Abstract
The utility model discloses a chuck for fixing a telegraph pole. The chuck comprises a concrete structure and a rebar structure, wherein the shape of the cross section of the concrete structure is similar to the shape of U, the concave portion of the concrete structure is in the shape of an arc, two bolt holes are formed in the concrete structure and symmetrically formed in the two sides of the concave portion, the clear distance between the two bolt holes is the diameter of the corresponding bottom end of the telegraph pole, the rebar structure is arranged in the concrete structure, the rebar structure comprises at least three rebar layers, each rebar layer comprises a first main rebar and a second main rebar, the first main rebars are linear, the second main rebars are bent in the concave portion, two first hoops are arranged at the two ends of each rebar layer, two second hoops are arranged on the rebar layers where the concave portion is located, the diameter of each first hoop and the diameter of each second hoop are both 6 mm, and the diameter of each first main rebar and the diameter of each second main rebar are both 8 mm. The chuck has the advantages of being convenient to install, short in construction time and high in bending resistance and tilt resistance.
Description
Technical field
The utility model relates to the fastening devices of electric pole, specifically a kind of chuck of securing electric lines bar.
Background technology
No matter be the electric pole that concrete wire pole or other materials are made at present, substantially be to be all from top to bottom truncated cone, conventionally the mounting means on its ground is all first to dig a foundation ditch in installation position, the minimum inscribed circle diameter of foundation ditch is greater than electric pole electric pole root diameter (RD), then select suitable poling method according to actual conditions, by in upright electric pole foundation ditch, then slabstone, soil are backfilling in foundation ditch and tamp and fix, fixture is not set.The electric pole poor stability of installing like this, be subject to for a long time under the effect of external force, easily run-off the straight, when serious, even cause that electric pole fractures, topples over, electric wire is broken, cause power failure and the cable phenomenon of contacting to earth, near people and other life entities are formed to great threat, even lead to major accident, the life to people and property cause irremediable loss.And the electric pole fastening devices and the method that adopt at present, some is only strengthened the cavity of electric pole, and its resistance to fracture improves, but it anti-ly topples over ability without remarkable improvement; Although some has played certain reinforcement effect to electric pole, owing to being subject to structural limitations, its Area of bearing is little, the anti-ability DeGrain of toppling over, fracture; Also some constructs with pre-buried hole shape adapts and constructs frame in pre-buried hole, then be connected as a single entity and be used as its fastening devices constructing in frame concreting and electric pole root, but exist, shortcoming loaded down with trivial details, that the engineering time is long is installed, in addition majority adopts chucks as fastening devices at present, there is sturdy and durable, corrosion-resistant, the advantage such as heatproof is poor, cracking resistance, but existing chuck structure, due to its bending resistance square ability, the effect reaching is not good enough.
Utility model content
For the problems referred to above, the problem that the utility model quasi-solution is determined be to provide a kind of easy for installation, the engineering time is short, the chuck of bending resistance and the strong securing electric lines bar of anti-tilt capability.
For achieving the above object, the utility model is by the following technical solutions: a kind of chuck of securing electric lines bar, comprise concrete structures and bar construction, the shape of cross section of described concrete structures is similar to " recessed " shape, the recess of described concrete structures is shaped as circular-arc, in described concrete structures, be provided with two bolts hole, two described bolts hole are symmetricly set on described recess both sides, the clear distance of described two bolts hole is corresponding electric pole bottom diameter, described bar construction is arranged in concrete structures, described bar construction comprises at least compound steel muscle layer, every layer of steel bar layer includes main reinforcement one and main reinforcement two, described main reinforcement one is linear, described main reinforcement two is bending at described recess, the two ends of described steel bar layer are equipped with two stirrups one, the steel bar layer at described recess place is provided with two stirrups two, the diameter of described stirrup one and described stirrup two is 6mm, the diameter of described main reinforcement one and described main reinforcement two is 8mm.
As preferably, described steel bar layer quantity is four layers.
Effective achievement of the present utility model: the circular-arc design that in the utility model, concrete structures recess presents according to electric pole edge, and be provided with bolt hole, assembly connection U-shaped screw in installation process, be close to electric pole completely and be fixed, do not need scene to construct, easy for installation, engineering time is short, add inner unique steel bar layer structure design, not only have advantages of sturdy and durable, corrosion-resistant, heatproof is poor, cracking resistance, and has long-time anti-inclination anti-bending strength.
In sum, the utlity model has easy for installation, the engineering time is short, bending resistance and the strong feature of anti-tilt capability.
