Description
Technical field
It the utility model is related to a kind of bridge pier shaft model sheetinstallat positioner, more specifically to a kind of bridge pier shaft
Model sheetinstallat positioner, belong to bridge substructure technical field of construction.
Background technology
At present, railroad bridge, highway bridge, room are built in load-bearing pillar and other pier shaft engineerings, frequently with big punching block of shaping
Plate is constructed.But in pier body formwork work progress, because formwork rigidity and precision are not high enough, frequently result in model sheetinstallat position
Put and shift, can not pass through so that template is checked and accepted, it is impossible to carry out concrete construction, and then be delayed construction speed.
The content of the invention
The purpose of this utility model is for frequently resulting in model sheetinstallat during existing bridge pier shaft model sheetinstallat
Position shifts, is delayed the problems such as construction speed, there is provided a kind of bridge pier shaft model sheetinstallat positioner.
To achieve the above object, technical solution of the present utility model is：A kind of bridge pier shaft model sheetinstallat positioning dress
Put, the straight line on every layer of pier body formwork top with being separately installed with retention bar at circular arc interface point, described retention bar one end with
Pier body formwork is connected, and is provided with positioning hole on retention bar, the positioning hole on the corresponding retention bar of each layer pier body formwork
With pier bottom setting-out mark point on a vertical line.
The a diameter of 20mm of described positioning hole.
Compared with prior art, the beneficial effects of the utility model are：
1st, the utility model is novel, simple in construction, economic and practical, is easy to manipulate.
2nd, the utility model is separately installed with retention bar at the straight line and circular arc interface point on every layer of pier body formwork top, uses
In realizing the control to pier body formwork position, the problem of position shifts in pier body formwork installation process is avoided.
Brief description of the drawings
Fig. 1 is the utility model structure diagram.
Fig. 2 is the utility model horizontal layout schematic diagram.
Fig. 3 is retention bar structural representation in the utility model.
In figure, pier body formwork 1, retention bar 2, vertical line 3, vertical 4 are hung, positioning hole 5.
Embodiment
The utility model is described in further detail below in conjunction with brief description of the drawings and embodiment.
Referring to Fig. 1 to Fig. 3, a kind of bridge pier shaft model sheetinstallat positioner, the straight line and circular arc that every layer of pier body formwork 1 pushes up
Retention bar 2 is separately installed with interface point, described one end of retention bar 2 is connected with pier body formwork 1；Generally use is welded
Or other mechanical connections so that firm and reliable connection.Positioning hole 5 is provided with retention bar 2, each layer pier body formwork 1 is corresponding
Retention bar 2 on positioning hole 5 with pier bottom setting-out mark point on a vertical line.Retention bar 2 generally selects channel-section steel,
Retention bar 2 is identical with the rigidity of pier body formwork 1.
Referring to Fig. 1 to Fig. 3, the design of the length combination pier body formwork 1 of retention bar 2 considers：For no slope than straight slope pier,
All length of retention bar 2 are 1 outer 50cm of stretching pier body formwork or so；For have slope than change slope pier, bottom pier shaft mould
For the length of retention bar 2 of plate 1 to stretch out 1 outer 50cm of pier body formwork or so, the length of retention bar 2 of other layers of pier body formwork 1 should
Extended out when according to corresponding segmental height, be specially：L=L1+ hi, wherein L are the length of retention bar 2, L1For bottom pier
The length of retention bar 2 of body template 1, H be pier bottom to the height of the position of retention bar 2, i is slope ratio.
Referring to Fig. 3, described 5 a diameter of 20mm of positioning hole.
Referring to Fig. 1 to Fig. 3, the utility model is by the outside of pier body formwork 1 installation retention bar 2, then with hanging vertical line 3
Mode to pier body formwork 1 installation be controlled.Specifically during the installation of pier body formwork 1, vertical line 3 is set to pass through each layer
Positioning hole 5 on the corresponding retention bar 2 of pier body formwork 1, make the bottom of vertical line 3 hangs vertical 4 finger in corresponding pier bottom setting-out
In mark point, the relative position of observation vertical line 3 and all positioning holes 5, if vertical line 3 is pacified without by the side of positioning hole 5
The template 1 of dress meets the requirements；If vertical line is close to the side of positioning hole 5, the template 1 installed is undesirable, it is necessary to adjust,
Whether met the requirements it is achieved thereby that judging that pier body formwork 1 is installed.The light such as laser pen electricity can be used by hanging the method for vertical line 3 herein
Sub- equipment replaces.
It may be noted that during the recycling of this positioner, after pier body formwork 1 is removed, it should check that positioning is horizontal in time
Whether bar 2 deforms；Retention bar 2 is checked before installation, avoids the change of the positioner caused by personal reason or accident
Shape, damage.
Meanwhile the applicant has found by studying, it is fine that this retention bar 2 is used for the installation effect of pier body formwork 1.Such as apply
Work field application is proper, and the later stage can directly save pier body formwork 1 and check process.
Above content is to combine specific preferred embodiment further detailed description of the utility model, it is impossible to
Assert that specific implementation of the present utility model is confined to these explanations.For the ordinary skill of the utility model art
For personnel, without departing from the concept of the premise utility, some simple deduction or replace, said structure can also be made
The scope of protection of the utility model should be all considered as belonging to.
