Away from.
Utility model content
For solving the problems referred to above, this utility model provides a kind of box beam top board prestressed rib positioning device, is installed on case
Top surface of the beam, auxiliary positioning web reinforcement, can quickly determine box beam top board presstressed reinforcing steel position, it is to avoid unnecessary web reinforcement
Move or cut, it is ensured that main steel bar stress position is accurate, it is ensured that the overall stress of bridge is safe and stable.
For achieving the above object, the technical scheme that this utility model is taked is:
A kind of box beam top board prestressed rib positioning device, including transversely prestressed bars positioning framework, presstressed reinforcing steel duct width
Degree actuator, vertical prestressing bar auxiliary positioning hole, presstressed reinforcing steel space regulator composition, transversely prestressed bars positioning framework leads to
Crossing pin to be connected with box girder formwork, transversely prestressed bars positioning framework is adjusted by presstressed reinforcing steel cell wide by two positioning frameworks
Joint device be connected constitute, adjacent two transversely prestressed bars positioning frameworks by presstressed reinforcing steel space regulator be connected, described laterally
Presstressed reinforcing steel positioning framework is provided with some vertical prestressing bar auxiliary positioning holes.
As preferably, described presstressed reinforcing steel cell wide actuator is flower basket bolt；
As preferably, described presstressed reinforcing steel space regulator is flower basket bolt；
As preferably, described vertical prestressing bar auxiliary positioning hole is 3-5cm seamless steel pipe.
This utility model has the advantages that
Simple in construction, easy to use, Financial cost is low, applied widely, can be accurately positioned top board deformed bar
Position, it is to avoid affect the position of web reinforcement, reduces individual labor intensity, improves production efficiency, reduction of erection time.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model embodiment.
Detailed description of the invention
In order to make the purpose of this utility model and advantage clearer, below in conjunction with embodiment, this utility model is entered
Row further describes.Should be appreciated that specific embodiment described herein, and need not only in order to explain this utility model
In limiting this utility model.
As it is shown in figure 1, this utility model embodiment provides a kind of box beam top board deformed bar quick positioning mechanism, its
It is characterised by, determines including transversely prestressed bars positioning framework 1, presstressed reinforcing steel cell wide actuator 4, vertical prestressing bar auxiliary
Hole 5, position, presstressed reinforcing steel space regulator 3 form, and transversely prestressed bars positioning framework 1 is connected with box girder formwork by pin 2, horizontal
It is made up of by presstressed reinforcing steel cell wide actuator 4 is connected two positioning frameworks to presstressed reinforcing steel positioning framework 1, adjacent two
Transversely prestressed bars positioning framework 1 is connected, on described transversely prestressed bars positioning framework 1 by presstressed reinforcing steel space regulator 3
It is provided with some vertical prestressing bar auxiliary positioning holes 5.
Described presstressed reinforcing steel cell wide actuator 4 is flower basket bolt；

Described vertical prestressing bar auxiliary positioning hole 5 is 3-5cm seamless steel pipe.
In the present embodiment, described transverse prestressed reinforcing steel bar fixed frame 1 and box girder formwork use pin 2 to fix, and conveniently tear open
Unload, before laying, correctly to adjust presstressed reinforcing steel spacing 3 and cell wide actuator 4 according to drawing spacing.Vertical muscle location
Hole 5 can be actual from Row sum-equal matrix according to engineering, and simply reinforcing bar is at vertical auxiliary locator.
When being originally embodied as using, before placing web reinforcement, first fixing this device at box beam end face, advance reservation is good
Transversely prestressed bars and the position on vertical prestressing bar top, then installation drawing requires to place web reinforcement, is laying web
To guarantee during reinforcing bar that this device is fixed, occurs without skew.Treat that web reinforcement is placed to terminate, in the duct reserved
Top board deformed bar pipeline is conveniently placed in position, it is to avoid the secondary of web reinforcement moves or cuts, and improves construction effect
Rate.
Originally being embodied as simple in construction, easy to use, Financial cost is low, applied widely, can be accurately positioned top board pre-
The position of stress reinforcing bar, it is to avoid affect the position of web reinforcement, reduces individual labor intensity, improves production efficiency, reduction of erection time.
The above is only preferred implementation of the present utility model, it is noted that come for those skilled in the art
Saying, on the premise of without departing from this utility model principle, it is also possible to make some improvements and modifications, these improvements and modifications also should
It is considered as protection domain of the present utility model.
