Description
Technical field
The utility model is related to a kind of form bracing systems, and in particular to a kind of U-shaped abutment form bracing system.
Background technology
Because prestressed simple beam or prestress concrete box girder can give one active soil stress of abutment, transmitted to reduce by beam
The stress to come over, abutment can use U-typed abutment in design.The platform back side of U-shaped abutment is tilted to abutment foundation direction, so as to
Also necessarily slope inwardly in corresponding template, this just increases degree-of-difficulty factor to pass mould.At present, between U-shaped abutment template
Main that pass mould is carried out by the way of split bolt locking, this pass mould mode not enough fastens, and mass concrete construction pair
Form stable requirement is very high, if there is quick-fried mould situation during casting concrete, abutment concrete formation quality certainly will be made
It is influenced into certain.In addition, being completed in abutment template construction, and after casting concrete, do not vibrate for construction personnel flat
Platform, construction personnel vibrate it is not in place, further influence concrete formation quality.
Invention content
In view of the above shortcomings of the prior art, technical problem to be solved in the utility model is：Template stability is poor, holds
Explosive mould influences abutment concrete formation quality, and does not have the platform to vibrate for construction personnel after concreting.
In order to solve the above-mentioned technical problem, the utility model employs following technical solution：
A kind of U-shaped abutment form bracing system, including the abutment template being fixed on abutment foundation, the abutment template packet
Include side form, end mould and back of the body mould；It is characterized in that, it is equipped in abutment template, on abutment foundation outside multiple rows of stretching abutment foundation simultaneously
The embedded bar set along abutment template length direction, more are respectively and fixedly provided on every embedded bar and is used to support each piece of template
And the supporting rod being obliquely installed, the top of every supporting rod are close to form a supporting point on the inside of each template, per 500mm ×
At least there is a supporting point on the template area of 500mm；One is respectively and fixedly provided with through corresponding in the support end of every supporting rod
Template simultaneously stretches out the screw outside template, be all provided on every screw, on the outside of template there are one with screw is matched holds out against nut.
Template is supported by supporting rod, meanwhile, by screw and the cooperation for holding out against nut, template is held out against from outside, and then
Both direction is all held out against with external force inside and outside every piece of template, more firm, is not in quick-fried mould phenomenon.In addition, inside template
Embedded bar and supporting rod pour together, so as to increase some internal reinforcing bars on the basis of plain concrete, to a certain extent
The intensity for strengthening bridge abutment structure can be played.
Further, by being welded and fixed between supporting rod and embedded bar, between screw and supporting rod, and screw with
Weld length between supporting rod is at least 10CM, throat thickness 2-5mm.The mode of welding connects reinforcing bar, and bonding strength is high,
And weld length is longer, the bonding strength between screw and supporting rod is also better.
Further, it wherein two rows of embedded bars stretch out abutment template top, is equipped on this two rows of embedded bar more
End to end plank is opened, the plank forms an occasional passage for construction personnel's walking；Often between row's embedded bar etc.
Away from setting, the spacing between adjacent embedded bar is 1.4-1.6m.By embedded bar, and on reinforcing bar be laid with plank mode
An occasional passage to pass through for construction personnel is formd, so as to be provided for construction personnel's vibrating during casting concrete
Operating platform.
Compared with prior art, the U-shaped abutment form bracing system that the utility model obtains has the following advantages that：
1st, it is additionally arranged they sup-port template, and after welding screw in supporting rod end, using holding out against nut check template,
This fixed form extremely fastens, and is not in the situation of quick-fried mould, improves the stability of template, so as to ensure the molding of abutment
Quality.
2nd, by embedded bar, and on reinforcing bar be laid with plank mode form one for construction personnel pass through it is interim
Channel, so as to provide operating platform for construction personnel's vibrating during casting concrete.
3rd, the embedded bar inside template and supporting rod pour together, so as to be increased on the basis of plain concrete
Internal reinforcing bar can play the intensity for strengthening bridge abutment structure to a certain extent.

Specific embodiment
The utility model is further illustrated with reference to the accompanying drawings and examples.
Embodiment：
As shown in figs 1 to 6, U-shaped abutment form bracing system provided in this embodiment, including being fixed on abutment foundation 1
Abutment template 2, the abutment template 2 include side form, end mould and the back of the body mould, the end mould and the back of the body mould with respect to thirty years of age, side form is placed in
It holds between mould and back of the body mould；It is outer and along abutment template 2 that multiple rows of stretching abutment foundation 1 is equipped in the abutment template 2, on abutment foundation 1
Length direction setting embedded bar 3, be respectively and fixedly provided on every embedded bar 3 more be used to support each piece of template and tilt set
The supporting rod 4 put, the top of every supporting rod 4 are close to form a supporting point on the inside of each template, the mould per 500mm × 500mm
At least there is a supporting point in plate suqare；One is respectively and fixedly provided with through corresponding template in the support end of every supporting rod 4 and is stretched
Go out the screw 5 outside template, be all provided on every screw 5, on the outside of template there are one with screw 5 is matched holds out against nut 6.This reality
It applies the supporting rod 4 in example, embedded bar 3 to form using discarded reinforcement fabrication, waste material can be recycled, simultaneously, moreover it is possible to reduce
Construction cost.And after supporting rod 4 is obliquely installed, a very firm triangle is formed between supporting rod 4 and abutment foundation 1
Shape is provided with holds out against each template conducive to supporting rod 4 in this way, and very firm.As shown in figure 5, in specific implementation, in order to
So that the bonding strength between template is more firm, quick-fried mould phenomenon is further prevented, more are additionally provided between back of the body mould and side form
For tensing the Screw arbor with nut at both-ends of back of the body mould and side form.
As shown in Figure 5, Figure 6, between supporting rod 4 and abutment foundation 1 shape in an angle, supporting rod 4 and embedded bar 3 it
Between, between screw 5 and supporting rod 4 by being welded and fixed, and the weld length between screw 5 and supporting rod 4 is at least 10CM,
Throat thickness is 2-5mm.In welding, by a discarded reinforcement welding between screw 5 and supporting rod 4, can be effectively ensured in this way
Its throat thickness increases the firmness of pad.
As shown in Fig. 2, wherein two rows of embedded bars 3 in embedded bar 3 stretch out 2 top of abutment template, it is two rows of pre- at this
It buries and multiple end to end planks 7 is equipped on reinforcing bar 3, the plank 7 forms one for the interim logical of construction personnel's walking
Road 8；3 spaced set of embedded bar is often arranged, the spacing between adjacent embedded bar 3 is 1.5m or so, specially 1.5m.
Finally it should be noted that above example is merely intended for describing the technical solutions of the present application, but not for limiting the present application technology
Scheme, although applicant is described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the art
It should be appreciated that those are modified or replaced equivalently the technical solution of the utility model, without departing from the technical program
Objective and range should all cover in the right of the utility model.
