Abstract
The present invention is a kind of bridge coping or binder shuttering supporting adjusting means and application.Sand bucket and concrete bucket are respectively prepared using the steel pipe of two kinds of different-diameters, sand bucket is as lower barrel support, concrete bucket is positioned in sand bucket as upper barrel support and forms support meanss, and sand bucket diameter is more than concrete bucket diameter, and elevation regulation is carried out by adjusting the sand amount in sand bucket.The advantages below of the supporting and regulating device tool of the present invention：It is simple in construction, it is easy to make, cost is low；It is in light weight, installation（Remove）It is convenient；Reliable and stable, security risk is small.
Description
Technical field
The invention belongs to technical field of bridge engineering, and in particular to one kind is using punching rod iron method cast-in-situ bridge bent cap or is
The supporting and regulating device of template and application during beam.
Background technology
At present, when using punching rod iron method cast-in-situ bridge bent cap or binder, the elevation regulation to template is mainly direct
Adjusted using steel ox pin or be adjusted to form support system using jack is placed again on steel ox pin.Directly adjusted using steel ox pin
For section because ox pin is heavy, regulation is difficult, and elevation is difficult to control；Although being adjusted using jack, regulation is laborsaving, and elevation is easily controllable,
But equipment is heavier（100T jack about 150kg）, hanging device need to be used, jacking equipment cost and mounting cost are higher, and with
The top small stability of steel main beam contact area is poor, sedimentation suddenly may occur because of draining very during especially with hydraulic jack
To serious accident occurs, larger security risk be present.
The content of the invention
It is an object of the invention to provide it is a kind of be advantageous to use punching rod iron method cast-in-situ bridge bent cap or binder when template
Supporting and regulating device and application, reach control cost, be easy to the requirements such as elevation is adjusted, stability is good, security risk is small.
The technical scheme is that：A kind of bridge coping or binder shuttering supporting adjusting means is straight using two kinds of differences
Sand bucket and concrete bucket is respectively prepared in the steel pipe in footpath, and sand bucket is positioned over sand as lower barrel support, concrete bucket as upper barrel support
Support meanss are formed in bucket, sand bucket diameter is more than concrete bucket diameter, and elevation regulation is carried out by adjusting the sand amount in sand bucket.
Bucket steel plate is arranged below in described sand bucket.
Described sand bucket, which is provided with, to be drawn sand hole and draws sand hole baffle plate.
Bucket steel plate on one is provided with above described concrete bucket.
Described bridge coping or the application process of binder shuttering supporting adjusting means：Punching rod iron and steel ox are first installed
Pin, by bent cap or binder template elevation is counter pushes away, and branch is calculated after reducing template, secondary beam, I-steel girder Thickness ness data
Support the elevation of top surface of adjusting means, and altitude traverse marked on pier stud, to supporting and regulating device under pour into sand in bucket, by multiple
After crest level is controlled in adjustment, I-steel girder is installed, and I-steel girder is strained and fixed in time with pull bar and formed in pier stud
Stable system, secondary beam, template are finally installed.
The advantages below of the supporting and regulating device tool of the present invention：It is simple in construction, it is easy to make, cost is low；It is in light weight, installation
（Remove）It is convenient；Reliable and stable, security risk is small.

Embodiment
As shown in figure 1, the supporting and regulating device of the present invention is respectively prepared sand bucket using the steel pipe of two kinds of different-diameters and mixed
Native bucket is coagulated, sand bucket is positioned in sand bucket as upper barrel support as lower barrel support, concrete bucket and forms support meanss, sand bucket diameter
More than concrete bucket diameter, elevation regulation is carried out by adjusting the sand amount in sand bucket.
Described sand bucket is made up of sand loading 5 in lower bucket steel pipe 2, and bucket steel plate 1 is arranged below in sand bucket.On described sand bucket
Sand hole 4 and sand hole baffle plate 3 is drawn provided with drawing.
Described concrete bucket is made up of upper 7 built-in concrete eight of bucket steel pipe, and bucket steel plate on one is provided with above concrete bucket
6。
Upper and lower bucket steel plate 1,6 is made using thickness δ=10mm steel plates, and size is 250 × 250mm, and the lower diameter D of bucket steel pipe 2=
150mm, the upper diameter D=120mm of bucket steel pipe 7, bucket height are 200mm, and bucket is with base steel plate using welding；Irrigated in upper bucket steel pipe
Full C20 concrete eights；Logical sand-passing amount regulation elevation；Sand bucket sets 50 × 50mm's to draw sand hole 4, and baffle plate 3 is opened when form removal, is drawn
Go out sand in bucket, bucket height in reduction.
As shown in Fig. 2 in whole support system, punching rod iron 10 and steel ox pin 11 are first installed.Pass through bent cap（Binder）
16 floor elevations are counter to be pushed away, and reduces the relevant thickness such as template thickness 15, secondary beam 14, I-steel girder 12（Highly）Calculated after data
The elevation of top surface of supporting and regulating device 9, and altitude traverse is marked on pier stud 17, to supporting and regulating device under pour into sand in bucket, lead to
Cross after repeatedly crest level is controlled in adjustment, installation I-steel girder 12, and with pull bar 13 in time tensed I-steel girder 12 solid
Stable system is formed due to pier stud 17, the follow-up works such as secondary beam, template are finally installed.
General principle, principal character and the advantages of the present invention of the present invention has been shown and described above.The technology of the industry
Personnel are it should be appreciated that the present invention is not limited to the above embodiments, and the simply explanation described in above-described embodiment and specification is originally
