the dress of adjustable Y-coordinate in Y direction
It sets；Substantially increase the accuracy of bellows positioning bar installation effectiveness and corrugated pipe pipeline position.
Detailed description of the invention
Fig. 1 is the reference axis schematic diagram established on pedestal.
Fig. 2 is that the web reinforcement processed puts schematic diagram from X, Y-axis intersection point in X, Y plane.
Fig. 3 for according to drawing the schematic diagram of bellows duct position is made to the Y-coordinate of bellows.
Fig. 4 is the positioning device schematic diagram of the utility model bellows.
Wherein: 1- pedestal；2- spacer bar head.
Specific embodiment
With reference to the accompanying drawing and specific embodiment is described in further detail the utility model:
Embodiment 1:
A kind of prefabricated case beam bellows coordinate location device is provided with X, Y seat as shown in figure 4, including pedestal 1 on pedestal 1
Parameter is welded with round steel or angle steel on X, Y coordinates axis, web reinforcement is placed with from X, Y-axis intersection point in X, Y plane, in platform
The duct position of bellows is located on seat 1, is welded with around the duct position of bellows as bellows spacer bar
The anchor point of position, that is, spacer bar head 2.
Pedestal 1 is made of aluminum alloy plate materials or steel plate.
Spacer bar head can be replaced by same specification bolt.
Embodiment 2:
On the basis of the above embodiments, the utility model is also mentioned that a kind of prefabricated case beam bellows coordinate location method,
Include the following steps:
Step 1: pedestal production；Specifically comprise the following steps:
Step 1.1: establishing coordinate system
X, Y coordinates axis is drawn on pedestal, and round steel or angle steel are welded on X, Y coordinates axis；As shown in Figure 1；
Step 1.2: coordinate setting；
The web reinforcement processed is put in X, Y plane from X, Y-axis intersection point；As shown in Figure 2；
X, the y-coordinate of the bellows given according to drawing position the duct position of bellow respectively；As shown in Figure 3；
Step 2: welding bellows coordinate control point；
Anchor point of the spacer bar head as bellows spacer bar position is welded around the duct position of bellows,
Spacer bar head line, which is formed by outside rectangle, is cut in bellows；
Step 3: repeating step 1-2, the bellows coordinate control point in remaining web reinforcement is made on pedestal；
Step 4: the web reinforcement of bellows spacer bar will have been welded, installed to steel bar framework of box beam；
Step 5: bellows being passed through into the web reinforcement on steel bar framework of box beam, that is, completes the accurate positionin of bellows.
Certainly, the above description is not intended to limit the present invention, and the utility model is also not limited to the example above,
The variations, modifications, additions or substitutions that those skilled in the art are made in the essential scope of the utility model, are also answered
Belong to the protection scope of the utility model.
