Abstract
The utility model discloses a cross arm for a cement pole, which comprises a top plate, an upper lateral plate, a lower lateral plate, a front reinforced plate and a rear reinforced plate, wherein an arc base plate is arranged at one end of the upper lateral plate and one end of the lower lateral plate, and an intermediate reinforced plate is arranged between the base plate and the top plate. The cross arm for the cement pole has the advantages that the stressed structure of the cross arm is improved, and the bottom with the weakest intensity of the cross ram is subjected to structure reinforcement; with the adoption of the arc base plate, the cross arm can be prevented from being twisted and out of balance; and the cross arm is simple in structure and low in making cost.
Description
Technical field
The utility model relates to a kind of cross-arm that is used for supporting electric wire on the electric pole that is installed in, specifically a kind of cross-arm that is installed on the cement pole.
Background technology
At present; Be press-fitted rack ceases to be busy road in China town and country and adopt the quantity of cement electric wire phase to account for 90%, the cross-arm of used supporting electric wire is divided into two kinds on the cement pole, and a kind of is as cross-arm by angle steel; Last fixing support rack; Bottom linkage triangle shape support, the support lower end connects anchor ear, and defective is that cross-arm is prone to distortion, unbalance.Another kind sticks up formula for split, is welded into by steel plate, and inside has cavity, needs special supporting polyhedron anchor ear during installation, and defective is a complex structure, and cost of manufacture is high, and weight is big.
The utility model content
To the weak point that prior art exists, the utility model in provide a kind of simple in structure, can strengthen the bottom ability to bear, prevent that cross-arm distortion, unbalance cement pole from using cross-arm.
To achieve these goals; The technical scheme of the utility model is: a kind of cement wire rod bar is used cross-arm; Comprise top board, epipleural, lower side panel, preceding stiffener, back stiffener, said side plate one end up and down is provided with the base plate of arc, stiffener in the middle of between base plate and top board, being provided with.
The beneficial effect of the utility model is: this utility model cross-arm has improved the force structure of cross-arm, and the bottom that cross-arm intensity is the weakest is carried out structure-reinforced, has increased the base plate of an arc, can prevent cross-arm distortion, unbalance, simple in structure, and cost of manufacture is low.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the vertical view of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing and concrete embodiment the utility model is done explanation further.
Know by Fig. 1, Fig. 2; The cement wire rod bar of the utility model is used cross-arm; Comprise top board 3, epipleural 6, lower side panel 7, preceding stiffener 5, back stiffener 1, an end of said epipleural 6 and lower side panel 7 is provided with the base plate 4 of arc, stiffener 2 in the middle of between base plate 4 and top board 3, being provided with.This cross-arm has improved the force structure of cross-arm, and the bottom that cross-arm intensity is the weakest is carried out structure-reinforced, has increased the base plate 4 of an arc, can prevent cross-arm distortion, unbalance, simple in structure, and cost of manufacture is low.
The technical scheme of the utility model is not limited to the restriction of above-mentioned specific embodiment, and every technology distortion of making according to the technical scheme of the utility model all falls within the protection domain of the utility model.
