Abstract
The utility model relates to a pile head bar straightening spanner, including main force's pole, impetus draw -in groove, pulling force hook, its characterized in that: main force's rod end head welding impetus draw -in groove, the straight butt welding of pulling force hook connects on main force's pole, and the hook end position of pulling force hook in impetus draw -in groove top, and the impetus draw -in groove will need the reinforcing bar of alignment to block, for pulling force hook atress provides the fulcrum, to the main force's pole other end stress application during operation, utilize lever principle with the exerted crooked bar straightening of pile head. The utility model discloses mainly adopting lever principle, needing two spanners cooperation constructions to the bending point at unsettled position, bending point that the pile head exposes main muscle root only needs a spanner can. The utility model discloses the usable waste material of the preparation processing of spanner forms. The utility model provides an other alignment devices can't accomplish the difficult problem of the alignment work of all bending points alone, easy operation can accelerate construction speed simultaneously.
Description
Technical field
The utility model belongs to engineering construction field, relates to after filling pile head is abolished and exposes main muscle straightening field, particularly a kind of pile crown bar straightening spanner.
Background technology
At present, engineering field many employings bored concrete pile is as buildings or structures basis, and pile body reinforcing bar need enter superstructure; For ensureing pile crown concrete strength, during cast bored concrete pile, bored concrete pile top mark is high higher than the high 0.5 ~ 1.0m of design stake top mark, should be reached after some strength until pile body concrete and will be cut higher than design stake top level section pile crown.After bored concrete pile abolishes pile crown concrete, inevitably causing design stake top mark high is irregular curved shape with upper part reinforcing bar.At present comparatively conventional bar straightening method has: 1, make " F " shape spanner straightening method by oneself, 2, hydraulic pressure straightening bending apparatus straightening method, 3, oxygen, acetylene baking straightening method.When pile crown single steel bar occurs that multistage bends, self-control " F " shape spanner and hydraulic pressure straightening bending apparatus all cannot complete separately straightening work, adopt oxygen, acetylene to toast and then impact reinforcement property.
Summary of the invention
The purpose of this utility model in order to overcome above-mentioned prior art Problems existing and shortcoming, and provides a kind of pile head bar straightening spanner.The utility model, without the need to too much input, makes material and the reinforcing bar waste material in work progress can be utilized to process.
The technical solution of the utility model is:
Pile crown bar straightening spanner, comprise main force rod, impetus draw-in groove, tension hook, it is characterized in that: main force rod termination is welded force draw-in groove, the flat end of tension hook is welded in main force rod, and the hook end of tension hook is positioned at above impetus draw-in groove.Impetus draw-in groove blocks needing the reinforcing bar of straightening, provides fulcrum for tension hook is stressed, applies stress, utilize the moment reinforcement bar straightening that pile crown exposes by lever principle during operation to main force rod end.
Described impetus draw-in groove width is 35mm, and the degree of depth is 50mm.
The hook end bending radius of described tension hook is 25mm, and the flat end of tension hook and main force rod adopt two-sided welding, and fusion length is 100mm.
The crotch center of circle of described tension hook is corresponding with the middle point vertical of impetus draw-in groove, and tension hook and impetus draw-in groove distance are 300mm.
The utility model mainly adopts lever principle, and the bending point for hanging part needs two spanner coordinative constructions, and the bending point of moment reinforcement root only needs a spanner.The making of the utility model spanner can utilize waste material to process.The utility model solves the difficult problem that other machine straightening devices cannot complete separately the straightening work of all bending points, simultaneously simple to operate, can accelerate speed of application.

Fig. 3 is structural representation of the present utility model;
Fig. 4 is for using straightening reinforcement construction schematic diagram of the present utility model.
Detailed description of the invention
The utility model will be further described by reference to the accompanying drawings.
As shown in Figure 1, Figure 2, Figure 3 shows, the utility model comprises main force rod 1, impetus draw-in groove 2, tension hook 3, it is characterized in that: main force rod 1 termination is welded force draw-in groove 2, and the flat end of tension hook 3 is welded in main force rod 1, adopt two-sided welding, fusion length is 100mm; And the crotch end of tension hook 3 is positioned at above impetus draw-in groove 2, the crotch center of circle of tension hook 3 is vertical corresponding with the central point of impetus draw-in groove, and tension hook 3 and impetus draw-in groove 2 are apart from being 300mm, and impetus draw-in groove 2 width is 35mm, the degree of depth is 50mm, and the hook end bending radius of tension hook is 25mm.Impetus draw-in groove 2 blocks needing the reinforcing bar of straightening, provides fulcrum for tension hook 3 is stressed, applies stress, utilize the moment reinforcement bar straightening that pile crown exposes by lever principle during operation to main force rod 1 end.
As shown in Figure 4, when straightening is carried out to the bending point of pile crown reinforcing bar hanging part, use two spanners of the present utility model, first the impetus draw-in groove of spanner I is aimed at bar bending point, then tension hook is caught on bar bending point top; After spanner I is in place, the tension hook of spanner II is caught on bending point, the impetus draw-in groove of spanner II blocks bending point lower rebar; During operation, two spanners should be symmetrical arranged, and apply downward power to spanner I, according to the size of the case of bending adjustment applying power of this bending point, ensure that spanner II is motionless simultaneously, thus can by the straightening of bar bending position.When straightening is carried out to pile crown reinforcing bar root bending point, only need a spanner of the present utility model to press aforesaid operations and perform.Successively the straightening construction that straightening operation can complete all bending points of single steel bar is carried out to each bending point by above step.
