Description
Technical field
The present invention relates to a kind of bar bending straightener, more particularly to one kind can be directed to high tensile reinforcement job site large area
Standardization bending, straightening, the portable many bending of the function high tensile reinforcement at most straighteners for training off angle.
Background technology
In Bridge Construction, run into that Bridge Main Pier dimension of platform is big, clump of piles diameter is big, densely distributed, bar diameter is big
Situation, such as:Main pier sets 50 D2.0m drilled pile, and steel reinforcement cage cage bar is Φ 28mm, in this case bridge drilled pile loudspeaker
The perpendicular muscle crotch of mouth can exceed casing, the decentralization of influence steel reinforcement cage, positioning, and expanding casing diameter can cause concrete to waste, and press
According to《Railway concrete Construction Technology guide》The square hook length for providing HRB400 Φ 28mm is 24cm, for
D2.0m（Steel reinforcement cage diameter 185cm, steel pile casting diameter 220cm）Drilled pile, top cage erects maximum gauge after muscle standard hook pre-bending and is
185+24 × 2=233cm, the size is more than steel pile casting diameter, influence steel reinforcement cage decentralization, therefore perpendicular muscle pre-bending is infeasible, furthermore, it is curved
Hook pre-bending cuts to the later stage, lifts pile crown construction, so, make top cage horn mouth using palintrope legal system.
Engineering early stage drilled pile workload is big, and the duration is tight, top cage horn mouth and crotch influence cushion cap reinforcement installation, in view of holding
The platform construction period is tight, and cushion cap bottom layer of the reinforcing steel mesh sheet is intensive, and reinforcing bar lifting, installation exercise amount are big, are not disturbing cushion cap bar-mat reinforcement
Fast and high quality completion bending construction is very necessary on the premise of piece is constructed, and is amputated in bearing platform construction, lifts meeting during pile crown
Knock over, bend part drilled pile cage bar, straightening workload is big, and carries out the fast velocity modulation of large-diameter and high-strength reinforcing bar without suitable mechanical
Directly, construction speed is influenceed.Steel reinforcement abutting joints need to be pre- inclined, needs to exist because a part of reinforcing bar occurs unavoidably in a variety of causes in reinforced bar engineering
Scene carries out the pre- inclined construction of docking, and difficulty of construction is big, is not suitable for applying big machinery.
Bridge drilled pile horn mouth is erected 90 ° of muscle upper end normal bend and made using palintrope method, and bar diameter is big, intensity
Height, and commonly bend, time-consuming for straightening process operation, efficiency is low, of poor quality, therefore does not meet modern fine, mechanization, human nature
The demand for development of change.
The content of the invention
It is durable in use the invention aims to overcome the shortcoming of above-mentioned background technology there is provided one kind is simple to operate, continuously
Ability to work is strong, the low portable many bending of the function high tensile reinforcement at most straighteners of maintenance cost.
The technical scheme is that：A kind of portable many bending of function high tensile reinforcement at most straighteners, including support, it is curved
Actuating unit described in bent bar straightening mechanism and actuating unit is jack, provided with vertically handle in the main body wall of jack
Hand, provided with horizontal handle on the sealing flange of jack, the push rod end of jack is provided with bending bar straightening mechanism, and described is curved
Bent bar straightening mechanism is detachable bending apparatus, and it includes two different radii notches and a straight drift angle notch, described support bag
Symmetrically arranged two support frames and the horizontal company of reinforcement being located between two support frames are included, is provided with the bottom of two support frames
With the support base of reinforcing bar groove, the lower section of plane, two support frame tops where the plane where two support frames is in push rod
Portion is fixedly connected with sealing flange, and any one of two described support frames is provided with adjustable limiting device, the adjustable limiting device
Collapsing length by buckle control, the bottom of adjustable limiting device is connected by bearing pin with support frame.
The beneficial effects of the invention are as follows：The head that bends, straightening construction, docking can be quickly standardized to high strength cast iron in advance
The equipment of drift angle construction, possesses good performance, and power is sufficient, light and flexible, can apply to steel reinforcement abutting joints termination drift angle
Bend, bar straightening, the similar construction such as rebar standardses elbow-making；Present invention design bending parameters are unified, construction quality is high, certainly
Dynamicization bending construction, reduces labor intensity, efficiency of construction is high, construction space is small, does not influence other processes to construct, be conducive to the duration
Control, and it is simple to operate, durable in use, continuous ability to work is strong, and maintenance cost is low, has a extensive future.
