Background
At present, with the rapid development of a reinforced concrete structure, particularly during the construction of an underground concrete structure, the application of a deep foundation pit is more and more common, and the enclosure structure plays a role in temporary support and safety in the construction of the deep foundation pit. After the construction of the cast-in-situ bored pile or the underground diaphragm wall is completed, pile head concrete needs to be further broken, and next-step crown beam supporting construction is carried out. And the pile head reserved steel bars need to be straightened before the top beam steel bars are bound according to the specification and design requirements so as to better meet the stress requirement of the connecting part.
During actual construction, the alignment of pile head reinforcing steel bars directly relates to the construction efficiency and quality. The current steel bar straightening commonly adopts the mode: the steel bar is fixed by using a spanner or a steel pipe, and the straightening of the bent part of the steel bar is finished manually. This kind of crooked reinforcing bar alignment mode has that artifical physical demands consumes greatly, and the alignment can't be accomplished by human power alone to some great reinforcing bars of diameter even, consequently, accomplishes the alignment of crooked reinforcing bar through crooked reinforcing bar alignment instrument and can improve the efficiency of construction and practice thrift the cost.
SUMMERY OF THE UTILITY MODEL
The utility model provides an above-mentioned technical problem to exist among the prior art provides a pile head major diameter crooked reinforcing bar alignment instrument.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
a pile head major diameter bend bar straightening tool, includes:
a jacking force rear seat;
two U-shaped steel bar fixing rings which are arranged in parallel from top to bottom; the opening sides of the two reinforcing steel bar fixing rings are fixed with the same side of the jacking force rear seat; a radian matched with the shape of the steel bar is arranged on one side of the steel bar fixing ring opposite to the jacking force rear seat;
the jack is arranged between the jacking force rear seat and the reinforcing steel bar fixing ring; the jack comprises a small oil cylinder and a controller; the bottom of the cylinder body of the oil cylinder is fixed with the jacking force rear seat; during straightening, the oil cylinder piston extends out towards the side where the reinforcing steel bar fixing ring is located; after straightening, the oil cylinder piston retracts to the original position.
Further, the jack is arranged between the two reinforcing steel bar fixing rings in the vertical direction.
Furthermore, connecting ribs are arranged on the periphery of the side wall of the cylinder body of the jack; the end part of the connecting rib is welded and fixed with the reinforcing steel bar fixing ring.
Further, the jacking force backseat is made of a high-strength steel plate having a thickness of 2 cm.
The utility model has the advantages and positive effects that:
1) the utility model discloses simple structure, the manufacturing of being convenient for can form at job site temporary welding equipment, and it is also comparatively convenient to use, can solve at the artifical unable alignment of pile head major diameter bending steel bar and the big problem of labour consumption. The steel bar fixing ring with the U-shaped structure can enable the whole tool to be more stable, and the bent steel bar has better stress points, so that the stability of the whole tool and the bent steel bar is improved;
2) the jack is arranged between the two reinforcing steel bar fixing rings in the vertical direction, so that the reinforcing steel bars are uniformly stressed during straightening;
3) the setting of splice bar can make the solid fixed ring of reinforcing bar and be connected more firmly with the jack.
4) The jacking force rear seat is made of a high-strength steel plate with the thickness of 2cm, and can meet the requirement of straightening and stressing of the reinforcing steel bar when the jack jacks in.
