[utility model content]
This utility model is mainly solving the technical problems that provide one to extend gradual change type Ω shape ground compensation device, it is possible to logical
Cross bigger shearing strain to resist subsiding crack both sides shear stress, thus ensure that both sides body of wall or the integrity of reserved ironware.
For solving above-mentioned technical problem, the technical scheme that this utility model uses is: a kind of prolongation gradual change type Ω shape
Ground compensation device, including overlap joint welding section: can be used in ground connection earial drainage；Gradual change distorts excessive section: can increase ground connection band iron and scratch
Degree, regulates direction, and change vertical shear is horizontal shear force；Ω shape semicircle compensator；Be prevented from surrounding cables ditch, weldment draws
Split；Wherein, the excessive section of described gradual change distortion is connected with described Ω shape semicircle compensator and extends in left-right direction；Described overlap joint
Welding section distorts excessive section with described gradual change and is connected and extends in left-right direction.
Further, described Ω shape semicircle compensator is connected in the way of an angle of 90 degrees with the described gradual change excessive section of distortion.
Further, the bending diameter of described Ω shape semicircle compensator is 60 millimeters, and described Ω shape semicircle compensator
A length of 135 to 175 millimeters.
Further, described gradual change distorts excessive section and is diagonally divided into two faces, and said two face is in the way of 45 degree of angles
It is connected.
Further, described overlap joint welding section is connected with the vertical plane in said two face in vertical manner.
Further, described overlap joint welding section is connected in the way of 145 degree of angles with described vertical plane.
Further, the 1 to 3 of a length of described prolongation gradual change type Ω shape ground compensation device width of described overlap joint welding section
Times；Described gradual change distorts a length of 50 to 140 millimeters of excessive section.
The invention has the beneficial effects as follows: the former Ω shape ground compensation device crossing cable duct " is longitudinally arranged, indulges by this utility model
To shearing, longitudinal surface stress " change into " longitudinally fade to horizontally disposed, longitudinal shear, horizontal plane stress ".Additionally, gradual change is turned round
Bent excessively section, it is possible to resist subsiding crack (movement joint) both sides shear stress by bigger shearing strain, thus ensure that both sides body of wall
Or the integrity of reserved ironware.And can by increase itself deflection dissolve uneven settlement of foundation to concrete or
The destruction of brick component or impact, meet furrow bank and bottom deformation seam indwelling is reasonable, and sealant sealing is uniform, without cracking, beautiful
See specification.
[accompanying drawing explanation]
In order to be illustrated more clearly that this utility model embodiment or technical scheme of the prior art, below will be to embodiment
Or the required accompanying drawing used is briefly described in description of the prior art, it should be apparent that, the accompanying drawing in describing below is only
It is embodiments more of the present utility model, for those of ordinary skill in the art, in the premise not paying creative work
Under, it is also possible to other accompanying drawing is obtained according to these accompanying drawings.
Fig. 1 is structural representation of the present utility model.
In accompanying drawing, the labelling of each parts is as follows: 101, the first overlap joint welding section；102, the second overlap joint welding section；201, first
Gradual change distorts excessive section；202, the second gradual change distorts excessive section；211, first；212, second；3, Ω shape semicircle compensator.
[detailed description of the invention]
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under making creative work premise
The every other embodiment obtained, broadly falls into the scope of this utility model protection.
Extend gradual change type Ω shape ground compensation device as it is shown in figure 1, a kind of, take including the first overlap joint welding section 101 and second
Connect welding section 102: regulatory requirements band iron is crossing movement joint, need to do arc compensation device, simultaneously code requirement band iron during subsiding crack
The length that need to use double-width uses three boxing overlap joints, to meet the effect of reliable ground earial drainage.
First gradual change distorts excessive section 201 and the second gradual change distorts excessive section 202: increases transition effect and is to increase ground connection
Band iron amount of deflection, and be adjusted changing to the direction of deformation Ω shape compensator, become hard staight scissors and be cut to horizontal shear；
Ω shape semicircle compensator 3；Increase the sedimentation and deformation distortion allowance to ground connections, by Ω compensator section self
Deformation eliminates differential settlement and brings impact, prevents surrounding cables ditch, weldment drawing crack.
A kind of gradual change type Ω shape ground compensation device that extends, general uses zinc-plated band iron to make, and with substation grounding system
The material of system keeps consistent.Including Ω shape semicircle compensator 3, around both sides respectively with first gradual change distort excessive section 201 and
