Abstract

The utility model relates to a reinforcement bar strengthener, which is used for resolving the problem that the quality of installation for horizontal and vertical reinforcement bars cannot be effectively ensured due to distortion after the horizontal and vertical reinforcement bars are bent during the construction of the concrete structure reinforcement bar project. The reinforcement bar strengthener provided by the utility model comprises a handle, and the front end of the handle is a strengthening operation end; and the strengthening operation end with a concave shape consists of a 25-35 mm wide front pull finger, a 35-45 wide back pull finger and a 25-35 wide pull port, and is made by cutting a 28-32 mm thick steel plate; the handle is a Phi 35 mm steel tube which is 1100-1400 mm long. By using the supporting effect of the front and back pull fingers, the reinforcement bar strengthener provided by the utility model is used for conveniently adjusting partially bent reinforcement bars, so that the requirement for partial adjustment of the assembled reinforcement bars can be satisfied.

Description

A kind of bar straightening device
Affiliated technical field
The utility model relates to and a kind of the reinforcing bar installed and the local buckling of construction reserved steel bar are carried out straightening, transferred curved light instrument, especially can need the easy adjustment of vertical reserved steel bar of straightening to put in place to the part.
Background technology
At present; Common buildings engineering reinforcing bar is in the fabrication and installation process; And the adjustment of the own tiny bending of some reinforcing bars that collision forms in the construction and the bending of vertical reserved steel bar, and what adopt is that crowbar, manpower carry out limited adjustment, does not often reach the effect that reinforcement installation is checked and accepted.Reinforcing bar is after fabrication and installation are accomplished, because the operating space is little, reinforced steel bar strength is high, disturbs manyly in length and breadth to reinforcing bar, and operations such as pipeline, lightning-arrest down lead, template are interted construction local adjustment of reinforcing bar and positioning control are had relatively high expectations.As general adjustment means, adopt crowbar or manpower, method is coarse, is difficult to get a desired effect.And the reinforcement cover of beam, post, wall is generally at 15mm~35mm, and reinforcing bar has bending promptly to cause the topping deviation big slightly.General adjustment means are very limited; Because instrument lacks, the method limitation, the level and the vertical reinforcement that are difficult for not meeting installation requirement are adjusted to the right place, cause that local nodes reinforcing bar skewness, spacing are too small, the topping thickness differs; Cause difficulty to concrete pouring construction; Be difficult to vibrate, also influence the concrete formation quality, be easy to generate big defective.
Summary of the invention
In order to overcome the deficiency that can not effectively guarantee installation quality at construction work reinforcing bar horizontal reinforcement, vertical reinforcing bar in the fabrication and installation process because of flexural deformation; The utility model provides a kind of bar straightening device; It can not only carry out local straightening to level, vertical flexural deformation reinforcing bar bends with accent, and this straightener can be made easily, processes and operate.
The utility model solves the technical scheme that its technical problem adopted: a kind of bar straightening device, comprise handle, said handle front end is the straightening working end, said straightening working end is concave shape, by preceding pull toe, after pull toe and pull and mouthful constitute.
Said straightening working end adopts thick 28-32mm steel plate cutting processing to form, and it pulls mouthful width is 25-35mm, and the preceding toe width of pulling is 25-35mm, after to pull the toe width be 35-45mm; Said handle adopts Ф 35mm steel pipe, and it is long to be 1100mm-1400mm; The tail end of said straightening working end inserts in the handle steel pipe and welding.
The beneficial effect of the utility model: can when satisfy the reinforcement installation quality, effectively reduce labour intensity, increase work efficiency, the reinforcement installation later stage is carried out the requirement of quality fine setting to meet concrete work, simple for production, use flexibly.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is the bar straightening device structural representation of the utility model:
Fig. 2 is the main sketch map of looking in the straightening working end of the utility model.
Among the figure: 1. before pull toe, 2. pull mouth, pull toe after 3., 4. soldered, 5. handle.
The specific embodiment
Like Fig. 1, shown in 2, the utility model comprises handle 5, and handle 5 front ends are the straightening working end.The straightening working end is concave shape, by preceding pull toe 1, after pull toe 3 and pull mouthfuls 2 and constitute.The straightening working end is welded on handle 5 terminations.
The material of straightening working end be thick 30mm steel plate through the processing cutting form 30mm wide pull mouthfuls 2 and the forward and backward toe of pulling.Before pull toe 1 with after pull toe 3 width be respectively: 30mm, 40mm.The straightening working end is welded on that 1200mm is long, on the steel pipe of Ф 35 (tail end of straightening working end insert 50mm welds again in the handle steel pipe, to gain in strength), steel pipe is as operating grip.Forward and backwardly pull toe and pull mouth because of this straightener has, the reinforcing bar that needs straightening is stuck in pulls in the mouth, the hand-held operation handle can be accomplished the adjusting range that needs, and reaches the purpose that the reinforcing bar fine tune required and met the reinforcing bar acceptance criteria.
For guaranteeing the bar straightening needs, to pull a mouthful width and be controlled at 30mm, the degree of depth is controlled at 40mm, straightening working end and steel pipe handle firm welding.
The utility model is convenient to processing, and is firmly practical, and adjustment flexibly.The supporting role of pulling toe before and after utilizing, more convenient small size straightening local buckling reinforcing bar when satisfying the reinforcement installation quality requirement, uses flexibly, effectively reduces labour intensity, increases work efficiency.

Claims (2)

1. bar straightening device, it is characterized in that: comprise handle, said handle front end is the straightening working end, and said straightening working end is concave shape, by preceding pull toe, after pull toe and pull and mouthful constitute.
2. bar straightening device according to claim 1 is characterized in that; Said straightening working end adopts thick 28-32mm steel plate cutting processing to form, and it pulls mouthful width is 25-35mm, and the preceding toe width of pulling is 25-35mm, after to pull the toe width be 35-45mm; Said handle adopts Ф 35mm steel pipe, and it is long to be 1100mm-1400mm; The tail end of said straightening working end inserts in the handle steel pipe and welding.
